    ELBOW MULTICONTACT CONNECTOR AND METHOD
    ASSEMBLY
    The present invention relates to an angled electrical connector of the multi-contact type intended to be mounted on a cable comprising a plurality of insulated conductors, as well as a connection assembly comprising such a connector and an associated assembly method.
    The connector according to the invention is advantageously an RF connector, that is to say capable of transmitting signals of the range of DC (DC) to radio frequencies (RF), including microwave (HF), the signals being High Speed Data Link (HSDL) or RF signals. More specifically, the invention relates to angled multi-contact connectors for mounting on differential-pair type insulated conductor cables having four or more differential-pair conductors.
    EP 1825575B1 discloses an angled multi-contact connector, comprising an electrical insulator in which four central contacts are each mounted by snapping into a groove of the body, the snap-fastening being formed by the lateral side of the groove open on the outside on full length. This ratcheting solution is not satisfactory because in case of poor snap of one or the other of the contacts, it may occur a short circuit with the shielding conductive body arranged around the insulation.
    To avoid this short-circuit problem, the patent application EP 2915218A1 proposes to add tabs of material incorporated in the insulator, and which are folded by folding on the grooves once the contacts are snapped inside. . A disadvantage of this solution is that it is not easy for an operator performing the assembly of the connector to simultaneously hold the tabs in their folded position time to set up the shielding conductive body around.
    The patent application EP 2603953A1 proposes a similar solution of folding parts but which are mounted on hinges directly on the insulator, and which are folded to trap the contacts, block them but also isolate them with respect to each other, the portions before contacts are previously inserted longitudinally by the rear end of the body into through openings forming housing. This solution involves a significant additional cost related to the realization of the hinges, which can also be relatively fragile.
    The solutions disclosed by applications EP 2915218A1 and EP 2603953A1 also imply a choice of insulating material necessarily limited to the production of foldable tongues or hinged folding parts and a significant cost of implementation.
    There is a need to remedy some or all of the above disadvantages. The invention aims to meet this need and it achieves, in one of its aspects, with a multi-contact angled cable connector having a plurality of insulated conductors, comprising: - at least two bent contacts and adapted to be each fixed, preferably by crimping, by its rear end at one end of a cable conductor, - an insulating elbow made of insulating material, comprising: a front portion extending along a first axis of the insulator having at least two through openings, the through openings being adapted to each accommodate a front end of a contact, the front portion having at least one wall between through openings adapted to separate the contacts from each other; A rear portion extending along a second axis of the body; - An elbow body of conductive material comprising a front portion extending along a first axis of the body and having a through opening adapted to accommodate the front portion of the insulator and a rear portion extending along a second axis of the body and comprising a groove adapted to receive the rear portion of the insulation; - A cover of conductive material of complementary shape to the rear portion of the body, adapted to be fixed to the cable and close the conductive body around the contacts.
    The connector according to the invention is characterized in that the front portion of the insulator comprises at least one groove open towards the inside of the insulating body, the groove being adapted to receive at least partly a rear end of a contact. ; and in that it further comprises a piece of insulating material adapted to be attached to the insulator removably, the part having walls adapted to hold each rear end of a contact not received in the bottom of a groove of the insulator, and to separate on the one hand each rear end of another contact received or not in the bottom of a groove of the insulator, and secondly the conductive cover in its position of closing of the conductive body.
    According to an advantageous embodiment, the rear portion of the insulation is configured so that the insulating part comes to be inserted in a direction transverse to the second axis of the body, the insulating part having latching means on the rear portion a times the transverse insertion performed.
    In other words, the invention essentially consists in configuring the insulator to allow rearward insertion of the contacts and to allow the removable attachment of a single insulating part whose function is both to maintain, it is to block the contacts transversely to the axis of the rear portion of the insulation, to isolate the contacts from each other, and also to isolate the contacts which are the outermost of the connector elbow or the longest contacts, the conductive cover which forms with the conductive body a shielding assembly.
    The insulating part according to the invention has many advantages over the solutions according to the state of the art and in particular pliable tongues according to EP2915218A1 or foldable parts mounted on hinges according to EP2603953A1, among which: - no specific constraint for the choice the material constituting the insulating part; the cost of producing this insulating piece whose shape can be simple can be low; the assembly of this insulating part is reliable and easy; - The combination of the bent and grooved insulation with the insulating part allows the insulation of each contact with respect to another and the insulation between the body and the conductive cover and the contacts.
