Project 2

Objective:

Statement of assignment:

Route the Wiring harness on the given car body and prepare a flattened 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.

Available connector 3D data can be used, or you can download the connectors from www.te.com

Prepare & Submit all necessary reports like clearance, Clipping/Clamping selection, Harness fixing requirements, Harness continuity, and Assumptions if any along with CATIA 3D data.

Procedure:

Give the Electrical properties to the connectors, and clip.

Connector 1:

Create a point on the mating surface and a point at the back as the bundle entry point. Create an axis on the point.

Connector 2:

Create a point on the mating surface and a point at the back as the bundle entry point. Create an axis on the point.

Connector 3:

Create a point on the mating surface and a point at the back as the bundle entry point. Create an axis on the point.

Furr Tree Clip:

Create 2 points on the top surface.

Deciding the routing path and clip position by observing the Back Door:

Start to align the clips:

Insert the connectors and align them:

1 interconnection connector.

2 tail light connectors.

1 window wiper connector.

1 power lock/latch connector.

1 tailgate button connector.

Start routing the bundle segments:

Create branch.

The bend ratio is 1.4.

Slack of 1 - 5% is provided at the necessary location.

Create branch points where ever necessary.

Continue the branch and connect to the remaining connectors.

Checking the connections:

Apply protective covering to the bundle segments:

Keep the extremities 10 mm or 5mm away from the connectors.

Flattening the Harness Assembly:

Create a new product and go into the "Electrical Harness Flattening" Workbench.

Click on the "Harness Flattening Parameters" option to adjust the parameters.

Use the "Flatten" option to flatten the assembly.

Select a plane/flat surface or a connector and all the branches.

Rotate the bundle segments and align the clips accordingly. Use the Manipulation, Smart Move, and Roll options to align.

Create a 'Drawing' file and add the harness assembly to the drawing.

Conclusion:

All the necessary properties are applied to the connectors, clip, p clamp, and channel.

Provided proper routing of the bundle with support parts like clips and clamps.

Added protective covering to the bundles.

Flattened the harness assembly completely. Placed the flattened view on the drawing sheet.
