Description

Plug-in frame, network equipment and communication system

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 15, 2023, with application number 202323446314.8 and application name “A plug-in frame, network equipment and communication system”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The utility model relates to the technical field of communications, and in particular to a plug-in frame, network equipment and a communication system. Background Art

[0003] Subracks are mainly used in optical access central office equipment, switches, data centers, servers and other network equipment for processing and distributing data or signals.

[0004] The subrack is provided with a connection port for connecting to an optical fiber cable. However, during operation, the connection between the subrack and the cable is easily damaged by falling foreign objects and hitting the connection.

[0005] Utility Model Content

[0006] The purpose of the present application is to provide a plug-in frame, a network device and a communication system for preventing the connection position between the cable and the plug-in frame from being damaged by foreign objects falling and hitting the cable or the plug-in frame.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] In one aspect of an embodiment of the present application, a subrack is provided, comprising a service structure and a heat sink assembly. The service structure comprises multiple boards and multiple ports. The ports are disposed on the boards and are used to connect to cables. The heat sink assembly is stacked on the service structure, protruding from a side of the service structure where the ports are located.

[0009] As can be seen from the above, the business structure includes multiple single boards and ports provided on the single boards. The single boards can be connected to external cables through the ports to send and receive signals. The heat dissipation assembly is stacked on the business structure, and the heat dissipation assembly protrudes from the side of the business structure with the port. When a foreign object falls from above the business structure, the portion of the heat dissipation assembly protruding from the business structure can block the position where the port is located. After the cable is connected to the port, the portion of the heat dissipation assembly protruding from the business structure can block the connection position between the cable and the port. This prevents the cable at the connection position or the port of the plug-in frame from being hit by falling foreign objects. This achieves the purpose of preventing foreign objects from falling and hitting the connection position between the cable and the plug-in frame, causing damage to the cable or the plug-in frame.

[0010] In some embodiments of the present application, the aforementioned service structure may have a first and second opposing surfaces. The port is located on the first surface. The distance between the end of the heat dissipation component facing away from the second surface and the first surface is h, where 0 cm < h ≤ 100 cm. For example, h can be 1 cm, 10 cm, 30 cm, 50 cm, 70 cm, 90 cm, 100 cm, etc. After the cable is connected to the port, the cable is located on the side of the first surface facing away from the second surface. In this case, the cable protrudes from the first surface. When the distance h between the end of the heat dissipation component facing away from the second surface and the first surface is greater than 0 cm, the heat dissipation component protrudes from the side of the service structure with the port. That is, the portion of the heat dissipation component protruding from the first surface can shield the cable from the port connection. Furthermore, when h is larger, the portion of the heat dissipation component protruding from the first surface can also shield the portion of the cable protruding from the first surface, thereby preventing foreign objects from falling and striking the shielded portion of the cable. Furthermore, as the cable moves away from the port, it will gradually sag under the action of gravity. At this point, the cable will not continue to extend away from the first surface. That is, the cable protrusion from the first surface will not increase indefinitely. When the distance h between the end of the heat dissipation assembly facing away from the second surface and the first surface is less than or equal to 100 cm, the portion of the cable protruding from the first surface is shielded while reducing the size of the heat dissipation assembly, thereby saving costs.

[0011] In some embodiments of the present application, a heat dissipation gap is provided between two adjacent boards, and the heat dissipation assembly may include a heat dissipation frame and at least one fan disposed within a heat dissipation cavity. The heat dissipation frame protrudes from the side of the service structure with the port, and the heat dissipation frame includes a heat dissipation cavity that communicates with the heat dissipation gap. As can be seen from the above, the heat dissipation frame of the heat dissipation assembly includes a heat dissipation cavity, and the fan may be disposed within the heat dissipation cavity. When the fan is operating, it generates airflow, thereby causing air to flow between the heat dissipation cavity and the heat dissipation gap to dissipate heat. Furthermore, the side of the heat dissipation frame facing away from the back protrudes from the service structure. If foreign objects fall during fan installation or removal, the portion of the heat dissipation frame protruding from the side of the service structure with the port shields the connection point between the cable and the port. This prevents the cable or the port of the plug-in frame at the connection point from being struck by falling foreign objects. This prevents foreign objects from falling during fan installation or removal from striking the connection point between the cable and the plug-in frame, potentially damaging the cable or the plug-in frame. Furthermore, the side of the heat dissipation frame facing away from the back protrudes from the service structure. The size of the heat dissipation frame is relatively large, and the heat dissipation cavity of the heat dissipation frame can accommodate a greater number of fans, thereby improving the heat dissipation effect of the heat dissipation component.

