As shown in FIGS. 1-2, the housing 230 is in the shape of a frame structure. The plurality of Hash boards are disposed side by side in the first accommodation cavity 231 of the housing 230 along the left-right direction. Each of the plurality of Hash boards 230 is perpendicular to the left-right direction, and each Hash board 230 is slidably disposed in the first accommodation cavity 231. Through pushing or pulling the Hash board 210, the Hash board 210 can be installed in or detached from the housing, thus facilitating the installation and uninstallation of the Hash board 210. The power module 220 is disposed in the second accommodation cavity 232 of the housing 230. The control module 240 is slidably disposed in the third accommodation cavity 233 of the housing 230. The power supply module 250 is slidably disposed in the fourth accommodation cavity 234 of the housing 230. Through pushing or pulling the control module 240 and the power supply module 250, the control module 240 and the power supply module 250 can be installed in or detached from the housing, thus facilitating the installation and uninstallation thereof. The fourth accommodation cavity 234 and the third accommodation cavity 233 are distributed in the left-right direction and spaced apart from each other. The electrical connection board 100 is disposed in the housing 230. In this way, the sever 1000 is modularized, which is convenient for the maintenance and installation/uninstallation of each module independently.

The plurality of Hash boards 210, the power module 220, the control module 240, and the power supply module 250 are all connected to the electrical connection board 100; the power module 220 supplies power to the plurality of Hash boards 210 via the electrical connection board 100, and the power supply module 250 supplies power to the control module 240 via the electrical connection board 100, thus achieving the dual circuit power supply of the server 1000.

With respect to the server 1000 of the disclosure, the power module 220 supplies power to the plurality of Hash boards 210 via the electrical connection board 100, the power supply module 250 supplies power to the control module 240 via the electrical connection board 100, thus achieving the dual circuit power supply of the server 1000. The two circuits do not interfere with each other, which improves the stability of the circuits. In addition, the two circuits can be provided with different voltages, and can also provide different voltages to the Hash boards 210 and the control module 240, which improves the adaptability and further improves the security and stability of power supply. When one of the circuits fails, the other circuit will not be affected, so that when one part of a circuit is abnormal, another part of the circuit will not be damaged, thus improving the efficiency of troubleshooting and maintenance. In this way, the sever 1000 is modularized, which is convenient for the maintenance and installation/uninstallation of each module independently.

In certain embodiments, the power module 220 is slidably disposed in the second accommodation cavity 232 of the housing 230, and the extension direction of the power module 230 is the same as that of the plurality of Hash boards 210. The plurality of Hash boards 210, the control module 240 and the power supply module 250 are all disposed on one side of the electrical connection board 100 along the front and rear direction. The front and rear direction is parallel to the extension direction of the plurality of Hash boards 210. In this way, the electrical connection board 100 and the plurality of Hash boards 210, the electrical connection board 100 and the control module 240, and the electrical connection board 100 and the power supply module 250 are connected easily.

In certain embodiments, a plurality of power modules 220 are disposed in the left-right direction, and each power module 220 is configured to supply power for two to four Hash boards 210. For example, the server 1000 comprises twelve Hash boards 210 and four power modules 220, and each power module supplies power for three Hash boards 210, thus improving the efficiency of the server 1000.

In accordance with one embodiment of the disclosure, each Hash board 210 comprises a buck circuit module. The power supply module 220 is configured to convert the first AC voltage of an external first AC into DC and supply the DC to the buck circuit module. The buck circuit module reduces the DC voltage and supplies power to the Hash chip on the Hash board 210. Through the arrangement of the buck circuit module, the high voltage can be converted into low voltage, and the power supply can be provided to the Hash chip on the Hash board 210, which is convenient to realize the dual circuit power supply of the server 1000. For example, the buck circuit module may be disposed on the Hash board 210.

In certain embodiments, the first DC voltage of the DC power converted by the power module 220 is 48 V, and the second DC voltage of the DC power reduced by the buck circuit module of the Hash board 210 is 12 V, which is then input to the Hash chip on the Hash board 210 for power supply. In certain embodiments, the power supply module 250 converts the second AC voltage of the external second AC into the third DC voltage of 12 V and then supplies power to the control module 240, thus achieving the dual circuit power supply of the server 1000 and improving the stability of the circuit.

