Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
When the equipment to be powered, such as an expansion card conforming to PCIe specifications, is connected with the server and needs the server to supply power to the equipment, because the specification model or line definition of the connector on the server motherboard is not uniform, when the expansion card is in power supply connection with different servers, different power supply cables are needed, and the problem of poor compatibility of power supply connection between the expansion card and the servers is caused.
For this purpose, the present application proposes a patch card, a device and a method for supplying power, wherein the patch card 1 for supplying power comprises: the circuit comprises a first power pin 11, a connecting component 12 and a substrate 13, wherein the first power pin 11 is detachably connected with a first standard slot on a main board, the connecting component 12 is electrically connected with the first power pin 11, and the substrate 13 is respectively connected with the first power pin 11 and the connecting component 12.

Because the adapter card 1 is matched with the first standard slot, the connection between the adapter card 1 and the first standard slot replaces the direct connection between the power supply equipment and the main board by the power supply cable 2 in the prior art, so that the problem that the connection compatibility between the power supply equipment 3 and the main board is poor due to the fact that different power supply cables 2 are needed when the power supply equipment 3 is connected with different main boards in the prior art is solved.
In addition, the device to be powered 3 includes devices such as an expansion card that need to acquire a power signal, where the first standard slot is located on a motherboard, and the motherboard is located on a server that is used to power the device to be powered 3, where in this application, for convenience of description, the device to be powered 3 is taken as the expansion card, and the device to be powered 3 is taken as the server, which is used to power the device to be powered 3, which is described in this application is explained in detail below.
As shown in fig. 1, in one embodiment, there is provided a transit card for supplying power, the transit card 1 including:
the first power supply pin 11 is used for acquiring a power supply signal when the first power supply pin 11 is detachably connected with a first standard slot on a main board for supplying power;

a substrate 13, wherein the substrate 13 is connected with the first power pin 11 and the connection component 12 respectively.
It should be noted that, in view of improving the function expandability, a plurality of first standard slots are provided on a general server motherboard, and each first standard slot is electrically connected to a power supply unit inside the server. When the expansion card is detachably connected with the second standard slot, and the consumption power required by the expansion card exceeds the power which can be provided by the expansion card, the server is required to provide additional power for the expansion card so that the expansion card can be used continuously.
At this time, the adapter card 1 is detachably connected to the first standard slot of the server motherboard, and the output end of the adapter card 1 is electrically connected to the power input end of the expansion card through the power supply cable 2. The first power pin 11 obtains a power signal provided in the server through the first standard slot, and outputs the power signal to the connection component 12 through a circuit on the substrate 13; the connection component 12 outputs the power signal to the expansion card, so that the server provides additional power for the expansion card, and normal use of the expansion card is ensured.
Because the motherboard is provided with a plurality of first standard slots, and in all the first standard slots, idle slots are generally unused. The connection between the adapter card 1 and the device 3 to be powered is performed by detachably connecting the adapter card 1 with the first standard slot, and the adapter card 1 is matched with the first standard slot. Through the connection of adapter card 1 with first standard slot has replaced among the prior art directly to utilize power supply cable 2 will power supply equipment is connected with the mainboard, thereby has improved among the prior art when waiting to supply power equipment 3 and different mainboards to be connected, needs different power supply cable 2, leads to wait to supply power equipment 3 and the poor problem of connection compatibility between the mainboard.
In other embodiments, the first power pins 11 with different specifications may be provided, and it should be noted that, the different specifications of the first power pins 11 refer to obtaining power signals with different voltage values, for example, the first power pin 11 with one specification may obtain a power signal with a voltage value of 3.3V, the first power pin 11 with one specification may obtain a power signal with a voltage value of 12V, and so on. For convenience of description, the possibility of all embodiments is not described herein, and should be considered as the scope of the present description, as long as there is no contradiction and the requirement of acquiring a power signal and outputting is satisfied.
As shown in fig. 3, as a preferred implementation of the above embodiment, the connection assembly 12 includes:
and two or more first connectors 121 connected in parallel, wherein one end of each first connector 121 is electrically connected with the first power pin 11, and the other end of each first connector 121 is used for outputting the power signal.
