Description

Technical Field

[0001] This application relates to the field of network devices, and more particularly to a chassis-type device. Background Technology

[0002] Chassis-based devices, such as routers and switches, structurally consist of service boards and switching boards. Service boards are primarily responsible for receiving and transmitting service signals, while switching boards are primarily responsible for forwarding service signals between different service boards. For example, after a service board receives a service signal, it sends the signal to the switching board, which then forwards the signal to another service board.

[0003] In the current consumer market, miniaturization of frame-type equipment has become one of the main demands of users. Therefore, reducing the size of frame-type equipment has become a problem that needs to be solved. Summary of the Invention

[0004] This application provides a frame-type device designed to reduce the size of the frame-type device.

[0005] To achieve the above objectives, this application adopts the following technical solution.

[0006] In a first aspect, embodiments of this application provide a frame-type device. The frame-type device includes a frame, a back panel, a fan wall, and multiple service boards. The multiple service boards are located within the frame. The fan wall is located within the frame. All multiple service boards are disposed on the same side of the fan wall; the fan wall has a receiving cavity. The back panel includes a first connector, a cable, and a second connector connected sequentially; the first connector is connected to one of the multiple service boards, and the second connector is connected to another of the multiple service boards; at least a portion of the cable is located within the receiving cavity.

[0007] In this way, by fully utilizing the fan wall's accommodating cavity to house at least a portion of the cable, the length of the cable located between the service board and the fan wall is reduced. The remaining portion of the cable can be accommodated within a smaller distance between the service board and the fan wall. This significantly reduces the space between the fan wall and the service board, making the various structures within the frame more compact and reducing the overall size of the frame-type equipment.

[0008] In conjunction with the first aspect, in some feasible implementations, the width of the receiving cavity is equal to the width of the fan wall. The width of the receiving cavity is maximized. The cable can extend to the end of the fan wall away from the service board, fully utilizing the width dimension of the fan wall and maximizing the reuse of the fan wall's dimensions along the width direction. Even if the cable's bending radius is large, the receiving cavity can provide space for cable bending.

[0009] In conjunction with the first aspect, in some implementable ways, the frame device further includes: a partition, the plurality of service boards located on one side of the partition, the fan wall located on the other side of the partition, and the cables passing through the partition.

[0010] In this way, the partition separates the fan wall from the service board, preventing the fan wall from affecting the service board during insertion and removal. Additionally, the partition restrains the displacement of the fan wall, preventing it from interfering with the service board. It also increases the tidiness of the interior of the chassis-type equipment. With cables passing through the partition, at least a portion of the cables are located within the housing cavity, minimizing the impact of the partition on the full utilization of the housing cavity, and maintaining good integration of the chassis-type equipment.

[0011] In conjunction with the first aspect, in some feasible embodiments, the frame device further includes a cable management rack connected to the cable.

[0012] In this way, the cable management rack can constrain the extension path of cables, making the back panel cleaner. In embodiments where the back panel includes multiple cables, the cable management rack can constrain the extension paths of multiple cables, improving the problem of cable clutter. In addition, the cable management rack can also reduce the space occupied by cables, which helps to reduce the size of the frame-type equipment.

[0013] In conjunction with the first aspect, in some feasible implementations, the cable management rack is located within the receiving cavity. In this way, the cable management rack can constrain the extension path of cables located within the receiving cavity. This can reduce the space required for cables within the receiving cavity, decrease the size of the receiving cavity, and provide more space for other structures within the fan wall (e.g., fans).

[0014] In conjunction with the first aspect, in some feasible ways, the cable management rack is connected to the fan wall. This prevents the cable management rack from moving within the housing cavity, thus preventing cables from moving within the housing cavity and interfering with the operation of other structures within the fan wall (e.g., fans).

[0015] In conjunction with the first aspect, in some feasible embodiments, the fan wall is provided with multiple receiving cavities. Thus, in embodiments where the backplate includes multiple cables, different receiving cavities can accommodate different cables, resulting in a more rational distribution of cables within the fan wall.

[0016] In conjunction with the first aspect, in some feasible implementations, multiple service boards include a first service board and a second service board. The first service board includes a first board body and a first connecting portion connected to each other, the first connecting portion being connected to the first connector; the second service board includes a second board body and a second connecting portion connected to each other, the second connecting portion being connected to the second connector; the distance from the first connecting portion to the fan wall is less than the distance from the second connecting portion to the fan wall.

