Abstract

L'invention concerne les tubes électroniques à grille en graphite pyrolytique. La connexion de la grille 1 avec la partie supérieure du mât conducteur central 5 est réalisée par l'intermédiaire d'une cloche 6 en graphite pyrolytique elle aussi, dont la jupe conique est découpée en lamelles, et qui est fixée par son fond sur le disque 5.1. solidaire du mât. Application notamment aux lampes triodes de puissance des émetteurs radioélectriques.
