Description

Technology Field

[0001] This application claims priority to Chinese Patent Application No. 202010480697.2 ('Board-level architecture and communication device'), filed with the Chinese Intellectual Property Office on May 30, 2020, the entirety of which is incorporated herein by reference.

[0002] This application relates to the field of communication technology, specifically to board-level architecture and communication devices. Background Technology

[0003] In a communication system, different boards implement signal connection and communication through connectors. In current common communication systems, vertical orthogonality is a form of common orthogonal architecture. A large number of connectors are used in the system to implement the insertion, removal, and replacement of boards. FIG. 1 is a schematic diagram of a simple communication system. When board (1) communicates with board (2), both connector (1) and connector (2) are press-fitted directly to different boards and then fitted together to implement the transmission of a signal channel.

[0004] In such a system, as the number of boards (2) increases, the size of the board (1) becomes larger. Consequently, it becomes more difficult to process the board (1). Additionally, as the signal transmission speed increases, the electrical signal loss increases as the size of the board (1) increases. To address the problem of increased electrical signal loss, two main solutions are currently being used. One method is to add a signal amplifier to the board (1), but the implementation of the board (1) is complex and costly. Another method is to use wires / cables with better signal transmission quality, and this method is also a future development trend. However, when wires / cables are used to transmit signals, connectors between boards are added. If different types of connectors are placed on the board (2), implementing connections between boards is cumbersome. The technology forming the background of this application is disclosed in U.S. Patent Application Publication US 2013 / 107489 A1 (May 2, 2013).

[0005] The present application provides a board-level architecture and a communication device, which can simplify the connection of the board-level architecture and increase the flexibility of the board-level architecture during configuration.

[0006] According to the first aspect, a board-level architecture is provided, the board-level architecture comprises a support board, a switch board, and a press-fit assembly, the press-fit assembly being configured to implement an electrical connection between the assemblies. The press-fit assembly comprises a cable, a first connector assembly pressed into a side edge of the support board, and a second press-fit cable connector pressed into a side edge of the switch board. The first connector assembly comprises a first press-fit cable connector and a pluggable connector electrically connected to the first press-fit cable connector, the pluggable connector being located further away from the support board than the first press-fit cable connector. The first press-fit cable connector is connected to the second press-fit cable connector via a cable. In use, the pluggable connector is configured to be electrically connected to a connector on another board to implement a communication connection between the switch board and the other board. Therefore, since it is sufficient for the pluggable connector to be matched with the connector of another board, and the first press-fit cable connector and the second press-fit cable connector can be separated from the connector of another board, and since the first press-fit cable connector and the second press-fit cable connector can each be different types of connectors, the flexibility of the board-level architecture can be increased during configuration. In addition, the second press-fit cable connector can be electrically connected directly to the switch board without the need to place a connector corresponding to the second press-fit cable connector, thereby simplifying the structure of the board-level architecture.

[0007] In a specific feasible solution, the adapter is placed on a support board, and the first press-fit cable connector and the pluggable connector are each press-fitted onto two surfaces opposite each other of the adapter.

The second connector assembly comprises a second pluggable connector pressed onto the first surface and a second press-fit cable connector pressed onto the second surface, and the second press-fit cable connector is electrically connected to the second pluggable connector. The first press-fit cable connector is connected to the second press-fit cable connector via a cable. In the above-described solution, the first pluggable connector and the second pluggable connector are connected to a switch board and a service board, respectively. Therefore, since the two pluggable connectors only need to be matched with the connector of another board, and the first press-fit cable connector and the second press-fit cable connector can be detached from the connector of another board, and the first press-fit cable connector and the second press-fit cable connector can each be different types of connectors, the flexibility of the board-level architecture during configuration can be increased. In addition, the other board connected to the backplane can be located on the same side of the backplane to facilitate a detachable connection between the service board and the fabric card.

[0013] In a particular feasible solution, the backplane comprises a stacked high-speed backplane and a power supply backplane, a first press-fit cable connector and a second press-fit cable connector are individually press-fitted onto a second surface of the high-speed backplane, a first pluggable connector and a second pluggable connector are individually press-fitted onto a first surface of the high-speed backplane, and a through hole for avoiding the first pluggable connector and the second pluggable connector is disposed in the power supply backplane.

