Description

La présente invention concerne les connecteurs électriques comportant plusieurs éléments de contact et destinés à être accouplés à un connecteur complémentaire. Elle concerne plus particulièrement les connecteurs électriques du type défini par le préambule de la revendication 1, qui sont couramment utilisés à l'heure actuelle.The present invention relates to electrical connectors comprising several contact elements and intended to be coupled to a complementary connector. It relates more particularly to electrical connectors of the type defined by the preamble of claim 1, which are commonly used at present.

On connaît par ailleurs (FR-A-2 265 193) un connecteur complexe, ayant un corps isolant avant percé de passages de réception de contacts et d'appui d'une collerette de ces contacts, une plaquette isolante venant s'appliquer contre le corps et munie de doigts de verrouillage et des moyens destinés à maintenir la plaquette en appui contre le corps isolant avant.There is also known (FR-A-2 265 193) a complex connector, having an insulating body before pierced with passages for receiving contacts and for supporting a flange of these contacts, an insulating plate being applied against the body and provided with locking fingers and means intended to keep the plate in abutment against the front insulating body.

L'invention vise notamment à fournir un connecteur dont le démontage et le montage soient faciles, restant cependant de constitution simple.The invention aims in particular to provide a connector whose disassembly and assembly are easy, however remaining simple in constitution.

Dans ce but, l'invention propose un connecteur ci-dessus défini, conforme à la partie caractérisante de la revendication 1. Des caractères secondaires sont exposés dans les revendications dépendantes.To this end, the invention provides a connector defined above, in accordance with the characterizing part of claim 1. Secondary characters are set out in the dependent claims.

Cette disposition permet de retirer tous les contacts sans séparation de la plaquette.This arrangement allows all the contacts to be removed without separating the plate.

L'invention sera mieux comprise à la lecture de la description qui suit d'un mode particulier de réalisation, donné à titre d'exemple non limitatif. La description se réfère aux dessins qui l'accompagnent, dans lesquels :

  • la figure 1 montre schématiquement, en coupe suivant un plan passant par l'axe, deux connecteurs destinés à coopérer, l'un des connecteurs étant représenté pour moitié en position accouplée, pour moitié en position désaccouplée ;
  • la figure 2 montre le double accrochage des connecteurs de la figure 1, en coupe suivant un plan passant par l'axe, différent de celui de la figure 1 ;
  • la figure 3 est une vue en coupe suivant la ligne III-III de la figure 2.
The invention will be better understood on reading the following description of a particular embodiment, given by way of non-limiting example. The description refers to the accompanying drawings, in which:
  • Figure 1 shows schematically, in section along a plane passing through the axis, two connectors intended to cooperate, one of the connectors being shown half in the coupled position, half in the uncoupled position;
  • Figure 2 shows the double hooking of the connectors of Figure 1, in section along a plane passing through the axis, different from that of Figure 1;
  • Figure 3 is a sectional view along line III-III of Figure 2.

Les connecteurs coopérants montrés en figures 1 à 3 sont notamment utilisables en construction automobile où une double sécurité d'accrochage est recommandée. Ils constituent l'un une fiche 10 et l'autre une embase 10a. Chacun a plusieurs éléments de contact, qui sont représentés comme des douilles 12 sur le connecteur formant fiche, des broches 12a sur le connecteur formant embase.The cooperating connectors shown in FIGS. 1 to 3 can be used in particular in automobile construction where a double attachment security is recommended. One constitutes a plug 10 and the other a base 10a. Each has several contact elements, which are shown as sockets 12 on the plug connector, pins 12a on the base connector.

