Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to a power supply and computing device. Background Technology

[0002] With the rise of big data, cloud computing, and AI (Artificial Intelligence), the computing power requirements of data center servers are increasing. The power consumption of CPUs (Central Processing Units) and related components is gradually increasing, requiring server power supplies to rise from a few hundred watts to over a thousand watts to meet the power requirements of CPUs and other power devices. However, this increased power consumption has led to poorer heat dissipation in server power supplies. Summary of the Invention

[0003] The purpose of this application is to provide a power supply and computing device for improving the heat dissipation effect of the power supply.

[0004] To achieve the above objectives, embodiments of this application provide the following technical solutions:

[0005] On one hand, a power supply is provided. The power supply includes a first circuit board, an expansion board, and multiple functional devices. The first circuit board includes a main body and a first connector located at one end of the main body, the first connector being electrically connected to an external second circuit board; the expansion board is disposed on the main body and electrically connected to the main body; wherein the projection of the expansion board on the first circuit board at least partially covers the first connector. The multiple functional devices include a first functional device and a second functional device; wherein the first functional device is disposed on the main body and electrically connected to the main body; the second functional device is disposed on the expansion board and electrically connected to the expansion board.

[0006] In the aforementioned power supply, multiple functional components include first functional components and second functional components. Multiple first functional components are mounted on a first circuit board, and multiple second functional components are mounted on an expansion board. By mounting an expansion board, some functional components, such as the second functional components, are placed on the expansion board, thereby increasing the circuit layout space on the first circuit board and improving the power supply's heat dissipation. Furthermore, the increased circuit layout space on the first circuit board reduces the difficulty of arranging the functional components within the power supply. Additionally, the projection of the expansion board onto the first circuit board at least covers a portion of the first connector. In existing technologies, the space above the first connector is unused and idle. The aforementioned power supply can utilize the space above the first connector to mount the expansion board, thereby increasing the usable space within the power supply, increasing its volume, reducing power density, and improving heat dissipation. Furthermore, the increased usable space within the power supply reduces the difficulty of arranging the functional components within the power supply. Moreover, utilizing the space above the first connector to mount the expansion board increases the power supply's volume without increasing the space occupied by the power supply on the bottom plate of the enclosure. In power supplies, power density can be understood as the ratio of the power of the power supply to its volume.

[0007] In some embodiments, the expansion board includes a first plate portion and a second plate portion, the first plate portion and the second plate portion being electrically connected; wherein the first plate portion is disposed opposite to the first plug portion; and the second plate portion is disposed opposite to the main body portion.

[0008] In this design, the orthographic projection of the expansion board onto the first circuit board can cover both the first connector and the main body, thereby increasing the area of ​​the expansion board and reducing the layout complexity of the second functional components. Furthermore, it can increase the number of second functional components on the expansion board, thereby reducing the number of first functional components on the first circuit board and further improving the power supply's heat dissipation.

[0009] In some embodiments, the second functional device is disposed on the second board portion; the first board portion serves as the second connector portion, which is electrically connected to an external second circuit board. The first connector portion is used to transmit power signals; the second connector portion is used to transmit control signals.

[0010] The second connector for transmitting control signals and the first connector for transmitting power signals are respectively disposed on the expansion board and the first circuit board, thereby allowing the width of the first connector to be designed to be larger, which in turn increases the current-carrying area of ​​the power signals.

[0011] In some embodiments, the second functional device includes a power supply controller.

[0012] The control chip can receive control signals and control the first functional device in the voltage processing module according to the control signals.

[0013] In some embodiments, the first connector includes a first sub-connection and a second sub-connection, which are spaced apart; wherein the first sub-connection is used to transmit power signals and the second sub-connection is used to transmit control signals.

[0014] The power supply can be electrically connected to the second circuit board via the first sub-plug, thereby transmitting power signals to the second circuit board. Furthermore, the power supply can be electrically connected to the second circuit board via the second sub-plug, thereby receiving control signals from the second circuit board.

[0015] In some embodiments, there are multiple first functional devices; wherein at least one first functional device is disposed in a target area, the target area being the area of ​​the main body near the first insertion portion; among the first functional devices disposed in the target area, the height of a first number of first functional devices is less than the minimum height among the first functional devices disposed outside the target area. An extension board is disposed on the side of the first functional devices in the target area that faces away from the first circuit board; the projection of the extension board on the first circuit board at least covers a portion of the second functional devices.

[0016] The height of any first functional device disposed on the target area is less than the minimum height of the first functional devices in other areas of the main body. Since the first functional devices on the target area are lower, after the second plate of the first expansion board is disposed above the target area, it can be avoided that the top of the second functional device is too high after the second functional device is disposed on the first expansion board, thereby causing the power supply to be too large in the direction perpendicular to the first circuit board.

[0017] In some embodiments, the power supply further includes an extension adapter board; the extension board is disposed on the main body and electrically connected to the main body.

[0018] The expansion adapter board can be a circuit board, and some functional components can also be installed on the expansion adapter board, which can further increase the usable space inside the power supply, reduce the layout difficulty of functional components, and improve the heat dissipation effect of the power supply.

[0019] In some embodiments, the power supply also includes an adapter connector; the expansion board is disposed on the main body via the adapter connector and is electrically connected to the main body.

[0020] For example, the adapter connector may include pins. In this case, the expansion board and the main body can be electrically connected via the pins.

[0021] On the other hand, a computing device is provided. The computing device includes: a power supply as provided in any of the above embodiments and at least one second circuit board; wherein a first connector is electrically connected to the second circuit board.

[0022] The power supply is electrically connected to the second circuit board via the first connector, thereby supplying power to the devices mounted on the second circuit board. For example, the second circuit board may be a motherboard. Apart from this, the computing device described above has the same structure and beneficial technical effects as the power supply provided in some of the above embodiments, and will not be repeated here.

[0023] In some embodiments, the computing device further includes: a power adapter board and a first plug-in connector; wherein the power adapter board is electrically connected to a second circuit board; the first plug-in connector is disposed on the side of the power adapter board away from the second circuit board and is electrically connected to the power adapter board; the first plug-in connector is plugged into and electrically connected to a first plug-in portion.

[0024] The first connector may include a first sub-connector and a second sub-connector. The first sub-connector is used to transmit power signals, while the second sub-connector is used to transmit control signals. The first connector can be plugged into and electrically connected to the first connector. The first connector can also be electrically connected to the second circuit board via a power adapter board, allowing power to be supplied to the second circuit board and the components mounted on it. In this configuration, the first connector can transmit both control signals and power signals.

