Intelligent anti-power cord reverse connection wall socket

Abstract

The invention discloses an intelligent wall socket for preventing reverse connection of power cords, which includes a socket panel installed at the front end of the cassette, an insulating plate is slid up and down inside the rear end of the socket panel, and conductive columns are embedded at both ends of the insulating plate. The upper end of each conductive column is provided with a blind hole, and a conductive spring is installed in the blind hole on each conductive column; a magnet is fixed in the middle of the lower end surface of the insulating plate, and a plug sleeve is arranged on the socket panel below the magnet. There is an electromagnet T1 plugged in the sleeve; a ring-shaped circuit board is set on the outside of the sleeve, and the circuit board is equipped with a step-down rectifier circuit, a voltage stabilization circuit, a drive circuit, a detection module and an alarm circuit; the wall socket is used During the process, when the reverse connection of the phase line and the neutral line occurs, and after the wall socket is powered on, the wall socket can automatically disconnect the power supply of the phase line conductive socket and the neutral line conductive socket and give an alarm.

Description

technical field [0001] The invention relates to the technical field of power sockets, in particular to an intelligent wall socket that prevents reverse connection of power lines. Background technique [0002] The wall socket is usually a device installed on the wall for plugging in electrical appliances. The wall socket is fixed to the cassette when installed, and the cassette is pre-buried in the wall, and the wall socket is connected to the household. The main switch is electrically connected. In this way, when the plug of the electrical appliance is plugged into the wall socket, the wall socket can realize the power supply to the electrical appliance; Satisfy the requirement of "left zero, right fire, grounding" (that is, when the front surface of the three-hole wall socket is facing the human body, it needs to be satisfied that the conductive socket at the position of the left socket is connected to the neutral line, and it is located on the right The conductive socket ...

In this way, when the plug of the electrical appliance is plugged into the wall socket, the wall socket can realize the power supply to the electrical appliance; Satisfy the requirements of "left zero, right fire, grounding" (that is, when the front surface of the three-hole wall socket is facing the human body, it needs to be satisfied that the conductive socket at the position of the left socket is connected to the neutral line, which is located on the right The conductive socket at the position of the jack is connected to the phase line, that is, the live wire, and the conductive socket at the position of the upper jack is connected to the ground wire; for a wall socket with two jacks, when two jacks When the front surface of the wall socket faces the human body, it needs to meet the requirements that the conductive socket at the position of the left jack is connected to the neutral line, and the conductive socket at the position of the right jack is connected to the phase line, that is, the live line. ), but in the actual wiring process, the installer of the wall socket is prone to reverse the phase line and the neutral line, that is, the three-hole socket is prone to the phenomenon of "left fire and right zero". bring security risks
