Description

Technical Field

[0001] This application relates to the field of data center technology, and more specifically, to a rack-mounted power distribution unit assembly and a data center. Background Technology

[0002] Currently, rack power distribution units (RPDUs) commonly used in data centers are usually located at the rear of the rack. However, as the power density of IT racks increases and servers become deeper, the number of cables inside the racks is also increasing, leading to a shortage of cabling space.

[0003] Furthermore, with the popularization and promotion of cold plate liquid-cooled server technology, liquid-cooled IT cabinets have higher power density and more cables, requiring more cabling space. However, liquid-cooled servers are typically deeper than traditional servers (some liquid-cooled servers on the market are now up to 950mm deep). In addition, liquid-cooled servers require the installation of liquid cooler distributors within the cabinet, and there are minimum bending radius requirements for the liquid cooling pipes on the distributors. This further complicates the depth space of IT cabinets, leaving less room for cable routing and making cable management more difficult.

[0004] Meanwhile, in another scenario, when the RPDU itself fails and a temporary RPDU is needed to ensure power supply to the load, there is no space left to connect a temporary RPDU for maintenance. Utility Model Content

[0005] This application provides a rack-mounted power distribution unit (PDU) assembly and a data center. The PDU can move along a first direction and rotate around a rotation axis parallel to the vertical direction, offering flexible installation and adaptability to assembly in different positions and directions. It allows for flexible adjustment of power wiring relationships with servers, enabling rack-mounted deployment even under uncertain circumstances and ensuring compatibility with various delivery scenarios later. This PDU assembly addresses emergency and temporary maintenance requirements, facilitating the installation and securing of temporary PDUs during emergency maintenance. After the PDU is installed in the rack via the PDU assembly, it is positioned between two crossbeams at the top and bottom of the rack, eliminating the need to increase rack depth, saving rack costs and data center space, thereby reducing data center costs.

[0006] This application is achieved through the following technical solution:

The first connector is disposed in the mounting groove and the first mounting hole, and the first locking member is configured to cooperate with the first connector to lock the mounting component to the mounting frame or unlock the mounting component from the mounting frame. When the mounting component is unlocked from the mounting frame, the mounting component can move relative to the mounting frame along the first direction, and the mounting component can rotate relative to the mounting frame about a rotation axis parallel to the vertical direction.

[0008] According to the rack-mounted power distribution unit assembly of this application embodiment, after the rack-mounted power distribution unit is installed on the crossbeam of the cabinet, the position of the rack-mounted power distribution unit can be adjusted in a first direction, and the orientation of the rack-mounted power distribution unit can be adjusted around a rotation axis parallel to the vertical direction.

[0023] According to some embodiments of this application, the mounting assembly further includes a mounting bracket disposed between the first connecting portion and the mounting frame. The mounting bracket is provided with a second mounting hole corresponding to the first mounting hole. The first connecting member is configured to be disposed in the mounting groove, the second mounting hole, and the first mounting hole. In the vertical direction, the orthographic projection of the first connecting portion falls into the orthographic projection of the mounting bracket.

[0024] In the above scheme, the mounting bracket is set between the first connecting part and the mounting frame, providing an assembly base for the mounting plate and facilitating the assembly of the mounting plate and the mounting frame; at the same time, the orthographic projection of the first connecting part falls within the orthographic projection of the mounting bracket, which ensures that the mounting plate and the mounting bracket have a large connection area after the mounting plate rotates around the rotation axis.

[0025] According to some embodiments of this application, the second connecting portion is provided with a plurality of third mounting holes, which are distributed in a matrix along the length and width directions of the second connecting portion, and the length direction of the second connecting portion is parallel to the vertical direction.

[0028] In the above scheme, the addition of two third connection parts can enhance the overall strength of the mounting plate and facilitate the improvement of the connection stability between the rack-mounted power distribution unit and the mounting frame.

[0029] According to some embodiments of this application, the first connecting part, the second connecting part, and the two third connecting parts are integrally formed.