[0025] In some embodiments, the computing device further includes: a second plug-in connector. The second plug-in connector is disposed on the side of the power adapter board opposite to the second circuit board and is electrically connected to the power adapter board; the first plug-in connector and the second plug-in connector are spaced apart; the second plug-in connector is plugged into and electrically connected to the second plug-in portion.

[0026] In the case where the power supply includes a second plug-in portion, the first plug-in portion is used to transmit power signals, while the second plug-in portion is used to transmit control signals. The second plug-in portion is plugged into and electrically connected to a second plug-in connector, and the second plug-in connector can be electrically connected to a power adapter board. Thus, the second circuit board can transmit control signals to the second plug-in portion of the power supply. Attached Figure Description

[0055] Figure 1 This is a schematic diagram of the structure of a computing device according to some embodiments.

[0056] Please see Figure 1Some embodiments of this application provide a computing device 1000. For example, the computing device 1000 can be a general-purpose computing device or a dedicated computing device. For example, the computing device 1000 can be a server, switch, desktop computer, portable computer, PDA (Personal Digital Assistant), mobile phone, tablet computer, wireless terminal device, communication device, embedded device, etc. The embodiments of this application do not limit the type of computing device 1000.

[0057] exist Figure 1 The following is an illustration of computing device 1000 as an example of a server.

[0058] Please see Figure 1 The computing device 1000 includes a housing 100 and multiple power devices ( Figure 1 (not shown in the image) and power supply ( Figure 1 (Not shown in the image). The enclosure 100 includes a receiving space where multiple power devices and a power supply can be housed. The power supply can provide power to the multiple power devices.

[0059] For example, the enclosure 100 may include a main body and a lid, which are connected to each other to enclose the aforementioned receiving space. The connection between the main body and the lid can be detachable, in which case opening the lid exposes the various components inside the main body. Alternatively, the connection between the main body and the lid can be a snap-fit ​​connection. Other methods include detachable connections between the main body and the lid using screws, bolts, or pins.

[0060] For example, the main body of the box may include a bottom plate and multiple side plates, wherein the multiple side plates may be arranged along the edge of the bottom plate and the multiple side plates may be perpendicular to the bottom plate, and the bottom plate and the cover are respectively arranged on opposite sides of the multiple side plates.

[0061] For example, power components may include CPU (Central Processing Unit), GPU (Graphics Processing Unit), memory, network card, PCIe (Peripheral Component Interconnect Express) card, and hard drive, etc., which will not be listed here.

[0062] Figure 2 This is a schematic diagram of the internal planar structure of a computing device 1000 according to some embodiments.

[0063] Please see Figure 2The CPU 110, memory 120, network card 130, and PCIe card 140 are mounted on the motherboard 201. The motherboard 201 can be mounted on the backplane.

[0064] The power supply 300 can be electrically connected to the motherboard 201 to supply power to multiple power devices mounted on the motherboard 201.

[0065] In some examples, the number of power supplies 300 in computing device 1000 can be multiple, for example, the number of power supplies 300 can be two.

[0066] For example, multiple power supplies 300 can be arranged side by side on the base plate.

[0067] For example, multiple power supplies 300 are stacked, with the bottom power supply 300 located on the base plate.

[0068] Figure 3 This is a schematic diagram of the structure of a power supply 300 according to some embodiments. Wherein, in Figure 3 Two power supplies 300 are shown in the diagram. Figure 3 The two power supplies 300 can be arranged side by side on the bottom plate of the enclosure 100. For example, the two power supplies 300 are the first power supply 300A and the second power supply 300B.

[0069] Please see Figure 3 The power supply 300 may include: a housing 310, a power input interface 320, a first plug-in portion 332, and a plurality of functional devices (not shown in the figure) disposed within the housing 310.

[0070] In some examples, the power input interface 320 and the first plug-in portion 332 may be respectively located on opposite sides of the housing 310.

[0071] In some examples, the housing 310 includes multiple plates, from which the first plug portion 332 may extend. For example, the first plug portion 332 extends from a designated plate, which is provided with multiple heat dissipation vents 3100 to facilitate heat dissipation of the power supply 300.

[0072] In some examples, a fan may also be installed inside the housing 310. The fan can generate airflow to remove the heat generated by the power supply 300, thereby improving the heat dissipation effect of the power supply 300. The airflow generated by the fan can be blown out through the heat dissipation vent 3100.

[0073] The power input interface 320 can be located on one side of the housing 310. The power input interface 320 can be electrically connected to an external AC power source to input external AC power.

[0074] The power supply 300 may include a voltage processing module and a control module. It is understood that the power supply 300 includes multiple functional components, some of which may form a voltage processing module, while others may form a control module.

[0075] The power input interface 320 can be electrically connected to the voltage processing module, which can process AC power and convert it into DC power required by the target device.

[0076] Figure 4 for Figure 3 A schematic diagram of the structure when the power supply 300 is connected to the second circuit board 200.

[0077] Please see Figure 4 The first connector 332 can be electrically connected to the power processing module, and can also be electrically connected to the second circuit board 200 (i.e., the target device) outside the power supply 300, thereby sending the power signal required by the second circuit board 200 to the second circuit board 200, so that the power supply 300 can provide power to the devices on the second circuit board 200 that require power. For example, the second circuit board 200 can be the aforementioned motherboard 201 (such as...). Figure 2 (As shown).

[0078] The control module can be electrically connected to the voltage processing module. The control module can generate control signals and control the voltage processing module according to these signals. For example, the first connector 332 can also be electrically connected to the control module, allowing the control module to interact with the second circuit board 200 via the first connector 332 to exchange control signals. For example, the control signals can come from a BMC (Baseboard Management Controller) and / or CPLD (Complex Programmable Logic Device) located on the motherboard 201.

[0079] Please see Figure 4 The computing device 1000 may further include a plug-in connector 400, one end of which can be electrically connected to the second circuit board 200, and the other end of which can be connected to the first plug-in portion 332 (e.g., Figure 3 As shown, the power supply 300 can be electrically connected to the second circuit board 200 through the first plug-in part 332 and the plug-in connector 400.

[0080] At this time, as Figure 4 As shown, the first connector 332 (as shown) Figure 3 As shown in the figure, the space above the plug connector 400 is not occupied by any other devices and is in an idle state.

[0081] Figure 5 This is a structural schematic diagram of the first circuit board inside the power supply 300 and the functional devices disposed on the first circuit board.

