Project 2

Backdoor Wiring Harness Using-CATIA-V5:

Aim:

• To Route the wiring harness on given BackDoor.
• To Prepare the Flattened View of wiring harness.
• To prepare the Drawing sheet.

Given Data:

Wiring Harness Routing Methodology:

• I have Made an assembly with the given Part.(BackDoor)
• The BackDoor Assembly Consist of

1.Inner Pannel 2.Outer Pannel Upper And 3.Outer Pannel Lower.

Whole Assembly:

• The backdoor Has different types of electrical harness. they are

1. Rear Windshield Wiper Motor.
2. Right And Left Tail Lights.
3. Number Plate Lights.
4. Trunk Lights.(Helps In access of Trunk in Dark Areas)
5. Rear Windshield Defrosting Heating Coil.(Paralllel Line Present in rear Windshield)

• Rear Windshield Wiper Motor Connector.

• Right And Left Tail Light Connectors.

• Number Plate Light Connector.

• Trunk Lights.(Helps In access of Trunk in Dark Areas)

• Rear Windshield Defrosting Heating Coil.(Paralllel Line Present in rear Windshield)

• Inserting and Positioning the Clips and clamps to route the bundle.

• Rubber grommet to route the bundle outside the assembly.

(in actual environment It is Look like)

Creating a Multi-branchable:

• Inserting Corrugated Tubes and Cotton tapes to Harness Bundle.

• Checking the Bundle Segment if it is Fully connected=False.

• Checking the Bundle Segment if it is Fully connected=True.

Flattening Methodology:

• Create a new product named Wiring Harness Flattening_TailGate.
• Switch the workbench to Flattening Workbench.
• Define the parameters.
• Then Sideloading the Wiring harness Assy-Tail Gate.
• In Electrical Harness Assembly- Inserting the wiring harness assembly by Extract Command And Required Face.
• Then Flatten The Assembly By Flatten Command and Selecting the Required Face & Required Branches.

Flattening Parameters:

Flattened Part:

• Then Bend the Harness By Roll Command.

• Rotate The Branch By Using Rotate Command

• Then if a branch needs to Increase in length for Appearance It Can be fake scaled by using the Scale Command

• Using the Compass to Manipulate the Connectors, Mounting Equipment & Clamps To Position it.
• By using synchronize Command Can be link and unlink with main assembly.

Drafting Methodology:

• Creating a new Drawing File.

• Importing the front view of Flattening Assembly.
• Changing the properties of the view.

• To fit the Assembly in Drawing sheet I have scaled it to 1:2 Ratio.
• To differentiate the Cot Tubes and Bundle I have shown the 3D Wireframe is always visible.

• Then Switching to sheet backround to create a Frame & title block.

• Switching Back to working view to generate Balloons.

• Then Generating Bill Of Material.
