[0058] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0059] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0060] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0061] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0062] In order to make the cabinet wiring neat and orderly, a rack power distribution unit (rPDU) is usually installed in the cabinet. Figure 1a As shown in the figure, rPDU is designed to provide power distribution for equipment installed in the cabinet. It has a variety of series specifications with different functions, installation methods and different socket combinations. It can provide suitable rack-mounted power distribution solutions for different power supply environments, reduce the amount of wiring, and make the power distribution in the cabinet more neat, reliable, safe, professional and beautiful, and make the maintenance of the power supply in the cabinet more convenient and reliable.

[0063] However, due to different application scenarios of the cabinet, the type of interface for powering the cabinet may be a single-phase electrical interface or a three-phase electrical interface. In order to match different types of power supply interfaces, different types of rPDUs need to be set up in the cabinet. For example, a single-phase rPDU or a three-phase rPDU is used for adaptation. Figure 1b and Figure 1c As shown, the types of rPDUs in different cabinets are different, which makes the cabinets difficult to manage and hand over, and the cabinets difficult to maintain, thereby reducing the efficiency of cabinet maintenance.

[0064] In view of the above problems, an embodiment of the present application provides a power distribution component, which includes a power distribution module and a conversion module. The power distribution module includes n pairs of first power terminals, and each pair of first power terminals includes a first phase line terminal and a first neutral line terminal. The power distribution module is used to simultaneously receive n groups of x-phase electrical signals and output n groups of x-phase electrical signals through n pairs of first power terminals, and is also used to receive m groups of x-phase electrical signals and output m groups of x-phase electrical signals through m pairs of first power terminals. The conversion module includes an input end and a connection end. The connection end is electrically connected to the first phase line terminal and the first neutral line terminal of the k pairs of first power terminals in the power distribution module. The conversion module is used to receive a y-phase electrical signal through the input end, convert the y-phase electrical signal into h groups of x-phase electrical signals, and output them to the power distribution module through the connection end. In this way, the received y-phase electrical signal can be converted into h groups of x-phase electrical signals through the conversion module, and the h groups of x-phase electrical signals can be transmitted to the power distribution module through the conversion end. The power distribution module can not only receive m groups of x-phase electrical signals and output m groups of x-direction electrical signals through m pairs of first power terminals, but also receive n groups of x-terminal electrical signals and output n groups of x-direction electrical signals through n pairs of first power terminals. That is, in the embodiment of the present application, the power distribution component can convert the y-phase electrical signal into an x-phase electrical signal through a conversion module, wherein y can be different from x, and output through the power distribution module, so as to realize the conversion of different types of electrical signals into x-phase electrical signals. In other words, the power distribution component in the present application can be applicable to different types of power supply interfaces, and after receiving different types of phase electrical signals from different types of power supply interfaces, it can be converted into an x-phase electrical signal and then output. In this way, when it is applied to a cabinet, the power distribution components used in different cabinets can be the same, which greatly reduces the difficulty of cabinet management and handover, and improves the maintenance efficiency of the cabinet. The following is a detailed description.

[0065] See also Figure 2 , is a schematic diagram of the structure of a power distribution component provided in an embodiment of the present application. Figure 2 As shown, the power distribution components include:

[0066] The power distribution module 10 includes n pairs of first power terminals 11, each pair of first power terminals 11 includes a first phase terminal 111 and a first neutral terminal 112. The power distribution module 10 is used to simultaneously receive n groups of x-phase electrical signals through the n pairs of first power terminals 11 and output n groups of x-phase electrical signals, and is also used to receive m groups of x-phase electrical signals through m pairs of first power terminals and output m groups of x-phase electrical signals.

[0067] Wherein, n is an integer greater than m and not less than 2, m is an integer greater than 0, and x is an integer greater than 0.

[0068] The conversion module 20 includes an input terminal 21 and a connection terminal 22, and the connection terminal 22 is electrically connected to the first phase line terminal 111 and the first neutral line terminal 112 of the k pairs of first power terminals 11. The conversion module 20 is used to receive the y-phase electrical signal through the input terminal 21, convert the y-phase electrical signal into h groups of x-phase electrical signals, and output them to the power distribution module 10 through the connection terminal 22.

[0069] Herein, k is an integer greater than 0 and not greater than n, y is an integer not less than x, and h is an integer greater than 0, not greater than k, and not greater than y.

[0070] In an embodiment of the present application, the power distribution component includes a power distribution module 10 and a conversion module 20. The power distribution module 10 includes n pairs of first power terminals 11, and each pair of first power terminals 11 includes a first phase line terminal 11 and a first neutral line terminal 112. The n pairs of first power terminals 11 in the power distribution module 10 can receive and output no more than n groups of x-phase electrical signals. That is, the power distribution module 10 can simultaneously receive and output n groups of x-phase electrical signals, or can receive and output m groups of x-phase electrical signals. Among them, m is an integer greater than 0. n is an integer greater than 2 and greater than m. x refers to the number of phases of the electrical signal, and x is an integer greater than 0.

