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

Q1. 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)

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

Answer:-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 below

Then 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
