Description

Technical Field

[0001] This utility model relates to the technical field of busbar trunking, specifically a busbar trunking connection structure and busbar trunking based on improved tie bolts. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is commonly used in industrial and building electrical systems to efficiently and safely transmit high currents.

[0003] To achieve continuous power transmission and efficient distribution, multiple busbar trunking systems need to be connected together. Existing busbar trunking connections typically use dedicated connectors or joints to ensure reliable current transmission and safe connection. When mating a busbar trunking system with a connector, the conductive bars of the busbar trunking system and the connector are first aligned and inserted. After insertion, the threaded holes need to be aligned. This step requires that the threaded holes of the conductive bars on the connector and the conductive bars on the busbar trunking system be aligned to ensure that subsequent bolts can be easily inserted and tightened. This process may require the use of tools to assist in alignment and tightening, making the installation process for busbar trunking systems and connectors cumbersome and reducing connection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a busbar trunking connection structure based on improved tie bolts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A busbar trunking connection structure based on improved tie bolts includes a connecting frame for assisting the connection of two adjacent busbar trunkings. A second conductive busbar is provided in the connecting frame, and the two ends of the second conductive busbar can be alternately inserted with a first conductive busbar on the busbar trunking.

[0007] Two sets of elastic triggers are symmetrically arranged inside the connecting frame. A plug-in plate is connected to the busbar groove. The plug-in plate is inserted into the connecting frame to compress the elastic triggers.

The telescopic cylinder is connected to the lead screw via a toothed belt. A telescopic rod arranged axially along the telescopic cylinder is slidably mounted on the mounting bracket. One end of the telescopic rod can abut against the deflection plate, and the other end is inserted into the telescopic cylinder and forms a convex circle.

[0017] It also includes a second spring, which is installed inside the telescopic cylinder and sleeved on the telescopic rod. One end of the second spring is connected to the inner end of the telescopic cylinder, and the other end is connected to the convex circle.

[0029] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0030] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0032] Please see Figures 1-6 In this embodiment of the utility model, a busbar connection structure based on improved tie bolts includes a connecting frame 2 for assisting the connection of two adjacent busbars 1. A second conductive busbar 4 is provided in the connecting frame 2, and the two ends of the second conductive busbar 4 can be interleaved with the first conductive busbar 3 on the busbar 1 respectively.

[0033] Two sets of elastic triggers are symmetrically arranged inside the connecting frame 2. A plug plate 101 is connected to the busbar 1. The plug plate 101 is inserted into the connecting frame 2 and can compress the elastic triggers.

[0034] The limiting component, installed inside the connecting frame 2, can lock the plug plate 101 and squeeze the cross-connected first conductive bar 3 and second conductive bar 4;

[0035] The telescopic mechanism is installed inside the connecting frame 2. When the elastic trigger is triggered instantaneously, it controls the telescopic mechanism to extend or retract relative to each other, thereby driving the limiting component to work.

[0036] In this embodiment, when two adjacent busbar troughs 1 are connected, the busbar troughs 1 are respectively inserted into the connecting frame 2. When the plug-in plate 101 is inserted into the connecting frame 2, it squeezes the elastic trigger, so that the elastic trigger stores elastic potential energy. When the plug-in plate 101 is fully inserted into the connecting frame 2, the elastic force stored in the elastic trigger instantly triggers the telescopic mechanism to work. Under the drive of the telescopic mechanism, the symmetrically arranged limiting components can simultaneously generate reverse squeezing forces on the first conductive busbar 3 and the second conductive busbar 4, so that multiple first conductive busbars 3 and second conductive busbars 4 are tightly attached. At the same time, the limiting components can be inserted into the plug-in plate 101 to lock the plug-in plate 101. At the moment when the busbar trough 1 and the connecting frame 2 are connected, multiple first conductive busbars 3 and second conductive busbars 4 can be automatically and quickly tightly abutted, and the connection between the busbar trough 1 and the connecting frame 2 is stable. This avoids the complicated operation of accurately aligning the threaded holes and passing the tie bolts through the threaded holes in the traditional installation, thereby speeding up the installation speed of the busbar trough 1.

[0037] For further solutions to this utility model, please refer to [link / reference]. Figure 6 The limiting component includes a support shaft 16 fixedly installed in the connecting frame 2. A limiting rod 17 is slidably installed at one end of the support shaft 16. The limiting rod 17 can be inserted into the limiting hole 102 formed by the plug plate 101. An extrusion plate 18 is slidably installed at the other end. The extrusion plate 18 can extrude the first conductive busbar 3.

[0038] It also includes a threaded pusher installed in the connecting frame 2, which is connected to the extrusion plate 18 and the limiting rod 17 respectively, and is used to control the extrusion plate 18 and the limiting rod 17 to work simultaneously.

[0039] The threaded pusher includes a lead screw 13 rotatably mounted in the connecting frame 2. A threaded sleeve 14 is threadedly connected to the lead screw 13. Connecting rods 15 are symmetrically hinged to the threaded sleeve 14. The ends of the two connecting rods 15 away from the threaded sleeve 14 are respectively hinged to the extrusion plate 18 and the limiting rod 17.

[0040] It should be noted that: the two ends of the support shaft 16 are respectively formed into a first strip block 1601 and a second strip block 1602. The inner wall of the limiting rod 17 is provided with a first strip groove that is slidably adapted to the first strip block 1601, and the inner wall of the extrusion plate 18 is provided with a second strip groove that is slidably adapted to the second strip block 1602. Through the sliding cooperation of the first strip block 1601 with the first strip groove and the second strip block 1602 with the second strip groove, the limiting rod 17 and the extrusion plate 18 can be slidably connected to the support shaft 16 respectively.

