AI Technical Summary
Existing secondary power supply sockets are prone to problems such as jamming, poor contact, or damage after prolonged use.
It adopts a sliding spring and snap-fit structure, combined with conductive parts and snap-fit components with adjustable preload design, abandoning the traditional wedge slider and lever mechanism. Secondary power supply is achieved through the cooperation of sliding components and snap-fit components, and it is equipped with indicator components and protective components to prevent misoperation.
It effectively reduces the problems of socket jamming and poor contact caused by repeated plugging and unplugging, ensures that the circuit is connected only when the plug is fully inserted and disconnected when unplugged, and has a self-locking function to prevent misoperation, thus improving safety and reliability.