[0082] Please see Figure 5 The power supply 300 may further include a first circuit board 330, which includes a main body 331 and a first connector 332 located at one end of the main body 331. A power input interface 320 is electrically connected to the main body 331. Multiple functional devices may be disposed on the main body 331. The first connector 332 may connect to a second circuit board 200 (such as...). Figure 2 (As shown) Electrical connection, so that power supply 300 can supply power to multiple components on the second circuit board 200.

[0083] In some examples, the first circuit board 330 may also include an input section 333, which may be housed in a housing 310 (e.g., Figure 2 The power input interface 320 (as shown) extends from the cavity enclosed by the cavity. Figure 3 (As shown) can be provided on the input section 333. For example, the input section 333 can be located on the side of the main body 331 away from the first plug-in section 332.

[0084] For example, the voltage processing module may include multiple functional devices. For example, the multiple functional devices may include a filter circuit 610, a rectifier circuit 620, a power factor correction (PFC) circuit 630, a soft-start circuit 640, and a DC-DC converter circuit 650.

[0085] Conductive lines are provided in the first circuit board 330, and multiple functional devices on the first circuit board 330 can be electrically connected through the conductive lines.

[0086] The filter circuit 610 can be electrically connected to the power input interface 320. The filter circuit 610 can filter out burst pulses and high-frequency interference in the AC signal received by the power input interface 320, and can reduce electromagnetic interference from the power supply 300 to the power grid. For example, the filter circuit 610 may include two stages of common-mode inductors 611, wherein the two stages of common-mode inductors 611 may include two inductors connected in series.

[0087] The rectifier circuit 620 can be electrically connected to the filter circuit 610, and the power factor correction circuit 630 can be electrically connected to the rectifier circuit 620. The rectifier circuit 620 and the power factor correction circuit 630 can work together to improve the power factor of the power supply 300.

[0088] For example, rectifier circuit 620 may include a half-wave rectifier circuit or a full-wave rectifier circuit.

[0089] For example, the power factor correction circuit 630 may include electronic components such as a switching transistor, an inductor 631, and a capacitor 632.

[0090] The soft-start circuit 640 can work in conjunction with the DC-DC converter circuit 650 to convert a high-voltage AC signal into a low-voltage DC signal. For example, the soft-start circuit 640 and the DC-DC converter circuit 650 can convert a high-voltage AC signal into a 12V low-voltage DC signal.

[0091] For example, the DC-DC converter circuit 650 includes a transformer 651 and a resonant inductor 652.

[0092] In related technologies, the first circuit board 330 not only houses multiple functional devices from the voltage processing module, but also a control module and its peripheral circuits, resulting in a high power density in the power supply 300 and consequently, poor heat dissipation. In the power supply 300, power density can be understood as the ratio of the power of the power supply 300 to its volume.

[0093] Based on this, some embodiments of this application provide a power supply 300.

[0094] Figure 6 This is another structural schematic diagram of the power supply 300 according to some embodiments. Figure 7 for Figure 6 Main view of power supply 300; Figure 8 for Figure 6 Left view of power supply 300.

[0095] Please see Figure 6 , Figure 7 and Figure 8 The power supply 300 includes a first circuit board 330, an expansion board 340, and multiple functional devices (not shown in the figure).

[0096] The first circuit board 330 includes a main body 331 and a first insertion part 332. An expansion board 340 is disposed on the main body 331 and electrically connected to the main body 331. For example, the expansion board 340 can be electrically connected to the first circuit board 330 via an adapter connector. Alternatively, the expansion board 340 can be electrically connected to the first circuit board 330 via an expansion adapter board 350.

[0097] The multiple functional devices include a first functional device and a second functional device, wherein the first functional device is disposed on the main body 331 and electrically connected to the main body 331; and the second functional device is disposed on the expansion board 340 and electrically connected to the expansion board 340.

[0098] In some examples, there are multiple first functional devices, which together form a voltage processing module. For example, the multiple first functional devices may include the filter circuit 610, rectifier circuit 620, power factor correction circuit 630, soft-start circuit 640, and DC-DC converter circuit 650 described above.

[0099] In some of the embodiments described above, the first circuit board 330 and the voltage processing module disposed on the first circuit board 330 have been described, and will not be repeated here.

[0100] In some examples, the second functional device can be used in the aforementioned control module. For example, there can be multiple second functional devices, which may include the controller of the power supply 300. For example, the controller of the power supply 300 may include multiple control chips. The controller of the power supply 300 can generate control signals and send them to the voltage processing module to control the first functional device in the voltage processing module. For example, the control signals may include power status signals, presence signals, and power signals, etc. For example, the control signals can be low-speed signals, and for example, the control signals can be transmitted via an I2C (Inter-Integrated Circuit) bus.

[0101] In addition, the second functional device may also include resistors and switching transistors used in conjunction with the controller of the power supply 300.

[0102] The expansion board 340 is provided with conductive lines, and multiple secondary functional devices disposed on the expansion board 340 can be connected through the conductive lines in the expansion board 340.

[0103] The second functional device can be located on the side of the expansion board 340 opposite to the first circuit board 330.

[0104] exist Figures 6-8 In this case, the number of expansion boards 340 can be one.

[0105] Figure 9 This is yet another structural schematic diagram of a power supply 300 according to some embodiments.

[0106] Please see Figure 9 The number of expansion boards 340 can also be multiple. For example, the number of expansion boards 340 can be 2, 3, 4, etc., which will not be listed here. Figure 9 In this paper, taking two expansion boards 340 as an example, some embodiments of this application are illustrated.

[0107] For example, the expansion board 340 can be arranged parallel to the first circuit board 330. When there are multiple expansion boards 340, all of them can be arranged parallel to the first circuit board 330.

[0108] In some embodiments of this application, by setting an expansion board 340, some functional devices, such as second functional devices, are disposed on the expansion board 340, thereby increasing the wiring layout space on the first circuit board 330, which can improve the heat dissipation effect of the power supply 300. In addition, the increased wiring layout space on the first circuit board 330 can also reduce the layout difficulty of the functional devices inside the power supply 300.

[0109] Furthermore, the projection of the expansion board 340 onto the first circuit board 330 at least covers a portion of the first connector 332. In some examples, the orthographic projection of the expansion board 340 onto the first circuit board 330 completely covers the first connector 332. In another example, the orthographic projection of the expansion board 340 onto the first circuit board 330 partially covers the first connector 332.

[0110] At this time, an extension plate 340 can be provided above the first plug-in part 332, wherein "above the first plug-in part 332" refers to the side of the first plug-in part 332 away from the bottom plate of the housing 100.

