Wiring harness routing & packaging Rules Week 3 Challenge

WEEK 3 CHALLENGE WIRING HARNESS ROUTING AND PACKAGING RULES:

AIM:

To following cad data & define it as Electrical support using Electrical Part design Workbench. Define all the necessary properties at the given input.

INPUT:

1. P-CLAMP
2. BACK SHELL (TYCO 173812-1)
3. CREATE CORRUGATED TUBE AT GIVEN INPUT DATA.

P-CLAMP:

BACK SHELL:

CORRUGATED TUBE:

DESIGN METHODOLOGY:

P CLAMP:

• Get the clip 3D part from given input.
• Define the geometry parameters.
• Define part as support command.
• Define entry point and plane.
• Define base and exit plane.

Step - 1:

• First download the CAD part and open it using the CATIA V5 software.

Step - 2:

• Now we have to define the geometry parameters.
• In order to define the geometry parameters, we need to navigate to the Part Workbench.
• Then we need to create points and plains at the entry and exit points.

Step - 3:

• Now in order to define the P-Clamp as a Electrical support we have to navigate to the Electrical Part design Workbench.
• Now 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.

BACK SHELL:

Back shell are plastic molded parts used at wire entry side of connector either for protection or to improve aesthetic/ appearance of harness.

There are not mandatory parts of wirig harness. are always optional and driven by cost.

• Get the back shell 3D part in from given input.
• Define the geometry parameters.
• Define part as back shell.
• Back shell connection point.
• define bundle connection point.

Step - 1:

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

Step - 2:

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

Step - 3:

• Create mid-point at the bundle entry side.
• Create mid-point at the connector mating side.

Step - 4:

• 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

Step - 5:

• To define the Electrical properties, we need to navigate to the Electrical Part design workbench.
• There we need to define the component as the 'Backshell'.

Step - 6:

• Define the Backshell connection point.
• Then define the Bundle connection point.

3. CORRUGATED TUBES:

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

Step - 1:

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

Step - 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

35mm COT:

20mm COT:

10mm COT:

15mm COT:

5mm COT:

CONCLUSION:

• 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.
