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
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.ELECTRIC CONNECTOR ELEMENT PROVIDED WITH AN IMPROVED HOUSING
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 able to be assembled with a second case in which is mounted a series of electrical contacts designed for mate with the contacts contained in the first shoemaker and a coupling member which is used to assemble the two shoemakers together.

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. 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. La seconde solution utilise un organe supplémentaire qui se visse derrière l'organe d'accouplement pour maintenir ce dernier en 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. 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. Most electrical connectors use one of two basic solutions to retain a coupling member or ring on one of the shoemakers. The first solution uses a stop ring mounted behind the coupling member to trap an internal shoulder of the coupling member between it and a shoulder of the shoemaker. The second solution uses an additional member which screws behind the coupling member to hold the latter in place. Both solutions work very well, but they both require a certain amount of assembly time and lead to the use of a third member. An example of one of these solutions which requires the use of a third member can be found in US Patent No. 4,109,990 issued 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 to have to use an additional piece in a connector to mount the coupling member on a connector element housing by providing a coupling member retaining mechanism which is part integral with the case 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. 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.  The subject of the invention is therefore an electrical connector element which is characterized in that two annular shoulders are formed on the connector element housing, these two shoulders extending outwards from the housing to trap them the flange formed on the coupling ring. One of the shoulders has a rounded part on which the coupling member is forced back as a result of which 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 lies in that it provides a new solution for mounting a coupling member on the housing 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 lies in that the retaining mechanism eliminates the need to have to use an additional member to mount the coupling member on the boot.

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 required to assemble the coupling member on the housing of the connector element.

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:
la Fig. 1 est une vue schématique d'un élément de connecteur électrique mettant en oeuvre les principes de 1 'inven- tion;
la Fig. 2 est une vue en coupe du connecteur électrique représentd sur la Fig. 1; et
la Fig. 3 représente un autre mode de réalisation de l'invention.Other characteristics of the invention will appear on reading the description which follows and on examining the appended drawing in which:
Fig. 1 is a schematic view of an electrical connector element implementing the principles of the invention;
Fig. 2 is a sectional view of the electrical connector shown in FIG. 1; and
Fig. 3 shows another embodiment of the invention.

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 be made, FIG. 1 represents an electrical connector element which comprises, in a general manner, a plastic casing 20 molded in one piece in which several contacts 40 are mounted and a ring d coupling 10 mounted on the housing 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 generally comprises a thread formed in its front part designed to be screwed onto a corresponding thread formed on a similar connector housing, and an annular flange 11 extending inward which has a surface 12 oriented towards the rear.

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 comprises first and second annular shoulders 21, 22. The shoulders 21, 22 trap between them the shoulder 11 of the ring or coupling member and serve to mount the coupling member 10 to rotate on the shoemaker 20. The second shoulder 22 has a curved surface and a flat surface so that the end of the flange 11 can be pushed back over the rounded part of the shoulder and mounted in place by snap engagement between the shoulders 21, 22. A corrugated washer 30 produces a biasing force directed towards the rear between the shoulder 22 of the shoemaker and the shoulder 11 of the coupling member.

La Fig. 2 est une vue en coupe du connecteur représenté sur la Fig. 1 et elle montre la configuration du second épaulement 22 qui fait partie intégrante du bottier 20 de l'élément de connecteur. 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. Le second épaulement 22 peut être constitué par un unique épaulement continu ou il peut être composé d'un ou de plusieurs segments annulaires 22 disposés, comme représenté, autour du bottier 20. Fig. 2 is a sectional view of the connector shown in FIG. 1 and it shows the configuration of the second shoulder 22 which is an integral part of the boot 20 of the connector element. In the preferred embodiment, the housing of the connector element and / or the coupling ring are molded from a plastic material, such as "Torlon" or any other similar material which is rigid and resistant. The second shoulder 22 may consist of a single continuous shoulder or it may be composed of one or more annular segments 22 arranged, as shown, around the shoemaker 20.

La Fig. 3 représente un autre mode de réalisation de l'invention dans lequel le second épaulement venu de matière 22 est disposé de l'autre c8té du premier épaulement 21 pour emprisonner le rebord i1 de l'organe d'accouplement entre le premier épaulement 21 et le second épaulement 22 du bottier 20. Fig. 3 shows another embodiment of the invention in which the second shoulder made of material 22 is disposed on the other side of the first shoulder 21 to trap the rim i1 of the coupling member between the first shoulder 21 and the second shoulder 22 of bootmaker 20.

Bien qu'on ait décrit et représenté un mode de réalisation préféré de l'invention, il apparaitra aux spécialistes de la technique que l'on peut apporter de nombreux changements à l'invention telle que revendiquée dans les revendiá- tions annexées et que, dans certains cas, certaines caractéristiques de l'invention peuvent être utilisées avantageusement sans l'emploi d'autres caractéristiques. Par exemple, bien que, dans le mode de réalisation préféré représenté, le bottier de l'élément de connecteur soit cylindrique, llinven- tion s'applique également à un bottier d'élément de connecteur rectangulaire. En outre, le second épaulement peut ne pas être venu de moulage avec le boîtier 20 et peut éventuel lement être un élément séparé. Par conséquent, il est bien entendu que tous les éléments de la description qui précède n'ont été donnés que dans le but d'illustrer les principes de l'invention et non pour en limiter la portée.  Although a preferred embodiment has been described and shown, it will be apparent to those skilled in the art that there can be many changes to the invention as claimed in the appended claims and that, in certain cases, certain characteristics of the invention can be used advantageously without the use of other characteristics. For example, although in the preferred embodiment shown, the housing of the connector element is cylindrical, the invention also applies to a housing of the rectangular connector element. In addition, the second shoulder may not have come from molding with the housing 20 and may possibly be a separate element. Consequently, it is understood that all the elements of the foregoing description have been given only for the purpose of illustrating the principles of the invention and not to limit its scope.