[0071] The conversion module 20 includes an input terminal 21 and a connection terminal 22. The connection terminal 22 is electrically connected to the k pairs of first power terminals 11 in the power distribution module 10. That is, the connection terminal 22 is electrically connected to the first phase line terminal 111 and the first neutral line terminal 112 in the k pairs of first power terminals 11. The input terminal 21 of the conversion module 20 is used for an external y-phase power supply. After the input terminal 21 of the conversion module 20 receives the y-phase electrical signal, the y-phase electrical signal can be converted into h groups of x-phase electrical signals, and the h groups of x-phase electrical signals are transmitted to the h pairs of first power terminals 11 in the power distribution module 10 through the connection terminal 22. Each pair of the h pairs of first power terminals 11 in the power distribution module 10 receives a group of x-phase electrical signals and can output the received x-phase electrical signals. Wherein, h is an integer greater than 0 and not greater than k. k is an integer greater than 0 and not greater than n. That is, k may be n, h may be n, at this time, the power distribution module 10

[0072] H groups of x-phase electrical signals are converted from y-phase electrical signals, so the h groups of x-phase electrical signals are independent of each other. In this way, the h pairs of first power terminals 11 in the power distribution module 10 receive a group of x-phase electrical signals respectively, that is, the power distribution module 10 receives h groups of x-phase electrical signals, and the h groups of x-phase electrical signals are independent of each other. The h groups of x-phase electrical signals output by the power distribution module 10 are also independent of each other. It does not receive a group of x-phase electrical signals and divide a group of x-phase electrical signals into h groups for output.

[0073] The value of y is related to the power supply connected to the input end of the conversion module 20. Since the power supply connected to the input end of the conversion module 20 may be a three-phase power supply or a single-phase power supply. Therefore, in some embodiments, when the power supply connected to the input end of the conversion module 20 is a three-phase power supply, the value of y is 3. In some embodiments, when the power supply connected to the input end of the conversion module 20 is a single-phase power supply, the value of y is 1. Of course, the power supply connected to the input end of the conversion module 20 may also be other phase power supplies, in which case the value of y is the corresponding number of phases, which is not limited in this application.

[0074] The value of x is related to the power supply required by the load that the power distribution module 10 needs to be connected to. In some embodiments, when the power supply required by the load that the power distribution module 10 needs to be connected to is a single-phase power supply, the value of x is 1. At this time, the conversion module 20 needs to convert the external y-phase electrical signal into a single-phase electrical signal. That is, after receiving the y-phase electrical signal, the conversion module 20 can convert the y-phase electrical signal into h groups of single-phase electrical signals, and transmit the h groups of single-phase electrical signals to the h pairs of first power terminals 11 in the power distribution module 10, and each pair of first power terminals 11 in the h pairs of first power terminals 11 can receive a group of single-phase electrical signals, and each pair of first power terminals 11 can output a single-phase electrical signal to the load when the load is connected to the external load. At this time, the value of h is equal to the value of y. That is, the y-phase electrical signal can be converted into y groups of single-phase electrical signals, and y groups of single-phase electrical signals can be output to the power distribution module 10. When the value of x is 1, each pair of first power terminals 11 in the power distribution module 10 needs to receive a single electrical signal. Therefore, each pair of power terminals 11 includes a first phase terminal 111 and a first neutral terminal 112 .

[0075] It should be understood that since the x-phase electrical signal is an electrical signal output by the power distribution module 10 to the external load, when the power supply required by the load connected to the power distribution module 10 is a power supply of other phases, the value of x also needs to change accordingly. That is, the value of x is the number of phases of the power supply required by the load. For example, when the power supply required by the load connected to the power distribution module 10 is a two-phase power supply, the value of x is 2. At this time, the conversion module 20 needs to convert the received y-phase electrical signal into h groups of 2-phase electrical signals. Each pair of the h pairs of first power terminals 11 in the power distribution module 10 receives a group of 2-phase electrical signals, and the 2-phase electrical signals received by different pairs of first power terminals 11 are different. Each pair of first power terminals 11 may include two first phase line terminals 111 and a first neutral line terminal 112, or may include two first phase line terminals 111 and a first neutral line terminal 112. At this time, the two first phase line terminals 111 share a first neutral line terminal 112, and the first neutral line terminals 112 in different first power terminals 11 are different. In order to better be compatible with other phase electrical signals, the number of first phase terminals 111 and first neutral terminals 112 included in each pair of first power terminals 11 is the same. That is, each pair of first power terminals 11 may include at least one first phase terminal 111 and at least one first neutral terminal 112, and each first phase terminal 111 has a corresponding first neutral terminal 112.

[0076] In this way, through the above-mentioned power distribution components, the conversion module 20 can convert the received y-phase electrical signal into h groups of x-phase electrical signals, and transmit them to the h pairs of first power terminals 11 of the power distribution module 10. Each pair of the h pairs of first power terminals 11 of the power distribution module 10 can output the x-phase electrical signal after receiving a group of x-phase electrical signals. That is, in the embodiment of the present application, the power distribution component can receive different-phase electrical signals, and convert the received different-phase electrical signals into x-phase electrical signal outputs, which is suitable for different types of power interfaces, and there is no need to adapt different types of power distribution components for different types of power interfaces. In this way, when it is applied to a cabinet, the power distribution components used in different cabinets can be the same, which greatly reduces the difficulty of cabinet management and handover, and improves the maintenance efficiency of the cabinet.

