Embodiment Construction

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

[0020] Such as 1, figure 2 , image 3 As shown, a connection assembly between a battery tab and a cover plate includes a holder 6 , a holder 5 and a tab set 9 . A circular through hole is opened on the cover plate of the cage 6, and the holder 5 is an inverted T-shaped structure, and the holder 5 passes through the circular through hole on the cover plate of the cage 6, the two are interference fit, firmly connected together. Preferably, the holding member 5 is a rivet. The retainer 6 is equipped with a pressing sheet 8 for winding and squeezing the tab group 9, one end of the pressing sheet 8 is a shaft-shaped structure, and the other end is a rectangular structure; one end of the retainer 6 is opened for The circular through hole matched with the ...

Abstract

The invention provides a connecting assembly for battery lugs and a cover plate, and relates to the technical field of batteries. The connecting assembly comprises a retainer, a holder and a lug group, wherein the retainer is fixedly connected with the holder; and a pressing piece for winding and extruding the lug group is assembled on the retainer. The pressing piece is arranged on the retainer of the connecting assembly; the lug group is wound on the pressing piece and extruded between the pressing piece and the holder; and non-welding connection of the lugs and the cover plate is achieved, so that the current throughput is increased; the lugs which are not subjected to welding treatment can be recycled; the production cost is reduced; and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of batteries, and more specifically relates to a connection assembly between a battery tab and a cover plate. Background technique [0002] The currently used power battery generally includes a casing, a cover assembly, a battery cell, positive and negative tabs, and positive and negative electrodes. Countless charging and discharging of the battery core is achieved through effective communication of rivets on the cover plate, independent pole pieces, and tabs on the winding core. The connection between the pole piece and the rivet, and the connection between the pole piece and the tab are all completed by welding. . However, when the effective width and thickness between the pole piece, 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 cause overheating of the tab. In terms of p...
