[0015] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1~Figure 2 The new energy vehicle charging gun shown includes a lower shell 1 and an upper shell 3 that are relatively snap-connected together. The cavity formed between the lower shell 1 and the upper shell 3 accommodates the carrier 2. The front end of the lower shell 1 is integrally provided with a charging head 11, and the top of the upper shell 3 is provided with a pressing portion. Glue is poured around the carrier 2 and between the inner walls of the lower shell 1 and the upper shell 3. A plurality of terminals 23 are provided at the front end of the carrier 2, and the plurality of terminals 23 are embedded in the through holes of the charging head 11. The rear end of the carrier 2 is connected to a cable 5, and a net tail 51 is provided on the rear end through holes of the lower shell 1 and the upper shell 3, and the cable 5 extends from the through hole of the net tail 51.

[0017] Specifically, the charging head 11 and the lower shell 1 are made into one piece, which simplifies the structure and reduces the assembly time. The upper shell 3 and the lower shell 1 are assembled directly by clamping and fixing without screws, which not only reduces the number of parts, but also reduces the assembly time and improves the production and assembly efficiency. The gaps on the carrier 2 and the surroundings are filled with glue, filling the entire cavity gap between the lower shell 1 and the upper shell 3, which is waterproof and insulated, so that the protection level of the entire charging gun reaches IP67.