[0018] In a specific feasible solution, there are a plurality of first press-fit cable connectors and a single second press-fit cable connector, and the plurality of first press-fit cable connectors are connected to the second press-fit cable connector via a cable, or there is a single first press-fit cable connector and a plurality of second press-fit cable connectors, and the first press-fit cable connector is connected to the plurality of second press-fit cable connectors via a cable. The first press-fit cable connector and the second press-fit cable connector may be arranged using different correspondence relationships.

[0019] According to a third aspect, a communication device is provided. The communication device includes a housing and a board-level architecture according to any one of the aforementioned feasible solutions disposed in the housing. A pluggable connector is configured to be electrically connected to a connector of another board. Thus, the pluggable connector and the connector of another board only need to be matched, and the first press-fit cable connector and the second press-fit cable connector can be separated from the connector of another board, and the first press-fit cable connector and the second press-fit cable connector can each be different types of connectors, thereby increasing the flexibility of the board-level architecture during configuration. Additionally, the second press-fit cable connector can be directly electrically connected to a switch board without the need to place a connector corresponding to the second press-fit cable connector, thereby simplifying the structure of the board-level architecture.

[0021] The following describes embodiments of the present application in detail with reference to the attached drawings.

[0022] To facilitate understanding of the board-level architecture provided in the embodiments of the present application, an application scenario of the board-level architecture is first described. The board-level architecture is applied to a communication system and implements the connection and communication of signals between different boards through connectors, for example, the method of connecting boards of a communication system in the prior art illustrated in FIG. 2. Board (1) is a fabric card, and board (2) is a circuit board. As the number of boards (2) increases, a larger connection space is required. Accordingly, a support board (4) is added above or below board (1), and the support board (4) is configured to support a connector assembly. As shown in FIG. 2, the connector assembly is fastened to the support board (4). The connector (6) and connector (7) of the connector assembly are fitted into the connector (5) of board (2) and the connector (8) of board (1), respectively, to implement signal exchange. As can be seen in FIG. 2, the connector (6) and connector (7) are redeveloped according to the characteristics of the connector (5) and connector (8), and their utility is very low. In addition, since both sides of the connector assembly must be additionally fitted into the connector to be joined, high-speed performance loss and high costs occur. Accordingly, embodiments of the present application provide a board-level architecture to simplify the connection of the board-level architecture and improve the applicability of the board-level architecture. The board-level architecture is described in detail below with reference to specific accompanying drawings and embodiments.

[0023] FIG. 3 is a schematic diagram of a specific application of a board-level architecture according to an embodiment of the present application. The board-level architecture may include a support board (30), a switch board (10), and a press-fit assembly (40). The press-fit assembly (40) is configured to extend a connection port of the switch board (10), and the support board (30) is configured to carry the press-fit assembly (40) as an extension of the switch board (10). When the board-level architecture is configured to be connected to a service board (20), a portion of the service board (20) is directly connected to the switch board (10) through a connector, and another portion of the service board (20) is connected to the press-fit assembly (40) and connected to the switch board (10) through the press-fit assembly (40).

[0024] FIG. 4 is a schematic diagram of a specific structure of a board-level architecture according to an embodiment of the present application. For some reference numerals in FIG. 4, the same reference numerals in FIG. 3 are referenced. A press-fit assembly (40) is primarily involved in the board-level architecture provided in this embodiment of the present application, and the press-fit assembly (40) is configured to extend a connection port of a switch board (10). The press-fit assembly (40) includes a first connector assembly (41), a second connector (42), and a cable (43) connecting the first connector assembly (41) and the second connector (42). The first connector assembly (41) is press-fitted into a side edge of a support board (30) and configured to be connected to a service board (20). The second connector (42) is press-fitted into a side edge of a switch board and configured to be electrically connected to the switch board (10).