[0111] In the prior art, the space above the first plug-in portion 332 is not used and remains idle. However, in some embodiments of this application, the space above the first plug-in portion 332 can be used to install an expansion board 340, thereby increasing the usable space in the power supply 300, increasing the volume of the power supply 300, reducing power density, and improving the heat dissipation of the power supply 300. In addition, the increased usable space within the power supply 300 can also reduce the difficulty of layout of functional components within the power supply 300.

[0112] Furthermore, by utilizing the space above the first plug-in portion 332 to install the expansion board 340, the volume of the power supply 300 can be increased without increasing the space occupied by the power supply 300 on the bottom plate of the housing 100.

[0113] Please continue reading. Figures 6-8 In other examples, the power supply 300 also includes an expansion adapter board 350. An expansion board 340 is disposed on and electrically connected to the main body 331 via the expansion adapter board 350. The expansion adapter board 350 may be a circuit board.

[0114] The direction of the main body 331 pointing to the first plug-in part 332 is the first direction F1, and the second direction F2 is perpendicular to the first direction F1 and parallel to the first circuit board 330.

[0115] The first circuit board 330 may include a first edge 335 and a second edge 336 disposed opposite each other in the second direction F2. The first insertion portion 332 is strip-shaped, and the extension direction of the first insertion portion 332 intersects the extension directions of the first edge 335 and the second edge 336. For example, the first insertion portion 332 extends along the second direction F2, while the first edge 335 and the second edge 336 may both extend along the first direction F1.

[0116] The expansion adapter board 350 can be disposed on one side of the first circuit board 330. For example, the expansion adapter board 350 can be disposed along the first edge 335 or the second edge 336. For example, the expansion adapter board 350 can be parallel to the first direction F1. In this case, the expansion adapter board 350 connected to one side of the first circuit board 330 can extend along the first direction F1.

[0117] For example, the expansion adapter 350 may be perpendicular to the first circuit board 330, and the expansion board 340 may be perpendicular to the expansion adapter 350.

[0118] In some examples, a first connection socket can be provided on one of the expansion adapter board 350 and the first circuit board 330, and a first connection plug can be provided on the other. The first connection plug can be plugged into and electrically connected to the first connection socket, thereby achieving relative fixation and electrical connection between the expansion adapter board 350 and the first circuit board 330.

[0119] In some examples, a second connection socket can be provided on one of the expansion adapter board 350 and the expansion board 340, and a second connection plug can be provided on the other. The second connection plug can be plugged into and electrically connected to the second connection socket, thereby achieving a relatively fixed and electrically connected relationship between the expansion adapter board 350 and the expansion board 340.

[0120] In some embodiments, the first circuit board 330 may also be provided with a support post, and the side of the support post away from the first circuit board 330 is provided with a threaded hole. The expansion plate 340 may be provided with a mounting hole, and fasteners can enter the threaded hole through the mounting hole to fix the expansion plate 340 and the first circuit board 330 relative to each other. This arrangement can improve the stability of the expansion plate 340 installation, thereby avoiding instability in the installation of the expansion plate 340.

[0121] In some examples, the multiple functional devices may also include a third functional device, which may be disposed on the expansion adapter board 350. By disposing of the third functional device on the expansion adapter board 350, the usable space within the power supply 300 can be increased, thereby reducing the power density of the power supply 300 and improving its heat dissipation.

[0122] The third functional device may include the controller of the power supply 300 and at least some of the peripheral circuitry.

[0123] In some examples, the power supply 300 may also include a stand plate, which may be fixed relative to and electrically connected to the first circuit board 330. For example, the stand plate and the extension adapter plate 350 may be disposed along a first edge 335 and a second edge 336, respectively. The stand plate may be a circuit board. For example, the stand plate may be perpendicular to the first circuit board 330. Some of the multiple second functional devices may also be disposed on the stand plate. By providing a stand plate in the power supply 300, the usable space within the power supply 300 can be further increased, thereby reducing the number of functional devices on the first circuit board 330, and thus improving the heat dissipation effect of the power supply 300.

[0124] In some embodiments, the power supply 300 may further include a fixing member, which may be fixedly connected to the housing 310. The fixed connection means that after the fixing member is connected to the housing 310, the two are relatively fixed, and their relative positional relationship does not change. For example, the fixing member and the housing 310 may be connected by welding, snap-fitting, or other methods.

[0125] The fastener can also be fixedly connected to the expansion plate 340, thereby fixing the expansion plate 340. For example, the fastener and the expansion plate 340 can be connected by screws, bolts or other structures.

[0126] In some of the above embodiments, the expansion board 340 is electrically connected to the first circuit board 330 via the expansion adapter board 350. In other embodiments, the expansion board 340 and the first circuit board 330 can also be connected via an adapter connector.

[0127] In some examples, the power supply 300 also includes an adapter connector; the expansion board 340 is disposed on and electrically connected to the main body 331 via the adapter connector. For example, the adapter connector can be a pin, which can be disposed on the expansion board 340. As another example, the adapter connector can include a connecting plug and a connecting slot, wherein one of the connecting plug and the connecting slot can be disposed on and electrically connected to the expansion board 340, while the other of the connecting slots can be disposed on and electrically connected to the first circuit board 330. The connecting plug can be inserted into and electrically connected to the connecting slot, thereby electrically connecting the first circuit board 330 and the expansion board 340.

[0128] Please see Figure 6 and Figure 7In some embodiments, the expansion board 340 includes a first board portion 3411 and a second board portion 3412, the first board portion 3411 and the second board portion 3412 being electrically connected; wherein, the first board portion 3411 is disposed opposite to the first plug-in portion 332; and the second board portion 3412 is disposed opposite to the main body portion 331.

[0129] The first plate portion 3411, when projected onto the first circuit board 330, does not cover the main body portion 331, but covers the first plug portion 332.

[0130] The second board portion 3412 is projected onto the first circuit board 330, covering a portion of the main body portion 331, but not covering the first plug portion 332.

[0131] In this design, the first board portion 3411 is disposed opposite to the first insertion portion 332; the second board portion 3412 is disposed opposite to the main body portion 331. Therefore, the orthographic projection of the expansion board 340 onto the first circuit board 330 can cover both the first insertion portion 332 and the main body portion 331, thereby increasing the area of ​​the expansion board 340 and reducing the layout difficulty of the second functional devices. Furthermore, it can increase the number of second functional devices on the expansion board 340, thereby reducing the number of first functional devices on the first circuit board 330 and further improving the heat dissipation effect of the power supply 300.

[0132] Figure 10 This is another structural schematic diagram of a power supply 300 according to some embodiments.

