[0001] The present application relates to the technical field of power supply equipment, and in particular to an uninterruptible power supply equipment. Background Art

[0002] The current uninterruptible power supply (UPS) equipment has a complex connection method between the input and output sockets, signal terminals and power boards. There are two main power distribution connection methods:

[0003] Method 1: The power board and input socket of the uninterruptible power supply device are connected by cables, each output socket has a separate lead, and jumpers are used to connect the output sockets.

[0004] Method 2: The power board of the uninterruptible power supply device is connected to the input socket through a cable, the output sockets are cascaded through a printed circuit board (PCB), and the PCB is connected to the socket through a cable.

[0005] It can be seen that the traditional power distribution connection method has problems such as too many distribution cables inside the uninterruptible power supply equipment, too long cable links and chaotic cable layout, which makes the manufacturing process complicated and the yield is low.

[0006] Furthermore, the current trend towards miniaturization of uninterruptible power supplies places higher demands on design space and requires the addition of multiple anti-interference magnetic rings inside the product, making the power distribution connection design of the uninterruptible power supply more difficult.

[0007] Therefore, how to reduce the number of cables inside the uninterruptible power supply equipment and simplify the power distribution connection design of the uninterruptible power supply is an urgent problem to be solved. Utility Model Content

The pins of each input socket are welded on the power board and on one side close to the first panel, and the input end of each multi-position output socket is connected to the neutral output end and the live output end of the power board.

[0010] Based on the technical solution of this design, the input socket can be directly welded onto the board to avoid the use of cables to connect to the power board, greatly shortening the connection link and eliminating the need to add magnetic rings to resist interference.

[0016] Since some multi-output sockets not only require one live and one zero, but also require copper bar output, the copper bar in this design also includes a first copper bar output component and a second copper bar output component to meet the user's copper bar needs. In addition, the copper bar output component and the input conductive sheet are connected by the fourth metal component and the fifth metal component, so that the second copper bar output component and the live wire input conductive sheet are arranged relative to each other, thereby shortening the design length of the socket and improving the utilization rate of uninterrupted energy space.

[0022] Based on the technical solution of the present design, when the live wire input and the neutral wire input are not needed, the sliding cover slides to the first end of the guide portion to cover the live wire input conductive sheet and the neutral wire input conductive sheet, thereby preventing dust or other foreign matter from falling in, reducing the clearance distance with other equipment, and allowing the output socket to be closely arranged with other electrical equipment. In addition, the design of the limiting portion can prevent the sliding cover from sliding out and falling off.

[0023] When live wire input and neutral wire input are needed, the sliding cover slides to the second end of the guide portion to expose the live wire input conductive sheet and the neutral wire input conductive sheet, and then the wiring is performed.

[0043] For ease of description and understanding, the technical terms used in this application are first introduced:

[0044] 1. Uninterruptible Power Supply

[0045] Uninterruptible power supply is a power supply with energy storage device. It is mainly used to provide uninterruptible power input to some equipment with high requirements on power stability. UPS small machine generally refers to uninterruptible power supply equipment with power below 10k.

[0046] 2. Standard aircraft and long aircraft

[0047] The standard machine refers to a motor-ready uninterruptible power supply, which usually has its own battery; the long-term machine refers to a long-term backup uninterruptible power supply, which usually has an external battery.

[0048] 3. Copper Busbar

[0049] Copper busbar, also known as copper busbar or copper busbar, is made of beryllium copper, silver copper and other materials. It is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section. It is used to transmit current in circuits and connect electrical equipment.

[0050] In order to make the purpose, technical solutions and advantages of the present application clearer, the following is a clear and complete description of the application scenarios of the technical solutions in the embodiments of the present application and the technical problems to be solved:

[0051] With the development of science and technology and data, the demand for data centers is increasing. For critical power supply systems related to major economic interests or public order, such as computing centers, emergency command centers, railway signal systems and control centers, civil aviation control centers and airport command centers, financial clearing centers and trading centers, etc., uninterruptible power supplies must be used for power supply.

[0052] Traditional UPSs have many distribution cables, too long cable links, and messy cable layouts, which makes the power distribution design of UPS equipment too complicated and has a low yield rate.

[0053] For example, there are two main power distribution connection methods for uninterruptible power supply equipment:

[0054] Method 1: The power board and input socket of the uninterruptible power supply device are connected by cables, each output socket is independently connected to the power board, and jumpers are used to connect the output sockets.

[0055] For example, the output socket of UPS involves multiple ports. The ports of the same line are connected in parallel through cables. The cables and the pins at the rear end of the socket are welded together through welding process. If there are two output lines, two cables need to be connected separately.

