[0035] In existing technologies, as data centers expand in scale, server racks increasingly demand high-power-density power distribution. Traditional power supply devices use three-phase busbars arranged along the height, but there are large gaps between the busbars and between them and the casing, resulting in numerous exposed areas of live metal. Maintenance personnel face the risk of accidentally touching live components when plugging or unplugging power supplies or performing routine checks, significantly increasing the risk of electric shock.

[0036] To address the aforementioned problems, this utility model proposes a power supply device 1000 for server racks. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 A schematic diagram of an embodiment of the power supply device 1000 for server racks provided by this utility model.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 This utility model proposes a power supply device 1000 for a server cabinet, including a housing 1, three busbars 2, two insulating plates 3, three insulating components 4, and at least three baffles 5; the length direction of the housing 1 is defined as the first direction, the width direction of the housing 1 as the second direction, and the height direction of the housing 1 as the third direction; the three busbars 2 are all extended along the first direction and are spaced apart along the second direction; the two insulating plates 3 are all disposed on the housing 1 and are extended along the first direction; an insulating plate 3 is sandwiched between every two busbars 2; the end of the insulating plate 3 away from the housing 1 protrudes from the busbar 2 in the third direction; each insulating component 4 is sleeved in a busbar 2 at the end away from the housing 1 in the third direction; each baffle 5 is assembled and connected to a busbar 2 and is assembled and connected to the corresponding insulating component 4 to prevent the insulating component 4 from moving relative to the busbar 2 in the first direction.

[0038] The outer casing 1 serves as the main load-bearing structure, with its length, width, and height forming a spatial coordinate system. The busbar 2's extension along its length helps reduce line impedance. The design of the insulating plate 3 extending beyond the busbar 2 creates a physical isolation barrier. The insulating component 4 is fitted onto the top of the busbar 2, forming an insulating protective layer. The baffle 5 is detachably connected to the busbar 2 and the insulating component 4 via screws 9. The outer casing 1 forms a mounting groove for installing the busbar 2. The direction perpendicular to the first direction on the plane where the bottom wall of the mounting groove lies is the second direction, and the direction perpendicular to the first direction on the plane where either of the two side walls of the mounting groove lies is the third direction.

[0039] Specifically, three busbars 2 are arranged parallel to each other along their width, and two insulating plates 3 are inserted into the gaps between adjacent busbars 2. The tops of the insulating plates 3 extend beyond the surface of the busbar 2 in the height direction, forming a protective strip covering the conductive area. After an insulating element 4 is fitted onto the top of each busbar 2, it is constrained at both ends in the length direction by baffles 5. The baffles 5 are connected to the busbar 2 and the insulating element 4 by screws 9, forming a mechanical limiting structure to prevent the insulating element 4 from slipping off. This layout ensures that the live conductor is wrapped in multiple layers of insulating material, and the areas that the hand touches during operation and maintenance are all non-conductive parts.

[0040] The insulating plate 3 provides longitudinal shielding to the busbar 2 in the third direction and, together with the insulating component 4 fitted onto the top of the busbar 2, forms a lateral covering, reducing the previously exposed live area. Simultaneously, the baffle 5, with its assembled connection, mechanically limits the insulating component 4 and the busbar 2, preventing slippage or detachment of the insulating component 4 in the first direction and maintaining the integrity of the insulation coverage throughout its length, thereby reducing the probability of electric shock accidents. The baffle 5 structure ensures that the insulating component 4 does not shift during long-term use, maintaining a stable state of insulation protection. This multi-level protection design fundamentally eliminates the possibility of accidental contact with live parts while maintaining the maintainability of the power supply device.

[0041] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, a limiting protrusion 31 is provided on both sides of the insulating plate 3 near the outer shell 1 facing the second direction; the two adjacent busbars 2 of each insulating plate 3 respectively abut against the two limiting protrusions 31 on the side away from the outer shell 1.

