1. Body wiring harness: It runs from the left side of the cab against the floor and connects the fuel tank sensor and rear taillight.
2. Engine wiring harness: connects various sensors and actuators on the engine and surrounds the engine.
3. Instrument panel wiring harness: Connect to the body or chassis wiring harness, and run along the pipe beam to connect various electrical devices on the instrument panel, such as instrument clusters, air conditioning switches, radios, cigarette lighters, etc.
4. Door wiring harness: Connect all electrical devices on the inner door panel, such as central locks, glass lifters, speakers, etc.
5. Front panel wiring harness: From the cab, connect the front panel's electrical components such as side turn signals, front combination lights, horns, electronic fans, etc. along the fenders and front bumper frame.
6. Automobile wiring harnesses are generally designed into H-type and E-type, and simpler ones are also designed into T-type.
The development status of the automotive wiring harness industry
my country's automotive industry is developing rapidly. Automobile production increased from 8.89 million units in 2007 to 13.79 million units last year, especially in 2009, which increased by 48.2% over the previous year. It is expected that by 2010, my country's automobile production will exceed 15 million vehicles. The factors that promote the development of my country's automobile wiring harness industry through automobile production still exist.
The development of China's car industry is basically based on introduction. The introduction of vehicle models determines that wire harness production can only be imitation or equivalent development. Therefore, the technological development of automobile wiring harness has always lagged behind that of the entire vehicle. develop. At present, the popularization, safety and applicability of Chinese cars are the main ones, so the technology of automobile wiring harness will remain at the current level. However, as cars become more family-oriented, the configuration requirements for cars will become more and more diversified, complex and complex. Non-standardization, the situation of wire harness factories producing tens of thousands or even hundreds of thousands of identical wire harnesses will be broken. The use of non-metallic conductive materials will be broken. The production of integrated modules will be the first topic to be studied by wire harness factories in recent years.
Due to the advent of fully automatic high-performance crimping machines with detection, the new puncture splicing process, the improvement of new equipment, as well as the frequent changes in vehicle engineering and the shortened supply cycle, traditional, workshop-style, manual The controlled wire harness production method will gradually be eliminated. Therefore, improving independent development capabilities, conducting parameter design, system design, and maintaining synchronization with vehicle design are the main development directions of China's automotive wiring harness industry. With the diversification of wiring harness functions, vehicle manufacturers will require parts factories to provide appropriate spare parts in real time, which will also completely break the traditional production and supply methods.
At present, the more powerful wire harness factories have gathered at the location of the vehicle manufacturer to adapt to rapid response requirements. In the United States and Europe, the supply time limit of wire harness factories has been shortened to ninety minutes, which requires A wire harness factory must not only have a rapid-response technical management system and a reliable quality assurance system, but also a smooth material system and a staff training system. The format of China's sedan production base has basically taken shape. Driven by the OEMs, it has become a base for large-scale production of wire harnesses. Wire harness production in Northeast and East China accounts for more than 63% of the national market, and its sustainable development capabilities are also better than other areas.
