FIG. 6A shows a schematic perspective view of an expansion plate in some embodiments; FIG. 6B shows a schematic diagram of an expansion board in some embodiments; figure 6C illustrates a schematic diagram of another expansion board in some embodiments. As shown in fig. 6A to 6C, the expansion board RS may include a board body RSB, and the board body RSB may be a circuit board structure.

In some examples, the expansion board RS may further include a third connector CON3 and a first expansion slot (not shown) on the board body RSB. The first expansion slot is coupled to the third connector CON3, and the third connector CON3 is coupled to the first connector CON1, and the first expansion slot may be coupled to the I/O card 300 by plugging. In this way, the signal board SB may extend the I/O card 300 on the first expansion slot through the first connector CON1 and the third connector CON3.

The second expansion slot is coupled to the fourth connector CON4, and the fourth connector CON4 is coupled to the second connector CON2, and the second expansion slot may be connected to the I/O card 300 by plugging. In this way, the signal board SB may extend the I/O card 300 on the second expansion slot through the second connector CON2 and the fourth connector CON4.

The fourth connector CON4 may be located between the signal board SB and the second expansion slot. The number of the second expansion slots may be greater than the number of the fourth connectors CON4, which is not limited herein.

It should be noted that, one expansion board RS may include both the third connector CON3 and the fourth connector CON4; it is also possible to include the third connector CON3 and not the fourth connector CON4, or to include the fourth connector CON4 and not the third connector CON3.

In some examples, the extension board RS includes both the third connector CON3 and the fourth connector CON4. As shown in fig. 6A and 6B, the board body RSB includes the second circuit board PCB2. The third connector CON3 and the fourth connector CON4 are both located on the second circuit board PCB2. In this example, the second circuit board PCB2 can expand the plurality of I/O cards 300 through the third connector CON3 and the fourth connector CON4, and the second circuit board PCB2 can complete the expansion of the plurality of I/O cards 300 only by performing one installation operation with the signal board SB, thereby reducing the installation steps of the server and improving the installation efficiency of the server. In addition, the specific corresponding connectors of the plurality of I/O cards 300 on the second circuit board PCB2 may also be selected according to practical situations in this example.

In other examples, the expansion board RS also includes both the third connector CON3 and the fourth connector CON4. As shown in fig. 6C, the board body RSB includes a third circuit board PCB3 and a fourth circuit board PCB4 that are independent of each other. The third connector CON3 is located on the third circuit board PCB3 and the fourth connector CON4 is located on the fourth circuit board PCB4. In this example, since the third circuit board PCB3 and the fourth circuit board PCB4 are independent from each other and the respective circuit boards have small volumes, the I/O module can flexibly adjust the positions and the numbers of the third circuit board and the fourth circuit board according to the product space, thereby improving the flexibility of the expansion of the I/O card.

In a case where the extension board RS includes both the third connector CON3 and the fourth connector CON4, the third connector CON3 and the fourth connector CON4 may be respectively located at both sides of the first circuit board PCB1 in the third direction Z. On this basis, the first expansion slot and the second expansion slot may be respectively located on both sides of the first circuit board PCB1 in the third direction Z.

In the embodiment of this application, set up first connector CON1 and second connector CON2 through the both sides at signal plate SB, can increase the quantity of connector on the signal plate SB, and then be convenient for the server to increase the quantity and the kind of the I/O card 300 of extension to the external interface that the server utilized the I/O card improves the ability of coping with the business scene. Therefore, the server provided by the application can improve the capability of coping with the service scene by increasing the number and the types of the expanded I/O cards.

In some other schemes, to increase the number of I/O cards expanded in the server, the number of signal boards must be increased. The signal board is usually a main board, and increasing the number of the main boards greatly increases the cost of the server. The embodiment of the application can overcome the problem that the cost of the server is increased by expanding the number of the I/O cards.

In some embodiments, as shown in fig. 3, in the case where the number of the above-mentioned extension boards RS in the server 100 is plural, the plural extension boards RS are arranged at intervals from each other in the second direction Y. The spacing distance between two adjacent expansion boards RS is larger than the size of the I/O card 300 in the second direction Y so as to accommodate the I/O card 300 in the server 100.

