Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an expandable prefabricated modular cabinet PDU device. Background Technology

[0002] As is well known, with the rapid development of data centers and intelligent equipment rooms, the modularity, scalability, and ease of maintenance of rack power distribution units (PDUs), as core power distribution equipment, are increasingly important. Traditional rack PDUs mostly adopt integrated welded or bolted structures, which have the following technical bottlenecks: First, the rigid physical connection between power distribution modules requires specialized tools for installation, resulting in low disassembly and assembly efficiency and making it difficult to meet the rapid deployment needs of modern data centers; second, the fixed structure requires the replacement of the entire PDU unit when expanding functionality, leading to resource waste and increased downtime maintenance costs.

[0003] While current improved PDUs attempt to adopt modular design, they still have key shortcomings: the connection mechanism mostly uses snap-fit ​​or threaded fastening methods. Threaded fastening requires tools to complete the assembly, which is highly complex and lacks a quick unlocking function. During maintenance, adjacent modules need to be disassembled layer by layer, which seriously affects the availability of the equipment. The one-way snap-fit ​​structure is prone to gradual loosening in vibration environments. There is still a lack of a solution that can both ensure stable electrical performance and achieve convenient disassembly and assembly. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a scalable prefabricated modular cabinet PDU device, which has the following advantages:

[0017] This scalable, prefabricated modular cabinet PDU unit, with its assembly blocks, slots, and locking devices, utilizes electrical connectors and slots, along with matching locking mechanisms, to make component connections simple and quick. Users can complete installation or disassembly without additional tools. The wedge-shaped blocks and slots provide strong tensile strength, maintaining a tight connection between components even under vibration or impact. The use of springs ensures that the wedge blocks automatically reset and securely engage in the slots. Because each component adopts a standardized design and the locking device allows for quick unlocking, replacement or repair is convenient when a part malfunctions. Furthermore, intermediate output socket components can be easily added or removed as needed to adjust the capacity and configuration of the PDU system.

[0018] This expandable prefabricated modular cabinet PDU device features an unlocking mechanism. Users simply pull down the pull plate manually, causing the pull rod and wedge block to move downwards together, compressing the spring and disengaging the wedge block from the wedge groove. This releases the restriction on the assembly block, facilitating quick module separation. The limit groove design further enhances the system's reliability. The pull plate is normally fixed by the limit groove and can only move under manual operation, effectively preventing accidental unlocking due to accidental contact or external impact. This avoids safety hazards such as power outages or equipment damage. This structural design ensures operational controllability while significantly improving system stability and safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5An expandable prefabricated modular cabinet PDU device includes an input terminal assembly 1, an intermediate output terminal socket assembly 2, an end output terminal socket assembly 3, and a locking device. One end of the input terminal assembly 1 is equipped with a first mounting lug 4, and one end of the end output terminal socket assembly 3 is equipped with a second mounting lug 5. Both the input terminal assembly 1 and the intermediate output terminal socket assembly 2 have electrical connection slots 6 at their ends away from the first mounting lug 4. Both the intermediate output terminal socket assembly 2 and the end output terminal socket assembly 3 have electrical connectors 7 at their ends away from the electrical connection slots 6. The electrical connectors 7 are electrically connected to the electrical connection slots 6. An assembly assembly is located below each set of electrical connection slots 6. The assembly slot 8 is equipped with the locking device. An assembly block 9 is installed below each set of electrical connectors 7. The assembly block 9 and the assembly slot 8 are locked together by the locking device. In this embodiment, during use, it is first necessary to confirm the required number of input terminal components 1, intermediate output terminal socket components 2, and terminal output terminal socket components 3. These components are all designed with electrical connectors 7 and electrical slots 6 to facilitate their connection. When assembling the PDU as needed, pick up an intermediate output terminal socket component 2 and insert one end of its electrical connector 7 into the electrical slot 6 at the end of the input terminal component 1 furthest from the first lug 4. At this time, the assembly block 9 will enter the assembly slot. Install the components into slot 8, and then use the locking device to automatically and securely lock them together. Repeat this step to add more intermediate output socket assemblies 2 until the required number is reached. The last assembly is the terminal output socket assembly 3, which has a second lug 5 on one end for final fixation and an electrical connector 7 on the other end. Insert this electrical connector 7 into the electrical slot 6 of the last intermediate output socket assembly 2, and lock it again using the locking device. After completing the installation of all components, check that each connection point is safe and reliable, and perform an electrical performance test on the entire PDU system to ensure that power can be smoothly transmitted to each socket. Then, connect the PDU through the... The first mounting bracket 4 and the second mounting bracket 5 are installed inside the rack. This modular design allows users to increase or decrease the number of intermediate output socket components 2 according to actual needs, thereby easily adjusting the capacity and configuration of the PDU system. Due to the design of electrical connectors 7 and electrical slots 6, as well as the matching locking device, the connection between components is simple and quick, greatly reducing the difficulty and time cost of installation. At the same time, if a part has a problem, it can be easily replaced or repaired. The prefabricated modular design means that all components are manufactured according to standard specifications, which not only facilitates transportation and storage, but also effectively utilizes the space inside the rack, maximizing resource utilization.

