Description

Technical Field

[0001] The present application relates to the field of server power supply technology, and in particular to a server motherboard and a server. Background Art

[0002] A server is a high-performance computer composed of hardware such as a processor, memory, hard disk, and power supply. Since servers need to manage resources and provide computing or application services to other clients (such as personal computers, smartphones, and ATM terminals), their performance requirements in terms of computing power, stability, reliability, security, scalability, and manageability are particularly important.

[0003] In related technologies, a server uses a power supply module (i.e., server power supply) to power the server's motherboard to maintain long-term stable operation of the server. Usually, the power supply module converts 230V AC power into 12V low-voltage DC power to power the server's internal motherboard. The server's motherboard uses a DC-DC module to convert the 12V low-voltage DC power into a DC voltage suitable for the requirements of various components inside the server.

[0004] However, due to the complex internal circuits of the server motherboard, a layered power supply is required, resulting in a motherboard that is too thick, causing severe heat generation on the server motherboard and affecting the operating performance of the electronic components on it. At the same time, because the internal power supply lines of the server motherboard are too long, a large voltage loss is generated from the power supply module to the various components in the server. Summary of the Invention

[0042] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0043] In the related art, the server uses a power supply module 6 (i.e., a server power supply) to power the server's mainboard to maintain long-term stable operation of the server. Usually, the power supply module 6 converts 230V AC power into 12V low-voltage DC power to power the mainboard inside the server. The mainboard of the server uses a DC-DC module to convert the 12V low-voltage DC power into a DC voltage suitable for the requirements of various components inside the server.

[0044] However, due to the complex internal circuits of the server motherboard, a layered power supply is required, which makes the motherboard too thick, causing serious heat generation on the server motherboard and affecting the operating performance of the electronic components thereon; at the same time, because the internal power supply lines of the server motherboard are too long, a large voltage loss is generated from the power supply module 6 to the various components in the server.

[0045] In order to reduce the heat generated by the server motherboard and the problem of large voltage loss from the power supply module 6 to various components in the server, the present application provides a server motherboard and a server.

[0046] The following combination Figures 1 to 6 , describing the embodiments of the present application.

[0047] According to an embodiment of the present application, on the one hand, a server motherboard is provided, such as Figure 1 and Figure 2 As shown, it includes a main board body 1 and a main power supply line 2, and the specific solution is as follows.

[0048] like Figure 1 and Figure 2 As shown, the mainboard body 1 is a PCB circuit board or a circuit board made of other materials; a plurality of first auxiliary power supply circuits 102 and a plurality of first electronic components 101 are provided on the mainboard body 1, and the first ends of the plurality of first auxiliary power supply circuits 102 are electrically connected to the plurality of first electronic components 101 respectively.

[0049] Specifically, the plurality of first electronic components 101 may be a processor, a memory, a hard disk, a graphics card, a RAID card (RAID, Redundant Array of Independent Disks), a network card, a fan, and part of other components on a motherboard.

[0050] The plurality of first auxiliary power supply lines 102 are usually embedded in the main board body 1 .

[0051] like Figure 1 As shown, the main power supply circuit 2 is provided on the main board body 1. Specifically, the main power supply circuit 2 can be provided inside the main board body 1, such as Figure 2 As shown, it can also be set outside the main board body 1; the main power supply line 2 extends along the circumference of the main board body 1, the main power supply line 2 is electrically connected to the power supply module 6, and the second ends of multiple first auxiliary power supply lines 102 are all electrically connected to the main power supply line 2.

[0052] In any one of the first auxiliary power supply lines 102 , the connection portion between the main power supply line 2 and the second end of the first auxiliary power supply line 102 is close to the first electronic component 101 to which the first end of the first auxiliary power supply line 102 is connected.

