Description

Technical Field

[0001] This invention relates to the field of busbar technology, specifically to a busbar angle conversion connection structure. Background Technology

[0002] With the rapid development of modern building electrical technology, busbar trunking, as a high-efficiency power transmission and distribution equipment, is widely used in power supply systems of high-rise buildings, data centers, factory workshops and other places due to its advantages such as large current carrying capacity, compact structure and good heat dissipation performance. In the actual process of laying electrical lines, due to the complexity of building structure, busbar trunking often needs to turn, cross obstacles or change the laying path in the horizontal or vertical direction, which inevitably requires the use of angle conversion connection structure.

[0003] However, in the use of existing connection structures, once the locking fails, the connection parts of the busbar trunking will experience slight relative displacement or shaking, which will directly cause gaps in the contact surfaces of the internal conductive busbars, resulting in a sharp increase in contact resistance. The connection is very prone to oxidation and burning due to overheating, and in severe cases, it may even cause electrical fires or power outages. Summary of the Invention

[0004] The purpose of this invention is to provide a busbar angle conversion connection structure. By setting an adjustment part, the problem of slight relative displacement or shaking of the busbar connection part occurs when the locking fails during use. This directly leads to gaps in the contact surface of the internal conductive busbar, causing a sharp increase in contact resistance. The connection is also prone to oxidation and burning due to overheating, and in severe cases, it may even cause electrical fires or power outages.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a busbar angle conversion connection structure, comprising two busbars and further comprising: an adjustment part mounted on the two busbars; a fixing part disposed on the two busbars; the adjustment part including a limiting component mounted on the two busbars; and two adapter components, each disposed on one of the two busbars; the limiting component including a mounting plate disposed on the two busbars, the mounting plate having a limiting groove, the inner wall of the limiting groove being provided with two limiting rings, each of the two limiting rings being slidably connected to a... The slide rods have connecting blocks fixedly connected to their bottoms, and rotating shafts rotatably connected to both connecting blocks. Two protrusions are fixedly connected to the outer walls of both rotating shafts, and handles are fixedly connected to the outer walls of several protrusions. Elastic elements are provided on both slide rods. Two limiting rings, two slide rods, two connecting blocks, two rotating shafts, several protrusions, and two handles are arranged in a mirror image. The elastic element includes a spring sleeved on the outer wall of the slide rod. The top of the spring is fixedly connected to the connecting block, and the bottom of the spring is fixedly connected to the limiting ring. After installation, the spring is in a compressed state.

[0006] Furthermore, the fixing part includes an installation component disposed on the busbar trunking; and a connecting component installed on the busbar trunking, wherein two busbar trunkings are connected together by the installation component and the connecting component.

[0007] Furthermore, the adapter component includes two fixing blocks that are fixedly connected to the bottom of the two busbar troughs respectively. A sliding groove is provided on the fixing block. A slider is slidably connected to the inner wall of the sliding groove. A connecting block is fixedly connected to the bottom of the slider. The sliding groove is T-shaped and the slider is adapted to the sliding groove.

[0008] Furthermore, the mounting assembly includes a hollow rod fixedly connected to the inner wall of the bottom of the mounting plate. A threaded rod is rotatably connected to the inner wall of the hollow rod. A second groove is provided on the threaded rod. A limiting block is slidably connected within the second groove. The limiting block extends outside the second groove and is threadedly connected to the threaded rod. An auxiliary block is fixedly connected to the top of the threaded rod. An extrusion member is provided on the hollow rod. The hollow rod in the middle is fixedly connected to the mounting plate, while the hollow rods on both sides are not fixedly connected to the mounting plate. The limiting block is cross-shaped. Four second grooves are provided and distributed in a circumferential array. The limiting blocks are adapted to the second grooves. The extrusion member includes an extrusion block threadedly connected to the outer wall of the hollow rod. The extrusion block contacts the connecting plate above and is hexagonal in shape.

[0009] Furthermore, the connecting assembly includes two connecting plates 1 disposed between two busbar slots, the hollow rod passing through the two connecting plates 1, a plurality of connecting plates 2 disposed between the two busbar slots, the left and right sides of the plurality of connecting plates 2 extending into the two busbar slots respectively, fasteners being provided between the plurality of connecting plates 2, the hollow rod passing through the plurality of connecting plates 2, the limiting block contacting the connecting plate 1 located below, and the fasteners including a plurality of pads disposed between the plurality of connecting plates 2, the plurality of pads being distributed in a linear array.

