Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to a server. Background Technology

[0002] In server power supply systems, the backplane is often located far from the power module due to layout requirements. Traditional solutions use fixed conductive copper strips directly connected to the chassis or power module with screws, forming a single-level fixed structure. Maintenance requires disassembling the chassis side panels, motherboard, memory, and other peripheral components layer by layer, sometimes even requiring tools to remove the screws, which is cumbersome and prone to damaging components. Because the conductive copper strips are directly fixed to the chassis, maintenance cannot be limited to a single component and often requires adjusting other modules, resulting in low maintenance efficiency and a high risk of misoperation. Furthermore, repairing the conductive copper strips requires whole-machine disassembly, which not only prolongs downtime but may also cause potential problems such as loose interfaces due to frequent disassembly and reassembly. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a server that solves the technical problem of low maintenance efficiency in the scenario of long-distance power supply of existing servers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A server includes a chassis body and a backplane disposed within the chassis body, characterized in that it further includes a power adapter module disposed within the chassis body, the power adapter module including a sub-chassis, a power backplane, an adapter board module, and a conductive copper strip; the power backplane is installed in the sub-chassis, the adapter board module is detachably connected to the sub-chassis; the conductive copper strip is detachably connected to the adapter board module, and one end of the conductive copper strip is electrically connected to the power backplane, and the other end is electrically connected to the backplane.

[0006] In one embodiment, the adapter board module is embedded in the sub-chassis and slidably connected to the sub-chassis.

[0007] In one embodiment, the adapter board module includes an adapter board, a tray, a PCIe card holder, and a copper strip holder. The adapter board, the tray, the PCIe card holder, and the copper strip holder are connected sequentially from top to bottom. The copper strip holder has a mounting groove adapted to the conductive copper strip, and the copper strip is embedded in the mounting groove.

[0008] In one embodiment, the conductive copper strip includes a first insertion portion, a copper strip body, and a second insertion portion. The first insertion portion is formed by the copper strip body extending from one end near the power backplate to the outside of the tray, for insertion into the power backplate interface. The second insertion portion is formed by the copper strip body extending outward through the mounting groove from one end near the middle backplate, for docking with the power interface of the middle backplate.

[0009] In one embodiment, the copper strip body is provided with a bent portion, and the mounting groove is provided with a guide slope corresponding to the position of the bent portion. The guide slope forms a guide angle with the insertion and extraction directions of the first insertion portion and the second insertion portion, and the extension directions of the first insertion portion, the copper strip body and the second insertion portion are parallel.

[0010] In one embodiment, the PCIe card tray covers the mounting slot and is fixed to the bottom of the tray, with a heat dissipation gap formed between the PCIe card tray and the mounting slot.

[0011] In one embodiment, the conductive copper strip is fixed to the copper strip seat by a copper strip screw, and the axis of the copper strip screw is perpendicular to the length direction of the conductive copper strip.

[0012] In one embodiment, there are two conductive copper strips, which are arranged in parallel on the adapter board module.

[0013] In one embodiment, the power adapter module further includes a power supply and several connectors. The power supply is electrically connected to the power supply backplane via the connectors, the conductive copper strip is electrically connected to the power supply backplane via the connectors, and the conductive copper strip is electrically connected to the middle backplane via the connectors.

[0014] In one embodiment, the power adapter module is embedded within the chassis body, and the sub-chassis is connected to the chassis body.

[0015] The advantages of this invention compared to existing technologies are as follows: Through the hierarchical and detachable design of the power adapter module, flexible maintenance of the power supply structure is achieved. Specifically, the adapter board module is detachably connected to the sub-chassis, and the conductive copper strip is also detachably connected to the adapter board module, forming a two-level detachable architecture. When maintenance of the conductive copper strip is required, the adapter board module can be completely disassembled from the sub-chassis first, and then the conductive copper strip can be individually disassembled and reassembled, avoiding the maintenance complexity caused by the direct fixing of the conductive copper strip to the chassis body in traditional solutions. This design, through modular separation, limits the maintenance scope of the conductive copper strip to the adapter board module level, reducing interference with other components within the chassis body and improving the convenience of maintenance operations. Simultaneously, the detachable connection method supports rapid replacement or repair of the conductive copper strip, shortening server downtime for maintenance, enhancing the maintainability of the power supply system, and effectively solving the technical problem of low maintenance efficiency of conductive copper strips in long-distance power supply scenarios.

