Description
Technical field
The utility model is related to a kind of cellular board, more particularly to a kind of electromagnetic shielding cellular board.
Background technology
Cellular board is a kind of general ornament materials that is of wide application, with light weight, incompressible and bending resistance
Good advantage, is mainly used on aircraft, rail vehicle and car, in track vehicular field, extensive with electronic equipment
Using so that it is extremely complex in the electromagnetic environment of some particular surroundings Trains, usually can be by various during electronic device works
Electromagnetic interference, includes the interference and interference from miscellaneous equipment of itself, while can also produce electromagnetic interference, electricity to miscellaneous equipment
If the permissible value that magnetic disturbance has exceeded equipment will influence the normal work of equipment, therefore, a kind of electromagnetic shielding cellular board of invention
It is significant.
Utility model content
For a variety of deficiencies of prior art, in order to solve the above problems, it is proposed that a kind of electric conductivity is strong, electromagnetic shielding effect
Really good cellular board.
The technical solution adopted in the utility model is as follows:
One kind electromagnetic shielding cellular board, including two-layer panel and the honeycomb core between two-layer panel, two-layer panel
Welded respectively with honeycomb core, the honeycomb core coating surface has layers of copper, is respectively welded between the honeycomb core and two-layer panel
Copper mesh.
Further, the layers of copper is chemical plating copper layer or copper electroplating layer.
Further, the honeycomb core is made up of aluminium foil, stainless steel foil or copper foil.
Further, the honeycomb cross section of the honeycomb core is regular hexagon.
Further, the panel is aluminium sheet, carbon steel sheet or stainless steel plate.
The beneficial effects of the utility model are:
The utility model is in honeycomb core coating surface copper, while being respectively welded copper between honeycomb core and two-layer panel
Net, so as to substantially increase the capability of electromagnetic shielding of cellular board, expands the application of cellular board, high, rigid with intensity
Greatly, the characteristics of stability is good, electric conductivity is strong, effectiveness is good.
Brief description of the drawings
Fig. 1 is side sectional view of the present utility model;
Fig. 2 is copper mesh structural representation of the present utility model.
In accompanying drawing:1- panels, 2- honeycomb cores, 3- layers of copper, 4- copper mesh.
Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, with reference to of the present utility model
Accompanying drawing, clear, complete description is carried out to the technical solution of the utility model, based on the embodiment in the application, this area is general
Other class be the same as Examples that logical technical staff is obtained on the premise of creative work is not made, should all belong to the application
The scope of protection.
The utility model is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
Embodiment one:
As shown in figure 1, a kind of be electromagnetically shielded cellular board, including panel 1 and honeycomb core 2, the panel 1 has two layers, institute
Honeycomb core 2 is stated between the two-layer panel 1 and is welded with two-layer panel 1, the panel 1 is aluminium sheet, carbon steel sheet or stainless steel plate,
The honeycomb core 2 is that aluminium foil, stainless steel foil or copper foil are prepared from by using the mode of solder brazing, wherein, the thickness of foil
Spend for 0.005-0.5 millimeters, the honeycomb cross section of the honeycomb core 2 is regular hexagon, and its length of side is 2-30 millimeters, this kind of stratiform
Architecture quality is light, and bending resistance is good and isotropism, and firm performance is good between layers, security performance height, secondary operation
Performance is good, with the heat-insulated effect that absorbs sound.
The surface of honeycomb core 2 is plated with layers of copper 3, the honeycomb core 2 and two by way of electroless copper or electro-coppering
Copper mesh 4 is respectively welded between deck panels 1, the electrical conductivity of copper is 103.06%, and electrical conductivity is high and moderate, plating layers of copper 3
Basic role with setting copper mesh 4 is to provide enough current load abilities, improves the capability of electromagnetic shielding of cellular board, such as Fig. 2
Shown, the mesh of copper mesh 4 is smaller, and line footpath is thicker, and shield effectiveness is better, the good spy of conductive strong, effectiveness
Point.
Cellular board of the present utility model is lightweight, save material, and its honeycomb is different from what in the market was generally used
Using the gluing obtained honeycomb of adhesive, but it is made by the way of solder brazing, is simple metal knot without using adhesive
Structure, therefore, it can to its secondary welding, can process, intensity is high, rigidity is big, stability is good, and the utility model can be wanted according to client
Ask, its electromagnetic screen is adjusted by the foil thickness and the honeycomb length of side of the pattern, the thickness of panel 1, honeycomb core 2 that change copper mesh 4
Covering property.
It is described above, the only preferred embodiment of the utility model, when the utility model practical range can not be limited,
It is i.e. all to make equivalent changes and modifications according to the application scope, all should still it belong in the utility model covering scope.
