[0035] For details, please refer to Figures 1 to 7 , an embodiment of the present application provides a circuit board connection structure. The circuit board connection structure is applied to a server power supply. The circuit board connection structure is arranged at the output side of the server power supply. The circuit board connection structure includes a first circuit board 10 and at least two second circuit boards 20. Among them, one side of the first circuit board 10 is connected to the power transmission line inside the server power supply. At least two second circuit boards 20 are configured to connect to a load. At least two second circuit boards are selectively installed on the other side of the first circuit board 10, and each second circuit board 20 is configured with an output component on a side away from the first circuit board 10, and the output component is used to electrically connect to the load. Among them, any two output components of the at least two second circuit boards 20 are different.

[0036] In some embodiments, at least two second circuit boards 20 are provided, so that at least two second circuit boards 20 are selectively mounted on the first circuit board 10. Since the output components of the at least two second circuit boards 20 are different, a second circuit board 20 with an output component of a corresponding model can be selected based on the usage scenario of the server power supply, and the second circuit board 20 can be assembled on the first circuit board 10. Thus, the compatibility of the server power supply can be improved by selecting the type of output component, so that the output mode of each server power supply can be diversified.

[0037] It can be understood that any two output components in at least two second circuit boards 20 are different, which may be: the product models of any two output components in at least two second circuit boards 20 are different, the product types of any two output components in at least two second circuit boards 20 are different, the product materials of any two output components in at least two second circuit boards 20 are different, the output voltages that any two output components in at least two second circuit boards 20 can carry are different, and the sizes of any two output components in at least two second circuit boards 20 are different.

[0038] The circuit board connection structure provided in this embodiment is particularly suitable for server power supplies. Based on different types of loads, different second circuit boards 20 can be selected to be assembled on the first circuit board 10 to adapt to connectors of different types of loads.

[0039] In some embodiments, the output component includes at least one of a connector 210 and a wire 220. It is understandable that the output component may be only the connector 210, or the output component may be only the wire 220, or the output component is a combination of the connector 210 and the wire 220. Thus, the server power supply can be compatible with the output of the connector 210, the output of the wire 220, and the output of the connector 210 and the wire 220 at the same time.

[0040] like Figure 3 The output component on the second circuit board 20 is a schematic diagram of a structure in which the connector 210 is used. In this case, the load input terminal can be adapted to the use scenario of the connector 210. Figure 4 The figure shows a schematic diagram of a structure in which the output member on the second circuit board 20 is a wire 220. In this case, the use scenario in which the load input end is a wire 220 can be adapted. Figure 5 The diagram shows a structure in which the output components on the second circuit board 20 are a connector 210 and a wire 220 . At this time, the load input end can be adapted to the usage scenario in which the connector 210 and the wire 220 are used.

[0041] In some embodiments, a first electrical connection portion is configured on the first circuit board 10, and a second electrical connection portion is configured on the second circuit board 20, and the first electrical connection portion is electrically connected to the second electrical connection portion, thereby achieving signal transmission and electrical transmission between the first circuit board 10 and the second circuit board 20.

[0042] like Figures 2 to 5 As shown, in some embodiments, one of the first electrical connection portion and the second electrical connection portion is a pin header 30, and the other of the first electrical connection portion and the second electrical connection portion is a socket header 40, and the pin header 30 is inserted into the jack of the socket header 40. Based on the insertion of the pin header 30 and the socket header 40, signal transmission between the first circuit board 10 and the second circuit board 20 is achieved.

[0043] For example, a pin header 30 may be provided on the side of the first circuit board 10 facing the second circuit board 20 as a first electrical connection portion, and a socket 40 may be provided on the second circuit board 20 as a second electrical connection portion. The pin header 30 is inserted into the jack of the socket 40 to achieve signal transmission between the first circuit board 10 and the second circuit board 20.

[0044] For example, a row seat 40 can be provided on the first circuit board 10 as a first electrical connection portion, and a row pin 30 can be provided on the side of the second circuit board 20 facing the first circuit board 10 as a second electrical connection portion. The row pin 30 is inserted into the jack of the row seat 40 to achieve signal transmission between the first circuit board 10 and the second circuit board 20.

[0045] The pin header 30 may be a double-row pin header 30 , and the socket 40 may be a double-row socket socket 40 .

