Abstract

L'invention concerne un support (24) destiné à au moins deux barres conductrices (25). Le support de barres conductrices comprend deux éléments supports (31, 32) séparés par une ligne de joint (33) et (31, 32), présentant du côté de la ligne de joint (33) des évidements à moitié ouverts (35, 36) destinés à former des logements individuels (34), lesdits éléments supports (31, 32) peuvent être positionnés de façon à ce que les logements individuels (34) soient décalés dans une première direction transversale (27) tout comme dans une deuxième direction transversale (28) des barres conductrices, et un élément support (31) présentant des ergots (55) qui s'emboîtent dans l'autre élément support (32). L'invention vise à permettre une adaptation à différents profils de barres conductrices par le remplacement d'un seul élément support. A cet effet, respectivement un ergot (55) d'un élément support (32) s'emboîte dans un évidement (35) à moitié ouvert de l'autre élément support (31) de telle façon qu'il forme au moins une section d'un côté (56) s'étendant perpendiculairement à la deuxième direction transversale (28) des barres conductrices pour délimiter les logements individuels (34).
