[0002] Currently, power connectors are generally used to supply power to servers in the market for AC-DC conversion, converting 220V AC into 12V DC. The current power transmission mode requires soldering various power supplies and Header connectors on the server board, which naturally occupies the board area. However, with the development of server miniaturization, the space on the printed circuit board (PCB) is reduced accordingly. At this time, the package area of the power supply and Header connectors will be compressed into the usage space of other functional components, which cannot meet the actual needs. In addition, due to the special working mode of the server, which is in a continuous working state, the 12V power supply is connected to the printed circuit board through the connector for a long time, which will not only generate huge heat on the printed circuit board, but also interfere with the transmission of low-speed signals, affecting the control and monitoring of the power connector by the server system.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.
[0043] Embodiment 1
[0044] As Figure 1 , Figure 2 shown, in Embodiment 1 of the present application, a power connection device is provided, including a base 2, a housing 3, a plurality of positive pins 4, a plurality of negative pins 5, a positive cable connector 311 and a negative cable connector 321; specifically, the housing 3 is snap-connected to the base 2 to form an installation cavity; a positive cable interface 31 and a negative cable interface 32 are provided at the top of the housing 3; a plurality of positive pins 4 are fixed on the base 2 and arranged in the installation cavity; a plurality of negative pins 5 are fixed side by side with the positive pins 4 on the base 2 and arranged in the installation cavity; the positive cable connector 311 is fixed in the positive cable interface 31 and electrically connected to all the positive pins 4; the negative cable connector 321 is fixed in the negative cable interface 32 and electrically connected to all the negative pins 5.
[0045] It is understandable that all the positive cable connectors 311 can be combined into one positive cable connector 311, and all the negative cable connectors 321 can be combined into one negative cable connector 321. When all the positive cable connectors 311 are combined into one positive cable connector 311, the positive cable connector 311 will be connected to a single positive cable connector 6. When all the negative cable connectors 321 are combined into one negative cable connector 321, the negative cable connector 321 will be connected to a single negative cable connector 7. At this time, the positive cable connector 6 will be connected to other circuit elements through the positive cable, and the negative cable connector 7 will be connected to other circuit elements through the negative cable. When the positive cable connector 6 and the negative cable connector 7 are connected to the same circuit element at the same time, power will be directly supplied to this same circuit element, without passing through the bottom printed circuit board 9 carrying low-speed signals, thus separating the power supply and low-speed signal lines, effectively solving the problem of the power supply generating a large amount of heat on the bottom printed circuit board 9. At the same time, the reduction of the heat on the bottom printed circuit board 9 also reduces the interference to the transmission of low-speed signals.
[0046] In addition, a single positive cable connector 311 and a single negative cable connector 321 can also be combined into one cable connector. At this time, the positive cable connector 6 and the negative cable connector 7 can also be combined into one cable connector. The combined cable connector is connected to the combined cable connector, and the combined cable connector is then connected to other circuit elements. At this time, the power connection device can directly supply power to other circuit elements without passing through the bottom printed circuit board 9 carrying low-speed signals, thus separating the power supply and low-speed signal lines, effectively solving the problem of the power supply generating a large amount of heat on the bottom printed circuit board 9. At the same time, the reduction of the heat on the bottom printed circuit board 9 also reduces the interference to the transmission of low-speed signals.
[0047] As Figure 1 shown, the multiple positive pins 4 include three groups of positive pins 4, and the multiple negative pins 5 include three groups of negative pins 5. The three groups of positive pins 4 and the three groups of negative pins 5 are fixed side by side on the base 2; the three groups of positive pins 4 and the three groups of negative pins 5 are a combination of multi-row pins. When the current in the power cable passes through the power connection device, the multi-row combined positive pins 4 and negative pins 5 can shunt the large circuit of the power cable, protecting the positive pins 4 and negative pins 5 to the greatest extent, thus protecting the stability of the power cable in transmitting current, and at the same time effectively reducing the possibility of the positive pins 4 and negative pins 5 being burned out.
[0048] As Figure 1As shown in the figure, in this embodiment, the power connection device further includes a top printed circuit board 1, which is disposed in the installation cavity and electrically connected to the positive electrode pin 4 and the negative electrode pin 5 respectively; the positive cable connector 311 is electrically connected to all the positive electrode pins 4 on the top printed circuit board 1; the negative cable connector 321 is electrically connected to all the negative electrode pins 5 on the top printed circuit board 1. The top printed circuit board 1 can conduct the positive electrode pin 4 and the positive cable connector 311, and the top printed circuit board 1 can conduct the negative electrode pin 5 and the negative cable connector 321.