[0042] The limiting protrusion 31 refers to a raised structure extending from the body of the insulating plate 3 towards both sides in the second direction. It can be implemented by injection molding or machining. Its function is to mechanically constrain the lateral displacement of the busbar 2. The two adjacent busbars 2 respectively abut against the side of the limiting protrusion 31 away from the outer shell 1. This means that the two edges of the busbar 2 in the second direction are in contact with the corresponding surfaces of the limiting protrusion 31. This contact relationship can limit the displacement of the busbar 2 in the second direction, while maintaining a fixed distance between adjacent busbars 2.

[0043] Specifically, when the insulating plate 3 extends along the first direction and is installed inside the housing 1, its two ends near the bottom of the housing 1 form a lateral blocking structure through the limiting protrusions 31. When the two busbars 2 are respectively clamped on both sides of the insulating plate 3, the two edges of the busbars 2 in the second direction are restricted by the outer surface of the limiting protrusions 31, preventing the busbars 2 from displacing in the second direction. Thus, during equipment operation or maintenance, even if subjected to external forces, the busbars 2 can still maintain a stable relative position, avoiding the expansion of the exposed area of ​​the live conductor due to displacement.

[0044] The double-sided mechanical constraint formed by the limiting protrusion 31 eliminates the degree of freedom of the busbar 2 in the second direction, effectively restricting the lateral displacement of the busbar 2 and preventing the live conductor from being exposed outside the insulation plate 3 due to positional displacement, thereby reducing the risk of maintenance personnel accidentally touching live parts. At the same time, the design of the limiting protrusion 31 being integrally formed with the insulation plate 3 simplifies the assembly process, achieving reliable limiting without the need for additional fixing parts.

[0045] Please refer to Figure 5In one embodiment of this utility model, the opposite side walls of the outer shell 1 and the two insulating plates 3 are formed with through threaded holes 1a, and the three busbars 2 are formed with through holes; the power supply device 1000 for the server cabinet also includes a screw 7 and a filler 6, the filler 6 is filled in the through hole, the filler 6 is formed with a mounting hole 6a corresponding to the threaded hole 1a, and the screw 7 passes through the mounting hole 6a and is screwed into the threaded hole 1a.

[0046] In this design, threaded hole 1a refers to a hole structure with internal threads machined on the two side walls of the outer casing 1 and the insulating plate 3. This can be achieved using a drilling and tapping process, and is used to form a threaded fit with the screw 7. Through hole refers to a through hole 5a opened on the busbar 2, which can be achieved using a stamping or drilling process, and is used to accommodate the filler 6. Filler 6 refers to an adapter component embedded in the through hole, which can be injection molded from insulating material. Its internal mounting hole 6a is coaxially aligned with the threaded hole 1a, used to guide the screw 7 through and achieve a fixed connection. Screw 7 refers to a fastener with external threads, which can be machined from metal material and is screwed into the threaded hole 1a to achieve a mechanical connection between the outer casing 1, the insulating plate 3, and the busbar 2.

[0047] Specifically, during assembly, the filler 6 is pre-pressed into the through hole of the manifold 2, with its mounting hole 6a coaxial with the threaded holes 1a on both side walls of the housing 1 and the insulating plate 3. When the screw 7 passes through the mounting hole 6a of the filler 6 and is screwed into the threaded hole 1a, the housing 1, the insulating plate 3, and the manifold 2 are simultaneously pressed and fixed. Because the filler 6 fills the gap between the through hole and the screw 7, displacement of the manifold 2 due to vibration or external force is prevented, while the axial locking force of the threaded connection maintains a tight fit between the components.

[0048] By filling the gaps with filler 6 and forming a precise alignment, the fit between screw 7 and threaded hole 1a becomes more stable, effectively suppressing the relative displacement between components. This solves the problem of exposed live metal caused by the unstable connection between busbar 2 and housing 1. At the same time, the insulating properties of filler 6 block the conductive path between busbar 2 and housing 1, while the axial clamping force of the threaded connection eliminates the assembly gaps between components, thereby reducing the risk of accidental contact with live parts during operation and maintenance and improving the safety protection capability of the power supply device.

