What are Wire Harness and Cable Harness?

  • Cable harness is bound together with straps, cable ties, cable lacing, sleeves, electrical tape, conduit, or a combination thereof.

  • Wire harness contains multiple breakouts that run in many different directions with multiple terminations on each breakout

 
Wire harness simplifies the connection to larger components by integrating the wiring into a single unit for drop-in installation. It looks easy but not really. The wire harness assembly has been our core business since 2000. Avertronics designs and manufactures the high quality and reliable wire harness products for the automotive industry, engineering industry, healthcare industry, renewable power generator and light e-mobility industry .
 
A good wire harness can transmit all of power and information to automotive microcontroller. It likes human’s circulatory and nervous systems. A wire harness process is designed based on the geometric and electrical requirements of the equipment it is to be installed in. Once the initial design is established, a schematic is used to create the manufacturing paperwork and the assembly board for the harness. The assembly board, also called a pin board, is a full-size diagram of the harness which shows all of the components and their locations. It also serves as the workbench for the harness. Therefore, the experience is very important. Avertronics has been experiencing it for decades.
Wire harness assembly needs experienced engineers for cutting the wires to the desired length and labeled appropriately. Then, they  strip the ends of the wires to expose the un-insulated conductor and fit with required terminals or connector housings. The wires and components are then assembled on the pin-board to the desired specification and then bound together. When wire harness assembly process, it is more efficiently done by hand than automation. 
In process, engineer is still to inspect the harness for splice connection and crimp quality (please refer to https://www.avertronics.com/en/news/index.php?sysUserId=99 & https://www.avertronics.com/en/news/index.php?sysUserId=100 ). This inspections are to make sure comprehension connection pin to pin. Final testing is to make sure per desired electrical functionality. It is done with a pre-programmed test board. The test board is programmed with the required electrical characteristics and the completed harness is then plugged into the board and checked for faults.
