Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a bus device for servers. Background Technology

[0002] As data centers continue to expand in scale, the power density of server racks is constantly increasing, requiring multiple high-current buses to be installed inside the racks for efficient power distribution. A common practice is to fix three parallel buses in an insulating base to form an integrated bus module, then fit this module into a U-shaped metal casing, and finally secure it to the rack pillars through through-holes on both sides of the casing, completing the installation within the rack.

[0003] Existing insulating bases mostly adopt a flat plate structure, and the creepage distance between adjacent busbars is limited by the base thickness and surface path length. In high humidity and high dust environments, conductive contaminants easily accumulate on the surface of the insulating base, leading to an increased risk of discharge along the surface and reduced stability of the bus module during long-term operation.

[0015] In one embodiment, the server bus device further includes a housing, the housing including a bottom plate and two side plates connected together, the bottom plate and the two side plates forming a receiving groove, and the bus module located in the receiving groove; wherein, a gap is formed between the three busbars and the housing.

[0016] In one embodiment, the ends of both side plates away from the base plate are bent to form a bent section, and the two bent sections are configured to be mounted on a second mounting plane.

[0017] In one embodiment, the server bus device further includes a baffle, to which the two bent sections are assembled; the baffle is configured to cover the opening of the receiving groove; and the side of the baffle facing away from the housing is configured to be mounted on a second mounting plane.

[0021] In one embodiment, the base plate and both side plates are formed with a plurality of air vents in a rectangular array.

[0022] In the technical solution of this utility model, the server bus device includes a bus module and an insulating base. The bus module includes three busbars. The insulating base includes a base plate and three fixed wall groups protruding from the base plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] In existing busbar devices, the creepage distance between adjacent busbars is limited by the thickness of the insulating base and the surface path length. In high humidity and high dust environments, conductive contaminants easily accumulate on the surface of the insulating base, leading to a significant increase in the risk of surface discharge and reduced long-term operational stability of the busbars. This problem stems from the lack of an effective isolation mechanism for surface contaminant accumulation in the insulating base structure, and the fact that the fixed wall assembly layout does not form a physical isolation barrier, failing to block the migration path of contaminants between adjacent conductors.

[0039] To address the aforementioned problems, this utility model proposes a server bus converter 1000. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 A schematic diagram of the structure of an embodiment of the server bus device 1000 provided by this utility model.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model proposes a busbar device 1000 for servers, including a busbar module 1 and an insulating base 2. The busbar module 1 includes three busbars 11. The insulating base 2 includes a substrate 21 and three fixed wall groups 22 protruding from the substrate 21. Each fixed wall group 22 includes two fixed walls 221. The two fixed walls 221 in each fixed wall group 22 and the substrate 21 enclose a mounting groove 22a. Each busbar 11 is inserted into a mounting groove 22a. A creepage groove 2a is formed between two adjacent fixed wall groups 22 to increase the creepage distance of each busbar 11.

[0041] Busbar 11 refers to a metal conductor strip used for conducting current, which can be made of copper or aluminum, and is used to transmit large currents in the server power distribution system. Fixed wall assembly 22 refers to an assembly consisting of two upright wall panels, which can be made of injection-molded insulating material, and is used to clamp and fix busbar 11. Mounting groove 22a refers to a groove-shaped space formed by the two fixed walls 221 and the base plate 21, which can be achieved by adjusting the spacing of the fixed walls 221, and is used to accommodate and position busbar 11. Creepage groove 2a refers to a recessed area formed between adjacent fixed wall assemblies 22, which can be achieved by increasing the lateral spacing between the fixed wall assemblies 22, and is used to extend the current leakage path along the surface of the insulating base 2, preventing short circuits caused by contaminants.

[0042] In the technical solution of this utility model, the current combining device includes a current combining module 1 and an insulating base 2; the current combining module 1 is composed of three busbars 11 for current collection and distribution; the insulating base 2 is composed of a base plate 21 and three fixed wall groups 22, the fixed wall groups 22 protruding from the surface of the base plate 21; each fixed wall group 22 includes two fixed walls 221, which together with the base plate 21 form a mounting groove 22a; the three busbars 11 are respectively inserted into the three mounting grooves 22a to achieve mechanical fixation and electrical isolation; a creepage groove 2a structure is formed between two adjacent fixed wall groups 22. The creepage groove 2a increases the surface creepage distance between busbars 11, improving electrical insulation performance. The presence of the creepage groove 2a interrupts the continuous migration path of contaminants between adjacent busbars 11, preventing the accumulation and bridging of conductive particles. By optimizing the structure of the insulating base 2, the creepage distance is effectively extended without increasing the overall volume, improving electrical insulation performance and anti-pollution capability. This maintains the stability of the original installation structure and forms an effective contaminant accumulation blocking mechanism, thereby improving the long-term operational reliability of the busbar device in harsh environments.

