A bolt is arranged at the center of the pressing plate. Fixing components are arranged on both sides of the pressing plate.

[0006] Preferably, threaded holes are opened at the top and bottom of the connecting piece.

[0007] Preferably, square jacks are opened at the top and bottom of the connecting piece.

[0008] Preferably, the limiting component includes a limiting plate. The limiting plate is arranged at the top and bottom of the connecting piece. A limiting block is arranged inside the limiting plate.

[0009] Preferably, a limiting groove matching the limiting block is opened inside the limiting plate.

[0010] Preferably, a through hole is opened at the center of the pressing plate.

[0011] Preferably, the fixing component includes a support plate fixedly arranged on both sides of the pressing plate. Both sides of the support plate are connected to the outer wall of the limit block, and a clamping plate is arranged at the bottom end of the support plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model is provided with a busbar connection device. Through the cooperation of the connecting piece, the pressing plate and the bolt, the connecting plate and the connecting piece can be firmly fixed, ensuring the tight and reliable connection between the busbars, preventing loosening or separation during use, improving the connection stability. The limiting plate and the limiting block in the limiting component can limit the support plate, further enhancing the connection firmness. When the support plate is pressed down, the limiting block slides in the limiting groove of the limiting plate, ensuring the accurate movement track of the support plate, thereby ensuring the overall stability of the connection device. A bolt is arranged at the center of the pressing plate, and threaded holes are opened at the top and bottom ends of the connecting piece. During installation, fixation can be achieved simply by tightening the bolt, and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a busbar connection device, including a busbar 1 and a connecting plate 2. The connecting plate 2 is arranged inside the busbar 1, and a connecting piece 3 is arranged on the outer wall of the connecting plate 2. The connecting piece 3 is used to connect the busbar 1, and a limiting component is arranged on the outer wall of the connecting piece 3. Pressure plates 6 are arranged at both the top and bottom of the connecting piece 3. The pressure plates 6 can fix the connecting plate 2 and the connecting piece 3 through the cooperation of bolts 7. A bolt 7 is arranged at the center of the pressure plate 6, and fixing components are arranged on both sides of the pressure plate 6. Threaded holes are opened at both the top and bottom of the connecting piece 3, and square jacks are opened at both the top and bottom of the connecting piece 3.

[0020] The limiting component includes limiting plates 4 arranged at both the top and bottom of the connecting piece 3. The limiting plates 4 can limit the support plate 8 through the limiting blocks 5. A limiting block 5 is arranged inside the limiting plate 4. The limiting block 5 slides inside the limiting plate 4 to limit the support plate 8 when it is pressed down. A limiting groove matching the limiting block 5 is opened inside the limiting plate 4, and a through hole is opened at the center of the pressure plate 6.

[0021] The fixing component includes support plates 8 fixedly arranged on both sides of the pressure plate 6, and both sides of the support plates 8 are connected to the outer wall of the limiting blocks 5. When the support plates 8 drive the clamping plates 9 to move downward, the clamping plates 9 can be inserted into the connecting plate 8 for fixation. A clamping plate 9 is arranged at the bottom of the support plate 8.

[0022] Working principle: When the busbar connection device starts to be used, the user first drives the connecting plate 8 to insert into the inside of the connecting piece 3 from both sides of the busbar 1, and then the user inserts the support plate 8 into the inside of the limiting plate 4 through the limiting block 5 and moves it downward. When the pressure plate 6 is completely attached to the surface of the connecting piece 3, the clamping plate 9 just inserts into the connecting plate 2. Then, when the pressure plate 6 drives the support plate 8 and the limiting block 5 to move downward, the pressure plate 6 can be limited. Then, when the clamping plate 9 is completely inserted into the connecting plate 2, the user inserts the bolt 7 downward through the center of the pressure plate 6 and rotates it into the inside of the connecting piece 3 to fix the pressure plate 6. By fixing the pressure plate 6, the connecting plate 2 and the connecting piece 3 are fixedly connected indirectly through the clamping plate 9, which can effectively prevent the traditional connector from having a gap between the connecting plate 2 and the connector due to vibration after connection, thus affecting the conductive effect.

[0023] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
