Abstract

L'invention concerne la connexion de deux conducteurs électriques formés de métaux différents ou d'alliages métalliques différents et, en conséquence, a pour objet un connecteur, dont le corps de connexion est une tôle plaquée comportant deux couches externes, dont le matériau est choisi de manière à correspondre au matériau des conducteurs électriques à connecter, de façon à garantir une connexion de matériaux identiques entre le conducteur électrique et le corps de connexion, et d'éviter ainsi la problématique d'une corrosion électrochimique.
