The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0030] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0031] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0032] The present application embodiment provides an electronic device, referring to Figure 1 , Figure 4 and Figure 5 The electronic device includes a mainboard 2 and an adapter card module 1. The electronic device may be of various types, such as a server, a desktop computer, etc. It should be noted that in the embodiment of the present application, the type of the electronic device is not limited. In order to vividly illustrate the electronic device provided in the embodiment of the present application, the electronic device may be a server as an example.

[0033] Riser card, also known as expansion card or adapter card, usually has one or more PCIE slots, so that expansion cards with various functions, such as graphics card, sound card, etc., can be inserted into the slots of the riser card, thereby playing the role of transfer, so that the expansion capacity of the server can be increased when the server space is limited. For example, when the chassis size of the server is small, or other components need to be installed, the riser card can move the position of the expansion card to a more suitable position, thereby increasing the flexibility of the server. Since the attenuation of signal transmission in the cable is much smaller than the attenuation of the internal wiring of the printed circuit board (generally, the signal loss of the cable is only one tenth of the loss of the internal wiring of the circuit board), in order to reduce signal loss, a cable connection method is often used on the riser card. For example, in the previous riser card, two connectors are connected to the mainboard, the connector is connected to the cable, and the cable is connected to the circuit board of the riser card itself. That is, the signal is connected to the connector at the riser card end through a high-speed cable, and reaches the PCIE slot on the riser card after being routed inside the riser card, and then the gold finger of the PCIE card is connected to the PCIE slot. However, since the pins of the two connectors may be misaligned and the shapes may be inconsistent, routing is required inside the circuit board of the riser card, which will cause signal performance loss.

[0034] The present application embodiment provides a transfer card module 1, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5The adapter card module 1 includes a circuit board 11, a slot connector 12 and a first cable 13. The slot connector 12 is arranged on the circuit board 11, and has a first slot pin 121. The slot connector 12 is used to plug the expansion card; one end of the first cable 13 is connected to the first slot pin 121 in a one-to-one correspondence to form a first bonding pin 121J; the other end of the first cable 13 is used to connect to the mainboard 2 of the electronic device, so that the expansion card is connected to the first bonding pin 121J and is connected to the mainboard 2 through the first cable 13.

[0035] The adapter card module 1 in the embodiment of the present application, i.e., the riser card module, has a PCIE interface for connecting additional hardware devices, such as an expansion graphics card, a sound card, a redundant disk array card (Redundant Array of Independent Disks, RAID), etc., to the mainboard 2 of the electronic device to achieve functional expansion of the electronic device. The circuit board 11 in the embodiment of the present application can be understood as the circuit board 11 for connecting various components inside the electronic device, i.e., a printed circuit board or a printed circuit board (PCB), which the adapter card module 1 has. Correspondingly, the slot connector 12 is a PCIE slot provided on the circuit board 11 for plugging in an expansion card, where the expansion card can be an expansion graphics card, a sound card, a redundant disk array card, etc.

[0036] In the embodiment of the present application, the number of slot connectors 12 is not limited, and the slot connectors 12 arranged on the circuit board 11 can be one or more. The slot connector 12 can be a PCIE X16 slot connector, a PCIE X8 slot connector, a PCIE X4 slot connector, etc., to respectively insert PCIE expansion cards of corresponding specifications. Taking the PCIE X16 slot connector as an example, it has multiple pins for power supply and data transmission, which can be mainly used to plug in graphics cards and RAID array cards, etc., and can be used for backward compatibility with X1, X4, and X8 level devices. Here, the first slot pin 121 of the slot connector 12 in the embodiment of the present application can be understood as a pin for data transmission, and the slot connector 12 also has a power supply pin for power supply connection.

