Abstract
Description
technical field
[0001] The invention relates to a battery structure, in particular to a connecting piece, a cover plate assembly and a battery. Background technique
[0002] The battery takes a square battery as an example. The square battery mainly includes a cover plate assembly, a connecting sheet and a battery cell. The current common structure of the cover plate assembly is as follows: figure 1 As shown, this type of cover plate assembly includes multiple parts such as pole d, pressure plate c, stop frame a, and base plate b, among which most of the parts are formed by stamping with a mold, which virtually increases the cost of the mold. Moreover, in the battery assembly process, it is necessary to ultrasonically weld the tabs of the battery cell to the connecting piece, and then laser weld the connecting piece to the pole d to realize the electrical connection between the cover plate assembly and the battery cell, and then pack The membrane process and the two welding...
