Description

Technical Field

[0001] This application relates to the field of electromagnetic shielding window technology, and in particular to a military-grade shielded, waterproof, and breathable waveguide window. Background Technology

[0002] In conventional equipment, balancing the pressure difference between the inside and outside of the equipment requires opening windows or holes to allow air convection between the inside of the equipment and the external environment. Military products, on top of this, also require that the equipment meet the relevant requirements of electromagnetic compatibility, that is, the equipment will not fail or degrade in performance due to electromagnetic interference from the external environment, and at the same time, the internal information of the equipment will not be leaked.

[0003] Currently, conventional military equipment uses honeycomb waveguides for ventilation and shielding. However, honeycomb waveguides can only serve a shielding function and cannot meet the environmental sealing requirements of military equipment, such as waterproofing and dustproofing, thus limiting their application. Utility Model Content

[0004] In order to improve the problem that existing honeycomb waveguide panels cannot meet the requirements of military waterproofing and dustproofing, this application provides a military shielded waterproof and breathable waveguide window.

[0006] A military-grade shielded, waterproof, and breathable waveguide window includes a conductive rubber pad, a honeycomb waveguide plate, a waterproof and breathable membrane, and a dust filter arranged sequentially from the inside to the outside. The outer frame of the honeycomb waveguide plate has multiple mounting holes for fasteners to pass through.

[0007] Furthermore, the conductive rubber pad is arranged around the outer frame of the honeycomb waveguide plate.

[0008] Furthermore, a pressure frame is provided on the side of the dust filter facing away from the honeycomb waveguide plate, and the pressure frame is provided with a plurality of through holes corresponding one-to-one with the plurality of mounting holes.

[0009] Furthermore, the waterproof and breathable membrane is provided with sealing rubber gaskets on both sides near the pressure frame and the honeycomb waveguide plate.

[0010] Furthermore, the sealing rubber gasket is the same width as the outer frame of the honeycomb waveguide plate.

[0011] Furthermore, the sealing rubber gasket is made of silicone rubber.

[0012] Furthermore, the dust filter is made of stainless steel or nickel-plated aluminum alloy, and its mesh count is no greater than 40 mesh.

[0013] Furthermore, the inner core of the honeycomb waveguide plate is made of stainless steel, and the outer frame is made of stainless steel or nickel-plated aluminum alloy.

[0014] Furthermore, the core aperture of the honeycomb waveguide plate is one of 1.6mm, 2.5mm or 3.2mm.

[0015] Furthermore, the pressure frame has multiple countersunk holes on the side opposite to the honeycomb waveguide plate, each corresponding to one of the multiple perforations.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The conductive rubber pads provide electromagnetic shielding and environmental sealing for the installation gaps; the honeycomb waveguide plate provides electromagnetic shielding for the ventilation openings; the waterproof and breathable membrane provides waterproofing and dustproofing for the ventilation openings; and the dust filter filters out larger impurities such as branches and leaves and protects the waterproof and breathable membrane. The military-grade shielded waterproof and breathable waveguide window of this application requires only the removal of screws and cleaning or replacement of the waterproof and breathable membrane for maintenance and repair, making maintenance more convenient.

[0018] 2. The double-layer sealing rubber pads on both sides of the waterproof and breathable membrane can provide good protection for the edges of the membrane, effectively resisting impact and vibration, and ensuring its service life. The sealing rubber pads made of silicone rubber can resist mold, salt spray, acid and alkali, high and low temperature, and humid heat, which is suitable for extending the service life of the military shielded waterproof and breathable waveguide window of this application in harsh environments.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a military-grade shielded, waterproof, and breathable waveguide window, which includes a conductive rubber pad 1, a honeycomb waveguide plate 2, a waterproof and breathable membrane 3, and a dust filter 41 arranged sequentially from the inside to the outside. The outer frame of the honeycomb waveguide plate 2 has multiple mounting holes 21 for fasteners to pass through, such as screws. Specifically, the conductive rubber is made by uniformly distributing conductive particles such as silver-plated glass, silver-plated aluminum, and silver in silicone rubber, and applying pressure to bring the conductive particles into contact, achieving good conductivity.

