Abstract

Objectif de l'invention. Réduire la charge d'un mécanisme d'ouverture-fermeture pour un dispositif contacteur à double rupture et pour miniaturiser le dispositif contacteur.Un premier contacteur 2 mobile, qui a un contact 2a mobile à une extrémité, est supporté en rotation par un arbre 3 de point de support à l'autre extrémité, et est entraîné en ouverture/fermeture par un mécanisme d'ouverture/fermeture, un contacteur 5 fixe qui a un contact 5a fixe à une extrémité et est formé en ayant une borne 6 à l'autre extrémité, et un deuxième contacteur 7 mobile qui a un premier contact 7a mobile à une extrémité et un deuxième contact 7b mobile à l'autire extrémité, et est supporté en rotation par un arbre 8 de point de support à une position située entre le premier contact 7a mobile et le deuxième contact 7b mobile sont agencés suivant une forme en S. Le premier contacteur 2 mobile est sollicité en direction du deuxième contacteur 7 mobile par un ressort 11 de réalisation de contact et le deuxième contacteur 7 mobile est sollicité en direction du premier contacteur 2 mobile et du contacteur 5 fixe par un ressort 12 de réalisation de contact. Lorsqu'un grand courant tel qu'un courant de couit-circuit passe, les premier et deuxième contacteurs 2 et 7 mobiles sont tournés à l'encontre des ressorts 11 et 12 de réalisation de contact par des forces de répulsion électromagnétiques qui agissent sur des courants passant à travers les contacteurs 2, 5 et 7, les contacts étant séparés les uns des autres avant qu'une action d'ouverture ait lieu du mécanisme d'ouverture-fermeture.
