100mm Wire Harness Assembly PVC black ROHS Waterproof Automobile Harness Motorcycle Connection
Wire Special Equipment Wireless
Product information:
A wire harness can be simple, two wires with basic terminals on the
end, or a complex web of many conductors with a variety of
connectors and terminations. In addition, wire harnesses often need
special shapes, sheathing, mechanical fastening and over molded
connectors, grommets or strain reliefs. Our cable can assist in the
custom wire harness design or quote your existing wire and cable
harness design. We’re ready to help solve your cable assembly and
wire harness needs.

Once a design is established, the process of building a wire
harness starts with the development of a schematic that is used to
create the manufacturing paperwork and the assembly board for the
harness. The assembly board, or pin board, is a full size diagram
of the harness and shows all of the components and their location
and also serves as the workbench for the harness. The wires needed
for the harness are supplied on a master reel and are cut to the
desired length and identified with printing or labeling if
necessary. Once cut to the proper length, the wires are stripped to
expose the uninsulated conductor and then fitted with any required
terminals or connector housings. These wires and components then
are put on the pin board and are bound together by any necessary
straps, cable ties, cable lacing, sleeves, tapes, weaves of
extruded string, or any combination of these.
How Metal Becomes Wire
First, the majority of electrical wire is made from aluminum or
copper. After refining the ore, metal is pulled into thick coils
called rod. Rod is processed in large spools and then fed into a series of
dies and rollers which stretch it out into its final thickness, or
“gauge”. To be useful and to be safe, bare wire is covered in a
continuous insulating sheath using various kinds of plastic that
must withstand temperature extremes, solvents, water and UV
exposure. This is performed with a plastic extrusion process not
much different than that used to make plastic bottles.
Only a few kinds of plastic are best suited as insulation since
they must be durable, flexible, accepting of different colored
dies, and not too expensive. Common material includes polyethelene
(PE), polyurethane (PU), rubber and polyvinyl chloride (PVC).
Higher grades of material for better durability and mechanical
strength may include nylon, silicone, FEP, and PTFE (Teflon).
How Wires Become Cables
Usually a single solid metal strand is considered a wire, while
multiple strands or bundles of wire are called a cable. In both
cases, they are conductors for electrical signals. They come in many types and sizes for
power transmission and telecommunication. Telecom cables are often
shielded, using an additional outer mesh of conductor separated
from the inner core by an insulating layer. This secondary mesh is
meant to prevent incidental electromagnetic radiation in the
environment (radio, TV, mobile phone signals) from interfering with
the transmission.
Connectors And Terminals
By themselves, wires and cables can do nothing. They must be
connected to something to perform their function, and that’s where
connectors come in. But what exactly is a connector? Well, a connector actually needs to perform a couple
of functions that can be highly specialized.
Connectors use a metal terminal that is crimped or soldered to a
corresponding conductor, and all of this is placed inside the
plastic shell. Connectors are tasked with making mechanical joints
between male and female terminals, not only holding the whole unit
firmly in place but also protecting it from the outside
environment. Usually the connector can be separated later for
maintenance or replacement, making it an invaluable interface
between the human user and the electrical device. And there are
thousands of types of connectors in every conceivable size and
shape, for every kind of device and purpose.
