Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] At present, the common installation and fixing methods of the signal shielding cover of the display screen include fixing through metal fixing twist feet under the shielding cover and fixing through metal clips. The above-mentioned installation and fixing methods all have the technical problems of loose shielding cover, complex structure and installation process, and poor conductivity and sealing.

[0024] See Figure 1-5 , in order to solve the abov...

Abstract

The invention relates to the technical field of a signal shielding cover, in particular to a signal shielding cover structure, comprising a superposed PCB board assembly and a hardware bracket assembly, and a shielding cover sandwiched between the PCB board assembly and the hardware bracket assembly. And a shielding area for shielding signals is arranged on the PCB component; The shielding cover abuts on the hardware support assembly and is interference-coated on the shielding area. The invention aims at providing a signal shielding cover structure. The technical scheme provided by the invention solves the technical problems of loosening of the shielding cover, complex structure and installation process, poor conductivity and tightness of the existing signal shielding cover.

Description

technical field [0001] The present invention relates to the technical field of signal shielding covers, in particular to a signal shielding cover structure. Background technique [0002] The realization of the function of the common display screen signal shielding cover is basically to fix the PCB circuit board on the hardware bracket, and then install the shielding cover on the PCB circuit board. There are several ways to install and fix the shield on the PCB circuit board as follows. [0003] One is that there is a metal fixed twisting foot under the shielding cover. Through the through hole on the PCB circuit board, the twisting direction of the metal twisting foot is deformed to fix the shielding cover on the PCB circuit board. This structure needs to add a twisting foot to twist and deform The process is fastened, resulting in complex structure and installation process; the metal fixing feet may loosen after a long period of vibration, resulting in abnormal noise; Add...