[0077] As a possible implementation method, in order to increase the safety of the power distribution components, such as Figure 3 As shown, the power distribution module 10 further includes a first ground terminal 12, and the conversion module 20 further includes a second ground terminal 23. The first ground terminal 12 is electrically connected to the second ground terminal 23.

[0078] As a possible implementation, the conversion module 20 can convert the received y-phase electrical signal into an x-phase electrical signal through the input terminal 21 and the connection terminal 22 by setting a plurality of neutral terminals in the connection terminal 22. At this time, the conversion module 20 includes a first connector 201. In order to satisfy that the first connector 201 itself can convert the received y-phase electrical signal into an x-phase electrical signal, the structure of the first connector 201 is different from the existing connector structure.

[0079] like Figure 4 As shown, the first connector 201 includes a first input terminal 211 and a first connection terminal 221, the first input terminal 211 includes a first neutral line input terminal 2111 and k first phase line input terminals 2112; the first connection terminal 221 includes k pairs of second power terminals 2211, and each pair of second power terminals 2211 includes a second phase line terminal 22111 and a second neutral line terminal 22112.

[0080] The first ends of the second phase terminals 22111 in the k pairs of second power terminals 2211 are electrically connected to the k first phase input terminals 2112, and the first ends of different second phase terminals 22111 are electrically connected to different first phase input terminals 2112; the first ends of the second zero terminals 22112 in the k pairs of second power terminals 2211 are electrically connected to the first zero input terminal 2111. The second ends of the second phase terminals 22111 in the k pairs of second power terminals 2211 are electrically connected to the first phase terminals 111 in the k pairs of first power terminals 11, and the second ends of different second phase terminals 22111 are electrically connected to different first phase terminals 111; the second ends of the second zero terminals 22112 in the k pairs of second power terminals 2211 are electrically connected to the first zero terminals 112 in the k pairs of first power terminals 11, and the second ends of different second zero terminals 22112 are electrically connected to different first zero terminals 112.

[0081] The first connector 201 is used to receive the y-phase electrical signal through the first input terminal 211 , convert the y-phase electrical signal into h groups of x-phase electrical signals, and output the h groups of x-phase electrical signals to the power distribution module 10 through h pairs of second power terminals 2211 .

[0082] That is, the conversion module 20 in the embodiment of the present application can be implemented by the first connector 201. At this time, the first connector 201 includes a first input terminal 211 and a first connection terminal 221. The first input terminal 211 of the first connector 201 is the input terminal 21 in the conversion module 20, and the first connection terminal 221 is the connection terminal 22 in the conversion module 20. The first input terminal 211 includes a first zero line input terminal 2111 and k first phase line input terminals 2112. The first connection terminal 221 includes k pairs of second power supply terminals 2211, and each pair of second power supply terminals 2211 includes a second phase line terminal 22111 and a second zero line terminal 22112. That is, the first connection terminal 221 includes k second phase line terminals 22111 and k second zero line terminals 22112. The first ends of the k second zero line terminals 22112 are all electrically connected to the first zero line input terminal 2111. The first ends of the k second phase terminals 22111 are respectively electrically connected to the k first phase input terminals 2112. In this way, when the first connector 201 is connected to an external power source, it receives a y-phase electrical signal through the first neutral input terminal and the k first phase input terminals, and transmits the received y-phase electrical signal to the first connection terminal 221. The second ends of the second phase terminals 22111 in the first connection terminal 221 are respectively electrically connected to the first phase terminals 111 in the k first power terminals 11, and different second phase terminals 22111 are electrically connected to different first phase terminals 111, and the second ends of the k second neutral terminals 22112 are respectively electrically connected to the first neutral terminals 112 in the k first power terminals 11, and different second neutral terminals 22112 are electrically connected to different first neutral terminals 112. In this way, the first connection end 221 in the first connector 201 can convert the received y-phase electrical signal into h groups of x-item electrical signals, and transmit the h groups of x-item electrical signals to the power distribution module 10 through h pairs of second power terminals 2211. h is an integer greater than 0 and not greater than k, and k is an integer greater than 0 and not greater than n, that is, h is not greater than n.

[0083] The power distribution component transmits the external power supply to the external load. When the electrical signal required by the external load is different from the external power supply of the power distribution component, the power distribution component needs to convert the external power supply into the power signal required by the external load. At this time, the first connector 201 needs to convert the electrical signal. When the electrical signal required by the external load is the same as the external power supply of the power distribution component, the electrical signal can be transmitted directly. At this time, the first connector 201 does not need to convert the electrical signal. Based on this, in the power distribution component, the structure of the first connector 201 is different depending on whether the external power supply is the same as the power required by the load.

[0084] When the electrical signals required by the external power supply and the load are different, that is, the values ​​of y and x are different, as a possible implementation, the first input terminal 211 of the first connector 201 includes a first neutral line input terminal 2111 and k first phase line input terminals 2112.

