Electric connection coupler, socket thereof and automatic springback mechanism

Abstract

The invention discloses an electric connection coupler, a socket thereof and an automatic springback mechanism. The automatic springback mechanism is installed in the socket of the electric connectioncoupler. The socket is provided with an upper cover, a lower housing, a rotatable protective cover arranged between the upper cover and the lower housing, and a first electrode; the upper cover is provided with a guide groove used for guiding a plug of the electric connection coupler to rotate to a conductive position from an initial position by a preset angle; the protective cover is provided with a plug hole corresponding to a second electrode on the plug; and the second electrode can be inserted from the plug hole and is electrically connected with the first electrode when the plug is rotated to the conductive position. The automatic springback mechanism comprises an elastic piece, wherein one end of the elastic piece is installed on the upper cover, the other end of the elastic pieceis installed on the protective cover, and the elastic piece has reset force capable of resetting the plug which is not rotated to the conductive position to the initial position. Safe operability, reliable connectivity and stable usability are achieved.

Description

technical field [0001] The invention relates to an automatic rebound mechanism, a socket and an electrical connection coupler with the same. Background technique [0002] A current rotating conductive electrical connection coupler mainly includes a plug and a socket. After the plug is inserted into the socket, the plug is rotated in one direction to a specified position to make the electrodes on the plug and the socket. The electrodes are fully electrically connected for a safe energized connection. However, for this kind of electrical connection coupler, sometimes because of the wrong operation of the user, for example, the plug is not rotated to the designated position and the plug is released, at this time, the electrodes on the plug may be partially in contact with the electrodes on the socket (but not full contact), resulting in the entire electrical circuit being in a virtual connection state. If the electrical connection coupler is used in this virtual connection st...

Problems solved by technology

However, for this kind of electrical connection coupler, sometimes because of the wrong operation of the user, for example, the plug is not rotated to the designated position and the plug is released, at this time, the electrodes on the plug may be partially in contact with the electrodes on the socket (but not full contact), resulting in the entire electrical circuit being in a virtual connection state

If the electrical connection coupler is used for a long time in this virtual connection state, it is easy to cause the surrounding plastic parts to melt due to the high heat generated at the virtual connection position, which will lead to failure.
