[0002] Insulators are devices installed between conductors at different potentials, or between a conductor and a grounded structure, and are designed to withstand voltage and mechanical stress. Existing insulators lack a positioning function, causing them to rotate during use, impacting their proper function. Furthermore, the creepage distance between existing insulators and mounting screws is too small, compromising their reliability. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide an insulator with a positioning function, thereby increasing the positioning function, preventing the insulator from rotating during use, and improving the reliability of the insulator.

[0004] To solve the above technical problems, an insulator with a positioning function is provided in accordance with the utility model, which includes a disc-shaped body, a through hole is provided in the center of the disc-shaped body, a first insulating ring and a second insulating ring are provided on the top and bottom of the disc-shaped body respectively, an annular positioning groove is formed between the outer wall of the second insulating ring and the bottom of the disc-shaped body, a third insulating ring is provided at the bottom center of the disc-shaped body, an annular groove located outside the third insulating ring is provided at the bottom of the disc-shaped body, a nut positioning groove connected to the through hole is provided at the top center of the disc-shaped body, and a longitudinal positioning groove is provided on the side wall of the disc-shaped body.

[0005] Preferably, two longitudinal positioning grooves are symmetrically provided on the side wall of the disc-shaped body.

[0006] Preferably, the nut positioning groove is arranged in a regular hexagonal shape.

[0007] The beneficial effects of the utility model are as follows: the utility model provides an insulator with a positioning function. In order to cooperate with the use of the insulator, a positioning column that matches the longitudinal positioning groove should be provided on the fixing plate for installing the insulator, and a hole position corresponding to the through hole and a limiting ring that matches the annular positioning groove should be opened on the fixing plate. When installing the insulator, the insulator is placed on the fixing plate and the positioning column is engaged with the longitudinal positioning groove. The limiting ring will be fitted on the annular positioning groove, and a nut that matches its shape is placed on the nut positioning groove. Then, the hole position, the through hole and the nut are connected with the mounting screw to prevent the insulator from rotating on the fixing plate. The insulator can be effectively positioned. By arranging the first insulating ring, the second insulating ring, the annular groove and the third insulating ring, the creepage insulation distance between the fixing plate and the mounting screw can be increased, thereby improving the working reliability of the insulator.

[0012] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

[0014] refer to Figure 1-3 .

[0015] The utility model provides an insulator with a positioning function, comprising a disc-shaped body 1, a through hole 10 being provided at the center of the disc-shaped body 1, a first insulating ring 11 and a second insulating ring 12 being provided at the top and bottom of the disc-shaped body 1 respectively, an annular positioning groove 13 being formed between the outer side wall of the second insulating ring 12 and the bottom of the disc-shaped body 1, a third insulating ring 14 being provided at the bottom center of the disc-shaped body 1, an annular groove 15 being provided at the outside of the third insulating ring 14 at the bottom of the disc-shaped body 1, a nut positioning groove 16 being provided at the top center of the disc-shaped body 1 and communicating with the through hole 10, and a longitudinal positioning groove 17 being provided on the side wall of the disc-shaped body 1.

[0016] The principle of its use is that, in order to cooperate with the use of this insulator, a positioning column that matches the longitudinal positioning groove 17 should be set on the fixing plate where the insulator is installed, and a hole position corresponding to the through hole and a limiting ring that matches the annular positioning groove 13 should be opened on the fixing plate. When installing the insulator, the insulator is placed on the fixing plate and the positioning column is engaged with the longitudinal positioning groove 17. The limiting ring will be fitted on the annular positioning groove 13, and a nut that matches its shape is placed on the nut positioning groove 16. Then, the mounting screw is used to connect the hole position, the through hole 10 and the nut to prevent the insulator from rotating on the fixing plate. The insulator can be effectively positioned. By setting the first insulating ring 11, the second insulating ring 12, the annular groove 15 and the third insulating ring 14, the creepage insulation distance between the fixing plate and the mounting screw can be increased, thereby improving the working reliability of the insulator.

[0017] Based on the above embodiment, two longitudinal positioning grooves 17 are symmetrically provided on the side wall of the disc-shaped body 1, which can prevent the insulator from rotating on the fixing plate and improve the positioning effect of the insulator.

[0018] Based on the above embodiment, the nut positioning groove 16 is configured in a regular hexagonal shape. Accordingly, placing a hexagonal nut in the nut positioning groove 16 effectively prevents the insulator from rotating on the fixing plate. The nut positioning groove 16 can also be configured in a regular quadrilateral, regular octagon, or other shape, all of which can achieve the same positioning function, and its shape is not specifically limited.

[0019] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
