[0029] See Figures 1 to 4 In the specific embodiment shown, the present utility model discloses a structure for realizing the compatibility of an L-shaped main board with a 4U server, including: an L-shaped main board 10, an adapter board 20 and a power backplane 30. The adapter board 20 is electrically connected to the L-shaped main board 10, the power backplane 30 is electrically connected to the adapter board 20, and the power backplane 30 is provided with 1-4 CRPS power interfaces.
[0030] Specifically, by designing a combination of an L-shaped main board 10, an adapter board 20, and a power backplane 30, the traditional L-shaped main board 10 that was originally not applicable to 4U servers can be made compatible and integrated into this standard server architecture, greatly expanding the hardware compatibility and application scope of the server. It allows the use of the existing L-shaped main board 10 to be compatible with the 4U server system without replacing or modifying the main board design, saving the development cycle and cost without having to re-develop the main board. Additionally, re-designing and developing a main board that can be directly applied to 4U servers is not only costly but also time-consuming. By introducing the design of the adapter board 20 and the power backplane 30, this requirement is avoided, and the existing L-shaped main board 10 is directly utilized, thus significantly saving the development cost and shortening the product listing time cycle, which is particularly important for enterprises that need to quickly respond to market changes and improve product competitiveness. Moreover, the power backplane 30 is designed with 1-4 CRPS power interfaces. This design not only provides power redundancy function, enhancing the reliability and stability of the system, but also reserves space for future expansion and upgrade. For example, the power modules can be increased or decreased according to actual needs, or a higher-power power supply can be replaced to support a more powerful hardware configuration. Additionally, through the bridging function of the adapter board 20 and the power backplane 30, the L-shaped main board 10 can be smoothly connected to the power supply and signal transmission system of the 4U server, simplifying the internal connection lines and layout of the system, which is beneficial to improving the overall performance and heat dissipation efficiency of the system.
[0031] In one embodiment, the L-shaped main board 10 is provided with a CRPS power connector 11, and the adapter board 20 is provided with a gold finger end corresponding to the CRPS power connector 11.
[0032] Specifically, the CRPS power connector 11 is a key component on the L-shaped motherboard 10 for receiving external power input. It realizes electrical connection with the adapter board 20 through the gold finger end, ensuring that the L-shaped motherboard 10 can obtain a stable power supply. This design enables the power to be efficiently transmitted to the L-shaped motherboard 10, supporting the normal operation of the L-shaped motherboard 10 and the hardware devices thereon. In addition, the gold finger end, as an interface corresponding to the CRPS power connector 11 on the adapter board 20, has a high degree of conductivity and stability. Through the precise docking of the gold finger, the integrity and reliability of the power signal transmitted between the L-shaped motherboard 10 and the adapter board 20 can be ensured. In addition, the docking method of the gold finger end and the CRPS power connector 11 is adopted to realize the modular design between the L-shaped motherboard 10 and the adapter board 20. This design enables the L-shaped motherboard 10 and the adapter board 20 to be replaced, upgraded or repaired independently without the need for large-scale disassembly of the entire system, thereby improving the maintainability and scalability of the system. In addition, the docking method of the gold finger end and the CRPS power connector 11 provides a stable electrical connection basis for this expansion. In addition, the close connection between the gold finger end and the CRPS power connector 11 can reduce the interference and loss of the power signal during the transmission process, which helps to improve the overall stability and reliability of the system and reduce problems caused by electrical failures. Moreover, the gold finger end is usually made of high-quality metal materials and is specially treated to improve its wear resistance and corrosion resistance. This design enables the gold finger end to withstand multiple plugging and unplugging and long-term use, thereby extending the service life of the L-shaped motherboard 10 and the adapter board 20.
[0033] In one embodiment, the gold finger end is detachably plugged into the CRPS power connector 11 .
[0034] Specifically, the detachable plug-in design of the gold finger end and the CRPS power connector 11 makes the electrical connection very fast and convenient. The user or technician only needs to simply insert the gold finger end into the CRPS power connector 11 to achieve electrical connection without complicated welding or fixing process; similarly, when the electrical connection needs to be disconnected, just gently pull out the gold finger end without using special tools or performing complicated operations. This design greatly improves the maintainability and flexibility of the system. In addition, with the advancement of technology and the replacement of hardware, it may be necessary to upgrade the server. Through the detachable plug-in design of the gold finger end, the old L-shaped motherboard 10 or adapter board 20 can be easily replaced with a new model, so as to enjoy more advanced performance and functions.