[0027] Preferably, in this embodiment, the locking device includes a rectangular groove 10, a locking box 11, a movable groove 12, a spring 13, a wedge block 14, a wedge groove 15, and an unlocking device. A rectangular groove 10 is formed below the assembly groove 8, and the locking box 11 is fixedly installed within the rectangular groove 10. The movable groove 12 is formed on the top wall of the locking box 11, and the spring 13 is installed within the movable groove 12. The wedge block 14 is installed at the top of the spring 13. The bottom wall of the assembly block 9 has an opening... The wedge-shaped groove 15 is provided, and the wedge-shaped block 14 is adapted to the wedge-shaped groove 15. The unlocking device is installed on the bottom wall of the locking box 11. The component with the electrical connector 7, such as the intermediate output socket component 2 or the end output socket component 3, is pushed towards another component, such as the input component 1 or another intermediate output socket component 2, so that the electrical connector 7 enters the electrical contact groove 6, and the assembly block 9 slides into the assembly groove 8. At this time, the assembly block 9 will move along the direction of the rectangular groove 10 and gradually approach the wedge. As assembly block 9 continues to penetrate deeper into assembly groove 8, the wedge groove 15 at its bottom aligns with and contacts wedge block 14. Due to the inclined design of the top of wedge block 14 and the pressure of spring 13, wedge block 14 is temporarily pressed down as assembly block 9 advances. Once wedge block 14 is fully inserted into wedge groove 15, spring 13 pushes wedge block 14 upward, causing it to lock into wedge groove 15, completing the locking action. The status of the unlocking device can be observed or manually checked to confirm whether the locking has been successful. If further security is required, the components can be gently pulled to ensure that there is no looseness between them. The design of spring 13 and wedge block 14 enables a fast and reliable locking process that can be completed without additional tools. This not only improves work efficiency but also reduces the possibility of human error. The cooperation between wedge block 14 and wedge groove 15 provides strong tensile strength, maintaining a tight connection between components even in vibration or impact environments, increasing the stability and safety of the system.

[0028] Preferably, in this embodiment, the unlocking device includes a slide groove 16, a pull rod 17, and a pull plate 18. The bottom wall of the locking box 11 has the slide groove 16, and the bottom wall of the wedge block 14 is fitted with the pull rod 17. The bottom end of the pull rod 17 passes through the slide groove 16 and is fitted with the pull plate 18. Under normal conditions, the wedge block 14 is engaged in the wedge groove 15 at the bottom of the assembly block 9 by the action of the spring 13, firmly locking the two PDU modules together. The user only needs to gently press down with their hand... Pull plate 18, through pull rod 17, drives wedge block 14 downward, compressing spring 13, causing wedge block 14 to disengage from wedge groove 15. Once wedge block 14 is completely away from wedge groove 15, the mechanical restriction on assembly block 9 is released. At this time, assembly block 9 can be easily pulled out from assembly groove 8, completing the separation between modules. After releasing, pull plate 18 is no longer under force. Under the action of spring 13's rebound force, wedge block 14 will automatically return to its original position, ready for the next locking operation.

[0029] Preferably, in this embodiment, each locking box 11 has a limiting groove 19 on its bottom wall. The limiting groove 19 is adapted to the pull plate 18. Through the design of the limiting groove 19, it can be ensured that the pull plate 18 can only be limited in the limiting groove 19 in the normal state, avoiding accidental unlocking caused by accidental touch or impact from external objects. It ensures that the unlocking action can only be triggered when the user intentionally does so, reducing the safety hazards caused by accidental unlocking, such as power outages or equipment damage.

[0030] Preferably, in this embodiment, the bottom wall of the pull plate 18 is provided with anti-slip texture. The anti-slip texture increases the friction between the fingers and the surface of the pull plate 18, making it more stable and less likely to slip when the user pulls the pull plate 18.

[0031] Preferably, in this embodiment, guide grooves 20 are provided at both the front and rear ends of the movable groove 12, and guide blocks 21 are installed at both the front and rear ends of the wedge block 14. The guide blocks 21 and the guide grooves 20 are slidably connected. When the wedge block 14 moves, it drives the guide blocks 21 to slide in the guide grooves 20. The design of the guide grooves 20 and the guide blocks 21 can ensure that the wedge block 14 moves only along a predetermined direction, i.e., the vertical direction, avoiding lateral offset or tilting. By restricting the movement path of the wedge block 14, unnecessary displacement due to external vibration or impact during use can be effectively prevented, thereby enhancing the stability of the entire locking mechanism.

[0032] Preferably, in this embodiment, a guide rod 22 is fixedly installed in the guide groove 20, and the guide rod 22 and the guide block 21 are slidably connected. The guide rod 22 further provides a more precise guide path for the guide block 21, ensuring that the guide block 21 moves along a straight line and avoiding any lateral offset or tilt.

[0033] Preferably, in this embodiment, both the guide block 21 and the guide groove 20 are cylindrical. The cylindrical design makes the contact surface of the guide block 21 on the guide rod 22 smaller, thereby reducing friction. Compared with planar sliding, this design can more effectively reduce friction loss and extend the service life of the component.
