Abstract

Selon l'invention, un composant d'emboutissage de carte (20) comprend une saillie guide de câble d'alimentation électrique (26) pénétrant au travers d'une carte de capteur (13), et une face côté stator (13-1) de la carte de capteur (13) est câblée à un câble d'alimentation électrique (22) guidé par la saillie guide de câble d'alimentation électrique (26) et câblé de façon à contourner un circuit de capteur (25) afin de ne pas toucher le circuit de capteur (25). La carte de capteur (13) comprend une fente (41) formée pour être plus large dans une largeur radiale qu'une zone du câble d'alimentation électrique (22) dépassant vers la carte de capteur (13) et aussi formée avec une taille suffisante pour pouvoir insérer au travers les saillies guides de câble d'alimentation électrique (26).