[0035] In one embodiment, the adapter board 20 is provided with a female connector 21 , and the power backplane 30 is provided with a male connector 31 , and the male connector 31 is plugged into the female connector 21 to form a conducting state.
[0036] Specifically, the design of the female connector 21 and the male connector 31 enables a stable electrical connection to be formed between the adapter board 20 and the power backplane 30. When the male connector 31 is plugged into the female connector 21, the contact surface between the two forms a conductive path, allowing current and signals to be freely transmitted between the adapter board 20 and the power backplane 30. In addition, the plugged female connector 21 and the male connector 31 can fit tightly to form a low-resistance, high-reliability electrical connection. This conductive state is the basis for the normal operation of the electronic system, ensuring that power can be stably supplied to the adapter board 20 and the L-shaped motherboard 10. In addition, the adapter board 20 and the power backplane 30 are connected by plugging the female connector 21 and the male connector 31. This design embodies the modular concept, which allows adapter boards 20 and power backplanes 30 with different functions to be combined and matched through standardized interfaces to meet the needs of different application scenarios. In addition, with the development of technology and the replacement of hardware equipment, it may be necessary to upgrade or expand the electronic system. By replacing the adapter board 20 or the power backplane 30 with different functions or interfaces, the system upgrade and expansion can be easily achieved without making large-scale changes to the entire system. In addition, the plug-in design of the female connector 21 and the male connector 31 makes the installation process of the adapter board 20 and the power backplane 30 simple and quick. Only the male connector 31 needs to be aligned with the female connector 21 and gently inserted to complete the installation, without the need for complicated debugging and calibration processes.
[0037] In one embodiment, the female connector 21 is vertically arranged, the male connector 31 is horizontally arranged, and the male connector 31 is plugged into the female connector 21 from top to bottom, so that the power backplane 30 is perpendicular to the adapter board 20 .
[0038] Specifically, by setting the power backplane 30 to be perpendicular to the adapter board 20, space can be used more effectively. This vertical layout helps to reduce the horizontal area occupied by the equipment, so that the entire system can be installed more compactly in a limited space. In electronic equipment or systems, space is often a valuable resource. The vertical installation method can make the connection between the power backplane 30 and the adapter board 20 more compact, thereby saving more space for other components. In addition, when the power backplane 30 is installed perpendicular to the adapter board 20, the connection point between the two (i.e., the plug-in point of the female connector 21 and the male connector 31) will be subjected to a more uniform force distribution. This uniform force state helps to improve the strength and stability of the connection structure and reduce the risk of loose connection or damage due to vibration or external force. In the case of horizontal installation, the connection point may produce stress concentration due to gravity or other external factors, while vertical installation helps to disperse these stresses, making the connection point more stable and reliable.
[0039] In one embodiment, a metal spring piece is provided inside the female connector 21, and the male connector 31 is provided with a metal protrusion corresponding to the metal spring piece.
[0040] Specifically, the arrangement of the metal spring piece and the metal protrusion enables a stable electrical connection to be formed between the female connector 21 and the male connector 31. When the male connector 31 is inserted into the female connector 21, the metal protrusion comes into contact with the metal spring piece, thereby establishing a conductive path that allows current and signals to freely transmit between the two. Metal has good electrical conductivity, so the use of the metal spring piece and the metal protrusion can ensure the stability and reliability of the electrical connection. This design helps to reduce resistance and improve the current transmission efficiency, thus meeting the power transmission requirements of electronic devices. In addition, the metal spring piece has a certain elasticity and resilience when subjected to external forces, and can closely adhere to the metal protrusion to form a stable connection structure. This design helps to prevent the male connector 31 from loosening or falling off in the female connector 21, ensuring the stability and reliability of the connection. In addition, the close fit of the metal spring piece and the metal protrusion can reduce electrical faults and damages caused by poor contact or loosening. This design helps to extend the service life of electronic devices and reduce the maintenance and replacement costs. In addition, the metal material has good corrosion resistance and oxidation resistance, and can maintain stable performance under different environmental conditions. Therefore, the design of the metal spring piece and the metal protrusion enables the female connector 21 and the male connector 31 to adapt to various harsh working environments, such as high temperature, humidity, corrosion, etc.
