Human body induction energy-saving electric shock preventing socket

Abstract

The invention provides a human body induction energy-saving preventing electric shock socket, which comprises a shell and a plug hole group arranged on the shell, wherein a human body induction circuit, a detection switch, a relay output circuit and a power supply circuit are arranged in the shell; the relay output circuit comprises a silicon controlled rectifier, which is provided with a control electrode, a cathode and an anode, the control electrode of the silicon controlled rectifier is connected with a start circuit, the cathode of the silicon controlled rectifier is connected with one end of a winding of a relay by the detection switch, the other end of the winding is earthed, and a flywheel diode is connected between two ends of the winding in parallel; the relay is provided with normally closed stationary contacts, normally open stationary contacts and a moving contact, and the anode of the silicon controlled rectifier is connected with one normally closed stationary contact and is connected to a live wire by the moving contact; and the cathode of the silicon controlled rectifier is also connected with one end of a capacitor throttling retaining circuit, and the other end of the capacitor throttling retaining circuit is connected with the normally open stationary contact in the same group with the normally closed stationary contact. When the plug hole group is electrified, the working current of the relay is only 1 / 5-1 / 10 of the rated current, thus electrical energy is greatly saved.

Description

technical field [0001] The invention relates to the safety technology of sockets, in particular to a human body induction energy-saving and electric shock-proof socket. Background technique [0002] The socket is an indispensable electrical connection device in the production and life of modern people. Most of the existing sockets directly connect the electrode contacts in the socket with the power lines, and directly contact the electrode contacts through the plugs of the electrical appliances to achieve the purpose of connecting to the power supply during use. Because the electrode contacts are charged all the time, this socket is easily touched by hands directly or indirectly, causing electric shock accidents. In addition, if the socket is misplugged with a conductor, it is also easy to cause an electric shock accident. Therefore, the safety performance of most existing sockets needs to be improved. In addition, although there are also some sockets with safety protecti...

AI Technical Summary

Problems solved by technology

Since the electrode contacts of this kind of socket are always charged, it is easy to be directly or indirectly touched by human hands, causing electric shock accidents.

In addition, if the conductor is used to insert the socket by mistake, it is also easy to cause an electric shock accident.

Therefore, the safety performance of most existing sockets needs to be improved

In addition, although there are also some sockets with safety protection functions on the market, such as the anti-shock socket circuit with patent No. CN101859964A and the intelligent anti-shock socket based on infrared detection with patent No. CN101752749A, they are often complicated in structure and high in cost by using a single-chip microcomputer system. , its own power consumption is large, so it does not meet the current environmental protection requirements for green energy saving

[0003] In summary, the existing anti-shock sockets obviously have inconvenience and defects in actual use, so it is necessary to improve them.
