Meanwhile, the power supply module 250 may receive a 220V voltage from the outside or the electrical connection board 100, convert the 220V ac voltage into a 12V dc voltage through the power supply module 250, and then supply power to the control module 240, so that the control module 240 and the computing power board 210 are separately supplied with power, thereby implementing dual circuit power supply of the server 1000.

The server 1000 may be provided with a fifth port 280 for receiving an external voltage (e.g., 220V ac voltage), the second port 117 may be 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 may be a step-down circuit board, so that the step-down voltage (e.g., 220V ac voltage to 12V dc voltage) can be further connected, and the second current interface 253 (e.g., the second current interface 253 may be a gold finger interface) of the power supply module 250 may be plugged into the fourth port 119 of the electrical connection board 100, so as to connect the voltage to the electrical connection board 100 to supply power to the control module 240.

Specifically, the electrical connection board 100 can conduct current to the first port 116, and the control module 240 can have a first control signal interface 243 and a second control signal interface 245. For example, the first control signal interface 243 may be connected with the first port 116 to receive current, so that the power supply module 250 may supply power to the control module 240. A second control signal interface 245 can be connected to the second port 117 of the electrical connection board 100 to transmit information, such as sending control information and receiving feedback information. Of course, the electrical connection board 100 can also conduct current to the second port 117, the second control signal interface 245 can be connected with the second port 117 to receive current, and the first control signal interface 243 can be connected with the first port 116 to transmit information, which is not limited herein.

For example, as shown in fig. 9 and 10, the first circuit board 246 and the second circuit board 254 may protrude from the control board body 241 and the power supply board body 251 at the rear end as shown in fig. 4, respectively, so that a plurality of interfaces and ports may be correspondingly connected, and the connection is stable. The first circuit board 246 may be fixedly mounted to the control board 241 by a plurality of fastening screws 290, and the second circuit board 254 may be fixedly mounted to the power supply board 251 by a plurality of fastening screws 290, so as to improve the connection stability.

For example, the control board body 241, the power supply board body 251 and the protection cover may be made of metal materials, so as to ensure that the structural strength of the control module 240 and the power supply module 250 is good, and meanwhile, the control board body 241, the power supply board body 251 may be provided with the slide rail 242, so as to facilitate the sliding fit between the slide rail 242 and the slide bar, ensure the smooth sliding of the slide rail 242 and the slide bar, facilitate the detachable connection between the control board body 241, the power supply board body 251 and the housing 230, thereby improving the reliability of the connection or disconnection of the electrical connection between the control module 240 and the electrical connection board 100 and the power supply module 250.

In some embodiments, power board 210, control module 240, and power module 250 are all located on one side of electrical connection board 100 along a second direction (e.g., a front-to-back direction as shown in fig. 1 and 2) that is parallel to the direction of extension of power board 210 to facilitate connection of electrical connection board 100 with power board 210, control module 240, and power module 250.

Referring to fig. 1 to 8 and 27, an electrical connection board 100 may include a PCB substrate 10, a first conductive layer 20, a second conductive layer 30, a first conductive strip 50, and a second conductive strip 60, the PCB substrate 10 having two contact regions 11 connected to a positive electrode and a negative electrode of a power supply, respectively, the two sides of each contact region 11 having a first contact surface 111 and a second contact surface 112 adapted to contact a conductor, respectively, and the two sides of the contact region 11 referring to two sides in a front-rear direction as shown in fig. 3 and 4, for example. Each contact region 11 has a plurality of through holes 113 therein. Referring to fig. 7 and 8 in conjunction with fig. 3, the first contact surface 111 and the second contact surface 112 are disposed opposite to each other in, for example, the front-rear direction of fig. 3, the through hole 113 penetrates in, for example, the front-rear direction of fig. 3, and the through hole 113 penetrates the first contact surface 111 and the second contact surface 112.

The first conductive layer 20 is disposed on the first contact surface 111, 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 connects the first conductive layer 20 and the second conductive layer 30. As such, the plurality of vias 113 may be made metallized holes. The term "plated hole" refers to a method of plating the walls of the insulated through holes 113 with a conductive layer by electroless plating and electroplating so as to be reliably connected to each other, and the walls of the through holes 113 may each be provided with a third conductive layer 40 so as to be connected to each other.