[0056] The disadvantage of this connection method is that there are many cables inside the UPS, and the parallel link is long, which will cause interference inside the power supply equipment, and it is necessary to add a magnetic ring to achieve anti-interference;

[0057] Furthermore, multiple sockets require multiple sets of cables or jumpers to connect, which is a complex process with uncontrollable quality. The power supply product involves multiple sets of flying wires, with a chaotic internal layout, and the cables need to be welded during the assembly of the whole machine, which has poor manufacturability and difficult to control welding quality.

[0058] Method 2: The power board of the uninterruptible power supply device is connected to the input socket through a cable, the output sockets are cascaded through a printed circuit board (PCB), and the PCB is connected to the socket through a cable.

[0059] The disadvantage of this connection method is that the PCB occupies a large space, which places too high requirements on the internal design and internal space of the UPS, and is not conducive to miniaturization design;

[0060] Furthermore, the power board and PCB are directly connected through cables, and the cables need to be soldered to the PCB. The soldering quality is uncontrollable and the long-term reliability is poor.

[0061] Based on the above problems, an embodiment of the present application provides an uninterruptible power supply device to solve the problem of too many cables inside the uninterruptible power supply device and complex power distribution connection of the uninterruptible power supply device.

[0062] The uninterruptible power supply equipment provided by this application is Figure 1a or Figure 2a As shown, the uninterruptible power supply device includes a device housing 101, at least one input socket (in the drawings of the present application, input socket 1021 and input socket 1022 are shown), at least one multi-position output socket ( Figure 1a The multiple output sockets 1031 and 1032 are shown in FIG. Figure 2a1033 is shown in the figure), battery 104 and power board 105, the device housing 101 includes multiple panels (the device housing 101 in the drawings of the present application includes a first panel 1011, a second panel 1012, a top shell 1013, a bottom plate 1014, a first side plate 1015 and a second side plate 1016), and the first panel 1011 is any panel among the multiple panels;

[0063] It should be noted that the input socket in the embodiment of the present application can be an AC input socket for connecting to an AC source such as mains electricity, such as a C20 socket, or it can be a DC input socket for connecting to a DC source such as an external battery in a long machine.

[0064] like Figure 1a or Figure 2a As shown, the device housing 101 encloses a first accommodation space A and a second accommodation space B arranged along a first direction, wherein the first direction is the length direction of the first panel 1011, each input socket and the power board 105 are located in the first accommodation space A, and each multi-position output socket and the battery 104 are located in the second accommodation space B;

[0065] like Figure 1b or Figure 2b As shown, the first panel 1011 includes a window ( Figure 1b It is shown in windows C1 to C4. Figure 2b The housings of at least one input socket and at least one multi-position output socket are respectively embedded in the corresponding windows;

[0066] Please refer to the soldering position of the input socket Figure 3 The pins of each input socket are welded on the power board 105 and close to the side of the first panel 1011, and the input end of each multi-position output socket is connected to the neutral line output end and the live line output end of the power board 105. It can be understood that since the welding position is close to the first panel 1011, it is convenient to weld the input socket onto the board during assembly.

[0067] It should be noted that Figure 3 for Figure 1a The power board 105 of the uninterruptible power supply shown in FIG. Figure 1a The uninterruptible power supply shown includes a plurality of output sockets 1031 and a plurality of output sockets 1032. Figure 3 It includes a neutral line output terminal N', a live line output terminal L1' and a live line output terminal L2'. The neutral line output terminal N' is used to connect to the neutral line input of the multi-position output socket 1031 and the multi-position output socket 1032. The live line output terminal L1' is used to connect to the live line input of the multi-position output socket 1031. The live line output terminal L2' is used to connect to the live line input of the multi-position output socket 1032.

[0068] Based on the technical solution of this embodiment, the input socket can be directly welded onto the board to avoid the use of cables to connect to the power board, which greatly shortens the connection link and does not require the addition of a magnetic ring to resist interference.

[0069] The above uninterruptible power supply is described below in conjunction with embodiments and drawings:

[0070] In a possible embodiment, Figure 4 As shown, each multi-position output socket includes a copper bar 401 and at least two three-hole insulating members (see Appendix 1 of this application). Figure 4 In the figure, three-hole insulating parts 4021 to 4023 are shown;

[0071] In addition, if Figure 4 As shown, each multi-position output socket further includes a housing 403, and each copper bar 401 is partially engaged in the insertion holes of at least two three-hole insulating members, and at least two insulating members are detachably connected to the housing 403 of the output socket.

