Wire Harness Design Concerns

6 Biggest Concerns for Wire Harness Experts

Wire harness assemblies are an essential component in many electronic products and equipment, and the design process for these assemblies must take into account several important concerns to ensure that the final product is reliable and meets all necessary requirements.

Proper Routing & Organization

One of the biggest design concerns for wire harness assemblies is ensuring proper routing and organization of the wires and cables. The harness must have the wires and cables properly routed and arranged to prevent any damage, wear, and tear and also to prevent any interference between the different wires. The routing also has to take into consideration the physical constraints of the application and avoid any possible stress points or areas that may cause damage over time.

Material & Connector Selection

Another concern is selecting the correct materials for the wires and cables. The materials must be suitable for the intended application and environment and must be able to withstand the conditions to which the harness will be exposed. This includes factors such as temperature, humidity, mechanical stress, and exposure to chemicals or other environmental factors.

A related concern is the connector selection, which is an important part of wire harness design. The connectors must be compatible with the wires and cables and must meet the requirements of the specific application, including factors such as temperature, humidity, and vibration. It is also important to choose connectors that are easy to install and maintain, to minimize downtime and maintenance costs.

Labeling, Marking, Tracing…Oh My!

Another important design concern is the use of proper labeling, markers, and traceability codes. The harness must be clearly labeled to allow for easy identification of each wire and its corresponding connector, as well as traceability codes, to be able to identify where each part of the harness comes from and when it was produced. Proper labeling is also critical for maintaining compliance with industry regulations and standards.

Durable Design

Designing a wire harness assembly that can withstand the rigors of production, transportation, and the intended application is also a significant concern. This includes things like ensuring that the harness is durable and resistant to wear and tear and that the wires and cables are properly secure to prevent them from becoming loose or disconnected.

Test the Limits

Additionally, proper testing and validation are key concerns, to ensure that the wire harness assembly meets the specifications and requirements of the application. The harness assembly must ensure that all the connections are secure, that there are no open or short circuits, and that all the wire connections are proper.

What’s the Cost?

Finally, the cost is always a concern when designing a wire harness assembly. The cost of materials and components can add up quickly, and it’s important to minimize costs by using the most cost-effective materials and components.
