Abstract

L'invention porte sur un ensemble de fixation pour un élément de contact dans un appareillage de commutation isolé des gaz ou de l'air pour un usage à moyenne ou haute tension, lequel connecte électriquement l'élément de contact à un chemin de courant principal, et se connecte mécaniquement à une armature ou à un support par le biais d'un élément isolateur, selon le préambule de la revendication 1. Afin de réduire le temps de manipulation nécessaire au montage des pièces susmentionnées, tout en réalisant une haute performance de fixation des pièces susmentionnées, l'invention est que l'élément isolateur comporte du côté de l'élément de contact un pilote d'entrée en forme de coupe, et que l'élément de contact comporte une ouverture en contrepartie complémentaire pour la réception mécanique du pilote d'entrée depuis son côté ouvert de la section en forme de coupe, et qu'une fiche de verrouillage, pouvant être insérée depuis le côté ouvert dans le pilote d'entrée, assure la fixation mécanique de l'élément de contact sur l'élément isolateur.
