Description

Douille de contact à languettes de verrouillageContact sleeve with locking tabs
L'invention est relative à une douille de contact à languettes élastiques de verrouillage destinées à retenir la douille prisonnière dans un logement de support isolant. De telles douilles sont habituellement constituées par une virole obtenue par roulage d'un flan métallique et présentant une jointure longitudinale. Ces douilles comportent ainsi d'un bord à l'autre de la jointure un arrangement de languettes ou bandes de contact et de languettes de verrouillage découpées dans la virole. Mais les découpes sont telles que les languettes ou bandes de contact et les languettes de verrouillage sont, soit disposées successivement le long de la douille, ce qui permet de leur conférer une bonne tenue mécanique mais impose un encombrement important, soit disposées côte à côte au mime niveau, ce qui donne un encombrement réduit, mais s'accompagne d'une tenue mécanique précaire. En effet, dans ce dernier cas on constate un déséquilibrage des efforts longitudinaux auxquels la douille peut être soumise, ce qui entraîne un gauchissement des pattes de verrouillage qui travaillent alors dans de mauvaises conditions. L'invention a pour but une douille de contact obtenue par roulage, ayant un encombrement réduit, mais offrant une bonne tenue mécanique en présence des efforts longitudinaux qu'elle est appelée à subir. L'invention a pour objet une douille de contact à languettes de verrouillage destinées à la retenir dans le logement d'un support isolant, ladite douille comprenant une virole formée par roulage d'un flan métallique et présentant longitudinalement une jointure, à une extrémité un collet destiné à être relié à un conducteur électrique et à l'extrémité opposée une entrée pour fiche de contact, caractérisée en ce qu'elle comporte deux languettes de verrouillage élastique découpées le long de la virole, encadrées par des fentes de découpage, lesdites languettes étant attenantes à l'entrée et légèrement écartées du collet, et étant séparées entre elles, d'un côté intérieur par une bande de contact interne reliant le collet à l'entrée, et de l'autre côté extérieur pour l'une des languettes de verrouillage par une bande de contact externe reliant le collet à l'entrée et pour l'autre languette de verrouillage par une languette de contact externe attenant au collet et séparée par une découpe de l'entrée, la bande dé contact externe et la languette externe étant disposées en regard de la jointure de la virole.The invention relates to a contact socket with elastic locking tabs intended to retain the captive socket in an insulating support housing. Such sockets are usually formed by a ferrule obtained by rolling a metal blank and having a longitudinal joint. These sockets thus comprise, from one edge to the other of the joint, an arrangement of contact tongues or strips and of locking tongues cut from the ferrule. But the cutouts are such that the contact tabs or strips and the locking tabs are either arranged successively along the bushing, which makes it possible to give them good mechanical strength but requires considerable space, or are placed side by side at mime level, which gives a reduced bulk, but is accompanied by precarious mechanical strength. Indeed, in the latter case there is an imbalance of the longitudinal forces to which the sleeve can be subjected, which results in warping of the locking tabs which then work in poor conditions. The object of the invention is to provide a contact sleeve obtained by rolling, having a reduced bulk, but offering good mechanical strength in the presence of the longitudinal forces which it is called upon to undergo. The subject of the invention is a contact socket with locking tabs intended to retain it in the housing of an insulating support, said socket comprising a ferrule formed by rolling a metal blank and having a joint longitudinally, at one end a collar intended to be connected to an electrical conductor and at the opposite end an entry for a contact plug, characterized in that it comprises two elastic locking tabs cut out along the shell, framed by cutting slots, said tabs being adjacent to the entrance and slightly apart from the collar, and being separated from each other, on an inner side by an internal contact strip connecting the collar to the entrance, and on the other outer side for one of the tabs locking by an external contact strip connecting the collar to the inlet and for the other locking tab by a tab external contact adjoining the collar and separated by a cutout from the inlet, the external contact strip and the external tongue being arranged facing the joint of the ferrule.