[0041] In one embodiment, the female connector 21 and the male connector 31 are respectively fixed to the adapter plate 20 and the power supply backplane 30 by screws.
[0042] Specifically, as a fastener, the screw has a strong fastening force. By fixing the female connector 21 to the adapter plate 20 and the male connector 31 to the power supply backplane 30 with screws, it can be ensured that these connectors will not loosen or fall off due to external forces such as vibration and impact during the operation of the device. A stable connection is crucial for the normal operation of the device. The screw fixing method can effectively reduce electrical faults and signal interruptions caused by unstable connections, and improve the stability and reliability of the entire device. In addition, the screw fixing method is relatively simple and does not require complex tools or skills to complete the installation, which helps to reduce the assembly cost and time of the device and improve the production efficiency; when the connector needs to be replaced or repaired, simply loosening the screw can easily disassemble it without damaging other components or structures, which helps to reduce the maintenance cost and improve the maintainability of the device.
[0043] In one embodiment, the female connector 21 and the male connector 31 are respectively welded and fixed to the adapter plate 20 and the power supply backplane 30.
[0044] Specifically, welding is a method of connecting two or more metal parts by melting the material and resolidifying it. Welding connections usually have higher strength and rigidity than mechanical connections (such as screw fixing) because welding can form a continuous metal structure and reduce stress concentration at the connection. Compared with screw fixing, welding fixing can ensure that the female connector 21 and the male connector 31 form a permanent connection with the adapter plate 20 and the power backplane 30, greatly reducing the risk of loosening due to external forces such as vibration and impact. In addition, welding fixing can ensure that the electrical connection between the female connector 21 and the male connector 31 and the adapter plate 20 and the power backplane 30 has a good contact area and conductivity, thereby reducing the problems of poor contact and increased resistance. In addition, welding connections usually have better corrosion resistance than mechanical connections because welding can form a dense oxide layer to protect the connection parts from corrosion. In high temperature environments, welding connections can usually maintain good strength and stability and are not easily loosened or failed due to temperature changes.
[0045] In one embodiment, the adapter board 20 is electrically connected to the power backplane 30 via wires.
[0046] Specifically, electrical connection through wires can ensure that electric energy is stably and reliably transmitted to the adapter board 20, and then supplied to other electronic components or devices connected thereto. In addition, in addition to power transmission, the electrical connection between the adapter board 20 and the power backplane 30 may also carry the function of signal transmission. In some electronic devices, the power backplane 30 may not only provide power, but also be responsible for transmitting control signals or status information. Through wire connection, these signals can be smoothly transmitted between the adapter board 20 and the power backplane 30 to achieve overall control and coordination of the device. In addition, the existence of the adapter board 20 can also enhance the compatibility between different devices or modules. Since the adapter board 20 usually has a variety of interfaces and connection options, it can be connected to the power backplane 30 of different specifications or types through wires, so as to adapt to different power supply and signal transmission requirements. In addition, the detachable and replaceable electrical connection between the adapter board 20 and the power backplane 30 helps to realize the modular design of the system. This design allows each part of the system to be independently upgraded, replaced or maintained without large-scale changes to the entire system. In addition, with the continuous development of technology and the continuous changes in application requirements, electronic equipment or systems may need to be continuously updated and upgraded. Through the flexible connection between the adapter board 20 and the power backplane 30, new functional modules or devices can be easily introduced to adapt to future needs and development trends.
[0047] In one embodiment, the number of the CRPS power connectors is 2, and the number of the CRPS power interfaces is 4.
[0048] Specifically, in high-demand computing and data processing environments such as servers and data centers, the stability of the system is crucial. By increasing the number of CRPS power interfaces, the system can be configured with more redundant power modules, ensuring stable operation even if some power modules fail and reducing the risk of system downtime caused by power failures. In addition, each CRPS power module has a certain power supply capacity. When multiple power modules are configured in the system, the total power supply capacity will be increased. Therefore, having 4 CRPS power interfaces can support application scenarios with higher loads, ensuring stable operation of the system under high loads. Additionally, as technology continues to progress and application requirements continue to grow, the load of the system may gradually increase. By reserving a sufficient number of CRPS power interfaces, it is convenient to add power modules to meet future expansion needs and avoid restricting the development of the system due to insufficient power supply.
[0049] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
