Project 2

Aim: To route the wiring harness on the given backdoor assembly and prepare the flatten view drawing in CATIA V5.

Objective: The objective of this project is to route the wiring harness and prepare flatten view drawing for the Backdoor of the car. All types of packaging rules have to be considered while routing the harness and industry based practices shall be demonstrated in harness design. All necessary details like clearance, clipping/clamping selection, harness fixing requirements, harness continuity should be provided in order to design the wiring harness.

Choosing right components for the wire harness routing.here we are using the components for backdoor upper and lower lights,wiper motor,sensors,and defogging equipment.the connectors used are first elecrically defined and then added to the catia model.

The type of connectors used are given below-

1- Interconnection connector

2- 2 pole connector used for light,sensors,motors.

3- Clip and clamp is used to set the location of wire.

Adding connectors and needed equipments:

Opening the equipments in catia and using the snap and smart move and positioning the connectores and supports.

The first part we position here is the interconnection connectors.

Bundle routing:

The routing starts with interconnection connector placed on the L clip

Adding protective covering to the harness bundle

By using protection covering tool we protect all the bundle.we have created a catlouge and we add the protection cover of 15mm diameter and 10 mm diameter.here we Create a gap from the end and start extremity.

Create flatten view

Now we open a new product file for the Electrical harness Flattening.here we save the already made geometrical bundle segment and we extract the geometrical bundle to flatten harness by apply flattening parameters we flattten the geometrical bundle.

once the branches are flattened we do some modification in the branches using the Rotate,bend,straighten etc tools in the Electrical harness flattening.

Creating a flatten view drawing:

After the modification we synchronize the changes wich are done to the real file and then we open new file for drawing using A0 size having scale of 3:4.and we extract the flattened model to the new drawing sheet made.

Conclusion - Routing of the wiring harness for the car Backdoor assembly has been succesfully done and prepared flatten-view drawing in Catia V5 as per the design requirements.