[0072] like Figure 5a As shown, each copper busbar includes at least two groups of conductive sheets ( Figure 5a ), a first metal component 502 , a second metal component 503 and a third metal component 504 .

[0073] Each group of conductive sheets includes a neutral conductive sheet ( Figure 5a In the figure, the neutral line conductive sheet 1A-neutral line conductive sheet 3A are shown), the live line conductive sheet ( Figure 5a The live wire conductive sheet 1B-live wire conductive sheet 3B are shown) and the ground wire conductive sheet ( Figure 5a In the figure, the ground wire conductive sheet 1C-ground wire conductive sheet 3C are shown), and each set of conductive sheets is clamped in the neutral wire jack, the live wire jack and the ground wire jack of the corresponding three-hole insulating member;

[0074] It should be noted that the conductive sheet of the copper busbar 401 is clamped in the three-hole insulating member, which can fix the conductive sheet, making it convenient for users to plug and unplug the plug, avoiding the loosening and displacement of the conductive sheet during the plug and unplug process, and the poor contact between the conductive sheet and the plug.

[0075] The first metal member 502 is connected to each neutral line conductive sheet in sequence, the second metal member 503 is connected to each live line conductive sheet in sequence, and the third metal member 504 is connected to each ground line conductive sheet in sequence.

[0076] Based on the technical solution in this embodiment, each group of conductive sheets is clamped in the corresponding three-hole insulating member to form a socket, and the metal member connects the conductive sheets, thereby realizing cascading between the sockets of the multi-position output sockets, avoiding the use of cables or PCB boards to realize socket cascading, and simplifying the power distribution design of the uninterruptible power supply. In addition, after the copper busbar is designed according to the requirements of the uninterruptible power supply equipment, it can be directly produced and formed. Compared with cable welding and other methods, the copper busbar is more convenient to install and has a higher product yield.

[0077] In a possible embodiment, Figure 5a As shown, the first metal member 502 includes a live line input conductive sheet L, and the second metal member 503 includes a neutral line input conductive sheet N;

[0078] The neutral line input conductive sheet N is located at one end of the first metal member 502 close to the power board 105 and is used to connect to the neutral line output end of the power board 105;

[0079] The live wire input conductive sheet L is located at one end of the second metal member 503 close to the power board 105 , and is used for connecting to the live wire output end of the power board 105 .

[0080] It can be understood that for some multi-output sockets that do not require copper busbar outputs, such as sockets that comply with the International Electrotechnical Commission (IEC) standard, the end of the first metal part 502 close to the power board can be made into a neutral line input conductive sheet N, and the end of the second metal part 503 close to the power board can be made into a live line input conductive sheet L, which facilitates the integrated design of the copper busbar and does not require additional welding with additional metal sheets. It also meets the needs of one live and one neutral DC input, thereby realizing the miniaturization requirements of the uninterruptible power supply.

[0081] In a possible embodiment, Figure 5b As shown, the copper bar further includes a first copper bar output component T1, a second copper bar output component T2, a live line input conductive sheet L, a neutral line input conductive sheet N, a fourth metal component 505 and a fifth metal component 506;

[0082] One end of the neutral line input conductive sheet N is connected to one end of the first metal member 502 close to the power board 105, and the other end of the neutral line input conductive sheet N is connected to the first copper busbar output member T1 through the fourth metal member 505, wherein the first copper busbar output member T1 is arranged opposite to the neutral line input conductive sheet N;

[0083] One end of the live wire input conductive sheet L is connected to one end of the second metal component 503 close to the power board 105, and the other end of the live wire input conductive sheet L is connected to the second copper busbar output component T2 through the fifth metal component 506, wherein the second copper busbar output component T2 is arranged opposite to the live wire input conductive sheet L.

[0084] It is understandable that for some multi-position output sockets that need to be equipped with copper busbar output, copper busbar output parts are also required for technicians to connect and realize copper busbar output. This technical solution connects the copper busbar output parts and the input conductive sheet through metal parts. The copper busbar output parts and the input conductive sheet are arranged relatively, which can not only meet the needs of one-hot and one-zero DC input and copper busbar output, but also shorten the length of the socket and realize the miniaturization requirements of the uninterruptible power supply.

[0085] In a possible embodiment, Figure 5b As shown, the third metal member 504 includes a protective conductive sheet PE;

[0086] The protective conductive sheet PE is located at one end of the third metal member 504 away from the power board 105. Figure 6 As shown, the protective conductive sheet ( Figure 6 The protective conductive sheet PE1 and the protective conductive sheet PE2 are shown in FIG. 1 ) and are partially exposed on the multi-position output socket ( Figure 6 In addition to the multi-position output socket 1031 and the multi-position output socket 1032 shown in the figure, it is used to connect to the equipment casing for casing grounding protection.

