A communication device

Abstract

The application discloses a communication device, comprising a host, a dustproof plate and a movable cover plate assembly. The dustproof plate is used to cover a display through hole on the host, so that the communication interface is isolated from the environment outside the host. In the state that the communication interface is not used, dust is prevented from entering the communication interface, and the communication interface is well protected, so that problems such as dust deposition and blockage of the communication interface are prevented, and the reliability and stability of the communication device are improved. When the communication interface needs to be connected with a cable, the movable plate is slid to open the display through hole. At this time, the communication interface can be exposed from the display through hole, so that the cable can pass through the display through hole and be connected with the communication interface.

Description

Technical Field

[0001] This application relates to the field of communication facilities technology, and in particular to a communication device. Background Technology

[0002] Wired communication equipment primarily addresses serial communication, professional bus-based communication, industrial Ethernet communication, and the conversion between various communication protocols. It mainly includes devices such as routers, switches, and modems. However, the communication interfaces of current communication equipment are typically exposed, making them susceptible to blockage due to dust and other factors.

[0003] In related technologies, for example, patent CN215222376U provides a multi-channel communication device that can be embedded in a communication device. The device utilizes a communication housing with a functional board installed inside. The front surface of the communication housing has a mounting groove, inside which a multi-channel interface board is installed. A dustproof box is installed at the top of the communication housing near the front surface, and a dustproof rotating shaft is installed inside the dustproof box. A rotating wheel is installed at the end of the dustproof rotating shaft, and a dustproof cloth is installed on the outer surface of the dustproof rotating shaft. A ventilation opening is located in the middle of the bottom of the communication housing. A mounting plate is installed on the outer surface of the communication housing, and a sliding rod is inserted into the mounting plate. The bottom end of the sliding rod has a slot, and a fixing rod is installed on the inner surface of the slot via a rotating shaft. By using the dustproof box and dustproof cloth, dust accumulation at the multi-channel interfaces is prevented, ensuring good contact at the multi-channel interfaces and stable operation of the communication device. After the interfaces on the multi-channel interface board are connected, the multi-channel interface board is covered with a dustproof cloth and fixed with magnetic strips to prevent dust from falling into the interfaces.

[0004] However, this communication device uses a dustproof cloth for dust prevention, but the dustproof cloth can only prevent dust in the absence of wind. When there is airflow disturbance, the dustproof cloth will be difficult to prevent dust. On the other hand, existing multi-channel communication equipment is usually placed on a cabinet. When fixing the communication equipment, it is necessary to use tools such as screws and wrenches to fix it, which is not conducive to the convenience of operation. Summary of the Invention

The embedding component is used to be disposed on a fixed object, and the rotating part is used to drive the rotating shaft to rotate relative to the fixing block, so that one end of the rotating shaft is connected to the embedding component to fix the communication device to the fixed object.

[0014] As an optional implementation, in the embodiments of this application, the embedded component is provided with a locking groove, and the end of the rotating shaft for connecting with the embedded component is provided with a locking disc. When the rotating shaft is connected to the embedded component, the locking disc is engaged with the locking groove.

[0015] As an optional implementation, in an embodiment of this application, the embedding component includes an embedding member and a second elastic member. The embedding member is used to be embedded in the fixing object. One end of the rotating shaft is axially movable in the embedding member. The second elastic member is disposed in the embedding member.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 4This application provides a communication device 100, which includes, but is not limited to, routers, switches, modems, and other devices. The communication devices 100 are connected to each other or to other devices via communication cables to achieve communication functions. The communication device 100 includes a host 10, a dustproof plate 20, and a movable plate assembly 30. The host 10 is provided with a communication interface 11. The dustproof plate 20 covers the side of the host 10 with the communication interface 11. The dustproof plate 20 is provided with a display through hole 21, which is provided corresponding to the communication interface 11 to expose the communication interface 11. The movable plate assembly 30 includes a movable plate 31, which is movably disposed on the dustproof plate 20 to cover or open the display through hole 21. The dust cover 20 can be used to cover the display through-hole 21 on the host 10, thereby isolating the communication interface 11 from the environment outside the host 10. When the communication interface 11 is not in use, dust is prevented from entering, providing good protection and preventing problems such as dust accumulation and blockage, thus improving the reliability and stability of the communication device 100. When a cable needs to be connected to the communication interface 11, the movable plate 31 can be slid open to reveal the display through-hole 21, allowing the cable to pass through and be plugged into the communication interface 11.