La fiche 10 comprend un corps isolant avant 18 percé de passages parallèles de réception des contacts 12. Chaque passage présente un épaulement 20 dirigé vers l'arrière, destiné à servir de butée pour une collerette 22 correspondante prévue sur le contact et donc à fixer la position de ce dernier. La partie arrière du corps isolant constitue une jupe tubulaire destinée à recevoir une plaquette 24 de rétention des contacts. Cette plaquette présente un jeu de doigts de verrouillage flexibles 25 dirigés vers l'avant pour chaque passage. Dans le mode de réalisation représenté, les doigts 25 ont au repos une forme telle qu'ils délimitent un passage de dimension inférieure à la section droite d'une collerette 22 des éléments de contact, destinés à venir en appui contre l'épaulement 20. Ils doivent donc s'écarter pour permettre l'insertion ou l'extraction des contacts. Cet écartement est interdit, lorsque la fiche est assemblée, par la paroi d'un chambrage 48 prévue dans le corps isolant avant 18. Dans un mode avantageux de réalisation, les doigts présentent un épaississement terminal de façon à glisser sur le fût des éléments de contact et à ne subir aucune déformation et aucune contrainte de flexion permanente.The plug 10 comprises a front insulating body 18 pierced with parallel passages for receiving the contacts 12. Each passage has a shoulder 20 directed towards the rear, intended to serve as a stop for a corresponding flange 22 provided on the contact and therefore to fix the position of the latter. The rear part of the insulating body constitutes a tubular skirt intended to receive a contact retention plate 24. This plate has a set of flexible locking fingers 25 directed forward for each passage. In the embodiment shown, the fingers 25 have at rest a shape such that they delimit a passage of dimension smaller than the cross section of a flange 22 of the contact elements, intended to come into abutment against the shoulder 20. They must therefore move apart to allow the insertion or extraction of the contacts. This spacing is prohibited, when the plug is assembled, by the wall of a recess 48 provided in the front insulating body 18. In an advantageous embodiment, the fingers have a terminal thickening so as to slide on the barrel of the elements of contact and to undergo no deformation and no permanent bending stress.

Dans le mode de réalisation montré à titre d'exemple, les moyens de fixation de la plaquette 24 sur le corps isolant 18 comprennent des pattes 26 dirigées vers l'arrière, au nombre de deux par exemple, terminées par des crochets en forme de fourche, venant s'engager dans des encoches circonférentielles terminales de la jupe du corps isolant avant. Les pattes 26 maintiennent assemblés les contacts 12, la plaquette 24 et le corps isolant avant 18, tout en permettant le démontage.In the embodiment shown by way of example, the means for fixing the plate 24 to the insulating body 18 comprise tabs 26 directed towards the rear, two in number for example, terminated by fork-shaped hooks , coming to engage in terminal circumferential notches of the skirt of the front insulating body. The tabs 26 keep the contacts 12, the plate 24 and the front insulating body 18 assembled, while allowing disassembly.

Il est souvent nécessaire que la plaquette 24 ne puisse être insérée dans le corps isolant 18 que dans une seule orientation. Pour cela des moyens d'indexage peuvent être prévus. Les figures 2 et 3, montrent des moyens d'indexage de chaque connecteur qui comportent des rainures longitudinales 50 ménagées dans le corps isolant avant et des clavettes de forme correspondante 52 prévues sur la plaquette.It is often necessary that the plate 24 can only be inserted into the insulating body 18 in one orientation. For this, indexing means can be provided. Figures 2 and 3 show means of indexing each connector which have longitudinal grooves 50 formed in the front insulating body and keys of corresponding shape 52 provided on the wafer.

Pour éviter l'échappement total de la plaquette lorsque les pattes 26 sont décrochées, des rebords 54 peuvent être prévus aux extrémités des rainures 50. Le mouvement de recul de la plaquette est alors limité par la venue en appui de la tranche arrière des clavettes 52. L'élasticité des pièces permet cependant de les séparer en cas de besoin.To avoid total escape of the wafer when the tabs 26 are off, flanges 54 may be provided at the ends of the grooves 50. The backward movement of the wafer is then limited by the abutment of the rear edge of the keys 52 The elasticity of the parts, however, allows them to be separated if necessary.

Un raccord intermédiaire 32, pouvant être en plusieurs pièces assemblées, est fixé sur le corps isolant de façon amovible et constitue une transition avec le raccord de câble. Il peut de plus compléter la retenue de la plaquette. Il présente une partie avant destinée à se glisser sur l'arrière du corps isolant avant 18 et une partie arrière venant s'appuyer contre la fourche terminale des pattes 26. Un joint torique 56 peut être prévu entre le raccord intermédiaire 32 et le corps isolant 18 pour assurer l'étanchéité.An intermediate connector 32, which can be made of several assembled parts, is fixed on the insulating body in a removable manner and constitutes a transition with the connector. of cable. It can also supplement the retention of the wafer. It has a front part intended to slide on the rear of the front insulating body 18 and a rear part which comes to rest against the end fork of the legs 26. An O-ring 56 can be provided between the intermediate connector 32 and the insulating body 18 for sealing.

