Description

Technical Field

[0001] This utility model relates to the field of busbar trunking connection technology, specifically a busbar trunking connector. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute large amounts of power to various components in a distributed system. In indoor low-voltage power transmission trunk line projects, it has increasingly replaced wires and cables. Modern high-rise buildings and large workshops have large power demands, and for powerful currents, busbar trunking connectors are needed to conduct the current to ensure safety during use.

[0003] A busbar connector is disclosed in a related technology (publication number: CN212588040U). The disclosed technical solution is as follows: the waterproof effect is improved by the pads on the insulating partition, and the safety distance between the slot and the bolt is increased by the protrusions on the insulating partition; in addition, the temperature rise is reduced and the aging speed of the insulating material is slowed down by the use of multiple bolts to fix the structure between the busbar connectors, thus improving the service life of the busbar connector.

[0004] The above-disclosed technical solutions reveal the following problems: when connecting to the busbars of the bus trunking, the conductive plates on the bus trunking connector need to be inserted sequentially between the busbars and then locked. Existing bus trunking connectors cannot adjust the position of each conductive plate simultaneously, requiring them to be inserted one by one when connecting to the busbars, making the operation process cumbersome. To address this, we propose a new type of bus trunking connector.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Summary of the Invention

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the busbar trunking connection problem in the prior art, this utility model provides a busbar trunking connector that employs a conductive plate linkage adjustment structure combined with a locking structure to achieve stable busbar trunking connection. Its specific technical solution is as follows:

[0007] A busbar connector includes a mating frame, a guide post embedded in the inner cavity of the mating frame, an insulating plate uniformly sleeved on the outside of the guide post, a conductive plate disposed on the opposite face of two adjacent insulating plates, a scissor frame component disposed on the top of the mating frame, the lateral hinge joints of the scissor frame component being respectively connected to the insulating plate via extension shafts, the extension shafts being slidably disposed in the inner cavity of a through groove opened on the top of the mating frame, and a linkage pitch-changing assembly disposed on the top of the mating frame for driving the scissor frame component to retract and extend.

[0008] In the above technical solution, the linkage pitch-changing assembly includes a sealing cover covering the outside of the through groove. A lead screw is rotatably provided in the inner cavity of the sealing cover. A pitch-adjusting seat is symmetrically threaded on the outer wall of the lead screw. The pitch-adjusting seat is connected to the hinge point of the scissor frame component.

[0009] The inner cavity of the sealing cover is fitted with a directional slide rod parallel to the lead screw, and a slide block is sleeved on the outer wall of the directional slide rod. The slide block is fixedly installed on the outer wall of the extension shaft.

[0010] The outer wall of the extension shaft is fitted with a limiting plate that fits against the top of the docking frame. The slide is fixedly installed on the side wall of the limiting plate. The limiting plate and the adjusting seat are fixedly connected by a connecting frame.

[0011] The scissor frame includes a first frame and a second frame that are hinged to each other at their ends. A third frame is rotatably connected to the other end of the first frame. Multiple third frames are sequentially hinged end to end and then rotatably connected to the second frame. A fourth frame is rotatably connected to the other end of the second frame. Multiple fourth frames are sequentially joined end to end and then rotatably connected to the first frame.

[0012] Both sides of the docking frame are fitted with side sealing plates.

[0013] The inner wall of the side sealing plate and the outer wall of the docking frame form a receiving cavity. A protective plate is symmetrically slidably arranged in the inner cavity of the receiving cavity. A positioning bolt extending into the receiving cavity is threadedly connected to the side wall of the side sealing plate.

[0014] The inner wall of the cavity is symmetrically provided with sliding grooves on both sides, and the guard plate is symmetrically fixed with sliding tracks that are adapted to the sliding grooves on both sides.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the busbar connector:

[0016] 1. When connecting to the busbars of the bus trunking, the five insulating plates are spread out using a linkage pitch-changing assembly. Then, the five spread-out insulating plates are inserted between each busbar. Afterward, the linkage pitch-changing assembly causes the five insulating plates to converge towards the center simultaneously, thereby sequentially attaching and clamping the conductive plates onto the surface of the busbar. By simultaneously stretching and converging the five insulating plates, the busbar is connected and fixed at all points, thus facilitating the connection process of the bus trunking.

