The communication board is provided with a guide rail on the module rail overhead. The pluggable module can be inserted into the communication board through the guide rail.
[0003] In practical applications, the space utilization rate of communication boards is not high. Summary of the invention
[0004] The present application provides a communication board and a communication device, which can improve the space utilization of the communication board by reusing a support body and a guide rail of a pluggable module.
[0005] The first aspect of the present application provides a communication board. The communication board includes a cover plate, a PCB, two support bodies and a pluggable module. The cover plate and the PCB are parallel and spaced apart. The cover plate and the PCB are perpendicular to the Y-axis direction. Each of the two support bodies is used to connect the cover plate and the PCB to fix the cover plate and the PCB. There is a gap between the two support bodies in the X-axis direction. The X-axis direction is perpendicular to the Y-axis direction. An internal space is formed between the two support bodies, the cover plate and the PCB. Each of the two support bodies includes a first guide rail. The direction of the first guide rail is the Z-axis direction. The Z-axis direction is perpendicular to the Y-axis direction and the X-axis direction. The pluggable module serves as a slider of the first guide rail. The pluggable module is arranged in the internal space through the first guide rail and is connected to the PCB.
[0006] In an optional manner of the first aspect, both sides of the cover plate include upper rails parallel to the Z-axis direction. The projections of the two support bodies on the cover plate along the Y-axis direction and the upper rails have overlapping areas. By reusing the space of the support body and the upper rails in the X-axis direction, the space utilization rate of the communication board can be improved.
[0007] In an optional manner of the first aspect, the communication board also includes a protective plate. The PCB is between the protective plate and the cover plate. The protective plate includes a lower guide rail parallel to the Z-axis direction at a position corresponding to the upper guide rail. There is an overlapping area between the projections of the two support bodies on the protective plate along the Y-axis direction and the lower guide rail. Wherein, a guide rail is provided on the communication device, and the communication board serves as a target slider, and the target slider matches the guide rail on the communication device. The upper guide rail and the lower guide rail are respectively part of the target slider. For example, when the protrusion of the target slider matches the guide rail on the communication device, the upper guide rail refers to one side of the protrusion, and the lower guide rail refers to the other side of the protrusion. In the present application, by reusing the space of the support body and the lower guide rail in the X-axis direction, the space utilization rate of the communication board can be improved.
[0008] In an optional manner of the first aspect, the maximum distance between the two support bodies in the X-axis direction is greater than the length of the cover plate in the X-axis direction. The two support bodies are provided with upper guide rails parallel to the Z-axis direction. By multiplexing the support bodies and the upper guide rails, the space utilization rate of the communication board can be improved.
[0009] In an optional manner of the first aspect, the communication board further includes a protective plate. The PCB is between the protective plate and the cover plate. The length of the protective plate in the X-axis direction is greater than the length of the cover plate in the X-axis direction. The protective plate is provided with a lower guide rail at a position corresponding to the upper guide rail. By providing the lower guide rail on the protective plate, the width of the PCB in the X-axis direction can be wider, thereby improving the space utilization of the communication board.
[0010] In an optional manner of the first aspect, each of the two supporting bodies is fixed by the first region and the PCB. The projection of the first region on the protective plate along the Y-axis direction and the lower guide rail have an overlapping area. By reusing the space of the first region and the lower guide rail in the X-axis direction, the available space of the PCB can be increased.
[0011] In an optional manner of the first aspect, the communication board further includes a protective plate, and the PCB is between the protective plate and the cover plate. The maximum distance between the two support bodies in the X-axis direction is greater than the length of the protective plate in the X-axis direction. The two support bodies are provided with lower guide rails parallel to the Z-axis direction. By providing the lower guide rails on the support bodies, the width of the protective plate in the X-axis direction can be narrower, thereby reducing the hardware cost of the communication board.
[0012] In an optional manner of the first aspect, the first guide rail includes an upper guide rail and a lower guide rail. The pluggable module includes an upper module and a lower module. The upper module serves as a slider of the upper guide rail. The upper module is arranged in the internal space by matching the upper guide rail. The lower module serves as a slider of the lower guide rail. The lower module is arranged in the internal space by the lower guide rail. By providing the upper guide rail and the lower guide rail, the communication board can be configured with more pluggable modules, thereby improving the space utilization of the communication equipment.