[0085] The first ends of the second phase terminals 22111 in the k pairs of second power terminals 2211 are electrically connected to k first phase input terminals 2112, respectively, and the first ends of different second phase terminals 22111 are electrically connected to different first phase input terminals 2112. The first ends of the second neutral terminals 22112 in the k pairs of second power terminals 2211 are all electrically connected to the one first neutral input terminal 2111.

[0086] Normally, the power source external to the power distribution component can be a single-phase electrical signal or a multi-phase electrical signal, and the number of phases of the external power source is greater than or equal to the number of phases of the electrical signal required by the load. And normally, the external power source usually only contains one neutral line. That is, when the external power source is a multi-phase electrical signal, multiple phase lines share one neutral line. Based on this, in an embodiment of the present application, in order to facilitate electrical connection with an external power source, the first input terminal 211 of the first connector 201 includes a first neutral line input terminal 2111 and k first phase line input terminals 2112. Since the first input terminal 211 needs to be electrically connected to the first connection terminal 221, the first ends of the second phase line terminals 22111 of the k pairs of second power terminals 2211 in the first connection terminal 221 are respectively electrically connected to the k first phase line input terminals 2112, and the first ends of the second neutral line terminals 22112 of the k pairs of second power terminals 2211 are all electrically connected to the first neutral line input terminal 2111 in the first input terminal 211, such as Figure 5As shown, the y-phase electrical signal is converted into h groups of x-phase electrical signals. That is, in the circuit, the phase line is usually electrically connected to the phase line, and the neutral line is electrically connected to the neutral line. Based on this, in order to electrically connect the k pairs of first power terminals 11 in the power distribution module 10 in a one-to-one correspondence in the first connection end 221, the first connection end 221 includes k pairs of second power terminals 2211. Each second power terminal 2211 includes a second phase line terminal 22111 and a second neutral line terminal 22112. The second end of the second phase line terminal 22111 in each second power terminal 2211 is electrically connected to the first phase line terminal 111 in the first power terminal 11 corresponding to it. The second end of the second neutral line terminal 22112 in each second power terminal 2211 is electrically connected to the first neutral line terminal 112 in the first power terminal 11 corresponding to it. Furthermore, the first input terminal 211 needs to be electrically connected to the first connection terminal 221, and the first input terminal 211 includes k first phase line input terminals 2112 and one neutral line input terminal 2111, so the second phase line terminals 22111 of the k pairs of second power supply terminals 2211 of the first connection terminal 221 are electrically connected to the k first phase line input terminals 2112 in a one-to-one correspondence. The second neutral line terminals 22112 of the k pairs of second power supply terminals 2211 in the first connection terminal 221 are all electrically connected to the first neutral line input terminal 2111. That is to say, in the power distribution component, an external power supply is connected through the first input terminal 211 in the first connector 201. At this time, part or all of the k first phase line input terminals 2112 of the first input terminal 211 are electrically connected to the phase lines in the external power supply in a one-to-one correspondence, and a neutral line input terminal 2111 of the first input terminal 211 is electrically connected to a neutral line in the external power supply. The first input terminal 211 divides the neutral line input terminal 2111 into k second neutral line terminals 22112 through the first connection terminal 221. In this way, when the first input terminal 211 receives y electrical signals, since the first connection terminal 221 contains k second neutral line terminals 22112, the received y-phase electrical signals can be divided into h groups of x-phase electrical signals through h pairs of second power terminals 2211 at the first connection terminal 221 and transmitted to the first power terminal 111 in the power distribution module 10.

[0087] In some possible implementations, the number k of the first phase line input terminals 2112 in the first connector 201 is the same as the number of phases of the external power supply, so that the first connector 201 can be electrically connected to the external power supply to receive electrical signals.

[0088] For example, it is assumed that the external power supply in the power distribution component is a three-phase power supply, and the electrical signal required by the external load is a single-phase electrical signal. Figure 6a and Figure 6bAs shown, the power distribution assembly includes a power distribution module 10 and a first connector 201. The first connector 201 includes a first neutral line input terminal 2111 and three first phase line input terminals 2112. The three first phase line input terminals 2112 are electrically connected to the first ends of the second phase line terminals 22111 in the three pairs of second power terminals 2211 in the first connection terminal 221, and the first ends of the second neutral line terminals 22112 in the three pairs of second power terminals 2211 are all electrically connected to the first neutral line input terminal 2111, as shown in FIG. Figure 6c As shown. In this way, when the first connector 201 is connected to an external 3-phase power supply, the three phase lines in the external 3-phase power supply usually share a neutral line. Therefore, the three first phase line input terminals 2112 of the first connector 201 are electrically connected to the three phase lines in the external 3-phase power supply, and the first neutral line input terminal 2111 is electrically connected to the neutral line in the external 3-phase power supply. After the first input terminal 211 of the first connector 201 receives the three-phase electrical signal, when the three-phase electrical signal is transmitted to the first connection terminal 221, since the first connection terminal 221 includes three second neutral line terminals 22112, the first connection terminal 221 can directly convert the three-phase electrical signal into three single-phase electrical signals, and transmit the three single-phase electrical signals to the three pairs of first power terminals 11 in the power distribution module 10 through the three pairs of second power terminals 2211, so as to be transmitted to the external load through the first power terminals 11.