[0033] It is understood that the opening size of the display through-hole 21 is the same as or slightly larger than the size of the communication interface 11, and the display through-hole 21 is at least able to allow the communication cable to be plugged into the communication interface 11. The host 10 has a function board 13 inside, and the communication interface 11 is formed on the function board 13, with the communication interface 11 exposed on the side wall of the host 10. For example, the function board 13 typically has multiple communication interfaces 11 to meet the communication needs of the multi-channel communication device 100. Correspondingly, the dustproof plate 20 can have multiple display through-holes 21. The number, size, and location of the display through-holes 21 on the dustproof plate 20 can be specifically set according to the actual number, size, shape, and position of the communication interfaces 11. Optionally, the plane where the communication interface 11 is located is recessed relative to the edge of the host 10 to form a communication slot 14. The dustproof plate 20 can be set on the communication slot 14, and the outer side of the dustproof plate 20 is flush with the edge of the host 10. In this way, the outer contour of the entire communication device 100 will be simpler, and the dustproof plate 20 will not protrude from the host 10.

[0034] For example, the movable plate 31 can be connected to the dustproof plate 20 by sliding, rotating or flipping, so as to cover or open the display through hole 21 by changing the position of the movable plate 31. The following will be explained with the sliding connection of the movable plate 31 as an example.

[0035] In some embodiments, the inner wall of the display through-hole 21 is provided with a movable groove 211, and the movable plate 31 is slidable in the movable groove 211. When the movable plate 31 slides to open the display through-hole 21, at least a portion of the movable plate 31 is accommodated in the movable groove 211. In this way, a portion of the movable plate 31 can be housed in the movable groove 211, thereby hiding a portion of the movable plate 31 when the display through-hole 21 is opened, preventing the movable plate 31 from protruding from the dustproof plate 20. This makes the structure of the dustproof plate 20 and the movable plate 31 simpler and more compact, which is beneficial for the miniaturization design of the communication device 100. For example, when the movable plate 31 slides to open the display through-hole 21, the movable plate 31 can be completely hidden in the movable groove 211, thus obtaining a display through-hole 21 with a larger opening, which facilitates the insertion of the communication cable and the communication interface 11. Of course, the movable plate 31 can also be partially hidden in the movable groove 211, with the remaining portion exposed outside the groove 211. When it is necessary to cover the display through-hole 21, the portion of the movable plate 31 outside the groove 211 can be grasped, thereby sliding the movable plate 31 to cover the display through-hole 21. Optionally, the movable groove 211 can be arranged in a horizontal, vertical, or other direction, allowing the movable plate 31 to slide in the horizontal, vertical, or other directions. The following explanation will use the example of the movable plate 31 sliding in the vertical direction.

[0036] In some embodiments, the movable groove 211 is provided with an elastic element limiting groove 2111, and the movable plate assembly 30 further includes a first elastic element 32. The first elastic element 32 is disposed in the elastic element limiting groove 2111. One end of the first elastic element 32 abuts against the inner wall of the elastic element limiting groove 2111, and the other end abuts against the movable plate 31. The first elastic element 32 is used to provide elastic force to the movable plate 31 when the movable plate 31 covers the display through hole 21. When the movable cover opens the display through-hole 21, the movable cover and the elastic element limiting groove 2111 together press the first elastic element 32, causing the first elastic element 32 to deform under pressure. When the movable cover closes the display through-hole 21, on the one hand, the first elastic element 32 can provide elastic force for the movement of the movable plate 31, making it easy for the movable plate 31 to automatically close the display through-hole 21, thereby sealing the communication interface 11 and preventing dust from entering the communication interface 11. The automatic closing of the display through-hole 21 by the movable plate 31 can improve the ease of operation of the movable plate 31 and improve the practicality of the communication device 100. On the other hand, when the movable cover closes the display through-hole 21, the first elastic element 32 can provide holding force to keep the movable plate 31 in the sealed position, preventing the movable plate 31 from being opened, thereby keeping the display through-hole 21 in a closed state.