[0016] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of the present invention more obvious and understandable, preferred embodiments are described in detail below.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] See Figures 1 to 10As shown in the figure, an embodiment of the present invention discloses a server, including a chassis body 1 and a backplane 2 disposed within the chassis body 1, and a power adapter module 3 disposed within the chassis body 1. The power adapter module 3 includes a sub-chassis 31, a power backplane 32, an adapter board module 33, and a conductive copper strip 34. The power backplane 32 is installed in the sub-chassis 31, and the adapter board module 33 is detachably connected to the sub-chassis 31. The conductive copper strip 34 is detachably connected to the adapter board module 33, and one end of the conductive copper strip 34 is electrically connected to the power backplane 32, and the other end is electrically connected to the backplane 2.

[0035] Specifically, a hierarchical, detachable power supply architecture is formed by installing a power transfer module 3, which includes a sub-chassis 31, a power backplane 32, an adapter board module 33, and conductive copper strips 34, inside the main chassis 1. The power backplane 32, as the core of power transfer, is fixed to the sub-chassis 31. The adapter board module 33 and the conductive copper strips 34 are detachably connected to form an independent unit. The two ends of the conductive copper strips 34 are electrically connected to the power backplane 32 and the middle backplane 2, respectively, thus constructing a complete long-distance power transmission path.

[0036] During operation, power from the power supply 35 is input to the adapter board module 33 via the power supply backplane 32 and transmitted to the middle backplane 2 via the conductive copper strip 34 to power the various modules of the server. During maintenance, the connection between the adapter board module 33 and the sub-chassis 31 is first disconnected, and then the conductive copper strip 34 is separated from the adapter board module 33, enabling layered maintenance. This layered, detachable design limits the maintenance scope of the conductive copper strip 34 to the module level, avoiding the complete machine disassembly issues caused by the direct fixing of the conductive copper strip 34 to the chassis body 1 in traditional solutions. This reduces interference with peripheral components such as the motherboard and memory, improving maintenance convenience and system maintainability.

[0037] In one embodiment, the adapter module 33 is embedded in the sub-chassis 31 and slidably connected to the sub-chassis 31.

[0038] Specifically, the adapter board module 33 is embedded in the sub-chassis 31 via a sliding connection. During operation, the adapter board module 33 is placed into the sub-chassis 31 and then pushed into the sub-chassis 31 to the limit position. For disassembly, the module can be pulled out entirely by applying force in the opposite direction, without the need for tools. This enables rapid installation and disassembly of the adapter board module 33, significantly improving maintenance efficiency. The guide structure reduces manual alignment errors and lowers the risk of interface damage due to improper operation.

[0039] Furthermore, in other embodiments, a connecting groove can be provided on the inner wall of the sub-chassis 31, and a connecting guide rail corresponding to the connecting groove can be provided on the side of the adapter module 33. The connecting guide rail and the connecting groove form a guiding structure to realize the precise positioning and linear insertion and removal of the module, avoiding the tedious operation of picking up fasteners one by one for traditional screw fixing.

[0040] In one embodiment, the adapter board module 33 includes an adapter board 331, a tray 332, a PCIe card holder 333, and a copper strip holder 334. The adapter board 331, the tray 332, the PCIe card holder 333, and the copper strip holder 334 are connected sequentially from top to bottom. The copper strip holder 334 has a mounting groove 3341 adapted to the conductive copper strip 34, and the conductive copper strip 34 is embedded in the mounting groove 3341.

