[0030] When the temperature of the connection between the plug connector 102 and the battery cell 100 increases, the temperature of the plug connector 102 will increase, and the temperature of the plug connector 102 can be transferred to the copper ring 201, and the copper ring 201 will transfer the heat to the heat-conducting ring 202, and the heat-conducting ring 202 will transfer the heat to multiple groups of fins, thereby increasing the contact area between heat and air, thereby improving the heat dissipation performance of the connection between the two groups of battery cells 100. The provision of silicone grease can fill the gap between the outer wall of the plug connector 102 and the inner wall of the copper ring 201, and the silicone grease has good thermal conductivity, which further improves the thermal conductivity of the copper ring 201.

[0031] Please refer to Figure 1-4 The right end of the heat-conducting ring 202 is provided with a docking mechanism 300, and the docking mechanism 300 includes a mounting seat 301. The right end of the heat-conducting ring 202 is fixedly connected with the mounting seat 301, and the right end of the protective cover 101 is fixedly connected with a fixing head 302, and the outer wall of the battery cell 100 is fixedly connected with the inner wall of the fixing head 302, and the outer wall of the fixing head 302 is slidably connected with the inner wall of the mounting seat 301.
