It should be noted that in FIG. 3 , the power adapter assembly 10, the first power supply unit 20, the circuit board assembly 30, the first electrical device 40, the second power supply unit 50, and the second electrical device 60 are all located inside a chassis. Among them, the circuit board assembly 30 can be a straight backplane.

Specifically, the chassis includes a front panel and a rear panel that are arranged opposite to each other along the Y-axis direction. The front panel faces the negative direction of the Y-axis, and the rear panel faces the positive direction of the Y-axis. The rear panel is provided with a notch, and the notch is used to provide space for the server 200 to access the first power distribution unit 300 and the second power distribution unit 400.

The power adapter assembly 10 is installed in the chassis near the rear panel. The power adapter assembly 10 includes a first connector 11, a second connector 12, a third connector 13 and a fourth connector 14. The interface of the first connector 11 is opposite to the interface of the rear panel. The notch is exposed to realize electrical connection between the first connector 11 and the first power distribution unit 300 and the second power distribution unit 400, thereby realizing electrical connection between the server 200 and the first power distribution unit 300 and the second power distribution unit 400, and at the same time realize connecting the first voltage to the power adapter component 10, thereby realizing connecting the first voltage to the server 200.

The first power supply unit 20 is installed in the chassis near the front panel. Specifically, each first power supply unit 20 includes an input terminal 21 and an output terminal 22. The input terminal 21 includes two input terminals, a main input terminal 211 and a standby input terminal 212. The input terminals 21 of the first power supply unit 20 are electrically connected to the second connector 12 of the power adapter component 10 to achieve an electrical connection between the first power supply unit 20 and the power adapter component 10. Among them, each first power supply unit 20 is used to receive a first voltage and convert the first voltage into a second voltage. Exemplarily, there are six first power supply units 20, and the second voltage is a direct current of 48V or 54V. In this embodiment, each first power supply unit 20 includes two input terminals 21. A main input terminal 211 of each first power supply unit 20 is used to access the first voltage of the main circuit, and the standby input terminal 212 is used to access the first voltage of the standby circuit, so that when the first voltage of the main circuit fails, the first voltage of the standby circuit can still supply power to the first power supply unit 20, thereby achieving the effect of dual input first voltage. The input end of the first power supply unit 20 can also be set to one, so that multiple first power supply units 20 can be set, and the input ends of some first power supply units 20 are used to connect to the first voltage of the main circuit, and the input ends of other first power supply units 20 are used to connect to the first voltage of the backup circuit.

The circuit board assembly 30 is electrically connected to the output end 22 of the first power supply unit 20, and is also electrically connected to the third connector 13 of the power adapter assembly 10, so that the first power supply unit 20 is electrically connected between the second connector 12 and the third connector 13, thereby enabling the second voltage to flow to the power adapter assembly 10 through the circuit board assembly 30 and be output through the fourth connector 14 of the power adapter assembly 10.

The first electrical devices 40 are electrically connected to the fourth connector 14, respectively, so that the second voltage output by the fourth connector 14 supplies power to the first electrical devices 40. Exemplarily, there are multiple first electrical devices 40, including a 48V upper fan board 40a, a 48V lower fan board 40b, a computing module, etc. The computing module includes components such as a graphics processing unit (GPU) 40c, an FPGA, and a power chip.

The second power supply unit 50 is used to be electrically connected to the first power distribution unit 300 and the second power distribution unit 400 to access the first voltage and convert the first voltage into a third voltage. Exemplarily, the third voltage is 12V direct current. The second power supply unit 50 is electrically connected to the second power device 60 respectively to power the second power device 60 with the third voltage. Exemplarily, there are multiple second power devices 60, including a mainboard 60a of a central processing unit CPU computing module, a 12V fan board 60b, an expansion module (Riser module) 60c, a central processing unit (Central Processing Unit, CPU), memory, etc. Among them, the 12V fan board 60b can be installed on the mainboard 60a, and the expansion module 60c can include an NVME (Non-Volatile Memory Express) disk, a PCIe (Peripheral Component Interconnect Express) card, for example, the expansion module 60c can include 2 NVME disks and 3 PCIe cards.

