[0002] There are many ways to connect the PDB and the motherboard of existing servers, including using Micro-Hi 3mm PitchPower connectors and cables to interconnect the PDB (Power Distribution Board) and the motherboard, and using customized copper bars to interconnect the PDB and the motherboard.

The connectors and cables take up a lot of space on the motherboard and PDB board, affecting the layout design.

[0059] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0060] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0061] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0062] The present application discloses a power supply system, the structural diagram of which is shown in FIG. Figure 1 As shown, including:

[0063] The main board 11 , the power supply component 12 and the first connector 13 .

[0064] Wherein, the mainboard 11 has at least part of the circuit system of the electronic device;

[0065] The power supply component 12 can supply power to at least a part of the circuit system of the mainboard;

[0066] The first connector 13 is fixedly connected to the mainboard 11 and is used to directly connect to the power supply component so that the power supply component can supply power to at least a part of the circuit system of the mainboard;

[0067] The first connector 13 has a first pin group for configuring the first information and a second pin group for configuring the second information. The first pin group is different from the second pin group so that when the power supply component 12 is directly connected to the first connector 13, it is electrically connected to the mainboard by adapting different pin groups.

[0068] The power supply for the mainboard usually needs to pass through the server PDB (Power Distribution Board), that is, the power supply board component, and transfer the power to the mainboard through the PDB to power at least part of the circuit system on the mainboard.

[0069] The connection between the PDB and the motherboard usually requires multiple Micro-Hi 3mm Pitch Power connectors and cables, or the PDB and the motherboard are interconnected using customized copper bars or copper pillars. However, these methods all have some problems. For example, for the method of connecting the PDB and the motherboard through multiple Micro-Hi 3mm Pitch Power connectors and cables, it usually requires multiple Micro-Hi 3mm Pitch Power connectors and more cables, which leads to large space occupation, affecting layout design, and high cost. For the method of interconnecting the PDB and the motherboard using customized copper bars or copper pillars, since customized copper bars or copper pillars are expensive, the cost of adopting this method is high, and the structures of different servers are different, resulting in poor reusability of customized copper bars or copper pillars, further increasing the cost.

[0070] Based on this, in this solution, the power supply component and the mainboard are interconnected through the first connector, so that the power supply component can power at least part of the circuit system on the mainboard through the first connector. There is no need for multiple Micro-Hi 3mm PitchPower connectors and a large number of cables, which avoids the problem of occupying a large space and affecting the layout design. At the same time, the connection between the mainboard and the power supply component is achieved only through the first connector. The first connector can be connected between different mainboards and power supply components, and can be reused without the need for customized operations, further reducing costs.

[0071] Specifically, the power supply system disclosed in this embodiment includes: a mainboard, a power supply component and a first connector. The first connector is fixed on the mainboard and can be directly connected to the power supply component to connect the power supply component to the mainboard, so that the power supply component can supply power to at least part of the circuit system on the mainboard.

[0072] The main board can be a main board of a server or a main board of an electronic device. A circuit system for realizing at least part of the functions of the server or the electronic device is arranged on the main board. When the power supply component is connected to the main board through the first connector, the power supply component can supply power to at least part of the circuit system on the main board.

[0073] The first connector may specifically be a CRPS (Card Rack Power Supply) connector. The CRPS connector is a connector used in a server power supply system and can support high-current and high-density power supply connections.

[0074] The first connector has at least a first pin group and a second pin group, wherein the first pin group is used to configure the first information, and the second pin group is used to configure the second information, and the pins included in the first pin group and the pins included in the second pin group are different pins in the first connector, such as: the first pin group includes the first pin and the second pin, the second pin group includes the third pin and the fourth pin, and the first pin, the second pin, the third pin and the fourth pin are different pins on the first connector.

[0075] The first information and the second information are different information from the power supply component. After the power supply component is connected to the mainboard through the first connector, the power supply component can transmit the first information to the mainboard through the first pin group of the first connector so that the mainboard can obtain the first information. The power supply component can also transmit the second information to the mainboard through the second pin group of the first connector so that the mainboard can obtain the second information.

[0076] After the mainboard is connected to the power supply component through the first connector, the first information and the second information cannot be obtained from the power supply component immediately. Instead, the power supply component sends the first information to the mainboard only when the power supply component satisfies the first condition, and sends the second information to the mainboard only when the power supply component satisfies the second condition, and the first condition is different from the second condition;

[0077] The first condition may be that the power supply component is connected to the mainboard via the first pin group of the first connector, and the second condition may be that the power supply component is connected to the mainboard via the second pin group of the first connector.

[0078] Alternatively, only when the power supply component meets the first condition, the power supply component will generate the first information and send the first information to the mainboard through the first pin group of the first connector; only when the power supply component meets the second condition, the power supply component will generate the second information and send the second information to the mainboard through the second pin group of the first connector.

[0079] The power supply system disclosed in this embodiment includes a mainboard, a power supply component and a first connector, wherein the mainboard has at least part of the circuit system of the electronic device; the power supply component can supply power to at least part of the circuit system of the mainboard; the first connector is fixedly connected to the mainboard and is used to directly connect the power supply component so that the power supply component can supply power to at least part of the circuit system of the mainboard; the first connector has a first pin group for configuring the first information and a second pin group for configuring the second information, and the first pin group is different from the second pin group, so that when the power supply component is directly connected to the first connector, it is electrically connected to the mainboard by adapting different pin groups. In this solution, the first connector is fixed on the mainboard, and the first connector is directly connected to the mainboard, so that the power supply component supplies power to at least part of the circuit system of the mainboard through the first connector, and only through the first connector, it can be realized that at least part of the circuit system on the mainboard is powered, without a large number of connectors and cables, avoiding the problem of large space occupation caused by a large number of connectors and cables, and avoiding the impact on the layout; at the same time, the connection between the power supply component and the mainboard is realized only through the first connector, which is low in cost, and different power supply components and mainboards can use the same first connector, which is highly reusable and easy to maintain.

[0080] This embodiment discloses a power supply system, and its structural diagram is shown in FIG. Figure 2a As shown, including:

[0081] Main board 21 , power supply component 22 and first connector 23 .

[0082] In addition to the same structure as the previous embodiment, the power supply component 22 in this embodiment includes:

[0083] The power supply board assembly 221 and the power supply assembly 222 .

[0084] The first side of the power supply board assembly 221 has a first connector in the form of a gold finger, the first connector is adapted to the first connector 23, and can be connected by direct plugging, and the second side of the power supply board assembly 221 is provided with a second connector;

[0085] The power supply component 222 has a second connector in the form of a gold finger, which is adapted to the second connector and can be connected by direct plugging.

[0086] Specifically, Figure 2b As shown, it includes: a main board 21, a power supply component 22 and a first connector 23, wherein the power supply component 22 includes: a power supply board component 221 and a power supply component 222, the power supply board component 221 includes: a first connector 2211 and a second connector 2212, the power supply component 222 includes a second connector, wherein the second connector is Figure 2b Not shown in the figure.