[0041] Specifically, the adapter board module 33 adopts a stacked modular architecture of "adapter board 331-tray 332-PCIE card holder 333-copper strip holder 334". The conductive copper strip 34 is embedded in the mounting groove 3341 of the copper strip holder 334 and achieves stable support through physical limiting. It can be understood that in this embodiment, the components of each layer are fixed layer by layer by screws or buckles to form an integrated component.

[0042] During operation, the conductive copper strip 34 is first inserted into the mounting slot 3341 of the copper strip seat 334 and tightened. Then, the PCIE card bracket 333, tray 332 and adapter plate 331 are stacked in sequence and connected as a whole by fasteners. During maintenance, it can be disassembled layer by layer to replace the conductive copper strip 34 or other components individually.

[0043] The stacked structure integrates the conductive copper strip 34 with components such as the PCIe card tray 333 and the adapter board 331 into the same module, so that the maintenance of the conductive copper strip 34 does not require the involvement of other internal structures of the sub-chassis 31; the limiting design of the mounting slot 3341 can prevent the conductive copper strip 34 from being displaced due to vibration, ensuring power supply stability, while the modular design facilitates standardized production and replacement.

[0044] In other embodiments, the copper strip holder 334 and the tray 332 can be formed by an integrated stamping process to reduce assembly steps; an elastic pad can be provided in the mounting groove 3341 to provide shock absorption while fixing the conductive copper strip 34 and adapt to high vibration environment.

[0045] In one embodiment, the conductive copper strip 34 includes a first insertion portion 341, a copper strip body 342, and a second insertion portion 343. The first insertion portion 341 is formed by extending one end of the copper strip body 342 near the power backplate 32 to the outside of the tray 332, and is used to insert into the interface of the power backplate 32. The second insertion portion 343 is formed by extending one end of the copper strip body 342 near the middle backplate 2 through the mounting groove 3341 and outward, and is used to dock with the power interface of the middle backplate 2.

[0046] Specifically, the conductive copper strip 34 is divided into a first plug-in part 341, a copper strip body 342, and a second plug-in part 343. The copper strip body 342 is embedded in the mounting groove 3341. The first plug-in part 341 extends to the outside of the tray 332 for inserting into the power backplate 32 interface. The second plug-in part 343 passes through the mounting groove 3341 and extends outward for connecting to the backplate 2 interface, forming a direct connection structure with "exposed ends and embedded in the middle", eliminating the need for cable conversion.

[0047] During operation, when installing the adapter board module 33, the first connector 341 is plugged into the interface of the power backplane 32, and the second connector 343 is plugged into the interface of the middle backplane 2, forming a direct conductive path of "power backplane 32 - conductive copper strip 34 - middle backplane 2". During disassembly, the first connector 341 and the second connector 343 at both ends are simultaneously pulled out, achieving rapid separation of the conductive copper strip 34 from the interfaces at both ends. The design of the first connector 341 and the second connector 343 avoids the cumbersome wiring and high loss problems of traditional cable connections, improving power supply efficiency. The modular plug-in / plug-out operation significantly shortens the replacement time of the conductive copper strip 34, improving maintenance efficiency.

[0048] It is understood that in other embodiments, the plug-in portion may preferably adopt a foolproof design, setting the first plug-in portion 341 and the second plug-in portion 343 as an asymmetrical interface shape to avoid damage caused by reverse insertion.

[0049] In one embodiment, the copper strip body 342 is provided with a bending portion 3421, and the mounting groove 3341 is provided with a guide slope 3342 corresponding to the bending portion 3421. The guide slope 3342 forms a guide angle with the insertion and removal directions of the first insertion portion 341 and the second insertion portion 343. The extension directions of the first insertion portion 341, the copper strip body 342 and the second insertion portion 343 are parallel.

[0050] Specifically, the copper strip body 342 is provided with a bent portion 3421, which cooperates with the guide slope 3342 in the mounting groove 3341 to form an insertion and removal guide structure. The angle of the bent portion 3421 matches the inclination angle of the guide slope 3342, ensuring that the extension directions of the first insertion portion 341, the copper strip body 342, and the second insertion portion 343 are parallel, guiding the conductive copper strip 34 to be accurately inserted and removed along a preset path. It can be understood that the first insertion portion 341, the copper strip body 342, and the second insertion portion 343 are generally Z-shaped.

