Wiring harness routing & packaging Rules Week 3 Challenge

Wiring harness routing & packaging Rules Week 3 Challenge

Aim:

Define given clamp and back shell as an electrical support and electrical back shell and add their necessary properties using Electrical part design workbench in CATIA V5. And also define the corrogative tubes with thier properties.

Design methodology:

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 the sides.
• To define the P-Clamp as Electrical Support equipment we need to follow the below steps

1. Intialy download the CAD part from the TE.com at defferent formet like .igs , .step and .dxf. Than it should be convert as a CATpart.
2. Now we have to define the geometry parameters.
3. In order to define the geometry parameters, we need to navigate to the Part Workbench.
4. Then we need to create points and plains at the entry and exit points.
5. Now in order to define the P-Clamp as a Electrical support we have to navigate to the Electrical Part design Workbench.
6. Now using the 'Define support part' option we can define the P-Clamp Entry and Exit points.
7. As the P-Clamp is Bi-directional so we need to define the support two times.

Back Shell:

• A backshell is an accessory that mounts to the rear threads of a connector to enhance its operational characteristics. The primary function of a backshell is to provide strain relief, which minimizes stress from the cable, on the junction where the wires terminate to the contacts.
• Backshells come in a variety of finishes, materials, and angle configurations. For material compatibility and aesthetics, backshells and connectors should have a matching material and finish. And to provide simple cable management, most backshells may be ordered in 45º and 90º angles.
• To define the Electrical properties of the backshell we need to follow the below steps:

1. First download the 3-D CAD part of the backshell and open it using the CATIA V5 software.
2. Identify from which side the bundle will enter and the side which will mate with the connector.
3. Create mid-point at the bundle entry side.
4. Create mid-point at the connector mating side.
5. Create an Axis system at the Connector mating side.
6. The axis system should be created at the center of the mating surface.
7. The axis must be defined as defined for the connectors show that it will connect easily.
   • Y- axis: Normal to the mating surface
   • Z-axis: Normal to the locking side
8. To define the Electrical properties, we need to navigate to the Electrical Part design workbench.
9. There we need to define the component as the 'Backshell'.
10. Define the Backshell connection point.
11. Then define the Bundle connection point.

Corrugative Tubes:

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

1. Create a Catalogue document and adding Slit COT as a family and saving the document in our desired folder.
2. Creating the following corrugated tubes as per the dimensions given in the table and storing in the Slit COT family catalogue document.

Name	ID (mm)	OD (mm)	Thickness (mm)
15mm COT	12	15	1.5
20mm COT	17	20	1.5
35mm COT	32	35	1.5
10mm COT	7	10	1.5
5mm COT	3	5	1

15mm COT:

20mm COT:

35mm COT:

10mm COT:

5mm COT:

Component stored in Catalogue:

Catalogue for P-Clamp:

Catalogue for Back Shell:

Catalogue for Corrugative Tubes:

Conslusion:

• From the above assignment we learnt how to define the Electrical support for a P-Clamp and also define its Electrical properties.
• We also learnt how to Electrical Backshell for a Backshell component and also define its Electrical properties.
• We also learnt how to make Corrugated Tubes of different diameters and also save them in the respective families in the Corrugated Tubes catalogues.
