[0001] The utility model belongs to the field of busbar connection, and particularly relates to a quick-connect busbar. Background Art

[0002] Busbars, also known as busbar rows or busbar wires, are conductive materials on power distribution equipment. Their main function is to act as conductors. They usually refer to the connection parts between the main switch in the electrical cabinet and the switches in each branch circuit in the power supply system. They can be copper bars or aluminum bars, and their surfaces are insulated. Busbars are widely used in various power distribution systems such as switchboards, switchgear, and distribution boards, and are key components of power infrastructure.

[0003] Chinese Utility Model Patent CN219267906U discloses a busbar that can be quickly connected, including a first busbar and a second busbar. One end of the first busbar is attached and perpendicularly connected to one end of the second busbar. A fixed clamping sleeve plate is sleeved outside the connection of the first busbar and the second busbar, and a movable clamping plate group is movably sleeved inside the fixed clamping sleeve plate. A composite drive shaft member is meshed and driven inside the front-end structure of the movable clamping plate group. After the fixed clamping sleeve plate, the movable clamping plate group, the composite drive shaft member, and the locking connection member are assembled together, a quick-installation structure is formed. After subsequent comprehensive assembly with the second busbar and the first busbar, the connection between the first busbar and the second busbar can be synchronously clamped and fixed without drilling holes in the first busbar and the second busbar, thereby realizing convenient processing without drilling holes while the first busbar and the second busbar in the surface clamping and fixing state are deformed;

[0025] In order to make the above-mentioned objects, features, and advantages of this utility model more obvious and understandable, the following detailed description of the specific embodiments of this utility model will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, numerous specific details are set forth to provide a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments. The present utility model provides the following embodiments.

[0028] As shown by Figure 1 , Figure 2 and Figure 3 , a quick-connecting busbar includes a first busbar 1, a limiting frame 2, a pressing plate 3, and a second busbar 4. The limiting frame 2 is arranged on the side of the first busbar 1. The pressing plate 3 is slidably installed inside the limiting frame 2, and the second busbar 4 is slidably installed inside the limiting frame 2. A lifting mechanism 5 is fixedly installed inside the limiting frame 2. The lifting mechanism 5 includes a lifting groove 51, a lead screw 52, a guide rod 53, a moving end 54, and a rotating assembly 55. The lifting groove 51 is opened inside the limiting frame 2. The lead screw 52 is rotatably installed inside the lifting groove 51. The guide rod 53 is fixedly installed inside the lifting groove 51. The lead screw 52 and the guide rod 53 are parallel in position. The moving end 54 is threadedly engaged with the outside of the lead screw 52. The moving end 54 is slidably connected to the guide rod 53. The side of the moving end 54 is fixedly connected to the pressing plate 3. The rotating assembly 55 is rotatably installed on the upper surface of the limiting frame 2. The end of the rotating assembly 55 is fixedly connected to the end of the lead screw 52. During use, the first busbar 1 and the second busbar 4 to be docked are respectively placed on both sides of the limiting frame 2. At this time, according to the connection angle between the first busbar 1 and the second busbar 4, the position where the second busbar 4 is inserted into the limiting frame 2 is adjusted. When the second busbar 4 and the first busbar 1 are inserted into the limiting frame 2, it is ensured that the connection parts of the second busbar 4 and the first busbar 1 are in contact. By using the lifting mechanism 5, the connection between the second busbar 4 and the first busbar 1 is squeezed. By rotating the rotating assembly 55, the lead screw 52 rotates inside the lifting groove 51. The moving end 54 is threadedly engaged with the lead screw 52. The moving end 54 will vertically lift along the outer wall of the guide rod 53, driving the pressing plate 3 to move synchronously. During the downward pressing of the pressing plate 3, the connection components of the second busbar 4 and the first busbar 1 at the bottom are squeezed, completing the quick connection between the first busbar 1 and the second busbar 4.

