What is an Automotive Wiring Harness?
An automotive wiring harness is a set of integrated wires, cables, terminals, connectors and protective sleeves used to connect and transmit signals and power to various electrical systems of a car to ensure the normal operation of various electronic devices.
Features of automotive wiring harnesses
High integration: multiple wires, connectors and terminals are integrated into one structure to optimize circuit layout.
High reliability: high temperature resistant, waterproof, anti-interference and other materials are used to adapt to the complex environment of the car.
Standardization and customization coexist: it can be customized according to different models and functional requirements, while complying with industry standards.
Lightweight design: new wire materials and optimized wiring structure are used to reduce the weight of the car and improve fuel economy.
Advantages of automotive wiring harnesses
Improve production efficiency: pre-assemble the wiring harness, simplify the installation process, and improve assembly efficiency.
Reducing the failure rate: using standardized production to reduce problems such as poor contact that may be caused by manual wiring.
Improve safety: insulation protection and short circuit protection design reduce the risk of electrical failure.
Support intelligence: meet the needs of new energy and intelligent networked vehicles for high-voltage wiring harnesses and data transmission harnesses.
Scope of use of automotive wiring harnesses
Traditional fuel vehicles: engines, lighting, instruments, electronic control systems, etc.
New energy vehicles: high-voltage wiring harnesses, power battery management, charging interfaces, etc.
Intelligent connected vehicles: ADAS (Advanced Driver Assistance System), in-vehicle entertainment systems, etc.
Other vehicles such as engineering machinery, motorcycles, and electric vehicles.
Customized services are supported
Wire harness length, specifications, and materials are optional to meet the needs of different models.
Terminals and connectors are optional, and specific brand matching is supported.
Special function customization, such as waterproof, fireproof, shielding and anti-interference, etc.
Mass production or small batch trial production support, sample testing services are provided.
FAQ
Q1: What certifications do your automotive wiring harnesses support?
A1: Our wiring harnesses comply with international quality management system certifications such as ISO 9001 and IATF 16949, and can provide relevant certifications such as UL and CE to ensure that the products meet industry standards.
Q2: Can you provide OEM/ODM customization?
A2: Yes, we support OEM/ODM customization. We can design, select materials, and produce according to customer needs, and provide sample testing.
Q3: What is the delivery cycle of the wiring harness?
A3: Standard products are usually delivered in 7-15 days, and customized products are generally 15-30 days depending on the complexity of the design. We can adjust the production plan according to urgent orders.
Q4: How to ensure the quality of the wiring harness?
A4: We use fully automatic production equipment and conduct 100% conduction test, insulation test, high temperature aging test, etc. to ensure the stability and durability of the product.
Q5: What are the common wiring harness failures and maintenance methods?
A5:
Poor contact: Check whether the connector is loose and the terminal is oxidized. If necessary, replace the terminal or wiring harness.
Short circuit or open circuit: Use a multimeter to detect the line resistance. If abnormal, replace the damaged wire or insulation layer in time.
Wire aging: Regularly check whether the surface of the wiring harness is worn or aged, and replace it if necessary.
Damp or water ingress: Ensure that the waterproof cover is well sealed, dry it in time if water ingress is found, and check for corrosion.
Q6: What are the special requirements for high-voltage wiring harnesses of new energy vehicles?
A6: High-voltage wiring harnesses of new energy vehicles require high temperature resistance, high voltage resistance, shielding and anti-interference, and use special high-voltage connectors to ensure driving safety and stable power transmission.
