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 several electrical contact members.

L'invention vise des dispositifs comprenant un élément de boîtier 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 a female electrical contact member crimped at the end of an electrical conductor, each channel opening onto a male tab. connected to a shunt bar.

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 interfere with good electrical contact, each channel, on the side of the introduction of the female electrical contact member, has a housing filled with a sealing gel, preferably a self-healing gel so , that once the electrical contact member has passed through the gel, the latter closes around the electrical conductor thus ensuring the seal.

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 female electrical contact members are perfectly in place and whether 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 boîtier transparent présentant une série de canaux destinés, chacun, à recevoir un organe de contact électrique femelle engagé par une extrémité libre desdits canaux, chaque organe étant serti, à une extrémité, d'un conducteur électrique, l'élément de boîtier 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 boîtier comporte, au droit de chaque canal dans la partie contenant le gel d'étanchéïté, un trou borgne.The improvements according to the invention relate to devices for shunting several electrical contact members of the type comprising a transparent housing element having a series of channels each intended to receive a female electrical contact member engaged by a free end of said channels, each member being crimped at one end to an electrical conductor, the housing element having, on the side opposite the end free of the channels, an imprint in which is housed a shunt bar comprising a series of tabs extending in 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, at the level of each channel in the part containing the 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 boîtier.Thanks to this arrangement, it is possible to engage in the blind hole and through the sealing gel and the insulator of the conductor, a tip of a tester in order to verify that the female electrical contact members are properly mounted in the element. case.

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 in line with the blind hole, has a mark. Thus one can also have a visual verification of the correct mounting of the female electrical contact members.

Suivant une caractéristique constructive, l'élément de boîtier 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 level 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 female electrical contact members 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 slot and each female electrical contact member a retaining strip intended to engage in said slot. Thus, a non-removable locking of the female electrical contact members in the channels is carried out.

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, according to a constructive detail, the retaining bar and the opening are produced 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 a particular embodiment given by way of 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 boîtier.Figure 2 is a longitudinal sectional view passing through a channel of the housing.

Le dispositif représenté aux figures comprend un élément de boîtier 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 edge, the half-shell 2 having an imprint 4 in which is mounted a shunt bar 5 having a series of tabs males 6 engaged in channels 7 and each having a lumen 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 each corresponding to a channel 7, each housing having 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 of rectangular section with a core 13, two side walls 14 with extensions and folded opposite one another to form a ceiling wall 15 in which is formed an opening 16 and a retaining bar 17 is cut out.

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 a conductor 22 which has a colored mark 23.

La demi-coquille 3 comporte, au droit de chaque canal 7, un bossage 25.The half-shell 3 comprises, at the level 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 the impression 4 and the housings 10 are filled with a sealing gel 26 of a self-healing type, that is to say of a type capable of being crossed by a member. 12 and close around the electrical conductor 22.

Un tel gel d'étanchéité est translucide et la demi-coquille 1 est transparente.Such a 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 an electrical contact member 12 is put in place, it is engaged by the free end of a channel 7 through the gel 26 and is then pushed so that the boss 25 comes to cooperate with the opening 16 which ensures blocking said member 12 in the channel. In this position, the corresponding tongue 6 is engaged in the electrical contact member 12 and the retaining bar 17 is inserted in the slot 8, which makes the assembly of the members 6 and 12 practically impossible to dismantle.

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, it is possible to visually check the correct position of the member 12, the mark 23 being printed at a point on the conductor which must be located opposite the blind hole 10 if the assembly of the tongue 6 and the organ 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.It can also be verified that the electrical connection is made by engaging, in the blind holes 10, tester tips which pass through the bottom of said holes, the gel and the insulation to bear against the conductive core. After this verification, gel 26 ensures, by healing, good electrical insulation.

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.Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the invention.
