Product Description
-
Dedicated 2-Pin High-current Design for Higher Power Transmission Efficiency: Featuring an independent dual-pin pure power supply structure, this connector realizes centralized circuit load distribution. Adopted thickened integrated high-conductivity copper terminals with ultra-low internal resistance, it produces negligible temperature rise and power loss under continuous 50A full-load operation, maintaining stable and efficient power output during long-duration high-power working conditions.
-
Modified PA66 Housing with Outstanding Comprehensive Protection Performance: The connector shell is made of upgraded flame-retardant PA66 material with specialized anti-shock and anti-brittle modification treatment. It delivers superior compression resistance, bending resistance and crack toughness compared with ordinary plastic materials. With reliable flame retardancy and insulation properties, it withstands long-term outdoor UV exposure, extreme temperature differences and mild chemical corrosion for durable outdoor service.
-
Precision Circular Self-locking Structure for Quick & Easy Mating: Designed with high concentricity for smooth plugging and effortless manual locking. The uniform thread engagement ensures tight, seamless and stable connection after locking. It effectively resists daily equipment vibration and mechanical shaking, completely avoiding hidden risks such as poor contact and intermittent power failure.
-
IP67 Integrated Waterproof Structure for All-Weather Reliable Operation: Equipped with integrated annular sealing gaskets and precision-fitted end faces, the connector achieves full-angle dead-angle-free sealing. It effectively blocks rainwater, dew, dust and humid air from penetrating internal connection parts, enabling steady operation in harsh environments including open-air installation, humid workshops and outdoor equipment cabins throughout the year.
