Description

La présente invention se rapporte à des dispositifs de shuntage de plusieurs organes de contacts électriques.The present invention relates to devices for shunting multiple contact members electric.

L'invention vise des dispositifs comprenant un élément de boítier pourvu d'une série de canaux destinés à recevoir, chacun, un organe de contact électrique femelle serti à l'extrémité d'un conducteur électrique, chaque canal s'ouvrant sur une languette mâle reliée à une barrette de shuntage.The invention relates to devices comprising a housing element provided with a series of channels intended to each receive an electrical contact member female crimped to the end of a conductor electric, each channel opening on a tab male connected to a shunt bar.

Voir par ex. le document US-A-5 201 667.See e.g. US-A-5,201,667.

Afin d'éviter toute souillure qui nuirait à un bon contact électrique, chaque canal, du côté de l'introduction de l'organe de contact électrique femelle, présente un logement rempli d'un gel d'étanchéïté, de préférence un gel autocicatrisant afin, qu'une fois que l'organe de contact électrique a traversé le gel, celui-ci se referme autour du conducteur électrique assurant ainsi l'étanchéïté.In order to avoid any contamination which would harm to good electrical contact, each channel, on the side of the introduction of the electrical contact member female, has a housing filled with a gel sealing, preferably a self-healing gel so that once the electrical contact member has passed through the gel, it closes around the electrical conductor thus ensuring sealing.

Un des inconvénients de cette disposition est qu'il est difficile de vérifier si les organes de contacts électriques femelles sont parfaitement mis en place et si la liaison électrique est assurée.One of the drawbacks of this arrangement is that it is difficult to verify whether the organs of female electrical contacts are perfectly installed and if the electrical connection is ensured.

L'un des buts de la présente invention est de remédier à ces inconvénients.One of the aims of the present invention is to remedy these drawbacks.

Les perfectionnements, selon l'invention, visent des dispositifs de shuntage de plusieurs organes de contacts électriques du type comprenant un élément de boítier transparent présentant une série de canaux destinés, chacun, à recevoir un organe de contact électrique femelle engagé dans une extrémité libre desdits canaux, chaque organe étant serti, à une extrémité, d'un conducteur électrique, l'élément de boítier présentant, du côté opposé à l'extrémité libre des canaux, une empreinte dans laquelle est logée une barrette de shuntage comportant une série de languettes s'étendant dans les canaux et destinées à s'insérer dans les organes de contacts électriques femelles, les canaux étant, au voisinage de leur extrémité libre, remplis d'un gel d'étanchéité, lesdits perfectionnements étant caractérisés en ce que l'élément de boítier comporte, au droit de chaque canal dans la partie contenant le gel d'étanchéïté, un trou borgne.Improvements according to the invention, target multi-organ shunting devices of electrical contacts of the type comprising an element of transparent case presenting a series of channels each intended to receive a contact member electric female engaged in a free end said channels, each member being crimped at one end, of an electrical conductor, the housing element having, on the side opposite the free end channels, a footprint in which is housed a shunt bar with a series of tabs extending into the channels and intended to be inserted in the female electrical contact members, the channels being, in the vicinity of their free end, filled with a sealing gel, said improvements being characterized in that the housing element comprises, to the right of each channel in the part containing sealing gel, a blind hole.

Grâce à cette disposition, on peut engager dans le trou borgne et à travers le gel d'étanchéité et l'isolant du conducteur, une pointe d'un testeur afin de vérifier que les organes de contacts électriques femelles sont convenablement montés dans l'élément de boítier.Thanks to this arrangement, we can hire in the blind hole and through the sealing gel and conductor insulation, a tip of a tester in order to verify that the electrical contact members females are properly mounted in the element of housing.

Suivant une autre caractéristique, chaque conducteur électrique, dans sa partie destinée à venir au droit du trou borgne, comporte une marque. Ainsi on peut également avoir une vérification visuelle du bon montage des organes de contacts électriques femelles.According to another characteristic, each electrical conductor, in its part intended to come to the right of the blind hole, has a mark. So we can also have a visual check of the correct assembly of female electrical contact members.

Suivant une caractéristique constructive, l'élément de boítier comporte, au droit de chaque canal, un bossage destiné à coopérer avec une ouverture de l'organe de contact électrique femelle correspondant. Ainsi, on assure un verrouillage des organes de contacts électriques femelles dans les canaux. According to a constructive characteristic, the housing element comprises, at the right of each channel, a boss intended to cooperate with an opening of the corresponding female electrical contact member. Thus, it ensures a locking of the contact members electrical cables in the channels.

Suivant encore une autre caractéristique, chaque languette présente une lumière et chaque organe de contact électrique femelle une barrette de retenue destinée à s'engager dans ladite lumière. Ainsi, on réalise un verrouillage indémontable des organes de contacts électriques femelles dans les canaux.According to yet another characteristic, each tab has a light and each organ female electrical contact a retaining bar intended to engage in said light. So, a non-removable locking of the members is carried out of female electrical contacts in the channels.