[0133] Please see Figure 10 In some examples, the first plate portion 3411 and the second plate portion 3412 may both be located within the housing 310. In this case, multiple second functional devices may be disposed on the first plate portion 3411 and the second plate portion 3412.

[0134] In some embodiments, the receiving cavity enclosed by the housing 310 includes a first receiving cavity 311 and a second receiving cavity 312, which are sequentially arranged and connected along a first direction F1. The first direction F1 extends from the main body 331 to the first insertion portion 332; as shown... Figure 6 As shown, the direction pointed to by arrow F1 is the first direction.

[0135] The main body 331 is disposed within the first receiving cavity 311, and the first insertion part 332 extends out from the first receiving cavity 311. A power input interface 320 is provided (e.g., ...). Figure 3 The input section 333 (shown) is located outside the housing 310 and on the side of the first receiving cavity 311 opposite to the first plug-in section 332.

[0136] The second receiving cavity 312 and the first plug portion 332 are spaced apart in a direction perpendicular to the first circuit board 330. The portion of the expansion plate 340 whose orthogonal projection on the first circuit board 330 can cover the first plug portion 332 is located in the second receiving cavity 312. For example, the first plate portion 3411 is located in the second receiving cavity 312.

[0137] Wherein, the dimension H1 of the second receiving cavity 312 in the direction perpendicular to the first circuit board 330 is smaller than the dimension H2 of the first receiving cavity 311 in the direction perpendicular to the first circuit board 330.

[0138] In some examples, housing 310 includes a first plate 3101 and a second plate 3102 disposed opposite to each other, wherein a first circuit board 330 may be disposed on the first plate 3101, and the width of the first plate 3101 in the first direction F1 is smaller than the width of the second plate 3102 in the first direction F1.

[0139] The housing 310 also includes a third plate 3103 and a fourth plate 3104 and a fifth plate 3105 disposed opposite to the third plate 3103, wherein the fourth plate 3104 and the fifth plate 3105 are both disposed opposite to the third plate 3103. The fifth plate 3105 is closer to the third plate 3103 than the fourth plate 3104.

[0140] The two opposite edges of the third plate 3103 are connected to the first plate 3101 and the second plate 3102 respectively, the fourth plate 3104 is connected to the second plate 3102, and the fifth plate 3105 is connected to the first plate 3101.

[0141] The housing 310 also includes a sixth plate 3106, which is disposed opposite to the second plate 3102 and is closer to the second plate 3102 than the first plate 3101. The sixth plate 3106 includes two opposing edges, one of which connects to an edge of the fourth plate 3104 away from the second plate 3102, and the other edge connects to an edge of the fifth plate 3105 away from the first plate 3101. In other words, the two opposing edges of the sixth plate 3106 are respectively connected to the fourth plate 3104 and the fifth plate 3105.

[0142] For example, the sixth plate 3106 may be spaced apart from the first plug portion 332 in a direction perpendicular to the first circuit board 330.

[0143] In addition, the housing 310 also includes a seventh plate and an eighth plate disposed opposite to each other, wherein the seventh plate and the eighth plate are both connected to the first plate 3101 to the sixth plate 3106 described above, and the first plate 3101 to the sixth plate 3106 are located between the seventh plate and the eighth plate. The first plate 3101 to the eighth plate form a receiving cavity.

[0144] The first plate 3101, the third plate 3103, part of the second plate 3102, part of the seventh plate, and part of the eighth plate can form the first receiving cavity 311, while the sixth plate 3106, the fourth plate 3104, part of the second plate 3102, part of the seventh plate, and part of the eighth plate can form the second receiving cavity 312.

[0145] For example, the width of the sixth plate 3106 in the first direction F1 can be 29mm, the width of the sixth plate 3106 in the second direction F2 can be 50mm, and the width of the fourth plate 3104 in the direction perpendicular to the first circuit board 330 can be 33mm. Therefore, the volume of the second receiving cavity 312 can be equal to 29mm × 50mm × 33mm. The first direction F1 points from the main body 331 to the first insertion part 332. The second direction F2 is perpendicular to the first direction F1 and parallel to the first circuit board 330. Figure 10 In the middle, the second direction F2 can be a direction perpendicular to the paper and outwards.

[0146] The second receiving cavity 312 can provide space for the first plate portion 3411.

[0147] By providing a second receiving cavity 312 within the housing 310, the space above the first insertion portion 332 can be fully utilized, increasing the internal space of the housing 310. In the prior art, the space above the first insertion portion 332 is unused. Therefore, by providing a second receiving cavity 312 above the first insertion portion 332, the space already used within the housing 100 is not occupied, and thus, the layout of other components within the housing 100 does not need to be changed.

[0148] For example, the first plate portion 3411 is located on the side of the sixth plate body 3106 opposite to the first plug portion 332.

[0149] For example, the first plug-in portion 332 of the first circuit board 330 can extend from the fifth board body 3105, in which case the fifth board body 3105 can be the aforementioned specified board.

[0150] For example, the input section 333 of the first circuit board 330 can extend from the third board body 3103. In this case, the power input interface 320 can be located on the side of the third board body 3103 away from the fourth board body 3104.

[0151] In some examples, the fourth plate 3104 and / or the fifth plate 3105 may be provided with heat dissipation vents 3100 (e.g. Figure 3 (As shown), this improves the heat dissipation of the power supply 300.

[0152] In some examples, the expansion adapter board 350 can be perpendicular to the fourth board 3104 and the fifth board 3105, wherein the fourth board 3104 and the fifth board 3105 can be provided with heat dissipation vents 3100. This arrangement can prevent the expansion adapter board 350 from blocking the heat dissipation vents 3100, thereby reducing the impact of the expansion adapter board 350 on the heat dissipation of the power supply 300.

[0153] Figure 11 for Figure 10 A schematic diagram of the structure of the first circuit board 330, wherein... Figure 11 The first functional device disposed on the first circuit board 330 was removed.

[0154] Please see Figure 11 In some embodiments, there are multiple first functional devices; at least one first functional device is disposed in the target area 3311, which is the area of ​​the main body 331 near the first insertion portion 332; among the first functional devices disposed in the target area 3311, the height of a first number of first functional devices is less than the minimum height of the first functional devices disposed outside the target area 3311. An extension plate 340 is disposed on the side of the first functional devices in the target area 3311 that faces away from the first circuit board 330; the projection of the extension plate 340 on the first circuit board 330 at least covers a portion of the second functional devices.

[0155] The second direction F2 is parallel to the first circuit board 330 and perpendicular to the first direction F1. Figure 11 In the diagram, the direction indicated by arrow F2 is the second direction.

