    Multi-fitting plate and set of plates comprising such a multi-fitting plate
    The invention relates to a multi-connector plate for the simultaneous connection of several connectors of the fluidic and / or electrical type. The invention also relates to a set of plates comprising such a multi-connector plate.
    It is known to bring together and lock two multi-connector plates by a locking device carried by one of the two plates and comprising a rotating element as well as a locking shaft movable in translation, a device for transforming the rotational movement of the rotating element in translational movement of the shaft being interposed between the locking shaft and the rotating element. The rotating element is actuated by an operator when the couplings need to be coupled or uncoupled.
    WO 2013 074 047 describes in particular a lever intended to be actuated by an operator and driving in rotation a rotating element inside a frame. A control finger is integral in rotation with the rotating element and is engaged in a sliding locking shaft, guided in translation in the frame. The flared end of the locking shaft cooperates with locking balls housed in a locking ring pushed back by a spring towards the end of the locking shaft. This ring engages in a socket of a second plate at the connection. The backward movement of the locking shaft 2 then causes the engagement of the locking balls in the bushing then the bringing together of the plates and the connection of the fittings. A pin is used to lock the position of the rotating element in the approached coupled configuration in which the fittings are coupled.
    Similar devices are also described in JPH 07 208 673 and US 8 864 179.
    These multi-connector plates are intended to be placed as close as possible to the machines, injection presses for example, which the connectors carried by the multi-connector plates make it possible to supply with fluid or electricity and, depending on the installation, the access of the operator to the locking device may be limited.
    During connection, the fluidic connections have spring-mounted valves which create repulsion forces which the locking device must counteract. This implies that the operator must sometimes exert a significant effort at mating.
    It is these drawbacks that the invention intends to remedy by proposing a new multi-connector plate which is more ergonomic for the operator, in particular in terms of access to the locking device or repulsion efforts.
    To this end, the invention relates to a multi-connector plate for the simultaneous connection of several fluidic and / or electrical type connectors, the plate comprising a locking device in a direction of connection of connection elements carried by the plate to complementary connection elements carried by a second plate, the locking device comprising a fixed frame on the plate, locking members and a drive mechanism, the drive mechanism comprising:
    - a rotating element movable in rotation in the frame, between a uncoupled configuration and a coupled configuration of the plate,
    a sliding element movable in translation relative to the frame in the connection direction and which cooperates with the locking members, the locking members being movable relative to the sliding element between a first unlocked position where they free a passage for the second plate relative to the sliding element, and a second locked position where they are able to secure the sliding element and the second plate in the connection direction,
    one or more elements for transforming the rotational movement of the rotary element into the translational movement of the sliding element, in the uncoupled configuration, the sliding element is in an advanced position relative to the frame and the locking members are able to come into their first unlocked position, in the coupled configuration, the sliding element is in a retracted position relative to the frame and the locking members are in their second locked position.
    This multi-fitting plate is characterized in that the locking device also comprises:
    - several click notches secured to an element of the drive mechanism and juxtaposed in the direction of movement relative to the frame of the element of the drive mechanism, the click notches comprising a final notch and at least one intermediate notch , and
    - a movable pawl in a housing of the frame and pushed back by a spring in the direction of one of the pawl notches;
    and in that :
    - when the pawl cooperates with the intermediate notch, the pawl limits the movement of the sliding element towards its advanced position to an intermediate position between the advanced position and the retracted position, and
    - in the coupled configuration, the pawl cooperates with the final notch and maintains the sliding element in the retracted position.
    Thanks to the invention, the ratchet system allows the operator to exercise successive small amplitude rotations of the rotating element to obtain a gradual bringing together of two multi-fitting plates and a connection of the fittings, which allows a better ergonomics in case of difficult access and significant efforts to provide.
    According to advantageous but not compulsory aspects of the invention, such a multi-connector plate can incorporate one or more of the following characteristics, taken according to any technically admissible combination:

    - The click notches are provided on the rotating element.
    - Each intermediate and final click notch is delimited by a bottom and an abutment surface which protrudes from the bottom and in the engagement configuration in one of the intermediate and final click notches, the pawl forms an obstacle to the abutment surface in a direction of movement of the element of the drive mechanism with click notches between the coupled configuration and the uncoupled configuration.
    - A click amplitude of the drive mechanism corresponds to a rotation of 20 ° to 40 ° of the rotating element in the frame.
    - The depth of each intermediate notch is variable.
    - The depth of the final click notch is greater than the maximum depth of the intermediate click notches.
    - The pawl has a visual marker, visible from the outside of the locking device except when the pawl cooperates with the bottom of the final click notch.
    - The locking members are in their second locked position as soon as the pawl is engaged in the first or second intermediate notch.
    - The rotating element is integral in rotation with a grip profile for a tool, this grip profile being accessible from outside the frame.
    - The elements for transforming the rotary movement of the rotary element into the translational movement of the sliding element include a control finger whose central longitudinal axis is offset from the axis of rotation of the rotary element, the finger control being linked in rotation about the axis of rotation with the rotating element and linked in translation with the sliding element in the direction of connection, the sliding element being guided by a housing of the frame in its translational movement.
    - The sliding element comprises a locking shaft with a reduced diameter portion and a flared end, a locking ring surrounds the locking shaft and houses locking balls forming the locking members, the locking ring being movable by relative to the locking shaft between a retracted position in which the locking balls are able to come into their first unlocked position, with the locking balls cooperating with the portion of reduced diameter and being set back from the external radial surface of the locking ring, and an advanced position in which the locking balls are pushed radially by the flared end into their second locked position, projecting from the external radial surface of the locking ring, a spring returning the locking ring towards its advanced position.

