AI Technical Summary
Existing surge protectors are prone to internal tripping when soldered to external circuit boards due to the melting of low-temperature solder, resulting in malfunction.
A welding anti-disengagement surge protector was designed, comprising a base, a varistor, a first electrode, a tripping mechanism, and an anti-disengagement component. By setting a plug slot and an anti-disengagement component on the base, the blocking component prevents the first electrode from separating from the protruding electrode during welding. The reflow soldering process is used to improve welding efficiency and reliability.
It effectively prevents the first electrode from disengaging from the extended electrode during welding, ensures the normal operation of the protector after welding, and improves the welding area and reliability, enhances the product's current surge resistance and miniaturization design.
