Abstract

La présente invention concerne un connecteur de module permettant d'obtenir une réduction des dimensions, une meilleure adaptation, et une diminution des coûts en améliorant le procédé de connexion entre une borne installée dans un boîtier supérieur de module et un substrat de module monté dans un boîtier inférieur de module. Le connecteur de module comprend : une pluralité de bornes de contact (1012) côté boîtier ; et une pluralité de plots de connexion (1023) disposés sur le substrat (1022) du module fixé dans un boîtier (1021) côté module. Chacune des bornes de contact (1012) côté boîtier comprend : une partie de contact (1012a) de connecteur amenée en contact, au moment du couplage du connecteur, avec chaque borne d'une pluralité de bornes de contact (112) côté câble connectées à un câble multiconducteur (10) ; une partie ressort (1012b) possédant des propriétés de ressort ; et une partie (1012c) de connexion de substrat fixée sur le substrat (1022) du module. Chaque borne parmi lesdites bornes de contact (1012) côté boîtier prend la forme d'un corps unique de telle sorte que la partie ressort (1012b) est disposée entre la partie de contact (1012a) de connecteur et la partie (1012c) de connexion de substrat.