[0025] The first connector assembly (41) is a coupling connector. The first connector assembly (41) includes a pluggable connector (412) and a first press-fit cable connector (411), and the pluggable connector (412) is electrically connected to the first press-fit cable connector (411). The first press-fit cable connector (411) is located within the coverage of the support board (30). The pluggable connector (412) is located further away from the support board (30) than the first press-fit cable connector (411), and some or all of it may be located outside the support board (30). One end of the pluggable connector (412) is configured to be connected to a connector of the service board (20), and the other end of the pluggable connector (412) is configured to be detachably connected to the first press-fit cable connector (411). The first press-fit cable connector (411) is connected to a cable (43). When the above-described structure is used, the first press-fit cable connector (411) does not directly match the connector of the service board (20). Therefore, when a different type of connector is used on the service board (20), only the pluggable connector (412) needs to be replaced without the need to replace the first press-fit cable connector (411) connected to the cable (43), or a pluggable connector (412) that matches the connector is used, thereby separating the first press-fit cable connector (411) from the connector of the service board (20), so that the applicability of the press-fit assembly (40) can be improved.

[0026] In an optional solution, the second connector (42) may also be a press-fit cable connector. For convenience of explanation, the press-fit cable connector is referred to as the second press-fit cable connector. When the press-fit assembly (40) is electrically connected to the switch board (10), the second press-fit cable connector may be directly connected to the switch board (10) through press-fitting and electrically connected to the circuit layer of the switch board (10). By comparing FIG. 3 and FIG. 5, compared to the method in the prior art where the press-fit assembly (40) is detachably connected to the switch board (10) through two connectors, according to the press-fit assembly (40) provided in this embodiment of the application, an additional connector is fitted and coupled to the second press-fit cable connector, thereby separating the second press-fit cable connector and reducing the number of connection points, which can improve the high-speed information transmission performance of the cable (43) and reduce the cost of the board-level architecture.

[0027] FIG. 5 illustrates the structure of a press-fit cable connector of a press-fit assembly. For some reference numerals in FIG. 5, the same reference numerals in FIG. 4 are referenced. The first press-fit cable connector (411) and the second press-fit cable connector (421) provided in this embodiment of the application are individually connected to both ends of the cable (43) based on a one-to-one correspondence. A pluggable connector (412) can be detachably connected to the first press-fit cable connector (411).

[0028] The first press-fit cable connector (411) has a plurality of first pins (4111). The pluggable connector (412) has a plurality of second pins (4121). The second pins (4121) and the first pins (4111) can be electrically connected through an adapter. The second press-fit cable connector (421) has a plurality of third pins (4211). When press-fitting is performed on a circuit board, the second press-fit cable connector (421) can be electrically connected to the circuit board.

[0029] In an optional solution, the first pin (4111), the second pin (4121), and the third pin (4211) are arranged in an array form. The aforementioned pins may be arranged in other ways.

[0030] In an optional solution, in addition to the one-to-one method illustrated in FIG. 5, the first press-fit cable connector (411) and the second press-fit cable connector (421) may use different methods, such as one-to-many or many-to-one methods. For example, there may be multiple first press-fit cable connectors (411) and one second press-fit cable connector (421), and multiple first press-fit cable connectors (411) may be connected to the second press-fit cable connector (421) via a cable, or there may be one first press-fit cable connector (411) and multiple second press-fit cable connectors (421), and the first press-fit cable connector (411) may be connected to multiple second press-fit cable connectors (421) via a cable. A flexible configuration method may be implemented using different correspondences to increase the flexibility of the board-level architecture during configuration.

[0031] FIG. 6 illustrates a specific structure of a switch board. Only the method of connection between the switch board (10) and other boards is specifically included in this application. The chip (11) and assembly specifically placed on the switch board (10) are not particularly limited. In the prior art, the assembly of a consistent functional board and the arrangement of the assembly in a communication system may be applied to this embodiment of the application. For example, the chip (11) is placed on the switch board (10), and the chip (11) is connected to the circuit layer of the switch board (10). A third connector (12) is placed on the edge of the switch board (10). The model of a plurality of third connectors (12) matches the model of the connector of the service board, and the connector of the service board can be directly and detachably connected to the third connector (12).

