Description

Technical Field

[0001] This utility model relates to the field of server racks, and in particular to a shielded server rack. Background Technology

[0002] An electromagnetic shielding cabinet is a protective device that suppresses electromagnetic radiation through technologies such as shielding, isolation, and grounding. It is mainly used to prevent information leakage from electronic equipment. A common method is to install shielding strips on the cabinet door. However, the friction between the shielding strip and the cabinet body is relatively high, requiring considerable force to open or close the door, making it inconvenient to use. Furthermore, the electromagnetic shielding range provided by simply installing shielding strips on the cabinet door is limited. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the background technology by proposing a shielded cabinet. By adding multiple shielding strips, it can provide electromagnetic shielding over a wider range on all six sides of the cabinet. Furthermore, the friction between the shielding strips and the cabinet body is small, resulting in elastic contact. This improves the convenience of opening and closing the cabinet door while ensuring the shielding effect, making it more labor-saving.

[0004] The technical solution of this utility model is a shielded cabinet, including a cabinet body, a cabinet door, a frame, and a shielding strip; the cabinet body has a cubic structure, with an open front and four rectangular inner frames installed on the inner sides of the other five directions; the cabinet door is hinged to the front of the cabinet body, and four rectangular inner frames are installed on the inner side of the cabinet door; the frame has a cubic frame structure, and the frame is installed inside the cabinet body, forming compression spaces between the frame and the inner frames and the inner frames; the shielding strip is set on the periphery of the frame, and the shielding strip is deformed by the inner frames within the compression spaces.

[0005] Preferably, the shielding strip includes an integrally connected mounting plate and an elastic plate, with an acute angle between the mounting plate and the elastic plate, and the elastic plate is inclined toward the inside of the frame.

[0006] Preferably, the mounting plate has multiple mounting holes.

[0007] Preferably, multiple elastic plates are arranged side by side along the length of the mounting plate.

[0008] Preferably, there is a gap between two adjacent elastic sheet portions.

[0009] Preferably, the end of the elastic sheet portion away from the mounting sheet portion is bent inward.

[0010] Preferably, the connection between the mounting plate and the elastic plate is smoothly transitioned.

[0011] Preferably, a base is provided at the bottom of the cabinet.

[0012] Preferably, the cabinet door is equipped with a door lock.

[0013] Compared with existing technologies, this utility model has the following beneficial technical effects: By adding multiple shielding strips, this utility model can achieve a wider range of electromagnetic shielding on all six sides of the cabinet. Furthermore, the friction between the shielding strips and the cabinet body is low, resulting in elastic contact. This improves the convenience of opening and closing the cabinet door while ensuring the shielding effect, making it more labor-saving. The shielding strips are pre-installed on the frame. When the cabinet body is installed on the outer perimeter of the frame, the inner frame on the cabinet body compresses the shielding strips, deforming the elastic portion.

[0021] like Figures 1-6 As shown in the figure, the shielded cabinet proposed in this embodiment includes a cabinet body 1, a cabinet door 2, a frame 3, and a shielding strip 4.

[0022] Cabinet 1 has a cubic structure with an open front to accommodate cabinet doors 2. The other five sides of cabinet 1 (back, left, right, top, and bottom) each have four rectangular inner frames 11 installed on their inner sides. These inner frames 11 abut against the shielding strip 4. A base 5 is located at the bottom of cabinet 1, separating it from the ground.

[0023] Cabinet door 2 is hinged to the front of cabinet body 1. Four inner frames 21 arranged in a rectangle are installed on the inside of cabinet door 2. The inner frames 21 are used to abut against the shielding strip 4 when cabinet door 2 is closed. Cabinet door 2 is equipped with a door lock 6, which can be used to lock and unlock cabinet door 2.

[0024] like Figures 2-5As shown, frame 3 is a cubic frame structure, and frame 3 is installed inside cabinet 1. Extrusion spaces are formed between frame 3 and inner frame 11, and between frame 3 and inner frame 21, for compressing the shielding strip 4.

[0025] The shielding strip 4 is 0.1mm thick and made of copper-plated stainless steel. The shielding strip 4 is installed around the perimeter of the frame 3, with four shielding strips 4 installed in a rectangular pattern on each side of the frame 3. A total of 24 shielding strips 4 are pre-installed on the six sides of the frame 3, providing electromagnetic shielding from multiple directions and achieving good shielding effect. The shielding strip 4 is deformed by the inner frame 11 and inner frame 21 within the compression space.

[0026] like Figure 5 and Figure 6 As shown, the shielding strip 4 includes an integrally connected mounting plate portion 41 and an elastic plate portion 42, with an acute angle between the mounting plate portion 41 and the elastic plate portion 42. The elastic plate portion 42 is inclined towards the inside of the frame 3 and can be deformed by the inner frame. The mounting plate portion 41 is provided with a plurality of mounting holes 411 for mounting the shielding strip 4 onto the frame 3 through the mounting plate portion 41.

[0027] like Figure 6 As shown, multiple elastic sheet portions 42 are arranged side by side along the length of the mounting sheet portion 41, and are individually compressed and deformed from multiple points. There is a gap between adjacent elastic sheet portions 42, which makes it easier for elastic deformation and reset to occur, and avoids mutual interference in elastic deformation.

[0028] The end of the elastic piece 42 furthest from the mounting piece 41 bends inward. When the cabinet door 2 is closed, the inner frame 21 squeezes and deforms the elastic piece 42, specifically squeezing the part where the outer end of the elastic piece 42 bends inward. When the cabinet door 2 is opened, the inner frame 21 more easily disengages from this bent part, making it easier for the elastic piece 42 to elastically return to its original position. The connection between the mounting piece 41 and the elastic piece 42 is smoothly transitioned to avoid stress concentration, promoting smooth elastic deformation of the elastic piece 42 and extending its service life.

[0029] This embodiment adds multiple shielding strips 4, specifically a total of 24 shielding strips 4, which can provide a wider range of electromagnetic shielding on all six sides of the cabinet. The friction between the shielding strips 4 and the cabinet body 1 is low, resulting in elastic contact. This improves the convenience of opening and closing the cabinet door 2 while ensuring the shielding effect, making it more labor-saving. For the shielding strips 4 in the five positions other than the front of the cabinet body 1, these shielding strips 4 are pre-installed on the frame 3. When the cabinet body 1 is installed on the outer perimeter of the frame 3, the inner frame 11 on the cabinet body 1 compresses the shielding strips 4, deforming the elastic sheet portion 42.

[0030] This shielded cabinet meets Class C (FGWS-c1) of the national confidentiality standard BMB19-2006 "Technical Requirements and Test Methods for Electromagnetic Leakage Emission Shielded Cabinets", and can be used for electromagnetic protection to prevent the leakage of important information.

[0031] The shielding range of this shielded cabinet is as follows:

[0032] 1. Magnetic field: ≥70dB at 14kHz, ≥95dB at 150kHz;

[0033] 2. Microwave: 1GHz-10GHz ≥95dB;

[0034] 3. Plane wave: 50MHz-1GHz ≥100dB;

[0035] 4. Electric field: ≥100dB for 200kHz-50MHz.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