[0089] When the electrical signals required by the external power supply and the load are the same, that is, when the values ​​of y and x are the same, in some possible implementations, such as Figure 7 As shown, the first input terminal 211 of the first connector 201 includes k sub-input terminals 2110 , and each sub-input terminal 2110 includes a first neutral line input terminal 2111 and a first phase line input terminal 2112 .

[0090] The first ends of the second phase line terminals 22111 in the k pairs of second power supply terminals 2211 are respectively electrically connected to the first phase line input terminals 2112 in the k sub-input terminals 2110, and the first ends of different second phase line terminals 22111 are electrically connected to different first phase line input terminals 2112 of the sub-input terminals 2110. The first ends of the second zero line terminals 22112 in the k pairs of second power supply terminals 2211 are respectively electrically connected to the first zero line input terminals 2111 in the k sub-input terminals 2110, and the first ends of different second zero line terminals 22112 are electrically connected to different first zero line input terminals 2111 of the sub-input terminals 2110.

[0091] The first connector 201 is used to receive h y-phase electrical signals through h sub-input terminals 2110 and convert the h y-phase electrical signals into h groups of x-phase electrical signals, and output the h groups of x-phase electrical signals to the power distribution module 10 through h pairs of second power terminals 2211 .

[0092] That is, when the values ​​of y and x are the same, the first connector 201 does not need to convert the electrical signal, and can directly output the electrical signal received as the electrical signal required by the load. In the embodiment of the present application, the first input terminal 211 of the first connector 201 may include k sub-input terminals 2110, and each of the k sub-input terminals 2110 includes a first zero line input terminal 2111 and a first phase line input terminal 2112. The k sub-input terminals 2110 are electrically connected to the k second power terminals 2211 in the first connection terminal 221 in a one-to-one correspondence. For each sub-input terminal 2110, the first phase line input terminal 2112 in the sub-input terminal 2110 is electrically connected to the first end of the second phase line terminal 22111 in the corresponding second power terminal 2211, and the first zero line input terminal 2111 in the sub-input terminal 2110 is electrically connected to the first end of the second zero line terminal 22112 in the corresponding second power terminal 2211. In this way, each sub-input terminal 2110 in the first connector 201 can receive the y-phase electrical signal separately, and then transmit the y-phase electrical signal to the second power terminal 2211. When the y-phase electrical signal is the same as the x-phase electrical signal, the first connector 201 can directly transmit the y-phase electrical signal received by the sub-input terminal 2110 to the second power terminal 2211 electrically connected to the sub-input terminal 2110, and the second power terminal 2211 is transmitted to the first power terminal 11 in the power distribution module 10. At this time, each sub-input terminal 2110 in the power distribution component is used for an external power supply. Since each sub-input terminal 2110 is used for an external power supply, the number of phase lines in the external power supply is the same as the number of first phase line input terminals 2112 in each sub-input terminal 2110 in the first input terminal 211 of the first connector 201, so that each sub-input terminal 2110 in the power distribution component can receive the electrical signal of the external power supply.

[0093] It should be understood that each sub-input terminal 2110 in the power distribution component is used for an external power supply, and the power supplies connected to the k sub-input terminals 2110 in the power distribution component can be different y-phase power supplies. That is, the power supplies connected to the k sub-input terminals 2110 in the power distribution component can be independent and unrelated to each other, so that the h groups of y-phase electrical signals output by the power distribution module 10 in the power distribution component are also independent and unrelated to each other.

[0094] For example, it is assumed that the external power supply in the power distribution component is a single-phase power supply, and the electrical signal required by the external load is a single-phase electrical signal. Figure 8aAs shown, the power distribution component includes a power distribution module 10 and a first connector 201. The power distribution module 10 includes three first power terminals 11, each of which includes a first phase terminal 111 and a first neutral terminal 112. The first connector 201 includes a first input terminal 211 and a first connection terminal 221. The first input terminal 211 includes three sub-input terminals 2110. Each sub-input terminal 2110 includes a first phase input terminal 2112 and a first neutral input terminal 2111. The first connection terminal 221 includes three second phase terminals 2211 and three second neutral terminals 2212. For each of the three second phase terminals 2211, the first end of the second phase terminal 2211 is electrically connected to the first phase input terminal 2112 of the corresponding sub-input terminal 2110, and the first ends of different second phase terminals 2211 are electrically connected to different sub-input terminals 2110. The second end of the second phase terminal 2211 is electrically connected to the first phase terminal 111 of the first power terminal 11 corresponding thereto, and the second ends of different second phase terminals 2211 are electrically connected to different first phase terminals 111. For each of the three second neutral terminals 2212, the first end of the second neutral terminal 2212 is electrically connected to the first neutral input terminal 2111 of the sub-input terminal 2110 corresponding thereto, and the first ends of different second neutral terminals 2211 are electrically connected to different sub-input terminals 2110. The second end of the second neutral terminal 2212 is electrically connected to the first neutral terminal 112 of the first power terminal 11 corresponding thereto, and the second ends of different second neutral terminals 2212 are electrically connected to different first neutral terminals 112, as shown in FIG. Figure 8b As shown. The number of phase lines in the external power supply is the same as the number of first phase line input terminals 2112 in each sub-input terminal 2110 in the first input terminal 211 of the first connector 201. In this way, when the three sub-input terminals 2110 of the power distribution component can all receive single-phase electrical signals, they can be directly transmitted to the three pairs of first power terminals 11 in the power distribution module 10 through the first connection terminal 221, and the three pairs of first power terminals 11 can output the received single-phase electrical signals. When the single-phase electrical signals received by the three sub-input terminals 2110 in the power distribution component are independent of each other, the single-phase electrical signals output by the three pairs of first power terminals 11 are also independent of each other.

