Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a copper busbar connection structure for a power module of a smart computing center. Background Technology

[0002] In the power system of an intelligent computing center, the efficient and stable operation of the power modules is crucial. As a key component connecting electrical equipment and transmitting current, the copper busbar's connection structure directly affects the performance of the intelligent computing center's power system, and the connection quality of the internal copper busbars directly relates to the operational stability and safety of the entire system. As a high-current conductor, the copper busbar needs to achieve reliable connections with each functional unit of the power module; therefore, the rationality of its connection method is particularly critical.

[0003] Currently, a step-by-step bolt fixing method is commonly used for connecting copper busbars in power modules such as molded case switches. Specifically, for the three copper busbars (red, yellow, and green) installed on the molded case switch, they are first installed into the corresponding holes on the switch using bolts, but not tightened. Then, the busbars are visually inspected for misalignment; if misalignment is found, it is manually adjusted. After adjustment, multiple sets of vertically arranged copper busbars of the same color (e.g., red busbars) on the molded case switches are connected using corresponding horizontal busbars. After aligning the holes, screws are installed, flat spring washers are fitted, and finally, nuts are installed, completing the installation of subsequent holes in sequence. In addition, other methods such as welding, crimping, and plugging are also used for connecting copper busbars in power modules. Bolt connections are widely used in these scenarios due to their degree of detachability.

[0004] The existing installation and connection methods for copper busbars on molded case switches have several drawbacks. First, the installation process is cumbersome. Three copper busbars of different colors need to be initially installed and loosened with bolts at the switch holes, followed by manual visual inspection to check for misalignment and manual adjustment. When connecting multiple vertical copper busbars, each hole must be aligned and fitted with screws, spring washers, and nuts, requiring repeated steps for each hole. This is time-consuming and labor-intensive in scenarios involving multiple molded case switches, impacting the installation progress. Second, installation accuracy relies heavily on manual labor and suffers from poor stability. Checking for misalignment of vertical copper busbars relies on visual judgment, making the adjustment process subjective and difficult to guarantee, potentially leading to uneven stress on the busbars. Furthermore, when connecting horizontal copper busbars, initial positioning deviations during bolt tightening may cause deformation, affecting conductivity and connection stability. Therefore, a new copper busbar connection structure for intelligent computing center power modules needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model embodiment provides a copper busbar connection structure for a power module in a smart computing center, which solves the problems of cumbersome copper busbar installation process, time-consuming multiple repetitive operations, reliance on manual installation accuracy, easy positioning deviation, uneven stress and deformation of the copper busbar.

[0007] This utility model embodiment adopts the following technical solution: a copper busbar connection structure for a power module in a smart computing center. It mainly includes a control cabinet, inside which are neatly arranged molded case circuit breakers. Each molded case circuit breaker is equipped with multiple sets of mounting slots, and multiple sets of positioning components are installed in the mounting slots. The positioning components have through slots adapted to the cross-sectional dimensions of the copper busbars. Vertical copper busbars are fixed in the mounting slots. Electrical control components are installed on the inner wall of the control cabinet, and multiple sets of horizontal copper busbars are installed on the electrical control components. A connection assembly is disposed on the vertical copper busbars. The connection assembly includes a hollow mounting cover installed on the vertical copper busbars. Two sets of clamping arms for fixing the horizontal copper busbars are slidably inserted on both sides of the mounting cover. Two sets of vertically arranged disc springs are connected between the two sets of clamping arms. A locking assembly is disposed on the bottom surface of the mounting cover, and the locking assembly is used to further maintain the connection stability between the horizontal and vertical copper busbars.

[0008] Furthermore, the vertical copper busbar has holes corresponding to the connection positions of the horizontal copper busbar, and the horizontal copper busbar has protrusions integrally formed at the holes corresponding to the vertical copper busbar holes. The protrusions are made of the same material as the copper busbars and make metal contact with the holes.

[0009] Furthermore, one end of each of the two sets of clamping arms that extends into the mounting cover is provided with an arc-shaped clamp that contacts the protrusion. A flexible sealing ring is fitted onto the protrusion, and a flexible anti-detachment part is added to the protrusion. The clamping arm is located between the sealing ring and the anti-detachment part, forming a front-to-back constraint structure.

[0010] Furthermore, the inner side of the arc-shaped chuck of the clamping arm is provided with several evenly distributed barb structures, and the surface of the protrusion has embedded micro-textures.

[0011] Furthermore, each of the two sets of clamping arms has a handle integrated at one end extending from the mounting cover.

