[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1:

[0038] Referring to Figure 1 、 Figure 2 , Figure 3 and Figure 5 , an insulating tubular busbar device convenient for splicing, comprising:

[0039] The conductive column 2 is fixedly connected with an insulating sleeve 1 on the outer wall thereof. The insulating sleeve 1 is used to insulate the outer wall of the conductive column 2 to ensure the electrical safety of the equipment and avoid the occurrence of electric leakage.

[0040] A plurality of cards 4, one end of the card 4 is fixedly connected to the inside of the conductive column 2 in an annular array, and the other end of the card 4 extends towards the center of the conductive column 2 and contracts into a conical shape, making the structure more compact and stable.

[0041] A plurality of contact pieces 3, one end of the contact piece 3 is rotatably connected to the inside of the conductive column 2 in an annular array. A connecting block 15, a connecting block 2 and a telescopic rod 1 are arranged between the other end of the contact piece 3 and the conductive column 2. These components cooperate to enable the contact piece 3 to rotate and adjust flexibly. The top of the connecting block 15 is rotatably connected to the inner wall of the conductive column 2, and the bottom of the connecting block 2 is rotatably connected to the outer wall of the contact piece 3. Through this design, the reliable connection and stable support of the contact piece 3 are realized.

[0042] The first spring 18 is sleeved on the outer wall of the first telescopic rod 17. One end of the first spring 18 and the first telescopic rod 17 are both fixedly connected to the bottom of the first connecting block 15, and the other end of the first spring 18 and the first telescopic rod 17 are both fixedly connected to the bottom of the second connecting block 16. Through the elastic force of the spring, the contact piece 3 is always kept in a proper position. An insulating sleeve three 8 is arranged inside the conductive column 2. An insulating sleeve two 7 is fixedly connected to the outer wall of the insulating sleeve three 8. The insulating sleeve three 8 is fitted with the outer wall of the card 4 to ensure the insulation performance of the overall structure. A copper core 9 is fixedly connected inside the insulating sleeve three 8. The outer wall of the copper core 9 is attached to the inner wall of the contact piece 3. Through this close fit, a good electrical contact effect is ensured. A release sleeve 5 is slidably connected inside the conductive column 2. Limit rings 6 are fixedly connected to both ends of the release sleeve 5. The outer wall of the limit ring 6 is slidably connected inside the conductive column 2. Through the limit ring 6, the stable sliding of the release sleeve 5 inside the conductive column 2 is ensured;

[0043] Specifically, first, when connecting the insulated tubular busbar, insert the insulating sleeve two 7 into the conductive column 2 so that the copper core 9 inside the insulating sleeve two 7 contacts the contact piece 3. One side of the contact piece 3 rotates inside the conductive column 2. The end of the contact piece 3 towards the inside of the conductive column 2 is supported by the tension of the first spring 18. The first spring 18 pushes the contact piece 3 to clamp and fit the outer wall of the copper core 9. The copper core 9 is locked inside the conductive column 2 by being fitted with the card 4 through the insulating sleeve three 8 on its outer wall inside the conductive column 2, ensuring that the copper core 9 will not come off when smoothly inserted into the conductive column 2. The insulating sleeve one 1 is used to further protect the conductive column 2 and ensure its insulation performance. In the installation of the insulated tubular busbar, this design ensures a firm connection between the copper core 9 and the conductive column 2, improving the convenience and safety of installation;

[0044] When disassembling it, just drive the limit ring 6 to retract the release sleeve 5 into the insulating sleeve one 1. The release sleeve 5 is limited inside the conductive column 2 through the limit ring 6, so that the release sleeve 5 drives the limit ring 6 to separate the card 4 on the inner wall of the conductive column 2 from the insulating sleeve three 8, and then the insulated tubular busbar can be separated from the conductive column 2.

[0045] Embodiment Two:

