  • the connector according to the embodiment of the present invention is effective when the counterpart housing portion is not clearly seen by visual observation, but can be used even when the counterpart housing portion is visible. That is, the fitting operation can be easily performed without considering the direction (rotational position) of the counterpart housing portion.

Abstract

Selon la présente invention, une section presseuse (14) presse un premier logement (2), lequel a une première borne, par rapport à un troisième logement (10) vers une position préajustée. Un rail de guidage/rotation (20) est configuré de telle manière que la force de pression, laquelle est transmise du premier logement (2) situé à une position de pression, entraîne le suivi de la rotation circonférentielle du premier logement (2) par un corps tubulaire (5) et sa rotation par rapport au troisième logement (10). Quand la direction d'ajustement du premier logement (2) dans un deuxième logement (31), lequel a une deuxième borne, est différente, le premier logement (2) tourne par rapport au troisième logement (10) et est ajusté au deuxième logement (31). La première borne et la deuxième borne sont connectées entre elles dans un état dans lequel les premier et deuxième logements (2, 31) sont ajustés l'un à l'autre.
