The investment cost of charging piles throughout the entire usage process is also a major issue for major charging pile manufacturers in their deployment. The cost of the charging gun on the charging pile is also an important procurement indicator for charging gun suppliers. As a manufacturer of charging guns, it is necessary to meet increasingly stringent standards while minimizing the cost of charging guns. This requires controlling product costs from the design stage. This can be achieved by optimizing the design scheme, simplifying the internal structure of the charging gun, making the component design more reasonable, improving the production process, reducing the difficulty and complexity of component production, reducing resource consumption and time costs in the production process, thereby effectively reducing the production cost of charging guns and enhancing the product's competitiveness in the market.

[0003] Existing charging gun head assembly fixing structures typically require the placement of embedded nuts in the gun head, which involves complex injection molding processes and high injection molding costs. Furthermore, due to the studs on the inside of the handle, the internal structure cannot form a complete circle and can only use end face sealing, which results in a low level of sealing.
