As part of our Spring Blog Series, InterConnect Wiring is highlighting the best blogs that our readers loved the most in the past five years. Say hello to our top blog from 2017: What is a wiring harness?
To put it simply, a wiring harness is a group of wires bundled together. A wiring harness can be very small in size such as a small group of wires found in your computer or car. A wiring harness can also be very huge such as some of the ones that InterConnect manufactures for aircraft. These huge wiring harnesses may have thousands of wires in them and hundreds of connectors. The finished wiring harness may weigh over 100 pounds and cost over $50,000.
When I meet people and they ask what a wiring harness is, I give them the example of an extension cord. When you buy an extension cord you are buying a small wiring harness. Wiring harnesses have many different names including: electrical wiring harnesses, looms, cable assemblies, coax cables, RF cables, injection molded cable assemblies, fiber optic cables, and many times are simply called harnesses.
Wiring harnesses are important for aircraft because they can be installed as one unit instead of one wire at a time. It is much easier to build them on a table in a production area such as InterConnect Wiring’s production area as opposed to putting in wires one at a time in an aircraft and then connecting each wire to a connector or terminal or a splice. It is much easier and faster to route a group of wires already bundled together than routing them individually.
