Description

Technical Field

[0001] This application relates to the field of busbar trunking technology, and in particular to a busbar trunking joint protection device. Background Technology

[0002] Busbar trunking is a high-efficiency power transmission device, mainly used in high-current power supply scenarios such as buildings and industrial plants. It consists of a metal casing, conductive bars, insulation materials, and accessories. It can replace traditional cable trays, achieving centralized power distribution and transmission. Its core advantages lie in its large current carrying capacity, good heat dissipation, convenient installation and maintenance, strong safety protection, and adaptability to complex wiring environments. Depending on the application, it can be divided into compact, air-insulated, and fire-resistant types, and is widely used in power transmission systems in high-rise buildings, data centers, and factory production lines.

[0003] Chinese patent CN218005821U discloses a busbar joint protection device, including a connecting structure and a shielding structure. The shielding structure is located around the connecting structure and surrounds it. The connecting structure includes a first busbar, a side wall, a fixing block, a plug, a partition block, a connecting block, and a second busbar. The ends of the first busbar and the second busbar correspond to each other. Two fixing blocks are respectively placed at the ends of the first and second busbars. One fixing block is fixedly connected to the first busbar, and a large sleeve is fixedly connected to the first busbar by connecting screws. A small sleeve is fixedly connected to the second busbar by connecting screws. The screw connection method facilitates disassembly. Simply unscrew the connecting screws and move the large and small sleeves away from the connecting structure to expose the connecting structure for easy maintenance.

[0004] However, when the aforementioned patent protects the joint between the first busbar trunking and the second busbar trunking, it requires the use of a large sleeve and a small sleeve to protect the joint. However, when the large sleeve and the small sleeve are connected to the two busbar trunkings, they need to be locked with connecting screws. During disassembly, a wrench must be used to turn the connecting screws to complete the disassembly. This results in poor flexibility in the disassembly and assembly of the large sleeve and the small sleeve, causing inconvenience in actual use. Therefore, to solve the above problems, we provide a busbar trunking joint protection device. Utility Model Content

[0005] The purpose of this utility model is to provide a busbar joint protection device to solve the problems mentioned in the background art.

[0006] The embodiments of this application adopt the following technical solutions: A busbar trunking joint protection device includes two busbar trunking bodies. A protective cover is provided on the exterior of one end of each of the two busbar trunking bodies. Two connecting seats and two connecting plates are fixedly connected to the outer surfaces of the two protective covers, respectively. A connecting clamp is fixedly connected to one side of each of the two connecting plates. One end of each connecting clamp extends into the interior of the two connecting seats. An elastic positioning element is provided on one side of each of the two protective covers. A connecting end is provided on one side of the connecting end, and a rectangular buffer pad is provided on one side of the connecting end. A rectangular groove is formed on one side of the connecting end, and the outer surface of the rectangular buffer pad is adapted to the inner wall of the rectangular groove.

[0007] Preferably, each of the two protective covers has two protective baffles fixedly connected to its inner wall. The sides of the two sets of protective baffles that are close to each other are in contact with the two sides of the two busbar trunking bodies. Each side of the two busbar trunking bodies has a limit block fixedly connected to its side, and the protective baffle is located on one side of the limit block.

[0008] Preferably, two sets of heat dissipation strips are fixedly embedded on the outer surface of both protective covers, and the heat dissipation strips are made of aluminum alloy. The ends of the two sets of heat dissipation strips that are close to each other extend into the interior of the protective cover. The upper surface of both protective covers is fixedly connected with a disassembly handle.

[0009] Preferably, the elastic positioning element includes a support cover fixedly connected to one side of the connecting seat, two springs fixedly connected to the inner wall of the support cover, a sliding plate fixedly connected to one end of the two springs, a conical positioning groove on one side of the connecting plate, one end of the sliding plate extending into the interior of the conical positioning groove, and the outer surface of one end of the sliding plate in close contact with the inner wall of the conical positioning groove.

[0010] Preferably, one end of the sliding plate is fixedly connected to a limiting slide plate, one end of the limiting slide plate passes through the support cover and extends to the outside of the support cover, and one end of the limiting slide plate is fixedly connected to a limiting baffle.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: I. This busbar trunking joint protection device uses the protective baffle on the inner wall of the protective cover to fit against the side of the busbar trunking body, and then uses a limiting block to complete the initial positioning to prevent installation misalignment. Subsequently, the protective covers are pushed closer to each other, and the connecting plate on the connecting plate is inserted into the connecting seat. The locking position is achieved by the elastic positioning component. The connection and sliding fixation of the two protective covers can be completed without additional tools, eliminating the dependence on tools such as wrenches. Even in complex working environments, the docking can be completed efficiently, reducing construction intensity and time costs. At the same time, the tight fit between the sliding plate and the conical positioning groove, combined with the elastic pre-tightening force of the spring, can form a stable self-locking structure to ensure the reliability of the joint protection.

