Abstract

Pour pouvoir réaliser en une seule opération le brasage de toutes les pièces du boîtier, y compris du blindage de forme tubulaire, d'un interrupteur à vide destiné aux contacteurs basse tension, le capuchon métallique (9) abritant les deux contacts (1, 2) et réalisés en cuivre argenté, doit, sur le côté destiné à être brasé avec la face de l'isolateur ayant la forme d'un cylindre creux (12), avoir un bord (9) structuré (10, 11) sur toute la circonférence. Le blindage tubulaire (16) doté d'une bordure (17) en forme de bride, est ainsi maintenu sur la même face de l'isolateur (12) grâce à des ergots d'écartement (20) réparties sur la circonférence de ce dernier.