[0030] In the above scheme, the first connecting part, the second connecting part and the two third connecting parts are integrally formed, which is convenient for processing and manufacturing, and makes the mounting plate have high overall strength.

[0031] According to some embodiments of this application, the first connector has a threaded section, and the first locking member is a ram's nut, which is configured to engage with the threaded section.

[0032] In the above scheme, the ram's nut is threaded into the first connecting piece, which facilitates tool-free installation and flexible assembly.

The rack-mounted power distribution unit can move along a first direction and rotate about a rotation axis parallel to the vertical direction, which is flexible in installation and adaptable to assembly in different positions and directions. The power wiring relationship between the unit and the server can be flexibly adjusted, thereby enabling rack-mounted deployment in uncertain situations and compatibility with various delivery scenarios later.

[0053] The structure of the rack-mounted power distribution unit assembly according to an embodiment of this application is described below with reference to the accompanying drawings.

[0054] Please refer to Figures 1 to 4 This application provides a rack-mounted power distribution unit assembly 100, which is applied to a data center cabinet 200. The cabinet 200 includes a crossbeam 21, and the rack-mounted power distribution unit assembly 100 is mounted on the crossbeam 21 so that the rack-mounted power distribution unit 300 is fixed to the crossbeam 21 by the rack-mounted power distribution unit assembly 100.

[0055] Please refer to Figures 1 to 4The rack-mounted power distribution unit assembly 100 includes a mounting frame 11, a mounting component 12, and a first locking component 13. The mounting frame 11 is mounted on a crossbeam 21; wherein the mounting frame 11 has a mounting groove 111 extending along a first direction X, the first direction X being configured parallel to the length direction of the crossbeam 21. The mounting component 12 is configured to connect to the rack-mounted power distribution unit 300, and the mounting component 12 is correspondingly disposed to the mounting frame 11. The rack-mounted power distribution unit 300 is disposed along a vertical direction Z. The mounting component 12 has a first mounting hole 121 corresponding to the mounting groove 111. The first locking component 13 includes a first connector 131 and a first locking member 132. The first connector 131 is disposed in the mounting groove 111 and the first mounting hole 121. The first locking member 132 is configured to cooperate with the first connector 131 to lock the mounting component 12 to the mounting frame 11, or to unlock the mounting component 12 from the mounting frame 11. When the mounting component 12 is unlocked from the mounting frame 11, the mounting component 12 can move relative to the mounting frame 11 along the first direction X, and the mounting component 12 can rotate relative to the mounting frame 11 about a rotation axis parallel to the vertical direction Z.

[0056] For example, when the first locking member 132 is locked to the first connecting member 131, the mounting assembly 12 is locked to the mounting frame 11 and cannot move relative to the mounting frame 11. In this case, the rack-mounted power distribution unit 300 can be fixed to the two crossbeams 21. Alternatively, when the first locking member 132 is unlocked from the first connecting member 131, the first locking member 132 can be separated from the first connecting member 131, or it can remain in place. However, the mounting assembly 12 can move or rotate relative to the mounting frame 11 to adjust the position and angle of the rack-mounted power distribution unit 300.

[0057] In some embodiments, the rack 200 includes two crossbeams 21 disposed on the same side, at the top and bottom. A rack-mounted power distribution unit assembly 100 is mounted on these two crossbeams 21, such that the rack-mounted power distribution unit 300 is fixed to the two crossbeams 21 via the rack-mounted power distribution unit assembly 100. This assembly method utilizes the space between the two crossbeams 21 at the top and bottom, reducing the space occupied by the rack-mounted power distribution unit 300 inside the rack 200, thus eliminating the need for a deeper rack. Two mounting frames 11 are used to correspond one-to-one with the two crossbeams 21, each mounting frame 11 being mounted on one crossbeam 21; two mounting assemblies 12 are configured to connect to both ends of the rack-mounted power distribution unit 300 along its length, each mounting assembly 12 corresponding to one mounting frame 11.

