Socket Wiring Protection Printed Circuit Board

Abstract

The invention provides a printed circuit board for wiring protection of a socket, particularly relates to a power supply protection device for socket detection and belongs to the technical field of power supply protection. The power supply protection device is installed on a power utilization device, connected between a triangle socket and the power utilization device and is serially connected with a power line of the power utilization device. The power supply protection device is used for detecting the wiring line sequence of the triangle socket and automatically introducing the triangle socket into the power utilization device when the detection is passed. According to the invention, faults of the power utilization device caused by wiring mistakes of the triangle socket can be reduced; difficulty in checking a specification for a protection detection jack by a user is released; an overvoltage protection function is added; and electromagnetic interferences are filtered; power supply security of the power utilization device is ensured from multiple aspects; and user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power supply protection, in particular to a socket wiring protection printed circuit board, in particular to a socket detection power supply protection device. Background technique [0002] Nowadays, there are more and more household and industrial electrical appliances. For safety considerations, the plugs of general electrical appliances use triangular plugs to connect to the triangular sockets of the power distribution line, and the middle jack of the triangular socket is a ground jack. However, in the power distribution network we come into contact with in real life, the middle ground jack of many buried wall triangular sockets does not have a ground wire, or does not follow the socket line sequence specified in the national standard "left zero right fire middle ground wire" In this way, the original shell of the electrical equipment at the beginning of the design lacks grounding protection; in additi...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to carefully understand the meanings of different combinations of multiple indicator lights in the manual, that is, whether the socket is missing a ground wire or the fire and neutral wires are reversed, etc. For presbyopia or illiterate and literal comprehension ability It is difficult for poor people to operate correctly

[0005] 2. It is only a movable detection plug, without power supply capability, so if you cannot change a triangular socket for movable electrical equipment or movable tool equipment, let everyone carry such a detection plug to test it, both It is easy to forget to carry it if the time is delayed, and if a person is in a hurry and directly plugs in the electrical equipment and forgets to check the grounding or fire and neutral wires of the socket, it is easy to cause safety hazards

[0006] 3. The protection detection plug does not provide lightning protection and overvoltage protection functions for electrical equipment

[0007] 4. The protection detection plug does not provide power filtering function
