Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] This application provides a power adapter, such as... Figures 1 to 5 As shown, it includes a mounting plate 1 and a housing 2. The mounting plate 1 and the housing 2 are interlocked to form a mounting cavity, and a PCB assembly 3 is mounted inside the mounting cavity. The edge of the mounting plate 1 has a first fixing hole 1a and a second fixing hole 1b. These fixing holes are used to insert fasteners (such as screws) to fix the power adapter to the cabinet. To improve installation accuracy and fault tolerance, the diameters of the first fixing hole 1a and the second fixing hole 1b are set differently along different directions. Specifically, the diameter of the first fixing hole 1a along the second direction y is larger than the diameter along the first direction x, and the diameter of the second fixing hole 1b along the second direction y is smaller than the diameter along the first direction x. The first direction x, the second direction y, and the thickness direction of the mounting plate 1 are perpendicular to each other. For example, assuming the mounting plate 1 is a rectangular plate, then the first direction x is the length direction of the mounting plate 1, and the second direction y is the width direction of the mounting plate 1.

[0040] This design, by rationally setting the differences in hole diameter in different directions, allows the power adapter to flexibly handle errors in the position of the cabinet door holes during installation. Specifically, the design of the first fixing hole 1a allows for offset adjustment along the second direction y, while the second fixing hole 1b allows for similar offset adjustment in the first direction x. Thus, even if the positional error of the cabinet door hole is large, the power adapter can still be adjusted by offsetting the hole positions, ensuring a smooth installation process and avoiding rework or scrap due to excessive hole position errors, significantly reducing installation costs.

[0041] During actual installation, firstly, move the power adapter along the first direction x to ensure that the first fixing hole 1a is aligned with the hole in the cabinet along the first direction x. Then, move the power adapter along the second direction y to ensure that the second fixing hole 1b is aligned with the hole in the cabinet along the second direction y. Alternatively, you can first move the power adapter along the second direction y to ensure that the second fixing hole 1b is aligned with the hole in the cabinet along the second direction y, and then adjust the position of the power adapter along the first direction x to ensure that the second fixing hole 1b is completely aligned with the hole in the cabinet. After completing the above steps, pass the fastener through the first fixing hole 1a and fix it to the cabinet. At this point, the power adapter can be initially hung on the cabinet. Finally, pass the fastener through the second fixing hole 1b and fix it to the cabinet for final fixation to ensure that the power adapter is securely installed. It should be noted that the mounting plate 1 and the cover 2 can be made of molded plastic parts to give them good insulation and safety performance.

[0042] Overall, this installation method is simple and intuitive, ensuring high installation accuracy and significantly improving fault tolerance during the installation process. Compared with traditional installation methods, the installation method provided in this application has significant advantages. The operation process is easy to master, and can even be completed independently by an individual, thereby effectively reducing labor installation costs and improving installation efficiency. Furthermore, since this design can successfully complete installation even with large errors in cabinet door hole positions, it further reduces rework or scrap rates caused by inaccurate hole positions, lowers production costs, and enhances the application value of the product.

[0043] Optionally, such as Figure 2As shown, the first fixing hole 1a includes an oblong hole and an arc-shaped hole connected sequentially along the second direction y. The diameter of the arc-shaped hole along the first direction x is larger than that of the oblong hole along the first direction x. The oblong hole has a smaller diameter along the first direction x, while the arc-shaped hole has a larger diameter along the first direction x, forming a gradually expanding transition structure. Using this arc-shaped hole, screws can be pre-screwed in, and then the power adapter can be pre-mounted on the cabinet through the arc-shaped hole for subsequent fixing, thus enabling independent installation and reducing labor costs. Preferably, the arc-shaped hole is a round hole. This structural design allows the fixing component to have greater movement space in the first direction x during installation, effectively accommodating errors in the cabinet door hole positions and ensuring that the fixing component can pass smoothly and accurately align with the cabinet's holes during installation.

[0044] Furthermore, the combination of the arc-shaped and oblong holes not only enhances the tolerance of the first fixing hole 1a but also optimizes installation stability. When the first fixing hole 1a of the power adapter is not perfectly aligned with the hole in the cabinet, the larger diameter of the arc-shaped hole allows for more adjustment space for the fastener, preventing issues such as inability to fix it properly or installation difficulties due to minor errors. This structural design effectively avoids installation difficulties caused by hole misalignment, thereby further simplifying the installation process, improving installation efficiency, reducing the possibility of rework and scrap, and lowering production costs.