[0017] Second, when driving the five insulating boards to fold and unfold, rotate the lead screw to make the adjusting seat connected to the external thread of the lead screw move relative to each other or back to back. This causes the two adjusting seats to drive the two ends of the scissor frame component to move relative to each other or back to back, thereby enabling the scissor frame component to unfold or fold laterally. This ensures the stability of the insulating board position adjustment process and thus ensures the stability of the connection with the busbar.

[0018] Third, the directional sliding rod parallel to the lead screw ensures the stability of the folding and changing process of the scissor frame components, thereby ensuring the stability of the busbar connection.

[0019] Fourth, the longitudinal positioning of the scissor frame components is limited by the limiting plate to prevent the scissor frame components from shifting position, thereby ensuring the stability of the busbar connection.

[0020] 5. After the connector is connected to the busbar of the bus trunking, slide the protective plate out from the inside of the receiving cavity, and then tighten the positioning bolts to fix it, thereby protecting the connection of the busbar of the bus trunking. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] A busbar connector includes a mating frame 1. Guide posts 2 are embedded in the inner cavity of the mating frame 1. Insulating plates 3 are uniformly sleeved on the outside of the guide posts 2. Conductive plates 4 are disposed on the opposite surfaces of two adjacent insulating plates 3. The mating frame 1 is a frame body formed by four plates sequentially and circumferentially fixed together. Two parallel guide posts 2 are horizontally fixedly embedded in the inner cavity of the mating frame 1, near the upper and lower inner walls, with the two guide posts 2 located at the center.

[0030] Five insulating plates 3 are fixedly mounted with sliding seats 10 at their upper and lower edges. Through holes penetrating the inner cavity are horizontally formed on the surface of each sliding seat 10, with the diameter corresponding to the guide posts 2. Each of the five insulating plates 3 is movably fitted onto the outside of the guide posts 2 via the sliding seats 10 near their edges, allowing the five insulating plates 3 to slide against the outer walls of the two guide posts 2. The two parallel guide posts 2 ensure the stability of the insulating plates 3 during movement. Conductive plates 4 are fixedly mounted on the opposite surfaces of the insulating plates 2 at the two edges, and on both sides of the three middle insulating plates 2, ensuring that each pair of adjacent insulating plates 2 has a conductive plate 4 on its opposite surface.

[0031] The top of the connecting frame 1 is equipped with a scissor frame component 5. The lateral hinges of the scissor frame component 5 are connected to the insulating plate 3 via extension shafts 21. The extension shafts 21 are slidably disposed within the cavity of the through slot 7 opened at the top of the connecting frame 1. The scissor frame component 5 is a folding frame composed of multiple frame rods hinged sequentially, and it is composed of multiple foldable and stretchable quadrilateral frame bodies. The bottom of the shafts at the five lateral hinge connections of the scissor frame component 5 is fixedly connected to the extension shafts 21.

[0032] A transverse slot 7, with a width corresponding to that of the extension shaft 21, is horizontally cut at the top of the connecting frame 1. A mounting bracket 27 is fixedly embedded in the top of each insulating plate 3, and a bearing is embedded in the top of the mounting bracket 27. The top end of the extension shaft 21 is fixedly connected to the transverse hinge shaft of the scissor frame component 5, and the bottom end of the extension shaft 21 passes through the inner cavity of the through slot 7 and is embedded in the bearing cavity at the top of the mounting bracket 27. The extension shaft 21 slides against the inner wall of the through slot 7.

