This interface can be connected to hardware for data transmission without rebooting. Good performance. In 1988, the first generation of USB1.1 transmission interface was launched. In 2000, Intel released the official specification of USB2.0, which also expanded the types of computer peripheral products that can use USB transmission interface, such as mobile hard disk. , printer and mouse etc.

However, as the file capacity required for transmission increases day by day, the transmission speed of the USB2.0 connector is limited by the control chip and various factors and cannot meet the requirements of use, which also promotes the new generation of USB3.0 connection With the introduction of USB3.0 connectors, in addition to maintaining the previous structure and plug-and-play features, the USB3.0 connector has expanded its application fields to the simultaneous and real-time transmission of personal computers, consumer electronics and mobile devices, and its transmission speed is even faster than that of USB2. .0 connector 10 times, and has the advantage of low power consumption.

The USB3.0 connector is equipped with an anti-misplug function, that is, the USB3.0 plug connector can only be inserted into the USB3.0 socket connector when the direction between the USB3.0 socket connector and the USB3.0 plug connector is correct. Generally, users will not insert the USB 3.0 plug connector after observing the direction of the USB 3.0 socket connector. Basically, they feel whether the direction between the USB 3.0 socket connector and the USB 3.0 plug connector is correct through touch. If it is not correct, then re-adjust the direction of the USB3.0 plug connector, which brings inconvenience to the user.
