DC electrical docking device capable of automatically actuating and disconnecting

Abstract

The invention discloses a DC electrical docking device capable of automatically pulling-in and disconnecting, comprising a floating module and a fixed module, wherein, the floating module consists ofa wiring post A, a wiring post B, a plug A, a plug B, a traction conductor A, a traction conductor B, a return spring A, a return spring B, a floating butt joint, a floating contact point A, a floating contact point B, a permanent magnet A and a permanent magnet B; and the fixed module consists of a permanent magnet C, a permanent magnet D, a fixed contact point A, a fixed contact point B and a fixed butt joint. The return spring A and the traction conductor A are communicated with the floating contact point A and the wiring post A; and the return spring B and the traction conductor B are communicated with the floating contact point B and the wiring post B. When the floating module is close to the fixed module, the permanent magnet A is connected with the permanent magnet C in an actuatingmanner, and the floating contact point B is connected with the permanent magnet D in an actuating manner; and when the floating module is separated from the fixed module, the two traction conductorspull away the two floating contact points to disconnect circuits with each other. The device can keep conduction in the case of vacillation and dislocation of the two plug bodies, and is particularlyapplicable to the fields of remote circuit conduction, field remote control operation and the like.

Description

technical field [0001] The invention relates to an electrical docking device, more particularly, to a DC electrical docking device that can be automatically engaged and disengaged. Background technique [0002] The DC electrical docking device that can automatically pull in and disengage is an electrical plug device that can realize floating docking. When the butt joints cannot be completely aligned or cannot be in contact with each other due to objective reasons, the contact points can be attracted to each other by magnets to conduct the circuit; when they are separated from each other, the contacts can be separated from each other to cut off the circuit. The device can be widely used in remote control docking, aerospace, field rescue, dangerous operations and other fields. [0003] The traditional DC electrical docking device mainly adopts plug-in type, and this type of device requires the electrical contacts to be in full contact with each other to avoid failure caused b...

AI Technical Summary

Problems solved by technology

[0004] 1) The plug-in device needs to be plugged in the basic alignment. If the objective limit cannot be basically aligned, the docking cannot be completed

[0005] 2) After the butt joints are plugged into each other, the mutual positions are completely fixed, and in some applications, a certain degree of floating and wandering distance is required for each other's positions, and the butt joints in the plug-in form will not be able to meet these application requirements