In the power adapter component 10 provided in the embodiment of the present application, the first connector 11 in the power adapter component 10 is electrically connected to the power distribution module, and the second connector 12 is electrically connected to the input end 21 of the first power supply unit 20, so as to realize the electrical connection between the power distribution module and the first power supply unit 20. While realizing the power adapter component 10 is connected to the first voltage output by the power distribution module, no more cables are required to electrically connect the power distribution module to the first power supply unit 20, thereby realizing simple wiring inside the server 200 and improving the utilization rate of the usable space inside the server 200.

In addition, the third connector 13 in the power adapter assembly 10 can be electrically connected to the output end 22 of the first power supply unit 20 to introduce the second voltage converted by the first power supply unit 20 into the power adapter assembly 10 and output it from the fourth connector 14. The power adapter assembly 10 provided in the present application not only has the function of electrically connecting the power distribution unit and the first power supply unit 20, but also can output the second voltage converted by the first power supply unit 20 through the fourth connector 14, so as to facilitate power supply to the first electrical device 40.

Refer to Fig. 4, which is a partial schematic diagram of the power supply topology of the first power distribution unit 300 and the second power distribution unit 400 to the server 200 shown in Fig. 3. The circuit board assembly 30 is not shown in Fig. 4, and the diagram only shows the current flow diagram, not the actual structural connection and position relationship.

The first power distribution unit 300 outputs the first voltage of the main circuit, which is connected to the server 200 through the first connector 11 of the power adapter assembly 10 (solid line wiring as shown in Figure 4). The first voltage of the main circuit can be connected to the first power supply unit 20 through the input terminal 211 of each first power supply unit 20, and converted into a second voltage through each first power supply unit 20. The second voltage is output to the first electrical device 40 through the output terminal 22 to power the first electrical device 40. In addition, the first voltage of the main circuit can also be converted into a third voltage through the second power supply unit 50 to realize the use of the third voltage to power the second electrical device 60.

When the first voltage of the main circuit output by the first power distribution unit 300 fails, the second power distribution unit 400 starts working and outputs the first voltage of the standby circuit. The first voltage of the standby circuit is connected to the server 200 through the first connector 11 of the power adapter assembly 10 (as shown in the dotted line in Figure 4), and is connected to the first power supply unit 20 through the input terminal 212 of each first power supply unit 20 to supply power to the first power supply unit 20 and ensure the normal operation of the first electrical device 40. In addition, the first voltage of the standby circuit can also be converted into a third voltage through the second power supply unit 50 to supply power to the second electrical device 60, thereby ensuring the normal operation of the second electrical device 60.

In the server 200 provided in this embodiment, the server 200 uses a first power supply unit 20 with two input terminals 21 to facilitate simultaneous access to the first voltage of the main circuit output by the first power distribution unit 300 and the first voltage of the backup circuit output by the second power distribution unit 400 to achieve the effect of a dual-input power signal. Compared with the traditional method, the number of first power supply units 20 is saved and the power of the first power supply unit 20 can be effectively improved.

In some embodiments, when some circuit units or components inside the dual-input first power supply unit 20 or the second power supply unit 50 fail, even if the first voltage of the main circuit output by the first power distribution unit 300 and the first voltage of the backup circuit output by the second power distribution unit 400 are normal, the first power supply unit 20 or the second power supply unit 50 may not work properly. Therefore, in order to improve the reliability of the server 200, on the basis of meeting the number of first power supply units 20 required for the normal operation of each electrical device inside the server 200, one or more redundant power supply modules can be additionally configured. For example, when there are five first power supply units 20, a redundant power supply module of the first power supply unit 20 can be set, and the redundant power supply module is consistent with the type of the remaining first power supply units 20, has a dual input terminal, and can realize the conversion of the first voltage into the second voltage; when there is one second power supply unit 50, a redundant power supply module of the second power supply unit 50 can be set, and the redundant power supply module is consistent with the type of the remaining second power supply units 50, has a dual input terminal, and can realize the conversion of the first voltage into the third voltage. In this way, compared with a single-input power supply unit approach, the number of power supply units can be reduced and higher reliability can be achieved.

