Description

La présente invention se rapporte à un module électrique de connexion de masse comprenant un agencement de contact définissant un shunt et une pluralité de contacts mâles destinés à recevoir des contacts femelles fixés aux extrémités de conducteurs à connecter à la masse, des moyens de rétention des contacts femelles sur les contacts mâles, des moyens pour fixer le module sur un support et établir un connexion électrique entre ledit agencement de contact et ledit support, et des moyens isolants pour confiner les contacts dans le module.The present invention relates to an electrical module for ground connection comprising a contact arrangement defining a shunt and a plurality of male contacts intended to receive contacts females attached to the ends of conductors to be connected to ground, means for retaining female contacts on male contacts, means for fixing the module on a support and establishing a connection electric between said contact arrangement and said support, and insulating means for confining the contacts in the module.

Sur un module connu de ce type, l'agencement de contact se compose d'une plaque métallique circulaire sur laquelle une multitude de contacts mâles individuels en forme de broches sont fixés sur un cercle. Les moyens de rétention sont constitués par une pluralité de douilles à ailettes métalliques rapportées dans un boítier en matière isolante qui vient porter sur la plaque métallique en entourant les contacts mâles. Les pièces de contact mâles sont entourées de manchons qui servent d'appui aux douilles à ailettes. Un élément supplémentaire est prévu pour assurer l'assemblage du boítier avec la plaque métallique.On a known module of this type, the contact arrangement is consists of a circular metal plate on which a multitude of Individual pin-shaped male contacts are attached to a circle. The retention means consist of a plurality of sockets with metal fins attached in a housing made of insulating material which comes to bear on the metal plate by surrounding the male contacts. The male contact parts are surrounded by sleeves which serve as support with winged sockets. An additional element is provided to ensure assembly of the housing with the metal plate.

Le principal inconvénient de ce module connu consiste dans son coût élevé, dû notamment au grand nombre de ses parties constitutives (frais de fabrication élevés, assemblage long et onéreux).The main drawback of this known module consists in its high cost, due in particular to the large number of its constituent parts (high manufacturing costs, long and expensive assembly).

La présente invention vise un module électrique de connexion de masse qui se distingue en particulier par un nombre très réduit de parties constitutives qui puissent être assemblées de façon simple et rapide, à un coût réduit.The present invention relates to an electrical connection module for mass which is distinguished in particular by a very small number of parts which can be assembled simply and quickly, to a reduced cost.

Le module électrique de connexion de masse, objet de l'invention, comprend un agencement de contact constitué par un ensemble shunt-contacts mâles monopièce.The electrical module for ground connection, object of the invention comprises a contact arrangement consisting of a one-piece male shunt-contact assembly.

De préférence, l'ensemble shunt-contacts mâles est formé par filage, par exemple en aluminium ou alliage d'aluminium.Preferably, the male shunt-contact assembly is formed by wiring, for example aluminum or aluminum alloy.

Il s'est avéré de façon surprenante qu'il était possible de réaliser d'une seule pièce par filage un shunt circulaire portant sur une face une multitude de contacts mâles parfaitement dégagés, par exemple douze broches de contact d'un diamètre inférieur à 1 mm, réparties sur un cercle de par exemple 15 mm.It turned out surprisingly that it was possible to achieve in one piece by spinning a circular shunt carrying on one side a multitude of perfectly cleared male contacts, for example twelve contact pins with a diameter of less than 1 mm, distributed in a circle of for example 15 mm.

Pour réduire encore le nombre des parties constitutives et diminuer le coût d'assemblage du module conforme à l'invention, il peut être avantageux, pour la rétention des contacts femelles dans le module, d'utiliser non pas des douilles à ailettes métalliques rapportées dans le boítier, mais des ailettes de rétention formées d'une seule pièce avec le boítier constitué de préférence en matière plastique.To further reduce the number of constituent parts and reduce the assembly cost of the module according to the invention, it can be advantageous, for the retention of female contacts in the module, not to use metal finned sleeves added in the housing, but retention fins formed in one piece with the housing preferably made of plastic.