As described with reference to fig. 4, in this embodiment, the first connector 121 includes a power connector, and since the power input end on the motherboard also generally uses the power connector to transmit the power signal, two connection ports for connecting the riser card 1 and the power supply cable 2 of the expansion card standby power supply device 3 may be set according to the interface of the power connector, so as to ensure connection compatibility between the riser card 1 and the expansion card. When in use, the power supply signal is output to the equipment to be powered 3 through a power supply connector; when the adapter card 1 includes two or more first connectors 121, i.e. power connectors, each power connector receives the power signals obtained by the first power pins 11, at this time, the output ends of each power connector are connected with the expansion cards respectively, so that the server can provide power signals for the corresponding number of expansion cards respectively, thereby meeting more scene requirements and improving the scene applicability of the adapter card 1.
As a specific implementation manner of the foregoing embodiment, the adapter card 1 is matched with the shape and size of the high-speed serial computer expansion bus standard card, and the first power pin 11 and the first standard slot pass through the high-speed serial computer expansion bus standard protocol.
It should be noted that, the standard of the expansion bus of the high-speed serial computer is PCIe, and because in the specification of PCIe, the standard of the power connector of the expansion card is defined, and the standard of the power connector of the server motherboard is not defined, because the manufacturers for producing the server motherboard are different, the power connectors on the motherboard are different. Therefore, in practical application, when the expansion card is detachably connected to different server mainboards and the server is used for supplying power to the expansion card, the power supply cable 2 cannot be suitable for different servers, so that the problem of poor compatibility is caused. Therefore, in this embodiment, the riser card 1 is set to conform to the PCIe specification, and since the first standard slot on the server motherboard also conforms to the PCIe specification, the connection between the riser card 1 and the first standard slot passes through the PCIe protocol. Because the power supply cable 2 for connecting the adapter card 1 and the expansion card can be arranged according to the interface of the power supply connector, the power supply cable 2 is replaced by the adapter card 1 and the power supply cable 2 in the prior art, so that the power supply of the server to the expansion card is realized, and the problem of poor compatibility caused by the power supply cable 2 can be improved when the expansion card is connected with different server mainboards.
In addition, the function of the adapter card 1 is single, and the transmission of the power signal is realized here, but the transmission of the high-speed signal is not involved, so that the adapter card 1 can be produced by adopting low-cost materials, thereby reducing the cost. In terms of appearance, the adapter card 1 may be configured to conform to the PCIe standard, or may be configured to be smaller than the PCIe standard, so as to further save costs. Compared with the prior art, the power supply connector on the main board of the server needs to be customized to different power supply cables 2, and the adapter card 1 is arranged, so that the cost is saved to a certain extent.
As another implementation manner of the foregoing embodiment, the adapter card 1 includes two or more substrates 13, one ends of two adjacent substrates 13 are connected in an insulating manner, and the other ends of two adjacent substrates 13 are respectively connected to two first power pins 11.
It should be noted that, the two first power pins 11 of the adapter card 1 are detachably connected with two adjacent first standard slots on the motherboard, and because the two substrates 13 all include the connection assembly 12 and the circuit connecting the first power pins 11 and the first standard slots, by adopting the adapter card 1 in this embodiment, transmission of power signals to two expansion cards can be realized simultaneously, and connection stability of the adapter card 1 and the first standard slots is improved.
In another embodiment, as shown in fig. 5, there is provided an apparatus for supplying power, the apparatus including the adapter card for supplying power as described in the previous embodiment, the apparatus further including:
the power supply cable is characterized by comprising a power supply cable, wherein one end of the power supply cable is electrically connected with the output end of the adapter card, and the other end of the power supply cable is used for outputting a power supply signal acquired by the adapter card to equipment to be powered when the other end of the power supply cable is electrically connected with the equipment to be powered;
the preprocessing unit is used for acquiring the consumed power and the first available power of the equipment to be powered and comparing the consumed power with the value of the first available power, wherein the first available power comprises the power output by a second power supply pin of the equipment to be powered when the equipment to be powered is detachably connected with a second standard slot of a main board;
and the control unit is used for communicating the line between the adapter card and the equipment to be powered under the condition that the consumed power is larger than the first available power so as to enable the equipment to be powered to receive the power supply signal through the power supply cable.
