Wiring harness design in CATIA V5 - 3D modeling Week 2 Challenge

AIM:

Download following connectors & Connector clip cad data from given link & define it as Electrical Connector using Electrical Part design Workbench. Define all the necessary properties to Connectors & Clip.

Important workbenches in CATIA V5.

the important workbenches that are required for the mechanical wiring harness routing.

Definitions of electrical workbenches in CATIA V5.

shows the feature tree that has to be followed while developing the wiring harness routing.

shows the changes that has to be made in cache management. In working with large amount of data in order not to lose any data and open the workbenches quickly, work with cache system option is toggled on. The information from other departments can be easily open when this option in activated.

Changes to be made in cache management.

The catalog is a part storing document in which the parts which are frequently used in the modelling are stored and retrieved whenever it is required and at any location.

Changes to be made in catalog editor.

To create a new catalog, Go to New, select the catalog document. In catalog document create a family by using the add family option from Insert.

To create catalog in catia.

ELECTRICAL PART DESIGN

Command overview

Command overview of wiring harness routing.

shows the different electrical harness routing commands that are available in the electrical part design workbench.

Connector definition.

shows the Connector definition and the detailed process. Fig 16 shows the different connector parts.

Connector parts.

Geometry Parameters – Points and co-ordinate system (axis).

Connector connection points – This point is used for the connection of one connector to another connector.

Harness bundle entry point – This point defines where the harness bundle segment point will end when routed to the electrical connector.

Cavity connection point (optional): This point is used to define the connection of a connector to a connector clip. This only applies to connectors which have the mounting feature for a connector clip.

Connector axis system definition.

Once the bundle and connector entry points and axis system are created in part design workbench as shown in Fig. 17, switch to electrical part design workbench. In electrical part design workbench click on Define Connector option and click the connector and enter the type, name and number of terminations.

Connector Definition.

Change the termination names as 1,2,3,4 as given in the part.

Termination name changed to 1,2,3,4.

Now give the bundle connection point definition by clicking Define Bundle Connection and give the details as given in Fig. 20.
