Wiring harness design in CATIA V5 - 3D modeling Week 4 Challenge

Routing a Harness Layout in Electrical Workbench :-

1) Defining all the Connectors electrically and add it in Assembly Workbench.

. Download all the given connectors from te.com and unzip it.

. Open any of the Connector mentioned in the given layout in catia's part design workbench.

. Give the geometrical parameters (point, axis ) to it on it's connector connection and bundle connection side.

. switch the workbench to the electrical part design > select ' define connector option '> click on connector.

. A window will pop up> give the no. of terminals accordingly > ok.

. Click on ' define bundle connection point'> click on the connector > a window will pop up.> click on the surface of the bundle connection side for representation > select the point > select the same surface for initial condition > ok.

. click on 'define connector connection point' > click on the connector > a window will appear > select point for the representation > select surface for contact > select y axis for coincidence > select x axis for the orientation > ok. Now the Connector is defined geometrically and Electrically.

. Save the Connector.

. Use the Same Process to define the remaining Connectors and save all of them.

. After that add them one by one in Assembly Workbench.

2) Harness Assembly ;-

. Prepare a 2d layout sketch in part design workbench with given dimensions using different sketch tools (line, point ).

. Switch the workbench to the assembly design with existing sketch.

. Add all the Connectors One by one by using Existing Component Command.

. Now Position that Particular connector close to its place as given layout by using Manipulate option and by selecting respective axis to drag the connector along.

. Place the compass on the connector by drag and drop method> Once the Compass placed on the Connector properly > Click on the Connector > The Compass will turned into green colour > click on the upper green dot of the Compass and hold > move the mouse to Orient the Connector in 360 View > bring the bundle connection side opposite to its position position point on the Sketch. And align its Point as per the given Sketch.

. Now Switch the workbench to Electrical Harness Assembly > Select geometrical Bundle option> Click on product 1, click on Multi Branchable document, a window will appear, give the suitable diameter of the wire and bend-radius ratio , now hide the layout sketch by using tree so that the external curve could be added between the connectors, click on 'line' option, a window will appear , select line type as 'point-point', draw a line between the connectors by Snapping the point on them. The main wire path will form by this, click on empty colum next to the external curve in branch defination , window. click on the path that has been created earlier>ok. The first Multi-Branchable will be form.

. Click on 'add branch point' select the multi-branchable ,place the first point on 100mm distance from the left most Connector>ok.

. Using this method of adding the branch points and constructing the external Curves, the remaining connectors can be connected to the multi-branchable.

. Click On 'add protective Covering, a window will pop up, click on brouse catalouge button, bouses the cot_Tubes catalouge, select it, click on multibranchable, the cot tube will be added on it, double click on 'start extrimity' present at the start of the cot tube , give the clearance value 30mm , ok. Double Click on 'end extrimity' present at the end of the cot tube, give the clearance value 30mm, ok.

. Using this method, the cot tube can be added to remaining multibranchable and the clearance should be only at the connectors.
