Abstract

The invention discloses a closed switch tube, comprising an insulator (310), a first conductor (320), a first support (330), a second conductor (340) and a third conductor (370). One end of the second electrical conductor (340) is disposed in the cavity formed by the insulator (310), the first electrical conductor (320) and the first support (330) and can be connected with the The first conductor (320) is contacted or separated, characterized in that the third conductor (370) is sleeved on the outside of the insulator (310) and is fixedly connected with the second conductor (340). A second elastic member (380) is arranged between the third electrical conductor (370) and the first support member (330), and the closed switch tube of the present invention is not affected by external force, and the internal conductive members are always in a constant state. Open state, can meet different applications.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a closed switch tube. Background technique [0002] In the high and low voltage distribution network, the use of vacuum switches occupies an absolute advantage in places where high breaking and explosion-proof are especially required. The core component of the vacuum switch is a closed switch tube, or a vacuum interrupter. Currently, it generally includes an upper cover and a ceramic seat. , bottom cover, moving contact, bellows. [0003] like figure 1 Shown is a closed switch tube structure in the prior art. The closed switch tube structure includes an upper casing 01, an insulator 02, a bellows 03, a moving contact 04, a bottom cover 05 and a static contact 06, so The insulator 02 is arranged between the casing 01 and the bottom cover 05, and the casing 01 is welded and fixed with the insulator 02 and the bottom cover 05 respectively to form a closed...
