Description

Technical Field

[0001] This utility model relates to the field of busbar connection protection technology, and in particular to a fast busbar connection protection component. Background Technology

[0002] In the field of electrical engineering, busbars, as key components for power transmission and distribution, play a crucial role in the reliable operation of the entire electrical system due to the stability of their connections and the ease of their installation. With the continuous expansion of electrical systems and the increasing demands for construction efficiency, traditional busbar connection methods have gradually revealed numerous problems, making it difficult to meet the needs of modern electrical engineering.

[0003] Currently, most busbar connection methods on the market rely on traditional bolt fastening structures. During installation, installers need to use wrenches and other tools to sequentially pass multiple bolts through the mounting holes on the busbars and connecting components, then tighten them one by one to achieve the connection between the busbars. This installation method has significant drawbacks. First, the installation steps are cumbersome, requiring a significant amount of time and manpower. Especially in large-scale electrical installation projects, the numerous bolt tightening operations can significantly extend the construction period and increase construction costs. Second, it is difficult to precisely control the tightening force of the bolts during installation. If the tightening torque is too high, it may damage the bolts or the mounting holes of the busbars; if the tightening torque is too low, the stability of the busbar connection cannot be guaranteed, and the connection may loosen due to vibration, external forces, or other factors during use, thus affecting the normal operation of the power system and potentially even causing safety accidents.

[0004] Meanwhile, during the operation of electrical systems, busbar connections frequently need to be disassembled and reinstalled due to equipment maintenance, upgrades, or replacements. Traditional bolt-fastened structures also require tools to loosen each bolt individually during disassembly, a complex and time-consuming process. Furthermore, frequent disassembly and installation can lead to wear on the bolts and mounting holes, further affecting connection stability. In addition, if bolts are lost or damaged during disassembly, additional time and costs are required to find or replace them, causing significant inconvenience to electrical system maintenance. Therefore, we provide a quick-connect busbar protection component. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a quick busbar connection protection component, which more accurately solves the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution:

[0007] The utility model proposes a quick busbar connection protection component, including a busbar body and a protection head. A plug-in block is fixedly installed at the end of the protection head, and a limit stop frame is fixedly connected to the inner wall of the busbar body to prevent the plug-in block from being inserted excessively.

[0008] A limiting mechanism is connected between the main body of the busbar and the rectangular through groove;

[0009] The limiting mechanism includes a rectangular through groove on the side of the busbar body and a sliding groove on the side of the plug-in block. A sliding limiting block is slidably connected to the inner wall of the sliding groove, and one end of the sliding limiting block is designed in an arc shape. A reciprocating structure is connected between the sliding groove and the sliding limiting block.

[0010] Furthermore, the reciprocating structure includes a rectangular groove formed on the inner wall of the sliding groove, a horizontal fixing rod fixedly connected between the two end walls of the rectangular groove, a spring sleeved around the horizontal fixing rod, and a movable sleeve block slidably sleeved around the horizontal fixing rod.

[0011] Furthermore, electrical mating plates are installed on the upper and lower end surfaces of the protective head, and torque screws are threaded onto the surface of the electrical mating plates for fixing the electrical mating plates to the protective head.

[0012] Furthermore, the movable sleeve is slidably connected to the inner wall of the rectangular groove, and the opposing surfaces of the two movable sleeves are fixedly connected to the two side surfaces of one sliding limiting block.

[0013] Furthermore, one end of the sliding limit block is inserted into the inner wall of the rectangular through groove, and the opening size of the rectangular through groove is compatible with the design size of the sliding limit block.

[0014] Furthermore, one end of the spring is fixedly connected to the end wall of the rectangular groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.

[0015] The beneficial effects of this utility model are:

[0016] This invention achieves rapid connection through a unique structural design. During installation, simply insert the plug-in block at the end of the protective head into the busbar body. During insertion, the sliding limit block automatically retracts under the action of the reciprocating structure. Once the plug-in block is fully inserted, the sliding limit block automatically pops out and engages with the rectangular through slot, completing the limiting and fixing process. The entire process requires no additional tools or complex alignment and tightening operations. This design greatly simplifies the installation process, reduces installation time and manpower, and significantly improves work efficiency. It is particularly suitable for large-scale electrical engineering projects with high installation speed requirements, effectively reducing construction costs for enterprises.

[0017] This invention ensures connection reliability through multiple stabilization designs. First, the limiting frame on the inner wall of the busbar body prevents over-insertion of the plug-in block, avoiding structural damage or connection instability caused by over-insertion. Second, the sliding limiting block in the limiting mechanism is adapted to the size of the rectangular through slot. When the sliding limiting block is engaged in the rectangular through slot, it effectively prevents relative movement between the protective head and the busbar body, ensuring the stability of the connection. Furthermore, the electrical connection piece is securely installed on the protective head with a tightening screw, ensuring the reliability of the electrical connection. This fast and stable connection method improves installation efficiency while ensuring the normal operation of the busbar connection protection components in the electrical system, saving enterprises significant time and labor costs.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0023] Example

[0024] like Figs. 1-3 As shown in the figure, an embodiment of the present invention provides a quick busbar connection protection component, including a busbar body 1 and a protection head 2. A plug-in block 5 is fixedly installed at the end of the protection head 2, and a limiting frame 6 is fixedly connected to the inner wall of the busbar body 1. Simultaneously, a limiting mechanism is provided between the busbar body 1 and the rectangular through groove 7. The limiting mechanism is specifically constructed as follows: a rectangular through groove 7 is opened on the side of the busbar body 1, a sliding groove 8 is opened on the side of the plug-in block 5, a sliding limiting block 13 is slidably connected to the inner wall of the sliding groove 8, and one end of the sliding limiting block 13 is designed in an arc shape. A reciprocating structure connects the sliding groove 8 and the sliding limiting block 13.

