Abstract
A high-voltage electronic tube includes a housing enclosing a vacuumized space. The housing has a cylindrical metal jacket and an annular insulating disc connected vacuumtight to an inner face of the jacket. An electrode support passes through a central opening of the annular insulating disc and is connected vacuumtight to the annular insulating disc. The electrode support positions an electrode in the vacuumized space. A metal sleeve divides the annular insulating disc into two separate annular disc parts arranged concentrically to the tube axis. The metal sleeve is connected vacuumtight to the annular disc parts.
Claims13
In a high-voltage electronic tube having a longitudinal tube axis and including
- a housing enclosing a vacuumized space;
- said housing having a cylindrical metal jacket and an annular insulating disc having an outer periphery connected vacuumtight to an inner face of the jacket;
- an electrode support passing through a central opening of the annular insulating disc and being connected vacuumtight to an inner periphery of the annular insulating disc;
- and
- an electrode positioned by said electrode support;
- the improvement comprising at least one metal sleeve dividing said annular insulating disc into at least two separate annular disc parts arranged concentrically to said tube axis;
- said metal sleeve being connected vacuumtight to said annular disc parts and being at a radial clearance from said jacket.
In a high-voltage electronic tube having a longitudinal tube axis and including
- a housing enclosing a vacuumized space;