[0053] It needs to be explained that the above-mentioned "main power supply line 2 extends along the circumference of the main board body 1" means that the main power supply line 2 is arranged in a ring on the main board body 1, wherein the ring can be a ring that is connected from end to end, or it can be an incomplete ring that is not connected from end to end; as for the shape of the ring, it can be any shape, such as a square ring, a circular ring, an elliptical ring, a polygonal ring, etc., which can be set according to actual needs, and is preferably a square ring, because the main board body 1 is usually rectangular.

[0054] It should also be noted that the main power supply line 2 extends along the circumference of the main board body 1 and can form a complete ring or an incomplete ring, so that the projection of the main power supply line 2 on the main board body 1 in a direction perpendicular to the main board body 1 can encircle a portion of the first electronic component 101 (that is, a portion of the first electronic component 101 is located on the periphery of the main power supply line 2, and a portion of the first electronic component 101 is located in the inner circle of the main power supply line 2), or it can encircle the entire first electronic component 101.

[0055] During specific use, the power supply module 6 of the server is electrically connected to the main power supply line 2 to supply power thereto; the main power supply line 2 supplies power to each first electronic component 101 through each first auxiliary power supply line 102 .

[0056] In this embodiment, if Figure 1 and Figure 2As shown, the main power supply line 2 extends along the circumference of the main board body 1, and the main board body 1 is provided with a plurality of first sub-power supply lines 102 for connecting with the plurality of first electronic elements 101 respectively, and in any one of the first sub-power supply lines 102, the part where the main power supply line 2 is connected with the second end of the first sub-power supply line 102 is close to the first electronic element 101 connected with the first end of the first sub-power supply line 102, so that each first electronic element 101 can directly take power from the nearest part of the main power supply line 2, and the main power supply line 2 can be a line with small resistance, such as a copper wire or a silver wire with large diameter, to reduce the voltage drop loss from the server power supply module 6 to each first electronic element 101.

[0057] Meanwhile, since each first electronic element 101 adopts the scheme of taking power from the nearest part, the first sub-power supply line 102 for supplying power to each first electronic element 101 avoids overlapping and crossing, thereby reducing or avoiding the layered design of the power supply line, so that the thickness of the main board body 1 is reduced.

[0058] Secondly, the main power supply line 2 extends along the circumference of the main board body 1, and each first electronic element 101 adopts the scheme of taking power from the nearest part, which can simplify the length of the power supply line in the main board and reduce the resistance of the power supply line, thereby reducing the heat of the main board body 1 and reducing the influence on the operating performance of the electronic elements on the main board body 1.

[0059] In one embodiment, as shown in Figure 1 and Figure 3 The server mainboard further comprises at least one bridge power supply line 3, specifically, the bridge power supply line 3 can be a conductive body with small resistance such as a copper wire or a silver wire; the bridge power supply line 3 is arranged on the main board body 1, and the bridge power supply line 3 is electrically connected with the main power supply line 2; as shown in Figure 1 in the first direction X, the projection of the bridge power supply line 3 on the plane where the main board body 1 is located is located on the main board body 1, and the first direction X is perpendicular to the main board body 1.

[0060] As shown in Figure 3 The main board body 1 is further provided with at least one second sub-power supply line 104 and at least one second electronic element 103, the first end of the second sub-power supply line 104 is electrically connected with the second electronic element 103, and the second end of the second sub-power supply line 104 is electrically connected with the bridge power supply line 3.

[0061] Specifically, the plurality of second electronic elements 103 can be part of a processor, a memory, a hard disk, a graphics card, a RAID card (RAID, Redundant Array of Independent Disks), a network card, a fan, and other elements on the motherboard; preferably, the second electronic element 103 is an electronic element located in the middle region of the motherboard body 1, such as a processor, a memory stick, a graphics card, etc.

[0062] Among any one of the second sub-power supply lines 104, the part where the bridge power supply line 3 is connected to the second end of the second sub-power supply line 104 is close, and the first end of the second sub-power supply line 104 is connected to the second electronic element 103.

