- This second section hereinafter referred to as "thinned section” has a flattened shape, as the contact area, but is not used for the electrical connection.

Description
L'invention a trait au domaine général de la connectique électrique.The invention relates to the general field of electrical connection.
Elle concerne plus particulièrement une cosse pour connexion électrique, comportant une portion tubulaire, une portion plate et une portion de transition disposée entre la portion plate et la portion tubulaire, la portion plate présentant un trou de passage pour la tige d'une borne avec laquelle ladite cosse est adaptée à coopérer, ladite portion tubulaire étant prévue pour recevoir, dans son creux, l'extrémité d'un câble électrique.It relates more particularly to a lug for electrical connection, comprising a tubular portion, a flat portion and a transition portion disposed between the flat portion and the tubular portion, the flat portion having a through hole for the rod of a terminal with which said lug is adapted to cooperate, said tubular portion being adapted to receive, in its hollow, the end of an electric cable.
Ce type de cosse est courant dans de nombreuses applications électriques, par exemple pour connecter un câble à une masse métallique, la portion plate de la cosse étant vissée sur une borne saillante de cette masse métallique.This type of lug is common in many electrical applications, for example to connect a cable to a metal mass, the flat portion of the lug being screwed to a projecting terminal of this metal mass.
On connaît de telles cosses réalisées à partir d'un tube métallique dont une extrémité est aplatie par une presse.Such pods are known to be made from a metal tube, one end of which is flattened by a press.
L'extrémité aplatie de cette cosse a une fonction de plage de contact dont l'épaisseur est formée par l'assemblage de deux couches de feuilles métalliques pressées l'une contre l'autre par la presse.The flattened end of this lug has a contact pad function whose thickness is formed by the assembly of two layers of metal foils pressed against each other by the press.
Ces deux couches métalliques sont formées de la paroi du tube métallique qui a été plastiquement déformée. Le trou de passage pour la tige d'une borne est pratiqué à travers cette double couche métallique.These two metal layers are formed from the wall of the metal tube which has been plastically deformed. The passage hole for the rod of a terminal is practiced through this double metal layer.
Par ailleurs, le document
Le but de l'invention est d'améliorer ce type de cosse.The object of the invention is to improve this type of pod.
A cet effet, la cosse pour connexion électrique, comportant une portion tubulaire, une portion plate et une portion de transition disposée entre la portion plate et la portion tubulaire, la portion plate présentant un trou de passage pour la tige d'une borne avec laquelle ladite cosse est adaptée à coopérer, ladite portion tubulaire étant prévue pour recevoir, dans son creux, l'extrémité d'un câble électrique ;cette cosse étant caractérisée en ce que ladite portion plate comporte un premier tronçon dans lequel est ménagé ledit trou et un deuxième tronçon disposé entre le premier tronçon et la portion de transition, avec le deuxième tronçon qui est moins large et plus épais que le premier tronçon.For this purpose, the terminal for electrical connection, comprising a tubular portion, a flat portion and a transition portion disposed between the flat portion and the tubular portion, the flat portion having a passage hole for the stem of a terminal with which said lug is adapted to cooperate, said tubular portion being adapted to receive, in its hollow, the end of an electric cable, this lug being characterized in that said flat portion comprises a first section in which said hole is formed and a second section located between the first section and the portion of transition, with the second section being narrower and thicker than the first section.
Une telle cosse présente donc, au niveau du premier tronçon, une plage de contact reliée au deuxième tronçon, lui-même relié à la portion de transition qui présente une section permettant le passage de la forme plate du deuxième tronçon à la forme à section circulaire d'une portion de sertissage formée par la portion tubulaire de la cosse.Such a lug thus has, at the level of the first section, a contact area connected to the second section, itself connected to the transition portion which has a section allowing the passage from the flat shape of the second section to the circular section a crimping portion formed by the tubular portion of the pod.