[0033] The top of the docking frame 1 is equipped with a linkage pitch-changing assembly that drives the scissor frame component 5 to retract and extend. The linkage pitch-changing assembly enables the scissor frame component 5 to fold and extend. As the scissor frame component 5 folds and extends, the lateral hinge of the scissor frame component 5 drives the five insulating plates 3 to converge and disperse towards the center through the extension shaft 5.

[0034] When connecting to the busbars of the bus trunking, the five insulating plates 3 are spread out using a linkage pitch-changing assembly. The five spread insulating plates 3 are then inserted between the various busbars, and the linkage pitch-changing assembly simultaneously brings the five insulating plates 3 together towards the center, thereby sequentially attaching and securing the conductive plates 4 to the surface of the busbars. By simultaneously stretching and bringing together the five insulating plates 3, the busbars are connected and fixed at all points, thus facilitating the bus trunking connection process.

[0035] The linkage pitch-changing assembly includes a sealing cover 6 that covers the outside of the through groove 7. The sealing cover 6 is fixedly installed on the top of the docking frame 1, and the sealing cover 6 covers the through groove 7 inside, thus ensuring the sealing of the through groove 7 and protecting the busbar connector.

[0036] A lead screw 19 is rotatably mounted inside the sealing cover 6. The outer wall of the lead screw 19 is symmetrically threaded with adjusting seats 26. Bearings are embedded on both sides of the inner wall of the sealing cover 6, and two bearings are embedded at each end of the lead screw 19. Two sets of external threads with opposite pitches are formed on the outer wall of the lead screw 19 from both ends toward the center. The two adjusting seats 26 are connected to the two sets of external threads through threaded through holes penetrating the inner cavity. Rotating the lead screw 19 causes the two adjusting seats 26 to move relative to each other or back to back. One end of the lead screw 19 penetrates the side wall of the sealing cover 6 and extends to the outside, where an anti-slip sleeve is fitted onto the outer side of the lead screw 19 extending outside the sealing cover 6.

[0037] The adjustable distance seat 26 is connected to the hinge point of the scissor frame component 5, and the extension shaft 21 of the hinge points at both ends of the scissor frame component 5 is connected to the two adjustable distance seats 26.

[0038] When driving the five insulating plates 3 to fold and unfold, rotating the lead screw 19 causes the adjusting seats 26 connected to the external thread of the lead screw 19 to move relative to or away from each other. This causes the two adjusting seats 26 to drive the two ends of the scissor frame component 5 to move relative to or away from each other, thereby allowing the scissor frame component 5 to unfold or fold laterally. This ensures the stability of the position adjustment process of the insulating plates 3, and thus ensures the stability of the connection with the busbar trunking.

[0039] It is worth noting that a directional slide rod 20 parallel to the lead screw 19 is embedded in the inner cavity of the sealing cover 6. A slide seat 23 is sleeved on the outer wall of the directional slide rod 20, and the slide seat 23 is fixedly installed on the outer wall of the extension shaft 21. Two parallel directional slide rods 20 are fixedly installed in the inner cavity of the sealing cover 6, and the two directional slide rods 20 are positioned parallel to the lead screw 19. The slide seat 23 is simultaneously movably sleeved on the outside of the two directional slide rods 20 through a through hole penetrating the inner cavity, so that the slide seat 23 slides against the outer wall of the directional slide rod 20. The two slide seats 23 are symmetrically fixed on both sides of the outer wall of the directional slide rod 20.

[0040] The directional slide bar 20, which is parallel to the lead screw 19, ensures the stability of the folding and changing process of the scissor frame component 5, thereby ensuring the stability of the busbar connection.

