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

Objective:

To route harness layout in Electrical workbench.

Process:

Defining the cad files:

• Open the igs files and create a midpoint on the face using point type as between.
  
• Now we can create an axis system to the point we have created by using the command axis system definition.
  
• Make sure the x-axis is pointing towards the locking mechanism of the clip and the y-axis is pointing towards the face of the connector.
  
• We can create a midpoint on the entry using point type as between.
  
• Now we can switch to electric part design.
  
• Select the command bundle connection point.
  
• Enter the number of terminals required.

Harness A:

• Now we can open the electrical harness design workbench.
  
• Select the parent part and copy, and paste all the connectors we have defined.
  
• Now using line command in the assembly design.
  
• We assign the lines in the required dimensions.
  
• After creating the lines we can use the snap command to snap the connectors on the lines.
  
• Now we can select branch definition.
  
• We can select the branch and enter the dimensions.
• Hold on ctrl + f the search tab will be opened.
• Now Select electrical in the workbench.
• Type as bundle segment and attribute as fully connected and select true.
• Now we can see the bundle continuity in harness A.

Harness B:

• Now we can open the electrical harness design workbench.
  
• Select the parent part and copy, and paste all the connectors we have defined.
  
• Now using line command in the assembly design.
  
• We assign the lines in the required dimensions.
  
• After creating the lines we can use the snap command to snap the connectors on the lines.
  
• Now we can select branch definition.
  
• We can select the branch and enter the dimensions.
• Hold on ctrl + f the search tab will be opened.
• Now Select electrical in the workbench.
• Type as bundle segment and attribute as fully connected and select false.
• Now we can see if any bundle continuity fails in harness B.

Routing Harness:

• Now we can route Harness A and Harness B.
• open electrical harness assembly and copy, and paste Harness A and Harness B.
• Now we can open the assembly design workbench.
• Use the Manipulate command to align harness A and harness B.
• Now open the electrical assembly design workbench.
• Select connect electrical devices command.
• Now select connector 5 and connector 6.
• We can see that both the harnesses are now connected electrically.
• Hold on ctrl + f the search tab will be opened.
• Now Select electrical in the workbench.
• Type as bundle segment and attribute as fully connected and select false.
• Now if any bundle continuity fails in the routed harness.
• Open the assembly design workbench and select the annotation command.
• We can name all connectors in order.
• We have named the connectors from 1 to 10.
• Now open tools and select Generate CATpart from the product.
• Now the product will be saved in igs format.

Result:

We have created two harness layouts namely harness A and harness B, using those harness layouts we have routed a harness layout in the Electrical workbench and connected them electrical without any bundle errors and bundle continuity faults. We have also created a igs format of the layout.
