The utility model discloses a novel ultrathin folding charging head structure comprising a housing, and a PCBA board is fixedly installed in the housing. The number of the elastic sheets is two, and the elastic sheets are respectively installed on the PCBA board; the AC electric insertion piece is fixedly installed on a rotating shaft, rotating buckles are arranged on the two sides of the rotating shaft respectively, and the AC electric insertion piece is in conductive contact with the elastic piece; the mounting seat is arranged corresponding to each AC electric insertion piece, a rotating shaft mounting position is arranged on one surface of the mounting seat, an insertion piece groove is formed in the other surface of the mounting seat, one end of each AC electric insertion piece is rotationally mounted in the insertion piece groove, and the other end of each AC electric insertion piece extends into the rotating shaft mounting position. According to the utility model, a buckling fixing mode of the AC electric plug piece and the rotating shaft is adopted, and the use of a pressing plate and a screw in a traditional folding plug pin structure is avoided, so that the stacking thickness of the assembly is reduced, and the whole charging head is lighter and thinner.