The first conductive strip 50 is fixed to the first conductive layer 20 and electrically connected to the first conductive layer 20, the first conductive strip 50 is adapted to be connected 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 computing board 210 of the server 200. Thus, the current flow path may be: the power module 220 conducts the current to the first conductive strip 50, then to the third conductive layer 40 through the first conductive layer 20, then to the second conductive layer 30, and then to the chip on the computing board 210 through the second conductive strip 60, so that the power module supplies power to the computing board.

Thus, the first conductive layer 20, the second conductive layer 30, and the third conductive layer 40 thus provided may be connected to one body, so that both side surfaces of the PCB substrate 10 in the front-rear direction may be connected to one conductor. In this manner, the reliability of the structure of the electrical connection plate 100 can be ensured without having to dig the electrical connection plate 100 to pass a conductive strip through the electrical connection plate 100 to achieve electrical conduction. Meanwhile, the restriction of the electrical connection plate 100 on the structures of the first and second

conductive strips

50 and 60 can be avoided, so that the first and second

conductive strips

50 and 60 can be set to be larger or smaller according to the needs, and can be in various forms, so that the electrical connection plate 100 can be applied to various servers 200. In addition, the PCB substrate 10 thus configured avoids 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 disassembled, which facilitates the disassembly and assembly of the electrical connection board 100, and improves replacement efficiency and maintenance efficiency.

In some embodiments, the first conductive layer 20 and the second conductive layer 30 are each configured as a conductive film plated on the first contact surface 111 and the second contact surface 112. The conductive film can be a conductive film, and the conductive film has good adhesion with the first contact surface 111 and the second contact surface 112, so that the first conductive layer 20 and the first contact surface 111, and the second conductive layer 30 and the second contact surface 112 can be effectively adhered to each other, and smooth passing of current is ensured. For example, the first and second

conductive layers

20 and 30 may cover the entire first and second contact surfaces 111 and 112, respectively. Alternatively, as shown in fig. 8, the first conductive layer 20 and the second conductive layer 30 may avoid the plurality of through holes 113, and both the first conductive layer 20 and the second conductive layer 30 contact the third conductive layer 40 to ensure effective electrical connection between the first conductive layer 20, the second conductive layer 30, and the third conductive layer 40.

According to an embodiment of the present invention, the third conductive layer 40 may be configured as a conductive film plated on the sidewall of the through hole 113 to ensure effective transmission of current. Alternatively, the third conductive layer 40 may be composed of a conductive material passing through the via 113. In this way, the first conductive layer 20, the second conductive layer 30 and the third conductive layer 40 can be communicated, so that the two sides of the electrical connection board 100 can be communicated to form a conductor.

In the example of fig. 3 and 27, the PCB substrate 10 may further have a screw hole 114, and the first conductive strip 50, the second conductive strip 60 and the PCB substrate 10 are connected by a screw, so that the connection stability of the first conductive strip 50, the second conductive strip 60 and the PCB substrate 10 is ensured, and at the same time, the arrangement is easy to detach. For example, both contact areas 11 are provided with screw holes 114, which are riveted or bolted to the first and second

conductive strips

50, 60 and the PCB substrate 10. A plurality of through holes 113 may be provided around the screw holes 114. The diameter ratio of the through hole 113 to the screw hole 114 may range from 1/10 to 1/100, which ensures the connection stability between the first and second

conductive strips

50 and 60 and the PCB substrate 10, and also ensures the effective electrical connection between the first, second and third

conductive layers

20, 30 and 40.

In some embodiments, as shown in fig. 4 and 6, the first conductive strip 50 may include a first conductive sheet 51, a second conductive sheet 52, and a connecting 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 module 220. The connection piece 53 is connected between the first conductive sheet 51 and the second conductive sheet 52. The first conductive sheet 51, the second conductive sheet 52 and the connecting sheet 53 are arranged in this way, so that the connection of the first conductive strip 50 and the power module 220 can be facilitated. For example, the first conductive plate 51, the second conductive plate 52 and the connecting piece 53 may be integrally formed to ensure structural strength of the first conductive strip 50.