    According to an advantageous embodiment of the invention, the rear portion of the insulation is configured so that the insulating part comes to be inserted in a direction transverse to the second axis (Y) of the body, the insulating part having means for snap on the rear portion, once the transverse insertion performed.
    According to a first variant, the insulating part has a generally U-shaped shape, one of the branches of the U being adapted to make the separation between each rear end of the contact or contacts received in the bottom of a groove of the rear portion of the insulation and the one or more superposed contacts not received in the bottom of the groove, the other of the legs of the U being adapted to separate the conductive cover and each rear end of the contact or not received in the bottom of the groove, while the bottom of the U defines the mounting clearance of each rear end of the contact or not received in the bottom of the groove.
    According to another variant, the insulating part has a general shape in multiple U, one of the outer branches and the internal branch or branches of the multiple U being adapted to make the separation between each rear end of the contact or contacts received in the bottom. a groove of the rear portion of the insulator and that of the one or more superposed contacts not received in the bottom of the groove, the other of the outer branches of the multiple U being adapted to separate the conductive cover and each rear end or the contacts not received in the bottom of the groove, while the bottom of the multiple U defines the mounting clearance of each rear end of the contact or not received in the bottom of the groove.
    Preferably, the insulating part comprises at least one polarizer to avoid an error in the mounting direction.
    Advantageously, the connector comprises a conductive element closed on itself, adapted to be fixed inside the front portion of the conductive body so as to form a ground contact.
    According to an alternative embodiment, the connector comprises at least four elbow contacts, the front portion of the insulator comprising at least one wall for separating the two contacts housed in the openings inside the elbow of those housed in the openings to the outside the elbow or in openings made in intermediate positions of the elbow, the front portion and / or the rear portion of the insulation having at least one wall for separating the two contacts housed in the openings on one side of the first axis (X) insulation of those housed in openings on the other side or in intermediate openings.
    The conductive cover which closes the body is advantageously metallic. The configuration of the body and the hood makes it possible to limit high frequency leakage and to reinforce the mechanical maintenance of the connector insulation in the body.
    The body and the cover may be two separate parts, preferably metal, connected or not by a pivot hinge. The invention relates in another of its aspects to a connection assembly comprising: - a multi-contact angled connector as described above; an electrical insulating casing adapted to be mounted around the front portion of the elbow insulation. The invention further relates to a method of assembling a multi-contact angled connector portion, comprising the steps of: a / providing a cable with a plurality of insulated conductors; b / providing a portion of an angled connector intended to be mounted on said cable, the part of the connector comprising: - at least two contacts, - an insulating elbow made of insulating material, comprising: • a front portion extending according to a first axis of the insulator comprising at least two through openings, the through openings being adapted to each accommodate the front end of a contact, the front portion having at least one wall between through openings adapted to separate the contacts from each other; • a rear portion extending along a second axis of the insulator and having at least one groove open towards the outside of the insulator, the groove being adapted to receive at least partly the rear end of a contact; c) fixing the conductors of the cable with the contacts of the connector; d / insert parallel to the first axis of the elbow insulation the front ends of the contacts in the through openings of the front portion of the elbow insulation; e / bend the contacts, f / house the rear ends of the contacts located inside the bend in the grooves of the front portion of the insulation; g / snap a piece of insulating material in the rear portion of the insulation, the part having walls adapted to hold each rear end of a non-received contact in a groove of the insulator, and to separate on the one hand of each rear end of another contact received in a groove of the insulator, and secondly of the outside of the insulator, step c / being carried out either before step d / or after step f; step e / being performed either before step d / or after step d /.
    In a first variant of step c / of the method, the contacts can be crimped on the conductors of the cable. In this first variant, this step c / can occur before the step d / of partial insertion of the contacts in the insulator and the step e / of bending.
    In a second variant of step c /, the contacts may be soldered to the conductors of the cable. In this second variant, this step c / can occur before the step d / partial insertion of the contacts in the insulation and the step e / bending, or after step f / when the contacts are housed in the back part of the insulation.
    The contacts can be bent before or after their partial insertion in the front portion of the insulation. This variant can be applied to contacts already welded or crimped to the conductors of the cable. The method may advantageously comprise a step of crimping the cover on the rear portion of the conductive body. Π may also include an advantageous step of crimping the cover on at least one shielding braid and an inner and / or outer insulating sheath of the cable.
