Description
La présente invention vise un joint monté dans un connecteur étanche.The present invention relates to a seal mounted in a waterproof connector.
L'invention se rapporte à un joint destiné à être utilisé avec des connecteurs comprenant un élément de boítier femelle présentant une jupe destinée à recevoir un élément de boítier mâle et dans laquelle s'étendent des broches destinées à coopérer avec des organes de connexions électriques femelles de l'élément de boítier mâle, ledit joint étant monté dans la jupe et présentant des conduits traversés par les broches.The invention relates to a seal intended for be used with connectors comprising an element female housing having a skirt intended to receive a male housing element and in which extend pins intended to cooperate with connection members female electrical components of the male housing element, said gasket being mounted in the skirt and having conduits crossed by the pins.
L'un des buts de la présente invention est de réaliser un joint du type ci-dessus qui permette aux éléments de boítier d'être accouplés et désaccouplés sans risque de diminuer son efficacité.One of the aims of the present invention is to make a joint of the above type which allows the elements to be safely coupled and uncoupled to decrease its effectiveness.
Le joint, selon l'invention, est monté dans des connecteurs électriques étanches du type comprenant un élément de boítier mâle et un élément de boítier femelle présentant une jupe destinée à recevoir l'élément de boítier mâle, ledit élément de boítier femelle comportant un élément isolant dans lequel sont logés des organes de connexions prolongés par des broches qui font saillie dans la jupe, tandis que l'élément de boítier mâle est pourvu d'un prolongement s'insérant dans la jupe et dans lequel est fixé un corps isolant recevant des organes de connexions électriques femelles destinés à coopérer avec les broches, le joint étant du type en matière souple et élastique comprenant une embase avec des cheminées percées de conduits pour le passage des broches, ledit joint étant engagé dans la jupe pour porter, par son embase, contre l'élément isolant dudit élément de boítier femelle, ledit joint étant caractérisé en ce que chaque conduit, en partant de l'embase, présente une première partie cylindrique ayant un diamètre légèrement inférieur à celui des broches et prolongée par une partie en forme de tronc de cône renversé, elle-même prolongée par une partie en forme de tronc de cône, terminée par une seconde partie cylindrique, tandis que l'embase est bordée par un rebord au voisinage duquel, du côté opposé à l'embase, s'étend une lèvre périphérique, tandis que le corps isolant de l'élément de boítier mâle vient porter contre le bord des conduits opposé à l'embase afin que la seconde partie cylindrique, en coulissant légèrement sur les broches enserre celles-ci, le prolongement par son bord libre portant contre la lèvre afin d'appliquer celle-ci contre la surface interne de la jupe.The seal according to the invention is mounted in waterproof electrical connectors of the type comprising a male housing element and a female housing element having a skirt intended to receive the male housing element, said female housing element comprising an insulating element in which are housed extended connection members by pins that protrude into the skirt, while the male housing element is provided with an insertable extension in the skirt and in which an insulating body is fixed receiving organs of female electrical connections intended to cooperate with the pins, the seal being type of flexible and elastic material comprising a base with chimneys pierced with conduits for passage pins, said seal being engaged in the skirt for bear, by its base, against the insulating element of said element female housing, said seal being characterized in what each conduit, starting from the base, presents a first cylindrical part having a diameter slightly lower than that of the pins and extended by part in the shape of an inverted truncated cone, itself extended by a part in the shape of a truncated cone, terminated by a second cylindrical part, while the base is bordered by a flange in the vicinity of which, on the side opposite to the base, extends a peripheral lip, while the insulating body of the male housing element comes to bear against the edge conduits opposite the base so that the second part cylindrical, sliding slightly on the enclosed pins these, the extension by its free edge bearing against the lip in order to apply it against the internal surface of the skirt.
Grâce à cette disposition, lorsqu'on assemble les deux éléments de boítier, l'élément mâle tend à pousser la lèvre périphérique contre la paroi interne de la jupe, tandis que chaque cheminée est légèrement déformée pour être comprimée vers l'embase. Ainsi, on réalise une étanchéité, d'une part autour des broches et, d'autre part, le long de la jupe.Thanks to this arrangement, when assembling the two housing elements, the male element tends to push the peripheral lip against the inner wall of the skirt, while each chimney is slightly deformed to be compressed towards the base. Thus, we realize a tightness, on the one hand around the pins and, on the other hand, along the skirt.
Un autre avantage de l'invention est que le joint ne constitue pas un frein obligeant à augmenter la force d'insertion de l'élément de boítier mâle dans l'élément de boítier femelle. Another advantage of the invention is that the seal does not constitute a brake requiring an increase in insertion force of the male housing element in the element female housing.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described with more details with reference to an embodiment particular given by way of example only and shown to the accompanying drawings, in which:

L'extrémité de l'élément 10, opposée à la jupe,
est remplie, soit d'une colle, soit d'une résine 16 qui
ferme d'une manière étanche l'élément 10 en incluant les
conducteurs 15.The end of the
Le joint est monté dans la jupe 12 de manière
que sa base 1 coopère avec la face correspondante 13a de
l'élément isolant 13, une mince couche de colle étant appliquée
sur cette face.The seal is mounted in the
Les parties 3a des conduits 3 ont un diamètre
légèrement inférieur au diamètre des broches 14, tandis
que les parties 3d ont un diamètre supérieur à celui
desdites broches.The
L'élément de boítier femelle 10 présente, à
chaque extrémité (voir figure 5), un écrou 18 pour sa fixation
avec un élément de boítier mâle 20.The
L'élément de boítier mâle 20 comprend une enveloppe
métallique 21 présentant un prolongement 22 destiné
à s'insérer dans la jupe 12 et dans lequel est monté
un corps isolant 24 dans lequel sont logés et fixés des
organes femelles de connexions électriques 25 destinés à
recevoir, chacun, une broche 14. Chaque organe 25 est relié
à un conducteur (non représenté).The
L'élément de boítier mâle 20, du côté opposé
au prolongement 22, est fermé par une colle ou une résine
27.The

extrémité, une vis prisonnière 28 (voir figure 5) destinée
à se visser dans l'écrou 18 afin d'assurer l'assemblage
des deux éléments de boítier.The
Comme on le voit à la figure 4 lorsque les deux
éléments de boítier 10 et 20 sont assemblés, le bord du
prolongement 22 porte contre la lèvre 4 et tend ainsi à
appliquer la lèvre 4 contre la surface interne de la jupe
12. As seen in Figure 4 when the two

Les éléments de boítier peuvent être accouplés ou désaccouplés de nombreuses fois sans risque pour le joint.Housing elements can be coupled or uncoupled many times without risk to the joint.
De plus, compte tenu de la conception du joint, l'accouplement des éléments de boítier ne nécessite pas d'efforts d'insertion importants.In addition, given the design of the seal, the coupling of the housing elements does not require significant integration efforts.
Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. We can make many modifications detail without departing from the scope of the invention.
