[0018] Specifically, referring to FIGS. 1-7, the embodiment of the 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 on the output side of the server power supply. The circuit board connection structure comprises a first circuit board 10 and at least two second circuit boards 20. One side of the first circuit board 10 is connected to the power transmission line inside the server power supply. The at least two second circuit boards 20 are configured to be connected to loads. The at least two second circuit boards are selectively mounted on the other side of the first circuit board 10. Each second circuit board 20 is configured with an output member on the side away from the first circuit board 10, and the output member is used to electrically connect to the load. Any two output members of the at least two second circuit boards 20 are different.

[0019] In some embodiments, the second circuit board 20 is provided in at least two, and the at least two second circuit boards 20 are alternatively mounted to the first circuit board 10. Since the output members of the at least two second circuit boards 20 are different, the second circuit board 20 with the output member of the corresponding type can be selected based on the use scenario of the server power supply, and the second circuit board 20 is assembled to the first circuit board 10. In this way, the compatibility of the server power supply can be improved by selecting the type of output member, and the output mode of each server power supply is diversified.

[0020] It can be understood that the output members of any two of the at least two second circuit boards 20 are different, which can be that the product types of the output members of any two of the at least two second circuit boards 20 are different, the product categories of the output members of any two of the at least two second circuit boards 20 are different, the product materials of the output members of any two of the at least two second circuit boards 20 are different, the output voltages that can be carried by the output members of any two of the at least two second circuit boards 20 are different, or the sizes of the output members of any two of the at least two second circuit boards 20 are different.

[0021] The circuit board connection structure provided in the embodiment is particularly suitable for a server power supply, and based on different types of loads, different second circuit boards 20 can be selected to be assembled to the first circuit board 10, so as to adapt to the connectors of different types of loads.

[0022] In some embodiments, the output member includes at least one of the connector 210 and the wire 220. It can be understood that the output member can only be the connector 210, or the output member can only be the wire 220, or the output member is a combination of the connector 210 and the wire 220. In this way, the server power supply can be compatible with the connector 210 output, the wire 220 output, and the connector 210 and the wire 220 output at the same time.

[0023] As shown in FIG. 3, the output member on the second circuit board 20 is a connector 210, at this time, the use scenario of the load input end being a connector 210 can be adapted. As shown in FIG. 4, the output member on the second circuit board 20 is a wire 220, at this time, the use scenario of the load input end being a wire 220 can be adapted. As shown in FIG. 5, the output member on the second circuit board 20 is a connector 210 and a wire 220, at this time, the use scenario of the load input end being a connector 210 and a wire 220 can be adapted.

[0024] In some embodiments, the first circuit board 10 is configured with a first electrical connection part, the second circuit board 20 is configured with a second electrical connection part, and the first electrical connection part is electrically connected with the second electrical connection part. In this way, signal transmission and electrical transmission between the first circuit board 10 and the second circuit board 20 are realized.

[0025] As shown in FIGS. 2-5, in some embodiments, one of the first and second electrical connection portions is a pin 30, the other of the first and second electrical connection portions is a socket 40, and the pin 30 is inserted into the socket 40. Based on the insertion of the pin 30 into the socket 40, signal transmission between the first circuit board 10 and the second circuit board 20 is achieved.

[0026] For example, the pin 30 can be provided on a side of the first circuit board 10 facing the second circuit board 20 as the first electrical connection portion, and the socket 40 can be provided on the second circuit board 20 as the second electrical connection portion. The pin 30 is inserted into the socket 40 to achieve signal transmission between the first circuit board 10 and the second circuit board 20.

[0027] For example, the socket 40 can be provided on the first circuit board 10 as the first electrical connection portion, and the pin 30 can be provided on a side of the second circuit board 20 facing the first circuit board 10 as the second electrical connection portion. The pin 30 is inserted into the socket 40 to achieve signal transmission between the first circuit board 10 and the second circuit board 20.

