[0040] References to "embodiments" or "implementations" herein mean that a particular feature, structure, or characteristic described in conjunction with the embodiments or implementations may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] Insulators are a common power component in power systems and are often used in transmission lines to support and fix conductors. When erecting transmission lines, aluminum wire is usually used to tie the conductors to insulating porcelain bottles. Currently, most insulators are made of fired ceramics. When insulators are subjected to external forces or are punctured, they will break into multiple fragments and fall off, and the conductors will also fall off, posing a safety hazard. In addition, the fixing method of insulators in the current related technology is not stable in some scenarios, and the fixed part may also fall off after the conductor swings for a long time.

[0042] In view of this, the present embodiment provides an insulator 10. The insulator 10 can be prevented from being separated from the conductor after being broken down.

[0043] See also Figure 1 and Figure 2 , an insulator 10, comprising: a plurality of first covering members 11, a plurality of second covering members 12, and a connecting assembly 20;

[0044] The insulator 10 is provided with a cavity 18 inside, and the inner side wall of the insulator 10 is divided into a first part 13 and a second part 14 along the radial direction of the insulator 10; the first covering member 11 and the second covering member 12 are both arranged in the cavity 18, a plurality of the first covering members 11 are arranged in sequence in the first part 13, and a plurality of the second covering members 12 are arranged in sequence in the second part 14; the first covering member 11 extends to the second part 14, and the second covering member 12 extends to the first part 13, and the first covering member 11 overlaps with the second covering member 12;

[0045] The insulator has a first end 15 and a second end 16 , and the first end 15 and the second end 16 are both provided with a connection assembly 20 .

[0046] The interior of the insulator 10 in the present invention is set as a cavity 18, and the side wall of the insulator 10 is divided into a first part 13 and a second part 14, the first covering member 11 is set in the first part 13, and the first covering member 11 is extended to the second part 14, and the second covering member 12 is set in the second part 14, and the second covering member 12 is extended to the first part 13, so that the first covering member 11 and the second covering member 12 can intersect, so that they can fit tightly and generate friction between the first covering member 11 and the second covering member 12, so that the stability of the body structure of the insulator 10 can be improved, and because the first covering member 11 and the second covering member 12 are both connected to the side wall of the insulator 10, after the insulator 10 is broken, the first covering member 11 and the second covering member 12 can limit the broken insulator 10, prevent the insulator 10 from scattering and failing, and thus reduce the risk of causing the wire to fall.

[0047] It can be understood that the first covering member 11 and the second covering member 12 are arranged in a plate or strip shape, and the first covering member 11 and the second covering member 12 are arranged in an alternating manner, so that the first covering member 11 and the second covering member 12 can have a larger contact area, so that the insulator 10 will not fail immediately after being broken. The connecting assembly 20 arranged on the insulator 10 can be used to connect the wire. By connecting the connecting assembly 20 to the wire, after a part of the insulator 10 fails, the other part can continue to be used normally, so as to achieve the purpose of improving the stability of the insulator 10.

[0048] In some embodiments, the first covering member 11 has a first surface 111 in contact with the second covering member 12; the second covering member 12 has a second surface 121 in contact with the first covering member 11, and both the first surface 111 and the second surface 121 are configured to be provided with textures.

[0049] It can be understood that the first covering member 11 has a first surface 111, and the second covering member 12 has a second surface 121. Textures are provided on the first surface 111 and the second surface 121. When the first surface 111 and the second surface 121 are in contact, the textures of the first surface 111 and the textures of the second surface 121 are in contact, so that the first surface 111 and the second surface 121 have a larger contact area, so that the friction between the first covering member 11 and the second covering member 12 can be improved. When the first part 13 or the second part 14 of the insulator 10 is broken, the first covering member 11 and the second covering member 12 can limit the broken insulator of the first part and the second part, so that the insulator will not fail immediately, thereby achieving the purpose of improving the stability of the insulator, and at the same time achieving the purpose of improving the mechanical strength and durability of the insulator 10.

