OBJECTIVES :

• Defining the parts electrically and further creating catalogue for the components.

INTRODUCTION : A wiring harness is an organised set of wires, terminals & connectors that run throughout the entire vehicle and transmit information and electric power, thereby playing a critical role in “connecting” a variety of components.

In this challenge we will be working on downloading the files form the te.com website and then defining the parts electrically and further creating a catalogue for the components.

CONNECTOR DEFINITION :

Following parameters are required to define any connector -

• Geometry Parameters - Points & 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 DEFINITIONS IN CATIA V5 :

1. Deutsch DT06-08SA :

Connector Mating Side : 

• Create midpoint on the contact face of mating side of Connector in Mechanical Part Design workbench.
• Creat an axis system on this point with direction defined as shown in below image.

Wire Bundle Entry Side :

• Create midpoint on the contact face of wire bundle entry side as per the image.

Define as "CONNECTOR" :

• Choose "Electrical Part Design" workbench.
• Define the part as CONNECTOR with the help of Define Connector command  in this workbench & give Type, Part Number and No. of terminals as 8 according to image.

Define Connector Connection Point :

• Select the Define Connector Connection Point command .
• Put all the inputs as shown in below image.

Define Bundle Connection Point :

• Select the Define Bundle Connection Point command .
• Put all the inputs as shown in below image.

2. Tyco 174357-2 :

Connector Mating Side : 

• Create midpoint on the contact face of mating side of Connector in Mechanical Part Design workbench.
• Creat an axis system on this point with direction defined as shown in below image.

Wire Bundle Entry Side :

• Create midpoint on the contact face of wire bundle entry side as per the image.

Clip Locking Side :

• Create midpoint on the contact face of clip locking side as per the image.
• Creat an axis system on this point with direction defined as shown in below image.

Define as "CONNECTOR" :

• Choose "Electrical Part Design" workbench.
• Define the part as CONNECTOR with the help of Define Connector command  in this workbench & give Type, Part Number and No. of terminals as 3 according to image.

Define Connector Connection Point :

• Select the Define Connector Connection Point command .
• Put all the inputs as shown in below image.

Define Bundle Connection Point :

• Select the Define Bundle Connection Point command .
• Put all the inputs as shown in below image.

Define Cavity Connection Point :

• Select the Define Cavity Connection Point command .
• Put all the inputs as shown in below image.

3. Tyco 85229-1 :

Connector Clip Mating Side : 

• Create midpoint on the contact face of mating side of Connector Clip in Mechanical Part Design workbench.
• Creat an axis system on this point with direction defined as shown in below image.

Define Cavity Connection Point :

• Select the Define Cavity Connection Point command .
• Put all the inputs as shown in below image.

 CATALOG CREATION :

• Click on File .
• Then click on New .
• Select CatalogDocument then click Ok 
• Click on Add Family command .
• Enter name of the component family .
• Then select the component type as 'Electrical' .
• Then save the catalog.

For this challenge we create two Catalog as "CONNECTOR" & "CONNECTOR CLIP".

 

CREATION OF CONNECTOR & CLIP ASSEMBLY :

• Go to Electrical Assembly Design workbench.
• Import CONNECTOR & CONNECTOR CLIP to a new assembly file.
• Arrange both parts as per required orientation.
• Use Connect Electrical Devices command .
• First chosse Clip & then Connector.
• Both will automatically connected as per given constraints.

CONCLUSION : I have learned about how to define connectors & clips as Electrical Parts as well as I have also learned about how to define assembly as Electrical Component.
