Project 2

BACK DOOR WIRING HARNESS ROUTING

AIM: Route the Wiring harness on Given car body 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. Apply Protection coverings as required.

PACKAGING RULES AND ASSUMPTIONS:

• Provide Enough Clearance to the wiring harness with respect to the surrounding
• Avoid harness routing and clipping in blind zone
• Provide additional slack to the harness according to the surrounding. 5-10% of slack
• Branch length should maintain with 50mm
• Minimum distance between clip and nearest branching point should be 25mm
• Minimum distance two breakouts should 50mm

WORKING PROCEDURES:

STEP 1: Download 3d Model from given Website

STEP 2:

• Download all Connectors from Website and Defined ElectricallyAby Geometrical Sets
• Points and Axis Sytems are used to defining the Connectors
• Defining 3 Pole connector by Electrical Part Design workbench
• Defenition of 2 Pole Connector
• Definition of Inter connection Point it have 12 termination
• Fir tree clip above shown, these clip defined by support part definition. It has 2 bundle entry Points and one Base Point

STEP 3:

• BACK DOOR WIRING HARNESS CONNECTORS AND CLIPS PLACEMENTS

STEP 4:

• Routing start with Inter Connection Connection Point to the Fir Tree Clip
• Click on Geometrical budle command by convert to Electrical assembly
• After Converted Start Routing with Connectors
• Click Multibranchable to give diameter of bundle 10mm
• Bundle bend radius must have 1.5 times greater than bundle Dia
• Slack is given additional for avoiding clashes or anyother errors

• Same Routing Procedure are followed by All bundle Connection

STEP 5:

• CoT Tube Creation and add to Catalogue for bundle creation assembly

STEP 6:

• Geometrical Assy Extraction to Flattening Assembly
• Before Extraction to Switching the Flattening assembly & set flattening parameters
• After Extraction to flatten the bundle segments by using flatten command

STEP 7:

• ELECTRICAL HARNESS FLATTENING

STEP 8:

• ELECTRICAL HARNESS FLATTENING DRAWING

CONCLUSION:

• Back Door Wiring Harness Assembly Created by using CATIA V6
• After Completed this model. It has been verified or tested by Electrical Engineers. If this model Ok continue to Manufacturing Department
