When designing a new product, engineers focus mainly on functionality, features, styling and cost. The wires are bound by a durable material such as nylon tie in the assembly process. Houston, TX 77034. But, as new convenience options have been added, such as automatic tail gates and lane-departure warning systems, they have required additional ECUs, says Lydon. For instance, fires routed close to the exhaust and engine are subjected to tremendous heat. So to avoid them, keep reading and find out what could go wrong. Your referral is top notch. Too little information, on the other hand, makes the harness drawing raise lots of questions or inconsistent final products. While a harness design may look good on the drawing board, it might not be practical or even feasible when it comes to actually installing it inside a vehicle. Certain businesses require flexible wire harnesses. JIANSHAN RD, The conditions the harness will be exposed to as a result of how it is routed must be taken into account. You will learn how to design parts and assemblies and create simple drawings. Out of the multiple number of factors to be considered for the designing of cable harnesses, environmental factors are the most important ones. This course will introduce you to the fundamental concepts of CATIA V5. The harness must fit neatly in its intended space. Mistake 2 Failure to control and translate the analytical, functional, and commercial requirements of the harness into connected product lifecycle management methodologies and workflows.

How will materials be received, inspected, rejected (if necessary)? However, with the proper knowledge and expertise, you can make wiring harnesses by hand. Is the process of wire cutting performed so the cut ends are uniform and all strands are the same length? Voltage/current requirements ( types of wire, sizes of conductors) Does the harness design have an appropriate grounding scheme? Has mistake-proofing been implemented for cable with more than two same connectors different color, different type? The designing and drawing of a wiring harness are the basics of the entire process. Difference between Single-core and Multicore Cable, Wire and Cable Manufacturing Capabilities, Considerations When Drawing a Wire Harness, Wire Harness and Cable Assembly Prototype Design, Requirements and Acceptance for Cable and Wire Assemblies, No.37 street 3, xifang, Daning Community, Humen Town, Dongguan City, Guangdong Province,China. So the wiring harness doesnt perform as expected in certain circumstances. In fact, engineers need to put their thoughts into the various elements of wiring like wire length, bending radius, and routing. Each of these processes is now carried out mechanically. How to route in final application for service and product life? Wiring harness problems typically manifest in three ways. This cookie is set by GDPR Cookie Consent plugin. In the past, wire harness design was done on the fly during assembly. Standardization of the work and data flow is crucial to avoiding costly mistakes.. A wire harness that is properly designed will not malfunction or require replacement. Some harnesses will be heated. Length and tolerance of wire (must be long enough for the bend radius, should also reach the connector) and ability of wire to stand up over time. Also, remember the success of an electric wire harness design will only depend on the wiring harness diagram. Protecting from EMI will pose significant challenges to implementation. For design reference, a few of the common geometry's for subcabled and intersticed constructions are shown. Roach suggests carefully considering the physical environment. If you have an internal harness specification or guidelines for the production of your equipments wiring, your outsourcing partner will need to have that on hand in order to develop the right solution.

The diameter of the large mem- If you use your own part numbers on your drawings, make sure you provide a way for your outsourcing partner to be able to cross reference them back to a manufacturer and a manufacturer part number. If a certain part does not necessarily need a specific brand, its imperative to note or equivalent on the drawing part list. This allows for easier application on the harness, but zip ties or tape are then required to secure the protection to the wire harness, which will allow liquids to flow through. One of the worst mistakes [people make] is cutting the wires too short, as this tends to scrap the whole harness, says Jon Collins, business development director at design software firm Cadonix Ltd. Another common mistake is not carrying through the initial design intent as far as the connectivity definition is concerned. However, one of the biggest determining factors is the environment in which the harness will be applied. Mistake 1 Cutting the wires too short that tends to scrap the entire cable harness.