[0012] In some embodiments of the present application, the heat dissipation assembly further includes an air mixing frame, which is arranged between the business structure and the heat dissipation frame, and the air mixing frame has an air mixing cavity, and the heat dissipation cavity and the heat dissipation gap are respectively connected to the air mixing cavity. When the fan is working, the airflow generated converges in the air mixing cavity, and then a relatively uniform airflow is generated in the air mixing cavity, prompting a heat dissipation gap below the air mixing frame to generate airflows with similar air volumes in different areas on the same horizontal plane, so that the same heat dissipation gap can be evenly dissipated in different areas on the same horizontal plane. Alternatively, when there are multiple heat dissipation gaps, airflows with similar air volumes can be generated in different heat dissipation gaps, and then different heat dissipation gaps can be evenly dissipated. In addition, when there are multiple fans, when one of the fans fails, the airflows generated by the operation of the other fans can converge in the air mixing cavity, ensuring that the heat dissipation assembly can dissipate heat in the heat dissipation gap below the failed fan.

[0013] In some embodiments of the present application, the plug-in frame may further include a power supply board vertically arranged in the air mixing chamber, and the single board and the fan are electrically connected to the power supply board. The power supply board can be electrically connected to an external power supply. After the external power supply transmits the electric energy to the power supply board, the power supply voltage input is converted into the various levels of working voltage required by the single board or the fan through the power supply board, and distributed to the single board and the fan to ensure the energy required for the single board and the fan to work. In addition, the power supply board is a plate-shaped structure, and the thickness of the power supply board is much smaller than the width of the air mixing structure, that is, the space occupied by the power supply board in the air mixing chamber is very small. Because the power supply board is vertically arranged in the air mixing chamber, the power supply board will hardly hinder the upward and downward airflow generated in the air mixing chamber, thereby reducing the wind resistance in the air mixing chamber and ensuring the heat dissipation effect of the heat dissipation component.

[0014] In some embodiments of the present application, the business structure has a first side and a second side relative to each other, and the port is located on the first side. The plug-in frame may further include a cover plate arranged at the end of the air mixing frame facing away from the second side. The cover plate is connected to the business structure at one end facing the business structure, and is connected to the air mixing frame at one end facing away from the business structure. And the cover plate covers the end face of the air mixing frame facing away from the second face. As can be seen from the above, the cover plate covers the end face of the air mixing frame facing away from the second face, thereby shielding the air mixing frame and the power board, preventing external foreign objects from hitting and damaging the air mixing frame or the power board, thereby protecting the air mixing frame and the power board arranged in the air mixing chamber.

[0015] In some embodiments of the present application, the air mixing frame is detachably connected to the business structure. The plug-in frame may further include a support member, the support member is connected to the business structure, and the cover plate is rotatably connected to the support member at one end facing the business structure. As can be seen from the above, the air mixing frame is detachably connected to the business structure, and when the air mixing frame or the power board provided in the air mixing chamber needs to be repaired or replaced, the air mixing frame can be taken out for easy repair or replacement. In addition, the support member is connected to the business structure, and the cover plate is rotatably connected to the support member at one end facing the business structure. When disassembling the air mixing frame, the cover plate can be flipped downward to facilitate the removal of the air mixing frame. Moreover, after the cover plate is flipped downward, the cover plate can shield the port of the business structure, thereby preventing foreign objects generated during the installation or disassembly of the air mixing frame from falling and hitting the connection position between the external cable and the port. This is to achieve the purpose of preventing foreign objects from falling and hitting the connection position between the cable and the plug-in frame, thereby damaging the cable or the plug-in frame.