Alternatively, referring to fig. 4, 6, and 7, the connection pieces 53 may be configured in an L-shape and perpendicularly connected to the first conductive sheet 51 and the second conductive sheet 52, respectively. For example, the first conductive sheet 51 and the second conductive sheet 52 may be made of copper or copper alloy, so that the ductility and the conductivity of the first conductive sheet 51 and the second conductive sheet 52 are good. Meanwhile, the connecting piece 53 made of copper or copper alloy has good flexibility, is convenient to process and has good structural reliability.

The power module 220 may be disposed in the second receiving space 232 of the housing 230, and the connection piece 53 having an L shape may facilitate the second conductive sheet 52 to extend into the second receiving space 232, so that the connection between the power module 220 and the first conductive strip 50 is facilitated, and the connection stability thereof is further improved. The second conductive sheet 52 may be provided with a through hole 521, and a screw may pass through the through hole 521 to firmly connect the power module 220 and the first conductive strip 50. In addition, the connecting pieces 53 are vertically connected to the first conductive sheet 51 and the second conductive sheet 52, respectively, so that the occupied space can be reduced, and the internal parts of the server 200 can be compact.

In some examples, referring to fig. 4 and 7, the electrical connection board 100 may further include two conductive connection boards 70 and an insulating layer 80, the two conductive connection boards 70 are respectively connected to the second conductive strips 60 of the two contact areas 11 to respectively connect the positive pole and the negative pole of the power supply, each conductive connection board 70 is provided with a plurality of conductive pins 71, and the conductive pins 71 on the two conductive connection boards 70 form a plurality of pairs of conductive pins 71 in a one-to-one correspondence. For example, the two conductive pins 71 aligned in the up-down direction of fig. 4 may be a pair of conductive pins 71. Each pair of conductive pins 71 corresponds to each force calculation plate 210 one by one and is electrically connected to supply power to the force calculation plates 210. An insulating layer 80 is provided between the two conductive connection plates 70 to avoid short circuits between the conductive connection plates 70 connecting the positive and negative poles of the power supply.

Therefore, through the arrangement of the conductive pins 71, the electric connection board 100 can be directly plugged in the force calculation boards 210, the arrangement of screws is omitted, the steps of disassembling and assembling the screws are avoided, the assembling or disassembling can be facilitated, the operation steps are simplified, and the maintenance efficiency is improved. In addition, a plurality of pairs of conductive pins 71 of the electrical connection board 100 can be respectively connected with a plurality of computing power boards 210 so as to simultaneously supply power to the plurality of computing power boards 210, and a plurality of electrical connection boards 100 are not required, so that the integration level of the server 200 is improved, and the cost and the operation steps are reduced.

For example, the conductive connecting plate 70 disposed at the upper end as shown in fig. 4 is connected to the contact region 11 disposed at the left end as shown in fig. 4, and the contact region 11 may be connected to the negative electrode of the power source, so that the conductive connecting plate 70 is connected to the negative electrode of the power source. The conductive connecting plate 70 provided at the lower end as shown in fig. 4 is connected to the contact region 11 provided at the right end as shown in fig. 4, and the contact region 11 may be connected to the positive electrode of the power supply, so that the conductive connecting plate 70 is connected to the positive electrode of the power supply, thereby realizing the current transmission.

As shown in fig. 4 and 5, the two conductive connection plates 70 are parallel in a length direction of the PCB substrate 10 (e.g., a left-right direction as shown in fig. 4) and spaced apart by a predetermined gap in a height direction of the PCB substrate 10 (e.g., an up-down direction as shown in fig. 4), and a plurality of conductive pins 71 are uniformly spaced apart in the length direction of each conductive connection plate 70 to facilitate connection with the plurality of computation force plates 210.

The insulating layer 80 may be 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, and the insulating layer 80 thus arranged has good stability, so that short circuit between the two conductive connecting plates 70 can be effectively avoided. Of course, the insulating layer may be provided on the negative electrode of the conductive connecting plate 70, which is not limited herein.