[0046] like Figures 2 to 5 As shown, in some embodiments, one of the first electrical connection part and the second electrical connection part is a copper bridge 50, and a first connection hole 510 is configured on the copper bridge 50. The other of the first electrical connection part and the second electrical connection part is a second connection hole 60. The copper bridge 50 abuts against the first circuit board 10 or the second circuit board 20, and the first connection hole 510 and the second connection hole 60 are connected by a fastener. By inserting the fastener into the first connection hole 510 and the second connection hole 60, the first electrical connection part and the second electrical connection are connected, and based on the conductive performance of the fastener itself, the electrical connection between the two is achieved. In this way, the first circuit board 10 and the second circuit board 20 can be electrically connected.

[0047] It can be understood that the copper bridge 50 is an electrical device for realizing signal connection and electrical connection between circuit boards of different layers. The copper bridge 50 is usually made of conductive metal such as copper, and is not limited to copper materials. Among them, the copper bridge 50 can be set to a columnar shape, a bridge shape, etc. For example, the copper bridge 50 can be set to a conductive column, one end of the conductive column is electrically connected to the first circuit board 10, and the other end of the conductive column abuts the second circuit board 20, and is connected to the second connection hole 60 of the second circuit board 20 through a fastener, and an electrical connection is achieved. For example, the copper bridge 50 can be set to a U-shaped member, one side of the U-shaped member is electrically connected to the first circuit board 10, and the other side of the U-shaped member abuts the second circuit board 20, and is connected to the second connection hole 60 of the second circuit board 20 through a fastener, and an electrical connection is achieved.

[0048] The first connection holes 510 are arranged along the height direction of the copper bridge 50. When the copper bridge 50 is a conductive column, the first connection hole 510 extends along the height direction of the conductive column at the center of the conductive column. When the copper bridge 50 is a U-shaped member, the first connection hole 510 is disposed on one of the ear plates of the U-shaped member.

[0049] When the first circuit board 10 and the second circuit board 20 are connected by the copper bridge 50 and the fastener, the fastener made of conductive material can be used to connect the first circuit board 10 and the second circuit board 20. In this case, the fastener can play a conductive role to achieve electrical connection between the two. Of course, the fastener can also be an insulating fastener. In this case, the copper bridge 50 directly abuts against the first circuit board 10 or the second circuit board 20 to achieve electrical connection between the two.

[0050] For example, a copper bridge 50 can be constructed as a first electrical connection portion on a side of the first circuit board 10 facing the second circuit board 20, and a second connection hole 60 can be constructed on the second circuit board 20 as a second electrical connection portion. The side of the copper bridge 50 away from the first circuit board 10 abuts against the second circuit board 20, and the first connection hole 510 and the second connection hole 60 are aligned, and the fastener is sequentially inserted into the second connection hole 60 and the first connection hole 510, so as to realize a reliable connection between the first circuit board 10 and the second circuit board 20, and to form an electrical connection between the first circuit board 10 and the second circuit board 20.

[0051] For example, a second connection hole 60 can be constructed on the first circuit board 10 as the first electrical connection portion, and a copper bridge 50 can be constructed on the side of the second circuit board 20 facing the first circuit board 10 as the second electrical connection portion. The side of the copper bridge 50 away from the second circuit board 20 abuts against the first circuit board 10, and the first connection hole 510 and the second connection hole 60 are aligned. The fastener is sequentially inserted into the second connection hole 60 and the first connection hole 510, so as to realize a reliable connection between the first circuit board 10 and the second circuit board 20, and to form an electrical connection between the first circuit board 10 and the second circuit board 20.

[0052] In some embodiments, the number of copper bridges 50 is set to at least two, wherein the operating voltages of at least two copper bridges 50 are different. It is understandable that, based on the number of copper bridges 50, the same number of second connection holes 60 can be correspondingly set. Based on the arrangement of at least two copper bridges 50 and at least two second connection holes 60, the connection between the first circuit board 10 and the second circuit board 20 can be made more stable and reliable, and multiple phase-conducting circuits can be provided between the first circuit board 10 and the second circuit board 20, thereby ensuring the stability and redundancy of the electrical connection.

[0053] Based on the different working voltages of at least two copper bridges 50 , the copper bridge 50 can respectively adapt to the use requirements of 3.3V (volt), 5V, 12V and GND (Ground).

