[0026] Based on the above scheme, the device avoids the situation where the protective plate 13 and the connecting member 14 occupy the thickness of the head of the battery cell 11 by setting the protective plate 13 in the gap between the two battery cells 11, that is, the installation space 12, and setting the connecting member 14 to a shape extending along the surface of the shell 111, thereby ensuring the capacity of the battery cell 11, and the device only needs to connect the protective plate 13 and the pole ear 112 through the connecting member 14 to complete the assembly, and the whole assembly process is very simple.

[0027] like Figure 1 As shown, in order to facilitate the connection between the pole ear 112 and the connecting portion 131, the protection plate 13 includes two connecting portions 131 approximately spaced apart along the second direction Y, the battery cell 11 includes two pole ears 112, one of which is a positive pole ear 113 and the other is a negative pole ear 114, the positive pole ear 113 and the negative pole ear 114 are approximately spaced apart along the first direction X on one side of the shell 111 in the second direction Y; the positive pole ear 113 and the negative pole ear 114 located in the same battery cell 11 are respectively connected to different connecting portions 131 through the connecting member 14; the positive pole ear 113 and the negative pole ear 114 located in different battery cells 11 are connected to the same connecting portion 131.
