Currently, the assembly design of existing converter CP modules has many shortcomings. They mostly adopt a discrete structural layout, lack clear installation zones for each functional component, and are prone to spatial interference problems during assembly. At the same time, the connection of each electrical component often requires on-site, piece-by-piece debugging and alignment, lacking a unified standardized docking structure. The assembly process is cumbersome, highly dependent on the professional skills of operators, and has low assembly efficiency. In addition, the existing structure lacks effective error prevention and positioning design, which easily leads to assembly misalignment, resulting in increased parasitic inductance inside the module, unreliable electrical connections, and even damage to components, making it difficult to meet the needs of large-scale, high-efficiency industrial production.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0030] Reference Figures 1-12 This embodiment provides an easy-to-assemble converter CP module, which includes a base assembly 100. The power module 200 is precisely fixed to the base assembly 100 by positioning and fastening, providing core power conversion support for the entire module.

[0031] The composite busbar 300 is an integrated pre-assembled structure. Its two ends are precisely connected to the power module 200 and the capacitor assembly 400, respectively, to complete the transmission and filtering of DC power. The capacitor assembly 400 is firmly fixed to the base assembly 100 through the bottom positioning structure, and the top terminal of the capacitor assembly 400 can also provide limiting support for the installation end of the composite busbar 300. No additional support components are required, reducing assembly parts and operation steps.

[0032] The control drive module 500 and the power module 200 are connected in a standardized manner at one end near the control drive module 500 and the composite busbar 300 to complete the transmission of control signals and DC power input. The other end is quickly locked with the copper busbar assembly 600 to complete the output of AC power. The overall power and signal connection path is clear. During assembly, it can be operated step by step according to the function side to avoid wiring confusion and misalignment.

[0033] Specifically, the base assembly 100 includes a first base 101 and a second base 102 fixed on top of it. The second base 102 is an integrated partition structure that can precisely separate the top area of ​​the first base 101. A first placement area 101a and a second placement area 101b with uniform specifications and precise positioning are formed on both sides of the second base 102. This partition design delineates dedicated assembly areas for the capacitor assembly 400 and the copper busbar assembly 600, avoiding spatial interference during component installation from a structural perspective, and achieving the assembly effect of "partition positioning, accurate placement".

[0034] The second base 102 is also fixedly connected to a control motherboard assembly 102a. The control motherboard assembly 102a serves as the control hub of the entire converter CP module. It adopts a modular pre-assembly design, which facilitates rapid assembly and reduces debugging difficulty. Its core is an integrated control motherboard base plate, which integrates four core functional modules: a central processing unit, a PWM signal generation module, a fault detection module, and a power management module.

[0035] The power module 200 is positioned between the control motherboard assembly 102a and the second base 102. The sandwich-like installation space formed by the two provides a stable bearing foundation for the power module 200 and maintains a reasonable electrical clearance between the control motherboard assembly 102a and the power module 200. During assembly, the power module 200 can be embedded into the preset space and tightened simultaneously to achieve mechanical fixation and electrical alignment without the need for repeated position adjustments.

[0036] The capacitor assembly 400 and the copper busbar assembly 600 are fixed in the first installation area 101a and the second installation area 101b respectively by positioning and plugging and bolt locking. Relying on the partition positioning feature of the base assembly 100, the two can be initially positioned at one time, and only a few tightening operations are needed to complete the installation, which greatly shortens the assembly time.

[0037] Furthermore, the copper busbar assembly 600 includes at least two symmetrically arranged connection busbar groups 601. Each connection busbar group 601 includes a main copper busbar 601a and a support column 601b fixed at its bottom. The bottom end of the support column 601b is fixedly connected to the first base 101. Through the standardized height design of the support column 601b, the main copper busbar 601a is always kept horizontal, and no additional leveling is required during assembly. Several sets of connecting ears 601c are fixedly fixed at equal intervals on the main copper busbar 601a. ​​The holes of the connecting ears 601c are precisely matched with the AC side connection end of the power module 200. The main copper busbars 601a are fixedly connected to each other through a docking strip 602. The docking strip 602 and the main copper busbar 601a have a standardized docking structure, which can realize the synchronous splicing of multiple sets of main copper busbars 601a, simplifying the overall assembly process of the copper busbar assembly 600.

[0038] The composite busbar 300 includes a first insulating plate 301, a first connecting bar 302, a first insulating layer 303, a second connecting bar 304, and a second insulating plate 305 stacked together. This five-layer structure only needs to be stacked and spliced ​​one by one, and can be directly installed as a whole, which reduces assembly steps and operational errors from the source.

