[0002] The domain control connector for new energy vehicles is a key component that has emerged with the upgrade of new energy vehicle electronic and electrical architectures and the development of a centralized domain architecture. With the use of domain controllers, the demand for connectors has also changed, especially in terms of miniaturization, modularization, and centralization. The disadvantages of domain control connectors in traditional new energy vehicles are: 1. They are usually multiple single connectors with poor integration; 2. High-current terminals are still machined, which is costly; 3. Connector sockets still use copper busbars for lap connection or wire swinging, which takes up a lot of space in the box and makes wiring harness assembly difficult; 4. The structure is complex, and the wiring harness can only be routed horizontally at 180 degrees; 5. The structural strength is poor and cannot meet complex vehicle conditions; 5. The range of compatible wire diameters is small, requiring multiple selections and matching; 6. Similar products are bulky. Utility Model Content
