Description

Technical Field

[0001] This utility model relates to the field of power transmission accessories technology, and in particular to a busbar trunking with an adaptable flange structure. Background Technology

[0002] The flange structure of the busbar trunking serves as a "bridge" or "transition plate" to ensure a tight and secure connection between the busbar trunking and the equipment. It solves the problem of incompatibility between the standard busbar trunking interface and the equipment interface, allowing two different types of electrical equipment to be safely and reliably connected.

[0003] The existing flange structures on busbar trunking are generally set up at uniform intervals, which can only match the connection of equipment with corresponding settings. It is very likely that the flange position will not match the interface of the equipment to be connected, resulting in the need to use an additional long and curved "transition busbar" for connection, which is both troublesome and costly.

[0004] Therefore, there is an urgent need for a bus trunking system with an adaptable flange structure to solve the above-mentioned technical defects. Summary of the Invention

[0005] The purpose of this utility model is to provide a busbar trunking with an adaptable flange structure. This busbar trunking with an adaptable flange structure can flexibly adapt to different spacing and position requirements of equipment interfaces, and has excellent versatility and adaptability to cope with various complex installation environments, thereby improving engineering efficiency and economy.

[0006] To achieve the above objectives, this utility model provides a busbar trunking with an adaptable flange structure, the specific implementation of which is as follows:

[0007] A busbar trunking with an adaptable flange structure includes a busbar trunking body, a connecting housing on the side wall of the busbar trunking body, an installation cavity inside the connecting housing, and the opposite side walls of the connecting housing and the busbar trunking are both open. The side plates on both sides of the busbar trunking body are sealed to both sides of the connecting housing, so that the installation cavity is connected to the inside of the busbar trunking.

[0008] Each copper busbar located within the main body of the busbar trunking extends into the mounting cavity. The outer wall of the connecting housing is provided with several connecting flanges, and the end of each connecting flange extends into the mounting cavity to connect to different copper busbars. The distance between any two adjacent connecting flanges may be the same or different.

[0009] This utility model discloses a busbar trunking system with an adaptable flange structure. Compared to existing technologies, it creates a protected extended connection space that is connected to the busbar trunking body by sealing the connecting housing with the side walls on both sides of the busbar trunking body and making the mounting cavity open to the inside of the busbar trunking. This allows all copper busbar ends to extend directly and safely into this space, providing a centralized access point for external connection flanges. It fundamentally breaks the limitation that traditional flanges must be fixed in a specific position on the busbar trunking housing, allowing the spacing of multiple connection flanges to be flexibly set to be the same or different according to equipment interface requirements, perfectly achieving the core objectives of flexible adaptation, improved versatility, and adaptability.

[0010] In some embodiments, one end of each copper busbar extends outside the busbar trough, and the other end is provided with a connecting section in the shape of an "L" that is fixedly connected to the connecting flange.

[0011] The "L"-shaped connecting section at the end of the copper busbar provides a stable and easy-to-operate connection interface, increases the contact area with the connecting flange, making the connection more robust. At the same time, its bending shape facilitates alignment and installation within the mounting cavity, simplifies the assembly process, and ensures the reliability of the connection.

[0012] In some embodiments, the connecting segment and the copper busbar are integrally formed.

[0013] By integrating the connecting section and the copper busbar into a single piece, the risks of increased contact resistance, overheating, or loosening that may result from secondary connection methods such as bolts or welding are avoided. This design provides better mechanical strength and electrical continuity, thereby improving the overall safety and service life of the product.

[0014] In some embodiments, the sidewall of the connecting housing is provided with a plurality of first through slots corresponding to the connecting segments, and the end of the connecting flange extends through the first through slots into the mounting cavity.

[0015] By opening a first through slot on the side wall of the connecting housing corresponding to the internal connecting section, a precise positioning channel is provided for the access of the connecting flange, ensuring that each connecting flange can be accurately guided to the predetermined position and reliably connected to the "L"-shaped connecting section of the target copper busbar, thus ensuring the regularity of the structure and the accuracy of the connection.

[0016] In some embodiments, a second through groove is provided on the outer wall of the connecting housing to conduct the mounting cavity, and at least one connecting segment is provided within the diameter range of each third through groove. A sealing plate is fixed at each second through groove, and at least one first through groove is provided on each sealing plate.

[0017] The second through groove and the sealing plate with the first through groove together form a modular position adjustment unit, which allows for flexible selection of the final outlet position of the flange on the large outer surface of the connecting housing. By installing the sealing plate with the first through groove pre-cut on the third through groove at different positions, the flange position can be continuously adjusted. The sealing plate with different settings of the first through groove can be replaced to adapt to the connection of equipment in different connection positions. At the same time, the sealing plate ensures the integrity of the protection level of the connecting housing after the position is adjusted, which is the key to achieving high adaptability without sacrificing safety.

