[0001] FIELD OF THE INVENTION The invention relates to a socket outlet, a current connector base and an assembly comprising a socket outlet and a current connector base.
[0002] STATE OF THE PRIOR ART There are known socket-outlets equipped with a safety disc to avoid any contact with the active parts (i.e. under tension) of the base when the latter is not connected with a connector base. However, the connection of such a socket base with a connector base has a complex and unintuitive kinematics, requiring the user two movements of large amplitude, including a rotational movement to rotate the security disk and a translation movement to effectively bring into contact the active parts (ie under tension) of the bases.
[0003] PRESENTATION OF THE INVENTION According to one embodiment, the socket base extends in an axial direction and comprises at least one housing configured to receive a pin of a current connector base, and a movable safety disc. in rotation between a protection position preventing access to said housing and a connection position allowing access to said housing, wherein the socket base comprises a device for rotating the security disk configured to cooperate with the connector base, the rotation device bringing the safety disk from the protection position to the connection position during relative axial movement between the socket base and the connector socket during the fitting of the connector socket with the socket base. Recall that a socket base forms a female part that can belong to a socket (where the socket is generally integral with a wall or the like), an extension, or a connector (where the socket socket usually a part of a mobile socket) while a connector socket forms a male part that may belong to a power outlet (or the connector socket is usually part of the mobile plug), an extension, or a connector (where the connector socket is usually attached to a device or equivalent).
[0004] It is also recalled that generally, a movable socket comprises a socket base and a handle or rollover integral with said socket base; a plug comprises a connector socket and a handle or cowling secured to said connector socket; an extender is an assembly comprising a movable plug and a plug; an outlet is an assembly comprising a socket base and a plug; a connector is an assembly comprising a mobile socket and a connector socket. Of course, the handle or cowling can be integrated (e) the socket base or the connector base, in which case said socket base or connector socket also forms a plug or plug.
[0005] It is understood that when the safety disk is in the protective position, it is not possible to introduce the pin (s) (ie electrical connection portion) of a connector base in the housing (s) ) of the socket base. Conversely, when the safety disc is in the connection position, the pin (s) can be inserted into the housing (s). For example, the security disk is rotatable about the axial direction, the disk being coaxial with the central axis (parallel to the axial direction) of the socket base. It should of course be understood that the security disc has a solid shape having a predetermined number of through-holes through which connector socket pins can pass, in particular when the disc is in the connection position and the holes are aligned with the housings. . The rotation device is configured to cooperate with a connector socket such that when the plug base is mated in the axial direction with the connector socket (or vice versa), the rotation device brings the security disc into position. connection. Thus, when the user moves axially the socket base to the connection base (or vice versa), thanks to the rotation device the disc is moved from the protective position to the connection position. The user therefore provides only a translational movement to rotate the security disk and can connect the socket base to a connector base. The kinematic connection is simplified compared to the socket of the state of the art. In certain embodiments, the rotation device 35 comprises a first element among a helical ramp (or first helical ramp) and a lug formed on an axial wall of the safety disc. It is understood that the safety disc has at least one axial wall, this axial wall having for example a cylindrical shape or a form of angular portion of a cylinder. According to a first variant, the axial wall has a helical ramp. For example, the helical ramp is formed by a wall of a helical groove formed in the axial wall. This helical ramp is configured to cooperate with a complementary element, for example a lug, which cooperates in axial support with the latter, whereby a rotational movement is impulsed to the safety disk. According to a second variant, the axial wall has a projecting lug. This lug is configured to cooperate with a complementary element, for example a helical ramp, which cooperates in axial support with the latter, whereby a rotational movement is impulsed to the safety disc. In some embodiments, the rotating device further comprises a drive ring of the disk, the second one of the helical ramp (or first helical ramp) and the lug being formed on an axial wall of the drive ring. , the second element being configured to cooperate with the first element. It is therefore understood that if the ramp is formed in an axial wall of the disc, then an axial wall of the drive ring vis-à-vis radially with the axial wall of the disc is equipped with a pin configured to cooperate with the helical ramp while if a lug is formed on the axial wall of the disc then it is the axial wall of the drive ring which is equipped with the helical ramp. Such a helical ramp / spigot system is a robust and reliable system for transforming a translational movement into a rotational movement.
