Abstract

L'objectif de l'invention est de permettre d'estimer si un couvercle de câbles a été monté dans l'orientation d'ajustement correcte. Un couvercle de câbles (13) est disposé sur une face arrière d'un logement (8) de connecteur femelle, ajusté dans deux orientations d'ajustement, une première et une deuxième, avec des directions d'étirement de câble (W) différentes gauche et droite par rapport au logement (8) de connecteur femelle. Des pistes de détection (26A, 26B) sont formées dans le logement (8) de connecteur femelle, où sont insérées des sondes de détection (29A, 29B). Une dépression de détection (25) est formée au niveau d'une partie d'extrémité d'ouverture d'une des parois latérales du couvercle de câbles (13), et quand le couvercle de câbles (13) est monté dans la seconde orientation d'ajustement, la pointe de la sonde de détection entre dans la dépression de détection (25) sans interférence, tandis que quand il est monté dans la première orientation d'ajustement, la pointe de la sonde de détection (29A, 29B) entre en butée et interfère avec la partie d'extrémité d'ouverture du couvercle de câbles (13). Cela permet une évaluation de l'orientation d'ajustement dans laquelle le couvercle de câbles (13) est monté.
