  • High voltage electron tube base with separate dielectric fill-hole
    Patent number: 4076366
    Abstract: 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.
