Mobile WebSiteAutomotive wiring harness is the main body of the car circuit, belonging to the automotive electrical system connection components, as if the human nerve and blood vessels, the various functional parts connected through. The following is a comprehensive analysis of the industrial chain for the automotive wiring harness, including: the principle of overview, production technology, material market introduction, development trend analysis, market size analysis, market structure analysis.
Harness is made of copper by the contact with the terminal (connector) and wire and cable crimp, the outside and then plastic pressure insulator or external metal shell, etc., to form a wiring harness bundle connection components. In short, is to connect the car electrical wiring, car operating conditions and parameters are reflected through the wiring harness in the car above the computer. On the other hand, the electronic technology of automotive wiring harness has become an important indicator of vehicle performance
Classification of automotive wiring harnesses
Automotive wiring harness can be divided into two kinds of main harness and small harness. The main harness includes engine harness, central box box harness, dashboard harness, cockpit harness, etc .; and small harness includes door harness, battery harness, ABS brake wire harness and so on.
In addition, according to the voltage distinction, the car harness can be divided into high-voltage wiring harness and low-voltage wiring harness. Automotive high-voltage line is characterized by the largest high-voltage low-current, high insulation performance requirements, so the insulation is often thick and the core is relatively small.
The production process of automobile wiring harness
Automotive wiring harness production process mainly open, crimping, preload, assembly, etc., the main material of the wiring harness for the heat shrink material, automotive wiring harness is an important insulating material. Domestic thermal materials for automotive manufacturing market share is still very low, only about 20%.
Comparison of the price of thermal materials at home and abroad
Development Trend of Automobile Harness
With the development of automotive electronics, economy, comfort, reliability, etc. will be more and more prominent, the requirements for the wiring harness gradually higher. The domestic automotive wiring harness market will be gradually reduced from low-cost strategic market technology to a higher cost-effective market. Automotive wiring harness is also moving towards high pressure, lightweight, standardized direction.
With the gradual increase of electronic equipment, wire harness light weight is gradually taken seriously, mainly from the harness components of the material, miniaturization and internal layout, etc. to study
Analysis of Market Size of Harness Industry
At present, China's domestic wiring harness most of the foreign joint ventures or joint ventures, accounting for 42% of China's wire harness industry, private enterprises accounted for about 37%. Automotive wiring harness market concentration is higher.
With the development of automotive electric, intelligent driving, car networking, the domestic automotive wiring harness industry scale will grow further. Domestic self-harness business will also be with the cost of decline, technological breakthroughs, the market scale has steadily expanded.