[0063] It should be noted that the above-mentioned "along the first direction X, the projection of the bridge power supply line 3 on the plane where the motherboard body 1 is located, is located on the motherboard body 1, and the first direction X is perpendicular to the motherboard body 1" means that the bridge power supply line 3 extends in the motherboard body 1, and the extension direction can be a straight line, or a curved line, a broken line, etc.; The number can be one, or multiple, and the specific number can be selected and set according to actual needs; The purpose is to avoid the overlap of the second sub-power supply lines 104 of the multiple second electronic elements 103 and the main power supply line 2 due to the large number of second electronic elements 103.

[0064] In the specific use process, as shown in Figure 1 and Figure 3 , if multiple second electronic elements 103 are arranged in a certain region of the motherboard body 1, and the power supply lines are arranged to be electrically connected to the main power supply line 2, due to the large number of second sub-power supply lines 104 that need to be arranged, the area of the motherboard body 1 is limited, and the power supply lines of the second electronic elements 103 need to be arranged in layers. By setting the bridge line and reasonably arranging the multiple second electronic elements 103 on both sides of the bridge power supply line 3, the overlap of the second sub-power supply lines 104 of the second electronic elements 103 can be avoided, and the processor and the memory can be conveniently powered nearby.

[0065] In this embodiment, as shown in Figure 1 and Figure 3 , by setting the bridge power supply line 3 on the motherboard body 1, and electrically connecting it to the main power supply line 2, and its projection along the first direction X is located in the motherboard body 1, so that the bridge power supply line 3 can realize the extension of the main power supply line 2 in the region of the motherboard body 1, so as to facilitate the nearby power supply of the densely arranged second electronic elements 103, and further simplify the power supply line of the server motherboard, reduce the thickness and heat of the server motherboard, etc.

[0066] In one embodiment, the distance between at least a portion of the second electronic components 103 and the bridge power supply line 3 is less than the distance between the second electronic components 103 and the main power supply line 2, that is, at least a portion of the second electronic components 103 is far away from the main power supply line 2, and then draws power from the main power supply line 2. On the one hand, the resistance of the second auxiliary power supply line 104 is large, which will cause voltage drop loss. Secondly, when the second auxiliary power supply line 104 extends to the position of the main power supply line 2, there is a risk of crossing with other first auxiliary power supply lines 102 or having limited space, and overlapping settings are required.

[0067] In specific usage, if the second electronic component 103 is a processor and memory on a server motherboard, the processor and memory are far away from the main power supply line 2, and there are many power supply lines for the processor and memory. If the power supply line is arranged to be electrically connected to the main power supply line 2, since there are many lines that need to be arranged, it may be overlapped and layered with the power supply lines or other signal circuits of other electronic components. By setting a bridge line, the power supply signal of the main power supply line 2 is directly led to the vicinity of the processor and memory, making it convenient for the processor and memory to obtain power nearby.

[0068] In this embodiment, by electrically connecting the second electronic component 103 on the mainboard that is far away from the main power supply line 2 with the bridge power supply line 3 extending around it, the second electronic component 103 that is far away from the main power supply line 2 can be powered nearby, which can further simplify the power supply line of the server mainboard, reduce the thickness and heat generation of the server mainboard, etc.

[0069] In one embodiment, Figure 4 As shown, the ends of the main power supply line 2 are not connected, that is, the power supply line does not form a complete ring; the middle part of the main power supply line 2 is electrically connected to the power supply module 6, and the two ends of the main power supply line 2 extend in opposite directions along the circumference of the mainboard body 1.

[0070] In the specific use process, such as Figure 4 As shown, the power supply module 6 is connected to the middle of the active electrical circuit, so that the power supply module 6 can simultaneously supply power to both ends of the main power supply circuit 2 to respectively supply power to the first electronic component 101 and the second electronic component 103 located on both sides of the power supply module 6.

