The adapter includes a first connecting portion, a fuse portion, and a second connecting portion, and a ratio of the width of the fuse portion in a width direction of the adapter to the width of the first connecting portion and a ratio of the width of the fuse portion in the width direction of the adapter to the width of the second connecting portion each are in a range from 1/6 to 4/5. The first connecting portion is provided with first corners at an end of the first connecting portion close to the second connecting portion, and the second connecting portion is provided with second corners at an end of the second connecting portion close to the first connecting portion. The insulator is provided with a first protective portion, a second protective portion and a third protective portion in a length direction of the adapter. The first protective portion covers the first corners, the second protective portion covers the second corners, the third protective portion covers a first surface of the fuse portion of the adapter, and a second surface of the fuse portion is at least partially exposed from the insulator. According to the present disclosure, an electrode assembly can be prevented from being cut by the first corners and the second corners by covering the first corners and the second corners with the insulator, thereby effectively protecting the electrode assembly.
