Abstract

L'invention concerne un tube commutateur à vide (1, 21, 41) comprenant un boîtier composé d'une première bride métallique (2, 22, 42) à travers laquelle un premier boulon de raccord (3, 23, 43) s'étend de manière étanche au vide dans le tube commutateur à vide (1, 21, 41) vers un premier contact (4, 24, 44), d'au moins une région de boîtier en matériau isolant (6, 26, 26', 26'', 46) ainsi que d'un deuxième boulon de raccord (8, 28, 48) qui s'étend de manière étanche au vide dans le tube commutateur à vide (1, 21, 41) vers un deuxième contact (10, 31, 50). L'invention vise à perfectionner un tel tube commutateur à vide pouvant être fabriqué à peu de frais en présentant une structure compacte. A cet effet, ladite région de boîtier en matériau isolant (6, 26, 26', 26'', 46) est formée par un isolateur en forme de disque. L'invention concerne également un pôle d'interrupteur (70) pour un appareil commutateur pourvu d'un tube commutateur à vide (1, 21, 41).
