Electromagnetic shielding device for electronic equipment

Abstract

The invention discloses an electronic equipment electromagnetic shielding device, and relates to the technical field of electronic communication equipment shielding, the electronic equipment electromagnetic shielding device comprises a mounting bottom plate and a supporting plate, a protection assembly is mounted between the mounting bottom plate and the supporting plate, a device main shell is arranged above the supporting plate, and an electromagnetic shielding device main body is fixedly connected to the device main shell; a rotating column is fixedly connected to the center of the outer wall of the bottom of the device main shell; according to the electromagnetic shielding device, by means of the arranged swing assembly, in the actual operation process, the rack can be driven to move back and forth in the horizontal direction through operation of the reciprocating push rod motor, the rotating column and the device main shell provided with the electromagnetic shielding device body can be driven to swing back and forth through the transmission effect of the rack and the gear, and finally a fan-shaped area is formed. In the area, external electromagnetic interference can be effectively protected, and compared with a traditional fixed device, the design can effectively reduce weak points of electromagnetic shielding so as to ensure the omnibearing shielding effect on the whole area.

Description

technical field [0001] The invention relates to the technical field of electronic communication equipment shielding, in particular to an electromagnetic shielding device for electronic equipment. Background technique [0002] In the future information warfare, the battlefield electromagnetic environment will be extremely complex. If corresponding electromagnetic shielding measures cannot be taken, it will inevitably lead to the degradation of the performance of electronic equipment related to command and communication, which will affect the combat process and even the success or failure of the war. As we all know, any electronic device can only work normally under a certain electromagnetic environment. Experiments have proved that when the electromagnetic radiation exceeds its threshold, the electronic device will lose its function. In wartime, all kinds of electronic equipment will be in a very harsh electromagnetic environment. Once their electromagnetic shielding conditio...