[0050] Optionally, the texture design of the first surface 111 and the second surface 121 can be set to a relatively rough surface, or the first surface 111 and the second surface 121 can be set to a relatively rough surface. Figure 3 or Figure 4 In the arrangement of the lines shown, when the lines of the two parts are opposite in the relative direction, the interaction force increases, so that it is difficult for the first covering member 11 to be separated from the second covering member 12, or the second covering member 12 to be separated from the first covering member 11; at the same time, it helps to offset the torsional stress of the insulator 10. Since the lines have opposite paths, when the torsional force is applied to the first covering member 11 or the second covering member 12, the lines will resist the torsional force, so that it is more difficult for the first covering member 11 or the second covering member 12 to rotate or loosen, which can effectively prevent the insulator 10 from failing or loosening. This ensures the reliability of the insulator 10 in long-term operation.

[0051] It should be particularly noted that since there are multiple first covering members 11 and second covering members 12, the first covering member 11 has two first surfaces 111, which are disposed opposite to each other and have the same texture; similarly, the second covering member 12 has two second surfaces 121, which are disposed opposite to each other and have the same texture.

[0052] Optionally, the textures of the first surface 111 and the second surface 121 include but are not limited to the textures shown in the figure, which may be convex or irregular in shape, etc.

[0053] In some embodiments, the insulator 10 has an axis, and the length of the first covering member 11 and the length of the second covering member 12 are both greater than half of the outer circumference of the insulator.

[0054] It can be understood that the length of the first covering member 11 and the second covering member 12 of the insulator 10 exceeds half of the circumferential length of the insulator, which can increase the surface contact area of ​​the first covering member 11 and the second covering member 12, improve the friction between the first surface 111 and the second surface 121, and improve the distribution of internal stress of the insulator 10, reduce the damage of the insulator 10 caused by excessive stress concentration at certain points, adapt to higher loads, improve the stability of the entire structure and extend the service life of the insulator 10.

[0055] See also Figure 2 , in some embodiments, the connection assembly 20 includes a first connection member 21 and a second connection member 22;

[0056] The insulator 10 has a first end 15 and a second end 16 that are oppositely disposed. The first connecting member 21 is disposed at the first end 15 , and the second connecting member 22 is disposed at the second end 16 .

[0057] It can be understood that the first connector 21 and the second connector 22 are respectively located at the two ends of the insulator 10, which can make the installation and replacement of the insulator 10 more flexible, and when in use, the first connector 21 and the second connector 22 can be connected to the wire at the same time, or the first connector 21 is connected to the wire, and the second connector 22 is fixedly arranged, which can enhance the flexibility of the insulator 10 in different application scenarios, so that it can adapt to different installation conditions or connection requirements. And the first connector 21 and the second connector 22 are respectively arranged at the two ends of the insulator 10, so that the insulator 10 can also form a more stable connection structure at the connection port. When the insulator 10 is subjected to tensile, compressive and bending forces, the stress distribution is uniform, reducing the risk of failure of the insulator 10.

[0058] See also Figure 2In some embodiments, the first connecting member 21 includes: a first connecting sub-portion 211 and a second connecting sub-portion 212; the first connecting sub-portion 211 and the second connecting sub-portion 212 are arranged at intervals on both sides of the first end 15;

[0059] The second connecting member 22 includes: a third connecting sub-portion 221 and a fourth connecting sub-portion 222; the third connecting sub-portion 221 and the fourth connecting sub-portion 222 are arranged at intervals on both sides of the second end 16;

[0060] The first connecting sub-portion 211 , the second connecting sub-portion 212 , the third connecting sub-portion 221 , and the fourth connecting sub-portion 222 are all provided with connecting holes.

[0061] It can be understood that the first connecting member 21 includes: a first connecting sub-portion 211 and a second connecting sub-portion 212, wherein the first connecting sub-portion 211 and the second sub-portion are both fixedly connected to the insulator 10 to ensure the stability of the first connecting sub-portion 211 and the second connecting sub-portion 212 after being connected to the wire; specifically, the first connecting sub-portion 211 and the second connecting sub-portion 212 are arranged at intervals so that after the insulator 10 is broken, one of the connecting sub-portions can play a connecting role with multiple wires, thereby preventing the wires from falling. At the same time, due to the interaction between the first matching portion and the second matching portion, the first connecting sub-portion 211 and the second connecting sub-portion 212 can also play a role of mutual restraint and mutual restriction, thereby achieving the purpose of improving the stability of the insulator 10.