[0013] In an optional manner of the first aspect, the communication board further includes two inner guide rails. The pluggable module includes a left module and a right module. The two inner guide rails are between the left module and the right module. By providing the inner guide rails, the communication board can be configured with more pluggable modules, thereby improving the space utilization of the communication device.
[0014] In an optional manner of the first aspect, the material of the two supports is zinc or plastic. In practical applications, the supports are used to fix the cover plate and the PCB. The material of the support is generally iron. However, in the present application, the support is used to fix the cover plate and the PCB, and is also used as the first guide rail. Therefore, the support not only requires a certain rigidity, but also requires convenience in processing the guide rail. By using zinc or plastic as the material of the support, the cost of processing the guide rail can be reduced, thereby reducing the processing cost of the communication board.
[0015] In an optional manner of the first aspect, the difference between the length of the PCB in the X-axis direction and the total width of the pluggable module in the X-axis direction is less than or equal to 25 mm. In practical applications, the non-overlapping area of the PCB and the pluggable module in the X-axis direction is used as the single board guide rail overhead, the support column overhead and the module guide rail overhead. The three overheads result in a larger width of the non-overlapping area. In the present application, by multiplexing the support body and the guide rail, that is, multiplexing the support column overhead and the guide rail overhead of the pluggable module, the width of the non-overlapping area can be reduced, thereby improving the space utilization of the communication single board.
[0016] In an optional manner of the first aspect, the first guide rail is a groove on two support bodies. The length of each of the two support bodies at the groove along the X-axis direction is greater than or equal to 3 mm. In the present application, the support body is used to fix the cover plate and the PCB, and is also used as the first guide rail. By controlling the length of the support body at the groove, the structural stability of the communication board can be improved.
[0017] In an optional manner of the first aspect, the pluggable module includes an optical power amplifier module.
[0018] The second aspect of the present application provides a communication device. The communication device includes a power supply module and the communication board described in the first aspect or any optional manner of the first aspect. The power supply module is used to power the communication board. The communication board is used to receive a signal, process the received signal, and output the processed signal.

[0028] The present application provides a communication board and a communication device, which can improve the space utilization of the communication board by reusing the guide rails of the support body and the pluggable module. It should be understood that the "first", "second", etc. used in the present application are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order. In addition, for the sake of simplicity and clarity, reference numbers and / or letters are repeated in multiple figures of the present application. Repetition does not indicate that there is a strict limiting relationship between various embodiments and / or configurations.
[0029] The communication board provided in the present application is applied to the communication field. In the communication field, service data processing and communication can be performed through the communication board. A communication board refers to a collection of electronic devices, chips, and plug-in accessories that provide service ports. The space of the communication board is divided into the layout space of the board guide rail overhead, the support column overhead, the module guide rail overhead, and the pluggable module in the width direction, resulting in low space utilization of the communication board.
[0030] To this end, the present application provides a communication board. The communication board can be a service board, a switching board or a control board. The service board includes a branch board or a line board. Among them, the branch board is used to realize the reception and transmission of various customer services, such as synchronous digital hierarchy (SDH) services, packet services, Ethernet services and / or fronthaul services. Further, the branch board can be divided into a client-side optical transceiver module and a signal processor. Among them, the client-side optical transceiver module can also be called an optical transceiver, which is used to receive and / or send service signals. The signal processor is used to realize the mapping and demapping processing of service signals to data frames. The line board mainly realizes the processing of line-side data frames. Specifically, the line board can be divided into a line-side optical module and a signal processor. Among them, the line-side optical module can be called an optical transceiver, which is used to receive and / or send service signals. The signal processor is used to realize the multiplexing and demultiplexing of the service signals on the line side, or the mapping and demapping processing. The switching board is also called a switching mesh or a cross board, which is used to realize information exchange between different service boards. The control board is used to implement system control. Specifically, the control board is used to collect information from different service boards, or send control instructions to the corresponding service boards. It should be noted that in a specific implementation, the branch board and the line board may also be designed as one board. In this case, the communication board includes the branch board and the line board.
