Electromagnetic shielding device for electronic equipment

Abstract

The invention discloses an electromagnetic shielding device for electronic equipment, which relates to the technical field of electronic communication equipment shielding, comprising a mounting base plate and a supporting plate, a protective component is installed between the mounting base plate and the supporting plate, and a device is arranged above the supporting plate The main housing, and the main housing of the device is fixedly connected with the main body of the electromagnetic shielding device, and the center of the bottom outer wall of the main housing of the device is fixedly connected with the rotating column; the present invention utilizes the provided swing assembly, which can be used during actual operation. Through the operation of the reciprocating push rod motor, the rack is driven to move back and forth in the horizontal direction, and through the transmission action of the rack and the gear, it can drive the rotating column and the main housing of the device with the main body of the electromagnetic shield installed to swing back and forth, and finally Form a fan-shaped area. In this area, it can effectively protect against external electromagnetic interference. Compared with traditional fixed devices, this design can effectively reduce the weak points of electromagnetic shielding to ensure an all-round shielding effect on the entire area.

Description

technical field [0001] The invention relates to the technical field of shielding of electronic communication equipment, 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 the corresponding electromagnetic shielding measures cannot be taken, the performance of the electronic equipment related to command and communication will be degraded, thus affecting the combat process and even the success or failure of the war. As we all know, any electronic device can work normally only in a certain electromagnetic environment. Experiments have shown 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, and once its electromagnetic shielding conditions are damaged, it will...
