Anti-short-circuit power-off device

By introducing a short-circuit protection device into the socket, a strong magnetic field generated by a conductive coil drives an iron slider to move and quickly cut off the circuit, thus solving the risk of circuit burnout and fire when the socket is short-circuited and improving safety.

AI Technical Summary

Technical Problem

Existing sockets lack short-circuit protection devices, which poses a high risk of wiring burnout or fire in the event of a short circuit.

Method used

A short-circuit protection and power-off device was designed. It uses a conductive coil to generate a strong magnetic field to drive the iron slider to move, which in turn causes the locking block to disengage from the locking groove. The circuit is quickly cut off through an elastic reset structure. The device includes components such as a first fixing rod, a pressing post, a locking groove, a first spring, a limiting plate, a moving plate, an elastic conductive sheet, a second fixing rod, an iron slider, a moving post, a locking block, and a second spring.

Benefits of technology

It enables rapid circuit disconnection in the event of a short circuit, reducing the risk of overheating or fire and improving safety.

Abstract

The utility model discloses an anti-short circuit power-off device, which comprises a socket main body, one side of the socket main body is fixedly connected with a protection box, the inner bottom of the protection box is fixedly connected with a fixed seat, the upper surface of the fixed seat is fixedly connected with two third wires, and the inner bottom of the socket main body is fixedly connected with two contact pieces. Through the arrangement of the limiting plates, the moving plates, the elastic conducting strips, second fixing rods, iron sliding blocks, moving columns, clamping blocks, second springs and the like, the iron sliding blocks drive the clamping blocks to move through the moving columns and compress the second springs, then the pressing columns are pushed to move upwards under the elastic release of the first springs, the two limiting plates abut against the inner top of the protection box, and therefore the protection box is protected. The pressing column drives the elastic conducting strip to be separated from the first power connection block and the second power connection block through the moving plate, the circuit can be rapidly cut off, and the circuit overheating or fire risk caused by power-off delay during short circuit is reduced.
