In order to make the connectors have better coplanarity, the structure for supporting the connectors is generally integrally formed by machining, but the number of the connectors is required to be larger to meet the requirements of high-speed, high-density, multi-channel and large-span signal interconnection, so that the structure for supporting the connectors has larger size. On the basis, in order to meet the requirements of coplanarity of a plurality of connectors, the supporting structure can be caused to face the difficulties of high processing difficulty, high processing precision requirement, low yield and the like. The embodiment of the present application provides a back plate, which aims to solve the above problems, and the following describes in detail the structure of the back plate provided by the present application with reference to the accompanying drawings.

Wherein, the housing 201 may be used to support a plurality of connector assemblies 202 to assemble the back plate 2 by fixing the plurality of connector assemblies 202 to the housing 201, thereby facilitating the installation of the back plate 2 with a cabinet or a plug frame, etc. Referring to fig. 3, one end of the connector 2021 of the connector assembly 202 may be connected to a cable (not shown) that may be connected to other connectors 2021 through the cavity of the housing 201 or may be connected to a switching node through the cavity of the housing 201; the other end of the connector 2021 has an interface to connect with the server nodes, thereby realizing signal interconnection between the server nodes. The switching node may be a switch, and the server node may be a computing node or a storage node.

When a plurality of connector assemblies 202 are arranged, referring to fig. 2, the plurality of connector assemblies 202 may be arranged side by side, so that the housing 201 may be arranged in a long form. It will be appreciated that in other embodiments, the arrangement of the connector assemblies 202 may be arranged according to the arrangement of the server nodes with which they are docked, and that the housing 201 may be arranged according to the arrangement of the connector assemblies 202. The plurality of connection assemblies 203 are used for fixedly connecting the plurality of connector assemblies 202 and the housing 201, wherein one end of each connection assembly 203 is fixedly connected with the housing 201, the other end of each connection assembly 203 is provided with an end face closely attached to the connector assembly 202, and the end faces of the plurality of connection assemblies 203 attached to the connector assembly 202 are arranged in a flush manner.

With the back plate 2 of the embodiment of the present application, since the end surfaces of the plurality of connection assemblies 203, which are tightly attached to the connector assemblies 202, are arranged in a coplanar manner, the end surfaces of the plurality of connector assemblies 202 can be arranged in a coplanar manner, so that when the types of the plurality of connectors 2021 are the same, the interfaces of the connectors 2021 of the plurality of connector assemblies 202 can be flush, thereby being beneficial to improving the connection reliability between the server nodes and the corresponding connectors 2021. In addition, the housing 201 of the back plate 2 does not need to ensure the flatness setting of the housing 201 while playing a supporting role on a plurality of connector assemblies 202, and has lower requirements on rigidity and processing precision of the housing 201, thereby being beneficial to reducing the control difficulty and processing cost of the processing technology and improving the product yield.

Referring to fig. 3 and 4, fig. 4 is an enlarged view of a partial structure at B in bitmap 3.

The shell 201 can be made of low-cost molding process materials such as sheet metal steel plates, sheet metal aluminum plates, profiles and the like with lower precision, so that the cost of the shell 201 is reduced while the requirement of supporting strength can be met.

In addition, with continued reference to fig. 3, in the embodiment shown in fig. 3, the plurality of connector assemblies 202 are disposed inside the cavity of the housing 201, and in order to connect the ports of the connectors 2021 of the connector assemblies 202 with the server nodes, the connectors 2021 need to be protruded out of the housing 201, so that a through hole (not shown in the drawing) needs to be formed in the housing 201 to expose the connectors 2021.

Since the end of the connector 2021 connected to the connector mount 2022 may be provided with a cable, the cable is accommodated in the cavity of the housing 201, so as to facilitate storage and arrangement of the cable and connection of the cable to the switching node. The connector assembly 203 may be coupled to the connector mount 2022 when the connector assembly 202 is fixedly coupled to the housing 201 by the connector assembly 203.

There are various fixing manners between the connector 2021 and the connector mount 2022, and the connector 2021 is fixed to the connector mount 2022 by bonding or welding; or the connector 2021 is integrally formed with the connector mount 2022; alternatively, the connector 2021 has a fixing edge 2024 (not shown in fig. 4, refer to fig. 6), and referring to fig. 5, the connector assembly 202 may further include a connector fixing piece 2023, so that the fixing edge 2024 may be pressed against the connector fixing base 2022 by the connector fixing piece 2023, and then the connector fixing piece 2023 may be locked to the connector fixing base 2022 by a fastener 2033 such as a bolt or a bayonet. In addition, each connector 2021 may be provided with one connector housing 2022, or several connectors 2021 may share one connector housing 2022, for example, as shown in fig. 5, two connectors 2021 may be fixed on one connector housing 2022.