[0039] The first insulating plate 301, the first insulating layer 303, and the second insulating plate 305 work together to fully cover the first connecting bar 302 and the second connecting bar 304, forming an all-round, dead-angle-free insulating protection structure. No additional adhesive or insulating parts are required during assembly, which simplifies the operation and ensures the consistency and reliability of the insulating protection.

[0040] The first insulating plate 301, the first insulating layer 303, and the second insulating plate 305 are all integrated bending structures, and each includes a first bending segment A1, a second bending segment A2, and a third bending segment A3. The first bending segment A1 and the third bending segment A3 are fixed at a preset angle to the opposite sides of the two ends of the second bending segment A2, and the first bending segment A1 and the third bending segment A3 are both arranged parallel to the first base 101. This bending structure is highly compatible with the internal spatial layout of the converter CP module, and can be directly embedded into the preset installation path during assembly without adjusting the angle and position, achieving a "one-time" assembly effect.

[0041] Several sets of positioning holes A11 are equidistantly provided on the first bending section A1. The positioning holes A11 are precisely matched with the terminals of the capacitor assembly 400. During assembly, the positioning holes A11 guide the precise alignment of the composite busbar 300 and the capacitor assembly 400, avoiding rework caused by hole misalignment.

[0042] The first connecting busbar 302 is adapted to the insulation structure and includes a first copper busbar section B1, a second copper busbar section B2, and a third copper busbar section B3. The first copper busbar section B1, the second copper busbar section B2, and the third copper busbar section B3 are respectively covered within the first bending section A1, the second bending section A2, and the third bending section A3, forming a precise fit with the insulation structure. No additional adjustment of the copper busbar position is required during assembly.

[0043] The second connecting busbar includes a fourth copper busbar segment B4, a fifth copper busbar segment B5, and a sixth copper busbar segment B6. The fourth copper busbar segment B4, the fifth copper busbar segment B5, and the sixth copper busbar segment B6 respectively cover the first bending segment A1, the second bending segment A2, and the third bending segment A3, forming a double-layer copper busbar power transmission structure together with the first connecting busbar 302.

[0044] The first insulating layer 303 is sandwiched between the first connecting busbar 302 and the second connecting busbar 304 to achieve reliable electrical isolation between the two. Its integrated molding structure has a high degree of fit with the two sets of copper busbars. There is no need to adjust the position of the insulating layer separately during assembly, ensuring the reliability of insulation between the high and low voltage copper busbars.

[0045] A first terminal B11 is fixed on the edge of the first copper busbar section B1 away from the second copper busbar section B2. A first through hole B12 is also arrayed on the first copper busbar section B1. A second through hole B13 is also correspondingly opened on one side of the first through hole B12. The double through hole structure forms a double positioning reference, which further improves the docking accuracy with the capacitor assembly 400.

[0046] Several sets of second terminals B31 are fixed on the edge array of the third copper busbar section B3 away from the second copper busbar section B2. The second terminals B31 are standardized connection structures with strong adaptability and can be quickly connected to the power module 200 and the control drive module 500.

[0047] A third terminal B41 is fixed on the edge of the fourth copper busbar segment B4 away from the fifth copper busbar segment B5. A third through hole B42 is also arrayed on the fourth copper busbar segment B4. A groove protrusion B43 is correspondingly provided on the fourth copper busbar segment B4 on one side of the third through hole B42. A fourth through hole B44 is also provided in the middle of the groove protrusion B43. The groove protrusion B43 and the first through hole B12 form a fitting positioning structure, which can achieve precise alignment of the first connecting busbar 302 and the second connecting busbar 304 during assembly without additional calibration.

[0048] Several sets of fourth terminals B61 are fixed on the edge of the sixth copper busbar section B6 away from the fifth copper busbar section B5. The fourth terminals B61 and the second terminals B31 are symmetrically arranged to form a standardized connection and mating structure.

[0049] Among them, the groove protrusion B43 is adapted to be embedded in the middle of the first through hole B12 to form an interlocking anti-foolproof positioning structure, which structurally prevents the first connecting bar 302 and the second connecting bar 304 from being misaligned during assembly. The second through hole B13 is adapted to be located in the middle of the third through hole B42 to further enhance the alignment effect of the two sets of copper bars and improve the assembly accuracy. The second terminal B31 and the fourth terminal B61 form a symmetrically arranged connecting pin C. The connecting pin C is an integrated molded standardized quick-connect structure, which can simultaneously realize docking with the power module 200, greatly reducing wiring operations and assembly time.

