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

Wiring Harness Assembly- Routing procedure

Aim:- To define the connectors and catalogues electrically and route the mutibranchable bundle segments according to the given schematic diagram.

Workbenches used:

Mechanical part design

mechanical Assembly design

Electrical part design

Electrical assembly design

Electrical harness assembly

Electrical harness installation

Schematic wiring Diagram:

Connectors used:

- All connectors are electrically defined using electrical part design, including bundle connection point and connector connection point.

- Axis systems are provided in the proper way, that the y axis facing to the bundle connection point.

- After definition, all are added to a single catalogue.

• DT06-08SA

• DT06-4S

• DT06-2S

• DT06-6S

Electrical harness design:

- Placing the connectors imported from catalogues.

-Arranging the connectors as per the given schematic in the assembly design workbench. Moving and rotating using manipulation commands at the distance mentioned in the diagram.

-Then switch to electrical harness assembly. The product file needs to assigned as a gemetrical bundle using the geometrical bundle tool. It will add the electrical definition into the publications.

- Using the Multi branchable document tool, add braches by connecting the main connectors.

- In the branch definition, we can define diameter and length of the bundle. Diameter of the main branch segment is taken as 15 mm.

- Use the route definition dialogue box to pick the main connectors and thier connection points as shown.

- This will change the workbench to Electrical harness installation, where, we can define budle segments and their branches.

- Using the 'add branch points' tool, make branch segments at desired lengths.

- These segments are utilised for creating sub branches to the remaining connectors.

- Branches are made using the 'branch definition' tool in the same workbench.

- Sub branches are in 10mm dia and length as per the diagram.

- Route the wires as shown by assigning proper tangent direction from the branch points.

- Sub branches can be again splitted to provide more branches using the same method.

- Using the 'protective covering' tool, add protective coverings to the segments.

- Protective coverings are previously defined in a catalogue.

- End extremity is given as 30mm.

Finalization:-

Conclusion:- Using this method, we will be able to define connection definitions in a 3d environment of an automotive for different applications.
