Abstract

La présente invention concerne des connexions électriques entre de l'aluminium et un contact de métal différent tel que du cuivre, destinées à être utilisés dans une cellule électrolytique pour l'affinage du zinc ou dans une cuve d'électrolyse pour la fusion de l'aluminium. Une cathode souple (6) comprend une pluralité de feuilles ou de queues souples d'aluminium (8) pour connecter électriquement un rail de cuve d'électrolyse à une barre omnibus d'une cuve d'électrolyse de four de fusion d'aluminium via une tête d'aluminium intermédiaire (7) et un contact de cuivre (9). Le contact de cuivre (9) est électromécaniquement connecté et combiné par une série de soudures thixotropiques (10) sur l'ensemble de la largeur du recouvrement de la tête d'aluminium (7) et du contact de cuivre (9) et entre le recouvrement entre la tête d'aluminium (7) et les queues souples de cathode (8). Un tel assemblage permet d'obtenir une conductivité électrique améliorée et une résistance d'assemblage mécanique améliorée, et ainsi d'aboutir à une amélioration de la durabilité et à une diminution du coût de fabrication.
