In the embodiment of the application, one side of the tail plate 130 facing the panel 120 is provided with the tail support parts 131 corresponding to the first connecting pieces 410 one by one, the tail support parts 131 are used for supporting one end of the board card facing away from the panel 120, the panel 120 is provided with the card pressing structure, the card pressing structure is arranged at one end of the panel 120 facing away from the carrier plate 110 along the thickness direction of the carrier plate 110, the card pressing structure is used for pressing and fixing the handle bars of the board card, and the board card can be firmly installed on the board card bracket 100 through the tail support parts 131 and the card pressing structure.

In some possible embodiments, the first connecting member 410 is a support column protruding from the first side in the thickness direction of the carrier plate 110, and an end surface of the first connecting member 410 facing away from the first side has a threaded hole 420. An end surface of the first connecting member 410 facing away from the first side surface is adapted to abut against the connector assembly 200, and a hole wall of the threaded hole 420 is adapted to be screwed with a fastener penetrating into the connection hole 240 of the connector assembly 200.

Illustratively, the connection plate 210 is provided with a hooking hole.

Illustratively, the carrier plate 110 is an upstanding plate.

In some examples, all of the first connectors 410 are distributed in a straight line along the second direction.

Thus, the size of the board card module is reduced, and the space occupied by the board card module is smaller.

When the second connection structure 500 includes a plurality of second connection members 510, all the second connection members 510 are linearly distributed along the second direction.

Thus, the size of the board card module is reduced, and the space occupied by the board card module is smaller.

As shown in fig. 1 to 4, when the connector assembly 200a includes the connection plate 210a to which the plurality of front connectors 220a are mounted, for example, when the connector assembly 200a is an expansion plate, the second connection structure 500 includes two second connection pieces 510 spaced apart in the second direction. The plurality of first connectors 410 includes a head-end first connector 411 and a tail-end first connector 412 respectively located at both ends of the first connection structure 400 in the second direction. The first connection 411 and one of the second connection 510 are arranged side by side along the first direction, and the first connection 412 and the other second connection 510 are arranged side by side along the first direction. The first head-end connector 411 and the first tail-end connector 412 are matched with the two second connectors 510, so that the connecting plate 210a is fixedly connected with the carrier 110.

In this way, the connection board 210a mounted with the plurality of front connectors 220a is facilitated to be fixedly connected with the carrier board 110. In addition, the head first connecting piece 411, the tail first connecting piece 412 and the two second connecting pieces 510 which are distributed in four corners can also make the connecting plate 210a and the carrier 110 more stable after being connected.

The first connection structure 400 includes 4 first connectors 410, and the first connectors 410 located between the head first connector 411 and the tail first connector 412 in the second direction may be used to fixedly connect the connection plates 210 of the other connector assemblies 200 with the carrier plate 110 after the connector assemblies 200a are replaced.

For example, two second connecting members 510 for fixedly connecting the connecting plate 210a with the carrier plate 110 are disposed on the first side surface of the carrier plate 110, that is, the second connecting members 510 may not be disposed on the second side surface of the fixing member 300a, and the connecting plate 210a is fixedly connected with the carrier plate 110 through 2 second connecting members 510, the first connecting member 411 at the head end and the first connecting member 412 at the tail end disposed on the first side surface of the carrier plate 110, so that the strength of the fixing member 300a is higher.
