Abstract

Un aspect de la présente invention concerne un connecteur de charge qui peut être de taille réduite. Le connecteur de charge (10) comprend : un boîtier (11) ; une paire de bornes d'alimentation ; une première borne de relais (21) et une seconde borne de relais (22) qui sont respectivement fixées à la paire de bornes d'alimentation par fixation de boulon ; une paire de lignes d'alimentation (24) qui sont respectivement connectées à la première borne de relais (21) et à la seconde borne de relais (22) ; et une pluralité de bornes de signal (15) qui sont logées dans le boîtier (11). Vue depuis une direction d'insertion/retrait (Y) le long d'une direction d'ajustement, la pluralité de bornes de signal (15) sont disposées uniquement dans une seconde région (A2) parmi une première région (A1) et la seconde région (A2) qui sont séparées par une ligne droite de référence (L2). Une partie de connexion de fil électrique (82) de la première borne de relais (21) est située dans la première région (A1) lorsqu'elle est vue depuis la direction d'insertion/retrait (Y).