Selon une caractéristique, d'une part la bande de contact interne est sensiblement disposée diamétralement à l'opposé de la jointure de la languette externe et de la bande de contact externe et d'autre part les languettes de verrouillage sont sensiblement disposées en opposition selon un plan diamétral.According to one characteristic, on the one hand the internal contact strip is substantially arranged diametrically opposite the joint of the external tongue and the external contact strip and on the other hand the locking tabs are substantially arranged in opposition according to a diametral plane.
Selon une autre caractéristique, l'entrée comporte un chanfrein, qui peut être obtenu par frappe.According to another characteristic, the entry comprises a chamfer, which can be obtained by striking.
Les caractéristiques et avantages de l'invention ressortiront de la description d'un mode de réalisation, donné ci-après à titre d'exemple et illustré dans les figures.The characteristics and advantages of the invention will emerge from the description of an embodiment, given below by way of example and illustrated in the figures.
La figure 1 est une vue en perspective de la douille selon l'invention.Figure 1 is a perspective view of the socket according to the invention.
La figure 2 représente une vue développée de la douille, constituée par le flan découpé à partir de laquelle elle est obtenue. Dans les figures on a désigné par 1 la virole de la douille dont les bords 11 et 12 donnent naissance à la jointure longitudinale 10 visible sur la figure 1. La virole comporte à la partie inférieure une entrée 2 destinée à l'enfichage d'une broche de contact et à la partie supérieure un collet 3 dont le prolongement comporte successivement, de manière connue, des butées de verrouillage 31 destinée à retenir la douille dans le logement d'un support isolant, des languettes de sertissage 32 d'un conducteur à raccorder et des languettes de sertissage 33 de la gaine isolante du conducteur.FIG. 2 represents a developed view of the sleeve, constituted by the blank cut from which it is obtained. In the figures, the ferrule of the sleeve is designated by 1, the edges 11 and 12 of which give rise to the longitudinal joint 10 visible in FIG. 1. The ferrule comprises at the lower part an inlet 2 intended for the insertion of a contact pin and at the upper part a collar 3, the extension of which successively comprises, in known manner, locking stops 31 intended to retain the socket in the housing of an insulating support, crimping tongues 32 of a conductor to connect and crimping tongues 33 of the insulating sheath of the conductor.
La broche de contact, le support isolant du conducteur et le conducteur n'ont pas été représentés car ils ne font pas partie de l'invention. La douille 1 comporte deux languettes de verrouillage 4 et 5 découpées longitudinalement et attenantes à l'entrée 2. Ces languettes 4 et 5 sont encadrées par des fentes longitudinales de découpage telles que 41 et 51, visibles sur la figure 2, ainsi que des fentes transversales de découpage telles que 42 en regard du collet 3. Les languettes 4 et 5 sont séparées entre elles d'un côté interne par une bande de contact 6 interne et du côté externe pour la languette de verrouillage 4 par une bande de contact 7 et pour la languette de verrouillage 5 par une languette de contact 8.The contact pin, the insulating support of the conductor and the conductor have not been shown because they are not part of the invention. The socket 1 has two locking tabs 4 and 5 cut longitudinally and adjoining the inlet 2. These tabs 4 and 5 are framed by longitudinal cutting slots such as 41 and 51, visible in FIG. 2, as well as slots transverse cutting such as 42 opposite the collar 3. The tongues 4 and 5 are separated from each other on an internal side by an internal contact strip 6 and on the external side for the tongue for locking 4 by a contact strip 7 and for the locking tab 5 by a contact tab 8.
