Automotive wiring harness refers to the copper connector made of contact with the terminal (connector) and wire and cable crimp, the outside and then plastic pressure insulator or external metal shell, wire bundles to form the connection circuit components, is the car interior The basic carrier of communication.
According to the car area and function, the wiring harness can be divided into
1) engine harness, connected to the engine on a variety of sensors and actuators, around the engine around.
2) dashboard wiring harness, connected with the body or chassis harness, along the pipe beam to connect the instrument panel on a variety of electrical devices such as instrumentation, air conditioning switch, Shoufang Ji, cigarette lighter and so on.
3) body wiring harness, usually from the left side of the cab close to the floor walking, connecting the tank sensor and rear taillights.
4) door harness, connect all the electrical components on the door panel, such as central locking, glass lifter, speakers and so on.
5) Front bumper beam, from the cab over, along the fender and the front bumper frame to connect the front of the electrical components such as side turn lights and front combination lights, speakers, electronic fans.
Automotive wiring harness can be applied to the engineering plastics are connectors, fasteners, fuse boxes and other components, the main use of materials for the PA heat-resistant grade, PA toughening grade, PA + glass, mineral powder, glass beads enhanced level, As well as PBT, PPO and so on.
Automotive harness industry development is highly dependent on the automotive industry, most of the current brand depot has its own relatively complete and complete car supply chain, wire harness industry manufacturers and car companies are relatively more closely integrated.
Mainstream enterprise enterprise wiring harness supplier concentration is high
Domestic large-scale independent brand depot most have specialized supporting the production of the harness plant. And foreign investment and joint venture vehicle factory, the wiring harness requirements are relatively high, the choice of wire harness manufacturers are still international giants in China's wholly-owned or joint venture manufacturers.
China 's automobile harness competition pattern
As the production of automotive wiring harness on the connector supporting capacity is relatively high, benefit from the market on the supply of high-quality automotive connector products gradually increased, automotive wiring harness manufacturers rely on their own connector technology corresponding decline in automotive wiring harness production access threshold decreases. At present, the emergence of a number of outstanding domestic wiring harness business.
At present, although many domestic automotive wiring harness manufacturers, but most of the small, R & D capability is weak, backward production equipment, quality grade is not high, supporting models of a single, mainly for their own brands in the package. Domestic harness for low-grade cars equipped with high-grade, high-quality wiring harness market demand.
Comparison of R & D Capability of Automobile Harness Enterprise at Home and Abroad
Automotive wiring harness market and the development of the automotive market is closely related, according to industry experts predict the current cost of cycling harness about 3,500 yuan, assuming that China's automobile production and sales by 2020 to reach 30 million (wiring harness costs and new energy and intelligent enhance the impact of the impact of reduced beam , The cost of cycling harness remains unchanged), then the market space of up to 100 billion yuan. According to China's industrial information network data, 2015 automotive wiring harness independent permeability of about 10%, assuming that the independent brand wiring harness penetration in 2020 increased to 20%, then the autonomous automotive wiring harness market space from the current about 80 billion to 20 billion yuan.
2020 self-brand harness market space is expected to exceed 20 billion yuan
