Intelligent wall socket capable of preventing reverse connection of power line

Abstract

The invention discloses an intelligent wall socket capable of preventing reverse connection of a power line, which comprises a socket panel arranged at the front end of a cassette. An insulating plateis connected inside the rear end of the socket panel in an up-and-down sliding manner, conductive columns are embedded into the two ends of the insulating plate, a blind hole is formed in the upper end of each conductive column, and a conductive spring is arranged in the blind hole in each conductive column. A magnet is fixed in the middle of the lower end surface of the insulating plate, a plugbush is arranged on the socket panel below the magnet, and an electromagnet T1 is inserted into the plug bush. The plug bush is sleeved with an annular circuit board, and the circuit board is providedwith a step-down rectification circuit, a voltage stabilizing circuit, a drive circuit, a detection module and an alarm circuit. In the using process of the wall socket, when the phase line and the zero line are reversely connected, after the wall socket is powered on, the wall socket can automatically cut off the power supply of a phase line conductive socket and a zero 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 ...