In certain embodiments, the range of the first AC voltage and the second AC voltage is 220-380 V. The two circuits can be provided with different voltages, and the Hash board 210 and the control module 240 can also be provided with different voltages, thus improving the power supply safety and stability. For example, the first AC voltage can be 380 V or 220 V, and the second AC voltage can be 220 V.

As shown in FIGS. 1 and 9, the control module 240 comprises a control board 241 and a first circuit board 246 disposed on one end of the control board 241 (for example, the rear end in FIG. 1). The first circuit board 246 comprises a first control signal interface 243 and a second control signal interface 245. The first control signal interface 243 is connected to the first port 116 of the electrical connection board 100 for signal connection. The second control signal interface 245 is connected to the second port 117 of the electrical connection board 100 for current transport. The electrical connection board 100 can be disposed at the rear end of the control module 240 to facilitate the connection of the first control signal interface 243 to the electrical connection board 100 thereby achieving the signal connection. The control board 241 can carry the first circuit board 246 to ensure the stable connection between the first circuit board 246 and the electrical connection board 100.

Two sides of the third accommodation cavity 233 is provided with sliding bars, and two sides of the control board 241 are provided with sliding grooves 242. The control board 241 can move in the third accommodation cavity 233 when the sliding bars are sliding in the sliding grooves 242. The arrangement of the sliding bars and the sliding grooves 242 can facilitate the uninstallation of the control module 240, and the signal connection between the control module 240 and the electrical connection board 100 can be turned on or off by sliding the control board 241. As shown in FIG. 9, the control module 240 and the power supply module 250 each comprise a locating base 244, and the electrical connection board 100 is provided with a guide post which can extend into the positioning hole of the locating base 244, so as to facilitate the installation and positioning of the control module 240 and the electrical connection board 100, and the power supply module 250 and the electrical connection board 100, thus improving the installation efficiency of the control module 240 and the electrical connection board 100, and the power supply module 250 and the electrical connection board 100.

As shown in FIG. 10, the power supply module 250 comprises a power supply board 251 and a second circuit board 254 disposed on one end of the power supply board 251. The second circuit board 254 comprises a first current interface 252 and a second current interface 253. The first current interface 252 is configured to connect to the third port 118 of the electrical connection board 100 to access the external voltage, and the second current interface 253 is configured to connect to the fourth port 119 of the electrical connection board 100 to transmit the current. In this way, the power supply module 250 can access the external voltage and transmit the voltage to the electrical connection board 100 electrically connected to the control module 240, so that the power supply module 250 supplies power to the control module 240.

In certain embodiments, the power supply module 250 comprises a protective cover (not shown in the figure). The protective cover is disposed on the second circuit board 254 to protect the second circuit board 254. Optionally, the protective cover can be provided with an opening facing the electrical connection board 100, so as to facilitate the connection of the first current interface 252, the second current interface 253 and the locating base 244 with the electrical connection board 100.

As shown in FIGS. 1 and 10, two sides of the four accommodation cavity 234 is provided with sliding bars, and two sides of the power supply board 251 are provided with sliding grooves 242. The power supply board 251 can move in the four accommodation cavity 234 when the sliding bars are sliding in the sliding grooves 242, thus facilitating the uninstallation of the power supply module 250, and the signal connection between the power supply module 250 and the electrical connection board 100 can be turned on or off by sliding the power supply board 251.

For example, an external 380 V or 220 V AC voltage is introduced and converted by the power module 220 into 48 V DC voltage. The Hash board 210 can be equipped with a buck circuit module to reduce the DC voltage to 12 V, and then input to the Hash chip on the Hash board 210 for power supply. In addition, the power supply module 250 can receive a 220 V AC voltage from outside or from the electrical connection board 100, and convert the 220 V AC voltage into a 12 V DC voltage, and then supply the power for the control module 240. In this way, the control module 240 and the Hash board 210 are separately powered, realizing the dual circuit power supply of the server 1000.

