Abstract

L'invention concerne un connecteur (10) qui comprend un logement de connecteur (20) lequel héberge une borne femelle, et une retenue (40) qui comprend une pièce de verrouillage élastiquement déformable (46) et qui est introduite dans un orifice de montage de retenue (23) du logement de connecteur (20). Selon la présente invention, la retenue (40) peut se déplacer entre une position d'emboîtement temporaire éloignée d'un passage d'accès pour la borne femelle et une position d'emboîtement principale dans le passage d'accès de la borne femelle. La pièce de verrouillage (46) comprend une mâchoire d'emboîtement principale (48) qui maintient la retenue (40) au niveau de la position d'emboîtement principale par un emboîtement vers le bas d'une protubérance d'emboîtement principale (27), et une mâchoire d'emboîtement temporaire (47) qui maintient la retenue (40) au niveau de la position d'emboîtement temporaire par un emboîtement vers le bas d'une protubérance d'emboîtement temporaire (28). L'ampleur du déplacement de la mâchoire d'emboîtement temporaire (47) produite par déformation élastique de la pièce de verrouillage (46) est inférieure à l'ampleur du déplacement de la mâchoire d'emboîtement principale (48).
