Description

一种可自动吸合脱离的直流电气对接装置A DC electrical docking device capable of automatic pull-in and detachment

技术领域technical field

本发明涉及一种电气对接装置，更特别地说，是指一种可自动吸合脱离的直流电气对接装置。The invention relates to an electrical docking device, more particularly, to a DC electrical docking device that can be automatically engaged and disengaged.

背景技术Background technique

可自动吸合脱离的直流电气对接装置是一种可以实现浮动对接的电气插头装置。当由于客观原因使对接头不能够完全对正、或者彼此无法接触时，对接触点可以通过磁铁相互吸合而导通电路；当相互分离时，触头可以彼此分开，切断电路。该装置可广泛应用于远程遥控对接、航空航天、野外救护、危险作业等领域。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.

传统的直流电气对接装置主要采用插接式，该类装置要求电气触点彼此充分接触，方可避免接触不良导致失效。但是在远程遥控对接、野外远程操作、危险作业等情况下，则有以下几点不足：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 by poor contact. However, in the case of remote control docking, remote operation in the field, dangerous operations, etc., there are the following shortcomings:

1)插接式装置需要在基本对正情况下实现插接，若客观限制无法基本对正，则无法完成对接。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.

2)对接头彼此插接后相互位置完全固定，而在某些应用场合，要求彼此位置具有一定程度的浮动和游移距离，插接形式的对接头将无法满足这些应用要求。2) After the butt joints are plugged into each other, the mutual positions are completely fixed, but in some applications, a certain degree of floating and wandering distance is required for each other's positions, and the plug-in butt joints will not be able to meet these application requirements.

本发明的一种可自动吸合脱离的直流电气对接装置的动作过程为：The action process of a DC electrical docking device capable of automatic pull-in and detachment of the present invention is as follows:

当浮动模块与固定模块彼此接近时，A浮动触点8向A固定触点14靠近，B浮动触点9向B固定触点15靠近，当A永磁铁10与C永磁铁12进入作用距离(一般可以为0～40毫米)后，磁铁S极10b与磁铁N极12a彼此吸合，B浮动触点9与B固定触点15紧密贴合，同时A复位弹簧6被拉长，处于松弛状态的A牵引导线5适度伸长，由A牵引导线5将A接线柱1的A出线端1a、A固定触点14的C出线端14b相互导通。B复位弹簧17也被拉长，处于松弛状态的B牵引导线18伸长，B接线柱2的B出线端2a、B固定触点15的D出线端15b相互导通。When the floating module and the fixed module approached each other, the A floating contact 8 approached the A fixed contact 14, and the B floating contact 9 approached the B fixed contact 15. When the A permanent magnet 10 and the C permanent magnet 12 entered the working distance ( Generally, it can be 0 to 40 mm), the S pole 10b of the magnet and the N pole 12a of the magnet are attracted to each other, the B floating contact 9 and the B fixed contact 15 are closely attached, and the A return spring 6 is stretched and is in a relaxed state The A pulling wire 5 is moderately elongated, and the A outlet end 1a of the A terminal 1 and the C outlet end 14b of the A fixed contact 14 are connected to each other by the A pulling wire 5 . The B back-moving spring 17 is also elongated, and the B traction wire 18 in a relaxed state is elongated, and the B outlet end 2a of the B terminal 2 and the D outlet end 15b of the B fixed contact 15 are mutually conducted.

当A浮动触点8与B固定触点15接近，或者B浮动触点9与C固定触点14接近时，由于相对的磁铁极性相同，则彼此排斥，以避免反接直流电路。When the A floating contact 8 is close to the B fixed contact 15, or the B floating contact 9 is close to the C fixed contact 14, since the opposite magnets have the same polarity, they repel each other to avoid reverse connection of the DC circuit.

当浮动模块与固定模块位置发生游移或错动时，A复位弹簧6与A牵引导线5、B复位弹簧17与B牵引导线18会随之弯曲或伸缩，保持直流电路的线路导通。When the position of the floating module and the fixed module shifts or shifts, the A return spring 6 and the A traction wire 5, the B return spring 17 and the B traction wire 18 will bend or stretch accordingly to keep the DC circuit conducting.

当浮动模块与固定模块彼此逐渐远离时，A复位弹簧6和B复位弹簧17逐渐拉长，松弛的A牵引导线5和B牵引导线18绷紧，当A牵引导线5和B牵引导线18的拉力超过永磁铁彼此吸力时，A浮动触点8向A固定触点14脱离，B浮动触点9向B固定触点15脱离，同时A复位弹簧6和B复位弹簧17将A浮动触点8、B浮动触点9拉回至浮动对接头7的A定位锥面7c、B定位锥面7d，直流电路的线路即被切断。When the floating module and the fixed module are gradually moving away from each other, the A return spring 6 and the B return spring 17 are gradually elongated, and the loose A traction wire 5 and B traction wire 18 are tightened. When the mutual attraction force of the permanent magnets is exceeded, the A floating contact 8 will disengage from the A fixed contact 14, and the B floating contact 9 will disengage from the B fixed contact 15. At the same time, the A return spring 6 and the B return spring 17 will move the A floating contact 8, The B floating contact 9 is pulled back to the A positioning cone surface 7c and the B positioning cone surface 7d of the floating butt joint 7, and the line of the DC circuit is cut off.