[0049] Please refer to Figure 5 In one embodiment of this utility model, the through hole formed by the busbar 2 in the middle is the first through hole 2a, and the two through holes formed by the busbars 2 on both sides are the second through holes 2b; the power supply device 1000 for the server cabinet includes two fillers 6, each filler 6 being filled in a second through hole 2b; the end of the filler 6 away from the first through hole 2a abuts against the outer shell 1.

[0050] The first through hole 2a refers to the through hole structure provided on the middle busbar 2, which can be implemented using a circular or rectangular hole shape, and is used to accommodate the screw 7 to pass through and connect to the outer casing 1. The second through hole 2b refers to the through hole structure provided on both side busbars 2.

[0051] Specifically, after the filler 6 is pressed into the second through hole 2b, its end away from the first through hole 2a forms a surface contact with the inner wall of the outer casing 1 through the abutting protrusion 61. When the screw 7 passes through the mounting hole 6a of the filler 6 and is locked with the threaded hole 1a of the outer casing 1, the two busbars 2 are clamped between the filler 6 and the insulating plate 3, thereby restricting their displacement in the second direction. Since the filler 6 is only provided in the second through hole 2b of the two busbars 2, the screw 7 passes through the first through hole 2a of the middle busbar 2, and there is a gap between the screw 7 and the hole wall of the first through hole 2a, thereby blocking the conductive path between the middle busbar 2 and the screw 7, improving the safety protection capability of the power supply device.

[0052] Please refer to Figure 5 In one embodiment of the present invention, the end of the filler 6 away from the first through hole 2a is formed with an abutting protrusion 61, and the side of the abutting protrusion 61 facing the first through hole 2a abuts against the adjacent busbar 2.

[0053] Among them, the abutting protrusion 61 refers to the protruding structure extending outward from the end of the filler 6. Specifically, it can be integrally formed with the filler 6 through injection molding process to increase the contact area with the adjacent busbar 2 and restrict the displacement of the filler 6 in the through hole.

[0054] Specifically, after the filler 6 is pressed into the second through hole 2b, its abutting protrusion 61 extends toward the first through hole 2a and contacts the side wall of the adjacent intermediate busbar 2. When the screw 7 passes through the mounting hole 6a of the filler 6 and is screwed into the threaded hole 1a of the housing 1, the abutting protrusion 61 is subjected to the reaction force of the intermediate busbar 2, causing the filler 6 to be bidirectionally limited within the second through hole 2b. Thus, the filler 6 cannot move in the second direction or disengage from the through hole in the third direction within the second through hole 2b, thereby ensuring the insulation stability between the busbar 2 and the housing 1.

[0055] By directly contacting the abutting protrusion 61 with the busbar 2, a mechanical interlocking structure is formed, which significantly improves the displacement resistance of the filler 6, thereby effectively preventing the filler 6 from loosening or falling off in the through hole, ensuring that the busbar 2 and the outer casing 1 always maintain reliable insulation, and reducing the risk of maintenance personnel coming into contact with live metal.

[0056] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5In one embodiment of the present invention, the power supply device 1000 for the server cabinet further includes two insulating pads 8. The two insulating pads 8 are respectively disposed on the side facing the busbar 2 on opposite side walls of the housing 1, and are located at the end of the housing 1 away from the bottom wall of the housing 1 in the third direction.

[0057] Among them, the insulating pad 8 refers to the sheet-like insulator covering the inner side wall of the outer casing 1. It can be made of rubber or polycarbonate material and is fixed to the side wall of the outer casing 1 by adhesive or snap-fit ​​to prevent direct contact between maintenance personnel and the busbar 2.

