    专利说明:

    [0001] The invention relates to the field of electrical connections, for example electrical power connectors and, in particular, electrical power connectors for hybrid motor vehicles. Power electrical connectors are used in electric or hybrid motor vehicles for example to interconnect a battery pack to an electric motor, a power converter, etc.
    [0002] In hybrid vehicles, the heat engine generates vibrations that are transmitted to the power cables and thus also to the connectors and their contacts. The section of the power cables being relatively large (for example 40 or 50mm2), they are rigid and have a large inertia. The level of these vibrations can then reach 15G, 25G or 40G depending on the location of the cables and connectors. With such vibration levels, the points of electrical contact between the electrical contacts of the connectors can wear prematurely. This results in a risk of overheating or even fire. It is therefore important to prevent this risk. To this end, it is proposed a device for fixing and tightening cable, in particular for electrical connector, comprising a bushing, a clamping ring and locking means carried at least in part by the clamping ring, to block the displacement of the clamping ring relative to the sleeve. In this document, a bushing is essentially a hollow sleeve, with a substantially cylindrical inner wall ensuring the clamping and locking of one or more cables, and an outer wall also substantially cylindrical on which is placed a clamping ring. The socket may consist of one or more parts (for example two half-sockets). One and / or the other of these parts comprises (s) an inner surface corresponding to at least a substantially cylindrical portion (a half-cylinder for a half-socket, for example). The socket may be located for example on a connector or on any other device having one or more contacts to protect against vibration or upstream thereof. Many shapes and configurations of bushings or bush portions, as well as a variety of bushings can be envisaged. For example, one can have two complementary half-sleeves forming when tightened on the cable, a substantially cylindrical passage, with a circular periphery closed or almost. It can have a fixed bushing portion and a sleeve portion movable about an axis of rotation on which it is articulated. One can also have two half-sleeves mobile about the axis of rotation on which they are respectively articulated. One can also have several pairs of half-sockets, each pair respectively blocking a cable. Both the bushing and the clamping ring have an opening (i.e., a passageway) for the passage of a cable. The bushing and the clamping ring are both plastic parts, for example. At least one of the bushing and the clamping ring has an inner surface for pressing an outer surface of the cable or an insert thereon, such as, for example, a thermally insulating sheath portion. retractable. This inner surface thus comes into contact with the cable to lock the cable, when the clamping ring is moved relative to the sleeve, a position in which the clamping ring is disengaged from the sleeve and a displacement of the cable is possible to a position in which the cable is blocked. This inner surface may be located for example on a sleeve portion (eg half-sleeve) movable carried by a flange hinged about an axis of rotation. If the same flange carries one or more bushing portions, each movable bushing portion is then articulated on a flange about an axis of rotation, between a loosened position, in which the cable can be moved, and a tight position, in which sleeve portions are held tight on the cable by the clamping ring, when it is manipulated to tighten the cable in the clamping device. Not only, a movable sleeve portion is hinged to a flange, but furthermore it can be removably mounted on this flange. Thus, the assembly of voluminous contacts and a unitary wire seal is made possible, before mounting the socket portions and their respective flange. Each movable bushing portion then contributes to blocking the contact and the seal respectively in a cavity and a groove provided for this purpose. When the movable sleeve is in a tight position on the cable, the inner surface is spaced from the axis of rotation by a radius greater than the shortest distance between the axis of rotation and the outer surface of the cable. In other words, when the movable bushing portion is in the tightened position by the clamping ring, the internal diameter of the cable passage at the bushing is less than the outer diameter of the cable and its outer insulating sheath. This occurs by a tilting effect of the (or) socket portions movable around the axis of rotation which allows to partially release or block the passage of the cable. It is important to consider that the clamping device according to the invention has few elements and that the clamping ring is the element which is directly manipulated by an operator to be moved, with respect to the bushing, a position wherein the cable is not tightened and can still be moved through the passageway in the clamping ring and socket to a position where the cable is blocked and can no longer be easily moved through the passage. The locking means are carried at least in part by the clamping ring so as to be activated when tightening the clamping ring. The locking means have at least one non-return catch. Such a non-return notch makes it possible to block the displacement of the clamping ring with respect to the socket in a direction or a direction opposite to the clamping displacement of the ring with respect to the socket. Such locking means thus make it possible to prevent the ring from becoming loose, even when the fixing device is subjected to strong vibrations and this for long periods of time (which would not necessarily be the case with a screw device). ). The displacement of the clamping ring relative to the bushing is carried out initially by translation to tighten the sleeve on the cable, and then in a second time by rotation, to lock the clamping ring on the sleeve. This has a better ergonomics compared to a rotation of the ring on a thread of the socket. Indeed, in the case of a thread, several turns in rotation of the ring would be necessary to obtain sufficient translation to the movement of the sleeve on the cable. Such screwing of the ring on the socket can be tedious and can be difficult when the fastener is in a congested or confined environment.