    FIG. 1 represents a set of plates E comprising a first plate P1 and a second complementary plate P2. The first plate P1 comprises connection elements 2, each connection element 2 being arranged at the end of a fluid or electricity pipe. The second plate P2 comprises connecting elements 4 complementary to the connecting elements 2, each complementary connecting element 4 being arranged at the end of a fluid or electricity pipe. Each connector element 2 is intended to be coupled to a complementary connector element 4 to form a connector R of fluidic or electrical type by connecting their respective conduits, not shown. The first P1 plate and the second plate
    P2 are multi-connector plates for the simultaneous connection of several connectors, six in number in the example shown.
    The plates P1 and P2 extend along planes perpendicular to a direction Z which also constitutes a direction of connection of the first plate P1 with the second plate P2. This connection direction Z is the direction in which the plates P1 and P2 are brought together during a locking and connection operation. The Z direction is vertical in this example, but can be oriented differently.
    In the following description, the term "front" denotes for one element of the plate P1 one side facing the opposite plate P2, and the term "rear" the opposite side with respect to the opposite plate P2.
    The terms "axial" and "radial" are used to designate surfaces of an element respectively perpendicular or surrounding a central axis of reference of the element. The terms "axially" and "radially" designate a direction respectively parallel or orthogonal to this reference axis.
    For an element considered, the terms "internal" and "external" designate parts or surfaces oriented respectively on the side of a central axis of this element or on the side opposite to the central axis of this element.
    For an element considered, the terms "circumferential" and "circumferentially" refer to a part, surface or orientation extending in a direction of revolution around a central reference axis of this element.
    The first plate P1 is movable relative to the second complementary plate P2, which is intended to be fixed on a machine, for example an injection press. The first plate P1 notably includes a handling handle 1 for the operator to take hold of the plate P1.
    The first plate P1 is equipped with a locking device 6, which is adapted to bring the first plate P1 closer to the second plate P2 in the connection direction Z, and to lock the two plates P1 and P2 in the coupled position of the elements of connection 2 and 4. When the plates P1 and P2 are brought together and locked, all the connections carried by the first and second plates P1 and P2 are simultaneously connected.
    The plates P1 and P2 include guide elements making it possible to guide their approach. The plate P1 for this purpose comprises a guide element formed by a cylindrical column 8, extending parallel to the direction of connection Z, and the second plate P2 comprises a guide element formed by a cylindrical sleeve 10 also extending in parallel to the connection direction Z. The internal diameter of the sleeve 10 is substantially equal to the external diameter of the column 8, which allows the insertion of reduced clearance of the column 8 in the sleeve 10 when the plates P1 and P2 are brought together. . As a variant, the column 8 can be carried by the second plate P2 and the sleeve 10 by the plate P1.
    The second plate P2 is equipped with a locking sleeve 12 capable of cooperating with the locking device 6 for bringing together and locking the plates P1 and P2. The locking sleeve is centered on an axis Z12 parallel to the direction Z during coupling. The locking sleeve 12 is fixed on the second plate P2, therefore integral with the second plate P2, and includes an internal bore 120 and a constricted part 122 with a narrowed internal diameter, on the side of the first plate P1 being coupled. . The internal diameter of the bore 120 is enlarged relative to that of the constricted part 122.
    The locking device 6 comprises a frame 14 and a drive mechanism 16. The frame 14 is fixed to the plate P1 by screws not shown and is therefore integral with the plate P1, in particular in the direction Z. The mechanism drive 16 comprises a rotating element 18 which is rotatable with respect to the frame 14 about a central longitudinal axis X18 of the rotating element 18, perpendicular to the connection direction Z. This rotating element 18 is guided in its rotation by relative to the frame 14 along the axis X18 by a cylindrical housing 140 of the frame 14 centered on the axis X18.
    The rotating element 18 comprises a hexagonal projection 180 which is coaxial with the axis X18 and which extends out of the frame 14 perpendicular to the connection direction Z. This hexagonal projection 180 allows a tool 34 of the key type, having a complementary hexagonal shape, can be engaged by an operator around the hexagonal projection 180 so as to actuate the locking device 6.
    As shown in Figures 1 and 7, a visual reference 182 is integral with the rotating element 18 to identify the angular position of the rotating element 18 around the axis X18. This visual reference 182 is visible from outside the frame 14 around the hexagonal projection 180.
    The drive mechanism 16 also comprises a sliding element 20 which is movable in translation relative to the frame 14 along an axis Z20 parallel to the connection direction Z.
    The locking device 6 also comprises locking members which are in this example formed by balls 22, for example eight balls 22, the sliding element 20 cooperating with the locking balls 22 so that the locking balls 22 are movable with respect to the sliding element 20, between a first retracted unlocked position, shown in FIG. 3, and a second protruding locked position, shown in FIG. 6. In the first unlocked position, the locking balls 22 are retracted out a reception volume 23 disposed around the sliding element 20 and intended to partially receive the locking sleeve 12 of the second plate P2 and free the passage of the sleeve 12 relative to the sliding element 20 according to the Z20 axis. In this configuration, the sliding element 20 is free to slide along the axis Z20 relative to the sleeve 12, in particular in the constricted part 122.
    In their second locked position, the locking balls 22 protrude radially in the receiving volume 23 and when the sleeve 12 is engaged in the receiving volume 23, lock the sleeve 12 with the sliding element 20 along the axis Z by forming an obstacle to the separation of the first plate P1 from the second plate P2 along the axis Z, because the locking balls 22 are stopped by the portion of constricted diameter 122. The locking balls 22 are adapted to come in their first position retracted in an unlocked configuration of the locking device 6 and uncoupled from the plate P2, which allows the insertion or removal of the sliding element 20 in the locking sleeve 12.
