BLOCKING CAPACITOR FOR USE IN A MICRO-GENERATOR OF A MICROWAVE OVEN

摘要

PURPOSE: A blocking capacitor of a ultra high frequency oscillator tube for microwave range is provided to reduce manufacturing costs by improving a structure of a blocking capacitor. CONSTITUTION: An upper surface of an upper portion of a capacitor is polished and a metalizing face is formed thereon. A metal cap(300) is loaded on the remaining part of the capacitor. The metal cap(300) comprises an inner cylindrical portion(320) and an outer cylindrical portion(340) and a bottom plate(360) for connecting the inner cylindrical portion(320) with an outer cylindrical portion(340). A height of the inner cylindrical portion(320) is higher than a height of the outer cylindrical portion(340). An end portion(342) of the outer cylindrical portion(340) is bent and overlapped with the metal rising face(210). A discontinuous portion is formed between a heater housing(190) and an upper end portion of the inner cylindrical portion(322).