[0058] A mounting component 12 and a mounting frame 11 can constitute a mounting unit. The rack-mounted power distribution unit assembly 100 includes two mounting units distributed at both ends of the rack-mounted power distribution unit 300 along its length, so as to facilitate the mounting of the rack-mounted power distribution unit 300 to the two crossbeams 21 at the top and bottom of the cabinet 200.

[0059] The first connector 131 can be a bolt, pin, or other component. The first connector 131 can be disposed in the mounting groove 111 and the first mounting hole 121 to constrain the mounting assembly 12 to move relative to the mounting frame 11 in a plane perpendicular to the central axis of the first connector 131. The mounting assembly 12 can be locked to the mounting frame 11 by locking the first locking member 132 with the first connector 131.

[0060] In some embodiments, when adjusting the position and angle of the rack-mounted power distribution unit 300, the first locking member 132 can be unlocked from the first connecting member 131. At this time, the first locking member 132 can be connected to the first connecting member 131 but the first locking member 132 and the first connecting member 131 are not separated. Adjusting the position or angle of the mounting assembly 12 relative to the mounting frame 11 allows for the adjustment of the position and angle of the rack-mounted power distribution unit 300. This adjustment method improves adjustment efficiency and shortens adjustment time. It should be noted that the axis of rotation of the mounting assembly 12 relative to the mounting frame 11 can be the central axis of the first connecting member 131.

[0061] According to the rack-mounted power distribution unit assembly 100 of this application embodiment, after the rack-mounted power distribution unit 300 is installed on the two crossbeams 21 located at the top and bottom of the rack 200, the position of the rack-mounted power distribution unit 300 can be adjusted in the first direction X, and the orientation of the rack-mounted power distribution unit 300 can be adjusted around a rotation axis parallel to the vertical direction Z. The power wiring relationship with the server can be flexibly adjusted, thereby enabling the rack 200 to be deployed first under uncertain circumstances, and ensuring compatibility with later deployments. Various delivery scenarios; the rack-mounted power distribution unit assembly 100 can solve emergency and temporary maintenance requirements, solving the installation and fixation of the temporary rack-mounted power distribution unit 300 during emergency maintenance; at the same time, after the rack-mounted power distribution unit 300 is installed in the rack 200 through the rack-mounted power distribution unit assembly 100, the rack-mounted power distribution unit 300 is located between the two crossbeams 21 at the top and bottom of the rack 200, without increasing the depth of the rack 200, saving the cost of the rack 200, saving data center space, and thus reducing the cost of the data center.

[0062] Please refer to Figures 2 to 4 According to some embodiments of this application, the mounting groove 111 is an elongated hole extending along the first direction X.

[0063] The mounting slot 111 is an elongated hole, which is a through hole provided on the mounting frame 11 to facilitate the insertion of the first connector 131.

[0064] The elongated hole can be understood as a racetrack shape, which includes a straight section and two circular arc sections, with the straight section connecting the two circular arc sections.

[0065] After the first connector 131 is disposed in the mounting slot 111, the position of the first connector 131 in the mounting slot 111 determines the position of the mounting assembly 12 in the first direction X, so as to determine the position of the rack-mounted power distribution unit 300 in the first direction X.

[0066] In the above scheme, the elongated hole structure is simple and easy to process, and the first connector 131 moves smoothly in the elongated hole, which facilitates the adjustment of the connection position between the mounting assembly 12 and the mounting frame 11 along the first direction X.

[0067] Please refer to Figures 1 to 4 According to some embodiments of this application, the mounting frame 11 is a hollow structure, and a receiving cavity 112 is formed inside the mounting frame 11. A portion of the first connector 131 is disposed in the receiving cavity 112. The mounting frame 11 has a first wall 11a, which faces the mounting assembly 12. A mounting groove 111 is disposed on the first wall 11a and penetrates the first wall 11a along its thickness direction. The mounting groove 111 communicates with the receiving cavity 112. The thickness direction of the first wall 11a is parallel to the vertical direction Z. A first opening 113 is provided at one end of the mounting frame 11 along the second direction Y. The first opening 113 is used to allow the first connector 131 to enter the receiving cavity 112. The second direction Y, the first direction X, and the vertical direction Z are perpendicular to each other.

