Wiring harness design in CATIA V5 - 3D modeling Week 4 Challenge
Week 4 Challenge:
Objective: Electrical Harness Routing for the given connectors & application of COT Tubes.
Description:
The elctrical harness routing is explained as below:
- Downloading of specified connectors CAD files from www.te.com
- Define all the connectors electrically using point & axis. Then define connectors elctrically using elctrical part design workbench.
- Create a product naming as Context Assembly.
- Create subassembly as geometrical Bundle Assembly
- Create Subassembly electrical Bundle assembly
- Add the connectors in the Geometrical bundle assembly & create copy of the connectors which will be used more than once & Position the connectors according to the requirements.
- Define the geometrical bundle assembly elctrically by using the geometrical bundle command.
- Create path as per the distance mentioned in the given problem statement.
- Create the part in the context assembly for the path definition using the sketch command.
- Position the connectors on the corners of the path using the compass, manipulation tools & snap, smart move options.
- Create the multi-branchable to define the main trunk. The multi branchable takes us into the harness installation workbench.
- Then after the application of main trunck add the branch point at two positions where branchable definition is required. Then the branchable definition is applied upto all connectors.
- light protection option is used to define the protection on the branchables using the COT tubes using the catalogue defined in the previous exercise. According to the mentioned problem statement the 30 mm end extremity is maintained from the connectors.
C
- The assembly is saved using the save management. After using the save as option I have used the propagate directory option to save the assembly & subassembly in the same file.
- Conclusion:
In this way by using the mechanical assembly workbench, Electrical harness assembly workbench, harness installation workbench the routing is executed & part design, electrical part design is used for elctrically defining the connectors in the above exercise. The Catalogue is used for the COT tubes. By using all these options we can succesfully create the electrical harness routing.