Dans le même but, il est avantageux, suivant un mode de réalisation de l'invention, que le boítier comporte des languettes d'encliquetage coopérant avec l'ensemble shunt-contacts mâles, de préférence des languettes d'encliquetage coopérant extérieurement avec ledit ensemble.For the same purpose, it is advantageous, according to a method of embodiment of the invention, that the housing has tabs latching cooperating with the male shunt-contact assembly, preferably snap tabs cooperating externally with said set.

Pour permettre le moulage des ailettes de rétention d'une seule pièce avec le boítier, il est nécessaire de prévoir des dégagements dans les trous de passage du boítier, entre les ailettes de rétention et le côté du boítier coopérant avec l'ensemble shunt-contacts mâles. Ces dégagements peuvent être obtenus par le fait que lesdites parties des trous de passage présentent un diamètre supérieur au diamètre des contacts femelles destinées à être retenus par les ailettes de rétention. Toutefois, dans ce cas, les contacts femelles sont mal guidés dans les trous de passage du boítier.To allow the molding of the retention fins of a single room with the housing, it is necessary to provide clearances in the through holes of the housing, between the retention fins and the side of the housing cooperating with the male shunt-contact assembly. These clearances can be obtained by the fact that said parts of the through holes have a diameter greater than the diameter of the female contacts intended to be retained by the retention fins. However, in this case, the female contacts are badly guided in the holes of passage of the housing.

C'est pourquoi, suivant un mode de réalisation préféré de l'invention, les trous de passage du boítier comportent, dans la zone située entre les ailettes de rétention et ladite face du boítier, des nervures de guidage pour les contacts femelles, ces nervures faisant saillie radialement vers l'intérieur.This is why, according to a preferred embodiment of the invention, the through holes of the housing include, in the area located between the retention fins and said face of the housing, ribs of guide for the female contacts, these ribs projecting radially inward.

De préférence, les ailettes de rétention sont réparties à la manière de pétales sur le pourtour d'un trou de passage et les nervures de guidage sont décalées angulairement par rapport aux ailettes de rétention, de préférence en étant situées angulairement dans une position intercalaire entre chaque fois deux ailettes de rétention voisines.Preferably, the retention fins are distributed at the way of petals around the edge of a through hole and the ribs of guidance are angularly offset with respect to the retention fins, preferably by being located angularly in a position insert between each two adjacent retention fins.

En se référant à la figure unique du dessin annexé, on va décrire ci-après plus en détail un mode de réalisation illustratif et non limitatif d'un module de masse conforme à l'invention.Referring to the single figure of the accompanying drawing, we will describe below in more detail an illustrative and nonlimiting embodiment a mass module according to the invention.

La figure unique du dessin est une coupe axiale du module assemblé.The single figure in the drawing is an axial section of the module assembled.

Le module électrique 1 de connexion de masse tel qu'illustré par la figure unique du dessin, est destiné à permettre la connexion à la masse d'une pluralité de conducteurs non représentés, par exemple de douze conducteurs. Chacun de ces conducteurs comporte à son extrémité un embout de contact femelle fixé par sertissage au conducteur et présentant un épaulement circulaire de rétention. De tels embouts de contact femelles sont bien connus et sont couramment utilisés, par exemple, dans le domaine aéronautique.The electrical module 1 for ground connection as illustrated by the single figure of the drawing, is intended to allow connection to earth a plurality of unrepresented conductors, for example twelve conductors. Each of these conductors has at its end a female contact tip fixed by crimping to the conductor and having a circular retention shoulder. Such female contact tips are well known and are commonly used, for example, in the aeronautics.

