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

AIM-:

• DOWNLOAD ALL CONNECTOR FROM TE.COM.
• ELECTRICALLY DEFINE ALL CONNECTOR.
• CREATE MULTIPLE BRANCH BETWEEN ALL CONNECTOR.

1. DOWNLOADING THE FILE

• Go to the "CAD Files" then download the ".igs" file. (Which one is highlighted from yellow colour).

• Do the same to download all the files.

2. DEFINE CONNECTOR USING ELECTRIC PART DESIGN

• Open the download file in Catia.
• Go to the "Part Design" Work bench by clicking on "Start" then "Part Design".
• Create two point in middle portion for entry and exit point.

A) CONNECTOR (C-DT06-08SA)

(i) CREATE REQUIRED GEOMETRICAL PARAMETERS

• Create connector connection point and bundle connection point.

• Create the axis on Connector connection point.

• The “Y axis” should be in the direction of mating face by right click on X axis and rotate by giving angle value.
• “X axis” on the horizontal direction and “Z axis” in the Top direction by right click on Y axis and rotate by giving angle value.

(ii) DEFINE PART AS CONNECTOR

• Go to the “Start” then choose “Equipment & Systems” then choose “Electrical Harness Discipline” then choose “Electrical Part Design”.
• Go to the “Electrical Part Design” workbench.

• Go to the “Electrical Device Definition” then choose “Define Connector” option.

• Click on the body for Connector Definition box.
• In “Type” option choose “Single Insert Connector”
• For “Part Number” save name as it is.
• For “Number of Terminations”, Count the number of hole and put the value.

• Termination point is created on the feature tree.
• Can change the name or save it as it is.

(iii) DEFINE BUNDLE CONNECTION POINT

• Go to the “Electrical Connection Point Definition”.
• Choose “Define Bundle Connection Point”.

• Select the Connector body for Bundle connection point definition box.
• “Name” left it as it is or right the name here.
• Choose “Representation” option and choose the mating face of connector.
• Choose “Point” option and select the point from connector.
• Choose “Initial Condition” and select the mating face of connector again.
• Then click on ok.

(iv) DEFINE CONNECTOR CONNECTION POINT

• Go to the “Electrical Connection Point Definition”.
• Choose “Define Connector Connection Point”.

• Select the connector body for Connector Connection Definition box displayed.
• For “name” left it as it is.
• Choose “Representation” option then select the entry point of connector.
• Choose “Contact” option then click on the mating face of the connector.
• Choose “Coincidence” option and select the “Y axis”.
• Choose “Orientation” option and select the “X axis”.
• Click on ok.

• When the Electric Connector is define save the .Cat file.

DEFINE ELECTRIC TO ALL CONNECTOR BY FOLLOW STEP (i) TO (iv).

3. CREATE SKETCH OF BRANCH WITH DIMENSION

• Go to the Mechanical part work bench.
• Select "Positioned Sketch", then select palne as "Reference" and "point" as Origin "Reference".

• Create sketch by follow given dimension in challenge.

• Create sketch ith fully Constrained define.

• Save the sketch.

4. CREATE BRANCH

• • Go to the “Electrical Harness Assembly workbench.
  • Copy and paste all connector here.
  • Highlight “Product” from feature tree, then select “Geometrical Bundle” command then click on “Multi Branchable Document”.
  • Click on “Branch Definition”, then “name” it and put the “Diameter” value and “Bend Radius Ratio” and “Slack (%)” value.
  • Go to the Route Definition option.

• Select first object then second object then click on ok.
• Give “Slack (%)” value according to smooth bend then click on ok.

• Click on “add Branch Point” option.
• Select Branch then give the “Length” value, where Branch point is created then click on ok.

5. PROTECTION COVERING

• "Exit" from the Multiple Branch Definition display.
• Select "Protection Covering" option.
• Select Branch on “Bundle Segments”.

• GO TO THE “PROTECTIVE COVERING” ICON, SELECT CATALOG OF COT TUBE.

• SELECT COT TUBE.

• Select Cot Tube End Extremity and give distance of 2mm. Then click on ok.
• By follow same procedure, create “Protection Covering” for all branches.