[0068] The mounting frame 11 has a receiving cavity 112 inside. The mounting frame 11 can be spliced ​​from multiple plate-like structures. For example, the mounting frame 11 can be formed by welding multiple plate-like structures, or the mounting frame 11 can be formed by bending a plate.

[0069] A portion of the first connector 131 is disposed within the receiving cavity 112. The first connector 131 includes a body and a limiting portion, which is disposed within the receiving cavity 112 to restrict the separation of the first connector 131 from the mounting frame 11. For example, when the first connector 131 is a bolt and the first locking member 132 is a nut, the limiting portion can be the head of the bolt, with the threaded section of the bolt extending out of the receiving cavity 112 to connect with the nut.

[0070] The first wall 11a is the wall portion of the mounting frame 11 facing the mounting assembly 12, and the first wall 11a is closer to the mounting assembly 12 than the other walls of the mounting frame 11. When the rack-mounted power distribution unit 300 is mounted on the cabinet 200 via the rack-mounted power distribution assembly, the first wall 11a can be the wall portion of the mounting frame 11 facing away from the crossbeam 21.

[0071] The mounting slot 111 communicates with the receiving cavity 112 so that the first connector 131 can extend from the receiving cavity 112 and connect with the mounting assembly 12, thereby saving the assembly space occupied by the first connector 131.

[0072] The mounting frame 11 can be in the shape of a cuboid. The length of the mounting frame 11 is parallel to the first direction X, and the width of the mounting frame 11 is parallel to the second direction Y. The second direction Y can be parallel to the width direction of the crossbeam 21.

[0073] The first opening 113 is located at one end of the mounting frame 11 in the second direction Y. When the first connector 131 is assembled with the mounting frame 11 and the mounting assembly 12, the first connector 131 can enter the receiving cavity 112 through the first opening 113. Then, one end of the first connector 131 extends out of the receiving cavity 112 through the mounting groove 111 to enter the first mounting hole 121 of the mounting assembly 12 and connect with the first locking member 132 to realize the assembly of the mounting assembly 12 and the mounting frame 11.

[0074] In the above scheme, the mounting frame 11 is a hollow structure, which makes the mounting frame 11 lighter and saves materials, thus reducing costs; a part of the first connector 131 is disposed in the receiving cavity 112, which facilitates the accommodation of the first connector 131 and reduces the space occupied by the first connector 131; the first wall 11a is configured to face the mounting assembly 12, and the mounting groove 111 is disposed in the first wall 11a, so as to facilitate the adjustment of the connection position between the mounting assembly 12 and the mounting frame 11, and the position adjustment is flexible.

[0075] Please refer to Figures 2 to 4 According to some embodiments of this application, the mounting frame 11 includes a frame body 110 and a flange 114. The frame body 110 is used to overlap with the crossbeam 21. The flange 114 is formed on the edge of the frame body 110 in the second direction Y and extends toward the side opposite to the mounting assembly 12. The flange 114 is used to connect with the crossbeam 21.

[0076] The frame body 110 forms the foundation of the mounting frame 11. The frame body 110 is used to be mounted on the crossbeam 21, and the frame body 110 and the crossbeam 21 have a large connection area. The mounting groove 111 is provided in the frame body 110 to facilitate connection with the mounting component 12.

[0077] A flange 114 is formed on the edge of the frame body 110 in the second direction Y. The flange 114 extends toward the side opposite to the mounting assembly 12 and is used to connect with the side of the crossbeam 21 in the second direction Y. For example, the flange 114 can be integrally formed with the frame body 110, or the flange 114 can be formed by folding the edge of the frame body 110 in the second direction Y toward the side opposite to the mounting assembly 12.

[0078] In the above scheme, the flange 114 can increase the connection area between the mounting frame 11 and the crossbeam 21, so as to improve the connection stability between the mounting frame 11 and the crossbeam 21.

