The main function of the connector is to ensure effective electrical connection between the cells, thereby enabling current transmission and voltage aggregation. The "flexible connector for an energy storage battery module" disclosed in application number "202020321954.3" is an increasingly mature technology. This flexible connector, due to its bending adjustment section, allows for adjustment of the height difference and electrode spacing between batteries within the energy storage battery module, reducing the damage caused by cell expansion. Furthermore, it includes stacked copper layers, which have strong current-carrying capacity. The connector body used in the energy storage battery module... While the connector allows for safe passage of high currents without interference between components, it also has the following drawbacks: Although the flexible, bendable connector facilitates the connection of energy storage battery modules, its simple structure limits its use to a fixed number of modules. Therefore, it is necessary to provide a connector whose size can be adjusted according to the number of energy storage batteries in the module, enhancing its versatility. Furthermore, the current connector structure is inconvenient for assembling and disassembling components, and its conductive nature hinders heat dissipation. Therefore, it is essential to provide a connector that facilitates assembly and disassembly of components, allows for heat dissipation, and improves ease of use. Utility Model Content
