Embodiment Construction

[0019] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific drawings.

[0020] Such as 1, figure 2 , image 3 As shown, a connecting assembly of battery tabs and cover plate includes a holder 6, a holder 5 and a tab group 9. The cover plate of the holder 6 is provided with a circular through hole. The holder 5 has an inverted T-shaped structure. The holder 5 passes through the round through hole on the cover plate of the holder 6. Fixedly connected together. Preferably, the holding member 5 is a rivet. The holder 6 is equipped with a pressing piece 8 for winding and squeezing the tab assembly 9. One end of the pressing piece 8 is a shaft-shaped structure and the other end is a rectangular structure; one end of the holder 6 is opened for A circular through hole matched with the axial structure of the pressing plate 8 is prov...

Abstract

A connection assembly between a battery tab and a cover plate, relating to the technical field of batteries, comprising a holder, a holder and a tab group, the holder is fixedly connected to the holder, and the holder is equipped with Tabs for tabs. The holder of the connection assembly is equipped with a pressing piece, and the tab group is wound on the pressing piece and squeezed between the pressing piece and the holder, realizing the non-welding communication between the tab and the cover plate, thereby increasing the current of the battery Circulation; tabs that have not been welded can be recycled, which reduces production costs and improves production efficiency.

Description

Technical field [0001] The present invention relates to the technical field of batteries, and more specifically to a connection assembly of battery tabs and cover plates. Background technique [0002] The currently used power battery generally includes a casing, a cover plate assembly, a battery cell, a positive and negative electrode lug, and a positive and negative electrode sheet. The countless times of charging and discharging of the battery cell are realized by the effective connection of the rivets on the cover plate, the independent pole pieces, and the pole ears on the winding core. The connection between the pole piece and the rivet, and the connection between the pole piece and the pole lug are all completed by welding. . However, when the effective width and thickness between the pole piece and the rivet and the tab are constant, welding will reduce the effective area of ​​current flow, reduce the current flow, increase the temperature and resistance, and may also cau...