Optionally, the server 1000 is provided with a fifth port 260 for receiving an external voltage (for example, 220 V AC voltage), and the second port 117 is connected to the first current interface 252, so that the voltage can be connected to the power supply module 250 through the electrical connection board 100. The first circuit board 246 can be a buck circuit board, thereby reducing the voltage (for example, convert 220 V AC voltage into 12 DC voltage). The second current interface 253 of the power supply module 250 (for example, the second current interface 253 can be a gold finger interface) can be plugged into the fourth port 119 of the electrical connection board 100 to transmit the voltage to the electrical connection board 100 to supply power to the control module 240.

Specifically, the electrical connection board 100 can transmit current to the first port 116, and the control module 240 comprises the first control signal interface 243 and the second control signal interface 245. For example, the first control signal interface 243 can be connected to the first port 116 to receive the current, so that the power supply module 250 can supply power to the control module 240. The second control signal interface 245 may be connected to the second port 117 of the electrical connection board 100 to transmit information, for example, transmitting control information and receiving feedback information. Optionally, the electrical connection board 100 can also transmit the current to the second port 117, the second control signal interface 245 can be connected to the second port 117 to receive the current, and the first control signal interface 243 can be connected to the first port 116 to transmit information, which is not limited here.

For example, as shown in FIGS. 9 and 10, the first circuit board 246 and the second circuit board 254 can respectively protrude out of the rear ends, as shown in FIG. 4, of the control board 241 and the power supply board 251, so that a plurality of interfaces can be connected to a plurality of ports, and the connection is stable. The first circuit board 246 can be fixedly disposed on the control board 241 through a plurality of fastening screws 270, and the second circuit board 254 can be fixedly disposed on the power supply board 251 through a plurality of fastening screws 270, thereby improving the connection stability.

For example, the control board 241, the power supply board 251, and the protective cover are all made of metal materials thus ensuring the good structural strength of the control module 240 and the power supply module 250. At the same time, the control board 241 and the power supply board 251 are both provided with the sliding grooves 242, which can facilitate the sliding cooperation between the sliding grooves 242 and the sliding bars, ensure the smooth sliding of the sliding grooves 242 and the sliding bars, and facilitate the detachable connection between the power supply board 251/the control board 241 and the housing 230, thus improving the reliability of the electrical connection or disconnection between the power supply module 250 and the electrical connection board 100, and between the control module 240 and the electrical connection board 100.

In certain embodiments, as shown in FIGS. 3-8, the electrical connection board 100 comprises a PCB substrate 10, a first conductive layer 20, a second conductive layer 30, a third conductive layer 40, a first conductive strip 50 and a second conductive strip 60. The PCB substrate 10 comprises two contact areas 11 configured to connect to the positive and negative electrodes of a power supply, respectively, and two sides of each contact area 11 are respectively provided with a first contact surface (not shown in the figure) and a second contact surface 112 configured to contact a conductor. “Two sides of the contact area 11” refer to two sides in the front and rear direction, for example, as shown in FIG. 3 and FIG. 4. Each contact area 11 comprises a plurality of through holes 113. As shown in FIG. 3, FIG. 7 and FIG. 8, the first contact surface and the second contact surface 112 are disposed oppositely to each other along the front and rear direction as shown in FIG. 3, and the through hole 113 runs through the first contact surface and the second contact surface 112 along the front and rear direction as shown in FIG. 3.

The first conductive layer 20 is disposed on the first contact surface, the second conductive layer 30 is disposed on the second contact surface 112, and the third conductive layer 40 is disposed in the through hole 113 and electrically connected to the first conductive layer 20 and the second conductive layer 30. The first conductive strip 50 is fixed on the first conductive layer 20 and electrically connected to the first conductive layer 20, and the first conductive strip 50 is configured to connect to the power module 220. The second conductive strip 60 is connected to the second conductive layer 30 and electrically connected to the second conductive layer 30, and the second conductive strip 60 is electrically connected to the Hash board 210 of the server 1000. The PCB substrate 10 is also provided with a screw hole 114, and the first conductive strip 50, the second conductive strip 60 and the PCB substrate 10 are connected by screws.

