Abstract

L'invention concerne un rail de raccordement constitué d'un profil plein (11) doté de premières surfaces d'appui (12, 13) et de deuxièmes surfaces d'appui (14, 15) pour son support dans la baie (21, 22) de la paroi arrière d'un boîtier (2). Les deuxièmes surfaces d'appui (14, 15) comportent des prolongements (16, 17) pour la fixation de conducteurs plus longs, ces prolongements étant parallèles et façonnés, par exemple dans le cas de disjoncteurs à basse tension, pour fonctionner comme connecteurs mâles s'intégrant dans des connecteurs femelles fixes. La fixation des câbles conducteurs flexibles conduisant aux contacts de commutation (10) mobiles et la fixation des contacts de commutation (5) fixes sont réalisées par des saillies (18, 23) correspondantes.