[0037] In the embodiment of the present application, one end of the first cable 13 is connected to the first slot pin 121 in a one-to-one correspondence to form a first bonding pin 121J. Here, the first bonding pin 121J can be formed by welding one end of the first cable 13 and the first slot pin 121 together, or by conductive bonding together, such as, referring to Figure 4 , Figure 4The connection portion between the first cable 13 and the first slot pin 121 in the middle rectangular dotted area is formed as a first joint pin 121J. The way in which the other end of the first cable 13 is connected to the motherboard 2 of the electronic device is not limited. The other end of the first cable 13 may be connected through a connector provided on the motherboard 2, or the other end of the first cable 13 may be welded and connected to the motherboard 2, so as to communicate with the CPU of the server through the internal wiring of the motherboard 2. In this way, when an expansion card is inserted into the slot of the slot connector 12, signal data can be sequentially transmitted through the CPU of the server, the motherboard 2 of the server, the connection end of the first cable 13 and the motherboard 2, the connection between the first cable 13 and the first slot pin 121, and the gold finger of the expansion card to realize signal transmission between the motherboard 2 of the server and the expansion card. Compared with connecting the first cable 13 to the circuit board 11, routing the signal through the inside of the circuit board 11, and then transmitting it to the expansion card through the slot connector 12 connected to the circuit board 11, in the embodiment of the present application, since one end of the first cable 13 is directly connected to the first slot pin 121, it is equivalent to allowing the transmission signal to avoid the circuit board 11 (that is, it is equivalent to routing 0 in the circuit board 11), so that the transmission signal can be transmitted to the expansion card through the first slot pin 121 of the slot connector 12 without routing the signal through the inside of the circuit board 11, thereby avoiding the signal loss caused by the signal routing through the inside of the circuit board 11.

[0038] Among them, the circuit board 11 may have through holes corresponding to the first slot pins 121 one by one, and the first slot pins 121 may pass through the through holes one by one and be welded and fixed on the circuit board 11, and then one end of the first cable 13 may be conductively bonded to the first slot pin 121, so as to realize the connection between the first slot pin 121 and the first cable 13. Here, the connection between the first cable 13 and the first slot pin 121 may be located on the side of the circuit board 11 facing the slot connector 12, or on the side of the circuit board 11 away from the slot connector 12; or the first cable 13 and the first slot pin 121 may be first welded or conductively bonded together, and then connected together to the same side of the circuit board 11.

[0039] It should be noted that, since one end of the first cable 13 is directly connected to the first slot pin 121 in the embodiment of the present application, the signal transmission between the expansion card and the mainboard 2 can be performed without passing through the internal wiring of the circuit board 11. Therefore, the first slot pin 121 of the slot connector 12 may not be connected to the circuit board 11. Figure 3 and Figure 8 , the body of the circuit board 11 may be hollowed out in the area of ​​the circuit board 11 corresponding to the first slot pin 121 to reduce the material cost of the circuit board 11 .

[0040] For example, refer to Figure 2 , Figure 3 , Figure 6 and Figure 8 The circuit board 11 has a first side and a second side opposite to each other along the first direction. Considering that the body of the circuit board 11 has a first board surface and a second board surface opposite to each other along the thickness direction thereof, here, for the sake of convenience, the first board surface can be understood as the first side of the circuit board 11, and the first board surface can be used as a side for connecting electronic components (such as arranging a slot connector 12 on the first board surface to plug in electronic components such as an expansion graphics card and a sound card), and correspondingly, the second side is the second board surface of the circuit board 11. The slot connector 12 is fixed on the first side of the circuit board 11; the slot connector 12 has a first part 12a, which is a part of the slot connector 12 corresponding to the first slot pin 121; the circuit board 11 has a notch area 111, and along the first direction, the notch area 111 is opposite to the first part 12a, so that the circuit board 11 avoids the first part 12a; wherein the first direction is the thickness direction of the circuit board 11. Here, the design of the notch area 111 on the circuit board 11 can, on the one hand, enable the notch area 111 to bear part of the installation space for the slot connector 12, thereby saving the electronic device space occupied by the entire adapter card module 1; on the other hand, it can reduce the material used for the circuit board 11. The specific shape and size of the notch area 111 are not limited, for example, the shape of the notch area 111 can be a regular square, oval, etc., or an irregular shape.

