Problems solved by technology

[0004] 2. The spectrum is dense, and the spectrum of a large number of electronic equipment is mainly concentrated in 9kHz ~ 40GHz;
[0005] 3. The density and integration of equipment or systems are greatly increased, making it impossible to use many effective methods such as space isolation and layout that can be used in equipment or systems with small volume and space limitations;
[0006] 4. The sensitivity of the receiving equipment and system is improved, which greatly weakens its anti-interference ability;
[0007] 5. The transmission power of high-power transmitting equipment increases, resulting in increased interference to other equipment or systems;

Embodiment 1

[0029] Embodiment 1 It at least includes a door frame, a metal enclosure 1, a locking mechanism connected to the door body, a beryllium bronze reed, and a shielding groove. It is characterized in that: its door body, door frame, and locking mechanism are shielding structures, and the door The middle part of the body is fixed with a locking mechanism with a door handle 6. The locking mechanism is a door-through linkage type, that is, there are door handles 6 on both sides of the door, and the door can be opened with the door handle 6 both inside and outside the door. Both ends of the inner ring are fixed with 360° beryllium bronze reeds 16 and connected with the locking mechanism; the door frame is a metal enclosure 1 with shielding grooves 17 on the four sides, and the left and right sides of the shielding groove 17 are bonded with beryllium bronze reeds 16, The 16 arc-shaped tops of the left and right sides of the beryllium bronze reed after bonding are in close contact with e...

Embodiment 2

[0030] Example 2 as figure 1 , figure 2 with image 3As shown, the metal enclosure 1 is welded and connected to the outer surface of the wall after opening holes according to the size of the metal enclosure 1 on the shelter or the shielding wall, and the upper and lower ends of the outer side of the metal enclosure 1 are respectively fixed with locking pieces 8 , the locking piece 8 has a locking slot 12, and the door lock is embedded outside the locking slot 12; the metal enclosure 1 has shielding grooves 17 on the four sides, and the left and right sides of the shielding groove 17 are bonded with beryllium bronze reeds 16 After bonding, the arc-shaped tops of the beryllium bronze reeds 16 on the left and right sides are in close contact, and there is an insulating rubber sealing gasket 14 in the groove of the outer ring of the metal enclosure 1; the aluminum profile 15 of the door frame is plated with nickel-phosphorus alloy and The two sides of the shielding groove 17 ar...

Abstract

The invention discloses a structure of a broadband high shield effectiveness electromagnetic shielding door and a design method thereof. The structure of the electromagnetic shielding door adopts a 'single-tool three-spring' shielding structure, a metal plugboard and beryllium bronze reeds are in close pressing welding, meanwhile, the periphery in a metal surrounding frame is fully welded with metal bosses with inclination, and the beryllium bronze reed are spliced on the periphery of a door sectional material; when the shielding door is closed, the beryllium bronze reed can be in close pressing welding with the metal bosses with the inclination, thereby forming a two-loop 360 degrees shielding structure, the periphery of the shielding door is provided with two-loop metal plugboards, when the shielding door is closed, the whole shielding efficacy of the shielding door is greatly improved through close contact of one-loop metal plugboard and the beryllium bronze reeds; and the other loop metal plugboard is in close pressing welding with an insulation seal liner on the metal surrounding frame, thereby playing the role of a rain-proof moistureproof function, and effectively preventing an interior metal structure and one-loop plugboard and the beryllium bronze reeds from oxygenation.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic shielding of electronic shelter doors and shielding room doors, in particular to a structure and design method of a broadband high shielding efficiency electromagnetic shielding door, and relates to an electromagnetic leakage suppression method of electronic shelter doors and shielding room doors. Background technique [0002] At present, with the development of modern military electronic technology, the electromagnetic environment in which military electronic equipment is located reflects the following characteristics: [0003] 1.
