[0032] See also Figures 1 to 4 In the specific embodiment shown, the present invention discloses a detachable PDB module installation 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 block 30 is connected to the PDB board 20, and the PDB board 20 is connected to the mounting bracket 10.

[0033] Specifically, by designing a detachable PDB module installation structure, when two conventional CRPS power supplies are installed, one of the power supplies 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.

[0034] More specifically, the structure allows the user 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 the use of power supplies. 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 the user 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 necessary. 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.

[0035] 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.

[0036] 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 enables the conductive block to provide a flexible connection scheme in a limited space. In addition, the first end 31 and the second end 32 can be bent and deformed, which means that the conductive block can fine-tune its angle according to actual needs to adapt to different installation conditions and space limitations. In addition, in the manufacturing process of electronic products, due to the influence of various factors (such as materials, processes, equipment accuracy, etc.), there are often certain manufacturing tolerances, which may cause the components to fit together not tightly enough or there are gaps, thereby affecting the stability and reliability of the electrical connection. Due to its bendable and deformable characteristics, the flexible metal conductive block 30 can effectively absorb these manufacturing tolerances. When there are slight size differences or position deviations between the PDB board 20 and the external main board or the mounting bracket 10, the conductive block can adapt to these differences through its deformation to ensure the stability and reliability of the electrical connection. In addition, in the assembly process of electronic products, due to the interaction and cooperation between the components, certain assembly stresses may be generated, which may cause problems such as component deformation, damage or poor electrical connection. 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.

[0037] In one embodiment, the first end 31 is provided with at least one connecting hole 311 , and the connecting hole 311 is in an oblong shape.

[0038] Specifically, the number of the connecting holes 311 is 2, and the design of the connecting holes 311 in an oblong shape is used to solve the manufacturing tolerance and assembly problems.

[0039] More specifically, when the number of the connection holes 311 is 2, 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 can provide more connection points and support forces, making the entire connection structure more firm and stable. At the same time, the two connection holes 311 can also disperse the assembly stress to a certain extent to prevent the connection failure or damage caused by stress concentration. The design of the oblong connection hole 311 is mainly to deal with the problems in the manufacturing tolerance and assembly process. In the manufacturing and assembly process of electronic products, due to the influence of various factors, there are often certain size differences and position deviations between components. If these differences and deviations are not effectively solved, they may cause the components to fit together. Not tight enough, affecting the stability and reliability of the electrical connection. The oblong connection hole 311 has a larger size adjustment range than the circular or other shaped connection holes 311. 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 size differences, the oblong connection hole 311 can absorb these differences through its shape characteristics to ensure 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 the actual situation to ensure the best assembly effect and electrical connection performance, which helps to improve assembly efficiency and reduce assembly difficulty.

[0040] In one embodiment, the second end 32 is provided with at least one connecting hole 311 , and the connecting hole 311 is in an oblong shape.

[0041] Specifically, the number of the connecting holes 311 is 2, and the design of the connecting holes 311 in an oblong shape is used to solve the manufacturing tolerance and assembly problems.

[0042] More specifically, when the number of connection holes 311 is 2, the connection stability and reliability between the flexible metal conductive block 30 and the mainboard or other components can be further enhanced. The two connection holes 311 can provide more connection points and support forces, making the entire connection structure more firm and stable. At the same time, the two connection holes 311 can also disperse the assembly stress to a certain extent to prevent the connection failure or damage caused by stress concentration. The design of the oblong connection hole 311 is mainly to deal with the problems in the manufacturing tolerance and assembly process. In the manufacturing and assembly process of electronic products, due to the influence of various factors, there are often certain size differences and position deviations between components. If these differences and deviations are not effectively solved, they may cause the components to fit together. Not tight enough, affecting the stability and reliability of the electrical connection. The oblong connection hole 311 has a larger size adjustment range than the circular or other shaped connection holes 311. When the mainboard or other components are connected to the second end 32 of the flexible metal conductive block 30, even if there are certain size differences, the oblong connection hole 311 can absorb these differences through its shape characteristics to ensure 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 the actual situation to ensure the best assembly effect and electrical connection performance, which helps to improve assembly efficiency and reduce assembly difficulty.

[0043] In one embodiment, the first end 31 and the second end 32 are integrally formed.

[0044] 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, since the strength of the connection is improved, the risk of failure caused by 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.

[0045] 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 with a sleeve 33 for distinguishing between positive and negative electrodes.