    The sliding element 20 comprises a locking shaft 200. A locking ring 202 surrounds the locking shaft 200 with the possibility of axial displacement relative to the locking shaft 200 along the axis Z20 which is also a central axis longitudinal of the ring 202. The locking ring 202 houses the locking balls 22 by virtue of housings 202a passing through and inclined with respect to a direction perpendicular to the axis Z20. The housings 202a are tightened at their external outlet so as to maintain each of the balls 22 in its housing 202a. A spring 204 is interposed between the locking shaft 200 and the locking ring 202 and pushes the locking ring 202 towards an advanced position relative to the locking shaft 200, represented in FIG. 6. In FIG. 3, the locking ring 202 is in a rear rearward position relative to the locking shaft 200, the spring 204 being more compressed than when the locking ring 202 is in its advanced position relative to the locking shaft 200.
    The locking ring 202 comprises a front shoulder 202b capable of coming into axial abutment against the locking sleeve 12 during coupling along the axis Z, and a rear shoulder 202c adapted to come into abutment against the plate P1. The front shoulder 202b and an external radial surface 202d of the locking ring 202 define the receiving volume 23 of the sleeve 12 around the sliding element 20.
    The locking shaft 200 includes a front part 200A and a rear part 200B. The front part 200A is located on the side of the second plate P2 and is screwed into a bore 206 of the part 200B. The Z20 axis constitutes a central longitudinal axis of the front part 200A. The part 200B is movable in translation along the axis Z20 relative to the frame 14 with a cylindrical external surface 201 of the part 200B guided in a cylindrical housing 142 of the frame 14. The front part 200A comprises a portion of reduced diameter 208, and a flared end 210. In the retracted position of the locking ring 202 relative to the locking shaft 200, the reduced diameter portion 208 is aligned with the internal outlets of the housings 202a, which allows the locking balls 22 d '' reach their retracted internal radial position, radially set back from the external radial surface 202d. When the locking ring 202 reaches its advanced position relative to the locking shaft 200 under the action of the spring 204, the flared end 210 pushes the locking balls 22 radially outward, with reference to the axis Z20, in their second external projecting radial position, in which they project radially from the external radial surface 202d of the locking ring 202. In the advanced position of the locking ring 202 relative to the locking shaft 200, the movement of the ring 202 forwards in the direction Z20 is stopped by the balls 22 which cooperate radially and axially with the flared end 210 of the locking shaft 200.
    In the uncoupled configuration of the plate P1, the rear shoulder 202c abuts against the first plate P1 and the locking ring 202 is held in its retracted position relative to the locking shaft 200, which is in the advanced position relative to to frame 14.
    In the retracted position of the locking ring 202 relative to the locking shaft 200, the locking balls 22 cooperate with the reduced diameter portion 208 of the screwed part 200A and can retract in the locking ring 202 so as not to plus protrude radially out of the locking ring 202. The diameter of the external radial surface 202d of the locking ring 202, at each housing 202a of the locking balls 22, is substantially equal, apart from the operating clearance, to inside diameter of the locking sleeve 12 in its constricted part 122. Thus when the locking balls 22 are in the unlocked position, retracted in the locking ring 202, the locking ring 202 and the locking shaft 200 can be partially introduced in the internal bore 120 of the locking sleeve 12.
    In the unlocked configuration of the locking device 6 and uncoupled from the plate P1, in which the connection elements 2 and 4 are uncoupled, the guide column 8 protrudes forward in the connection direction Z relative to the shaft of lock 200 which is in its advanced position relative to the frame 14, as can be seen in FIG. 2.
    In the example shown, the connection elements 2 and 4 are fluid connection elements. In the uncoupled configuration, a valve 2a of each connecting element 2 is in the closed position against a seat 2b with a seal 2b1 interposed between the valve 2a and the seat 2b, under the action of springs 2c. This configuration is shown in Figure 2. On the second plate P2, the connecting elements 4 also each include a valve 4a which is held in the sealed position in uncoupled configuration by a spring 4b.
    The drive mechanism 16 also comprises one or more elements for transforming the rotational movement of the rotating element 18 around the axis X18 into a translational movement of the sliding element 20 along the axis Z20. In the example shown, the rotating element 18 is integral in rotation about the axis X18 with a control finger 24 whose central longitudinal axis X24 extends parallel to the axis of rotation X18 and in an offset manner relative to this axis X18. The control finger 24 is housed in a housing 186 of the rotating element 18. A bearing ring 240 mounted around the control finger 24 and in a housing 187 of the rotating element 18 is engaged in a roller 242 sliding in a notch 207 of the part 200B of the locking shaft 200, transverse to the axis Z20, in a direction perpendicular to the plane formed by the axes Z20 and X18. As the locking shaft 200 is guided along the sliding axis Z20 by the housing 142, the movement of the control finger 24 around the axis X18 is transformed into an axial movement along the axis Z20 of the part 200B and causes the sliding element 20 to drive. Thus the position of the rotating element 18 in the frame 14 around the axis X18 conditions the position of the front part 200A and of the rear part 200B of the sliding element 20 in the frame 14 along the axis Z20.
    According to the invention, the locking device 6 also comprises a pawl 26. The pawl 26 is mounted movably in a housing of the frame 14 and pushed back by a spring 28 in the direction of one of several ratchet notches secured to a element of the drive mechanism 16 and juxtaposed in the direction of movement with respect to the frame 14 of the element of the drive mechanism 16 of which the click notches are integral. In a snap-on configuration, the pawl 26 is mounted movable relative to the frame 14 along a sliding axis Z26 while being integral with the frame 14 in a circumferential direction around the axis X18. In this example, the click notches are provided on the rotating element 18 which forms a ratchet wheel or a toothed wheel. The click notches are recessed from a cylindrical external radial surface 184 of the rotating element 18 and are therefore juxtaposed in a circumferential direction around the axis X18.
