ABSTRACT:
Disclosed is a vacuum switching tube comprising a hollow insulator and a cap closing off the insulator adjacent to its circumference at one end thereof. The cap is connected to the insulator by a joint. A shaped body covers the joint and is spaced therefrom. The space between the shaped body and the joint is filled with a bonding agent. Thereby, the joint is mechanically reinforced. The shaped body and the bonding agent substantially increase the break-off force between the cap and insulator when the vacuum switching tube is firmly clamped at one end during operation.
