AI Technical Summary

Technical Problem

Existing secondary power supply sockets are prone to problems such as jamming, poor contact, or damage after prolonged use.

Method used

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.

Benefits of technology

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.

Abstract

A safety socket designed to prevent loosening after repeated plugging and unplugging, belonging to the field of socket technology, addresses the problem of secondary power sockets becoming stuck after prolonged use, leading to poor contact or damage. The invention includes a panel with an outer compartment fixedly mounted on its side wall. A pair of compression limiting components are symmetrically fixedly mounted on the side wall of the outer compartment's inner cavity. A pair of conductive elements are symmetrically fixedly mounted on the side wall of a sliding component facing the socket. A T-shaped locking block is also fixedly mounted on the side wall of the sliding component away from the socket. A locking component is fixedly mounted on the side wall of the inner cavity facing the T-shaped locking block. An indicator component and a protective component are fixedly mounted on the side wall of the panel's inner cavity. This invention eliminates the complex mechanisms of traditional secondary power sockets such as wedge-shaped sliders and levers, employing a sliding spring and locking structure to reduce the problems of sticking, loosening, poor contact, or damage after prolonged plugging and unplugging.
