Description

Technical Field

[0001] The utility model relates to the technical field of shielding square cabins, in particular to a waveguide wire passing device, a square cabin waveguide wire passing shielding structure and a shielding square cabin. Background Art

[0002] The electromagnetic shielding cabin is equipped with power supply, signal and other interface wall boxes for exchanging and transferring signals inside and outside the cabin. For the shielded cabin, to ensure shielding performance, the interface needs to be shielded accordingly. The principle is to set up a shielding cover, which is connected to the cabin skin through good conductive connection to form a Faraday cage to shield the signal. However, the cables connecting the inside and outside of the cabin must use filtering and cutoff waveguides to shield the conducted and radiated signals. In the existing technology, the power line is shielded by installing a power filter to eliminate interference. For the signal line, shielded cables are usually used to prevent radiated signals. However, due to the working condition that the signal transmission frequency of the signal line is not fixed, it is difficult to install a filter on the signal line. To solve the signal line shielding problem, the method of setting up a waveguide is usually used to solve it. The continuous reflection of the signal in the metal waveguide weakens the impact of the signal.

[0003] Usually, an input opening is set on the shielding cover inside the cabin. In order to accommodate all cables and connectors, the opening is generally large. Even if multiple openings are opened for a single cable to pass through, shielding leakage may still occur, which affects the shielding effect. Utility Model Content

[0026] The utility model provides a waveguide wire passing device, a square cabin waveguide wire passing shielding structure and a shielding square cabin. Figures 1 to 3 The utility model provides a specific embodiment of a waveguide wire passing device, a square cabin waveguide wire passing shielding structure and a shielding square cabin.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a waveguide wire-passing device 100, comprising a wire-passing component 1 that can be installed on a wall panel and a sealing adjustment component 2 for adjusting the wire-passing component 1 to achieve sealing, the sealing adjustment component 2 is connected to the wire-passing component 1, the wire-passing component 1 comprises a first metal shielding plate 11 and a second metal shielding plate 12, the first metal shielding plate 11 and the second metal shielding plate 12 are arranged relative to each other in the x-direction, and the first metal shielding plate 11 can be spliced and matched with the second metal shielding plate 12 to form a wire-passing hole group 13, the wire-passing hole group 13 includes a plurality of wire-passing holes 131 spaced apart in the y-direction for cables to pass through and fit the hole wall to achieve sealing.

[0028] In the present invention, the sealing adjustment component 2 is connected to the wire-passing component 1, and the wire-passing component 1 includes a first metal shielding plate 11 and a second metal shielding plate 12. The first metal shielding plate 11 and the second metal shielding plate 12 are arranged relative to each other in the x-direction, and the first metal shielding plate 11 can be spliced and matched with the second metal shielding plate 12 to form a wire-passing hole group 13. The wire-passing hole group 13 includes a plurality of wire-passing holes 131 spaced apart in the y-direction for cables to pass through and fit against the hole wall to achieve sealing. The operator divides the entire wiring harness into multiple cables, and each of the cables passes through the wall panel and the wire-passing hole 131 in sequence one by one. The cables are sealed and fixed through the wire-passing hole 131. Since the wire-passing component 1 is installed on the wall panel, multiple cables are installed and fixed on the wall panel. Compared with the existing wire-passing equipment that passes the entire wire harness through a larger opening in the wall panel, even if multiple smaller openings are opened for a single cable to pass through, shielding leakage still exists. On the one hand, the present application shields the cable by using the first metal shielding plate 11 and the second metal shielding plate 12 made of metal material. On the other hand, the sealing adjustment component 2 adjusts the distance between the first metal shielding plate 11 and the second metal shielding plate 12 to clamp and seal the cable to avoid shielding leakage and ensure the shielding effect.

[0029] It should be noted that the shape of the hole wall of the wire hole 131 is adapted to the shape of the outer surface of the cable, so that the first metal shielding plate 11 and the second metal shielding plate 12 can seal and fix the cable by means of matching clamping.

[0030] When the number of the cables is large, at least the same number of the wire holes 131 need to be opened. If only one wire hole group 13 is provided, the length of the first metal shielding plate 11 and the second metal shielding plate 12 will be too long, which will affect the structural strength of the first metal shielding plate 11 and the second metal shielding plate 12 on the one hand, and will be detrimental to the bundling of the cables on the other hand. Therefore, in some embodiments, such as Figure 1 and Figure 2 As shown, the plurality of wire guide assemblies 1 are provided, and the plurality of wire guide assemblies 1 are arranged along the x-direction. In this arrangement, by adding a plurality of wire guide assemblies 1, the number of wire guide hole groups 13 is increased, and the number of wire guide holes 131 is also increased, thereby allowing the waveguide wire guide device 100 to be installed and fixed with more cables.

