Mobile WebSiteThe car wiring harness is the main body of the car circuit, and there is no car wiring for the wire harness. The wire harness refers to a member in which a contact terminal (connector) made of a copper material is crimped to a harness cable, and then an externally molded insulator or metal case is bundled by a wire harness to form a connecting circuit. The wire harness industry chain includes wire harness cables, connectors, processing equipment, wire harness manufacturing and downstream applications. Wire harness applications are widely used in automobiles, home appliances, computers and communication equipment, various electronic instruments, etc. The fuselage harness connects the entire body. The general shape is H-shaped.
The harness map should be drawn before the harness is laid out. The harness diagram is different from the schematic. The circuit diagram is an image showing the relationship between various electrical components. It does not reflect how the electrical components are connected to one another and is not affected by the size and shape of the individual electrical components and the distance between them. The harness diagram must take into account the size and shape of the individual electrical components and the distance between them, and how the electrical components are connected to each other.
After the technician of the wire harness factory manufactures the wire harness wiring board according to the wire harness diagram, the worker cuts the wire according to the wiring board. The main vehicle harnesses are generally divided into engines (ignition line, EFI, power generation, start-up), instrumentation, lighting, air conditioners, auxiliary electrical components, and main harnesses and branch wiring harnesses. The complete vehicle main harness has multiple branch harnesses, like branches and branches. The main vehicle harness is typically centered on the dashboard and extends forward and backward. Due to the length relationship or ease of assembly, some automotive wiring harnesses are divided into front wiring harnesses (including meters, engines, headlight assemblies, air conditioners, batteries), rear wiring harnesses (taillight assemblies, license plate lights, trunk lights), roof wiring harnesses (doors, Headlights, audio speakers, etc. Each end of the harness will be marked with numbers and letters to indicate the connection object of the wire. The operator sees the mark correctly connected to the corresponding harness and electrical equipment, which is especially useful when repairing or replacing the harness.
At the same time, the color of the wire harness is divided into a monochrome line and a two-color line. The purpose of the color is also specified, which is usually a custom standard for car manufacturers. China's industry standards only specify the main color, for example, a single black is dedicated to the ground line, and a red color is used for the power line, which cannot be confused. The wire harness is wrapped with a braided wire or plastic tape. For the convenience of safety, processing and maintenance, the braided wire packaging has been eliminated and is now wrapped in tape. Use a connector or wire lug between the harness and the harness, between the harness and the electrical components. The connector is made of plastic and has a plug and socket. The harness and the harness are connected by a plug, and the connection between the harness and the electrical component is connected by a plug or a lug.
