Structure and Application Copper foil soft connection is made up of multiple pieces of T2 purple copper foil stacked and welded to both ends. Drilling can be carried out according to customer requirements. Molecular diffusion welding is a precision welding technology that promotes mutual diffusion and bonding between atoms of a workpiece under high temperature and pressure conditions. A high-strength joint is formed while maintaining no visible deformation of the workpiece.
Therefore, copper foil soft connection is an excellent electrical conductor and is usually used in related industries such as new energy vehicles, wind power generation, photovoltaic energy storage, electric locomotives, and complete transmission and distribution.
Customized production can be customized based on customer drawings/samples and provided systematic service support
Automotive electronic control connection: outstanding performance of new energy soft connection
Among the core technologies of new energy vehicles,electric control systemIt plays a vital role. It is the “brain” and “nerve” of the vehicle, controlling all aspects such as power output, energy management, and intelligent driving. The key to connecting these precision electronic control units is high-performanceNew energy soft connection。We focus on providing customized soft connection solutions to ensure that your new energy vehicles can have excellent performance and reliability under complex operating conditions.
Why do new energy vehicle electronic control systems need soft connections?
Compared with traditional fuel vehicles, the electronic control system of new energy vehicles is more complex and integrated, and the requirements for connecting parts are more stringent:
- High-voltage and high-current transmission: The power battery system of new energy vehicles usually works in a high-voltage and high-current environment (hundreds of volts, hundreds of amperes). Soft connections require extremely low resistance and excellent current-carrying capacity to reduce energy loss and heat generation.
- complex electromagnetic environment: High-voltage systems are prone to electromagnetic interference. The optimized design of soft connections helps reduce electromagnetic compatibility (EMC) problems, ensure the purity of signal transmission and the stable operation of the electronic control system.
- vibration and shock: While the electric vehicle is driving, vibration from the motor, road surface and battery pack will continue to be transmitted. The flexible nature of soft connections can effectively absorb and disperse these mechanical stresses, avoid fatigue fractures that may be caused by hard connections, thereby extending the service life of key components.
- Thermal expansion and contraction compensation: Batteries and power modules will heat up while working and cool down when parked. This temperature change will cause the material to expand and contract. Flexible soft connections can effectively compensate for this deformation and avoid damage caused by internal stress at the connection.
- Compact spatial layout: New energy vehicles have extremely high requirements on space utilization, and the layout of electronic control units and wiring harnesses is often very compact. The bending and twisting capabilities of soft connections allow them to adapt to narrow installation spaces and complex wiring paths.
- high reliability and safety: Failure of any electronic control connection may lead to vehicle performance degradation and even safety hazards. New energy soft connections must have excellent corrosion resistance, high temperature resistance, flame retardant and other characteristics to ensure stable connection under extreme conditions.
Features of our new energy vehicle electronic control soft connection products
The electronic control soft connection products we provide for new energy vehicles are specially designed to meet the industry’s stringent standards and have the following core advantages:
- Extreme flexibility and vibration resistance: It is laminated with multiple layers of high-purity electrolytic copper foil. The structure is precise, giving the product excellent flexibility. It can effectively absorb vibration and impact during vehicle operation, reduce stress concentration, and significantly improve the durability of connections and electronic control modules.