[0031] Furthermore, in some embodiments, Figure 1 As shown, the wire-passing assemblies 1 are connected end to end in sequence. In this way, the plurality of wire-passing assemblies 1 form a whole, which reduces the space occupied by the wire-passing assemblies 1 on the one hand and improves the structural strength of the wire-passing assemblies 1 on the other hand.

[0032] Specifically, in some embodiments, the second metal shielding plate 12 of the wire passing assembly 1 and the first metal shielding plate 11 of the adjacent wire passing assembly 1 to which it is connected are integrally formed, so that the structural strength of the wire passing assembly 1 is higher.

[0033] The specific structure of the sealing adjustment component 2 is not limited, as long as the sealing adjustment component 2 can adjust the wire assembly 1 to achieve sealing. For example, in some embodiments, Figure 1 As shown, the seal adjustment assembly 2 includes a locking bolt 21. The first metal shielding plate 11 and the second metal shielding plate 12 have two adjustment holes defined in the x-direction, allowing the locking bolt 21 to pass through one of the adjustment holes and threadably connect with the other. This arrangement allows the distance between the first and second metal shielding plates 11, 12 to be adjusted by rotating the locking bolt 21, ensuring that the wall of the cable hole 131 is in contact with the outer surface of the cable, achieving a seal.

[0034] Since the first metal shielding plate 11 and the second metal shielding plate 12 are elastic, only one locking bolt 21 is provided, which results in a smaller distance between the two shielding plates at the connection point of the locking bolt 21 and a larger distance between the two ends of the shielding plates, resulting in the wire holes 131 at both ends of the shielding plates being unable to be completely sealed. Therefore, in some embodiments, Figure 2 As shown, there are multiple locking bolts, which are spaced apart in the y-direction, and each wire hole is located between two adjacent locking bolts. This arrangement allows the hole wall of each wire hole 131 to completely fit the outer surface of the cable to achieve a seal, thereby improving the shielding effect.

[0035] To achieve better shielding, in some embodiments, the inner wall of the cable hole 131 is covered with a metal shielding layer. This allows the metal shielding layer to cover the cable's wire section when it passes through the hole 131, further preventing shielding leakage. Specifically, the metal shielding layer is a double-layer copper mesh.

[0036] In addition, if Figure 3 As shown, the present invention also provides a square cabin waveguide wire shielding structure 1000, including a square cabin wall panel 200, an adapter panel 300 and the waveguide wire passing device 100, the adapter panel 300 is installed on the outer side of the square cabin wall panel 200, the waveguide wire passing device 100 is installed on the inner side of the square cabin wall panel 200, the adapter panel 300 has a mounting surface for cable connection, and a plurality of through holes are opened on the square cabin wall panel 200 for the cables to pass through the through holes and the wire passing holes 131 in sequence.

[0037] Furthermore, in some embodiments, Figure 3 As shown, the cubicle waveguide shielding structure 1000 further includes a first housing 400, which is mounted on the outside of the cubicle wall panel 200. The adapter panel 300 is disposed within the first housing 400. With this arrangement, since the adapter panel 300 is located outside the cubicle wall panel 200 and may be damaged, the first housing 400 is provided and placed within the first housing 400 to protect the adapter panel 300. Specifically, because the adapter panel 300 needs to be connected to the circuits of an external device, a first opening is defined at one end of the first housing 400 to expose the adapter panel 300. A first cover 410 is hingedly connected to one side of the first housing 400, and the first cover 410 is configured to cover the first opening.

[0038] Since the cables extend into the shielding cabin through the waveguide wire passing device 100 and are electrically connected to the equipment in the shielding cabin, in order to prevent the cables from being scattered around in the shielding cabin, in some embodiments, such as Figure 3 As shown, the shelter waveguide wire shielding structure 1000 also includes a second housing 500. The second housing 500 is mounted on the inner side of the shelter wall panel 200 and has a storage cavity. The waveguide wire passing device 100 is located within the storage cavity. The side of the housing is provided with a cable outlet 510 connected to the storage cavity, through which the cable bundle is extended. This arrangement allows the second housing 500 to accommodate scattered cables and allows the cable bundle to extend through the cable outlet 510, preventing the cables from being scattered and affecting the movement of people in the shielded shelter.

[0039] It should be noted that when the number of cables to be fixed is small, the volume of the waveguide passing device 100 is small. At this time, the waveguide passing device 100 can be arranged on the side of the second shell 500 to reduce the volume of the second shell 500.

[0040] Furthermore, when the cable fails, in order to facilitate maintenance by maintenance personnel, a second opening is opened at one end of the second shell 500, and a second cover 520 is hinged on one side of the second shell 500, and the second cover 520 covers the second opening.

[0041] In addition, the present invention also provides a shielding cabin, including the cabin waveguide wire shielding structure 1000.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
