Our high current charging pins (heavy-duty spring-loaded pogo pins) are micro-precision electrical contact components engineered to transmit high electric currents safely and efficiently. Designed to overcome the limitations of standard low-power connectors, these high-current charging pins feature custom internal structures (such as bias plunger, ball, or sleeve designs) to maintain low, stable resistance under continuous high loads.
They are widely utilized in modern high-power, fast-charging, and industrial power delivery equipment:
New Energy Vehicles & AGVs: Used in automated guided vehicles (AGVs), service robots, and electric bikes for high-current automatic charging dock systems.
Smart Fast-Charging Docks: Ideal for fast-charging cradles of smartwatches, high-power smart devices, and high-performance wireless power tools.
Industrial Automation Equipment: Provides secure, heavy-duty electrical contacts for power systems, dynamic machinery fixtures, and factory automated test beds.
Military & Aerospace Systems: Delivers rugged, high-reliability power connections under harsh conditions and continuous mechanical vibrations.
High Amperage Capacity: Specifically engineered to safely handle currents ranging from 3A to 20A (and beyond on custom designs) without overheating or causing voltage drops.
Low & Stable Contact Resistance: Special internal construction guarantees exceptionally low, constant contact resistance (less than or equal to 10 mΩ to 30 mΩ), optimizing power transfer efficiency.
Excellent Heat Dissipation & Corrosion Resistance: Machined from high-conductivity brass or copper alloys with a thick gold-on-nickel plate, preventing thermal buildup and oxidation.
Robust Lifecycle Durability: Equipped with reinforced, high-tension internal springs that maintain reliable contact force over 100,000 smooth compression cycles.
Automated Assembly Precision: Features flat-bottom or stepped-body collar shapes, perfect for seamless automatic pick-and-place placement and reflow soldering.
We are an all-around direct source manufacturerwith over 10 years of professional CNC machining and micro-precision metal component manufacturing experience.
Direct Factory Price Advantage: Source directly from our manufacturing workshop to eliminate trading margins and maximize your procurement cost efficiency.
