Description

L'invention concerne, de manière générale, le raccordement électrique et la fixation mécanique de connecteurs.The invention relates, in general, to the electrical connection and the mechanical fixing of connectors.

De tels connecteurs peuvent être destinés à véhiculer des signaux d'alimentation ou de commande. Ils comportent par exemple un ensemble de modules de contacts, respectivement mâles et femelles, qui sont destinés à coopérer lors du raccordement.Such connectors can be intended to convey power or control signals. They comprise for example a set of contact modules, respectively male and female, which are intended to cooperate during connection.

L'assemblage des connecteurs nécessite des efforts d'assemblage qui peuvent être importants en fonction de la densité de points, c'est-à-dire de contacts, à connecter. Ces efforts sont liés à l'interpénétration des contacts entre eux. En effet, les contacts mâles doivent entrer en contact avec les contacts femelles, qui sont serrants, et qui opposent une résistance au montage. Lorsque les contacts sont hermaphrodites, le serrage est engendré de part et d'autre du connecteur et des efforts de montage peuvent également être importants.The assembly of the connectors requires assembly efforts which can be significant depending on the density of points, that is to say of contacts, to be connected. These efforts are linked to the interpenetration of contacts between them. Indeed, the male contacts must come into contact with the female contacts, which are tightening, and which oppose a resistance to the assembly. When the contacts are hermaphroditic, the tightening is generated on either side of the connector and mounting forces can also be significant.

En outre, les cadences de montage engendrent des problématiques de coût liées au temps d'installation et de maintenance des connecteurs. L'utilisation d'outils réduit cette cadence et monopolise en permanence une main d'un opérateur.In addition, the assembly rates generate cost issues related to the installation and maintenance time of the connectors. The use of tools reduces this rate and permanently monopolizes an operator's hand.

Enfin, il est nécessaire de pouvoir analyser rapidement le bon verrouillage des connecteurs, ce qui peut être incompatible avec les systèmes de raccordement conventionnels par vissage car les couples de serrage ne peuvent être appréciés visuellement, ou avec les systèmes de raccordement conventionnels par clipsage ou à quart de tour qui peuvent rester partiellement verrouillés sans qu'un examen visuel permette d'identifier le raccordement imparfait.Finally, it is necessary to be able to quickly analyze the correct locking of the connectors, which may be incompatible with conventional screw connection systems because the tightening torques cannot be assessed visually, or with conventional connection systems by clipping or quarter turn which can remain partially locked without visual inspection identifying the imperfect connection.

Le document DE 198 37 896 décrit un connecteur électrique comprenant des connecteurs males et des connecteurs femelles, ainsi qu'un élément d'accouplement déplaçable.The document FROM 198 37 896 discloses an electrical connector comprising male and female connectors, as well as a movable mating member.

Le document US 2004/0002240 décrit aussi un dispositif connecteur comprenant un boîtier stationnaire, un boîtier mobile et un levier glissant.The document US 2004/0002240 also describes a connector device comprising a stationary housing, a movable housing and a sliding lever.

Toutefois, les dispositifs de ces documents sont relativement difficiles à mettre en œuvre, en particulier d'une seule main.However, the devices of these documents are relatively difficult to implement, in particular with one hand.

Au vu de ce qui précède, le but de l'invention est de proposer un système de raccordement de connecteurs ne nécessitant aucun outil pour l'accouplement et le désaccouplement du système, qui puisse être mis en œuvre de façon aisée, d'une seule main, et qui procure une assistance au montage et au démontage afin de réduire les efforts d'accouplement et de désaccouplement.In view of the foregoing, the aim of the invention is to provide a connector connection system requiring no tool for coupling and uncoupling of the system, which can be implemented easily, with a single hand, and which provides a assistance with assembly and disassembly in order to reduce coupling and uncoupling efforts.