[0079] Please refer to Figures 2 to 4 According to some embodiments of this application, the frame body 110 includes a first wall 11a, a second wall 11b, a third wall 11c, and two fourth walls 11d. The second wall 11b is disposed opposite to the first wall 11a in the vertical direction Z and is used to connect with the crossbeam 21. The third wall 11c is located at the same end of the first wall 11a and the second wall 11b in the second direction Y. The two fourth walls 11d are disposed opposite to each other in the first direction X. The first wall 11a, the second wall 11b, the third wall 11c, and the two fourth walls 11d form a receiving cavity 112. The flange portion 114 is located at both ends of the second wall 11b in the second direction Y and is connected to the second wall 11b and extends in a direction away from the first wall 11a.

[0080] The frame body 110 can be a hollow cuboid, and a first opening 113 is formed at one end in the second direction Y. After the rack-mounted power distribution unit 300 is assembled into the cabinet 200, the first opening 113 can face the outside of the cabinet 200 so that the first connector 131 can enter the receiving cavity 112.

[0081] The first wall 11a, the second wall 11b, and the two fourth walls 11d form a first opening 113 at one end in the second direction Y. The first opening 113 is positioned opposite to the third wall 11c in the second direction Y.

[0082] The flange 114 is connected to the edge of the second wall 11b that forms one end of the first opening 113, and the second wall 11b is connected to the crossbeam 21.

[0083] In the above scheme, the flange 114 is connected to the second wall 11b and extends in a direction away from the first wall 11a, which facilitates processing and manufacturing.

[0084] According to some embodiments of this application, the first wall 11a, the second wall 11b, the third wall 11c, the two fourth walls 11d, and the flange portion 114 are integrally formed.

[0085] In some embodiments, the mounting frame 11 is made of metal, which gives the mounting frame 11 high strength. For example, the mounting frame 11 can be made of steel, aluminum alloy, etc.

[0086] The mounting frame 11 can be formed by bending a metal plate. The first wall 11a is welded to two fourth walls 11d at both ends in the first direction X, and the fourth wall 11d is welded to the third wall 11c, so that the mounting frame 11 has high overall strength.

[0087] In the above scheme, the first wall 11a, the second wall 11b, the third wall 11c, the two fourth walls 11d and the flange 114 can be formed by bending a metal plate, which is convenient for processing and manufacturing, and also makes the mounting frame 11 have high overall strength and easy to provide support.

[0088] Please refer to Figures 2 to 4 According to some embodiments of this application, the mounting assembly 12 includes a mounting plate 122, which includes a first connecting portion 122a and a second connecting portion 122b. The first connecting portion 122a and the second connecting portion 122b are arranged in an L-shape. The first connecting portion 122a is correspondingly arranged with the mounting frame 11 and is parallel to the mounting frame 11. A first mounting hole 121 is provided in the first connecting portion 122a. The second connecting portion 122b is located on the side of the first connecting portion 122a away from the mounting frame 11. The second connecting portion 122b is arranged in the vertical direction Z and is used to connect with the rack-mounted power distribution unit 300.

[0089] Mounting plate 122 can be a metal plate, and the material of mounting plate 122 can be steel, aluminum alloy, etc.

[0090] The first connecting part 122a and the second connecting part 122b can be formed by bending the sheet metal.

[0091] During assembly, the first connecting part 122a can be fitted to the first wall 11a of the mounting frame 11 so that the first connecting part 122a and the first wall 11a are stably connected.

[0092] The first connecting part 122a is arranged parallel to the first wall 11a of the mounting frame 11, and the thickness direction of the first connecting part 122a is parallel to the vertical direction Z.

[0093] The first mounting hole 121 is provided in the first connecting part 122a, and the first mounting hole 121 penetrates the first connecting part 122a in the vertical direction Z.

[0094] The second connecting part 122b and the first connecting part 122a form a receiving space for accommodating the first locking member 132. The first locking member 132 can be disposed in the receiving space to reduce space occupation and avoid interference with other components.

