Description

Technical Field

[0001] This application relates to the field of switch technology, and more specifically, to a dustproof and moisture-proof sealing device for communication switch ports. Background Technology

[0002] In modern communication networks, switches, as core devices for data transmission and switching, are widely used in various scenarios such as enterprise computer rooms, data centers, industrial control sites, and home networks. Their ports, as key interfaces connecting external devices (such as routers, servers, and terminal devices), directly affect the stability of communication links and data transmission efficiency. However, in actual use environments, switch ports often face the problem of dust and moisture corrosion. In computer rooms or data centers, although the overall environment is relatively clean, fine dust in the air can still gradually accumulate through port gaps during long-term operation, covering the surface of metal contacts and increasing contact resistance. This can lead to data transmission packet loss and delays, or even complete port communication interruption. In humid environments such as industrial control sites and basements, moisture in the air easily condenses inside the ports, accelerating the oxidation and corrosion of metal contacts and potentially causing short circuits, severely shortening the switch's lifespan, increasing equipment maintenance costs, and raising the risk of network failures.

[0003] Currently, protective measures for switch ports are relatively limited. Some switches only come with simple plastic dust covers at the factory, but these covers don't fit the ports well, making them ineffective at preventing moisture intrusion. Furthermore, they are easily lost during frequent plugging and unplugging of network cables, resulting in poor continuous protection. In some scenarios, insulating tape is used for sealing, but this method is cumbersome, and the sealing performance deteriorates sharply after repeated disassembly. Additionally, residual adhesive from the tape can contaminate the ports, further affecting connection reliability.

[0004] Therefore, in order to address the shortcomings of existing protective measures in terms of dust and moisture protection, ease of use, and continuous protection, it is urgent to develop a sealing device that can fit tightly to the switch port, effectively block dust and moisture, and is easy to install and disassemble, to ensure the long-term stable operation of the switch port. Utility Model Content

[0005] The dustproof and moisture-proof sealing device for the communication switch port provided in this application adopts the following technical solution: A dustproof and moisture-proof sealing device for a communication switch port includes a switch body. A sealing cover is installed at the tail end of the switch body, and a mounting foot is welded to the open end of the sealing cover. The surface of the mounting foot is fixedly connected to the outer shell of the switch body by quick-release screws. A filter assembly is connected to one side of the top surface of the sealing cover, and a dustproof mesh is embedded on the other side of the top surface of the sealing cover. A flange joint is welded to the top of the filter assembly, and an activated carbon filter is sealed at the connection between the filter assembly and the sealing cover. Several hollow cylinders are fixed to the top surface of the activated carbon filter, and each hollow cylinder is filled with desiccant. The top of each hollow cylinder abuts against the inner wall of the filter assembly. Several small square holes are opened in the middle of the end face of the sealing cover, and a large square hole is opened at the edge of the end face of the sealing cover.

[0006] The above technical solutions meet the requirements for dust and moisture protection of the switch's ports.

[0007] Furthermore, a line clip is inserted and installed inside the large square hole and several small square holes, and the line clip is composed of two separate T-shaped parts, and the two T-shaped parts of the line clip have tapered line clamping grooves on their facing surfaces.

[0008] The above technical solution enables the wiring to be installed through a loop and sealed.

[0009] Furthermore, two sets of plug-in sleeves are welded to the inner wall of the sealing cover, and a trapezoidal plug is inserted into each plug-in sleeve. One end of the trapezoidal plug contacts the edge of the bottom surface of the activated carbon filter, and the other end of the trapezoidal plug is provided with a magnet that is adsorbed and connected to the plug-in sleeve.

[0010] The above technical solution achieves the fixation of the activated carbon filter screen and meets the requirements for subsequent disassembly and maintenance.

[0011] Furthermore, the mounting feet are L-shaped, and a screw hole is provided at the end of the mounting feet that connects to the outer shell of the switch body.

[0012] The above technical solution facilitates the reliable installation of the sealing cover.

[0013] Furthermore, a loose column is fixed inside the hollow cylinder, and several conical discs are welded at equal intervals from top to bottom on the surface of the loose column, and the diameter of the conical discs of the loose column is smaller than the inner diameter of the hollow cylinder.

[0014] The above technical solutions increase the fluffiness of the desiccant and prevent it from piling up.

[0015] Furthermore, a dust baffle is provided on the surface of the sealing cover corresponding to the dustproof net, and a plurality of support pillars welded to the sealing cover are provided on the bottom surface of the dust baffle.

[0016] The above technical solutions facilitate dust prevention and extend the maintenance cycle.

[0017] Furthermore, a rubber sealing ring is bonded to the open end of the sealing cover, and the rubber sealing ring abuts against the tail end of the switch body.

[0018] The above technical solutions improve the sealing performance of the sealing cover installation.

