Description

Technical Field

[0001] This utility model specifically relates to a high-voltage resistant electrical insulator connection device. Background Technology

[0002] Electrical insulators, also known as dielectrics, are substances that do not conduct electric current under normal conditions. Their molecules have tightly bound positive and negative charges, very few freely moving charged particles, and extremely high resistivity. These materials are used as insulators or for insulating purposes in electrical equipment. They can be classified according to their applications as follows:

[0003] Supporting insulators: such as insulators and insulating posts, used to support conductors or equipment; isolating insulators: such as insulating sleeves and insulating boards, used to isolate conductive components; protective insulators: such as insulating tape and insulating coatings, used to protect the surface of wires or equipment; when installed and used, the above types of insulators can improve the transmission stability of communication equipment and play an irreplaceable role.

[0004] Currently, when installing isolation-type electrical insulators, the busbar needs to be inserted and exited from inside the insulator. However, these electrical insulators are usually hollow cylinders. Once the busbar is inserted and fixed, its angle cannot be adjusted. This results in the electrical insulator not being able to make adaptive adjustments when connected to external equipment, leading to a slow installation process and low efficiency.

[0005] Therefore, it is necessary to invent a high-voltage resistant electrical insulator connection device to solve the above problems. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a high-voltage resistant electrical insulator connection device. By providing an outer sleeve and an inner liner, the busbar installed inside the inner liner can freely adjust its angle as the inner liner rotates. Furthermore, the positioning component can achieve friction locking of the inner liner. This allows the busbar to make adaptive adjustments according to environmental requirements when the electrical insulator is connected to external equipment, facilitating installation by workers and greatly improving the installation efficiency of the electrical insulator.

[0022] This invention, by incorporating an outer sleeve and an inner liner, allows the busbar installed inside the inner liner to freely adjust its angle as the inner liner rotates. Furthermore, when the busbar's angle adapts to the installation environment, a positioning component enables friction locking of the inner liner, preventing it from rotating freely within the outer sleeve. This ensures the stability of the busbar after angle adjustment, allowing the electrical insulator to adapt to environmental requirements when connected to external equipment. This facilitates installation by personnel and significantly improves the installation efficiency of the electrical insulator. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figure 1-5 The high-voltage resistant electrical insulator connection device shown includes an outer sleeve 1, and an inner liner 2 is sleeved inside the outer sleeve 1.

[0035] Several mounting brackets 3 are connected to the inner wall of the inner lining tube 2, and the busbar passes through the mounting brackets 3 and is laid inside the inner lining tube 2;

[0036] The first ring plate 4 is installed at one end of the inner liner tube 2 and is used to drive the inner liner tube 2 to rotate along its axis inside the outer sleeve tube 1.

[0037] The outer conical surface 5 is located at the end of the inner liner tube 2 that is away from the first annular plate 4;

[0038] The positioning component 6 is adapted to the outer conical surface 5 and is used to position the inner liner tube 2 after rotation. The positioning component 6 includes a second ring plate 61. An annular insert plate 62 is connected to the side of the second ring plate 61 near the outer conical surface 5. An inner conical surface 63 is formed on the inner wall of the side of the annular insert plate 62 adjacent to the outer conical surface 5.

[0039] In one embodiment, an mounting plate 7 is connected to the outer side of the outer sleeve 1, and a reinforcing ring 8 is also sleeved on the outer side of the outer sleeve 1. The end of the reinforcing ring 8 is connected to the side wall of the mounting plate 7. The mounting plate 7 can install the electrical insulator on the external wall, and the reinforcing ring 8 increases the contact area between the outer sleeve 1 and the external mounting point, thereby increasing the overall installation strength of the electrical insulator.

