Technical Problem
因此，在汇流排组件与多个单体电池焊接过程中，除了焊接位置外，其他位置的汇流排容易与对应的单体电池的极柱接触导电，使得汇流排的通电顺序与预设顺序不同，进而导致电性元件受到不均衡的电压，出现电阻烧蚀的可能性大大增加
Benefits of technology
[0010]本实用新型通过将汇流排组件的多个汇流排分别与电性元件电性连接，有利于提高汇流排组件的集成度，使得后续汇流排组件和电池单体的连接更加便捷。同时，汇流排组件还设置有隔离件，隔离件上还设置有与极柱对应连接的安装孔，且汇流排在隔离件上的投影至少部分位于安装孔内，便于后续将该部分汇流排与极柱进行焊接。值得说明的是，隔离件还设置有支撑部，且支撑部具有初始状态和形变状态，置于初始状态时，用于将汇流排和极柱分开，可以有效地避免二者接触导通；当支撑部受力发生形变至形变状态时，汇流排能与极柱抵接，以便于焊接操作。另外，支撑部的弹性变形量过大会占用过多空间；过小则无法保证置于初始状态时汇流排和极柱之间有效的分隔，因此，支撑部的弹性变形量A设置为0.8mm-2mm。
