Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge

Wiring harness routing

Aim:

To convert a mechanical convert and backshell into electrical part and wiring harness routing for given diagram.

Objective:

· Create an bundle entry, connector connecting point and define connector in electrical part workbench.

· Positioning the connector by using various methods.

· Create a bundle with required dimensions and check connectivity.

Introduction:

In wiring harness design connectors need to be convert into electrical part for connecting cavity and harness bundle. Connectors are plastic molded parts having with locking and retention features. Protection coverings are flexible, temperature, wear and tear resistant molded plastic. A wire harness is a specially designed system that keeps numerous wires or cables organized. It is a systematic and integrated arrangement of cables within an insulating material. The purpose of the wiring assembly is to transmit a signal or electrical power.

Bundle warning:

Remedies:

· First check whether the bundle is connected with proper tangent, if it’s not reverse the tangent.

· If the computed bend radius is below the required radius, it’ll show warning then we need to move connector or provide slack to the bundle.

· If the slack is high but the distance of the connector and branch point is low then it’ll show bundle warning, then we need to reduce slack or re-positioning the connector.
