Wiring harness design in CATIA V5 - 3D modeling Week 4 Challenge

WIRE HARNESS ROUTING - WEEK 4

AIM:

Route the following harness layout in Electrical workbench. Make assumption for harness bundle diameters. Use Following connectors as shown in layout diagram.

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

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.<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

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

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Bundle connection point:

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

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.

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Define Bundle connection point

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Define connector connection point

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

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,

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if mso & !supportInlineShapes & supportFields]> SHAPE  \* MERGEFORMAT <![endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if mso & !supportInlineShapes & supportFields]> <![endif]-->

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.

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

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

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

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

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

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

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Now switch to Electric harness assembly workbench

select multi branchable documents

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

 

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

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]--><!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Click on Branch defination

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Then click on route defination

select connectors in between we want to create branch.

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

TO add branch point

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

select the branch then give ratio or dimension for the point

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Final wire harness routing

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

Now to create protective covering on all branches

switch to electrical harness assembly

<!-- [if gte vml 1]> <![endif]--><!-- [if !vml]--><!--[endif]-->

select protective covering then select branch - select catalog - select approprite slit cot tubes - give extrimity at start and end – ok
