Abstract

Selon la présente invention, la section de paroi gauche (50) du boîtier (12) de ce connecteur (10) a une section de retenue gauche (50) formée sur cette dernière, et la surface de mise en prise gauche (64) de la section de mise en prise gauche (62) d'une partie avant (40) est en contact avec la surface de contact gauche (52) de la section de retenue gauche (50). De plus, la section de paroi droite (50) du boîtier (12) a une section de retenue droite (54) formée sur cette dernière, et la surface de mise en prise droite (68) de la section de mise en prise droite (66) de la partie avant (40) est en contact avec la surface de contact droite (56) de la section de retenue droite (54). En raison de cette configuration, le déplacement vers l'avant de la partie avant (40) par rapport au boîtier (12) peut être limité.