[0095] As a possible implementation, Figure 9a As shown, in order to increase the safety of the power distribution component, when the first input terminal 211 includes k sub-input terminals 2110 , each sub-input terminal 2110 also includes a sub-grounding terminal 2113 , and the first connection terminal 221 includes a second grounding terminal 23 .

[0096] The k sub-ground terminals 2113 are electrically connected to the first end of the second ground terminal 23, and the second end of the second ground terminal 23 is electrically connected to the first ground terminal 12. Figure 9b shown.

[0097] It should be understood that the first connection terminal 221 in the first connector 201 is configured to be compatible with the power distribution module 10, and therefore the number of second phase line terminals 2211 included in the first connection terminal 221 in the first connector 201 is the same as the number of first phase line terminals 111 included in the power distribution module 10, the number of second neutral line terminals 2212 included in the first connection terminal 221 in the first connector 201 is the same as the number of first neutral line terminals 112 included in the power distribution module 10, and the number of second grounding terminals 23 included in the first connection terminal 221 in the first connector 201 is the same as the number of first grounding terminals 113 included in the power distribution module 10.

[0098] Based on this, when the power distribution module 10 includes a first ground terminal 113, the first connection terminal 221 includes a second ground terminal 23. At this time, the ground terminals included in the first input terminal 211 can be electrically connected to the second ground terminal at the first connection terminal 221. That is, in order to increase the safety of the sub-input terminal 2110, a sub-ground terminal 2113 is provided in each sub-input terminal 2110, and a second ground terminal 23 is provided in the first connection terminal 221. In this way, the sub-ground terminal 2113 in each sub-input terminal 2110 can be electrically connected to the first end of the second ground terminal 23, and the second end of the second ground terminal 23 can be electrically connected to the first ground terminal 221.

[0099] In some embodiments, when the first input terminal 211 includes a first neutral line input terminal 2111 and k first phase line input terminals 2112, in order to increase the safety of the power distribution component, the first input terminal 211 also includes a third grounding terminal 2114. At this time, the third grounding terminal 2114 is electrically connected to the first end of the second grounding terminal 23, and the second end of the second grounding terminal 23 is electrically connected to the first grounding terminal 12. Fig.10a and Fig.10b shown.

[0100] In this way, for different types of external power supplies, there is no need to replace the power distribution module 10 in the power distribution component. Only a first connector 201 with a different structure needs to be set to achieve compatibility with different types of power supplies, thereby improving the compatibility of the power distribution component and reducing the maintenance complexity of the cabinet using the power distribution component.

[0101] In order to reduce the cost of the power distribution components, an existing adapter can be used to adapt to the power distribution module 10 to realize the forwarding function of the power signal. At this time, when the external power supply and the electrical signal required by the load are different, that is, when the values ​​of y and x are different, in some embodiments, such as Fig.11 As shown, the conversion module 20 includes a second connector 202 and an adapter 203 .

[0102] The second connector 202 includes a second input terminal 212 and a second connection terminal 222, the second input terminal 212 includes a second neutral line input terminal 2121 and k second phase line input terminals 2122, the second connection terminal 222 includes a third neutral line terminal 2221 and k third phase line terminals 2222; the second neutral line input terminal 2121 is electrically connected to the first end of the third neutral line terminal 2221, and the first ends of the third neutral line terminals 2221 electrically connected to different second neutral line input terminals 2121 are different; the first ends of the k third phase line terminals 2222 are respectively electrically connected to the k second phase line input terminals 2122, and the first ends of different third phase line terminals 2222 are electrically connected to different second phase line input terminals 2122.

[0103] The adapter 203 includes a first adapter terminal 2031 and k second adapter terminals 2032 electrically connected to the first adapter terminal 2031, and the k second adapter terminals 2032 correspond one-to-one to the k third phase line terminals 2222; the second end of the third neutral line terminal 2221 is electrically connected to the first adapter terminal 2031, and the k second adapter terminals 2032 are respectively electrically connected to the first neutral line terminals 112 in the k pairs of first power terminals 11, and different second adapter terminals 2032 are electrically connected to different first neutral line terminals 112.

[0104] The second connector 202 is used to receive the y-phase electrical signal through the second input terminal 212 and convert the y-phase electrical signal into h groups of x-phase electrical signals, and output the h groups of x-phase electrical signals to the power distribution module 10 through h pairs of third power terminals. Each third power terminal includes a third phase line terminal 2222 in the second connector 202 and a corresponding second adapter terminal 2032 in the adapter 203.

