Mobile WebSiteWhat are the wire specifications for automotive wiring harnesses?
Wire harnesses commonly used in automobiles have a nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, etc., each of which has a permissible load current value and a different power electrical equipment wire . In the vehicle wiring harness, for example, the 0.5 meter rail line is applied to the lights, lamps, light doors, ceilings, etc .; the 0.75 specification applies to license plate lights, front and rear small lights, brake lights, etc .; the 1.0 specification line is suitable for turn signals, Fog lights; suitable for headlamp wires, speakers, etc. 1.5 specifications; main power wires such as generator armature, ground wire requirements from 2.5 to 4 mm2 wires.
This means that for ordinary cars, the key is to see the maximum current value of the load. For example, the battery ground and positive power cables are used separately. Their wire diameters are relatively large, at least more than 10 square millimeters. These "Big Mac" wires will not be included in the main harness.
The automobile wiring harness is the main body of the automobile circuit, and there is no automobile circuit in the wiring harness. Automotive wiring harness refers to the components used to bundle and form the connection circuit after the contact terminals (connectors) made of copper material are pressed into contact with the wires and cables, and then plastic pressed insulators or external metal shells are used outside the wiring harness. The electronic wiring harness industry chain includes wire and cable, connectors, processing equipment, wiring harness manufacturing and downstream application industries. Wiring harnesses are widely used in automobiles, home appliances, computers and communication equipment, various electronic instruments, etc., automotive wiring harnesses are connected to the vehicle. The general shape is H-shaped.
