Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2021/096500, filed on May 27, 2021, which claims priority to Chinese Patent Application No. 202010480697.2, filed on May 30, 2020. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD This disclosure relates to the field of communications technologies, and in particular, to a board-level architecture and a communications device. BACKGROUND In a communications system, different boards implement connections and communication of signals through connectors. In a current common communications system, vertical orthogonality is a common orthogonal architecture form. To implement insertion, removal, and replacement of a board, a large quantity of connectors is used in the system. FIG. 1 is a schematic diagram of a simple communications system. When a board 1 communicates with a board 2, both a connector 1 and a connector 2 are directly press-fitted on different boards, and then fit each other to implement transmission of a signal channel. In this system, as a quantity of boards 2 increases, a size of the board 1 becomes increasingly larger. Consequently, it is more difficult to process the board 1. In addition, as a signal transmission rate increases, electrical signal loss caused by a larger size of the board 1 also increases. To resolve the problem of the increase in the electrical signal loss, two solutions are mainly used currently. One method is to add a signal amplifier on the board 1, but implementation of the board 1 is complex and costs are high. The other method is to use a wire/cable with superior signal transmission quality, and this method also represents a trend for future development. However, when the wire/cable is used to transmit a signal, an inter-board connector is added. When different types of connectors are disposed on the board 2, implementing an inter-board connection becomes troublesome. SUMMARY This disclosure provides a board-level architecture and a communications device, to simplify a connection of the board-level architecture and increase flexibility of the board-level architecture during construction. According to a first aspect, a board-level architecture is provided, where the board-level architecture includes a support board, a switch board, and a press fit component, and the press fit component is configured to implement an electrical connection between components. The press fit component includes a cable, a first connector component press-fitted on a side edge of the support board, and a second press fit cable connector press-fitted on a side edge of the switch board. The first connector component includes a first press fit cable connector and a pluggable connector that is electrically connected to the first press fit cable connector, and the pluggable connector is farther 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 through the cable. When in use, the pluggable connector is configured to electrically connect to a connector of another board, to implement a communication connection between the switch board and the another board. Therefore, it is only required that the pluggable connector and the connector of the another board match, the first press fit cable connector and the second press fit cable connector may be decoupled from the connector of the another board, and the first press fit cable connector and the second press fit cable connector each may be another type of connector, so that flexibility of the board-level architecture during construction is increased. In addition, the second press fit cable connector may be directly electrically connected to the switch board without a need of disposing a connector corresponding to the second press fit cable connector, so that a structure of the board-level architecture is simplified. In a specific feasible solution, an adapter component is disposed on the support board, and the first press fit cable connector and the pluggable connector are respectively press-fitted on two opposite surfaces of the adapter component. A connection between the pluggable connector and the first press fit cable connector is facilitated. In a specific feasible solution, a plurality of metalized vias is disposed on the adapter component; the first press fit cable connector has first pins that fit the plurality of metalized vias; and the pluggable connector has second pins that fit the plurality of metalized vias. The pluggable connector is electrically connected to the first press fit cable connector through the metalized vias. In a specific feasible solution, the board-level architecture further includes a service board. The service board has a connector, and the connector of the service board may be detachably connected to the pluggable connector. The service boa
