No-spark switching apparatus and electric-shock-preventing intelligent socket

Abstract

The invention relates to a no-spark switching apparatus and an electric-shock-preventing intelligent socket. The no-spark switching apparatus comprises one or more groups of relays, an anti-parallel controllable semiconductor module and a trigger circuit, wherein a power supply is connected between each group of the relays in parallel; each group of the relays comprise two relays; and the electric-shock-preventing intelligent socket comprises a socket body, a plugging detection apparatus and a control system. By adoption of the electric-shock-preventing intelligent socket, the problem existing in power utilization safety of the existing socket is effectively solved; meanwhile, the problem of an arc discharge phenomenon generated when a plug is inserted or pulled out from a socket in the prior art, and the problem of insufficient driving capability by taking the relay as a main switch are solved at the same time; according to the electric-shock-preventing intelligent socket, when a finger is in contact with a metal pin in the plug carelessly during inserting or pulling out the plug from the socket, an electric shock phenomenon does not occur; and when the socket is not in use, when a metal conductor is in contact with a live wire or a zero line of the power supply independently or concurrently, an electric shock accident does not occur.

Description

Technical field [0001] The invention belongs to the technical field of smart household appliances, and particularly refers to a non-spark switch device and an electric shock-proof smart socket. Background technique [0002] Sockets or power strips can be seen everywhere in homes, offices and other places, and their function is to extend the power interface, extend the power line or provide a power interface for electrical appliances. Since the advent of sockets, whether the current mainstream socket products are three-pin sockets or two-pin sockets, the internal copper is still live after the plug is pulled out, so it is easy to cause electric shock accidents, especially the number and proportion of children's electric shock accidents taller and taller. [0003] In order to prevent children’s electric shock accidents, the sockets currently used in children’s playgrounds have been mandated to have a safety protective door structure. The protective door structure used on the current...
