Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a modular and quick-assembly lightweight busbar connection structure. Background Technology

[0002] Busbar trunking is a closed metal device composed of copper and aluminum busbars. It is used to distribute large amounts of power to various components in a distributed system. In indoor low-voltage power transmission trunking projects, it has increasingly replaced electrical wires and cables. Connectors are key components of the busbar trunking system, primarily used to achieve electrical connection and mechanical fixation between two sections of busbar trunking, ensuring the safe and reliable transmission of electrical energy. Their main function is to conduct the conductors, such as copper or aluminum busbars, between the two sections of busbar trunking, forming a continuous current path and ensuring efficient power transmission.

[0003] Traditional busbar trunking systems rely on multiple sets of bolts for assembly, which has several drawbacks in practical use. For example, installation and maintenance efficiency is low. Traditional connections require wrenches, screwdrivers, and other tools to tighten multiple sets of bolts sequentially, demanding high installation precision and time-consuming manual alignment. During disassembly and maintenance, bolts must be loosened one by one; if bolts are rusted or jammed, component damage may occur. Furthermore, relying solely on screw threads makes the threads prone to loosening due to long-term vibration, leading to displacement or detachment of the connection, especially in high-frequency vibration environments such as industrial equipment operation, thus presenting certain limitations. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that traditional busbar trunking relies on multiple sets of bolts for splicing, which has many shortcomings in practical use.

[0005] To address the aforementioned technical problems, this application provides a modular, rapid-assembly lightweight busbar trunking connection structure, comprising a busbar trunking body. Connecting plate one and connecting plate two are threaded to both ends of the busbar trunking body, respectively. Connecting plate one and connecting plate two are interlocked. Insert plates one are fixedly installed above and below the middle of ...

[0006] In some embodiments, connector baffles are fixedly installed at both ends of the busbar trunking body, and multiple conductive copper busbars are evenly fixedly installed in the middle of the two connector baffles.

[0007] In some embodiments, screw holes are provided at the four corners above and below the center of the busbar trunking body, and screws are threaded into the center of each of the screw holes.

[0008] In some embodiments, the connecting plate one and the connecting plate two are threaded together by screws and screw holes.

[0009] In some embodiments, positioning posts are fixedly installed at the four corners of one end of the connecting plate one, and positioning holes are opened at the four corners of one end of the connecting plate two. The connecting plate one and the connecting plate two are connected by positioning posts and positioning holes.

[0010] In some embodiments, the T-shaped rod is inserted into the middle of the insertion hole, the actuating groove and the sliding groove are connected, the sliding groove is connected to the insertion hole, the lever is slidably engaged in the middle of the actuating groove, and one end of each of the two springs is fixedly installed on the top of the inner wall of the sliding groove.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. This utility model enables rapid splicing of adjacent busbar trunking bodies. It employs a tool-free design; before splicing, connecting plate one and connecting plate two are simply fixed to both ends of the adjacent busbar trunking bodies with screws. During splicing, connecting plate one of one busbar trunking body is aligned with connecting plate two of the other busbar trunking body, allowing the components to be inserted and automatically locked using spring force. Disassembly is achieved by simply moving a lever to release the lock, significantly shortening construction time. The symmetrical structural design reduces installation errors, and the modular connection supports quick replacement of faulty modules, thereby significantly improving maintenance efficiency.

[0013] 2. In use, this utility model provides a reliable and secure quick connection between adjacent busbar trunking bodies. Precise alignment of the positioning pins and holes, combined with screw thread connections, insert plate connections, and a composite locking mechanism using T-shaped rods and spring clips, forms a multi-layered anti-loosening mechanism that effectively resists vibration and external forces. The springs continuously provide pressure to compensate for wear gaps, and the evenly distributed and tightly fitted conductive copper busbars ensure low electrical resistance and low heat generation, guaranteeing long-term stable operation.

[0020] 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.

[0021] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a modular, quick-assembly, lightweight busbar trunking connection structure, including a busbar trunking body 1. Connecting plate 1 2 and connecting plate 24 are threaded to both ends of the busbar trunking body 1, respectively. Connecting plate 1 2 and connecting plate 24 are interlocked. Insert plates 1 22 are fixedly installed above and below the middle of the middle of the middle of the middle of the two insert plates 1 22. T-shaped rods 23 are fixedly installed on both sides of the middle of one end of the two insert plates 1 22. Insert plates 26 are fixedly installed above and below the middle of the middle of the middle of the middle of the two connecting plates 24. Insert holes 27 are opened on both sides of the middle of one end of the two insert plates 26. Sliding grooves 28 are opened in the middle of the middle of the two insert plates 26. A toggle groove 29 is opened on one side of each of the two insert plates 26. An upper locking plate 30 is slidably engaged in the middle of the sliding groove 28. A lever 32 is fixedly installed on one side of the upper end of the upper locking plate 30, and a lower locking plate 33 is fixedly installed at the lower end of the upper locking plate 30. Springs 31 are fixedly installed on both sides of the middle of the upper end of the upper locking plate 30. The size of the upper locking plate 30 is larger than the width of the bottom of the two T-shaped rods 23 and abuts against it. The size of the lower locking plate 33 is smaller than the gap at the bottom width of the two T-shaped rods 23. The T-shaped rods 23 are inserted into the middle of the insertion hole 27. The actuation groove 29 and the sliding groove 28 are connected. The sliding groove 28 and the insertion hole 27 are connected. The lever 32 is slidably engaged in the middle of the actuation groove 29. One end of each of the two springs 31 is fixedly installed on the top of the inner wall of the sliding groove 28.

