[0030] See also Figures 1 to 4 In the specific embodiment shown, the utility model discloses a detachable PDB module mounting structure, including: a mounting bracket 10, a PDB board 20 and an L-shaped flexible metal conductive block 30, the number of the flexible metal conductive blocks 30 is two, the flexible metal conductive blocks 30 are connected to the PDB board 20, and the PDB board 20 is connected to the mounting bracket 10.

[0031] Specifically, by designing a detachable PDB module installation structure, when installing two conventional CRPS power supplies, one power supply is directly connected to the mainboard, and the other power supply is connected to the PDB module installation structure, and then the PDB module installation structure is connected to the mainboard; when only one CRPS power supply or 54V power supply is needed, the power supply can be directly connected to the mainboard, and the PDB module installation structure is not required. The PDB module installation structure can be flexibly matched according to the configuration to reduce the cost of the entire machine.

[0032] More specifically, this structure allows users to flexibly configure the power supply according to actual needs. When two CRPS power supplies are needed, one power supply is directly connected to the mainboard, and the other is indirectly connected to the mainboard through the PDB module mounting structure. This design provides flexibility in power supply usage. When only one CRPS power supply or 54V power supply is needed, the user can directly connect the power supply to the mainboard without using the PDB module mounting structure. This design avoids unnecessary hardware use, thereby helping to reduce the cost of the entire machine. In addition, the PDB module mounting structure is designed to be detachable, which means that users can relatively easily install or remove the PDB board 20 and its associated flexible metal conductive block 30. This design simplifies the maintenance process and makes it more convenient to replace or upgrade the power distribution system when needed. In addition, because the PDB module mounting structure can be flexibly matched according to the configuration, it improves the scalability of the entire system. As system requirements change, users can easily add or remove the PDB module mounting structure to adapt to different power requirements.

[0033] In one embodiment, the flexible metal conductive block 30 includes a first end 31 and a second end 32 , wherein the first end 31 and the second end 32 are connected to form an L shape, wherein the first end 31 is connected to the PDB board 20 , and the second end 32 is used to connect to an external main board.

[0034] Specifically, the first end 31 and the second end 32 can be bent and deformed to fine-tune the angle. The first end 31 and the second end 32 of the flexible metal conductive block 30 are connected to form an L-shape. This design allows the conductive block to provide a flexible connection solution within a limited space. Furthermore, the bendability between the first end 31 and the second end 32 means that the conductive block can fine-tune its angle as needed to accommodate different installation conditions and space constraints. Furthermore, during the electronic product manufacturing process, various factors (such as materials, processes, and equipment precision) often result in manufacturing tolerances. These tolerances can cause loose fits or gaps between components, thereby affecting the stability and reliability of the electrical connection. Due to its bendable and deformable nature, the flexible metal conductive block 30 can effectively absorb these manufacturing tolerances. When there are slight dimensional differences or positional deviations between the PDB board 20 and the external mainboard or mounting bracket 10, the conductive block can adapt to these differences through deformation, ensuring the stability and reliability of the electrical connection. Furthermore, during the electronic product assembly process, the interaction and coordination between components may generate certain assembly stresses, which can cause component deformation, damage, or poor electrical connections. The flexible metal conductive block 30 can absorb and disperse these assembly stresses. When the PDB board 20 is connected to the external main board through the conductive block, even if there is a certain stress, the conductive block can buffer and disperse these stresses through its deformation, thereby protecting the components from damage and ensuring the stability of the electrical connection.

[0035] In one embodiment, the first end 31 defines at least one connecting hole 311 , and the connecting hole 311 is in an oblong shape.

[0036] Specifically, the number of the connecting holes 311 is two, and the design of the oblong connecting holes 311 is used to solve manufacturing tolerance and assembly problems.

[0037] More specifically, when there are two connection holes 311, the connection stability and reliability between the flexible metal conductive block 30 and the PDB board 20 or other components can be further enhanced. The two connection holes 311 provide more connection points and support, making the entire connection structure more secure and stable. At the same time, the two connection holes 311 can also disperse assembly stress to a certain extent, preventing connection failure or damage caused by stress concentration. The design of the oblong connection holes 311 is primarily to address manufacturing tolerances and assembly issues. During the manufacturing and assembly of electronic products, due to various factors, there are often certain dimensional differences and positional deviations between components. If these differences and deviations are not effectively addressed, they may lead to a loose fit between components, affecting the stability and reliability of the electrical connection. Compared to circular or other shaped connection holes 311, the oblong connection holes 311 have a larger size adjustment range. When the PDB board 20 or other components are connected to the first end 31 of the flexible metal conductive block 30, even if there are certain dimensional differences, the oblong connection holes 311 can absorb these differences through their shape characteristics, ensuring a tight fit between the components. In addition, the oblong-shaped connection hole 311 makes the assembly process more flexible and convenient. The assembler can fine-tune the position and angle of the component according to actual conditions to ensure the best assembly effect and electrical connection performance, which helps to improve assembly efficiency and reduce assembly difficulty.

