Problems solved by technology

Although the signal line is wrapped with a ground wire to shield interference, there may still be a potential difference between the ground wire and the board body. This potential difference will generate a common-mode current on the ground of the RF line, thereby causing interference and deteriorating the signal on the signal line. quality

Abstract

The invention discloses a mobile terminal comprising a board body for grounding; a main board mounted on the board body; an antenna mounted on the board body; a radio frequency line including a signal line, a ground wire surrounding the signal line and an insulating rubber surrounding the ground wire, the signal line being electrically connected between the main board and the antenna, and the insulating rubber having an opening; and a conductor piece which passes through the opening and is connected electrically to the ground and grounded with the board body. The ground wire of the radio frequency line is electrically connected to the board body through the conductor piece to be grounded so as to ensure that no potential difference is generated between the board body and the ground wire and the influence on the quality of signals on the signal line is further reduced.

Description

technical field [0001] The present invention relates to the field of mobile technology, in particular to a mobile terminal. Background technique [0002] An existing mobile terminal includes a board for grounding, a main board and an antenna installed on the board. In mobile terminals, a radio frequency cable is often used to transmit the radio frequency signal of the motherboard to the antenna. Although the signal line is wrapped with a ground wire to shield interference, there may still be a potential difference between the ground wire and the board body. This potential difference will generate a common-mode current on the ground of the RF line, thereby causing interference and deteriorating the signal on the signal line. quality. Contents of the invention [0003] The main purpose of the present invention is to propose a mobile terminal that improves the quality of the signal on the signal line of the radio frequency line. [0004] A mobile terminal, comprising: a bo...