[0087] It can be understood that the protective conductive sheet is partially exposed outside the housing of the output socket and connected to the device housing through bolts, so that the housing grounding protection can be achieved without using cables.

[0088] In a possible embodiment, Figure 5a As shown, each multi-position output socket also includes a protective conductive sheet PE;

[0089] The protective conductive sheet PE is connected to an end of the third metal member 504 away from the power board 105 , wherein the protective conductive sheet PE is partially exposed outside the multi-position output socket for connection with the device casing to provide casing grounding protection.

[0090] For example, Figure 5a As shown, the multi-position output socket includes a cascaded C13 socket 5014 and a C19 socket 5015. The C19 socket 5015 includes a neutral conductive sheet 4A, a live conductive sheet 4B and a ground conductive sheet 4C. The protective conductive sheet PE is fixedly connected to the ground conductive sheet 4C of the C19 socket. Since the cascaded C13 socket and the C19 socket are far apart, it is not easy to uniformly design and manufacture the copper busbar. The ground conductive sheet 4C is connected to one end of the third metal member 504 through a welding wire l3, the neutral conductive sheet 4A is connected to one end of the first metal member 502 through a welding wire l1, and the live conductive sheet 4B is connected to one end of the second metal member 503 through a welding wire l2, thereby realizing the cascading of the C13 socket 5014 and the C19 socket 5015.

[0091] It should be noted that if Figure 6 As shown, the protective conductive sheet ( Figure 6 The protective conductive sheet PE1 and the protective conductive sheet PE2 are shown in FIG. 1 ) and are partially exposed on the multi-position output socket ( Figure 6 The outer shell of the multi-position output socket 1031 and the multi-position output socket 1032 is shown in the figure, which is used to connect to the equipment casing for casing grounding protection.

[0092] Understandable, such as Figure 6 As shown, the protective conductive sheet is partially exposed outside the housing of the output socket and connected to the device housing through bolts, so that the housing grounding protection can be achieved without using cables.

[0093] In a possible embodiment, Figure 4 As shown, each socket of the multi-position output socket also includes a safety door ( Figure 4 The safety door is composed of a spring and a baffle. When no plug is inserted, the baffle blocks the conductive sheet under the action of the spring to meet the protection level and prevent electric shock to the human body. When the plug is inserted, the plug presses down the baffle, and the baffle further supports the plug under the action of the spring to prevent the plug from deflecting.

[0094] In a possible embodiment, Figure 4 As shown, the housing of each multi-position output socket includes a sliding cover 405, a socket front plate 406, a socket side shell 407 and a socket rear plate 408;

[0095] The socket side shell 407 includes a first opening K1 and a second opening K2 opposite to each other, the socket front plate 406 is covered on the first opening K1, the sliding cover 405 and the socket rear plate 408 are covered on the second opening K2, and the sliding cover 405 and the socket rear plate 408 are sequentially arranged along the length direction of the first panel 1011;

[0096] The socket front panel 406 is provided with a plurality of sockets;

[0097] like Figure 4 as well as Figure 7a As shown, one end of the socket rear plate 408 close to the slide cover 405 is provided with a guide portion 701 extending along the length direction of the first panel 1011, and the slide cover 405 is provided with a slide groove, and the guide portion 701 is accommodated in the slide groove;

[0098] The sliding cover 405 is used to slide along the guide portion 701, slide to the first end of the guide portion 701 to cover the live wire input conductive sheet L and the neutral wire input conductive sheet N, and slide to the second end of the guide portion 701 to expose the live wire input conductive sheet L and the neutral wire input conductive sheet N;

[0099] like Figure 4 as well as Figure 7aAs shown, the socket side shell 407 is provided with a limiting portion 702, and the limiting portion 702 is arranged close to the sliding cover 405. The limiting portion 702 is used to limit the sliding cover 405 to the first end of the guide portion 701 when the sliding cover 405 slides to the first end of the guide portion 701.

[0100] For example, Figure 7b As shown, when the live wire input and the neutral wire input are not needed, the sliding cover 405 can be closed to cover the live wire input conductive sheet L and the neutral wire input conductive sheet N, which can reduce the clearance between the live wire input conductive sheet L and the neutral wire input conductive sheet N and other devices, so that the output socket can be closely arranged with other electrical devices, which is convenient for the miniaturized design of the uninterruptible power supply and improves the safety of the power supply;

[0101] In addition, closing the sliding cover 405 can prevent dust or other foreign matter from falling in and causing poor contact or short circuit problems.