[0043] Please refer to Figure 4 In one embodiment of the present invention, the outer fixed wall 221 of the two fixed wall groups 22 located on both sides is provided with a first threaded hole 221a, and any fixed wall 221 of the middle fixed wall group 22 is provided with a second threaded hole 221b, so that the three fixed wall groups 22 are respectively screwed to the corresponding busbar 11.

[0044] The first threaded hole 221a is distributed on the outer fixing wall 221 of the two side fixing wall assemblies 22, and the second threaded hole 221b is provided on any fixing wall 221 of the middle fixing wall assembly 22. The middle fixing wall assembly 22 exposes the second threaded hole 221b to the outer area of ​​the two side fixing wall assemblies 22 through a protruding structure 2211. Each of the three fixing wall assemblies 22 forms an independent threaded hole structure, corresponding to the installation positions of the three busbars 11 respectively. During the screwing process, the screw structure passes through the through hole of the busbar 11 and forms a locking force with the corresponding threaded hole.

[0045] In the two fixed wall groups 22 located on both sides, the outer fixed wall 221 is provided with a first threaded hole 221a, and any fixed wall 221 in the middle fixed wall group 22 is provided with a second threaded hole 221b. The first threaded hole 221a and the second threaded hole 221b are respectively screwed to the corresponding busbar 11. Through the above technical solution, this application achieves a reliable connection between the busbar 11 and the fixed wall group 22. As a result, the installation stability of the busbar 11 is improved, reducing the risk of the busbar 11 loosening or falling off during use. Furthermore, the screw connection method facilitates the disassembly and replacement of the busbar 11, improving the convenience of maintenance and repair. In addition, by providing threaded holes in different positions, the three busbars 11 can be independently fixed to their respective fixed wall groups 22, enhancing the stability and reliability of the overall structure.

[0046] During the screwing process, the threaded holes of the middle fixed wall assembly 22 are blocked by the fixed wall assemblies 22 on both sides, which makes the installation of the middle busbar 11 difficult and affects the stability of the overall structure.

[0047] To solve this problem, please refer to... Figure 4 In one embodiment of the present invention, the middle fixed wall assembly 22 has a protruding structure 2211, which protrudes from the two fixed wall assemblies 22 on both sides; the second threaded hole 221b is formed in the protruding structure 2211 so that the second threaded hole 221b is exposed on the two fixed wall assemblies 22 on both sides.

[0048] The outer contour of the protruding structure 2211 extends beyond the edge plane of the two fixed wall assemblies 22. The second threaded hole 221b is provided through the axial direction of the protruding structure 2211, and the hole axis is perpendicular to the substrate 21.

[0049] Specifically, when the protruding structure 2211 of the intermediate fixed wall assembly 22 extends outward, the second threaded hole 221b penetrates the protruding structure 2211 vertically, allowing the screwdriver tip to directly contact the second threaded hole 221b from the outside of the two fixed wall assemblies 22. At the same time, the second threaded hole 221b is opened in the protruding structure 2211, so that the first threaded hole 221a and the second threaded hole 221b are misaligned, which can prevent the three busbars 11 from shaking relative to the insulating seat 2, thereby making the connection between the insulating seat 2 and the three busbars 11 more stable.

[0050] As a preferred embodiment, the solution of this application is specifically implemented as follows: The middle fixed wall assembly 22 has a protruding structure 2211, which protrudes from the two fixed wall assemblies 22 on both sides. A second threaded hole 221b is formed in the protruding structure 2211, so that the second threaded hole 221b is exposed on both sides of the fixed wall assemblies 22. Specifically, the protruding structure 2211 of the middle fixed wall assembly 22 can be a rectangular boss, the height of which is higher than that of the two side fixed wall assemblies 22. The second threaded hole 221b can be formed on the side of the boss, so that the second threaded hole 221b is completely exposed outside the two side fixed wall assemblies 22. This design allows the middle busbar 11 to be firmly connected to the middle fixed wall assembly 22 through the second threaded hole 221b, without affecting the installation of the two side busbars 11. Through the above technical solution, this application achieves a reliable connection between the middle busbar 11 and the middle fixed wall assembly 22, while ensuring the independent installation of the three busbars 11. The protruding structure 2211 is designed to offset the first threaded hole 221a from the second threaded hole 221b, improving the overall structural stability. Furthermore, the exposed design of the second threaded hole 221b facilitates the installation and removal of screws by operators, enhancing the convenience of assembly and maintenance.