[0006] In some embodiments, the drive ring is movable in translation, or only / strictly in translation, while the disk is movable in rotation, or only / strictly in rotation. When the drive ring is displaced in translation in the axial direction, in particular during the fitting of the connector base in the socket base, the cooperation between the pin and the helical groove transforms this translational movement into a movement of rotation, this rotational movement being communicated to the safety disc which then passes from the protective position to the connection position. Thus, the kinematics of each element is simplified and reduced to a minimum, which makes the socket base more reliable with respect to the socket bases of the state of the art. In some embodiments, the socket base comprises an internal body in which the housing is formed, said drive ring cooperating in axial sliding around the inner body while the safety disk is rotatably mounted on a distal end of said body. . The inner body forms the part of the socket base in which is formed the housing (s) receiving the pin (s) of the connector base. The safety disc is rotatably mounted on the inner body so as to seal or allow free access to (x) housing (s). The drive ring slides around the inner body when moved in translation. For example, the inner body has one or more guides extending in the axial direction and each receiving a projection extending radially from the ring, whereby it is ensured that the movement of the ring is strictly a translational movement. . Such a movement strictly in translation makes it possible to optimize the transformation of the translation movement into rotational movement. In some embodiments, a stop of the disc cooperates with the inner body and limits the rotational travel of the disc. By limiting the rotational stroke of the disc it is ensured that the latter is permanently in position to cooperate with the drive ring. This is particularly useful when the lug is not engaged in the helical groove, but the alignment of one relative to the other must be retained in anticipation of a new engagement of the one in the other. In some embodiments, the socket base includes a safety disk lock device in the protection position. Such a locking device makes it possible to ensure that it is not possible to pass the safety disk from the protection position to the connection position other than by making the socket base cooperate with the connector base. . Access to the active parts of the socket is therefore particularly limited, and increased security. In some embodiments, the locking device comprises a projection configured to engage with an axial groove, one of the projection and the axial groove being formed on the protective disk. It is therefore understood that if the protective disk, for example an axial wall of the protective disk, comprises a projection, then a complementary element belonging to the socket base comprises an axial groove receiving the projection and blocking the rotation of the disk when the disk is in the protective position while if the disk, for example an axial wall of the protection disk, comprises the axial groove, then a complementary element belonging to the socket base comprises a projection engaging with the groove to block the rotation of the disk when the disc is in the protection position. For example, an axially movable locking ring has such an axial groove or projection configured to engage or disengage respectively with the protrusion or groove formed on the disc. For example, in the case where the helical ramp (or first helical ramp) of the rotating device is formed by a side wall of a helical groove, the axial groove may be formed by an axial termination of said helical groove. Such a termination makes it possible to block the disk in rotation when the pin is engaged in this termination. Thus, the lug is used both in the rotation device, the lug cooperating with a side wall of the groove forming the helical ramp to rotate the disk, that in the disc locking device, the lug cooperating in the axial termination to block the rotating disk. In some embodiments, the socket base comprises a device for returning the disk bringing the disk back to the housing protection position. For example, the return device comprises one or more spring (s). For example, the return device comprises a torsion spring coaxially mounted with the safety disc, this spring bringing the disc for example when the pins do not cooperate with the disc during disconnection of the plug base and the connector base. In another example, the return device comprises one or more compression spring (s) which push the drive ring to a position where it keeps the disk in the protective position. Thus, when the ring is pressed via the connector base, the ring is moved in translation from an initial position to a final position which causes the disc from the protection position to the connection position, whereas when removes the connector base, the springs of the return device return the ring to the initial position, which causes the disc to the protection position. For example, if the first helical ramp of the rotating device is formed by a side wall of a helical groove, the side wall of the groove vis-à-vis the first ramp forms a second helical ramp which allows the pin to return the disc from the connection position to the protection position.