[0046] Refer to Figure 4 and Figure 6, an insulating tubular busbar device that is convenient for splicing: A base 10 is provided at the bottom of the first insulating sleeve 1. Inside the base 10, symmetrically arranged adjusting bolts 12 are rotatably connected. A fixing column 11 is threadedly connected to the outer wall of the adjusting bolt 12. The top of the fixing column 11 is fixedly connected to a first semi-ring 13. One end of the first semi-ring 13 is rotatably connected to a second semi-ring 14. Through this design, the adjusting bolt 12 can flexibly adjust the position of the fixing column 11, thereby adjusting the relative positions of the first semi-ring 13 and the second semi-ring 14 to adapt to conductors of different sizes. The other end of the first semi-ring 13 is fixedly connected to a limiting block 21. The outer wall of the limiting block 21 slides inside the second semi-ring 14. Symmetrically arranged second limiting plates 22 are slidably connected inside the limiting block 21. One side of the second limiting plate 22 is fixedly connected to a clamping block 23. The outer wall of the clamping block 23 is fitted inside the second semi-ring 14. This design enables the limiting block 21 to be stably fixed inside the second semi-ring 14. At the same time, the clamping block 23 can effectively prevent the sliding of the second limiting plate 22, ensuring the stability and reliability of the fixation. A second telescopic rod 24 is arranged inside the limiting block 21. A second spring 25 is sleeved on the outer wall of the second telescopic rod 24. Both ends of the second telescopic rod 24 and the second spring 25 are fixedly connected between the second limiting plates 22. Through the elastic force of the second spring 25, the second limiting plate 22 is always maintained in an appropriate position, ensuring stability in different environments. A first limiting plate 19 is slidably connected inside the second semi-ring 14. A release column 20 is fixedly connected inside the first limiting plate 19. Through the design of the first limiting plate 19, the release column 20 can flexibly adjust the position of the first limiting plate 19, thereby facilitating quick disassembly, assembly, and maintenance;

[0047] Specifically, when installing the insulating tubular busbar, first install the two sides of the base 10 at the required position through fixing bolts, place the insulating tubular busbar steadily on the first semi-ring 13, and then rotate the adjusting bolt 12 to adjust the position of the first semi-ring 13 to ensure that the busbar is firmly fixed. Next, flip the second semi-ring 14 so that the limiting block 21 at one end of the first semi-ring 13 is embedded inside one end of the second semi-ring 14, and ensure that the clamping block 23 inside the limiting block 21 is firmly fitted inside the second semi-ring 14. The clamping block 23 is supported by the tension of the second spring 25, making it not easy to separate inside the second semi-ring 14, thereby ensuring the stability and reliability of the busbar during installation;

[0048] When it is necessary to disassemble the first semi-ring 13 and the second semi-ring 14, just press the release columns 20 on both sides of the second semi-ring 14 to make the release columns 20 retract into the second semi-ring 14. The release columns 20 will drive the clamping blocks 23 to retract into the limiting block 21, thereby separating the clamping blocks 23 from the second semi-ring 14. At this time, one end of the first semi-ring 13 and the second semi-ring 14 can be separated. After separation, the clamping blocks 23 extend out of the limiting block 21 again under the tension of the second spring 25 to achieve reset.

[0049] Working principle: When using this easily spliced insulated tubular busbar device, first, when connecting the insulated tubular busbar, insert the second insulating sleeve 7 into the conductive column 2. Subsequently, make the copper core 9 inside the second insulating sleeve 7 contact the contact piece 3. The outer side of the contact piece 3 rotates inside the conductive column 2. One end of the contact piece 3 facing the inside of the conductive column 2 is supported by the tension of the first spring 18. The first spring 18 pushes the contact piece 3 to clamp and fit against the outer wall of the copper core 9. The copper core 9 is locked inside the conductive column 2 by fitting with the card 4 through the third insulating sleeve 8 on its outer wall when inserted into the conductive column 2 smoothly without detachment. The first insulating sleeve 1 is used to further protect the conductive column 2 for insulation. When installing the insulated tubular busbar, first install the two sides of the base 10 at the required installation position through fixing bolts, place the insulated tubular busbar on the first semi-ring 13, and then rotate the adjusting bolt 12 to adjust the position of the first semi-ring 13. Flip the second semi-ring 14 so that the limiting block 21 at one end of the first semi-ring 13 is inserted into the inside of one end of the second semi-ring 14, and make the clamping block 23 in the limiting block 21 fit inside the second semi-ring 14 for connection. The clamping block 23 is supported by the tension of the second spring 25 so that the clamping block 23 is inserted into the second semi-ring 14 and is not easily separated;

[0050] When disassembling it, just drive the release sleeve 5 and the limiting ring 6 to retract into the first insulating sleeve 1. The release sleeve 5 is limited inside the conductive column 2 through the limiting ring 6, so that the release sleeve 5 drives the limiting ring 6 to separate the card 4 on the inner wall of the conductive column 2 from the third insulating sleeve 8, and then the insulated tubular busbar can be separated from the conductive column 2;

[0051] When it is necessary to disassemble the first semi-ring 13 and the second semi-ring 14, just press the release columns 20 on both sides of the second semi-ring 14 to make the release columns 20 retract into the second semi-ring 14, so that the release columns 20 drive the clamping blocks 23 to retract into the limiting block 21, and then separate the clamping blocks 23 from the second semi-ring 14 to separate one end of the first semi-ring 13 and the second semi-ring 14. After separation, the clamping blocks 23 extend out of the limiting block 21 again and reset through the tension of the second spring 25.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
