The need for new energy vehicles to be disassembled infrequently during their life cycle is not considered, and a quick-plug solution is used, resulting in the need to increase interlock monitoring and complex functions; 3. The structural design is complex, and the application is single, and the installation and wiring method is single; 4. The product structure has poor strength, does not meet complex vehicle conditions, and is prone to energy transmission failure, causing danger to passengers; 5. The range of compatible wire diameters is small, and multiple selections are required; 6. The product volume is large, occupying space in the car, and the current-carrying performance of the terminals arranged in the same volume cannot meet the requirements. Utility Model Content