[0095] In the above scheme, the first connecting part 122a is connected to the mounting frame 11, and the second connecting part 122b is used to connect to the rack-mounted power distribution unit 300, which facilitates the assembly of the rack-mounted power distribution unit 300 and the mounting frame 11. The rack-mounted power distribution unit 300 can be arranged vertically between two crossbeams 21 to reduce the space occupied inside the cabinet 200. The first connecting part 122a and the second connecting part 122b can be integrally formed to ensure high connection reliability between the first connecting part 122a and the second connecting part 122b.

[0096] Please refer to Figures 2 to 4 According to some embodiments of this application, the mounting assembly 12 further includes a mounting bracket 123, which is disposed between the first connecting portion 122a and the mounting frame 11. The mounting bracket 123 is provided with a second mounting hole corresponding to the first mounting hole 121. The first connecting member 131 is configured to be disposed in the mounting groove 111, the second mounting hole and the first mounting hole 121. Along the vertical direction Z, the orthographic projection of the first connecting portion 122a falls into the orthographic projection of the mounting bracket 123.

[0097] The mounting bracket 123 is disposed between the first connecting part 122a and the mounting frame 11. The first connecting part 122a and the first wall 11a are connected by the mounting bracket 123, so as to improve the connection stability between the first connecting part 122a and the first wall 11a. At the same time, it can also shorten the distance between the two oppositely arranged mounting plates 122 in the vertical direction Z, so as to accommodate the shorter rack-mounted power distribution unit 300.

[0098] The second mounting hole is provided corresponding to the first mounting hole 121 and is coaxial with the first mounting hole 121. During the assembly process, the first connecting member 131 passes through the mounting groove 111, the second mounting hole and the first mounting hole 121 in sequence to connect with the first locking member 132.

[0099] Along the vertical direction Z, the orthographic projection of the first connecting part 122a falls into the orthographic projection of the mounting frame 123. The mounting frame 123 and the first connecting part 122a have a large overlap area. When the mounting plate 122 rotates relative to the mounting frame 123 around the first connecting member 131, the first connecting part 122a and the mounting frame 123 can have a large connection area.

[0100] When adjusting the orientation of the rack-mounted power distribution unit 300, the rack-mounted power distribution unit 300 and the mounting plate 122 can be adjusted synchronously. That is, the angle of the mounting plate 122 relative to the mounting bracket 123 is adjusted, the rack-mounted power distribution unit 300 is locked to the mounting plate 122, and the positions of the mounting bracket 123 and the mounting frame 11 remain unchanged. For example, the first locking member 132 and the first connecting member 131 are unlocked, but the first connecting member 131 passes through the mounting groove 111, the second mounting hole and the first mounting hole 121. After rotating the mounting plate 122 and the rack-mounted power distribution unit 300 and adjusting them to the preset orientation, the first locking member 132 and the first connecting member 131 are locked, thereby completing the orientation adjustment of the rack-mounted power distribution unit 300.

[0101] In the above scheme, the mounting bracket 123 is disposed between the first connecting part 122a and the mounting frame 11, providing an assembly base for the mounting plate 122 and facilitating the assembly of the mounting plate 122 and the mounting frame 11; at the same time, the orthographic projection of the first connecting part 122a falls within the orthographic projection of the mounting bracket 123, which ensures that after the mounting plate 122 rotates around the rotation axis, the mounting plate 122 and the mounting bracket 123 have a large connection area.

[0102] In some embodiments, the mounting bracket 123 has a hollow structure to reduce weight and save materials. For example, the mounting bracket 123 can be formed by bending or splicing sheet metal, which can have a lighter weight while meeting strength requirements.

[0103] In some embodiments, the mounting bracket 123 and the mounting plate 122 are fixed together to improve the overall strength of the mounting bracket 123 and the mounting plate 122. When the mounting bracket 123 and the mounting plate 122 are fixed together, the mounting bracket 123 and the mounting plate 122 as a whole can rotate about the rotation axis relative to the mounting frame 11.

[0104] Please refer to Figure 3 and Figure 4 According to some embodiments of this application, the second connecting portion 122b is provided with a plurality of third mounting holes 124, which are distributed in a matrix along the length and width directions of the second connecting portion 122b, and the length direction of the second connecting portion 122b is parallel to the vertical direction Z.

