FQ Series Waterproof Circular Connector Socket – 5 Pin High Reliability Electrical Connection Solution

Product Description

The FQ Series Waterproof Circular Connector Socket is a compact and durable electrical connection solution designed for equipment requiring stable power and signal transmission under demanding operating conditions. Manufactured according to the DZ4Q/RE008-84 standard, the FQ Series features an upgraded waterproof structure, reliable contact performance, and excellent mechanical durability.

This 5-pin socket connector provides a balanced solution between connection capacity and installation space. With a rated current of 10A and rated voltage of 400V, it is suitable for applications requiring dependable electrical connection performance in compact equipment systems.

The connector adopts an advanced squirrel-cage elastic contact structure, replacing traditional wire spring contact designs. This optimized structure maintains stable contact pressure, reduces contact resistance, and improves resistance to vibration and mechanical impact. The gold-plated copper contacts ensure excellent conductivity, corrosion resistance, and long-term electrical stability.

The bayonet quick-locking mechanism allows fast connection and secure positioning, improving installation efficiency. The aluminum alloy shell with anodized surface treatment provides a lightweight yet strong housing, offering additional protection and durability for professional equipment applications.

Technical Specification

Working Principle

The FQ Series socket connector achieves reliable electrical transmission through precision-designed contact terminals. After the plug is inserted and locked through the bayonet mechanism, the elastic contact structure creates stable contact pressure between terminals, ensuring efficient current flow and reducing connection instability caused by vibration or environmental changes.

The sealed housing design protects the internal contact system, helping maintain consistent performance in applications exposed to moisture, dust, and temperature variation.
