- Common specifications of the wires in the car harness have a
nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0,
6.0 square millimeters of wire (Japanese cars commonly used in the
nominal cross-sectional area of 0.5, 0.85, 1.25, 2.0, 2.5, 4.0, 6.0
square millimeters), they each have allowable load current values,
with different power Wires for electrical equipment. Take the whole
car wiring harness for example, 0.5 specification wire for
instrument lights, indicators, door lights, dome lights, etc.; 0.75
specification wire for license plate lights, front and rear lights,
brake lights, etc.; 1.0 specification wire for turn signals, fog
lights, etc.; 1.5 specification wire for headlights, horns, etc.;
main power lines such as generator armature wire, override wire,
etc. require 2.5 to 4 square millimeter wire. This refers only to
the general car, the key to the maximum current value of the load,
for example, the battery hitch line, the positive power line is a
special car wire used separately, their wire diameter are
relatively large, at least a dozen square millimeters or more,
these "giant" wire will not be woven into the main harness.
- In modern automobiles, automotive wiring harnesses in particular,
electronic control systems and wiring harnesses have a close
relationship. Someone once played an image metaphor: If the
microcomputer, sensors and the function of the executive components
with the human body to compare, it can be said that the
microcomputer equivalent to the human brain, sensors equivalent to
the sense organs, the executive components equivalent to the organs
of movement, then the wiring harness is the nerve and blood
vessels.
- Automotive wiring harness is the main body of the network of
automotive circuits, connecting the electrical and electronic
components of the car and making them function, without the wiring
harness there would be no automotive circuit. At present,
regardless of whether it is a senior luxury car or an economical
car, the wiring harness is basically the same in form, and is
composed of wires, connectors and wrapping tape, which not only
ensures the transmission of electrical signals, but also ensures
the reliability of the connected circuits, supplies the specified
current value to the electrical and electronic components, prevents
electromagnetic interference to the surrounding circuits, and
excludes electrical short circuits.
- From a functional point of view, there are two types of automotive
wiring harnesses: power lines that carry the power of the actuators
and signal lines that carry the input commands of the sensors.
Power lines are thick wires that carry large currents, while signal
lines are thin wires that do not carry electricity (optical fiber
communication); for example, the cross-sectional area of wires used
in signal circuits is 0.3, 0.5 mm2.
- In the motor, executive components with wire cross-sectional area
of 0.85, 1.25mm2, while the power circuit with wire cross-sectional
area of 2, 3, 5mm2; and special circuits (starter, alternator,
engine ground wire, etc.) are 8, 10, 15, 20mm2 different
specifications. The larger the cross-sectional area of the
conductor, the greater the current capacity. The choice of wire, in
addition to the consideration of electrical performance, but also
by the physical properties of the car when the constraints, so its
choice of a wide range. For example, the wire between the
frequently opened/closed doors and across the body of a rental car
should be composed of wire with good flexural properties. Wires
used in areas with high temperatures are generally made of vinyl
chloride and polyethylene covered wires with good insulation and
heat resistance. In recent years, the use of electromagnetic
shielding wires for weak signal circuits has also increased.
- With the increase in the functions of the car, the widespread
application of electronic control technology, more and more
electrical parts, wires will also be more and more, the number of
circuits on the car and the power consumption increased
significantly, the wiring harness also becomes thicker and heavier.
This is a big problem that needs to be solved, how to make a large
number of wire harnesses in the limited space of the car how to
more effectively and reasonably arranged, so that the car wiring
harness to play a greater function, has become a problem facing the
automotive manufacturing industry.