[0045] Optionally, such as Figure 2 As shown, the second fixing hole 1b is an oblong hole. Combined with the design of the first fixing hole 1a, the overall solution improves fault tolerance and ensures stable installation of the power adapter. The first fixing hole 1a consists of an oblong hole and a circular hole, providing a large adjustment space along the second direction y and a certain degree of fault tolerance in the first direction x, effectively accommodating errors in the cabinet hole positions. The second fixing hole 1b, with its oblong hole design, provides additional adjustment space along the first direction x. Working in conjunction with the first fixing hole 1a, it allows the fastener to tolerate certain errors during installation and precisely align with the cabinet hole positions.

[0046] Optionally, such as Figure 1 and Figure 2 As shown, there are at least two first fixing holes 1a, which are located on both sides of the mounting plate 1 along the first direction x. This design ensures better stability of the power adapter during installation because by placing the first fixing holes 1a on both sides of the mounting plate 1, the stress during installation can be evenly distributed, thereby effectively preventing displacement or instability caused by uneven fixing.

[0047] Optionally, such as Figure 1 and Figure 2As shown, there are at least two second fixing holes 1b, located on both sides of the mounting plate 1 along the first direction x. By placing the second fixing holes 1b on both sides of the mounting plate 1, the stability of the power adapter during installation can be further enhanced. The second fixing holes 1b on both sides effectively distribute the fixing force, ensuring that the power adapter is evenly stressed during installation, thereby avoiding displacement or instability caused by uneven fixing. This design not only improves the connection stability between the power adapter and the cabinet, but also ensures the stability of the power adapter during long-term use.

[0048] Optionally, such as Figure 1 and Figure 2 As shown, two first fixing holes 1a and two second fixing holes 1b are provided on the edge of the mounting plate 1. The arrangement of the two first fixing holes 1a and the two second fixing holes 1b can effectively enhance the installation stability and accuracy of the power adapter, ensure the uniform force on the fixing parts and avoid displacement or instability.

[0049] Specifically, two first fixing holes 1a are arranged along the first direction x on both sides of the mounting plate 1, and two second fixing holes 1b are also arranged along the first direction x on both sides of the mounting plate 1. The two first fixing holes 1a are located on one side of the mounting plate 1 along the second direction y, while the two second fixing holes 1b are located on the other side of the mounting plate 1 along the second direction y. By arranging the fixing holes at the four corners of the mounting plate 1, it can be ensured that the four corners can share the force generated during the installation process when fixing the power adapter. This design not only improves the stability of the installation, but also effectively prevents the offset or loosening caused by the mounting holes being too concentrated or unevenly stressed, ensuring the stability of the connection between the power adapter and the cabinet.

[0050] Optionally, such as Figures 6 to 8 As shown, a third fixing hole 2a and a fourth fixing hole 2b are respectively provided on the corresponding edges of the cover 2 and the mounting plate 1. Fixing members are sequentially inserted through the third fixing hole 2a and the first fixing hole 1a to secure them to the cabinet, and sequentially inserted through the fourth fixing hole 2b and the second fixing hole 1b to secure them to the cabinet. The shape, position, and size of the third fixing hole 2a correspond perfectly to the first fixing hole 1a, and the shape, position, and size of the fourth fixing hole 2b correspond to the second fixing hole 1b, ensuring that the fixing members can accurately pass through the fixing holes, thereby achieving a firm connection between the cover 2, the mounting plate 1, and the cabinet. This fixing method not only effectively ensures a tight connection between the mounting plate 1 and the cabinet, but also firmly connects the cover 2 and the mounting plate 1, improving the overall stability of the power adapter structure. This design, through reasonable hole placement and the sequence of fixing member insertion, creates multiple fastening connections between the power adapter's cover 2, the mounting plate 1, and the cabinet, enhancing the synergy between the various parts.

[0051] Furthermore, this multi-point fixing design not only strengthens the secure connections between components but also improves the overall structure's shock resistance and durability. Even under external forces or vibrations, the connections between the housing 2, mounting plate 1, and cabinet remain secure, preventing the risk of loosening or detachment. Therefore, this design, by reinforcing multi-point connections, enhances the overall stability and reliability of the power adapter, ensuring its excellent performance during long-term use.

[0052] Optionally, such as Figure 2 and Figure 3 As shown, a first connecting hole 1c is provided on the mounting plate 1, and a second connecting hole 2c is provided on the cover 2. The diameter of the second connecting hole 2c along the first direction x is larger than that of the first connecting hole 1c along the first direction x, thereby providing greater tolerance for the installation process. This difference in hole diameter ensures that during the fixing process, the first connector can be properly aligned and adjusted in the second connecting hole 2c to smoothly pass through the first connecting hole 1c, thereby sequentially passing through the second connecting hole 2c and the first connecting hole 1c to securely fasten the cover 2 to the mounting plate 1.

