The first connecting piece 11 is manufactured by a stamping and rolling process, and/or the second connecting piece 12 is manufactured by a cold heading forming process. The first connecting piece 11 comprises a plurality of groups of elastic sheet assemblies which are arranged at intervals along the circumferential direction of the first connecting piece and extend along the axial direction of the first connecting piece, and each group of elastic sheet assemblies at least comprises a first elastic sheet 13 and a second elastic sheet 14 which are arranged at intervals. The length of the first elastic piece 13 along the axial direction of the first connecting piece 11 is greater than the length of the second elastic piece 14 along the axial direction of the first connecting piece 11. The first spring 13 is a long spring, and the second spring 14 is a short spring. The first connecting piece 11 has at least 3 groups of spring plate assemblies thereon.

That is, the support beam 15 protrudes inward to form the first bead 22. A first opening 23 is formed on a side of the first connecting member 11 facing away from the second connecting member 12, and a plurality of second ribs 24 are formed on an inner wall of the first opening 23 in an inward protruding manner. Based on the arrangement of the first protruding rib 22 and the second protruding rib 24, the male terminal can be corrected in the process of inserting the male terminal, the angle of oblique insertion and extraction is reduced, the elastic sheet is protected, and the elastic sheet is prevented from being damaged.

Referring to fig. 4 and 5, in the present embodiment, a guiding protrusion 25 is provided on the outer side of the housing on the side facing away from the second connector 12 of the first connector 11, and the guiding protrusion 25 is used for guiding and positioning the current-carrying terminal during the process of inserting the terminal into the housing of the charging gun, that is, the terminal is inserted into the housing of the charging gun in a certain direction and is kept not to rotate in the housing of the charging gun.

Referring to fig. 3, in the present embodiment, the second connecting member 12 has a second end 19, and the diameter of the first end 16 is smaller than that of the second end 19, so that the first end 16 of the first connecting member 11 is accommodated in the second end 19 of the second connecting member 12.

With continued reference to fig. 3, the second connector 12 has a third end 20 opposite the second end 19. The third end 20 may be a press-fit structure, a welded structure, or a screw-fit structure, which is not limited in the present utility model.