[0087] In this embodiment, the power supply component is composed of a power supply board assembly and a power supply assembly. The power supply assembly is connected to the power supply board assembly, and the power supply board assembly is connected to the main board through a first connector, so that the power supply assembly can supply power to at least part of the circuit system on the main board.

[0088] The power supply board assembly is connected to the mainboard through a first connector, and the first connector is fixed on the mainboard. The power supply board assembly and the first connector are connected by direct plugging, that is, the power supply board assembly has a first connector, and the first connector is adapted to the first connector. When the first connector is directly plugged into the first connector, a direct connection between the power supply board assembly and the first connector on the mainboard is realized.

[0089] The first connector of the power board assembly can be in the form of a gold finger, and the power board assembly is connected to the first connector on the mainboard through the first connector in the form of a gold finger, so as to realize a direct connection between the power board assembly and the mainboard. The first connector in the form of a gold finger has the characteristics of reliable connection and easy maintenance, and its manufacturing and material costs are low, so that the cost of the first connector is low.

[0090] The first connector on the power supply board assembly is located on the first side of the power supply board assembly, and a second connector is also arranged on the second side of the power supply board assembly for connecting with the power supply assembly.

[0091] The power supply assembly has a second connector, and the power supply assembly is connected to the second connector on the power supply board assembly through the second connector. The second connector and the second connector are adapted to each other. When the second connector and the second connector are directly plugged in, the power supply assembly is directly connected to the power supply board assembly.

[0092] Among them, the second connector can be specifically in the form of a gold finger. The power supply component is plugged into the second connector on the power supply board component through the second connector in the form of a gold finger. At the same time, the power supply board component is plugged into the first connector fixed on the mainboard through the first connector in the form of a gold finger. The power supply component supplies power to at least part of the circuit system on the mainboard through the first connector fixed on the mainboard and the second connector on the power supply board component. This can be achieved through only two gold finger-shaped connectors, without the need to use multiple Micro-Hi 3mm Pitch Power connectors and cables, thus avoiding the impact on the design layout; there is no need to use customized copper bars or copper columns to interconnect the PDB with the mainboard, thus avoiding the increase in cost, reducing the volume occupied in the electronic device, facilitating PCB layout and mechanism design, and requiring no additional wiring space.

[0093] The power supply system disclosed in this embodiment includes: a mainboard, a power supply component and a first connector, wherein the power supply component includes a power supply board assembly and a power supply assembly, the first side of the power supply board assembly has a first connector in the form of a gold finger, the first connector is adapted to the first connector, and can be connected by direct plugging, and the second side of the power supply board assembly is provided with a second connector; the power supply assembly has a second connector in the form of a gold finger, the second connector is adapted to the second connector, and can be connected by direct plugging. In this solution, the power supply component includes a power supply board assembly and a power supply assembly, the power supply assembly is connected to the power supply board assembly, the power supply board assembly can be connected to the first connector by direct plugging, and the power supply assembly is used to supply power to at least part of the circuit system on the mainboard through the switching of the power supply board assembly, and when the power supply assembly is connected to the mainboard through the switching of the power supply board assembly, the connection can be achieved through the first connector and the second connector, without adding other connectors and cables, thereby avoiding the problem of large space occupied by a large number of connectors and cables, avoiding the impact on the layout, and reducing costs.

[0094] Furthermore, in the power supply system disclosed in this embodiment, the power supply component may include: a first power supply and a second power supply.

[0095] The first power source has a first power connector in the form of a gold finger; the second power source has a second power connector in the form of a gold finger.

[0096] Correspondingly, the second connector includes: a first power connector and a second power connector.

[0097] The first power connector is configured with a first sub-information, is fixedly connected to the power supply board assembly, is adapted to the first power supply connector of the first power supply, and can be connected by direct plugging; the second power connector is configured with a second sub-information, is fixedly connected to the power supply board assembly, is adapted to the second power supply connector of the second power supply, and can be connected by direct plugging.

[0098] like Figure 3 As shown, it includes: a mainboard 31, a power supply component 32 and a first connector 33. The power supply component 32 includes: a power supply board component 321 and a power supply component 322, wherein the power supply board component includes a second connector, and the second connector includes a first power supply connector 3211 and a second power supply connector 3212; the power supply component 322 includes: a first power supply 3221 and a second power supply 3222.

[0099] The power supply assembly is composed of two power supplies, and correspondingly, the second connector in the power supply board assembly is also composed of two power connectors, so that the two power supplies can be connected to the mainboard through the power supply board assembly, so as to power at least part of the circuit system in the mainboard through the two power supplies, thereby ensuring the power supply in the mainboard and avoiding the situation where at least part of the circuit system in the mainboard cannot operate normally due to lack of power supply due to power supply abnormality.

[0100] The first power supply and the second power supply can be two independent power supplies in the power supply assembly. The first power supply is connected to the first power connector on the power supply board assembly, and the second power supply is connected to the second power connector on the power supply board assembly. The power supply board assembly is connected to the mainboard through the first connector, so that the first power supply and the second power supply respectively supply power to at least part of the circuit system on the mainboard. At this time, even if an abnormality occurs in the first power supply, or an abnormality occurs in the line between the first power supply and the first power connector, resulting in failure to supply power to at least part of the circuit system on the mainboard, the second power supply will continue to supply power to at least part of the circuit system on the mainboard and will not be affected by the first power supply. Therefore, the two power supplies are connected to the power supply board assembly to supply power to at least part of the circuit system on the mainboard.

[0101] When the first power supply and the second power supply are two unrelated power supplies in the power supply component, the first power supply and the second power supply can be the same power supply or different power supplies; in addition, the first power supply is connected to the first power connector to power the first part of the circuit system on the main board, and the second power supply is connected to the second power connector to power the second part of the circuit system on the main board, wherein the first part of the circuit system and the second part of the circuit system can be the same part of the same circuit system, different parts of the same circuit system, or parts of different circuit systems.

[0102] The mainboard may be a mainboard on a server, and the circuit system on the mainboard of the server may include: a power-on circuit, a power supply circuit, a clock circuit, a reset circuit, a BIOS circuit, an interface circuit, a CMOS circuit, etc. The power-on circuit is used to detect the power switch state and control the power on and off of the mainboard; the power supply circuit is used to ensure that the various components of the server obtain a stable power supply; the clock circuit can provide a stable clock signal to ensure that the various components inside the server run synchronously; the reset circuit can reset the server state when necessary to ensure the stability and reliability of the server; the BIOS circuit is used to store the information of the basic input and output system to control the server startup process; the interface circuit is used to provide various interface connections to connect external devices; and the CMOS circuit is used to save the basic settings and time information of the server.