    [0003] Thus, to achieve a displacement of the ring on the sleeve in translation parallel to the longitudinal axis of the cable, it is possible to press the clamping ring parallel to this axis. This can be done relatively easily even when the circular surroundings around the clamping ring are congested. Similarly, to achieve a clamping of the ring on the sleeve by rotation, it is possible to perform a rotation of the clamping ring on less than one turn. This makes it possible to provide particularly ergonomic cable clamping devices. The device according to the invention may comprise the following features, considered alone or in combination: it comprises a flange which carries at least two movable bushing portions and which is common to at least two cable passages; the locking means are complementary and respectively carried partly on the sleeve and partly on the clamping ring; the locking means comprise at least one tooth carried by one of the clamping ring and the sleeve and each engaging in a notch carried by the other of these elements; and the movement of the clamping ring relative to the bushing comprises a translation to insert the clamping ring on the bushing and a rotation to lock the clamping ring on the bushing.
    [0004] Other features of the invention are the subject of claims and / or appear on reading the detailed description which follows, as well as in the accompanying drawings. In these drawings: Figure 1 shows schematically in perspective an embodiment of a clamping device according to the invention; FIGS. 2A to 2G show, in a manner similar to FIG. 1, different steps of mounting and clamping the device of FIG. 1; Figures 3A to 3D show schematically in axial section, respectively the steps of insertion and clamping of the clamping ring on the sleeve of the device of Figure 1; Figures 4A and 4B show in detail, schematically and in perspective and partly in section, the clamping of the clamping ring on the sleeve of the clamping device of Figure 1; FIG. 5 diagrammatically shows the articulation of a movable bushing portion of a device or a connector according to the invention; and Figure 6 shows schematically in perspective an electrical connector according to the invention. The cable clamping device 1 shown in FIGS. 1, 2A to 2G, 3A to 3D, 4A and 4B is a device for a box 5 of electrical contacts, intended to be mounted on the carcass of an electrical power device, such as a converter. Simultaneously with the mounting of the support 5 on the power device, the contacts 19 (here male contacts) are connected to female contacts mounted for example on a busbar electric circuit. In the example illustrated, the clamping device comprises a housing 5 inside which three cavities 40 are formed (see also FIG. 3A to 3D). The housing 5 is at least partially surrounded by a metal shielding plate 41 adapted to achieve a continuity of shielding between a braid (not shown) surrounding the cables 4 and the carcass of an electrical power device (also not shown). The braid is held on the metal shield plate 41 by means of a collar (not shown).
    [0005] The housing 5 and the metal plate 41 of shielding can be mounted screwed on the carcass of the electric power device. As illustrated in FIG. 2A, each cavity 40 accommodates a contact 19 and a unitary wire seal 12. Before crimping each contact 19 on a cable 4, a clamping ring 3 and a seal 12 are threaded onto this cable 4. Each contact 19 is then placed in a cavity 40, then each seal 12 is pushed into a groove 42 located at the rear of each cavity 40 (see Figure 2B). Each cavity 40 is also extended at the rear by two flange portions 43. Each flange portion 43 extends circumferentially around each cable 4 over substantially a quarter circle. Each flange portion 43 has an opening 44. As illustrated in Figures 2C and 2D, a lower flange 45, joining three half-sleeves 50 in a single piece, is placed behind the three cavities 40. This lower flange 45 is placed under the cables 4 and is retained on the three lower flange portions 43 at least in part by three pins 46 each respectively inserted into an opening 44 (see also Figure 3A). Similarly, an upper flange 47, similar to the lower flange 45, is placed symmetrically above the cables 4 with respect to the lower flange 45 and is retained on the three upper flange portions 43 at least in part by virtue of three lugs 46. each respectively inserted into an opening 44 (Figures 2D and 3A). The lower and upper flanges 45 and 45 are articulated about rotation points R located substantially at the lugs 46 inserted into the openings 44. In other words, the lower flanges 45 and upper 47 are articulated each respectively about an axis of rotation passing through three of these rotation points R and are symmetrical to one another with respect to a plane passing substantially through the longitudinal axes of the cables 4. Once in place, each pair of half-bushings 50 opens. like a jaw. In this position half-sleeves 50, the cables 4 are not yet blocked and can be moved through the passage formed between them (see Figures 2D and 3A). Each element consisting of a flange 45, 47 and three half-sleeves 50 carried by it, has a shape of L in perpendicular section (plane of