Radio frequency shielding device and terminal

Abstract

The invention provides a radio frequency shielding device and a terminal and belongs to the electronic device design technical field. The invention aims to solve the problem of mutual interference of various radio frequency systems of a smart phone caused by a poor shielding effect which is further caused by the poor flatness of the shielding cover of the smart phone. The radio frequency shielding device of the invention includes a printed circuit board (PCB) main board and a plurality of conductive foam elastic sheets; the printed circuit board (PCB) main board is provided with at least one radio frequency circuit; exposed copper regions are arranged around each radio frequency circuit; and the conductive foam elastic sheets are arranged on the exposed copper regions and are connected with the shielding cover of the terminal. With the radio frequency shielding device of the invention adopted, the problem of a poor shielding effect caused by the difference of pressure applied by screws to fix a main board which is further caused by the poor flatness of an aluminum magnesium alloy shielding cover can be solved, and therefore, the problem of the interference of radio frequency systems which is caused by the poor shielding effect of the aluminum magnesium alloy shielding cover can be solved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment design, in particular to a radio frequency shielding device and a terminal. Background technique [0002] Due to the poor shielding effect of current smart phones, each system interferes with each other. In the design of ultra-thin mobile phones, due to the limitation of the thickness of the mobile phone, the aluminum-magnesium alloy shielding scheme is adopted, but this scheme has the problem of poor flatness of the aluminum-magnesium alloy shielding cover, which makes the shielding effect poor and leads to the mutual interference of the radio frequency system. Contents of the invention [0003] The object of the present invention is to provide a radio frequency shielding device and a terminal, which are used to solve the problem that the shielding effect of the smart phone is poor due to the poor flatness of the shielding cover, which leads to the mutual interference of various ra...