[0037] To make the movable plate 31 more stable during sliding, in some embodiments, the inner walls of opposite sides of the movable groove 211 are provided with elastic element limiting grooves 2111. The first elastic element 32 includes two springs, which are respectively disposed in the elastic element limiting grooves 2111. In this way, the two springs can provide elastic force on both sides of the movable plate 31 simultaneously, avoiding problems such as displacement or lateral tilting of the movable plate 31 during sliding, thereby improving the stability and reliability of the sliding process of the movable plate 31.

[0038] In some embodiments, the bottom wall of the movable slot 211 is provided with a snap-fit ​​groove 2112, and the bottom of the movable plate 31 is provided with a snap-fit ​​block 311. When the movable plate 31 covers the display through hole 21, the snap-fit ​​block 311 engages with the snap-fit ​​groove 2112. By utilizing the cooperation between the snap-fit ​​block 311 and the snap-fit ​​groove 2112, the movable plate 31 can be positioned when it covers the display through hole 21, so that the movable plate 31 and the dustproof plate 20 are approximately parallel, preventing the movable plate 31 from shifting and improving the accuracy of the movable plate 31 during installation and use. Optionally, the snap-fit ​​block 311 can extend along the length direction of the movable plate 31, and correspondingly, the snap-fit ​​groove 2112 also extends in the same direction, thereby realizing the mutual snap-fit ​​between the two.

[0039] In some embodiments, a lifting plate 312 protrudes from the outer side of the movable plate 31, and when a portion of the movable plate 31 is accommodated in the movable groove 211, the lifting plate 312 is located outside the movable groove 211. The lifting plate 312 provides a structure that facilitates removal during the sliding of the movable plate 31, thereby causing the movable plate 31 to slide open or close the display through hole 21. Exemplarily, the lifting plate 312 may be a protrusion protruding from the outer surface of the movable plate 31, or a strip-shaped protrusion extending along the length of the movable plate 31, etc. When a portion of the movable plate 31 is accommodated in the movable groove 211, the lifting plate 312 is located outside the movable groove 211, thus facilitating the gripping of the lifting plate 312 when the movable plate 31 needs to be slid next time.

[0040] In some embodiments, an interface label 313 is provided on the outer side of the movable plate 31. The interface label 313 is used to indicate the shape of the communication interface 11. Using the interface label 313, the user can quickly identify the shape or type of the communication interface 11 at each location without having to open the movable plate 31 one by one, thereby facilitating quick connection of the communication device 100 and improving ease of use. Exemplarily, the interface label 313 can be a printed material with a label pattern or text pasted on the outer side of the movable plate 31, or the label pattern can be formed directly on the outer surface of the movable plate 31 by spraying or other methods.

