Description

Technical Field

[0001] The present application relates to the technical field of power transmission busbars, and in particular to a power busbar connector. Background Art

[0002] Busbars are tools used to transmit electrical energy. Due to their large capacity and short design and construction period, they have gradually replaced cables and become the mainstream transmission tool. There are roughly two types of busbar docking, including corner connection and straight connection, and special connection devices are required at the connection points.

[0003] A Chinese patent with publication number CN113725791B discloses a connection device for a power busbar, which is suitable for a power busbar. A power busbar includes busbar 1 and busbar 2. The ends of busbar 1 and busbar 2 close to each other are both provided with grooves, and the two groove surfaces are in contact with each other and parallel. Both sides of busbar 1 and busbar 2 are provided with several groups of heat dissipation grooves. The connection device includes two groups of protective shells 1, both groups of protective shells 1 are located on the outside of busbar 1 and busbar 2, and the two groups of protective shells 1 are fixedly connected to each other.

[0004] During the use of the above technology, the angle between busbar 1 and busbar 2 is completely controlled by the design angle of the protective shell, which cannot be changed. The corner angles in the building are usually inconsistent, which makes it unable to adapt to buildings with more corners of different sizes, and there are shortcomings. Utility Model Content

[0005] In order to improve the problem that the busbar connecting device cannot adapt to different corners in a building, the present application provides a power busbar connector.

[0006] The power busbar connector provided in this application adopts the following technical solution:

[0007] A power busbar connector comprises a first connecting tube and a second connecting tube of identical structure, the first connecting tube being rotatably connected to the second connecting tube, a conductive plate being provided on the first connecting tube, the conductive plate on the first connecting tube being rotatably connected to the conductive plate on the second connecting tube, the rotation center of the conductive plate being coaxially arranged with the rotation center of the first connecting tube, a fixing assembly being provided on the first connecting tube, the fixing assembly being used to fix the busbar on the conductive plate, an angle control assembly being provided between the first connecting tube and the second connecting tube, the angle control assembly being used to control the angle between the first connecting tube and the second connecting tube.

[0008] By adopting the above technical solution, construction workers fix the busbar on the conductive plate through a fixing component, and then rotate and change the angle between the first connecting tube and the second connecting tube to adapt to the corners in the building. During this process, the conductive plate on the first connecting tube and the conductive plate on the second connecting tube rotate at the same angle, and the current flow from the first connecting tube to the second connecting tube is realized. Finally, the angle between the first connecting tube and the second connecting tube is fixed by the angle control component.

[0009] Optionally, the fixing assembly includes a spring plate arranged on the conductive plate, a clamping plate is arranged on the spring plate, a clamping bolt is bolted to the first connecting tube, the clamping plate is rotatably engaged with the end of the clamping bolt, and the clamping bolt is used to clamp the clamping plate onto the busbar.

[0010] By adopting the above technical solution, after the busbar is inserted into the first connecting tube, the construction personnel rotate the tightening bolt, and the tightening bolt pushes the tightening plate against the busbar. During this process, the spring plate bends and deforms, and at the same time, the spring plate connects the current path between the busbar and the conductive plate.

[0011] Optionally, a plurality of anti-slip cones are provided on the side of the clamping plate facing away from the clamping bolt.

[0012] By adopting the above technical solution, when the clamping plate is pressed against the busbar, the tip of the anti-fall-off cone will be embedded in the busbar, thereby reducing the possibility of the busbar and the first connecting pipe falling off during the wiring process of the construction workers.

[0013] Optionally, the angle control assembly includes an angle plate arranged on the first connecting tube, the axis of the angle plate is coaxial with the rotation center of the first connecting tube, an angle rod is arranged on the angle plate to rotate around the axis of the angle plate, the end of the angle rod facing away from the angle plate is arranged on the second connecting tube, a fixing screw is bolted to the angle rod, and a plurality of fixing holes are opened on the angle plate along the circumference of its axis, and the fixing holes are threadedly engaged with the fixing screws.