    The click notches include a final notch and at least one intermediate notch. More specifically, in the example shown, the click slots 301 to 309 are nine in number over an angular amplitude of 200 ° around the axis X18. In the latching configuration, the pawl 26 is engaged in one of the latching notches 301 to 309. The latching notches 301 to 308 are made with a flat bottom 331 to 338, and the depth of each latching notch 301 to 308, taken relative to the external radial surface 184 radially to the axis X18, is variable. The click notches are thus separated from each other by declivities forming abutment surfaces 324 each extending in a plane passing through the axis X18. The maximum radial depth pf1 of a notch 301 to 308 is at the level of the abutment surface 324 projecting from the bottom of the notch in question while the radial depth of the notch gradually decreases to the surface of stop 324 in adjacent hollow. The notch 301 can be omitted, the notch 302 forming the initial notch. The slots 303 to 308 form intermediate click slots. The ninth notch known as the final notch 309 is produced with a bottom 339 which extends circumferentially to the axis X18 and has a radial depth pf2, taken with respect to the external radial surface 184, radially to the axis X18, strictly greater than the maximum radial depth pf 1.
    The pawl 26 is mounted in a housing 326 of a plug 32 of the frame 14, screwed into a housing of the frame 14 so that the housing 326 of the plug 32 opens into the housing 140 and on the outside of the locking device 6. The sliding direction of the pawl 26 is preferably radial with respect to the axis of rotation X18 of the rotating element 18. The sliding axis Z26 of the pawl 26 is preferably parallel to the connection direction Z.
    The pawl 26 comprises a body 260 of revolution centered on the axis Z26 and provided with four housings 262 in portion of a sphere visible on the sections AA-AA of FIGS. 2 and 8 and regularly distributed around the axis Z26. Each of these housings 262 accommodates a guide ball 264, which projects radially out of an external radial surface 260a of the body 260. The guide balls 264 form pawns of the pawl 26 which cooperate with grooves 320 of the plug 32 which are provided in a longitudinal direction of the plug 32 parallel to the axis of the slide Z26. The grooves 320 are provided on the internal surface of the housing 326, itself centered on the sliding axis Z26.
    The spring 28 is engaged between the plug 32 and a shoulder 266 of the pawl 26 which carries the housings 262 so that, when the guide balls 264 are engaged in the longitudinal grooves 320, the pawl 26 is resiliently biased towards the axis X18, in contact with the rotating element 18 and the end 261 of the pawl 26 cooperates with the bottom 331-339 of one of the nine notches 301 to 309.
    The pawl 26 also includes a ring 268 which surrounds the body 260 and is integral with the body 260 in the direction of the sliding axis Z26. The ring 268 forms a visual marker, for example of a different color and / or texture from the body 260 which, depending on the position of the pawl 26 along its sliding axis Z26, is made partially visible from the outside of the locking device 6 or masked by the plug 32.
    The pawl 26 finally comprises a head 270 screwed onto the body 260 and which protrudes from the plug 32 outside the locking device 6 so as to be manipulated by an operator.
    The housing 326 of the plug 32 further forms four retaining notches 322 which extend in the same circumferential direction to the axis Z26. Each of the four retaining notches 322 extends between two adjacent longitudinal grooves 320. The retaining notches 322 are arranged around the axis Z26 at the end of the longitudinal grooves 320 situated opposite the latching notches 301 to 309. When the guide balls 264 cooperate with the retaining notches 322, the pawl 26 is in the holding position, that is to say maintained in an external radial position with reference to the axis X18, against the force of the spring 28 and in which the end 261 is retracted out of the housing 140, and is released from the catch notches 301 to 309, as shown in FIG. 8. In the position for holding the catch 26, each guide ball 264 cooperates with a surface 322a, visible in FIGS. 4 and 8, the retaining notch 322 in which it is engaged. This surface 322a of the retaining notch 322 is interposed along the axis Z26 between the guide balls 264 of the pawl 26 and the rotating element 18 with pawl notches 301-309 and prevents the pawl 26 from sliding along the axis Z26 in the direction of the click notches 301-309.
    The passage of the guide balls 264 from the longitudinal grooves 320 to the retaining notches 322 requires the operator to pull the head 270 of the pawl 26 along the sliding axis Z26 to overcome the force of the spring 28 and a rotation of 45 ° of the pawl 26 around the axis of encryption Z26, this rotation being indifferently exerted in one direction or the other since each longitudinal groove 320 opens circumferentially on two retaining notches 322. The passage of the guide balls 264 from the retaining notches 322 towards the longitudinal grooves 320 require the operator to rotate the pawl 26 by a 45 ° rotation around the sliding axis Z26, regardless of the direction of rotation. Thus, between the holding position of the pawl 26 and the position of the pawl 26 in the snap configuration, the pawl 26 has been rotated in the frame 14 around the sliding axis Z26. On the AA-AA section of the plug 32 and the pawl 26 in FIG. 8, the 45 ° offset between the guide balls 264 and the longitudinal grooves 320 is visible.