Les moyens de fixation du raccord intermédiaire comportent des pattes élastiques d'accrochage 60 prolongeant le raccord 32 vers l'avant, venant s'encliqueter dans des évidements circonférentiels du corps isolant 18, derrière une collerette 66. Des bossages peuvent être prévus dans les évidements 62 pour n'autoriser le montage du raccord intermédiaire 32 que dans une seule orientation, lorsque cela est nécessaire. Les bossages évitent alors également la rotation du raccord intermédiaire. Ces bossages peuvent notamment être prévus pour s'insérer chacun entre deux pattes élastiques 60.The means for fixing the intermediate connector comprise elastic hooking lugs 60 extending the connector 32 forwards, snapping into circumferential recesses of the insulating body 18, behind a flange 66. Bosses can be provided in the recesses 62 to authorize the fitting of the intermediate connector 32 in only one orientation, when necessary. The bosses then also prevent rotation of the intermediate fitting. These bosses can in particular be provided to be inserted each between two elastic tabs 60.

Les connecteurs 10 et 10a sont munis de moyens de fixation complémentaires. Dans le cas de la fiche 10, ces moyens comportent une bague de verrouillage 16 destinée à se visser sur un filetage externe du corps isolant avant 18a de l'embase 10a. La bague de verrouillage 16 peut être munie, à l'avant, de fentes de verrouillage coopérant avec des tenons prévus sur le corps isolant 18a, conformément à la disposition décrite dans le document FR-A-2 632 783 auquel on pourra se reporter.The connectors 10 and 10a are provided with complementary fixing means. In the case of the plug 10, these means comprise a locking ring 16 intended to be screwed onto an external thread of the front insulating body 18a of the base 10a. The locking ring 16 can be provided, at the front, with locking slots cooperating with pins provided on the insulating body 18a, in accordance with the arrangement described in document FR-A-2 632 783 to which reference may be made.

La bague de verrouillage 16 est prolongée à l'arrière, dans le mode particulier de réalisation donné à titre d'exemple, par des pattes élastiques 64 pouvant avoir plusieurs fonctions et notamment celle de retenir la bague en translation sur le raccord intermédiaire 32 dans le cas représenté, directement sur le corps isolant dans d'autres cas. Ces pattes 64 présentent un redan tourné vers l'arrière et qui, lorsque la bague est en place, est en regard d'un cran circonférentiel d'encliquetage 70 prévu sur le raccord intermédiaire 32. Le recul de la bague est ainsi évité. Vers l'avant, la bague est en appui, lorsqu'elle est en place, contre la collerette 66 qui lui permet de tourner.The locking ring 16 is extended at the rear, in the particular embodiment given by way of example, by elastic tabs 64 which can have several functions and in particular that of retaining the ring in translation on the intermediate connector 32 in the case shown, directly on the insulating body in other cases. These tabs 64 have a step facing back and which, when the ring is in place, is in look of a circumferential latching notch 70 provided on the intermediate connector 32. The recoil of the ring is thus avoided. Forward, the ring is in support, when it is in place, against the flange 66 which allows it to rotate.

L'assemblage du connecteur 10 qui vient d'être décrit peut s'effectuer de la façon suivante.The assembly of the connector 10 which has just been described can be carried out as follows.

La bague de verrouillage 16 est glissée sur le câble (non représenté) qui peut déjà être muni de ses contacts terminaux. Le raccord intermédiaire 32 est mis en place sur le câble. La plaquette est insérée dans le corps isolant avant, mais laissée dans la position de retrait maximum défini par l'appui contre les rebords 54. Les contacts peuvent alors être montés à travers la plaquette 24, par l'arrière. Ils s'encliquettent en dépassant les doigts élastiques 25. Une fois les contacts en place, on pousse la plaquette 24 vers l'avant jusqu'à ce que les pattes élastiques de verrouillage 26 viennent s'accrocher dans les fentes à l'arrière du corps isolant.The locking ring 16 is slid over the cable (not shown) which can already be provided with its terminal contacts. The intermediate connector 32 is placed on the cable. The plate is inserted into the front insulating body, but left in the maximum withdrawal position defined by the support against the flanges 54. The contacts can then be mounted through the plate 24, from the rear. They snap past the elastic fingers 25. Once the contacts in place, the plate 24 is pushed forward until the elastic locking tabs 26 come to catch in the slots at the rear of the insulating body.

