Safety socket for fire-fighting alarm host

Abstract

The invention discloses a safety socket for a fire-fighting alarm host. The safety socket comprises a socket panel, a socket base and a jack panel; a protection lock block and a connecting-inserting piece assembly are arranged in the interior of the safety socket; the connecting-inserting piece assembly can switch between a connecting state and a disconnecting state in a terminal inserting direction of a plug; the connecting state is performed when the connecting-inserting piece assembly, the protection lock block and the jack panel move downwards integrally; the connecting-inserting piece assembly, the terminal of the plug, and the inserting pieces on the socket base are electrically connected; the disconnecting state is performed when the connecting-inserting piece assembly, the protection lock block and the jack panel move upwards integrally, and the connecting-inserting piece assembly and the inserting pieces on the socket base are disconnected. The safety socket has the beneficial effects that the abnormal electric connection of the existing socket is effectively prevented, and the risk of electric shock is greatly reduced, so that the safety socket is safe and reliable, and worthy of wide popularization.

Description

technical field [0001] The invention relates to a safety socket, in particular to a safety socket used for a fire alarm host. Background technique [0002] Nowadays, all walks of life in society need to use electricity. The supply of electricity is transmitted from the power plant to the substation, and then sent to the power line at the user end. The end of the power line is usually equipped with a power socket. Users use various electronic devices. The plug is inserted into the socket, so that the electronic device is electrically connected to the power line to obtain power. [0003] Safety sockets are also used in fire alarm hosts. Generally speaking, the indoor power supply is single-phase. When the two terminals of the plug are inserted into the socket, one of the terminals of the plug will be electrically connected to one wire (live wire) of the power line, and the other One terminal is electrically connected to the other wire (neutral wire) of the power line. Theref...

Problems solved by technology

[0004] Sockets in the prior art generally have their own elasticity of the metal contacts and are connected to the plug. The contacts of the socket are directly connected to the power line, the neutral line is located on the left, and the live line is located on the right. Safe and reliable, for example: when an electrical appliance fails, it is easy to cause a short circuit or overload of the line, which will cause a fire. If liquid accidentally spills into the socket hole, it will also cause a short circuit or leakage of electricity; Falling into the socket hole will also cause electric shock accidents; in addition, children at home often have tragedies caused by touching the socket hole with their fingers and getting an electric shock due to their vague safety awareness.

The above-mentioned situations are very common in life, so their potential dangers are relatively large, the consequences are serious, and they pose a relatively large threat and bad influence to people's property and life safety.