[0054] like Figures 2 to 5 As shown, in some embodiments, one of the first circuit board 10 and the second circuit board 20 is constructed with a connecting column 70 extending toward the other, and a first mounting hole 710 is constructed on the connecting column 70, and the other of the first circuit board 10 and the second circuit board 20 is constructed with a second mounting hole 80, wherein the connecting portion 910 abuts against the first circuit board 10 or the second circuit board 20, and the first mounting hole 710 and the second mounting hole 80 are connected by fasteners.

[0055] It can be understood that by inserting the fasteners through the first mounting hole 710 and the second mounting hole 80 , the mechanical connection between the first circuit board 10 and the second circuit board 20 can be achieved.

[0056] Among them, the fasteners in the embodiments of the present application can all be screws. Correspondingly, the inner surfaces of the first mounting hole 710, the second mounting hole 80, the first connecting hole 510 and the second connecting hole 60 are all provided with internal threads compatible with the screws, so that the fasteners can be assembled on the first circuit board 10 and the second circuit board 20.

[0057] For example, a connection column 70 is configured on the side of the first circuit board 10 facing the second circuit board 20, and a second mounting hole 80 is configured on the second circuit board 20. When the connection column 70 abuts against the second circuit board 20, the first mounting hole 710 on the connection column 70 is aligned with the second mounting hole 80 on the second circuit board 20. Fasteners are sequentially inserted through the second mounting hole 80 and the first mounting hole 710 to achieve a reliable and stable connection between the first circuit board 10 and the second circuit board 20.

[0058] For example, a connecting column 70 is configured on the side of the second circuit board 20 facing the first circuit board 10, and a second mounting hole 80 is configured on the first circuit board 10. When the connecting column 70 abuts against the first circuit board 10, the first mounting hole 710 on the connecting column 70 is aligned with the second mounting hole 80 on the first circuit board 10. Fasteners are sequentially inserted through the second mounting hole 80 and the first mounting hole 710 to achieve a reliable and stable connection between the first circuit board 10 and the second circuit board 20.

[0059] In some embodiments, the end of the connecting column 70 may also be provided with an integrally formed clamping portion, the radius of which is smaller than the radius of the connecting column 70, and the radius of which is the same as the radius of the second mounting hole 80. When the first circuit board 10 and the second circuit board 20 are overlapped and connected, the clamping portion may be clamped in the second mounting hole 80. Thus, the first circuit board 10 and the second circuit board 20 are pre-positioned. Then, fasteners are inserted through the second mounting hole 80 and the first mounting hole 710 to achieve locking.

[0060] like Figure 2 As shown, the first circuit board 10 in the embodiment of the present application is configured with a pin header 30, a copper bridge 50 and a connecting column 70 on the side facing the second circuit board 20. Figure 2In terms of the orientation in the middle, a pin row 30 may be provided on the first circuit board 10, and the pin row 30 may be provided at a position slightly above the first circuit board 10. Of course, the position and number of the pin row 30 on the first circuit board 10 may also be reasonably set based on the position and number of the row seat 40 on the second circuit board 20. Four copper bridges 50 may be provided on the first circuit board 10. Two of the copper bridges 50 are arranged in a columnar shape, and the other two copper bridges 50 are arranged in a U-shaped piece. A first connecting hole 510 is constructed on both the copper bridge 50 in a columnar shape and the copper bridge 50 in a U-shaped piece, so as to realize the electrical connection between the copper bridge 50 and the second circuit board 20 through the first connecting hole 510 in conjunction with the fastener. In this way, the transmission of electrical signals between the first circuit board 10 and the second circuit board 20 is realized. Four connecting columns 70 may be provided on the first circuit board 10, and the four connecting columns 70 may be distributed in a rectangular shape. Based on the fact that four connecting pillars 70 are arranged on the first circuit board 10, four second mounting holes 80 are correspondingly arranged on the second circuit board 20. Fasteners are used to sequentially fasten the first mounting holes 710 and the second mounting holes 80 of the four connecting pillars 70 to achieve the connection between the first circuit board 10 and the second circuit board 20.

