[0014] 1. This type of liquid-cooled DC charging gun terminal removes the fixing bolt from inside the limit screw and the terminal base, thus eliminating the contact force between the fixing bolt and the terminal base. The rotating connecting shaft inside the U-shaped frame allows the rotating block fixed on the outer surface of the connecting shaft to rotate. As the rotating block rotates, the position of the receiving plate fixed on the left side of the rotating block changes synchronously. When the position of the receiving plate changes, the bottom of the fixing bolt fixed on the left side of the limit screw moves away from the surface of the terminal base. This effectively solves the problem of how to replace the terminal body, enabling convenient replacement after prolonged use, reducing maintenance costs, ensuring charging efficiency, and improving actual usage efficiency.
[0015] 2. This type of liquid-cooled DC charging gun terminal places the liquid cooling source inside the liquid flow guide column. Then, through the connection between the liquid flow guide column and the terminal base, the liquid cooling source enters the equipment to perform related heat dissipation. After the liquid cooling source is used, it can be recycled through another set of liquid flow guide columns. This solves the problem of how to dissipate heat inside the equipment, achieving a more efficient operation, ensuring effective heat dissipation, avoiding damage to the equipment due to excessive temperature, and reducing maintenance costs in practice.
