AI Technical Summary
In the prior art, the buffer spring is located on the outside of the stationary conductive rod, which makes it difficult to maintain stable contact when the stationary side contact is subjected to closing impact, resulting in mechanical vibration and component deformation or fatigue fracture.
An elastic element is installed at the connection between the stationary end and the stationary end outlet seat of the arc-extinguishing chamber, and a pre-pressure is applied by a pre-compression element to compress the elastic element and form a stable buffer structure. Combined with the design of the conductive clamp and outlet seat, stability and conductivity are enhanced.
It improves the contact stability between the stationary and moving contacts, reduces mechanical vibration and component fatigue, extends service life, and lowers maintenance costs.