[0041] Further, refer to Figure 2 , Figure 3 and Figure 8 The notch area 111 is formed at an opening on one side of the circuit board 11 along the third direction, and the notch area 111 is a rectangular area; along the second direction, the length of the slot connector 12 is greater than the length of the notch area 111; along the third direction, the width of the slot connector 12 is less than the width of the notch area 111; wherein the second direction is the length direction of the circuit board 11, and the third direction is the width direction of the circuit board 11. With such a design, the manufacturing cost of the circuit board 11 can be reduced as much as possible.

[0042] In some embodiments, reference Figure 1 , Figure 4 , Figure 8 and Fig. 9, the end of the first cable 13 connected to the first slot pin 121 and the first portion 12a are integrally formed by the injection molding part 3 to form the first area D1 of the slot connector 12; wherein at least a portion of the first area D1 is filled in the gap area 111. The end of the first cable 13 connected to the first slot pin 121 and the first portion 12a can be integrally formed by the injection molding process. Here, the end of the first cable 13 connected to the first slot pin 121 is also the first bonding pin 121J, and the first bonding pin 121J and the first portion 12a of the slot connector 12 can be injection molded to form the first area D1 of the slot connector 12. Specifically, for example, the first cable 13 and the first slot pin 121 may be bonded together at one end to form the first bonding pin 121J, and then the first bonding pin 121J connected together may be loaded into the injection mold, and then the resin of the injection mold 3 may be injected to make the molten resin material and the first bonding pin 121J solidify, that is, it can be understood that the first slot pin 121 in the first part 12a of the slot connector 12 and the first cable 13 are integrally formed by the injection mold 3. Alternatively, the end of the first cable 13 connected to the first slot pin 121 and the first part 12a of the slot connector 12 (including the first slot pin 121 and the body of the first part 12a of the slot connector 12 except the first slot pin 121) are integrally formed by the injection mold 3 to form the first area D1 of the slot connector 12, that is, the first area D1 of the entire slot connector 12 is integrally formed by injection molding. In this way, the reliability and integrity of the connection between the first cable 13 and the first slot pin 121 can be improved.

[0043] Among them, at least part of the first area D1 of the slot connector 12 is filled in the gap area 111, which can be understood as, for example, referring to Figure 1 and Figure 3 When the notch area 111 is square, part of the side wall of the first area D1 of the slot connector 12 abuts against the side wall of the edge around the notch area 111 of the circuit board 11. In this way, the entire adapter card module 1 can be made more compact.

[0044] A power supply interface is often reserved on the riser card so that power can be taken from the power supply module of the server through the connector, and then power is supplied to the expansion card in the PCIE slot on the riser card. For example, the PCIE slot has a power supply pin, and the server is connected to the circuit board 11 of the riser card through a power cable. The power supply pin of the PCIE slot connected to the circuit board 11 is supplied through the internal wiring of the circuit board 11, and then the gold finger of the expansion card supplies power to the expansion card. That is, the slot connector 12 not only needs to have pins for transmitting signals but also needs to have power supply pins for powering the expansion card. Taking the PCIEX16 slot connector 12 with a maximum power consumption of 75W as an example, the power supply pins related to power supply include +12V pin, +3.3V pin, GND pin, etc.

