Abstract

The coupling ring is fitted to the connector using force and locks itself into a retaining groove without supplementary parts and offering a lower cost. The connector body (20) and the coupling ring are made of a rigid plastics such as TORLON (RTM), the connector having several contact pins (40). The coupling ring (10) is tubular with an annular internal rim (11) and an internal thread (15) to mate with the other part of the connector. On the connector body are two shoulders (21,22) with plane facing edges, but one shoulder having a sloped outer edge. The coupling ring is held by its rim between the two shoulders but is free to rotate. The rim is pressed against the rear shoulder of the connector by a corrugated washer (30) mounted between the rim and the front shoulder. The connector body is produced as a single piece moulding.

Description

ELEMENT DE CONNECTEUR éLECTRIQUE MUNI D'UN BOITIER PERFECTIONNE ELEMENT ELECTRICAL CONNECTOR WITH A PERFECT CASE
La présente invention se rapporte à un ensemble de connecteur électrique du type qui comporte un premier boîtier dans lequel est montée une série de contacts électriques et qui est agencé pour pouvoir ètre assemblé à un second bottier dans lequel est montée une série de contacts électriques conçus pour s'accoupler aux contacts contenus dans le premier bottier et un organe d'accouplement qui sert à assembler entre eux les deux bottiers. The present invention relates to an electrical connector assembly of the type which comprises a first housing in which is mounted a series of electrical contacts and which is arranged to be assembled with a second stacked in which is mounted a series of electric contacts designed for mate with contacts contained in the first stacked and a coupling member that is used to assemble together the two boot makers.

La plupart des connecteurs électriques utilisent l'une de deux solutions de base pour retenir un organe ou bague d'accouplement sur l'un des bottiers. Most electrical connectors use one of two basic solutions for holding a member or coupling ring on one of the boot makers. La première solution utilise un jonc d'arrêt monté derrière l'organe d'accouplement pour emprisonner un épaulement interne de l'organe d'accouplement entre lui et un épaulement du bottier. The first solution uses a snap ring mounted behind the coupling member to trap an internal shoulder of the coupling member between it and a shoulder of the casing. La seconde solution utilise un organe supplémentaire qui se visse derrière l'organe d'accouplement pour maintenir ce dernier en place. The second solution uses an additional member which is screwed behind the coupling member to hold the latter in place. Les deux solutions fonctionnent très bien, mais elles exigent toutes deux un certain temps d'assemblage et en tratnent l'emploi d'un troisième organe. Both solutions work very well, but they both require some assembly time and tratnent the use of a third body. Un exemple d'une de ces solutions qui nécessitent l'emploi d'un troisième organe peut être trouvé dans le brevet des EUA nO 4.109.990 délivré le 29 août 1978. An example of one of these solutions require the use of a third body can be found in US Patent 4,109,990 issued nO August 29, 1978.

L'invention supprime la nécessité d'avoir à utiliser dans un connecteur une pièce supplémentaire pour monter l'or- gane d'accouplement sur un bottier d'élément de connecteur en réalisant un mécanisme de retenue d'organe d'accouplement qui fait partie intégrante du bottier de l'élément de connecteur électrique. The invention eliminates the need for a connector for use in an extra room for mounting the coupling member on a connector element stacked by providing a coupling member retaining mechanism part integral of the casing of the electrical connector element.

L'invention a ainsi pour objet un élément de connecteur électrique qui est caractérisé en ce que deux épaulements annulaires sont formés sur le bottier d'élément de connecteur, ces deux épaulements s'étendant vers l'extérieur à partir du boîtier pour emprisonner entre eux le rebord formé sur la bague d'accouplement. The invention thus relates to an electrical connector element which is characterized in that two annular shoulders are formed on the connector element stacked, these two shoulders extending outwardly from the housing to trap them the flange formed on the coupling ring. Un des épaulements comporte une partie arrondie sur laquelle l'organe d'accouplement est repoussé à force à la suite de quoi il s'engage brusquement en place entre les surfaces plates des deux épaulements. One of the shoulders has a rounded portion on which the coupling member is pushed in to force whereupon it suddenly engages in place between the flat surfaces of the two shoulders.

