Human body safety socket

Abstract

The invention relates to a human body safety socket which comprises a socket body and is characterized by also comprising an AC (alternating current) branch detection circuit for monitoring load or electric leakage of the socket, a current detection transformer for detecting the current of the socket, an electric leakage detection coil and an impedance pre-detection circuit adopting a multivibrator, which are respectively connected with a central function controller through an amplifying, rectifying and shaping circuit, wherein the current detection transformer and the electric leakage detection coil are used for detecting the current of the socket; the central function controller is connected with a first relay responsible for the on / off of test ends of the AC current branch detection circuit, the current detection transformer and the electric leakage detection coil and a second relay responsible for conversion work of connecting a mains supply to the socket. According to the invention, no electric shock of people can be realized through the bare socket, a user is ensured to find out the power capacity of the site to the electrical appliances or the electrical appliances in failure as soon as possible; and moreover, the user does not need to perform switching-on operation in case of emergency, and just needs to withdraw the electrical appliances, so that the circuit can return to the condition that the idle socket does not carry the strong current, and the human body safety socket has better practical value.

Description

technical field [0001] The invention relates to the technical field of electricity safety, in particular to a human body safety socket. Background technique [0002] Today, circuit breakers and leakage switches are widely used in various indoor occasions such as living rooms, companies, schools, etc., as well as commercial power strips and some electrical appliances' own protection devices, which are used to prevent overcurrent or leakage of loads on power supply lines. Protection, effectively reducing personal injury and economic property loss. The protection performance of circuit breakers and leakage switches is known for their rapid shutdown. When the current somewhere in the line exceeds the nominal current value, they will immediately trip and cut off the live wire. When the electrical appliances in the line run without phase or someone gets an electric shock, the leakage switch will act to cut off the live wire and the neutral wire. When the user evacuates the faulty...

Problems solved by technology

[0003] For this set of civilian products, there is still a safety hazard at present, that is, the idle socket is still charged with strong electricity. If some naughty children's fingers, metal objects are inserted or the damaged socket makes the user use it, it is inevitable that the user will inevitably get an electric shock. Although the national compulsory certification leakage After the switch is recognized, it will trip in a short time, which will not cause harm to the human body, but the electric shock current is relatively large, and people will still feel that they have been electrocuted, which will cause psychological shadows.
