Product Description
This USB 2.0 A male plug metal shell connector is designed for reliable high-speed data and power transmission in USB cable assemblies. The connector uses precision copper-alloy terminals with nickel under-plating and gold-flash contact areas to ensure low contact resistance and stable signal integrity. The solder/crimp region is bright-tin plated for secure termination to stranded wires, while the fully nickel-plated metal shell enhances EMI shielding and long-term corrosion resistance.
With a rated current of 1.5 A per pin, 500 VAC dielectric strength and ≥1000 MΩ insulation resistance, the connector provides safe and stable performance in a wide range of electronic products. The compact plug design is suitable for automatic or manual cable processing, overmolding, and customized wire harness production.

Precautions
Ensure correct cable construction and wire gauge selection to meet current-carrying requirements and temperature rise limits.
When soldering, control heating time and temperature to avoid damaging the plastic insulator or degrading plating on the terminals.
Avoid excessive insertion/withdrawal force beyond the specified mechanical limits to maintain contact normal force and connector life.
Protect open connectors from dust, moisture and chemical contamination during storage and assembly; store in a dry, clean environment.
For high-volume or harsh-environment applications (automotive, outdoor, high-humidity), contact us for enhanced plating thickness, sealing or overmolded strain-relief designs.
