Anti-loosening and anti-short circuit socket

Abstract

The invention discloses an anti-loosening and anti-short circuit socket, which comprises a socket and a plug, wherein the socket comprises a square shell embedded in a wall body, and is characterizedin that two pairs of clamping reeds are fixedly installed on the inner wall of the rear side of the shell, the two pairs of clamping reeds are electrically connected with a live wire and a zero wire respectively, the front end of the shell is provided with jacks in the corresponding positions of the two pairs of clamping reeds, the plug comprises a base body and two inserting pieces embedded in the front end of the base body, the two inserting pieces can be inserted into the corresponding pairs of clamping reeds through the inserting holes respectively, the front end of the shell is provided with two strain holes between the two jacks, the inner wall of each strain hole is provided with an iron core, and the outer walls of the two iron cores are jointly wound with a first connecting wire.The socket has the advantages that two different modes of response are performed by using the same mechanism according to two conditions mentioned in the background technology, a corresponding solution is provided no matter whether the plug is loosened or the power of an electric appliance is too high, and dangerous cases are avoided.

Description

technical field [0001] The invention relates to the technical field of sockets, in particular to an anti-loosening and anti-short circuit socket. Background technique [0002] As a power medium that is often used in our daily life, sockets are particularly critical for their convenience and safety. However, in the course of long-term use, it was found that in order to prevent the plug from loosening and falling off during the use of electricity, there are usually two sets of elastic reeds inside the socket for clamping the plug, but as the reeds are used for a long time , the friction loss with the plug is serious, the structure changes, the clamping effect cannot be achieved, and loosening and poor contact are more likely to occur, resulting in an increase in the contact resistance of the two sets of reeds, heat accumulation, short circuit, and a fire may occur in severe cases; In addition, it can be seen from the formula I=P / U that when the voltage is constant, when the s...

However, in the course of long-term use, it was found that in order to prevent the plug from loosening and falling off during the use of electricity, there are usually two sets of elastic reeds inside the socket for clamping the plug, but as the reeds are used for a long time , the friction loss with the plug is serious, the structure changes, the clamping effect cannot be achieved, and loosening and poor contact are more likely to occur, resulting in an increase in the contact resistance of the two sets of reeds, heat accumulation, short circuit, and a fire may occur in severe cases; In addition, it can be seen from the formula I=P / U that when the voltage is constant, when the socket is connected to a high-power electrical appliance, such as an electric furnace, the current of the transmission line will increase, and by Joule's law Q=I 2 Rt, it can be seen that there will be significant heat on the wire, and sometimes the insulation of the wire may be burned, which will also cause a fire
