Preface

In the complex system of automobile, wire harness plays a vital role.

They are not only the physical bridges connecting various electronic components, but also the key to ensure the safety and performance of vehicles.

1. Side airbag wire harness

The side airbag wire harness is the core part of the automobile safety system.

They must have high reliability and fast response ability in order to activate airbags quickly in the event of a collision and protect passengers.

Technical requirements include:

Heat resistance: Wire harness materials should be able to withstand high temperatures to ensure stability when working near the engine.

Anti-interference: Wire harness design needs to reduce electromagnetic interference to ensure clear signal transmission.

2. Door wire harness

The door wire harness is responsible for connecting the electrical equipment on the door, such as window lifter, door lock and so on.

Their characteristics and requirements are as follows:

Wear resistance: Frequent door switch movements require high wear resistance of wire harness materials.

Flexibility: The wire harness should be designed to adapt to the movement of the door and not be damaged by bending.

3. Rear body wire harness

The rear body wire harness is connected to the lighting and signal system at the rear of the vehicle.

Its technical requirements include:

Waterproof: As the rear body wire harness may be exposed to bad weather, it needs to have good waterproof performance.

Chemical resistance: Wire harness materials should be resistant to chemicals such as detergents and fuel.

4. Front wire harness

The front wire harness is the key to connect the front electrical equipment of the vehicle, such as headlights, turn lights and so on.

Its technical features are as follows:

Temperature resistance: The front wire harness should be able to withstand the high temperature environment of the engine compartment.

Anti-vibration: Due to the vibration of the vehicle when driving, the wire harness should have good anti-vibration performance.

5. Roof wire harness

The roof wire harness connects the lighting and decoration equipment on the roof.

Technical requirements include:

Concealment: The wire harness design should be concealed as far as possible and will not affect the beauty of the vehicle interior.

Lightweight: In order not to increase the weight of the car, the wire harness material needs to be lightweight.

6. Engine wire harness

Engine wire harness is one of the most complex and critical wiring harness in automobile. It connects multiple sensors and control units of the engine.

The technical requirements are:

High temperature resistance: It must be able to withstand the high temperature generated by the engine.

High reliability: The connection of the wire harness must be very stable to ensure the accurate operation of the engine control system.

7. Main wire harness

The main wire harness is the core that connects the main electrical systems of the vehicle.

Its characteristics and requirements are as follows:

High load capacity: The main wire harness should be able to withstand high current load.

Safety: The design should comply with strict safety standards to prevent short circuit and fire.

8. Oil tank wire harness

The fuel tank wire harness is connected to the fuel system and is responsible for the transportation of fuel.

Its technical requirements include:

Explosion-proof: Wire harness materials should have explosion-proof properties to prevent danger in the event of fuel leakage.

Corrosion resistance: The wire harness should be able to resist the chemical corrosion of oil products.

9. Dashboard wire harness

The dashboard wire harness connects various indicators and control buttons on the dashboard.

The technical requirements are:

Accuracy: The wire harness needs to ensure the accuracy of the dashboard display.

Durability: Due to frequent use, the wire harness needs to be very durable.

Conclusion

The design and manufacture of automobile wiring harness is a highly specialized field, and every detail is related to the performance and safety of the vehicle.

With the development of automotive technology, the design of wire harness is also improving to meet higher performance requirements and more stringent safety standards.

The next time you sit in your car, imagine these invisible wire harnesses, which are the link between car safety and technological progress.