[0062] It is understandable that the first connecting sub-portion 211 and the second connecting sub-portion 212 are provided on the insulator 10 to better resist the torsion and bending of the insulator 10 caused by external forces, and the connection points on both sides thereof can effectively absorb and disperse the vibration energy, reduce the impact of the vibration on the structure of the insulator 10, and improve the anti-deformation ability of the overall structure. At the same time, it can also improve the convenience of installation and achieve the purpose of improving construction efficiency.

[0063] See also Figure 5 , in some embodiments, further comprising: a mounting plate 30, an insulating pin 40 and a fixing assembly 50;

[0064] One end of the insulating needle 40 passes through the mounting plate 30, and the other end of the insulating needle 40 is connected to the insulator 10. The fixing assembly 50 is used to fix the insulating needle 40 and the mounting plate 30; the outer wall of the insulator 10 is provided with a plurality of insulating sheds 17, and a protrusion is provided between adjacent insulating sheds 17.

[0065] It can be understood that in order to better fix the insulator 10, one end of the insulating needle 40 is connected to the insulator 10, and the other end of the insulating needle 40 penetrates the mounting plate 30, that is, it is arranged on the mounting plate 30. In order to fix the insulating needle 40 and the insulator 10, a fixing assembly 50 is arranged on the insulating plate. This structure can greatly enhance the installation firmness of the insulator 10, ensure that the structure is stable during long-term use, and is not easy to loosen or shift, and can also prevent the insulator 10 from shaking or shifting, thereby ensuring the stable operation of the electrical system.

[0066] It can be understood that the fixing assembly 50 is detachably arranged on the mounting plate 30, which can also facilitate the later replacement and maintenance of the insulator 10. A plurality of equidistant insulating sheds 17 are fixedly connected to the outer wall of the insulator 10, and the shed structure effectively extends the creepage distance to achieve the purpose of improving the stability of the insulator 10 when in use.

[0067] Optionally, the insulator 10 may be made of a composite material.

[0068] See also Figures 5 to 7 In some embodiments, the fixing assembly 50 includes: a baffle 51, a screw rod 52, and a plurality of bolts 53.

The multiple bolts 53 pass through the fixing block, the mounting plate 30 and the baffle 51 in sequence, and a second nut 56 is sleeved on one end of the bolt 53, and the above-mentioned mounting plate 30 can be fixed by the second nut 56. In order to achieve a better fixing effect, a first movable groove 531 is provided at one end of the bolt 53 away from the fixing portion 551, and the bolt 53 is fixed by arranging a limiting structure 60 in the first movable groove 531, thereby reducing the risk of loosening of the bolt 53, ensuring that the system can still maintain efficient operation during long-term operation, and improving the overall stability of the insulator 10.

[0073] See also Figures 5 to 7 In some embodiments, a plurality of first through holes 71 are provided along the thickness direction of the baffle plate 51, a plurality of second through holes 72 are provided along the thickness direction of the mounting plate 30, and a plurality of third through holes 73 are provided on the fixing portion 551;

In addition, the first through hole 71, the second through hole 72 and the third through hole 73 can be provided in plurality, and similarly, the bolt 53 can also be provided in plurality. The parallel use of multiple bolts 53 can evenly distribute mechanical stress, avoid excessive stress on a single bolt 53, reduce deformation or loosening caused by uneven load, and provide sufficient tightening force to avoid loosening or sliding, thereby enhancing the safety of the overall structure.

The retaining ring 62 is sleeved on the outer side wall of the limiting shaft 61, so that the retaining ring 62 can limit the displacement when the sleeve is replaced, so that its limiting effect is further enhanced, and the possibility of the insulator 10 falling during use is reduced.

[0080] See also Figures 5 to 7 In some embodiments, the number of the limiting structures 60 is equal to the number of the bolts 53, so that the limiting structures 60 can better limit the bolts 53, thereby preventing the bolts 53 from falling and causing the insulator 10 to fail.
