Rotating electric connection device and plug, socket thereof as well as electric connection method

Abstract

The invention relates to a rotary electrical connection device, as well as the plug, the socket and the electrical connection method thereof. The electrical connection device comprises at least a plug and at least a socket, wherein the plug is provided with a plugging bolt, and at least two first metal contacts used for conduction and connection are respectively arranged on the plugging bolt; the socket is provided with a plugging bolt hole adapted to the plugging and the pulling of the plugging bolt, an insertion guide slot and a pull guide slot which are respectively arranged on the hole wall of the plugging bolt hole, and at least two second metal contacts used for the conduction and the connection; the insertion guide slot and the pull guide slot deviate by a first reservation angle along the aperture direction; the insertion guide slot corresponds to an insertion position, and the pull guide slot corresponds to a conduction position; the plugging bolt is inserted along the insertion guide slot in the insertion position, and rotated to the conduction position from the insertion position at the first reservation angle, so that the first metal contacts are in frictional contact with the second metal contacts; the plugging bolt is directly pulled out of the plugging bolt hole along the pull guide slot in the conduction position to ensure that the first metal contacts and the second metal contacts are separated and powered off.

Description

technical field [0001] The invention relates to a rotary electrical connection device and its plug, socket and electrical connection method, in particular to a rotary electrical connection device and its socket which can be directly pulled out and cut off by rotation, and is not only suitable for electrical plugs and sockets. Common sockets, wiring boards, cassette sockets, special movable sockets and other weak current electrical devices are especially suitable for strong electrical devices. Background technique [0002] At present, the common electrical connection methods and devices are all direct plug-in type, which connects when plugged in, and disconnects when pulled out. Although this traditional electrical connection method and device is relatively simple to use, it relies on the resilience and conductivity of the metal contacts to complete the electrical connection. Such metal contacts must have the dual functions of conduction and clamping at the same time, which ...