[0156] The target area 3311 includes multiple edges, among which a first edge is connected to the first plug-in portion 332.

[0157] In some examples, the width of the target region 3311 in the second direction F2 may be smaller than the width of the main body 331 in the second direction F2. In this case, other regions of the main body 331 may be arranged around multiple edges of the target region 3311, excluding the first edge.

[0158] In some examples, the width of the first insertion portion 332 in the second direction F2 may be smaller than the width of the main body portion 331 in the second direction F2. The width of the target region 3311 in the second direction F2 may be equal to the width of the first insertion portion 332 in the second direction F2.

[0159] In other examples, the width of the target region 3311 in the second direction F2 may be equal to the width of the main body 331 in the second direction F2.

[0160] Among the first functional devices disposed in the target area 3311, the height of a first number of first functional devices is less than the minimum height of the first functional devices disposed outside the target area 3311. Specifically, the height of any first functional device disposed in the target area 3311 is less than the minimum height of the first functional devices in other areas of the main body 331.

[0161] For example, multiple capacitors can be disposed on the target area 3311, wherein the height of the capacitors is low and lower than the height of the first functional devices on other areas of the main body 331. In the prior art, the area above the target area 3311 is idle. Therefore, in some of the above embodiments, the second plate portion 3412 of the first expansion plate 341 is disposed above the target area 3311. By making the orthographic projection of the second plate portion 3412 on the first circuit board 330 cover the target area 3311, the usable space inside the power supply 300 can be further increased, the power density of the power supply 300 can be reduced, and the heat dissipation effect of the power supply 300 can be improved.

[0162] In addition, since the first functional device on the target area 3311 is relatively low, after setting the second board portion 3412 of the first expansion board 341 above the target area 3311, it can be avoided that the top of the second functional device is too high after the second functional device is set on the first expansion board 341, which would result in the power supply 300 being too large in the direction perpendicular to the first circuit board 330.

[0163] In some examples, the side of the second functional device facing away from the first circuit board 330 can be made approximately flush with the side of the first functional device facing away from the first circuit board 330. Of course, in other examples, the side of the second functional device facing away from the first circuit board 330 can be lower than the side of the first functional device facing away from the first circuit board 330. This arrangement ensures that the height of the housing 310 of the power supply 300 in the direction perpendicular to the first circuit board 330 is approximately equal to the height of the housing 310 in the same direction in the prior art. Therefore, the space occupied by the power supply 300 within the housing 100 can remain unchanged, thus eliminating the need to adjust the layout of other components within the housing 100 to accommodate the power supply 300 provided in some embodiments of this application.

[0164] Please continue reading. Figure 11In some embodiments, the first plug portion 332 includes a first sub-plug portion 3321 and a second sub-plug portion 3322, which are spaced apart; the first sub-plug portion 3321 is used to transmit power signals, and the second sub-plug portion 3322 is used to transmit control signals.

[0165] For example, the second sub-connector 3322 can be electrically connected to the control module. The control module can be connected to an external controller through the second sub-connector 3322. The control module is used to send relevant detection signals or status signals of the power supply, and to receive external control signals, and to control the voltage processing module of the internal circuit of the power supply accordingly based on the control signals. For example, the external controller can be located on the second circuit board 200.

[0166] For example, the first sub-plug 3321 can be electrically connected to the voltage processing module, and the voltage processing module can output a low-voltage DC signal through the first sub-plug 3321. For example, the low-voltage DC signal can be a DC voltage signal such as 12V, 48V, or 54V.

[0167] In some examples, the first sub-plug portion 3321 and the second sub-plug portion 3322 extend along the same edge of the main body portion 331. For example, this edge may extend along the second direction F2. In this case, the first sub-plug portion 3321 and the second sub-plug portion 3322 are arranged sequentially along the second direction F2.

[0168] The first sub-plug portion 3321 and the second sub-plug portion 3322 are spaced apart, thereby avoiding short circuit between the first sub-plug portion 3321 and the second sub-plug portion 3322.

[0169] For example, the first sub-plug portion 3321 and the second sub-plug portion 3322 can be gold fingers disposed on the first plug portion 332.

[0170] In some examples, the first sub-connection portion 3321 may include a positive electrode region 3321A and a ground region 3321B spaced apart along the extending direction of the edge of the main body portion 331. The spaced-apart arrangement of the positive electrode region 3321A and the ground region 3321B prevents a short circuit between them. For example, the positive electrode region 3321A and the ground region 3321B are arranged sequentially along the second direction F2. When the power supply 300 supplies power to the second circuit board 200, the voltages of the positive electrode region 3321A and the ground region 3321B are different.

[0171] For example, the grounding region 3321B can be located between the positive region 3321A and the second sub-plug portion 3322.

[0172] Figure 12This is a schematic planar structure diagram of the first insertion portion 332 according to some embodiments.

[0173] Please see Figure 12 The second sub-connector 3322 may include multiple connection terminals, which may extend along a third direction and be arranged sequentially along that direction. Different connection terminals may be used to transmit different control signals. For example... Figure 12 As shown, the direction pointed to by arrow F3 is the third direction, which is perpendicular to the second direction F2 and parallel to the first insertion part 332.

[0174] For example, some connection terminals on the third direction F3 are shorter than the lengths of the remaining connection terminals on the third direction F3. Among the multiple connection terminals with longer lengths, some can be ground terminals. Ground terminals are used to transmit ground signals. The longer length of the ground terminals allows them to receive the ground signal first, thereby improving the phenomenon of signal overshoot.

[0175] For example, the width of the grounding region 3321B on the third direction F3 is greater than the width of the positive region 3321A on the third direction F3.

[0176] For example, the width L5 of the first sub-connector 3321 in the second direction F2 is 35mm. For example, the effective current-passing width L6 of the second sub-connector 3322 in the second direction F2 is 13mm. The effective current-passing width refers to the width of the portion of the second sub-connector 3322 where the gold fingers are located in the second direction F2.

[0177] Figure 13 for Figure 10 A schematic diagram of the structure when the power supply 300 is electrically connected to the second circuit board 200.

[0178] Please see Figure 13 In some embodiments, the computing device 1000 further includes a first plug-in connector 410. One end of the first plug-in connector 410 can be electrically connected to the second circuit board 200. The other end of the first plug-in connector 410 can be plugged into and electrically connected to the first plug-in portion 332.

[0179] For example, the first plug connector 410 is provided with a receiving groove, and when the first plug connector 410 is plugged into the first plug part 332, the first plug part 332 can be disposed in the receiving groove.

