USB Harness Assembly 500mm Black HRS Connector Plug-In Car Signal Cable
Product information:
A Wire Harness, also known as a cable harness or wiring assembly,
is a grouping of wires, cables, or subassemblies designed to
transmit signals or electrical power. A basic Wire Harness may
include as few as three discreet components, while the more classic
harnesses include many more wires and other passive, and
potentially active, components.

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.
Making Overmolding For Wires and Circuit Boards
Some complicated assemblies combine printed circuit boards soldered
to fine wires. These need to be sealed in a plastic housing to
protect them, but how to do this without destroying the delicate
electronics?
Overmolding uses low-melting-temperature plastic that’s slowly
pressed over the entire assembly and then cooled, which makes a
single solid block which seals and protects it. In this regard the
overmolding process is a hybrid combination of die casting and
plastic injection molding. This is a one-time process; the
connector can never be opened again without destroying it, but it’s
robust and reliable if done right.
