Project 2

Report on Wiring Harness of BackDoor:

Objective:

• Route the Wiring harness on Given BackDoor and Prepare 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.

Electrical Components:

Connectors:

• c-282080-1-d-3d
• c-776438-4-d-3d

Clips/Mountings:

• P Clamp

Design Procedure:

• Get all the required 3D data and convert them into .CATPart files
• Define all the necessary electrical properties of connectors.

Connectors:

• The required geometrical parameters like point, axis on the mating face of the connector are defined.
• Then Define the Connector using define connector command in which we assign the no. of terminals and select the body.
• Define Bundle connection point by selecting representation and initial condition as the normal face and select the midpoint as point.
• Define Connector connection point by selecting mid-point as representation ,mating face ,Coincidence & orientation axis.
• Save the file and the connector is fully defined with all the necessary electrical properties.

c-282080-1-d-3d

C-173090-2

Clips/Mountings:

• The required Geometrical parameters such as Entry, Exit & Base plane is defined.
• Define the Furr tree clip as support part using Define support command by selecting the entry plane as first plane ,entry plane origin as point, exit plane as second plane and base plane.
• Again define the Furr tree clip using define support command by selecting the the exit plane as first plane, exit plane origin as point, second plane is pre-defined as exit plane by system and base plane.

Furr Tree Clip:

BackDoor:

• Create a product file as Assy BackDoor Harness Geometrical Bundle and insert all the connector part file in it and arrange it .
• BackDoor Assembly is used as external reference for positioning the connectors.
• connectors and clips are arranged using the commands manipulation, compass/move, smart move in the assembly workbench.

• Multi-branchable command is used to create main branches.
• Branch point command divides the branch to create the junction.
• And branch definition command used to create the sub branches.
• Apply Protection coverings as required.

Harness Assembly:

• Using Search command in the tools bar, the connectivity of the bundle of BackDoor are checked.
• And all the Bundles are fully connected.

Flattened Assembly:

• Create a new product file and switch to electrical harness flattening.
• Activate the flatness parameters.
• Extract the harness model into the flatness assembly and flatten the bundles using flatten command.
• Adjust the Bundles position & orientation using manipulator, length, synchronise commands.

• After obtaining the flatten product convert the model into 2D drawing.
• Ensure bundles with protective coverings has different visuals on drawing view.

Drafting View Of Harness Assembly:

Conclusion:

• The Wiring harness on Given BackDoor is routed and flattened view of drawing is prepared in CATIA V5. Application of all Packaging rules, Industry best practices studied in this course are demonstrated in the design. Protection coverings are applied as required.