[0018] In some embodiments, each of the copper busbars and connecting segments has a fixing member at the top of the connection point, and the two sides of the fixing member are fixedly connected to the two opposing inner walls of the busbar groove to press the copper busbar located below the fixing member.

[0019] By installing fasteners at the top of the connection between the copper busbar and the connecting section, and fixing both sides of the fasteners to the inner wall of the busbar trough, the copper busbar can be effectively compressed and anchored. Especially for the "L" shaped connecting section, it can resist the warping force and torque generated at the connection point due to frequent insertion and removal or vibration, greatly enhancing the mechanical stability and long-term reliability of the connection point and preventing the connection from loosening.

[0020] In some embodiments, the outer peripheral wall of each copper busbar is fitted with a first insulating sleeve, and the portion of the copper busbar extending outside the busbar trough and the portion of the copper busbar connecting to the connecting flange are exposed outside the first insulating sleeve.

[0021] By installing a first insulating sleeve on the copper busbar and exposing it at the connection point, the necessary electrical connection points are precisely exposed while ensuring safe insulation inside the busbar trunking and the connecting housing. This effectively prevents phase-to-phase or phase-to-ground short circuits and greatly improves the electrical safety performance of the product.

[0022] In some embodiments, a second insulating sleeve is fitted on the outer peripheral wall of each connecting flange, and the portion of the connecting flange extending outside the connecting housing and the portion connecting to the copper busbar are exposed outside the second insulating sleeve.

[0023] By installing a second insulating sleeve on the outer periphery of the connecting flange, critical phase-to-phase insulation protection is provided for each independent connecting flange inside the installation cavity. This sleeve covers the entire flange rod after it is connected to the copper busbar, exposing only the necessary connection interfaces at both ends. This effectively prevents phase-to-phase short circuits between flanges or short circuits to the shell ground caused by foreign objects overlapping, condensation, or operational errors in the narrow installation cavity. This greatly enhances the electrical safety and operational reliability of the compact busbar trunking at critical connection points.

[0024] In some embodiments, the connecting flange is welded to the copper busbar or secured with screws.

[0025] The connection stability is improved by welding the connecting flange to the copper busbar or by fixing it with screws.

[0026] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0027] By sealing the connecting housing to the side walls on both sides of the busbar trunking body and making the mounting cavity accessible to the inside of the busbar trunking, a protected extended connection space that runs through the busbar trunking body is created. This allows all copper busbar ends to extend directly and safely into this space, providing a centralized access point for external connection flanges. This fundamentally breaks the traditional limitation that flanges must be fixed to specific positions on the busbar trunking housing, allowing the spacing of multiple connection flanges to be flexibly set to be the same or different according to equipment interface requirements, perfectly achieving the core objectives of flexible adaptation, improved versatility, and adaptability.

[0033] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0034] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0036] like Figure 1-2As shown, the busbar trunking with an adaptable flange structure provided in this embodiment includes a busbar trunking body 100. A connecting housing 200 is provided on the side wall of the busbar trunking body 100. An installation cavity 210 is provided inside the connecting housing 200. The side walls of the connecting housing 200 and the busbar trunking are both open. The side plates 110 on both sides of the busbar trunking body 100 are sealed to both sides of the connecting housing 200, so that the installation cavity 210 is connected to the inside of the busbar trunking.

[0037] Each copper busbar 120 located in the main body 100 of the busbar trunking extends into the mounting cavity 210. The outer wall of the connecting housing 200 is provided with several connecting flanges 300. The end of each connecting flange 300 extends into the mounting cavity 210 to connect to different copper busbars 120. The distance between any two adjacent connecting flanges 300 may be the same or different.

[0038] In some embodiments, one end of each copper busbar 120 extends outside the busbar trough, and the other end is provided with a connecting section 121, which is L-shaped and fixedly connected to the connecting flange 300.

[0039] The “L”-shaped connecting section 121 provided at the end of the copper busbar 120 provides a stable and easy-to-operate connection interface, increases the contact area with the connecting flange 300, making the connection more secure. At the same time, its bending shape facilitates alignment and installation within the mounting cavity 210, simplifies the assembly process, and ensures the reliability of the connection.

[0040] In some embodiments, the connecting segment 121 and the copper busbar 120 are integrally formed.

[0041] By integrally molding the connecting section 121 and the copper busbar 120, the risks of increased contact resistance, overheating, or loosening that may result from secondary connection methods such as bolts or welding are avoided. This provides better mechanical strength and electrical continuity, thereby improving the overall safety and service life of the product.

