Detailed Description

The embodiments of the present application will be further described with reference to the accompanying drawings.

The communication equipment provided by the embodiment of the application is applied to a common communication system.

The communication equipment provided by the embodiment of the application can be applied to a communication base station, a data center and other scenes needing an application cabinet. In the above scenarios, a communication device is required, and the existing communication device is shown in fig. 1. The communication device includes a subrack 1 and a backplane 2 disposed on the subrack 1. The back plate 2 and the machine frame 1 are fixedly connected through bolts or screws. If a connector on the backplane 2 fails or if the backplane 2 signal rate or infrastructure is upgraded due to equipment requirements, the entire backplane 2 must be replaced. The existing assembly mode of the back panel 2 and the machine frame 1 causes that the communication equipment cannot be conveniently maintained or upgraded. In addition, as can be seen from fig. 1, when the backplane 2 is assembled on the machine frame 1, the side of the backplane 2 with the larger size faces the inside of the machine frame 1, and ventilation can only be performed through the hollow structures 3 on the backplane 2 during heat dissipation, which is not beneficial to ventilation and heat dissipation of the communication equipment. Therefore, the communication equipment is provided by the embodiment of the application and is used for facilitating the maintenance or the upgrade of the communication equipment and improving the heat dissipation effect. The following detailed description is given with reference to the accompanying drawings and examples.

Fig. 2 shows a block diagram of a communication device according to an embodiment of the present application. The communication device provided by the embodiment of the present application includes a subrack 10 and a backplane 20. Subrack 10 serves as a load-bearing structure for carrying backplane 20 and other components. The back plate 20 and the machine frame 10 are fixed in a plug-in connection mode, so that the back plate 20 is convenient to disassemble. The backplane 20 serves as a patch panel for patching signals from a board (not shown). In use, the board may be inserted into subrack 10 and coupled to backplane 20. Backplane 20 transmits signals or electrical current on the board to other devices via connected cables.

The machine frame 10 includes a first side plate 11, a second side plate 13, a third side plate 12, and a fourth side plate 14, the first side plate 11, the second side plate 13, the third side plate 12, and the fourth side plate 14 are connected end to form a frame-shaped structure, and the frame-shaped structure has a space for accommodating the backplane 20 and the insert board. Frame 10 is open at both ends, designated first and second ports, respectively, for convenience of description. Backplane 20 may be inserted into subrack 10 from the second port and the card may be inserted into subrack 10 from the first port when backplane 20 and card are assembled within subrack 10. The space of the machine frame 10 for accommodating the insert plate and the back plate 20 can also be used as an air duct, an air inlet of the air duct is a first port, and an air outlet of the air duct is a second port. When the backplane 20 and the board are inserted into the frame 10, the backplane 20 and the board are both located in the air duct. When air circulates in the ventilation duct, the heat of the backboard 20 and the inserting plate can be dissipated.

To facilitate the description of the relative positions of the frame 10 and the backplane 20, an XYZ coordinate system is established, wherein the X direction, the Y direction, and the Z direction are respectively parallel to three adjacent sides of the frame 10. The ventilation direction of the air duct of the machine frame 10 is in the Y direction. The resting surface of the subrack 10 is parallel to the XY-plane. The above-mentioned placing surface is a surface parallel to the ground plane when the communication device is placed.

The number of the back plates 20 can be different, such as one, two, three, etc. different numbers of the back plates 20. When the communication equipment needs to be upgraded, the number of the back boards 20 can be increased for upgrading. As shown in fig. 2, when the number of the back plates 20 is plural, the plural back plates 20 are arranged in a single row, and the arrangement direction (X direction) is perpendicular to the ventilation direction.

When backplane 20 is secured within subrack 10, backplane 20 is positioned adjacent to the second port. During plugging, backplane 20 may be inserted into subrack 10 from the second port and fixedly connected to subrack 10. Illustratively, subrack 10 is provided with a plurality of slots, and each backplane 20 is removably secured within one of the slots. The slots are arranged on two opposite side plates of the machine frame 10, and when the back plate 20 is fixed in the machine frame 10 in the manner shown in fig. 2, the slot bodies of the slots are respectively arranged on the inner walls of the first side plate 11 and the third side plate 12. The two ends of the back plate 20 can be inserted into the grooves of the first side plate 11 and the second side plate 13 respectively.

When the backplane 20 is inserted to the set position, the backplane 20 may be locked in the subrack 10 by a locking member to achieve a fixed connection of the backplane 20 and the subrack 10. The locking part can adopt a common fastener, a locking screw or a bolt and the like. Taking the locking member as an example of a snap, a snap is provided on one of the back plate 20 or the frame 10, and a slot is provided on the other. When the backplane 20 is inserted into a set position in the machine frame 10, the latch engages with the slot, thereby locking the backplane 20 in the machine frame 10 and achieving a fixed connection therebetween. When the backboard 20 needs to be pulled out, the locking piece can be unlocked, and the backboard 20 can be directly pulled out from the machine frame 10. Compare the connection of backplane 20 to subrack 10 shown in FIG. 1. The backplate 20 that this application embodiment provided adopts plug connection and through the mode of retaining member locking with the mechanism, has made things convenient for the dismantlement of backplate 20, when maintenance backplate 20, only need with the backplate 20 that breaks down extract can, need not to take off other backplate 20.

