Storage battery

一种蓄电池

Abstract

本实用新型公开了一种蓄电池,包括电池壳、汇流排、极群、极柱和封装,电池壳具有多个单格的腔体,极群对应放置在每个腔体内,极群通过汇流排与极柱连接,电池壳内设置有电池芯,电池芯边沿环绕设置有框状的盖体,盖体包括面盖、底盖和两条侧盖,侧盖为弹性塑料所制成,侧盖的两侧边沿均设有密封槽,面盖中设置有保护电路基片,保护电路基片中设置有可与电池芯正、负极连接并作为导出端子的金属片,该实用新型通过框状的盖体封装电池芯,改进了蓄电池封装结构,可以防止注塑封装对电池芯的损坏,并能降低蓄电池生产成本。
The utility model discloses a storage battery. The storage battery comprises a battery case, a busbar, pole groups, post terminals and a package, wherein the battery case is provided with a plurality of simple lattice cavities; the pole groups are correspondingly placed in the cavities and are connected with the post terminals by the busbar; a battery cell is arranged in the battery case; the edge of the battery cell is surrounded by a frame-shaped cover body; the cover body comprises a surface cover, a bottom cover and two side covers; the side covers are made from elastic plastics; sealing grooves are formed in the edges at the two sides of each side cover; a protective circuit substrate is arranged in the surface cover; metal sheets which can be connected with an anode and cathode of the battery cell and serve as leading-out terminals are arranged in the protective circuit substrate. The storage battery has the beneficial effects that by packaging the battery cell by the frame-shaped cover body, the package structure of the storage battery is improved, damages of injection molded packages to the battery cell can be prevented and the production cost of the storage battery can be reduced.