[0010] The present invention has the following beneficial effects: 1. This invention, by setting an adjustment part, allows for angle adjustment by first turning the handle downwards. The eccentrically positioned protrusion at the end of the handle disengages its protruding portion from the limiting ring, releasing the pushing force on the limiting ring. At this point, the previously compressed spring recovers its elastic deformation, pushing the limiting ring out of the limiting groove, thus releasing the mechanical lock on the busbar. After unlocking, the busbar can rotate around the rotation center. Because the trajectory of the limiting groove is not concentric with the rotation center, the slider on the connecting component will adaptively slide within the first sliding groove during rotation to compensate for the radial displacement difference during rotation, ensuring smooth movement. When the busbar rotates to the target angle, pushing the handle upwards causes the protruding portion of the protrusion to push the limiting ring again, overcoming spring resistance and pressing it back into the corresponding limiting groove, achieving relocking and completing the angle adjustment. The spring's rebound force and the locking action between the limiting ring and the limiting groove provide a continuous and stable locking force, effectively preventing the busbar from shifting due to vibration or its own weight during long-term operation.

[0011] 2. This invention, by setting up a fixing part, firstly rotates the auxiliary block to drive the threaded rod to rotate during the initial installation, causing the limiting block to slide downwards along the second slide groove, increasing the distance between it and the extrusion block, so that the second connecting plate is in a relaxed state, thus easily inserting into the busbar trough; then, the mounting components on both sides are initially fixed, keeping them in a state that can rotate slightly, and then the auxiliary block of the middle mounting component is rotated to drive the limiting block to move upwards. Utilizing the wedge-shaped engagement between the limiting block and the extrusion block, the first connecting plate, the second connecting plate, and the pad are tightly pressed together, and the busbar trough is clamped at the same time, achieving complete locking of the middle part; after the middle is locked, the busbar trough can be finely adjusted in angle, and after determining the angle, the components on both sides are completely locked, thus completing the overall installation. This effectively solves the problem of difficult alignment and insertion of traditional rigid connections. The relaxed state during the initial installation allows the conductive busbar to slide in easily, greatly reducing the requirements for installation and the labor intensity of construction personnel.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-7As shown, the present invention is a busbar angle conversion connection structure, including two busbars 111, and further including: an adjustment part 2, which is installed on the two busbars 111; and a fixing part 3, which is disposed on the two busbars 111. Adjustment unit 2 includes a limiting component 21, which is installed on two busbar troughs 111; and two adapter components 22, which are respectively installed on the two busbar troughs 111. The limiting component 21 includes a mounting plate 211 installed on the two busbar troughs 111. The mounting plate 211 has a limiting groove 212. The inner wall of the limiting groove 212 is provided with two limiting rings 213. Each limiting ring 213 is slidably connected to a sliding rod 214. The bottom of each sliding rod 214 is fixedly connected to a connecting block 215. Each connecting block 215 is rotatably connected to a rotating shaft 216. The outer wall of each rotating shaft 216 is fixedly connected to two protrusions 217. The outer wall of several protrusions 217 is fixedly connected to a handle 218. The two sliding rods 214 are provided with elastic elements. The two limiting rings 213, two sliding rods 214, two connecting blocks 215, and two rotating shafts 216 are all included. 16. Several protrusions 217 and two handles 218 are arranged in a mirror image. The elastic element includes a spring 219 sleeved on the outer wall of the slide rod 214. The top of the spring 219 is fixedly connected to the connecting block 224, and the bottom of the spring 219 is fixedly connected to the limiting ring 213. After installation, the spring 219 is in a compressed state. The adapter component 22 includes two fixing blocks 221 fixedly connected to the bottom of the two busbar troughs 111 respectively. The fixing block 221 has a first slide groove 222. The inner wall of the first slide groove 222 is slidably connected to a slider 223. The bottom of the slider 223 is fixedly connected to the connecting block 224. The first slide groove 222 is T-shaped. The slider 223 is adapted to the first slide groove 222. By setting the adjustment part 2, the spring's rebound force and the locking cooperation between the limiting ring and the limiting groove can provide a continuous and stable locking force, effectively preventing the busbar trough from shifting due to vibration or its own weight during long-term operation.