    The operation of the set of plates E is described below. In the uncoupled configuration of the first plate P1, the pawl 26 is in the latching configuration: the guide balls 264 are engaged in the longitudinal grooves 320 and the end 261 of the pawl 26 is engaged in the initial latching notch 302 ( figure 2). The pawl 26 is returned elastically in contact with the bottom 332 of the pawl notch 302 by the spring 28. The locking shaft 200 is in the advanced position relative to the frame 14 along the axis Z20. When it comes to coupling and locking the two plates P1 and P2 together, the first plate P1 is brought closer to the second plate P2 along the connection direction Z. The guide elements formed by the column 8 of the first plate P1 engage with the complementary guide elements formed by the sleeve 10 of the second plate P2 for guiding the approximation of the plates in the connection direction Z. The locking shaft 200 then engages in the sleeve locking pin 12 and, when the locking balls 22 reach the locking sleeve 12, the locking balls 22 disappear inside the locking ring 202 in the unlocked position under the action of the tightened portion 122, and thanks to the space offered by the reduced diameter portion 208 of the locking shaft 200 which is aligned with the internal outlets of the housings 202a in this configuration. The retraction of the locking balls 222 allows the engagement of the locking ring 202 and the locking balls 22 in the locking sleeve 12 in the internal bore 120, in particular at the level of the portion of tightened internal diameter 122 then of the internal bore 120 of enlarged internal diameter.
    The locking ring 202 comes into abutment against the locking sleeve 12 at the level of the front shoulder 202b (FIG. 3). From this configuration, the locking and reconciliation of the plates P1 and P2 can be initiated. A key 34 is put in place by the operator around the hexagonal projection 180 and rotates this hexagonal projection 180, and therefore the rotating element 18, in rotation around the axis X18. The rotating element 18 is rotated over an angular amplitude corresponding at least to the angular extent around the axis X18 of the catch notch 302 in which the end 261 of the catch 26 is engaged. The angular ranges of the click slots 301 to 308 are substantially identical. The click-in amplitude of the drive mechanism 16 corresponds to the range of movement of each element of the drive mechanism 16 so that the pawl 26 engages in the next notch. The click amplitude corresponds to a rotation of the rotary element 18 over the angular extent a of each click notch 301 to 308, ie a rotation of the rotary element 18 substantially equal to 30 ° or ben preferably between 20 ° and 40 °. This rotation according to the arrow R1 in FIG. 2 causes the movement of the locking shaft 200 towards its retracted position in the frame 14, according to the arrow T1 in FIG. 3. During this rotation movement according to the arrow R1, the ratchet 26 is held elastically in contact with the bottom 332 of the ratchet notch 302 by the spring 28 and therefore follows the geometry of the bottom 332 of the notch 302 in which it is engaged. Due to the variable radial depth of each of the click notches 301 to 308, the pawl 26 moves along the sliding axis Z26, opposite the axis X18 outwards, the guide balls 264 sliding in the longitudinal grooves 320 until the pawl 26 engages in the next pawl notch 303, which is the first intermediate pawl notch, and comes into contact with the bottom 333 of this next notch 303 by sliding the pawl 26 under the force of the spring 28. In this configuration, called the intermediate configuration, even if the operator releases the action of the actuation key 34, the reverse rotation movement of the rotating element 18 in the opposite direction to the arrow R1, and therefore the movement of the locking shaft 200 relative to the frame 14, in the opposite direction to the arrow T1, is limited by the abutment of the end 261 of the pawl 26 on the surface of bu tee 324 separating the click notch 303 from the previous initial click notch 302. Each stop surface 324 of the rotating member 18 is oriented opposite the direction of movement of the arrow R1. The pawl 26 forms an obstacle to the abutment surface 324 of the rotating element 18 in the rotational movement of the rotating element 18 in the direction opposite to the arrow R1. The pawl 26 limits the movement of the locking shaft 200 towards its advanced position to an intermediate position relative to the frame 14 between its advanced position of the uncoupled configuration and its retracted position of the coupled configuration. The intermediate position is different from the advanced position and the retracted position. The operator can continue the rotation of the key 34 in the direction of the arrow R1 or bring the key 34 back to its starting position using a ratchet key system, while the rotating element 18 retains its angular position and that the sliding element 20 retains its intermediate position, and once again drive the hexagonal projection 180 in rotation at least over an amplitude corresponding to the click amplitude, ie a rotation of approximately 30 ° of the rotating element 18, which allows the pawl 26 to engage in the next click notch 304.
    The crossing of successive click notches continues. In particular in FIG. 4, showing an intermediate coupling configuration, the reverse rotation movement of the rotating element 18 in the direction opposite to the arrow R1 is prevented by the abutment of the end 261 of the pawl 26 on the abutment surface 324 separating the catch notch 305, in which the catch 26 is engaged, from the preceding catch notch 304. During coupling, when the catch 26 slides in the housing 326 in the snap configuration , the guide balls 264 do not reach the level of the retaining notches 322 along the axis Z26. The holding position of the pawl 26 is therefore offset along the axis Z26 relative to the positions taken by the pawl 26 in the snap-on configuration.
    Then the pawl 26 reaches the final notch 309 and the rotating element 18 reaches an amplitude limitation stop not shown. When the pawl 26 is engaged in an intermediate notch 303-308 and the end 261 of the pawl 26 is in abutment on the abutment surface 324 projecting from the bottom 333-338 of the intermediate notch 303-308, the pawl 26 maintains the locking shaft 200 in an intermediate position and prevents the locking shaft from reaching its advanced position.
    From the uncoupled configuration to the coupled configuration in which the pawl 26 is engaged in the final notch 309, the rotary element 18 has undergone a rotation of 180 °, preferably from 160 ° to 200 "according to arrow R1 , which places the visual marker 182 at a position offset by 180 ° pa from its initial position, which allows the operator to view the end of travel of the locking device 6. The visual marker 182 is visible by the operator even when the key 34 is engaged on the hexagonal projection 180.