[0103] In this embodiment, the first power supply can control the power-on circuit and power supply circuit on the mainboard, and the second power supply controls the clock circuit, reset circuit, BIOS circuit, interface circuit and CMOS circuit on the mainboard, that is, the first power supply supplies power to the first part of the circuit system on the mainboard, and the second power supply supplies power to the second part of the circuit system on the mainboard, and the first part of the circuit system and the second part of the circuit system are different circuit parts on the server; or, the first power supply controls the power-on circuit, power supply circuit and clock circuit on the mainboard, and the second power supply is also used to control the power-on circuit, power supply circuit and clock circuit on the mainboard, that is, the first power supply supplies power to the first part of the circuit system on the mainboard, and the second power supply supplies power to the second part of the circuit system on the mainboard, and the first part of the circuit system and the second part of the circuit system are the same circuit part on the server.

[0104] Alternatively, the power supply component is a 1+1 redundant power supply component, that is, the second power supply is a redundant power supply of the first power supply, the first power supply is connected to the first power connector on the power supply board component, and the second power supply is connected to the second power connector on the power supply board component. Under normal conditions, the first power supply supplies power to at least part of the circuit system on the main board through the first power connector, the power supply board component and the first connector. When the first power supply is abnormal, or the line between the first power supply and the first power connector is abnormal, and at least part of the circuit system on the main board cannot be powered, the second power supply is enabled, and the second power supply supplies power to at least part of the circuit system on the main board through the second power connector, the power supply board component and the first connector, to ensure that even if one power supply is abnormal and cannot supply power, there is still a redundant power supply to provide electrical energy, avoiding the situation where power cannot be supplied due to power supply abnormality.

[0105] Among them, the power connector of the first power supply is in the shape of a gold finger, and the connection between the first power connector in the shape of a gold finger and the first power connector in the second connector of the power supply board assembly is realized; the power connector of the second power supply is in the shape of a gold finger, and the connection between the second power supply and the power supply board assembly is realized by plugging the second power connector in the shape of a gold finger and the second power connector in the second connector of the power supply board assembly.

[0106] In addition, the first power connector is also configured with first sub-information, and the second power connector is configured with second sub-information.

[0107] Among them, the first sub-information and the second sub-information are used to distinguish the first power connector and the second power connector. When the first power connector is plugged with the first power supply and the second power connector is plugged with the second power supply, if the first power supply is exactly the same as the second power supply and the first power connector is exactly the same as the second power connector, the motherboard cannot determine whether it is the first power supply or the second power supply that supplies power to at least part of its circuit system. Therefore, the first power connector and the second power connector can be distinguished by the first sub-information and the second sub-information, so that after the first power supply is connected to the motherboard through the first power connector and the second power supply is connected to the motherboard through the second power connector, the sub-information corresponding to the power connector can be used to determine which power supply is provided, or which power supply outputs information.

[0108] Among them, the first sub-information and the second sub-information can be specifically address information, such as: the first sub-information represents the address information of the first power connector, and the second sub-information represents the address information of the second power connector; or, the first sub-information and the second sub-information can also be specifically identification information, such as: the first sub-information represents the identification information of the first power connector, and the second sub-information represents the identification information of the second power connector; of course, the first sub-information and the second sub-information can also be other information, which will not be repeated here.

[0109] The power supply system disclosed in this embodiment includes: a mainboard, a power supply component and a first connector, wherein the power supply component includes a power supply board assembly and a power supply assembly, the first side of the power supply board assembly has a first connector in the form of a gold finger, the first connector is adapted to the first connector, and can be connected by direct plugging, and the second side of the power supply board assembly is provided with a second connector; the power supply assembly has a second connector in the form of a gold finger, the second connector is adapted to the second connector, and can be connected by direct plugging; wherein the power supply assembly includes a first power supply and a second power supply, the first power supply has a first power supply connector in the form of a gold finger, and the second power supply has a second power supply connector in the form of a gold finger; the second connector includes a first power supply connector and a second power supply connector, the first power supply connector is configured with a first sub-information, is fixedly connected to the power supply board assembly, is adapted to the first connector of the first power supply, and can be connected by direct plugging, and the second power supply connector is configured with a second sub-information, is fixedly connected to the power supply board assembly, is adapted to the second power supply connector of the second power supply, and can be connected by direct plugging. In this solution, the first power supply and the second power supply are connected to the power supply board component through the first power connector and the second power connector respectively, and are connected to the first connector fixed on the mainboard through the power supply board component, so as to power at least part of the circuit system on the mainboard through the first power supply and the second power supply to ensure the power supply in the mainboard and avoid the situation where at least part of the circuit system in the mainboard cannot operate normally due to lack of power supply due to power supply abnormality.

[0110] Further, based on the above embodiments disclosed as Figure 3 On the basis of the power supply system shown, the first connector is adapted to the first connector and can be connected by direct plugging, and may include:

[0111] If the first power supply is connected to the first power connector, the first connector matches the first information of the first pin group with the first sub-information of the first power connector to electrically connect the first power supply to the mainboard; if the second power supply is connected to the second power connector, the first connector matches the second information of the second pin group with the second sub-information of the second power connector to electrically connect the second power supply to the mainboard.

[0112] The first connector has a first pin group and a second pin group. The mainboard can obtain first information through the first pin group of the first connector, and the mainboard can obtain second information through the second pin group of the first connector. The first information is the first information configured for the first pin group. After the first power supply is connected to the mainboard through the first pin group of the first connector, the mainboard can obtain the first information configured for the first pin group. The second information is the second information configured for the second pin group. After the second power supply is connected to the mainboard through the second pin group of the first connector, the mainboard can obtain the second information configured for the second pin group.

[0113] based on Figure 3 In the power supply system shown, the first connector 33 is arranged on the main board 31, the power supply board assembly 321 in the power supply component 32 is connected to the first connector 33, and a second connector is arranged on the power supply board assembly 321. The second connector includes a first power connector 3211 and a second power connector 3212. The first power connector 3211 is connected to the first power supply 3221, and the second power connector 3212 is connected to the second power supply 3222.

[0114] That is, the power supply circuit of the first power supply is: the first power supply 3221 is connected to the mainboard through the first power connector 3211, the power supply board assembly 321 and the first connector 31 in sequence, so as to supply power to at least part of the circuit system on the mainboard; the power supply circuit of the second power supply is: the second power supply 3222 is connected to the mainboard through the second power connector 3212, the power supply board assembly 321 and the first connector 31 in sequence, so as to supply power to at least part of the circuit system on the mainboard.

[0115] The power supply line of the first power supply coincides with the data output line of the data in the first power supply, and the power supply line of the second power supply coincides with the data output line of the data in the second power supply. Since both the line of the first power supply and the line of the second power supply need to pass through the first connector, in order to avoid the motherboard being unable to determine whether the power or data is transmitted from the first power supply or the second power supply after the power or data is transmitted to the motherboard, the power or data output by different power supplies can be transmitted through different pin groups on the first connector.

