Cable Harness

What is Cable Harness
A cable and wire harness also referred to as a wire harness, wiring assembly,
cable assembly or wiring loom, is an assembly of electrical cables or wires
which transmit signals or electrical power. The cables are bonded together with
a durable material such as vinyl, rubber, electrical tape, conduit, a weave of
extruded string, or a combination thereof. Commonly used in automobiles, car,
and construction machinery, cable harnesses has several advantages over loose
wires and cables.

Application and environment are the two major factors that determine the types
of the wire harness. Based on these two factors, there are 3 types of harness
cable assembly.

Open Bundle:

The cable and harness assembly is attached to the connectors and lugs and are
coupled in bundles with various breakouts using plastic tie wraps or waxed
lacing twine.

Closed Bundle:

Wires are bundled with a covering, such as pulled-on braided tubing, braided-on
Nomex or nylon, or in some cases, metal braid.

Waterproof Harnesses:

The junctions between the legs and backshells of the connectors are molded with
a material such as urethane or rubber compounds.

Components of Cable Harness
Wire

The role of the wire is to carry current to convey signals and provide power.
It itself contains internal copper wires and external insulating materials.
Commonly used specifications have a nominal cross-sectional area of 0.3, 0.5,
0.85, 1.25, 0.3, 0.5, 0.8, etc. Wires, each of which has a current value that
allows the load, and reasonable use of electrical equipment for different
powers, is the basis for a qualified harness. With the increase of the
functions of automobiles, the widespread use of electronic control technology,
more and more electrical components, more and more wires, the thicker and
heavier the wiring loom harness assembly becomes. In the future, the use of
wires will be reduced, and modern cars have introduced CAN bus configurations
using multiplex systems. Compared with the traditional point-to-point
configuration of the wiring harness, the CAN bus greatly reduces the number of
wires and connectors, making the cable and wire harness lighter and not
limited.

Connector and Terminal

After the terminal and the electric wire assembly are crimped according to the
standard, they are locked in the slot of the connector, and the male and female
connectors are butted to meet the loop between the harness and the harness to
the terminal. If it is arranged in the high humidity environment of the engine
compartment, according to National regulations require that waterproof plugs be
added.

Exterior Parts and Other Components

The exterior parts include a bellows, a polyethylene tube, a polyethylene
cloth, a sheath, a sponge, a tape, a wire fastening harness bracket, etc., in
order to place the wire to wear and break. Meet the temperature and humidity
requirements of different positions of the body. Generally, corrugated pipe,
polyethylene pipe, polyethylene cloth, hard pipe, and sheath are used to
prevent the wire from being worn and broken. The wire is wrapped with thin-
walled and thick-walled tape, and the wire harness is fixed at a suitable
position in the vehicle body by using clips of different shapes. The purpose of
the rubber ring is to prevent the wire cable harness from being scratched when
it passes through the gold hole.