Enfin, suivant un détail constructif, la barrette de retenue et l'ouverture sont réalisées sur une même paroi de l'organe de contact électrique femelle. Finally, following a constructive detail, the retaining bar and opening are made on the same wall of the female electrical contact member.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described. in more detail with reference to an embodiment particular given as an example only and shown in the accompanying drawings, in which:

Figure 1 est une vue en perspective d'un dispositif de shuntage, selon l'invention.Figure 1 is a perspective view of a shunting device according to the invention.

Figure 2 est une vue en coupe longitudinale passant par un canal du boítier.Figure 2 is a longitudinal sectional view passing through a channel of the housing.

Le dispositif représenté aux figures comprend un élément de boítier 1 formé de deux demi-coquilles 2 et 3 collées ou soudées par leur bord, la demi-coquille 2 présentant une empreinte 4 dans laquelle est montée une barrette de shuntage 5 présentant une série de languettes mâles 6 engagées dans des canaux 7 et comportant, chacune, une lumière 8.The device shown in the figures comprises a housing element 1 formed of two half-shells 2 and 3 glued or welded by their edges, the half-shell 2 having an imprint 4 in which is mounted a shunt bar 5 having a series of male tabs 6 engaged in channels 7 and each having a light 8.

La demi-coquille 3 est complémentaire de la demi-coquille 2 et présente une série de logements 9 correspondant, chacun, à un canal 7, chaque logement présentant un trou borgne 10.The half-shell 3 is complementary to the half-shell 2 and has a series of housings 9 corresponding, each, to a channel 7, each housing with a blind hole 10.

Chaque canal 7 est destiné à recevoir un organe de contact électrique femelle 12 à section rectangulaire avec une âme 13, deux parois latérales 14 avec des prolongements et pliées en regard l'une de l'autre pour former une paroi de plafond 15 dans laquelle est ménagée une ouverture 16 et est découpée une barrette de retenue 17.Each channel 7 is intended to receive a female electrical contact member 12 with rectangular section with a core 13, two side walls 14 with extensions and folded facing each other to form a ceiling wall 15 in which is formed an opening 16 and a strip is cut out restraint 17.

Chaque organe de contact électrique femelle 12 présente des pattes 20 et 21 pour le sertissage d'un conducteur 22 qui comporte une marque de couleur 23. Each female electrical contact member 12 has tabs 20 and 21 for crimping of a conductor 22 which has a color mark 23.

La demi-coquille 3 comporte, au droit de chaque canal 7, un bossage 25.The half-shell 3 comprises, at the right of each channel 7, a boss 25.

Les extrémités des canaux 7 opposées à l'empreinte 4 et les logements 10 sont remplis d'un gel d'étanchéité 26 d'un type autocicatrisant, c'est-à-dire d'un type susceptible d'être traversé par un organe 12 et de se refermer autour du conducteur électrique 22.The ends of the channels 7 opposite footprint 4 and housings 10 are filled with sealing gel 26 of a self-healing type, that is to say of a type liable to be crossed by a member 12 and close around the conductor electric 22.

Un tel gel d'étanchéité est translucide et la demi-coquille 1 est transparente.Such sealing gel is translucent and the half-shell 1 is transparent.

Lorsqu'on met en place un organe de contact électrique 12, celui-ci est engagé par l'extrémité libre d'un canal 7 à travers le gel 26 puis est poussé afin que le bossage 25 vienne coopérer avec l'ouverture 16 qui assure le blocage dudit organe 12 dans le canal. Dans cette position, la languette correspondante 6 est engagée dans l'organe de contact électrique 12 et la barrette de retenue 17 est insérée dans la lumière 8, ce qui rend l'assemblage des organes 6 et 12 pratiquement indémontable.When setting up a contact body electric 12, it is engaged by the end free of a channel 7 through gel 26 then is pushed so that the boss 25 comes to cooperate with the opening 16 which blocks said member 12 in the canal. In this position, the corresponding tab 6 is engaged in the contact member 12 and the retaining bar 17 is inserted in light 8, which makes the assembly of organs 6 and 12 practically non-removable.

A travers le trou borgne 10, on peut vérifier visuellement la bonne position de l'organe 12, la marque 23 étant imprimée en un point du conducteur devant se situer en regard du trou borgne 10 si l'assemblage de la languette 6 et de l'organe 12 est correct.Through the blind hole 10, we can check visually the correct position of the member 12, mark 23 being printed at a point of the conductor in front of the blind hole 10 if the assembly of the tongue 6 and of the member 12 is correct.

On peut également vérifier que la liaison électrique est réalisée en engageant, dans les trous borgnes 10, des pointes de testeur qui traversent le fond desdits trous, le gel et l'isolant pour porter contre l'âme conductrice. Après cette vérification, le gel 26 assure, en se cicatrisant, une bonne isolation électrique.We can also verify that the connection electric is achieved by engaging, in the holes blind 10, tester points crossing the bottom of said holes, gel and insulation to wear against the conductive core. After this verification, gel 26 ensures, by healing, good insulation electric.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention, comme définie dans les revendications qui suivent.Of course, the invention is not limited to the embodiment which has just been described to be present. We can make many modifications detail without going beyond the framework of the invention, as defined in the claims which follow.