[0032] In an optional solution, if the second connector of the press-fit assembly is a press-fit cable connector, a press-fit area (13) corresponding to the second press-fit cable connector is placed on the switch board (10). A metallized via (not shown in FIG. 6) into which the third pin of the second press-fit cable connector is inserted is placed in the press-fit area (13). When the third pin is inserted into the metallized via, the second press-fit cable connector can be connected to a circuit layer of the switch board (10) through a connection between the third pin and the metallized via.

[0033] FIG. 7 is a schematic diagram of a specific structure of a support board. The support board (30) is configured to have a press-fit assembly, and the support board (30) has a first surface used to have the press-fit assembly, and the press-fit assembly can be fastened to the first surface. When having a press-fit assembly, a pluggable connector is press-fitted into the support board (30), and a first press-fit cable connector is also press-fitted into the support board (30). After being press-fitted into the structural part, the first press-fit cable connector is electrically connected to the pluggable connector.

[0034] In the present application, the specific structural form of the support board (30) is not limited. For example, the support board (30) may have various shapes such as a rectangle, a square, or an ellipse.

[0035] In an optional solution, the switch board may be positioned in parallel with the support board to facilitate the fastening of the press-fit assembly. In the specific example illustrated in FIG. 4, the switch board (10) and the support board (30) are located on the same plane. Alternatively, a specific height difference exists between the switch board (10) and the support board (30) to accommodate the installation space of the board-level architecture in the communication device.

[0036] Additionally, the support board (30) may be further configured to separate the connector of the press-fit assembly from the connector of the service board. An adapter (31) into which the press-fit assembly is fitted is placed on the support board (30). FIG. 8 is a schematic diagram of assembling the press-fit assembly to the adapter. A pluggable connector (412) can be press-fitted into the adapter (31) in direction a, and a first press-fit cable connector (411) can be press-fitted into the adapter (31) in direction b, and the first press-fit cable connector (411) can be electrically connected to the pluggable connector (412) through the adapter (31). Directions a and b are opposite directions.

[0037] In an optional implementation solution, when the press-fit assembly uses the structure illustrated in FIG. 5, a plurality of metallized vias are disposed on the adapter (31). A plurality of first pins of the first press-fit cable connector (411) can be inserted into corresponding metallized vias based on a one-to-one correspondence. A plurality of second pins of the pluggable connector (412) can be inserted into corresponding metallized vias based on a one-to-one correspondence. The pluggable connector (412) is electrically connected to the first press-fit cable connector (411) through the metallized vias.

[0038] In an optional implementation solution, the adapter (31) may be a PCB or other circuit board capable of implementing a conductive connection between two assemblies.

[0039] In an optional solution, the adapter (31) is fastened to a first surface of the support board (30). For example, the adapter (31) may be fastened to the first surface of the support board (30) through bonding, welding, or a threaded connection piece (bolt or screw).

[0040] In an optional solution, the adapter (31) may be part of the support board (30). For example, a method similar to placing a press-fit area on a switch board may be used to directly obtain metallized vias on the support board (30). The pluggable connector (412) and the first press-fit cable connector (411) are separately press-fitted into the metallized vias of the support board (30) from two surfaces on opposite sides of the support board (30) to implement an electrical connection between the pluggable connector (412) and the first press-fit cable connector (411).

[0041] FIG. 9 illustrates another board-level architecture according to an embodiment of the present application. For some reference numerals in FIG. 9, the same reference numerals in FIG. 3 are referenced. The difference from the board-level architecture illustrated in FIG. 3 is that the service board (20) in FIG. 3 is a connection assembly of the board-level architecture, whereas in the board-level architecture of FIG. 8, a part of the service board (20) is directly connected to the connector of the switch board (10) through a connector (21), and the connector of another service board (20) is connected to the first connector assembly (41) of the press-fit assembly (40) and connected to the switch board (10) through the press-fit assembly (40). When connected through the press-fit assembly (40), the connector (21) connected to the service board (20) can be detachably connected to the first connector assembly (41). When the above-described structure is used, only pluggable connectors are connected to the connector of the service board (20). Therefore, the pluggable connector and the connector of the service board (20) only need to be matched, and the first press-fit cable connector and the second press-fit cable connector can be separated from the connector of the service board (20). Thus, the first press-fit cable connector and the second press-fit cable connector can each be different types of connectors, thereby increasing the flexibility of the board-level architecture during configuration. Additionally, the second press-fit cable connector can be directly electrically connected to the switch board (10) without the need to place a connector corresponding to the second press-fit cable connector, so the structure of the board-level architecture can be simplified.

