Description

Technical Field

[0001] The present invention relates to the technical field of power distribution units, and in particular to a power distribution unit with replaceable modules. Background Art

[0002] With the rapid development of computer technology and the Internet, the services provided by the Internet are also increasing, especially emerging technologies such as cloud computing and cloud storage, which are inseparable from people's lives. Therefore, the number of data center rooms composed of multiple computers, servers or workstations is also increasing day by day. In order to provide more and faster services and functions, the number of computers, servers or workstations must be increased, and problems such as power supply and distribution in data center rooms will also arise. In order to solve the problems of power supply and distribution in data center rooms, the industry uses power distribution units (PDUs) to distribute the power required by each load device such as a computer, server or workstation.

[0003] As an important guarantee for the safe use of electricity in data center rooms, the stability and safety of the power distribution unit are directly related to the safety of the load equipment and even the entire room. With the rapid development and application of the Internet of Things, artificial intelligence, and 5G communications, new load equipment needs to be connected to the power distribution unit in the data center rooms of enterprises in the communications, power, radio and television industries. This requires that the sockets of the power distribution unit can be replaced and increased or decreased.

[0004] In the related art known to the inventor, some power distribution units have the function of replaceable sockets. In the power distribution unit, the distribution unit body is provided with a conductive busbar group, which includes a plurality of conductive busbars, which are spaced to form three slots, and a plurality of sockets can be detachably plugged into and unplugged from the slots of the conductive busbar group. When replacing a socket, the computer room manager first pulls out the three pins of the socket to be replaced from the three slots of the conductive busbar group, and then aligns the three protruding pins of the new socket with the three slots of the conductive busbar group one by one and inserts them horizontally to avoid tilting, squeezing and deformation of the three pins of the socket and the three slots of the conductive busbar group. Therefore, in the process of replacing the socket, the computer room manager is prone to deformation of the slot due to improper operation when plugging and unplugging the socket pins, thereby affecting the normal operation of other load equipment and the safety and reliability of the computer room.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0044] Please refer to Figure 1 and Figure 2 The present invention provides a technical solution for a power distribution unit with replaceable modules. The power distribution unit includes a distribution unit body 100, a module 200 and a wire assembly 300. The distribution unit body 100 is provided with an external power input terminal 110 and a power output terminal 120. The external power input terminal 110 is used to connect to an external power source. The external power source can be a local mains power supply network or a battery. The power output terminal 120 is electrically connected to the external power input terminal 110. It can be understood that the connection between the power output terminal 120 and the external power input terminal 110 can be a direct connection or an indirect connection. For example, circuit elements such as a voltage regulator are also connected between the external power input terminal 110 and the power output terminal 120.

[0045] The module 200 is detachably mounted on the distribution unit body 100. The module 200 includes a power input terminal 210 and an output socket 220 which are electrically connected to each other. The power input terminal 210 is detachably electrically connected to the power output terminal 120. The output socket 220 is used to be electrically connected to a load device.

[0046] One end of the wire assembly 300 is connected to the power output end 120 , and the other end is detachably connected to the power input end 210 .

[0047] In the power distribution unit of the replaceable module, the distribution unit body 100 obtains external electric energy through the external power input terminal 110, and supplies the electric energy to the load device through the power output terminal 120, the power input terminal 210, the wire assembly 300 and the output socket 220, so as to realize the supply and distribution of electric power. When the module 200 needs to be replaced, the user removes the wire assembly 300 from the power input terminal 210, removes the module 200 from the distribution unit body 100, and then connects the wire assembly 300 to the power input terminal 210 of the new module 200, and fixes the module 200 on the distribution unit body 100, so as to realize the replacement of the module 200. The power output terminal 120 is indirectly connected to the power input terminal 210 through the flexible wire assembly 300, which ensures that the removal and installation of the module 200 is safer, more reliable, more flexible, simpler and more efficient than the rigid direct connection, especially in a small and nearly closed machine room (cabinet is a kind of machine room).

[0048] In addition, the wire assembly 300 can be formed by combining existing mature electrical cables and plugs, which is technically safer and more reliable.

[0049] Specifically, combined Figure 1 and Figure 2 , there are more than two power output terminals 120, which are arranged in parallel, and each power input terminal 210 is independent of each other and does not affect each other, and supports live operation. In addition, the distribution unit body 100 is equipped with a power output terminal 120 for each power input terminal 210 of each module 200, rather than multiple modules 200 sharing one power output terminal 120, so that when the user replaces a certain module 200, it will not cause poor contact of other modules 200, and will not affect the normal operation of other modules 200, which further ensures the safety and reliability of the power distribution unit during the process of replacing the module 200.