[0049] It can be understood that the top printed circuit board 1 is disposed in the installation cavity and located between the housing 3 and all the positive electrode pins 4 and negative electrode pins 5, which can shorten the electrical connection lines from the positive electrode pin 4 and the negative electrode pin 5 to the top printed circuit board 1 to the greatest extent, and can also shorten the electrical connection lines between the positive cable connector 311 and the negative cable connector 321 to the greatest extent. In this way, the current loss of the power supply cable when passing through the power connection device can be reduced, a part of the current can be saved, and at the same time, the heat loss of the power supply cable when passing through the power connection device can be reduced, and the energy consumption can be reduced. The positive cable connector 311 is electrically connected to all the positive electrode pins 4 on the top printed circuit board 1, and the negative cable connector 321 is electrically connected to all the negative electrode pins 5 on the top printed circuit board 1. In this way, the top printed circuit board 1 can conduct the connection between the positive and negative currents of the power supply cable and the currents of the positive and negative cable connectors 311 to form a current path, ensuring the functional use of the current connection device.
[0050] As Figure 1 shown in the figure, in this embodiment, the top printed circuit board 1 is provided with at least two rows of positive connection holes 11, and the positive electrode pin 4 is provided with at least two rows of positive sub-pins 41 arranged at intervals, and each row of positive sub-pins 41 is fixed in one row of positive connection holes 11.
[0051] It can be understood that at least two rows of positive sub-pins 41 arranged at intervals on the positive electrode pin 4 can make the power connection device more beautiful and space-saving when the current of the power module passes through the current connection device. At the same time, the current of the power module can be well shunted, and the positive electrode pin 4 can be protected from being burned to the greatest extent. Making each row of positive sub-pins 41 fixed in one row of positive connection holes 11 can stably conduct the current of the positive electrode pin 4 into the top printed circuit board 1 when the current of the power module passes through the current connection device. When the power module is connected to the power connection device, the stability of the current output connection of the current module is ensured. The at least two rows of positive sub-pins 41 arranged can well shunt the current of the power module and protect the positive electrode pin 4 from being burned to the greatest extent.
[0052] As Figure 1 shown, in this embodiment, the top printed circuit board 1 is provided with at least two rows of negative connection holes 12, and the negative pin 5 is provided with at least two rows of negative sub-pins 52 arranged at intervals. Each row of negative sub-pins 52 is fixed in a row of negative connection holes 12.
[0053] It can be understood that at least two rows of negative sub-pins 52 arranged at intervals of the negative pin 5 can, when the current of the power supply module passes through the current connection device, make the reasonable arrangement of the negative pin 5 make the power connection device more beautiful and space-saving. At the same time, it can also well shunt the current flowing into the power supply module, protecting the negative pin 5 from being burned to the greatest extent. Making each row of negative sub-pins 52 fixed in a row of negative connection holes 12 can, when the current flowing into the power supply module passes through the current connection device, stably conduct the current of the top printed circuit board 1 into the negative pin 5. The power connection device connecting the power supply module ensures the stability of the input current connection of the current module. The arranged at least two rows of negative sub-pins 52 can well shunt the current of the power supply module, protecting the negative pin 5 from being burned to the greatest extent.
[0054] As Figure 1 shown, in this embodiment, the row where the positive connection hole 11 is located is arranged in parallel with the row where the negative connection hole 12 is located.
[0055] It can be understood that the parallelly arranged positive connection hole 11 and negative connection hole 12 can reasonably arrange the circuit on the top printed circuit board 1, and can reduce the mutual influence between the currents in each pin when the current flows through the top printed circuit board 1 during the process of the power supply module being connected to the power connection device and the output and input of current between the power supply module and the power connection device, ensuring the stability of the current connection, and at the same time reducing the heat loss. Due to the reasonable circuit arrangement on the top printed circuit board 1 and the parallelly arranged positive connection hole 11 and negative connection hole 12, the area of the top printed circuit board 1 can be reduced when installing the top printed circuit board 1, and it can also be achieved that while reducing the area of the top printed circuit board 1, the overall volume of the current connection device is reduced, making the overall current connection device more concise.
