Abstract

L'invention porte sur un connecteur mobile dont la facilité de la liaison par emboîtement et la stabilité de la connexion conductrice sont améliorées. Un connecteur mobile (1) est en outre muni d'un boîtier d'actionnement (5) permettant de comprimer un boîtier mobile (4) dans une direction d'intersection (direction Y) coupant la direction d'insertion (direction Z) d'une borne à broche (P2) dans une chambre de connexion (4e). Lorsqu'il est comprimé par le boîtier d'actionnement (5), le boîtier mobile (4) est déplacé dans la direction d'intersection par rapport à la borne à broche (P2). Lorsque le boîtier mobile (4) est déplacé relativement, une section de contact (6e) se rapproche davantage vers la borne à broche (P2) et entre en contact par pression avec la borne à broche (P2).
