As shown in FIG. 3 , in this embodiment, the connecting terminal 12 is a conductive rod and is located at the center of the power socket 11 .

As shown in FIGS. 2 and 3 , the power plug 20 includes an insulator 21 , a conductive joint 22 and a fixing ring 23 . Wherein the conductive joint 22 is connected to the insulator 21 . The fixing ring 23 covers one end of the conductive connector 22 close to the insulator 21 , and the fixing ring 23 is provided with an external thread section 24 corresponding to the internal thread section 13 . In one embodiment, the conductive joint 22 can be made of a conductive material, for example, the conductive joint 22 can be a metal sheet, a metal rod or a metal block and has the function of conducting electricity. The insulating member 21 can be a casing made of insulating material (such as plastic or rubber). Wherein, the conductive connector 22 may have a plug-in end 222 , and the insulator 21 is sheathed outside the end of the conductive connector 22 opposite to the plug-in end 222 , so that the conductive connector 22 can be exposed from the insulator 21 . The fixed ring 23 is in the form of a collar and its diameter is smaller than that of the insulator 21. The fixed ring 23 is sleeved and fixed on the outside of the end of the conductive joint 22 relative to the insertion end 222 and adjacent to the insulator 21. That is to say, the fixed ring 23 is only It is sleeved outside the partial surface of the conductive joint 22 .

Thereby, as shown in FIG. 4 , during assembly, the user can first insert the plug-in end 222 of the conductive joint 22 of the power plug 20 into the power socket 11. Here, the conductive joint 22 is inserted into the power supply along the X-axis direction. slot 11, when the external thread section 24 of the fixing ring 23 contacts the internal thread section 13 of the power socket 11, the power plug 20 can be rotated so that the external thread section 24 is screwed on the internal thread section 13, so that the power plug 20 can Completely enter the power socket 11 (as shown in FIG. 3 ), and make the conductive joint 22 contact the connecting terminal 12 for power transmission.
