PROJECT 2- CAR BACK DOOR WIRING HARNESS DESIGN

Aim: To route the Wiring harness on Given car body and Prepare flatten view drawing in CATIA V5 and to apply Protection coverings as required.

Connectors Used

These are the connectors used for the harness design. For defining connector connection point, bundle connection point, points and cavity connection point, points and axis systems are created. After that in electrical part design workbench, these are then defined as connectors. After that these are then added to connector catalogue.

Positioning of Connectors & Mounting Equipments

After defining the connectors and mounting equipments, they are then positioned on the back door. P-clamps and connectors are positioned on the suitable position.

Bundle Creation

After the positioning the connectors and equipments, harness bundle is created accordingly for the connectors, through the mounting equipments.

After the bundle creation, the harness is protected with the help of corrugated tubes of 20mm, 15mm and 10mm diameter. And the above figure shows the final assembly of back door harness.

The above figure shows checking of Harness continuity using search command. There are 0 branches found which are not continuous. Therefore the design is practicable.

Wiring Harness Flattening

First of all, i have given the harness flattening parameters and selected the appropriate options. After defining the parameters, the harness bundle is then transfered from already created product of electrical harness assembly to the electrical harness flattening product by using extract command. Then the harness is flattened using flatten command. After flattening the harness, each branch is rotated to meet the required order of arrangement. The rotation of branches is done using rotate command. The above figure shows flattened harness after rotation.

Connector catalogue, Corrugatted tubes catalogue, Part files and the assembly files are attached as .zip folder.
