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.

Applications
USB charging and data cables for mobile phones, tablets and smart
devices
Power and signal wire harnesses for consumer electronics, set-top
boxes, game consoles and media players
PC and laptop peripherals, USB hubs, docking stations and external
storage devices
Automotive and industrial control equipment requiring USB interface
connectivity
Custom PCB-to-cable or device-to-device connections in embedded
systems and IoT terminals
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.