[0058] Specifically, two insulating pads 8 are fixed to the inner surfaces of the left and right side walls of the housing 1, respectively, covering the gap between the side walls and the busbar 2. Since the insulating pads 8 are located in the top area of ​​the housing 1, when maintenance personnel perform plugging and unplugging operations or maintenance, the top part of the side wall of the housing 1 that may be touched by their hands is completely covered by the insulating pads 8, thereby avoiding accidental contact with the live busbar 2 or metal parts.

[0059] By installing an insulating pad 8 on the top of the side wall of the housing 1, the exposed live metal parts are directly covered, forming a physical isolation barrier. This effectively blocks the contact path between maintenance personnel and live parts, reducing the risk of electric shock due to accidental contact during operation. In particular, for the high-frequency contact area on the top of the side wall of the housing 1, the safety protection capability of the power supply device is significantly improved.

[0060] Please refer to Figure 2 , Figure 3 as well as Figure 6 In one embodiment of this utility model, the power supply device 1000 for the server cabinet includes six baffles 5, and every two baffles 5 are assembled and connected to the front and rear ends of each busbar 2 and the corresponding insulating member 4 along the first direction.

[0061] The baffle 5 refers to a plate-like structure used to restrict the movement of the insulating component 4 along the first direction. It can be made of high-strength plastic and is fixed between the busbar 2 and the insulating component 4 by mechanical connection, thereby forming a limiting effect. The assembly connection refers to the fixing between components by detachable fasteners, which can be implemented by screws 9 or snap-fit ​​structures, making it easy to disassemble or adjust the baffle 5 during installation and maintenance.

[0062] Specifically, the six baffles 5 are divided into three groups, each group corresponding to one busbar 2. Each busbar 2 has two baffles 5 at each of its front and rear ends along its length. The baffles 5 are connected to both the busbar 2 and the insulating member 4 fitted onto the end of the busbar 2. For example, a screw 9 passes through a hole 5a on the baffle 5 and engages with a threaded hole 1a on both the busbar 2 and the insulating member 4, fixing the baffle 5 in a predetermined position. Thus, the forward and backward movement of the insulating member 4 along its length is simultaneously restricted by the baffles 5 on both sides, preventing the insulating member 4 from shifting due to vibration or external force.

[0063] By setting a double baffle 5 structure at both ends of each busbar 2, a symmetrical constraint is formed, which significantly improves the positioning stability of the insulating component 4, effectively prevents the insulating component 4 from sliding along the length direction during the operation or maintenance of the server cabinet, reduces the exposed area of ​​the live metal parts caused by the offset of the insulating component 4, thereby reducing the risk of maintenance personnel accidentally touching live parts and improving the safety protection capability of the power supply device.

[0064] Please refer to Figure 2 , Figure 3 as well as Figure 6 In one embodiment of this utility model, each baffle 5 has two through holes 5a, and the power supply device 1000 for the server cabinet also includes twelve screws 9; each pair of screws 9 passes through the two through holes 5a on a baffle 5 and is screwed to a busbar 2 and a corresponding insulating member 4.

[0065] The perforation 5a refers to the through-hole structure provided on the baffle 5, which can be circular or elliptical, used to accommodate the screw 9 and form a fixed connection with the busbar 2. The screw 9 is a threaded fastener, which can be made of stainless steel, and locks the baffle 5 to the busbar 2 and the insulating component 4 through thread engagement.

[0066] Specifically, the baffle 5 is engaged with the screw 9 through two through holes 5a, so that each baffle 5 forms a double fixation at both ends of the busbar 2 along the first direction. After passing through the baffle 5, the screw 9 is threadedly connected to the busbar 2 and the insulating component 4, so that a rigid constraint is formed between the baffle 5 and the busbar 2.

[0067] The symmetrical locking design with double screws 9 significantly improves the connection stability between the baffle 5 and the busbar 2. At the same time, the engagement of screws 9 with threaded holes 1a facilitates disassembly and maintenance without damaging the structure of the insulating component 4. This effectively prevents the insulating component 4 from shifting due to vibration or plugging / unplugging operations during server cabinet operation, ensuring that the live metal parts are always covered by insulating material and reducing the risk of maintenance personnel accidentally touching live parts.

