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

Q1. Flatten the harness assembly completed in “week 4 challenge”. Place the flattened view on drawing sheet. Ensure bundles with protective coverings has different visuals on drawing view.-Report

Aim- To Make 2D drawing of routed wiring harness assembly need to make it flatten by using wiring harness flattening workbench

Download connector 3D data from www.te.com

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

  Start to make-1^St open connectors ( DT06-08SA) into Catia-v5 and define it as per the mentioned below steps

   Defining step-1 create point & axis system at center on connector connection side in part design workbench & Ensure y axis Axis normal to face & x axis along the locking direction

  Defining step-2 create point at center on bundle connection side

• 

  Defining step-3 switch into electrical part design workbench and define it as electrical component by using Define connector command & click on part, give input 8 in dialogue box for number of termination as this connector has total 8 termination points, then click OK

  step-4 use Define connector connection point command and select inputs as shown in image below

  step-5 use Define bundle connection point command and select inputs as shown in image below

  Follow above same steps to define other connectors & give respective termination points 4, 6 & 2 while defining connectors for DT06-4S, DT06-6S, DT06-2S

  Now To Route wiring to the connectors, call all the defined connectors into normal assembly design workbench & Arrange these connectors as per given layout with manipulators or axis system

  Create line as shown in image below and end of line will be at 550 mm from origin, then with snip tool arrange connector (C-DT06-6S) at this end of line as per layoutAngle assumed for branches and layout diagram constructed with point, line & axis system

  Now arrange all connectors at specified location by manipulation and snap command

  See below image

  Now, switch into electrical harness assembly workbench & with geometrical bundle command convert normal assembly into electrical Assembly, then click on multi branch able document command give highlighted inputs as shown in image (Diameter & bend radius ratio) & get into route definition and select these two connectors as shown in image below

  Now, with add branch point command add branch check below image

  Then with branch definition add branch as shown in image below

  Add another branch with branch definition command in route definition

  Add another branch point as shown n image belowThen with branch definition command in route definition add remaining braches

  Now, add protective coverings

  Use light protective covering command to add protective covering and select through document COT Tubes of higher diameter, now bundle diameter is 10mm , so choose 15mm diameter COT tubes as protective covering as shown in image below

  Then click on end extremities nearer to connectors and give value of 30mm away from connector

  Repeat same for other branches also

  Wiring harness Flattening:-

  Step-1 Make sure all connector orientation are placed properly if not then make it by using manipulator from assembly design workbench

  From below image for cross marked connectors orientation to be changed in such a way that locking faces are to towards viewing screen direction

  Below image shown corrected position by using manipulator

  Step-2

  Now, to prepare 2D drawing switch into electrical harness flattening workbench as shown in image below after opening new product file

  Step-3

  Set the parameters using harness flattening parameter command

  In flattening orientation keep as it is default plane

  In scaling choose with no scaling, we have scope to scale in further

  Synchronization and link to be kept by default

  In drawing setting select contrast option for bundle and protective covering to understand easily while preparing drawing

  Now save this product file & also save the created harness assembly product file into same path

  And then using window tile vertically command to select created wiring harness assembly for flattened assembly. Click on extract command, then click on harness assembly and extract into product file(wiring harness flattening)

  Now click on flatten command to flatten routed bundle for drawing

  Then it will converted as shown in image below

  Now, start preparing drawing from start-mechanical design-drafting

  Activate front view and then switch into flattening window for view

  Now, bundle segments are visualzing go to view properties and activate 3D wireframe view option

  As shown below

  Now change sheet size to fit view into sheet, now it is A3, change to A1, A2 check appropriate sheet size

  Noe, go to edit-sheet background and click on frame and title block

  ADD TEXT USING TEXT BOX FOR NAMING CONNECTORS