[0038] In one embodiment, the second end 32 defines at least one connecting hole 311 , and the connecting hole 311 is in an oblong shape.

[0039] Specifically, the number of the connecting holes 311 is two, and the design of the oblong connecting holes 311 is used to solve manufacturing tolerance and assembly problems.

[0040] More specifically, when there are two connection holes 311, the connection stability and reliability between the flexible metal conductive block 30 and the motherboard or other components can be further enhanced. The two connection holes 311 provide more connection points and support, making the entire connection structure more secure and stable. At the same time, the two connection holes 311 can also disperse assembly stress to a certain extent, preventing connection failure or damage caused by stress concentration. The design of the oblong connection hole 311 is primarily to address manufacturing tolerances and assembly issues. During the manufacturing and assembly of electronic products, due to various factors, there are often certain dimensional differences and positional deviations between components. If these differences and deviations are not effectively addressed, they may lead to a loose fit between components, affecting the stability and reliability of the electrical connection. Compared to circular or other shaped connection holes 311, the oblong connection hole 311 has a larger size adjustment range. When the motherboard or other component is connected to the second end 32 of the flexible metal conductive block 30, even if there are certain dimensional differences, the oblong connection hole 311 can absorb these differences through its shape characteristics, ensuring a tight fit between the components. In addition, the oblong-shaped connection hole 311 makes the assembly process more flexible and convenient. The assembler can fine-tune the position and angle of the component according to actual conditions to ensure the best assembly effect and electrical connection performance, which helps to improve assembly efficiency and reduce assembly difficulty.

[0041] In one embodiment, the first end 31 and the second end 32 are integrally formed.

[0042] Specifically, the first end 31 and the second end 32 are connected by one-piece molding technology to form an integral structure, which avoids the problems of reduced strength and stress concentration at the connection that may be caused by traditional connection methods (such as welding, bolt connection, etc.). In addition, the one-piece molding structure can ensure that the connection between the first end 31 and the second end 32 is more secure, thereby improving the strength and stability of the entire structure. In addition, due to the improved strength of the connection, the risk of failure due to connection failure is reduced, and the reliability and service life of the product are improved. In addition, the one-piece molding technology can simplify the production process, reduce the number of parts and assembly steps, thereby shortening the production cycle. By reducing material waste and labor costs in the production process, the one-piece molding structure helps to reduce production costs.

[0043] In one embodiment, the two flexible metal conductive blocks 30 are respectively a positive electrode block and a negative electrode block, and the positive electrode block and the negative electrode block are further connected to a sleeve 33 for distinguishing between positive and negative electrodes.

[0044] Specifically, the sleeve 33 includes a red sleeve and a black sleeve. The positive electrode block is enclosed in a red sleeve, and the negative electrode block is enclosed in a black sleeve, so that users can quickly distinguish between the positive and negative poles. In other words, the red and black sleeves serve as intuitive visual identifiers, allowing users to quickly distinguish between the positive and negative poles when connecting a power source or electronic device. The color distinction greatly reduces the risk of circuit failure or equipment damage caused by incorrect connection of the positive and negative poles. In addition, correctly distinguishing between the positive and negative poles is a key step in preventing circuit short circuits. This technology ensures that users can accurately connect through the color sleeve 33, thereby improving the safety and reliability of the circuit. Incorrect positive and negative pole connections may cause damage or burning of internal components of the device. The color sleeve 33 distinction can effectively avoid this situation and protect the normal operation of the device. In addition, users do not need to use complex markings or tests to determine the positive and negative poles. They can quickly connect according to the color sleeve 33. In situations where frequent connection and disconnection of the power supply are required, this technology can significantly improve work efficiency and reduce operation time.

[0045] In one embodiment, the flexible metal conductive block 30 is made of copper.

[0046] Specifically, copper is a very good electrical conductor with extremely low resistivity and good conductive stability. Therefore, the flexible metal conductive block 30 made of copper metal can ensure the high efficiency and stability of current during transmission, reduce energy loss and signal attenuation. In addition, copper metal has good ductility and plasticity, and is easy to be processed into various shapes and sizes to meet the needs of the flexible metal conductive block 30 in different application scenarios. At the same time, the density of copper is moderate, and it is neither too heavy to affect the portability of the device, nor too light to affect the stability of the structure. In addition, copper metal has good corrosion resistance and oxidation resistance, and can maintain its conductive properties and structural integrity in a variety of harsh environments, which helps to extend the service life of the flexible metal conductive block 30 and reduce performance degradation or failures caused by environmental factors.

