Title (EN) CATHODE STRUCTURE AND ELECTRON GUN FOR CATHODE RAY TUBES
(FR) STRUCTURE DE CATHODE ET CANON ELECTRONIQUE DESTINES A DES TUBES CATHODIQUES
Abstract:
(EN) The invention relates to a cathode structure intended to be inserted into an electron gun for a cathode-ray tube. The cathode comprises a cathode body (23) on the end of which is placed an emissive pellet (26), the cathode body being held in place inside a sheath (22) by supporting means which comprise: a first series of branches (31), each branch being connected on one side to the cathode body and on the other side to an intermediate piece (30); and a second series of branches (32), each branch (32) being connected on one side to the sheath (22) and on the other side to the same intermediate piece (30).
(FR) L'invention concerne une structure de cathode conçue pour être insérée dans un canon électronique d'un tube cathodique. Cette cathode comprend un corps (23) sur une extrémité duquel on a placé une pastille émissive (26), ce corps étant maintenu en place dans une gaine (22) à l'aide de moyens de support se composant: d'une première série de branches (31) reliées chacune, d'un côté, au corps de la cathode et, de l'autre côté, à un élément intermédiaire (30), et d'une seconde série de branches (32) reliées chacune, d'un côté, à la gaine (22) et, de l'autre côté, au même élément intermédiaire( 30).