[0007] In some embodiments, the socket base includes a latch for locking the socket with the connector socket. Such a locking device is particularly advantageous for use of the socket base in an industrial environment. For example, such a locking device comprises an elastic hook configured to cooperate with a rib or a protrusion of the connector base. In addition, such a locking device makes it possible to hold together the socket base and the connector base, even in the presence of a device for returning the possible disk which would exert a force tending to eject the connector base from the socket base. In some embodiments, the socket base includes a retainer for retaining the connector socket at least partially fitted with said socket base. Such a retaining device makes it possible to prevent the connector base from being ejected from the socket base, for example when the socket base comprises a device for returning the disk. This retaining mechanism holds the connector base fitted with the socket base in a position such that the electrical connection between the active parts of the two bases is broken.
[0008] In some embodiments, the socket base includes an outer housing, said housing having an inner wall, the retainer includes a baffle rail formed on the inner wall. It is understood that the slide guides a slider secured to the connector base to accompany the fitting movement of the connector base with the socket while the slider blocks the withdrawal movement of the connector socket from the socket. of taking. For example, the slide is an axial slide forming an azimuth baffle. In this case, the baffle impels a rotational movement of the connector base when it fits with the socket base 10. Of course, this rotational movement is completely decoupled from the movement required to move the security disk. According to one variant, it is nevertheless possible to envisage combining these two movements. When removing the connector socket from the socket base, the azimuthal baffle blocks the connector socket. A rotation movement provided by the user then makes it possible to disengage the slider from the azimuthal baffle to totally disassemble the two pedestals. One embodiment relates to a current connector pedestal extending in an axial direction and including an axially extending central pin, said center pin including one of a helical ramp and a pin, said member forming an actuator for actuating a safety disc rotation device of a socket outlet. Such a connector base makes it possible to cooperate with a socket base 25 whose safety disk has a central hole configured to receive the central pin, the axial wall of the disk delimiting the central hole being equipped with the other element among the helical ramp. and the ergot. It will be appreciated that the center pin is generally, but not always, a grounding pin, such pin being known to those skilled in the art as the grounding pin or as the pin for the ground connection. earth contact. The center pin is usually distinct from the other pins (or peripheral pins) of the connector socket. One embodiment relates to an assembly comprising a receptacle base according to any one of the embodiments of the present disclosure and a current connector pedestal, the connector pedestal comprising an actuator for operating the disc rotation device. during a relative axial movement between the socket base and the connector socket during the fitting of the connector socket in the socket base.
[0009] In some embodiments, the actuator comprises an axially extending skirt, said skirt being configured to cooperate in abutment with the rotation device. For example, the skirt presses on the drive ring during the fitting of the connector base with the socket base, whereby the safety disk is rotated. BRIEF DESCRIPTION OF THE DRAWINGS The invention and its advantages will be better understood on reading the detailed description given below of various embodiments of the invention given as non-limiting examples. This description refers to the pages of appended figures, in which: - Figure 1 shows an assembly comprising a socket base and a connector socket according to a first embodiment, - Figure 2 shows the socket base of Figure 1 exploded perspective view, and - Figures 3A to 3F show the kinematics of the safety disc when fitting the connector base in the socket base, - Figure 4 shows an assembly comprising a socket and a base base connector according to a second embodiment, and - Figure 5 shows a sectional view of the safety disc of the second embodiment. DETAILED DESCRIPTION OF EMBODIMENTS FIG. 1 shows an assembly 100 comprising a socket base 10 and a connector socket 90. Note that in this FIG. 1, a cowling C is provided to be assembled to the connector socket 90, the cowling C and the connector base 90 thus forming assembled a plug. The gripping base 10 extends in an axial direction X and has a safety disc 12 and a disc drive ring 14 for bringing the safety disc 12 from a protective position to a connection position. The connector base 90 has a skirt 92 which extends axially in the X direction, said skirt 92 being configured to cooperate in abutment with the ring 14 during the fitting of the connector base 90 in the socket base 10. socket base 10 is now described in more detail with reference to FIG. 2. The socket base 10 comprises an outer casing 16, an inner body 18 mounted in the outer casing 16 and assembled to the latter by means of a 17. The disc 12 is rotatably mounted on the inner body 18 by means of a clip 19 projecting axially from the inner body 18. The disc 12 is disposed on the side of the end of the socket base 10 intended to be opposite the connector socket 90 when the socket base 10 is connected to the connector socket 90. In other words, the disc 12 is mounted on the distal end of the internal body 18. In general, and unless otherwise indicated In this presentation, the adjectives "inner / inner" and "outer / outer" are used with reference to a radial direction so that the inner portion (i.e. radially inner) of an element is closer to the X axis than the outer (i.e. radially outer) part of the same element. Thus, the inner side of a workpiece is the side facing or oriented towards the X axis while the outer side of a workpiece is the side facing in the opposite direction. A drive ring 14 is disposed around the inner body 18, cooperating in sliding in the axial direction X with the latter. Compression springs 22 are arranged between the inner body 18 and the drive ring 14.