[0105] That is, the conversion module 20 includes a second connector 202 and an adapter 203. Among them, the second connector 202 is an adapter of existing structure, that is, the second connector 202 can only transmit multiple electrical signals to the power distribution module 10, and cannot convert electrical signals. Based on this, the second connector 202 includes a second input terminal 212 and a second connection terminal 222. Among them, the second input terminal 212 includes a second neutral line input terminal 2121 and k second phase line input terminals 2122. The second connection terminal 222 includes a third neutral line terminal 2222 and k third phase line terminals 2221. The second input terminal 212 is used for an external power supply to receive a y-phase electrical signal. The first ends of the k third phase line terminals 2221 in the second connection terminal 222 are electrically connected to the k second phase line input terminals 2122, and the first end of each third phase line terminal 2221 is electrically connected to only one second phase line input terminal 2122, and the first ends of different third phase line terminals 2221 are electrically connected to different second phase line input terminals 2122. The first end of the third zero line terminal 2221 in the second connection terminal 222 is electrically connected to the second zero line input terminal 2121, so that the second input terminal 212 can transmit the received y-phase electrical signal to the second adapter terminal 2031. The adapter 203 is electrically connected to the second connector 202. The adapter 203 includes a first adapter terminal 2031 and k second adapter terminals 2032 electrically connected to the first adapter terminal 2031. In order to convert the y-phase electrical signal into h groups of x-phase electrical signals, it is necessary to divide the third zero-line terminal 2222 in the second connector 202 into a plurality of zero-line terminals, so that the number of zero-line terminals corresponds to the number of phase-line terminals, so that the received multi-phase electrical signal, i.e., the y-phase electrical signal, can be converted into h groups of x-phase electrical signals through the corresponding line terminals and zero-line terminals, and transmitted to the power distribution module 10. At this time, the third zero-line terminal 2222 can be divided by the adapter 203. That is, one end of the first adapter terminal 2031 of the adapter 203 is electrically connected to the second end of the third zero-line terminal 2221, and the other end of the first adapter terminal 2031 is electrically connected to k second adapter terminals 2032. The k second adapter terminals 2032 correspond to the k first power terminals 11 one by one, and each second connector 2032 is electrically connected to the first zero-line terminal 111 in the corresponding first power terminal 11. In this way, the third neutral line terminal 2222 can be divided into k pieces, which correspond to the third phase line terminals 2221 one by one. That is, the third neutral line terminal 2222 in the second connection terminal 222 can be divided into k second conversion terminals 2032 by the converter 203, and one second conversion terminal 2032 and one corresponding third phase line terminal 2221 form a third power supply terminal to transmit electrical signals.In this way, k third power terminals can be formed through the second connection end 222 and the converter 203. When the power distribution component receives the y-phase electrical signal through the second input end 212 of the second connector 202, the second input end 212 can be transmitted to the second connection end 222. Since the second connection end 222 and the converter 203 together form k third power terminals, when the y-phase electrical signal is transmitted to the second connection end 222, it is transmitted to the third power terminal. The y-phase signal can be directly converted into h groups of x-phase electrical signals through the third power terminal and transmitted to the power distribution module 10 through the h third power terminals.

[0106] In some possible implementations, the number k of the second phase line input terminals 2122 in the second adapter 202 is the same as the number of phases of the external power supply, so that the second connector 202 can be electrically connected to the external power supply to receive electrical signals.

[0107] In some possible implementations, the values ​​of y and k are both 3, that is, the external power supply is a three-phase power supply.

[0108] As a possible implementation manner, the value of x is 1, that is, the electrical signal output by the power distribution component to the load is a single-phase electrical signal.

[0109] For example, it is assumed that the external power supply in the power distribution component is a three-phase power supply, and the electrical signal required by the external load is a single-phase electrical signal. Fig.12a and Figure 12bAs shown, the power distribution assembly includes a power distribution module 10, a second connector 202 and a converter 203. The second connector 202 includes a second input terminal 212 and a second connection terminal 222. The second input terminal 212 includes three second phase line input terminals 2122 and a neutral line input terminal 2123. The second connection terminal 222 includes three third phase line terminals 2221 and a third neutral line terminal 2222. The converter 203 includes a first conversion terminal 2031 and three second conversion terminals 2032. One end of the three second conversion terminals 2032 is electrically connected to one end of the first conversion terminal 2031. The other end of the first conversion terminal 2031 is electrically connected to the second end of the third neutral line terminal 2222. The other ends of the three second conversion terminals 2032 correspond one-to-one to the three first power terminals 11 in the power distribution module 10. The other end of each second conversion terminal 2032 is electrically connected to the first neutral line terminal of the corresponding first power terminal 11. The three second phase line input terminals 2122 correspond one-to-one to the three third phase line terminals 2221 of the second connection terminal 222, and each second phase line input terminal 2122 is electrically connected to the first end of the corresponding third phase line terminal 2221. The first zero line input terminal 2121 is electrically connected to the first end of the third zero line terminal 2222. The second ends of the three third phase line terminals 2221 of the second connection terminal 222 correspond one-to-one to the three first power terminals 11 in the power distribution module 10. The second end of each third phase line terminal 2221 is electrically connected to the first phase line terminal 111 of the corresponding first power terminal 11.

