Comprising a plurality of battery cells, part of fault battery cells exist in the plurality of battery cells, the fault battery cells are disconnected and conductively connected between two normal battery cells and / or between the normal battery cells and an output end point of the battery pack, and the two normal battery cells and / or the normal battery cells and the output end point are conductively connected through connecting pieces. According to the utility model, the conductive connecting piece is used for replacing the conductive connection part of the faulted battery cell, so that the battery pack or the battery pack with the faulted battery cell can still be used, and the situation that the whole battery pack or the whole battery pack cannot be used due to the fault of part of the battery cells, and the whole battery pack or the battery pack needs to be replaced is avoided; resource waste is further avoided, and economic loss is reduced.

The utility model relates to an electroplating process glass product fixing device which comprises a top plate, a hollow rod is installed on the lower surface of the top plate, a motor is installed on the upper surface of the top plate, the end of an output shaft of the motor penetrates into the hollow rod and is connected with a threaded rod with a pair of reverse threads, and nuts are installed on the two reverse threads of the threaded rod. Four communicating grooves are formed in the outer surface of the hollow rod in a coaxial array mode, four arc-shaped clamping plates are arranged on the outer side of the hollow rod in a coaxial array mode, and the arc-shaped clamping plates and the nuts are connected through two connecting mechanisms. A motor drives a threaded rod to rotate, due to the arrangement of reverse threads, two nuts can be close to or away from each other, and then the purpose of driving four arc-shaped clamping plates to stretch out and draw back at the same time is achieved through the connecting effect of a connecting mechanism, so that glass cups with different diameters can be fixed, and the universality is improved; and when glass cups with different specifications are electroplated, the clamp does not need to be replaced, so that the operation complexity is reduced, and the production efficiency is improved.