[0046] Specifically, the sleeve 33 includes a red sleeve and a black sleeve. The positive block is provided with a red sleeve, and the negative block is provided with a black sleeve, so that the user can quickly distinguish the positive and negative poles. That is to say, the red sleeve and the black sleeve serve as intuitive visual identifiers, which enable the user to quickly distinguish the positive block and the negative block when connecting a power source or an electronic device. By distinguishing by color, the risk of circuit failure or equipment damage caused by misconnecting the positive and negative poles is greatly reduced. In addition, correctly distinguishing 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. By distinguishing by the color sleeve 33, this situation can be effectively avoided and the normal operation of the device can be protected. In addition, the user does not need to determine the positive and negative poles through complex markings or tests, but 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.

[0047] In one embodiment, the flexible metal conductive block 30 is made of copper.

[0048] Specifically, copper is an excellent 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.

[0049] In one embodiment, the PDB board 20 is provided with an insertion port 21 , and the mounting bracket 10 is provided with an opening 11 corresponding to the insertion port 21 , so that the insertion port 21 passes through the opening 11 .

[0050] 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 can ensure that the electrical connection between the power supply and the PDB board 20 is stable and reliable. At the same time, the plug interface 21 usually has good conductivity and anti-interference ability, which can ensure the stable transmission of current and the clear transmission of signals. 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, it is only necessary to simply disconnect the plug interface 21 to complete the replacement or upgrade operation without large-scale disassembly and reconstruction of the entire system. In addition, the design of the plug interface 21 and the opening 11 is not only convenient for power connection, but also can ensure the safety and stability of the system to a certain extent. The plug interface 21 usually has a fool-proof design and overcurrent protection function, which can avoid the occurrence of problems such as wrong connection and overcurrent damage.

[0051] In one embodiment, the mounting bracket 10 is provided with at least one guide column 12 , and the PDB board 20 is provided with a guide hole 22 corresponding to the guide column 12 .

[0052] Specifically, the matching design of the guide post 12 and the guide hole 22 makes the installation position of the PDB board 20 on the mounting bracket 10 more accurate. During the assembly process, the guide post 12 can guide the PDB board 20 to accurately align and position it to the predetermined position, avoiding problems such as assembly difficulties or poor electrical connection caused by position deviation. In addition, the matching of the guide post 12 and the guide hole 22 not only simplifies the assembly process, but also improves the assembly efficiency. The traditional assembly method may require complex adjustment and calibration steps, while the design of the guide post 12 and the guide hole 22 makes the assembly process more intuitive and simple. It is only necessary to align the guide hole 22 on the PDB board 20 with the guide post 12 on the mounting bracket 10, and then gently push it in, which greatly saves 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.

[0053] In one embodiment, guide grooves 13 are further provided on both sides of the mounting bracket 10 .

[0054] See also Figure 3 and Figure 4In the application scenario of the PDB module installation structure shown, the chassis is provided with a guide pin corresponding to the guide groove 13, and the matching design of the guide groove 13 and the guide pin greatly simplifies the disassembly and assembly process of the PDB module installation structure. During the disassembly and assembly process, the user only needs to slide the PDB module installation structure along the direction of the guide groove 13, so that the guide pin is aligned with the guide groove 13 and inserted. This design avoids the complex adjustment and calibration steps that may be required in the traditional disassembly and assembly method, and improves the disassembly and assembly efficiency. In addition, the matching of the guide groove 13 and the guide pin can also improve the accuracy of disassembly and assembly. Since the shape and size of the guide groove 13 and the guide pin are precisely designed, the matching between them can ensure the position accuracy of the PDB module installation 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 groove 13 and the guide pin can also enhance the structural stability between the PDB module installation structure and the chassis. Once the PDB module installation structure is correctly installed on the chassis, the matching of the guide groove 13 and the guide pin will play a supporting and fixing role, preventing the PDB module installation structure from moving or deforming during use. This structural stability is critical to ensuring the reliability of electrical connections and the long-term stable operation of the equipment.

[0055] Specifically, the PDB board 20 is installed on the front side of the mounting bracket 10. A connecting plate is provided on the top of the mounting bracket 10. The connecting plate is used to be connected to the chassis via screws to achieve rapid disassembly and assembly of the PDB module mounting structure, thereby solving the problem caused by excessive travel of the motherboard during installation and avoiding the problem of sideways screwing inside the chassis.

[0056] See also Figure 5 As shown, an embodiment of the present invention provides an assembly method of a detachable PDB module installation structure, comprising the following steps:

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.
