Description

Technical Field

[0001] The utility model relates to the technical field of communication, and in particular to a plug-in frame, network equipment and a communication system. Background Art

[0002] Plug-in frames are mainly used in optical access central office equipment, switches, data centers, servers and other network equipment for processing and distributing data or signals.

[0003] The plug-in frame is provided with a connection port for connecting with the optical fiber cable. However, during operation, the connection position between the plug-in frame and the cable is easily damaged due to the impact of falling foreign objects. Utility Model Content

[0004] The purpose of the present application is to provide a plug-in frame, a network device and a communication system, which are used to prevent the connection position between the cable and the plug-in frame from being damaged due to the impact of foreign objects falling on the cable or the plug-in frame.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In one aspect of an embodiment of the present application, a plug-in frame is provided, the plug-in frame comprising a service structure and a heat dissipation component. The service structure comprises a plurality of boards and a plurality of ports. The ports are arranged on the boards, and the ports are used to connect to cables. The heat dissipation component is stacked on the service structure, and the heat dissipation component protrudes from a side where the ports of the service structure are located.

[0007] As can be seen from the above, the business structure includes multiple single boards and ports arranged on the single boards. The single boards can be connected to external cables through the ports to send and receive signals. The heat dissipation components are stacked on the business structure, and the heat dissipation components protrude from the side of the business structure with the port. When a foreign object falls on the top of the business structure, the part of the heat dissipation component protruding from the business structure can block the position where the port is located. After the cable is connected to the port, the part of the heat dissipation component protruding from the business structure can block the connection position between the cable and the port. This prevents the cable or the port of the plug-in frame at the connection position 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 and causing damage to the cable or the plug-in frame.

[0008] In some embodiments of the present application, the above-mentioned business structure may have a first surface and a second surface relative to each other. The port is located on the first surface. The distance between the end of the heat dissipation component away from the second surface and the first surface is h; wherein 0cm<h≤100cm. Exemplarily, h can be 1cm, 10cm, 30cm, 50cm, 70cm, 90cm, 100cm, etc. After the cable is connected to the port, the cable is located on the side of the first surface away from the second surface. At this time, the cable will protrude from the first surface. When the distance h between the end of the heat dissipation component away from the second surface and the first surface is greater than 0cm, the heat dissipation component protrudes from the side of the business structure with the port, that is, the part of the heat dissipation component protruding from the first surface can block the connection position between the cable and the port. Moreover, when h is large, the part of the heat dissipation component protruding from the first surface can also block the part of the cable protruding from the first surface, thereby preventing foreign objects from falling and hitting the blocked part of the cable. In addition, as it gradually moves away from the port, the cable will gradually sag under the action of gravity. At this time, the cable will not continue to extend in the direction away from the first surface. That is, the size of the cable protruding from the first surface will not increase infinitely. 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 can be shielded while reducing the size of the heat dissipation assembly, thereby saving costs.

[0009] In some embodiments of the present application, there is a heat dissipation gap between two adjacent single boards, and the heat dissipation assembly may include a heat dissipation frame and at least one fan arranged in the heat dissipation cavity. The heat dissipation frame protrudes from the side of the business structure having a port, and the heat dissipation frame has a heat dissipation cavity, and the heat dissipation cavity is connected to the heat dissipation gap. As can be seen from the above, the heat dissipation frame of the heat dissipation assembly has a heat dissipation cavity, and the fan can be arranged in the heat dissipation cavity. When the fan is working, an airflow is generated, thereby causing the gas between the heat dissipation cavity and the heat dissipation gap to flow to achieve heat dissipation. In addition, the side of the heat dissipation frame away from the back side protrudes from the business structure. When foreign objects fall during the installation or removal of the fan, the part of the heat dissipation frame protruding from the side of the business structure having a port will block the connection position of the cable and the port. Then prevent the cable or the port of the plug-in frame at the connection position from being hit by the falling foreign objects. In order to achieve the purpose of preventing foreign objects from falling during the installation or removal of the fan, hitting the connection position of the cable and the plug-in frame and causing damage to the cable or the plug-in frame. In addition, the side of the heat dissipation frame away from the back side protrudes from the business structure. The size of the heat dissipation frame is relatively large, and the heat dissipation cavity of the heat dissipation frame can accommodate a large number of fans, thereby improving the heat dissipation effect of the heat dissipation component.