Ce deuxième tronçon, ci-après dénommé "tronçon aminci" présente une forme aplatie, comme la plage de contact, mais n'est pas employé pour la connexion électrique.This second section, hereinafter referred to as "thinned section" has a flattened shape, as the contact area, but is not used for the electrical connection.
Cette cosse dispose ainsi d'un tronçon assurant une fonction supplémentaire par rapport à la portion de sertissage et à la plage de contact, ce tronçon aminci étant néanmoins formé de la même manière que la plage de contact, par écrasement.This pod thus has a section providing an additional function with respect to the crimping portion and the contact pad, this thinned section being nevertheless formed in the same way as the contact pad, by crushing.
Dans de nombreuses applications mettant en jeu des cosses, il est nécessaire de bloquer la rotation de la cosse lors du serrage d'un écrou sur la tige filetée d'une borne qui traverse le trou de passage de la plage de contact. Le frottement de l'écrou sur la plage de contact selon un mouvement circulaire a tendance à faire pivoter la cosse autour de la tige de la borne. Le tronçon aminci peut alors être mis à profit en coopération avec des organes de blocage latéraux écartés d'une distance inférieure à la largeur de la plage de contact et entre lesquels peut être insérée la cosse au niveau de ce tronçon aminci. Il est en effet courant, pour des raisons d'encombrement latéral notamment lorsque plusieurs cosses sont disposées en étoile sur une même borne, que l'espace disponible sur les côtés de la cosse ne permette l'agencement que de tels organes de blocage latéraux à l'écartement inférieur à la plage de contact.In many applications involving lugs, it is necessary to block the rotation of the lug when tightening a nut on the threaded rod of a terminal which passes through the hole of passage of the contact pad. The friction of the nut on the contact pad in a circular motion tends to rotate the pod around the terminal rod. The thinned section can then be used in cooperation with lateral locking members spaced apart by a distance less than the width of the contact area and between which can be inserted the terminal at this thinned section. It is indeed common, for reasons of lateral space in particular when several lugs are arranged in a star on the same terminal, that the space available on the sides of the lug allows the arrangement that such lateral locking members to the distance below the contact area.
Le tronçon aminci peut être réalisé par le même procédé d'aplatissement que pour la plage de contact, la seule différence étant qu'au niveau du tronçon aminci, l'écrasement est moins important pour conférer simultanément une épaisseur plus importante et une largeur moins importante par rapport à la plage de contact.The thinned section can be made by the same flattening process as for the contact area, the only difference being that at the level of the thinned section, the crushing is less important to simultaneously confer a greater thickness and a smaller width. relative to the contact area.
Le coût d'obtention d'une telle cosse est par conséquent sensiblement le même que celui d'une cosse de l'art antérieur, bien qu'elle présente une fonctionnalité supplémentaire.The cost of obtaining such a pod is therefore substantially the same as that of a pod of the prior art, although it has an additional functionality.
Le tronçon aminci peut de plus assurer d'autres fonctions supplémentaires, comme par exemple recevoir un marquage de la cosse. Le tronçon aminci peut en effet être gravé, imprimé ou encore recevoir un marquage adhésif ou mécaniquement maintenu, tout en ne perturbant pas le contact électrique au niveau de la plage de contact.The thinned section may furthermore provide other additional functions, such as for example receiving a marking of the terminal. The thinned section can indeed be engraved, printed or receive an adhesive marking or mechanically maintained, while not disturbing the electrical contact at the contact area.

