Description
Technical field
This utility model is related to 60dB shelter shield technology field, particularly 60dB shelter power supply wall box.
Background technology
Domestic market gradually increases for the demand of shielding shelter, and capability of electromagnetic shielding is for civilian or military side
Cabin is all to have very important effect.
Shielding shelter mainly has two ways：Inside panel shielding, exterior skin shielding.The shelter of great majority shielding at present adopts
Mode is inside panel shielding, adopts interior aluminum corner brace to connect, to form a hexahedro shielding field between inside panel.But, inside shelter
Rack, equipment more, need to firmly install, reliable, be necessary for the backing plate of rack, equipment etc. and big intralaminar part is spirally connected or riveting
Connect, therefore the hole count on inside panel is also relatively more, is the latency causing leakage field.
Because shelter outer surface aperture, gap are more, rivet hole in especially outer aluminum corner brace, causes shield effectiveness to be extremely difficult to
Ideal indicator.Outer aluminum corner brace is connected with big plate using riveting method, and aluminum corner brace will be holed, flat to ensure aluminum corner brace installation strength and surface
Whole degree.In order to reach shield effectiveness, pitch-row will ensure that the linear gap length of aluminum corner brace, in certain scope, typically requires gap
Linear dimension be less than λ/10～λ/100.And it is also performed to water-proofing treatment between outer aluminum corner brace and big plate exterior skin, outside
Aluminum corner brace inner surface coats fluid sealant, and the metal seriality for aluminum corner brace and exterior skin has large effect.Hole therefore in aluminum corner brace,
Seam has on the capability of electromagnetic shielding of shelter obviously to be affected.
Electromagnetic shielding square cabin common at present can touch the mark as 40dB, and some Military Shelter require indexs to reach 60dB
Even more high, therefore with respect to the shielding construction of 40dB shelter, 60dB shelter then needs more preferable shield effectiveness, and on shelter not
Only its side seam needs to carry out structural change, and is additionally provided with miscellaneous part on shelter, such as power supply wall box, therefore it is required that its power supply
Wall box equally has very strong electric continuity.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides one kind to meet electric continuity, leakage field rate low
The 60dB shelter power supply wall box good with shield effectiveness.
The purpose of this utility model is achieved through the following technical solutions：60dB shelter power supply wall box, it includes inner cover, interior
Mask, wave filter installing plate and jack mounting plates, described jack mounting plates are provided with adapter input socket, adapter defeated
Go out socket, spark gap and ground stud socket, and the two ends of jack mounting plates are fixedly connected with wave filter installing plate, described filtering
Power supply and power-supply filter are provided with device installing plate, described inner cover is provided with adapter socket through walls, described inner cover
With the riveting of interior mask, and the first metallic gasket is installed between inner cover and interior mask, described interior mask is additionally provided with
The connecting plate of wave filter installing plate riveting, is provided with the second metallic gasket between connecting plate and wave filter installing plate.
Described inner cover is metallic shield or includes metallic shield net.
Described wave filter installing plate and jack mounting plates are surface oxidation treatment plate.
This utility model has advantages below：Shelter power supply wall box of the present utility model, by inner cover and the riveting of interior mask
And wave filter installing plate and the riveting of interior mask, and it is provided with corresponding first metallic gasket and the second metal gasket at riveting
Piece, the first metallic gasket ensure that the electric continuity of inner cover and interior mask, the second metallic gasket ensure that wave filter installing plate with
The electric continuity of interior mask, thus reducing the magnetic flux leakage from shelter power supply wall box for the electromagnetism, reducing leakage field rate, enhancing shielding
Effect, meets the performance requirement of 60dB shelter electromagnetic shielding.
Brief description
Fig. 1 is structural representation of the present utility model
In figure, 1- inner cover, mask in 2-, 3- wave filter installing plate, 4- first metallic gasket, 5- second metallic gasket, 6-
Power supply, 7- jack mounting plates, 8- power-supply filter, 9- adapter input socket, 10- adapter socket through walls, 11- connecting plate.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described, protection domain of the present utility model be not limited to
Lower described：
As shown in figure 1,60dB shelter power supply wall box, it includes inner cover 1, interior mask 2, wave filter installing plate 3 and socket peace
Dress plate 7, in the present embodiment, described wave filter installing plate 3 and jack mounting plates 7 are surface oxidation treatment plate, described
Jack mounting plates 7 on adapter input socket 9, adapter accessory power outlet, spark gap and ground stud socket are installed, and socket
The two ends of installing plate 7 are fixedly connected with wave filter installing plate 3, and described wave filter installing plate 3 is provided with power supply 6 and power supply filter
Ripple device 8, described inner cover 1 is provided with adapter socket through walls 10, and described inner cover 1 is riveted with interior mask 2, and in inner cover 1
And interior mask 2 between, the first metallic gasket 4 is installed, in the present embodiment, described inner cover 1 is metallic shield or includes
