Wherein, the conductor 1 of this embodiment includes folded portion 3 and fixed part 4, the one end and the fixed part 4 body coupling setting of folded portion 3, the other end of folded portion 3 with connection piece 2 electricity is connected, after conductor 1 is folded, folded portion 3 with fixed part 4 sets up perpendicularly.

Specifically, the present embodiment fixes the tabs 2 at the corresponding positions by folding, and also facilitates the connection with the external battery module in order to provide a certain distance between the adjacent tabs 2. The different lengths of the conductors 1 can be designed such that all the lugs 2 are located in the same horizontal line. Generally, in the structural design for detecting the battery module, the connecting sheet 2 is generally made of nickel sheets, and the nickel sheets can be designed to have different lengths according to different position requirements, for example, an FPC flexible printed circuit board is used, if the distance between the battery module and the connecting sheet 2 is longer, the connecting sheet 2 with the longer length is inevitably needed to be used, but in the embodiment, the position of the connecting sheet 2 is controlled by folding the conductor 1, in fig. 2, the farther the connecting position of the folding part 3 and the fixing part 4 is left, the farther the position of the connecting sheet 2 is up or down, so in the embodiment, the length of the connecting sheet 2 can be shorter, and the position of the connecting sheet 2 can be changed by changing the folding position of the conductor 1, so that the material of the connecting sheet 2 can be saved, and the cost can be further reduced.