[0017] Thus, the distances from the end of the multiple service boards closest to the fan wall to the fan wall vary. The distance from the second connection to the fan wall is relatively large, and the space between the second connection and the fan wall can accommodate larger components. For example, a portion of the space-consuming back panel can be accommodated in the space between the second connection and the fan wall. By rationally arranging the space, the space utilization between the service boards and the fan wall can be increased, the compactness of the fan wall, back panel, and multiple service boards can be increased, the integration of the chassis equipment can be increased, and the size of the chassis equipment can be reduced.

[0018] In conjunction with the first aspect, in some implementable methods, the backplane includes a plurality of first connectors, a plurality of cables, and a plurality of second connectors, with each of the first connectors, cables, and second connectors connected in a one-to-one correspondence. The number of first connectors connected to the first connection portion is less than the number of second connectors connected to the second connection portion.

[0019] In this way, the space between the second connection and the fan wall can accommodate the second connector that connects to the second connection. This allows for more space for the second connector that connects to the second connection. By staggering the arrangement of the space between the service boards and the fan wall, the back panel makes full use of the space between the service boards and the fan wall, increasing the integration of the fan wall, back panel, and multiple service boards, and reducing the size of the frame-type equipment.

[0020] In conjunction with the first aspect, in some feasible implementations, the fan frame includes multiple fans, with the receiving cavity located between two of the fans. Thus, the fan wall can cool the service board and backplane, while also providing space for accommodating cables.

[0021] Secondly, this application provides a frame-type device. The frame-type device includes a frame, a back panel, a fan wall, and a first service board and a second service board. The first service board is located within the frame and includes a first board body and a first connecting portion. The second service board is located within the frame and includes a second board body and a second connecting portion. The fan wall is located within the frame; the first service board and the second service board are disposed on the same side of the fan wall. The back panel includes a first connector, a cable, and a second connector connected in sequence; the first connector is connected to the first connecting portion; the second connector is connected to the second connecting portion. The distance from the first connecting portion to the fan wall is less than the distance from the second connecting portion to the fan wall.

[0022] This design allows for a larger space between the first connector and the fan wall, accommodating larger components, such as a greater number of cables in the backplane. Conversely, the space between the second connector and the fan wall is smaller, accommodating fewer cables. The volume of the backplane within both the first and second connector spaces can be adjusted according to the backplane wiring. This results in a more compact arrangement between multiple service boards and the backplane, reducing the overall size of the chassis-type equipment.

[0023] In conjunction with the second aspect, in some implementable embodiments, the backplane includes a plurality of first connectors, a plurality of cables, and a plurality of second connectors, with each of the first connectors, cables, and second connectors connected in a one-to-one correspondence. The number of first connectors connected to the first connection portion is less than the number of second connectors connected to the second connection portion.

[0024] In this way, by arranging the space between the service boards and the fan wall in a staggered manner, the back panel makes full use of the space between the service boards and the fan wall, increases the integration of the fan wall, the back panel and multiple service boards, and reduces the size of the frame equipment.

[0025] In conjunction with the second aspect, in some feasible embodiments, the frame device further includes: a partition, the plurality of service boards located on one side of the partition, the fan wall located on the other side of the partition, and the cables passing through the partition.

[0026] In conjunction with the second aspect, in some feasible embodiments, the frame device further includes a cable management rack connected to the cable.

[0027] In conjunction with the second aspect, in some feasible ways, the cable management rack is connected to the fan wall.

[0028] Regarding the beneficial effects of the second aspect, please refer to the description of any optional implementation method in the first aspect, which will not be repeated here. Based on the implementation methods provided in the above aspects, this application can also be further combined to provide more implementation methods. Attached Figure Description

[0043] Figure 1 This is a schematic diagram of a multi-node interconnection topology. Please refer to [link / reference]. Figure 1 The multi-node interconnected topology includes multiple nodes, such as node A-1, node A-2, node A-3... node AN, and node X-1, node X-2, node X-3... node XM. Here, N is a natural number greater than 3, and M is a natural number greater than 3.

