Problems solved by technology

[0002] The battery takes a square battery as an example. The square battery mainly includes a cover assembly, a connecting sheet and a battery cell. The current common structure of the cover 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. Most of the parts are stamped and formed by dies, which virtually increases the cost of the dies.
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 Membrane process, two welding processes also increase the tediousness of the production process

Abstract

The invention discloses a connecting piece, a cover plate assembly, and a battery. The connecting piece comprises a body part, and at least one pole part arranged at one end of the body part, whereinthe other end of the body part serves as a connecting part connected with a tab of the battery, and the pole part is protruded out of the body part to serve as a pole of the battery. The connecting piece, the cover plate assembly and the battery provided by the invention have the advantages that the cover plate assembly can be connected with a battery core through the body part of the connecting piece; and the pole part can be used as the pole, so that additional poles need not be arranged on the cover plate assembly, the number of parts in the cover plate assembly can be decreased, and the corresponding mold cost can be reduced.

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...