[0050] Furthermore, there are more than two modules 200. It should be noted that although there are more than two power output terminals 120 and modules 200, the number of power output terminals 120 and modules 200 does not necessarily correspond one to one, and the two may be equal in number or unequal in number. For example, Figure 1 and Figure 2 In the power distribution unit with replaceable modules shown in , the number of power output terminals 120 and modules 200 are equal. Of course, in other embodiments, the number of power output terminals 120 can be greater than the number of modules 200, that is, some power output terminals 120 are idle. The temporarily idle power output terminals 120 can be used to install additional modules 200 when the power distribution unit is expanded in the future; can be used to install temporary modules 200 to facilitate the access of temporary test equipment, etc.; can also be used as a fault backup for other power output terminals 120 in use.

[0051] In this embodiment, the distribution unit body 100 is in a long strip shape.

[0052] In this embodiment, there are many ways to detachably install the module 200 to the distribution unit body 100. For example, the module 200 can be detachably snap-fitted, detachably sleeved, threaded, bonded, magnetically adsorbed, etc.

[0053] In one embodiment, in combination Figure 2 The distribution unit body 100 is further provided with a base 130, and two or more power output terminals 120 are arranged at intervals on the top surface of the base 130 to separate the base 130 into a plurality of installation slots 140. That is, two adjacent power output terminals 120 and the top surface of the base 130 located between the two adjacent power output terminals 120 together form the installation slot 140, and the top of the installation slot 140 is open. The module 200 is installed in the installation slot 140.

[0054] In this way, the user can install the module 200 from top to bottom into the open installation groove 140 at the top. Compared with side installation or bottom installation, the user installs from top to bottom, which has a better line of sight and is easy to accurately align and install, making the operation of replacing the module 200 safer, faster and more efficient.

[0055] Furthermore, the module 200 is installed in the installation groove 140, and the power input terminal 210 of the module 200 is electrically connected to the adjacent power output terminal 120, which facilitates the layout and makes the power distribution unit structure of the above-mentioned replaceable module more compact.

[0056] Furthermore, the wiring of the power output terminal 120 and the external power input terminal 110 is inside the base 130, which meets better industry technical standards, and the wiring is safer, ensuring that the power distribution unit of the replaceable module proposed in the present invention is safer and more reliable.

[0057] In one embodiment, reference Figure 2 The power output terminal 120 is adjustably arranged on the base 130 to adjust the length of the mounting slot 140. In this way, the length of the mounting slot 140 is adjustable, and the modules 200 of different lengths can be intelligently matched, and the output format, output bit number, and specification model of the module 200 are not restricted, so that the replacement of the module 200 is convenient and the versatility is strong.

[0058] Specifically, there are many ways to adjust the position of the power output terminal 120. For example, the power output terminal 120 is slidably set on the base 130 by means of a slider and a guide rail to achieve adjustable position. For another example, the base 130 is provided with a row of positioning holes, and the power output terminal 120 can be selectively installed in different positioning holes to adjust its installation position.

[0059] In another embodiment, reference may be made to Figure 2 and Figure 3 The module 200 includes a plurality of output sockets 220, which are detachably connected in series to adjust the length of the module 200. In this way, the length of the module 200 is adjustable, and the number, specification, and output format of the output sockets 220 can be intelligently adjusted, and can be arbitrarily combined into a replaceable module 200.

[0060] Specifically, a module 200 includes a power input terminal 210 and three output sockets 220. The power input terminal 210, the first output socket 220, the second output socket 220 and the third output socket 220 are connected together in sequence. When the length of the module 200 needs to be adjusted, the third output socket 220 can be removed to reduce the length of the module 200, or a fourth output socket 220 can be added and installed on the side of the third output socket 220 away from the second output socket 220, thereby increasing the length of the module 200.

[0061] In the above embodiment, the length of the mounting groove 140 and / or the length of the module 200 is adjustable, so that the power distribution unit of the above replaceable module is more intelligent, can meet the different size requirements of users, has strong versatility, and can adapt to the replacement or increase or decrease of the module 200 in the future.

[0062] In this embodiment, see Figure 1 and Figure 2 The number of the wire assemblies 300 corresponds one to one with the number of the power output terminals 120 .

[0063] In one embodiment, the power distribution unit of the replaceable module further includes at least one of the following:

[0064] The wire assembly 300 is connected to the top of the power output terminal 120; and

[0065] The wire assembly 300 is connected to the top of the power input terminal 210 .