[0010] In some embodiments of the present application, the heat dissipation assembly also 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 generated airflow 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 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.

[0011] In some embodiments of the present application, the plug-in frame may also include a power board vertically arranged in the air mixing chamber, and the single board and the fan are electrically connected to the power board. The power board may be electrically connected to an external power supply. After the external power supply transmits the electric energy to the power board, the input power supply voltage is converted into various levels of working voltage required by the single board or the fan through the power 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 board is a plate-like structure, and the thickness of the power board is much smaller than the width of the air mixing structure, that is to say, the space occupied by the power board in the air mixing chamber is very small. Because the power board is vertically arranged in the air mixing chamber, the power 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.

[0012] In some embodiments of the present application, the business structure has a first surface and a second surface relative to each other, and the port is located on the first surface. The plug-in frame may also include a cover plate arranged at the end of the air mixing frame away from the second surface. 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 surface of the air mixing frame away from the second surface. From the above, it can be seen that the cover plate covers the end surface of the air mixing frame away from the second surface, thereby shielding the air mixing frame and the power board to prevent 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.

[0013] In some embodiments of the present application, the air mixing frame is detachably connected to the business structure. The plug-in frame may also include a support member, which 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 arranged 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 down to facilitate the removal of the air mixing frame. Moreover, after the cover plate is flipped down, the cover plate can cover 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. In order to achieve the purpose of preventing foreign objects from falling and hitting the connection position between the cable and the plug-in frame and causing damage to the cable or the plug-in frame.

[0014] In some embodiments of the present application, the plug-in frame also includes a backplane assembly, the service 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 service structure to ensure the structural stability of the plug-in frame. The cable group and the single board are electrically connected to the first connector respectively, and electrical 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 electrically connected to the second connector respectively, and electrical 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.

[0015] In some embodiments of the present application, the plug-in frame 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 group, and the other end being electrically connected to the power board. The power board is connected to the cable group through the third connector, and electrical energy is input to the power board, transmitted to the cable group through the third connector, and finally transmitted to the single board and the heat dissipation assembly, thereby providing energy for the operation of the single board and the heat dissipation assembly.

[0016] Another aspect of the present application provides a network device, which may include the above-mentioned plug-in frame, and the network device may also include a cable connected to a port of the plug-in frame. The above-mentioned network device has the same technical effect as the plug-in frame provided in the above-mentioned embodiment, which will not be described in detail here.

[0031] 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.

[0032] The present application embodiment provides a communication system 01, such as Figure 1 As shown, 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 a signal to the network device 02, and the network device 02 processes or stores the received signal. Alternatively, the network device 02 may send a signal to the first access device 03 to implement signal exchange between the network device 02 and the first access device 03.

[0033] Continue as Figure 1 As shown, the communication system 01 may also include a plurality of second access devices 04 connected to the network device 02. Similar to the first receiving device 03 described above, the second access device 04 and the network device 02 may also exchange signals. Exemplarily, the network device 02 may receive a signal sent by the first access device 03, and after processing and distribution, send the signal to different second access devices 04. Alternatively, the network device 02 may receive a signal sent by the second access device 04 and send it to the first access device 03.

[0034] The above embodiment Figure 1As shown, a communication system 01 includes 1 network device 02, 1 first access device 03 and 2 second access devices 04 as an example. 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.

[0035] In addition, continue as Figure 1 As shown, the network device 02 includes a plug-in frame 10 and a cable 20, one end of the cable 20 is connected to the plug-in frame 10, and the other end of the cable 20 is used to connect to the first access device 03 or the second access device 04. The first access device 03 or the second access device 04 is connected to the plug-in frame 10 through the correspondingly connected cable 20, thereby transmitting signals.

[0036] The above-mentioned network device 02 may be an optical access central office device, a switch, a data center, a server, etc. For the sake of convenience, the following description is made by taking the network device 02 as an optical access central office device as an example.

