WIRING HARNESS DESIGN PROJECT 1

AIM:

Design and develop the Wiring harness on Given V6 Engine and Prepare flatten view drawing in CATIA V5. Application of all Packaging rules, Industry best practices studied in this course shall be demonstrated in design.

INTRODUCTION:

A wire harness, also mmonly referred to as a wiring harness, is an exterior sheath used to cover some types of electronic wires. Generally, wiring harnesses are made of thermoplastic or thermoset materials that can help protect the cables from the environment.

OBJECTIVE:

• Define all the mechanical connectors electrically and save it in the Catalogue.
• Place all the connectors to the required positions on the given engine 3D CAD model
• Place P-Clamps and Fir Tree clips at the required position by following the packaging rules.
• Create the Wiring Harness Routing with all the electrically defined connectors and mounting equipments.
• Create branching points at required locations to create sub branches and connect to various connectors in the geometrical bundle.
• Apply Protection coverings as required.
• Create Wiring harness flattening for the final geometrical bundle.
• Using the drafting workbench, create a drawing sheet with the flattened wiring harness.

Creating the context assembly:

Use of Corrugated tubes

• They are of two types Slit and Non-slit Cot tubes
• Corrugated flexible tubes also known as COT tubes / convoluted conduits have a wide range of applications in automotive industries.
• Corrugated tubes are made from plastic and they are flexible.

Conclusion:

In this project i have successfully routed the wiring harness for the Engine assembly and the flatten-view drawing was prepared in CATIA V5. Various packaging rules and constraints were considered while routing the harness.
