• To download the P-Clamp CAD data and define it as Electrical Support in the Electrical Part design workbench and define the necessary electrical properties.
• To download the Back shell CAD data and define it as Electrical Back shell in the Electrical Part design workbench and define the necessary electrical properties.
• To create Following Corrugated tubes and add them in Catalogue under “Slit COT” family.

P-Clamp

P-Clamp is an Electrical Support equipment which provides support to the wire bundle to remain fixed to the automobile or any components or parts.

The wire bundle can enter and exit from any side as it is a bi-directional equipment.

So, we need to specify the Entry and Exit points from both sides.

To define the P-Clamp as Electrical Support equipment as per the below detail.

First, we must download the CAD part and open it using the CATIA V5 software. To define the geometry parameters, need to navigate to the Part Workbench. Then to create points and plains at the entry and exit points, to define the P-Clamp as an Electrical support we have to navigate to the Electrical Part design Workbench. By using the 'Define support part' option we can define the P-Clamp Entry and Exit points. As the P-Clamp is Bi-directional so we need to define the support two times.

BACKSHELL

A back shell is an accessory that mounts to the rear threads of a connector to enhance its operational characteristics. The primary function of a back shell is to provide strain relief, which minimizes stress from the cable, on the junction where the wires terminate to the contacts.

Back shells come in a variety of finishes, materials, and angle configurations. compatibility and aesthetics, back shells and connectors should have a matching material and finish. And to provide simple cable management, most back shells may be ordered in 45º and 90º angles.

To define the Electrical properties of the back shell we need to follow the below steps:

First download the 3-D CAD part of the back shell and open it using the CATIA V5 software.

Create mid-point at the bundle entry side.

Create a mid-point at the connector mating side.

Identify from which side the bundle will enter and the side which will mate with the connector.

Create an Axis system at the Connector mating side.

The axis system should be created at the center of the mating surface.

The axis must be defined as defined for the connectors show that it will connect easily.

Y- axis: Normal to the mating surface

X-axis: Normal to the locking side

To define the Electrical properties, we need to navigate to the Electrical Part design workbench.

There we need to define the component as the 'Back shell'.

Define the Back shell connection point.

Then define the Bundle connection point.

CORRUATED TUBES

Corrugated Tubes are used as protection coverings for the wire bundle from any type of damage.

Create a Catalogue document and add Slit COT as a family and saving the document in our desired folder.