[0037] like Figure 2 As shown, the network device 02 of the communication system 01 is an optical access central office device. At this time, 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 (Optical Network Terminal, ONT) or an optical network unit (Optical Network Unit, ONU). The cable 20 of the optical access central office device is an optical fiber cable. The optical access central office device also includes a distribution frame 30. The plug-in frame 10 is connected to the first access device 03 through an optical fiber cable and exchanges optical signals. At the same time, the plug-in frame 10 is connected to the distribution frame 30 through an optical fiber cable and exchanges optical signals. Therefore, after the first access device 03 sends the optical signal to the plug-in frame 10, it is distributed to different distribution frames 30 through the plug-in frame 10, and then distributed to different second access devices 04 through different distribution frames 30. Alternatively, the second access device 04 sends the optical signal to the plug-in frame 10 through the distribution frame 30, and the plug-in frame 10 processes and sends it to the first access device 03. To complete the transmission of the optical signal.

[0038] The above embodiment Figure 2 As shown, a communication system 01 includes 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 plug-in frame 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 plug-in frames 10 and patch panels 30 can also be other numbers.

[0039] Based on this, in some embodiments of the present application, the above-mentioned plug-in frame 10 is as follows Figure 3As shown, the service structure 11 and the heat dissipation component 12 may be included. The service structure 11 includes a plurality of single boards 111 and a plurality of ports 112. The ports 112 are arranged on the single boards 111. The ports 112 are used to communicate with the Figure 4 At this time, when the cable 20 is connected to the port 112 set on the single board 111, the single board 111 can be connected to the cable 20 through the port 112, and then can receive the first access device 03 (such as Figure 2 as shown) or the second access device 04 (as shown Figure 2 Alternatively, the board 111 may also send a signal to the first access device 03 or the second access device 04 through the cable 20.

[0040] In addition, if Figure 4 As shown, the heat dissipation component 12 is stacked on the service structure 11, and the heat dissipation component 12 protrudes from the port 112 of the service structure 11 (such as Figure 3 That is, the heat dissipation component 12 is away from the side where Figure 4 There is a gap between one end of the second surface 114 and the first surface 113. After the cable 20 is connected to the port 112, the portion of the heat dissipation component 12 protruding from the service structure 11 can shield the connection position between the cable 20 and the port 112. When a foreign object 05 falls from above the service structure 11, the portion of the heat dissipation component 12 protruding from the service 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 achieves 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.

[0041] Further, continue as Figure 4 As shown, in some embodiments of the present application, the above-mentioned service structure 11 may have a first surface 113 and a second surface 114 opposite to each other. Figure 3 The heat dissipation component 12 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 service structure 11 having the port 112, that is, the portion of the heat dissipation component 12 protruding from the first surface 113 can shield 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 plug-in frame 10 from being damaged by being hit by a falling foreign object 05.

[0042] In addition, after the cable 20 is connected to the port 112, the cable 20 is located on the side of the first surface 113 away from the second surface 114. At this time, the cable 20 will protrude from the first surface 113. In order to protect the portion of the cable 20 protruding from the first surface 113, the distance h between the end of the heat dissipation component 12 away from the second surface 114 and the first surface 113 can be set larger, so that the portion of the heat dissipation component 12 protruding from the first surface 113 can also block the portion of the cable 20 protruding from the first surface 113, further protecting the portion of the cable 20 close to the port 112, and preventing the portion of the cable 20 from being damaged by the impact of falling foreign objects 05. In addition, as the cable 20 gradually moves away from the port 112, it will gradually sag under the action of gravity. At this time, the cable 20 will not continue to extend in the direction away from the first surface 113. In other words, the size of the cable 20 protruding from the first surface 113 will not increase infinitely. Generally, the size 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 size of the heat dissipation component 12 can be reduced while shielding the portion of the cable 20 protruding from the first surface 113, thereby saving costs.

[0043] For example, continue as Figure 4 As shown, the distance h between the end of the heat dissipation component 12 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. In actual design and production, the value of the distance h between the end of the heat dissipation component 12 away from the second surface 114 and the first surface 113 can be selected appropriately according to the type of the cable 20 connected to the plug-in frame 10 and the size of the cable 20 protruding from the first surface 113 after the cable 20 is connected to the plug-in frame 10.

[0044] On this basis, in some embodiments of the present application, Figure 3 As shown, there is a heat dissipation gap 115 between two adjacent single boards 111. Figure 5 As shown, 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, and the heat dissipation cavity 1211 is connected to the heat dissipation gap 115. The fan 122 is arranged in the heat dissipation cavity 1211. When the fan 122 starts to work, the fan 122 generates airflow, thereby generating 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.

