Abstract

The invention discloses an improved structure of a ceramic vacuum relay. The improved structure comprises a ceramic vacuum sealing cover, and a moving contact point and a static contact point which are arranged in the ceramic vacuum sealing cover. A shielding cover is arranged between the ceramic vacuum sealing cover, and the moving contact point and the static contact point which are arranged in the ceramic vacuum sealing cover so that the service life of an electric load of the relay can be effectively enhanced without generating adverse influence on performance of the relay. Meanwhile, one step is arranged in the ceramic vacuum sealing cover, and the step is provided with one metal layer so that fixing of the shielding cover on the ceramic vacuum sealing cover can be facilitated.

Description

technical field [0001] The invention relates to an improved structure of a ceramic vacuum relay. Background technique [0002] At present, the existing ceramic vacuum relays on the market are composed of a vacuum chamber, a transmission part, and a coil. The ceramic inner surface reduces the insulation resistance of the relay, thereby affecting its life. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an improved structure of a ceramic vacuum relay, which effectively improves the electrical load life of the relay. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: an improved structure of a ceramic vacuum relay, including a ceramic vacuum sealing cover and a moving contact and a static contact arranged in the ceramic vacuum sealing cover, in the ceramic vacuum sealing cover A shielding cover is arranged between the sealing cover and the moving con...