Figures 3A to 3D) at their axis of rotation and passing through the points of rotation R. One of the branches of this L corresponding to a half-sleeve 50 and the other of these branches corresponding to a flange 45 or 47 connecting the three half-sleeves 50 between them. The lugs 46 are located at the top of the free end of the limb of the flange 45, 47 (see in particular FIGS. 3A to 3D). When the half-sleeves 50 are brought towards each other, the respective flanges 45, 47 are aligned (FIGS. 2E to 2G, 3C and 3G). One of the advantages of having a single element consisting of a flange 45, 47 and several portions of bushings (here three half-bushings 50), common to several cables 4 (and possibly identical on both sides of cables 4) lies in the fact that it reduces the number of parts to manufacture, handle and mount. Each sleeve portion (here a half-sleeve 50) has an inner surface 34 corresponding to a cylinder portion (here substantially semicylindrical). The approximation of the sleeve portions towards one another makes it possible to form a complete socket 2 in the form of a hollow sleeve, one around each cable 4, with an essentially cylindrical inner wall 52 ensuring the tightening of a cable 4 and an outer wall 54 also substantially cylindrical on which is placed a clamping ring 3. According to variants, the bushing portions could correspond to smaller portions of a cylinder and longitudinal slots could be arranged in the bushing complete, between the socket portions. In other words, the bushing portions are not necessarily joined in the complete bushing. The bushing 2 and the clamping ring 3 each comprise an opening 26, 27 for the passage of a cable 4. Each clamping ring 3 can then be inserted into a socket (see FIGS. 2E, 2F, 3B and 3C). Each clamping ring 3 and each half-bushing 50 have bevelled surfaces 57, sliding one on the other to facilitate the insertion of each clamping ring 3 onto a bushing 2. When a clamping ring 3 is manipulated in translation longitudinally along a bush 2, towards a seal 12, it is moved relative to the bushing 2, a position in which the cable 4 can be moved to a position in which the cable 4 is blocked. Simultaneously, the half-bushings 50 and the flanges 45, 47 pivot about the axis of rotation, to get closer to each other. When a clamping ring 3 is in abutment on the lower flanges 45 and upper 47, the bushing 2 on which it is mounted is completely tightened on the cable 4 and the latter is blocked (see FIGS. 2F, 3C). As shown diagrammatically in FIG. 5, so that the cable 4 can be blocked during the rotation of the lower and upper flanges 45 around their axis of rotation, at least a portion of the inner surface 34 must be at a distance from the axis of rotation of a radius r greater than the distance d between the axis of rotation and the outer surface 58 of the cable 4. To increase the effectiveness of the locking, the inner surface of the sleeves comprises ribs 59 whose diameter internal, once the lower flanges 45 and 47 upper close together, is less than the outer diameter of the insulating sheath of the cable 4. To ensure that each clamping ring 3 will not escape from the sleeve 2 on which it is mounted, each clamping ring 3 is retained in rotation on a sleeve 2 by locking means. These locking means comprise ramps 21 on each bushing 2 and on each clamping ring 3 (see FIGS.4A and 4B), are arranged in a circular manner about the longitudinal axis L of the cables 4. By operating a rotation of a clamping ring 3 with respect to a bushing 2 of substantially less than a quarter of a turn (see displacement of the visual references 60 between their unlocked position in FIG. 2F and their locked position in FIGS. 1 and 2G), this latter is locked on this sleeve 2. As can be seen in Figure 4A, the clamping ring 3 is held in the unlocked position (or pre-locked) by a tooth 30 which cooperates with a notch 29 preceding a series of teeth 31 located on a ramp 21 and protruding on the inner surface of the clamping ring 3. As shown in Figures 3C and 3D, each sleeve 2 comprises a circular groove portion 61 adapted to receive a protruding pin 62 e on the inner surface of the clamping ring. In the unlocked position of the clamping ring 3, the pin 62 is not engaged in the circular groove portion 61, the clamping ring 3 can therefore be removed from the sleeve 2.
    [0006] In FIGS. 3D and 4B, after about one-quarter turn rotation of the clamping ring 3, the clamping ring 3 is held in the locked position. The pin 62 is now engaged in the circular groove portion 61 and the clamping ring 3 can no longer be removed from the bushing 2. The tooth 30 has slipped on the series of teeth 31 to fit in a notch 63. The teeth 30, 31 constitute locking means with non-return notches. The visual cue 60 is now located in front of an opening 44. FIG. 5 represents another embodiment of the invention. This is an electrical connector. It comprises a housing 5 and two contacts, each crimped on a cable 4. A fastening device 1 such as that described above, but with two bushings 2 and 2 clamping rings 3, instead of three) came from material (For example by molding) with the housing 5 to limit the vibration propogation of the cable 4 to the contacts.