[0110] In this way, when the second connector 202 is connected to an external 3-phase power supply, the three phase lines of the external 3-phase power supply usually share a neutral line. Therefore, the three second phase line input terminals 2122 of the second connector 202 are electrically connected to the three phase lines of the external 3-phase power supply, and the second neutral line input terminal 2121 is electrically connected to the neutral line of the external 3-phase power supply. After the second input terminal 212 of the second connector 202 receives the three-phase electrical signal, when the three-phase electrical signal is transmitted to the second connection terminal 222, since the second connection terminal 222 is electrically connected to the converter 203, the third neutral line terminal 2222 can be divided into three second conversion terminals 2032 through the converter 203, and a second conversion terminal 2032 and a third phase line terminal 2221 form a pair of third power terminals to transmit a single electrical signal. In this way, three pairs of third power terminals can be formed in the power distribution component through the converter 203, and the three-phase electrical signal can be directly divided into three single-phase electrical signals through the three pairs of third power terminals, and the three single-phase electrical signals are respectively transmitted to the three pairs of first power terminals 11 in the power distribution module 10, so as to be transmitted to the external load through the first power terminals 11.

[0111] Alternatively, when the electrical signal required by the external power supply and the load is the same, that is, when the values ​​of y and x are the same, in some embodiments, Fig.13As shown, the conversion module 20 includes a third connectors 204. Wherein, a is an integer greater than 0 and not greater than k.

[0112] Each third connector 204 includes a third input terminal 213 and a fourth connection terminal 223. In each third connector 204, the third input terminal 213 includes a third neutral line input terminal 2131 and a third phase line input terminal 2132, and the fourth connection terminal 223 includes a fourth neutral line terminal 2232 and a fourth phase line terminal 2231. A first end of the fourth neutral line terminal 2232 is electrically connected to the third neutral line input terminal 2131, and a first end of the fourth phase line terminal 2231 is electrically connected to the third phase line input terminal 2132.

[0113] The second ends of the fourth phase terminals 2231 of a third connector 204 are respectively electrically connected to the first phase terminals 111 of a pair of first power terminals 11, and the second ends of different fourth phase terminals 2231 are electrically connected to different first phase terminals 111. The second ends of the fourth zero terminals 2232 of a third connector 204 are respectively electrically connected to the first zero terminals 112 of a pair of first power terminals 11, and the second ends of different fourth zero terminals 2232 are electrically connected to different first zero terminals 112.

[0114] The third connector 204 is used to receive the y-phase electrical signal through the third input terminal 213 and convert the y-phase electrical signal into a group of x-phase electrical signals, and output the group of x-phase electrical signals to the power distribution module 10 through the fourth connection terminal 223 .

[0115] That is, when the values ​​of y and x are the same, the third converter 204 does not need to convert the electrical signal, and can directly output the electrical signal it receives as the electrical signal required by the load. In the embodiment of the present application, the structure of the third connector 204 is an existing connector structure. That is, the third connector 204 includes a third input terminal 213 and a fourth connection terminal 223. The third input terminal 213 includes a third zero line input terminal 2131 and a third phase line input terminal 2132, and the fourth connection terminal 223 includes a fourth zero line terminal 2232 and a fourth phase line terminal 2231. The first end of the fourth zero line terminal 2232 is electrically connected to the third zero line input terminal 2131, and the first end of the fourth phase line terminal 2231 is electrically connected to the third phase line input terminal 2132. In order to match the number of first power terminals 11 in the power distribution module 10 in the power distribution component, a third connector 204 is provided in the power distribution component. At this time, a third connector 204 corresponds one-to-one to the first power terminal 11 in the power distribution module 10. And the second end of the fourth phase line terminal 2231 in each third connector 204 is electrically connected to the first phase line terminal 111 in the corresponding first power terminal 11, and the second ends of the fourth phase line terminals 2231 in different third connectors 204 are electrically connected to different first power terminals 11. The second end of the fourth zero line terminal 2232 in each third connector 204 is electrically connected to the first zero line terminal 112 in the corresponding first power terminal 11, and the second ends of the fourth zero line terminals 2232 in different third connectors 204 are electrically connected to different first power terminals 11. In this way, when there is a third connector 204 that receives a y-phase electrical signal, the third connector 204 can transmit the received y-phase electrical signal to the corresponding first power terminal 11, which is output by the first power terminal 11.

[0116] It should be understood that the number a of the third connectors 204 can be set by the user according to actual needs. Since the power distribution module 10 only includes k first power terminals 11, the value of a cannot be greater than k.

[0117] In some embodiments, the value of n is 3, and / or the value of m is 1. That is, the power distribution module 10 in the power distribution assembly can transmit a 3-phase electrical signal, in which case the value of n can be 3. And / or the power distribution module 10 in the power distribution assembly can also transmit a single-phase electrical signal, in which case the value of m is 1.
