The working process of the invention is as follows:
as shown in fig. 4, when the socket is not plugged with the plug, the socket connected to the device needs to perform short-circuit protection on static electricity and induced current on the electrical device of the device. The grounding contact 2.4 presses the contact bosses 2.11 of the two communication jacks 2.1 under the elastic force of the socket pressure spring 2.5, and the two communication jacks 2.1 are electrically connected with the grounding contact 2.4.

As shown in fig. 5, when the socket is plugged into the plug, the plug top post 7.2 on the plug is firstly in contact with the insulating top post 2.3, and since the coefficient of stiffness of the plug pressure spring 7.3 is greater than the coefficient of stiffness of the socket pressure spring 2.5, the plug top post 7.2 firstly pushes the ground contact 2.4 to move towards the compression direction of the socket pressure spring 2.5 through the insulating top post 2.3, the two communication jacks 2.1 are not electrically connected, and the short-circuit state is relieved. At this time, the detection pin 7.22 on the plug top post 7.2 is not inserted into the detection jack 7.4, and the detection mechanism shows that the short-circuit structure is not disconnected. After the socket pressure spring 2.5 is continuously inserted for a certain distance and is compressed to a certain amount, the elastic force is larger than the plug pressure spring 7.3, the plug pressure spring 7.3 is also gradually compressed, the detection contact pin 7.22 is inserted into the detection jack 7.4 along with the compression of the plug pressure spring 7.3, so that the grounding terminal 12 connected with the public grounding end forms a grounding path through the grounding plate 6, the plug pressure spring 7.3, the plug top post 7.2 and the detection jack 7.4, and because the connecting wire end of the detection jack 7.4 is connected with the detection end of the short-circuit detection device through the connecting wire, the short-circuit detection device can judge that the self-short-circuit link is completely disconnected, the communication jack 2.1 is electrically connected with the public grounding end, and the communication jack 2.1 can be inserted into the corresponding communication contact pin 7.1 for communication.