[0180] In some embodiments, in the first direction F1, the end of the first plate portion 3411 extends beyond the end of the first plug portion 332.

[0181] In the first direction F1, the end of the first plate portion 3411 refers to the end of the first plate portion 3411 that is away from the second plate portion 3412. And in the first direction F1, the end of the first insertion portion 332 refers to the end of the first insertion portion 332 that is away from the main body portion 331.

[0182] In this context, the fact that the end of the first plate portion 3411 extends beyond the end of the first plug portion 332 in the first direction F1 can be understood as the orthographic projection of the end of the first plate portion 3411 away from the housing 310 onto the first circuit board 330 being located on the side of the first plug portion 332 away from the main body portion 331. Furthermore, it can also be understood that the width L1 of the first plate portion 3411 in the first direction F1 is greater than the width L2 of the first plug portion 332 in the first direction F1.

[0183] The length of the first plug connector 410 in the first direction F1 is greater than the length of the first plug portion 332 in the first direction F1. When the first plug portion 332 is plugged into the first plug connector 410, at least a portion of the first plug connector 410 can be located below the first plate portion 3411. Therefore, the arrangement of the first expansion plate 341 can also utilize the space above the first plug connector 410, thereby increasing the usable space within the housing 310 of the power supply 300, increasing the volume of the power supply 300, thereby reducing the power density of the power supply 300 and improving the heat dissipation effect of the power supply 300.

[0184] Figure 14 This is yet another structural schematic diagram of a computing device 1000 according to some embodiments.

[0185] Please see Figure 14 In some other embodiments, in the first direction F1, the end of the first plate portion 3411 away from the second plate portion 3412 is flush with the end of the first plug portion 332 away from the main body portion 331. In this case, the width L1 of the first plate portion 3411 in the first direction F1 is equal to the width L2 of the first plug portion 332 in the first direction F1.

[0186] Please continue reading. Figure 13 and Figure 14 In some embodiments, the computing device 1000 may further include a power adapter board 500. The power adapter board 500 is electrically connected to the second circuit board 200, and a first plug-in connector 410 may be disposed on the side of the power adapter board 500 opposite to the second circuit board 200 and electrically connected to the power adapter board 500. The first plug-in connector 410 is plugged into and electrically connected to the first plug-in portion 332.

[0187] In some examples, the power adapter board 500 can be connected to at least one second circuit board 200, so that the power supply 300 can supply power to at least one second circuit board 200 and the components disposed thereon. Figure 13 and Figure 14 In this paper, taking the connection between the power adapter board 500 and two second circuit boards 200 as an example, some embodiments of this application are illustrated.

[0188] In cases where there are multiple second circuit boards 200, the multiple second circuit boards 200 can be arranged in parallel.

[0189] For example, the second circuit board 200 can be set perpendicular to the power adapter board 500.

[0190] For example, the power adapter board 500 can be positioned perpendicular to the first circuit board 330.

[0191] In some examples, the computing device 1000 may include multiple power supplies 300. In this case, multiple first plug-in connectors 410 may be provided on the power adapter board 500. The multiple first plug-in connectors 410 can be plugged into the first plug-in portions 332 of the multiple power supplies 300 respectively. Thus, the multiple power supplies 300 can be electrically connected to at least one second circuit board 200 through the multiple first plug-in connectors 410 and the power adapter board 500, so that the multiple power supplies 300 can supply power to at least one second circuit board 200.

[0192] In some of the above embodiments, by providing multiple power supplies 300 in the computing device 1000, when some power supplies 300 fail, the remaining power supplies 300 can still supply power to the components in the computing device 1000, thereby ensuring the normal operation of the computing device 1000.

[0193] Multiple power supplies 300 can be arranged side by side on the bottom plate of the enclosure 100, or they can be stacked sequentially on the bottom plate of the enclosure 100.

[0194] In some of the above embodiments, the first plate portion 3411 and the second plate portion 3412 are both disposed inside the housing, and the second functional device is disposed on the first plate portion 3411 and the second plate portion 3412.

[0195] Figure 15 This is another structural schematic diagram of a power supply 300 according to some embodiments.

[0196] Please see Figure 15 In some embodiments, the second functional device may be disposed on the second board portion 3412; the first board portion 3411 serves as a second plug-in portion, which is electrically connected to the external second circuit board 200; wherein the first plug-in portion is used to transmit power signals; and the second plug-in portion is used to transmit control signals. In this case, the first board portion 3411, which serves as the second plug-in portion, may extend from the housing 310.

[0197] In some examples, the orthographic projection of the first plate portion 3411 onto the first circuit board 330 covers the first plug portion 332. In this case, the orthographic projection of the first plate portion 3411 onto the first circuit board 330 can partially cover the first plug portion 332, or the orthographic projection of the first plate portion 3411 onto the first circuit board 330 can completely cover the first plug portion 332.

[0198] The first connector 332 can be electrically connected to the voltage processing module, and the voltage processing module can output a low-voltage DC signal through the first connector 332.

[0199] The first board portion 3411 can be electrically connected to the control module. The control module can be electrically connected to an external controller through the first board portion 3411 to receive control signals from the external controller and control the voltage processing module according to the control signals. For example, the external controller can be set on the second circuit board 200, and the first board portion 3411 can be electrically connected to the second circuit board 200, so that the control module can receive control signals through the first board portion 3411.

[0200] In some examples, the distance between the end of the first plate portion 3411 away from the second plate portion 3412 and the housing 310 can be equal to the distance between the end of the first insertion portion 332 away from the main body portion 331 and the housing 310.

[0201] The distance between the end of the first plate portion 3411 away from the second plate portion 3412 and the housing 310 can be understood as the width of the first plate portion 3411 in the first direction F1, and the distance between the end of the first plug portion 332 away from the main body portion 331 and the housing 310 can be understood as the width of the first plug portion 332 in the first direction F1.

[0202] Figure 16 for Figure 15 A schematic diagram of the planar structure of the first circuit board 330, wherein, in Figure 16 The first functional device disposed on the first circuit board 330 was removed.

[0203] Please see Figure 16 In some examples, the first connector 332 may include a positive region 3321A and a ground region 3321B, wherein the positive region 3321A is used to transmit a positive voltage signal, and the ground region 3321B is used to transmit a ground signal.

[0204] In some of the above embodiments, the second plug portion for transmitting control signals and the first plug portion 332 for transmitting power signals are respectively disposed on the expansion board 340 and the first circuit board 330, so that the width of the first plug portion 332 in the second direction F2 can be designed to be larger, thereby increasing the current flow area of ​​the power signal.