[0045] For example, refer to Figure 2 , Figure 7 and Figure 8 , the adapter card module 1 also includes a second cable 14, one end of the second cable 14 is connected to the circuit board 11, and the other end of the second cable 14 is used to connect to the mainboard 2, and the second cable 14 is used to provide the first voltage provided by the mainboard 2 to the circuit board 11. Specifically, one end of the second cable 14 can be connected to the mainboard 2 through a connector, and the other end of the second cable 14 can be welded and connected to the circuit board 11. For example, one end of the second cable 14 has a pin, and the circuit board 11 has a via corresponding to the pin, and the pin passes through the via and is welded and connected to the circuit board 11. In this way, the power supply can be first supplied to the circuit board 11 through the connection end between the mainboard 2 and the second cable 14, and then through the connection end between the second cable 14 and the circuit board 11. After that, it can also be supplied to the expansion card plugged in the slot through the power supply pin of the slot connector 12 connected to the circuit board 11 after the internal wiring of the circuit board 11. Here, for example, when the expansion card is an expansion graphics card with higher power consumption, the first voltage can be 12V to meet the power consumption requirements of the expansion graphics card.

[0046] Reference Fig.10 The circuit board 11 is provided with a voltage conversion module 6, which is used to convert the first voltage provided by the motherboard 2 into a second voltage, wherein the second voltage is less than the first voltage. Here, the first voltage may be 12V, and correspondingly, the second voltage may be 3.3V. In this way, it can be used to meet the power consumption requirements of ordinary graphics cards with lower power consumption.

[0047] Further, refer to Fig.10, a circuit protection unit 4 is also provided on the circuit board 11, and the circuit protection unit 4 is connected between the input end of the first voltage and the output end of the second voltage, and is used to disconnect the circuit when the circuit current of the circuit board 11 is overloaded. Here, the circuit protection unit 4 can be an electronic fuse, and the circuit protection unit 4 is used to accurately detect the current and voltage by measuring the voltage and converting it into a digital signal through an analog-to-digital converter, and when the current exceeds the preset limit, the circuit can be cut off through a field effect transistor.

[0048] In some embodiments, reference Figure 3 , Figure 8 and Fig.10 An auxiliary power supply interface 7 is also provided on the circuit board 11. The auxiliary power supply interface 7 can be used to connect a power supply module. Here, the power supply module can be a power supply provided on the riser card, or an additional power supply provided on the server. When the mainboard 2 of the server loses power, the expansion card plugged into the riser card can be powered by connecting a power cord to the auxiliary power supply interface 7, so that the slots on the riser card can work independently without relying on the power supply input of other slots, thereby improving the reliability and flexibility of the adapter card module 1.

[0049] For example, refer to Figure 6 to Figure 10 , the slot connector 12 is provided with a first threaded hole 123, and the circuit board 11 is provided with a second threaded hole 112. The fastener 5 is sequentially passed through the first threaded hole 123 and the second threaded hole 112 to fix the slot connector 12 on the circuit board 11. Here, the fastener 5 can be a screw that is threadedly adapted to the first threaded hole 123 and the second threaded hole 112. Specifically, the first area D1 of the slot connector 12 corresponds to the notch area 111 of the circuit board 11, and the first area D1 of the slot connector 12 passes through the notch area 111. After the second slot pin 122 at the second area D2 of the slot connector 12 is connected to the circuit board 11, the second area D2 of the slot connector 12 is attached to one side of the circuit board 11 along the thickness direction. The first threaded holes 123 are opened at both opposite ends of the slot connector 12 along the second direction, and each corresponds to the two second threaded holes 112 on the circuit board 11 one by one, and is fastened and connected by the fastener 5. This method is simple and easy to operate, and it is convenient to disassemble and assemble the circuit board 11.

