[0017] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0018] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0019] Figure 1 An exemplary structure 100 is shown to which the connector of the present disclosure may be applied.

[0020] like Figure 1 As shown, the connector 100 includes: an output end 101, the output end includes an output ground pin and a plurality of pairs of output power supply pins; an input end 102, the input end includes a plurality of input pin groups corresponding one-to-one to the plurality of pairs of output power supply pins, each pair of output power supply pins is connected to a pair of input power supply pins in a corresponding input pin group, and the output ground pin is connected to input ground pins in a plurality of input pin groups; the plurality of input pin groups correspond one-to-one to a plurality of power lines, a pair of input power supply pins in each input pin group is used to connect a pair of power supply sub-wires in a corresponding power line, and an input ground pin in each input pin group is used to connect a grounding sub-wire in a corresponding power line.

[0021] The output end is an electric energy output end, which is used to connect to the electric energy input interface of the server cabinet, such as a plug-in connector. The input end is an electric energy input end, which is used to connect to a power line that provides electric energy.

[0022] The output end includes an output ground pin and multiple pairs of output power supply pins, each pair of output power supply pins includes two output power supply pins. The input end includes multiple input pin groups corresponding to the multiple pairs of output power supply pins, each input pin group includes a pair of input power supply pins and an input ground pin, and two input power supply pins in a pair of input power supply pins are connected to two output power supply pins in a corresponding pair of output power supply pins in a one-to-one correspondence. The output ground pin in the output end is connected to each input ground pin in the input end.

[0023] According to different power supply modes, the number of pairs of output power supply pins and the number of input pin groups in the connector are different. For example, the number of pairs of output power supply pins and the number of input pin groups are three.

[0024] Each input pin group in the input end can be specifically expressed as a connector, and multiple connectors are connected to multiple power lines in a one-to-one correspondence. Each power line includes three sub-lines, namely a grounding sub-line and two sub-lines in a power supply line pair, and the two sub-lines cooperate with each other to realize the power supply function. Two input power supply pins in a pair of input power supply pins in a connector are used to connect the two sub-lines in the power supply line pair in the corresponding one power line, and the input ground pin is used to connect the ground sub-line in the corresponding one power line.

[0025] In this way, the connector can merge multiple sub-wires in a multi-way power cord into multiple pins corresponding to the output end (output end ground pins and multiple pairs of output end power supply pins) to output electrical energy to adapt to the server cabinet, thereby adapting the multi-way power cord to the power supply method of the server cabinet, reducing the difficulty of power supply deployment of the entire server cabinet, and improving the compatibility of the entire server cabinet in various power supply scenarios.

[0026] In some optional implementations of this embodiment, the multi-channel power lines are multi-channel AC power lines, and the power line pair includes a phase line and a neutral line.

[0027] Phase lines, also known as live wires, are lines with voltage in a circuit. In power transmission, the electrical energy output by a power plant is transmitted via phase lines. In a three-phase circuit, the angle between each phase line is 120°, and the voltage between them is 380V. Phase lines are key lines for the normal operation of electrical equipment because they provide the required electrical energy.

[0028] The neutral line, also known as the zero line, is a line without voltage in the circuit. In a three-phase circuit, the three phase lines have a common intersection point, which is called the "neutral point". The line drawn from the neutral point is the neutral line. The neutral line plays an important role in the circuit in carrying unbalanced current, participating in the formation of the loop and providing safety protection.

[0029] In this implementation, each AC power line includes three sub-lines, namely, a phase line, a neutral line, and a grounding line.

[0030] In this implementation, a pair of input-end power supply pins in each input-end pin group is used to connect the phase line and the neutral line in a corresponding AC power line. Specifically, for each input-end pin group, one of the pair of input-end power supply pins in the input-end pin group is connected to the phase line in the AC power line corresponding to the input-end pin group, and the other input-end power supply pin is connected to the neutral line in the AC power line corresponding to the input-end pin group.

[0031] In this implementation, a connection method between a connector and a power cord under AC power supply is provided, and the connector makes the server cabinet suitable for power supply scenarios with multiple AC power cords.

[0032] Continue to refer Figure 2 , showing a schematic diagram of the internal connection relationship of the connector to which the present disclosure can be applied.

[0033] In some optional implementations of this embodiment, the multiple pairs of output power supply pins include a first pair of output power supply pins, a second pair of output power supply pins, and a third pair of output power supply pins, and the multiple input pin groups include a first pin group, a second pin group, and a third pin group. Each input pin group includes a phase line pin, a neutral line pin, and an input ground pin.

