Abstract

The embodiment of the invention relates to a structure for preventing an electronic element from interference and a mobile terminal. The structure comprises at least one shielding case, wherein the shielding case is provided with an upper wall and a peripheral side wall, and is matched with a printed circuit board provided with an electronic element to form an accommodating space so as to accommodate the electronic element in the accommodating space, thus preventing the electronic element from interference; and the printed circuit board is arranged on the shielding case; the lower part of the side wall of the shielding case is provided with a part capable of conducting electricity, the part capable of conducting electricity is in reliable contact with the printed circuit board under the action of the outside pressure borne by the shielding case, and the shielding case is earthed. In the embodiment of the invention, the structure can effectively prevent the electronic element from interference, and the shielding case in the structure can be in reliable contact with the printed circuit board by means of the part capable of conducting electricity under the action of the outside pressure, thus the shielding case and the printed circuit board can be in reliable contact to realize reliable earth connection on the premise of not adding any SMT (surface mounted technology) welding process.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic communication, in particular, a structure and a mobile terminal for preventing interference with electronic components. Background technique [0002] Wires, components, circuits or systems in mobile terminals are easily affected by external radio frequency radiation, especially mobile terminals represented by mobile phones. The TDD (Time Division Duplex) noise problem caused by radio frequency radiation has always plagued the industry , giving users a bad experience. The usual manifestations of TDD noise are: 1. During the voice call, the earpiece can always hear the obvious Weng Weng current sound; 3. When a call comes in, at the moment when the call is connected, there is a creaking noise in the receiver, and then the noise disappears; 4. During the call, in some areas with poor signal, a Weng Weng current sound suddenly appears, and the signal becomes better After disappear...
