Problems solved by technology

However, no matter which type it is, there is always a fit gap between the various components of the shielding structure (for example, between the door knife and the beryllium copper reed, between the door knife and the shielding gasket), and the electromagnetic interference of the door There are also requirements for the complexity of the shielding structure, so it is difficult to achieve high shielding effectiveness through limited structural combinations, and usually only meet the B-level requirements of the national confidentiality standard GGBB1-1999
[0003] In addition, there is also the purpose of reducing electromagnetic leakage by pressing the shielding members against each other, thereby reducing the fit gap, such as figure 1 As shown, the electromagnetic shielding structure of such a door includes a bracket 20 and a door

Embodiment Construction

[0024] Embodiments of the electromagnetic shielding structure for doors according to the present invention will be described in detail below with reference to the accompanying drawings. In the following, "outer" and "inner" are relative to the shielding body, the part closer to the shielding body is called "inner", and vice versa is called "outer".

[0025] figure 2 is a schematic diagram of an electromagnetic shielding structure of a door according to an embodiment of the present invention, wherein the door is in an open state. In order to prevent the electromagnetic wave in the shield from leaking from the door gap, a plug-in 100 is arranged around the edge of the door body 10. Correspondingly, a socket 200 is provided at the edge of the shield 20. When the door is closed, the plug-in 100 is inserted into the socket 200, thereby Seal the door gap to achieve electromagnetic shielding effect. The structure of the plug-in 100 and the socket 200 will be described in detail be...

Abstract

The invention discloses an electromagnetic shielding structure used for a door, comprising a plug (100) which is fixed on the door body and a socket (200) which is fixed on the shielding body; the plug comprises a door cutter (110), a door bracket (120) and a metal reed (130) which is arranged on the door bracket; the socket comprises an internal insertion cutter (210), a middle bracket (220) and an external bracket (230); the middle bracket and the external bracket are provided with metal reeds (221 and 223) which push through each other correspondingly; a bypass passage (211) is formed between the middle bracket and the internal bracket; the end of the passage is provided with a chamber (213); wherein, the door cutter (110) is inserted into the metal reeds (221 and 223) which push through each other and are arranged between the middle bracket and the external bracket when the door is being closed; the internal side of the internal insertion cutter (210) is closely contacted with the metal reed (130) of the door bracket, thus gaining high shielding effect and leading the door to be easy to open and close at the same time.

Description

technical field [0001] The invention relates to an electromagnetic shielding structure of a door on an electromagnetic shielding device. Background technique [0002] Electromagnetic shielding doors are used on shielding bodies such as electromagnetic shielding boxes and shielding cabinets to seal the openings on the shielding body and prevent electromagnetic waves from leaking out. At present, the electromagnetic shielding structure of the door is roughly divided into three types. The first type is the structure in which the door blade and the beryllium copper reed are in close contact. The second type is that the door blade, bracket or similar is pressed against the shielding liner. Tight structure, there is also a combination of the aforementioned two structures, such as the disclosed "protective equipment door seam electric sealing structure" in the notification number CN2549145, which is exactly this type. In this type of combination, electromagnetic waves are sealed b...
