A USB connector, a PCB connected to the USB connector, and a USB device are provided. The USB connector includes a metal surface, and on the metal surface, a solid metal part is set at a location corresponding to a spring of a socket, so that the spring contacts the solid metal part after the USB connector is inserted into the socket to reduce electromagnetic interference. The USB connector may include an in-line weld leg; a metal enclosure located at the same side as the in-line weld leg fully contacts a PCB when the USB connector is connected to the PCB; and contact surfaces on the USB connector that contact the PCB are metal surfaces. The PCB includes a suppression circuit configured to suppress harmonic waves in USB data transmission.

A method and an apparatus are provided for improving a communication rate, which are used in a terminal working in a multiple-input multiple-output (MIMO) state. The method includes: obtaining strength of a first signal received in a first path connected to a first antenna and strength of a second signal received in a second path connected to a second antenna; and adjusting the first path or/and the second path according to a difference between the strength of the first signal and the strength of the second signal, so as to reduce an unbalance degree between the first path and the second path, thereby improving the communication rate. By adopting the present invention, improvement of a rate of an antenna may be achieved by adjusting a balance between the first and second paths.