[0116] Therefore, as long as it is determined that the first power supply is connected to the first power connector, the data output by the first power supply is transmitted through the first pin group on the first connector; as long as it is determined that the second power supply is connected to the second power connector, the data output by the second power supply is transmitted through the second pin group on the first connector.

[0117] The first information of the first pin group on the first connector can be matched with the first sub-information of the first power connector, so that only the data transmitted by the first power connector corresponding to the matching first sub-information can be received through the first pin group on the first connector, that is, only the data transmitted by the first power can be received through the first pin group on the first connector; correspondingly, the second information of the second pin group on the first connector can be matched with the second sub-information of the second power connector, so that only the data transmitted by the second power connector corresponding to the matching second sub-information can be received through the second pin group on the first connector, that is, only the data transmitted by the second power can be received through the second pin group on the first connector.

[0118] After matching the first information with the first sub-information, the following path is realized: mainboard-first pin group of the first connector-power supply board component-first power connector-first power supply, the first power supply can transmit data to the mainboard through this path, and after receiving the data transmitted by the first pin group, the mainboard can directly determine based on the matching relationship that the received data is transmitted by the first power supply; if the first information of the first pin group does not match the first sub-information of the first power connector, after receiving the data transmitted by the first pin group, the mainboard cannot determine that the received data is transmitted by the first power supply because the first information of the first pin group does not match any information;

[0119] Correspondingly, after matching the second information with the second sub-information, the following path is realized: mainboard-second pin group of the first connector-power supply board assembly-second power connector-second power supply. The second power supply can transmit data to the mainboard through this path. After receiving the data transmitted by the second pin group, the mainboard can directly determine based on the matching relationship that the received data is transmitted by the second power supply. If the second information of the second pin group does not match the second sub-information of the second power connector, after receiving the data transmitted by the second pin group, the mainboard cannot determine that the received data is transmitted by the second power supply because the second information of the second pin group does not match any information.

[0120] The above method realizes that the first power supply and the second power supply can transmit data to the mainboard through a first connector, and the power supply of at least part of the circuit system on the mainboard is realized only through one connector, and the risk of load imbalance is relatively small; and the data output by different power supplies can be transmitted through different pin groups on the first connector, so that the information received by different pin groups can be distinguished from which power supply the obtained data is output, thereby ensuring that when different power supplies output data to the mainboard, the source of the data can be determined.

[0121] This embodiment discloses a power supply system, including:

[0122] A main board, a power supply component and a first connector. The power supply component includes: a power supply board component and a power supply component.

[0123] Among them, the first connector of the power supply board assembly is directly connected to the first connector along the first direction, and the second connector of the power supply assembly is directly connected to the second connector, so that the first surface of the power supply assembly meets the parallel condition with the surface of the mainboard.

[0124] Specifically, the schematic diagram is as follows Figure 4a As shown, including:

[0125] Main board 41 , power supply component 42 and first connector 43 . The power supply component 42 includes: a power supply board assembly 421 and a power supply assembly 422 . The power supply board assembly 421 includes a first connector 4211 and a second connector 4212 . The power supply assembly 422 includes a second connector 4221 .

[0126] Among them, the first connector 4211 of the power supply board assembly 421 is directly plugged into the first connector 43, and the power supply assembly 422 is directly plugged into the second connector 4212 of the power supply board assembly 421 through the second connector 4221, so as to realize powering at least part of the circuit system on the mainboard 41 through the power supply assembly 422.

[0127] In addition, it should be emphasized that Figure 4a In the embodiment, the first connector 4211 of the power supply board assembly 421 is directly connected to the first connector 43 along a first direction so that the first surface of the power supply assembly meets the parallel condition with the surface of the mainboard.

[0128] in, Figure 4a The direction indicated by the middle arrow is the first direction, which is parallel to the mainboard. When the mainboard is placed horizontally, the first direction is parallel to the mainboard and faces the mainboard. After the power supply board assembly is plugged into the mainboard along the first direction, the power supply board assembly and the mainboard are parallel. After the power supply assembly is plugged into the power supply board assembly, the power supply assembly is also parallel to the mainboard, thereby realizing the horizontal docking of the power supply assembly and the mainboard.

[0129] in, Figure 4a FIG. 4 is a schematic diagram showing a power supply connected to a mainboard along a first direction via a power supply board assembly 421. Figure 4b It is a schematic diagram showing that two power supplies are connected to the main board along a first direction via the power supply board assembly 421 .

[0130] Figure 4b The main board 41, the power supply component 42 and the first connector 43 are included. The power supply component 42 includes a power supply board assembly 421 and a power supply assembly 422. The power supply board assembly 421 includes a first connector 4211 and a second connector. The second connector includes a first power connector 4212a and a second power connector 4212b. The power supply assembly 422 includes a first power supply 422a and a second power supply 422b. The first power supply 422a includes a second connector 4221a. The second power supply 422b includes a second connector 4221b.

[0131] In addition, after the power supply board assembly is connected to the mainboard through the first connector, the position of the power supply board assembly will be located above the side of the mainboard relative to the mainboard. Thereafter, after the power supply assembly is connected to the power supply board assembly through the second connector, the power supply assembly will also be located above the side of the power supply board assembly. This will cause the power supply assembly to be raised secondary relative to the mainboard, which is not conducive to the design of the system structure. Therefore, in this solution, a sunken connector can be directly used as the second connector on the power supply board assembly, so that after the power supply assembly is connected to the power supply board assembly using the sunken connector, the plane where the power supply assembly is located is lowered relative to the plane where the power supply board assembly is located. At the same time, the first connector does not change, and the plane where the power supply assembly is located is located on the same horizontal plane relative to the mainboard, and no height difference will be generated, which is conducive to the design of the system structure.

[0132] In addition, the schematic diagram of the power supply system disclosed in this embodiment can also be as follows Figure 5 As shown, including:

[0133] Main board 41 , power supply component 42 and first connector 43 . The power supply component 42 includes: a power supply board assembly 421 and a power supply assembly 422 . The power supply board assembly 421 includes a first connector 4211 and a second connector 4212 . The power supply assembly 422 includes a second connector 4221 .

[0134] Among them, the first connector 4211 of the power supply board assembly 421 is directly plugged into the first connector 43, and the power supply assembly 422 is directly plugged into the second connector 4212 of the power supply board assembly 421 through the second connector 4221, so as to realize powering at least part of the circuit system on the mainboard 41 through the power supply assembly 422.

[0135] In addition, it should be emphasized that Figure 5 In the embodiment, the first connector 4211 of the power supply board assembly 421 is directly connected to the first connector 43 along the second direction so that the second surface of the power supply assembly meets the parallel condition with the surface of the mainboard.

