Abstract

La présente invention concerne un connecteur mâle électrique qui comprend un premier corps isolant (21), une pluralité de bornes conductrices (23) encastrées dans le premier corps isolant et un câble (25) qui comprend de multiples lignes branches. La borne conductrice comprend une partie d'accouplement (236) qui fait saillie sur la surface du premier corps isolant et une partie de soudage de fil (237) exposée sur l'extérieur du premier corps isolant. Chaque ligne branche du câble est soudée à la partie de soudage de fil, respectivement. Le connecteur mâle électrique comprend un second corps isolant (22) qui comprend au moins un trou en forme de bande (43, 44) et une rainure de réception (225). La partie d'accouplement de la borne conductrice est exposée dans le trou en forme de bande afin d'être électriquement connectée à un connecteur femelle électrique. La partie de soudage de fil de la borne conductrice est reçue dans la rainure de réception. Le connecteur mâle électrique est empêché d'être soudé dans les rainures de réception. Ainsi, le problème des bornes conductrices soudées les unes aux autres en raison de l'espace étroit dans la rainure de réception est évité. La présente invention permet une fiabilité plus élevée du soudage entre le câble et les bornes conductrices.