[0068] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5In one embodiment of the present invention, the opposite two side walls of the outer shell 1 are bent outward at one end along the first direction to form a mounting portion 11, and the mounting portion 11 is configured to be assembled with the server cabinet.

[0069] The mounting section 11 refers to a structure formed by bending the end of the side wall of the outer casing 1 outwards. This can be achieved using stamping or bending processes and is used for mounting on the server rack. Its function is to enhance structural strength through a one-piece molding method while simplifying the installation process.

[0070] Specifically, the two side walls of the outer casing 1 are bent outward at their ends in the first direction to form mounting portions 11. This structure is directly connected to the server cabinet via screws 9 or clips. The bending angle of the mounting portions 11 can be designed as a right angle or a specific tilt angle according to the cabinet structure. The bent portion forms a continuous structure with the main body of the outer casing 1 to withstand the installation load. During installation, after the mounting portions 11 are aligned with the preset fixing points on the cabinet, they are fixed by tightening screws 9 or by inserting clips, thereby avoiding the disassembly difficulties caused by traditional welding or riveting processes.

[0071] The mounting part 11 is formed by directly bending the side wall of the outer shell 1, which eliminates the need for additional parts and ensures the flatness consistency between the mounting surface and the outer shell 1, effectively reducing assembly errors. This enables the power supply device to be installed quickly and accurately into the server cabinet, reducing manual adjustment steps. The integrated structure of the mounting part 11 and the outer shell 1 can avoid loosening of the connection due to vibration. At the same time, the continuous structure formed by bending can effectively disperse mechanical stress and improve long-term reliability.

[0072] Please refer to Figure 1 and Figure 4 In one embodiment of the present invention, the power supply device 1000 for the server cabinet further includes a fixing plate 10. The fixing plate 10 includes a protruding section 101 and two mounting sections 102 connected to each other. The two mounting sections 102 are located on both sides of the protruding section 101. The two mounting sections 102 are respectively assembled and connected to one end of the opposite side wall of the housing 1 away from the mounting part 11. The protruding section 101 is configured to stop the three busbars 2 from moving in the first direction.

[0073] The fixing plate 10 refers to a plate-like structure made of metal or insulating material that connects to the outer casing 1 via the mounting section 102. Specifically, it can be formed by stamping and bending processes to create an integral structure of the protruding section 101 and the mounting section 102, used to limit the axial displacement of the busbar 2. The protruding section 101 refers to the protruding part extending from the middle of the fixing plate 10 towards the busbar 2. Specifically, it can be an arc-shaped or angled structure, and its height can be set to cover the end of the busbar 2, preventing the busbar 2 from sliding through physical contact. The mounting section 102 refers to the flat parts on both sides of the fixing plate 10 that connect to the outer casing 1. Specifically, it can be fixed to the pre-drilled holes on the side wall of the outer casing 1 using bolts or clips, enabling quick assembly and disassembly.

[0074] Specifically, the two mounting sections 102 of the fixing plate 10 are fixed to the front end positions of the two side walls of the housing 1 by bolts, forming a symmetrical distribution with the mounting portion 11 at the rear end of the housing 1. The protruding section 101 covers the upper part of the three busbars 2. When the busbars 2 tend to displace along their length due to vibration or external force, the protruding section 101 contacts the end face of the busbars 2 to form mechanical interference, preventing further movement. The connection point between the mounting section 102 and the housing 1 is located at the end away from the mounting portion 11, so that the support span of the fixing plate 10 covers the entire front end area of ​​the busbar 2 group.

[0075] An independent fixing piece 10 is added to the front end of the outer casing 1 to form a double limit on the end of the busbar 2 with the server cabinet, avoiding the risk of overall displacement caused by single-point fixing failure, effectively preventing the busbar 2 from axial movement during operation or equipment vibration, and eliminating the risk of accidental contact between the live conductor and the outer casing 1 due to displacement.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