[0061] Please continue reading Figure 2 In the embodiment of the present application, the first circuit board 10 is configured with a plurality of electrical connectors on a side facing away from the second circuit board 20, and the plurality of electrical connectors are used to connect the power transmission line inside the server power supply, so that the server power supply supplies power to the outside through the first circuit board 10 and the second circuit board 20. The type and quantity of the electrical connectors configured on the first circuit board 10 can be specifically selected based on the type and quantity of the power transmission line inside the server power supply, and the embodiment of the present application does not limit it.

[0062] like Figure 6 and Figure 7 As shown, the embodiment of the present application also provides a server power supply, including a housing 90 and the circuit board connection structure in the above embodiment. The first circuit board 10 and the second circuit board 20 are both arranged in the housing 90, and the first circuit board 10 is electrically connected to the power transmission line in the housing 90.

[0063] In some embodiments, at least two second circuit boards 20 are provided, so that at least two second circuit boards 20 are selectively mounted on the first circuit board 10. Since the output components of the at least two second circuit boards 20 are different, a second circuit board 20 with an output component of a corresponding model can be selected based on the usage scenario of the server power supply, and the second circuit board 20 can be assembled on the first circuit board 10. Thus, the compatibility of the server power supply can be improved by selecting the type of output component, so that the output mode of each server power supply can be diversified.

[0064] like Figure 6As shown, the housing 90 may be a square housing structure, and the first circuit board 10 and the second circuit board 20 are also set to be square. When the housing 90 is set to other shapes, the shapes of the first circuit board 10 and the second circuit board 20 can be changed accordingly.

[0065] The first circuit board 10 and the second circuit board 20 are arranged in the housing 90 , and the housing 90 can be used to protect the first circuit board 10 and the second circuit board 20 , so as to prevent the first circuit board 10 and the second circuit board 20 from being placed outside and causing potential safety hazards.

[0066] In some embodiments, the housing 90 is configured with a connecting portion 910 bent inwardly, and a fastening hole 920 is configured on the connecting portion 910. The fastening hole 920 is connected to the first mounting hole 710 of the first circuit board 10 and the second mounting hole 80 of the second circuit board 20 through fasteners.

[0067] Among them, the shell 90 can be set in a direction, and each side of the shell 90 can be constructed with a connecting portion 910 bent inwardly, so as to fix the first circuit board 10 and the second circuit board 20 in multiple directions, ensuring the reliable fixation of the first circuit board 10 and the second circuit board 20.

[0068] By fixing the first circuit board 10 and the second circuit board 20 to the connection portion 910 of the housing 90 through fasteners, the first circuit board 10 and the second circuit board 20 can be stably and reliably fixed on the housing 90. At the same time, there is no need to use a back cover to seal and fix the first circuit board 10 and the second circuit board 20. As a result, the structure of the server power supply is optimized, the back cover design is eliminated, and the production cost is reduced.

[0069] The removal of the back cover can also facilitate the assembly of the server power supply, optimize the assembly process of the server power supply, and improve the production efficiency of the server power supply.

[0070] In the embodiment of the present application, the first circuit board 10 and the second circuit board 20 are fixed in the housing 90 by fasteners, so the first circuit board 10 and the second circuit board 20 can be installed after being formed. Whether the connector 210 is used as the output part of the second circuit board 20 or the wire 220 is used as the output part of the second circuit board 20, the output part can be soldered to the second circuit board 20 by using a tin furnace, thereby improving the working efficiency and reducing the labor cost.

[0071] In some embodiments, heat dissipation holes may be configured on the housing 90 to facilitate heat dissipation of the first circuit board 10 , the second circuit board 20 and the electrical components in the housing 90 .

[0072] An embodiment of the present application also provides a server power supply system, including the server power supply in the aforementioned embodiment.

[0073] In some embodiments, at least two second circuit boards 20 are provided, so that at least two second circuit boards 20 are selectively mounted on the first circuit board 10. Since any two output components of the at least two second circuit boards 20 are different, a second circuit board 20 with an output component of a corresponding model can be selected based on the usage scenario of the server power supply, and the second circuit board 20 can be assembled on the first circuit board 10. Thus, the compatibility of the server power supply can be improved by selecting the type of output component, so that the output mode of each server power supply can be diversified.

[0074] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0075] The above is a detailed introduction to a circuit board connection structure, a server power supply and a server power supply system provided in the embodiments of the present application.

The description of the above embodiments is only used to help understand the technical solutions and core ideas of the present application.
