Abstract

L'invention concerne un éclateur à haute puissance encapsulé, résistant à la pression, fermé non hermétiquement, à la construction de base à symétrie rotationnelle comprenant deux électrodes principales opposées espacées, un boîtier extérieur métallique à bord rabattu côté frontal, au moins une électrode de déclenchement, un espace de décharge ainsi que des contacts de raccordement electriques, de préférence disposés du côté frontal, pour les électrodes principales et des corps d'encapsulation et de centrage des électrodes principales destinés à fixer les électrodes principales l'une par rapport à l'autre et par rapport au boîtier extérieur. Conformément à l'invention, dans une première forme de réalisation, un fil isolé ou de préférence un conducteur en forme de ruban est inséré, pour établir le contact avec l'électrode de déclenchement, dans un espace en forme d'interstice entre un côté extérieur de l'une des électrodes principales et le côté correspondant du corps d'encapsulation et de centrage des électrodes principales, l'extrémité de raccordement extérieure du conducteur étant accessible dans la zone du contact de raccordement côté frontal de l'électrode principale concernée et l'extrémité intérieure dénudée du conducteur étant en liaison électrique avec l'électrode de déclenchement. Dans une deuxième forme de réalisation, pour établir le contact avec l'électrode de déclenchement, l'un des corps d'encapsulation et de centrage des électrodes principales est réalisé isolé et présente un orifice qui s'étend dans le sens longitudinal axial, une pièce de contact flexible se trouvant dans cet orifice, dont l'extrémité intérieure est en contact avec l'électrode de déclenchement et dont l'extrémité extérieure est accessible dans la zone du contact extérieur correspondant côté frontal pour réaliser le branchement électrique.