[0010] The inner body 18 has in the axial direction X a base portion 18a and a connecting portion 18b forming a distal end portion of the inner body 18. The connecting portion 18b has a substantially cylindrical shape of X axis. 18a of the base forms a radial shoulder cooperating axially with outer housing 16 for mounting the inner body 18 within said housing 16. The inner body 18 has four housings 18c configured to each receive a pin 94 - also called peripheral pin 94 - ( see Fig. 1). A central housing 18d is configured to receive a central pin 95 (see fig.1). Spindle housings 18c and 18d extend axially.
[0011] The inner body 18 has two axial grooves 18e extending over substantially the entire axial length of the connecting portion 18b. These grooves 18e are open radially outwardly of the body 18, and open axially (ie axially open outlets) so as to receive each axially sliding a lug 14a of the ring 14, these lugs 14a extending radially inward of the ring 14. Each lug 14a can thus penetrate or emerge axially from a groove 18e on the side of the distal end of the inner body 18. The inner body 18 also has axial guides 18f extending over substantially the entire axial length of the connecting portion 18b each housing a spring 22. These guides 18f are open radially outward and each receive a projection 14b of the ring 14, these projections 14b extending radially inwardly of the ring 14. In this case, for example, the body 18 has four guides 18f while the ring 14 has four radial projections 14b evenly distributed azimuth (only two projections 14b are visible in Figure 2) . Each guide 18f / projection 14b is therefore spaced (e) approximately 45 ° from the guide 18f / projection 14b adjacent. The inner body 18 has an azimuthal groove 18g opening axially on the distal end face of the inner body. This groove 18g receives a stop 13 of the disk 12. The azimuthal groove 18g extends angularly about 55 °. The disc 12 has axial through holes 12a, in this example four holes 12a, configured to be simultaneously vis-à-vis the holes of the housing 18c. An axial through-center hole 12b is configured to cooperate with the snap-fastening staple 19 while permitting rotations about the X-axis of the disc 12. Thus, the staple 19 forms a pivot shaft for the disc 12. disk 12 is thus locked in translation by the clip 19, the disc 12 is thus movable only in rotation around the clip 19. The central housing 18d is concentric with the clip 19, this central housing 18d therefore not being In this example, the disc 12 pivots on itself about the axis X. The rotational travel of the disc 12 is limited by the stop 13 housed in the azimuthal groove 18g against the walls of which the stop 13 cooperates in abutment in the azimuthal direction. The maximum azimuth travel of the disc 12 is in this example 55 °. The disc 12 is rotatable between a stable position in which the holes 12a are not aligned with the housings 18c, the disk thus preventing access to the housing 18c, this position being a protective position, and a position in which the holes 12a are aligned with the housing 18c, the disk thus allowing access to the housing 18c, this position being a connection position. The axial outer peripheral wall of the disk 12 has two helical grooves 12c (a single groove being visible in FIG. 2), each groove receiving a lug 14a of the ring 14. The lateral wall 12c1 disposed on the side of the body 18 forms a helical ramp (or first helical ramp). Each helical groove 12c is open (or open) axially on the disc side opposite the body 18. Each groove 12c has an axial end 12d on the side of the disc opposite the body 18. Each axial end 12d forms an axial groove. Each end 12d is closed axially on the side intended to be arranged opposite the connector base 90. Thus, the lugs 14a can slide axially out of the helical grooves 12c