[0136] The first direction is perpendicular to the second direction. When the first direction is parallel to the surface of the mainboard, the second direction is perpendicular to the surface of the mainboard. Figure 5 The direction indicated by the solid arrow is the second direction. When the motherboard is placed in parallel, the second direction is perpendicular to the motherboard and faces the motherboard, and the power board assembly is perpendicular to the motherboard and plugged into the motherboard. At this time, the power board assembly is perpendicular to the motherboard. After that, the power supply assembly is plugged into the power board assembly along the direction parallel to the motherboard, which can be Figure 5 The direction indicated by the dotted arrow in the figure can also be other directions parallel to the mainboard and perpendicular to the direction indicated by the current dotted arrow to achieve the vertical docking of the power supply board assembly with the mainboard.

[0137] When the power supply assembly is connected to the mainboard along the second direction through the power supply board assembly, the power supply assembly may include a power supply such as Figure 5 As shown, two power supplies may also be included, which is not specifically limited here.

[0138] In addition, after the power supply board assembly is connected to the mainboard through the first connector, the position of the power supply board assembly will be above the mainboard relative to the mainboard. Thereafter, after the power supply assembly is connected to the power supply board assembly through the second connector, the power supply assembly will also be located above the side of the power supply board assembly. This will cause the power supply assembly to be raised secondary relative to the mainboard, which is not conducive to the design of the system structure. Therefore, in this solution, a sunken connector can be directly used as the second connector on the power supply board assembly, so that after the power supply assembly is connected to the power supply board assembly using the sunken connector, the plane where the power supply assembly is located is lowered relative to the plane where the power supply board assembly is located. At the same time, the first connector does not change, and the plane where the power supply assembly is located is lowered to a certain extent relative to the mainboard, avoiding a high height difference, which is beneficial to the design of the system structure.

[0139] Furthermore, if the size of the power supply assembly is raised too large, that is, when the power supply board assembly in this embodiment is vertically connected to the main board, the second connector on the power supply board assembly can be directly designed to be rotated 180 degrees along the line where the first direction is located, so that the power supply assembly can be inserted upside down into the power supply board assembly after rotating 180 degrees, so as to reduce the height of the power supply assembly and achieve the purpose of keeping the relative position of the power supply assembly relative to the main board unchanged.

[0140] It should be noted that when the power supply board assembly is plugged into the first connector along the first direction, the structure of the first connector is different from that when the power supply board assembly is plugged into the first connector along the second direction. When the power supply board assembly is plugged into the first connector along the first direction, the interface of the first connector is horizontal, and the first connector head of the power supply board assembly is inserted into the first connector horizontally; when the power supply board assembly is plugged into the first connector along the second direction, the interface of the first connector is facing upward, and the first connector head of the power supply board assembly is inserted into the first connector vertically.

[0141] This embodiment discloses a power supply system, including:

[0142] A main board, a power supply component and a first connector.

[0143] In addition to the same structure as the above embodiment, the power supply component in this embodiment includes a power supply assembly.

[0144] The structural diagram of the power supply system disclosed in this embodiment is as follows Figure 6 As shown, including:

[0145] Main board 61 , power supply assembly 62 and first connector 63 .

[0146] Among them, the power supply component 62 has a second connector in the form of a gold finger, the second connector is adapted to the first connector 63, and can be connected by direct plug. The first connector 63 matches the second information of the second pin group with the third sub-information of the power supply component 62 to electrically connect the power supply component 62 to the mainboard 61.

[0147] The power supply component disclosed in this embodiment only includes a power supply assembly, which is directly connected to the mainboard through the first connector without passing through the power supply board assembly.

[0148] The first connector can only be connected to one connector. If a redundant power supply is not needed, there is no need for switching through the power supply board assembly, and it can be directly plugged into the mainboard through the power supply assembly, reducing the devices required to power the mainboard and avoiding the increased possibility of power supply abnormalities due to the need for switching through the power supply board assembly.

[0149] Specifically, when testing, no redundant power supply is required. At this time, the power supply component can be directly connected to the mainboard through the first connector; in actual use, a redundant power supply is usually required to ensure the normal operation of the mainboard. Therefore, in actual use, it is usually necessary to switch the power board component to ensure that the mainboard is powered by the first power supply and the second power supply.

[0150] When the power supply component is directly plugged into the mainboard through the first connector, the power supply component is plugged into the first connector with a second connector in the form of a gold finger, and the second connector is adapted to the first connector to achieve the connection between the power supply component and the mainboard.

[0151] When the power supply assembly is directly plugged into the mainboard through the first connector, the second information of the first connector through the second pin group is matched with the third sub-information of the power supply assembly to electrically connect the power supply assembly to the mainboard.

[0152] The third sub-information of the power supply component may be identification information, address information or sideband information of the power supply component, wherein the sideband information may include a control signal and / or a detection signal.

[0153] Match the second information of the second pin group of the first connector with the third sub-information of the power supply component so that the mainboard can clearly identify which power supply component is currently connected to the mainboard, and that the information is transmitted through the second pin group, that is, the information transmitted through the second pin group is all information transmitted from the power supply component, so as to achieve the purpose of accurately determining the source of the information.

[0154] Furthermore, in the power supply system disclosed in this embodiment, the power supply board component may be connected to the mainboard through the first connector, and the power supply component supplies power to at least part of the circuit system on the mainboard through the power supply board component; or: the power supply component may be directly connected to the mainboard through the first connector, and the power supply component directly supplies power to at least part of the circuit system on the mainboard. Therefore, in order to identify whether the power supply component directly plugged into the first connector is only the power supply component, or is composed of the power supply board component and the power supply component, the first connector in this embodiment is also provided with a third pin group for configuring third information.

[0155] Specifically, some pins of the third pin group are the same as some pins of the first pin group and / or the second pin group, and the third pin group is used to identify the power supply component of the direct plug connection.

[0156] The third pin group is mainly used to identify whether the power supply component directly connected to the first connector is a power supply component or a power supply board component. When the power supply component directly connected to the first connector is a power supply component, the information obtained by the third pin group is different from the information obtained by the third pin group when the power supply component directly connected to the first connector is a power supply board component. Therefore, when a power supply component is directly connected to the first connector, the power supply component directly connected to the first connector can be identified based on the information obtained by the third pin group.

[0157] The third pin group may be a pin group on the first connector dedicated to identifying a power supply component directly connected to the first connector, or may be a pin group composed of pins in a pin group with other functions on a reused first connector, such as: the third pin group includes a plurality of pins, the plurality of pins included may include some pins in the first pin group, and may also include some pins in the second pin group, the third pin group is composed of some pins in the first pin group, or the third pin group is composed of some pins in the second pin group, or the third pin group is composed of some pins in the first pin group and some pins in the second pin group, or the third pin group is composed of some pins in the first pin group and some pins in the remaining pins, or the third pin group is composed of some pins in the second pin group and some pins in the remaining pins, or the third pin group is composed of some pins in the first pin group, some pins in the second pin group and some pins in the remaining pins. The remaining pins are other pins on the first connector except the first pin group and the second pin group.

[0158] by Figure 7 The first connector shown is used as an example for explanation, wherein the P series pins are pins on the first connector for current flow, i.e., for transmitting electrical energy, and the S series pins are pins on the first connector for transmitting sideband signals, i.e., transmitting control signals and / or detection signals.

