Abstract

Détecteur de proximité notamment pour commande d'allumage de moteur à combustion interne pour véhicule automobile qui comporte un élément isolant 6 assurant le centrage du circuit magnétique 2, 3 dans le boîtier et d'autre part le positionnement de la plaquette 1 dans ledit boîtier, élément qui se présente sous la forme d'un embout partiellement cylindrique, de même diamètre que le diamètre extérieur du circuit magnétique et celui intérieur du boîtier, et qui comporte à une extrémité, un téton cylindrique 6a de diamètre apte à pénétrer dans le centre ouvert du circuit magnétique de façon à le centrer dans le boîtier, à l'autre extrémité une rainure 6d apte à recevoir une extrémité de la plaquette 1 de façon excentrée par rapport à l'axe du circuit magnétique, diamétralement opposées et sur ses flans deux rainures 6c en forme de gouttières aptes à recevoir et à guider les fils 3a de la bobine jusqu'à la plaquette sur laquelle ils sont fixés et symétriquement à la rainure recevant plaquette, un méplat 6b tangent au téton cylindrique.