on the side of the internal body 18, but are blocked in the termination 12d on the opposite side. In the connection position, the helical grooves 12c of the protective disc 12 open into the axial grooves 18e of the inner body 18. Thus the lugs 14a can slide continuously from the helical grooves 12c to the axial grooves 18e, and vice versa. This alignment is provided on the one hand thanks to the stop 13 and on the other hand thanks to the pins 94 engaged in the holes 12a when the bases 10 and 90 are connected. The internal radial projections 14b of the ring 14 being permanently engaged in the guides 18f, the rotational movements of the ring 14 are blocked. Thus, the ring 14 is slidably movable around the body 18 in a strictly axial movement. Each projection 14b is supported on one end of a spring 22 while the opposite end of said spring 22 bears on the body 18. Thus, the springs 22 tend to bring the ring 14 towards the distal end of the base of taken 10, and thus to bring the lugs 14a in the terminations 12d, whereby the springs 22 tend to bring and maintain the disk 12 in the protective position. It is of course understood that when the ring 12 is moved axially, the latter being locked in rotation, the lugs 14a drive the disk 12 in rotation cooperating with the helical grooves 12c.
[0012] The kinematics of the disk 12 and the ring 14 is now described with reference to FIGS. 3A to 3F. In these figures 3A, 3C and 3E the elements belonging to the socket base 10 are shown in solid lines while the elements belonging to the connector base 90 are shown in broken lines. FIGS. 3B, 3D and 3F respectively correspond to a view along arrow A of FIGS. 3A, 3C and 3E. Figures 3B, 3D and 3F, show only the ring 14 (solid line), the disc 12 and the body 18, the holes 12a of the disc being shown in continuous lines while the housing 18c of the body 18 are in broken lines. Note that in Figures 3A, 3C and 3D only three out of four pins 94 are visible. In FIG. 3A the skirt 92 of the connector base 90 is approaching the socket base 10. The skirt 92 bears axially against the ring 14, but no axial displacement has yet been achieved. The skirt 92 thus forms an actuator for actuating the ring 14. The safety disc 12 is in the protective position: the holes 12a of the disc 12 are not aligned with the housings 18c (see FIG. 3B). In this example, in the protective position, the lug 14a is positioned in the terminal 12d. Thus, thanks to the shape of the axial groove of the terminal 12d and its azimuth abutment cooperation with the lug 14a, even if one seeks to manually drive the protective disk 12 in rotation, this rotation is blocked. In this example, when the lug 14a is engaged in the terminal 12d, the assembly forms a locking device of the safety disc 12 in the safety position. Thus, when the lug 14a is engaged in the terminal 12d it is impossible to move the protective disk 12 from its protective position without the aid of the skirt 92. Note that in this example the housing 18d is permanently accessible this housing is reserved for the electrical connection to the ground, which of course does not present any risk in case of untimely contact. Note that in this position, the abutment 13 abuts in a first azimuthal direction with a radial wall of the azimuthal groove 18g, which reinforces the locking of the disc 12 in the first azimuthal direction. In FIG. 3C, the skirt 92 has been moved axially towards the socket base 10, which has cleared the pin 14a of the terminal 12d and engaged the latter in the helicoidal portion of the helical groove 12c, which has led to the disc 12 rotating about the axis X. Thus, in Figures 3C and 3D, the disk is in the intermediate position between the protective position and the connection position. The radial projections 14b (not shown in FIG. 3D) thus compress the springs 22.
