Abstract

The device attaches the elastomer bellows to the cylindrical cable bundle termination (10) by pushing the end of the bellows over the cylindrical termination. An internal flange (17) fitted in the end of the bellows engages in a peripheral groove (18) formed on the cylindrical termination. An elastic ring (19) made of metal or hard plastic is moulded inside the bellows adjacent to the internal flange. The elastic ring is split, and two radial tongues are brought out to the side, forming a circlip. The radial tongues allow attachment of a tool to either tighten the ring or loosen it to allow removal of the bellows for maintenance.

Description

L'invention est relative à un dispositif de raccordement d'un soufflet d'étanchéité sur un corps cylindrique. The invention relates to a device for connecting a sealing bellows to a cylindrical body.

Elle se rapporte plus particulièrement aux soufflets constituant une gaine souple de protection qui enveloppe un faisceau de fils électriques parvenant au corps cylindrique, en le traversant ou en y aboutissant s'il s'agit d'un connecteur. Un tel raccordement s'effectue notamment dans des véhicules automobiles, au droit de la jonction entre un panneau ouvrant et un élément fixe de la carrosserie. It relates more particularly to the bellows constituting a flexible protective sheath which envelops a bundle of electric wires reaching the cylindrical body, passing through it or terminating there if it is a connector. Such a connection is made in particular in motor vehicles, at the junction between an opening panel and a fixed element of the bodywork.

La liaison entre le soufflet et le corps cylindrique s'effectue habituellement par emmanchement sur ce dernier d'un manchon d'extrémité du soufflet, dont le maintien est assuré soit par adjonction d'un collier de serrage, soit plus simplement par engagement d'un bourrelet interne du manchon dans une gorge périphérique du corps cylindrique. The connection between the bellows and the cylindrical body is usually effected by fitting on the latter of an end sleeve of the bellows, the maintenance of which is ensured either by adding a clamp, or more simply by engagement of an internal bead of the sleeve in a peripheral groove of the cylindrical body.

Ce dernier agencement est peu coûteux et permet un assemblage rapide. Toutefois, pour que le maintien soit suffisamment ferme et que l'étanchéité soit correctement assurée entre le corps cylindrique et le soufflet, le serrage du bourrelet dans la gorge doit être fort, et par suite le montage et le démontage éventuel du soufflet s'avèrent très difficiles et risquent d'entraîner une détérioration. This latter arrangement is inexpensive and allows rapid assembly. However, for the support to be sufficiently firm and for the seal to be correctly ensured between the cylindrical body and the bellows, the tightening of the bead in the groove must be strong, and consequently the mounting and possible dismantling of the bellows prove very difficult and may cause deterioration.

L'invention vise à remédier à cet inconvénient en proposant un agencement de ce dernier type, dans lequel le soufflet puisse être emmanché aisément sur le corps cylindrique. Elle concerne un dispositif de raccordement d'un soufflet en matière élastomère sur un corps cylindrique, dans lequel un manchon d'extrémité du soufflet est emmanché sur ce corps et comporte un bourrelet intérieur engagé dans une gorge périphérique du corps. Selon l'invention, un anneau fendu élastique en métal ou en matière plastique dure est intégré par surmoulage dans le manchon au droit du bourrelet et comporte à chacune de ses deux extrémités une extension radiale qui émerge du manchon. The invention aims to remedy this drawback by proposing an arrangement of the latter type, in which the bellows can be easily fitted onto the cylindrical body. It relates to a device for connecting a bellows made of elastomeric material to a cylindrical body, in which an end sleeve of the bellows is fitted on this body and comprises an internal bead engaged in a peripheral groove of the body. According to the invention, an elastic split ring made of metal or of hard plastic material is integrated by overmolding in the sleeve in line with the bead and comprises at each of its two ends a radial extension which emerges from the sleeve.

Selon une disposition avantageuse, les deux extensions radiales comportent chacune un évidement propre à recevoir l'un de deux ergots d'un outil d'écartement de l'anneau.  According to an advantageous arrangement, the two radial extensions each have a recess adapted to receive one of two lugs of a tool for spacing the ring.

Un mode de réalisation d'un raccordement selon l'invention est décrit ci-après, avec référence aux dessins annexés parmi lesquels:
- ia figure 1 est une vue en coupe axiale partielle des pièces raccordées,
- et la figure 2 est une vue en coupe transversale suivant la ligne ll-ll de la figure 1.
An embodiment of a connection according to the invention is described below, with reference to the appended drawings in which:
FIG. 1 is a view in partial axial section of the connected parts,
- And Figure 2 is a cross-sectional view along line II-II of Figure 1.