In some embodiments, as shown in fig. 14, 16 and 17, the force calculation plate 210 has a mounting seat 211 at an end facing the electrical connection plate 100. Each force calculation plate 210 is provided with two mounting seats 211 arranged up and down, and each pair of conductive pins 71 can extend into the two mounting seats 211. The mounting seat 211 may be a conductive member to conduct current when the conductive pin 71 is inserted into the mounting seat 211. The mounting seats 211 may be disposed on one side of the plate body of the force calculation plate 210 (e.g., one side of the left-right direction in fig. 11), that is, two mounting seats 211 of the same force calculation plate 210 may be disposed on the left side of the plate body of the force calculation plate 210 at the same time, or two mounting seats 211 may be disposed on the right side of the plate body of the force calculation plate 210 at the same time. The mounting seat 211 may be a protruding structure protruding from the plate body of the force calculation plate 210, so as to facilitate the insertion of the conductive pin 71, and ensure the structural reliability of the force calculation plate 210. A first mating member may be disposed in the mounting seat 211, and the conductive pin 71 may be detachably mated with the first mating member. By the arrangement of the first fitting member, the installation can be facilitated, and the reliability of the installation of the conductive pin 71 and the installation seat 211 can be improved.

In some examples, one of a hook and a slot may be disposed in the mounting seat 211, and the other of the hook and the slot may be disposed on the conductive pin 71, so that the force calculating board 210 and the conductive pin 71 can be electrically connected through the engagement of the hook and the slot. Meanwhile, the stability of installation of the installation seat 211 and the conductive pin 71 can be ensured through the arrangement of the clamping hook and the clamping groove.

In other examples, as shown in fig. 14 to 17, the mounting seat 211 may be provided with a mounting hole 213, the inner sidewall of the mounting hole 213 has a spring 214 protruding toward the axis of the mounting hole 213, the conductive pin 71 is formed as a cylinder, and the conductive pin 71 is inserted into the mounting hole 213 to be in abutting connection with the spring 214. The spring 214 is a conductive material. When the conductive pin 71 extends into the mounting hole 213, the conductive pin 71 can press the spring 214 toward the inner sidewall of the mounting hole 213, so as to ensure a certain interaction force between the conductive pin 71 and the conductive socket, and further ensure effective contact between the conductive pin 71 and the conductive socket, thereby realizing current conduction between the conductive pin 71 and the conductive socket, and ensuring reliability of electrical connection between the electrical connection board 100 and the computation board 210.

As shown in fig. 15-17, one end (e.g., the front end as shown in fig. 16) of the mounting seat 211 may be further provided with a circular hole 219, and the circular hole 219 is disposed opposite to the mounting hole 213, so that the circular hole 219 and the mounting hole 213 may penetrate through the mounting seat 211. The aperture of the round hole 219 can be slightly larger than the diameter of the conductive pin 71, and the aperture of the round hole 219 is smaller than that of the mounting hole 213, the round hole 219 has a positioning function on the conductive pin 71, and further, the position eccentricity of the conductive pin 71 caused by processing and assembling errors or stress and other reasons can be avoided, so that the situation that the deformation of the reed 214 in a certain direction is larger and the deformation of the reed 214 in the other relative direction is smaller is avoided, and the uniform contact between the conductive pin 71 and the reed 214 is ensured.

For example, referring to fig. 17, two mounting seats 211 disposed on the same force calculation plate 210 may be staggered in the vertical direction, so that after one conductive pin 71 is inserted into the mounting seat 211 disposed at the upper end, the conductive pin 71 may extend out of the mounting seat 211, and after the other conductive pin 71 is inserted into the mounting seat 211 disposed at the lower end, the conductive pin 71 may not extend out of the mounting seat 211. The guide pin may be attached to the electrical connection plate 100 by a screw, or the guide pin may be integrally formed with the electrical connection plate 100.