[0013] In FIG. 3E, the skirt 92 has been further moved axially towards the socket base 10, which has brought the disc 12 into the connection position, thus allowing the pins 94 to penetrate into the housings 18c. Thus, in Figure 3E, the pins 94 are engaged in the holes 12a, and begin to enter the housings 18c. The helical groove 12c opening into the axial groove 18e of the body 18, the lug 14a continues its course in the axial groove 18e. As shown in FIG. 3F, the holes 12a are aligned with the housings 18c, the disc 12 being in the connection position. Note that in this position, the abutment 13 abuts in a second azimuthal direction, opposite the first azimuthal direction, with a radial wall of the azimuthal groove 18g, which blocks the rotation of the disk 12 in the second azimuthal direction. It is therefore understood that in this first embodiment, the helical ramp 12c1, the lug 14 and the drive ring 14 form a device for rotating the disk 12, while the skirt forms an actuator of the rotation device. To finalize the connection of the socket base 10 with the connector base 90, the axial fitting of the skirt 92 is continued until the radial tab 96 of the connector base 90 (see FIG. with the hook 20 of the socket base 10, this hook 20 forming a locking device. When the hook 20 cooperates with the tab 96, the socket base 10 and the connector socket 90 are held together. To remove the connector base 90 from the socket base 10, the tab 20a of the hook 20 is pressed, whereby the tab 96 is released and the springs 22 axially push the ring 14 towards the distal end of the socket base 10 Thus, the connector base 90 is pushed axially from the socket base 10 through the skirt 92. The springs 22 pushing the ring 14 axially, the pin 14a passes from the axial groove 18e in the helical groove 12c to in the termination 12d, which has the effect of bringing the disc 12 from the connection position to the protective position, the lug 14a cooperating with the springs 22 resting with the wall 12c2 of the helical groove 12c disposed on the opposite side to the body 18 and vis-à-vis the wall 12c1, this wall 12c2 forming a helical ramp (or second helical ramp). Thus, the springs 22 form a return device which generates movements transmitted between the ring 14, the lug 14a and the helical ramp 12c2 and for bringing the disk 12 back into the protective position. In order to hold the connector base 90 partially fitted in the socket base 10, for example when the tab 96 of the hook 20 is released and the springs 22 eject the connector base 90, the inner wall 16a of the outer casing 16 has two axial rails 24 forming baffle (a single slide being visible in Figure 2), each slide 24 forming a retaining device. In this example, each slide 24 is formed by a groove formed in the thickness of the wall 16a. According to one variant, the slideway is formed by a rail. Of course, the retaining device is optional and some variants do not have a retaining device. The radial walls 23 facing each other in the azimuthal direction delimiting each slideway 24 have, on the one hand, a ramp 23a and, on the other hand, an axial shoulder 23b, the ramp 23a and the shoulder 23b being disposed substantially opposite the from one another in the axial direction, thus forming a baffle. The skirt 92 of the connector base 90 has two sliders 98 protruding radially from the skirt 92, towards the outside of the skirt 92. When the skirt 92 penetrates axially into the socket base 10, each slider 98 slides on a ramp 23a. whereby the skirt 92 pivots around the X axis. During this movement, the sliders 98 engage behind the shoulders 23b. Note that in this example, the rotational movement driven by the retaining device on the connector base 90 does not affect the rotation of the disc 12. Moreover, this rotational movement of the connector base has an angular amplitude. reduced, in this example of the order of 10 °, and has almost no impact on the movement provided by the user for the connection of the connector base 90 on the socket base 10. The user feels almost no movement of rotation. When it is desired to remove the connector base 90 from the socket base 10, the sliders 98 cooperate axially abutting against the shoulders 23b, which has the effect of holding the connector base 90 partially fitted with the socket base 10 To fully disengage the connector socket 90 from the socket base 10, the user must clear the sliders 98 from the shoulders by pivoting the connector socket 90. Again, this rotational movement has no impact on the disc 12 Thus the movements vis-à-vis the retaining device and vis-à-vis the protective disk are fully decoupled.