Un avantage de l'invention réside en ce qu'elle fournit une nouvelle solution pour le montage d'un organe d'accouplement sur le boiter d'un élément de connecteur. An advantage of the invention is that it provides a new solution for mounting a coupling member on the limping of a connector element.

Un autre avantage de l'invention réside en ce que le mécanisme de retenue supprime la nécessité d'avoir à employer un organe supplémentaire pour monter l'organe d'accouplement sur le bottier. Another advantage of the invention is that the retaining mechanism eliminates the need to use an additional body to mount the coupling member on the bootmaker.

Encore un autre avantage de l'invention est qu'elle réduit le temps nécessaire pour assembler l'organe d'accouplement sur le bottier de l'élément de connecteur. Yet another advantage of the invention is that it reduces the time needed to assemble the coupling member on the stacked member of the connector.

Un avantage supplémentaire de l'invention est qu'elle réduit le coût de l'ensemble de connecteur. An additional advantage of the invention is that it reduces the cost of the connector assembly.

D'autres caractéristiques de l'invention apparaitront à la lecture de la description qui va suivre et à l'examen du dessin annexé dans lequel: Other features of the invention will appear from reading the following description and examining the accompanying drawings in which:

Sur le dessin auquel on se référera maintenant, la Fig.1 représente un élément de connecteur électrique qui comporte, d'une marnière générale, un bottier 20 en matière plastique moulé en une seule pièce dans lequel plusieurs contacts 40 sont montés et une bague d'accouplement 10 montée sur le bottier 20 de l'élément de connecteur. In the drawing to which reference will now Fig.1 shows an electrical connector element which comprises, in general marl pit, a housing 20 of plastics material molded in one piece wherein a plurality of contacts 40 are mounted and a ring coupling 10 mounted on the stacked 20 of the connector element.

La bague d'accouplement 10 comporte, d'une manière générale, un filetage formé dans sa partie avant conçu pour se visser sur un filetage correspondant formé sur un boîtier d'é- dément de connecteur similaire, et un rebord annulaire 11 s'étendant vers l'intérieur qui comporte une surface 12 orientée vers l'arrière. The coupling ring 10 comprises, generally, a thread formed in its front portion adapted to be screwed onto a corresponding thread formed on an housing E- demented similar connector, and an annular flange 11 extending inwardly having a surface 12 facing rearwardly.

Le boîtier 20 de l'élément de connecteur comporte des premier et second épaulements annulaires 21, 22. Les épaulements 21, 22 emprisonnent entre eux l'épaulement 11 de la bague ou organe d'accouplement et servent à monter l'organe d'accouplement 10 à rotation sur le bottier 20. Le second épaulement 22 a une surface incurvée et une surface plate de sorte que l'extrémité du rebord 11 peut être repoussée par dessus la partie arrondie de l'épaulement et montée en place par enclenchement brusque entre les épaulements 21, 22. Une rondelle ondulée 30 produit une force de sollicitation dirigée vers l'arrière entre l'épaulement 22 du bottier et l'épaulement 11 de l'organe d'accouplement. The housing 20 of the connector element includes first and second annular shoulders 21, 22. The shoulders 21, 22 trap therebetween the shoulder 11 of the ring or coupling element and serve to mount the coupling member 10 to rotate on the stacked 20. the second shoulder 22 has a curved surface and a flat surface so that the end of the flange 11 can be pushed over the rounded portion of the shoulder and mounted in place by snap engagement between the shoulders 21, 22. a wave washer 30 produces a biasing force directed towards the rear between the shoulder 22 of the casing and the shoulder 11 of the coupling member.

La Fig. Fig. 2 est une vue en coupe du connecteur représenté sur la Fig. 2 is a sectional view of the connector shown in Fig. 1 et elle montre la configuration du second épaulement 22 qui fait partie intégrante du bottier 20 de l'élément de connecteur. 1 and shows the configuration of the second shoulder 22 which forms an integral part of the casing 20 of the connector element. Dans le mode de réalisation préféré, le boîtier de l'élément de connecteur et/ou la bague d'accouplement sont moulés en une matière plastique, telle que du "Torlon" ou toute autre matière similaire qui est rigide et résistante.