[0044] In this configuration, nodes X-1, X-2, X-3...XM are all connected to node A-1. Nodes X-1, X-2, X-3...XM are all connected to node A-2. Nodes X-1, X-2, X-3...XM are all connected to node A-3, and so on, thus achieving a multi-node interconnection topology.

[0045] Figure 2 This is a schematic diagram of another multi-node interconnection topology. Please refer to [link / reference]. Figure 2 The multi-node interconnected topology includes multiple nodes, such as node A-1, node A-2, node A-3... node AN, and node X-1, node X-2, node X-3... node XM. Here, N is a natural number greater than 3, and M is a natural number greater than 3.

[0046] Figure 2 In this topology, nodes A-2, A-3... AN, X-1, X-2, X-3... XM are all connected to node A-1. Nodes A-1, A-3... AN, X-1, X-2, X-3... XM are all connected to node A-2. Nodes A-1, A-2,... AN, X-1, X-2, X-3... XM are all connected to node A-3. Nodes X-1, X-2, X-3... XM are connected similarly, and so on, thus achieving a multi-node interconnection topology.

[0047] Figure 3 The example above Figure 1 and Figure 2 The diagram shows the interpolation logic of the multi-node interconnection topology. Please refer to [link / reference]. Figure 3Nodes A-1, A-2, A-3... AN, X-1, X-2, X-3... XM are all located in the insertion frame. The connection structure of the aforementioned multi-node interconnection topology is implemented through the system backplane. In other words, the wiring of the aforementioned multi-node interconnection topology is deployed on the system backplane.

[0048] Figure 3 In the middle, a fan wall is also set inside the insertion frame. The fan wall is also used to cool down the aforementioned nodes and prevent high temperature from affecting the normal operation of the aforementioned nodes.

[0049] from Figure 3 As can be seen, the degree of integration of components in the insert frame directly affects the size of the insert frame, and thus the size of the entire device.

[0050] This application provides a frame-type device that has the advantage of small size, reducing the space occupied by the frame-type device. This frame-type device can achieve the aforementioned... Figure 1 or Figure 2 The multi-node interconnected topology is shown. It is understood that the chassis device provided in this application embodiment is not limited to implementing... Figure 1 or Figure 2 The node interconnection architecture shown can also be used for interconnecting other nodes.

[0051] This application does not limit the type of chassis device. For example, a chassis device can be a router or a switch.

[0052] Figure 4 This is a schematic diagram of a frame-type device 100 provided in an embodiment of this application. Please refer to... Figure 4 The frame-type device 100 includes a frame 110, a fan wall 120, a back panel 130, and multiple service boards 140. The fan wall 120, the back panel 130, and the multiple service boards 140 are all located within the frame 110. Figure 4 In the example, the arrangement of multiple service boards 140 can be regarded as a flat insertion, that is, multiple service boards 140 are stacked.

[0053] The backplane 130 includes a first connector 131, a cable 133, and a second connector 132, which are connected sequentially. In other words, the first connector 131 and the second connector 132 are connected to the opposite ends of the cable 133, respectively. The backplane 130 can also be referred to as a cable backplane. The first connector 131 is connected to one of the multiple service boards 140. The second connector 132 is connected to another service board 140 among the multiple service boards 140.

[0054] Multiple service boards 140 are all located on the same side of the fan wall 120, which has a receiving cavity 121. At least a portion of the cable 133 is located within the receiving cavity 121.

[0055] In this way, by fully utilizing the receiving cavity 121 of the fan wall 120 to accommodate at least a portion of the cable 133, the length of the cable 133 located between the service board 140 and the fan wall 120 is reduced. The remaining portion of the cable 133 can be accommodated with a smaller distance between the service board 140 and the fan wall 120. This greatly reduces the space between the fan wall 120 and the service board 140, making the various structures within the frame 110 more compact and reducing the size of the frame-type device 100.

[0056] For example, Figure 4 In this context, d1 represents the distance between the service board 140 and the fan wall 120. Since part or all of the cable 133 connecting the two service boards 140 extends into the receiving cavity 121, the smaller d1 can accommodate the portion of the back panel 130 that does not extend into the receiving cavity 121. The width d2 of the insert frame 110 decreases, and the volume of the frame-type device 100 decreases.

[0057] For ease of description, the width direction of the receiving cavity 121 is defined as the x-direction. In other words, the service board 140 and the fan wall 120 are arranged along the x-direction. The width d2 of the aforementioned insert frame 110 is the dimension of the insert frame 110 along the x-direction. The width direction of the fan wall 120 is also the x-direction.