    The method according to the invention can be particularly simple and quick to implement, because the mounting of the contacts is done from behind by the housing of their front end in the openings through the insulation and, the establishment of the single piece ensuring the physical separation between contacts and with the outside and thus the conductive shielding cover, is done by a snap-in insertion into the insulation. The invention will be better understood on reading the following description of nonlimiting examples of implementation thereof and on examining the appended drawing in which: FIG. 1 is an exploded view of a connection assembly with a multi-contact angled connector according to the invention, Figures 2 and 2A are views respectively in perspective and along one of the axes of the bent insulation of a multi-contact bent connector according to an example of FIGS. 3, 3A and 3B are perspective views according to different angles of observation of the insulating part according to the invention, fixed from the bent insulation according to FIGS. 2 and 2A, the FIGS. 4A to 4L illustrate an example of the sequence of the different assembly steps of a connection assembly incorporating a multi-contact angled connector according to the invention; FIG. 5 is a perspective view of the connection assembly assembled according to the method illustrated in FIGS. 4A to 4L; Figure 6 is a side view showing a variant of the insulating part according to the invention as it is snapped into the insulation of the bent connector; Figure 7 is a cross-sectional view showing a variant of the insulating part according to the invention as it is snapped into the insulation of the bent connector; - Figures 8 to 8B show a perspective view of a variant of the invention for a number of eight superimposed contacts in two rows of four, respectively in the mounted position of the contacts in the insulator, in the latched position of the insulating part according to the invention in the insulation, and finally with the contacts mounted in the insulator, held by the insulating part, and crimped to the cable conductors; FIGS. 9 to 9B show a perspective view of a variant of the invention for a number of eight superimposed contacts in four rows of two, respectively in the mounted position of the contacts in the insulator, in the latched position of the insulating part conforming to the invention in the insulation, and finally with the contacts mounted in the insulator, held by the insulating part, and crimped to the cable conductors.
    FIG. 1 shows a connection assembly incorporating an angled multi-contact connector 1, according to an exemplary implementation of the invention.
    This assembly comprises in the example described, an angled connector 1 according to the invention, and a plastic housing 3 on which it is mounted.
    As illustrated, the bent connector 1 according to the invention comprises an assembly 4 comprising a number equal to four contacts 4.1, 4.2, 4.3, 4.4, an insulator 5 housing the contacts, a piece of insulating material 9 inserted and fixed by snapping into the insulator 5, a bent body of conductive material 6 housing the insulator 5 and the removable insulating part 9, a ground contact 7 closed on itself fixed to the conductive body 6 and a bonnet of conductive material 8 intended to close the conductive body 6.
    As described below, the contacts 4.1 to 4.4 of the bent connector 1 are each crimped to a conductor 2.1 to 2.4 of a cable 2 to several insulated conductors, further provided with an outer sheath 20 and a crimping bushing 10 at the free end of the sheath 20.
    Each contact 4.1 to 4.4 is, in the example described, bent and made of a single piece of metal according to the technology called "cut-rolled".
    Each contact 4.1 to 4.4 comprises at its front end 40 a contact portion intended to cooperate with a complementary contact portion, and at its rear end 41 a crimping portion having a cross section in U or V with two branches facing each other. to be folded toward each other around an insulated conductor of the cable, as described later.
    Depending on their position in the angled connector 1, and therefore their positioning relative to the connector elbow, the contacts are longer or shorter. Thus, as illustrated, the contacts 4.1, 4.3 arranged inside the bend are relatively shorter than the contacts 4.2, 4.4 arranged outside the bend.
    FIGS. 2 and 2A show a bent insulation 5 made of insulating material which serves as a support for the contacts 4.1 to 4.4. In the example shown, the bent insulation 5 is made in one piece. The bent insulation 5 has a front portion 50 extending along a first axis X and a rear portion 51 which extends along a second axis Y. In the example described, the X and Y axes are perpendicular but the invention may apply to any non-parallel arrangement of the X and Y axes. In the example also illustrated, the front portion 50 is generally cylindrical but the invention applies to any other geometric section.
    The front portion 50 has through openings, four in number 50.1, 50.2, 50.3, 50.4 in the example shown. The through openings 50.1 to 50.4 are each adapted to house each the front end 40 of a contact 4.1 to 4.4. The relative arrangement, in square in the illustrated example, between openings 50.1 to 50.4 ensures good mutual spacing between contacts 4.1 to 4.4.
    The front portion 50 further comprises: a wall 52 which extends between through openings in the X-Y plane and which is adapted to separate the two-to-two contacts; - A wall 53 which extends between through openings in a plane perpendicular to the X-Y plane and which is adapted to separate the short contacts 4.1, 4.3 of the long contacts 4.2, 4.4 in their front end.