[0019] In summary, this application includes the following beneficial technical effects: A filter assembly with a flange joint is installed on the sealed cover. The activated carbon filter and the desiccant filled in the hollow cylinder of the filter assembly are used. With the air outlet pipe of the external blower connected to the flange joint, the moisture and impurities in the outside air are adsorbed by the activated carbon filter and the desiccant in the hollow cylinder. The dustproof net serves as an air vent, which satisfies the requirement of drying and purification of air before it enters the sealed cover. This greatly reduces the risk of port failure caused by dust accumulation and moisture erosion. It also solves the heat dissipation problem at the tail end of the switch after the sealed cover is installed. Combined with the rubber sealing ring between the sealed cover and the tail end of the switch body, it solves the shortcomings of existing protection methods in dust and moisture prevention.

[0020] Furthermore, the split design of the wire clips facilitates wire insertion and removal, and maintains good sealing performance even after multiple operations, avoiding the sharp decline in sealing performance that occurs after repeated removal of insulating tape. The small and large square holes on the end face of the sealing cover, combined with the tapered wire clip grooves, can accommodate wires of different diameters, meeting various connection requirements. Together with the sealing of the wire penetration points by the wire clips, a comprehensive sealing system is constructed, effectively preventing the intrusion of external dust and moisture.

[0026] Example:

[0027] This application discloses a dustproof and moisture-proof sealing device for communication switch ports. Please refer to [link / reference]. Figure 1 and Figure 4The system includes a switch body 1, a sealing cover 2 installed at the rear end of the switch body 1, and mounting feet 3 welded to the open end of the sealing cover 2. The surfaces of the mounting feet 3 are fixedly connected to the outer shell of the switch body 1 by quick-release screws. A filter assembly 4 is connected to one side of the top surface of the sealing cover 2, and a dustproof mesh 5 is embedded on the other side of the top surface of the sealing cover 2. A flange joint 10 is welded to the top of the filter assembly 4, and an activated carbon filter 11 is sealed at the connection between the filter assembly 4 and the sealing cover 2. Several perforated cylinders 12 are fixed to the top surface of the activated carbon filter 11, and each... Each hollow cylinder 12 is filled with desiccant 14, and the top of each hollow cylinder 12 abuts against the inner wall of the filter assembly 4. Several small square holes 8 are opened in the middle of the end face of the sealing cover 2, and a large square hole 9 is opened at the edge of the end face of the sealing cover 2. The filter assembly 4 is connected to one side of the top surface of the sealing cover 2, which can perform deep purification of the air entering the sealing cover 2. A dustproof net 5 is embedded on the other side of the top surface of the sealing cover 2. The dustproof net 5 can initially block larger dust particles in the air from entering the interior of the sealing cover 2, acting as the first line of defense. A flange joint 10 is welded to the top of the filter assembly 4, which facilitates connection to external ventilation ducts or other equipment, providing a stable airflow channel inside the sealing cover 2. An activated carbon filter 11 is sealed at the connection between the filter assembly 4 and the sealing cover 2. The activated carbon filter 11 has a strong adsorption capacity and can effectively adsorb odors, harmful gases, and some small particulate impurities in the air, further improving the cleanliness of the air entering the sealing cover 2. Several perforated cylinders 12 are fixed to the top surface of the activated carbon filter screen 11. Each perforated cylinder 12 is filled with desiccant 14, which absorbs moisture from the air entering the filter assembly 4, preventing moisture from entering the sealed cover 2. The top of each perforated cylinder 12 abuts against the inner wall of the filter assembly 4. This design ensures the stable placement of the perforated cylinder 12 within the filter assembly 4, preventing it from shaking during operation. Several small square holes 8 are opened in the middle of the end face of the sealed cover 2 for passing through small wires. A large square hole 9 is opened at the edge of the end face of the sealed cover 2 for passing through large wires or a combination of multiple wires. The small square holes 8 and the large square hole 9 not only meet the connection requirements of wires of different specifications, but also achieve sealing at the wire passage points through the subsequent wire clips 7. The model of the switch body 1 is: Shanghai Aoxun OX-850H.

[0028] Please see Figure 1 and Figure 2Line clips 7 are inserted into the inner sides of the large square hole 9 and several small square holes 8. The line clips 7 are composed of two separate T-shaped parts, and the two T-shaped parts of the line clips 7 have tapered grooves on their facing surfaces. This separate structure facilitates the installation and removal of the line. The tapered grooves on the facing surfaces of the two T-shaped parts can accommodate lines of different diameters. When the line passes through the groove, the two T-shaped parts move closer to each other, and the groove tightly wraps the line, thus forming a seal between the line and the square hole, effectively preventing dust and moisture from entering the sealing cover 2 from the line penetration point.