[0031] Figure 1 This is a first structural diagram of a communication board provided in an embodiment of the present application. Figure 1As shown, the communication board includes a cover plate 101, a printed circuit board (PCB) 102, two support bodies (103 and 104) and a pluggable module 105. Among them, the cover plate 101 and the PCB 102 are parallel and spaced apart. The cover plate 101 and the PCB 102 are perpendicular to the Y-axis direction. The cover plate 101 is used to protect the PCB 102 or the device connected to the PCB 102, such as the pluggable module 105. It should be understood that due to the existence of processing errors, the cover plate 101 and the PCB 102 cannot be completely parallel. Therefore, in this application, when the angle between the cover plate 101 and the PCB 102 is less than 5°, it is characterized that the cover plate 101 and the PCB 102 are parallel. The material of the two support bodies is zinc, plastic, aluminum or iron, etc. Each of the two support bodies is used to connect the cover plate 101 and the PCB 102 to fix the cover plate 101 and the PCB 102. There is a gap between the two support bodies in the X-axis direction. The X-axis direction is perpendicular to the Y-axis direction. An internal space is formed between the two support bodies, the cover plate 101 and the PCB 102. Each of the two support bodies includes a first guide rail. Figure 1 In the example, the support body 103 is provided with a groove 106. The groove 106 is used as a first guide rail. The direction of the first guide rail is the Z-axis direction. The Z-axis direction is perpendicular to the Y-axis direction and the X-axis direction. The pluggable module 105 serves as a slider of the first guide rail. Figure 1 In the example of FIG. 1 , a protrusion is provided on the pluggable module 105. The size of the protrusion matches the size of the groove 106. The pluggable module 105 is arranged in the internal space through the first guide rail and is connected to the PCB 102. For example, the pluggable module 105 and the PCB 102 are assembled in parallel. The pluggable module 105 and the PCB 102 are connected to each other through a connector. One end of the connector is connected to a connection port on the pluggable module 105. The other end of the connector is connected to a connection port on the PCB 102.
[0032] In the embodiment of the present application, the pluggable module 105 is an optical power amplification module or a function expansion module, etc. The function expansion module can be a service interface module, a wavelength conversion module or a wavelength selection module, etc. The pluggable module 105 can include a plurality of parallel modules. Modules in different columns can be the same or different modules. Figure 2a This is a front view of the communication board provided in an embodiment of the present application. Figure 2b This is a cross-sectional top view of a communication board provided in an embodiment of the present application. Figure 2a and Figure 2b As shown, in Figure 1On the basis of, the communication board also includes two inner guide rails (inner guide rail 203 and inner guide rail 204 respectively). The direction of the two inner guide rails is the Z-axis direction. The two inner guide rails are parallel to each other and parallel to the first guide rail. The two inner guide rails are fixed on the PCB 102. The pluggable module 105 includes a left module 201 and a right module 202. The two inner guide rails are between the left module 201 and the right module 202. The left module 201 serves as a slider for the inner guide rail 203 and the first guide rail on the support body 103. The right module 202 serves as a slider for the inner guide rail 204 and the first guide rail on the support body 104.
[0033] In the technical solution provided in the embodiment of the present application, by reusing the guide rails of the support body and the pluggable module, the total width of the pluggable module in the X-axis direction can be increased. At this time, the difference between the length d2 of the PCB 102 in the X-axis direction and the total width d1 of the pluggable module in the X-axis direction will be reduced. When the difference is smaller, the space utilization rate of the communication board is higher. In the embodiment of the present application, the difference between d2 and d1 can be less than or equal to 25 mm. For example, when d2 is equal to 198.5 mm, d1 can be 174.8 mm or 184.3 mm.
[0034] In an embodiment of the present application, the support body is used to fix the cover plate 101 and the PCB 102, and is also used as a guide rail for the pluggable module. Therefore, the support body will affect the structural stability of the communication board. In practical applications, the structural stability of the communication board can be improved by controlling the length of the support body in the X-axis direction. For example, the minimum length of the support body in the X-axis direction is greater than or equal to 3 mm. Among them, when the groove on the support body serves as the first guide rail and the protrusion of the pluggable module matches the first guide rail, the minimum length of the support body in the X-axis direction refers to the length d3 of the support body at the groove.