    In addition, when the pawl 26 cooperates with the initial notch 302 and during the movement of the pawl 26 in the intermediate click notches 303 to 308, the colored ring forming the visual marker 268 remains visible to the operator because it is only partially masked by the plug 32. In the coupled configuration of the plate P1, the pawl 26 is in the snap configuration engaged in the final notch 309 (FIG. 5) and in contact with the bottom 339. Due to the difference in depth between the depth radial pf2 of the final notch 309 and the maximum radial depth pf 1 of the notches 301 to 308, the end 261 of the pawl 26 is closer to the axis X18 and the colored ring 268 is completely masked by the plug 32. This indicates to the operator that the final notch 309 has been reached and that the coupled locked configuration is obtained.
    Between the uncoupled configuration and the coupled configuration, the rotating element 18 has driven the control finger 24 in rotation about the axis X18, the roller 242 in translation along the axis Z20 which has itself caused the sliding of the 'locking shaft 200 along the axis Z20 from its advanced position relative to the frame 14 (Figure 3) to its retracted position relative to the frame 14 (Figure 6). The locking shaft 200 then moves relative to the locking ring 202 which is resiliently pushed back to its advanced position. In the advanced position of the locking ring 202 relative to the locking shaft 200, the locking balls 22 cooperate with the flared end 210 and are pushed back into the locked position, projecting partially beyond the external radial surface 202d. The locking balls 22 are engaged in the internal bore 120 and then form an obstacle connecting the locking sleeve 12 and the screwed part 200A of the locking shaft 200 along the axis Z20. Indeed, the locking balls 22 resist a force away from the plates P1 and P2 and transmit to the locking sleeve 12 the movement of the locking shaft 200 towards its retracted position. Advantageously but optionally, the rotation of the rotary element 18 allowing engagement of the pawl 26 from the initial notch 302 in the first intermediate notch 303, adjacent to the initial notch 302, or in the second intermediate notch 304, adjacent to the first intermediate notch 303, moves the locking shaft 200 relative to the locking ring 202 in a relative position such that the locking balls 22 cooperate with the flared end 210 and protrude outwards from the locking ring 202 in the locked position to form an obstacle to the separation of the plates P1 and P2 with the constricted part 122 of the locking sleeve 12. Thus the locking balls 22 are kept in the locked position and the plates P1 and P2 can no longer be separated as soon as the coupling operation has been initiated and the pawl 26 has reached the first enco che intermediate 303 or the second intermediate notch 304. Preferably, during coupling, the locking balls 22 are in the locked position as soon as the pawl 26 has reached the first intermediate notch 303.
    The continued movement of the locking shaft 200 in the frame 14 during the rotation of the rotating element 18 for connection causes a movement of approximation of the two plates P1 and P2 because the locking shaft 200 is linked according to the axis Z20 to the locking sleeve 12 by the locking balls 22, and therefore to the second plate P2. The locking ring 202, pushed back by the spring 204 in the advanced position, follows the movement of the locking shaft 200 in the frame 14, the balls 22 remain maintained in the locked position. During the approximation of the plates P1 and P2, the connecting elements 2 come to cooperate with the complementary connecting elements 4 of the plate P2, the seal is taken between a connecting element 2 and a complementary connecting element 4, the valves 2a and 4a are pushed back allowing the connection and opening of the fluid lines connected to the connection elements 2 and 4. In the coupled configuration of the plates, the plates P1 and P2 are in a relative position in which the connection elements 2 are coupled to the elements of intermediate connection 4, with opening of the valves 2a and 4a and therefore a fluid communication in the connections R formed by the connection elements 2 and the complementary connection elements 4 coupled. The connecting elements 2 and 4 are in axial abutment against each other. In this configuration, the fluid flow takes place between the connection elements 2 and the connection elements 4 according to the arrows F1 or in the opposite direction depending on the application.
    The plate P1 reaches its coupled configuration when the pawl 26 is engaged in the final notch 309. In this coupled configuration, the locking shaft 200 is in the retracted position relative to the frame 14 and the pawl 26 limits the rotation of the 'rotating element 18, and therefore the movement of the locking shaft 200 relative to the frame 14, in the unlocking direction, by abutment of the end 261 of the pawl 26 against the abutment surface 324 separating the notch final 309 of the previous intermediate notch 308. The locking shaft 200 is held in its retracted position by the pawl 26. In other words, the pawl 26 maintains the sliding element 20 in a position relative to the frame 14 compatible with the coupling of the connections R and the flow of fluid between the connection elements 2 and the connection elements 4. The restoring forces of the valves 2a and 4a in the closed position exerted by the res spells 2c and 4b tend to distance the two plates P1 and P2 but cannot separate them since the pawl 26 maintains the angular position of the rotating element 18 as well as the retracted position of the locking shaft 200 relative to the frame 14 in preventing it from reaching an intermediate position or its advanced position.
    For disconnection, the operator must release the rotating element 18 for its angular displacement in the opposite direction of the arrow R1, and therefore place the pawl 26 in the holding position with the guide balls 264 in the holding notches 322. For this, it exerts on the head 270 of the pawl 26 a tensile force along the axis Z26 along the arrow F2 in Figure 8 against the force of the spring 28, until the guide balls 264 in abutment against the end of the longitudinal grooves 320, then it exerts a 45 ° rotation of the pawl 26 around the axis Z26. The guide balls 264 then engage in the retaining notches 322 and, when the pawl 26 is released by the operator, the guide balls 264 remain engaged in the retaining notches 322, in contact with the surfaces 322a of the notches holding 322 under the force of the return of the spring 28. The pawl 26 then retains its external radial position in FIG. 8 in which it is radially disengaged from all the pawl notches 301 to 309 of the rotating element 18, l end 261 no longer forming an obstacle to the abutment surfaces 324 of the rotating element and not opposing the rotation of the rotating element 18 around the axis X18 in the direction of disconnection, according to arrow R2. The ring 268 is again visible.
    The operator then engages the key 34 on the hexagonal projection 180 and drives the rotating element 18 in the direction of disconnection from the coupled configuration to the uncoupled configuration by a 180 ° rotation of the key 34 or by successive low amplitude rotations, of the order of 30 °.
