Abstract

L'invention concerne des bandes métalliques allongées (10) qui peuvent être découpées en plusieurs contacts électriques de type rivet. Les bandes (10) comprennent une tête allongée (12) et un corps allongé (14), qui forment une tête de contact et un corps de contact quand elles sont coupées sans matriçage à froid. Elles sont conçues de façon que le corps du contact soit déformé quand le contact est fixé sur une pièce telle qu'une estampeuse pour métaux. Les bandes métalliques (10) peuvent être introduites directement dans une matrice progressive utilisée pour réaliser l'estampage, puis découpées en contacts et fixées sur l'estampeuse à l'intérieur de la matrice.