[0045] In addition, continue as Figure 5 As shown, the heat dissipation frame 121 can protrude from the service structure 11 and have a port 112 (such as Figure 3 When a foreign object 05 (such as Figure 4 As shown), the side of the heat dissipation frame 121 close to the service structure 11 can be used to connect the cable 20 (as shown in FIG. Figure 4 The connection position between the cable 20 and the plug-in frame 10 is blocked. The cable 20 at the connection position or the port 112 of the plug-in frame 10 is prevented from being hit by foreign objects 05. The foreign objects 05 are prevented from being generated and falling during the installation or removal of the fan 122, and hitting the connection position between the cable 20 and the plug-in frame 10, thereby damaging the cable 20 or the plug-in frame 10. In addition, because the heat dissipation frame 121 protrudes from the business structure 11. In other words, the size of the end face of the heat dissipation frame 121 facing the business structure 11 can be larger than the size of the end face of the business structure 11 facing the heat dissipation frame 121. Compared with the related art, the structure in which the end face of the heat dissipation component 12 is flush with the end face of the business structure 11. The size of the heat dissipation frame 121 in the plug-in frame 10 provided in the embodiment of the present application can be larger, and the number of fans 122 that can be accommodated by the heat dissipation cavity 1211 of the heat dissipation frame 121 is larger, thereby improving the heat dissipation effect of the heat dissipation component 12.

[0046] For example, continue as Figure 5 As shown, the heat dissipation frame 121 has a heat dissipation gap 115 (such as Figure 3 The first vent can be surrounded by the skeleton of the heat dissipation frame 121 facing the business structure 11. The heat dissipation frame 121 has a second vent (not shown in the figure) on the side facing away from the business structure 11, and the second vent is connected to the outside atmosphere. When the fan 122 is working, it can send air toward the second vent, so that an airflow is generated in the heat dissipation cavity 1211, which flows from the first vent through the heat dissipation cavity 1211 and then flows to the second vent. Because the heat dissipation gap 115 is connected to the first vent, an airflow flowing to the first vent can be generated in the heat dissipation gap 115. Finally, in the plug-in frame 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 leaves the air through the second vent, thereby completing the heat dissipation work of the plug-in frame 10.

[0047] On this basis, continue Figure 5 As shown, the heat dissipation assembly 12 may include an air mixing frame 123. The air mixing frame 123 is disposed between the service structure 11 and the heat dissipation frame 121. The air mixing frame 123 has an air mixing chamber 1231, a heat dissipation chamber 1211 and a heat dissipation gap 115 (such as Figure 3As shown in the figure, the heat dissipation chamber 1211 and the air mixing chamber 1231 are respectively connected. 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 the 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 insertion frame 10. In addition, when the gas flows, the air flow will converge in the air mixing chamber 1231, thereby generating a relatively uniform air flow in the air mixing chamber 1231. As a result, air flow with similar air volume is generated in different areas on the same horizontal plane of a heat dissipation gap 115 below the air mixing frame 123, thereby evenly dissipating the heat of different areas on the same horizontal plane of the same heat dissipation gap 115. 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 in 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, ensuring that the heat dissipation assembly 12 can dissipate heat in the heat dissipation gap 115 located below the failed fan 122.

[0048] For example, Figure 7 As shown, the air mixing chamber 1231 is a space surrounded by the frame of the air mixing frame 123, and the air mixing frame 123 faces the heat dissipation chamber 1211 (as shown in FIG. Figure 5 As shown) and the air mixing frame 123 faces the service structure 11 (as shown) Figure 5 As shown in FIG. 1 , the heat dissipation gap 115 (as shown in FIG. 1 ) is a hollow skeleton structure. Figure 3 The gas (as shown in FIG. 1 ) can flow to the air mixing chamber 1231, and then flow to the heat dissipation chamber 1211 through the air mixing chamber 1231. In addition, the side wall 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, and the installation and removal of the air mixing frame 123 can be facilitated.