[0042] FIG. 10 is a schematic diagram of another board-level architecture application according to an embodiment of the present application. The board-level architecture provided in this embodiment of the present application may be applied to a backplane scenario of a communication system. The board-level architecture may include a backplane (100) and a press-fit assembly (300). When the board-level architecture is configured to connect a service board (200) and a switch board (400), the service board (200) and the switch board (400) may be connected via the press-fit assembly (300) using a signal, and the service board (200) and the switch board (400) are supported by the backplane (100).

[0043] Referring still to FIG. 10, the press-fit assembly (300) is primarily included in the board-level architecture provided in this embodiment of the application. The press-fit assembly (300) includes a first connector assembly (310), a second connector assembly (320), and a cable (330) connecting the first connector assembly (310) and the second connector assembly (320). The first connector assembly (310) and the second connector assembly (320) are configured to be connected to a service board (200) and a switch board (400).

[0044] In the present embodiment of the application, the first connector assembly (310) and the second connector assembly (320) are both coupling connectors, and the first connector assembly (310) includes a first pluggable connector (311) and a first press-fit cable connector (312), and the first pluggable connector (311) can be electrically connected to the first press-fit cable connector (312). One end of the first pluggable connector (311) is configured to be connected to the connector (201) of the service board (200), and the other end is configured to be connected to the first press-fit cable connector (312). The first press-fit cable connector (312) is connected to the cable (330).

[0045] The second connector assembly (320) includes a second pluggable connector (321) and a second press-fit cable connector (322), and the second pluggable connector (321) can be electrically connected to the second press-fit cable connector (322). One end of the second pluggable connector (321) is configured to be connected to a connector (401) of a switch board (400), and the other end is configured to be connected to the second press-fit cable connector (322). The second press-fit cable connector (322) is connected to a cable (330).

[0046] For the specific structure of the first press-fit cable connector (312) and the second press-fit cable connector (322), refer to the detailed description in FIG. 5. Further details are not described here.

[0047] When the press-fit assembly (300) is assembled to the backplane (100), the first pluggable connector (311) and the second pluggable connector (321) are individually press-fitted to the first surface of the backplane (100), the first press-fit cable connector (312) is press-fitted to the second surface of the backplane (100), the first press-fit cable connector (312) is electrically connected to the first pluggable connector (311), the second press-fit cable connector (322) is press-fitted to the second surface of the backplane (100), and the second press-fit cable connector (322) is electrically connected to the second pluggable connector (321). When electrical connections are specifically implemented, taking the first connector assembly (310) as an example, a plurality of metallized vias (not shown in FIG. 11) are disposed on the backplane (100), and each of the first press-fit cable connector (312) and the second cable connector (322) has a first pin that fits the plurality of metallized vias. The first pluggable connector (311) and the second pluggable connector (321) each have a second pin that fits the plurality of metallized vias. The first pluggable connector (311) is connected to the corresponding first press-fit cable connector (312) through a connection between the metallized vias and the first pin and the second pin.

[0048] In an optional example, a press-fit area for connecting the first connector assembly (310) and the second connector assembly (320) is placed on the backplane (100), and the aforementioned metallized via is placed within the press-fit area. The first pluggable connector (311) and the first press-fit cable connector (312) are pressed into the press-fit area on two opposite surfaces of the backplane (100) to establish an electrical connection. The assembly method of the second connector assembly (320) is the same as the assembly method of the first connector assembly (310), and a detailed description is not provided again.

