Description

An electromagnetic shielding device and a power cabinet Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to an electromagnetic shielding device and a power cabinet. Background Technology

[0002] Currently, in order to prevent the electromagnetic energy generated by the cables from being transmitted to the outside, power cabinets usually have a metal plate and a shielding component on the metal plate inside the cabinet. When shielding the cables, a metal stuffing box is installed on the metal plate for the cables to pass through.

[0003] In related technologies, in order to pass the cable through the metal stuffing box, the user needs to guide the cable from the bottom outside the power cabinet to the bottom inside the power cabinet, and then pass the cable through the metal stuffing box. Since the space at the bottom inside the power cabinet is small and close to the ground, and the inner diameter of the metal stuffing box is small, it is inconvenient for the user to operate and reduces the efficiency of cable passing.

[0033] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0034] As shown in Figures 1 to 6, this utility model provides an electromagnetic shielding device, including a receiving member 10, having a first side 11 and a second side 12 arranged opposite to each other, and at least one operating port 13 penetrating the first side 11 and the second side 12. The operating port 13 is configured to allow a user's body part to pass from the first side 11 to the second side 12 and grasp a cable 20 located on the second side 12. The cable 20 located on the second side 12 can pass through the operating port 13 and be located on the first side 11. A shielding component 30 is located on the first side 11 and covers the operating port 13. The shielding component 30 has a wire-passing hole 31, which is configured to allow the cable 20 located on the first side 11 to pass through and clamp and fix the cable 20. The shielding component 30 is used to electromagnetically shield the cable 20. When the cable 20 passes through the operating port 13 from the second side 12 and is located on the first side 11, the shielding component 30 is sleeved on the outer periphery of the cable 20 located on the first side 11 through the wire-passing hole 31 and covers the operating port 13.

[0035] In this embodiment, the receiving component 10 is specifically a metal plate, and the shielding component 30 and the receiving component 10 are made of materials with different conductivity properties, such as copper or aluminum, as long as they can meet the conductivity requirements of the device.

[0036] Meanwhile, the cross-sectional shape of the operating port 13 is square. Of course, in other embodiments, the cross-sectional shape of the operating port 13 can also be circular or trapezoidal, etc. The specific setting should be selected according to the usage environment of the device, so as to improve the applicability and scope of application of the device.

[0037] The beneficial effects of this electromagnetic shielding device are as follows: Through the operating port 13 penetrating the first side 11 and the second side 12 of the receiving member 10, the user can directly insert their hand or arm from the first side 11 into the second side 12 and then grasp the cable 20, moving it from the second side 12 to the first side 11. This improves the efficiency of cable 20 penetration. The grasped cable 20 is then passed through the shielding component 30, and the shielding component 30 is placed over the operating port 13, so that the shielding component 30 provides electromagnetic shielding for the cable 20, meeting the shielding requirements of the cable 20. Thus, the user can grasp the cable 20 and connect it to the shielding component 30 without excessive twisting of their body, reducing the user's labor intensity.

[0038] As shown in Figures 1 to 6, optionally, the shielding assembly 30 includes: a first shielding member 32, covering the operation port 13, the first shielding member 32 having a first arc-shaped opening 33 and a groove 34 disposed below and penetrating the first arc-shaped opening 33, the first arc-shaped opening 33 being disposed on the side wall of the first shielding member 32, the inner wall of the first arc-shaped opening 33 being connected to a portion of the groove wall of the groove 34 to form an arc-shaped wall adapted to the outer peripheral wall of the cable 20, the groove 34 being configured to allow the cable 20 to pass through; a second shielding member 35, covering the groove 34, the side wall of the second shielding member 35 having a second arc-shaped opening 36 adapted to the outer peripheral wall of the cable 20, the first arc-shaped opening 33 and the second arc-shaped opening 36 cooperating to form a wire passage hole 31, the second shielding member 35 being movable relative to the first shielding member 32 along the width direction of the first shielding member 32 to adjust the clamping force of the wire passage hole 31 on the cable 20.

[0039] In this embodiment, the width direction of the first shielding member 32 is X.

