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

Q1. Route the following harness layout in the Electrical workbench. Make assumptions for harness bundle diameters. Use the connectors provided after the completion of routing.

INTRODUCTION

The wiring harness routing consists of an assembly of the geometrical bundle and an electrical bundle. For the mechanical wiring harness, the assembly of the geometrical bundle is the main component.

For assembly of the geometrical bundle, the connectors, clips, and grommets must be electrically defined before entering into the WIRING HARNESS ASSEMBLY.

In the present project, the wiring harness for the following mentioned figure

ASSIGN ELECTRICAL PROPERTIES TO CONNECTORS

The required connectors are downloaded from te.com. The electrical properties are given to all the connectors using electrical part design.

1) Go to electrical part design.

2) Define the connectors by using the CONNECTORS command.

3) Define the CONNECTORS CONNECTION POINT and BUNDLE CONNECTORS POINT to the CONNECTORS.

CREATING WIRING HARNESS

1) Create the assembly of a geometrical bundle product in CATIA V5.

2) Open all the required connectors into the geometrical bundle assembly product. Note that all the connectors must be electrically defined.

3) As mentioned in the figure, the connectors are placed al the required positions using the SNAP, SMART MOVE, COORDINATE SYSTEM, and MANIPULATION COMMANDS.

4) Now enter into the WIRING HARNESS ASSEMBLY workbench.

5) Click on the MULTI-BRANCHABLE DOCUMENT, and give the branch diameter and the bend ratio. Open the route definition and connect the bundle connection points.

6) To give the routing from the main branch use ADD BRANCH POINT at the required location and give the sub-branches.