[0034] In this implementation, the pin connection relationship between the output end and the input end of the connector is as follows:

[0035] A first pin 1011 of the first pair of output-end power supply pins is connected to a first phase line pin 1021 of a pair of input-end power supply pins in the first pin group;

[0036] The second pin 1012 of the first pair of output-end power supply pins is connected to the first neutral line pin 1022 of the pair of input-end power supply pins in the first pin group;

[0037] A third pin 1013 of the second pair of output-end power supply pins is connected to a second phase line pin 1023 of a pair of input-end power supply pins in the second pin group;

[0038] The fifth pin 1015 of the second pair of output-end power supply pins is connected to the second neutral line pin 1024 of the pair of input-end power supply pins in the second pin group;

[0039] A sixth pin 1016 of the third pair of output-end power supply pins is connected to a third phase line pin 1025 of a pair of input-end power supply pins in the third pin group;

[0040] The seventh pin 1017 of the third pair of output-end power supply pins is connected to the third neutral line pin 1026 of the pair of input-end power supply pins in the third pin group;

[0041] The fourth pin 1014 serving as an output terminal ground pin is connected to the input terminal ground pins 1027 , 1028 , 1029 of the first pin group, the second pin group, and the third pin group, respectively.

[0042] In this implementation, when powered by three AC power sources, a specific connection relationship inside the connector is provided, and the nine cores (nine sub-wires) of the three AC power sources can be combined into 7Pins (first pin 1011 to seventh pin 1017) to adapt to the 7Pin power supply method of the server cabinet, thereby improving the practicality and reliability of the connector when powered by three AC power sources.

[0043] In some optional implementations of this embodiment, the phase line pins in each pair of input power supply pins are used to connect the phase line in the corresponding AC power line, and the neutral line pins in each pair of input power supply pins are used to connect the neutral line in the corresponding AC power line.

[0044] In this implementation, each pair of input power supply pins includes a phase line pin and a neutral line pin, the phase line pin is used to connect the phase line in the corresponding AC power line, and the neutral line pin is used to connect the neutral line in the corresponding AC power line.

[0045] In this implementation, a connection relationship between the input end of the connector and the multi-channel AC power lines is provided, thereby improving the connection convenience between the connector and the power lines.

[0046] Continue to refer Figure 3 , showing a schematic diagram of the connection relationship between the input end of the connector and the three-way AC power lines.

[0047] In some optional implementations of this embodiment, the multi-channel AC power line 103 includes a first AC power line 1031 , a second AC power line 1032 , and a third AC power line 1033 .

[0048] In this implementation, the connection relationship between the input end of the connector and the three-way AC power cord is as follows:

[0049] The first phase line pin is used to connect the phase line in the first AC power line; the first neutral line pin is used to connect the neutral line in the first AC power line; the second phase line pin is used to connect the phase line in the second AC power line; the second neutral line pin is used to connect the neutral line in the second AC power line; the third phase line pin is used to connect the phase line in the third AC power line; the third neutral line pin is used to connect the neutral line in the third AC power line; the input ground pins of the first pin group, the second pin group, and the third pin group are respectively used to be connected one-to-one with the grounding sub-wires of the first AC power line, the second AC power line, and the third AC power line.

[0050] In the case of three-way AC power supply, the first pin to the seventh pin (Pin1-Pin7) of the 7-pin connector of the server cabinet are connected one-to-one with the first pin to the seventh pin of the output end of the connector, and the three pin groups at the input end are connected one-to-one with the three-way AC power lines.

[0051] Continue to refer Figure 4 , showing the connection relationship between the 7-pin connector and the three-way AC power cord.

[0052] Specifically, the connection relationship between the 7-pin connector and the three-way AC power cord is as follows:

[0053] The first pin in the connector is used to connect the phase line in the first AC power line, and the second pin in the connector is used to connect the neutral line in the first AC power line; the third pin in the connector is used to connect the phase line in the second AC power line, and the fifth pin in the connector is used to connect the neutral line in the second AC power line; the sixth pin in the connector is used to connect the phase line in the sixth AC power line, and the seventh pin in the connector is used to connect the neutral line in the third AC power line; the grounding pin in the connector serves as the fourth pin in the connector, and is used to connect the grounding sub-line in the first AC power line, the grounding sub-line in the second AC power line, and the grounding sub-line in the third AC power line.