[0012] Furthermore, the locking assembly includes a mounting bracket installed on the bottom surface of the mounting cover, the mounting bracket being arranged to fit the bottom surface of the mounting cover, a nut being welded onto the mounting bracket, the nut being coaxial with the mounting bracket, a locking shaft being threaded through the mounting bracket, and the outer surface of the locking shaft being machined with threads adapted to the nut;

[0013] A locking plate is installed at one end of the locking shaft. The locking plate has a plate-like structure. A hook part is movably connected to the locking plate through a rotating shaft. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the side of the locking plate, and the other end is connected to the hook part. Two sets of hook parts are provided on the hook part. The hook parts are symmetrically distributed. A lifting ring is installed on the bottom surface of the clamping arm. A sliding groove is opened on the bottom surface of the mounting cover.

[0014] Furthermore, one end of the lock shaft has a handle that is easy for manual gripping.

[0015] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0016] A copper busbar connection structure for a power module in a smart computing center is disclosed. The vertical copper busbar is guided by a through-slot in the positioning component, replacing manual support and visual adjustment. A torque wrench is used for fixation, preventing misalignment and reducing repetitive operations in scenarios with multiple molded case circuit breakers, thus improving installation efficiency. The clamping arms of the connecting components work with disc springs to achieve rapid connection between the horizontal and vertical copper busbars. The mechanical engagement of barbs and raised patterns, along with the sealing ring and anti-dislodgement features, enhances connection stability and prevents displacement due to vibration. A locking component provides secondary reinforcement, forming a double protection with the disc springs to prevent loosening of the clamping arms. This solves the problem of copper busbar deformation caused by positioning deviations in traditional bolt connections, ensuring stable conductivity and improving the operational reliability of power modules in smart computing centers.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-4 As shown in the figure, the copper busbar connection structure of the power module of the intelligent computing center provided by this utility model embodiment includes a control cabinet 1, and a molded case circuit breaker 11 arranged in a neat manner is provided inside the control cabinet 1. The molded case circuit breaker 11 is fixed on the mounting beam of the control cabinet 1 at a preset interval to form an orderly power distribution unit. Each molded case circuit breaker 11 is equipped with multiple sets of mounting slots 12. The inner side wall of the mounting slot 12 is provided with reinforcing ribs to improve the structural strength. Multiple sets of positioning parts 13 are installed in each set of mounting slots 12. The positioning parts 13 are made of insulating material and are fixed to the mounting slots 12. A through slot (not shown in the figure) is opened on the top of the positioning part 13. The through slot is adapted to the cross-sectional size of the vertical copper busbar 16. The slot wall is also provided with a wear-resistant coating, which can help the vertical copper busbar 16 to be accurately guided during installation and reduce friction loss during the insertion process.

[0028] Three sets of vertical copper busbars 16 (corresponding to red, yellow, and green, respectively, corresponding to phases A, B, and C of a three-phase circuit) are fixedly installed in the mounting slot 12 by bolts 14. During installation, the vertical copper busbars 16 are first inserted into the mounting slot 12 through the through slot. The two side walls of the through slot can effectively limit the vertical copper busbars 16, preventing them from shifting left or right or tilting forward or backward during the tightening of the bolts 14. Then, the bolts 14 are tightened with a torque wrench to complete the fixation. This effectively avoids the problem of the vertical copper busbars 16 becoming skewed during tightening due to manual support of the copper busbars in traditional installation.

[0029] Meanwhile, the inner wall of the control cabinet 1 is equipped with an integrated electrical control component 15. This electrical control component 15 is fixed to the vertical beam of the control cabinet 1 via guide rails, ensuring the consistency and stability of the installation. Multiple sets of horizontal copper busbars 17 are installed on the electrical control component 15. The horizontal copper busbars 17 are adapted to the electrical control component 15 through a connecting assembly 2. The connecting assembly 2 includes a semi-enclosed mounting cover 21 fixedly installed on the vertical copper busbar 16. The mounting cover 21 has a hollow structure, and two sets of clamping arms 22 are slidably inserted on both sides to achieve clamping action on subsequent components.

[0030] Furthermore, holes (not shown in the figure) are provided on the vertical copper busbar 16 corresponding to the connection position of the horizontal copper busbar 17, and a protrusion 171 is integrally formed on the horizontal copper busbar 17 corresponding to the hole of the vertical copper busbar 16. The material of the protrusion 171 is the same as that of the copper busbar, and it makes metal contact with the hole to ensure the continuous and stable conductive path of power transmission, and to provide basic electrical connection guarantee for the reliable operation of the power module.

[0031] Furthermore, an arc-shaped chuck (not shown in the figure) is provided at one end of the two sets of clamping arms 22 that extends into the mounting cover 21 and contacts the protrusion 171. However, in combination with the structural logic, the arc-shaped chuck is designed to adapt to the shape of the protrusion 171 to achieve stable clamping. Moreover, the arc-shaped chuck is made of insulating materials such as reinforced nylon and only undertakes the task of mechanical fixation. This avoids the impact of the conductivity of the clamping parts on the original power transmission path of the copper busbar, thus controlling the boundary between functionality and conductivity.