[0041] Communication equipment 100 typically generates a large amount of heat during operation. If this heat cannot be dissipated in a timely manner, it will affect the performance of the communication equipment 100, causing a decrease in efficiency or even damage. Therefore, in some embodiments, please refer to [the relevant documentation]. Figure 2 The communication device 100 also includes a heat dissipation module 50, which comprises a housing 51, a cooling fan 52, and a heat dissipation power interface 53. The housing 51 is located on the top of the host 10, and the space enclosed by the housing 51 communicates with the space inside the host 10. For example, the top of the host 10 may be grid-like or strip-shaped, or the top of the host 10 may have ventilation holes. The cooling fan 52 is located in the housing 51 and rotates and generates airflow after power is applied. The airflow can enter the host 10 and convect with the air inside the host 10, thereby reducing the internal temperature of the host 10 and ensuring normal operation. Furthermore, the heat dissipation power interface 53 is located in the housing 51 and electrically connected to the cooling fan 52 to supply power to the cooling fan 52 when power is applied. The heat dissipation power interface can be located on the top or side of the housing 51. Preferably, the heat dissipation power interface 53 is located on the side of the housing 51, on the side of the host 10 where the communication interface 11 is located. In this way, the communication cable connected to the host 10 and the power supply cable of the heat dissipation module 50 can be located on the same side of the entire communication device 100, which facilitates the orderly arrangement of various pipelines around the periphery of the communication device 100, reduces the difficulty of wiring the communication device 100, and thus improves the convenience of using the communication device 100. Furthermore, the side of the housing 51 where the heat dissipation power interface 53 is located is flush with the side of the host 10 where the communication interface 11 is located, which further simplifies the overall outline of the communication device 100. Optionally, a heat dissipation vent 12 can be provided on the periphery of the host 10, such as on other sides of the host 10 where the communication interface 11 is located. The heat dissipation vent 12 can be used to create air convection inside the host 10, accelerating the heat dissipation of the host 10. A downward-opening baffle can also be provided around the periphery of the heat dissipation vent 12, which can not only meet the ventilation and heat dissipation requirements of the heat dissipation vent 12, but also block dust and prevent dust from directly entering the interior of the host 10 from the heat dissipation vent 12.

[0042] Please see Figures 5 to 7To facilitate the installation and fixation of the communication device 100 in the required location, such as a rack or equipment room, in some embodiments, the communication device 100 further includes a fixing module 40. The fixing module 40 includes a fixing block 41, a rotating shaft 42, and an embedding component 43. The fixing block 41 is disposed on the outer periphery of the host 10, and its inner wall has a movable through hole 411. The rotating shaft 42 passes through the movable through hole 411, and one end of the rotating shaft 42 has a rotating part 421 located above the fixing block 41. The embedding component 43 is used to be mounted on a fixing object 200. The rotating part 421 drives the rotating shaft 42 to rotate relative to the fixing block 41, so that one end of the rotating shaft 42 is connected to the embedding component 43, thereby fixing the communication device 100 to the fixing object 200. The fixing object 200 can be a rack, equipment room, or other structure for placing the communication device 100, and the embedding component 43 can be pre-installed in the fixing object 200. Using the rotating part 421, the user can rotate the rotating shaft 42 without using other tools (such as wrenches, screwdrivers, etc.), thereby quickly fixing the communication device 100 to the fixed object 200. This simplifies the installation, maintenance, and disassembly process of the communication device 100, improving the ease and practicality of operation during the assembly and disassembly of the communication device 100. For example, the rotating part 421 can be a wing-shaped protrusion located at the end of the rotating shaft 42, or a cylindrical block with a diameter larger than the rotating shaft 42, thus requiring less effort from the user when turning the rotating shaft 42. The interaction between the rotating shaft 42 and the insert 432 achieves the effect of fixing the communication device 100 to the fixed object 200, thereby simplifying the installation and disassembly of the communication device 100 and improving the efficiency of assembly and disassembly of the communication device 100.

[0043] Optionally, since a considerable amount of force is required to screw the rotating shaft 42 into or out of the embedded assembly 43, in some embodiments, to facilitate user operation and reduce the effort required to turn the rotating shaft 42, a third elastic element 412, such as a spring, a spring sheet, or a torsion spring, is also provided in the fixing block 41. Taking a spring as an example, the spring is sleeved on the outer circumference of the rotating shaft 42, with one end abutting against the rotating shaft 42 and the other end abutting against the movable through hole 411. When the rotating shaft 42 rotates relative to the fixing block 41 and moves towards the embedded assembly 43, the rotating shaft 42 and the fixing block 41 compress the spring, causing the spring to deform under pressure. When the rotating shaft 42 is screwed out of the embedded assembly 43, the spring provides elastic force to the rotating shaft 42, thereby facilitating the better screwing of the rotating shaft 42 out of the embedded assembly 43, making it easier to turn the rotating shaft 42 and improving the convenience of disassembling the communication device 100. For example, a rotating block can be fitted around the outer periphery of the spring. The rotating block can rotate relative to the fixed block 41 in the movable through hole 411. The rotating block is fixed relative to the rotating shaft 42. When the rotating shaft 42 rotates, the rotating block follows the rotating shaft 42 and rotates simultaneously relative to the fixed block 41. One end of the spring can abut against the end of the inner wall of the rotating block.