[0047] In one embodiment, the PDB board 20 is provided with an inserting port 21 , and the mounting bracket 10 is provided with an opening 11 corresponding to the inserting port 21 , so that the inserting port 21 passes through the opening 11 .

[0048] Specifically, the design of the plug interface 21 on the PDB board 20 (power distribution board) allows the power supply to be conveniently connected to the PDB board 20 by plugging. This connection method is not only easy to operate, but also ensures a stable and reliable electrical connection between the power supply and the PDB board 20. At the same time, the plug interface 21 generally has good electrical conductivity and anti-interference capabilities, which can ensure stable current transmission and clear signal transmission. In addition, through the design of the plug interface 21 and the corresponding opening 11, the PDB board 20 can be easily assembled and disassembled with the mounting bracket 10, thereby improving the flexibility and scalability of the entire system; when it is necessary to replace the power supply or upgrade the circuit board, simply disconnect the plug interface 21 to complete the replacement or upgrade operation, without the need for large-scale disassembly and reconstruction of the entire system. In addition, the design of the plug interface 21 and the opening 11 not only facilitates power connection, but also can ensure the safety and stability of the system to a certain extent. The plug interface 21 generally has a fool-proof design and overcurrent protection function, which can avoid problems such as incorrect connection and overcurrent damage.

[0049] In one embodiment, the mounting bracket 10 is provided with at least one guide post 12 , and the PDB board 20 is provided with a guide hole 22 corresponding to the guide post 12 .

[0050] Specifically, the design of the guide posts 12 and guide holes 22 allows for more precise installation of the PDB board 20 on the mounting bracket 10. During assembly, the guide posts 12 can guide the PDB board 20 to accurately align and position it to the predetermined position, thus avoiding assembly difficulties or poor electrical connections caused by positional deviations. Furthermore, the design of the guide posts 12 and guide holes 22 not only simplifies the assembly process but also improves assembly efficiency. Traditional assembly methods may require complex adjustment and calibration steps, while the design of the guide posts 12 and guide holes 22 makes the assembly process more intuitive and simple. Simply align the guide holes 22 on the PDB board 20 with the guide posts 12 on the mounting bracket 10 and gently push them together, significantly saving assembly time and labor costs. In addition, the cooperation between the guide column 12 and the guide hole 22 can also enhance the structural stability between the PDB board 20 and the mounting bracket 10. Once the PDB board 20 is correctly installed on the mounting bracket 10, the guide column 12 will play a supporting and fixing role to prevent the PDB board 20 from moving or deforming during use. This structural stability is crucial to ensuring the reliability of the electrical connection and the long-term stable operation of the equipment.

[0051] In one embodiment, guide grooves 13 are further provided on both sides of the mounting bracket 10 .

[0052] See also Figure 3 and Figure 4In the application scenario of the PDB module mounting structure shown, the chassis is provided with guide pins corresponding to the guide grooves 13. The matching design of the guide grooves 13 and the guide pins greatly simplifies the disassembly and assembly process of the PDB module mounting structure. During the disassembly and assembly process, the user only needs to slide the PDB module mounting structure along the direction of the guide grooves 13 to align the guide pins with the guide grooves 13 and insert them. This design avoids the complex adjustment and calibration steps that may be required in traditional disassembly and assembly methods, thereby improving disassembly and assembly efficiency. In addition, the matching of the guide grooves 13 and the guide pins can also improve the accuracy of disassembly and assembly. Since the shapes and sizes of the guide grooves 13 and the guide pins are precisely designed, the matching between them can ensure the position accuracy of the PDB module mounting structure during the installation process, which helps to avoid problems such as poor electrical connection or mechanical damage caused by position deviation. In addition, the design of the guide grooves 13 and the guide pins can also enhance the structural stability between the PDB module mounting structure and the chassis. Once the PDB module mounting structure is correctly installed on the chassis, the matching of the guide grooves 13 and the guide pins will play a supporting and fixing role, preventing the PDB module mounting structure from moving or deforming during use. This structural stability is crucial to ensuring the reliability of electrical connections and the long-term stable operation of the equipment.

[0053] Specifically, the PDB board 20 is installed on the front of the mounting bracket 10. A connecting plate is provided on the top of the mounting bracket 10. The connecting plate is used to connect to the chassis through screws to achieve rapid disassembly and assembly of the PDB module mounting structure, solving the problem caused by excessive stroke of the motherboard during installation, and avoiding the problem of sideways screwing inside the chassis.

[0058] Specifically, the PDB module is fixed to the front of the mounting bracket using screws to form a PDB module mounting structure. In subsequent use, the PDB module mounting structure is mounted to the chassis using screws, and then the flexible metal conductive block is connected to the mainboard using screws.