[0016] In some embodiments of the present application, the plug-in frame further includes a backplane assembly, the business structure and the heat dissipation assembly are both arranged on the same side of the backplane assembly, and the backplane assembly includes a backplane body and a cable group, a first connector, and a second connector arranged on the backplane body. One end of the first connector is electrically connected to the cable group, and the other end is electrically connected to the single board; one end of the second connector is electrically connected to the cable group, and the other end is electrically connected to the heat dissipation assembly. Among them, the backplane body can support the business structure and ensure the structural stability of the plug-in frame. The cable group and the single board are respectively electrically connected to the first connector, and electric energy is input to the cable group and transmitted to the single board through the first connector to provide energy for the operation of the single board. In addition, when there are multiple single boards, signals can also be transmitted and exchanged between different single boards through the cable group. In addition, the cable group and the heat dissipation assembly are respectively electrically connected to the second connector, and electric energy is input to the cable group and transmitted to the heat dissipation assembly through the second connector to provide energy for the operation of the heat dissipation assembly.

[0017] In some embodiments of the present application, the subrack may further include a power board, and the backplane assembly may further include a third connector, one end of the third connector being electrically connected to the cable assembly, and the other end being electrically connected to the power board. The power board is connected to the cable assembly via the third connector, and electrical energy is input to the power board, transmitted through the third connector to the cable assembly, and ultimately to the boards and heat dissipation assembly, thereby providing energy for the operation of the boards and heat dissipation assembly.

[0018] Another aspect of the present invention provides a network device, which may include the aforementioned subrack and a cable connected to a port of the subrack. The aforementioned network device has the same technical effects as the subrack provided in the aforementioned embodiment, and will not be described in detail here.

[0019] In another aspect of the embodiments of the present application, a communication system is provided. The communication system may include the aforementioned network device and a first access device connected to the network device. The aforementioned communication system has the same technical effects as the subrack provided in the aforementioned embodiment and is not further described here. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

Thus, a feature specified as "first," "second," "third," etc., may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0031] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be an electrical connection or an optical fiber connection; or, "connection" can be a fixed mechanical connection, a detachable mechanical connection, or an integrated one; or, "connection" can be a direct connection or an indirect connection through an intermediate medium.

[0032] In the embodiments of this application, words such as "exemplarily" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" is intended to present the relevant concepts in a concrete manner.

[0033] In the drawings of the embodiments of the present application, components are represented by guide lines with arrows; parts are represented by guide lines only; and hollow structures such as openings and holes are represented by guide lines with a hollow circle at one end.

[0034] An embodiment of the present application provides a communication system 01, as shown in Figure 1. The communication system 01 may include a network device 02 and a first access device 03 connected to the network device 02. The first access device 03 may send signals to the network device 02, and the network device 02 may process or store the received signals. Alternatively, the network device 02 may send signals to the first access device 03, thereby enabling signal exchange between the network device 02 and the first access device 03.

[0035] Continuing with Figure 1 , the communication system 01 may also include multiple second access devices 04 connected to the network device 02. Similar to the first receiving device 03 described above, the second access devices 04 and the network device 02 can also exchange signals. For example, the network device 02 may receive a signal from the first access device 03, process and distribute the signal, and then transmit the signal to different second access devices 04. Alternatively, the network device 02 may receive a signal from a second access device 04 and transmit the signal to the first access device 03.

[0036] The above embodiment is shown in Figure 1, which takes the communication system 01 as an example, including 1 network device 02, 1 first access device 03 and 2 second access devices 04. In other embodiments of the present application, the number of network devices 02, first access devices 03 and second access devices 04 can be other numbers.

[0037] Continuing with FIG1 , network device 02 includes a subrack 10 and a cable 20. One end of cable 20 is connected to subrack 10, and the other end of cable 20 is connected to first access device 03 or second access device 04. First access device 03 or second access device 04 is connected to subrack 10 via the corresponding cable 20, thereby transmitting signals.

[0038] The network device 02 mentioned above may be an optical access central office device, a switch, a data center, a server, etc. For ease of description, the following description will be made by taking the network device 02 as an optical access central office device as an example.

