Harness classification

1. Body wire harness: Walk from the left side of the cab against the floor and connect the fuel tank sensor and the rear taillight.

2. Engine harness: It connects various sensors and actuators on the engine and surrounds the engine.

3. Instrument panel wiring harness: it is connected with the wiring harness of the car body or chassis, walks along the pipe beam, and connects various electrical equipment on the instrument panel, such as combination instrument, air conditioner switch, radio and player, cigarette lighter, etc.

4. Door harness: Connect all electrical equipment on the door inner panel, such as central locking, glass lifter, speaker, etc.

5. Front-wall wiring harness: It comes from the cab and connects the front-wall electrical equipment, such as side turn lights and front combination lights, speakers, electronic fans, etc. Along the fender and front bumper frame.

6. automotive wiring harness is generally designed as H-type and E-type, and the simpler ones are also designed as T-type.

The Development of automotive wiring harness Industry

China's automobile industry is developing rapidly. Automobile production increased from 8.89 million in 2007 to 65.438+0.37 million last year, especially in 2009, an increase of 48.2% over the previous year. It is predicted that by 20 10, China's automobile output will exceed150,000, and the factors that promote the industrial development of automotive wiring harness in China still exist.

The development of China's automobile industry is basically based on import, and the introduction of automobile models determines that the harness production can only be imitated or developed equally, so the technological development of automotive wiring harness has been lagging behind the development of the whole vehicle. At present, the popularity, safety and applicability of domestic automobiles are the main types, so the technology in automotive wiring harness will maintain the current level. However, with the family of cars, the requirements for car configuration will become more and more diversified, complicated and non-standardized. The situation that the harness factory produces tens of thousands or even hundreds of thousands of identical harnesses will be broken, and the use of non-metallic conductive materials will be broken. The production of integrated module will be the first research topic of wire harness factory in recent years.

Due to the appearance of automatic high-performance crimping machine with inspection, the perfection of new piercing technology and new equipment, the frequent changes of vehicle engineering and the shortening of delivery cycle, the traditional, workshop-style and manual production methods of wire harness will be gradually eliminated. Therefore, improving the ability of independent development, carrying out parametric design and systematic design, and keeping pace with vehicle design are the main development directions of China automotive wiring harness industry. With the diversification of wire harness functions, the automobile factory will require the parts factory to provide suitable parts immediately, which will completely break the traditional production mode and supply mode.

At present, the more powerful wire harness factories are assembled at the location of the automobile factory to meet the requirements of rapid response. In the United States and Europe, the delivery time of wire harness factory has been shortened to 90 minutes, which requires wire harness factory not only to have a fast technical management system and a reliable quality assurance system, but also to have a smooth material system and staff training system. The format of China automobile production base has basically taken shape. Driven by the automobile factory, it has become a base for mass production of wire harnesses. The output of wire harness in Northeast China and East China accounts for more than 63% of the national market, and its sustainable development ability is superior to other regions.
