Improved electric-power power supply device

Abstract

The invention discloses an improved electric-power power supply device. The device comprises a power supply socket, and an electricity connection body cooperatively connected with the power supply socket. A plug is arranged in the middle of the right end face of the electricity connection body. Two insertion plates are symmetrically arranged on front and back sides of the plug on the right end face of the electricity connection head body. A locking groove is arranged in the inner side end face of each of the insertion plates. A first guidance slope is arranged on the inner side of the right end wall of each of the locking grooves. A second guidance slope is arranged on the periphery of the right end face of each of the insertion plates. According to the invention, the device is simple in structure and high in power supply stability; occurrence of electric shock accidents in the life is effectively reduced; life safety of people is ensured; unlocking of the electricity connection head body is achieved through control of rotation of a motor; unlocking of the electricity connection head body and popping of the plug and separation of the plug from the cooperative connection with powersupply holes can be achieved simultaneously; and the electrification and power-off operation of the whole device is simple and convenient.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to an improved electric power supply device. Background technique [0002] Nowadays, the power supply of electrical equipment is basically to directly insert the plug connected to it into the power supply hole of the power supply socket, and the power supply socket and the mains connection will always be in a power-on state. Convenient, but the length of the wires between the plug and the electrical equipment is different. After the plug is inserted into the power supply hole, there is no other locking device to lock the plug. detachment, resulting in a sudden power failure of the electrical equipment, and in severe cases, it will directly cause damage to the electrical equipment. Therefore, the existing matching method between the plug and the power supply hole has an unstable power supply connection. When not in use, the plug is often pulled out from the power supply hole, wh...

[0002] Nowadays, the power supply of electrical equipment is basically to directly insert the plug connected to it into the power supply hole of the power supply socket, and the power supply socket and the mains connection will always be in a power-on state. Convenient, but the length of the wires between the plug and the electrical equipment is different. After the plug is inserted into the power supply hole, there is no other locking device to lock the plug. detachment, resulting in a sudden power failure of the electrical equipment, and in severe cases, it will directly cause damage to the electrical equipment. Therefore, the existing matching method between the plug and the power supply hole has an unstable power supply connection. When not in use, the plug is often pulled out from the power supply hole, which will cause the power supply hole to be exposed. If a child at home inserts a finger or a metal rod directly into the power supply hole, it will cause an electric shock accident, and there is a large Potential safety hazards, and when the plug is pulled out from the power supply hole, a large force needs to be applied, which is not easy to operate