Further, as shown in fig. 14 and 15, both ends of the spring 214 may be fixed to inner side walls of the mounting hole 213, and a middle portion of the spring 214 protrudes toward an axis of the mounting hole 213. Thus, the conductive pin 71 can be conveniently inserted into the mounting hole 213, and the conductive pin 71 can be favorably pressed against the spring 214 toward the inner side wall of the mounting hole 213 to generate an interaction force. For example, the side of the spring 214 facing the conductive pin 71 may be curved to reduce the friction between the guide pin and the conductive socket.

In some examples, one end of the spring 214 can be fixed to the inner sidewall of the mounting hole 213 and the other end can be tilted. Thus, the conductive pin 71 can be conveniently inserted into the mounting hole 213, and a certain interaction force between the conductive pin 71 and the conductive seat can be ensured, so that an effective contact between the conductive pin 71 and the conductive seat can be ensured.

In some embodiments, as shown in fig. 24-26, computing power board 210 may include: the force calculating plate body 215, the baffle plate 216 and the handle 217, and a force calculating chip 218 can be arranged on the force calculating plate body 215. The baffle plate 216 is disposed at an end of the force computing board body 215 far from the electrical connection board 100, and the baffle plate 216 is configured such that the force computing board 210 is accommodated in the first accommodating space 231, and the opening of the first accommodating space 231 is closed by the baffle plate 216, thereby protecting the force computing board body 215 and the force computing chip 218, etc. located in the housing 230. A handle 217 may be provided on a side of the blocking plate 216 away from the electrical connection board 100, and by providing the handle 217, a user may control the movement of the computation board 210 by pushing and pulling the handle 217. Of course, the handle 217 may be disposed on a plurality of modules such as the heat dissipation module 260 to facilitate movement of the modules.

It should be noted that the force calculation plate 210 according to the embodiment of the present invention may be an air cooling force calculation plate or a liquid cooling force calculation plate. In some examples, the force computing board 210 is an air-cooled force computing board, the force computing board body 215 may further include a heat sink for dissipating heat of the force computing chip 218, the force computing board 210 is disposed in the first receiving space 231 of the housing 230 and is slidable toward the front side of the housing 230, and the heat dissipation module 260 is disposed at the rear end of the housing 230 and is located corresponding to the force computing board 210, so that the heat dissipation module 260 can effectively dissipate heat of the force computing board 210. In addition, the force calculation plate 210 can be further cooled by the arrangement of the cooling fins.

As shown in fig. 2 and 28, the heat dissipation module 260 includes at least one fan 269 to dissipate heat from the force plate 210. For example, the number of the air-cooling computation force plates is 12, and the fans 269 are four groups each including two fans arranged in the up-down direction of fig. 2. Each set of fans 269 is arranged in the left-right direction as shown in fig. 2, and each set of fans 269 can dissipate heat from 3 force plates 210. Each set of fans 269 may each have a socket electrically connected to the electrical connection board 100, so that the connection of the heat dissipation module 260 to the electrical connection board 100 does not need to be through a wire, so that the structure of the server is simple and tidy.

In other examples, as shown in fig. 18-26, computing force plate 210 may be a liquid-cooled computing force plate. In some embodiments, with reference to fig. 19 and fig. 22, the force computing board 210 may further include a voltage reduction circuit module 270, and the voltage reduction circuit module 270 may be electrically connected to the power module 220 of the server 1000 to perform a voltage reduction function, and then input the voltage reduction function to the force computing chip 218 to supply power. The voltage step-down circuit module 270 is disposed on the force computing board body 215 and spaced apart from the force computing chip 218 in a second direction (e.g., a front-rear direction as shown in fig. 18), which is parallel to the extending direction of the force computing board 210.

The heat dissipation module 260 may include at least one first cooling plate 261, a water cooling plate 262, and at least one heat pipe 263, the first cooling plate 261 being disposed on the voltage drop circuit module 270, the water cooling plate 262 being disposed on one side surface of the force calculation plate body 215, and the heat pipe 43 being disposed on the force calculation plate body 215. It should be noted that the medium in the pipe of the "water-cooling plate 262" is not particularly limited to water, and may be various liquids. The heat pipe 263 is a heat transfer element with high heat conductivity, which transfers heat by evaporation and condensation of liquid in the pipe, when one end of the heat pipe 263 is heated, the liquid is vaporized by heat, the vapor goes from the heated end to the other end, the temperature of the other end is low, the vapor is liquefied by cooling, and the condensed liquid can return to the heated end by, for example, capillary force. The liquid in the heat pipe 263 is continuously vaporized and liquefied by the reciprocating circulation, the liquid absorbs and emits a large amount of heat respectively during vaporization and liquefaction, the two ends of the heat pipe 263 have temperature difference, and the heat can be quickly conducted, so that the refrigeration effect can be achieved.