[0032] A flexible sealing ring 172 is fitted onto the protrusion 171. When the protrusion 171 passes through the hole, the sealing ring 172, due to its own elasticity, will adhere tightly to the side of the vertical copper busbar 16 away from the horizontal copper busbar 17, effectively preventing the intrusion of external dust, moisture, etc., and improving the environmental adaptability of the connection. At the same time, a flexible anti-detachment part 173 is also added to the protrusion 171. The clamping arm 22 is located between the sealing ring 172 and the anti-detachment part 173, forming a front and rear constraint structure. The anti-detachment part 173 can prevent the clamping arm 22 and the protrusion 171 from easily detaching under vibration and other working conditions, enhancing the reliability of the connection.

[0033] Furthermore, two sets of symmetrically arranged disc springs 23 are connected between the two sets of clamping arms 22 (see reference). Figure 4 ), utilizing its unique multi-piece stacked structure, continuously outputs stable locking force. Even after long-term use, the clamping arm 22 may undergo slight deformation, but it can still maintain sufficient clamping force to ensure stable connection. This allows the connection between the horizontal and vertical copper busbars 16 to remain stable under various working conditions. In the default state, the two sets of clamping arms 22 are brought together by the elastic action of the disc spring 23, so that the arc-shaped chuck is tightly attached to the surface of the protrusion 171, forming a stable mechanical clamping foundation.

[0034] To further enhance the connection's vibration resistance and anti-loosening capabilities, this application features a special optimization of the inner side of the arc-shaped chuck of the clamping arm 22, adding several evenly distributed barb structures. Correspondingly, micro-textures (which can be understood as engagement points adapted to the barbs) are machined and embedded on the surface of the protrusion 171. When the arc-shaped chuck grips the protrusion 171, the barbs contact the surface of the protrusion 171, embedding themselves into the micro-textures to form a mechanical engagement effect. Combined with the original anti-slip texture of the arc-shaped chuck, this significantly increases the friction, effectively preventing the protrusion 171 from axial displacement due to vibration during equipment operation, thus making the connection between the horizontal copper busbar 17 and the vertical copper busbar 16 more stable.

[0035] Furthermore, each of the two sets of clamping arms 22 extending from the mounting cover 21 has an integrated handle 24. The handle 24 is designed for easy gripping and is integrally molded with the clamping arm 22. The material used is high-strength engineering plastic or metal (if metal, insulation treatment is required). When connecting the horizontal copper busbar 17 and the vertical copper busbar 16, the operator can easily push the clamping arms 22 to both sides using the handle 24. The handle 24 overcomes the force of the disc spring 23, quickly allowing the clamping arms 22 to open sufficiently, so that the protrusion 171 of the horizontal copper busbar 17 can be smoothly aligned and inserted into the hole of the vertical copper busbar 16. This simplifies the connection operation steps, reduces the difficulty of manual operation, and improves operational efficiency and convenience, especially in scenarios where multiple sets of copper busbars are connected in batches.

[0036] To further maintain the connection stability between the horizontal copper busbar 17 and the vertical copper busbar 16, such as Figures 3-4 As shown, a locking assembly 3 is provided on the bottom surface of the mounting cover 21. The locking assembly 3 includes a mounting bracket 31 fixedly mounted on the bottom surface of the mounting cover 21, and the mounting bracket 31 is arranged to fit the bottom surface of the mounting cover 21. A nut 32 is welded to the side of the mounting bracket 31 near the vertical copper busbar 16. The nut 32 and the mounting bracket 31 are coaxial to ensure the smoothness of subsequent threaded connection. At the same time, a locking shaft 33 is threaded through the mounting bracket 31. One end of the locking shaft 33 has a handle 35 for easy manual gripping. The outer surface of the locking shaft 33 is machined with threads that are adapted to the nut 32. The two are threadedly connected to form the adjustment core of the locking assembly 3.

[0037] A locking plate 34 is fixedly installed at one end of the locking shaft 33. The locking plate 34 has a sheet-like structure, and a hook part 36 is movably connected to the locking plate 34 via a rotating shaft. A torsion spring 37 is sleeved on the rotating shaft. One end of the torsion spring 37 is connected to the side of the locking plate 34, and the other end is connected to the hook part 36. Under the elastic action of the torsion spring 37, the hook part 36 is initially in a vertical state. Two sets of hook parts 38 are provided on the hook part 36. The hook parts 38 are symmetrically distributed. At the same time, a lifting ring 39 is fixedly installed on the bottom surface of the clamping arm 22. Meanwhile, a sliding groove (not shown in the figure) is opened on the bottom surface of the mounting cover 21 to provide a space for the clamping arm 22 to move, so as to ensure that the clamping arm 22 is not interfered with by the mounting cover 21 during the pushing and resetting process.