[0028] For example, the pin 30 can be provided on a side of the first circuit board 10 facing the second circuit board 20 as the first electrical connection portion, and the socket 40 can be provided on the second circuit board 20 as the second electrical connection portion. The pin 30 is inserted into the socket 40 to achieve signal transmission between the first circuit board 10 and the second circuit board 20.

[0029] As shown in FIGS. 2-5, in some embodiments, one of the first and second electrical connection portions is a copper bridge 50 having a first connecting hole 510 formed thereon, the other of the first and second electrical connection portions is a second connecting hole 60, the copper bridge 50 abuts against the first circuit board 10 or the second circuit board 20, and the first connecting hole 510 and the second connecting hole 60 are connected by a fastener. The first electrical connection portion and the second electrical connection portion are connected by inserting the fastener through the first connecting hole 510 and the second connecting hole 60, and electrical connection between the two is achieved based on the electrical conductivity of the fastener itself. Thus, the first circuit board 10 and the second circuit board 20 can be electrically connected.

[0030] It can be understood that the copper bridge 50 is an electrical device for achieving signal connection and electrical connection between circuit boards of different layers. The copper bridge 50 is usually made of a conductive metal such as copper, and is not limited to being made of copper. The copper bridge 50 can be provided in a columnar shape, a bridge shape, etc. For example, the copper bridge 50 can be provided as a conductive column, one end of the conductive column is electrically connected to the first circuit board 10, the other end of the conductive column abuts against the second circuit board 20, and the second connecting hole 60 of the second circuit board 20 is connected by a fastener and electrical connection is achieved. For example, the copper bridge 50 can be provided as a U-shaped piece, one side of the U-shaped piece is electrically connected to the first circuit board 10, the other side of the U-shaped piece abuts against the second circuit board 20, and the second connecting hole 60 of the second circuit board 20 is connected by a fastener and electrical connection is achieved.

[0031] The first connecting hole 510 is arranged along the height direction of the copper bridge 50. When the copper bridge 50 is a conductive column, the first connecting 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 piece, the first connecting hole 510 is arranged on one of the ears of the U-shaped piece.

[0032] 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. At this time, the fastener can play a conductive role to realize the electrical connection between the two. Of course, the fastener can also be an insulating fastener. At this time, the copper bridge 50 directly abuts against the first circuit board 10 or the second circuit board 20 to realize the electrical connection between the two.

[0033] For example, the copper bridge 50 can be configured as the first electrical connection part on the side of the first circuit board 10 facing the second circuit board 20, and the second connecting hole 60 can be configured as the second electrical connection part on the second circuit board 20. The side of the copper bridge 50 away from the first circuit board 10 abuts against the second circuit board 20, and the first connecting hole 510 and the second connecting hole 60 are aligned. The fastener is sequentially arranged in the second connecting hole 60 and the first connecting hole 510 to realize reliable connection between the first circuit board 10 and the second circuit board 20, and to form electrical connection between the first circuit board 10 and the second circuit board 20.

[0034] For example, the second connecting hole 60 can be configured as the first electrical connection part on the first circuit board 10, and the copper bridge 50 can be configured as the second electrical connection part on the side of the second circuit board 20 facing the first circuit board 10. The side of the copper bridge 50 away from the second circuit board 20 abuts against the first circuit board 10, and the first connecting hole 510 and the second connecting hole 60 are aligned. The fastener is sequentially arranged in the second connecting hole 60 and the first connecting hole 510 to realize reliable connection between the first circuit board 10 and the second circuit board 20, and to form electrical connection between the first circuit board 10 and the second circuit board 20.

[0035] In some embodiments, the number of copper bridges 50 is at least two, and the working voltages of the at least two copper bridges 50 are different. It can be understood that based on the number of copper bridges 50, the same number of second connecting holes 60 can be correspondingly arranged. Based on the arrangement of the at least two copper bridges 50 and the at least two second connecting holes 60, the connection between the first circuit board 10 and the second circuit board 20 can be more stable and reliable, and the first circuit board 10 and the second circuit board 20 have multiple electrically conductive circuits therebetween, ensuring the stability and redundancy of the electrical connection.