[0105] Multiple third mounting holes 124 can be set at equal intervals, which facilitates processing and manufacturing.

[0106] The third mounting hole 124 can be circular, square, or irregularly shaped. Optionally, the third mounting hole 124 is circular.

[0107] The third mounting hole 124 can penetrate the second connecting portion 122b along the thickness direction of the second connecting portion 122b.

[0108] In the above scheme, the arrangement of multiple third mounting holes 124 provides more mounting positions to accommodate rack-mounted power distribution units 300 of different lengths, thus broadening the application range.

[0109] Please refer to Figure 3 and Figure 4 According to some embodiments of this application, the mounting plate 122 further includes two third connecting portions 122c. The two third connecting portions 122c are respectively disposed at both ends of the width direction of the second connecting portion 122b. The two third connecting portions 122c are disposed on the side of the second connecting portion 122b facing the first connecting portion 122a. The two third connecting portions 122c and the second connecting portion 122b form a U-shaped structure. The first connecting portion 122a is welded to the two third connecting portions 122c.

[0110] like Figure 3 As shown, the width direction of the second connecting part 122b is parallel to the second direction Y.

[0111] In some embodiments, the third connecting portion 122c and the second connecting portion 122b are connected at their ends in the width direction in various ways. For example, the third connecting portion 122c and the second connecting portion 122b are welded together, or the third connecting portion 122c and the second connecting portion 122b are integrally formed.

[0112] The third connecting part 122c extends along the length direction of the second connecting part 122b to the first connecting part 122a. The third connecting part 122c is welded to the first connecting part 122a so that the mounting plate 122 has high overall strength.

[0113] In some embodiments, the two third connecting portions 122c and the second connecting portion 122b form a U-shaped structure. Along the width direction of the second connecting portion 122b, the first locking member 132 is located between the two third connecting portions 122c, reducing the risk of interference between the first locking member 132 and other components.

[0114] In other embodiments, the first locking member 132 is disposed within the receiving cavity 112, and a portion of the first connector 131 (such as the head of a bolt) is located in the receiving space.

[0115] In the above scheme, the provision of two third connecting parts 122c can enhance the overall strength of the mounting plate 122 and facilitate the improvement of the connection stability between the rack-mounted power distribution unit 300 and the mounting frame 11.

[0116] According to some embodiments of this application, the first connecting portion 122a, the second connecting portion 122b, and the two third connecting portions 122c are integrally formed.

[0117] In some embodiments, the first connecting portion 122a, the second connecting portion 122b, and the two third connecting portions 122c can be formed from a single sheet of material by bending, or the first connecting portion 122a, the second connecting portion 122b, and the two third connecting portions 122c can be formed by casting or integral extrusion.

[0118] In the above scheme, the first connecting part 122a, the second connecting part 122b and the two third connecting parts 122c are integrally formed, which is convenient for processing and manufacturing, and makes the mounting plate 122 have high overall strength.

[0119] In the above embodiments, the mounting plate 122, mounting bracket 123, and mounting frame 11 can all be metal parts, such as aluminum alloy parts, stainless steel parts, etc., to give them high strength.

[0120] Please refer to Figure 4 According to some embodiments of this application, the first connector 131 has a threaded section, and the first locking member 132 is a ram's nut, which is configured to engage with the threaded section.

[0121] The first connector 131 can be a bolt, or the first connector 131 can be a pin with a threaded section.

[0122] A ram's horn nut is a common fastener used to connect bolts. It gets its name from its ram's horn-like shape and is typically used in applications requiring shock absorption and anti-loosening properties. The manufacture of ram's horn nuts must comply with the mechanical industry standard JB / T 3411.63-1999.

[0123] When assembling the nut and the threaded section, the nut can be manually tightened to achieve tool-free installation, which improves assembly efficiency.

[0124] In the above scheme, the ram's nut is threaded into the first connecting piece 131, which facilitates tool-free installation and flexible assembly.
