1. Overview

Heavy Duty Connectors - Frames are robust mechanical structures designed to support and protect high-current or high-voltage electrical connections in demanding environments. These frames serve as critical components in industrial systems, ensuring reliable power transmission and signal integrity while withstanding mechanical stress, temperature extremes, and environmental contaminants. Their importance spans across automation, energy infrastructure, and transportation sectors where failure prevention is paramount.

2. Main Types and Functional Classification

3. Structure and Components

Typical frames consist of: - Aluminum Alloy Housing: Provides structural integrity with weight efficiency - Copper Alloy Conductors: Ensures low-resistance electrical paths ( 98% conductivity) - Polyamide Insulation: Maintains dielectric strength up to 8kV - Mechanical Locking System: Anti-vibration latches meeting MIL-STD-810G - Thermal Management Fins: Dissipates heat at current loads >200A

4. Key Technical Specifications

5. Application Fields

• Industrial Automation: Robotic welding systems, CNC machine tooling
• Renewable Energy: Wind turbine converters, solar inverter arrays