[0039] As shown in Figure 2, the network device 02 of the communication system 01 is an optical access central office device. In some embodiments of the present application, the first access device 03 can be a central computer room or a base station, and the second access device 04 can be an optical network terminal (ONT) or an optical network unit (ONU). The cable 20 of the optical access central office device is a fiber optic cable. The optical access central office device also includes a distribution frame 30. The subrack 10 is connected to the first access device 03 via a fiber optic cable and exchanges optical signals. Simultaneously, the subrack 10 is connected to the distribution frame 30 via a fiber optic cable and exchanges optical signals. Therefore, after the first access device 03 sends the optical signal to the subrack 10, it is distributed by the subrack 10 to different distribution frames 30, and then distributed by different distribution frames 30 to different second access devices 04. Alternatively, the second access device 04 sends the optical signal to the subrack 10 via the distribution frame 30, and the subrack 10 processes it and then sends it to the first access device 03, thereby completing the transmission of the optical signal.

[0040] The above embodiment, as shown in FIG2 , takes as an example a communication system 01 including one optical access central office device, one first access device 03, and two second access devices 04, and the optical access central office device includes one subrack 10 and two patch panels 30. In other embodiments of the present application, the number of optical access central office devices, first access devices 03, and second access devices 04 can be other numbers. The number of subracks 10 and patch panels 30 can also be other numbers.

[0041] Based on this, in some embodiments of the present application, the above-mentioned subrack 10 may include a service structure 11 and a heat dissipation component 12 as shown in Figure 3. The service structure 11 includes multiple boards 111 and multiple ports 112. The ports 112 are provided on the boards 111, and the ports 112 are used to connect to the cable 20 as shown in Figure 4. At this time, when the cable 20 is connected to the port 112 provided on the board 111, the board 111 can be connected to the cable 20 through the port 112, and can then receive the signal transmitted from the first access device 03 (as shown in Figure 2) or the second access device 04 (as shown in Figure 2) to the cable 20. Alternatively, the board 111 can also send a signal to the first access device 03 or the second access device 04 through the cable 20.

[0042] In addition, as shown in FIG4 , the heat dissipation component 12 is stacked on the business structure 11, and the heat dissipation component 12 protrudes from the side where the port 112 (as shown in FIG3 ) of the business structure 11 is located. That is, there is a gap between the end of the heat dissipation component 12 that is away from the second surface 114 as shown in FIG4 and the first surface 113. After the cable 20 is connected to the port 112, the portion of the heat dissipation component 12 that protrudes from the business structure 11 can shield the connection position between the cable 20 and the port 112. When a foreign object 05 falls from above the business structure 11, the portion of the heat dissipation component 12 that protrudes from the business structure 11 can prevent the cable 20 at the connection position or the port 112 of the plug-in frame 10 from being hit by the falling foreign object 05. This is to achieve the purpose of preventing the cable 20 or the plug-in frame 10 from being damaged due to the foreign object 05 falling and hitting the connection position between the cable 20 and the plug-in frame 10.

[0043] Furthermore, as shown in FIG4 , in some embodiments of the present application, the above-mentioned business structure 11 may have a first surface 113 and a second surface 114 relative to each other. The port 112 (as shown in FIG3 ) is located on the first surface 113. The distance between the end of the heat dissipation component 12 facing away from the second surface 114 and the first surface 113 is h; wherein 0cm<h≤100cm. When h is greater than 0cm, the heat dissipation component 12 protrudes from the side of the business structure 11 having the port 112, that is, the portion of the heat dissipation component 12 protruding from the first surface 113 can block the connection position between the cable 20 and the port 112, thereby preventing the cable 20 at the connection position or the port 112 of the frame 10 from being damaged by the impact of falling foreign objects 05.