[0071] In this embodiment, Figure 4 As shown, since the ends of the main power supply line 2 are not connected, the length of the main power supply line 2 can be reduced; and the two ends of the main power supply line 2 are respectively along the axial direction of the mainboard body 1 and extend in opposite directions, which can provide power to the first electronic component 101 and the second electronic component 103 located on both sides of the power supply module 6 respectively, so as to shorten the power supply length and reduce the voltage drop loss.

[0072] In one embodiment,Figure 2 As shown, the main power supply line 2 is spaced apart from the main board body 1; Figure 3 As shown, the bridge power supply line 3 is spaced apart from the main board body 1; that is, a certain distance is set between the main power supply line 2 and the bridge power supply line 3 and the main board body 1 to separate the main power supply line 2 and the preceding power supply line from the main board module.

[0073] Specifically, the interval between the main power supply line 2 and the main board body 1 is 1mm to 10mm, specifically any one of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10mm; it can also be other values, which can be set according to actual needs.

[0074] In the specific use process, such as Figure 2 and Figure 3 As shown, the main power supply line 2 and the bridge power supply line 3 are spaced apart from the mainboard body 1, which can prevent the heat generated by the main power supply line 2 and the bridge power supply line 3 from being transferred to the mainboard body 1, thereby increasing the temperature of the mainboard body 1; secondly, the cooling airflow of the server can be used to cool the main power supply line 2 and the bridge power supply line 3, thereby improving the heat dissipation efficiency of the server.

[0075] In one embodiment, Figure 2 As shown, a plurality of first voltage conversion modules 201 are provided on the main power supply line 2. Specifically, the first voltage conversion module 201 is a collection module formed by resistors, capacitors, diodes, etc., and its input end can be connected to the main power supply line 2 by welding; the plurality of first voltage conversion modules 201 are located between the main power supply line 2 and the mainboard body 1, and the plurality of first voltage conversion modules 201 are electrically connected to the main power supply line 2, and a first plug slot is provided on the first voltage conversion module 201.

[0076] like Figure 2 As shown, multiple first auxiliary power supply lines 102 are located inside the main board body 1, and a first power-taking copper column 1021 is provided at the second end of the first auxiliary power supply line 102. The first end of the first power-taking copper column 1021 is located inside the main board body 1 and is electrically connected to the first auxiliary power supply line 102. The second end of the first power-taking copper column 1021 passes through the main board body 1 and is located outside the main board body 1, and is plugged into a first plug slot of a first voltage conversion module 201.

[0077] like Figure 3As shown, a plurality of second voltage conversion modules 301 are provided on the bridge power supply line 3. Specifically, the second voltage conversion module 301 is a collection module formed by resistors, capacitors, diodes, etc., and its input end can be connected to the bridge power supply line 3 by welding; the plurality of second voltage conversion modules 301 are located between the bridge power supply line 3 and the main board body 1, and the plurality of second voltage conversion modules 301 are electrically connected to the bridge power supply line 3, and a second plug slot is provided on the second voltage conversion module 301.

[0078] like Figure 3 As shown, multiple second auxiliary power supply lines 104 are located inside the main board body 1, and a second power supply copper column 1041 is provided at the second end of the second auxiliary power supply line 104. The first end of the second power supply copper column 1041 is located inside the main board body 1 and is electrically connected to the second auxiliary power supply line 104. The second end of the second power supply copper column 1041 passes through the main board body 1 and is located outside the main board body 1, and is plugged into a second plug slot of a second voltage conversion module 301.

[0079] In the specific use process, such as Figure 2 and Figure 3 As shown, by plugging each first plug-in slot on the main power supply line 2 with the first power copper column 1021 on the main board body 1, and plugging each second plug-in slot on the bridge power supply line 3 with the second power copper column 1041 on the main board body 1, the connection between the main power supply line 2 and the first auxiliary power supply line 102, and the connection between the bridge power supply line 3 and the second auxiliary power supply line 104 can be achieved.