Une fois la plaquette encliquetée dans le corps, le raccord intermédiaire 32 est engagé sur le corps isolant, par simple pression. Les pattes 60 s'écartent Jusqu'à ce qu'elles arrivent dans les évidements.Once the plate is snapped into the body, the intermediate connector 32 is engaged on the insulating body, by simple pressure. The legs 60 move apart until they reach the recesses.

La bague de verrouillage 16 peut alors être avancée jusqu'à ce qu'elle vienne s'appuyer contre la collerette 66, devant les évidements 62. A ce moment-là, les pattes élastiques 64 ont dépassé le cran 70.The locking ring 16 can then be advanced until it comes to bear against the flange 66, in front of the recesses 62. At this time, the elastic tabs 64 have exceeded the notch 70.

Le démontage s'effectue par des opérations inverses.Disassembly is carried out by reverse operations.

Pour démonter la bague de verrouillage 16, on écarte les pattes élastiques 64 à l'aide d'un outil et on tire la bague 16 vers l'arrière. Le raccord intermédiaire 32 doit d'abord être dégagé des moyens qui le retiennent, pouvant être constitués par un manchon-raccord taraudé, vissé sur la partie arrière filetée du raccord intermédiaire 32. Puis le raccord intermédiaire 32 peut être tiré vers l'arrière pour dégager ses pattes élastiques 60.To disassemble the locking ring 16, the elastic tabs 64 are spread apart using a tool and the ring 16 is pulled back. The intermediate connection 32 must first be released from the means which hold it, which may be constituted by a threaded connection sleeve, screwed onto the threaded rear part of the intermediate connection 32. Then the intermediate connection 32 can be pulled towards the rear to release its elastic legs 60.

Il devient alors possible de démonter les contacts. On pince les pattes élastiques 26 pour les dégager des fentes d'accrochage, par exemple à l'aide d'un tournevis, puis on tire la plaquette vers l'arrière Jusqu'à venue en butée contre le rebord 54. Chaque contact peut alors être enlevé par traction sur son câble : les doigts élastiques 25 s'ouvrent sous la pression.It then becomes possible to dismantle the contacts. Pinch the elastic tabs 26 to disengage them from the hooking slots, for example using a screwdriver, then pull the plate backwards until it comes into abutment against the flange 54. Each contact can then be removed by pulling on its cable: the elastic fingers 25 open under pressure.

Le raccord intermédiaire peut être complété par un col interne 68 d'appui sur un passe-fil (non représenté) interposé entre lui et la plaquette 24. Ce col peut également, ou uniquement, être prévu pour interdire le décrochage des pattes 26.The intermediate connector can be completed by an internal neck 68 bearing on a grommet (not shown) interposed between it and the plate 24. This neck can also, or only, be provided to prevent the dropout of the tabs 26.

L'embase 10a constituant le connecteur complémentaire peut avoir une constitution similaire à celle de la fiche 10. La figure 3 montre les clavettes d'indexage de sa plaquette 24a dans le corps isolant 10a qui constitue également le bottier muni du filetage de réception de la bague 16. On voit que les clavettes ont deux largeurs différentes pour assurer une polarisation angulaire.The base 10a constituting the complementary connector can have a constitution similar to that of the plug 10. FIG. 3 shows the indexing keys of its plate 24a in the insulating body 10a which also constitutes the boot housing provided with the thread for receiving the ring 16. We see that the keys have two different widths to ensure angular polarization.

Les pièces autres que les corps isolants et les plaquettes de retenue peuvent être constituées en tout matériau approprié, et notamment en matière plastique chargée.The parts other than the insulating bodies and the retaining plates can be made of any suitable material, and in particular of loaded plastic.