L'invention a donc pour objet un système de raccordement d'au moins une paire de connecteurs appariés selon la revendication comprenant une platine comprenant une ouverture pour chaque paire de connecteurs et sur laquelle vient se fixer un premier connecteur de ladite paire et un verrou déplaçable latéralement par rapport à la platine et au premier connecteur, ledit verrou étant déplaçable dans une première position apte à permettre l'insertion du deuxième connecteur de ladite paire jusqu'à la mise en contact des connecteurs et dans une deuxième position stable d'accouplement et de verrouillage des connecteurs.The subject of the invention is therefore a system for connecting at least one pair of matched connectors according to claim comprising a plate comprising an opening for each pair of connectors and on which is fixed a first connector of said pair and a movable lock. laterally with respect to the plate and to the first connector, said lock being movable in a first position capable of allowing the insertion of the second connector of said pair until the connectors come into contact and in a second stable coupling position and locking connectors.

La première position correspond donc à une position ouverte du verrou, dans laquelle le verrou est par exemple dans une position reculée, tandis que la deuxième position correspond à une position fermée du verrou dans laquelle le verrou est par exemple en position avancée.The first position therefore corresponds to an open position of the lock, in which the lock is for example in a retracted position, while the second position corresponds to a closed position of the lock in which the lock is for example in the advanced position.

Selon une autre caractéristique du système de raccordement selon l'invention, le verrou comporte un ensemble d'au moins une première rampe sur laquelle s'appuie un pion prévu sur le deuxième connecteur lors du déplacement du verrou dans la deuxième position.According to another characteristic of the connection system according to the invention, the lock comprises an assembly of at least a first ramp on which rests a pin provided on the second connector when the lock is moved into the second position.

Le verrou comporte en outre un ensemble d'au moins une deuxième rampe parallèle à la première rampe et sur laquelle s'appuie le pion lors du déplacement du verrou dans la première position pour le désaccouplement des connecteurs.The lock further comprises a set of at least one second ramp parallel to the first ramp and on which the pin rests when moving the lock into the first position for uncoupling the connectors.

Dans un mode de réalisation, les rampes débouchent dans un godron de verrouillage.In one embodiment, the ramps open into a locking gadroon.

Selon encore une autre caractéristique, le premier et le deuxième connecteurs comportent respectivement une embase d'extrémité équipée de moyens de fixation sur la platine et une fiche sur laquelle sont prévus le ou les pions.According to yet another characteristic, the first and the second connectors respectively comprise an end base fitted with means for fixing to the plate and a plug on which the pin or pins are provided.

Le deuxième connecteur comporte une queue de commande du déplacement du verrou dans la première position reculée, pour s'appuyer contre une rampe d'extrémité du verrou quand la fiche du deuxième connecteur est approchée de la platine.The second connector has a tail for controlling the movement of the lock in the first retracted position, to rest against an end ramp of the lock when the plug of the second connector is approached to the plate.

On prévoira alors avantageusement un élément élastique de rappel sollicitant le verrou dans la première position.An elastic return element will then advantageously be provided urging the latch in the first position.

On prévoira en outre, avantageusement, un repère visuel placé sur le trajet du verrou et visible uniquement lorsque le verrou est en position de verrouillage.Advantageously, there will also be a visual marker placed on the path of the lock and visible only when the lock is in the locked position.

Dans un mode de réalisation, le système comporte une couche de matériau compressible adaptée pour être comprimée en fin de course d'accouplement des connecteurs ou en début de course de désaccouplement des connecteurs.In one embodiment, the system comprises a layer of compressible material suitable for being compressed at the end of the coupling travel of the connectors or at the start of the uncoupling travel of the connectors.

Dans un mode de réalisation, le système comporte une coiffe de protection contre des rayonnements électromagnétiques.In one embodiment, the system includes a cap for protection against electromagnetic radiation.

