Abstract

L'invention concerne un trou traversant de branchement (32) d'une fiche (30) à l'intérieur d'un boîtier, ledit trou étant exposé à l'extérieur par l'intermédiaire d'un trou traversant (21) ménagé dans une partie formant paroi (20). Une partie formant châssis est disposée sur la surface intérieure de la partie formant paroi (20) de manière à entourer la fiche (30) et un joint torique (34) vient buter contre la surface intérieure de la partie formant châssis. A ce stade, l'axe central (CL) du joint torique (34) coupe la direction de pénétration du trou traversant (21), cela permettant de réduire l'augmentation d'épaisseur du boîtier (11) due à la présence du joint torique (34), de sorte que l'épaisseur du boîtier peut être réduite tout en assurant une étanchéité à l'eau de cette partie de la fiche (30).