[0080] In this embodiment, by arranging the first voltage conversion module 201 between the main power supply line 2 and the mainboard body 1 and the second voltage conversion module 301 between the bridge power supply line 3 and the mainboard body 1, the space layout utilization of the server mainboard can be improved.

[0081] The first voltage conversion module 201 is provided with a first plug-in slot for plugging into the first power-taking copper column 1021 on the first auxiliary power supply line 102, and the second voltage conversion module 301 is provided with a second plug-in slot for plugging into the first power-taking copper column 1021 on the second auxiliary power supply line 104. The connection method is simple and easy to install and disassemble, thereby facilitating the maintenance of the server.

[0082] In some embodiments not shown, a first adapter tube is rotatably sleeved on the second end of the first power-taking copper column 1021, and the first adapter tube and the second end of the first power-taking copper column 1021 are axially limited. A first thread is provided on the outer wall surface of the first adapter tube, and a second thread matching the second thread is provided on the inner wall surface of the first plug-in slot. The first plug-in slot and the first adapter tube are screwed together. By moving the first plug-in slot up and down and driving the first adapter tube to rotate through the cooperation of the first thread and the second thread, the connection and separation of the first slot and the first power-taking copper column 1021 are realized. Through the cooperation of the first thread and the second thread, the risk of the first plug-in slot and the first power-taking copper column 1021 falling off can be reduced.

[0083] A second adapter tube is rotatably sleeved on the second end of the second power-taking copper column 1041, and the second adapter tube and the second end of the second power-taking copper column 1041 are axially limited. A third thread is provided on the outer wall surface of the second adapter tube, and a fourth thread matching the third thread is provided on the inner wall surface of the second plug-in slot. The second plug-in slot and the second adapter tube are screwed together. By moving the second plug-in slot up and down and driving the second adapter tube through the cooperation of the third thread and the fourth thread, the second adapter tube can be rotated, thereby realizing the connection and separation of the second slot and the second power-taking copper column 1041. Through the cooperation of the third thread and the fourth thread, the risk of the second plug-in slot and the second power-taking copper column 1041 falling off can be reduced.

[0084] In one embodiment, Figure 6 As shown, the main power supply circuit 2 includes a positive circuit 202 and a negative circuit 203 . The surface of the positive circuit 202 is provided with a thermal conductive silicone skin, and the surface of the thermal conductive silicone skin is provided with heat dissipation fins.

[0085] Specifically, the thermally conductive silicone surface can also be set as other types of insulating thermally conductive surfaces, which can prevent the positive return line 202 and the negative return line 203 from short-circuiting and can also dissipate heat.

[0086] In this embodiment, by providing a thermally conductive silicone skin on the positive circuit 202, it is possible to prevent the positive circuit 202 and the negative circuit 203 from short-circuiting and also to dissipate heat. At the same time, dissipating heat fins on the surface of the thermally conductive silicone skin can improve heat dissipation efficiency.

[0087] In one embodiment, Figure 5 As shown, the main power supply line 2 and the bridge power supply line 3 are connected to the main board body 1 through multiple bolts 4, and an insulating ring is provided at the position of the bolts 4 between the main board body 1 and the main power supply line 2 or the bridge power supply line 3.

[0088] Specifically, on the main power supply line 2, the distance between two adjacent bolts 4 is 80mm to 150mm, specifically any one of 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm and 150mm. Of course, it can also be set to other sizes according to actual needs.

[0090] In this embodiment, the main power supply line 2 and the bridge power supply line 3 are both fixed by bolts 4, which has a simple structure and is easy to install and disassemble.

[0091] In one embodiment, Figure 1 、 Figure 5 and Figure 6 As shown, a hot-swap component 5 is provided on the main power supply line 2, and the hot-swap component 5 is detachably connected to the mainboard body 1, such as by a plug-in structure to achieve detachable connection, and the hot-swap component 5 is hot-swapped connected to the power supply module 6.

