FQ Series 3 Pin Waterproof Circular Plug Connector – Shell Size 14

Product Description

The FQ Series 3 Pin Waterproof Circular Plug Connector is designed for dependable electrical connections in equipment exposed to moisture, vibration, and demanding operating conditions. Manufactured according to the DZ4Q/RE008-84 standard, the FQ series is an upgraded version of the traditional Q series, offering improved environmental protection and a more reliable contact structure.

A distinctive feature of this connector is its squirrel-cage elastic female contact design, which replaces the conventional wire spring structure. This optimized contact system helps maintain stable electrical conductivity while reducing contact resistance during repeated mating cycles. Combined with a quick bayonet locking mechanism and IP67 protection, the connector is suitable for industrial equipment that requires secure and efficient connections.

Key Features

-- Bayonet locking system enables fast connection and disconnection while helping maintain a secure mechanical fit.

-- IP67 protection helps reduce the influence of dust and water during normal outdoor or industrial operation.

-- Squirrel-cage elastic contacts provide stable contact force and support consistent electrical performance.

-- Gold-plated copper contacts help improve conductivity and reduce oxidation during long-term use.

-- Compact aluminum alloy shell with anodized surface treatment offers corrosion resistance and mechanical strength.

-- Designed for repeated installation with a rated mechanical life of up to 500 mating cycles.

Design Principle

The connector transfers electrical power or signals through precision-machined gold-plated contacts housed inside an insulated body. After the plug is inserted, the bayonet coupling locks the connector into position, helping maintain stable contact under vibration and movement. The sealing structure works together with the housing to provide environmental protection suitable for industrial applications.