[0014] By adopting the above technical solution, when the first connecting pipe and the second connecting pipe are rotated to a certain angle, the construction worker screws the fixing screw on the angle rod, and screws the fixing screw into the fixing hole on the angle plate to fix the angle between the first connecting pipe and the second connecting pipe.

[0015] Optionally, an insulating shaft is coaxially rotatably provided at the rotation center of the first connecting tube, a conductive support ring is coaxially provided on the insulating shaft, the conductive plate is rotatably provided on the conductive support ring, and the conductive support ring supports the conductive plate.

[0016] By adopting the above technical solution, when the conductive plate on the first connecting tube rotates around the conductive plate on the second connecting tube, the conductive support ring supports the conductive plate, reducing the possibility of the conductive plate slipping along the axial direction of the insulating shaft, which is beneficial to improving the stability of the conductive performance of the conductive plate.

[0017] Optionally, an anti-loosening block is threadedly connected to the clamping bolt, and the anti-loosening block is used to tighten the first connecting pipe.

[0018] By adopting the above technical solution, the construction workers tighten the anti-loosening block, and the anti-loosening block is pressed against the first connecting pipe, thereby reducing the possibility of the busbar being loosened due to the rotation of the tightening bolt.

[0019] Optionally, an elastic bellows is provided between the first connecting pipe and the second connecting pipe, and the elastic bellows is used to seal the gap between the first connecting pipe and the second connecting pipe.

[0020] By adopting the above technical solution, the possibility of foreign matter entering the gap between the first connecting pipe and the second connecting pipe, resulting in a deterioration in the busbar current conduction effect, is reduced.

[0021] Optionally, a baffle is provided in the first connecting tube, and the baffle is used to abut against the end of the busbar.

[0022] By adopting the above technical solution, it is convenient for construction workers to quickly plug and install in place, and at the same time reduces the possibility that the busbar is removed too long, resulting in the first connecting pipe and the second connecting pipe being unable to rotate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Construction workers secure the busbar to the conductive plate using a fixing assembly. They then rotate the first and second connecting tubes to adjust the angle to accommodate the building's corners. During this process, the conductive plates on the first and second connecting tubes rotate at the same angle, enabling current flow from the first to the second tubes. Finally, the angle between the first and second tubes is fixed using the angle control assembly.

[0025] 2. When the clamping plate is pressed against the busbar, the tip of the anti-drop cone will be embedded in the busbar, thereby reducing the possibility of the busbar and the first connecting pipe falling off during the wiring process;

[0026] 3. After the first connecting pipe and the second connecting pipe are rotated to a certain angle, the construction worker screws the fixing screws on the angle rod, and screws the fixing screws into the fixing holes on the angle plate to fix the angle between the first connecting pipe and the second connecting pipe.

[0031] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0032] An embodiment of the present application discloses a power busbar connector.

[0033] Reference Figure 1 A power busbar connector includes a first connecting tube 2 and a second connecting tube 3 with exactly the same structure. The cross-sections of the first connecting tube 2 and the second connecting tube 3 are both square. The end of the busbar 1 is inserted into the first connecting tube 2, and the first connecting tube 2 is rotatably connected to the second connecting tube 3. An elastic bellows 11 is bonded between the first connecting tube 2 and the second connecting tube 3. The elastic bellows 11 is used to seal the gap between the first connecting tube 2 and the second connecting tube 3.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 A baffle 12 is welded inside the first connecting tube 2, and the baffle 12 is used to abut the end of the busbar 1. The insulating shaft 8 is coaxially connected to the rotation center of the first connecting tube 2, and the second connecting tube 3 rotates with the insulating shaft 8. A conductive plate 4 is arranged on the first connecting tube 2, and a conductive support ring 9 is coaxially bonded to the insulating shaft 8. The end of the conductive plate 4 on the first connecting tube 2 and the end of the conductive plate 4 on the second connecting tube 3 are both rotatably connected to the conductive support ring 9, and the conductive support ring 9 supports the conductive plate 4.