[0049] In FIG. 10, the backplane (100) serves as both a circuit board and a support board for the press-fit assembly (300). When the service board (200) and the switch board (400) are assembled, the connector (201) of the service board (200) and the connector (401) of the switch board (400) can be directly connected to the first pluggable connector (311) or the second pluggable connector (321). Thus, the high-speed signal of the press-fit assembly (300) can be transmitted to the backplane (100), and the low-speed signal and power supply signal can be transmitted through other connectors of the backplane (100).

[0050] When the first connector assembly (310) and the second connector assembly (320) use a combined connector, the first press-fit cable connector (312) connected to the cable (330) does not need to be matched with the connector (201) of the service board (200), and the second press-fit cable connector (322) does not need to be matched with the connector (401) of the switch board (400). Accordingly, when the connector (201) and the connector (401) are different types of connectors, only the pluggable connector needs to be replaced without the need to replace the first press-fit cable connector (312) and the second press-fit cable connector (322) connected to the cable (330), or a pluggable connector that matches the connector (201) and the connector (401) is used, and the first press-fit cable connector (312) and the second press-fit cable connector (322) are separated from the connector (201) and the connector (401), thereby improving the applicability of the press-fit assembly (300).

[0051] In an optional solution, the first press-fit cable connector (312) and the second press-fit cable connector (322) may use different correspondences such as one-to-one, one-to-many, and many-to-one. For example, there may be multiple first press-fit cable connectors (312) and one second press-fit cable connector (322), and multiple first press-fit cable connectors (312) may be connected to the second press-fit cable connector (322) via a cable (330), or there may be one first press-fit cable connector (312) and multiple second press-fit cable connectors (322), and the first press-fit cable connector (312) may be connected to multiple second press-fit cable connectors (322) via a cable (330). The flexible configuration method may be implemented using different correspondences to increase the flexibility of the board-level architecture during configuration.

[0052] In an optional solution, the service board (200) and the switch board (400) may otherwise be used as part of a board-level architecture. The connector (201) of the service board (200) may be detachably connected to a first pluggable connector (311), and the connector (401) of the switch board (400) may be detachably connected to a second pluggable connector (321).

[0053] From the foregoing description, it can be seen that in the board-level architecture used in the present embodiment of the application, only the pluggable connector is electrically connected to the connector of another board. Therefore, the pluggable connector and the connector of another board only need to be matched, and the first press-fit cable connector (312) and the second press-fit cable connector (322) can be separated from the connector of another board. Thus, the first press-fit cable connector (312) and the second press-fit cable connector (322) can each be different types of connectors, thereby increasing the flexibility of the board-level architecture during configuration. Additionally, when the foregoing structure is used, the service board (200) and the switch board (400) can be placed on the same side of the backplane (100), thereby facilitating a detachable connection between the service board (200) and the switch board (400).

[0054] FIG. 11 illustrates a modified structure of the board-level architecture illustrated in FIG. 10. Unlike FIG. 10, the backplane (100) of FIG. 11 uses a multilayer structure. The backplane (100) includes a stacked power supply backplane (110) and a high-speed backplane (120). When in use, the high-speed backplane (120) is specifically configured to implement the transmission of a high-speed signal that transmits a high-speed signal of the press-fit assembly (300), and the power supply backplane (110) is specifically configured to implement the transmission of a low-speed signal and a power supply signal that transmits a low-speed signal and a power supply signal through another connector.

[0055] FIG. 12 is a schematic diagram of a high-speed backplane structure. Referring to FIG. 11 and FIG. 12, the high-speed backplane (120) has a first surface and a second surface located opposite each other, and a first press-fit cable connector (312) and a second press-fit cable connector (322) can be individually press-fitted onto the second surface of the high-speed backplane (120). A first pluggable connector (311) and a second pluggable connector (321) are individually press-fitted onto the first surface of the high-speed backplane (120).