    The repulsion efforts of the valves 2a and 4a participate in the movement of the plates P1 and P2 in the direction of separation. During the rotation of the rotating element 18 in the direction of disconnection, the locking shaft 200, driven by the control finger 24, is moved in the frame 14 to its advanced position. The plate P2 follows the movement of the locking shaft 200 along the axis Z20, which causes the plates P1 and P2 to move away, and the connection elements 2 are released from the complementary connection elements 4, the valves 2a and 4a closing tightly and interrupting the circulation of fluid.
    The removal of the plates P1 and P2 continues until the first plate P1 can no longer move away from the second plate P2 with the contacting of the rear shoulder 202c of the locking ring 200 against the plate P1. Then the further movement of the locking shaft 200 relative to the frame 14 towards its advanced position causes the relative displacement of the locking ring 202 and the locking shaft 200, the locking ring 202 adopting its retracted position in which the locking balls 22 can disappear in the locking ring 202 and in the reduced diameter portion 208. The rotating element 18 reaches an amplitude limitation stop not shown. The operator grasps handle 1 and moves plate P1 away from plate P2. Under the action of the constricted portion 122, the locking balls 22 retract into the locking ring 202 in the unlocked position and are released from the locking sleeve 12. At the same time, the guide elements 8 and 10 cease their cooperation and the two plates P1 and P2 are separated.
    To allow a new connection, the pawl 26 must be replaced by the operator in the snap configuration in engagement with the initial notch 302. For this the operator turns the pawl by 45 ° author of its sliding axis Z26 in order to free the guide balls 264 from the retaining notches 322 and engage the guide balls 264 in the longitudinal grooves 320. Under the action of the spring 28, the end 261 of the pawl 26 again comes into contact with the element rotating 18, in contact with the bottom 332 of the notch 302. The amplitude limitation stop of the rotating element 18 in the uncoupled configuration has in fact placed the initial notch 302 facing the housing 326 and at the end 261 of the ratchet 26.
    The P1 multi-connector plate according to the invention allows the following advantages. The locking device 6 with ratchet 26 requires only a small amplitude of successive rotations with a key 34, to arrive at the coupled configuration, despite the repulsion efforts of the valves 2a and 4a. This is particularly suitable for plates with limited access or for high repulsion forces since the force to be supplied can be released after each successive rotation, the rotation of the rotating element 18 in the direction of disconnection being prevented by the cooperation of the pawl. 26 with one of the abutment surfaces 324 delimiting the click notches. The click amplitude of the drive mechanism 16, and therefore the number of intermediate click notches on the maximum amplitude of movement of the rotating element 18 between the uncoupled configuration and the coupled configuration, can be adapted according to the type application.
    The pawl 26 which can be positioned and maintained in the holding position thanks to the pins 264 allows an ergonomic disconnection, since it is not necessary for the operator to keep the pawl 26 in the external radial holding position during the unlocking rotation of the rotating element 18. The use of pins in the form of balls 264 allows improved guiding of the movement of the pawl 26 in the longitudinal grooves 320 and towards or from the retaining notches 322.
    The pawl 26 movable radially with respect to the axis of rotation X18 makes the locking device 6 compact along the axis X18.
    The movable pawl 26 parallel to the direction of connection Z makes it possible to provide access to the head 270 of the pawl 26 in the same zone as the handle 1 for the positioning of the first plate P1 on the second plate P2, which is recommended in case of limited access to plates P1 and P2.
    The difference between the maximum depth of the notches 301 to 308 and the depth of the final notch 309 of the rotating element 18 makes it possible to visually mark the position of the pawl 26 in the coupled configuration of the plates P1 and P2.
    A second embodiment of the invention is shown in Figures 9 and 10. In this embodiment, the elements common to the first mode have the same references and operate in the same way. Only the differences compared to the first embodiment are detailed below. FIG. 9 illustrates three connection elements 2 intended to be connected to three complementary connection elements not shown and carried by the second plate to form the connections.
    In the embodiment of FIGS. 9 and 10, the locking device 6 comprises latching notches 311 to 318 formed not on the external surface of the rotating element 18, but on another element of the drive mechanism 16 formed by the sliding element 20. The click notches 311 to 318 are hollowed out on an external surface 212 of the locking shaft 200, precisely of the rear part 200B, which is planar, disposed on the side opposite to the element turning 18 relative to the axis Z20 and perpendicular to the plane formed by the axis Z20 and the axis X18. The click notches 311 to 318 are then juxtaposed in a rectilinear fashion along the sliding axis Z20 of the locking shaft 200, which is parallel to the connection direction Z. The click notches 311 to 318 are therefore secured to the movement in translation of the locking shaft 200. In the uncoupled configuration of the plate P1, the end 261 of the pawl 26 is engaged in the initial notch 311 and the locking shaft 200 is in the advanced position relative to the frame 14, as illustrated in FIG. 10. In the coupled configuration of the plate P1, the end 261 of the pawl 26 is engaged in the final notch 318 and the locking shaft 200 is in the retracted position relative to the frame 14. Between the uncoupled configuration and the coupled configuration of the plate P1, the rotary element 18 has undergone a rotation which caused the movement of the locking shaft 200 according to the arrow T1 of FIG. 10 .
    The translational movement of the sliding element 20 in the frame is guided by a cylindrical housing 142 which cooperates with two lateral surfaces 214 in the cylinder portion of the locking shaft 200.