Thus, the first conductive layer 20, the second conductive layer 30, and the third conductive layer 40 can be connected as a whole, so that the two sides in the front and rear direction of the PCB substrate 10 can be connected to form a conductor. In this way, there is no need to empty the electrical connection board 100 to pass the conductive strip through the electrical connection board 100 to achieve conductivity, thus ensuring the structural reliability of the electrical connection board 100. At the same time, the structural restriction of the electrical connection board 100 on the first conductive strip 50 and the second conductive strip 60 is avoided, so that the first conductive strip 50 and the second conductive strip 60 can be designed to be larger or smaller as needed, presenting in a variety of forms, so that the electrical connection board 100 is compatible with a variety of servers 1000. In addition, the PCB substrate 10 in such a design mode avoids the coupling between the first conductive strip 50 and the second conductive strip 60, and only the first conductive strip 50 or the second conductive strip 60 can be removed, which is convenient for the installation and uninstallation of the electrical connection board 100, and improves the replacement efficiency and maintenance efficiency.

In certain embodiments, as shown in FIGS. 4 and 7, the electrical connection plate 100 further comprises two conductive connection plates 70 and an insulating layer 80. The two conductive connection plates 70 are respectively connected to the second conductive strips 60 of the two contact areas 11 to connect to the positive electrode and the negative electrode of the power supply respectively. Each conductive connection plate 70 is provided with a plurality of conductive pins 71, and the conductive pins 71 on the two conductive connection plates 70 match each other one by one to form a plurality of pairs of conductive pins 71. For example, the two conductive pins 71 disposed in the up and down direction as shown in FIG. 4 form a pair of conductive pins 71. Each pair of conductive pins 71 corresponds to each Hash board 210 and is electrically connected to the Hash board 210 for power supply.

Thus, owing to the arrangement of the conductive pins 71, a plurality of Hash boards 210 can be directly inserted into the electrical connection board 100, without the use of the screws, thus omitting the removal and installation of the screws, simplifying the operation steps, and improving the maintenance efficiency. In addition, the plurality of conductive pins 71 of the electrical connection board 100 can be respectively connected to the plurality of Hash boards 210 to supply power to the plurality of Hash boards 210 at the same time, no need to providing a plurality of electrical connection boards 100, which improves the integration degree of the server 1000 and saves the cost and operation steps.

For example, the conductive connection plate 70 at the upper end as shown in FIG. 4 is connected to the contact area 11 at the left end as shown in FIG. 4, and the contact area 11 can be connected to the negative electrode of the power supply, so that the conductive connection plate 70 is connected to the negative electrode of the power supply. The conductive connection plate 70 at the lower end as shown in FIG. 4 is connected to the contact area 11 at the right end as shown in FIG. 4, and the contact area 11 can be connected to the positive electrode of the power supply, so that the conductive connection plate 70 can be connected to the positive electrode of the power supply, thus achieving the transmission of current.

In certain embodiments, as shown in FIGS. 4 and 6, the first conductive strip 50 comprises a first conductive sheet 51, a second conductive sheet 52 and a connection sheet 53. The first conductive sheet 51 is connected to the first conductive layer 20, and the second conductive sheet 52 is connected to the power supply module 220. The connection sheet 53 is disposed between the first conductive sheet 51 and the second conductive sheet 52. The first conductive sheet 51, the second conductive sheet 52 and the connection sheet 53 disposed in this way facilitates the connection between the first conductive strip 50 and the power supply module 220. The second conductive sheet 52 comprises a hole 521 through which a fastener passes so that the power module 220 can be firmly connected to the first conductive strip 50.

In certain embodiments, as shown in FIG. 4, the electrical connection board 100 further comprises an insulating layer 80 disposed between the two conductive connection plates 70 to avoid short circuit between the conductive connection plates 70 connecting the positive electrode and the negative electrode of the power supply. The insulating layer 80 is disposed at the positive electrode of the conductive connection plate 70. The insulating layer 80 can be an insulating material coated or plated on the conductive connecting plate 70 of the positive electrode. The insulating layer 80 has good stability and can effectively avoid short circuit between the two conductive connecting plates 70. Optionally, in other embodiments, the insulating layer 80 may be disposed at the negative electrode of the conductive connection plate 70, which is not limited in the disclosure.
