Although the USB 2.0 interface is flooded in the computer industry, it has formed the USB 3.0 Promoter Group from industry giants such as Intel, Microsoft, HP, Texas Instruments, NEC, ST-NXP Wireless, Announced that the next generation USB 3.0 standard specification to be formulated has been officially decided. In this new specification, based on the four contacts of USB 2.0, five new contacts are added, two data output and two data registration forms are adopted, and data is transmitted through the shipping list section. Therefore, it is more widely used in PC peripheral equipment and consumer electronics products, with a transfer rate approximately 10 times that of USB 2.0 and better energy efficiency.

  This USB 3.0 electrical connector has a structure including an insulating main body, a metal casing provided on the insulating main body, five additional terminals, and four USB 2.0 terminals.