On voit sur les figures un soufflet 1 qui enveloppe un tronçon 2 d'un faisceau de fils électriques 3 et qui relie une paroi 4 à une interconnexion 5 fixée à une autre paroi 6. Ces deux parois sont par exemple des éléments de carrosserie d'un véhicule automobile, respectivement solidaires d'un panneau ouvrant et d'une partie fixe du véhicule. We see in the figures a bellows 1 which envelops a section 2 of a bundle of electrical wires 3 and which connects a wall 4 to an interconnection 5 fixed to another wall 6. These two walls are for example bodywork elements of a motor vehicle, respectively secured to an opening panel and to a fixed part of the vehicle.

Le soufflet est constitué d'un fourreau ondulé en matière élastomère dont une extrémité 7 est accrochée de façon étanche au bord d'une ouverture 8 par laquelle le faisceau 2 traverse la paroi 4, et dont l'extrémité opposée 9 constitue un manchon engagé sur une partie externe cylindrique 10 de l'interconnexion 5. The bellows consists of a corrugated sheath made of elastomeric material, one end of which 7 is tightly hung at the edge of an opening 8 through which the bundle 2 passes through the wall 4, and the opposite end of which constitutes a sleeve engaged on a cylindrical external part 10 of the interconnection 5.

Cette interconnexion (dont la partie interne, usuelle, n'est pas représentée sur la figure mais cachée par des hachures) comporte deux connecteurs 11 et 12, respectivement mâle et femelle, auxquels aboutissent d'un côté les fils 3 du tronçon de faisceau 2, et de l'autre côté des fils d'un autre tronçon de faisceau 13. Ils sont reliés entre eux par un écrou 14, et deux joints toriques 15 et 16 assurent l'étanchéité au droit de leur face d'appui et de celle de la paroi 6. This interconnection (the usual internal part of which is not shown in the figure but hidden by hatching) comprises two connectors 11 and 12, respectively male and female, to which the wires 3 of the bundle section 2 end on one side. , and on the other side of the wires of another bundle section 13. They are interconnected by a nut 14, and two O-rings 15 and 16 ensure the sealing at right of their bearing face and that of the wall 6.

Pour assurer un maintien ferme du soufflet 1 sur le connecteur 11, le manchon comporte un bourrelet 17 engagé dans une gorge périphérique 18 de ce connecteur, et selon l'invention, un anneau fendu élastique 19 en métal ou en matière plastique dure- est inséré par surmoulage dans le manchon au droit du bourrelet. To ensure a firm hold of the bellows 1 on the connector 11, the sleeve comprises a bead 17 engaged in a peripheral groove 18 of this connector, and according to the invention, an elastic split ring 19 made of metal or of hard plastic material is inserted by overmolding in the sleeve to the right of the bead.

Les deux extrémités de l'anneau, espacées par une fente E, comportent chacune une extension radiale (20) qui émerge du manchon et dans laquelle est pratiqué un évidement (21) propre à recevoir l'un de deux ergots d'un outil connu formant pince d'écartement de l'anneau, lors du montage ou d'un éventuel démontage du soufflet. The two ends of the ring, spaced by a slot E, each have a radial extension (20) which emerges from the sleeve and in which is formed a recess (21) suitable for receiving one of two lugs of a known tool forming a ring spacer, during assembly or possible disassembly of the bellows.

Ce liaison du manchon 9 avec la partie cylindre 10 du connecteur 11 garantit en plus du maintien ferme, une bonne étanchéité évitant toute introduction d'eau dans le soufflet 1, ce qui permet d'éviter l'habituel agencement difficile et coûteux d'un moyen d'étanchéité au droit du raccordement des fils électriques 3 avec le connecteur 11. This connection of the sleeve 9 with the cylinder part 10 of the connector 11 guarantees, in addition to the firm hold, a good seal preventing any introduction of water into the bellows 1, which makes it possible to avoid the usual difficult and expensive arrangement of a sealing means to the right of the connection of the electric wires 3 with the connector 11.

En variante, le manchon peut être raccordé à une autre partie cylindrique de l'interconnexion, par exemple sur une large collerette annulaire du connecteur 12 agencée de manière que le soufflet entoure non seulement le tronçon de faisceau 2 mais aussi le connecteur 11 et l'écrou 14.  Alternatively, the sleeve can be connected to another cylindrical part of the interconnection, for example on a large annular flange of the connector 12 arranged so that the bellows surrounds not only the bundle section 2 but also the connector 11 and the nut 14.
