<p>A USB interface and a terminal comprising the USB interface. The USB interface comprises a USB jack (201), a first metal piece (203) and a second metal piece (207). The USB jack is fixedly connected to the first metal piece. The first metal piece is connected to the second metal piece through a first rotating shaft (205). The second metal piece is electrically connected to a grounding surface of a mainboard (30) of a PCB of the terminal. When the USB jack is rotated, the USB jack drives the first metal piece to rotate by a first predetermined angle through the first rotating shaft. The USB jack may implement a good electrical connection between a computer mainboard and the mainboard of the PCB of the terminal, and equivalently extend the length of the mainboard of the PCB of the terminal, which may obviously alleviate a problem that the insufficient length of the mainboard of the PCB of the terminal causes antenna performance to deteriorate, and effectively improve the antenna performance of the mobile terminal.</p> |