[0029] As shown in the attached Figure 3As shown, in this embodiment, the rotating assembly 55 includes a rotating block 551, a protective cover 552, and a mating groove 553. The rotating block 551 is rotatably installed on the upper surface of the limiting frame 2. The protective cover 552 is sleeved outside the rotating block 551. The mating grooves 553 are equidistantly formed on the outside of the protective cover 552. During use, by sleeving the protective cover 552 on the outer surface of the rotating block 551 and utilizing the insulating property of the protective cover 552 itself, the safety during equipment use is enhanced. The formation of the mating grooves 553 facilitates better fitting of the user's hand to the outer surface of the protective cover 552, making the rotation of the rotating block 551 more stable subsequently.

[0030] As shown in the attached Figure 4 As shown, in this embodiment, the pressing plate 3 includes a top plate 31, a baffle 32, and a limiting post 33. The top plate 31 is slidably installed inside the limiting frame 2. The limiting posts 33 are symmetrically and fixedly installed at the bottom end of the top plate 31. The baffle 32 is fixedly installed at the bottom end of the top plate 31 and is installed on the side away from the limiting posts 33. During use, through the limitation of the distance between the baffle 32 and the limiting posts 33, the busbars entering the bottom end of the top plate 31 are horizontally butted. The distance between the limiting posts 33 allows the second busbar 4 to be inserted between the limiting posts 33, making the second busbar 4 perpendicular to the first busbar 1, which can assist in the perpendicular butting between the busbars.

[0031] As shown in the attached Figure 4 As shown, in this embodiment, the pressing plate 3 further includes a raised block 34. The raised blocks 34 are equidistantly and fixedly installed on the lower surface of the top plate 31. During use, through the installation of the raised blocks 34, when the top plate 31 moves downward, it can better press the surface of the second busbar 4, enhancing the friction force when the top plate 31 is connected to the second busbar 4.

[0032] As shown in the attached Figure 5 As shown, in this embodiment, the device further includes a pressing mechanism 6. The second busbar 4 and the first busbar 1 are butted in the same direction through the pressing mechanism 6. The pressing mechanism 6 includes a pressing groove 61, a pushing plate 62, and a rotating screw 63. The pressing groove 61 is formed inside the limiting frame 2. The pushing plate 62 is slidably installed inside the pressing groove 61. The rotating screw 63 is threadedly installed outside the limiting frame 2 and passes through the inside of the limiting frame 2 and extends into the pressing groove 61. The bottom end of the rotating screw 63 is rotatably connected to the pushing plate 62. During use, by inserting the second busbar 4 and the first busbar 1 into the limiting frame 2 in the same horizontal and same direction, then rotating the rotating screw 63, the rotating screw 63 continuously extends into the limiting frame 2 by virtue of the thread on its outside, driving the pushing plate 62 to synchronously press the second busbar 4 and the first busbar 1 on the side, completing the butting of the first busbar 1 and the second busbar 4.

[0033] As shown in the attached Figure 5As shown, in this embodiment, the extrusion mechanism 6 further includes a limit rod 64 and a limit groove 65. The limit rod 64 is symmetrically and fixedly installed inside the extrusion groove 61. A limit groove 65 is formed in the push plate 62 corresponding to the limit rod 64. The limit rod 64 is slidably connected to the limit groove 65. During use, through the cooperation of the limit rod 64 and the limit groove 65, the movement trajectory of the push plate 62 itself can be limited, preventing the push plate 62 from rotating synchronously with the rotation of the rotating screw 63, ensuring the stability of the push plate 62 during use.

[0034] As shown in the appended Figure 6 As shown, in this embodiment, the first busbar 1 includes a busbar main body 11, a protective sleeve 12, and a connection end 13. The busbar main body 11 is arranged on the side of the limit frame 2. Connection ends 13 are symmetrically arranged inside the busbar main body 11. The protective sleeve 12 is sleeved on the outer surface of the busbar main body 11. During use, the connection end 13 is used to connect circuit lines, and the installation of the protective sleeve 12 protects the outer surface of the busbar main body 11 to form an insulating layer.

[0035] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
