Abstract

Selon l'état de la technique, il existe dans les bornes électriques à vis à torons un rapport peu optimal entre la force de vissage et la force de pression des torons, en particulier en cas de sections transversales variables de conducteurs en torons. L'invention propose alors de former au moins un élément participant au processus de vissage de manière sphérique. Une vis de borne (1) possède donc, adjacente à sa section d'extrémité (11) en forme de cône, une section sphérique (14) et/ou un corps de contact (2) dans lequel la vis de borne (1) est vissée possède une forme sphérique après un renflement (241) dirigé vers l'intérieur, au moins par endroits. Lors du vissage, la vis de borne (1) sépare les torons (31) par la pointe (111) de sa section d'extrémité (11) en forme de cône avec seulement la plus petite force possible, les répartit de manière homogène et les presse avec une force maximale, et en particulier indépendamment de la section transversale des conducteurs en torons, au moins à une position dans un angle optimal par rapport au renflement (241), de sorte que le rapport entre la force d'actionnement et la force de pression est optimisé.
