Abstract

L'invention concerne un dispositif destiné à relier de manière électriquement conductrice les conducteurs électriques principaux (4, 5, 6, 7) d'un câble pour courants forts avec des conducteurs électriques de dérivation (13) qui les prolongent, composé d'un bâti de bornes en matériau isolant, construit à partir de pièces assemblées qui, dans la position de montage, délimitent entre elles un espace central de réception destiné à recevoir le conducteur principal. Le bâti de bornes se compose de deux demi-coques (1, 2) pouvant être assemblées, qui sont juxtaposées en position de montage et dans lesquelles sont disposés vers l'extérieur et en direction de l'espace de réception (3) des espaces partiels (11) ouverts servant chacun de guide pour des éléments de contact (12) grâce auxquels, dans un état de montage, une liaison électriquement conductrice est établie entre un conducteur principal et un conducteur de dérivation et servant également chacun au placement d'un conducteur de dérivation (13). Chaque espace partiel (11) est associé à une pièce de pression (14) faite dans un matériau isolant qui est montée mobile dans au moins une rainure de guidage (15) orientée radialement sur l'une des demi-coques (1, 2) et qui, dans la position de montage, est positionnée en dehors du conducteur de dérivation (13) considéré. Autour des deux demi-coques (1, 2) est placé un élément de serrage (16) reposant sur les pièces de pression (14).