[0042] In some embodiments, the sidewall of the connecting housing 200 is provided with a plurality of first through grooves 240 corresponding to the connecting segment 121, and the end of the connecting flange 300 extends through the first through grooves 240 into the mounting cavity 210.

[0043] By opening a first through groove 240 on the side wall of the connecting housing 200 corresponding to the internal connecting section 121, a precise positioning channel is provided for the access of the connecting flange 300, ensuring that each connecting flange 300 can be accurately guided to the predetermined position and reliably connected with the "L"-shaped connecting section 121 of the target copper busbar 120, thus ensuring the regularity of the structure and the accuracy of the connection.

[0044] In some embodiments, the outer wall of the connecting housing 200 is provided with a second through groove 220 that connects to the mounting cavity 210. Each third through groove corresponds to at least one connecting segment 121 within its diameter range. A sealing plate 230 is fixed at each second through groove 220. Each sealing plate 230 is provided with at least one first through groove 240.

[0045] The second through groove 220 and the sealing plate 230 with the first through groove 240 together form a modular position adjustment unit, which allows for flexible selection of the final outlet position of the flange on the larger outer surface of the connecting housing 200. By installing the sealing plate 230 with the first through groove 240 pre-cut on the third through groove at different positions, the flange position can be continuously adjusted. The sealing plate 230 with different settings of the first through groove 240 can be replaced to adapt to the connection of equipment in different connection positions. At the same time, the sealing plate 230 ensures the integrity of the protection level of the connecting housing 200 after the position is adjusted, which is the key to achieving high adaptability without sacrificing safety.

[0046] In some embodiments, a fixing member 130 is provided at the top of the connection between each of the copper busbars 120 and the connecting section 121. The two sides of the fixing member 130 are fixedly connected to the two opposing inner walls of the busbar groove to press the copper busbars 120 located below the fixing member 130.

[0047] By setting a fastener 130 at the top of the connection between the copper busbar 120 and the connecting section 121, and fixing its two sides to the inner wall of the busbar trough, the copper busbar 120 can be effectively pressed and anchored. Especially for the "L"-shaped connecting section 121, it can resist the warping force and torque generated at the connection point due to frequent insertion and removal or vibration, greatly enhancing the mechanical stability and long-term reliability of the connection point and preventing the connection from loosening.

[0048] In some embodiments, each copper busbar 120 is fitted with a first insulating sleeve 122 on its outer peripheral wall, and the portion of the copper busbar 120 extending outside the busbar trough and the portion of the copper busbar 120 connected to the connecting flange 300 are exposed outside the first insulating sleeve 122.

[0049] By installing the first insulating sleeve 122 on the copper busbar 120 and exposing it at the connection point, the necessary electrical connection points are precisely exposed while ensuring safe insulation inside the busbar trunking body 100 and the connecting housing 200. This effectively prevents phase-to-phase short circuits or short circuits to ground and greatly improves the electrical safety performance of the product.

[0050] In some embodiments, a second insulating sleeve 310 is fitted on the outer peripheral wall of each connecting flange 300, and the portion of the connecting flange 300 extending outside the connecting housing 200 and the portion connected to the copper busbar 120 is exposed outside the second insulating sleeve 310.

[0051] By installing a second insulating sleeve 310 on the outer periphery of the connecting flange 300, critical phase-to-phase insulation protection is provided for each independent connecting flange 300 inside the mounting cavity 210. This covers the entire flange rod body after it is connected to the copper busbar 120, exposing only the necessary connection interfaces at both ends. This effectively prevents phase-to-phase short circuits between flanges or short circuits to the shell ground caused by foreign object overlap, condensation, or operational errors in the narrow mounting cavity 210. This greatly enhances the electrical safety and operational reliability of the high-density busbar trunking at critical connection points.

[0052] In some embodiments, the connecting flange 300 is welded to the copper busbar 120 or fixed with screws.

[0053] The connection stability between the flange 300 and the copper busbar 120 is improved by welding or fixing them with screws.

[0054] This embodiment provides a busbar trunking system with an adaptable flange structure. Compared to existing technologies, by sealing the connecting housing 200 to the side walls on both sides of the busbar trunking body 100 and making the mounting cavity 210 open to the inside of the busbar trunking, a protected extended connection space is created that is connected to the busbar trunking body. This allows all copper busbars 120 to extend directly and safely into this space, providing a centralized access point for the external connecting flanges 300. This fundamentally breaks the limitation that traditional flanges must be fixed to a specific position on the busbar trunking housing, allowing the spacing of multiple connecting flanges 300 to be flexibly set to be the same or different according to equipment interface requirements, perfectly achieving the core objectives of flexible adaptation, improved versatility, and adaptability.

[0055] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
