Problems solved by technology

[0002] In the field of airborne equipment in the aircraft cabin, the electronic circuits are highly integrated, and there are many airborne equipment in the cabin and the installation is relatively dense. Therefore, there is a high requirement for weight reduction of the airborne equipment. The influence of electromagnetic interference has potential safety hazards and affects flight safety. Therefore, there is an urgent need for a chassis with light weight and good shielding effect

Abstract

The invention relates to the technical field of aerospace, in particular to a composite material shielding case which comprises a case body, a front cover plate and a rear cover plate, a main body of the case body is a hollow cuboid with two open ends, and threaded mounting holes are formed in the left end face and the right end face of the case body. The front cover plate and the rear cover plate are provided with fixing holes matched with the threaded installation holes in position, the front cover plate and the rear cover plate are connected with the threaded installation holes through screws to cover openings in the two ends of the box body, and conductive sealing gaskets are further arranged at the butt joint positions of the box body and the front cover plate and the butt joint positions of the box body and the rear cover plate. The inner wall of the box body is provided with a plurality of pairs of metal clamping grooves used for clamping and fixing slot type electronic devices, each pair of metal clamping grooves are symmetrically arranged on two opposite inner walls of the box body, and the front cover plate, the rear cover plate and the box body are made of carbon fiber composite materials with the surfaces plated with copper-nickel metal layers. The cable has the advantages of light weight and good shielding effect.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a composite material shielding case. Background technique [0002] In the field of airborne equipment in the existing aircraft cabin, the integration of electronic circuits is high, and there are many airborne equipment in the cabin and the installation is relatively dense. The impact of electromagnetic interference has potential safety hazards and affects flight safety. Therefore, a light weight and good shielding effect is urgently needed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a composite material shielding cabinet, which has the advantages of light weight and good shielding effect. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A shielding case made of composite material, comprising a case body, a front cover and a rear cover, the main bod...