[0058] In some embodiments, the insert frame 110 may also be referred to as a chassis. The fan wall 120 may also be referred to as a fan frame or fan assembly.

[0059] For example, the service board may include at least one of a computing board, a switching board, an intelligent board, or a storage board. The computing board is used to provide basic processing functions for various services, the switching board is used to provide switching functions between various single boards, the storage board is used to provide storage services, and the intelligent board is used to provide artificial intelligence (AI) intelligent services.

[0060] For example, cable 133 includes a conductive wire and an insulating sleeve, with the insulating sleeve covering the conductive wire. The bending radius of cable 133 affects the space occupied by cable 133. The larger the bending radius of cable 133, the larger the space occupied by cable 133. Conversely, the smaller the bending radius of cable 133, the smaller the space occupied by cable 133.

[0061] The aforementioned "bending radius of cable 133" refers to the inner radius of curvature of the bent portion of cable 133 during the bending process.

[0062] Figure 4In the example, at least a portion of the cable 133 is housed within the receiving cavity 121, and at least a portion of the cable 133 can be bent and wound within the receiving cavity 121. Even if the bending radius of the cable 133 is large, the cable 133 can be housed well.

[0063] The shape of the receiving cavity 121 is not limited in this embodiment, and can be set according to the shape of the fan wall 120 and the bending shape of the cable 133. For example, the receiving cavity 121 can be a cuboid, cylindrical, spherical or irregular shape, etc.

[0064] In some embodiments, the width of the receiving cavity 121 is equal to the width of the fan wall 120. Exemplarily, the dimension of the receiving cavity 121 along the x-direction is equal to the dimension of the fan wall 120 along the x-direction. In other words, the receiving cavity 121 extends from the end of the fan wall 120 near the service board 140 to the end of the fan wall 120 away from the service board 140. In other words, the receiving cavity 121 extends through the fan wall 120 along the x-direction. Thus, the dimension of the receiving cavity 121 along the x-direction is maximized. The cable 133 can extend to the end of the fan wall 120 away from the service board 140, fully utilizing the dimension of the fan wall 120 along the x-direction and maximizing the reuse of that dimension. Even if the bending radius of the cable 133 is large, the receiving cavity 121 can provide space for the bending of the cable 133.

[0065] In other embodiments of this application, the dimension of the receiving cavity 121 along the x-direction may also be smaller than the dimension of the fan wall 120 along the x-direction.

[0066] By way of example, having at least a portion of cable 133 located within receiving cavity 121 includes: a portion of cable 133 being located within receiving cavity 121, and the remaining portion of cable 133 being located outside receiving cavity 121, for example, the remaining portion of cable 133 being located between service board 140 and fan wall 120. Alternatively, the entire cable 133 may be located within receiving cavity 121. First connector 131 and second connector 132 are located between service board 140 and fan wall 120.

[0067] In embodiments of this application, the number of service boards 140 is multiple. For example, the number of service boards 140 can be two, three, four, five, six or more.

[0068] As described above, the first connector 131 is connected to one of the multiple service boards 140, and the second connector 132 is connected to another of the multiple service boards 140.

[0069] The embodiments of this application do not limit the number of first connectors 131 connected to the same service board 140. For example, the number of first connectors 131 connected to the same service board 140 can be two, three, four, five, six or more.

[0070] In some embodiments, the backplane 130 may include a plurality of first connectors 131, a plurality of cables 133, and a plurality of second connectors 132. The plurality of first connectors 131 and the plurality of cables 133 are connected in a one-to-one correspondence, and the plurality of second connectors 132 and the plurality of cables 133 are connected in a one-to-one correspondence.

[0071] In some embodiments, a portion of the cables 133 in the backplate 130 extend into the receiving cavity 121, while a portion of the cables 133 in the backplate 130 do not extend into the receiving cavity 121. Alternatively, in some embodiments, all of the cables 133 in the backplate 130 extend into the receiving cavity 121. This application does not impose any limitations on this.