[0092] In this embodiment, the main power supply line 2 is detachably connected to the mainboard body 1 through the hot-swappable component 5 and the power supply module 6, and is electrically connected to the power supply module 6, which has a simple structure and is easy to install.

[0093] The overall solution of this application is described below with an embodiment.

[0094] According to an embodiment of the present application, a server motherboard is provided, such as Figure 1 and Figure 2 As shown, it includes a main board body 1, a main power supply line 2, at least one bridge power supply line 3 and a hot-swap component 5, and the specific solution is as follows.

[0095] like Figure 1 and Figure 2 As shown, the mainboard body 1 is a PCB circuit board or a circuit board made of other materials; a plurality of first auxiliary power supply circuits 102 and a plurality of first electronic components 101 are provided on the mainboard body 1, and the first ends of the plurality of first auxiliary power supply circuits 102 are electrically connected to the plurality of first electronic components 101 respectively.

[0096] Specifically, the plurality of first electronic components 101 may be a processor, a memory, a hard disk, a graphics card, a RAID card (RAID, Redundant Array of Independent Disks), a network card, a fan, and part of other components on a motherboard.

[0097] The plurality of first auxiliary power supply lines 102 are usually embedded in the main body 1 .

[0098] like Figure 1 As shown, the main power supply circuit 2 is provided on the main board body 1. Specifically, the main power supply circuit 2 can be provided inside the main board body 1, such as Figure 2 As shown, it can also be set outside the main board body 1; the main power supply line 2 extends along the circumference of the main board body 1, the main power supply line 2 is electrically connected to the power supply module 6, and the second ends of multiple first auxiliary power supply lines 102 are all electrically connected to the main power supply line 2.

[0099] In any one of the first auxiliary power supply lines 102 , the connection portion between the main power supply line 2 and the second end of the first auxiliary power supply line 102 is close to the first electronic component 101 to which the first end of the first auxiliary power supply line 102 is connected.

[0100] It needs to be explained that the above-mentioned "main power supply line 2 extends along the circumference of the main board body 1" means that the main power supply line 2 is arranged in a ring on the main board body 1, wherein the ring can be a ring that is connected from end to end, or it can be an incomplete ring that is not connected from end to end; as for the shape of the ring, it can be any shape, such as a square ring, a circular ring, an elliptical ring, a polygonal ring, etc., which can be set according to actual needs, and is preferably a square ring, because the main board body 1 is usually rectangular.

[0101] It should also be noted that the main power supply line 2 extends along the circumference of the main board body 1 and can form a complete ring or an incomplete ring, so that the projection of the main power supply line 2 on the main board body 1 in a direction perpendicular to the main board body 1 can encircle a portion of the first electronic component 101 (that is, a portion of the first electronic component 101 is located on the periphery of the main power supply line 2, and a portion of the first electronic component 101 is located in the inner circle of the main power supply line 2), or it can encircle the entire first electronic component 101.

[0102] More specifically, Figure 1 and Figure 3 As shown, the bridge power supply line 3 can be a conductor with low resistance such as copper wire or silver wire; the bridge power supply line 3 is set on the main board body 1, and the bridge power supply line 3 is electrically connected to the main power supply line 2; Figure 1 As shown, along the first direction X, the projection of the bridge power supply line 3 on the plane where the main board body 1 is located is located on the main board body 1 , and the first direction X is perpendicular to the main board body 1 .

[0103] like Figure 3As shown, at least one second auxiliary power supply line 104 and at least one second electronic component 103 are also provided on the mainboard body 1. The first end of the second auxiliary power supply line 104 is electrically connected to the second electronic component 103, and the second end of the second auxiliary power supply line 104 is electrically connected to the bridge power supply line 3.