[0025] In this process, when connecting the protective head 2 and the busbar body 1, the plug-in block 5 at the end of the protective head 2 is inserted into the busbar body 1. The limiting frame 6 prevents the plug-in block 5 from being over-inserted. When the plug-in block 5 is inserted into the appropriate position, under the action of the reciprocating structure, the sliding limiting block 13 can automatically engage with the rectangular through slot 7, realizing the quick connection and fixation of the protective head 2 and the busbar body 1. The operation is simple and convenient, greatly improving the installation efficiency of the busbar connection protection components.

[0026] Furthermore, a rectangular groove 9 is formed on the inner wall of the sliding groove 8, and a horizontal fixing rod 10 is fixedly connected between the two end walls of the rectangular groove 9. A spring 11 is sleeved on the outer periphery of the horizontal fixing rod 10, and a movable sleeve block 12 is slidably sleeved on the outer periphery of the horizontal fixing rod 10.

[0027] During the insertion of the plug-in block 5 into the busbar body 1, the arc-shaped end of the sliding limit block 13 is compressed, pushing the movable sleeve block 12 to slide on the horizontal fixing rod 10 and compressing the spring 11, causing the sliding limit block 13 to retract into the sliding groove 8, ensuring that the plug-in block 5 can be smoothly inserted. When the plug-in block 5 reaches the appropriate position and the sliding limit block 13 corresponds to the rectangular through groove 7, under the elastic force of the spring 11, the movable sleeve block 12 is pushed to slide in the opposite direction, thereby driving the sliding limit block 13 to insert into the rectangular through groove 7, achieving automatic limiting and fixing without additional operation, further simplifying the installation process.

[0028] Furthermore, electrical mating pieces 3 are installed on the upper and lower surfaces of the protective head 2, and tightening screws 4 are threaded onto the surface of the electrical mating pieces 3.

[0029] The electrical connection piece 3 can be firmly fixed on the protective head 2 by the tightening screw 4, ensuring good electrical and mechanical connection stability between the electrical connection piece 3 and the protective head 2, ensuring the normal conductivity function of the busbar connection protection component in the electrical system, and facilitating the installation, disassembly and maintenance of the electrical connection piece 3.

[0030] Furthermore, the movable sleeve 12 is slidably connected to the inner wall of the rectangular groove 9, and the opposite surfaces of the two movable sleeves 12 are fixedly connected to the two side surfaces of a sliding limiting block 13.

[0031] The movable sleeve 12 can slide stably within the rectangular groove 9. When the sliding limit block 13 is squeezed or subjected to the elastic force of the spring 11, the force can be accurately transmitted to the movable sleeve 12 through the fixed connection with the movable sleeve 12, so that the movable sleeve 12 slides on the horizontal bar 10, thereby realizing the reciprocating motion of the sliding limit block 13, ensuring that the limiting mechanism can work normally, and realizing the reliable connection and disassembly of the protective head 2 and the busbar body 1.

[0032] Furthermore, one end of the sliding limit block 13 is inserted into the inner wall of the rectangular through groove 7, and the opening size of the rectangular through groove 7 is compatible with the design size of the sliding limit block 13.

[0033] When the plug-in block 5 is inserted into place, the sliding limit block 13 is inserted into the rectangular through slot 7 under the action of the reciprocating structure. Due to the size fit, the sliding limit block 13 can be tightly locked in the rectangular through slot 7, effectively preventing relative movement between the protection head 2 and the busbar body 1, ensuring the stability and reliability of the connection, and avoiding the normal function of the busbar connection protection component due to loose connection during use.

[0034] Furthermore, one end of the spring 11 is fixedly connected to the end wall of the rectangular groove 9, and the other end of the spring 11 is fixedly connected to one end surface of the movable sleeve 12.

[0035] When the sliding limit block 13 is compressed, causing the movable sleeve 12 to slide and compress the spring 11, the spring 11 stores elastic potential energy. When the sliding limit block 13 reaches the appropriate position, the spring 11 releases its elastic potential energy, pushing the movable sleeve 12 to slide in the opposite direction, thereby causing the sliding limit block 13 to insert into the rectangular through slot 7, achieving automatic limiting. This connection method of the spring 11 provides a stable power source for the reciprocating motion of the sliding limit block 13, ensuring that the limiting mechanism can work normally and reliably, and improving the performance of the quick busbar connection protection component.
