Automotive wiring harness is an important part of the automotive electrical system, which provides stable power supply and signal transmission. It consists of multiple wires that are tied together through insulated sleeves or insulated tapes to form a single unit. The role of the automotive wiring harness is to transmit power from the power source to each electrical device and to transmit signals to the control module to realize the normal operation of each system of the car.
Composition and structure of automotive wiring harness
Automotive wiring harness consists of wires, insulating sleeves, connectors and connectors. The wires are the core part of the wiring harness, which carries out the task of power and signal transmission. Insulation sleeve or insulation tape is used to tie the wires together, play a protective and fixed role. Connectors and connectors are an important part of connecting the wiring harness to the equipment, and they are plugged and unplugged to realize the transmission of power and signals.
Process of making automotive wiring harnesses
The process of making automotive wiring harnesses includes steps such as designing, stripping, braiding, soldering, insulating and packaging.
First, the length and layout of the wiring harness are determined according to the design requirements of the electrical system of the car. Then, the wires are stripped of a certain length of insulation to expose the conductor portion. Next, multiple wires are braided together and secured with insulating sleeves or insulating tape according to the design requirements. Take care to insulate the wires from each other when braiding to avoid short circuits and interference.
After completing the braiding, the wires are soldered to ensure the unobstructed transmission of power and signals. Then, insulate the soldered parts, using insulating tape or insulating sleeves to wrap the soldered points to prevent leakage and short circuit.
Finally, the entire harness is packaged, using a protective sleeve or protective tape to completely wrap the harness, playing a protective and fixed role. When packing, pay attention to the layout and direction of the harness to avoid friction and interference with other parts.
Maintenance and Troubleshooting of Automotive Wiring Harnesses
Maintenance of automotive wiring harnesses is an important part of ensuring the normal operation of the automotive electrical system. Regularly check the connectors and connectors of the wiring harness to ensure that they are tight and reliable, free of looseness and corrosion. Check whether the insulation of the wiring harness is intact, there is no wear and tear and cracks. If problems are found, replace or repair them promptly.
Wiring harness troubleshooting is needed when the car has an electrical system failure. First, check whether the connection of the wiring harness is loose or corroded, if there is a problem, promptly tighten or replace the connectors and connectors. Then, check whether the insulation of the wiring harness is intact, there is no wear and tear and cracks, if there is a problem, repair or replace. Finally, use test instruments to conduct resistance and short circuit tests on the wiring harness to find out the point of failure and repair.