[0044] Furthermore, after the cable 20 is connected to the port 112, it is located on the side of the first surface 113 facing away from the second surface 114. At this point, the cable 20 protrudes from the first surface 113. To protect the portion of the cable 20 protruding from the first surface 113, the distance h between the end of the heat sink 12 facing away from the second surface 114 and the first surface 113 can be set larger. This allows the portion of the heat sink 12 protruding from the first surface 113 to shield the portion of the cable 20 protruding from the first surface 113, further protecting the portion of the cable 20 near the port 112 from damage caused by falling foreign objects. Furthermore, as the cable 20 moves away from the port 112, it gradually sags under the influence of gravity. At this point, the cable 20 will not continue to extend away from the first surface 113. In other words, the extent of the cable 20 protruding from the first surface 113 will not increase indefinitely. Generally, the extent of the cable 20 protruding from the first surface 113 is less than 100 cm. At this time, when the distance h between the end of the heat dissipation component 12 facing away from the second surface 114 and the first surface 113 is less than 100 cm, the portion of the cable 20 protruding from the first surface 113 is shielded while reducing the size of the heat dissipation component 12, thereby saving costs.

[0045] For example, as shown in FIG4 , the distance h between the end of the heat dissipation assembly 12 facing away from the second surface 114 and the first surface 113 can be 1 cm, 10 cm, 30 cm, 50 cm, 70 cm, 90 cm, 100 cm, etc. During actual design and production, the value of the distance h between the end of the heat dissipation assembly 12 facing away from the second surface 114 and the first surface 113 can be appropriately selected based on the type of cable 20 connected to the subrack 10 and the size of the cable 20 protruding from the first surface 113 after the cable 20 is connected to the subrack 10.

[0046] On this basis, in some embodiments of the present application, as shown in FIG3 , a heat dissipation gap 115 is provided between two adjacent single boards 111. As shown in FIG5 , the heat dissipation assembly 12 may include a heat dissipation frame 121 and at least one fan 122. The heat dissipation frame 121 has a heat dissipation cavity 1211, which is connected to the heat dissipation gap 115. The fan 122 is disposed in the heat dissipation cavity 1211. When the fan 122 starts working, the fan 122 generates an airflow, thereby generating a gas flow between the connected heat dissipation cavity 1211 and the heat dissipation gap 115, thereby causing the hotter gas in the heat dissipation gap 115 to flow out of the heat dissipation gap 115, thereby reducing the temperature in the heat dissipation gap 115 between the single boards 111, so as to achieve heat dissipation of the single boards 111.

[0047] In addition, as shown in Figure 5, the heat dissipation frame 121 can protrude from the side of the service structure 11 having the port 112 (as shown in Figure 3). When a foreign object 05 (as shown in Figure 4) falls during the installation or removal of the fan 122, the side of the heat dissipation frame 121 close to the service structure 11 can block the connection position between the cable 20 (as shown in Figure 4) and the port 112. This prevents the cable 20 at the connection position or the port 112 of the plug-in frame 10 from being hit by the foreign object 05. This prevents the foreign object 05 from being generated and falling during the installation or removal of the fan 122, hitting the connection position between the cable 20 and the plug-in frame 10 and causing damage to the cable 20 or the plug-in frame 10. In addition, because the heat dissipation frame 121 protrudes from the service structure 11, that is, the size of the end face of the heat dissipation frame 121 facing the service structure 11 can be larger than the size of the end face of the service structure 11 facing the heat dissipation frame 121. Compared with the related art, the heat dissipation component 12 is flush with the end face of the service structure 11. The heat dissipation frame 121 in the plug-in frame 10 provided in the embodiment of the present application can be larger in size, and the heat dissipation cavity 1211 of the heat dissipation frame 121 can accommodate a larger number of fans 122 , thereby improving the heat dissipation effect of the heat dissipation component 12 .

[0048] For example, as shown in FIG5 , the side of the heat dissipation frame 121 facing the service structure 11 has a first vent (not shown in the figure) that is connected to the heat dissipation gap 115 (shown in FIG3 ). The first vent can be formed by the skeleton of the heat dissipation frame 121 facing the service structure 11. The side of the heat dissipation frame 121 facing away from the service structure 11 has a second vent (not shown in the figure), which is connected to the outside atmosphere. When the fan 122 is in operation, it can blow air toward the second vent, so that an airflow is generated in the heat dissipation cavity 1211, flowing from the first vent through the heat dissipation cavity 1211, and then flowing to the second vent. Because the heat dissipation gap 115 is connected to the first vent, an airflow can be generated in the heat dissipation gap 115 to flow toward the first vent. Ultimately, within the subrack 10, an airflow is generated that flows through the heat dissipation gap 115, the first vent, the heat dissipation cavity 1211, and the second vent, and finally exits into the atmosphere through the second vent, thereby completing the heat dissipation of the subrack 10.