- les valeurs des sections respectives du premier tronçon et du deuxième tronçon sont sensiblement égales ;

- le tronçon d'étanchéité comporte un joint d'étanchéité sur la surface interne de sa paroi cylindrique ;

La portion de sertissage 1 est de forme tubulaire et comporte un premier tronçon cylindrique 4 d'étanchéité ainsi qu'un deuxième tronçon cylindrique de branchement 5 coaxial et d'un diamètre inférieur au tronçon d'étanchéité 4.The crimping
La paroi tubulaire formant le tronçon d'étanchéité 4 a une épaisseur inférieure à celle du tronçon de branchement 5. La portion de sertissage 1 présente ainsi un creux cylindrique dont la forme reproduit la forme externe de la portion de sertissage 1.The tubular wall forming the
La portion plate 3 est quant à elle formée d'un premier tronçon plat formant une plage de contact 6 et d'un deuxième tronçon plat formant un tronçon aminci 7 dans le sens de la largeur et présentant une épaisseur supérieure à l'épaisseur de la plage de contact 6.The
La portion de transition 2 a une forme caractéristique permettant de relier la forme plate du tronçon aminci 7 à la forme cylindrique du tronçon de branchement 5 de la portion de sertissage 1.The
La portion de sertissage 1 est ainsi adaptée à recevoir un câble électrique dénudé dont l'extrémité nue du conducteur est insérée dans le tronçon de branchement 5 tandis que le reste du câble, muni de son isolant, s'étend dans le tronçon d'étanchéité 4. Lors du sertissage, le tronçon de branchement 5 est comprimé sur le conducteur pour permettre le contact électrique tandis que le tronçon d'étanchéité 4 est comprimé sur l'isolant du câble de manière que l'assemblage du tronçon d'étanchéité 4 et du câble soit étanche.The
En variante, le tronçon d'étanchéité 4 peut recevoir un joint torique disposé sur sa paroi interne de sorte à renforcer l'étanchéité de l'assemblage du tronçon d'étanchéité 4 et du câble électrique connecté à la cosse.Alternatively, the
En ce qui concerne la portion plate 3, celle-ci est constituée de deux couches de matériau pressées l'une contre l'autre. Au niveau de la plage de contact 6, les deux couches de matériau sont comprimées plus fortement qu'au niveau du tronçon aminci 7, ce qui explique la différence d'épaisseur entre ces deux tronçons 5, 7.As regards the

Ce tube métallique est tout d'abord déformé plastiquement à l'une de ses extrémités à l'aide d'une broche insérée dans le tube, ce qui permet de former le tronçon d'étanchéité 4 qui présente un diamètre supérieur au tronçon de branchement 5. La portion de sertissage 1 est ainsi dès lors réalisée.This metal tube is first of all plastically deformed at one of its ends by means of a pin inserted in the tube, which makes it possible to form the
La cosse est ensuite disposée dans une presse et une matrice vient aplatir la zone du cylindre métallique qui correspond à la portion plate 3. La matrice employée à cet effet comporte deux mâchoires adaptées à écraser simultanément le tube métallique pour que la portion plate 3 soit disposée le long de l'axe longitudinal de la portion de sertissage 1 de manière que la cosse soit symétrique par rapport au plan dans lequel s'étend la portion plate 3 (voir
Les deux mâchoires de la matrice sont conformées de manière à présenter une première surface plane destinée à former la plage de contact 6 et à présenter une deuxième surface plane en retrait par rapport à la précédente, c'est-à-dire qu'un dénivelé est présent entre ces deux surfaces planes de chaque mâchoire de la matrice, pour former le tronçon aminci 7.The two jaws of the matrix are shaped so as to have a first planar surface intended to form the
Lors de l'écrasement de cette portion du tube métallique initial, le tronçon correspondant à la plage de contact 6 subit de ce fait un aplatissement plus important que le tronçon aminci 7, ce qui conduit à une plage de contact 6 plus fine mais plus large que le tronçon aminci 7.During the crushing of this portion of the initial metal tube, the portion corresponding to the

Des variantes de réalisation du dispositif peuvent être envisagées sans pour autant sortir du cadre de l'invention. Notamment, l'agencement de la portion plate 3 par rapport à la portion de sertissage 1 peut être différent, par exemple asymétrique.Alternative embodiments of the device can be envisaged without departing from the scope of the invention.