[0053] In practical implementation, the first connector uses a screw, and the first connecting hole 1c is designed as a threaded hole with a diameter precisely matched to the screw diameter, allowing the screw to fit tightly into the threaded hole and ensuring a stable connection. This threaded connection method provides good tensile strength and durability, ensuring the stability and reliability of the power adapter during long-term use. Meanwhile, the second connecting hole 2c adopts an oblong hole design. The diameter of the oblong hole along the second direction y is the same as that of the first connecting hole 1c, while the diameter along the first direction x is larger than that along the second direction y. This oblong hole design not only ensures that the first connector can pass smoothly but also increases the tolerance space, providing sufficient adjustment leeway when there are errors in the hole position, ensuring that the fastening installation of the cover 2 and the mounting plate 1 is not affected by hole position errors.

[0054] Optionally, first connecting holes 1c are respectively provided on both sides of the mounting plate 1 along the second direction y, and second connecting holes 2c are respectively provided on both sides of the cover 2 along the second direction y. The first connecting holes 1c on both sides of the mounting plate 1 are asymmetrical along the first direction x, and the second connecting holes 2c on both sides of the cover 2 are asymmetrical along the first direction x. For example, two first connecting holes 1c are respectively provided on both sides of the mounting plate 1 along the second direction y, and two second connecting holes 2c are respectively provided on both sides of the cover 2 along the second direction y. The distance between the two first connecting holes 1c on one side of the mounting plate 1 along the second direction y is different from the distance between the two first connecting holes 1c on the other side of the mounting plate 1 along the second direction y. Correspondingly, the distance between the two second connecting holes 2c on one side of the cover 2 along the second direction y is different from the distance between the two second connecting holes 2c on the other side of the cover 2 along the second direction y, thereby achieving a foolproof design and ensuring that the cover 2 and the mounting plate 1 can only be fastened and installed in the correct direction. The foolproof design effectively prevents installation errors caused by incorrect installation orientation, and prevents product damage or unstable installation due to improper human operation. This asymmetrical design ensures precise alignment of each fixing point, avoiding potential errors during installation and improving installation accuracy and efficiency.

[0055] Optionally, such as Figure 7 and Figure 8 As shown, a third connecting hole 1d is provided on the mounting plate 1, and a fourth connecting hole 2d is provided on the cover 2. The third connecting hole 1d is a conical through hole, the minimum diameter of which is the same as the diameter of the fourth connecting hole 2d, matching the diameter of the first connector. Furthermore, the fourth connecting hole 2d is a threaded hole, allowing the first connector to pass through the third connecting hole 1d and be threadedly connected to the fourth connecting hole 2d, thereby securely fastening the cover 2 to the mounting plate 1. Similarly, if the number of third connecting holes 1d and fourth connecting holes 2d exceeds one, the foolproof design function must still be maintained.

[0056] Optionally, such as Figure 2 As shown, the mounting plate 1 includes a snap-fit ​​plate 11 and a bent plate 12 connected in sequence, with the bent plate 12 perpendicular to the snap-fit ​​plate 11. Specifically, the snap-fit ​​plate 11 faces the front of the housing 2, while the bent plate 12 fits tightly against the side of the housing 2. This design ensures that the mounting plate 1 can be stably connected to the housing 2, while completing the secure installation of the power adapter without affecting the front appearance.

[0057] In this design, the first connecting hole 1c is located on the bent plate 12, while the second connecting hole 2c is located on the side of the housing 2. This placement ensures that the arrangement of the connecting holes is closely integrated with the appearance of the power adapter, while avoiding any disruption to the front aesthetics. The vertical arrangement of the bent plate 12 and the fastening plate 11 allows the connecting holes to be positioned along the side, enabling the first connector to pass smoothly through these holes and achieve a stable fastening process. Furthermore, because the connecting holes are located in a less conspicuous location, the fastening of the mounting plate 1 and the housing 2 does not interfere with the power adapter's appearance design, resulting in a simpler and more modern look. This achieves a secure yet aesthetically pleasing installation solution.

[0058] Optionally, such as Figure 4 and Figure 9 As shown, in order to achieve stable placement of the PCB assembly 3 within the mounting cavity, a first mounting hole 3a is provided on the PCB assembly 3, and a first boss 21 extending toward the PCB assembly 3 is provided on the side of the housing 2 opposite to the mounting plate 1. The design of this boss can provide a precise position for the second mounting hole 2e, ensuring that the second mounting hole 2e can mate with the first mounting hole 3a, thereby securing the PCB assembly 3 firmly within the housing 2 via the second connector.