[0072] Figure 4 In the example, the chassis device 100 may also include a partition 150. The partition 150 is located within the insertion frame 110. Multiple service boards 140 are located on one side of the partition 150, and a fan wall 120 is located on the other side. Cables 133 pass through the partition 150. Thus, the partition 150 separates the fan wall 120 from the service boards 140, preventing the fan wall 120 from interfering with the service boards 140 during insertion and removal. Additionally, the partition 150 can constrain the displacement of the fan wall 120 in the x-direction, preventing the fan wall 120 from interfering with the service boards 140. This increases the tidiness of the interior of the chassis device 100. The cable 133 passing through the partition 150 ensures that at least a portion of the cable 133 is located within the receiving cavity 121, minimizing the impact of the partition 150 on the full utilization of the receiving cavity 121 by the cable 133, and maintaining good integration of the chassis device 100.

[0073] The shape of the partition 150 is not limited in this application embodiment. For example, the partition 150 can be a rectangular plate structure or a curved plate structure.

[0074] In some embodiments, the partition 150 is provided with a plurality of through holes, which allow the cold air output from the fan wall 120 to pass through. In some embodiments, the partition 150 may be a mesh structure, which allows the cold air output from the fan wall 120 to pass through.

[0075] The embodiments of this application do not limit the connection method of the partition 150 and the insert frame 110. For example, the partition 150 and the insert frame 110 can be connected by a weld layer, an adhesive layer or a snap fastener.

[0076] In some embodiments of this application, the partition 150 is not necessary, and the frame device 100 may not have the partition 150.

[0077] Figure 5 for Figure 4 A schematic cross-sectional view of section AA shown. Please refer to... Figure 5 In some embodiments, the chassis device 100 may further include a cable management rack 160 connected to the cables 133. Thus, the cable management rack 160 can constrain the extension paths of the cables 133, making the back panel 130 more streamlined. In embodiments where the back panel 130 includes multiple cables 133, the cable management rack 160 can constrain the extension paths of the multiple cables 133, improving the problem of cable clutter. Furthermore, the cable management rack 160 can reduce the space occupied by the cables 133, which helps to reduce the size of the chassis device 100.

[0078] In some embodiments, the cable management rack 160 is located within the receiving cavity 121. Thus, the cable management rack 160 can constrain the extension path of the cables 133 located within the receiving cavity 121. This reduces the space required for the cables 133 within the receiving cavity 121, decreasing the size of the receiving cavity 121 and providing more space for other structures within the fan wall 120 (e.g., the fan 122).

[0079] For example, the cable management rack 160 is connected to the fan wall 120, so that the cable management rack 160 is fixed relative to the fan wall 120, preventing the cable management rack 160 from moving within the receiving cavity 121. This prevents the cable 133 from moving within the receiving cavity 121 and interfering with the operation of other structures within the fan wall 120 (such as the fan 122).

[0080] For example, the cable management rack 160 and the fan wall 120 can be connected by adhesive layers, solder layers, clips or connecting ropes.

[0081] In some embodiments, the cable management rack 160 is located between the fan wall 120 and the service board 140. Thus, the cable management rack 160 can constrain the extension path of the cables 133 located between the fan wall 120 and the service board 140, preventing the cables 133 between the fan wall 120 and the service board 140 from becoming cluttered and affecting the operation of the fan wall 120.

[0082] In some embodiments, the cable management rack 160 and the partition 150 are connected. This prevents relative movement between the cable management rack 160 and the partition 150. For example, the cable management rack 160 and the partition 150 are connected by an adhesive layer, a solder layer, a clip, or a connecting rope.

[0083] In some embodiments, the cable management rack 160 is partially located within the receiving cavity 121, and the remaining portion of the cable management rack 160 is located between the fan wall 120 and the service board 140.

[0084] The shape of the cable management rack 160 is not limited in this embodiment, and can be set according to the spatial shape of the space used to install the cable management rack 160 and the length and number of cables 133.

[0085] The embodiments of this application do not limit the number of cable management racks 160. For example, the number of cable management racks 160 can be one, two, three, or more. In embodiments where there are multiple cable management racks 160, all of the cable management racks 160 are located within the receiving cavity 121, or all of the cable management racks 160 are located between the fan wall 120 and the service board 140. Alternatively, some of the cable management racks 160 are located within the receiving cavity 121, and some of the cable management racks 160 are located between the fan wall 120 and the service board 140.

