Abstract
The utility model discloses a glued board with an electromagnetic shielding lapping structure internally, which comprises a plurality of wood layers, wherein a shielding layer is arranged between at least two adjacent wood layers, lapping strips formed by tinsels are evenly arranged at the periphery of the shielding layer, the upper surface and the lower surface of the lapping strips are respectively and fixedly bonded with wood layers arranged above and below the lapping strips, and the length of each lapping strip is the same with that of a side edge where the lapping strip is arranged and is electrically connected with the shielding layer in the full length range. After the lapping strips are arranged at the periphery of the shielding layers of the glued board, when every two adjacent glued boards are assembled and connected, only mutual lapping strips are needed to be lapped and connected mutually in the full length range, therefore, not only the connection of the shielding layers of two glued boards are convenient, but also the integrality of a shielding body formed by the connection of the shielding layers can be ensured.
Description
Technical field
The utility model relates to the glued board that a kind of inside is provided with electro-magnetic screen layer, especially a kind of glued board that has the electromagnetic shielding bridging arrangement.
Background technology
In order to solve electromagnetic radiation, people combine the electromagnetic shielding theory with the glued board technology of preparing, developed glued board with electro-magnetic screen function, but, research in the past focuses mostly on developing material, seldom relate to the practical application of electromagnetic screen plywood, if and in use have the slit between the electromagnetic screen plywood, shielding properties by the shield that constitutes of shielding glued board will descend greatly so, and electromagnetic screen plywood metal shield materials different from the past, can not adopt conventional welding, riveted joint, modes such as screw connect, therefore, the interconnection technique of research glued board in practical engineering application has great importance.
The utility model content
Problem at the prior art existence, the purpose of this invention is to provide a kind of glued board that has the electromagnetic shielding bridging arrangement, by the bridging arrangement of self, link to each other and to realize the connection of screen easily and reliably between two glued boards, thereby guarantee the screening effectiveness of whole shield.
For achieving the above object, the glued board that the utility model inside has the electromagnetic shielding bridging arrangement comprises the several layers layer of wood, wherein be provided with screen between at least one pair of adjacent layer of wood, edge at this screen, also be provided with the bonding jumper that constitutes by metal forming, the upper and lower surface of this bonding jumper is adhesively fixed with the layer of wood that is positioned at its upper and lower respectively, and the length of each bonding jumper is all identical with the length of its place side and be electrically connected with screen in length range.
Further, the bonding jumper of described screen surrounding interconnects, and forms a sealed whole body bonding jumper.
Further, described bonding jumper is made by Copper Foil, or is made by aluminium foil.
After the edge of glued board screen is provided with bonding jumper, when adjacent two glued boards connect in assembling, only bonding jumper separately need be overlapped connection mutually in length range gets final product, therefore, the not only connection of convenient two glued board screens, and the integrality of the shield that is constituted after the connection of assurance screen.
Description of drawings
Fig. 1 is the utility model laminated structure schematic diagram;
Fig. 2 is the utility model glued board overlap joint connection status schematic diagram;
Fig. 3 is the utility model glued board right angle overlap joint connected mode schematic diagram.
Embodiment
Figure 1 shows that three layers of glued board, be provided with two-layer screen 2 between three layers of layer of wood 1, the edge of each screen 2 is provided with the bonding jumper of being made by metal forming 3, the length of every edge lap bar 3 is identical with this edge lengths of screen, and is electrically connected with screen at four corner.
It is the quadrangle shape of a sealing that the bonding jumper 3 of screen periphery can be made into integration.
Bonding jumper 3 can be made of Copper Foil, also can adopt aluminium foil to make, or is made by other proper metal paper tinsels.
The upper and lower surface of bonding jumper 3 is gluedd joint fixing with the layer of wood that is positioned at its upper and lower respectively.
As shown in Figure 2, when above-mentioned glued board connects at overlap joint, at first make the glued board edge stepped, make every layer of bonding jumper 3 parts expose out, then the exposed bonding jumper 3 of two glued board parts is overlapped mutually, realize being electrically connected, and then utilize conventional means that two glued boards are interfixed.
Need to prove that because of the bonding jumper in Fig. 1 glued board 3 is made by very thin Copper Foil or aluminium foil, when connecting in mode shown in Figure 2, two glued boards still keep the state that flushes basically, and just drawing for convenience shown in Figure 2.
As shown in Figure 3, when two glued boards vertically connect, will link to each other with bonding jumper 3 on another piece glued board again after bonding jumper 3 bendings on glued board wherein.
Claims (3)
1. the inner glued board that has the electromagnetic shielding bridging arrangement, this glued board comprises the several layers layer of wood, wherein be provided with screen between at least one pair of adjacent layer of wood, it is characterized in that, edge at described screen, also be provided with the bonding jumper that is made of metal forming, the upper and lower surface of this bonding jumper is adhesively fixed with the layer of wood that is positioned at its upper and lower respectively, and the length of each bonding jumper is all identical with the length of its place side and be electrically connected with screen in length range.
2. the glued board that has the electromagnetic shielding bridging arrangement as claimed in claim 1 is characterized in that, the bonding jumper of described screen surrounding interconnects, and forms a sealed whole body bonding jumper.
3. the glued board that has the electromagnetic shielding bridging arrangement as claimed in claim 1 is characterized in that described bonding jumper is made by Copper Foil, or is made by aluminium foil.