D'autres buts, caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante, donnée uniquement à titre d'exemple non limitatif et faite en référence aux dessins annexés, sur lesquels :

  • les figures 7a à 7f illustrent la cinématique de désaccouplement des connecteurs au moyen d'un système de raccordement selon l'invention.
Other objects, characteristics and advantages of the invention will become apparent on reading the following description, given solely by way of non-limiting example and made with reference to the appended drawings, in which:
  • the figure 1 is an exploded perspective view of a connection system according to the invention;
  • the figures 2a, 2b and 2c show various embodiments of the system plate of the figure 1 ;
  • the figure 3 shows the lock of the connection system of the figure 1 ;

  • the figures 7a to 7f illustrate the kinematics of uncoupling of the connectors by means of a connection system according to the invention.

On se référera tout d'abord aux figures 1 à 5 qui illustrent les principaux éléments d'un système de raccordement de connecteurs appariés selon l'invention, désigné par la référence numérique générale 1.We will first of all refer to figures 1 to 5 which illustrate the main elements of a mating connector connection system according to the invention, designated by the general reference numeral 1.

Dans l'application envisagée, nullement limitative, ce système de raccordement 1 est destiné à procurer une assistance au raccordement de deux connecteurs, respectivement mâle et femelle, pour une application avionique.In the envisaged application, which is in no way limiting, this connection system 1 is intended to provide assistance in the connection of two connectors, respectively male and female, for an avionics application.

Comme on le sait, les connecteurs comportent classiquement un ensemble de modules de contacts, ayant un ensemble de contacts, mâles ou femelles, prévus aux extrémités de conducteurs à raccorder.As is known, connectors conventionally comprise a set of contact modules, having a set of contacts, male or female, provided at the ends of conductors to be connected.

Comme on le voit sur la figure 1, le système de raccordement comporte essentiellement : une platine 2 munie d'ouïes 3, ici au nombre de quatre, pour la fixation du système de raccordement sur un support de montage ; un verrou 4 déplaçable transversalement, c'est-à-dire dans le plan de la platine 2, entre une première position reculée, correspondant à une position ouverte du verrou et une deuxième position avancée correspondant à une position fermée du verrou ; une embase 5 prévue à une extrémité d'un premier connecteur à apparier et qui vient se fixer sur la platine 2 ; et une fiche 6 prévue à une extrémité d'un deuxième connecteur à apparier.As seen on the figure 1 , the connection system essentially comprises: a plate 2 provided with louvers 3, here four in number, for fixing the connection system on a mounting support; a lock 4 movable transversely, that is to say in the plane of the plate 2, between a first retracted position, corresponding to an open position of the lock and a second advanced position corresponding to a closed position of the lock; a base 5 provided at one end of a first connector to be matched and which is fixed on the plate 2; and a plug 6 provided at one end of a second connector to be matched.

Comme le montrent les figures 2a et 2b, la platine 2 comporte un ensemble d'ouvertures 7 dont le nombre dépend du nombre de connecteurs à raccorder. Bien que le nombre d'ouvertures ne soit pas limitatif, dans les divers modes de réalisation illustrés, la platine 2 peut comporter une, trois ou cinq ouvertures pour le raccordement d'une, trois ou cinq paires de connecteurs.As the figures 2a and 2b , the plate 2 comprises a set of openings 7, the number of which depends on the number of connectors to be connected. Although the number of openings is not limiting, in the various embodiments illustrated, the plate 2 can include one, three or five openings for the connection of one, three or five pairs of connectors.

Pour chaque ouverture, la platine comporte une patte 8 pour la fixation par vissage de l'embase 5 du premier connecteur. Le bord périphérique de chaque ouverture 7 comporte par ailleurs un ensemble de reliefs délimitant une empreinte servant à recevoir l'embase 5.For each opening, the plate has a tab 8 for fixing by screwing the base 5 of the first connector. The peripheral edge of each opening 7 also comprises a set of reliefs delimiting an indentation serving to receive the base 5.