[0029] Please see Figure 3 Two sets of plug-in sleeves 15 are welded to the inner wall of the sealing cover 2, and a trapezoidal plug 16 is inserted into each plug-in sleeve 15. One end of the trapezoidal plug 16 contacts the edge of the bottom surface of the activated carbon filter 11, and the other end of the trapezoidal plug 16 is provided with a magnet 17 that is attracted to the plug-in sleeve 15. The trapezoidal plug 16 supports and fixes the activated carbon filter 11, preventing the activated carbon filter 11 from shifting during the operation of the device and ensuring the stability of its filtration effect. The magnet 17 at the other end of the trapezoidal plug 16 can make the trapezoidal plug 16 and the plug-in sleeve 15 adhere tightly together, further enhancing the fixing effect of the trapezoidal plug 16 on the activated carbon filter 11, and also facilitating the quick disassembly and installation of the trapezoidal plug 16, making it convenient to replace the activated carbon filter 11.

[0030] Please see Figure 1 and Figure 2 The mounting leg 3 has an L-shaped structure, and a screw hole is provided at the end of the mounting leg 3 that connects to the outer shell of the switch body 1. The L-shaped structure of the mounting leg 3 can form a stable fit and support with the outer shell of the switch body 1. The screw hole at the end of the mounting leg 3 that connects to the outer shell of the switch body 1 allows for a quick-release screw to pass through the screw hole and fix it to the outer shell of the switch body 1. This not only achieves a firm installation between the sealing cover 2 and the switch body 1, but also makes it easy to inspect or replace the internal components of the sealing cover 2 later, greatly improving the ease of maintenance of the device.

[0031] Please see Figure 3 and Figure 4The hollow cylinder 12 has a loose column 13 fixed inside, and several conical discs are welded at equal intervals from top to bottom on the surface of the loose column 13. The diameter of the conical discs of the loose column 13 is smaller than the inner diameter of the hollow cylinder 12. This design can increase the contact area between the desiccant 14 and the air, and improve the moisture absorption efficiency of the desiccant 14. On the other hand, the conical discs can provide some support and dispersion for the desiccant 14, prevent the desiccant 14 from accumulating in the hollow cylinder 12, and ensure that the air can pass through the desiccant 14 smoothly, thereby giving full play to the moisture absorption effect of the desiccant 14.

[0032] Please see Figure 1 and Figure 2 The surface of the sealing cover 2 is provided with a dust baffle 6 corresponding to the dustproof net 5, and the bottom surface of the dust baffle 6 is provided with multiple pillars welded to the sealing cover 2. The pillars support the dust baffle 6, so that a certain gap is formed between the dust baffle 6 and the dustproof net 5. This not only does not affect the ventilation effect of the dustproof net 5, but also prevents larger external particles from falling directly onto the dustproof net 5, reducing the dust accumulation rate of the dustproof net 5 and extending its cleaning cycle.

[0033] Please see Figure 2 A rubber sealing ring is bonded to the open end of the sealing cover 2, and the rubber sealing ring abuts against the tail end of the switch body 1. The rubber sealing ring has good elasticity and sealing performance. When the sealing cover 2 is fixedly connected to the switch body 1 by the mounting feet 3, the rubber sealing ring will abut tightly against the tail end of the switch body 1, completely sealing the gap between the sealing cover 2 and the switch body 1, effectively preventing dust and moisture from entering the interior of the sealing cover 2 from the connection point between the two, and further improving the overall sealing performance of the device.

[0034] The implementation principle of this embodiment is as follows: When in use, the sealing cover 2 is attached to the tail end of the switch body 1, and the connection gap between the two is sealed by the rubber sealing ring. The L-shaped structure of the mounting feet 3 and the quick-release screws ensure that the sealing cover 2 is installed firmly, forming a relatively closed protective space, which isolates a large amount of external dust and moisture as a whole. External air enters the sealing cover 2 after being initially filtered by the dustproof net 5 to remove larger dust particles. The dust baffle 6 reduces the amount of debris falling on the dustproof net 5. Meanwhile, air entering through flange connector 10 enters filter assembly 4, first absorbing moisture through desiccant 14 in hollow cylinder 12. The conical disc of loose column 13 increases the contact area between desiccant 14 and air, improving moisture absorption efficiency. Then, it passes through activated carbon filter 11 to adsorb odors, harmful gases, and minute impurities. The purified air enters sealing cover 2, ensuring that the internal air is clean and dry. In terms of line sealing, the line passes through small square hole 8 and large square hole 9 respectively, and is inserted between the two split T-shaped parts of line clip 7. The conical line clip groove tightly wraps the line as the two parts approach, achieving a seal between the line and the square hole, preventing dust and moisture from entering from here. At the same time, the trapezoidal plug 16 and the magnet of plug sleeve 15 are connected to fix activated carbon filter 11, ensuring stable operation of each component and jointly achieving effective dust and moisture protection for the switch port.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
