Communication plugboard and communication device

Abstract

The invention, which belongs to the communication technology field, discloses a communication plugboard and a communication device, so that whether a connector is plugged firmly can be detected accurately and thus a transmission quality and stability of a high-speed signal are ensured. The communication plugboard comprises a plugboard connector and a firm plugging detection apparatus. Specifically, the plugboard connector being plugged with an opposite connector includes a plugboard signal pin and a plugboard detection pin; a sum of the length of the plugboard detection pin and a length of an opposite detection pin of the opposite connector is less than a sum of the length of the plugboard signal pin and a length of an opposite signal pin of the opposite connector. And the firm plugging detection apparatus that is connected with the plugboard detection pin is used for detecting whether the plugboard detection pin is contacted with the opposite detection pin.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication board and communication equipment. Background technique [0002] Existing communication equipment is usually designed in a modular manner. For example, a blade server contains multiple service modules. Each service module is implemented in the form of a single board. Multiple single boards can be Boards are connected to enable business communication. Such as figure 1 As shown, the single board 1 is connected to the backplane 2 in a pluggable manner, and service communication between multiple service modules is realized through the backplane. With the improvement of the I / O bandwidth of server equipment, the high-speed signal rate of the interconnection between boards is also increasing exponentially. To ensure the normal transmission of these high-speed signals, the connection status of the connector between the board and the backplane is required. It's g...

Problems solved by technology

The complete insertion of single-board connector 3 and backplane connector 4 requires that the pins of the two connectors coincide with a certain distance. If the two connectors are not inserted securely, the transmission quality and stability of high-speed signals will be reduced, and even cause the server unable to work properly

[0003] Existing servers judge whether the board is securely inserted by setting a micro switch on the board to detect the relative position between the board and the subrack. However, due to the processing tolerance between the board connector and the board, micro There are processing tolerances between the micro switch and the single board, and there are also processing tolerances between the single board connector and the backplane connector. These tolerances may add up to several millimeters or more, so the micro switch cannot accurately detect the two connections. Whether the device is inserted firmly