    The rear portion 51 of the insulator 5 comprises in turn two grooves 54.1, 54.3 each open towards the outside of the insulator and separated from each other by a wall 55. Each groove 54.1, 54.3 is adapted to at least partly receive the rear end 41 of a contact respectively 4.1, 4.3.
    According to the invention, the rear portion 51 of the insulator 5 is configured so that the insulating part 9 comes to be inserted in a direction transverse to the Y axis of the body 5. Thus, in the example illustrated, the portion rear 51 comprises a zone 57 defined by notches and slots, in particular made on the separating wall 55, which serves as insertion and support zone of the insulating part 9. The rear portion 51 finally comprises a zone 56 defined by the vertices on either side of the indentations 57 above, which serves as a support zone of the conductive cover 8.
    Referring now to FIGS. 3, 3A and 3B, an insulating part 9 is intended to be inserted and then snap into the rear portion 51 of the insulator 5.
    In this example illustrated, the insulating part 9 has a general U shape. One of the branches 91 of the U has the function of separating each rear end 41 of the short contacts 4.1, 4.3, which is housed in a groove 54.1, 54.3 of that of the long contacts 4.2, 4.4 not received in the groove. The other of the branches 92 of the U has the function of separating each rear end 41 of the long contacts 4.2, 4.4 which is not housed in the groove 54.1, 54.3 of the cover 8 conductor. The bottom 93 of the U, more precisely the space delimited between the two parallel branches 91, 92, defines the mounting clearance of each rear end 41 of the long contacts 4.2, 4.4, not received in the groove 54.1, 54.3. The wall 93 and the branch 92 complete the insulation of the contacts with respect to the body 6 and the cover 8 conductors.
    The insulating part 9 comprising latching means 90 on the rear portion 51 of the insulator 5, once its transverse insertion performed.
    As best seen in Figure 4H, the conductive body 6 has a front portion 60 extending along a first axis and a rear portion 61 extending along a second axis. In the illustrated example, the first and second axes are perpendicular but any other arrangement is possible in relation to the angle of elbow formed by the X and Y axes of the insulator. The body 6 can be made in one piece.
    The front portion 60 of the body 6 has a through opening for accommodating the front portion 50 of the insulator 5, while the rear portion 61 has a groove adapted to receive the rear portion 51 of the insulator 5.
    The front portion 60 of cylindrical shape in the example shown is internally shaped to fix the ground contact 7 with its elastic tongues.
    As best seen in FIGS. 1 and 4H, the conductive cover 8 of the connector comprises a tongue 8 for closing the rear portion 61 of the conductive body 6 and forming the shielding part of the bent connector according to the invention 1.
    The cover 8 has a crimping portion 81 for crimping the cover 8 around the rear portion 61 of the conductive body 6. Π also has a crimping portion 82 for crimping the cover around the external insulating sheath 20 of the cable 2. The hood 8 can be made in one piece according to the technology called "cut-rolled". The cover 8 is metallic.
    The housing 3 is for example made of polymer and is hollowed out internally, having a through passage.
    The housing 3 comprises, for example, not shown elastic fingers formed in the wall of the through passage and making it possible to provide a locking function on the front portion 60 of the conductive body 6 and thus of the bent connector 1 with the housing 3.
    The housing 3 further comprises means not shown for locking the connection assembly 11 according to the invention with a housing of a complementary connection assembly.
    We will now describe with reference to FIGS. 4A to 4L, all the steps of assembling a connection assembly 11 including the assembly of the bent connector according to the invention 1.
    Firstly, a cable 2 is provided with a plurality of insulated conductors 2.1, 2.2, 2.3, 2.4, four in the example illustrated, with an outer sheath 20 around which the sleeve 10 is crimped. The free end of the sleeve is stripped. each of the conductors 2.1 to 2.4 over a length L sufficient to allow a contact 4.1 to 4.4 to be crimped securely around (Figure 4A).
    The rear end 41 of each right-handed contact 4.1, 4.2, 4.3, 4.4, four in the example illustrated, is then crimped onto a conductor 2.1 to 2.4. More specifically, the short contacts 4.1, 4.3 are crimped on the conductors of the bottom 2.1, 2.3 and the long contacts 4.2, 4.4 are crimped on the top conductors 2.2, 2.4 (Figure 4B).
    Once the crimping of the contacts 4.1 to 4.4 is carried out, one comes to insert their front end 40 in each of the through openings 50.1 to 50.4 provided for this purpose (Figure 4C, insertion direction according to arrow I).
