Description
Technical Field
[0001] This utility model relates to the field of busbar trunking connection technology, specifically a pre-tightening connection structure for busbar trunking with intelligent force sensing. Background Technology
[0002] Busbar trunking, as a highly efficient and safe power transmission device, is widely used in modern industrial and civil buildings. However, existing technologies have some shortcomings in the actual installation and connection process of busbar trunking. Traditional busbar trunking connection methods typically use bolts to clamp multiple misaligned copper busbars to achieve the connection of two busbar trunking sections.
[0003] This existing technology lacks a pre-fixing step before installing bolts, which may lead to loose connections during subsequent fixing operations. Specifically, during long-term operation, factors such as vibration and thermal expansion and contraction may cause tiny gaps to form between the copper busbars, increasing resistance during power transmission, reducing transmission efficiency, and wasting energy. Simultaneously, localized overheating may pose safety hazards, and in severe cases, even damage the busbar, affecting the normal operation of the entire electrical system. Furthermore, frequent maintenance and replacement increase operating costs. Utility Model Content
[0004] The purpose of this invention is to provide a pre-tightening docking structure for busbar trunking with intelligent force sensing, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A pre-tightening docking structure for intelligent force sensing busbar trunking includes a metal shell and copper busbars disposed inside the metal shell. The copper busbars are configured in multiple and evenly distributed. Protective plates are provided at the ends of the metal shell and on both sides of the multiple copper busbars. A mating rod is provided on the protective plate at one end of the metal shell, and an instantaneous deflection assembly that can be adapted to the mating rod is provided on the protective plate at the other end of the metal shell. A trigger switch that cooperates with the instantaneous deflection assembly is also provided on the protective plate at the other end of the metal shell. When the two metal shells drive the multiple copper busbars to approach each other and perform misaligned docking, and when the ends of the two protective plates are in contact, the mating rod will activate the trigger switch through the instantaneous deflection assembly. One end of the metal casing is also provided with a pre-clamping component. When the trigger switch is turned on, the pre-clamping component will start to operate and can clamp multiple copper busbars that are misaligned and connected to each other.
[0006] As a further embodiment of this utility model: The instantaneous yaw assembly includes a yaw rod, a cylinder, and a central shaft. The cylinder is disposed on the protective plate, and the central shaft is disposed on the protective plate and located directly above the cylinder. One end of the swing arm is rotatably connected to the central shaft, and the other end of the swing arm can be engaged with the mating rod and the trigger switch respectively.
[0007] As a further improvement of this utility model: The protective plate is provided with a limit post, and the swing arm is located between the trigger switch and the limit post.
[0008] As a further improvement of this utility model: The swing arm is provided with a protruding post, and the cylinder and the protruding post are connected by a hook spring. Under the action of the hook spring, the swing arm abuts against the limiting post. When the ends of the two protective plates are in contact, the mating rod will push the swing arm to rotate and pass through the vertical position. During this process, the hook spring is stretched continuously. When the swing arm reaches the vertical position, the hook spring is stretched to its maximum. When it passes through the vertical position, the hook spring will quickly contract and drive the swing arm to deflect quickly, thus activating the trigger switch.
[0009] As a further improvement of this utility model: The pre-clamping assembly includes a first trapezoidal block and a second trapezoidal block, wherein the first trapezoidal block is slidably disposed on the protective plate along a direction perpendicular to the length of the copper busbar; A clamping plate is provided at one end of the first trapezoidal block, and the clamping plate is located between the copper busbar and the protective plate.
[0010] As a further improvement of this utility model: The protective plate is provided with a sliding groove along the length of the copper busbar, and a sliding block is slidably disposed in the sliding groove, with the second trapezoidal block disposed on the sliding block; The inclined surface of the second trapezoidal block is in contact with the inclined surface of the first trapezoidal block. When the second trapezoidal block slides, the first trapezoidal block will drive the clamping plate to clamp the copper busbar.
[0011] As a further improvement of this utility model: A solenoid valve is provided on the metal casing, and the solenoid valve is electrically connected to the trigger switch; The output end of the solenoid valve is provided with a movable plate, and the movable plate and the slide are fixedly connected by a push rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting a mating rod, an instantaneous deflection assembly, and a trigger switch at the end of the metal casing, during the busbar docking process, when the two metal casings drive the copper busbars closer together and the ends of the protective plates fit together, the mating rod can accurately activate the trigger switch through the instantaneous deflection assembly. This process not only realizes automated pre-clamping action, improving docking efficiency and convenience, but also ensures that the pre-clamping assembly can quickly and evenly clamp the misaligned copper busbars, laying the foundation for subsequent fixing operations.

[0024] Please see Figures 1-8 In this embodiment of the present invention, a busbar pre-tightening docking structure with intelligent force sensing includes a metal shell 1 and copper busbars 2 disposed inside the metal shell 1. The copper busbars 2 are configured in multiple and evenly distributed. Protective plates 3 are provided at the ends of the metal shell 1 and on both sides of the multiple copper busbars 2. A mating rod 4 is provided on the protective plate 3 at one end of the metal shell 1, and an instantaneous deflection assembly that can be adapted to the mating rod 4 is provided on the protective plate 3 at the other end of the metal shell 1. A trigger switch 5 that cooperates with the instantaneous deflection assembly is also provided on the protective plate 3 at the other end of the metal shell 1. When the two metal shells 1 respectively drive the multiple copper busbars 2 to approach each other and perform misaligned docking, and when the ends of the two protective plates 3 are in contact, the mating rod 4 will activate the trigger switch 5 through the instantaneous deflection assembly. One end of the metal casing 1 is also provided with a pre-clamping component. When the trigger switch 5 is turned on, the pre-clamping component will start to operate and can clamp multiple copper busbars 2 that are misaligned and connected to each other.