[0102] For example, Figure 7c As shown, when wiring is required, the sliding cover 405 can be slid open to connect the wires directly. In addition, even in the process of opening the sliding cover 405, foreign matter originally falling on the surface of the sliding cover 405 will not fall onto the live wire input conductive sheet L and the neutral wire input conductive sheet N.

[0103] Based on the technical solution in this embodiment, when the live wire input and the neutral wire input are not needed, the sliding cover slides to the first end of the guide part to cover the live wire input conductive sheet and the neutral wire input conductive sheet, thereby preventing dust or other foreign matter from falling in, reducing the clearance distance with other equipment, and allowing the output socket to be closely arranged with other electrical equipment. In addition, the design of the limiting part can prevent the sliding cover from sliding out and falling off.

[0104] In a possible embodiment, Figure 4 As shown, the housing of each multi-position output socket further includes a cover plate 409 and a socket front plate 406. The socket front plate 406 is provided with a plurality of sockets, and a third opening K3 is provided on a side away from the plurality of sockets. The third opening K3 is arranged opposite to the first copper bar output member T1 and the second copper bar output member T2. The cover plate 409 is covered on the third opening K3, and the cover plate 409 is hinged to the socket front plate 406 (as shown in FIG. Figure 8a as well as Figure 8b As shown, the rotating shaft 802 passes through the side wall of the socket front plate 406 and the side wall of the cover plate 409 to achieve hinge connection);

[0105] The cover plate 409 is used to be buckled in the third opening K3 to cover the first copper bar output member T1 and the second copper bar output member T2, and to be separated from the third opening K3 to expose the Figure 8c The first copper bar output component T1 and the second copper bar output component T2 are shown.

[0106] For example, Figure 8a As shown, the cover plate 409 is snap-fitted into the third opening K3 to prevent foreign matter from falling in. To further ensure the sealing of the socket, the cover plate 409 can also be inserted into the third opening K3. Figure 8a as well as Figure 8b The screws 801 shown further fix the cover 409. In addition, the cover 409 can be insulated and electrically isolated using plastic materials to prevent technicians from accidentally touching it.

[0107] For example, when there is a need for wiring, the technician can open the cover 409 to connect the wires. In this embodiment of the application, the technician can open the cover 409 to connect the wires. Figure 8b As shown, a spring piece 803 may also be provided, and when the technician removes the screw 803 , the spring piece 803 automatically pops open the cover plate 409 .

[0108] Based on the technical solution in this embodiment, the cover plate 409 is snapped into the third opening K3 of the socket front plate 406 to prevent foreign objects from falling in and prevent people from accidentally getting electric shocks. The cover plate 409 is opened and separated from the third opening K3 of the socket front plate 406 to facilitate wiring for technicians.

[0109] In a possible embodiment, Figure 8a As shown, a first disassembly window CX1 and a second disassembly window CX2 are provided on one side of the cover plate 409 away from the hinge.

[0110] Understandable, such as Figure 8a As shown, the rotating shaft 802 at the hinge passes through the cover plate 409 , so it is not convenient to set a disassembly window at a position of the cover plate close to the rotating shaft 802 .

[0111] The first disassembly window CX1 is used for disassembly to allow the cables connected to the first copper busbar output piece T1 to extend out, and the second disassembly window CX2 is used for disassembly to allow the cables connected to the second copper busbar output piece T2 to extend out.

[0112] For example, when the copper busbar needs to be wired out, the technician can open the cover, connect the copper busbar output and the cable, remove the two disassembly windows, extend the cable through the disassembly windows, and further, close the cover 409 to prevent foreign objects from falling in.

[0113] Based on the technical solution of this embodiment, the wiring can be avoided by reserving a disassembly window design, so that during the output of the copper busbar, the cover plate 409 can continue to be fastened to the opening of the socket front plate 406 to prevent foreign objects from falling in and prevent technicians from getting electric shock.

[0114] In summary, the embodiment of the present application provides an uninterruptible power supply device, the input socket of the uninterruptible power supply device is welded on the board, and the multiple output sockets of the uninterruptible power supply device are cascaded between each socket through a copper bus, thereby reducing the number of cables required for the device and shortening the circuit length;

[0115] In addition, the protective conductive sheet in the embodiment of the present application is exposed outside the socket and connected to the device housing, thereby realizing housing grounding protection;

[0116] Furthermore, the embodiments of the present application also provide dust and electric shock prevention designs for the sockets of the uninterruptible power supply equipment, thereby improving the safety of the equipment.

[0117] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
