Abstract

本发明公开了一种电池组导电条结构,包括铝导电条、镍片和螺栓,所述铝导电条的输出极端开有螺纹孔,在镍片上设有圆形通孔,两个镍片分别热压焊接在铝导电条输出极端的上下两端面上,且镍片上的圆形通孔和铝导电条上的螺纹孔相贯通,螺栓穿设在圆形通孔和螺纹孔内。本发明的铝导电条结构可靠,相当于铝镀镍,镀镍的表面很容易损坏,但是热压焊接镍片的结构强度比铝镀镍高,通过热压镍片后铝导电条与联接电池组的铜导电线接触电阻低,而且避免铜铝直接接触的电化学腐蚀,在满足性能要求的情况下,相对现有需要铜铝转接的方式,结构简单,成本降低。

Description

一种电池组导电条结构
技术领域:
本发明涉及一种电池组导电条结构。
背景技术:
现有方形电芯组成的电动汽电池组的导电条为铝材质,而铝不能直接与电池组相互联接的铜导电线进行连接,否则不仅接触电阻大,而且会产生电化学腐蚀。现有技术通常采取铝导电条超声波焊接铜电极后,再通过铜电极与联接电池组的铜导电线进行连接,成本高,工艺复杂。
发明内容:
本发明是为了解决铜铝不能直接接触而采取的一种电池组导电条结构。
本发明所采用的技术方案有:一种电池组导电条结构,包括铝导电条、镍片和螺栓,所述铝导电条的输出极端开有螺纹孔,在镍片上设有圆形通孔,两个镍片分别热压焊接在铝导电条输出极端的上下两端面上,且镍片上的圆形通孔和铝导电条上的螺纹孔相贯通,螺栓穿设在圆形通孔和螺纹孔内。
进一步地,所述镍片厚度≥0.1mm。
进一步地,所述铝导电条的输出极端设有凹槽部,镍片热压焊接在该凹槽部内。
进一步地,所述镍片的电芯方向为圆弧边结构。
本发明具有如下有益效果:本发明的铝导电条结构可靠,相当于铝镀镍,镀镍的表面很容易损坏,但是热压焊接镍片的结构强度比铝镀镍高,通过热压镍片后铝导电条与联接电池组的铜导电线接触电阻低,而且避免铜铝直接接触的电化学腐蚀,在满足性能要求的情况下,相对现有需要铜铝转接的方式,结构简单,成本降低。
附图说明:
图1为本发明结构图。
图2为本发明爆炸图。
具体实施方式:
下面结合附图对本发明作进一步的说明。
如图1和图2所示,本发明公开一种电池组导电条结构,包括铝导电条1、镍片2和螺栓3,铝导电条1的输出极端开有螺纹孔11,在镍片2上设有圆形通孔21,两个镍片2分别热压焊接在铝导电条1输出极端的上下两端面上,且镍片2上的圆形通孔21和铝导电条1上的螺纹孔11相贯通,螺栓3穿设在圆形通孔21和螺纹孔11内。铝导电条1的输出极端通过螺栓3与联接电池组的铜连接线相连。
镍片2的厚度≥0.1mm。在铝导电条1的输出极端设有凹槽部12,镍片2热压焊接在该凹槽部12内。
本发明中镍片2的电芯方向为圆弧边结构22,为便于配合安装,凹槽部12的左端侧壁为圆弧边。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下还可以作出若干改进,这些改进也应视为本发明的保护范围。