[0041] Specifically, at the instant the plug-in plate 101 is fully inserted into the connecting frame 2, the lead screw 13 rotates under the drive of the telescopic mechanism, causing the threaded sleeve 14 to move linearly along the axis of the lead screw 13. When the threaded sleeve 14 moves toward the support shaft 16, the connecting rod 15 can squeeze the limiting rod 17 and the squeezing disc 18 to move linearly along the axis of the support shaft 16. The squeezing disc 18 moves in the opposite direction to the limiting rod 17. The limiting rod 17 moves into the insertion limiting hole 102 and locks the plug-in plate 101. At the same time, the symmetrically arranged squeezing disc 18 exerts pressure on the first conductive busbar 3, causing the two first conductive busbars 3 to move toward the middle at the same time. At the instant the busbar 1 and the connecting frame 2 are fully connected, multiple first conductive busbars 3 can automatically and quickly abut against the second conductive busbar 4, and ensure the stable connection between the busbar 1 and the connecting frame 2.

[0042] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The elastic trigger includes a support frame 5 fixedly installed in the connecting frame 2, and a deflection plate 6 is rotatably installed on the support frame 5. When the deflection plate 6 deflects, it can squeeze the telescopic mechanism.

[0043] It also includes a first spring 7 symmetrically arranged at both ends of the support frame 5, one end of the first spring 7 being rotatably connected to the support frame 5 and the other end being rotatably connected to the deflection plate 6.

[0044] Preferably, a first limiting block 501 and a second limiting block 502 are fixedly installed on the side end of the support frame 5, and the first limiting block 501 and the second limiting block 502 can respectively limit the deflection plate 6.

[0045] In the initial state, when the plug plate 101 is not inserted into the connecting frame 2, the first spring 7 is in a stretched state. At this time, the side end of the deflection plate 6 abuts against the first limiting block 501. The first spring 7 generates a force on the deflection plate 6 to deflect towards the first limiting block 501. Under the restriction of the first limiting block 501, the deflection plate 6 cannot rotate towards the direction of the first limiting block 501.

[0046] The aforementioned plug-in plate 101 is inserted into the connecting frame 2, extending deep into the connecting frame 2 until the deflection plate 6 abuts against it. Subsequently, the plug-in plate 101 continues to penetrate, compressing the deflection plate 6. The pressure of the plug-in plate 101 on the deflection plate 6 is greater than the elastic force of the first spring 7, allowing the deflection plate 6 to overcome the elastic force of the first spring 7 and deflect towards the second limiting block 502, thus allowing the plug-in plate 101 to move. When the deflection plate 6 deflects to a state where it is in a straight line with the support frame 5, the tension of the first spring 7 reaches its maximum value. The plug-in plate 101 is fully inserted into the connecting frame 2 at the instant... When the deflection plate 6 is driven past the balance state with the support frame 5, the first spring 7 generates a force on the deflection plate 6 to quickly deflect towards the second limit block 502, and the deflection plate 6 exerts pressure on the telescopic mechanism, so that when the busbar trough 1 and the connecting frame 2 are fully inserted, the limit rods 17 and the pressing plate 18 located at both ends of the connecting frame 2 can automatically and quickly lock in place, without the need for threaded hole alignment and tie bolts to pass through the limit, simplifying the installation process, and at the same time ensuring a more secure connection between the busbar trough 1 and the connecting frame 2, avoiding loosening or falling off due to vibration or external force.

[0047] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The telescopic mechanism includes a telescopic cylinder 10, which is rotatably mounted on the connecting frame 2 via a mounting bracket 8. The telescopic cylinder 10 is connected to the lead screw 13 via a toothed belt 12. A telescopic rod 9 is slidably mounted on the mounting bracket 8 along the axial direction of the telescopic cylinder 10. One end of the telescopic rod 9 can abut against the deflection plate 6, and the other end is inserted into the telescopic cylinder 10 and forms a convex circle 901.

[0048] It also includes a second spring 11, which is installed inside the telescopic cylinder 10 and sleeved on the telescopic rod 9. One end of the second spring 11 is connected to the inner end of the telescopic cylinder 10, and the other end is connected to the convex circle 901.

[0049] Preferably, the telescopic rod 9 has a threaded groove 902, and the telescopic cylinder 10 is movably provided with a ball bearing 1001 that slides and adapts to the threaded groove 902.

[0050] When the deflection plate 6 deflects to be in the same straight line as the support frame 5, the side wall of the deflection plate 6 abuts against the telescopic rod 9. When the deflection plate 6 passes the equilibrium state with the support frame 5 and deflects towards the direction of the second limiting block 502, it squeezes the telescopic rod 9, causing the telescopic rod 9 to move relative to the telescopic cylinder 10. Through the cooperation of the ball 1001 and the threaded groove 902, the telescopic cylinder 10 rotates itself when the telescopic rod 9 moves relative to the telescopic cylinder 10. At the same time, the second spring 11 is stretched to store elastic potential energy. Under the transmission of the toothed belt 12, it can drive the lead screw 13 to rotate synchronously to meet the rotation requirements of the lead screw 13. At the moment when the plug plate 101 is fully inserted into the connecting frame 2, the elastic potential energy stored in the first spring 7 supports the work simultaneously through the mechanical transmission control of the limiting rod 17 and the pressing plate 18. It can automatically press the first conductive busbar 3 and the second conductive busbar 4 while ensuring the stable connection between the busbar trough 1 and the connecting frame 2.
