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

REPORT

First step is to download the Connector CAD files from the source.

Next define each connector by creating connector connection and bundle connection point.

For that, Open the connector cad part

At first a point has been created on the mounting side of connector. Next Create an Axis system by taking the created point as origin.

While Creating axis system few rules are to be followed on the setting of the orientation of axis.

X-Axis should be towards the locking mechanism.

Y-Axis should be towards mounting direction.

After that we need to define the cavity connection point. On the connector a locking feature is been provided. Create a point on the edge of locking feature. Now create an axis system by taking the created point as origin. Orientation of axis on the axis system should be followed as same as done in mounting side.

Now Switch to Electrical Part Design

Define the connector by Define connector option. Provide type as Single Insert Connector and provide the number of terminations. Now select Bundle connection point option and define the bundle connection point. Select face as representation and on initial condition select the same face.

Now select Connector connection point for creating the connection point. Click on connector, Select the point created on connection point as representation and on contact select the face on which point created. Coincidence select X-Axis and orientation select Y-Axis.

Follow the same steps for other connector also.

For that we need to assemble all electrically define connectors.

First create a Product file by FileàNewàProduct.

Now add new product by right click on productàcomponentsànew product. In that right click and select existing components under component and add the file. After that define it as geometric bundle. Now by manipulation and snap tools making proper orientations on connector as needed.

After that click on Multi Branch-able Document option and Give diameter and bend ratio as 1.4 then click on Route definition and select the connectors click on ok. These steps are followed for other connectors.

Same is done to second routing also

HARNESS A

HARNESS B

Next is to assemble these two created routing

For that click on FileàNewàProduct

After that right click on product and select existing component option and add two routings.

Now by manipulation and snap tools orient the assemble as required. After that connect the required two connectors for that switch to Electrical Harness Assembly and click on connect electrical device option and connect two required connectors.

Next step is to check bundle connectivity for that click on editàsearch

Under advanced tab on workbench select Electrical, on type bundle segment and on attribute select fully connected. Make attribute criterion as true. Then click on search icon.

Next step is creation of annotation switch to assembly design

Click on insertàAnnotationsàTextà Text Parallel to screen

Click on connector and name it

Repeat these same steps for all connectors