[0051] During operation, when the conductive copper strip 34 is inserted, the bent portion 3421 conforms to the guide slope 3342. The geometry of the guide slope 3342 forces the conductive copper strip 34 to move horizontally until the first insertion portion 341 is fully embedded in the power interface. When pulled out, the guide slope 3342 provides support, reducing insertion and extraction resistance caused by lateral movement when the conductive copper strip 34 leaves the interface. The cooperation between the guide slope 3342 and the bent portion 3421 ensures the insertion and extraction accuracy of the conductive copper strip 34, avoiding misalignment or poor contact of the interface pins; it also reduces insertion and extraction force, alleviates operator fatigue, and ensures the parallelism of the conductive copper strip 34, improving the stability of the electrical connection.

[0052] In one embodiment, the PCIe card tray 333 covers the mounting slot 3341 and is fixed to the bottom of the tray 332, and a heat dissipation gap is formed between the PCIe card tray 333 and the mounting slot 3341.

[0053] Specifically, the PCIe card tray 333 covers the mounting slot 3341 of the copper strip holder 334 and is fixed to the bottom of the tray 332, forming a physical shield for the conductive copper strip 34. The shielding structure improves the physical safety of the conductive copper strip 34 and reduces the risk of short circuit. A heat dissipation gap is reserved between the PCIe card tray 333 and the conductive copper strip 34, allowing airflow to dissipate the heat generated by the conductive copper strip 34, thereby reducing the operating temperature of the conductive copper strip 34, extending its service life and avoiding the decrease in power supply stability due to overheating, while providing installation support for the PCIe card.

[0054] During operation, the PCIe card tray 333 is fixed to the bottom of the tray 332 with screws, completely covering the conductive copper strip 34 in the mounting slot 3341 to prevent foreign objects from entering or accidental contact by personnel; the heat dissipation gap allows the surface heat of the conductive copper strip 34 to be transferred to the tray through natural convection or radiation, and then discharged through the sub-chassis 31.

[0055] In one embodiment, the conductive copper strip 34 is fixed to the copper strip seat 334 by a copper strip screw 4, and the axis of the copper strip screw 4 is perpendicular to the length direction of the conductive copper strip 34.

[0056] Specifically, the conductive copper strip 34 is fixed to the copper strip seat 334 by copper strip screws 4. The axis of the copper strip screws 4 is perpendicular to the length direction of the conductive copper strip 34, forming a lateral locking structure. This lateral fixing method ensures that the conductive copper strip 34 maintains a stable connection under vibration. The friction between the head of the copper strip screws 4 and the surface of the conductive copper strip 34 prevents the conductive copper strip 34 from sliding or loosening along its length. At the same time, no special tools are required for screw installation and removal, making it suitable for quick on-site maintenance. The fixing reliability is superior to that of traditional snap-fit ​​structures.

[0057] Furthermore, during assembly, after the conductive copper strip 34 is embedded into the mounting groove 3341, a screwdriver is used to screw the copper strip screw 4 through the through hole on the conductive copper strip 34 into the threaded hole of the copper strip seat 334 to achieve fixation; during disassembly, the conductive copper strip 34 can be separated by unscrewing the copper strip screw 4 in the opposite direction, which is simple and convenient to operate.

[0058] In one embodiment, there are two conductive copper strips 34, which are arranged in parallel on the adapter module 33.

[0059] Specifically, two conductive copper strips 34 are arranged in parallel on the adapter board module 33, respectively for transmitting power signals of different phases or realizing redundant power supply, and avoiding electromagnetic interference through spatial isolation. At the same time, the parallel dual conductive copper strips 34 design improves the current carrying capacity of the power supply system to meet the needs of high-power servers; the redundant structure reduces the system failure rate, extends the mean time between failures, and significantly improves reliability.

