Description

Technical Field

[0001] The utility model relates to the technical field of circuit insulation, and particularly to an insulator for increasing creepage distance. Background Art

[0002] The creepage distance refers to the minimum distance required between two conductors along the surface of the insulating material on the surface of the insulating material. This distance is to prevent current from flowing on the surface of the insulating material, resulting in short circuits or electrical failures. The size of the creepage distance is affected by the properties of the material, environmental conditions, and operating voltage.

[0003] And an insulator for increasing creepage distance is disclosed in Chinese Patent Publication No. CN215731119U. The patented technology is provided with a bidirectional screw and an insulating tube. The bidirectional screw is rotatably connected inside the insulating tube, so as to facilitate the stable adjustment of the distance between the adjusting plates, and then adjust and control the distance between the insulating plates, which is convenient to use;

[0004] However, through the specification and the specification drawings of the above patented technology, it can be seen that when the above patented technology is specifically implemented, it mainly adjusts the distance between the insulating plates through a threaded rod to increase the creepage distance. This way of increasing the creepage distance is relatively single, and a large number of fixed joints need to be installed inside the insulating tube for cooperative adjustment, resulting in a relatively complex production process of the device. At the same time, the insulating tube also needs to be broken when adjusting the insulating plates, which will also affect the insulation performance of the insulating plates. Therefore, there are still deficiencies when the above patented technology is specifically implemented.

[0005] In summary, it is very necessary to invent an insulator for increasing creepage distance. Utility Model Content

[0024] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0025] Refer to the attached Figures 1-5 , a kind of insulating part for increasing the creepage distance provided by the present utility model includes an insulating tube 100. Insulators 220 are slidably connected to both the upper and lower ends of the outer wall of the insulating tube 100. Threading holes can be opened on both the upper and lower sides of the outer wall of the provided insulator 220 for wire harnesses to pass through. Through holes are opened at the centers of both the upper and lower ends of the outer wall of the insulator 220. The insulator 220 is slidably connected to the outer wall of the insulating tube 100 through the through holes. The through holes are provided to enable the insulator 220 to slide up and down on the outer wall of the insulating bolt 200. Guide slide bars 222 are fixed to the inner walls of the through holes.

The outer walls of the guide slide bars 222 are slidably connected to the inner walls of the adjusting chutes 110. The provided guide slide bars 222 and adjusting chutes 110 are used to guide the up and down sliding of the insulator 220 on the outer wall of the insulating tube 100;

[0026] An adjusting component for adjusting the creepage distance is provided on the insulator 220. The adjusting component includes insulating bolts 200. Multiple insulating bolts 200 are evenly arranged in an annular array. The upper and lower ends of the outer wall of the insulating bolt 200 are fixedly connected to the side end of the outer wall of the insulating tube 100 through fixing blocks. The other end of the provided fixing block can be fixed to the side end of the outer wall of the insulating tube 100 by screws or other fixing methods. Through holes 223 are formed at the upper and lower sides of the outer wall of the insulator 220 and at positions corresponding to the insulating bolts 200. Multiple through holes 223 are evenly arranged in an annular array. The through holes 223 are all arranged outside the through holes. The outer walls of the insulating bolts 200 are slidably connected to the inner walls of the through holes 223. Locking nuts 210 are threadedly connected to the outer walls of the insulating bolts 200 and are located on the upper and lower sides of the insulator 220. Specifically, the provided insulating bolts 200 can pass through the two insulators 220 through the through holes 223, and by turning the locking nuts 210, the positions of the insulators 220 on the outer walls of the insulating bolts 200 can be adjusted up and down, so that the creepage distance between the two insulators 220 can be increased. The provided insulating bolts 200 and locking nuts 210 can be prepared using insulating materials;

[0027] The outer wall of the insulator 220 is provided with an insulation reinforcement component, which includes an annular protrusion 221. Multiple annular protrusions 221 are fixed integrally to the outer side of the insulator 220. Multiple annular protrusions 221 are evenly arranged in a strip array. The annular protrusions 221 can increase the area of the outer wall of the insulator 220, thereby increasing the creepage distance of the insulating bolt 200. The outer wall of the insulator 220 and between two adjacent annular protrusions 221 are fixed with an insulating ring 230, and the insulating ring 230 can be made of insulating material. The insulating ring 230 can interrupt the current flow of the outer wall of the insulator 220, thereby increasing the insulation effect of the outer wall of the insulator 220 and improving the creepage distance. The insulating ring 230 includes two semicircular ring bodies 231, which are clamped on the side ends of the outer wall of the insulator 220 and are located between the annular protrusions 221. Screw holes 232 are opened on both sides of the outer wall of the insulating ring 230. The outer wall side ends of the semicircular ring bodies 231 are threadedly connected with locking screws through the inner walls of the screw holes 232. The semicircular ring bodies 231 are fixedly connected to the outer wall of the insulator 220 through the locking screws. The joints of the semicircular ring bodies 231 are respectively fixed with connecting blocks 233 and connecting slots 234. The connecting blocks 233 are slidably plugged into the inner walls of the connecting slots 234 at the corresponding positions. Specifically, personnel can align the two semicircular ring bodies 231 and snap them into the insulator 220. The outer wall is located between the annular protrusions 221, and then the locking screw is taken out and passed through the screw hole 232 to be fixed to the outer wall of the insulator 220. In the two semi-circular bodies 231, the connecting plug 233 and the opened connecting slot 234 are staggered, that is, when the personnel align the two semi-circular bodies 231, the set connecting plug 233 can be inserted into the corresponding connecting slot 234, so that the two semi-circular bodies 231 can be fixed on the outer wall of the insulator 220.

[0028] The use process of the utility model is as follows: first, the personnel can screw the inner locking nut 210 into the outer wall of the insulating bolt 200, and the personnel can slide the insulator 220 to the outer wall of the insulating tube 100 through the through hole, and at the same time, the insulating bolt 200 can pass through the insulating bolt 200 through the through hole 223, and the guide slide bar 222 is aligned and slid with the adjustment slide groove 110, and then the outer locking nut 210 is taken out and the locking nut 210 is rotated on the insulating bolt 200, and the upper and lower ends of the insulating bolt 200 are connected to the upper and lower sides of the outer wall of the insulating tube 100 through the fixing block;

[0029] The position of the insulator 220 on the insulating bolt 200 can be adjusted by the operator turning the locking nut 210, so that the creepage distance between the insulators 220 can be adjusted. After completion, the operator can also align and snap the two semi-circular bodies 231 on the outer wall of the insulator 220 and between the annular protrusions 221. Then, the locking screw is taken out and fixed to the outer wall of the insulator 220 after passing through the screw hole 232. Among the two semi-circular bodies 231, the connecting plug 233 and the connecting slot 234 are arranged in a staggered manner. That is, when the operator aligns the two semi-circular bodies 231, the connecting plug 233 can be inserted into the corresponding connecting slot 234, so that the two semi-circular bodies 231 can be fixed on the outer wall of the insulator 220, thereby further adjusting the creepage distance of the insulator 220 as needed.