[0159] Among them, the S1 pin and S2 pin of the first connector are I2C protocol buses. The mainboard communicates with the I2C device on the link through the I2C protocol of the S1 pin and S2 pin. The data transmitted through the S1 pin and S2 pin of the first connector may include: voltage, current, power consumption, temperature, set mode status, fan control, FW upgrade and downgrade, redundancy setting, etc.; the S3 pin of the first connector is used to transmit the control signal of power on and off; the S4 pin is used to transmit the alarm Alert signal of sensors such as registers or temperature sensors; the S5 pin and the S6 pin are used to transmit the alarm Alert signal of sensors such as registers or temperature sensors. It is a feedback resistor; the S7 pin is used to transmit the DCOK signal for the completion of AC-DC power-on; the S8 and S9 pins are used to configure the address of the power connector. By configuring the address of the power connector, the two power supplies connected to the power supply board component can be distinguished; the S11 and S12 pins are used together to balance the two power supplies, and are used to detect the load voltage and determine the working mode of the two AC power supplies; the S13 pin is used to transmit the power supply in place PRSNT signal; the S14 pin is used to transmit the ACOK signal for the completion of AC signal power-on.

[0160] When a power supply component is directly connected to the mainboard through the first connector, the connection between the power supply component and the mainboard is achieved through the second pin group of the first connector, wherein the second pin group may include: S4 pin, S7 pin, S13 pin and S14 pin, and each corresponding signal in the power supply component is transmitted to the mainboard through each pin in the above-mentioned second pin group, that is, when an alarm signal needs to be transmitted to the mainboard, the alarm signal of the power supply component is transmitted to the mainboard through the S4 pin, when the AC-to-DC power-on is completed, the DCOK signal is transmitted to the mainboard through the S7 pin, when the power supply is in place, the PRSNT signal is transmitted to the mainboard through the S13 pin, and when the AC signal is powered on, the ACOK signal is transmitted to the mainboard through the S14 pin.

[0161] When two power supplies are connected to the first connector through the power supply board assembly to achieve connection with the mainboard, such as: the first power supply is connected to the first connector through the second power connector of the second connector of the power supply board assembly, and the second power supply is connected to the first connector through the first power connector of the second connector of the power supply board assembly.

[0162] At this time, the signal of the first power supply is transmitted through the first pin group of the first connector, and the signal of the second power supply is transmitted through the second pin group of the first connector. Among them, the second pin group includes: S4 pin, S7 pin, S13 pin and S14 pin, each pin in the second pin group is used to transmit the corresponding signal of the second power supply, and the first pin group includes: S9 pin, S10 pin, S11 pin and S12 pin, among which S9 pin, S11 pin and S12 pin are all multiplexed pins, and the address of the power connector is configured by only one S8 pin among the S8 pins and S9 pins, which can also achieve the purpose of distinguishing the two power supplies. S10 is a blank pin and can be used directly. S11 pin and S12 pin are used when the two power supplies are balanced. When there are two power supplies to power the motherboard, there is no mutual transmission. Therefore, the S11 pin and the S12 pin can be used in the current scenario. Therefore, the S9 pin, the S10 pin, the S11 pin and the S12 pin are used as the first pin group to transmit various signals of the first power supply, such as: when the first power supply has an alarm signal that needs to be transmitted to the mainboard, the alarm signal of the power supply component is transmitted to the mainboard through the S10 pin, when the AC-to-DC power-on of the first power supply is completed, the DCOK signal is transmitted to the mainboard through the S11 pin, when the first power supply is in place, the PRSNT signal is transmitted to the mainboard through the S9 pin, and when the AC signal of the first power supply is powered on, the ACOK signal is transmitted to the mainboard through the S12 pin.

[0163] The third pin group may be an S8 pin or an S9 pin, or other pin groups, which can identify whether the power supply component directly connected to the first connector is a power supply assembly or a power supply board assembly.

[0164] This embodiment discloses a power supply method, and its flow chart is as follows: Figure 8 As shown, including:

[0165] Step S81, directly connecting the first connector fixedly connected to the mainboard to the power supply component, so that the power supply component can supply power to at least a part of the circuit system of the mainboard;

[0166] Step S82, obtaining configuration information when the power supply component is directly connected to the first connector;

[0167] Step S83: If the configuration information of the power supply component satisfies the first configuration information, the control mainboard is connected to the power supply component through the first pin to obtain the first information, where the first configuration information is the configuration information of the first pin group of the first connector;

[0168] Step S84: If the configuration information of the power supply component satisfies the second configuration information, the control mainboard is connected to the power supply component through the second pin group to obtain second information, where the second configuration information is represented by the configuration information of the second pin group of the first connector.

[0169] The first configuration information is different from the second configuration information.

[0170] The power supply method disclosed in this embodiment is implemented based on the power supply system disclosed in the above embodiments.

[0171] The first connector is fixedly connected to the mainboard, and the power supply component is directly connected to the first connector, so that the power supply component supplies power to at least part of the circuit system on the mainboard through the first connector. In addition, the first connector has a first pin group for configuring the first information and a second pin group for configuring the second information, and the first pin group is different from the second pin group, so that when the power supply component is directly connected to the first connector, it can be connected to the mainboard through different pin groups.

[0172] When the power supply component is connected to the mainboard through the first connector, the power supply component directly supplies power to the mainboard through the first connector. At this time, at least part of the circuit system on the mainboard can determine whether there is a communication demand when there is power supply, and when there is a communication demand, it can communicate with the power supply component through some pins on the first connector.

[0173] The configuration information when the power supply component is directly connected to the first connector is obtained. The configuration information may be provided by the third pin group of the first connector. The third pin group is used to identify the power supply component directly connected to the first connector. Some pins of the third pin group are the same as some pins of the first pin group and / or the second pin group.

[0174] After obtaining the configuration information when the power supply component is directly connected to the first connector, the configuration information is analyzed to determine whether it satisfies the first information or the second information. If the configuration information satisfies the first information, it indicates that the power supply component is connected to the mainboard through the first pin group of the first connector. At this time, the mainboard can communicate with the power supply component through the first pin group of the first connector, that is, the power supply component can transmit communication signals to the mainboard through the first pin group of the first connector.

[0175] The communication signal transmitted by the power supply component to the mainboard through the first pin group can be specifically a sideband signal, such as: an alarm Alert signal of a sensor such as a register or temperature sensor, a DCOK signal for completion of AC-to-DC power-on, an ACOK signal for completion of AC signal power-on, a PRSNT signal for power in place, etc.

[0176] If it is determined that the configuration information satisfies the second information, it indicates that the power supply component is connected to the mainboard through the second pin group of the first connector. At this time, the mainboard can communicate with the power supply component through the second pin group of the first connector, that is, the power supply component can transmit communication signals to the mainboard through the second pin group of the first connector.

