A working principle of the anti-electric shock type power supply plugging system is that when a plug is inserted into a socket cavity of a socket, guide rails on two sides of a socket body are simultaneously inserted into guide grooves, and when the plug continues to move downwards, the guide rails on the two sides of the socket body press spring pieces on the sides where the guide rails are located, so that the spring pieces move outwards, and as a result, a hook is separated from the bottom of a movable connecting block; when power transmission work is not needed, under the action of a reset spring, the movable connecting block moves upwards along with the plug, and when the movable connecting block moves to the position where the bottom is higher than the hook and the plug is pulled out at the moment, under the action of the elastic force of the reset spring, the movable connecting block moves upwards along with the plug. The hook extends out to support the bottom of the movable connecting block, the movable connecting block is limited to be incapable of continuing to move downwards, the lower portion of the conductive column does not make contact with the conductive base, and the conductive device has the advantages of being safe and reliable.
一种防触电型电源接插系统,工作原理是:当插头插入插座的座腔,插座体两侧的导轨同时插入导向槽内,当插头继续向下时候,插座体两侧的导轨压迫所在边的弹簧片,使弹簧片向外侧移动,结果是弯钩脱离活动连接块的底部,解除活动连接块向下运动的限制,并与导电座接通,于是正常的输电工作,当不需要输电工作,在复位弹簧的作用下,活动连接块随插头一起向上运动,当运动到底部高于弯钩的位置时,并在此时插头被拔出时候,复位弹簧在自身弹力作用下,弯钩伸出托住在活动连接块的底部,限制活动连接块无法继续向下运动,并且导电柱的下方与导电座之间不接触,本发明具有具有安全可靠的优点。
