The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0036] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0037] like Figure 1 and Figure 2 As shown, the motherboard power supply device of the embodiment of the present application includes a chassis 100, a first circuit board 200 and a power supply module 300. The first circuit board 200 is installed in the chassis 100 and has a first electrical connector 210 for connecting to a first power supply module (not shown in the figure). The power supply module 300 is detachably connected to the chassis 100; the power supply module 300 includes a second electrical connector 311 (as shown in the figure). Figure 5 ) of the second circuit board 310, the second circuit board 310 is detachably electrically connected to the first circuit board 200, and the second electrical connector 311 is used to connect to a second power supply module (not shown in the figure).

[0038] In an embodiment of the present application, when the mainboard power supply device needs to be configured with two power modules (i.e., a first power module and a second power module), the second circuit board 310 is electrically connected to the first circuit board 200, and the first power module and the second power module are respectively connected to the first electrical connector 210 and the second electrical connector 311, so that the first power module and the second power module can supply power to the first circuit board 200 through the second circuit board 310; when the mainboard power supply device needs to be configured with one power module, the second circuit board 310 and the second power module are removed from the mainboard power supply device, and the first power module is connected to the first electrical connector 210 of the first circuit board 200, so that the first power module directly supplies power to the first circuit board 200.

[0039] It can be seen that in the mainboard power supply device of the embodiment of the present application, the first circuit board 200 has a first electrical connector 210 for connecting to the first power module, the second circuit board 310 has a second electrical connector 311 for connecting to the second power module, and the second circuit board 310 is detachably electrically connected to the first circuit board 200, so that the mainboard power supply device can adapt to different power supply modes, such as configuring two power modules or one power module, and selectively installing or removing the second circuit board 310 according to different power supply modes. When the second circuit board 310 is removed, it saves costs and avoids affecting the heat dissipation efficiency of the power module due to the second circuit board 310 blocking the heat dissipation air duct of the power module.

[0040] like Figure 1 As shown, the chassis 100 may include a bottom plate 120 and a side plate 130, the side plate 130 is connected to the edge of the bottom plate 120, and the bottom plate 120 and the side plate 130 together enclose a mounting cavity 140. The first circuit board 200 is located in the mounting cavity 140 and laid flat on the bottom plate 120.

[0041] In one embodiment, the second circuit board 310 and the first circuit board 200 may be vertically arranged, but the present invention is not limited thereto.

[0042] like Figure 3 As shown, the chassis 100 further includes a power supply frame 110, which is disposed in the mounting cavity 140. In one embodiment, the power supply frame 110 is disposed at the connection between the bottom plate 120 and the side plate 130.

[0043] The power frame 110 encloses a receiving cavity 111 for receiving the first power module and the second power module. One end of the power frame 110 along the length direction of the power frame 110 has an opening 112 connected to the receiving cavity 111; the power supply module 300 is detachably connected to the power frame 110 and covers the opening 112.

[0044] In the embodiment of the present application, when the mainboard power supply device needs to be equipped with two power modules, the power supply module 300 is installed at the opening 112 of the power frame 110; when the mainboard power supply device needs to be equipped with one power module, the power supply module 300 is removed from the power frame 110, and the first power module is directly electrically connected to the first electrical connector 210 of the first circuit board 200. At this time, since the power supply module 300 has been removed from the opening 112 of the power frame 110, there is no situation of blocking the opening 112 of the power frame 110, thereby improving the heat dissipation efficiency of the power module.

[0045] like Figure 3 As shown, the first circuit board 200 is located on the side of the power frame 110 where the opening 112 is located, and at least a portion of the first electrical connector 210 extends into the accommodating cavity 111 through the opening 112 .

[0046] In the embodiment of the present application, at least a portion of the first electrical connector 210 of the first circuit board 200 extends into the accommodating cavity 111 through the opening 112 of the power frame 110 , so that the first power module and the first electrical connector 210 are more convenient to plug into each other.

[0047] like Figure 4 and Figure 5 As shown, the power supply module 300 further includes an adapter 320, which is detachably connected to the power frame 110 and covers the opening 112, and the second circuit board 310 is mounted on the side of the adapter 320 that faces away from the accommodating cavity 111. The second circuit board 310 is mounted on the power frame 110 through the adapter 320, which can avoid accidental damage to the second circuit board 310 during the installation process due to the direct connection of the second circuit board 310 with the power frame 110.

[0048] like Figure 5 As shown, the adapter 320 has a window 321, and the window 321 penetrates the adapter 320 along the length direction of the power frame 110; the second electrical connector 311 is arranged in the window 321 and extends into the accommodating cavity 111. On the one hand, the second electrical connector 311 of the second circuit board 310 is arranged in the window 321 of the adapter 320, so that the structure after the adapter 320 and the second circuit board 310 are assembled is more compact, avoiding excessive occupation of space in the chassis 100; on the other hand, the second electrical connector 311 extends into the accommodating cavity 111 of the power frame 110, which facilitates the plugging of the second power module with the second electrical connector 311.

[0049] like Figure 4 and Figure 5 As shown, the adapter 320 includes a body 322 and a lap portion 323, the body 322 is located on the side where the opening 112 of the power frame 110 is located, and covers the opening 112 of the power frame 110, and the second circuit board 310 is stacked on the side surface of the body 322 facing away from the accommodating cavity 111. The lap portion 323 is connected to the body 322, and overlaps the top wall 114 of the power frame 110, and is detachably connected to the top wall 114 of the power frame 110.