[0012] 2. This busbar joint protection device pushes the protective cover to both sides and uses the conical positioning groove to squeeze the sliding plate, which compresses the spring and disengages from the positioning groove. Once the connecting plate is unrestrained, the protective cover can be quickly separated. The whole process requires no tools, is simple and quick to operate, and shortens the maintenance and disassembly time. The aluminum alloy heat dissipation strips embedded on the surface of the protective cover can quickly conduct the heat generated by the joint during operation, improving the heat dissipation effect.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-6This utility model provides a technical solution for a busbar joint protection device: The busbar trunking joint protection device includes two busbar trunking bodies 1. Each of the two busbar trunking bodies 1 has a protective cover 2 installed on the exterior of one end. The protective cover 2 is made of either flame-retardant reinforced nylon or SMC composite material. Two connecting seats 3 and two connecting plates 4 are fixedly connected to the outer surfaces of the two protective covers 2, respectively. A connecting clamp 13 is fixedly connected to one side of each of the two connecting plates 4. One end of each connecting clamp 13 extends into the interior of the two connecting seats 3. An elastic positioning element 5 is provided on one side of each of the two connecting seats 3. A connecting end 6 is provided on one side of each of the two protective covers 2, and a rectangular buffer pad 8 is provided on one side of the connecting end 6. A rectangular groove 7 is provided on one side of the connecting end 6, and the outer surface of the rectangular buffer pad 8 is adapted to the inner wall of the rectangular groove 7. Specifically, the joint protection is achieved by the two busbar trunking bodies 1 working together with the protective cover 2. The connecting end 6 of the protective cover 2 is provided with a rectangular buffer pad 8. The rectangular buffer pad 8 is adapted to the rectangular groove 7 and can absorb the vibration at the joint and form a seal to prevent dust from entering. The connecting plate 4 drives the connecting card 13 to be inserted into the connecting seat 3. With the help of the elastic positioning element 5, the two protective covers 2 are quickly positioned. Stable docking can be achieved without additional fasteners, realizing reliable protection of the busbar trunking joint and avoiding damage caused by external impact.

[0018] In this embodiment, two protective baffles 10 are fixedly connected to the inner walls of both protective covers 2. The sides of the two sets of protective baffles 10 that are close to each other are in contact with the two sides of the two busbar trunking bodies 1. Limiting blocks 9 are fixedly connected to one side of each of the two busbar trunking bodies 1. The protective baffles 10 are located on one side of the limiting blocks 9. Two sets of heat dissipation strips 12 are fixedly embedded on the outer surfaces of both protective covers 2. The heat dissipation strips 12 are made of aluminum alloy. The ends of the two sets of heat dissipation strips 12 that are close to each other extend into the interior of the protective cover 2. Disassembly handles 11 are fixedly connected to the upper surfaces of both protective covers 2. Specifically, the protective baffles 10 fit against the sides of the busbar trunking bodies 1. Combined with the limiting blocks 9 on the busbar trunking bodies 1, this ensures accurate alignment of the protective cover 2 during installation, prevents offset, and avoids detachment after connection. The aluminum alloy heat dissipation strips 12 are embedded in the protective cover 2 and extend into the interior, which can efficiently conduct the heat generated by the joint operation and avoid high temperature affecting equipment operation. The disassembly handles 11 provide convenient force points for disassembling and assembling the protective cover 2, improving operational flexibility.

[0019] In this embodiment, the elastic positioning member 5 includes a support cover 51 fixedly connected to one side of the connecting seat 3. Two springs 54 are fixedly connected to the inner wall of the support cover 51. One end of each spring 54 is fixedly connected to a sliding plate 55. A conical positioning groove 14 is provided on one side of the connecting plate 13. One end of the sliding plate 55 extends into the interior of the conical positioning groove 14, and the outer surface of one end of the sliding plate 55 is in close contact with the inner wall of the conical positioning groove 14. A limiting slide plate 52 is fixedly connected to one end of the sliding plate 55 to limit the sliding... One end of the plate 52 passes through the support cover 51 and extends to the outside of the support cover 51, and one end of the limiting slide plate 52 is fixedly connected to the limiting baffle 53; specifically, two springs 54 provide elastic support for the sliding plate 55, the sliding plate 55 is embedded in the conical positioning groove 14 of the connecting plate 13, and the protective cover 2 is stably locked through close contact. The limiting slide plate 52 connects the sliding plate 55 and the limiting baffle 53, and plays the role of limiting the sliding plate 55 to avoid the phenomenon of excessive slippage force of the sliding plate 55.

[0020] Working principle: When protecting the joints of the two busbar trunking bodies 1, firstly, two protective covers 2 are respectively fitted onto the outside of the joint ends of the two busbar trunking bodies 1. This allows the protective covers 2 to fit against the sides of the busbar trunking bodies 1 through the protective baffles 10 on the inner wall. The limiting blocks 9 on the busbar trunking bodies 1 achieve initial positioning of the protective covers 2, preventing displacement during installation. Then, the two protective covers 2 are pushed closer to each other until the connecting plate 13 on the connecting plate 4 is gradually inserted into the connecting seat 3. At this time, the side of the connecting plate 13... The end of the sliding plate 55 in the elastic positioning member 5 is squeezed, which forces the sliding plate 55 to compress the two springs 54 in the support cover 51 and slide inward. When the conical positioning groove 14 on the connecting plate 13 moves to align with the sliding plate 55, the spring 54 releases its elastic potential energy and pushes one end of the sliding plate 55 into the conical positioning groove 14. Through the close contact between the sliding plate 55 and the conical positioning groove 14, the quick connection and positioning of the two protective covers 2 are completed. The busbar joint can be stably protected without the need for additional connecting screws.

[0021] When disassembly and maintenance are required, the two protective covers 2 are pushed to opposite sides, which causes the tapered positioning groove 14 on the side of the connecting plate 13 to press the end of the sliding plate 55 in the elastic positioning member 5 until the sliding plate 55 is disengaged from the tapered positioning groove 14 and the spring 54 is compressed. At this time, the connecting plate 13 loses its positioning constraint, which allows the two protective covers 2 to separate to both sides, making it easy to disassemble and maintain them.
