Embodiment approach

[0022] image 3 Shown is the third embodiment of the present invention, the technical solution of the third embodiment is to vertically splice two foamed aluminum plates 1, the foamed aluminum plates after splicing form a right angle, and the foamed aluminum plates form a right angle One side of the positive angle is provided with a right-angle type seam pressing plate 9. A keel is arranged on one side of the internal angle formed by the foamed aluminum plate. The shielding interlayer special-shaped part 3 is two vertically connected double U-shaped structures, and the double U-shaped structure is decomposed into two U-shaped structures 11 with the interlayer 6 of the shielding interlayer special-shaped part as the dividing line, and each U-shaped structure 11 The outer layer 12 wraps the edge of every foamed aluminum plate. The right-angle joint pressing plate 9, the shielding interlayer special-shaped part 3, the foamed aluminum plate 1 and the keel 2 are fixed with screws...

Abstract

The invention discloses a foamed aluminum electromagnetic shielding splicing board, which is mainly a spliced ​​electromagnetic shielding board with a foamed aluminum plate as a base material. Including foamed aluminum boards, keels, seam pressing plates and fastening screws, the two foamed aluminum boards are spliced, a shielding interlayer special-shaped part is installed between the joints of the two foamed aluminum boards, and the shielding interlayer special-shaped part The joint pressing plate is set, and the joint pressing plate, the shielding interlayer special-shaped part, the foamed aluminum plate and the keel are fixed by the fastening screws. The special-shaped part of the shielding interlayer adopts an I-shaped structure and two vertically connected double U-shaped structures. The single U-shaped structure has the characteristics of simple process, low splicing cost and good electromagnetic shielding effect. %, easy installation and significantly lower installation costs. It can reach the national electromagnetic shielding box B level and above standard, and the electromagnetic shielding performance is obviously improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a porous metal foam aluminum electromagnetic shielding splicing board. Background technique [0002] With the rapid development of high technology, especially information technology, electromagnetic radiation in the fields of broadcast communication, information network, medical diagnosis and other fields has attracted more and more people's attention. Electromagnetic pollution is becoming more and more serious, which will seriously affect people's daily life. In addition, people pay more and more attention to the issue of network security, especially for secret-related departments to prevent information leakage or system interference, the requirements for electromagnetic shielding are getting higher and higher. [0003] In the prior art, the materials used for the electromagnetic shielding structure are mainly cold-rolled steel plates. The electromagnetic shiel...