En ce qui concerne le verrou 4, celui-ci a essentiellement une forme en U et comporte deux branches latérales 4a et 4b réunies par une base 4c pourvue d'une patte supérieure 4d recourbée destinée à être manœuvrée manuellement.As regards the lock 4, the latter has essentially a U-shape and comprises two lateral branches 4a and 4b joined by a base 4c provided with a curved upper tab 4d intended to be operated manually.

Chaque branche 4a et 4b du verrou comporte un ensemble de fentes, telles que 4e, délimitant chacune une première rampe 4f et une deuxième rampe 4g s'étendant parallèlement et servant respectivement lors du raccordement des connecteurs et l'autre lors du désaccouplement. Comme on le voit, chacune des fentes 4e débouche dans un godron d'extrémité 4h.Each branch 4a and 4b of the lock comprises a set of slots, such as 4th, each delimiting a first ramp 4f and a second ramp 4g extending in parallel and serving respectively when connecting the connectors and the other when disconnecting. As can be seen, each of the 4th slots opens into a 4h end gadroon.

En se référant à la figure 4, l'embase 5, qui est prévue à une extrémité d'un premier connecteur à raccorder, constitue une pièce de montage dans laquelle vient se loger le premier connecteur C1, ou qui est venue de matière avec ce dernier, et comporte, dans cet exemple, une patte 5a d'extrémité dotée d'un orifice 5b pour la fixation de l'embase au moyen d'une vis V (figure 1) sur la platine 2. Bien entendu, on pourrait, en variante, utiliser tout autre moyen approprié pour la fixation de l'embase sur la platine, par exemple un clipsage une soudure, ...With reference to the figure 4 , the base 5, which is provided at one end of a first connector to be connected, constitutes a mounting part in which the first connector C1 is housed, or which is integral with the latter, and comprises, in this example, an end bracket 5a provided with a hole 5b for fixing the base by means of a screw V ( figure 1 ) on the plate 2. Of course, one could, as a variant, use any other suitable means for fixing the base on the plate, for example a clipping a weld, ...

Comme montré sur la figure 5, la fiche 6 constitue également une pièce de montage dans laquelle vient se loger le deuxième connecteur C2 à raccorder ou qui est venue de matière avec ce dernier.As shown on the figure 5 , the plug 6 also constitutes an assembly part in which is housed the second connector C2 to be connected or which is integral with the latter.

Il comporte essentiellement une queue 6a qui est destinée à provoquer le déplacement du verrou en début de phase de raccordement et un ensemble de pions 6b dont le nombre correspond aux fentes 4e et qui sont destinés à coopérer avec les rampes 4f et 4g lors de l'accouplement, d'une part et lors du désaccouplement, d'autre part, des connecteurs. Le nombre et la position des pions et des fentes est choisi de manière à permettre un déplacement de la fiche en translation, dans l'axe des contacts, lors du déplacement du verrou.It essentially comprises a tail 6a which is intended to cause the movement of the lock at the start of the connection phase and a set of pins 6b the number of which corresponds to the slots 4e and which are intended to cooperate with the ramps 4f and 4g during the coupling, on the one hand and during uncoupling, on the other hand, of the connectors. The number and position of the pins and of the slots is chosen so as to allow a displacement of the plug in translation, in the axis of the contacts, during the displacement of the lock.

En revenant à la figure 3, on notera que, pour faciliter le déplacement du verrou 4, la zone d'extrémité des pattes 4a et 4b comporte une rampe inclinée, telle que 4i, sur laquelle s'appuie l'extrémité de la queue 6a.Returning to the figure 3 , it will be noted that, to facilitate movement of the latch 4, the end zone of the tabs 4a and 4b comprises an inclined ramp, such as 4i, on which the end of the tail 6a rests.

On se référera maintenant aux figures 6a à 6i qui illustrent la cinématique de raccordement des deux connecteurs au moyen d'un système de raccordement qui vient d'être décrit.We will now refer to figures 6a to 6i which illustrate the kinematics of connection of the two connectors by means of a connection system which has just been described.

