Abstract

L'invention concerne un connecteur étanche à l'eau qui, lorsqu'un écart de position de rotation se produit par rapport à un élément d'étanchéité, permet une reconnaissance visuelle facile de l'écart de position. Un connecteur étanche à l'eau 10 est pourvu d'un corps 20 de connecteur comportant un boîtier 22, et d'un élément d'étanchéité 30 assurant l'étanchéité d'une partie de coopération avec un connecteur complémentaire. Le boîtier 22 comporte une surface de paroi latérale 223 qui entoure sa périphérie. L'élément d'étanchéité 30 entoure la périphérie de la surface de paroi latérale 223. Une nervure 225 est formée à cet endroit dans le boîtier 22. Ladite nervure 225 forme une paroi verticale le long de la surface d'extrémité avant de l'élément d'étanchéité 30 par rapport à la direction de coopération, et s'étend en ligne droite vers les surfaces supérieure et inférieure du boîtier 22. De plus, des nervures 31 sont formées dans l'élément d'étanchéité 30. Dans les zones gauche et droite de la surface de paroi latérale 223, les nervures 31 font saillie dans la direction de coopération pour atteindre une position chevauchant la nervure 225 par rapport à la direction de coopération, s'étendant ainsi de manière périphérique.
