Problems solved by technology

The connection between the two ends of the traditional automotive wiring harness and the terminals connected to it is relatively loose, and the compact effect cannot be achieved, which not only makes the impedance of the wiring harness itself high, but also increases the impedance after connecting the terminals
However, due to the narrow installation space of the automotive wiring harness, the wire diameter of the wiring harness is generally small. If the impedance at the terminal is increased on this basis, the overall loss of the air conditioner will undoubtedly increase when the air conditioner is working, resulting in an increase in the power consumption of the car. Increase the burden on the wiring harness
The narrow installation space is not conducive to heat dissipation, and the working conditions of the wiring harness are poor. If the resistance of the wire increases, more heat will be generated, which will not only bring negative effects on the service life of the air conditioning equipment and wiring harness, but also create safety hazards for the overall operation of the car.

Abstract

The invention discloses a crimping process of an automobile wire harness, which uses a stamping device to crimp the terminal and the automobile wire harness body together, comprising the following technological steps: deoxidizing the wire harness after the wire is opened and drying at a high temperature after the deoxidizing treatment; First, the whole crimping height is adjusted by using the coarse adjusting lever, and then the crimping height is slightly adjusted by using the fine adjusting lever; the wire harness is put into the mold limiting groove, the punching switch is turned on for crimping, and the wire harness and segments after crimping are treated by electroplating anti-corrosion; an electronic tension tester is used to test the tension between the wiring harness body and the terminal, and detect the metallography, voltage drop and contact impedance of the terminal.

Description

technical field [0001] The invention relates to the technical field of wire harnesses, in particular to a crimping process for automobile wire harnesses. Background technique [0002] The automotive wiring harness is a special wiring harness used to supply power to the air conditioner installed in the car and transmit control signals. The connection between the two ends of the traditional automotive wiring harness and the terminals connected to it is relatively loose, and the compact effect cannot be achieved, which not only makes the impedance of the wiring harness itself high, but also increases the impedance after connecting the terminals. However, due to the narrow installation space of the automotive wiring harness, the wire diameter of the wiring harness is generally small. If the impedance at the terminal is increased on this basis, the overall loss of the air conditioner will undoubtedly increase when the air conditioner is working, resulting in an increase in the po...