[0056] In an optional solution, the adapter (130) is positioned on a high-speed backplane (120), and the first press-fit cable connector (312) and the first pluggable connector (311) are each press-fitted onto two surfaces opposite each other of the adapter (130). The second press-fit cable connector (322) and the second pluggable connector (321) are individually press-fitted onto two surfaces opposite each other of the adapter (130). In a specific connection, a plurality of metallized vias are positioned on the adapter (130), and the first pluggable connector (311) and the second pluggable connector (321) can be electrically connected to the first press-fit cable connector (312) and the second press-fit cable connector (322) through the metallized vias on the corresponding adapter (130).

[0057] In an optional implementation solution, the adapter (130) may be a PCB or other circuit board on which metallized vias can be placed. The adapter (130) may be attached to the high-speed backplane (120) by bonding, welding, etc., or the adapter (130) is part of the structure of the high-speed backplane (120).

[0058] FIG. 13 is a schematic diagram of a power supply backplane structure. A through hole (111) is provided on the power supply backplane (110) to avoid a first pluggable connector (311) and a second pluggable connector (321). When the power supply backplane (100) and the high-speed backplane (120) are stacked, the power supply backplane (110) and the high-speed backplane (120) may be connected by different connection methods, such as bonding, welding, or clamping, or may be connected via threaded connection pieces (bolts or screws). The power supply backplane (110) and the high-speed backplane (120) are in parallel, and the through hole (111) on the power supply backplane (110) corresponds one-to-one with the adapter (130) on the high-speed backplane (120), so that the adapter (130) can be exposed in the through hole (111). When the first pluggable connector (311) and the second pluggable connector (321) are assembled, the first pluggable connector (311) and the second pluggable connector (321) can be connected to the adapter (130) after passing through the through hole (111) on the power supply backplane (110).

[0059] In an optional solution, the first press-fit cable connector (312) and the second press-fit cable connector (322) may use different correspondence methods, such as a one-to-one method, a one-to-many method, and a many-to-one method. For example, there may be multiple first press-fit cable connectors (312) and one second press-fit cable connector (322), and multiple first press-fit cable connectors (312) may be connected to the second press-fit cable connector (322) via a cable (330), or there may be one first press-fit cable connector (312) and multiple second press-fit cable connectors (322), and the first press-fit cable connector (312) may be connected to multiple second press-fit cable connectors (322) via a cable (330). A flexible configuration method may be implemented using different correspondences to increase the flexibility of the board-level architecture during configuration.

[0060] In an optional solution, the service board (200) and the switch board (400) may otherwise be used as part of a board-level architecture. The connector (201) of the service board (200) may be detachably connected to a first pluggable connector (311), and the connector (401) of the switch board (400) may be detachably connected to a second pluggable connector (321).

[0061] From the foregoing description, it can be seen that in the board-level architecture used in the present embodiment of the application, only the pluggable connector is electrically connected to the connector of another board. Therefore, the pluggable connector and the connector of another board only need to be matched, and the first press-fit cable connector (312) and the second press-fit cable connector (322) can be separated from the connector of another board. Thus, the first press-fit cable connector (312) and the second press-fit cable connector (322) can each be different types of connectors, thereby increasing the flexibility of the board-level architecture during configuration. In addition, when the foregoing structure is used, the service board (200) and the switch board (400) are placed on the same side of the backplane (100) to facilitate the detachable connection of the service board (200) and the switch board (400).

[0062] Embodiments of the present application further provide a communication device. The communication device includes a housing and a board-level architecture according to any one of the aforementioned optional solutions disposed in the housing. A pluggable connector is configured to be electrically connected to a connector of another board. Thus, the pluggable connector and the connector of another board only need to be matched, and the first press-fit cable connector and the second press-fit cable connector can be separated from the connector of the other board. Thus, the first press-fit cable connector and the second press-fit cable connector may each be different types of connectors, thereby increasing the flexibility of the board-level architecture during configuration. Additionally, the second press-fit cable connector can be directly electrically connected to a service board without the need to place a connector corresponding to the second press-fit cable connector, thereby simplifying the structure of the board-level architecture.

[0063] It is apparent that those skilled in the art may make various modifications and changes to this application without departing from the spirit and scope of this application. This application is intended to include such modifications and changes to this application only if such modifications and changes fall within the scope of protection defined by the following claims and their equivalents.