[0056] As Figure 1 、 Figure 2 、 Figure 3 shown, in this embodiment, the power connection device further includes a positive cable connector 6 and a negative cable connector 7. The positive cable connector 6 is pluggably connected to the positive cable joint 311; the negative cable connector 7 is pluggably connected to the negative cable joint 321.
[0057] It is understandable that all the positive cable connectors 311 can be combined into one positive cable connector 311, and all the negative cable connectors 321 can be combined into one negative cable connector 321. When all the positive cable connectors 311 are combined into one positive cable connector 311, the positive cable connector 311 will be connected to a single positive cable connector 6. When all the negative cable connectors 321 are combined into one negative cable connector 321, the negative cable connector 321 will be connected to a single negative cable connector 7. At this time, the positive cable connector 6 will be connected to other circuit components through the positive cable, and the negative cable connector 7 will be connected to other circuit components through the negative cable. When the positive cable connector 6 and the negative cable connector 7 are connected to the same circuit component at the same time, power will be directly supplied to this same circuit component without passing through the bottom printed circuit board 9 carrying low-speed signals, thus separating the power supply and low-speed signal lines, effectively solving the problem of the power supply generating a large amount of heat on the bottom printed circuit board 9. At the same time, the reduction of the heat on the bottom printed circuit board 9 also reduces the interference to the low-speed signal transmission.
[0058] In addition, a single positive cable connector 311 and a single negative cable connector 321 can also be combined into one cable connector. At this time, the positive cable connector 6 and the negative cable connector 7 can also be combined into one cable connector. The combined cable connector is connected to the combined cable connector, and the combined cable connector is then connected to other circuit components.
[0059] It is understandable that the positive cable connector 6 is pluggable to the positive cable connector 311, the negative cable connector 7 is pluggable to the negative cable connector 321, and the combined cable connector is pluggable to the combined cable connector, which can facilitate the connection, disassembly, and installation when the power connection device is connected to other circuit components after the power module and the power connection device are connected. The cable connector can be detachably connected to the power cable, that is, after the power module and the power connection device are connected, and the power connection device and the cable connector are connected, it is convenient to connect, disassemble, and install to other circuit components.
[0060] Such as Figure 1 、 Figure 3 As shown in the figure, in this embodiment, the power connection device further includes a plurality of signal pins 8. The plurality of signal pins 8 are fixedly arranged side by side with the positive pin 4 and the negative pin 5 on the base 2 and are arranged in the installation cavity.
[0061] It can be understood that in the installation cavity formed by the snap connection of the base 2 and the housing 3, there are four consecutive positive pins 4, four consecutive negative pins 5, and seven consecutive signal pins 8. The positive pins 4, negative pins 5, and signal pins 8 are fixedly arranged side by side on the base 2 in sequence. The base 2 is made of insulating material to ensure the stable transmission of current in the positive pins 4 and negative pins 5 and the stable transmission of signals in the signal pins 8. At this time, when the power module is inserted into multiple positive pins 4, multiple negative pins 5, and signal pins 8 of the power connection device, the current of the positive and negative poles will conduct through multiple positive pins 4 and multiple negative pins 5 to the top printed circuit board 1. The current conducted to the top printed circuit board 1 will conduct through the top printed circuit board 1 to the positive cable connector 311 and the negative cable connector 321, and then conduct to other circuit elements connected to the positive cable connector 311 and the negative cable connector 321, completing the power supply process of the power module to the power connection device and other circuit elements. When the current of the power module passes through the power connection device, the signal of the signal pin 8 will also transmit the signal to the low-speed signal line in the bottom printed circuit board 9 through the circuit connection device, completing the signal transmission.
[0062] As Figure 2 , Figure 3 , Figure 4 shown, in this embodiment, the power connection device further includes a bottom printed circuit board 9, and the bottom printed circuit board 9 is arranged below the base 2; a through hole 91 for passing through the signal pin 8 is provided on the base 2; the signal pin 8 passes through the through hole 91 and is electrically connected to the bottom printed circuit board 9.