[0177] Correspondingly, the communication signal transmitted by the power supply component to the mainboard through the second pin group can be specifically a sideband signal, such as: an alarm Alert signal of a sensor such as a register or temperature sensor, a DCOK signal for completion of AC-to-DC power-on, an ACOK signal for completion of AC signal power-on, a PRSNT signal for power in place, etc.

[0178] Among them, the first information and the second information are different. The first information represents the configuration information of the first pin group of the first connector, and the second information represents the configuration information of the second pin group of the first connector. As long as it is determined that the configuration information of the power supply component satisfies the first information, it can be determined that the power supply component is directly connected to the first pin group of the first connector. Correspondingly, as long as it is determined that the configuration information of the power supply component satisfies the second information, it can be determined that the power supply component is directly connected to the second pin group of the first connector.

[0179] The first information may be related to the address of the first pin group, and the second information may be related to the address of the second pin group. As long as the configuration information of the power supply component is related to the address of the first pin group, it can be determined that the power supply component is directly connected to the first pin group of the first connector. If the configuration information of the power supply component is related to the address of the second pin group, it can be determined that the power supply component is directly connected to the second pin group of the first connector. Alternatively, the first information may also be related to other identification information of the first pin group, and the second information may be related to other identification information of the second pin group. Of course, the first information and the second information may also be other information, which is not specifically limited here.

[0180] by Figure 8 The first connector shown is used as an example for explanation, wherein the P series pins are pins on the first connector for current flow, i.e., for transmitting electrical energy, and the S series pins are pins on the first connector for transmitting sideband signals, i.e., transmitting control signals and / or detection signals.

[0181] When a power supply component is directly connected to the mainboard through the first connector, the connection between the power supply component and the mainboard is achieved through the second pin group of the first connector, wherein the second pin group may include: S4 pin, S7 pin, S13 pin and S14 pin, and each corresponding signal in the power supply component is transmitted to the mainboard through each pin in the above-mentioned second pin group, that is, when an alarm signal needs to be transmitted to the mainboard, the alarm signal of the power supply component is transmitted to the mainboard through the S4 pin, when the AC-to-DC power-on is completed, the DCOK signal is transmitted to the mainboard through the S7 pin, when the power supply is in place, the PRSNT signal is transmitted to the mainboard through the S13 pin, and when the AC signal is powered on, the ACOK signal is transmitted to the mainboard through the S14 pin.

[0182] When two power supplies are connected to the first connector through the power supply board assembly to achieve connection with the mainboard, such as: the first power supply is connected to the first connector through the second power connector of the second connector of the power supply board assembly, and the second power supply is connected to the first connector through the first power connector of the second connector of the power supply board assembly.

[0183] At this time, the signal of the first power supply is transmitted through the first pin group of the first connector, and the signal of the second power supply is transmitted through the second pin group of the first connector. Among them, the second pin group includes: S4 pin, S7 pin, S13 pin and S14 pin, each pin in the second pin group is used to transmit the corresponding signal of the second power supply, and the first pin group includes: S9 pin, S10 pin, S11 pin and S12 pin, among which S9 pin, S11 pin and S12 pin are all multiplexed pins, and the address of the power connector is configured by only one S8 pin among the S8 pins and S9 pins, which can also achieve the purpose of distinguishing the two power supplies. S10 is a blank pin and can be used directly. S11 pin and S12 pin are used when the two power supplies are balanced. When there are two power supplies to power the motherboard, there is no mutual transmission. Therefore, the S11 pin and the S12 pin can be used in the current scenario. Therefore, the S9 pin, the S10 pin, the S11 pin and the S12 pin are used as the first pin group to transmit various signals of the first power supply, such as: when the first power supply has an alarm signal that needs to be transmitted to the mainboard, the alarm signal of the power supply component is transmitted to the mainboard through the S10 pin, when the AC-to-DC power-on of the first power supply is completed, the DCOK signal is transmitted to the mainboard through the S11 pin, when the first power supply is in place, the PRSNT signal is transmitted to the mainboard through the S9 pin, and when the AC signal of the first power supply is powered on, the ACOK signal is transmitted to the mainboard through the S12 pin.

[0184] In addition, if only one power supply is connected to the first connector through the power supply board assembly, then whether to use the first pin group or the second pin group depends on whether the power supply is plugged into the first power connector or the second power connector of the second connector of the power supply board assembly. If the power supply is directly plugged into the first power connector, the signal of the power supply is transmitted to the mainboard through the first pin group on the first connector. If the power supply is directly plugged into the second power connector, the signal of the power supply is transmitted to the mainboard through the second pin group on the first connector.

[0185] Further, in the power supply method disclosed in this embodiment, if the configuration information of the power supply component satisfies the first information, the control mainboard is connected to the power supply component through the first pin group, including:

[0186] In response to the state of the first pin group of the first connector, it is determined that the mainboard is communicatively connected to the first power supply through the first pin group and the power supply board assembly; first information is obtained through the first pin group and the power supply board assembly; wherein the first information includes information of the power supply board assembly and first sub-information of the first power connector, and the first power connector is a power connector included in the second connector on the power supply board assembly that is connected to the power supply assembly.

[0187] The status of the first pin group of the first connector is monitored. If a specific pin in the first pin group is at a high level, it indicates that no power supply component is connected to the first pin group of the first connector; if the specific pin in the first pin group changes from a high level to a low level, it indicates that a power supply component is connected to the first pin group of the first connector.

[0188] In addition, since the first pin group of the first connector will be connected only when there are two power supplies and the two power supplies are connected to the mainboard through the power supply board assembly and the first connector, as long as it is determined that the first pin group of the first connector is connected, it can be determined that there are currently two power supplies connected to the mainboard through the power supply board assembly, and the first power supply is connected to the first pin group of the first connector through the power supply board assembly, and the second power supply is connected to the second pin group of the first connector through the power supply board assembly. At this time, information output by the first power supply can be obtained through the first pin group of the first connector, such as: the alarm Alert signal of sensors such as registers or temperature sensors, the DCOK signal of AC-to-DC power-on completion, the ACOK signal of AC signal power-on completion, the PRSNT signal of power in place, etc.; in addition, the first information can also be obtained through the first pin group of the first connector and the power supply board assembly.

[0189] At this time, the first information includes information of the power supply board assembly and first sub-information of the first power connector. The first power connector is a power connector included in the second connector on the power supply board assembly connected to the power supply assembly, and the first power connector is directly connected to the first power supply.

[0190] The information of the power board component may specifically be identification information of the power board component, such as address information, etc., and the first sub-information of the first power connector may specifically be identification information of the first power connector, such as address information, etc. The transmission path of the power and communication signals between the first power supply and the mainboard may be directly determined through the power board component information and the first sub-information of the first power connector.

[0191] by Figure 8 Taking this as an example, the level status of the S9 pin on the first connector can be monitored. As long as the level status of the S9 pin changes from a high level to a low level, it indicates that a power source is plugged into the first connector through the power supply board assembly. Because when the power source is directly plugged into the first connector, the S9 pin on the first connector will not change to a low level.