In some examples, each extension board RS may extend the signal board SB by a plurality of I/O cards 300, and by providing a plurality of extension boards RS in the server, the number of I/O cards 300 extended by the signal board SB can be increased, so that the server can cope with more service scenarios.

It is to be understood that, as shown in fig. 6B, in the case where the extension board RS includes the second circuit boards PCB2, the plurality of second circuit boards PCB2 are arranged at intervals from each other in the second direction Y, and each of the second circuit boards PCB2 extends the plurality of I/O cards 300 through the third connector CON3 and the fourth connector CON4, respectively. As shown in fig. 6C, in the case where the extension board RS includes both the third circuit board PCB3 and the fourth circuit board PCB4, the server is provided with a plurality of third circuit boards PCB3 arranged at intervals from each other in the second direction Y on one side of the signal board SB, and a plurality of fourth circuit boards PCB4 arranged at intervals from each other in the second direction Y on the other side of the signal board SB. Each third circuit board PCB3 extends the plurality of I/O cards 300 through the third connector CON3, and each fourth circuit board PCB4 extends the plurality of I/O cards 300 through the fourth connector CON4.

In some examples, the plate body RSB is disposed perpendicular to the signal plate SB. It is understood that the board body RSB is disposed perpendicular to the first circuit board PCB1 of the signal board SB. In this way, the board RSB can occupy a smaller space in the second direction Y, which is convenient for the signal board SB to expand more expansion boards RS, thereby expanding more I/O cards 300, so that the server can deal with more service scenarios.

In some embodiments, the first expansion slot and/or the second expansion slot on the board body RSB are disposed parallel to the first direction X, and the I/O card 300 inserted into the first expansion slot and/or the second expansion slot is disposed substantially parallel to the first circuit board PCB1 of the signal board SB. The plurality of I/O cards 300 are arranged in a stacked arrangement with a space therebetween in the third direction Z.

The I/O card 300 is disposed substantially parallel to the first circuit board PCB1 of the signal board SB, so that the I/O card 300 can occupy a smaller space in the third direction Z, and it is convenient for one board RSB to expand more I/O cards 300, and thus it is convenient for the signal board SB in the server to expand more I/O cards 300, so that the server can cope with more service scenarios.

The number of the first expansion slots may be equal to the number of the second expansion slots, or the number of the first expansion slots may not be equal to the number of the second expansion slots, which is not limited herein.

For example, as shown in fig. 4B, in the first direction X, the second connector is located on a side of the first connector away from the extension board RS. In this case, the first connector CON1 is coupled with a third connector CON3 on a third circuit board PCB 3; the fourth circuit board PCB4 needs to extend further in the first direction X to an orientation close to the signal board SB with respect to the third circuit board PCB3 so that the second connector CON2 is coupled with the fourth connector CON4 on the fourth circuit board PCB4. Thus, as shown in fig. 6C, the size of the fourth circuit board PCB4 in the first direction X may be larger than the size of the third circuit board PCB3 in the first direction X.

Also for example, the second connector is located on a side of the first connector close to the third circuit board PCB3 in the first direction X. In this case, the second connector CON2 is coupled with a fourth connector CON4 on a fourth circuit board PCB 4; the third circuit board PCB3 needs to extend further in the first direction X to an orientation close to the signal board SB with respect to the fourth circuit board PCB4 so that the first connector CON1 is coupled with the third connector CON3 on the third circuit board PCB 3. Thus, the dimension of the third circuit board PCB3 in the first direction X may be larger than the dimension of the fourth circuit board PCB4 in the first direction X.

The dimensions of the third circuit board PCB3 and the fourth circuit board PCB4 in the first direction are adaptively adjusted by the relative positions of the first connector and the second connector, facilitating the coupling between the first connector and the third connector, and the coupling between the second connector and the fourth connector.

In some embodiments, the first connector CON1 and the second connector CON2 may be PCIE-enabled high-speed connectors. In this way, the signal board SB can perform high-speed signal transmission between the first connector CON1 and the second connector CON2 and the extended multiple I/O cards 300, so as to improve the interactive performance between the server and the extended devices, and facilitate the server to deal with more service scenarios more quickly.