In this embodiment, the power adapter assembly 10 further includes a warning mark, which is disposed on the first surface 101a of the adapter circuit board 101. Exemplarily, the warning mark is a pattern or text mark indicating electrical danger.

The power adapter assembly 10 may also include insulating glue. In this embodiment, the insulating glue covers the exposed portion of the pins of the first connector 11 relative to the first surface 101a of the adapter circuit board 101, covers the exposed portion of the pins of the second connector 12 relative to the first surface 101a of the adapter circuit board 101, and covers the exposed portion of the pins of the fourth connector 14 relative to the first surface 101a of the adapter circuit board 101, so as to improve the safety protection performance of the power adapter assembly 10, thereby improving the safety performance of the server 200 and avoiding potential safety accidents.

Refer to Fig. 8, which is a schematic diagram of the current flow between the adapter circuit board 101 and the first connector 11, the second connector 12, the third connector 13 and the fourth connector 14 in the power adapter assembly 10 shown in Fig. 5. The arrow direction shown in Fig. 8 only indicates the current flow direction, and Fig. 8 does not represent the positional relationship of the actual structure.

The adapter circuit board 101 includes a dielectric substrate 1, a first signal layer 2 and a second signal layer 3. The first signal layer 2 and the second signal layer 3 are both arranged in the dielectric substrate 1 and are insulated from each other. Exemplarily, the first signal layer 2 and the second signal layer 3 are both printed circuit layers. In this embodiment, the first signal layer 2 is a wiring layer for 220V AC on the primary side, and the second signal layer 3 is a wiring layer for 48V DC on the secondary side.

The first signal layer 2 is electrically connected between the first connector 11 and the second connector 12 to output the first voltage connected to the first connector 11 from the second connector 12. The first voltage output by the second connector 12 can be converted into a second voltage by the first power supply unit 20, and the second voltage can be output through the electrical connection between the circuit board assembly 30 and the third connector 13. Insert the adapter circuit board 101.

The second signal layer 3 is electrically connected between the third connector 13 and the fourth connector 14 to output the second voltage inputted into the third connector 13 through the fourth connector 14 .

Please refer to FIG. 9 , which is an exploded structural diagram of the cross-sectional structure of the adapter circuit board 101 in the power adapter assembly 10 shown in FIG. 5 .

Specifically, the dielectric substrate 1 includes a plurality of sub-insulating layers 1a, and the plurality of sub-insulating layers 1a are stacked. Among them, the first surface of the dielectric substrate 1 is the first surface 101a of the adapter circuit board 101, and the second surface of the dielectric substrate 1 is the second surface 101b of the adapter circuit board 101. Among them, the power adapter component 10 uses energy-saving plates, and is a plate that has passed the IEC/EN/UL60950-1 and IEC/EN/UL62368-1 temperature cycle test certification. In this embodiment, the material of each sub-insulating layer 1a is polypropylene (PP). Exemplarily, the thickness of each sub-insulating layer 1a is ≥0.4mm to meet the requirements of reinforced insulation. In this embodiment, the thickness of each sub-insulating layer 1a is 0.5mm.

The first signal layer 2 and the second signal layer 3 are located between multiple sub-insulating layers 1a, and are insulated from each other and spaced apart. It is understandable that other signal layers may also be provided in the multiple sub-insulating layers 1a, and the present application does not limit this. In the present embodiment, along the direction from the first surface 101a to the second surface 101b, that is, along the negative direction of the Z axis, the first signal layer 2 is located on the surface of the 5th to 8th sub-insulating layers 1a. In the present embodiment, the first signal layer 2 is closer to the first surface 101a of the adapter circuit board 101. In other embodiments, the positions of the first signal layer 2 and the second signal layer 3 may also be swapped, that is, the second signal layer 3 is closer to the first surface 101a.

The sub-insulating layer 1a between the first signal layer 2 and the second signal layer 3 forms an intermediate insulating layer. The thickness of the intermediate insulating layer is L1, that is, along the thickness direction of the adapter circuit board 101, that is, along the Z-axis direction, the distance between the first signal layer 2 and the second signal layer 3 is L1.

