The second part is connected to the antenna, the first part is connected to the data connector through a rotating shaft, and connecting wires of the data connector are connected to the second part. The first part and the second part each have a ground. The ground of the first part is connected to a metal casing of the data connector and a ground wire of the data connector is connected to the ground of the second part and the ground wire of the data connector is electrically connected to the metal casing of the data connector.

Wireless terminal

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.

USB connector, PCB connected thereto, and USB device

The present invention provides a wireless communication device. The wireless communication device includes a mainboard and a connecting member, in which the mainboard includes a mainboard body and a mainboard end part which is connected to the connecting member; the side of the mainboard body away from the mainboard end part is connected to an antenna; and a matching network is arranged between the mainboard body and the mainboard end part and configured to control the distribution of the surface current induced by the antenna on the mainboard. By arranging the matching network between the mainboard body and the mainboard end part of the wireless communication device and changing, through the matching network, the distribution of the surface current induced by the antenna, the embodiments of the present invention may simultaneously guarantee the SAR performance and the wireless performance of a wireless communication terminal and improve the user experience.

Wireless communication device

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.