[0104] Specifically, the multiple second electronic components 103 can be part of a processor, memory, hard disk, graphics card, RAID card (RAID, Redundant Array of Independent Disks), network card, fan and other components on the motherboard; preferably, the second electronic component 103 is an electronic component located in the middle area of ​​the motherboard body 1, such as a processor, memory stick, graphics card, etc.

[0105] In any second auxiliary power supply line 104 , the bridge power supply line 3 is connected to the second end of the second auxiliary power supply line 104 at a location close to the second electronic component 103 , and the first end of the second auxiliary power supply line 104 is connected to the second electronic component 103 .

[0106] It should be noted that the above-mentioned "along the first direction X, the projection of the bridge power supply line 3 on the plane where the main board body 1 is located is located on the main board body 1, and the first direction X is perpendicular to the main board body 1" means that the bridge power supply line 3 extends inside the main board body 1. As for the extension direction, it can be a straight line, a curved curve, a broken line, etc.; the number can be one or more, and the specific number can be selected and set according to actual needs; its purpose is to avoid the need for overlapping and layered design of the multiple second electronic components 103 densely arranged on the main board and the second auxiliary power supply lines 104 of the main power supply line 2 due to the large number.

[0107] To be more specific, the distance between at least a portion of the second electronic components 103 and the bridge power supply line 3 is less than the distance between them and the main power supply line 2, that is, at least a portion of the second electronic components 103 is far away from the main power supply line 2, and then draws power from the main power supply line 2. On the one hand, the resistance of the second auxiliary power supply line 104 is large, which will cause voltage drop loss. Secondly, when the second auxiliary power supply line 104 extends to the position of the main power supply line 2, there is a risk of crossing with other first auxiliary power supply lines 102 or having limited space, and overlapping settings are required.

[0108] More specifically, Figure 4 As shown, the ends of the main power supply line 2 are not connected, that is, the power supply line does not form a complete ring; the middle part of the main power supply line 2 is electrically connected to the power supply module 6, and the two ends of the main power supply line 2 extend in opposite directions along the circumference of the mainboard body 1.

[0109] More specifically, Figure 2As shown, the main power supply line 2 is spaced apart from the main board body 1; Figure 3 As shown, the bridge power supply line 3 is spaced apart from the main board body 1; that is, a certain distance is set between the main power supply line 2 and the bridge power supply line 3 and the main board body 1 to separate the main power supply line 2 and the preceding power supply line from the main board module.

[0110] Specifically, the interval between the main power supply line 2 and the main board body 1 is 1mm to 10mm, specifically any one of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10mm; it can also be other values, which can be set according to actual needs.

[0111] More specifically, Figure 2 As shown, a plurality of first voltage conversion modules 201 are provided on the main power supply line 2.

[0113] like Figure 3 As shown, a plurality of second voltage conversion modules 301 are provided on the bridge power supply line 3.

The first end of the second power supply copper column 1041 is located inside the main board body 1 and is electrically connected to the second auxiliary power supply line 104. The second end of the second power supply copper column 1041 passes through the main board body 1 and is located outside the main board body 1, and is plugged into a second plug slot of a second voltage conversion module 301.

[0115] To be more specific, a first adapter tube is rotatably sleeved on the second end of the first power-taking copper column 1021, and the first adapter tube and the second end of the first power-taking copper column 1021 are axially limited. A first thread is provided on the outer wall surface of the first adapter tube, and a second thread matching the second thread is provided on the inner wall surface of the first plug-in slot. The first plug-in slot and the first adapter tube are screwed together. By moving the first plug-in slot up and down and driving the first adapter tube to rotate through the cooperation of the first thread and the second thread, the connection and separation of the first slot and the first power-taking copper column 1021 are realized. Through the cooperation of the first thread and the second thread, the risk of the first plug-in slot and the first power-taking copper column 1021 falling off can be reduced.

Through the cooperation of the third thread and the fourth thread, the risk of the second plug-in slot and the second power-taking copper column 1041 falling off can be reduced.
