[0025] The present invention proposes a connection structure 1000 for connecting an insulator 4 and a cable 5.

[0026] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the connection structure 1000 includes a first connector 1, a second connector 2 and a third connector 3; the first connector 1 is detachably connected to the insulator 4, the second connector 2 is detachably connected to the cable 5, and the third connector 3 includes a first connecting portion 31 and a second connecting portion 32 connected to each other, the first connector 1 is detachably connected to the first connecting portion 31, and the second connector 2 is detachably connected to the second connecting portion 32.

[0027] In the technical solution of the present invention, the first connector 1 is detachably connected to the insulator 4, the second connector 2 is detachably connected to the cable 5, and the first connector 1 and the second connector 2 are connected by the third connector 3. This can adapt to insulators 4 and cables 5 of different specifications and sizes. By simply selecting the appropriate combination of the first connector 1, the second connector 2 and the third connector 3 according to actual needs, a good connection effect can be achieved, which improves the versatility and applicability of the entire connection structure 1000.

[0028] Specifically, in one embodiment of the present invention, please refer to... Figure 1 and Figure 2 The first connecting member 1 includes a U-shaped connecting member 11, a connecting block 12, and two nuts. The U-shaped connecting member 11 and the connecting block 12 form a limiting cavity, which is used to limit the insulator 4. The two ends of the U-shaped connecting member 11 pass through the connecting block 12 and the first connecting part 31 in sequence, and are threadedly connected to a nut. The open end of the U-shaped connecting member 11 is adapted to the shape of the insulator 4, and can be engaged with the insulator 4 from the side, playing a preliminary fixing and limiting role. The connecting block 12 is designed to correspond to the closed end of the U-shaped connecting member 11. When the U-shaped connecting member 11 is engaged with the insulator 4, the connecting block 12 and the U-shaped connecting member 11 form a limiting cavity. The shape and size of the limiting cavity are precisely matched with the local shape of the insulator 4, thereby playing a more stable limiting role for the insulator 4 and preventing the insulator 4 from shaking or displacing during the connection process. The two ends of the U-shaped connector 11 pass through the connecting block 12 and the first connecting part 31, respectively, and are then aligned with and screwed into the threaded holes of the two nuts. By tightening the nuts, the U-shaped connector 11, the connecting block 12, and the first connecting part 31 are tightly connected, thereby firmly fixing the first connecting part 1 to the insulator 4, while ensuring a stable connection with the first connecting part 31 of the third connecting part 3. This structure can be adjusted according to insulators 4 of different sizes and shapes. For example, by replacing the connecting block 12 or the U-shaped connector 11 with different sizes, it can adapt to various types of insulators 4, making the connection structure 1000 have a wider range of applications.

[0029] Furthermore, in one embodiment of the present invention, please refer to... Figure 1 and Figure 2The connecting block 12 has a relief groove 121 formed on the side facing the limiting cavity. The relief groove 121 is arc-shaped, and its curvature matches the curvature of the corresponding part on the insulator 4, allowing it to closely fit the arc-shaped structure of the insulator 4 surface, such as the sheds or other arc-shaped components. During installation, the arc-shaped relief groove 121 not only effectively avoids protrusions on the insulator 4 but also forms surface contact with the insulator 4 surface through its arc-shaped surface, thus providing a more uniform support force and pressure distribution. This design allows the connecting block 12 to better disperse stress when in contact with the insulator 4, reducing excessive local pressure and thus lowering the risk of damage to the surface of the insulator 4. Simultaneously, the smooth inner surface of the arc-shaped relief groove 121 helps reduce friction with the insulator 4, making it easier to adjust the position of the connecting block 12 and ensuring a smooth installation process.

[0030] Specifically, in one embodiment of the present invention, the first connecting portion 31 has two first waist-shaped holes, and the two ends of the U-shaped connector 11 are respectively inserted through one of the first waist-shaped holes. The two first waist-shaped holes extend along the length direction of the first connecting portion 31. During installation, the two ends of the U-shaped connector 11 can be finely adjusted along the length direction of the first waist-shaped holes, thereby adjusting the relative position between the first connector 1 and the first connecting portion 31.

