Heavy Duty Connectors - Frames

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

Type	Functional Features	Application Examples
Modular Frame Systems	Customizable slot configurations, tool-less assembly	Automated production lines
Panel Mount Frames	Front-access design, integrated strain relief	Control cabinets in chemical plants
Weatherproof Frames	IP67+ sealing, corrosion-resistant coatings	Outdoor power distribution units
High-Voltage Frames	Extended creepage distances, arc-resistant materials	Railway traction systems

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
