Electrical Wiring Harness Design Engineer Interview Questions and Answers

Wire selection is the process of choosing the appropriate type and size of wire for a specific application.

• Consider the current carrying capacity required for the application

• Select the appropriate wire gauge based on the current rating

• Choose the insulation material based on environmental conditions

• Consider factors such as flexibility, temperature rating, and voltage rating

• Common wire types include PVC, XLPE, and PTFE

Clips are devices used to secure wiring harnesses in place and prevent movement or damage.

• Clips are typically made of plastic or metal and come in various shapes and sizes.

• They are used to secure wiring harnesses to vehicle body panels, frames, or other components.

• Clips can be reusable or single-use, depending on the design and application.

• Examples of clips include push-in clips, screw-in clips, and adhesive-backed clips.

The truck will run without running back while hill climbing by engaging the parking brake or using a hill start assist feature.

• Engage the parking brake to prevent the truck from rolling back while hill climbing

• Use a hill start assist feature if available to automatically hold the truck in place on inclines

• Properly shift gears and apply steady throttle to maintain forward momentum

Flattening workbench in CATIA V5 is a tool used to flatten 3D wire harnesses into 2D representations for manufacturing purposes.

• Allows designers to visualize and analyze the layout of wire harnesses in a flattened state

• Helps in identifying potential issues such as collisions or incorrect lengths

• Enables the creation of accurate manufacturing drawings and documentation

Terminals are the points where wires are connected to a device or component in an electrical wiring harness.

• Terminals can be crimped, soldered, or connected using screw terminals.

• Common types of terminals include ring terminals, spade terminals, and bullet terminals.

• Terminals can be insulated or uninsulated depending on the application.

• The choice of terminal type depends on factors such as current carrying capacity, vibration resistance, and ease of installation.

A connector is a device used to join electrical circuits together.

• A connector is a mechanical device that allows for the connection and disconnection of electrical circuits.

• Connectors typically have male and female components that fit together to establish an electrical connection.

• Connectors come in various shapes, sizes, and configurations to accommodate different types of electrical connections.

• Examples of connectors include USB connectors, HDMI connectors, and automotive e...read more

The type of connector used in electrical wiring harness design plays a crucial role in ensuring proper functionality and reliability.

• Connectors can be categorized based on their shape, size, pin configuration, and locking mechanism.

• Common types of connectors include circular connectors, rectangular connectors, blade connectors, and modular connectors.

• Connectors can also be classified as male or female, based on their design for insertion into or acceptance of another connecto...read more
