Technical Advantages
- Enhanced Gold Plating
- Gold-plated surfaces reduce contact resistance (≤5mΩ), ensuring signal integrity for low-power Bluetooth charging.
- Anti-oxidation properties extend lifespan, preventing corrosion from humidity or sweat.
- Multi-Core Integration
- 5 independent cores integrate “power + data + ground” functions, compatible with Qi wireless charging and custom protocols.
- Slot-sealed plastic insulation guarantees inter-contact withstand voltage ≥500V, eliminating short circuits.
- Miniaturization & Durability
- Brass spring mechanism with adjustable force (0.5N–1.5N) suits varied charging case depths.
- Stainless steel variant supports IP67 certification (optional) for outdoor/industrial use.
