Abstract

PURPOSE: To prevent a degree of vacuum in the tube from being lowered due to a melting of brazing material in the hermetically sealed portion, and enable a construction of shorter stem, by providing a tongue-shape part, having a fold, in the eyelet flange unit soldered to outer end face of the stem insulating base unit.
CONSTITUTION: A hermetically sealing is processed by a metallic eyelet 15, 16, in which a stem insulating base unit 1 of cup-shape, consisting of ceramic, and conductor wires 3, 4, penetrating through its bottom plate part 2 and consisting of molybdenums, are made brazing to the outer end face of the bottom plate part 2. To the flange units of these eyelets 15, 16, are respectively provided tongue-shaped parts 17, 18 for use as terminals, simultaneously at the belly portions of these tongue- shaped parts 17, 18, are formed many folds 19, 20 of a corrugated cross section, thereby to impart elasticity. In such construction, a shorter stem can be formed without causing the brazing material to melt or soften when magnetrons are manufactured, and the sealed part can be protected with a buffer action provided against the stress from an external lead wire 21.
