Abstract

L'invention concerne un segment de boîtier (34) pour un point de raccordement (42) de systèmes de barre omnibus dans un réseau de distribution électrique. L'invention vise, d'une part, à fournir aux points de raccordement (42) de deux systèmes de barre omnibus un dispositif d'application d'une pression d'appui sur le point de raccordement (42) des systèmes de barre omnibus et, d'autre part, à permettre un blindage du point de raccordement (42) qui soit compact et facile à monter. A cet effet, une paroi extérieure (38) du segment de boîtier exerce simultanément une pression d'appui sur le point de raccordement (42) des systèmes de barre omnibus au moyen d'éléments de pression (54, 56), de sorte que le serrage du point de raccordement (42) et le montage de la paroi extérieure (38) du segment de boîtier (34) représentent une étape de travail unique. La paroi extérieure (38) est formée par un volet (38) à la fermeture duquel une pression d'appui s'exerce sur le point de raccordement (42).