[0049] Further, continue as Figure 5 As shown, the plug-in frame 10 may further include a power board 13 disposed in the air mixing chamber 1231. The single board 111 and the fan 122 are both electrically connected to the power board 13. After the power board 13 is electrically connected to the external power supply, the external power supply transmits electric energy to the power board 13. At this time, the power board 13 converts the input power supply voltage into various levels of working voltage required by the single board 111 or the fan 122, and then distributes it to the single board 111 and the fan 122 to ensure the energy required for the single board 111 and the fan 122 to work.

[0050] On this basis, if Figure 7 As shown, the power board 13 can be vertically arranged in the air mixing chamber 1231. Because the power board 13 is a plate-shaped structure, the thickness of the power board 13 is much smaller than the width of the air mixing structure, that is, the space occupied by the power board 13 in the air mixing chamber 1231 is very small. And because the power board 13 is vertically arranged in the air mixing chamber 1231, the power board 13 will hardly hinder the airflow in the up and down directions generated in the air mixing chamber 1231, thereby reducing the wind resistance in the air mixing chamber 1231 and ensuring that the heat dissipation component 12 (such as Figure 5 The heat dissipation effect is shown).

[0051] In addition, if Figure 5 As shown, the plug-in frame 10 may also include a cover plate 14 disposed at one end of the air mixing frame 123 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 away from the business structure 11 is connected to the air mixing frame 123. And the cover plate 14 covers the end surface of the air mixing frame 123 away from the second surface 114. At this time, the cover plate 14 covers 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. To achieve the purpose of protecting the air mixing frame 123 and the power board 13 arranged in the air mixing chamber 1231.

[0052] Further, continue as Figure 5 As shown, 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 taken out to facilitate the repair or replacement of the power board 13.

[0053] Furthermore, if Figure 5 and Figure 6 As shown, the insert frame 10 may further include a support member 15, the support member 15 is connected to the service structure 11, and the end of the cover plate 14 facing the service structure 11 is rotatably connected to the support member 15. In this way, the support member 15 is connected to the service structure 11, and the end of the cover plate 14 facing the service structure 11 is rotatably connected to the support member 15. When disassembling the air mixing frame 123, as shown in FIG. Figure 6 As shown, the cover plate 14 can be turned down to facilitate the removal of the air mixing frame 123. In addition, after the cover plate 14 is turned down, the cover plate 14 can also be used to connect the port 112 (such as Figure 3 ) position to block, thereby preventing foreign objects generated during the installation or removal of the air mixing frame 123 from falling and hitting the external cable 20 (as shown Figure 4The purpose of preventing foreign objects generated during the installation or removal of the air mixing frame 123 from falling and hitting the connection position between the cable 20 and the plug-in frame 10 to cause damage to the cable 20 or the plug-in frame 10 is achieved.

[0054] In addition, in some embodiments of the present application, Figure 5 As shown, the frame 10 may further include a backplane assembly 16, and the service structure 11 and the heat dissipation assembly 12 are both arranged 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 dissipation assembly 12 are arranged on one side of the backplane body 161, and the backplane body 161 can support the service structure 11 and the heat dissipation assembly 12 to ensure the structural stability of the frame 10.

[0055] Continue as Figure 5 As shown, the backplane assembly 16 may further include a cable group 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 group 162, and the other end is electrically connected to the single board 111. At this time, the cable group 162 and the single board 111 are electrically connected to the first connector 163 respectively, and after inputting electric energy into the cable group 162, it can be transmitted to the single board 111 through the cable group 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 group 162.

[0056] Continue as Figure 5 As shown, 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 group 162, and the other end is electrically connected to the heat dissipation assembly 12. At this time, the cable group 162 and the heat dissipation assembly 12 are electrically connected to the second connector 164 respectively, and after inputting electrical energy to the cable group 162, it can be transmitted to the heat dissipation assembly 12 through the cable group 162 and the second connector 164, providing energy for the operation of the heat dissipation assembly 12.

[0057] Continue as Figure 5 As shown, 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 group 162, and the other end is electrically connected to the power board 13. The power board 13 is connected to the cable group 162 through the third connector 165, and electric energy is input to the power board 13, transmitted to the cable group 162 through the third connector 165, and finally transmitted to the single board 111 and the heat dissipation assembly 12, so as to provide energy for the operation of the single board 111 and the heat dissipation assembly 12.
