Patent number: 11942647Abstract: The present application relates to a harness isolation plate assembly, a battery module, a battery pack and a device. The harness isolation plate assembly includes a plurality of isolation units comprising busbars and insulating films connecting the busbars; and a connecting assembly through which the adjacent isolation units are connected. In the present application, the harness isolation plate assembly includes a plurality of separate isolation units. Upon molding, each isolation unit can be processed independently. Moreover, a size of each isolation unit is small, thus reducing processing difficulty. Furthermore, it is easy to control a location of each busbar, such that locating accuracy of the busbars is improved so as to enhance connecting reliability between the busbars and an electrode lead. Meanwhile, in each isolation unit, the busbars are connected through the insulating films, such that a risk of short circuit for the busbars is low.Type: GrantFiled: December 28, 2021Date of Patent: March 26, 2024Assignee: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Xuguang Wang, Jihua Yao
