Embodiment Construction

[0019] An integrated connection structure for the connection between battery cells, including a battery composed of at least two cells in series, each cell consists of a plurality of positive and negative plates stacked alternately, and a separator separating the positive and negative plates The tabs of the positive and negative plates of the monomer are respectively connected to two bus bars. Each cell is separately installed in the cell in the battery case, and the negative electrode bus bar on the previous cell is connected to the positive electrode bus bar on the next cell through a connecting piece. In the present invention, the two interconnected bus bars The row and the connector connecting the two busbars are integrally cast and formed, and the three are connected in an integrated structure. Through this one-piece connection structure, the connection between the monomers is completed at the same time when the two busbars are respectively welded to the pole plates of th...

Abstract

The invention provides an integrated connection structure and equipment mould used for connecting with single battery which includes a battery constituted by at least two singles in series, front single cathode omnibus bar connects with next single anode omnibus bar through connection part. The connected two omnibus bars and connection part are integrated casting formed. The equipment mould includes as follows: a moulding plate with at least one group connection groove, each group connection groove is composed of two grooves, a moulding hole is set on confluence position of two grooves; an insertable mould hole plug-in. When the equipment mould is injected with lead liquid, two grooves of the equipment mould form an omnibus bas respectively, the connection part connected two omnibus bars into a whole is formed in the mould hole. The integrated connection structure can realize production of a plurality single battery at one time and avoid operation sequence of connecting with single battery.

Description

technical field [0001] The invention relates to a battery structure, in particular to a connector structure for connecting cells in a multi-cell battery and a tooling mold for making the connector. Background technique [0002] Lead-acid batteries are one of the most widely used battery types in the world. At present, China is the world's largest producer of lead-acid batteries. With the purchase and manufacture of lead-acid batteries from western countries gradually shifting to China, China's lead The manufacturing technology of acid batteries has also been continuously improved. [0003] In a multi-cell battery, the cells need to be connected in series to obtain a higher voltage. In the existing battery composed of multiple cells connected in series, generally a welding post is set up on the negative electrode bus bar on the previous cell, and a welding post is also set up on the positive electrode bus bar on the next cell. When the cells are connected to each other, The...
