Wiring harness design in CATIA V5 - 3D modeling Week 2 Challenge

WIRING HARNESS DESIGN IN CATIA V5

• The entire vehicle's electrical wiring is contained within a wire harness.
• After the chassis construction is put together, the gasoline, brake, and wiring harness lines are installed.
• The wiring harness of an automobile is made up of a large network of wires.
• The electrical distribution system of a car is called a wiring harness.

Uses Of Wiring Harness:

• A wiring assembly sometimes referred to as a wiring harness, is a coordinated and ordered arrangement of cables (wires) inside of an insulating material.
• They are utilized in electrical systems and are designed to convey electrical impulses.
• Throughout the entire vehicle, a wiring harness is a logical configuration of wires, terminals, and connectors that conveys data and electrical power, essentially "connecting" a variety of different components.

Basic Terminologies Of Wiring Harness Design:

• Electrical Distribution System (EDS).
• E&E Architecture.
• Logical Schematics.
• Electrical Schematics.
• Wiring Harness Topology.
• Wiring Harness Routine.
• Wiring Harness Packaging.

Electrical Distribution System (EDS):

• It spans the entire length of the vehicle, from front to back. Power distribution, wire harness design, wiring harness component design, physical and logical architecture schematic creation, and wiring harness component design are all included.
• It guarantees the precise location of all the electrical parts that have been installed in the car.
• The logical communication between electrical components is provided by it.
• It features electrical controller units for several elements, including the engine, the airbag, and the ABS (ECU).

E&E Architecture:

• It is the diagram of high-level logical connectivity. It represents every system, every subsystem, and every logical link between them.
• The Control Area Network (CAN) between various electronic components is displayed.

Logical Schematics:

• Architectural plans for E&E in great detail.
• It displays the logical connections between various parts and controllers of a particular system and subsystem.
• It only defines electrical connectivity; it does not define any other parameters.

Work Benches For Using Wireframe Harness Design:

• Electrical Part Design.
• Electrical Assembly Design.
• Electrical Harness Installation.
• Electrical Harness Flattening.
• Electrical Harness Assembly.

Methods of Creation:

• Download igs_File Format from TE-Connectivity Website.
• Create a New Folder and Save it as (.CAT Part).
• Upload the File into Part Design Work-Bench.
• Create Position Points and Axis Systems.

Wiring Harness Assembly:

• Wires.
• Connectors.
• Terminals.
• Protection Device.
• Insulation.
• Clips & Clamps.
• Fuse & Relay Box.
• Retention Device.
• Guiding Channels.

DEUTSCH/DEUTSCH DT:

• DEUTSCH DT environmentally sealed connections are created for applications involving cable to cable, cable to board, and the device. In extreme environment applications, where even a slight connection degradation may be crucial, DT connectors are used.

AMP ECONOSEAL:

• Extreme environments call for the usage of Econoseal connectors.
• Electrical contact systems that are not effectively protected from moisture, dust, corrosive gases, and liquids prematurely age.
• The adopting Econoseal sealed housings, contact damage brought on by environmental risks can be avoided.

Connector Modeling:

Download the specified connector from te.com. In the part design workbench provide the center point and axis system to the wire inserting end and connection end. The axis must be given in a specified way:

X-axis: Towards the clamp

Y-axis: Towards the connection

Z-axis: left or right of the connector.

• Define an Electrical Part.
• Define a Connector.
• Define Bundle Connector.

Conclusion:

• Successful modeling of the connector in CATIA V5 results in its addition to the catalog for future use.
