Abstract

Selon l'invention, il est possible de simplifier considérablement la configuration d'un connecteur électrique par omission d'une carte de circuit imprimé, d'un connecteur électrique s'associant dans un emboîtement, ou similaire. Un connecteur mâle autonome (10) s'emboîte directement avec une partie paroi d'un boîtier de produit (MF), et une partie contact d'un contact (12) est mise en contact avec une partie contact d'un trajet de conduction électrique de schéma de câblage (CP) exposé à la surface d'un orifice de raccordement pour emboîtement (MFa), dans un état où le connecteur mâle autonome (10) est emboîté. Par conséquent, une connexion électrique d'un support de transmission de signaux est effectuée par une configuration simple, sans l'intermédiaire comme dans l'art antérieur d'une carte de circuit imprimé ou d'un connecteur électrique s'associant dans un emboîtement. En outre, la fixation finale du connecteur électrique, est effectuée par maintien de chaque côté et dans la direction de l'épaisseur, du boîtier de produit entre un contact de conducteur et une partie patte de raccordement d'une partie corps principal de connecteur, et ses propriétés de raccordement pour emboîtement sont préservées de manière satisfaisante y compris dans le cas d'emboîtements/retraits répétés du connecteur électrique.
