Abstract

L'invention concerne une connexion par fiches haute tension (1) pour la connexion électrique amovible de composants haute tension, notamment d'un système d'entraînement électrique d'un véhicule motorisé, comportant un câble de puissance (2) respectivement pourvu d'un contact à fiche (3a, 3b) sur ses deux extrémités. Lorsque les contacts à fiche sont enfichés, le câble de puissance est connecté mécaniquement et mis en contact électrique avec un contre-contact côté composant (6a, 6b). Une position de pré-encastrement est affectée à chaque contact à fiche côté câble (3a, 3b). Dans cette position, le contact électrique (4a, 7a; 4b,7b) est ouvert et la connexion mécanique est sécurisée, celle-ci ne pouvant être déverrouillée que lorsque les deux contacts à fiche côté câble (3a, 3b) sont mis en position de pré-encastrement.