[0032] The conductive rubber pad 1 surrounds the outer frame of the honeycomb waveguide plate 2 and is the same width as the outer frame. The dust filter 41 is made of stainless steel or nickel-plated aluminum alloy with a mesh size of no more than 40 mesh. The inner core of the honeycomb waveguide plate 2 is made of stainless steel, and the outer frame is made of stainless steel or nickel-plated aluminum alloy. The inner core aperture of the honeycomb waveguide plate 2 is one of 1.6mm, 2.5mm, or 3.2mm. Specifically, if the waveguide window has design requirements for weight reduction, the outer frame of the honeycomb waveguide plate 2 is made of nickel-plated aluminum alloy, and the dust filter 41 is also made of nickel-plated aluminum alloy. When selecting the inner core aperture of the honeycomb waveguide plate 2, the principle of larger aperture, lower shielding effectiveness, and greater ventilation volume is followed, and the selection can be made according to actual usage requirements.

[0033] Therefore, the conductive rubber pad 1 provides electromagnetic shielding and environmental sealing for the installation gaps, the honeycomb waveguide plate 2 provides electromagnetic shielding for the ventilation openings, the waterproof and breathable membrane 3 provides waterproofing and dustproofing for the ventilation openings, and the dust filter 41 filters out larger impurities such as branches and leaves and protects the waterproof and breathable membrane 3. The military-grade shielded waterproof and breathable waveguide window of this application requires only the removal of screws and cleaning or replacement of the waterproof and breathable membrane 3 for maintenance and repair, making maintenance more convenient.

[0034] Additionally, refer to Figure 1 , Figure 2 and Figure 3 A pressure frame 42 is provided on the side of the dust filter 41 facing away from the honeycomb waveguide plate 2. The pressure frame 42 has multiple through holes 421 corresponding to the multiple mounting holes 21, and multiple countersunk holes 422 corresponding to the multiple through holes 421 are opened on the side of the pressure frame 42 facing away from the honeycomb waveguide plate 2. The dust filter 41 can be set separately from the pressure frame 42, or the dust filter 41 can be welded to the pressure frame 42, which facilitates installation, maintenance and disassembly.

[0035] Furthermore, to prevent the waterproof and breathable membrane 3 from being torn due to impact and vibration from the equipment, refer to... Figure 3 and Figure 4 Sealing rubber pads 5 are provided on both sides of the waterproof and breathable membrane 3 near the pressure frame 42 and the honeycomb waveguide plate 2. The sealing rubber pads 5 are the same width as the outer frame of the honeycomb waveguide plate 2, and the sealing rubber pads 5 are made of silicone rubber.

[0036] In this way, the double-layer sealing rubber gasket 5 can provide good protection for the edge of the waterproof and breathable membrane 3, effectively resisting impact and vibration, and ensuring its service life; while the sealing rubber gasket 5 made of silicone rubber can resist mold, salt spray, acid and alkali, high and low temperature, and humid heat, which is suitable for extending the service life of the military shielded waterproof and breathable waveguide window of this application in harsh environments.

[0037] The implementation principle of a military-grade shielded, waterproof, and breathable waveguide window according to an embodiment of this application is as follows:

[0038] The conductive rubber pad 1 provides electromagnetic shielding and environmental sealing for the installation gaps, the honeycomb waveguide plate 2 provides electromagnetic shielding for the ventilation openings, the waterproof and breathable membrane 3 provides waterproofing and dustproofing for the ventilation openings, and the dust filter 41 filters out larger impurities such as branches and leaves and protects the waterproof and breathable membrane 3. Maintenance and repair of the military-grade shielded waterproof and breathable waveguide window of this application only require removing the screws and cleaning or replacing the waterproof and breathable membrane 3.

[0039] Furthermore, the double-layer sealing rubber pads 5 on both sides of the waterproof and breathable membrane 3 can provide good protection for the edge of the waterproof and breathable membrane 3, effectively resisting impact and vibration, and ensuring its service life. The sealing rubber pads 5 made of silicone rubber can resist mold, salt spray, acid and alkali, high and low temperature, and humid heat, which is suitable for extending the service life of the military shielded waterproof and breathable waveguide window of this application in harsh environments.
