Description

Technical Field

[0001] This utility model relates to the field of insulator cap technology, specifically an insulator cap. Background Technology

[0002] Insulator caps are metal components installed on top of insulators or at specific locations. They are typically made of malleable cast iron or other metal materials. Their main function is to protect insulators from external environmental influences and mechanical damage, thereby ensuring the normal function of the insulators and extending their service life. The manufacturing process of insulator caps includes steps such as preparing the cap casting, grinding and shot blasting, washing and drying, immersion in flux, drying, galvanizing, cooling, inspecting the zinc layer thickness, passivation, and surface grinding and finishing. These steps ensure good adhesion between the cap casting and the plating, while reducing wastewater discharge and costs, meeting environmental protection requirements. Insulator caps play a crucial role in power systems. To ensure the safe and stable operation of power systems, the selection, installation, and maintenance of insulator caps must be taken seriously.

[0003] In existing technologies, under shear loads, even slight slippage between the insulator and the cap can cause the threaded connection to loosen. Ideally, shear loads should not cause the bolt or nut to rotate in the direction of loosening. However, in actual use, due to various factors such as material wear and thread fit precision, loosening between the insulator cap and the insulator can lead to a decrease in insulation performance and even cause electrical faults such as short circuits or breakdowns, threatening the safe operation of the power system. Therefore, we need an insulator cap. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model embodiment provides an insulator cap, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes an insulator body 1, a connecting assembly 2 on top of the insulator body 1, a cap body 3 on top of the connecting assembly 2, and an installation assembly 4 inside the cap body 3. The connecting assembly 2 includes an installation sleeve 201, a positioning groove 202 on top of the installation sleeve 201, a threaded groove 203 inside the installation sleeve 201, a first rubber pad 204 fixedly connected to the top of the installation sleeve 201, and a stud 205 threadedly connected to the threaded groove 203. The installation sleeve 201 and the stud 205 form a threaded structure through the threaded groove 203, and the outer diameter of the stud 205 matches the inner diameter of the threaded groove 203. Furthermore, the outer wall of the stud 205 fits snugly against the inner wall of the threaded groove 203, enhancing the connection between the mounting sleeve 201 and the stud 205. This allows the stud 205 to be securely installed within the threaded groove 203. A second rubber pad 206 is fixedly connected to the bottom of the cap body 3. The mounting sleeve 201 forms a fastening structure with the cap body 3 via the first rubber pad 204. The shape and size of the first rubber pad 204 match the shape and size of the second rubber pad 206, and one side of the first rubber pad 204 fits snugly against one side of the second rubber pad 206, further enhancing the connection between the mounting sleeve 201 and the first rubber pad 204. The cap body 3 can be connected to the first rubber pad 204 by relying on the second rubber pad 206 at the bottom, which can be attached to one side of the cap body 1. This improves the connection stability between the insulator body 1 and the cap body 3. The cap body 3 has a fixing bolt 207 inside. The cap body 3 and the mounting sleeve 201 are fixed together by the fixing bolt 207. One end of the fixing bolt 207 passes through the cap body 3 and is fastened inside the mounting sleeve 201. This simplifies the installation of the fixing bolt 207, allowing it to secure the cap body 3 to the mounting sleeve 201 and improving the connection between them. To improve connection stability, when connecting the insulator body 1 and the cap body 3, the stud 205 at the lower end of the cap body 3 can be directly inserted into the insulator body 1. By rotating the cap body 3, the stud 205 can be tightened and installed in the screw groove 203, allowing the second rubber pad 206 on the cap body 3 to be tightly fitted to the surface of the first rubber pad 204. By rotating the fixing bolt 207, the fixing bolt 207 can be used to install the insulator body 1 and the cap body 3, further improving the connection stability between the insulator body 1 and the cap body 3 and meeting people's daily use needs.

[0022] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the mounting assembly 4 includes a rod groove 401, with a long rod 402 movably connected inside the rod groove 401. The cap body 3 forms a movable structure with the long rod 402 through the rod groove 401. The inner diameter of the rod groove 401 matches the outer diameter of the long rod 402, and the inner wall of the rod groove 401 fits snugly against the outer wall of the long rod 402, enhancing the connection between the cap body 3 and the long rod 402. This allows the long rod 402 to be connected by being secured in the rod groove 401 at its bottom. A connecting rod 403 is provided on one side of the cap body 3. The outer wall of the connecting rod 403 has an external thread 404, and a nut 405 is threaded onto the outer wall of the external thread 404. The connecting rod 403 and the nut 405 form a fastening structure through the external thread 404, and the inner diameter of the nut 405 matches the outer diameter of the connecting rod 403. The dimensions are matched, and the inner wall of the nut 405 fits snugly against the outer wall of the connecting rod 403, enhancing the connection between the connecting rod 403 and the nut 405. This allows the nut 405 to be fastened to the outer wall of the connecting rod 403 for installation, further strengthening the long rod 402. When connecting the iron cap body 3 to the long rod 402 on the external bracket, the long rod 402 can be fastened from the side into the rod groove 401 inside the iron cap body 3, allowing the long rod 402 to move within the iron cap body 3 and reducing the risk of damage in severe weather. Furthermore, since the connecting rod 403 passes through one side of the iron cap body 3 and the nut 405 is fastened to the external thread 404 of the connecting rod 403, the possibility of the long rod 402 moving out from the side can be reduced, improving the practicality of the iron cap.

[0023] Working principle: When connecting the insulator body 1 and the cap body 3, the stud 205 at the lower end of the cap body 3 can be directly inserted into the insulator body 1. By rotating the cap body 3, the stud 205 can be tightened and installed in the screw groove 203, allowing the second rubber pad 206 on the cap body 3 to be tightly fitted to the surface of the first rubber pad 204. By rotating the fixing bolt 207, the insulator body 1 and the cap body 3 can be installed, further improving the connection between the insulator body 1 and the cap body 3. The connection stability meets people's daily use needs. In addition, when the iron cap body 3 is connected to the long rod 402 on the external bracket, the long rod 402 can be fastened from the side to the rod groove 401 inside the iron cap body 3, and the long rod 402 can move inside the iron cap body 3, reducing the possibility of damage caused by bad weather. Furthermore, the connecting rod 403 passes through one side of the iron cap body 3 and is fastened to the external thread 404 of the connecting rod 403 by the nut 405, thereby reducing the possibility of the long rod 402 moving from the side and improving the practicality of the iron cap.