[0086] Figure 5 In the example, fan wall 120 includes multiple fans 122, all located within the housing 110. A receiving cavity 121 is located between two adjacent fans 122. Thus, fan wall 120 can cool the service board 140 and backplane 130, while also providing space for accommodating cables 133.

[0087] Figure 5 In the example, the frame device 100 includes a receiving cavity 121. In some embodiments of this application, the frame device 100 may include multiple receiving cavities 121, for example, the frame device 100 may include two, three, four or more receiving cavities 121. Thus, in embodiments where the back panel 130 includes multiple cables 133, different receiving cavities 121 can accommodate different cables 133, making the distribution of cables 133 within the fan wall 120 more rational and efficient.

[0088] Figure 6 This diagram illustrates a vertical projection of the fan wall 120, back panel 130, and multiple service boards 140 onto plane AA. The vertical projection of service board 140 onto plane AA refers to the projection of service board 140 onto plane AA along a direction perpendicular to plane AA. This vertical projection of service board 140 onto plane AA can also be referred to as its orthographic projection. The same logic applies to the vertical projections of service board 140 and back panel 130 onto plane AA. The remaining descriptions of vertical projections in this document are similar and will not be repeated hereafter.

[0089] As described above, the chassis device 100 includes a plurality of service boards 140. Exemplarily, the plurality of service boards 140 includes a first service board 141 and a second service board 142.

[0090] like Figure 6 As shown, the first service board 141 includes a first board body 1411 and a first connecting part 1412 connected together, and the first connecting part 1412 is connected to the first connector 131. The second service board 142 includes a second board body 1421 and a second connecting part 1422 connected together, and the second connecting part 1422 is connected to the second connector 132.

[0091] In this configuration, the distance s1 from the first connecting portion 1412 to the fan wall 120 is less than the distance s2 from the second connecting portion 1422 to the fan wall 120. Thus, the distances from the ends of the multiple service boards 140 closest to the fan wall 120 to the fan wall 120 differ. The distance s2 from the second connecting portion 1422 to the fan wall 120 is larger, allowing for the space between the second connecting portion 1422 and the fan wall 120 to accommodate larger components. For example, a portion of the space-consuming backplane 130 can be accommodated within the space between the second connecting portion 1422 and the fan wall 120. By rationally arranging the space, the space utilization between the service boards 140 and the fan wall 120 can be increased, the compactness of the fan wall 120, the backplane 130, and the multiple service boards 140 can be increased, the integration of the chassis-type equipment can be increased, and the size of the chassis-type equipment can be reduced.

[0092] In some embodiments of this application, the number of cables 133 connected to the first connecting portion 1412 is less than the number of cables 133 connected to the second connecting portion 1422. Thus, the space occupied by the cables 133 connected to the first connecting portion 1412 is less than the space occupied by the cables 133 connected to the second connecting portion 1422. The distance from the service board 140 with a larger number of connected cables 133 to the fan wall 120 is greater than the distance from the service board 140 with a smaller number of connected cables 133 to the fan wall 120. The more cables 133 there are, the larger the bending radius required for multiple cables 133, and the smaller the space occupied by the ends of the cables 133 near the first connecting portion 1412 or near the second connecting portion 1422. Furthermore, because the distance s1 from the first connecting portion 1412 to the fan wall 120 is smaller, the space between the first connecting portion 1412 and the fan wall 120 can accommodate a smaller number of cables 133, while the space between the second connecting portion 1422 and the fan wall 120 can accommodate a larger number of cables 133.

[0093] As described above, the backplate 130 includes a plurality of first connectors 131, a plurality of cables 133, and a plurality of second connectors 132. The number of first connectors 131 connected to the first connection portion 1412 is less than the number of second connectors 132 connected to the second connection portion 1422.

[0094] Thus, the space between the second connection portion 1422 and the fan wall 120 can accommodate the second connector 132 connected to the second connection portion 1422. This provides more space for the second connector 132 connected to the second connection portion 1422. By staggering the arrangement of the space between the service board 140 and the fan wall 120, the back panel 130 makes full use of the space between the service board 140 and the fan wall 120, increasing the integration of the fan wall 120, the back panel 130, and the multiple service boards 140, and reducing the size of the chassis-type equipment.

[0095] In some embodiments of this application, the plurality of service boards 140 may further include a third service board 143. The third service board 143 includes a connected third board body 1431 and a third connecting portion 1432.