[0044] For example, the fixing block 41 can be provided in two, four or more, to... Figure 1 For example, four fixing blocks 41 are set, and the four fixing blocks 41 are symmetrically arranged on the outer periphery of the host 10. In this way, when installing the communication device 100, the connection between the communication device 100 and the fixing object 200 can be more stable, the force on the communication device 100 during use can be more balanced, and the reliability of the installation of the communication device 100 can be improved.

[0045] To enable the rotating shaft 42 and the embedded component 43 to connect to each other, in some embodiments, the embedded component 43 is provided with a locking groove 431, and the end of the rotating shaft 42 used for connecting to the embedded component 43 is provided with a locking disc 422. When the rotating shaft 42 and the embedded component 43 are connected, the locking disc 422 is engaged with the locking groove 431. Utilizing the interlocking action of the locking disc 422 and the locking groove 431, the rotating shaft 42 and the embedded component 43 can be connected together, thereby achieving the effect of fixing the communication device 100 to the fixed object 200. The locking groove 431 and the locking disc 422 are detachably connected by a snap-fit ​​mechanism, which improves the efficiency of connection or separation and enhances the convenience of installation or disassembly.

[0046] For example, the locking disc 422 may be provided with a structure such as an elastic arm or a pin 4222. The elastic arm or pin 4222 pops out when the rotating shaft 42 is turned into place, thereby engaging in the locking groove 431, realizing the engagement connection between the rotating shaft 42 and the embedded component 43, and preventing the rotating shaft 42 from coming out of the embedded component 43. Taking the pin 4222 as an example, the locking disc 422 includes a disc body 4221 and a pin 4222. The disc body 4221 is configured as a hollow disc-shaped structure or an annular structure. The pin 4222 is disposed in the disc body 4221. The disc body 4221 is provided with an opening to allow the pin 4222 to pop out and protrude from the outer peripheral surface of the disc body 4221. The locking groove 431 is located at the bottom of the embedded component 43. When one end of the rotating shaft 42 moves to the bottom of the embedded component 43, it drives the ball 4222 to move to the position corresponding to the locking groove 431. The ball 4222 automatically pops out and locks into the locking groove 431, thereby achieving a locking connection between the rotating shaft 42 and the embedded component 43. When it is necessary to separate the rotating shaft 42 from the embedded component 43, the rotating shaft is rotated to disengage the ball 4222 from the locking groove 431, thereby unlocking the locking disc 422 from the locking groove 431. For example, the locking disc 422 can be provided with multiple balls 4222. The balls 4222 are connected to the disc body 4221 by elastic elements such as springs, so that the balls 4222 can automatically pop out from the opening of the disc body 4221. The multiple balls 4222 can be evenly spaced along the circumference of the disc body 4221.

[0047] To prevent eccentricity and other problems during the rotation of the rotating shaft 42, in some embodiments, the embedding assembly 43 includes an embedding member 432 and a second elastic member 433. The embedding member 432 is used to embed into the fixed object 200. One end of the rotating shaft 42 is axially movable in the embedding member 432. The second elastic member 433 is disposed in the embedding member 432, with one end abutting against the end of the rotating shaft 42 and the other end abutting against the bottom of the embedding member 432. Using the second elastic member 433, the rotating shaft 42 can always maintain connection with the bottom of the embedding member 432 during screwing in or out, thereby ensuring that the rotating shaft 42 remains concentric with the embedding member 432 during rotation. This facilitates smoother screwing in or out of the rotating shaft 42, avoids eccentricity, jamming, and other problems, and improves the convenience and practicality of installing or disassembling the rotating shaft 42. Optionally, the second elastic member 433 can be a spring, a sheet spring, or other similar structure.