[0050] In the embodiment of the present application, the adapter 320 is suspended on the top wall 114 of the power frame 110 through the overlapping portion 323, so that the staff can install it on the side where the top wall 114 of the power frame 110 is located. The space on the side where the top wall 114 of the power frame 110 is located is large enough, and the installation tools will not interfere with other components in the mainboard power supply device, thereby avoiding damage to other components due to accidental contact.

[0051] In one embodiment, the second circuit board 310 and the body 322 may be connected by bolt connection, clamping connection, gluing connection, etc. The lap portion 323 and the top wall 114 of the power frame 110 may be connected by bolt connection, clamping connection, gluing connection, etc.

[0052] like Figure 1 , Figure 3 and Figure 4 As shown, the adapter 320 further includes a side ear 324 . The side ear 324 is connected to the body 322 , covers the outer surface of the side wall 115 of the power frame 110 , and is detachably connected to the power frame 110 .

[0053] In one embodiment, the side ear 324 has a slot 3241 , and the outer surface of the side wall 115 of the power frame 110 is provided with a latching post 113 for latching into the slot 3241 .

[0054] The side ears 324 are covered on the outer surface of the side wall 115 of the power frame 110. Since other components may be present on the side where the outer surface of the side wall 115 of the power frame 110 is located, it is not convenient for operators to use tools to install the side wall 115 of the power frame 110. In the embodiment of the present application, the side ears 324 and the power frame 110 are installed by inserting the clamping column 113 into the clamping groove 3241. The installation process does not require the operator to operate tools, which not only ensures the firmness of the adapter 320 and the power frame 110 after assembly, but also improves the convenience of the assembly process.

[0055] like Figure 1 and Figure 4 As shown, the card slot 3241 includes a first slot 3241a and a second slot 3241b, the opening 112 of the first slot 3241a is directed away from the second circuit board 310, the second slot 3241b is connected to the first slot 3241a, and the opening 112 of the second slot 3241b is directed toward the first circuit board 200; wherein, the card column 113 passes through the first slot 3241a and is inserted into the second slot 3241b.

[0056] The first slot 3241a extends along the length direction of the power frame 110, and the second slot 3241b extends along the thickness direction of the first circuit board 200. In other words, the slot 3241 formed by the first slot 3241a and the second slot 3241b is substantially L-shaped.

[0057] In the embodiment of the present application, the adapter 320 is first moved along the length direction of the power frame 110 and in a direction close to the power frame 110, so that the clamping column 113 is clamped into the first groove 3241a. After the clamping column 113 is clamped into the end of the first groove 3241a, the adapter 320 is then moved in a direction close to the first circuit board 200, so that the clamping column 113 is clamped into the second groove 3241b, until the clamping column 113 moves to the end of the second groove 3241b. Since the clamping column 113 is finally clamped into the second groove 3241b, the adapter 320 and the power frame 110 form a limit in the length direction of the power frame 110, ensuring the stability of the adapter 320 and the second circuit board 310.

[0058] As an example, the width of the first groove 3241 a is greater than the width of the second groove 3241 b .

[0059] In the embodiment of the present application, the width of the first groove 3241a is relatively large, and the clamping column 113 is more easily aligned with the first groove 3241a, so that the clamping column 113 is quickly clamped into the first groove 3241a. When the clamping column 113 is clamped into the second groove 3241b from the first groove 3241a, the groove wall of the second groove 3241b cooperates with the clamping column 113 to limit the position. At this time, the width of the second groove 3241b is relatively small, which is more conducive to improving the stability of the limit.

[0060] like Figure 2 , Figure 4 and Figure 5 As shown, the first circuit board 200 has a first conductive terminal 220 , the second circuit board 310 has a second conductive terminal 312 , and the first conductive terminal 220 and the second conductive terminal 312 are connected via a conductive member 330 .

[0061] For example, the first circuit board 200 has two first conductive terminals 220, one of which is used as a positive terminal, and the other first conductive terminal 220 is used as a negative terminal. The second circuit board 310 has two second conductive terminals 312, one of which is used as a positive terminal, and the other second conductive terminal 312 is used as a negative terminal. The two second conductive terminals 312 are respectively connected to the two first conductive terminals 220 through two conductive members 330, so that the second circuit board 310 is electrically connected to the first circuit board 200.

[0062] In one embodiment, the first conductive terminal 220 and the second conductive terminal 312 may be copper seats, but the present invention is not limited thereto.

[0063] Of course, in other embodiments, the first circuit board 200 and the second circuit board 310 may also be electrically connected via a cable.

[0064] In one embodiment, the mainboard power supply device may be a server, wherein the first circuit board 200 is a mainboard, and the second circuit board 310 is a mainboard power supply backplane.

[0065] In summary, the mainboard power supply device of the embodiment of the present application has at least the following advantages and beneficial effects:

[0066] In the mainboard power supply device of the embodiment of the present application, the first circuit board 200 has a first electrical connector 210 for connecting to the first power module, the second circuit board 310 has a second electrical connector 311 for connecting to the second power module, and the second circuit board 310 is detachably electrically connected to the first circuit board 200, so that the mainboard power supply device can adapt to different power supply modes, such as configuring two power modules or one power module, and selectively installing or removing the second circuit board 310 according to different power supply modes. When the second circuit board 310 is removed, it saves costs and avoids affecting the heat dissipation efficiency of the power module due to the second circuit board 310 blocking the heat dissipation air duct of the power module.