[0096] As described above, the first connector 131 is connected to one of the multiple service boards 140, and the second connector 132 is connected to another of the multiple service boards 140. Thus, the third connection part 1432 is connected to the first connector 131, and the second connector 132, which is connected to the first connector 131 via a cable 133, is connected to the second connection part 1422, the first connection part 1412, or another service board 140. In other words, the third service board 143 can be connected to the first service board 141 or the second service board 142 via the cable 133.

[0097] In an embodiment where there are three service boards 140, if the number of cables 133 connected to the first connection part 1412 is less than the number of cables 133 connected to the second connection part 1422, the interconnection scheme of the three service boards 140 can be, for example, that the first service board 141 and the second service board 142 are connected, and the second service board 142 and the third service board 143 are connected. Thus, the number of connectors connected to the first service board 141 is greater than the number of connectors connected to the second service board 142.

[0098] In some embodiments of this application, the plurality of service boards 140 may further include a fourth service board 144, which includes a fourth board body 1441 and a fourth connecting portion 1442. The fourth connecting portion 1442 and the cable 133 are connected via a second connector 132, and the cable 133 is connected to a third connecting portion 1432, a second connecting portion 1422, or a first connecting portion 1412 via a first connector 131. In other words, the fourth service board 144 may be connected to at least one of the first service board 141, the second service board 142, or the third service board 143.

[0099] exist Figure 6 In the example, the distance s4 from the fourth connecting part 1442 to the fan wall 120 is not limited in its relationship with the aforementioned s1 and s2. Furthermore, the distance s3 from the third connecting part 1432 to the fan wall 120 and the distance s4 from the third connecting part 1432 to the fan wall 120 are not limited in their relationship with the aforementioned s1 and s2.

[0100] In some embodiments, the values ​​of s1, s2, s3, and s4 are related to the number of cables 133 connected to each service board 140. For example, the connection with the largest distance to the fan wall 120 among the four connection parts (fourth connection part 1442, third connection part 1432, second connection part 1422, and first connection part 1412) has the most connected cables 133. The connection part with the smallest distance to the fan wall 120 has the fewest connected cables 133.

[0101] It is understood that in some embodiments, the relative sizes of the aforementioned s1, s2, s3, and s4 may be independent of the number of cables 133 connected to each service board 140.

[0102] In embodiments of this application, the distance s1 from the first connecting portion 1412 to the fan wall 120 can be set in various ways. In some embodiments, the position of the first connecting portion 1412 in the x-direction is set by setting the dimension of the first plate 1411 in the x-direction, thereby setting the distance s1 from the first connecting portion 1412 to the fan wall 120. For example, the dimension of the first plate 1411 in the x-direction is greater than the dimension of the second plate 1421 in the x-direction, and the dimension of the first connecting portion 1412 in the x-direction is equal to the dimension of the second connecting portion 1422 in the x-direction; thus, the distance s1 from the first connecting portion 1412 to the fan wall 120 is less than the distance s2 from the second connecting portion 1422 to the fan wall 120. The setting methods for distances s3 and s4 are similar and will not be described in detail here.

[0103] In some embodiments, the distance s1 from the first connecting portion 1412 to the fan wall 120 is set by setting the dimension of the first connecting portion 1412 in the x direction.

[0104] Figure 7 This is a schematic diagram of the fan wall 120, back panel 130, and multiple service boards 140 projected vertically onto the BB plane. Please refer to... Figure 7 The dimension of the first plate 1411 along the x-direction is equal to the dimension of the second plate 1421 along the x-direction. The dimension of the first connecting part 1412 along the x-direction is greater than the dimension of the second connecting part 1422 along the x-direction, such that the distance s1 from the first connecting part 1412 to the fan wall 120 is less than the distance s2 from the second connecting part 1422 to the fan wall 120. The setting methods for distances s3 and s4 are similar and will not be described again here.

[0105] Please return Figure 6 , Figure 6 Only four business boards 140 are shown as examples. It should be noted that this application does not limit the number of business boards 140 to four. Additionally, Figure 6This example only illustrates one interconnection structure for the four service boards 140. In other embodiments, the four service boards 140 can have other interconnection structures. Thus, the backplane 130 for interconnecting the four service boards 140 can have other wiring methods, and this embodiment does not limit this.

