Abstract

L'objectif de la présente invention est de fournir une sortie USB dans laquelle la quantité de projection à partir d'un conduit de câblage est petite dans un état fixé au conduit de câblage. Un boîtier (10) d'une sortie USB (1) loge un substrat (40) et un élément de support (50). Une partie de raccordement de conduit (60) à connecter à un conduit de câblage est disposée dans une paroi arrière (102) du boîtier (10). L'élément de support (50) supporte une pluralité de contacteurs (62) entre l'élément de support et la paroi arrière (102) du boîtier (10) à l'intérieur du boîtier (10). Sur le substrat (40), une pluralité de composants de circuit (21) et de prises USB (22) sont montés sur une seconde surface (402) opposée à une première surface (401) qui fait face à l'élément de support (50).
