The invention relates to the technical field of servers, in particular to a cross-module board card signal interconnection device. The invention also relates to a server.

Background

With the development of the electronic technology in China, more and more electronic devices have been widely used.

Servers are important components in electronic devices, and are devices that provide computing services. Since the server needs to respond to and process the service request, the server has the capability of assuming and securing the service. The server is divided into a file server, a database server, an application program server, a WEB server and the like according to different service types provided by the server. The server mainly comprises a CPU, a memory module, a storage module, a heat dissipation module, a power module and other modules.

In a conventional server structure, if cross-module signal interconnection needs to be implemented between two modules in different installation positions or environments in a chassis, a high-density connector is generally used for butt joint interconnection. However, the application of the high-density connector has strict requirements on the relative height of the board card planes in the two modules with signal interaction, that is, because the two high-density connectors for realizing butt joint are respectively installed on the respective corresponding board card planes, the board card surfaces in the two modules with signal interconnection are required to be completely flush.

However, in the prior art, due to the influence of environmental factors such as structural limitation, installation space, board height limitation, and the like, the board surface heights of the two signal interconnected modules cannot be leveled, and thus normal docking of the two high-density connectors cannot be realized, and cross-module signal interconnection of the server is difficult to realize. According to part of technical schemes, the adapter is additionally arranged to realize butt joint of two uneven high-density connectors, but due to the wiring structural characteristics of the high-density connectors, the in-board signal wiring is long, the signal line loss is large, the loss of a common one-level high-density connector is about 3DB, and the problem of signal loss is further increased due to multi-level signal switching of the high-density connectors and the adapter.

Therefore, how to break through the limitation that the board card height of signal interconnection must be flush on the basis of realizing the signal interconnection of the server cross-module board cards, and reduce the signal interconnection switching level and the link loss at the same time is a technical problem faced by the technical personnel in the field.