[0035] The construction workers rotate the second connecting pipe 3 according to the angle of the corner in the building, thereby changing the angle between the first connecting pipe 2 and the second connecting pipe 3. During this process, the conductive plate 4 rotates around the axis of the conductive support ring 9, and then the end of the busbar 1 is inserted into the first connecting pipe 2 or the second connecting pipe 3 until the end of the busbar 1 abuts against the baffle 12.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 A fixing assembly 5 is arranged on the first connecting tube 2, and the fixing assembly 5 is used to fix the busbar 1 on the conductive plate 4. The fixing assembly 5 includes a spring plate 51 welded to the conductive plate 4, and a clamping plate 52 is welded on the spring plate 51. The conductive plate 4, the spring plate 51 and the clamping plate 52 can all be made of copper material. A clamping bolt 53 is bolted to the first connecting tube 2.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 An insulating plate 13 is bonded to the side of the clamping plate 52 facing the clamping bolt 53. The insulating plate 13 is rotatably engaged with the end of the clamping bolt 53. A plurality of anti-slip cones 7 are welded to the side of the clamping plate 52 facing away from the clamping bolt 53. The clamping bolt 53 is used to clamp the clamping plate 52 onto the busbar 1. An anti-loosening block 10 is threadedly connected to the clamping bolt 53, and the anti-loosening block 10 is used to tighten the first connecting pipe 2.

[0038] When the busbar 1 abuts the baffle 12, the construction worker tightens the clamping bolt 53, and the clamping bolt 53 pushes the insulating plate 13. The insulating plate 13 drives the clamping plate 52 to continuously approach the busbar 1. During this process, the tip of the anti-slip cone 7 continuously penetrates into the busbar 1, and then the construction worker rotates the anti-loosening block 10, and the anti-loosening block 10 abuts against the outer wall of the first connecting pipe 2.

[0039] Reference Figure 1 、 Figure 2 and Figure 3 An angle control assembly 6 is arranged between the first connecting tube 2 and the second connecting tube 3. The angle control assembly 6 is used to control the angle between the first connecting tube 2 and the second connecting tube 3. The angle control assembly 6 includes a mounting rod 14 welded to the first connecting tube 2, and an angle disk 61 is welded to the mounting rod 14. The axis of the angle disk 61 is coaxial with the rotation center of the first connecting tube 2.

The end of the angle rod 62 facing away from the angle disc 61 is welded to the second connecting pipe 3. A fixing screw 63 is bolted to the angle rod 62. A plurality of fixing holes 64 are evenly arranged on the angle disc 61 along the circumference of its axis. The fixing holes 64 are threadedly engaged with the fixing screws 63.

[0041] Then the construction worker screws the fixing screw 63 on the angle rod 62 , and the fixing screw 63 is screwed into the fixing hole 64 on the angle plate 61 , thereby fixing the angle between the first connecting pipe 2 and the second connecting pipe 3 .

[0042] The implementation principle of a power busbar connector in an embodiment of the present application is as follows: the construction personnel rotate the second connecting tube 3 according to the angle of the corner in the building, thereby changing the angle between the first connecting tube 2 and the second connecting tube 3. During this process, the conductive plate 4 rotates around the axis of the conductive support ring 9, and then the end of the busbar 1 is inserted into the first connecting tube 2 or the second connecting tube 3 until the end of the busbar 1 abuts against the baffle 12.

[0043] When the busbar 1 abuts the baffle 12, the construction worker tightens the clamping bolt 53, and the clamping bolt 53 pushes the insulating plate 13. The insulating plate 13 drives the clamping plate 52 to continuously approach the busbar 1. During this process, the tip of the anti-slip cone 7 continuously penetrates into the busbar 1, and then the construction worker rotates the anti-loosening block 10, and the anti-loosening block 10 abuts against the outer wall of the first connecting pipe 2.

[0044] Then the construction worker screws the fixing screw 63 on the angle rod 62 , and the fixing screw 63 is screwed into the fixing hole 64 on the angle plate 61 , thereby fixing the angle between the first connecting pipe 2 and the second connecting pipe 3 .
