Explore Our Complete Certification PortfolioAnti-Loosening Connector for Photovoltaic Systems
Mechanical Anti-Loosening Structural Design
Innovative spring latch and self-locking thread configuration, maintaining contact resistance stability within 2mΩ through 5,000 mating cycles under UL 2238 standards. Designed to withstand force 12 wind pressure vibrations and thermal deformations across a ±50°C temperature differential, resolving the industry challenge of connector detachment in photovoltaic systems.
Long-Term Corrosion Protection System
Utilises PA66-GF30 reinforced nylon housing with nickel-plated terminals that exceed ISO 9227 standard 96-hour salt spray testing (5% NaCl, 35±2°C), surpassing UL 2849 outdoor durability requirements to ensure a 25-year operational lifespan in coastal power stations.
IP68 Sealing Protection
Triple silicone gasket configuration with epoxy resin encapsulation process, certified to IEC 60529 standard IP68 (submersion at 1 metre depth for 72 hours), achieving 99.73% waterproof yield rate (CPK≥1.67) through ISO 16949 process control system implementation.
UL 2849 Electrical Safety Assurance
Contact points feature 3μm silver plating, passing UL 2849 standard 150A overload testing and 125°C thermal ageing trials, demonstrating contact resistance ≤0.35mΩ, reducing energy consumption by 30% compared to industry standards.
Quick-Connect Waterproof Connector for Hybrid Power and Signal Transmission in Outdoor Illumination
Intelligent Signal Transmission with Interference Immunity
Dual-layer shielding architecture (aluminium foil plus tinned copper mesh) passing UL 2238 standard EMC testing, achieving a bit error rate of ＜10⁻⁹ under 30V/m electromagnetic interference, supporting parallel RS485/CAN bus transmission to meet smart city illumination control requirements.
Quick-Connect Slow-Release Ergonomics
Compliant with UL 2849 operational force standards: insertion force ≤45N/withdrawal force ≥75N, featuring tactile feedback mechanism with IPX8-rated waterproof valve, enabling single-handed blind operation and verified through 10,000 mating cycle endurance testing.
Extreme Environment Protection System
Housing constructed from UL 94 V-0 rated PPS material, certified for -40°C cold impact and +125°C thermal ageing tests, maintaining IP68 protection rating in de-icing agent corrosive environments through ISO 16949 system control protocols.
Compact Modular Design
Conforming to UL 2849 dimensional specifications, integrating 4 power and 2 signal contacts within a 21mm diameter, validated through 20kPa hydrostatic pressure testing, compatible with standard mounting apertures in roadway illumination junction boxes.
Building Technological Competitive Advantage Through Triple Certification