[0049] On this basis, as shown in FIG5 , the heat dissipation assembly 12 may include an air mixing frame 123. The air mixing frame 123 is arranged between the business structure 11 and the heat dissipation frame 121. The air mixing frame 123 has an air mixing chamber 1231, and the heat dissipation chamber 1211 and the heat dissipation gap 115 (as shown in FIG3 ) are respectively connected to the air mixing chamber 1231. Because the heat dissipation chamber 1211 and the air mixing chamber 1231 are connected, when the fan 122 is working, gas flow is generated between the connected heat dissipation chamber 1211 and the heat dissipation gap 115. Because the heat dissipation gap 115 is also connected to the air mixing chamber 1231, after gas flow is generated in the air mixing chamber 1231, gas flow is generated between the connected heat dissipation gap 115 and the air mixing chamber 1231. In other words, gas flow is generated in the heat dissipation gap 115, the air mixing chamber 1231 and the heat dissipation chamber 1211, thereby achieving heat dissipation of the frame 10. In addition, when the gas flows, the airflow will converge in the air mixing chamber 1231, thereby generating a relatively uniform airflow in the air mixing chamber 1231. This will cause airflows with similar air volumes to be generated in different areas of a heat dissipation gap 115 on the same horizontal plane below the air mixing frame 123, thereby evenly dissipating heat to different areas of the same heat dissipation gap 115 on the same horizontal plane. Alternatively, when there are multiple heat dissipation gaps 115, after the airflows in the air mixing chamber 1231 converge, airflows with similar air volumes can be generated in different heat dissipation gaps 115, thereby evenly dissipating heat to different heat dissipation gaps 115. In addition, when there are multiple fans 122, when one of the fans 122 fails, the airflows generated by the other fans 122 can converge in the air mixing chamber 1231, thereby ensuring that the heat dissipation assembly 12 can dissipate heat to the heat dissipation gap 115 below the failed fan 122.

[0050] For example, as shown in FIG7 , the air mixing chamber 1231 is a space enclosed by the skeleton of the air mixing frame 123, and the side of the air mixing frame 123 facing the heat dissipation chamber 1211 (as shown in FIG5 ) and the side of the air mixing frame 123 facing the business structure 11 (as shown in FIG5 ) are both hollow skeleton structures. In this way, it is possible to ensure that the gas in the heat dissipation gap 115 (as shown in FIG3 ) can flow to the air mixing chamber 1231 and flow to the heat dissipation chamber 1211 through the air mixing chamber 1231. In addition, the side walls of the air mixing frame 123 can also be a hollow skeleton structure. In this way, the weight of the air mixing frame 123 can be reduced, making it easier to install and remove the air mixing frame 123.

[0051] Furthermore, as shown in Figure 5 , the subrack 10 may also include a power board 13 disposed within the air mixing chamber 1231. Both the boards 111 and the fans 122 are electrically connected to the power board 13. After the power board 13 is electrically connected to an external power source, the external power source transmits electrical energy to the power board 13. The power board 13 then converts the input power voltage into the various operating voltage levels required by the boards 111 and fans 122, and then distributes the voltage to the boards 111 and fans 122 to ensure the energy required for their operation.

[0052] On this basis, as shown in Figure 7 , the power board 13 can be positioned vertically within the air mixing chamber 1231. Because the power board 13 is a plate-shaped structure, its thickness is much smaller than the width of the air mixing structure, meaning that the space occupied by the power board 13 within the air mixing chamber 1231 is very small. Furthermore, because the power board 13 is positioned vertically within the air mixing chamber 1231, it poses little obstruction to the vertical airflow generated within the air mixing chamber 1231. This reduces wind resistance within the air mixing chamber 1231 and ensures the heat dissipation effectiveness of the heat dissipation assembly 12 (shown in Figure 5 ).