Le module 1 comprend, pour connecter à la masse les embouts des conducteurs, un ensemble de contact 2 constitué par une plaque-shunt 3 circulaire, portant sur une face une pluralité de contacts mâles 4 en forme de broches, par exemple douze contacts 4 répartis sur un cercle. Les contacts 4 et la plaque 3 sont réalisés d'une seule pièce, de préférence par filage en aluminium ou alliage d'aluminium. A titre d'exemple, la plaque 3 peut présenter un diamètre de l'ordre de 15 mm et chaque contact 4 peut présenter un diamètre de l'ordre de 0,8 mm sur une longueur de l'ordre de 2,4 mm. La plaque 3 est percée d'un trou central 5 pour le passage de la tige 7a d'une vis 6 dont la tête 7b porte sur la face supérieure de la plaque 3 par l'intermédiaire d'une rondelle 8 et qui sert à la fixation de la plaque 3, donc du module 1, sur une structure de support non représentée formant masse.Module 1 includes, for grounding the end caps conductors, a contact assembly 2 consisting of a shunt plate 3 circular, carrying on a face a plurality of male contacts 4 in in the form of pins, for example twelve contacts 4 distributed on a circle. The contacts 4 and plate 3 are made in one piece, preferably by aluminum or aluminum alloy wiring. As an example, plate 3 can have a diameter of the order of 15 mm and each contact 4 can have a diameter of the order of 0.8 mm over a length of the order of 2.4 mm. The plate 3 is pierced with a central hole 5 for the passage of the rod 7a with a screw 6, the head 7b of which bears on the upper face of the plate 3 by through a washer 8 and which is used for fixing the plate 3, therefore of module 1, on a support structure, not shown, forming a mass.

En vue du confinement des contacts et en vue de la rétention des contacts femelles dans le module 1, un boítier 9 est rapporté sur l'ensemle de contact 2, sur la face supérieure de la plaque 3. Le boítier 9 de forme générale cylindrique, présente un trou central 10 dont le diamètre est légèrement supérieur au diamètre de la tête 7b de la vis 6, sauf à l'endroit d'un rebord intérieur 11 prévu au voisinage de l'extrémité supérieure du boítier 9. Le boítier 9 comporte extérieurement, à son extrémité inférieure, plusieurs languettes d'encliquetage 12 qui coopèrent avec l'extérieur de la plaque 3, lors de l'emboítement du boítier 9 sur l'ensemble de contact 2, après engagement de la tige 7a de la vis 6 depuis le haut dans le trou 5 de la plaque 3. Après encliquetage du boítier 9 sur l'ensemble de contact 2, la tête 7a de la vis 6 est ainsi maintenue prisonnière dans le module, grâce au rebord intérieur 11 du boítier 9.For the containment of contacts and for the retention of female contacts in module 1, a housing 9 is attached to the assembly contact 2, on the upper face of the plate 3. The housing 9 of form general cylindrical, has a central hole 10 whose diameter is slightly greater than the diameter of the head 7b of the screw 6, except at the place an inner rim 11 provided in the vicinity of the upper end of the box 9. The box 9 has externally, at its end lower, several locking tabs 12 which cooperate with the outside of the plate 3, when the housing 9 fits into the assembly contact 2, after engagement of the rod 7a of the screw 6 from the top in the hole 5 of the plate 3. After snap-on of the housing 9 on the assembly of contact 2, the head 7a of the screw 6 is thus held captive in the module, thanks to the inner rim 11 of the housing 9.

Le boítier 9 présente, à l'endroit de chaque contact mâle 4 de l'ensemble de contact 2, un trou de passage 13 s'étendant à travers le boítier 9 sur toute la hauteur de ce dernier. A la partie supérieure du boítier 9, en l'occurence à peu près à la hauteur du rebord intérieur 1 1, chaque trou de passage 13 renferme plusieurs ailettes de rétention 14. Dans l'exemple représenté, les ailettes de rétention 14 de chaque trou de passage 13 sont au nombre de trois, en étant angulairement réparties uniformément sur le pourtour, à la manière de pétales. Les ailettes 14 de chaque trou de passage 13 convergent vers le bas en direction des contacts mâles 4.The housing 9 has, at the location of each male contact 4 of contact assembly 2, a through hole 13 extending through the housing 9 over the entire height of the latter. At the top of the case 9, in this case approximately at the height of the internal edge 1 1, each hole passage 13 contains several retention fins 14. In the example shown, the retention fins 14 of each through hole 13 are three in number, being angularly evenly distributed over the around, like petals. The fins 14 of each through hole 13 converge downwards towards the male contacts 4.