Meanwhile, the water cooling plate 262 and the first cooling plate 41 can also play a role in heat dissipation. The voltage reduction circuit module 270 can transfer heat to the first cooling plate 261, the first cooling plate 261 can dissipate heat, and the first cooling plate 261 can transfer heat to the heat pipe 263, so that the heat dissipation of the heat dissipation module 260 can be realized, and the heat dissipation effect is improved. In addition, since the water-cooling plate 262 has a certain thickness, by providing the first cooling plate 261, it is possible to easily control a difference in height between both ends of the heat pipe 263, so as to facilitate the installation of the heat pipe 263. In addition, one end of the heat pipe 263 is lapped on the first cooling plate 261, and the first cooling plate 261 can have a large contact area with the voltage-reducing circuit module 270, so that the contact area between the heat dissipation module 260 and the voltage-reducing circuit module 270 is increased, the heat transfer efficiency and effect are improved, and the heat dissipation of the voltage-reducing circuit module 270 can be more effectively performed.

From this, through set up heat pipe 263 on calculation board plate body 21, and the one end of heat pipe 263 is taken on first cooling plate 261, and the other end is taken on water-cooling plate 262, can establish the heat transfer passageway, and then can omit radiator fan's setting, reduced the energy consumption, the cost is reduced and can make server 1000 noiselessness when the heat dissipation, radiating effect and thermal stability are good simultaneously, and can realize remote heat dissipation. Meanwhile, the utilization efficiency of the water cooling plate 262 is increased, and the heat dissipation efficiency of the voltage reduction circuit module 270 can be improved. In addition, the problems of heat dissipation cascade, hot air backflow and the like of the voltage reduction circuit modules 270 on the plurality of computation force plates 210 are avoided, and further the diversified design of the voltage reduction circuit modules 270 can be facilitated. In addition, the first cooling plate 261, the water cooling plate 262 and the heat pipe 263 of the heat dissipation module 260 are cooperatively arranged, so that the heat dissipation effect can be further improved.

The voltage reduction circuit module 270 may have an inductance module and a mos (field effect transistor), and the heat pipe 263 may effectively dissipate heat of the inductance module and the mos, so as to avoid overheating of the inductance module and the mos, and ensure working stability of the voltage reduction circuit module 270. Of course, in other embodiments, the voltage-reducing circuit module 270 may also be other structures requiring heat dissipation, such as a power supply and a circuit board. By designing one water cooling plate 262, the power calculating chip 218 of the power calculating plate body 215 can be radiated, and the voltage reduction circuit module 270 on the power calculating plate body 215 can be radiated, so that the heat radiation capability of the water cooling plate 262 is fully utilized, and the fanless design is realized.

In some embodiments, the first cooling plate 261 may include a plurality of first cooling plates 261 arranged at intervals on the voltage-decreasing circuit module 270, each first cooling plate 261 corresponding to at least one heat pipe 263. In other embodiments, the first cooling plate 261 may include one, and one end of all the heat pipes 263 is lapped on the first cooling plate 261. The layout design of the voltage step-down circuit block 270 may be selected from various designs. For example, the design of the nearby power supply is distributed, or the concentrated power supply and the concentrated heat dissipation are performed. The heat dissipation module 260 may be configured for the design of the voltage reduction circuit module 270 to further improve the heat dissipation effect.

For example, the heat pipe 263 may be a copper pipe or an aluminum alloy pipe, so that the heat pipe 263 has good structural strength, can perform effective heat dissipation, and has good flexibility, thereby facilitating the heat pipe 263 to be configured into various shapes in cooperation with the design of the voltage reduction circuit module 270 and the water cooling plate 262.
