Abstract
PURPOSE:To obtain a cathode structure with long life and high reliability by fixing metal wires at the closed portion of a metal sleeve on the outside from the outer periphery of a metal cap. CONSTITUTION:After a cap 2, a metal sleeve 3 and metal wires 6 are integrally fixed, an impregnated cathode 1 is stored in the cap 2, and the cap 2 and the impregnated cathode 1 are fixed by soldering. Ends of the metal wires 6 are soldered and fixed to a cathode support tube provided on the through hole of a ceramic insulating substrate, a heater 4 is inserted into the sleeve 3 to complete an impregnated cathode structure. Since the cap 2 and the metal sleeve 3 can be directly connected on the flat plane and two metal wires 6 can be directly connected on the metal sleeve 3, the connection strength of the constituting components 2, 3, 6 is remarkably improved, and the cap 2 and the metal sleeve 3 are directly connected at the wide area of their bottoms, thus the thermal conduction is good, and the stable electron emission characteristic is obtained.
