National standard discharge gun


1. Product compliance and design


·Standard: Comply with GB/T20234.2 - 2023 national standard (Connecting devices for conductive charging of electric vehicles-Part 2: Relevant specifications for AC charging interfaces).


·Design features: customized model injection molding process (smooth shape), ergonomic design (comfortable grip).


2. mechanical properties


·Life: No-load plugging times>10000 times (durability).


·Plugging force: Plugging force during coupling is 45N < F <100N (the operating force is reasonable to avoid too loose/too tight).


·Impact resistance: Can withstand 1 meter height drop + vehicle rolling (reliability in outdoor scenarios).


3. electrical performance


·Power-related: Rated output current 10A /16A MAX, working voltage 250V (suitable for conventional AC power supply).


·Insulation and safety:


○ Insulation resistance>1000MΩ (DC500V)(low leakage risk);


○ Withstand voltage of 2000V (resistance to electrical breakdown);


○ Terminal temperature rise


·Contact performance: Contact impedance 0.5MΩ MAX (reduces power loss).


·Protection level:


○ Gun head (coupled state): IP65 (dustproof, low-pressure water spray prevention, suitable for outdoors);


○ Insert: IP24 (anti-solid foreign matter diameter>12.5mm, anti-splash, routine indoor protection).


4. environmental adaptability


·Working temperature: -30℃ ~ +50℃ (covering severe cold and high temperature environments).


5. material properties


·Housing: Thermoplastic, flame retardant rating UL94V- 0 (self-extinguishing after leaving fire, fire safety).


·Terminal: copper alloy (excellent conductivity)+ surface silver plating (oxidation resistance, contact resistance reduction).
