Abstract

本申请实施例提供了一种汇流构件、电池及用电设备，涉及电池技术领域。汇流构件，包括第一连接部，用于连接第一电池单体的第一电极端子；第二连接部，用于连接第二电池单体的第二电极端子；多个熔断部，每个熔断部的一端连接第一连接部，另一端连接第二连接部；其中，多个熔断部中过流截面积最大的一个所对应的过流截面积为Smax，多个熔断部中过流截面积最小的一个所对应的过流截面积为Smin，Smin和Smax满足下述关系式：0.3≤Smin/Smax≤1。所有的熔断部中的最小过流截面积Smin和最大过流截面积Smax满足：0.3≤Smin/Smax≤1，在短路时，汇流构件的熔断部熔断时间较小，从而减小出现短路的时间，避免因长时间短路，熔断部在熔断的过程中拉弧能量积聚。
