HIGH VOLTAGE ELECTRON TUBE BASE WITH SEPARATE DIELECTRIC FILL-HOLE

摘要

HIGH VOLTAGE ELECTRON TUBE BASE WITH SEPARATE DIELECTRIC FILL-HOLE of the Invention The base comprises a tubular housing adapted to fit over the exhaust tubulation of an electron tube stem, and a wafer flange extending outwardly from the open end thereof. The flange is apertured to receive an array of conductors of the stem. A recess is provided in the wafer flange facing the stem and a passageway communicating therewith is provided through the base separate from the housing cavity for the purpose of injecting a dielectric material into the recess around some of the stem conductors. The passageway may, e.g., be through the flange or in the housing wall. A shoulder is provided on the recessed face of the wafer flange to provide relief for random protuberances on the periphery of the stem to permit non-tilted mounting of the base on the stem.