It should be noted that, the adaptor card included in the device has been described in detail in the foregoing, and reference is made to the foregoing description for the relevant description, which is not repeated herein. The preprocessing unit and the control unit may be embedded in the adapter card, or may be separate devices or apparatuses, so long as the above principle requirements can be met, and the preprocessing unit and the control unit are not limited herein.
When the device is used for realizing that the server supplies power to the expansion card, the transfer card is detachably connected with the first standard slot of the server main board, and the output end of the transfer card is electrically connected with the power input end of the expansion card through the power supply cable. The preprocessing unit is used for acquiring the consumed power and the first available power of the expansion card, comparing the consumed power with the value of the first available power and sending the comparison result to the control unit. The power consumption is the power consumption of the expansion card, namely the power supply power required by the expansion card in normal operation, and the first available power comprises the power output by the second power supply pin of the expansion card when the expansion card is detachably connected with the second standard slot of the main board. The control unit is used for communicating the circuit between the transfer card and the expansion card when the received comparison result is that the consumed power is larger than the first available power, namely the power which can be provided by the expansion card cannot meet the power consumption of the expansion card, so that the expansion card receives the power supply signal obtained from the server by the transfer card through the power supply cable, and the normal operation of the expansion card is ensured. Through the control unit, can automatic intercommunication the switching card with return circuit between the expansion card only needs the user to carry out the aforesaid with this device and arrange the connection in advance, does not need the manual operation of user, convenient to use, and reduces user's work load.
When the device for supplying power supplies power to the equipment to be supplied with power, the expansion card is provided with a plurality of first standard slots, and in all the first standard slots, idle slots are generally unused. The adapter card is detachably connected with the first standard slot, then the adapter card is connected with the equipment to be powered, and the adapter card is matched with the first standard slot. Through the adapter card with the connection of first standard slot has replaced among the prior art directly to utilize power supply cable will power supply equipment is connected with the mainboard, thereby has improved among the prior art when waiting to supply power equipment is connected with different mainboards, needs different power supply cable, leads to wait to supply power equipment and the poor problem of connection compatibility between the mainboard.
For example, in one of the application scenarios, because the standard of the power connector of the expansion card is defined in the PCIe specification, the standard of the power connector of the server motherboard is not defined, and because the manufacturers that produce the server motherboard are different, the power connectors on the motherboard are different. Therefore, in practical application, when the expansion card is detachably connected to different server mainboards and the server is used for supplying power to the expansion card, the problem that the power supply cable cannot be suitable for different servers and poor compatibility is caused can occur.
Therefore, the transit card can be set to conform to the specification of PCIe, and since the first standard slot on the server motherboard also conforms to the specification of PCIe, connection between the transit card and the first standard slot passes through the protocol of PCIe. Because the power supply cable for connecting the adapter card and the expansion card can be arranged according to the interface of the power connector, the power supply cable is replaced by the adapter card and the power supply cable in the prior art, and the power supply of the server to the expansion card is realized, so that the problem of poor compatibility caused by the power supply cable can be solved when the expansion card is connected with different server mainboards.

It should be noted that, when the power signal obtained by one switch card is insufficient to provide power for the expansion card, a plurality of switch cards may be stacked and used to meet the requirement of providing power for the expansion card. When a plurality of adapter cards are used, the adapter cards are detachably connected in a first standard slot on the main board respectively; the transmission direction of the power supply signal is as follows: from the first power supply pin to the connecting component, sequentially connecting adapter cards plugged on a main board in series according to the transmission direction of the power supply signals, so as to realize superposition of the power supply signals; and the output ends of the connecting components are respectively connected with the expansion card.