Les bandes de contact 6 et 7 relient l'entrée 2 au collet 3, tandis que la languette de contact 8 est attenante au collet 3 mais séparée de l'entrée 2 par une fente de découpage 80 attenante à la fente 51 et la séparant de l'extrémité 23 de l'entrée 2. Les bords extérieurs de la bande 7 et de la languette 8 sont disposés en regard au droit de la jointure longitudinale 10. Mais la bande de contact 8 comporte au droit de cette jointure une découpe longitudinale 70 qui laisse subsister une extrémité 22 sur l'entrée.The contact strips 6 and 7 connect the inlet 2 to the collar 3, while the contact tab 8 is attached to the collar 3 but separated from the inlet 2 by a cutting slot 80 adjoining the slot 51 and separating it from the end 23 of the inlet 2. The outer edges of the strip 7 and of the tongue 8 are arranged facing the right of the longitudinal joint 10. But the contact strip 8 has, at the right of this joint, a longitudinal cut 70 which leaves an end 22 on the entry.
Toutes les languettes et bandes comportent tout autour de la virole et du côté de l'entrée 2 une partie rétreinte telle que 20, visible dans la figure 1. L'extrémité des languettes de verrouillage 4 et 5 est écartée du collet 3 pour pouvoir assurer le verrouillage de rétention dans le logement du support isolant à l'intérieur duquel elles sont destinées à être introduites. L'entrée 2 comporte un chanfrein 21. une telle douille peut être obtenue aisément d'abord par découpes d'un flan tel que celui représenté dans la figure 2, puis par cambrage des languettes et enfin roulage pour former la virole. Le chanfrein 21 peut être réalisé directement par frappe avant roulage.All the tabs and bands have all around the ferrule and on the side of the inlet 2 a constricted part such as 20, visible in FIG. 1. The end of the locking tabs 4 and 5 is spaced from the collar 3 in order to be able the retention lock in the housing of the insulating support inside which they are intended to be introduced. Entrance 2 comprises a chamfer 21. such a socket can be easily obtained first by cutting out a blank such as that shown in FIG. 2, then by bending the tongues and finally rolling to form the ferrule. The chamfer 21 can be produced directly by striking before rolling.
Mais les découpes des languettes et bandes dans le flan sont effectuées de telle sorte pour qu'après roulage d'une part la bande de contact interne 6 soit sensiblement disposée à l'opposé du plan diamétral passant par la jointure longitudinale 10 et que les languettes de verrouillage élastiques 4 et 5 soient disposées sensiblement en opposition selon un plan diamétral.But the cutouts of the tongues and strips in the blank are made so that after rolling on the one hand the internal contact strip 6 is substantially arranged opposite the diametrical plane passing through the longitudinal joint 10 and that the tongues elastic locking devices 4 and 5 are arranged substantially in opposition along a diametrical plane.
Avec une telle configuration dans laquelle la languette de contact 8 est rendue élastique et où les extrémités 22 et 23 de l'entrée 2 sont disposées au contact au niveau de la jointure 10, on obtient un équilibrage des efforts longitudinaux sur la douille et une bonne tenue des languettes de verrouillage qui n'ont plus tendance à s'écarter. Les languettes de verrouillage et les languettes et bandes de contact étant d'autre par disposées au même niveau assurent ainsi un minimum d'encombrement.With such a configuration in which the contact tongue 8 is made elastic and where the ends 22 and 23 of the inlet 2 are arranged in contact at the joint 10, a balance of the longitudinal forces on the sleeve is obtained and good holding locking tabs which no longer tend to move apart. The locking tabs and the tabs and contact strips being otherwise arranged at the same level thus ensure a minimum of space.
Il est évident que l'invention n'est nullement limitée au mode de réalisation qui vient d'être décrit et représenté et qui n'a été donné qu'à titre d'exemple ; en particulier, on peut, sans sortir du cadre de l'invention, modifier certaines dispositions ou remplacer certains moyens par des moyens équivalents, ou encore remplacer certains éléments par d'autres susceptibles d'assurer la même fonction technique ou une fonction technique équivalente. It is obvious that the invention is in no way limited to the mode of realization which has just been described and represented and which has been given only by way of example; in particular, it is possible, without departing from the scope of the invention, to modify certain provisions or replace certain means by equivalent means, or alternatively replace certain elements by others capable of ensuring the same technical function or an equivalent technical function.
