When the production line equipment is testing the battery pack offline, there are scenarios of frequent plugging and unplugging of large currents and long-term continuous operation. This puts higher requirements on the economy, convenience and durability of cable connectors. However, the existing original standard connectors cannot meet the frequent plugging and unplugging requirements. For this reason, the company has independently developed a modular, easy-to-maintain, highly convenient and integrated interlocking interface profiling tooling series, and can be customized according to the different interface types of customers, which significantly improves the durability and maintenance convenience of the interface connector and reduces the customer’s use cost.
