Abstract

PURPOSE:To prevent the discharge by placing a heat-resistant supporting lead between an insulative base for holding a grid electrode and a terminal fixed at the end of a neck section thereby decreasing the spring factor of a contactor. CONSTITUTION:One end of a rod-shaped lead 10 made of a heat-resistant metal is burried at the end section of an insulative base 5 for holding a grid electrode of an electron gun (G), while the other end of said lead 10 is jointed to a terminal 2 burried at the end of the neck section of a casing 1. Then an inner lead 4 is connected to each grid electrode while contactors 9a, b fixed to the fourth grid electrode 6 is contacted with a duck 8. Consequently the spring factor of the contactor 9 can be decreased to reduce the cutting of the duck section 8 resulting in the prevention of the discharge.
