The wiring harness is the main body of the network of automotive circuits, without the harness, there would be no automotive circuit, the harness becomes the same, it is made of copper punching and contact parts terminals (connectors) and wire and cable crimping, and then outside the plastic pressure insulator or additional metal shell to bundle the harness to form the components connected to the circuit. The wiring harness plays a vital role as a carrier for the connection of various parts of the automobile circuit. It must not only accurately transmit various signals, but also ensure the reliability of the connected circuits and requires a certain level of anti-interference capability, which determines the rigors of automotive testing. So do you know the importance of public transportation wiring harness for public transportation? Let me give you a detailed introduction!
Here is the content list:
The importance of the excellent performance of the wiring harness
Reliability of wire harnesses
Imagine if the wiring harness inside the engine compartment of public transportation can not withstand the high temperature, the shell can not be anti-corrosion and flame retardant, the public transportation wiring harness in the cabin spontaneous combustion is how tragic? If the wiring harness at the door hinge does not go through the fatigue endurance test, then the doors and windows can still be opened and closed freely? There are some wiring harnesses from the chassis, equivalent to direct exposure to the external environment, environmental aging test is not escaped. Public transport recalls due to wiring harness problems occur from time to time. Public transportation wiring harness testing projects include appearance testing, electrical harness line size measurement, terminal, and the wire connection, contact testing, rubber parts waterproof performance, electrical performance, temperature resistance, humidity resistance, vibration resistance, salt spray resistance, chemical resistance, etc.
The application scenarios of public transportation cables are mainly in the car line, charging gun, charging pile, and three cases of charging with the car. Compared with traditional fuel vehicles, new energy vehicles have higher requirements for wiring harness delivery capacity, mechanical strength, insulation protection, and electromagnetic compatibility. At present, public transportation usually uses up to 600V or higher drive voltage, which is much higher than the 12V voltage of fuel cars, requiring stronger voltage resistance and sealing of the wiring harness to avoid burning accidents caused by short-circuiting of high-voltage lines after public transportation encounters a collision. In addition, the application of public transport is AC motor, electromagnetic interference is more intense, the design of public transportation wiring harness must consider electromagnetic interference to ensure the reliability of the harness application.
Public transportation wiring harness is the fastest growing industry in today's electronic and information era, the market demand is the largest, one of the most convenient products to install. From popular household appliances to communications equipment, computers, and external devices, as well as security, solar energy, aircraft, automotive and military instrumentation are widely used wiring harnesses. So do you now know the importance of public transportation wiring harnesses? I hope this little article can be of help to you!
