Power Entry Connectors - Inlets, Outlets, Modules

1. Overview

Power entry connectors are electro-mechanical devices designed to safely establish electrical connections between equipment and power sources. They serve as critical interfaces in AC/DC power systems, ensuring reliable energy transmission while meeting safety and regulatory standards. Their importance spans across industries where stable power delivery and user protection are paramount.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
IEC Appliance Inlets	Standardized C13/C19 types, detachable connections	Computers, servers, medical devices
NEMA Receptacles	Non-locking/Locking configurations (5-15P/R, L5-30P/R)	Industrial machinery, construction equipment
Modular Power Entry Modules	Integrated filtering, switching, and fused protection	Data centers, test equipment
Medical-Grade Connectors	Double-insulated, low-leakage current design	Patient monitors, MRI machines

3. Structure and Components

Typical construction includes:

Thermoplastic housing (UL94 V-0 rated)
Copper alloy contact springs (phosphor bronze)
Insulation barriers (glass-reinforced epoxy)
Termination options: Screw/clamp terminals or PCB mounts