    In this case, the pawl 26 slides in a housing 326 of the frame 14 along a sliding axis X26 parallel to the axis of rotation X18 of the rotating element 18 but is integral with the frame 14 along the sliding axis Z20 . The sliding axis X26 is transverse, in particular orthogonal, to the direction of movement of the element 20 of the drive mechanism 16, of which the click notches 311-318 are integral. The same device for cooperation between a surface of the frame 14 and the pawl 26 along the axis X26 to maintain the pawl 26 in the released holding position outside the pawl notches 311 to 318 when disconnected is provided. Each click notch 311 to 317 provided on the locking shaft 200 extends over a length, along the axis Z20, corresponding to the travel traveled by the locking shaft 200 relative to the frame 14 during a rotation of the rotary element 18 about the axis X18 of an amplitude corresponding to the click amplitude of the drive mechanism 16, or a rotation of approximately 30 ° of the rotary element 18 or, more generally, at an amplitude of movement of the key 34 corresponding to a rotation of 30 ° or alternatively at a rotation of between 20 ° and 40 ° of the rotating element 18. The rotation of the rotating element 18 over an amplitude corresponding to one click amplitude allows the pawl 26 to reach the next click notch 312-317 to the final notch 318.
    In the same way as in the first embodiment, each intermediate click-out notch 312-317 and end 318 is delimited by a respective bottom 352 to 357 and 358 and a stop surface 324 projecting from the bottom 352-358 of the click notch considered. Each abutment surface 324 extends perpendicular to the axis Z20 and is oriented opposite to the direction of movement of the arrow T1. When the pawl 26 cooperates with the abutment surface 324, the pawl 26 forms an obstacle to the locking shaft 200 in a movement in the direction of disconnection directed along the arrow T2 in FIG. 9, opposite to the arrow T1, and blocks the movement of the locking shaft 200 towards its advanced position and therefore the rotation of the rotating element 18 in the direction of disconnection.
    In the intermediate configuration, when the pawl 26 is engaged in an intermediate notch 312-317, the pawl 26 limits the movement of the sliding element 20 in the frame 14 to an intermediate position between its advanced position and its retracted position.
    In the coupled configuration, when the pawl 26 is engaged in the final notch 318, the pawl 26 limits the movement of the sliding element 20 towards its advanced position and maintains the locking shaft 200 in its retracted position. In other words, the pawl 26 maintains the sliding element 20 in a position relative to the frame 14 compatible with the coupling of the connections and the flow of fluid between the connection elements 2 and the complementary connection elements.
    Not shown, in the same way as in the first embodiment, the depth of the final notch 318, taken parallel to the axis X26 and relative to the external surface 212, can be greater than the depth of the notches initials and intermediaries 311 to 317 in order to allow masking of the visual marker 268 carried by the pawl 26 in the coupled and locked configuration.
    According to embodiments not shown:
    the pawl 26 can have a sliding sliding axis relative to the axis of rotation X18 of the rotating element 18, but not parallel to the connection direction Z. For example, the sliding axis of the pawling 26 can be orthogonal to the X18 axis and the Z direction.
    the pawl 26 may have a sliding axis parallel to the axis of rotation X18 of the rotating element 18, and the pawl notches be formed on an axial surface of the rotating element 18, that is to say on a surface perpendicular to the axis of rotation X18, and not a radial surface, that is to say surrounding the axis X18, as is the case in the first embodiment. The click notches are then juxtaposed in a circumferential direction around the axis of rotation of the rotating element 18.
    - The locking device does not have an initial click notch, the pawl 26 being in contact with the external surface 184 or 212 in the uncoupled configuration.
    the rotating element 18 can be fitted on an external radial surface with juxtaposed snap notches in a circumferential direction around the axis of rotation of the rotating element 18 and a pawl end mounted in a housing of the frame 14 with possibility of rotation relative to the frame 14 about an axis parallel to the axis of rotation X18 of the rotating element 18 is resiliently recalled in cooperation with one of the click notches. To place the pawl in the holding position, it is then necessary to exert a rotational force on the pawl which releases the end of the pawl out of the click notches.
    - The pin (s) 264 of the pawl 26 projecting from the external surface of the body 260 may have a shape other than the spherical geometry described, for example cylindrical. This or these pins can be integral with the body 260.- Pins can be formed projecting from the internal housing 326 of the plug 32 and cooperate with longitudinal grooves and retaining notches formed on the external radial surface of the body 260. When the pins cooperate with the body retaining notches 260, the pawl 26 is held in the holding position; when the pins cooperate with the longitudinal grooves of the body 260, the pawl 26 is pushed elastically into engagement in one of the pawl notches.
    the locking device 6 can be equipped with a locking shaft 200 parallel to the axis of rotation X18 of the rotating element 18, according to a principle similar to JPH 07 208 673. The elements for transforming the rotation movement of the rotary element 18 in translational movement of the sliding element 20 then comprises a roller and a cam profile.
    the locking device 6 can comprise locking members which are movable relative to the axis Z20 and cooperate with the locking shaft 200 while being housed in a housing passing through in the locking shaft 200 and the shaft locking 200 receives, in an internal reception volume, a locking pin of the second plate P2 provided with an external circumferential notch for receiving the locking members, according to a principle similar to US 8,864,179.
    - the plates P1 and P2 can carry electrical connection elements. The plates P1 and P2 can incorporate electrical connections, fluidic connections or combinations of fluidic and electrical connections. Several connection elements carried by the plate P1 are connected to the complementary connection elements by bringing the two plates P1 and P2 together.
    - The locking members can be other than balls, for example locking fingers, locking segments.
    the grip profile formed by the hexagonal projection 180 can be formed by a projection of another geometry, for example square or triangular, or by an imprint, for example of the hexagonal type, 6-pointed star, square, triangular, formed recessed in the rotating element and accessible from outside the frame 14.
    The characteristics of the embodiments and variants described above can be combined to form new embodiments of the invention.