[0063] It can be understood that in the area of the signal pin 8 of the base 2, there are multiple pupils arranged side by side on the base 2 in sequence. Multiple signal pins 8 are inserted into multiple through holes 91 arranged side by side in sequence. The multiple through holes 91 can effectively fix the positions of the signal pins 8. The signal pins 8 in the power connection device are electrically connected to the bottom printed circuit board 9 through the through holes 91. When the current of the power module passes through the power connection device, the signal pin 8 sends a signal to the bottom printed circuit board 9, and the signal is transmitted to the low-speed signal line of the bottom printed circuit board 9, completing the signal transmission.
[0064] In this embodiment, a low-speed signal line is provided in the bottom printed circuit board 9, and the low-speed signal line is electrically connected to the signal pin 8.
[0065] It can be understood that the low-speed signal line in the bottom printed circuit board 9 is used to transmit the low-speed signal sent out by the signal pin 8. When the current of the power module passes through the power connection device, the low-speed signal line in the bottom printed circuit board 9 receives the low-speed signal transmitted from the signal pin 8 in the power connection device, and the low-speed signal is transmitted in the low-speed signal line and transmitted to the server, completing the signal transmission.
[0066] When the current of the power supply module passes through the power connection device, the signal pin 8 in the power connection device will transmit a signal to the bottom printed circuit board 9 through the via hole 91, and the low-speed signal line in the bottom printed circuit board 9 is used to transmit the signal sent by the signal pin 8. In this way, when the current of the power supply module passes through the power connection device, the positive and negative currents will pass through multiple positive pins 4 and multiple negative pins 5 to conduct to the top printed circuit board 1 to supply power to the positive cable connector 311, the negative cable connector 321, and other circuit components connected to the positive cable connector 311 and the negative cable connector 321. The signal of the signal pin 8 will also transmit a signal to the low-speed signal line in the bottom printed circuit board 9 through the circuit connection device. At this time, a method of separating the power supply from the low-speed signal of the power connection device is formed. The current does not flow through the bottom printed circuit board 9, so huge heat will not be generated on the bottom printed circuit board 9. The reduction of heat on the bottom printed circuit board 9 can reduce the interference of heat on the low-speed signal transmission on the bottom printed circuit board 9. At the same time, the reduction of heat on the bottom printed circuit board 9 will also reduce the impact on the control and monitoring system of the server system on the power connector. Since the cable connector on the bottom printed circuit board 9 is transferred above the power connection device, the usable area on the bottom printed circuit board 9 is reduced, and thus the package area of the power connection device is reduced.
[0067] Embodiment 2
[0068] In Embodiment 2 of the present invention, a server is proposed, which includes a power connection device described above, and the network interface of the server is arranged on the power connection device.
[0069] As Figure 1 、 Figure 2 、 Figure 3 shown, it can be understood that the network interface of the server and the power connection device are pluggable connections. When the power supply module is inserted into multiple positive pins 4, multiple negative pins 5, and signal pin 8 of the power connection device, the positive and negative currents will pass through multiple positive pins 4 and multiple negative pins 5 to conduct to the top printed circuit board 1. The current conducted to the top printed circuit board 1 will pass through the top printed circuit board 1 to conduct to the positive cable connector 311, the negative cable connector 321, and other circuit components connected to the positive cable connector 311 and the negative cable connector 321, completing the power supply process of the power supply module to the power connection device and other circuit components.
[0070] When the current of the power supply module passes through the power connection device, the signal pin 8 will emit a low-speed signal. Since the signal pin 8 is connected to the bottom printed circuit board 9 through the via hole 91, the low-speed signal emitted by the signal pin 8 will also transmit the low-speed signal to the low-speed signal line in the bottom printed circuit board 9 through the circuit connection device. Since the network cable interface of the server is set on the power connection device, after the low-speed signal emitted by the signal pin 8 in the power connection device is transmitted through the low-speed signal line in the bottom printed circuit board 9, the low-speed signal emitted by the signal pin 8 in the power connection device will be transmitted to the server connected to the power connection device. At this time, the signal transmission of the low-speed signal emitted by the signal pin 8 in the power connection device is completed.
[0071] In this embodiment, the server system further includes a power supply module.
