[0002] With the rapid development of the new energy vehicle industry, the requirements for conductive connection materials are also increasing. Copper busbars, as an excellent conductive material, are widely used in the conductive connections of new energy vehicles.

[0003] The prior art patent document with publication number CN209472039U provides a new type of insulated copper busbar, in which a layer of insulating paint film is coated on the copper busbar body. The thickness of the insulating paint film is very thin, and basically does not occupy space size, and has good insulation performance. Therefore, it saves the internal space of the battery box and solves the insulation protection problem. At the same time, it also ensures that the withstand voltage of the new type of insulated copper busbar is greater than 4.5KV.

[0004] Although the above-mentioned prior art achieves insulation protection by coating a layer of insulating paint film, the distance of the copper busbar is fixed during use and its length cannot be adjusted according to actual needs, which limits its application scope to a certain extent and cannot meet people's needs. Therefore, we need a new type of copper busbar for new energy vehicles. Utility Model Content

[0009] Preferably, the second copper busbar body forms a fixing structure with the second connecting ear through a fixing bolt, and one end of the fixing bolt is threadedly passed through the second connecting ear and extends into the threaded hole for connection.

[0010] Preferably, the number of the fixing bolts is two, and the two fixing bolts are symmetrically arranged on the second connecting ear.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] When the utility model is in use, the length can be adjusted as needed by pulling the second copper bar body to move in the slide groove of the first copper bar body. After the length adjustment is completed, the first copper bar body and the second copper bar body are fixed by installing a nut on the screw rod, thereby enhancing stability.

[0020] Through the above technical solution, by pulling the second copper bar body 4 to move in the slide groove 3 of the first copper bar body 1, the length can be adjusted as needed. After the length adjustment is completed, the first copper bar body 1 and the second copper bar body 4 are fixed by installing the nut 6 on the screw 5, thereby enhancing the stability. When the second connecting ear 8 is facing downward, it needs to be facing upward in some scenarios. The direction can be easily changed by simple disassembly and re-fixing. There is no need to replace the entire copper bar or perform complicated operations. The structure is simple and easy to use.

[0021] Specifically, the first copper busbar body 1 forms a sliding structure with the second copper busbar body 4 through the slide groove 3, and the inner wall of the slide groove 3 fits with the outer wall of the second copper busbar body 4.

[0022] Through the above technical scheme, the connection effect between the first copper bar body 1 and the slide groove 3 and the second copper bar body 4 is strengthened, which facilitates the sliding of the second copper bar body 4 in the slide groove 3.
