The automotive Wiring Harness is an important part of the vehicle's electrical system. It connects various electrical devices together to achieve the normal operation of the vehicle's electrical system. Automotive wiring harnesses are usually composed of a variety of wires, Connectors, insulating tubes, etc., to ensure the stable transmission of electrical signals and the safe use of electrical equipment. This article will introduce the basic structure, manufacturing process and application fields of automotive wiring harnesses.
1. The basic structure of automobile wiring harness Automotive wiring harnesses are usually composed of wires, connectors, insulating tubes and harnesses. Wires are the basic building blocks of wiring harnesses, usually consisting of copper conductors and insulation, used to transmit electrical signals. Connectors are an important part of connecting wires together. It usually consists of metal joints and sleeves to ensure the stable transmission of electrical signals and the firmness of connections. Insulating tubes are an important part of protecting wires and connectors. It is usually made of materials such as plastic or rubber to prevent damage to electrical equipment such as water, dust and vibration. The harness is an important part of wrapping the entire wiring harness together. It is usually made of materials such as plastic or rubber to protect the wiring harness from the external environment. 2. Manufacturing process of automobile wiring harness The manufacturing process of automotive wiring harness usually includes the steps of designing, cutting, stripping, twisting, welding, insulating, wrapping and testing. Design is the first step in making a Wire Harness. It needs to determine the length of the wire harness, the number of wires, the type of connector, and the insulating material according to the requirements of the vehicle electrical system and the environment in which the wire harness is used. Cutting is the step of cutting materials such as wires and insulating tubes according to design requirements. Stripping is the removal of insulation from wires for operations such as twisting and soldering. Stranded wire is multiple wires twisted so that they can be connected to the same connector. Welding is to weld connectors and wires to ensure stable transmission of electrical signals. Insulation is to insulate connectors and wires after welding to prevent electrical signal interference and external environment damage. Wrapping is to wrap the entire wire harness to protect the wire harness from the interference of the external environment. The test is to conduct an electrical test on the fabricated wire harness to ensure the quality and stability of the wire harness. 3. Application fields of automotive wiring harness Automotive wiring harnesses are widely used in automotive electrical systems, including engine control systems, body control systems, chassis control systems, and entertainment systems. The engine control system is the most important part of the vehicle's electrical system, including the ignition system, fuel system, emission system and fault diagnosis system. Body control systems include lights, air conditioning, power windows, audio and airbags. The chassis control system includes braking system, steering system and suspension system. The entertainment system includes radio, CD player, navigation system and rear-view camera. The quality and stability of the automotive wiring harness directly affect the normal operation and driving safety of the vehicle electrical system, so it needs to be strictly checked and tested during the production and use process. In short, the automotive wiring harness is an indispensable part of the vehicle electrical system, and its quality and stability are directly related to the safety and performance of the vehicle. With the continuous development and upgrading of automotive electrical systems, automotive wiring harnesses will also continue to innovate and improve to meet the needs of automotive electrical systems.