[0035] exist Figure 1 , Figure 2a or Figure 2b In the example of FIG. 1 , the communication board includes a cover plate 101. The cover plate 101 can be used to protect one plane of the PCB 102 and / or the pluggable module 105. In practical applications, the communication board can also include a protective plate. The protective plate is used to protect another plane of the PCB 102. Figure 3 This is a second structural diagram of a communication board provided in an embodiment of the present application. Figure 3 As shown, in Figure 2a On the basis of, the communication board further includes a protection board 301 and an isolator 302. The isolator 302 is used to isolate the protection board 301 and the PCB 102, so that there is a gap between the protection board 301 and the PCB 102 in the Y-axis direction. Figure 3In the embodiment, the protection plate 301 is used to protect the second plane 304 of the PCB 102. The cover plate 101 is used to protect the first plane 303 of the PCB 102 and / or the pluggable module 105.
[0036] In actual applications, in order to facilitate the replacement of communication boards in communication equipment, a guide rail is provided on the communication equipment. At this time, the communication board serves as a target slider, and the target slider matches the guide rail on the communication equipment. The communication board can be inserted into the guide rail of the communication equipment as a slider. The target slider includes an upper guide rail and a lower guide rail. The upper guide rail and the lower guide rail refer to a part of the target slider, respectively. For example, when the protrusion of the target slider matches the guide rail on the communication equipment, the upper guide rail refers to one side of the protrusion, and the lower guide rail refers to the other side of the protrusion. Figure 4 This is a third structural diagram of a communication board provided in an embodiment of the present application. Figure 4 As shown, in Figure 3 On the basis of, the cover plate 101 and the protective plate 301 extend to both sides. The extended part of the cover plate 101 serves as the upper guide rail 403 of the communication board. The extended part of the protective plate 301 serves as the lower guide rail 404 of the communication board. The upper guide rail 403 and the lower guide rail 404 are parallel to the Z-axis direction. Figure 4 In the embodiment, the cover plate 101 and the two supporting bodies are connected by a connecting piece 401; the protection plate 301 and the PCB 102 are connected by a connecting piece 402. Figures 1 to 4 In the example, by reusing the support and the rails of the pluggable module, the space utilization of the communication board can be improved. In practical applications, the space of the support and the rails of the communication board in the X-axis direction can also be reused, thereby improving the space utilization of the communication board. Figure 5 This is a fourth structural diagram of a communication board provided in an embodiment of the present application. Figure 5 As shown, in Figure 4 On the basis of, by moving the two supports to the sides, the space of the support and the rail of the communication board in the X-axis direction can be reused. Among them, the support 103 moves in the negative direction of the X-axis, and the support 104 moves in the positive direction of the X-axis.

In practical applications, the support body can also serve as the upper guide rail 403 of the communication board. Figure 6 This is a fifth structural diagram of a communication board provided in an embodiment of the present application. Figure 6 As shown, in Figure 4On the basis of, the two support bodies are extended to both sides so that the maximum distance between the two support bodies in the X-axis direction is greater than the length of the cover plate 101 in the X-axis direction. The extended part of the support body serves as the upper guide rail 403 of the communication board. Among them, the support body 103 extends in the negative direction of the X-axis, and the support body 104 extends in the positive direction of the X-axis. Figure 6 In the embodiment, each of the two supporting bodies is fixed by the first area and the PCB 102. For example, the supporting body is fixed by the screw 402 and the PCB 102. The first area is the projection area of the screw 402 on the supporting body along the Y-axis direction. In order to allow the PCB 102 to have more space in the X-axis direction, the distance between the first areas can be as large as possible. For example, the projection of the two first areas on the protective plate 301 along the Y-axis direction and the lower guide rail 404 have an overlapping area.
[0038] exist Figure 6 In the example, the protection plate 301 serves as the lower guide rail 404 of the communication board. In practical applications, the support body can also serve as the lower guide rail 404 of the communication board.
