Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge

Aim

To Flatten the harness assembly and place the flattened view on drawing sheet. By bundles with protective coverings has different visuals on drawing view.

Procedure

Step 1: Define the Mechanical Connectors Electrically.

• Creation of connector connection point and Connector Connection Axis

• Make a midpoint on the contact face for wire bundle insertion.
• Create an axis system referencing the newly generated point and specifying the axis direction.
• The Y-Axis should be oriented towards the connector's front face.
• The X-Axis should be oriented towards the clip's locking mechanism.
• The Z-axis should be pointing across the connector from left to right.

• Creation of Bundle Connection Point.
• Define the part as a connector
• Define connector connection point.
• Define Bundle connection point.

Step 2: Arranging the Connectors & Creating Multi-Branching to the connectors as per the design.

Branches diameters are 10mm and 5mm

Step 3 : Creation of Protective covering.

Create the protective covering with Cot tubes of 10mm and 15mm

Step 3 : Harness Flattening

• Define the "Flattening Parameters" in harness flattening Workbench.
• Extract the Harness assembly to the Harness Flattening Workbench.
• The patrs are assembled in a proper way that they are easily visible.

Commands for Modifications,

• Straighten : To straighten the Bundle
• Rotate : To rotate the bundles.
• Bend : To bend the Bundles. Similar to rotate, but radius is applied to the bundles.
• Quick rool : To roll the bundles with nearest point reference.
• Arrange Junction- equal angle : To provide same angle from Junction point.
• Scale : Scalling for bundles to adjust drawing view. (Fake scaling)
• Auto Update Flatten link / Remove Flatten Link / Manually update
• Synchronize

Step 3 : Harness Drawing

Conclusion

Thus the Wiring Harness Assembly is created in Drawing sheet Workbench by Flattening the harness assembly using Catia V5.
