Project 2
Wiring harness Of Car Back Door
1. Wiring Harness routed in such way that it is easy to assemble and access.
2. Easy manufacturing, installation, removal and maintenance have to be considered while designing the wiring harness.
3. Wiring Harness should be kept away from sharp environment like edges, corners etc.
4. Provide additional slack if neededAs per the harness bending requirement.
5. Avoid Routing through the Smaal Holes and opening.
6. It should be Make sure that there is no case of fouling while designing the wiring harness
7. Add mounting equipments like clips/clamps may be used to avoid fouling.
8. The branch length should be greater than 50mm.
9. The minimum distance between the clip and branch point should be at least 25mm.
10. The minimum distance between the two branch points should be at least 50mm.
11. The bend ratio for all the bundle segment is considered to be 1.4 or grater.
Used Equipments
one C-446738-4-d Connector Type For Interconnection
Four 2-pole COnnectors are used for back lights,Indicators and wiper
Sticky clamps and Fie Tree Clips are used for the flow of Bundle Segment systematically

Open it in CATIA-V5 Start Defining the part
Define the Geometry Parameters in Part Design
1. Points and axis system are defined in Part design Workbench
2. Points are defined at Connector connecting and Bundle entry Surfaces of connectors
2. Axis system is defined at Connector connecting Point
Then Switch to Electrical part design work bench to define it as a connector and the
electrical properties of of the Connectors like connector connection point and Bundle connection point
After this process
Switch to Electric Harness Assembly
1. Add New Product Rename it as a Harness Context Assembly
2. Add all these connectors in One bundle Rename it as Geometrical Bundle which is a sub level Product file
3. Arrange all these connectors as per the given layout with the dimensions
4. Add Multi-Branchable Document in Geometrical Bundle Tree to create Bundle between the Connectors and
5. Add Protecting Coverings with COT TUBES Keeping End Extremity 20mm from the connector
Harness Flattening:
Switch to HARNESS FLATTENING WORKBENCH AND DEFINE THE FLATTENING PARAMETERS.
We use the Extract command to bring the Harness assembly to the Flattening workbench
Add Suitable the Plane and start flattening the Harness Assembly by Selecting all the Bundles
Rotate the Bundle at the requied Angles.
Drawing and Drafting
Switch to new drawing and start drafting
Select front View add the Flattening product to drawing file
Flattening Parameters are defined in order to make
Bundle with single line and corrugated Tubes in 3d drawing
Add ballon to every Connectors and Corrugated tubes
Make a table name the connectors
