Abstract

L'invention concerne une borne (1) pouvant être fixée à un fil (2) comprenant un conducteur (3) et un isolant (4) qui recouvre le conducteur (3), qui est pourvue d'une partie de contact (5) pouvant venir en contact avec une borne homologue, d'une partie de sertissage de conducteur (8) qui peut être sertie sur le conducteur (3), et d'une partie de sertissage d'isolant (9) qui peut être sertie sur l'isolant (4). La partie de sertissage de conducteur (8) comporte deux pièces de sertissage de conducteur (10) qui se font face et qui peuvent être serties sur l'intérieur. Un bord supérieur (12) d'au moins une pièce de sertissage de conducteur (10) parmi les deux pièces de sertissage de conducteur (10) comporte : un bord supérieur arrière (16) s'étendant sensiblement parallèlement à la direction longitudinale de la borne (1) ; et un bord supérieur avant (15) positionné plus près de la partie de contact (5) que le bord supérieur arrière (16), le bord supérieur avant (15) étant positionné à une position plus basse que le bord supérieur arrière (16).
