In order to achieve the above object, the utility model provides an outer negative pole shell fragment of vehicle charger for adopt vehicle charger of interior negative pole shell fragment and outer negative pole shell fragment structure, including being circular-arc shell fragment body, the shell fragment body includes first contactable face and connects first bullet arm and the second bullet arm at first contactable face both ends, the one end that first bullet arm kept away from the first contactable face is connected with first contact site, the one end that the second bullet arm kept away from the first contactable face is connected with the second contact site, still be provided with the third bullet arm on the second contact site, be provided with the second contactable face on the third bullet arm; the first contact part and the second contact part are used for being abutted against a metal part of the negative pole of the automobile cigarette lighter socket.
Preferably, the first contact portion and the second contact portion are both arranged in a convex manner, and the convex direction faces the outside of the arc of the elastic sheet body.
Preferably, the radian of the elastic sheet body is larger than 270 degrees.
Preferably, the first elastic arm and the second elastic arm are symmetrically arranged at two ends of the first contactable surface, and the first elastic arm, the second elastic arm and the third elastic arm have the same structure.
Compared with the prior art, the beneficial effects of the utility model are that: the assembly bi-directional property of the inner negative electrode elastic sheet and the outer negative electrode elastic sheet in the assembly process is realized, the product defect caused by the assembly direction of the inner negative electrode elastic sheet and the outer negative electrode elastic sheet in the production and assembly process of the product is avoided, and the automatic production and assembly of the product are facilitated.
