What are Wire Harnesses?

A wire harness is a bundle of wires/cables and terminators/connectors with a protective cover to protect it from tear and wear from harsh environmental conditions and other damaging factors. 

Harnesses are essential because they assist in organizing wires for easier implementation into systems and equipment. Often, people call wire harnesses cable assemblies. 

Some of the benefits wire harnesses offer include:

  • They improve equipment safety.
  • Help optimize space by bundling wires together
  • They are available in a variety of lengths and sizes
  • They provide extended service life on wires and cables
  • They enable customization for special applications

What are Wire Harnesses Used For?

Below are some of the various applications you can use wire harnesses.

  • Industrial and Heavy Equipment: often, you can incorporate wire harnesses into heavy equipment used in construction and various other industries.
  • Automotive: you can use wire harnesses for various purposes like relaying signals, electrical power, and information.
  • Flat panel screens: wire harnesses are used in flat panel screens to organize and reduce electromagnetic interference.
  • Ruggedized computers: you can utilize cable assemblies and wire harnesses in ruggedized computers used in harsh military or industrial environments. The covering helps protect the wires from moisture, dust, dirt and other elements.
  • Flight simulators: to transmit information and energy according to various small space requirements and performance standards, flight simulators utilize wire harnesses.
  • Wire harnesses are also used in medical equipment, electronics, defense and military, construction, and many other fields.

How a Wire Harness Assembler Manufactures Wire Harness?

The wire harness manufacturing process can vary from simple to extremely complex. Below are the steps of the manufacturing process.

  1. Begins with designing and ensuring your harness integrates the custom features for its intended application.
  2. The next step is to cut, strip, and terminate the wire. Strip and cut the wires at your desired length, then attach the metal terminals to the necessary wire ends using a crimp center.
  3. If necessary, insert the wires into your connector housing to enable the female and male wires to mate. You must leave some wires outside your connectors and attach them to the initial equipment.
  4. Lastly, an alternator board bound the wires and cables using an outer covering. The board helps guide correct breakouts and enables final electrical testing.

Despite the introduction of revolutionary machinery to aid in the wire harness process, manual assembly is still dominant. 

This is because routing wires and cables through themselves are very delicate. Manual procedures for wire harness assembly include;

  • Applying tape in different sizes and locations
  • Crimping the terminals to wires which might need numerous crimping operations
  • Inserting sleeves onto each other
  • Fastening the strands of cable ties, tape, or clamps
