[0080] Next, a TYPE-C fast charging female head is provided, which includes an insulating body 200, a female terminal set 100 arranged on the insulating body 200, and a shell 300 (usually made of metal material, which has covering and shielding effects) wrapped around the outer periphery of the insulating body 200.

The female terminal set 100 is the female terminal set 100 of any one of the preceding embodiments.
[0081] During production, the female terminal set 100 can be integrally injection molded and fixed in the insulating body 200, or the female terminal set 100 can be inserted and fixed in the insulating body 200. The left and right sides of the tongue 2001 of the insulating body 200 are designed with hook matching convex parts at the front end for matching the hooks of the male head. The hook matching convex parts can be integrally formed by the plastic part of the tongue 2001 itself, or metal parts can be embedded, and the hook matching convex parts are designed on the metal parts. In this way, the hook matching convex parts are exposed on the left and right sides of the tongue 2001 as hook matching convex parts, or the hook matching convex parts are embedded in the plastic hook matching convex parts on the left and right sides of the tongue 2001, which together form the hook matching convex parts.
[0082] In the embodiment, the TYPE-C fast charging female head further comprises a metal partition sheet 400 which is fixed in the insulating body 200 by injection molding together with the female head terminal group 100.