[0060] During operation, the two conductive copper strips 34 are simultaneously inserted into the corresponding interfaces of the power backplane 32 and the middle backplane 2 to form a dual power supply channel. When one conductive copper strip 34 fails, the other can independently undertake the power supply task to ensure the continuous operation of the server.

[0061] In one embodiment, the power adapter module 3 further includes a power supply 35 and a plurality of connectors 36. The power supply 35 is electrically connected to the power backplate 32 through the connectors 36, the conductive copper strip 34 is electrically connected to the power backplate 32 through the connectors 36, and the conductive copper strip 34 is electrically connected to the middle backplate 2 through the connectors 36.

[0062] Specifically, the power adapter module 3 integrates a power supply 35 and a connector 36. The power supply 35 is electrically connected to the power backplane 32 through the terminals of the connector 36. The conductive copper strip 34 then transfers the power signal through the connector 36, forming a standardized power supply link of "power supply 35-connector 36-power backplane 32-conductive copper strip 34-middle backplane 2".

[0063] During operation, the power output from power supply 35 is transmitted to power supply backplane 32 via connector 36. After being distributed by the internal circuitry of power supply backplane 32, the power is then transmitted to conductive copper strip 34 via another set of connector 36 terminals, and finally delivered to the middle backplane 2. Components can be quickly connected or disconnected via connector 36 plugging and unplugging, eliminating the need for soldering. Simultaneously, the standardized connector 36 supports hot-swapping, allowing for the replacement of modules or power supply 35 without interrupting the overall power supply 35, improving maintenance efficiency. The precision design of connector 36 terminals reduces contact resistance and minimizes energy loss.

[0064] In one embodiment, the power adapter module 3 is embedded in the chassis body 1, and the sub-chassis 31 is connected to the chassis body 1.

[0065] Specifically, the power adapter module 3 is embedded entirely within the main chassis 1, and the sub-chassis 31 is fixed to the main chassis 1 with screws or clips, forming a compact, integrated structure. This reduces the risk of electromagnetic interference while minimizing internal space occupation and increasing mechanical strength. Simultaneously, the module-level maintenance mode shortens fault location and repair time, significantly improving operational efficiency and enhancing system shock resistance. During installation, the sub-chassis 31 is aligned with the insertion slot in the main chassis 1, pushed in, and locked with fasteners. For disassembly, the fasteners are loosened to remove the module entirely, facilitating comprehensive inspection or replacement of internal components.

[0066] In summary, the complete installation process of a server in this embodiment is as follows:

[0067] First, the power supply backplate 32 is fixedly installed inside the sub-chassis 31, forming the basic frame of the power adapter module 3. Next, the adapter board module 33 is embedded into the sub-chassis 31 via a sliding connection and fixed. Then, the conductive copper strip 34 is embedded into the copper strip seat 334 mounting groove 3341 of the adapter board module 33, ensuring that the bent portion 3421 of the copper strip body 342 is in full contact with the guide slope 3342 of the mounting groove 3341. The guide structure guides the conductive copper strip 34 along a preset path, ensuring that the extension directions of the first insertion part 341, the copper strip body 342, and the second insertion part 343 are parallel. Finally, a copper strip screw 4 is passed laterally through the through hole of the conductive copper strip 34 and screwed into the copper strip seat 33. 4. Secure the conductive copper strip 34 to the copper strip base 334 using threaded holes; then cover the PCIE card tray 333 with the mounting slot 3341 and fix it to the bottom of the tray 332 to form a heat dissipation gap; after completing the assembly of the adapter board module 33, push it into the sub-chassis 31 as a whole. At this time, the first plug part 341 of the conductive copper strip 34 automatically inserts into the power backplane 32 interface, and the second plug part 343 simultaneously passes through the mounting slot 3341 and connects with the power interface of the middle backplane 2 to achieve electrical connection; finally, embed the assembled power adapter module 3 into the chassis body 1, and fix the sub-chassis 31 to the chassis body 1 with screws or clips to complete the installation of the entire server power adapter module 3.