[0022] In this embodiment, after the T-shaped rod 23 is inserted into the insertion hole 27, the upper clamping plate 30 presses downwards at the wide part of the T-shaped rod 23 by the elastic force of the spring 31, forming a lateral clamping force to prevent the connection from loosening due to vibration or external force. The insertion of the insertion plate 1 22 and the insertion plate 26, combined with the threaded connection of the connecting plate 1 2 and the connecting plate 2 24, achieves a composite fixation of mechanical connection and clamping, ensuring the structural stability of the busbar trunking body 1 during energized operation. The spring 31 can continuously provide pressure, and even if slight wear occurs after long-term use, the elastic force can compensate for the gap, preventing the connection from loosening and extending the service life of the busbar trunking. For extended lifespan, by moving the lever 32, the upper clamping plate 30 moves up and down within the sliding groove 28, allowing for quick locking and releasing of the T-shaped rod 23. During installation, simply insert the T-shaped rod 23 into the insertion hole 27 and release the lever 32; the spring 31 will automatically lock it in place. During disassembly, move the lever 32 upwards to release the locking state. No additional tools are required, reducing installation and maintenance costs. The sliding grooves 28 and insertion holes 27 of the first insertion plate 22 and the second insertion plate 26 are symmetrically designed, and the dimensions of the T-shaped rod 23 and the insertion hole 27 are matched. During installation, the structure can guide the quick alignment, reducing installation errors and improving construction efficiency.

[0023] Example 2: As Figures 1-3 As shown, connector baffles 12 are fixedly installed at both ends of the busbar trunking body 1. Multiple conductive copper busbars 13 are evenly fixedly installed in the middle of the two connector baffles 12. Screw holes 11 are opened at the four corners above and below the middle of the busbar trunking body 1. Screws 14 are threadedly connected to the middle of the multiple screw holes 11. Connecting plate 1 2 and connecting plate 2 24 are threadedly connected by screws 14 and screw holes 11. Positioning pins 21 are fixedly installed at the four corners of one end of connecting plate 1 2. Positioning holes 25 are opened at the four corners of one end of connecting plate 2 24. Connecting plate 1 2 and connecting plate 2 24 are plugged in by positioning pins 21 and positioning holes 25.

[0024] In this embodiment, the evenly distributed conductive copper busbars 13 on the connector baffle 12 ensure uniform current distribution, reduce local heating caused by uneven conductor distribution, and reduce power loss. As a physical barrier, the connector baffle 12 can prevent foreign objects from contacting the conductive copper busbars 13, reducing the risk of short circuits. At the same time, the baffle material can be made of insulating materials such as engineering plastics, which can further improve insulation performance. The precise fit between the positioning post 21 and the positioning hole 25 provides installation guidance, ensuring quick alignment of the connecting plate 1 2 and the connecting plate 2 24, reducing manual adjustment time. The four-corner positioning design avoids rotation or misalignment during the connection process, ensuring accurate docking of the conductive copper busbars 13, reducing contact resistance. The insertion of the positioning post 21 and the positioning hole 25 can provide initial positioning, facilitating subsequent assembly.

[0025] like Figures 1-5As shown, before splicing the two busbar trunking bodies 1, the corresponding connecting plates 1 and 2 are first fixed by screws 14 and screw holes 11 on the top of the busbar trunking body 1. Then, the end of the busbar trunking body 1 with connecting plate 1 is aligned with the end of the other busbar trunking body 1 with connecting plate 24 and inserted, so that connecting plate 1 and connecting plate 2 are initially aligned by the positioning posts 21 and positioning holes 25 at the four corners, thereby ensuring the positional accuracy of the conductive copper busbar 13. During the insertion process, the T-shaped rod 23 of the insert plate 1 22 will be inserted along the insertion hole 27 of the insert plate 26. At this time, under the action of spring 31, the upper clamping plate 30 will block the movement direction of the T-shaped rod 23 in the insertion hole 27, so that the T-shaped rod 23 cannot touch the bottom of the insertion hole 27, thus preventing the two busbar trunking bodies 1 to be spliced ​​from being connected. At this time, the user can turn the lever. The lever 32 drives the upper clamping plate 30 to move upward along the sliding groove 28, thereby compressing the spring 31. During the process, when the lower clamping plate 33 below the upper clamping plate 30 moves upward to the gap at the wide body of the two T-shaped rods 23, the entire T-shaped rod 23 can completely touch the bottom insertion hole 27, thus completing the splicing of the two busbar trunking bodies 1. Then, the user can release the lever 32. Under the reset push of the spring 31, the upper clamping plate 30 and the lower clamping plate 33 will move downward along the sliding groove 28. At this time, the upper clamping plate 30 is in the initial state and can abut against one side of the wide body of the two T-shaped rods 23, forming a lateral clamping force to prevent the connection from loosening due to vibration or external force. During maintenance or disassembly, simply reverse the lever 32 to move it upward so that the upper clamping plate 30 can release the limit on the wide body of the T-shaped rod 23, and disassembly can be easily completed. The installation and disassembly process is efficient and quick, and has higher practicality.