[0036] The working voltages of the at least two copper bridges 50 are different, so that the copper bridges 50 can be adapted to the use requirements of 3.3V, 5V, 12V and GND (Ground) respectively.

[0037] As shown in FIGS. 2-5, in some embodiments, one of the first circuit board 10 and the second circuit board 20 is configured with a connecting column 70 extending towards the other, the connecting column 70 is configured with a first mounting hole 710, and the other of the first circuit board 10 and the second circuit board 20 is configured with a second mounting hole 80, wherein the connecting part 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 a fastener.

[0038] It can be understood that by penetrating the fastener in the first mounting hole 710 and the second mounting hole 80, the mechanical connection of the first circuit board 10 and the second circuit board 20 can be achieved.

[0039] In the embodiments of the present application, the fastener can be a screw, and the inner surface of the first mounting hole 710, the second mounting hole 80, the first connecting hole 510 and the second connecting hole 60 is provided with an inner thread matched with the screw, so that the fastener can be assembled on the first circuit board 10 and the second circuit board 20.

[0040] For example, the connecting column 70 is configured on the side of the first circuit board 10 facing the second circuit board 20, and the second mounting hole 80 is configured on the second circuit board 20. When the connecting column 70 abuts against the second circuit board 20, the first mounting hole 710 on the connecting column 70 is aligned with the second mounting hole 80 on the second circuit board 20. The fastener is sequentially penetrated in the second mounting hole 80 and the first mounting hole 710 to achieve reliable and stable connection between the first circuit board 10 and the second circuit board 20.

[0041] For example, the connecting column 70 is configured on the side of the second circuit board 20 facing the first circuit board 10, and the 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. The fastener is sequentially penetrated in the second mounting hole 80 and the first mounting hole 710 to achieve reliable and stable connection between the first circuit board 10 and the second circuit board 20.

[0042] In some embodiments, the end of the connecting column 70 can also be provided with an integrally formed clamping portion, the radius of the clamping portion being smaller than the radius of the connecting column 70, and the radius of the clamping portion being the same as the radius of the second mounting hole 80. When the first circuit board 10 and the second circuit board 20 are connected by overlapping, the clamping portion can be clamped in the second mounting hole 80. In this way, the positioning of the first circuit board 10 and the second circuit board 20 is achieved. Then, the fastener is passed through the second mounting hole 80 and the first mounting hole 710 to achieve locking.

[0043] As shown in FIG. 2, the first circuit board 10 in the embodiment of the application is configured with a pin 30, a copper bridge 50, and a connecting column 70 on the side facing the second circuit board 20. In the orientation in FIG. 2, one pin 30 can be provided on the first circuit board 10, which can be located at the upper position of the first circuit board 10. Of course, the position and number of the pins 30 on the first circuit board 10 can be reasonably arranged based on the position and number of the sockets 40 on the second circuit board 20. Four copper bridges 50 can be provided on the first circuit board 10. Two of the copper bridges 50 are provided in a column shape, and the other two copper bridges 50 are provided in a U-shaped piece. The first connecting hole 510 is configured on the column-shaped copper bridge 50 and the U-shaped copper bridge 50, so that the electrical connection between the copper bridge 50 and the second circuit board 20 is achieved by cooperating the fastener with the first connecting hole 510. In this way, the electrical signal transmission between the first circuit board 10 and the second circuit board 20 is achieved. Four connecting columns 70 can be provided on the first circuit board 10, and the four connecting columns 70 can be distributed in a rectangular shape. Based on the four connecting columns 70 provided on the first circuit board 10, four second mounting holes 80 are correspondingly provided on the second circuit board 20, and the fastener is sequentially fastened to the first mounting hole 710 of the four connecting columns 70 and the second mounting hole 80, so as to achieve the connection between the first circuit board 10 and the second circuit board 20.