In this embodiment, it can be understood that when the connector assembly 202 includes the connector holder 2022, the end face of the connector assembly 203 attached to the connector assembly 202 can be directly attached to the connector holder 2022, so that the end faces of the connector holders 2022 of the plurality of connector assemblies 202 can be arranged in a coplanar manner, and when the types of the connectors 2021 in the back plate 2 are the same, the end faces of the interfaces of the connectors 2021 for connection with the server nodes can be coplanar, so that reliable connection between the server nodes and the corresponding connectors 2021 can be realized.

In addition, in the embodiment of the present application, by disposing the connector mounts 2022 in the connector assemblies 202 and by disposing the end surfaces of the connector mounts 2022 of the respective connector assemblies 202 in a coplanar manner, the coplanar disposing operation of the plurality of connector assemblies 202 can be effectively simplified, which is beneficial to improving the assembly efficiency of the back plate 2.

In the specific arrangement of the connection assembly 203, the connection assembly 203 may be arranged in a variety of ways, referring to fig. 6, in the embodiment shown in fig. 6, the connection assembly 203 may include a connection stud 2031, and for fixedly connecting the housing 201 and the connector assembly 202 by using the connection stud 2031, a first threaded hole (not shown in the drawings) may be provided on an end surface of the housing 201, so that the connection stud 2031 may be connected to the housing 201 by screwing with the first threaded hole, and meanwhile, the end surface of the connection stud 2031 is attached to the connector assembly 202. For ease of understanding, in the following embodiments, the connector assembly 202 includes the connector 2021 and the connector mount 2022, and the connection assembly 203 is fixedly connected to the connector mount 2022, and a connection manner in which the housing 201 and the connector assembly 202 are connected by the connection assembly 203 will be described. Thus, in this embodiment, the end face of the connection stud 2031 can be bonded to the end face of the connector mount 2022, and the connector mount 2022 can be fixed to the connection stud 2031 by a fastener 2033 such as a screw.

It will be appreciated that in order to ensure that the end surfaces of the respective connector studs 2031 that are in contact with the connector housing 2022 are coplanar, a release design between the housing 201 and the connector assembly 202 is achieved, allowing a certain amount of deformation of the housing 201 during the locking of the first locking nut 2032, thereby achieving the purpose of locking the amount of deformation of the housing 201 so as to reduce the amount of deformation of the housing 201 during use.

In the case of providing the connection stud 2031 specifically, referring to fig. 6, when a hole provided opposite to the connection stud 2031 is provided in the server node connected to the connector 2021, the connection stud 2031 is inserted into the hole provided in the server node, thereby realizing the function of guiding the connection between the server node and the connector 2021.

In addition to the above structure, in the embodiment of the present application, referring to fig. 3, the back plate 2 may further include a cable cover 204, where the cable cover 204 is covered on the housing 201, so as to form a receiving cavity between the housing 201 and the cable cover 204, so that the cable of the connector 2021 for connecting to the switching node can be received in the receiving cavity, so as to achieve arrangement, storage and protection of the cable.

In order to further understand the structure, connection manner, and arrangement principle of the housing 201, the connector assembly 202, and the connection assembly 203 of the back plate 2 in the foregoing embodiments, the present embodiment further provides a processing method of the back plate 2, where a flowchart of the processing method may be shown in fig. 7, and the method may specifically include the following steps:

In this way, before the connector assembly 202 is placed on the plurality of connection studs 2031, the deformation amount of the housing 201 can be locked by locking the locking nut, so as to avoid the housing 201 from being deformed during the use of the back plate 2 in the embodiment of the application, so as to improve the supporting reliability of the housing 201 to the connector assembly 202. In addition, since the deformation of the housing 201 is locked, the end surfaces of the plurality of connection studs 2031 are always abutted against the coplanarity tool table surface 3, so that the coplanarity precision of the end surfaces of the plurality of connection studs 2031 can be effectively improved, thereby being beneficial to improving the coplanarity precision of the end surfaces of the interfaces of the plurality of connectors 2021 connected with the server nodes.