[0051] When the existing busbar module 1 is installed in the cabinet as a whole through the metal casing 5, there is no effective insulation between the casing 5 and the busbar 11, and the mounting plane of the casing 5 and the cabinet is the same, which makes it difficult to adapt to the fixing requirements of different installation scenarios.

[0052] To solve the above problems, please refer to... Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 This utility model also proposes a server busbar device 1000, which includes a busbar module 1, an insulating base 2, an insulating adapter 3, and a fixing plate 4. The busbar module 1 includes three busbars 11; the insulating base 2 includes a base plate 21 and three fixing wall groups 22 protruding from the base plate 21; each fixing wall group 22 includes two fixing walls 221, and the two fixing walls 221 in each fixing wall group 22 and the base plate 21 enclose a mounting groove 22a; each busbar 11 is inserted into a mounting groove 22a and assembled with the corresponding fixing wall group 22; the insulating adapter 3 is assembled with two busbars 11 located on both sides; the fixing plate 4 is disposed on the side of the insulating adapter 3 away from the busbar module 1, and the fixing plate 4 is configured to be mounted on a first mounting plane.

[0053] The fixed wall assembly 22 forms a mounting groove 22a through two fixed walls 221, allowing the busbar 11 to be inserted and fixed in a direction perpendicular to the base plate 21. The insulating adapter 3 is made of polycarbonate material and has snap-fit ​​structures at both ends, which form an interference fit with the grooves of the busbars 11 on both sides. The surface of the fixing plate 4 has two sets of mounting holes. One set of holes is clearance-fitted with the positioning post of the insulating adapter 3, and the other set of holes is configured to be connected to the side wall of the cabinet by bolts.

[0054] Specifically, after the busbar 11 is inserted into the mounting slot 22a of the insulating base 2, it is laterally limited by the fixed wall assembly 22. The insulating adapter 3 connects the two busbars 11 through a snap-fit ​​structure, forming a lateral support structure to prevent axial displacement of the busbar 11. The insulating adapter 3 forms an insulating isolation layer between the busbar 11 and the fixing plate 4, avoiding direct contact between metal parts that could lead to leakage. After the fixing plate 4 and the insulating adapter 3 are assembled, they can be directly installed on the first mounting plane, thereby avoiding the risk of direct leakage caused by installing the busbar module 1 on the housing 5.

[0055] Please refer to Figure 1 , Figure 5 , Figure 6 as well as Figure 7 In one embodiment of the present invention, the server bus device 1000 further includes a housing 5, which includes a bottom plate 51 and two side plates 52 connected to each other. The bottom plate 51 and the two side plates 52 enclose a receiving groove 5a, and the bus module 1 is located in the receiving groove 5a. A gap is formed between the three busbars 11 and the housing 5.

[0056] The bottom plate 51 and the two side plates 52 are formed into a U-shaped structure by stamping or bending processes, and the depth of the receiving groove 5a is greater than the thickness of the busbar 11.

[0057] By housing the busbar module 1 within the casing 5 and leaving a gap between the busbar 11 and the casing 5, the busbar 11 is effectively protected, preventing external debris from contacting it. Simultaneously, the metal casing 5 also shields against electromagnetic interference, improving the overall safety and reliability of the server busbar device 1000. Furthermore, the structural design of the casing 5 facilitates the installation and maintenance of the server busbar device 1000, enhancing its practicality.

[0058] Please refer to Figure 1 , Figure 5 as well as Figure 8 In one embodiment of the present invention, the ends of the two side plates 52 away from the bottom plate 51 are bent to form a bent section 521, and the two bent sections 521 are configured to be installed on the second mounting plane.

[0059] The installation section is formed by bending the end of the side plate 52 at a bending angle of 90 degrees, and the installation section is integrally formed with the side plate 52.

[0060] The tops of the two side panels 52 are bent outwards to form horizontal mounting sections. Multiple mounting holes are provided on the mounting sections for securing the server busbar 1000 to the second mounting plane. The width of the mounting sections can be designed according to actual needs to ensure sufficient mounting strength.

[0061] Through the above technical solution, this application achieves a stable installation of the server bus converter 1000. The mounting section provides additional fixing points, enhancing the overall stability of the server bus converter 1000. The design of the mounting section also facilitates installation and disassembly operations by maintenance personnel, improving installation efficiency and maintenance convenience.

[0062] Please refer to Figure 1 , Figure 5 as well as Figure 6 In one embodiment of the present invention, the server bus device 1000 further includes a baffle 6, and two bent sections 521 are assembled and connected to the baffle 6; the baffle 6 is configured to cover the opening of the receiving groove 5a; the side of the baffle 6 facing away from the outer shell 5 is configured to be installed on a second mounting plane.