[0018] The fixing part 3 includes a mounting assembly 31, which is mounted on the busbar trough 111; and a connecting assembly 32, which is mounted on the busbar trough 111. The two busbar troughs 111 are connected together by the mounting assembly 31 and the connecting assembly 32. The mounting assembly 31 includes a hollow rod 311 fixedly connected to the inner wall of the bottom of the mounting plate 211. A threaded rod 312 is rotatably connected to the inner wall of the hollow rod 311. A second groove 313 is provided on the threaded rod 312. A sliding connection includes a limiting block 314, which extends beyond the second slide groove 313. The limiting block 314 is threadedly connected to the threaded rod 312. An auxiliary block 315 is fixedly connected to the top of the threaded rod 312. An extrusion member is provided on the hollow rod 311. The hollow rod 311 in the middle is fixedly connected to the mounting plate 211, while the hollow rods 311 on both sides are not fixedly connected to the mounting plate 211. The limiting block 314 is cross-shaped, and the second slide groove 313 has four sections arranged in a circular array. The limiting block 314 is adapted to the second slide groove 313. The extrusion component includes an extrusion block 316 threaded to the outer wall of the hollow rod 311. The extrusion block 316 contacts the upper connecting plate 321. The extrusion block 316 is hexagonal in shape. The connecting assembly 32 includes two connecting plates 321 disposed between two busbar grooves 111. The hollow rod 311 passes through the two connecting plates 321. Several connecting plates 322 are disposed between the two busbar grooves 111. The left and right sides of the several connecting plates 322 extend into the two busbar grooves 111 respectively. Fasteners are disposed between the several connecting plates 322. The hollow rod 311 passes through the several connecting plates 322. The limiting block 314 contacts the lower connecting plate 321. The fasteners include several pads 323 disposed between the several connecting plates 322. The several pads 323 are distributed in a linear array. By setting the fixing part 3, the problem of difficult alignment and insertion of traditional rigid connections is effectively solved. The initial relaxed state during installation allows the busbar to slide in easily, greatly reducing the installation requirements and the labor intensity of the construction personnel.

[0019] In use, first install the busbar trough 111 onto the mounting plate 211. During installation, keep the connecting plate 322 loose. To loosen the connecting plate 322, rotate the auxiliary block 315. The auxiliary block 315 will then slide downwards along with the limiting block 314. As the limiting block 314 slides, it will move within the sliding groove 313. With the movement of the limiting block 314, the distance between it and the pressing block 316 will increase, thus preventing pressure on the connecting plate 322. After the connecting plate 322 is loosened, insert it into the corresponding busbar trough 111. After insertion, install the mounting components 31 on both sides, and then tighten them. When tightening, rotate the auxiliary block 315 to tighten the screws. When the threaded rod 312 rotates, it will cause the limiting block 314 to move upward. When the limiting block 314 moves upward, it will squeeze the connecting plate 321 below. During the squeezing, the distance between the limiting block 314 and the squeezing block 316 will also decrease. At this time, the busbar 111 and the connecting plate 322 will be squeezed. This achieves the effect of pre-installing the busbar 111 on the mounting plate 211. During installation, the mounting components 31 on both sides do not need to be tightened too much, so that they can rotate slightly. After the two sides are fixed, the mounting component 31 in the middle is completely tightened so that it can be firmly locked. The connecting plate 321, the connecting plate 322 and the pad 323 are connected. This achieves the effect of installing the busbar 111. After installation, the angle between the two busbar grooves 111 can be adjusted. When adjusting, turn the handle 218 downwards. Because the protrusion 217 is eccentric, the protruding position of the protrusion 217 will stop pushing the limiting ring 213 when the handle 218 moves. The compressed spring 219 will push the limiting ring 213 out of the limiting groove 212, thus removing the limitation on the limiting ring 213. At this point, the busbar groove 111 can be rotated. However, because the limiting groove 212 is not concentric with the center of rotation of the busbar groove 111, the slider 223 will remain within the first groove 222 during rotation. The sliding mechanism coordinates with the movement of the busbar 111. After rotating to a certain position, the handle 218 is pushed upwards. At this time, the part of the protrusion 217 pushed up will push the limiting ring 213 again. The limiting ring 213 will then be locked into the limiting groove 212 again. When pushed, the spring 219 will be compressed again. After the limiting ring 213 enters the limiting groove 212, it will form a limit, thereby achieving the effect of rotating and fixing the busbar 111. After being fixed, the busbar 111 will not move arbitrarily, thus avoiding poor contact caused by the movement of the busbar 111.
