Is there any difference between general harness and automobile harness?
The automobile harness standard also has very severe requirements for data: including its electrical function, data dissemination, temperature resistance, etc., which are higher than the general harness requirements, especially those related to safety, such as the harness of important components such as direction control system and brake.
Standard process of automobile harness: the variety of electronic products on the automobile is also increasing, which has become a problem faced by the automobile manufacturing industry. With the continuous improvement of people's requirements for comfort, economy and safety, how to arrange many wire harnesses more effectively and reasonably in the limited automobile space, so as to make the automobile wire harness play a greater role.
Automobile harness standards commonly used standards include wires with nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0 and 6.0 mm2 (the nominal cross-sectional areas commonly used in Japanese vehicles are 0.5, 0.85, 1.25, 2.0, 2.5, 4.0 and 6.0 mm2). They all have allowable load current values and are equipped with wires for electrical equipment with different powers. Taking the whole vehicle harness as an example, the 0.5 standard wire is applicable to exterior lights, indicator lights, door lights, ceiling lights, etc; 0.75 standard line is applicable to license plate lights, front and rear small lights, brake lights, etc; 1.0 standard line is applicable to turn signal lamp, fog lamp, etc; 1.5 the standard line is applicable to headlights, horns, etc; Main power lines such as generator armature line, grounding wire, etc. require 2.5 to 4 mm2 wires. This only means that for ordinary cars, the key depends on the maximum current value of the load. For example, the grounding wire and positive power line of the battery are special automobile wires used alone. Their wire diameters are relatively large, at least more than ten square millimeters. These "Big Mac" wires will not be incorporated into the main harness.
Primary operation: harness, automobile harness, harness processing, wire processing, terminals, cold pressed terminals, harness processing plant, etc.
Automobile harness standard, which is different from ordinary household wires. General household wire harness is copper single core wire with certain hardness. The car harness is made of copper multi core flexible wires. Some flexible wires are as thin as hair. Several or even dozens of flexible copper wires are wrapped in plastic insulating tubes (PVC), which are soft and not easy to break. Due to the particularity of automobile work, the manufacturing process of automobile harness is also more special than other general harnesses.
