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. Once the initial design is established, a schematic is used to create the manufacturing paperwork and the assembly board for the harness. The risk of electrical fire is also reduced when the wires are bound within a flame-retardant sleeve.Ī wire harness process is designed based on the geometric and electrical requirements of the equipment it is to be installed in. Space is optimized and the risk of an electrical short is reduced because the wires have been constructed into a non-flexing bundle. Security and safety: When wires and cables are bound within a single harness, the individual components are more secure against the adverse effects of vibrations, abrasions and moisture. The installation then becomes a simple matter of “dropping in” the harness, rather than running all of the wires individually. A wire harness assembly process greatly simplifies the manufacturing of these vehicles by integrating all the wires and cables needed into a single apparatus. Construction machinery, industrial equipment, electronics and white goods (household appliances) will also be constructed using wire harnesses.ĭecreased installation time: Many vehicles require miles of wiring in order to operate. Wire assemblies are most commonly used in the transportation industry, including automobiles, buses, trucks, and planes. The main difference is that a cable assembly normally has only two ends, whereas a wire harness contains multiple breakouts (ends) that run in many different directions with multiple terminations on each breakout. Wire harnesses are often confused with cable assemblies however, the two are quite different. The wire harness simplifies the connection to larger components by integrating the wiring into a single unit for “drop-in” installation. Cables are bound together with straps, cable ties, cable lacing, sleeves, electrical tape, conduit, or a combination thereof. The purpose of the assembly is to transmit signal or electrical power.