On notera que le premier connecteur et l'embase qu'il porte sont fixes, en étant vissés sur la platine 2, tandis que la fiche et le connecteur correspondant constituent une partie mobile et amovible qui est dissociée du système de raccordement jusqu'à sa connexion.It will be noted that the first connector and the base which it carries are fixed, by being screwed onto the plate 2, while the plug and the corresponding connector constitute a movable and removable part which is dissociated from the connection system until its connection.

De même, avant la mise en œuvre de la procédure de raccordement des connecteurs, le verrou 4 est inséré dans l'ouverture de la platine, et entre la platine 3 et l'embase 5 de sorte que la patte 4d soit accessible du côté de la platine 2 opposé à l'embase 5.Similarly, before the implementation of the connector connection procedure, the lock 4 is inserted into the opening of the plate, and between the plate 3 and the base 5 so that the tab 4d is accessible from the side of the plate. plate 2 opposite the base 5.

Lors d'une première phase, la fiche 6 du deuxième connecteur, qui constitue ici un connecteur femelle, est approchée de la platine 2, jusqu'à ce que la queue 6a soit en appui contre la rampe d'extrémité 4i du verrou. Lorsque la fiche 6 est davantage engagée dans la platine, le verrou est déplacé latéralement jusqu'à une position reculée (figures 6b et 6c) permettant l'insertion complète du deuxième connecteur pour la mise en contact des premier et deuxième connecteurs. Ce déplacement s'effectue avantageusement à l'encontre d'un effort de rappel exercé par un élément élastiquement déformable, tel qu'un ressort R intercalé entre le verrou et la platine. Comme cela sera indiqué par la suite, le ressort R est optionnel. Par ailleurs, la présence d'un ou de plusieurs détrompeur(s) réalisé(s) sous la forme d'une tige T qui s'insère dans un orifice correspondant pratiqué dans la platine, garantit l'insertion de la fiche en adéquation avec l'embase lors de son insertion dans la platine.During a first phase, the plug 6 of the second connector, which here constitutes a female connector, is approached to the plate 2, until the tail 6a bears against the end ramp 4i of the lock. When the plug 6 is more engaged in the plate, the lock is moved sideways to a retracted position ( figures 6b and 6c ) allowing the complete insertion of the second connector to bring the first and second connectors into contact. This movement is advantageously carried out against a return force exerted by an elastically deformable element, such as a spring R interposed between the lock and the plate. As will be indicated below, the spring R is optional. Furthermore, the presence of one or more keying device (s) made in the form of a rod T which fits into a corresponding hole made in the plate, guarantees the insertion of the plug in line with the base when it is inserted into the plate.

Lors du déplacement de la fiche 6 par rapport au verrou, les pions 6b s'engagent dans les fentes 4e. On notera que la position visible sur la figure 6b, dans laquelle les pions 6b se situent au niveau de l'entrée des fentes, correspond à une mise en contact des contacts mâle et femelle des connecteurs. La position 6c correspond à la position de bout de course du verrou 4 en position reculée.When the plug 6 is moved relative to the lock, the pins 6b engage in the slots 4e. Note that the position visible on the figure 6b , in which the pins 6b are located at the entry of the slots, corresponds to a contacting of the male and female contacts of the connectors. Position 6c corresponds to the end position of the latch 4 in the retracted position.

Lors de l'étape suivante (figure 6d), le verrou est avancé manuellement par action sur la queue d'extrémité 4d du verrou. Cette phase correspond au début de la phase d'assistance au raccordement des connecteurs. Lorsque le verrou est déplacé en position avancée, les pions 6b viennent en appui contre la rampe 4f des fentes 4e jusqu'à ce qu'ils atteignent le godron 4h d'extrémité (figure 6f), qui correspond à la fin de la phase d'assistance.In the next step ( figure 6d ), the lock is manually advanced by acting on the end shank 4d of the lock. This phase corresponds to the start of the assistance phase for connecting the connectors. When the bolt is moved to the advanced position, the pins 6b come to rest against the ramp 4f of the slots 4e until they reach the end gadroon 4h ( figure 6f ), which corresponds to the end of the assistance phase.

