L'invention concerne une borne de connexion de conducteur (1) comprenant un boîtier en matériau isolant (2) et au moins une connexion par borne à ressort (11) dans le boîtier (2), ainsi qu'au moins un élément actionneur (4) logé de manière à pouvoir pivoter dans le boîtier (2) et adapté pour ouvrir respectivement au moins une connexion par borne à ressort (11) associée. L'élément actionneur (4) possède deux segments de parois latérales (8a, 8b) espacés l'un de l'autre qui pénètrent au moins en partie par une zone de pivot (14) dans le boîtier en matériau isolant (2) et qui sont reliés face à la zone de pivot (14) au moyen d'une traverse (5) pour former un bras de levier. Les zones de pivot (14) des segments de parois latérales (8a, 8b) espacés l'un de l'autre d'un élément actionneur (4) forment un axe de rotation (D) sur lequel l'élément actionneur (4) est supporté en rotation dans le boîtier (2). Une connexion par borne à ressort (11) associée est logée au moins en partie dans l'espace entre les zones de pivot (14) d'un élément actionneur (4). Les zones de pivot (14) possèdent des segments d'actionnement (16) adaptés chacun pour solliciter un ressort de serrage (17) associé d'une connexion par borne à ressort (11) lorsque l'élément actionneur (16) pivote d'une position de fermeture à une position ouverte. Selon l'invention, les segments d'actionnement (4) sont disposés dans les zones de pivot (14) des segments de parois latérales (8a, 8b) avec un écartement entre eux qui est inférieur à l'écartement entre les segments de parois latérales (8a, 8b), les segments d'actionnement (16) sont parallèles aux segments de parois latérales (8a, 8b) et formés d'un seul tenant avec ces derniers en créant une fente de guidage (30) respective entre un segment d'actionnement (16) et le segment de paroi latérale (8a, 8b) associé directement adjacent, et une nervure de guidage (27) respective du boîtier en matériau isolant (2) s'engage dans une fente de guidage (30) associée afin de guider l'élément actionneur (4) lors du pivotement sur un axe de rotation (D) dans la zone de pivot (14).
