The components of a common wiring harness are: conductors, terminals, and plastic parts.
1. The role of wiring harness
In our electronics industry it means’ electronic wiring harness ‘. Generally refers to a group of low voltage electronic wires. It sets up a bridge of communication between two or more isolated and impassable electronic circuits, so as to enable current circulation and realize the various functions of various electronic components. It is an indispensable part of various electrical appliances and electronic equipment
Complex wiring harness components need to be added: tape, tie, casing, jacket, label, etc.
2. The difference between household wire and ordinary wire
home appliance wiring harness is the main body of the circuit network, there is no home appliance wiring harness there is no home appliance circuit.
Be in at present, no matter be advanced luxury home appliance or economy common home appliance, the form that wire harness plaits is basically same, it is to be composed by wire, link plug-in and wrap adhesive tape.
Home appliance wire also known as low voltage wire, it is not the same as ordinary household wire.Common household wire is copper single – core wire, a certain hardness.And home appliance wire is copper multi core soft wire, some soft wire as fine as hair, several and even dozens of soft copper wire wrapped in plastic insulation tube (PVC), soft and not easy to break.
Electrical appliance wiring harness within the commonly used specifications of the nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 and other square millimeters of wire, they have their respective allowable load current value, with different power electrical equipment with different specifications of the wire.
Simply say single core and multi-core is actually the difference between single and multi-core.Multicore cords are smaller in diameter than single-core cords., the current has skin effect, and the single wire cross-sectional area is equal to the transmission current point capacity is relatively large, calorific value must be greater than the single wire.
Multiple strands are soft and easy to operate, and single core is hard to operate.Single core hard wire, peeling off the insulation is a solid copper wire, the cross-sectional area is generally 1.5mm2, 2.5mm2, 4mm2.About the material why use copper, do not use aluminum, the reason: the internal resistance is large power consumption, the carrying flow is small, the tensile strength is poor, easy to start the oxide layer, the use of short cycle.
So all electrical appliances use multicore wires just like the wiring harness that we use for our cooling fans is multicore wires, like the power cord of a home TV is multicore wires.