[0054] In this implementation, a connection relationship between the input end of the connector and the three-way AC power lines is provided when a three-way AC power supply is provided. The three-way AC power lines are connected to the three pin groups in a one-to-one correspondence, thereby improving the convenience of the connector.

[0055] In some optional implementations of this embodiment, the multiple power lines are multiple DC power lines, and the power line pair includes a positive line and a negative line.

[0056] In a DC circuit, the positive line is where the current flows out and where the voltage is above zero potential. In a DC circuit, current always flows from the positive pole to the negative pole. The positive line is a key part that connects the positive pole of the power supply to the circuit, ensuring that the current can flow smoothly from the power supply to the server cabinet.

[0057] The negative wire is where the current enters the power supply and where the voltage is below zero potential. In a DC circuit, electrons flow out of the negative electrode and back through the circuit to the positive electrode. The main function of the negative wire is to connect the negative electrode of the power supply to the circuit to ensure that the current can flow smoothly back to the power supply.

[0058] In this implementation, each DC power line includes three sub-lines, namely a positive line, a negative line and a grounding sub-line.

[0059] In this implementation, a pair of input-end power supply pins in each input-end pin group is used to connect the positive line and the negative line in a corresponding DC power line. Specifically, for each input-end pin group, one of the pair of input-end power supply pins in the input-end pin group is connected to the positive line in the DC power line corresponding to the input-end pin group, and the other input-end power supply pin is connected to the negative line in the DC power line corresponding to the input-end pin group.

[0070] The fourth pin 1014 serving as an output terminal ground pin is connected to the input terminal ground pins 1027 , 1028 , 1029 of the first pin group, the second pin group, and the third pin group, respectively.

[0071] In this implementation, when powered by three DC power supplies, a specific connection relationship inside the connector is provided, and the nine cores (nine sub-wires) of the three DC power supplies can be combined into 7Pins (first pin 1011 to seventh pin 1017) to adapt to the 7Pin power supply method of the server cabinet, thereby improving the practicality and reliability of the connector when powered by three DC power supplies.

The three DC power lines are connected to the three pin groups in a one-to-one correspondence, thereby improving the convenience of the connector.

[0084] Inside the server cabinet, each PSU (Power Supply Unit) module is essentially still a single-phase power module, and the power distribution inside the cabinet is achieved by the power frame of the PSU.

[0085] Continue to refer Figure 8 , showing a schematic diagram of the connection relationship of the power supply system of the server cabinet.

[0086] like Figure 8 As shown, the power supply system 200 of the server cabinet includes: a server cabinet 201; a connector 202, and the connector on the server cabinet is connected to multiple power lines through the connector.

[0087] The connecting piece is the connecting piece described in any implementation method in the above-mentioned embodiment 100.

[0088] Specifically, a plug-in connector is provided on the server cabinet, the plug-in connector is connected to the output end of the connector, and the input end of the connector is connected to multiple power lines.

[0089] In some optional implementations of this embodiment, two plug-ins are provided on the server cabinet. The two plug-ins are redundantly provided to improve the power supply reliability of the server cabinet.

[0090] In this implementation, each connector is connected to multiple AC power lines via a corresponding connector, wherein the connection relationship between the connector and the multiple AC power lines is as shown in the implementation of the above embodiment 100, and will not be repeated here.

[0091] In this implementation, each connector can receive AC power through a connector suitable for AC power supply situations, thereby ensuring power supply reliability and improving the adaptability of the server cabinet under AC power supply situations.

[0092] In some optional implementations of this embodiment, two plug-ins are provided on the server cabinet. The two plug-ins are redundantly provided to improve the power supply reliability of the server cabinet.

[0101] Based on the connector, the power supply system of the server cabinet has outstanding effects in full-scenario compatibility and future elastic compatibility. Specifically, in terms of full-scenario compatibility, whether it is a computer room with dual UPS (Uninterruptible Power Supply), dual HVDC, dual AC power, or one AC power and one HVDC power supply, the server cabinet can be powered by the connector.

[0102] In terms of future flexibility and compatibility, data centers may need to increase cabinet power density at any time during future operations. When the AC voltage is too low and a single cabinet cannot withstand excessively high cable density, the HVDC supply voltage level can be increased. Under the dual-channel HVDC solution, the above-mentioned 9-sub-line to 7-pin power supply solution based on connectors is still applicable.