[0106] In some embodiments of this application, the distance s1 from the first connecting part 1412 to the fan wall 120 may be equal to the distance s2 from the second connecting part 1422 to the fan wall 120.

[0107] Figure 8 This is a schematic diagram of another vertical projection of the fan wall 120, back panel 130, and multiple service boards 140 onto the AA plane. Please refer to... Figure 8 The distances s1 from the first connecting part 1412 to the fan wall 120, s2 from the second connecting part 1422 to the fan wall 120, s3 from the third connecting part 1432 to the fan wall 120, and s4 from the fourth connecting part 1442 to the fan wall 120 are all equal.

[0108] In the embodiments of this application, the aforementioned s1 equals s2, which allows for the existence of manufacturing and assembly errors. Similarly, s1 equals s3, s1 equals s4, etc., which also allow for the existence of manufacturing and assembly errors, and will not be elaborated here.

[0109] Because at least a portion of the cable 133 in the back panel 130 is located within the receiving cavity 121, even though the distances s1, s2, s3, and s4 are equal. The dimensions of the receiving cavity 121 in the x-direction are reused with those of the back panel 130, increasing the compactness between the back panel 130 and the fan wall 120, which also reduces the size of the frame device.

[0110] In some embodiments of this application, the receiving cavity 121 may not be provided inside the fan wall 120. In other words, the cable 133 may not extend into the fan wall 120.

[0111] Figure 9 This is a schematic diagram of another frame-type device 100 provided in an embodiment of this application. Please refer to... Figure 9 The frame-type device 100 includes a frame 110, a fan wall 120, a back panel 130, and multiple service boards 140. The fan wall 120, the back panel 130, and the multiple service boards 140 are all housed within the frame 110.

[0112] Figure 9 As mentioned above Figure 4 The differences include: the fan wall 120 is not installed. Figure 4 The shown cavity 121. Additionally... Figure 9 In the example, the back panel 130 does not extend into the fan wall 120.

[0113] Figure 9 In the example, the distance from each business board 140 to the fan wall 120 is not exactly the same.

[0114] Figure 10 for Figure 9 A schematic diagram of the vertical projection of the central fan wall 120, back panel 130, and multiple service boards 140 onto the CC plane. Please refer to... Figure 9 The multiple service boards 140 include a first service board 141 and a second service board 142. Both the first service board 141 and the second service board 142 are located in the insert frame 110 (e.g., Figure 9 (as shown) inside.

[0115] The backplane 130 includes a first connector 131, a cable 133, and a second connector 132, which are connected sequentially. The first service board 141 includes a first board body 1411 and a first connecting portion 1412, which is connected to the first connector 131. The second service board 142 includes a second board body 1421 and a second connecting portion 1422, which is connected to the second connector 132.

[0116] Figure 10 In the example, the distance w1 from the first connection 1412 to the fan wall 120 is smaller than the distance w2 from the second connection 1422 to the fan wall 120. Thus, the space between the first connection 1412 and the fan wall 120 is larger, allowing for larger components, such as a greater number of cables 133 in the backplane 130. Correspondingly, the space between the second connection 1422 and the fan wall 120 is smaller, accommodating a smaller number of cables 133. The volume of the backplane 130 within the spaces between the first connection 1412 and the fan wall 120, and between the second connection 1422 and the fan wall 120, can be adjusted according to the wiring of the backplane 130. This makes the multiple service boards 140 and the backplane 130 more compact, reducing the size of the chassis device 100.

[0117] In some embodiments of this application, the number of first connectors 131 connected to the first connecting portion 1412 is less than the number of second connectors 132 connected to the second connecting portion 1422. Thus, the larger space between the first connecting portion 1412 and the fan wall 120 accommodates a larger number of first connectors 131, while the smaller space between the second connecting portion 1422 and the fan wall 120 accommodates a smaller number of second connectors 132. This rationally distributes the space between the multiple service boards 140 and the fan wall 120, reducing the volume between the service boards 140 and the fan wall 120, increasing the integration of the chassis-type device, and reducing the overall size of the chassis-type device.

[0118] In some embodiments of this application, such as Figure 10As shown, the multiple service boards 140 may further include a third service board 143 and a fourth service board 144. The structures of the third service board 143 and the fourth service board 144 are described above. Figure 6 The description in the text will not be repeated here.
