FQ Series IP67 Waterproof Circular Plug Connector with Bayonet Locking Structure

Product Information

The FQ series waterproof circular plug connector is developed according to DZ4Q/RE008-84 standard requirements and represents an improved design based on the Q series connector. It combines compact structure, lightweight design, reliable connection performance, and enhanced sealing capability, making it suitable for electrical connection applications in demanding environments.

The connector adopts a bayonet quick-connection mechanism, allowing fast mating and separation while maintaining stable connection performance. Compared with traditional structures, the FQ series uses a squirrel-cage elastic contact design for female contacts, replacing conventional wire spring structures. This design helps achieve lower contact resistance, improved vibration resistance, and more reliable electrical performance during operation.

With IP67 protection capability, aluminum alloy shell construction, and gold-plated copper contacts, the connector provides effective environmental protection and stable signal or power transmission for various equipment connection systems.

Characteristics

• -- IP67 waterproof design helps protect internal contacts from dust and water exposure

• -- Squirrel-cage elastic contact structure provides stable contact pressure and reduced contact resistance

• -- Bayonet locking mechanism enables quick installation and secure connection

• -- Aluminum alloy shell with anodizing treatment improves mechanical durability

• -- Compact and lightweight structure saves installation space

• -- Gold-plated copper contacts provide reliable conductivity and corrosion resistance

Technology & Working Theory

The FQ series connector uses a precision elastic contact system to maintain consistent contact force between mating components. The squirrel-cage structure allows the contact area to remain stable under vibration and mechanical impact conditions, reducing electrical fluctuation during operation.

The bayonet coupling system achieves fast alignment and locking through a simple rotating action. The sealing structure helps prevent moisture and dust from entering the connection area, supporting reliable operation in outdoor and industrial environments.

Application / Usage

The FQ waterproof circular connector is suitable for industrial equipment, automation systems, transportation equipment, outdoor electrical devices, control systems, and other applications requiring compact and sealed electrical connections.
