If you have a vehicle project that requires a custom wiring harness, call the team at Kinkong customization harnesses. For example, rather than individually installing each wire, cable, and subassembly, the saddle consolidates them into a single unit for the OEM or installer to handle. Caption: Multicolor wires packed in automotive. Once a design is finalized, the first step in making a wire harness is drawing out a schematic that will be necessary for documentation and assembly board. As a result, the wires will be safe from any potential electrical damage, whether inside or outside. Another mistake that engineers make is lack of standardization in the design criterion. Pre-design measurements should include: Wire ends which includes strip lengths, type of terminal, coating of terminal and end, connection points, connector design. Others will face pressure. PCBs and custom cable harness assemblies. If you dont have a standard and would like to develop one, a good place to start is to review the IPC/WHMA-A-620; this could serve as a set of generic standards that can be modified to suit your needs. Cable considerations Richard Antic of cable manufacturer Champlain Cable points out one of the primary considerations for an EV cable system: the heat it must withstand over the expected life of the electrical system. It uses a controlled and streamlined, correct-by-design process to provide digital continuity across domains. The design of the wiring harness is based on many factors. However, you can also use a wire cutter for this purpose. The wiring harness is designed once the schematics are ready. Will vibration affect cable contact points in final install? First, you may develop a harness design in a particular space, which is what the method attempts to find. Some of the aspects that need to be considered when it comes to wire harness design so that it functions safely and as per specifications include: Environmental considerations; Power Demand; Lengths; Taking these details into account at the design stage means that costly errors can be avoided later & that the results are more effective. So now lets see the basic process for executing a wire harness diagram. Low cost parts can often have high associated assembly costs. How are the components delivered from the suppliers (bulk, discrete, other) and how will you receive and inspect them?
