Structural Design and Mounting Method

The connector features a through-hole (dip) mounting structure with plug-in design and tray packaging, supporting automated assembly and efficient mass production. The through-hole design enhances solder joint strength, improving PCB-level mechanical stability and reducing the risk of loosening during long-term use.

With a compact overall length of 11.5mm, the product is optimized for space-constrained applications. Its reduced footprint allows more flexible PCB layout design while maintaining structural integrity, making it suitable for miniaturized electronic devices.

Interface Standard and Electrical Performance

This connector complies with the USB 3.0 standard, enabling high-speed data transmission capabilities. The Type-A female interface ensures broad compatibility with standard USB plug devices, offering strong versatility across different system architectures.

It adopts a 9-pin contact configuration, supporting high-speed differential signal channels compared to USB 2.0 interfaces, significantly improving data bandwidth and transmission efficiency.

In terms of electrical characteristics, the rated voltage is DC 30V and the rated current is 1A, suitable for low-power data and signal applications. The contact resistance is controlled at a maximum of 30mΩ, effectively minimizing signal loss and ensuring stable transmission quality. The insulation resistance is ≥100MΩ, providing strong electrical isolation for enhanced operational safety.

The connector also passes a dielectric withstand voltage test of DC 500V, demonstrating reliable electrical durability under high-voltage stress conditions.

Mechanical Performance and Durability

The product offers a mechanical mating life of up to 1500 insertion and extraction cycles, making it suitable for medium-frequency usage environments in both industrial and consumer applications.

The insertion force is controlled within 5–35N, achieving a balance between secure connection stability and user-friendly operation. This optimized force range helps prevent loose contact issues while avoiding excessive wear during repeated use.

Even after multiple mating cycles, the connector maintains stable contact performance, reducing the risk of connection failure caused by mechanical fatigue and ensuring long-term reliability.

Material and Appearance Design

The connector features a blue insulator housing that serves both functional and structural purposes. Functionally, it provides insulation and precise contact alignment. From a manufacturing perspective, the color coding improves visual identification during assembly, reducing the likelihood of installation errors.

The overall structural design emphasizes consistency, durability, and stable long-term electrical performance through optimized material selection and engineering design.
