Description

Technical Field

[0001] The utility model relates to an electromagnetic shield, in particular to an electromagnetic shielding metal spring used for shielding a machine room, belonging to the technical field of electromagnetic shielding. Background Art

[0002] Metal reeds have excellent mechanical properties, electrical conductivity, and plasticity, and are therefore widely used in gap filling designs for communications, computers, shielded rooms, shielded cabins, and other equipment. Metal reeds can not only solve the problem that other gasket materials cannot withstand tangential movement, but also maintain good shielding effectiveness over a wide frequency band. At the same time, metal reeds also have the characteristics of high thermal conductivity and good pressure resistance.

[0003] However, existing metal reeds still have certain problems. For example, in a metal reed for electromagnetic shielding disclosed in publication number CN215345499U, although a conductive elastic sealing gasket and a clamp-type mounting fixture are provided to enable sealed installation on uneven chassis surfaces, most current metal reeds adopt an integrated structure and are mostly long and narrow. Therefore, during installation, their length is often not suitable for different installation environments. Therefore, they need to be cut or assembled according to actual conditions. However, current metal reeds do not have a splicing structure. Therefore, when assembled, a certain gap will exist between two adjacent metal reeds, resulting in a significant reduction in their shielding performance. Utility Model Content

[0004] The technical solution of the present utility model addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. Specifically, the purpose of the present utility model is to solve the above-mentioned shortcomings in the existing technology and propose an electromagnetic shielding metal spring for shielding machine rooms.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An electromagnetic shielding metal spring for use in a shielded machine room, comprising a spring body, a mounting slot, an abutting spring, and a combination mechanism. The mounting slot is provided through the spring body and has a rectangular structure. One end of the abutting spring is fixed to one side of the mounting slot, and the other end is slidably connected to the mounting slot. The combination mechanism is provided around the spring body.

[0007] The combination mechanism includes a first docking portion, a clamping block and a clamping slot. The first docking portion is fixed to the front and rear sides of the spring body and is symmetrically arranged. The clamping block is fixed to one of the first docking portions, and the clamping slot is arranged on the other first docking portion, and the clamping block is clamped in the clamping slot.

[0010] As a further solution of the present invention: limiting springs are provided on the upper and lower sides of the edge of the installation slot, a clamping spring is provided at one end of the abutting spring, and the clamping spring is slidably clamped between the upper and lower limiting springs.

[0011] As a further solution of the present invention: two abutting springs are symmetrically arranged on the upper and lower sides of the spring body, and both have an arc-shaped structure.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] like Figures 1 to 4 As shown, an electromagnetic shielding metal spring for use in a shielded machine room includes a spring body 1, a mounting slot 2, an abutting spring 3, and a combination mechanism 4. The mounting slot 2 is provided through the spring body 1 and has a rectangular structure. One end of the abutting spring 3 is fixed to one side of the mounting slot 2, and the other end is slidably connected to the mounting slot 2. The combination mechanism 4 is provided around the spring body 1.

[0022] The assembly mechanism 4 includes a first docking portion 41, a clamping block 42, and a clamping slot 43. The first docking portion 41 is fixed to the front and rear sides of the spring body 1 and is symmetrically arranged. The clamping block 42 is fixed to one of the first docking portions 41, and the clamping slot 43 is provided on the other first docking portion 41, and the clamping block 42 is clamped in the clamping slot 43.

[0023] The combination mechanism 4 also includes a second docking portion 44, a limiting hole 45 and a docking protrusion 46. The second docking portions 44 are symmetrically arranged on the left and right sides of the spring body 1, and are staggered up and down. The limiting hole 45 is set through one of the second docking portions 44, and the docking protrusion 46 is set on the other second docking portion 44. The docking protrusion 46 is clamped in the limiting hole 45.

[0024] In the present invention, the reed body 1 is provided as a single structure, and a plurality of reed bodies 1 with single structures are combined to form an integral metal reed, thereby making the metal reed as a whole have a wider range of applications, and can be disassembled and assembled under different needs. After the assembly, there is no gap between two adjacent reed bodies 1, avoiding the problem that the gap between the two adjacent metal reeds currently exists, resulting in a significant reduction in the shielding effect. At the same time, through the provision of the combining mechanism 4, the front and rear sides and the upper and lower sides of the single reed body 1 can be quickly disassembled and assembled, so that the length and width of the metal reed as a whole can be freely combined, with a wide range of applications and easy operation. Example 2

[0025] like Figures 1 to 4 As shown, in addition to all the technical features of the first embodiment, this embodiment also includes:

[0026] The blocks 42 and the slots 43 are both trapezoidal in structure, and two of each are provided. The two adjacent blocks 42 and slots 43 are staggered in position up and down. The staggered structure allows the two adjacent spring bodies 1 to be firmly locked to avoid separation during installation.

[0027] Limiting springs 5 are provided on the upper and lower sides of the edge of the mounting groove 2, and a clamping spring 6 is provided at one end of the abutting spring 3, and the clamping spring 6 is slidably clamped between the upper and lower limiting springs 5. The abutting spring 3 is limited by the limiting spring 5, so that the abutting spring 3 can slide along a predetermined route when deformation occurs.

[0028] Two abutting springs 3 are symmetrically provided on the upper and lower sides of the spring body 1, and both are arc-shaped structures. By providing two abutting springs 3, the tightness of the spring body 1 installed in the gap is effectively improved to avoid loosening.

[0029] A supporting spring 7 is fixed between the upper and lower abutting springs 3. There are at least two supporting springs 7 symmetrically arranged. The supporting spring 7 supports the abutting spring 3 to prevent the elasticity of the abutting spring 3 from disappearing, which causes the metal spring to be unable to be firmly installed in the gap.

[0030] Working principle: When using the electromagnetic shielding spring, first assemble the spring body 1 according to actual usage requirements. During assembly, if the length is insufficient, the block 42 of the first docking portion 41 on the two adjacent spring bodies 1 is clamped with the card slot 43, so that the two adjacent spring bodies 1 can be quickly combined to form a metal spring as a whole. Repeat this operation until the predetermined length is reached. If the width is insufficient, the docking protrusion 46 of the second docking portion 44 of the two adjacent spring bodies 1 is clamped with the limiting hole 45. Repeat this operation until the predetermined width is reached. During installation, the metal spring as a whole composed of multiple spring bodies 1 is clamped in the gap that needs to be filled. During filling, the abutting spring 3 is deformed by the extrusion force, and simultaneously drives the supporting spring 7 to deform until it is completely clamped with the gap.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