[0031] Furthermore, in one embodiment of the present invention, the connecting structure 1000 further includes two washers, which are respectively fitted onto both ends of the U-shaped connector 11 and located between the nut and the first connecting portion 31. During installation, after both ends of the U-shaped connector 11 pass through the connecting block 12 and the first connecting portion 31, the washers are fitted onto both ends of the U-shaped connector 11, located between the contact surfaces of the nut and the first connecting portion 31. The main function of the washers is to distribute the pressure generated when the nut is tightened, preventing damage to the contact surfaces of the first connecting portion 31 or the nut due to pressure concentration. At the same time, the washers can also reduce the friction between the nut and the first connecting portion 31, making the tightening of the nut smoother and ensuring the tightness and stability of the connection.

[0032] Specifically, in one embodiment of the present invention, please refer to... Figure 2 The second connector 2 includes two clamping blocks 21 connected by two bolts to clamp the cable 5. Both bolts pass through the second connecting portion 32. During installation, the two clamping blocks 21 are connected by two bolts, allowing them to tightly clamp the cable 5 and thus secure it. The two bolts pass through bolt holes on the clamping blocks 21 and further through the second connecting portion 32, and are then secured with nuts. The design of the second connecting portion 32 ensures that the bolts form a stable connection with the second connector 2 after passing through the clamping blocks 21, while the other end of the bolt engages with the nut to ensure the overall tightness of the structure.

[0033] Furthermore, in one embodiment of the present invention, please refer to... Figure 1 and Figure 2 Each clamping block 21 has a limiting groove 211 formed on one side facing the other clamping block 21. The shape and size of the limiting groove 211 are designed according to the shape of the cable 5 to provide additional limiting effect when clamping the cable 5. When the two clamping blocks 21 are connected by bolts and clamp the cable 5, the cable 5 is limited between the two limiting grooves 211. The limiting grooves 211 can effectively prevent the cable 5 from lateral displacement or torsion between the clamping blocks 21, thereby enhancing the stability of clamping. Through the limiting effect of the limiting grooves 211 on the cable 5, the contact between the clamping block 21 and the cable 5 can be made tighter and more uniform, improving the uniformity of the clamping force distribution, thereby enhancing the reliability of clamping.

[0034] Specifically, in one embodiment of the present invention, the limiting groove 211 is an arc-shaped groove. Its curvature matches the outer diameter of the cable 5, which can closely fit the outer surface of the cable 5. When the two clamping blocks 21 clamp the cable 5, the arc-shaped groove forms a surface contact with the surface of the cable 5, providing a uniform clamping force distribution.

[0035] Furthermore, in one embodiment of the present invention, the second connecting portion 32 forms two second oblong holes, with each bolt passing through one of the second oblong holes. The two second oblong holes extend along the length of the second connecting portion 32. During installation, the bolts can be finely adjusted along the length of the second oblong holes, thereby adjusting the clamping force between the clamping block 21 and the cable 5, as well as the relative position between the clamping block 21 and the second connecting portion 32. By adjusting the position of the bolts in the second oblong holes, the clamping force between the clamping block 21 and the cable 5 can be evenly distributed, reducing stress concentration caused by inaccurate positioning, thereby enhancing the stability and reliability of the connection. Moreover, in actual installation, the second oblong holes provide greater tolerance, allowing construction personnel to connect without precisely aligning each component, simplifying the installation steps and improving construction efficiency.

[0036] Specifically, in one embodiment of the present invention, the first connecting portion 31 and the second connecting portion 32 are arranged perpendicularly. The perpendicular arrangement of the first connecting portion 31 and the second connecting portion 32 forms an L-shaped connection structure 1000. This design ensures that the connection direction between the first connecting member 1 and the insulator 4 and the connection direction between the second connecting member 2 and the cable 5 are perpendicular to each other, thereby forming a stable right-angle connection structure 1000 in space. The perpendicular arrangement of the first connecting portion 31 and the second connecting portion 32 better adapts to the spatial layout of the insulator 4 and the cable 5 in the power transmission system, making the connection structure 1000 more compact and reasonable, and reducing space occupation.