[0063] The baffle 6 is detachably fixed to the mounting section via a mechanical connection, including but not limited to screw fastening or snap-fit ​​engagement. The baffle 6 covers the opening area of ​​the slot in the outer shell 5, and its edges extend to the outer sides of the two side plates 52. After the baffle 6 is connected to the mounting section, it forms a closed surface perpendicular to the base plate 51, completely covering the top of the receiving slot 5a.

[0064] Specifically, the baffle 6 is rigidly connected to the housing 5 through two mounting sections. While covering the slot, the baffle 6 transfers the mounting load of the housing 5 to its own plane, preventing the side plate 52 from directly bearing shear force. An insulating coating can be applied to the surface of the baffle 6 to prevent the formation of a conductive path between the busbar 11 and the cabinet.

[0065] As a preferred embodiment, the solution of this application is specifically implemented as follows: The server bus device 1000 includes a housing 5, a bus module 1, an insulating base 2, an insulating adapter 3, a fixing plate 4, and a baffle 6. The housing 5 includes a bottom plate 51 and two side plates 52 connected to each other, which together form a receiving groove 5a. The bus module 1 is located in the receiving groove 5a and includes three busbars 11. The insulating base 2 includes a base plate 21 and three fixing wall groups 22 protruding from the base plate 21. Each fixing wall group 22 includes two fixing walls 221, which together with the base plate 21 form a mounting groove 22a. Each busbar 11 is inserted into a mounting groove 22a and assembled with the corresponding fixing wall group 22. The insulating adapter 3 is assembled with the two busbars 11 located on both sides. A fixing plate 4 is located on the side of the insulating adapter 3 facing away from the busbar module 1, and is configured to be mounted on the first mounting plane. The ends of both side plates 52 away from the base plate 51 are bent to form mounting sections, and these two mounting sections are configured to be mounted on the second mounting plane. The two mounting sections are assembled and connected to the baffle 6. The baffle 6 is configured to cover the opening of the receiving groove 5a. The side of the baffle 6 facing away from the outer casing 5 is configured to be mounted on the second mounting plane.

[0066] By covering the opening of the receiving tank 5a with a baffle 6, external debris is effectively prevented from entering the receiving tank 5a, thus improving the safety of the manifold. The modular connection between the baffle 6 and the mounting section facilitates disassembly and maintenance.

[0067] Please refer to Figure 1 and Figure 6 In one embodiment of this utility model, the baffle 6 has multiple through holes 6a to expose part of the structure of the three busbars 11.

[0068] The perforation 6a can be set as an elongated strip, aligned with the length direction of the busbar 11, so that part of the surface of the busbar 11 is exposed to facilitate electrical connection with the conductive components of the server.

[0069] Please refer to Figure 1 , Figure 6 as well as Figure 8 In one embodiment of the present invention, the baffle 6 is provided with a plurality of first through holes 6b penetrating the two bent sections 521, so that a plurality of screw structures can pass through the baffle 6 and be screwed into the two bent sections 521 respectively; both bent sections 521 are provided with a plurality of second through holes 521a penetrating the baffle 6, so that a plurality of screw structures can pass through the two bent sections 521 and be screwed into the baffle 6 respectively.

[0070] The interlocking and fixing of the baffle 6 and the mounting section is achieved by a two-way screw connection structure, which can avoid the problem of connection loosening caused by assembly stress concentration or mechanical vibration due to unidirectional locking.

[0071] Please refer to Figure 7 and Figure 8 In one embodiment of this utility model, the bottom plate 51 and the two side plates 52 are each formed with a plurality of air vents 5b in a rectangular array.

[0072] Among them, the vent holes 5b are evenly distributed in a rectangular array on the surface of the bottom plate 51 and the two side plates 52, with the hole spacing being consistent and the hole shape being circular or square.

[0073] Specifically, during operation, the heat generated by the manifold 11 is transferred to the outside through the vents 5b. External air enters the receiving tank 5a through the vents 5b, creating convection and carrying away the accumulated heat. The rectangular array layout ensures uniform airflow distribution, preventing localized overheating. The vent diameter and spacing design ensures ventilation efficiency while preventing the entry of large particulate pollutants.

[0074] This application utilizes rectangular array-distributed vent holes 5b to achieve forced convection of air inside and outside the housing 5, effectively reducing the temperature rise in the contact area between the busbar 11 and the housing 5. At the same time, the uniformly distributed vent hole 5b structure avoids the concentrated accumulation of dust in local areas, reduces the probability of conductive contaminants adhering to the surface of the insulating base 2, thereby reducing the risk of discharge breakdown caused by surface contamination and improving the long-term operational reliability of the server busbar device 1000 in harsh environments.

[0075] 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.
