Detailed Implementation

[0028] To address the problem that traditional busbar installation structures are typically fixed and difficult to adjust flexibly according to different busbar sizes and installation scenarios, this utility model provides a busbar installation structure and its combined switchgear. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-8 This utility model provides a busbar installation structure, including a first clamp 1 and a second clamp 2, which are connected by an adjusting bolt 3.

[0030] Multiple sets of connecting grooves 4 are provided on opposite sides of the first clamp 1 and the second clamp 2. An inner liner 5 is provided in the multiple sets of connecting grooves 4. Limiting wings 52 are provided on both sides of the inner liner 5. Arc-shaped connecting angles 53 are provided on the upper and lower parts of the limiting wings 52. The inner liner 5 moves linearly into the connecting groove 4 through the limiting wings 52.

[0031] The inner liner 5 is connected to the first clamp 1 and the second clamp 2 via a positioning assembly 6. The positioning assembly 6 includes a content groove 61 located at the tail end of the inner liner 5, and a strip-shaped positioning plate 62 slidably connected to the content groove 61. The upper part of the positioning plate 62 is arc-shaped, and the positioning plate 62 moves linearly inside the content groove 61 via a baffle 63. Multiple sets of positioning springs 64 are arranged linearly inside the content groove 61, and the positioning springs 64 are located directly below the baffle 63, allowing the positioning plate 62 to move elastically within the content groove 61 via the baffle 63. A slot 51 for busbar connection is provided in the inner liner 5.

[0032] The first clamp 1 and the second clamp 2 are located at the tail end of the connecting groove 4 and are connected to a clamping plate 8 via a rotating shaft 7. The lower part of the clamping plate 8 has a concave groove 81 for connecting the positioning plate 62, and one side of the concave groove 81 is arc-shaped. The front end of the clamping plate 8 is provided with a fastening plate 9, and the lower part of the fastening plate 9 is provided with a buckle 91.

[0033] The end of the connecting groove 4 is provided with a slot 41 that cooperates with the buckle 91.

[0034] A modular switchgear includes a busbar mounting structure.

[0035] The working principle of the busbar mounting structure and its combined switchgear provided by this utility model is as follows:

[0036] According to the actual size and specifications of the busbar to be installed, select the appropriate inner liner 5. The slot 51 at the inner liner 5 must be compatible with the size and specifications of the busbar to be installed. Then, snap the buckle 91 of the fastening plate 9 into the slot 41 to fix the fastening plate 9.

[0037] The inner liner 5 is then moved linearly along the connecting groove 4 via the limiting wings 52 on both sides, and embedded into the connecting groove 4 opposite to the first clamp 1 and the second clamp 2. The arc-shaped connecting angles 53 on the upper and lower parts of the limiting wings 52 can guide the inner liner 5 smoothly into the connecting groove 4 to a certain extent. At the same time, after the inner liner 5 is installed in place, it plays a preliminary limiting role, preventing the inner liner 5 from excessive shaking or displacement in the connecting groove 4.

[0038] When the inner liner 5 is inserted into the connecting groove 4, the strip-shaped positioning plate 62 at its tail end moves to the lower part of the clamping plate 8. The clamping plate 8 squeezes the positioning plate 62, and the positioning plate 62 moves linearly inside the content groove 61 under the force of the baffle 63, squeezing the positioning spring 64 inside the content groove 61. The positioning spring 64 is compressed under the force.

[0039] When the inner liner 5 is connected to the positioning plate 62 and moves to the concave groove 81 side of the clamping plate 8, the positioning spring 64 generates a reverse elastic force, thereby pressing the positioning plate 62 tightly against the concave groove 81 of the clamping plate 8, realizing a reliable connection and fixation between the inner liner 5 and the first clamping seat 1 and the second clamping seat 2, and preventing the inner liner 5 from loosening or falling off in the connecting groove 4.

[0040] Then, the relative position and spacing of the first clamp 1 and the second clamp 2 are adjusted by adjusting bolt 3 to meet the installation requirements of the busbar.

[0041] When replacing, the buckle 91 is removed from the slot 41 by the fastening plate 9, and the clamping plate 8 is rotated by the rotating shaft 7. The clamping plate 8 drives the lower concave groove 81 to rotate, thereby squeezing the positioning plate 62 out of the concave groove 81 until the positioning plate 62 is stored in the inner groove 61. The connection between the inner liner 5 and the clamping plate 8 is released, and the inner liner 5 can be removed from the first clamping seat 1 and the second clamping seat 2 for disassembly and replacement.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