[0072] It can be understood that the power supply module can also be an external power supply device. The power supply module can be inserted into the multiple positive pins 4, multiple negative pins 5, and multiple signal pins 8 of the power connection device. Since the power supply module is inserted into the multiple positive pins 4, multiple negative pins 5, and multiple signal pins 8 of the power connection device, the multiple positive pins 4 are further connected to the positive connection holes 11 in the top printed circuit board 1 for circuit conduction, and the multiple negative pins 5 are further connected to the negative connection holes 12 in the top printed circuit board 1 for circuit conduction. At the same time, the positive connection holes 11 in the top printed circuit board 1 are further connected to the positive cable connector 311 for circuit conduction, and the negative connection holes 12 in the top printed circuit board 1 are further connected to the negative cable connector 321 for circuit conduction. At this time, the current of the power supply module passes through the multiple positive pins 4 and multiple negative pins 5 of the power connection device and flows to the positive connection holes 11 and negative connection holes 12 on the top printed circuit board 1. The current then passes through the positive connection holes 11 and negative connection holes 12 on the top printed circuit board 1 and flows to the positive cable connector 311 and negative cable connector 321. After the positive cable connector 311 and negative cable connector 321 are connected to the cable connector, the current will flow to the cable connector. When the cable connector is electrically connected to other circuit elements through the power cable, the current of the power supply module can pass through the power cable and flow to other circuit elements to directly supply power to other circuit elements, completing the entire power supply process.
[0073] During the entire power supply process, the current output by the power module and the current input to the power module through the power connection device only flow through the interior of the power connection device and do not flow through the bottom printed circuit board 9 outside the power connection device. At this time, the current of the power module is separated from the low-speed signals in the bottom printed circuit board 9. Since the current does not flow through the bottom printed circuit board 9, a large amount of heat will not be generated on the bottom printed circuit board 9. The reduction of heat on the bottom printed circuit board 9 can reduce the interference of heat on the transmission of low-speed signals on the bottom printed circuit board 9. At the same time, the reduction of heat on the bottom printed circuit board 9 will also reduce the impact on the control and monitoring systems of the server system for the power connector. Since the cable connectors on the bottom printed circuit board 9 are transferred above the power connection device, the usable area of the bottom printed circuit board 9 is reduced, thus reducing the package area of the power connection device.
[0074] It can be understood that when the current of the power module passes through the power connection device, the signal pins 8 in the power connection device will transmit signals to the bottom printed circuit board 9 through the vias 91, and the low-speed signal lines in the bottom printed circuit board 9 are used to transmit the signals sent by the signal pins 8. In this way, when the current of the power module passes through the power connection device, the positive and negative currents will be conducted to the top printed circuit board 1 through multiple positive pins 4 and multiple negative pins 5 to supply power to the positive cable connector 311, the negative cable connector 321, and other circuit components connected to the positive cable connector 311 and the negative cable connector 321. The signals of the signal pins 8 will also transmit signals to the low-speed signal lines in the bottom printed circuit board 9 through the circuit connection device. At this time, a method of separating the power supply from the low-speed signals of the power connection device is formed. Since the current does not flow through the bottom printed circuit board 9, a large amount of heat will not be generated on the bottom printed circuit board 9. The reduction of heat on the bottom printed circuit board 9 can reduce the interference of heat on the transmission of low-speed signals on the bottom printed circuit board 9. At the same time, the reduction of heat on the bottom printed circuit board 9 will also reduce the impact on the control and monitoring systems of the server system for the power connector. Since the cable connectors on the bottom printed circuit board 9 are transferred above the power connection device, the usable area of the bottom printed circuit board 9 is reduced, thus reducing the package area of the power connection device.
[0075] The present invention provides a power connection device and a server. By arranging the positive cable connector and the negative cable connector on the top of the power connection device, then electrically connecting a plurality of positive pins to the positive cable connector through the top printed circuit board, and electrically connecting a plurality of negative pins to the negative cable connector through the top printed circuit board, and then electrically connecting a plurality of signal pins to the bottom printed circuit board provided with low-speed signal lines. At this time, the positive and negative power cable connectors are transferred to the top of the power connection device. The positive and negative power cable connectors on the top of the power connection device can directly supply power to the corresponding components inside the server. At the same time, the low-speed signal connection of the power connection device is arranged on the bottom printed circuit board, thus forming a way to separate the power from the low-speed signal of the power connection device. Therefore, the positive and negative cable connectors that generate a large amount of heat are connected from the top of the power connection device to the top printed circuit board, effectively avoiding the generation of huge heat on the bottom printed circuit board and not interfering with the transmission of low-speed signals and affecting the control and monitoring of the power connector by the server system. Moreover, it can also reduce the area of the bottom printed circuit board.
