It is worth noting that when it is inserted forward, the detection terminal 24b of the receptacle connector 2 is not connected to the plug connector 1. any terminal contact; when reversely inserted, the detection terminal 24b is in contact with the detection terminal 13 of the plug connector 1 to realize electrical properties, and at this time the detection terminal 24a is not in contact with any terminal of the plug connector 1; when the plug When the number of detection terminals of the connector 1 corresponds to the detection terminals of the socket connector 2, when the two are plugged together, all the detection terminals are in contact with each other to achieve electrical connection, and which detection terminal to choose , those skilled in the art can make a choice according to the needs of the actual situation, under the premise of the technical solution of the present invention, without any creative work, so it will not be described in detail here; vice versa, combined with the above description of forward insertion It can be seen that when the plug connector 1 is inserted into the receptacle connector 2 in reverse, since the terminals of the plug connector 1 and the receptacle connector 2 are in a forward and reverse insertion structure, and the symmetry center O of the two overlaps after insertion, the plug When the connector 1 is reversely inserted into the receptacle connector 2 , the plug connector 1 and the receptacle connector 2 achieve the same effect as when they are inserted forwardly, so details will not be described here.

Continuing to show in Fig. 1-Fig. 11, in the above-mentioned embodiment, only the plug connector 1 has four power terminals 12 and one detection terminal 13, and the receptacle connector 2 has four power terminals 23 and two detection terminals. The terminal 24 is described as an example; of course, the present invention can also have the following specific embodiments: if the plug connector 1 is set to have four power terminals and two detection terminals, and the socket connector 2 is set to have four power terminals 23 and one detection terminal 24, or the plug connector 1 is set to have eight power terminals and two detection terminals, the receptacle connector 2 is set to have eight power terminals 23 and one detection terminal 24, or the plug connector 1 It is set to have eight power terminals and one detection terminal, and the receptacle connector 2 is set to have eight power terminals 23 and two detection terminals 24, etc., those skilled in the art according to the needs of the actual situation, in the present invention On the premise of the technical solution, the required number of power supply terminals and detection terminals can be selected without any creative work, so no more details are given here.

In addition, the working principles of the power terminals and detection terminals of the plug connector and the socket connector involved in the present invention are well known to those skilled in the art, and will not be described in detail here.

What is disclosed above is only a preferred embodiment of the present invention, and of course it cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the patent scope of the present invention still fall within the scope of the present invention.