When the slots are arranged, the number of the slots is multiple, and the slots are arranged along the X direction. When the communication device is used, the required number of backplanes 20 can be assembled according to the requirement, and each backplane 20 is inserted into one of the slots. It should be understood that the number of slots provided in subrack 10 is greater than or equal to the number of backplanes 20. If the number of the slots is larger than that of the backboard 20, the space for inserting the backboard 20 is reserved for upgrading the communication equipment. Illustratively, when the communication device is designed, a chassis 10 is provided with N slots, M backplanes 20 are inserted into the N slots, and N-M slots are left unused on the chassis 10; wherein N is a positive integer greater than M, and M is a positive integer greater than or equal to 1. When the communication device needs to be upgraded in the using process, more backplanes 20 can be inserted into the idle N-M slots to upgrade and expand the communication device.

To facilitate the description of the state of the backplane 20 inside the subrack 10, a first installation surface of the backplane 20 is defined. The first mounting surface is a surface of the backplate 20 on which devices, such as capacitors, inductors, and first connectors 30, are mounted.

When the backplane 20 is inserted into the subrack 10, the first setting surface is parallel to the ventilation direction of the air duct, and as shown in fig. 2, the first setting surface is parallel to the YZ plane. Referring to the arrowed lines shown in fig. 2, the arrowed lines indicate the flow direction of air in the air duct. When the air flows in the ventilation duct, the side face with the smaller size of the back plate 20 faces the first port, and the first arrangement face with the larger size of the back plate 20 is parallel to the flow direction of the air, so that the resistance when the air flows is reduced, and the ventilation effect of the communication equipment is improved. In addition, when the air flows, the air flows through the first setting surface, so that heat generated by devices arranged on the first setting surface can be taken away, and the heat dissipation effect is improved.

In order to facilitate understanding of the ventilation effect of the communication device provided by the embodiment of the present application, two communication devices shown in fig. 2 and fig. 1 are compared. As can be seen from the structure shown in fig. 1, when the back plate 20 is connected to the frame 10 in the manner shown in fig. 1, air can only ventilate through the hollow structures on the back plate 20, but as more devices are mounted on the back plate 20, the number of areas on the back plate 20 that can be hollow is less, and the ventilation effect is worse. In addition, the surface of the back plate 20 on which the device is disposed faces the flowing direction of air, and the air is directly blown to the surface, and then the back plate needs to be bent to take away the heat generated by the device, which is also not beneficial to heat dissipation. In the communication device provided in the embodiment of the present application, since the side surface of the back plate 20 faces the first port, air can pass through the gap between the back plates 20 for ventilation, and the arrangement of the devices on the back plate 20 does not affect the ventilation effect. In addition, the first arrangement surface is parallel to the flowing direction of the air, the flowing direction of the air does not need to be changed when the air can flow through the first arrangement surface, and the effect of taking away heat generated by a device is improved.

With continued reference to fig. 2, the first arrangement surface of each backplane 20 is provided with a plurality of first connectors 30, and the plurality of first connectors 30 are used for connecting with the second connectors 50 on the card. When backplane 20 is inserted into subrack 10, the connection ends of plurality of first connectors 30 face the air inlet of the air duct, i.e. the connection ends of first connectors 30 face the first port. Second connector 50 may be connected to first connector 30 when the card is inserted into subrack 10 from the first port in the Y-direction, enabling the card to be connected to backplane 20.

The plurality of first connectors 30 of each backplane 20 are arranged in a single row along the first direction (Z direction). When multiple backplanes 20 are located in subrack 10, the first connectors 30 of all backplanes 20 are arranged in an array to facilitate an aligned connection with the second connectors 50 of the card.

Referring to FIG. 3, FIG. 3 shows a schematic view of the insertion of card 40 into subrack 10. The plug-in board 40 can be connected with the machine frame 10 in a plugging mode, and when the plug-in board 40 is inserted into the machine frame 10, the plug-in board 40 is connected with the back board 20 in a signal mode.

For convenience of description of the relative position of the interposer 40 and the frame 10, a second mounting surface of the interposer 40 is defined, and the second mounting surface is a surface on which devices, such as capacitors, inductors, and the second connector 50, are mounted on the interposer 40. When the inserting plate 40 is inserted into the machine frame 10, the second setting surface is parallel to the ventilation direction of the ventilation duct, the second setting surface is perpendicular to the first setting surface, and when the first setting surface is parallel to the YZ plane, the second setting surface is parallel to the XY plane.