    Bending, at 90 ° in the illustrated example, is then performed on the contacts 4.1 to 4.4, the front end 40 of which is housed in the recesses 50.1 to 50.4 of the front portion 50 of the insulator 5 (FIG. 4D).
    The contacts 4.1 to 4.4 are then pushed into the insulator 5 until they are in position in the latter, that is to say with the front ends 40 of the contacts 4.1 to 4.4 housed completely in the front portion 50 of the 5, the rear ends 41 of the short contacts 4.1, 4.3 housed in their respective groove 54.1, 54.3 and the long contacts 4.2, 4.4 superimposed (Figure 4 E). As can be seen in this FIG. 4 E, the bending of the contacts 4.1 to 4.4 and the superposition of the long contacts 4.2, 4.4 on the short contacts 4.1, 4.4 are made such that a free space remains between the short contacts 4.1. , 4.3 and those long 42, 4.4 once their positioning in the insulation 5 with their elbow in abutment.
    In this Figure 4E, it is noted that the grooves 54.1, 54.3 and the wall 55 separating them are of sufficient length at the rear of the rear portion 51 to ensure the complete isolation of the long contacts 4.2, 4.4 between them.
    Then it is snapped into the rear portion 51 of the insulator 5, the insulating part 9 by prior insertion transversely to its axis Y (Figure 4F, direction of insertion according to the arrow C). When snapping, the branch 91 of the part 9 is inserted into the free space between short contacts 4.1, 4.3 and long contacts 4.2, 4.4.
    When the latching means ad hoc 90 is formed around the central wall of the rear portion 51, all the contacts 4.1 to 4.4 are maintained by the part 9, isolated from each other and the long contacts 4.2, 4.4 are isolated from the outside (Figure 4G). More specifically, in the illustrated example, in this latched position of the insulating part 9, the branch 91 of the U formed by the part 9 separates each rear end 41 of the short contacts 4.1, 4.3, which is housed in a groove 54.1, 54.3 that of the long contacts 4.2, 4.4 not received in the groove. The branch 92 of the U separates each rear end 41 of the long contacts 4.2, 4.4 which is not housed in the groove 54.1, 54.3 vis-à-vis the outside. The space 94 delimited by the bottom 93 between the two branches 91, 92 defines the mounting clearance of each rear end 41 of the long contacts 4.2, 4.4, not received in the groove 54.1, 54.3. At this stage, the angled multi-contact connector 1 according to the invention is assembled with the contacts 4.1 to 4.4 crimped to the insulated conductors 2.1 to 2.4 of the cable, which are held in the insulator 5 by their insertion in the front portion 50 and the blocking ensured by the insulating part 9 in the rear portion of the insulation 5.
    To finalize the assembly of a complete connection assembly 11 incorporating the bent connector according to the invention, the following steps are then carried out.
    The front portion 50 of the insulator 5 is introduced into the front portion 60 of a bent conductive body 6 (FIG. 4H, direction of thrust of the insulator 5 according to arrow P).
    The conductive cover 8 is then closed on the rear portion 61 of the bent body 6, so as to maintain inside the body the connector portion having the contacts 4.1 to 4.4 crimped on the conductors 2.1 to 2.4 of the cable 2 (FIG. 41). .
    Crimp 8 is then crimped on the rear portion 61 of the conductive body 6 by means of the crimping portion 81 and crimping on the outer insulating sheath 20 of the cable 2 by means of the crimping portion 82 (FIG. 4J, crimping symbolized by arrow S).
    Once this crimping of the cover 8 made, we obtain a bent connector 1 which is shielded at its periphery.
    To finalize the assembly of the connection assembly, it comes to pre-insert the conductive body 6 with the cable 2 in the housing 3 (Figure 4K), then a complete insertion that triggers the snap of the front portion 60 the conductive body 6 in the housing 3 through its inner tabs not shown (Figure 4L). The connection assembly 11 finally assembled integrating the angled multi-contact connector according to the invention with its conductive cover crimped on the outer sheath 20 of the cable 2 is shown in FIG.
    FIG. 6 shows an advantageous variant of the insulating part 9 according to the invention: one or more polarizers 95 made in the form of protrusion at one or more corners of the insulating face 92 make it possible to avoid any error in mounting the part 9 in the insulation 5.
    FIG. 7 shows another advantageous variant of the insulating part 9 according to the invention: the insulating face 92 perfectly fits the peripheral wall of the rear portion 51 of the insulator 5 by closing the latter in a way.
