Rectangular Connectors - Adapters

1. Overview

Rectangular connectors - adapters are electromechanical devices that bridge incompatible interfaces between systems or components. They enable signal, power, or data transmission across dissimilar connector standards while maintaining electrical integrity. These adapters are critical in modern electronics for ensuring interoperability in industrial automation, telecommunications, and consumer devices. Their modular design supports rapid system integration and legacy system upgrades.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
D-Sub to USB Adapter	Converts analog signals to digital protocols	Industrial PC peripherals
HDMI to VGA Adapter	Translates digital video to analog signals	Conference room projectors
Power Interface Adapter	Matches voltage/current requirements	Medical imaging equipment
Fiber to Ethernet Adapter	Optical to electrical signal conversion	Data center infrastructure

3. Structure and Components

Typical construction includes:

Die-cast metal/plastic housing for EMI shielding
Gold-plated phosphor bronze contact pins
Polymer insulation with <100M resistance
Threaded coupling mechanisms (0.5-2.0Nm torque)

Technical composition features dual-row contact arrangements conforming to IEC 60603 standards, with integrated strain relief systems for cables.

4. Key Technical Specifications
