Automobile harness is the main body of automobile circuit network, without which there is no automobile circuit. Wire harness refers to the connection between the contact terminal (connector) made of copper material and the wire and cable, and the external plastic insulator or external metal shell is used for the assembly of connecting circuit. The harness industry chain includes wire and cable, connector, processing equipment, harness manufacturing and downstream application industries. The harness is widely used in automobile, household appliances, computer and communication equipment, various electronic instruments, etc. the body harness is connected to the whole body, and the body shape is H-shaped.
Ultrasonic wire harness welding is a common process of automobile wire harness welding at present. Its principle is to reconstruct the surface of welding materials by high frequency vibration. Ultrasonic welding has the advantages of low energy consumption, no pollution, solid welding, low internal resistance, etc., does not change the chemical properties of welding parts, and has excellent welding conductivity.