    The modes illustrated in FIGS. 1 to 7 relate to four contacts 4.1 to 4.4. One can of course consider implementing the solution of the invention for a connector bent to a greater number of contacts.
    FIGS. 8 to 8B illustrate an eight-contact variant 4.1 to 4.8 including a row of four short contacts 4.1, 4.3, 4.5, 4.7 on which is superposed a row of four long contacts 4.2, 4.4, 4.6, 4.8.
    The short contacts 4.1, 4.3, 4.5, 4.7 are thus individually received and maintained in one of the four parallel grooves 54.1, 54.3, 54.5, 54.7 formed for this purpose in the rear portion 51 of the insulator 5.
    In this variant illustrated, the insulating part 9 has the same U-shape as that provided for the modes of Figures 1 to 7, only the branches 91, 92 are longer in order to isolate the number of upper contacts.
    As shown in FIG. 8A, the eight contacts 4.1 to 4.8 are maintained in the insulator 5 by their insertion in the front portion 50 and blocked by the insulating part 9 in the rear portion 51 of the insulator 5.
    As shown in FIG. 8B, the eight contacts 4.1 to 4.8 are then individually crimped to the insulated conductors 2.1 to 2.8 of the cable.
    Of course, the invention is not limited to the implementation examples which have just been described. Other variants and improvements may be envisaged without departing from the scope of the invention.
    In all the modes illustrated in FIGS. 1 to 8B, the contacts 4.1 to 4.8 are distributed in two superposed rows one on the other, and the insulating part 9 has a U shape with one of the branches 91 which serves to isolate a row of short contacts 4.1, 4.3, 45, 4.7 relative to that of the long contacts 4.2, 4.4, 4.6, 4.8, and the other of the branches 92 which serves to isolate the long contacts 4.2, 4.4, 4.6, 4.8 of the cover 8 driver.
    In the context of the invention, one can very well envisage arranging the contacts on a greater number of superimposed rows, with the shorter contacts in the row from below to the bottom of the grooves, the long contacts in the row from above , and those of intermediate length in the intermediate row or rows.
    In this mode, the insulating part 9 then has a general shape in multiple U contiguous to each other, in particular in double U and the grooves of the insulator 5 are deeper in order to accommodate a higher number of superposed rows, minus three. In this mode, the lower branch 91 and the branch or branches inside the multiple U still isolate the contacts superimposed between them and the outer branch 92 can isolate the rows of the longest contacts of the conductive cover 8.
    FIGS. 9 to 9B illustrate a variant that is always eight contacts 4.1 to 4.8 but unlike the variant of FIGS. 8 to 8B, here superimposed in four rows of two contacts.
    In this variant illustrated, the row of the two shortest contacts 4.1, 4.2 is received and kept parallel individually in one of the two parallel grooves 54.1, 54.2 formed for this purpose in the rear portion 51 of the insulator 5.
    In this variant illustrated, the insulating part 9 has a form in triple U contiguous delimited by four branches 91, 92, 96, 97. As in the illustrated variants already commented, the outer insulation face 92 according to this variant of Figures 9 to 9B is also perfectly fit the rear portion of the peripheral wall 51 of the insulation 5 by closing the latter somehow. One 97 of the two branches 96, 97 internal to the insulating part 9 comprises a polarizer 95 formed in the form of protrusion at one of the corners of the branch and which makes it possible to avoid any error of assembly of the part 9 in the insulation 5.
    As shown in FIG. 9A, the eight contacts 4.1 to 4.8 are superimposed two-by-two and held in the insulator 5 by their insertion in the front portion 50 and blocked by the insulating part 9 in the rear portion 51 of the insulator 5.
    As shown in FIG. 9B, the eight contacts 4.1 to 4.8 are then individually crimped to the insulated conductors 2.1 to 2.8 of the cable.
    If in the illustrated embodiments, the contacts illustrated 4.1 to 4.8 are crimped to the conductors 2.1 to 2.8 of the cable, it is very likely that they are welded to them.
    Also if in the embodiments shown, the contacts illustrated 4.1 to 4.8 are bent after their partial insertion in the front portion 50 of the insulator 5, they can be also before their partial insertion. This variant can be applied to welded or crimped contacts.
    Furthermore, if the insulating part 9 is snap-fitted in the insulator 5, it can also be mounted by force fitting into the latter.
    In addition, if the external insulating face 92 of the insulating part 9 illustrated is made with openings, it can very well be considered to achieve full.