[0053] In addition, as shown in Figure 5, the insertion frame 10 may further include a cover plate 14 provided at one end of the air mixing frame 123 facing away from the second surface 114. The end of the cover plate 14 facing the business structure 11 is connected to the business structure 11, and the end of the cover plate 14 facing away from the business structure 11 is connected to the air mixing frame 123. The cover plate 14 covers the end surface of the air mixing frame 123 facing away from the second surface 114. At this time, the cover plate 14 can shield the air mixing frame 123 and the power board 13, thereby preventing external foreign objects from hitting the air mixing frame 123 or the power board 13, causing damage to the air mixing frame 123 or the power board 13. This achieves the purpose of protecting the air mixing frame 123 and the power board 13 arranged in the air mixing chamber 1231.

[0054] 5 , the air mixing frame 123 is detachably connected to the service structure 11. When the air mixing frame 123 or the power board 13 disposed in the air mixing chamber 1231 needs to be repaired or replaced, the air mixing frame 123 can be removed to facilitate the repair or replacement of the power board 13.

[0055] Furthermore, as shown in Figures 5 and 6, the subrack 10 may further include a support member 15, which is connected to the service structure 11, and the cover 14 is rotatably connected to the support member 15 at one end facing the service structure 11. In this manner, the support member 15 is connected to the service structure 11, and the cover 14 is rotatably connected to the support member 15 at one end facing the service structure 11. When removing the air mixing frame 123, as shown in Figure 6, the cover 14 can be flipped downward to facilitate removal of the air mixing frame 123. Furthermore, when flipped downward, the cover 14 can also shield the port 112 (shown in Figure 3) of the service structure 11, thereby preventing foreign objects from falling during installation or removal of the air mixing frame 123 from striking the connection between the external cable 20 (shown in Figure 4) and the port 112. This prevents foreign objects from falling during installation or removal of the air mixing frame 123 from striking the connection between the cable 20 and the subrack 10, potentially damaging the cable 20 or the subrack 10.

[0056] In some embodiments of the present application, as shown in Figure 5 , the subrack 10 may further include a backplane assembly 16, with the service structure 11 and the heat sink assembly 12 disposed on the same side of the backplane assembly 16. The backplane assembly 16 may include a backplane body 161. The service structure 11 and the heat sink assembly 12 are disposed on one side of the backplane body 161, which supports the service structure 11 and the heat sink assembly 12, ensuring the structural stability of the subrack 10.

[0057] Continuing with FIG5 , the backplane assembly 16 may further include a cable assembly 162 and a first connector 163 disposed on the backplane body 161. One end of the first connector 163 is electrically connected to the cable assembly 162, and the other end is electrically connected to the single board 111. At this point, the cable assembly 162 and the single board 111 are respectively electrically connected to the first connector 163. After inputting electrical energy into the cable assembly 162, it can be transmitted to the single board 111 through the cable assembly 162 and the first connector 163, providing energy for the operation of the single board 111. In addition, when there are multiple single boards 111, signals can also be transmitted and exchanged between different single boards 111 through the cable assembly 162.

[0058] Continuing with FIG5 , the backplane assembly 16 may further include a second connector 164 disposed on the backplane body 161. One end of the second connector 164 is electrically connected to the cable assembly 162, and the other end is electrically connected to the heat sink assembly 12. In this case, the cable assembly 162 and the heat sink assembly 12 are each electrically connected to the second connector 164. When electrical energy is input to the cable assembly 162, it is transmitted through the cable assembly 162 and the second connector 164 to the heat sink assembly 12, providing energy for the operation of the heat sink assembly 12.

[0059] Continuing with FIG5 , the backplane assembly 16 may further include a third connector 165 disposed on the backplane body 161. One end of the third connector 165 is electrically connected to the cable assembly 162, and the other end is electrically connected to the power board 13. The power board 13 is connected to the cable assembly 162 via the third connector 165. When electrical energy is input to the power board 13, it is transmitted through the third connector 165 to the cable assembly 162, and ultimately to the single board 111 and the heat sink assembly 12, providing energy for the operation of the single board 111 and the heat sink assembly 12.