[0025] In this scheme, the structure consists of: the busbar pre-tightening docking structure includes a metal shell 1 and copper busbars 2 set inside the metal shell 1. The copper busbars 2 are set in multiple and evenly distributed to ensure the stability and uniformity of power transmission; at the end of the metal shell 1 and on both sides of the multiple copper busbars 2, there are protective plates 3. The function of the protective plates 3 is to protect the copper busbars 2 and provide structural support for subsequent docking operations. Docking process: When two busbar trunkings need to be docked, the two metal shells 1 respectively drive the multiple copper busbars 2 inside them to approach each other and perform staggered docking; during the docking process, when the ends of the two protective plates 3 are in contact, the mating rod 4 located on one end of the protective plate 3 of one of the metal shells 1 will cooperate with the instantaneous deflection component on the other end of the protective plate 3 of the other metal shell 1; through the action of the instantaneous deflection component, the mating rod 4 can accurately open the trigger switch 5 set on the protective plate 3; Pre-clamping action: Once the trigger switch 5 is turned on, the pre-clamping component set at one end of the metal housing 1 will be activated and start running; the function of the pre-clamping component is to quickly and evenly clamp multiple copper busbars 2 that are misaligned and connected to each other, so as to achieve preliminary pre-fixation.
[0026] As a further embodiment of this utility model, the instantaneous yaw assembly includes a swing arm 6, a cylinder 7 and a central shaft 8. The cylinder 7 is disposed on the protective plate 3, and the central shaft 8 is disposed on the protective plate 3 and located directly above the cylinder 7. One end of the swing arm 6 is rotatably connected to the central shaft 8, and the other end of the swing arm 6 can be engaged with the mating rod 4 and the trigger switch 5 respectively; The protective plate 3 is provided with a limit post 10, and the swing rod 6 is located between the trigger switch 5 and the limit post 10; The swing rod 6 is provided with a protruding post 9, and the cylinder 7 and the protruding post 9 are connected by a hook spring 11. Under the action of the hook spring 11, the swing rod 6 abuts against the limiting post 10. When the ends of the two protective plates 3 are in contact, the mating rod 4 will push the swing rod 6 to rotate and pass through the vertical position. During this process, the hook spring 11 is stretched continuously. When the swing rod 6 reaches the vertical position, the hook spring 11 is stretched to the maximum. When it passes through the vertical position, the hook spring 11 will quickly contract and drive the swing rod 6 to deflect quickly and turn on the trigger switch 5.
[0027] In this embodiment, in the initial state, the hook spring 11 is in a certain pre-stretched state, so that the swing arm 6 abuts against the limiting post 10 under the action of the spring force and remains stable; When the ends of the protective plates 3 of the two busbar trunking are in contact, the mating rod 4 on one of the protective plates 3 will contact the swing rod 6 on the other protective plate 3. As the two protective plates 3 get closer, the mating rod 4 begins to push the swing rod 6 to rotate around the central axis 8. During the rotation, the protrusion 9 on the swing rod 6 will cause the hook spring 11 to be stretched continuously, so that the spring stores elastic potential energy. When the swing rod 6 reaches the vertical position, the stretch of the hook spring 11 reaches its maximum value, and the elastic potential energy stored in the spring is also the maximum. Once the swing rod 6 passes the vertical position, the hook spring 11 begins to contract rapidly, using the stored elastic potential energy to drive the swing rod 6 to deflect rapidly. This rapid deflection action allows the other end of the swing rod 6 to quickly touch the trigger switch 5, thereby completing the entire instantaneous deflection process, realizing the opening of the trigger switch 5, and then triggering the subsequent pre-clamping component action.
[0028] As a further embodiment of this utility model, the pre-clamping assembly includes a first trapezoidal block 12 and a second trapezoidal block 13, wherein the first trapezoidal block 12 is slidably disposed on the protective plate 3 along a direction perpendicular to the length of the copper busbar 2; A clamping plate 14 is provided at one end of the first trapezoidal block 12, and the clamping plate 14 is located between the copper busbar 2 and the protective plate 3; The protective plate 3 has a sliding groove 301 along the length of the copper busbar 2, and a sliding seat 15 is slidably disposed in the sliding groove 301. The second trapezoidal block 13 is disposed on the sliding seat 15. The inclined surface of the second trapezoidal block 13 is in contact with the inclined surface of the first trapezoidal block 12. When the second trapezoidal block 13 slides, the first trapezoidal block 12 will drive the clamping plate 14 to clamp the copper busbar 2. A solenoid valve 16 is provided on the metal housing 1, and the solenoid valve 16 is electrically connected to the trigger switch 5; The output end of the solenoid valve 16 is provided with a movable plate 17, and the movable plate 17 and the slide block 15 are fixedly connected by a push rod 18.
[0029] In this embodiment, when the trigger switch 5 in the instantaneous yaw assembly is turned on, the trigger switch 5 sends an electrical signal to the solenoid valve 16; the solenoid valve 16 is activated after receiving the signal, and its output pushes the moving plate 17 to move along the length direction of the copper busbar 2; the moving plate 17 drives the slide block 15 to slide in the slide groove 301 through the push rod 18; as the slide block 15 slides, the second trapezoidal block 13 moves along the slide groove 301; since the inclined surface of the second trapezoidal block 13 is in contact with the inclined surface of the first trapezoidal block 12, the sliding of the second trapezoidal block 13 will push the first trapezoidal block 12 to move upward along the direction perpendicular to the length of the copper busbar 2; the movement of the first trapezoidal block 12 drives the clamping plate 14 to move closer to the copper busbar 2, thereby clamping the copper busbar 2 and achieving pre-clamping.
