Abstract

A USB (Universal Serial Bus) 2.0, eSATA (external serial advanced technology attachment) and USB 3.0 three-in-one connector is provided with a plastic body (1) and a metal frame (2). The plastic body is provided with a USB 2.0+eSATA female seat (11) and a USB 3.0 female seat (12). A first detecting terminal (121) is arranged inside one lateral wall of the USB 3.0 female seat. The metal frame is provided with metal spring plates (21), which are arranged in the frame along two lateral walls of the USB 3.0 female seat. The metal spring plates come into contact with the first detecting terminal when the USB 3.0 female seat is in plug-in connection with an external USB 3.0 male plug. The connector is simultaneously provided with USB 2.0, eSATA and USB 3.0 connection ports, thereby having extremely excellent compatibility. Moreover, the space occupied by the connector is obviously smaller than the space needed by respectively installing a USB 2.0+eSATA connector and a USB 3.0 connector, whereby the three-in-one connector can greatly save installation space and cost.