[0192] like Fig. 9 As shown, it is a schematic diagram of the power supply method disclosed in this embodiment, which includes two identification methods in the power supply method. The first is Fig. 9 For the left part, the level status of the S9 pin in the first connector can be monitored through the BMC or FPGA on the motherboard. The default level is high. If the level status of the S9 pin changes from high to low, it indicates that a power supply (PSU1) is plugged into the first connector through the power supply board assembly (PDB board); at this time, the FPGA accesses the input status of the power supply (PSU1) through the S9 pin, S10 pin, S11 pin and S12 pin. In addition, the address of the power supply (PSU1) is set at the power supply board assembly (PDB board), such as: A2 / B2.

[0193] The second is Fig. 9 On the right side, the BMC or FPGA on the motherboard monitors the level status of the S13 pin on the first connector, which is high by default. If the level status of the S13 pin changes from high to low, it indicates that a power supply (PSU) is connected. After that, it continues to determine whether the power supply (PSU) is connected to the motherboard through the power board assembly (PDB board) or directly connected to the motherboard. The BMC can read the device address information through the S1 pin or the S2 pin to determine whether the information of the device connected to the motherboard includes the information of the power board assembly (PDB board) (PDB FRU), if yes, the power supply PSU is connected to the mainboard through the power board component (PDB board) (PSU0 is already connected), at this time, the FPGA accesses the power information (PSU0) through the S4 pin, S7 pin, S13 pin and S14 pin, and at the same time, the address of the power supply (PSU0) is set at the power board component (PDB board) end, such as A0 / B0; if no, it can be determined that the power supply (PSU) is directly connected to the mainboard (PSUx is already connected), at this time, the FPGA accesses the power information (PSUx) through the S4 pin, S7 pin, S13 pin and S14 pin, ignores the input of the S9 pin, S10 pin, S11 pin and S12 pin, and at the same time, configures the address of the power supply (PSUx) through the S8 pin (S8 PU / PD) on the mainboard end and the S9 pin on the power supply end (PSU), such as: A4 / B4, or, A6 / B6.

[0194] Further, in the power supply method disclosed in this embodiment, if the configuration information of the power supply component satisfies the second information, the control mainboard is electrically connected to the power supply component through the second pin group, including:

[0195] In response to the state of the second pin group of the first connector, determine that the mainboard is in communication connection with the second power supply through the second pin group and the power supply board assembly; obtain second information through the second pin group and the power supply board assembly; wherein the second information includes information of the power supply board assembly and second sub-information of the second power connector, and the second power connector is a power connector included in the second connector on the power supply board assembly connected to the power supply assembly;

[0196] or,

[0197] In response to the state of the second pin group of the first connector, determine that the mainboard is communicatively connected to the target power supply through the second pin group and the target connector of the target power supply; obtain third sub-information through the second pin group and the target connector of the target power supply; wherein the third sub-information includes information of the target power supply.

[0198] The status of the second pin group of the first connector is monitored. If a specific pin in the second pin group is at a high level, it indicates that no power supply component is connected to the second pin group of the first connector; if the specific pin in the second pin group changes from a high level to a low level, it indicates that a power supply component is connected to the second pin group of the first connector.

[0199] When determining that a power supply component is connected to the second pin group, it is necessary to further determine whether the power supply component connected to the second pin group is a power supply board component or a power supply component. If it is a power supply board component, it indicates that a power supply component is connected to the first connector through the power supply board component and is connected to the mainboard. If it is a power supply component, it indicates that a power supply component is directly connected to the first connector to achieve connection with the mainboard. Whether the power supply component connected to the second pin group is a power supply board component or a power supply component can be determined by another specific pin on the first connector.

[0200] If it is determined through another specific pin on the first connector that a power supply component is connected to the first connector through the power supply board component, it is necessary to transmit information of the power supply component (such as the second power supply) through the second pin group on the first connector, such as: the alarm Alert signal of sensors such as registers or temperature sensors, the DCOK signal of AC-DC power-on completion, the ACOK signal of AC signal power-on completion, the power in place PRSNT signal, etc.; in addition, the second information can also be obtained through the second pin group of the first connector and the power supply board component. The second information includes not only the information of the power supply board component, but also the second sub-information of the second power connector. The second power connector is the power connector included in the second connector on the power supply board component connected to the power supply component.

[0201] The information of the power board component may specifically be identification information of the power board component, such as address information, etc. The second sub-information of the second power connector may specifically be identification information of the second power connector, such as address information, etc. The transmission path of the power and communication signals between the second power supply and the mainboard may be directly determined through the power board component information and the second sub-information of the second power connector.

[0202] If it is determined through another specific pin on the first connector that a target power supply is directly connected to the second pin group of the first connector, information about the target power supply needs to be transmitted through the second pin group on the first connector, such as: an alarm signal of a sensor such as a register or a temperature sensor, a DCOK signal indicating that power-on of the AC-to-DC converter is completed, an ACOK signal indicating that power-on of the AC signal is completed, a power-in-place PRSNT signal, etc.; in addition, third sub-information can also be obtained through the second pin group of the first connector, and the third sub-information includes information about the target power supply, such as: address information or identification information of the target power supply, etc.

[0203] by Figure 8 Taking the example of explanation, the level state of the S13 pin on the first connector can be monitored. As long as the level state of the S13 pin changes from a high level to a low level, it indicates that a power source is plugged into the first connector. At this time, the power supply component may be plugged into the first connector through a power supply board component, or the power supply component may be directly plugged into the first connector. In order to determine how the connection is made, it is necessary to further monitor the S1 pin or the S2 pin on the first connector. If it is determined that the information of the I2C device obtained by the S1 pin or the S2 pin on the first connector includes the information of the power supply board component, it indicates that the power supply component is plugged into the first connector through the power supply board component. If it is determined that the information obtained by the S1 pin and the S2 pin on the first connector does not include the information of the power supply board component, it indicates that the power supply component is plugged into the first connector through direct plugging.

[0204] The power supply method disclosed in this embodiment is to directly connect the power supply component with the first connector fixedly connected to the mainboard, so that the power supply component can supply power to at least part of the circuit system of the mainboard; obtain the configuration information when the power supply component is directly connected to the first connector; if the configuration information of the power supply component meets the first configuration information, control the mainboard to communicate and connect with the power supply component through the first pin to obtain the first information, and the first configuration information is represented as the configuration information of the first pin group of the first connector; if the configuration information of the power supply component meets the second configuration information, control the mainboard to communicate and connect with the power supply component through the second pin group to obtain the second information, and the second configuration information is represented as the configuration information of the second pin group of the first connector. In this scheme, when the power supply component is connected to the mainboard through the first connector, it can be determined based on the configuration information when the power supply component is directly connected to the first connector through which pin group of the first connector the power supply component is connected and communicated, so as to achieve precise control of the power supply component.
