Application case of ultrasonic wire harness terminal welding


Ultrasonic welding is a commonly used technology for automobile wire harness. Its principle is that the surface of welding materials is recombined by ultrasonic high-frequency vibration. This technology has the advantages of low energy consumption, no pollution, firm welding, low internal resistance, and no change of metal structure. The conductivity of the finished metal is basically no loss, far better than the general soft welding, and its performance is far better than the press bonding process.



The ultrasonic metal welding technology provides a reliable guarantee for the wiring harness connection inside the automobile. After welding, the electric connection system of the automobile can be stable and reliable. The internal resistance of the welding joint of the wire harness is low, and the temperature rise is low.


  With the popularity of environmental protection new energy vehicles, and new energy electric vehicles are driven by electric vehicles. New energy vehicles have higher requirements for electrical connection. The driving range of new energy vehicles is higher and higher, and the charging speed is faster and faster. The temperature rise of traditional pressing process under high voltage and large current is too high, which directly affects the safety of automobile power system. Ultrasonic metal welding can solve this problem perfectly.
