Technical Problem
[0002]动力电池接地线束是指连接电动汽车动力电池与车身金属底盘之间的专用导线、连接器、固定件等组成的电气回路，其核心作用是建立安全可靠的电气参考基准，并构成高压回路，确保车辆电气系统稳定、安全地运行；动力电池接地线束上通常设置有护套管，导线被保护在护套管内，使得导线不易因挤压、冲击或摩擦而损坏；现有的动力电池接地线束的护套管通常采用热缩管与导线固定，但是当护套管损坏而需要更换时，需要在新换上的护套管与导线之间套上热缩管，然后采用加热设备加热热缩管，才能使新换上的护套管与导线固定，随着更换次数的增多，导线与护套管的连接处被被多次加热，导线内的热应力逐渐积累，容易导致导线损坏；因此，研发一种动力电池接地线束来解决上述问题很有必要
Benefits of technology
[0009]本实用新型的有益效果是：本实用新型利用锁定组件将护套管与动力电池接地线束的导线装在一起，取代了常规的利用热缩管将护套管与导线装在一起的方式，从而使更换护套管时，无需利用加热设备加热热缩管，电池接地线束的导线在更换护套管的过程中不会积累热应力，从而避免电池接地线束的导线因为热应力的过度积累而损坏。
