Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge

DESIGN OF WIRING HARNESS ROUTING IN CATIA-V5

INTROUCTION

The wiring harness routing consists of assembly of geometrical bundle and electrical bundle for the mechanical wiring harness assembly of geometrical bundle is the main component.

For assembly of geometrical buldle the connectors,clip,grommets must br electricaly defined before emtring into the wiring harness assembly.

In the present project the wiring harness for the following mentioned figure.

ASSIGN ELECTRICAL PROPERTIES TO CONNECTORS

The required coonectors are downloaded from te.com. The electrical properties are given to all the connectors using electrical part design.

• Go to electrical part design.
• Defin the connectors by using CONNECTORS.
• Define the CONNECTORS CONNECTION POINT and BUNDLE CONNECTORS POINT to the CONNECTORS.

CREATING WIRING HARNESS

• Create the assembly of geometrical bundle product in CATIA V5.
• Open all the required connectors into the geometrical bundle assenbly product.Note that all the connectors must be electrically defined.
• As mentioned in the figure the connevtors are plased all the required position using the SNAP,SMART MOVE,COORDINATE SYSTEM abd MAINPULATION COMMANDS.
• Now enter into the wiring HARNESS ASSEMBLY workbench.
• Click on MULT-BRANCHABLE DO CUMENT given the branch diameter and the bend ratio open the route defintion and connect the bundle connection point.
• To given the routing from the main branch use ADD BRANCH POINT at the required location and given the sub-branches.
• Now add the corrugated tubes which are creeated and save in the cot-tubes cataloy.
• Cover all the branchs with corrugated tubes given the extremity point from 20mm.

CHECKING BUNDLE CONNECTIVITY

Once the bundle is built, the connectivity of the bundle is to be checked. They should not be any dysconnectivity when copied to another bundle. In order to check the bundled connectivity, go to EDIT, SEARCH, ADVANCE.

CONVERTING ELECTRICAL PART FILE TO MECHANCNIAL PART FILE

Select the Assy_Geometrical _Bundle, go to tools, select the gENERATE CATPART FROM PRODUCT option. The cat part is generated. Now convert the CATpart into igs file, which is the most commonly used file extension for 3D models.
