Embodiments of the present invention provide a wireless terminal including a PCB, an antenna, and a data connector. The PCB has a groove, which divides the PCB into a first part and a second part. 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.
