Abstract

As key current-conduction parts, pin material and contact quality of a convertible plug power adapter directly affect performance. The convertible plug power adapter uses high-conductivity copper alloy with gold plating to lower contact resistance. This convertible plug power adapter covers contact resistance, full-load temperature rise and thermal conductivity of materials, ensuring pins stay cool and stable under high-power output for fast charging.

1. Pin Conductive Material Parameters

Pin bodies of the convertible plug power adapter use brass or beryllium copper alloy with high conductivity and elasticity. Pins of the convertible plug power adapter are nickel-then-gold plated for wear and oxidation resistance. High thermal conductivity of the convertible plug power adapter material aids heat dissipation.

2. Contact Resistance Parameters

Initial contact resistance between pin and socket of the convertible plug power adapter is below 35mΩ. After 3,000 insertions, contact resistance of the convertible plug power adapter still stays below 45mΩ with controlled growth. Low resistance of the convertible plug power adapter reduces voltage drop and heating loss.

3. Full-Load Temperature Rise Parameters

At rated full load, pin temperature rise of the convertible plug power adapter stays within 25K. Under high current, pins of the convertible plug power adapter remain cool and housing meets safety limits. After stabilization, temperature of the convertible plug power adapter no longer rises with good thermal balance.

4. Contact Stability Parameters

Pins of the convertible plug power adapter use a spring contact structure to stay reliable under vibration. Contact pressure of the convertible plug power adapter is moderate without deformation over long use. Contact resistance of the convertible plug power adapter stays stable under temperature change.

5. Value for High-Power Application

Excellent conduction of the convertible plug power adapter supports high-power fast charging for large current needs. It reduces pin heating risk and extends unit life.

Conclusion

With low contact resistance and good heat-dissipating materials, the convertible plug power adapter ensures stable high-power output. For a high-conductivity convertible plug power adapter, contact Simsukian for material and temperature test reports.
