Battery pack signal sampling sheet

The invention discloses a battery pack signal sampling sheet which is used for connecting battery packs with PCBs, so as to enable the PCBs to collect coherent signals of the battery packs; each battery pack comprises a fixture provided with battery mounting holes, and single batteries arranged in the battery mounting holes in an inserting manner; each PCB comprises a board body, a signal acquisition line arranged on the board body and a welding insert hole formed in the board body; each sampling sheet comprises a battery connecting part and a PCB connecting part; the battery connecting parts are arranged in the battery mounting holes and are connected with the single batteries in the battery mounting holes; the PCB connecting parts extend out of the battery mounting holes and are positioned at the outer edges of the fixtures; welding bulges are arranged on the PCB connecting parts; the welding bulges extend into the welding insert holes and are fixed with the welding insert holes in a welding manner; the welding bulges are electrically connected with the signal acquisition lines on the PCBs. According to the battery pack signal sampling sheet, provided by the invention, the structure is simple, the assembly is convenient, the connecting strength between the PCBs and the battery packs can be ensured while the soldering amount is greatly reduced, and the PCBs can be assembled on the battery packs rapidly and stably.