En se référant aux figures 6g et 6h, sur laquelle l'embase et la fiche ont été ôtées et sur laquelle a été représentée une vue interne d'un module de contact, on voit qu'un effort supplémentaire appliqué manuellement provoque la compression d'un matériau compressible 9 prévu entre les connecteurs de sorte que le passage des pions dans le godron 4h nécessite un effort supplémentaire aisément identifiable par l'opérateur. Ce matériau peut par exemple être obtenu par surmoulage d'un silicone.With reference to figures 6g and 6h , on which the base and the plug have been removed and on which an internal view has been shown of a contact module, it can be seen that an additional force applied manually causes the compression of a compressible material 9 provided between the connectors so that the passage of the pins in the gadroon 4h requires an additional effort easily identifiable by the operator . This material can for example be obtained by overmolding a silicone.

Dans la position illustrée à la figure 6i, les deux connecteurs sont parfaitement raccordés, le verrou étant maintenu en position avancée grâce aux pions engagés de manière stable dans les godrons.In the position shown in figure 6i , the two connectors are perfectly connected, the lock being held in the advanced position thanks to the pins engaged in a stable manner in the gadroons.

On notera également que, dans cette position, le bon raccordement des connecteurs peut être visuellement identifié grâce à un repère visuel 10 prévu sur la platine et qui n'est visible que lorsque le verrou est en position entièrement avancée.It will also be noted that, in this position, the correct connection of the connectors can be visually identified by virtue of a visual mark 10 provided on the plate and which is visible only when the lock is in the fully advanced position.

On se référera enfin aux figures 7a et 7f qui montrent que le système de raccordement selon l'invention est également adapté pour procurer une assistance au désaccouplement de connecteurs. Le désaccouplement est obtenu en déplaçant manuellement le verrou en position avancée.We will finally refer to figures 7a and 7f which show that the connection system according to the invention is also suitable for providing assistance in uncoupling connectors. Disconnection is obtained by manually moving the lock to the advanced position.

En se référant tout d'abord à la figure 7a, pour procéder à ce désaccouplement, il convient tout d'abord d'exercer un effort suffisant sur le verrou pour comprimer le matériau compressible prévu entre les connecteurs et de manière à dégager les pions des godrons 4h.Referring first to the figure 7a , to proceed with this uncoupling, it is first of all necessary to exert a sufficient force on the lock to compress the compressible material provided between the connectors and so as to release the pins from the gadroons 4h.

Il convient alors de reculer le verrou (figures 7b à 7e) pour provoquer le désaccouplement des contacts, grâce à la deuxième rampe 4g sur laquelle s'appuient les pions 6b. On notera que ce mouvement s'effectue à l'encontre de l'effort exercé par le ressort R de rappel.The lock should then be moved back ( figures 7b to 7e ) to cause the uncoupling of the contacts, thanks to the second ramp 4g on which the pins 6b rest. It will be noted that this movement takes place against the force exerted by the return spring R.

En fin de course du verrou, les contacts mâles sont entièrement extraits des contacts femelles et la fiche est en position reculée. Lorsque le verrou est entièrement déplacé en position avancée, la fiche est libre et peut être extraite manuellement.At the end of the lock stroke, the male contacts are completely extracted from the female contacts and the plug is in the retracted position. When the lock is fully moved to the advanced position, the plug is free and can be extracted manually.

On notera par ailleurs que le système qui vient d'être décrit peut en outre être doté d'un capot ou d'une coiffe en matériau électriquement conducteur (non représenté) pour constituer un blindage électromagnétique.It will also be noted that the system which has just been described can also be provided with a cover or a cap made of electrically conductive material (not shown) to constitute an electromagnetic shielding.