[0040] By setting the above structure, the cable 20 can be prevented from bending when passing through the shielding component 30 using the cable through hole 31, thereby avoiding damage to the structure of the cable 20 and extending the service life of the cable 20. At the same time, the second shielding component 35 can move relative to the first shielding component 32 in the width direction, so that the size of the cable through hole 31 and the clamping force can be adjusted according to the outer diameter of the cable 20 and actual needs. This allows the shielding component 30 to adapt to cables 20 with different outer diameter specifications, improving the versatility and practicality of the shielding component 30. It also reduces the gap between the cable through hole 31 and the cable 20, reduces the possibility of electromagnetic leakage, and enhances the shielding performance of the shielding component 30.

[0041] Meanwhile, the second shield 35 can move relative to the first shield 32, so when it is necessary to maintain or replace the cable 20, the shield assembly 30 can be more easily disassembled and installed, thereby improving the disassembly and assembly efficiency of the shield assembly 30.

[0042] Furthermore, the first shielding component 32 and the second shielding component 35 together constitute a multi-layer shielding structure, which can effectively block the transmission path of electromagnetic waves and improve the shielding effect of the shielding component 30.

[0043] In this embodiment, the first shielding member 32 and the second shielding member 35 are steel plates with a galvanized coating on their surface. Since zinc has higher metal activity than steel, it will preferentially undergo oxidation in humid or corrosive environments, thereby protecting the steel plate from corrosion. This helps to extend the service life of the steel plate. At the same time, the galvanized layer can serve as part of the electromagnetic shielding to reduce electromagnetic interference, thereby maximizing the shielding performance of the shielding device.

[0044] In other embodiments, the surfaces of the first shield 32 and the second shield may also be coated with a silver coating or a copper coating, as long as it can improve the shielding performance of the shielding device.

[0045] As shown in Figures 1 to 6, optionally, the first shielding member 32 includes a first connecting portion 321 and a second connecting portion 322 disposed on the surface of the first connecting portion 321, a groove 34 disposed on the first connecting portion 321, a first arc-shaped opening 33 disposed on the side wall of the second connecting portion 322, and a second shielding member 35 movably disposed on the surface of the first connecting portion 321; wherein, the first connecting portion 321 and the second connecting portion 322 are integrally formed structures.

[0046] By adopting an integral molding structure for the first connecting part 321 and the second connecting part 322, the gaps generated during their connection can be eliminated, thus significantly improving the shielding performance of the shielding assembly 30. Simultaneously, the integral molding structure can withstand greater external forces, reducing the risk of structural failure due to loosening or damage to the connecting parts.

[0047] As shown in Figures 4 to 6, optionally, the first shielding member 32 includes a plurality of first arc-shaped openings 33, at least two of the first arc-shaped openings 33 having different inner diameters; the second shielding member 35 includes a plurality of second arc-shaped openings 36, at least two of the second arc-shaped openings 36 having different inner diameters; wherein, the first arc-shaped openings 33 with different inner diameters and the second arc-shaped openings 36 with corresponding inner diameters cooperate with each other to form wire passage holes 31 with different inner diameters.

[0048] By setting the above structure, the wire through hole 31 with different inner diameters can adapt to the needs of wires 20 of different thicknesses, thus improving the versatility and practicality of the wire through hole 31.

[0049] Furthermore, the different inner diameters allow the gap between the cable hole 31 and the cable 20 to be minimized, reducing the possibility of electromagnetic signal leakage from the cable hole 31, thereby improving the overall shielding performance, effectively preventing electromagnetic interference from affecting the signal transmission of the cable 20, and ensuring the normal operation of the equipment.

[0050] The wire hole 31 in this embodiment has two inner diameters. Of course, in other embodiments, the inner diameter of the wire hole 31 can also be set to four or five, etc. The specific setting should be selected according to the usage environment of the device.

[0051] As shown in Figures 4 to 6, optionally, the side wall of the second connecting part 322 is also provided with a third arc-shaped opening 37, which is set to avoid the groove 34, and the side wall of the second shielding member 35 is also provided with an arc-shaped protrusion 38, which can be inserted and cooperate with the first arc-shaped opening 33 or the third arc-shaped opening 37.

[0052] This allows the arc-shaped protrusion 38 to close the first arc-shaped opening 33 or the third arc-shaped opening 37, thereby minimizing the gaps in the shielding assembly 30 and improving its shielding performance.