In some embodiments, L1 is greater than or equal to 0.4 mm to meet the requirements of enhanced insulation. For example, in some specific embodiments, the effect of enhanced insulation can be achieved by one of the following methods a) and b):

a) The intermediate insulating layer may include at least one sub-insulating layer 1a, and the thickness of each sub-insulating layer 1a is greater than or equal to 0.4 mm, which can ensure that the thickness of the intermediate insulating layer meets the requirements of reinforced insulation. When the thickness of a single sub-insulating layer 1a is greater than or equal to 0.4 mm, the single sub-insulating layer 1a can meet the requirements of reinforced insulation, and the intermediate insulating layer between the first signal layer 2 and the second signal layer 3 includes at least one sub-insulating layer 1a to meet the requirements of reinforced insulation.

b) The intermediate insulating layer may include at least two sub-insulating layers 1a, and at least two layers of sub-insulating layers 1a are stacked. The withstand voltage of the adapter circuit board 101 is greater than or equal to 3000Vac, where 3000Vac means access to 3000V AC voltage. At this time, the thickness of a single sub-insulating layer 1a may be less than 0.4mm. In addition, the thickness of a single sub-insulating layer 1a generally needs to meet at least 10mil (meter-ohm, one thousandth of an inch), where 10mil=10×0.0025cm=0.025cm=0.25mm. A single sub-insulating layer 1a is relatively thin and is not enough to meet the insulation requirements. Therefore, the intermediate insulating layer needs to include at least two sub-insulating layers 1a, and the adapter circuit board 101 can meet the withstand voltage test of 3000Vac to meet the requirements of reinforced insulation.

In some other embodiments, the effect of enhanced insulation can also be achieved by way c):

c) The intermediate insulating layer includes at least one sub-insulating layer 1a, and the thickness of a single sub-insulating layer 1a is less than 0.4mm. In the direction parallel to the surface of the adapter circuit board 101, that is, in the direction parallel to the X-Y plane, the distance between the first signal layer 2 and the second signal layer 3 is L2, wherein 3mm≤L2≤6mm. Since the thickness of a single sub-insulating layer 1a does not meet the insulation requirements, when the intermediate insulating layer has only one sub-insulating layer 1a, one sub-insulating layer 1a can only be regarded as basic insulation. At this time, L2 satisfies 3mm≤L2≤6mm to meet the electrical clearance and creepage distance requirements of the additional insulation, so that after the intermediate insulating layer fails, the first signal layer 2 and the second signal layer 3 can still be insulated from each other to ensure the safety performance of the adapter circuit board 101, thereby ensuring the safety performance of the power adapter assembly 10, and further ensuring the safety performance of the server 200.

Referring to FIG. 10 , FIG. 10 is a schematic diagram of a top view of the power adapter assembly 10 shown in FIG. 5 . The dotted-line frames of the first signal layer 2 and the second signal layer 3 indicate that they are located inside the dielectric substrate 1 .

The output end of the first signal layer 2 is electrically connected to the second connector 12, so that the second connector 12 outputs the first voltage.

The input end of the second signal layer 3 is electrically connected to the third connector 13, so that the third connector 13 inputs the second voltage to the adapter circuit board 101. The output end of the second signal layer 3 is electrically connected to the fourth connector 14, so that the fourth connector 14 outputs the second voltage.

The live terminal 41 and the neutral terminal 42 are both used to electrically connect to the connecting pins of the first connector 11 to achieve electrical connection between the first connector 11 and the adapter circuit board 101. The width of the ground terminal 43 is W, W ≥ 5mm, which can improve the safety performance of the adapter circuit board 101, thereby improving the safety performance of the power adapter assembly 10, and further improving the safety performance of the server 200. Exemplarily, the ground terminal 43 is copper foil, and the copper foil needs to pass at least a 1500A restricted short circuit test.

The conductive member 33 is plugged into the third connector 13 of the first power supply unit 20 to realize signal transmission between the circuit board assembly 30 and the power adapter assembly 10, so as to realize the second voltage is input to the third connector 13 of the power adapter assembly 10 through the circuit board assembly 30, and output from the fourth connector 14 of the power adapter assembly 10.
