Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge

AIM:

TO FLATTEN THE WIRING HARNESS AND DRAFT THE WIRING HARNESS ASSEMBLY.

Add protective covering on all branches connected to DT06-2S & DT06-4S connectors. Keep end extremity at 30mm (from connectors end)

Download connector 3D data from www.te.com

• DT06-4S
• DT06-6S
• DT06-2S
• DT06-08SA

DEFINIG ELECTRIC PARAMETER FLOW CHART

Convecting the Mechanical part into the Electrical part for that I had followed the following steps.

DT06-2S

DT06-4S

DT06-6S

DT06-08SA

CONNECTOR DEFINATIONS IN CATIA V5

1. Deutsch DT06 – 08SA

Connector connection point:

Create midpoint on the contact face which will be normal to wire bunddle insertion.

Craete Axis System with respect to the point which we have created and defining the axis direction as shown below,

Bundle connection point:

Switch to 'Electric Part Design'

Define the part as connector in catia, give no. of termination as 8 because we have 8 entry points for wire.

Define Bundle connection point

Define connector connection point

So like wise we need to define all the connector as electricaly.

Now Create the Electric wire harness context assembly and Geometric bundle as a subassembly containing all the electric parameters as shown below,

Add the all connectors which are electricaly defined to the Geomteric bundle assembly.

Then define this Geomteric bundle assembly as electricaly, for that we need to switch to Electric harness assembly workbench.

select Geometric Bundle then click on Geomteric bundle assembly (In specification Tree)

Now, to position all the connector as given in input file,

Create enviroment on which the bundle assembly will be placed.

Draw the sketch as given dimension in input just for referance purpose.

Switch to Mechanical assembly workbench, Position the connectors by using Manipulation, snap, smart move and compass commands.

Now switch to Electric harness assembly workbench

select multi branchable documents

Now to route the harness, after selecting multi branchable documents workbech changed to wire harness installation.

Click on Branch defination

Then click on route defination

select connectors in between we want to create branch.

TO add branch point

select the branch then give ratio or dimension for the point

Final wire harness routing

HARNESS FLATTENING:

• WE GO TO THE HARNESS FLATTENING WORKBENCH AND DEFINE THE FLATTENING PARAMETERS.
• WE USE THE EXTRACT COMMAND TO BRING THE HARNESS ASSEMBLY TO THE FLATTENING WORKBENCH HERE.
• CHOOSING A SUITABLE PLANE WE FLATTEN THE HARNESS ASSEMBLY.
• BUNDLE SEGMENTS ARE ROTATED AT THE REQUIRED ANGLES. THE HARNESS ASSEMBLY IS THEN DRAFTED.
• FLATTENING PARAMETERS ARE DEFINED IN ORDER TO MAKE THE BUNDLE AND THE CORRUGATED TUBES VISIBLE IN THE 3D DRAWINGS.