[0038] After the two sets of clamping arms 22 have completed the initial locking of the protrusion 171 (i.e., the arc-shaped clamps hold the protrusion 171), the reinforcement process of the locking assembly 3 begins. The operator first rotates the hook part 36 towards the mounting frame 31 to overcome the initial elastic force of the torsion spring 37, allowing the hook part 36 to change from a vertical state to an operable angle. Then, the operator holds and rotates the locking shaft 33, and through the threaded transmission between the locking shaft 33 and the nut 32, the locking plate 34 is gradually rotated to a vertical state (during this process, the locking shaft 33 moves axially along the mounting frame 31, causing the locking plate 34 to adjust its position synchronously). After that, the hook part 36 is loosened, and under the action of the rebound force of the torsion spring 37, the hook part 36 quickly returns to a vertical state, and the hook part 38 on it is fastened to the lifting ring 39 on the bottom surface of the clamping arm 22.

[0039] This mechanical locking action fixes the position of the clamping arm 22 again, forming a double constraint of disc spring 23 and locking component 3. Even if the equipment vibrates during long-term operation, the clamping arm 22 will not easily open, which greatly improves the stability of the connection between the horizontal copper busbar 17 and the vertical copper busbar 16 from the mechanical structure level.

[0040] Working principle: During the assembly of the power module, the operator needs to align the red, yellow, and green vertical copper busbars 16 with the A, B, and C phases of the three-phase circuit, respectively, and align them with the positioning pieces 13 in each set of mounting slots 12 on the molded case circuit breaker 11. The through slot at the top of the positioning piece 13 matches the cross-sectional dimensions of the vertical copper busbar 16. The wear-resistant coating on the slot wall reduces frictional resistance during insertion, while the side walls provide rigid constraints on the copper busbar. After the vertical copper busbar 16 is inserted into the mounting slot 12 along the through slot, the through slot restricts its offset in the left-right and front-back directions. At this time, tightening the bolts 14 with a torque wrench will securely fix the copper busbar in the mounting slot 12. This process replaces manual support with mechanical guidance, avoiding the problem of copper busbar skewing during tightening caused by inaccurate manual positioning in traditional installation, and laying the spatial foundation for the subsequent connection of the horizontal copper busbars 17.

[0041] Before the horizontal copper busbar 17 and the vertical copper busbar 16 are connected, the two sets of clamping arms 22 are in a naturally close state under the action of the disc springs 23 symmetrically distributed vertically, and the arc-shaped chucks are in close contact with the surface of the protrusion 171. The operator pushes the clamping arms 22 to both sides by holding the handle 24, overcoming the elastic force of the disc springs 23 and opening the arc-shaped chucks. At this time, the protrusion 171 of the horizontal copper busbar 17 can be smoothly inserted into the hole of the vertical copper busbar 16. The metal contact between the protrusion 171 and the hole forms a conductive path, and the surface tin plating treatment enhances the conductivity. At the same time, the sealing ring 172 on the protrusion 171 is in close contact with the back of the vertical copper busbar 16 to achieve a seal, and the anti-disengagement part 173 limits the clamping arms 22. After the handle 24 is released, the rebound force of the disc spring 23 drives the clamping arm 22 to return to its original position. The barbs on the inner side of the arc-shaped chuck embed into the tiny textures on the surface of the protrusion 171, forming a mechanical engagement with the anti-slip texture. Through the dual action of friction and elastic clamping force, the initial stable connection of the horizontal and vertical copper busbars 16 is achieved.

[0042] To cope with complex working conditions such as long-term vibration, the locking assembly 3 provides secondary reinforcement to the connection. After the clamping arm 22 completes the initial locking of the protrusion 171, the operator rotates the hook part 36 towards the mounting bracket 31, overcoming the elastic force of the torsion spring 37 to deviate it from the vertical position. Then, the locking shaft 33 is rotated, and the locking plate 34 is rotated to the vertical position through the threaded transmission with the nut 32. After releasing the hook part 36, the rebound force of the torsion spring 37 quickly returns it to its original position, and the two sets of hook parts 38 engage with the lifting ring 39 on the bottom surface of the clamping arm 22. At this time, the threaded connection of the locking shaft 33 and the elastic constraint of the torsion spring 37 work together to completely lock the position of the clamping arm 22, forming a double fixation with the disc spring 23 to ensure the connection stability of the horizontal and vertical copper busbars 16.
