With the development of electronic technology, portable electronic devices are becoming more and more widely used by consumers. The transmission requirements of massive data have prompted the corresponding interface connectors to be continuously upgraded to support massive data transmission.

The main electronic devices on the market are equipped with standard USB interfaces that support hot swapping, such as USB2.0 interface.

The maximum transfer rate of the USB2.0 interface is 480Mbps. There is also an eSATA interface on the market. The full name of eSATA is External Serial ATA (external serial advanced technology accessory). It is an external extension specification for SATA interface. It uses a 7-pin data cable and also supports hot plugging. The transmission rate is 3000Mb. /s.

Although the eSATA interface has outstanding advantages in use, it also has some shortcomings. eSATA only provides a data interface and lacks power supply. That is, the eSATA interface-based device must use an additional configuration power supply, and if the user is hot swapping The order of insertion and removal of the data cable and the power cable is incorrect, which causes the hot plug function to fail and cannot be used, and even affects the performance of the eSATA.

With the development of technology, there have been eSATA plugs and sockets that integrate power and data lines, such as the Chinese patent application number 200620158798. 3, which realizes that the eSATA plug and socket pass the power and data lines through a single The interface is connected, which is convenient for the user to perform hot swapping at one time.

From a market perspective, the improved eSATA interface does not immediately replace all standard USB interfaces, so a USB PLUS socket that is compatible with high-speed eSATA (3Gbps) plugs and low-speed USB2.0 (480Mbps) plugs has emerged. For example, the Chinese patent with the application number 200620002331.X realizes that whether it is standard USB or eSATA, the connectors of the two different protocols can share the same socket.