[0050] In some embodiments, reference Figure 4 , Figure 5 and Fig.10, the slot connector 12 has a second slot pin 122, and the portion of the slot connector 12 corresponding to the second slot pin 122 is the second portion 12b of the slot connector 12, which can also be called the second area D2 of the slot connector 12; the projection of the second portion 12b in the first direction falls on the circuit board 11, and the second slot pin 122 is connected to the circuit protection unit 4 and the interface of the second voltage through the internal wiring of the circuit board 11, and is used to power the expansion card plugged into the slot connector 12. Among them, the second slot pin 122 of the slot connector 12 can be understood as a pin mainly used for power supply, and correspondingly, the first slot pin 121 of the slot connector 12 can be understood as a pin used for data signal transmission. For example, slot connector 2 takes the PCIE X16 slot connector as an example. The total length of the slot is 89 mm and there are 164 pins. The shorter slot has 22 pins and is mainly used for power supply. Here, the shorter slot can be understood as the second part 12b of the slot connector 12, and the 22 pins of the shorter slot can be understood as the second slot pins 122 of the slot connector 12; the longer slot has 142 pins and is mainly used for data transmission. It has the high bandwidth brought by 16 channels. Here, the longer slot can be understood as the first part 12a of the slot connector 12, and the 142 pins of the longer slot can be understood as the first slot pins 121 of the slot connector 12. The second slot pin 122 opposite to the second part 12b of the slot connector 12 is connected to the circuit board 11, and then connected to the circuit protection unit 4 and the second voltage interface through the internal wiring of the circuit board 11, so that the current provided by the mainboard 2 is sequentially connected through the connection end of the second cable 14 and the mainboard 2, the second cable 14, the connection end of the second cable 14 and the circuit board 11, the internal wiring of the circuit board 11, the second slot pin 122 of the slot connector 12 connected on the circuit board 11, and the gold finger of the expansion card to power the expansion card.

[0051] Specifically, refer to Figure 1 to Figure 5 , Figure 7 and Fig.10, one end of the second cable 14 is connected to the mainboard 2 of the server, and is used to supply power to the expansion card through the mainboard 2, such as providing a 12V voltage to the other end of the second cable 14 through the mainboard 2. Here, the connection between one end of the second cable 14 and the mainboard 2 can be connected through a connector; the other end of the second cable 14 can be provided with a pin, and the pin of the end is inserted into the via hole on the circuit board 11 and then welded to the circuit board 11. The adapter card module 1 also includes a third cable 15 and a sideband cable 16. The third cable 15 can be a 3.3V power supply cable. One end of the third cable 15 can be connected to the mainboard 2 through a connector, and the other end can be welded to the circuit board 11, so as to provide a 3.3V voltage to the connection end of the second cable 14 and the circuit board 11, so as to power the expansion card with low power consumption; one end of the sideband cable 16 is connected to the mainboard 2 of the server, and the other end can be welded to the circuit board 11. Here, the sideband cable 16 is used to transmit a sideband signal, such as an interrupt signal INTX. For example, when the server mainboard 2 provides a 12V voltage to the circuit board 11 through the second cable 14, the internal wiring of the circuit board 11 can first pass through the circuit protection unit 4, continue through the internal wiring of the circuit board 11, pass through the connection end of the third cable 15 and the circuit board 11, and the connection end of the sideband cable 16 and the circuit board 11, and then reach the second slot pin 122 of the slot connector 12 through the internal wiring of the circuit board 11, and finally supply the voltage to the expansion card through the gold finger of the expansion card plugged into the slot connector 12. Here, the 12V voltage can be used to provide expansion cards with high power consumption requirements, and the 3.3V voltage can be used to provide expansion cards with normal power consumption requirements.

[0052] With the above design, the slot connector 12 of each slot of the Riser card can work independently without relying on the input of other slots, which makes the application of the adapter card module 1 more flexible; at the same time, since the auxiliary power interface 7 and the circuit protection unit 4 are both arranged on the circuit board 11 of the adapter card module 1, rather than on the main board 2 of the server, there is no need to redesign the main board 2, which can help reduce the production design cost of the main board 2; in addition, the first cable 13 is directly connected to the first slot pin 121 of the slot connector 12, thereby avoiding the internal routing generated by the connection with the circuit board 11, and thus causing signal integrity problems, so that while reducing signal loss, it is possible to reduce the size of the main board 2 and reduce the material of the main board 2, thereby further reducing the cost of the main board 2.