[0040] In one embodiment, the mounting frame 3 includes a frame plate 31 sleeved on the outside of the busbar. At least one outer side of the frame plate 31 is equipped with a connecting rod 32. The other end of the connecting rod 32 is connected to the inner wall of the inner liner tube 2, so that when the inner liner tube 2 rotates, it can drive the busbar inside to rotate, thereby adaptively adjusting the installation angle of the busbar and facilitating the overall installation of the electrical insulator. At the same time, the entire mounting frame 3 is made of modified epoxy resin layer, thereby ensuring that the mounting frame 3, which is in direct contact with the busbar, has high strength and also has beneficial insulation properties, which can support and drive the busbar to rotate with the inner liner tube 2 without affecting the normal use of the busbar.

[0041] In one embodiment, at least one limiting ring 9 is connected to the outer side of the inner liner tube 2, and the inner wall of the outer tube 1 located at the limiting ring 9 is provided with a limiting groove 10 for accommodating the limiting ring 9. The limiting ring 9 can rotate inside the limiting groove 10 along its axial direction, but cannot be laterally offset to the left or right, so that the position of the inner liner tube 2 inside the outer tube 1 will not be laterally offset, thus ensuring the stable use of the electrical insulator.

[0042] In one embodiment, a nylon layer 11 is provided on the outer side of the outer conical surface 5, which greatly increases the friction between the inner conical surface 63 and the outer conical surface 5, improves the positioning ability of the inner liner tube 2, and can effectively prevent the inner liner tube 2 from rotating again after positioning.

[0043] In one embodiment, the insert plate and the outer sleeve 1 are threaded together, the inner conical surface 63 is adapted to the outer conical surface 5, and the outer sides of the first ring plate 4 and the second ring plate 61 are both equipped with dial buttons 12 to facilitate the installation of the electrical insulator by the staff.

[0044] The specific implementation method is as follows: In use of this utility model, for better understanding of this solution, reference numeral 13 is used to refer to the busbar;

[0045] Specifically, the staff inserts the outer sleeve 1 into the wall to be installed, and then pours concrete to complete the initial positioning of the outer sleeve 1. When using the busbar to connect the external equipment, if the angle of the busbar needs to be adjusted, the staff can directly turn the knob 12 on the outside of the second ring plate 61 to unscrew the annular insert plate 62. At this time, the inner cone surface 63 will move away from the outer cone surface 5 as the annular insert plate 62 leaves, and the inner liner tube 2 will no longer be squeezed. The limit is released. The staff can turn the knob 12 on the outside of the first ring plate 4 to make the first ring plate 4 drive the inner liner plate to rotate inside the outer sleeve 1, and further make the mounting bracket 3 inside the inner liner plate rotate, thereby driving the busbar to rotate along the axis of the inner liner tube 2. At this time, the tilt angle of the busbar, that is, the installation angle, can be changed to adapt to the installation environment in different scenarios, making it convenient for the staff to install the electrical insulator and greatly reducing the installation difficulty.

[0046] After the busbar angle is adjusted, the operator reverses the turn button 12 on the outer side of the second ring plate 61, causing the annular insert plate 62 to screw into the outer sleeve 1. As the annular insert plate 62 is continuously screwed in, the inner conical surface 63 will press against the outer side of the outer conical surface 5 again, thereby applying pressure to the entire inner liner 2. This converts the axial force into radial force through the conical effect of the inner conical surface 63 and the outer conical surface 5, achieving frictional locking of the inner liner 2. This prevents the inner liner 2 from rotating freely inside the outer sleeve 1, thus ensuring the stability of the busbar after the angle is adjusted.

[0047] Meanwhile, both the outer sheath 1 and the inner liner 2 are made of polytetrafluoroethylene, which gives the electrical insulator extremely excellent insulation properties and the ability to withstand very high voltages without being broken down, thus effectively ensuring the safe operation of the equipment in a high-voltage environment.

[0048] This implementation method specifically solves the problem in the prior art that when installing isolation-type electrical insulators, the busbar needs to be inserted and exited from inside the insulator. However, these electrical insulators are usually hollow cylinders. Once the busbar is inserted and fixed, the angle cannot be adjusted, resulting in the inability to make adaptive adjustments when connecting to external equipment, leading to a slow installation process and low efficiency.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
