Abstract

Pour obtenir une liaison guidée entre le ressort de contact et le support de couplage lors de la fabrication de supports de couplage avec contacts à ressort pour semiconducteurs constitués par un support en plastique, un manteau en métal introduit dans le support et des ressorts de contact introduits dans le manteau on propose ce qui suit: chaque ressort de contact avant son introduction dans le manteau, lui-même introduit dans le support, respectivement chaque manteau muni de ressort de contact introduit dans l'ouverture de réception du support relative à la partie du manteau fixe par rapport au support, sont tournés autour de leurs axes longitudinaux dans un but d'alignement. Ainsi la position par rapport à la branche du ressort et du canal polygonal formé est identique pour chaque pièce de ressort à contact introduite qui suit la pièce et pour celle qui la précède. La partie en ressort de contact qui est guidée lors de la rotation et lors du guidage assure au moins temporairement sa position relative en liaison forcée avec le manteau.