[0050] The capacitor assembly 400 includes a capacitor body 401, terminals 402, and positioning posts 403. The terminals 402 are symmetrically connected to the top of the capacitor body 401 and make precise contact with the first copper busbar section B1 and the fourth copper busbar section B4 respectively, completing the connection of power transmission and filtering. The positioning posts 403 are fixed to the middle of the bottom end of the capacitor body 401 and are fixedly inserted into the preset positioning structure in the first placement area 101a. During assembly, the positioning posts 403 only need to be inserted into the preset positioning structure to complete the initial positioning of the capacitor assembly 400. Only a few tightening operations are needed to complete the final fixation, achieving the assembly effect of "insertion positioning and quick tightening".

[0051] Several control drive modules 500 and power modules 200 are provided in a one-to-one correspondence. Each control drive module 500 is symmetrically fixed with a first docking terminal 501 and a second docking terminal 502. The first docking terminal 501 and the second docking terminal 502 are respectively fixedly connected to the second terminal B31 and the fourth terminal B61 of the connecting pin C, so as to realize the accurate transmission of control signals to the power module 200. The two have a standardized docking structure, and no complicated debugging is required during assembly to achieve quick connection.

[0052] The power module 200 includes a power device 201 and an isolation cover plate 202 fixed on its top. The power device 201 has a first power terminal 201a and a second power terminal 201b symmetrically fixed on both sides of the connection end. The first power terminal 201a is fixedly connected to the second terminal B31 and the fourth terminal B61 of the connection pin C to complete the input of DC power and control signal. The second power terminal 201b is fixedly connected to the connection ear 601c fixed at equal distance on the main copper busbar 601a to complete the output of AC power. Both are standardized quick-connect structures, which greatly improves assembly efficiency.

[0053] The top edge of the power device 201 is also connected to an interface pin 201c. A corresponding clearance positioning hole 202a is provided on the isolation cover 202. The interface pin 201c passes through the clearance positioning hole 202a. The clearance positioning hole 202a has both clearance and positioning functions. It can avoid mechanical interference between the isolation cover 202 and the interface pin 201c, and can achieve precise alignment between the isolation cover 202 and the power device 201 through the cooperation of the pin and the clearance hole. No additional positioning structure is required, which further simplifies the assembly steps.

[0054] To better utilize the aforementioned easy-to-assemble converter CP module, this embodiment also provides an easy-to-assemble converter CP module installation method, which is applied to the aforementioned easy-to-assemble converter CP module and includes the following steps: First, the second base 102 is fixed to the preset mounting position on the top of the first base 101 by means of positioning pins and bolts to ensure precise alignment between the two. Then, the control motherboard assembly 102a is fitted and fastened to the positioning pins on the second base 102 through positioning holes, thus completing the overall assembly of the base assembly 100 and providing a unified benchmark for the subsequent installation of each component.

[0055] Next, the power module 200 is embedded in the interlayer mounting space between the control motherboard assembly 102a and the second base 102, and the power module 200 is fixed on the base assembly 100 by bolts, so that the power module 200 and the control motherboard assembly 102a maintain a preset electrical clearance.

[0056] Then, the capacitor assembly 400 is precisely inserted into the preset positioning hole in the first placement area 101a through the bottom positioning post 403, and then the capacitor assembly 400 is fastened with bolts; at the same time, the support post 601b of the copper busbar assembly 600 is fixedly connected to the first base 101 in the second placement area 101b, so that the main copper busbar 601a is kept horizontal, and then the main copper busbars 601a are fixedly connected through the docking post 602 to complete the assembly of the copper busbar assembly 600.

[0057] Then, one end of the integrated pre-assembled composite busbar 300 is precisely connected to the terminal 402 of the capacitor assembly 400 through the positioning hole A11, and the other end is connected to the first power terminal 201a of the power module 200, so that the top of the capacitor assembly 400 forms a stable limiting support for the mounting end of the composite busbar 300.

[0058] Finally, the first docking terminal 501 and the second docking terminal 502 of each control drive module 500 are precisely docked and fixed to the second terminal B31 and the fourth terminal B61 on the connecting pin C of the composite busbar 300, respectively. Then, the second power terminal 201b of the power module 200 is fixedly connected to the connecting ear 601c of the copper busbar assembly 600 one by one, thus completing the overall assembly of the converter CP module.

[0059] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