[0053] As shown in Figure 5, when a cable 20 needs to pass through a smaller inner diameter cable hole 31, the first arc-shaped opening 33 mates with the second arc-shaped opening 36, allowing the cable 20 to pass through. At this time, the third arc-shaped opening 37 mates with the arc-shaped protrusion 38.

[0054] As shown in Figure 6, when it is not necessary for the cable 20 to pass through the smaller inner diameter cable hole 31, the second shield 35 is rotated 180° and installed. At this time, the smaller inner diameter first arc-shaped opening 33 cooperates with the arc-shaped protrusion 38 to block the smaller inner diameter first arc-shaped opening 33.

[0055] Optionally, the receiving member 10 is provided with a plurality of fixing rods 40 extending along the second side 12 toward the first side 11. The plurality of fixing rods 40 are arranged circumferentially along the operating port 13. The first shielding member 32 has a plurality of connecting holes 41 that are aligned with the fixing rods 40. The fixing rods 40 pass through the corresponding connecting holes 41 to limit the position of the first shielding member 32 relative to the receiving member 10.

[0056] By setting up the above structure, during installation, it is only necessary to align the connecting hole 41 on the first shield 32 with the fixing rod 40 of the receiving part 10 and pass it through to complete the initial installation, saving installation time and labor costs. At the same time, since the fixing rod 40 and the connecting hole 41 are aligned, the first shield 32 can be positioned from multiple directions during the installation process, avoiding the first shield 32 from shifting or misaligning during the installation process, ensuring the accuracy and consistency of the installation, and facilitating the assembly of subsequent components and the stability of the overall structure.

[0057] In this embodiment, there are four connecting holes 41 and four fixing rods 40. Of course, in other embodiments, the number of connecting holes 41 and four fixing rods 40 can also be set to five or six, as long as the installation requirements of the first shielding component 32 can be met.

[0058] Optionally, the second shielding member 35 has a through-hole 42, which extends along the width direction of the first shielding member 32. The fixing rod 40 can pass through the connecting hole 41 and the through-hole 42 in sequence. The second shielding member 35 can move relative to the first shielding member 32 along the width direction of the first shielding member 32 through the through-hole 42.

[0059] In this embodiment, the portion of the fixing rod 40 protruding from the first shield 32 and the second shield 35 is threadedly connected by fasteners 80 to fix the first shield 32 and the second shield 35 onto the receiving member 10. This improves the tightness of the connection between the structures.

[0060] This allows for flexible adjustment of the relative positions of the two shielding components during installation and use, based on actual needs, to ensure a good fit between the cable hole 31 and the cable 20, and to improve the tightening effect on the cable 20.

[0061] Optionally, conductive foam 50 is wound around the outer peripheral wall of the cable 20, and the conductive foam 50 is used to fill the gap between the outer peripheral wall of the cable 20 and the wire hole 31.

[0062] Meanwhile, electromagnetic theory shows that when the receiver 10 receives high-frequency signals, the skin effect increases, and the gap effect of the receiver 10 is the main factor affecting electromagnetic shielding effectiveness. Taking necessary shielding measures for the gaps and openings on the receiver 10 can significantly improve its shielding effectiveness. Therefore, the gaps and openings between the cable 20 and the receiver 10 are key factors affecting the electromagnetic shielding effectiveness of the receiver 10. Improving the gap shielding effectiveness of the receiver 10 by setting the above-mentioned structures typically involves increasing the depth of the gaps, reducing the length of the gaps, reducing the spacing of the fastening points in the gaps, and enhancing the rigidity and surface finish of the substrate. Therefore, the above-mentioned setup can minimize the gap between the cable 20 and the through-hole 31, thereby improving the shielding effect.

[0063] Optionally, the electromagnetic shielding device also includes a base 60, with the receiving member 10 disposed on and fixedly connected to the base 60. In this embodiment, the base 60 is used to contact the ground, so placing the receiving member 10 on the base 60 can prevent the electromagnetic shielding device from directly contacting the ground and reducing the stability of the cable 20 during operation.

[0064] Secondly, this utility model provides a power cabinet 70, which includes the aforementioned electromagnetic shielding device.

[0065] The beneficial effects of the power cabinet 70 in this embodiment compared to the prior art are the same as those of the electromagnetic shielding device described above, and will not be repeated here.

[0066] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
