Stable type power supply plugging-connection device

Abstract

The present invention discloses a stable type power supply plugging-connection device. The device includes a plug portion and a socket portion; the plug portion is connected with a power-using devicethrough a cable; a plugging groove is formed at the front end surface of the socket portion; the plug portion can be plugged into the plugging groove so as to be in matched connection with the plugging groove; a first power connector is arranged at the middle of the rear end surface of the plug portion; a front locking groove and a rear locking groove which extend along a left-and-right directionso as to pass through the plug portion and are symmetrically arranged in a front-and-back direction are formed in the plug portion; a power plugging hole which is in matched connection with the firstpower connector is formed at the middle of the rear end wall of the plugging groove; and a left through sliding groove and a right through sliding groove which are communicated with the plugging groove are symmetrically formed in the left end wall and right end surface of the plugging groove respectively. According to the whole device, by means of one driving motor, the locking and unlocking of the plug portion can be completed, and the energization and de-energization of the power plugging hole can be completed, and therefore, operation is simple and convenient. The use of the device is saferand more stable, and the power supply stability of the device is high.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to a stable power supply plug-in device. Background technique [0002] At present, the use of electrical equipment is to directly insert the plug connected to it into the power supply hole of the socket to connect to the power supply. The connection between the power supply socket and the power supply will always be in a power-on state. The lengths of the power cables between the electrical equipment are different, and there is no other locking device to lock the plug after the plug is inserted into the power supply hole. When the power cable is kicked, the plug will be separated from the power supply hole. As a result, the sudden power failure of the electrical equipment may even directly cause the burning of the electrical equipment. Therefore, there is a potential safety hazard of unstable power supply connection in the existing cooperation between the plug and the power supp...