[0066] The connection position of the above-mentioned wire assembly 300 is located at the top of the power output terminal 120 and / or the top of the power input terminal 210. When the user replaces the module 200, the line of sight is better and it is easy to align and connect, making the operation of replacing the module 200 safer, faster and more efficient.

[0067] In one embodiment, in combination Figure 4 and Figure 5The wire assembly 300 is plugged into the power output terminal 120, and a first threaded member 310 is provided at the end of the wire assembly 300 close to the power output terminal 120, and the power output terminal 120 is provided with a second threaded member 121 that matches the first threaded member 310. The threaded connection method can ensure that the connection between the wire assembly 300 and the power output terminal 120 is more secure under the premise of being detachable.

[0068] In one embodiment, in combination Figure 4 and Figure 5 The power input terminal 210 is provided with a mounting hole 211 of unequal length and width, a pin 230 is provided in the mounting hole 211, and a protrusion 320 is provided at the end of the wire assembly 300 close to the power input terminal 210, the outer contour of the protrusion 320 is adapted to the mounting hole 211, and the protrusion 320 is provided with a socket corresponding to the pin 230. In this way, the length and width of the mounting hole 211 are unequal, so that the protrusion 320 will not be installed upside down, which facilitates accurate alignment when the wire assembly 300 is connected to the power input terminal 210, and realizes safety, efficiency and convenience in the replacement process of the module 200.

[0069] In one embodiment, the power distribution unit of the replaceable module further includes at least one of the following:

[0070] The power output terminal 120 is provided with a first switch (not shown);

[0071] The power input terminal 210 is provided with a second switch (not shown);

[0072] The power output terminal 120 is provided with a first leakage protector (not shown);

[0073] The power input terminal 210 is provided with a second leakage protector (not shown).

[0074] In this way, when replacing the module 200, the user can turn off the first switch and / or the second switch to avoid the risk of electric shock; when electric shock occurs, the first leakage protector can cut off the current of the corresponding power output terminal 120, and / or the second leakage protector can cut off the current of the corresponding module 200 to protect the user, but it does not affect the normal operation of other modules 200. Therefore, the power distribution unit of the replaceable module can ensure safety and reliability during the process of replacing the module 200.

[0075] In one embodiment, in combination Figure 4 and Figure 5 A first wire cavity 150 is provided inside the distribution unit body 100 , and the external power input terminal 110 and the power output terminal 120 are connected by a first wire (not shown), and the first wire is arranged in the first wire cavity 150 .

[0076] In another embodiment, the module 200 is provided with a second wire cavity 260 , and the power input terminal 210 and the output socket 220 are connected via a second wire (not shown), and the second wire is arranged in the second wire cavity 260 .

[0077] In the above two embodiments, the distribution unit body 100 and / or the module 200 adopts an internal wiring method with a high degree of modularization, avoiding exposed wires, and meeting the higher technical standards of the industry. The power distribution unit with the above replaceable module can ensure safety and reliability during the process of replacing the module 200 and in daily use.

[0078] In one embodiment, in combination Figure 3 At least one module 200 has more than two output sockets 220, and the more than two output sockets 220 are arranged in parallel. In this way, at least one module 200 can supply power to multiple load devices, and the more than two output sockets 220 are independent of each other and do not interfere with each other.

[0079] Specifically, the output standards of the multiple output sockets 220 are independent of each other. The output standards include GB1002_10A, GB1002_16A, IEC320_C13, IEC320_C19, etc. The output sockets 220 with independent output standards can meet the different output standard usage requirements of the customer site. On the same power distribution unit, the actual required socket standard can be flexibly replaced according to different needs. That is, a module 200 can provide different output standards, and a power distribution unit can provide a variety of output standards.

[0080] Specifically, the module 200 is provided with signal indicator lights 240 corresponding to the plurality of output sockets 220. The user can learn the use status of the output sockets 220 according to the signal indicator lights 240, find faults in time, and replace the module 200 in time.

[0081] Specifically, the module 200 is provided with control elements (not shown) corresponding to the plurality of output sockets 220. The user can intelligently control the opening and closing of the output sockets 220 and the corresponding load devices according to the operating status of the output sockets 220.

[0082] Specifically, the module 200 is provided with mounting positions 250 corresponding to a plurality of output sockets 220, and the output sockets 220 are detachably mounted in the mounting positions 250, that is, the output sockets 220 are replaceable. In this way, a module 200 can have output sockets 220 of different specifications and models, without limiting the output format of the output sockets 220 or the number of output bits of the output sockets 220, and can be arbitrarily combined into a replaceable module 200 as required.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