[0059] Specifically, the first boss 21 extends along the inner side of the housing 2 and has a second mounting hole 2e. The second connector is a screw, and the second mounting hole 2e is a threaded hole with a diameter matching the screw to ensure a tight fit. The screw passes through the first mounting hole 3a and the second mounting hole 2e in sequence, thereby firmly fixing the PCB assembly 3 inside the housing 2. This design ensures that the PCB assembly 3 is in the correct position within the mounting cavity, preventing loosening of electrical connections due to vibration or external forces, thus guaranteeing electrical safety and equipment reliability during use. Furthermore, the boss design not only effectively secures the PCB assembly 3 but also avoids the complexity of the external structure, maintaining the power adapter's simple and aesthetically pleasing appearance.

[0060] Optionally, there are at least two first mounting holes 3a, and these at least two first mounting holes 3a are asymmetrical along both the second direction y and the first direction x. Correspondingly, there are at least two second mounting holes 2e, and these at least two second mounting holes 2e are asymmetrical along both the second direction y and the first direction x. Multi-hole mounting enhances the stability of the PCB assembly 3. The asymmetrical design prevents installation errors caused by incorrect connection methods or incorrect orientation selection, achieving a foolproof design. This foolproof design simplifies and streamlines the installation process of the power adapter, reducing rework and scrap rates due to human error, thereby lowering production costs.

[0061] Optionally, the PCB assembly 3 includes a PCB board 31 mounted within the mounting cavity and multiple sets of connectors 32 disposed on the PCB board 31, such as... Figure 5 , Figure 10 and Figure 11 As shown, multiple wiring holes 2f are provided on the side of the cover 2 opposite to the mounting plate 1 (i.e., the front side of the cover 2), or, as... Figure 12 As shown, multiple wiring holes 2f are provided on the side of the housing 2 opposite to the mounting plate 1 and on the side of the housing 2. Multiple sets of plugs 32 are used to pass through different wiring holes 2f to connect to different power supplies, thereby realizing the multi-power supply adaptation function. The wiring holes 2f on the housing 2 can adopt a centralized partition layout, dividing the housing 2 into an information input area, a sampling input area, and an information output area, so as to clearly classify and manage the power connections.

[0062] Multiple sockets 2f are arranged in different areas according to their functions, ensuring that each socket 2f has a specific purpose. For example, the information input area has five sockets 2f for connecting three power switches and two bus tie switches to obtain the operating status information of the power switches. The sampling input area has three sockets 2f for connecting three power switches to obtain power status parameter information. The information output area has four sockets 2f for connecting the controller and the power module. The power module is responsible for providing power to different power sources according to the controller's selection and for powering the controller. The controller, in turn, makes judgments based on the input status information and controls the on / off state of the power switches and bus tie switches.

[0063] This design not only integrates three power supply information channels and five signal information channels, but also simplifies the user wiring process by using a single integrated power adapter and pre-fabricated wiring harness. This enables the power adapter to adapt to multiple power sources and provides a more convenient and faster wiring method. Furthermore, the power module selected for system power supply can be a standalone module or integrated into the power adapter, offering users greater flexibility and scalability.

[0064] To further improve the ease of use and accuracy of operation of the power adapter, different markings 22 can be placed on one side of each plug hole 2f. These markings 22 allow users to accurately insert each cable into the corresponding plug hole 2f during wiring, avoiding potential problems caused by incorrect wiring. This design not only improves installation efficiency but also effectively reduces the risk of system failure due to incorrect wiring, ensuring the power adapter functions properly and guaranteeing electrical safety. Furthermore, the pre-defined markings 22 allow users to easily complete wiring operations without the need for complex manuals or diagrams, greatly simplifying the installation process and enhancing the user experience.

[0065] To further improve the performance of the power adapter, multiple relays 4 are designed on the PCB board 31. These relays 4 can integrate and extend the signals input to the PCB assembly 3. By setting up the relays 4, the interlocking distance between multiple signals is greatly reduced, thereby reducing interference and instability in signal transmission. This not only improves signal stability but also enhances the safety of signal conversion, ensuring reliable operation of the power adapter in complex electrical environments.

[0066] In summary, the power adapter provided in this application embodiment, through the reasonable layout of the plug hole 2f and the relay 4, can achieve multi-power supply adaptation function, and simplifies the wiring process through integrated design. The modular design and optimized signal management of the system can greatly improve the stability and safety of electrical connections, while also providing more flexible scalability and higher user-friendliness, offering users a simpler wiring and operation experience.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
