Description

Technical Field

[0001] This utility model relates to the field of busbar trunking application technology, and in particular to a busbar trunking system with a positioning connection structure. Background Technology

[0002] Busbar trunking is a type of power distribution equipment used in power systems to transmit large currents. It mainly consists of conductors, insulation materials, a shell, and accessories. Its function is similar to that of a cable, but it has higher current carrying capacity, better mechanical strength, and more flexible installation methods. It is widely used in buildings, industries, data centers, and other scenarios.

[0003] Traditional busbar trunking systems rely on bolt fastening or plug-in connections for connection, which has the following drawbacks: conductor misalignment is easy, leading to increased contact resistance or short circuit risk, resulting in low positioning accuracy, requiring manual alignment, which is time-consuming and labor-intensive, especially in dense spaces, making operation difficult and resulting in low installation efficiency. Therefore, this utility model proposes a busbar trunking system with a positioning connection structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a busbar trunking system with a positioning connection structure. By setting a pre-positioning frame on the end face of the busbar trunking, when two busbar trunkings are spliced ​​at the end face, they can be quickly inserted and fixed with the connecting components, which improves the rapid positioning effect during installation and ensures a deep match between the mechanical structure and functional requirements.

[0005] To solve the above-mentioned technical problems, the present invention provides a busbar trunking system with a positioning connection structure, including adjacent busbar trunking bodies. Positioning frames are bolted to the end faces of the adjacent busbar trunking bodies, and connecting components are engaged on the opposite faces of the two positioning frames. Reinforcing screws are provided through the two positioning frames near their corners.

[0006] The present invention is further configured such that: the positioning frame includes a mounting frame bolted to the end face of the busbar trunking body shell; the inner wall of the mounting frame is symmetrically provided with bent portions; the mounting frame is bolted to the side wall of the busbar trunking body shell through the bent portions; connection holes are provided at the corners of the mounting frame, and multiple reinforcing screws pass through the connection holes respectively; and connecting guide plates are symmetrically fixedly connected to the side wall of the mounting frame away from the bent portions.

[0007] The above technical solution allows the positioning frame to be stably installed on the end face of the busbar trunking body using the bending part, and the connecting hole allows for further reinforcement with reinforcing screws in the later stage, ensuring the stability of the busbar trunking body during installation and use.

[0008] The present invention is further configured such that: the connecting assembly includes a connecting frame sleeved on the end face of the connecting guide plate, a center plate is fixedly connected to the center of the connecting frame, a plurality of protective cylinders are evenly provided inside the center plate, a spring is provided through the interior of each of the plurality of protective cylinders, and a pressing block is symmetrically engaged with the end face of each of the plurality of springs.

[0009] The above technical solution utilizes springs to movably connect the compression blocks at both ends to the interior of the center plate, thereby enabling the connecting guide plates inserted on both sides to stably press against them, thus fixing the connecting guide plates stably inside the connecting frame and achieving a firm connection between the end faces of the two busbar trunking bodies.

[0010] The present invention is further configured such that: sliders are symmetrically fixedly connected to the inner wall of the connecting frame near the top and bottom positions, and the two sets of sliders are respectively slidably connected to guide grooves opened at corresponding positions on the outer wall of the connecting guide plates on both sides.

[0011] The above technical solution facilitates the stable insertion of the connector into the guide groove using a slider during installation, thus improving the ease of installation.

[0012] The present invention is further configured such that: the inner wall of the connecting frame is symmetrically fixedly connected with limiting blocks near the middle of the side wall, and the limiting blocks are respectively engaged with the limiting grooves opened near the end face of the adjacent connecting guide plates.

[0013] The above technical solution facilitates the positioning and fixing of the connecting frame when it is sleeved on the outer wall of the connecting guide plate using the limiting block and limiting groove.

[0014] The present invention is further configured such that: the connecting frame is respectively sleeved on the end faces of the two connecting guide plates, and the end faces of the two connecting guide plates are respectively pressed against the two pressing blocks.

[0015] The above technical solution enables the two connecting guide plates to stably press and clamp the internal extrusion block when inserted into the connecting frame, thereby allowing the connecting guide plates on both sides to be stably installed inside the connecting frame.

[0016] The present invention is further configured such that the outer walls of both extrusion blocks are slidably connected to the inner wall of the connecting frame.

[0017] The above technical solution facilitates stable sliding within the connecting frame when the extrusion block inside the connecting frame is pressed, thereby improving the pressing effect after installation.