[0205] Figure 17 for Figure 15 Top view of the first circuit board 330 connected to the expansion board 340.

[0206] Please see Figure 17 In some examples, the orthographic projection of the first plate portion 3411 onto the first circuit board 330 may cover a portion of the first plug portion 332.

[0207] In some examples, the orthographic projection of the first plate portion 3411 on the first circuit board 330 may be located at one end of the first plug portion 332 in the second direction F2. In this case, the orthographic projection of one end of the first plate portion 3411 in the second direction F2 on the first circuit board 330 may overlap with one end of the first plug portion 332 in the second direction F2.

[0208] In other examples, the orthographic projection of the first plate portion 3411 onto the first circuit board 330 may be located at the center of the first plug portion 332.

[0209] Figure 18 for Figure 17 A schematic diagram of the structure of the first plate portion 3411 projected onto the first insertion portion 332, wherein, in Figure 18 The main body 331 of the first circuit board 330 and the second board 3412 of the expansion board 340 are not shown in the figure.

[0210] Please see Figure 18 In some examples, the width of the first insertion portion 332 in the second direction F2 is L3, and the effective current passage width of the first plate portion 3411 in the second direction F2 is L4. The effective current passage width refers to the width of the portion of the first plate portion 3411 on which the gold fingers are provided in the second direction F2. In this case, L3 is greater than L4.

[0211] For example, 3×L4≤L3≤4.5×L4.

[0212] Specifically, by ensuring that the width L3 of the first connector 332 in the second direction F2 is greater than or equal to 3 × L4, it is possible to avoid the first connector 332 having an excessively small width L3 in the second direction F2, which would result in an excessively small current-carrying width for the power signal. Furthermore, the width of the first circuit board 330 in the second direction F2 is positively correlated with the width L3 of the first connector 332 in the second direction F2. By ensuring that the width L3 of the first connector 332 in the second direction F2 is ≤ 4.5 × L4, it is possible to avoid the first connector 332 having an excessively large width L3 in the second direction F2, which would result in an excessively large width of the first circuit board 330 in the second direction F2, thereby preventing the power supply 300 from becoming too large.

[0213] For example, L4 = 3.8 × L3.

[0214] For example, L4 = 13mm; L3 = 49.5mm.

[0215] In some other examples, the width of the first insertion portion 332 in the second direction F2 can be L3, which is equal to the effective flow width of the first plate portion 3411 in the second direction F2.

[0216] Figure 19 This is another structural schematic diagram of a power supply 300 according to some embodiments.

[0217] Please see Figure 19 In some embodiments, the power supply 300 may include a plurality of expansion boards 340. For example, the plurality of expansion boards 340 includes a first expansion board 341 and a second expansion board 342. The second expansion board 342 is located between the first expansion board 341 and the first circuit board 330. The first portion 3411 of the second expansion board 342 serves as a second connector, and the second portion 3412 of the second expansion board 342 is located within the housing 310. Both the first portion 3411 and the second portion 3412 of the first expansion board 341 are located within the housing 310. The second connector is used to transmit control signals, and the first connector 3412 is used to transmit power signals.

[0218] At this time, the housing 310 can form a first receiving cavity 311 and a second receiving cavity 312. The first plate portion 3411 of the first extension plate 341 is disposed in the second receiving cavity 312, and the second plate portion 3412 is disposed in the first receiving cavity 311.

[0219] The second plate portion 3412 of the second extension plate 342 is located in the first receiving cavity 311, and the first plate portion 3411 extends out of the housing 310.

[0220] The plurality of second functional devices may include a first part of second functional devices and a second part of second functional devices; the first part of second functional devices is disposed on the first plate portion 3411 and the second plate portion 3412 of the first expansion plate 341, while the second part of second functional devices is disposed on the second plate portion 3412 of the second expansion plate 342.

[0221] In some examples, the width of the first portion 3411 of the first expansion plate 341 in the first direction F1 can be greater than the width of the first portion 3411 of the second expansion plate 342 in the first direction F1. In this case, the area of ​​the first portion 3411 of the first expansion plate 341 is larger, thus providing more usable space for the arrangement of the second functional device.

[0222] In some examples, some second functional devices may be provided on the first board portion 3411 of the second expansion board 342. In other examples, the second expansion board 342 may not have any functional devices provided. In this case, the functional devices on the second expansion board 342 can be prevented from blocking the heat dissipation vent 3100 and affecting the heat dissipation of the power supply 300.

[0223] In other examples, the width of the first plate portion 3411 of the first extension plate 341 in the first direction F1 may be less than or equal to the width of the first plate portion 3411 of the second extension plate 342 in the first direction F1.

[0224] In some examples, the width of the second portion 3412 of the first expansion board 341 in the first direction F1 can be greater than the width of the second portion 3412 of the second expansion board 342 in the first direction F1. In this case, a small number of second functional devices can be provided on the second portion 3412 of the second expansion board 342. In this example, because the width of the second portion 3412 of the second expansion board 342 in the first direction F1 is small, the space occupied by the second portion 3412 of the second expansion board 342 inside the housing 310 can be reduced. Furthermore, because the distance between the second portion 3412 of the second expansion board 342 and the first circuit board 330 is small, and the width of the second portion 3412 of the second expansion board 342 is small, interference between the second portion 3412 of the second expansion board 342 and the first functional devices on the main body 331 of the first circuit board 330 can be avoided.

[0225] In other examples, the width of the second plate portion 3412 of the first extension plate 341 in the first direction F1 may also be less than or equal to the width of the second plate portion 3412 of the second extension plate 342 in the first direction F1.

[0226] Figure 20 for Figure 19 A schematic diagram of the structure when the power supply 300 is electrically connected to the second circuit board 200.

[0227] Please see Figure 20 In the case where the power supply 300 also includes a second plug-in portion, the computing device 1000 further includes: a second plug-in connector 420; the second plug-in connector 420 is disposed on the side of the power adapter board 500 away from the second circuit board 200 and is electrically connected to the power adapter board 500; the first plug-in connector 410 and the second plug-in connector 420 are disposed at a distance; the second plug-in connector 420 is plugged into and electrically connected to the second plug-in portion.

[0228] The first plug connector 410 has already been described above, so it will not be repeated here.

[0229] For example, a second insertion slot may be provided on the second insertion connector 420, and when the second insertion connector 420 is electrically connected to the second insertion part, the second insertion part may be located in the second insertion slot.

[0230] in, Figure 20 The assembly consisting of the first connector 410, the second connector 420, and the power adapter board 500 can also be used in... Figure 8 The power supply 300 includes the second connector.