Referring also to fig. 4, fig. 4 shows a schematic view of the mating of the backplane 20 with the interposer 40. Card 40 has opposite first and second ends, where the first end is the end of card 40 adjacent the first port when inserted into frame 10 and the second end is the end of card 40 adjacent the second port when inserted into frame 10. The second setting surface of the card 40 is provided with a second connector 50 for mating with the first connector 30, the second connector 50 being provided at a second end of the card 40. The number of the second connectors 50 is plural, and the plural second connectors 50 are arranged in a single row along the X direction. The plurality of second connectors 50 on each card 40 are aligned with a row of first connectors 30 in the array of first connectors 30 when each card 40 is inserted into subrack 10. The row of first connectors 30 refers to a row of connectors arranged along the X direction. As can be seen from the above description, when the plug board 40 is inserted into the back boards 20, the plug board 40 is correspondingly connected to one first connector 30 of each back board 20, and the plug and pull connection between the plug board 40 and the back board 20 is realized through the plug and pull connection between the second connector 50 and the first connector 30.

When the inserting plate 40 is matched with the machine frame 10, a sliding groove is arranged in the machine frame 10, and the inserting plate 40 can be assembled in the sliding groove in a sliding mode and can be locked at a set position. When the insert plates 40 are arranged in the manner shown in fig. 3, the slide grooves are formed on the inner walls of the second side plate 13 and the fourth side plate 14 which are opposite to each other. When the inserting plate 40 is inserted into the frame 10 along the sliding slot, the aligning device can perform precise alignment to ensure that the second connector 50 can be accurately connected with the first connector 30. Illustratively, the alignment means may include alignment posts provided in one of the back plate 20 or the insert plate 40 and alignment holes provided in the other of the back plate 20 or the insert plate 40. When card 40 is inserted into frame 10, the alignment posts and alignment holes are positioned opposite each other. With the insertion of the insertion board 40, the alignment posts are inserted into the alignment holes to achieve precise alignment of the second connector 50 with the first connector 30.

When the inserting plate 40 is inserted into the machine frame 10, the inserting plate 40 can be locked, and the specific locking manner can refer to the locking manner of the back plate 20, which is not described herein again.

It should be understood that, in the communication device provided in the embodiment of the present application, the card 40 may also be a component of the communication device. When a communication device is upgraded, the corresponding card 40 also needs to be upgraded. Illustratively, as the number of backplanes 20 provided in subrack 10 increases, it may be necessary to replace card 40 so that the number of second connectors 50 on card 40 matches the number of first connectors 30 in a row.

When the inserting plate 40 and the back plate 20 are fixed in the machine frame 10, the inserting plate 40 and the back plate 20 are positioned in the ventilating duct in a crisscross manner, the ventilating duct is divided into grids by the inserting plate 40 and the back plate 20, and the first arrangement surface and the second arrangement surface of the inserting plate 40 and the back plate 20 are both parallel to the ventilating direction, so that the influence on the ventilating duct is reduced. When flowing, the air can flow through the components on the inserting plate 40 and the back plate 20 in sequence, and the heat dissipation effect of the inserting plate 40 and the back plate 20 is increased.

Referring to fig. 5, fig. 5 shows a schematic structural diagram of a communication device according to an embodiment of the present application. Reference may be made to some of the reference numerals in fig. 5 to those shown in fig. 3. The communication device shown in fig. 5 differs from the communication device shown in fig. 3 only in the way in which the back plate 20 is arranged.

When the backplates 20 are arranged, each backplane 20 is arranged with a first arrangement surface parallel to the XY plane, i.e. the first arrangement surface is parallel to the placing surface of the subrack 10. When the plurality of backplates 20 are arranged, the arrangement direction of the backplates 20 is parallel to the placing surface of the machine frame 10, that is, the plurality of backplates 20 are arranged at intervals along the Z-direction.

When the back board 20 is arranged in the manner shown in fig. 5, the slots of the machine frame 10 are correspondingly disposed on the inner side walls of the second side board 13 and the fourth side board 14. The two ends of the back plate 20 are respectively slidably fitted in the slots and locked by the locking members when inserted to a set position, so as to realize the relative fixation of the back plate 20 and the machine frame 10.

Referring to fig. 6, when the board 50 is inserted into the backplane 20, the board 50 is arranged in a direction perpendicular to the mounting surface of the frame 10. Wherein, when each board 50 is inserted, the second setting surface is perpendicular to the XY plane, i.e. perpendicular to the placing surface of frame 10. When the plurality of insert plates 50 are arranged, the plurality of insert plates 50 are arranged at intervals in the X direction.

When the communication device shown in fig. 5 is used, the same effects as those of the communication device shown in fig. 3 can be achieved, and the details are not repeated herein.