[0018] The beneficial effects of this utility model are as follows:

[0019] The present invention proposes a busbar trunking system with a positioning connection structure.

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] like Figures 1-4As shown, a busbar trunking system with a positioning connection structure includes adjacent busbar trunking bodies 1. Positioning frames 2 are bolted to the end faces of adjacent busbar trunking bodies 1. The positioning frame 2 includes a mounting frame 21 bolted to the end face of the outer shell of the busbar trunking body 1. The inner wall of the mounting frame 21 is symmetrically provided with bending portions 22. The mounting frame 21 is bolted to the side wall of the outer shell of the busbar trunking body 1 through the bending portions 22. Connection holes 23 are provided at the corners of the mounting frame 21, and multiple reinforcing screws 4 pass through the connection holes 23. Connecting guide plates 24 are symmetrically fixed to the side wall of the mounting frame 21 away from the bending portions 22. The bending portions 22 can stably install the positioning frame 2 on the end face of the busbar trunking body 1, and the connection holes 23 can facilitate further reinforcement with reinforcing screws 4 in the later stage, ensuring the firmness of the busbar trunking body 1 during installation and use. The opposite faces of the two positioning frames 2 are engaged with connecting components 3, and reinforcing screws 4 are provided through the corners of the two positioning frames 2.

[0029] like Figure 5 and Figure 6As shown, the connecting assembly 3 includes a connecting frame 31 sleeved on the end face of the connecting guide plate 24. Slider 32s are symmetrically fixed to the inner wall of the connecting frame 31 near the top and bottom. Two sets of sliders 32 are slidably connected to guide grooves 25 corresponding to the outer walls of the connecting guide plates 24 on both sides. This facilitates the stable insertion of the connecting frame 31 into the guide grooves 25 during installation, improving ease of installation. A center plate 34 is fixedly connected to the center of the connecting frame 31. Limiting blocks 33 are symmetrically fixed to the inner wall of the connecting frame 31 near the middle of the side wall. These limiting blocks 33 engage with limiting grooves 26 near the end face of adjacent connecting guide plates 24, allowing the connecting frame 31 to be positioned and fixed using the limiting blocks 33 and limiting grooves 26 when sleeved on the outer wall of the connecting guide plate 24. Multiple protective cylinders 35 are evenly distributed inside the center plate 34, and springs 36 penetrate the interior of each protective cylinder 35. Multiple springs 36 are symmetrically engaged with pressing blocks 37 on their end faces. The pressing blocks 37 at both ends are movably connected to the inside of the center plate 34 by the springs 36, so that the connecting guide plates 24 inserted on both sides can be stably pressed against them, and the connecting guide plates 24 are stably fixed inside the connecting frame 31, thereby achieving a firm connection between the end faces of the two busbar trunking bodies 1. The connecting frame 31 is respectively sleeved on the end faces of the two connecting guide plates 24, and the end faces of the two connecting guide plates 24 are respectively pressed against the two pressing blocks 37. This allows the two connecting guide plates 24 to stably press against the pressing blocks 37 inside the connecting frame 31 when they are inserted into it, so that the connecting guide plates 24 on both sides can be stably installed inside the connecting frame 31. The outer walls of the two pressing blocks 37 are slidably connected to the inner wall of the connecting frame 31, so that they can slide stably inside the connecting frame 31 when pressing against the pressing blocks 37 inside the connecting frame 31, thereby improving the pressing effect after installation.

[0030] In use, the connecting component 3 is first fitted onto the connecting guide plate 24 on the end face of the pre-fixed busbar trunking body 1 via the connecting frame 31. Then, another busbar trunking body 1 is inserted into the connecting frame 31 via the connecting guide plate 24 on the positioning frame 2, and pushed in further. This causes the slider 32 inside the connecting frame 31 to slide inside the guide groove 25 of the connecting guide plate 24 and to press the internal pressing block 37. The internal spring 36 then drives another pressing block 37 to press the pre-fixed connecting guide plate 24. During the continuous pressing process, the limiting block 33 on the connecting frame 31 slides into the limiting groove 26 on the two connecting guide plates 24, thereby connecting and fixing the two connecting guide plates 24. Finally, the four external reinforcing screws 4 are installed at the corners of the mounting frame 21 for reinforcement, realizing the quick connection and fixing of the two busbar trunkings.