[0041] A limiting plate 22, which fits against the top of the docking frame 1, is sleeved on the outer wall of the extension shaft 21. A slide 23 is fixedly installed on the side wall of the limiting plate 22. The limiting plate 22 and the adjusting seat 26 are fixedly connected by a connecting frame 25. The limiting plate 22 is fixedly sleeved on the outside of the extension shaft 21 through a mounting hole that penetrates the inner cavity, and slides against the top of the docking frame 1. Two bases 24 are symmetrically fixedly installed on the top of the limiting plate 22. The slide 23 is fixedly installed on the top of the base 24. One end of the connecting frame 25 is fixedly installed on the surface of the base 24, and the other end of the connecting frame 25 is fixedly installed on the surface of the adjusting seat 26. The limiting plate 22 longitudinally limits the scissor frame component 5, preventing the scissor frame component 5 from shifting position, thereby ensuring the stability of the busbar connection.

[0042] The scissor frame component 5 includes a first link 14 and a second link 15 hinged at their ends. A third link 17 is rotatably connected to the other end of the first link 14. Multiple third links 17 are sequentially hinged end-to-end and then rotatably connected to the second link 15. A fourth link 16 is rotatably connected to the other end of the second link 15. Multiple fourth links 16 are sequentially crossed end-to-end and then rotatably connected to the first link 14. Each third link 17 and fourth link 16 is rotatably connected at its intersection. One end of each set of first links 14 and second links 15 is hinged to a shaft, and the hinged ends are located at their respective side edges.

[0043] The other end of the first connecting frame 14 is rotatably connected to one end of the fourth connecting frame 16 via a shaft. The fourth connecting frame 16 is sequentially hinged end-to-end via shafts, and the end of the fourth connecting frame 16 at the end is hinged to the other end of the second connecting frame 15 via a shaft. The other end of the second connecting frame 15 is hinged to one end of the third connecting frame 17 via a shaft, and the third connecting frame 17 is sequentially hinged end-to-end via shafts. The end of the third connecting frame 17 at the end is hinged to one end of the first connecting frame 14 via a shaft, and each third connecting frame 17 is hinged to the fourth connecting frame 16 at its center intersection via a shaft. This allows the folding frame component 5 to be folded and unfolded.

[0044] Side sealing plates 8 are fitted to both sides of the docking frame 1. The two side sealing plates 8 are fixedly installed on the two sides of the docking frame 1 respectively, and the side sealing plates 8 on both sides ensure the sealing of the docking frame 1, thereby providing protection for the busbar conductive plate.

[0045] In addition, the inner wall of the side sealing plate 8 and the outer wall of the docking frame 1 form a receiving cavity 18. A protective plate 9 is symmetrically slidably arranged in the inner cavity of the receiving cavity 18. A positioning bolt 12 extending into the inside of the receiving cavity 18 is threadedly connected to the side wall of the side sealing plate 8.

[0046] Two protective plates 9 are symmetrically slid into the cavity 18. After the connector is connected to the busbar of the bus trough, the protective plates 9 are slid out of the cavity 18 and then the positioning bolts 12 are tightened to fix them, thereby protecting the connection of the busbar of the bus trough.

[0047] In addition, symmetrical grooves 13 are provided on both sides of the inner wall of the receiving cavity 18, and symmetrical slide rails 11 adapted to the grooves 13 are fixed on both sides of the guard plate 9. The guard plate 9 slides in the grooves 13 through the slide rails 11, thereby ensuring the stability of the guard plate 9 during the position adjustment process.

[0048] This embodiment is a busbar connector. The working principle is as follows: when connected to the busbar of the busbar, the lead screw 19 is rotated, so that the adjusting seat 26 connected to the external thread of the lead screw 19 moves back to back, so that the two adjusting seats 26 respectively drive the two ends of the scissor frame component 5 to move back to back, so that the scissor frame component 5 unfolds laterally.

[0049] Then, the five separate insulating boards 3 are inserted between each busbar.

[0050] Then, rotate the lead screw 19 again, causing the adjusting seat 26 connected to the external thread of the lead screw 19 to move relative to each other. This causes the two adjusting seats 26 to drive the two ends of the scissor frame component 5 to move relative to each other. Through the linkage variable pitch component, the five insulating plates 3 are simultaneously converged towards the center, thereby sequentially attaching and clamping the conductive plates 4 onto the surface of the busbar.
