Then, through the insertion hole and the snap-fit ​​groove, the rotating rod 7 and the rotating block 8 can be inserted into one side of the connecting plate 6. Then, the rotating rod 7 is rotated 90 degrees so that it is intersected with the snap-fit ​​groove. The intersecting of the rotating rod 7 can prevent the connecting plate 6 and the mounting plate 5 from separating.

[0039] Working principle: In actual use, the male connector 1 is connected to the end to be charged, and then the female connector 2 is connected to the power transmission equipment. Then, the male connector 1 and the female connector 2 are mated. After that, the two second power terminals 11 and the multiple second signal terminals are respectively plugged into the two first power terminals 9 and the multiple first signal terminals 10. After the current docking is completed, the current is transmitted through the female connector 2 to the male connector 1 and supplements the electrical appliance that needs to be charged. After the male connector 1 and the female connector 2 are connected, the docking rod 13 is inserted into the positioning groove 15.