En dessous des ailettes de rétention 14, chaque trou de passage 13 renferme plusieurs nervures longitudinales 15. Dans l'exemple représenté, les nervures 15 sont au nombre de trois et sont réparties uniformément sur le pourtour, en étant angulairement décalées par rapport aux ailettes 14 de manière à être situées angulairement en position intercalaire par rapport aux ailettes 14. Les nervures 15 assurent le guidage des contacts femelles (embouts) des conducteurs en dessous des ailettes de rétention 14 et grâce à leur position angulaire décalée par rapport aux ailettes 14, elles ne gênent pas le moulage et le démoulage des ailettes 14. Néanmoins, elles assurent le guidage et le centrage des contacts femelles, de manière que ces contacts viennent s'emboíter sans problème sur les contacts mâles 4 de l'ensemble de contact 2, lors de leur insertion dans les trous de passage 13 du boítier 9.Below the retention fins 14, each passage hole 13 contains several longitudinal ribs 15. In the example shown, the ribs 15 are three in number and are distributed uniformly around the perimeter, being angularly offset from to the fins 14 so as to be located angularly in position interlayer with respect to the fins 14. The ribs 15 provide the guiding the female contacts (ferrules) of the conductors below the retention fins 14 and thanks to their angular position offset by compared to the fins 14, they do not interfere with the molding and demolding of the fins 14. Nevertheless, they provide guidance and centering of the female contacts, so that these contacts fit together without problem on the male contacts 4 of the contact assembly 2, when they insertion into the through holes 13 of the housing 9.

Grâce à ces caractéristiques, le boítier 9 peut être moulé d'une seule pièce en matière plastique, non seulement avec les languettes d'encliquetage 12, mais également avec les ailettes de rétention 14.Thanks to these characteristics, the housing 9 can be molded from a single piece of plastic, not only with the tabs latching 12, but also with the retention fins 14.

Le module de connexion tel que représenté et décrit se compose donc d'un nombre très réduit de parties constitutives, à savoir d'un ensemble de contact 2 monopièce, d'un boítier 9 monopièce, d'une vis 6 et d'une rondelle 8 (ainsi qu'éventuellement d'un joint torique 16 clipsé sur un épaulement inférieur de la plaque 3), l'assemblage de ces cinq parties étant particulièrement simple dans la mesure où il n'implique aucune opération d'usinage ou de formage. En comparaison, un module similaire selon la technique antérieure comprend, pour douze contacts, trente et une parties constitutives, à savoir un boítier, une plaque-shunt, douze contacts mâles en forme de broches rapportés et fixés par sertissage sur cette plaque, douze douilles de rétention à ailettes, douze manchons entourant les contacts mâles pour servir d'appui aux manchons de rétention, un manchon d'assemblage du boítier avec la plaque-shunt et un joint moulé sous la plaque-shunt.The connection module as shown and described consists of therefore of a very reduced number of constituent parts, namely of a contact assembly 2 one-piece, a housing 9 one-piece, a screw 6 and a washer 8 (and possibly an O-ring 16 clipped onto a lower shoulder of the plate 3), the assembly of these five parts being particularly simple insofar as it does not involve any machining or forming operation. In comparison, a similar module according to the prior art comprises, for twelve contacts, thirty-one component parts, namely a housing, a shunt plate, twelve male contacts in the form of pins attached and fixed by crimping on this plate, twelve retention sockets with fins, twelve sleeves surrounding the male contacts to serve as support for the retention, a housing assembly sleeve with the shunt plate and a seal molded under the shunt plate.

Il serait également possible, dans le cadre de l'invention, de réaliser la plaque-shunt 3 non pas par filage en aluminium ou alliage d'aluminium, mais par exemple par matriçage et/ou en d'autres métaux ou alliages, par exemple à base de cuivre. Le filage présente cependant l'avantage de conduire à des contacts mâles 4 parfaitement dégagés, ce qui n'est pas toujours le cas avec d'autres procédés.It would also be possible, within the framework of the invention, to make plate-shunt 3 not by aluminum or alloy wiring aluminum, but for example by stamping and / or other metals or alloys, for example based on copper. The wiring presents however the advantage of leading to perfectly cleared male contacts 4, which is not always the case with other methods.