[0014] In this example, for the connection the user needs to provide only one axial translation movement by introducing the skirt 92 of the connector base 90 into the socket base 10. To disconnect the two bases, the user must provide a low amplitude rotational movement, and a translational movement to remove the connector base 90 from the socket base 10. An assembly 200, including a socket base 110 and a connector socket 190, according to a second embodiment of FIG. embodiment is now described with reference to Figures 4 and 5. The socket base 110 differs from the socket base 10 according to the first embodiment mainly by the safety disc 112 and the ring 114 which in this example is not a ring drive but a locking ring of the safety disc 112 in the protective position. The connector base 190 differs from the connector base 90 according to the first embodiment mainly by the central pin 195, which in this example is equipped with a groove having a helical groove portion. Elements of the second embodiment similar to those of the first embodiment are not described again and only see their reference sign incremented by 100.
[0015] As shown in FIG. 5, the security disc 112 has an axially extending clip 119, through which the disc 112 is mounted on the inner body 118. The security disc 112 has a central hole 112b which extends through the clip 119, this hole 112b being configured to receive the central pin 195 of the connector base 190. The wall of this central hole forms an inner axial wall of the safety disc 112, two lugs 112c projecting radially towards inside from this axial wall. In addition the disc 112 has on its axial outer wall two axial grooves 112d. Each of these axial grooves 112d receives, when the disk 112 is in the safety position a radial projection 114a of the locking ring 114. The axial groove 112d and the projection 114a forms a locking device in the protective position of the disk 112. locking ring 114 is held in the locking position with the radial projections 114a engaged in the axial grooves 12d thanks to the compression springs 122 (a single spring 122 being shown in FIG. 5), which each cooperate with a not shown projection (similar at the projection 14b of the first embodiment) of the locking ring 114. The central pin 195 has on its axial wall two diametrically opposed helical grooves 195a (a single groove being visible in FIG. 5), the lateral wall 195a1 disposed of next to the proximal end of the pin 195 of each groove 195 forming a helical ramp 195a1 (or first helical ramp). Two portions of axial grooves 195b and 195c offset azimuthally relative to each other extend in the axial extension of the azimuthal groove 195a. These axial grooves thus form axial guides for the lug 112c.
[0016] All the groove portions 195a, 195b and 195c form a single groove opening axially. Of course according to one variant, the groove opening out axially comprises only one, two or more groove portions. When the plug base 110 is connected to the connector base 190, the pins 112c penetrate the axial grooves 195b (opening axially in the vicinity of the distal end of the central pin 195), while the skirt 192 presses on the locking ring 114, whereby the radial projections 114a are disengaged from the axial grooves 112d, thereby allowing the security disk 112 to be pivotable from its protective position.
[0017] When the projections 114a are completely disengaged from the grooves 112d, and the bases are continued to fit, each lug 112c penetrates into a helical groove 195a. In this helical groove 195a, the lug 114a cooperates in support with the ramp 195a1 whereby the safety disk 112 is rotated and passes from the protective position to the connection position. Of course, to be able to drive the disk 112 without the latter interfering with the peripheral pins 194, the central pin 195 has an axial length greater than that of the peripheral pins 194.
[0018] It is thus clear that in this second embodiment, the lug 112c forms a device for rotating the disk 112 while the helical ramp 195a1 forms an actuator of the rotation device. When the disc 112 is in the protective position, each lug 112c engages in an axial groove 195c, whereby the disc 15 is held in connection position while allowing to continue the fitting of the two bases and finalize the connection electric. During the disconnection of the two bases, the reverse movements take place, whereby each pin 112c cooperates with the helical ramp 195a2 (or second helical ramp) formed by the side wall of the helical groove 195a disposed on the end side. distal of the pin 195 vis-à-vis the helical ramp 195a1, and brings the security disc 112 from the connection position to the protective position. It will be noted that the springs 122 exert a stress on the locking ring 114a which cooperates in abutment with the skirt 192, which tends to eject the connector base 190 from the plug base 110, this ejection movement making it possible to transit automatically the pins 112c in the helical groove 195a. Thus, the springs 122 form a return device which generates movements transmitted between the ring 114, the skirt 192, the helical ramp 195a2 and the pin 112c for bringing the disk 112 back into the protective position. Although the present invention has been described with reference to specific exemplary embodiments, it is obvious that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. . In particular, individual features of the various embodiments illustrated / mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.5
