Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a shielding structure, which specifically includes a first shielding fin 1, a conductive foam 3 and a second shielding fin 2, the first shielding fin 1 and the second shielding fin 2 are both circumferential Formed between the opening gap 5 of the inner shielding space 4 to the outside, the second shielding fin 2 is arranged on the side close to the inner shielding space 4 relative to the first shielding fin 1, and the conductive foam 3 is arranged on the side of the inner shielding space 4 between the first shielding fin 1 and the second shielding fin 2;

[0033] Wherein, the inner surface of one side of the first shielding fin 1 is at least partially attached to one side of the conductive foam 3, and the end portion of the other side of the first shielding fin 1 and the inner shielding space 4 seal;

[0034] The outer surface of one side of the second shielding fin 2 is at least partially attached to the othe...

Embodiment 2

[0043] On the basis of Example 1, such as figure 2 As shown, a third shielding fin 6 is provided on the side of the second shielding fin 2 close to the inner shielding space 4, and the third shielding fin 6 and the second shielding fin 2 are respectively connected to the inner shielding space 4. The sealing position between the shielded spaces 4 is on the opposite side.

[0044] The positions of the first shielding fin 1, the second shielding fin 2 and the third shielding fin 6 at the opening gap 5 are arranged in a staggered relationship, and the third shielding fin 6 and the first shielding fin 1 are respectively connected to the inner shielding space 4. The sealing position is on the same side; after the opening slit 5 is closed, the first shielding fin 1, the second shielding fin 2 and the third shielding fin 6 form a curved structure that can weaken electromagnetic signals, and further improve the sealing performance of the conductive foam 3 Effective shielding of the i...

Embodiment 3

[0047] Based on Example 1, such as image 3 As shown, the present invention provides a cabinet electronic device, including a cabinet 7 and a door 8, and the shielding structure is arranged at the closed connection between the cabinet 7 and the door 8; wherein, the first One end of a shielding fin 1 is sealed and connected to the cabinet body 7 , and one end of the second shielding fin 2 is sealed and connected to the door body 8 . In order to facilitate the switching action, the end of the joint of the second shielding fin 2 and the conductive foam 3 can choose a rounded arc surface or a chamfered arc surface.

[0048]In a specific embodiment, the end of the conductive foam 3 is fixedly connected to the cabinet body 7 .

[0049] During the closing action of the cabinet body 7 and the door body 8 of the cabinet electronic equipment, because the shielding structure is designed to slide sideways, the resistance during the opening and closing process is reduced, and the shieldin...

Abstract

The invention provides a shielding structure and cabinet electronic equipment, the shielding structure comprises a first shielding fin, conductive foam and a second shielding fin, and the first shielding fin and the second shielding fin are circumferentially formed in an outward opening gap of an inner shielding space. The second shielding fin is arranged close to one side of the inner shielding space relative to the first shielding fin, and the conductive foam is arranged between the first shielding fin and the second shielding fin; wherein the inner surface of one side of the first shielding fin is at least partially attached to one side of the conductive foam, and the end part of the other side of the first shielding fin and the inner shielding space are sealed; the outer surface of one side of the second shielding fin is at least partially attached to the other side of the conductive foam, and the end of the other side of the second shielding fin and the inner shielding space are sealed. The electromagnetic shielding device can be popularized and applied to shielding of door and window mechanisms which are frequently opened and closed, electromagnetic signals are effectively shielded, and door opening and closing resistance is reduced.

Description

technical field [0001] The invention relates to the field of electromagnetic shielding, in particular to a shielding structure and cabinet electronic equipment, which are used for shielding the inner space. Background technique [0002] Electromagnetic shielding is a technology that needs to be solved in many electromechanical equipment, especially in the field of relatively high requirements for electromagnetic shielding. The traditional shielding method in electromechanical equipment is to install conductive foam at the door and window switches of electromechanical equipment, and through the conductive foam in the When the equipment is closed, it is in contact with the metal of the electromechanical equipment to achieve the shielding effect, and it is required that the surface of the electromechanical equipment in contact with the conductive foam must be metal, and the non-conductive layer cannot be sprayed. In addition, this shielding structure requires tight contact, and ...
