Embodiment 1

[0029] Please refer to figure 1 and figure 2 , a preferred embodiment of the present invention provides an insulating sleeve, which mainly includes a sleeve body 10 made of insulating material and a soft fastening sleeve 20 .

[0030] Please continue to refer to figure 1 and figure 2 , the sleeve body 10 is a hollow cylinder structure with an opening at one end, specifically a cylindrical cylinder structure, which has a coaxial hollow interior, and the opening is opened at one end and communicates with the hollow interior. The bushing body 10 is made of insulating material. In this preferred embodiment, the bushing body 10 is made of ABS plastic, which has a certain hardness and strength, and has a good insulating effect.

[0031] The soft fastening sleeve 20 is arranged in the hollow inside of the sleeve body 10. The fastening sleeve 20 is made of foamed cotton. The foamed cotton has a good insulating effect, and has good softness, and is easy to squeeze after extrusion....

Embodiment 2

[0039] The difference from Example 1 is that please refer to image 3 and Figure 4 , in this preferred embodiment, the insulating sleeve also includes a damage prevention part 50, the damage prevention part 50 includes an open circuit piece 51 and a pull-out strip 52, the open circuit piece 51 is a circular sheet structure, and one end surface thereof is convex arc surface, the opposite end surface is a concave arc surface, and the edge of the concave arc surface is provided with a pull-out bar 52. In this preferred embodiment, the pull-out bar 52 is a thin rod-shaped structure with a certain strength and hardness , relatively slender, the edge size of the open piece 51 is larger than the hollow interior dimension of the fastening sleeve 20 and can be squeezed into the hollow interior of the fastening sleeve 20 . Considering that the live wire head of the front line may be a sharp structure, when it is inserted into the fastening sleeve 20, it may deflect and pierce or pierc...

Embodiment 3

[0041] The difference from Example 1 is that please refer to Figure 5 , in this preferred embodiment, the opening end of the sleeve body 10 is a conical structure with a large portion close to the opening and a small portion away from the opening, and the sleeve body 10 is grooved radially at the conical structure to The conical structure is divided into a multi-lobe structure. In this preferred embodiment, the fastening sleeve 20 extends to the opening of the sleeve body 10 and has the same slot so that it is also a multi-lobe structure at its end. , the outer circumference of the sleeve body 10 is provided with external threads near the opening end, and the outer circumference of the sleeve body 10 is covered with a threaded sleeve 60, the threaded sleeve 60 has a matching internal thread and is installed on the sleeve by threads On the body 10, and when the threaded sleeve 60 moves toward the opening end of the sleeve body 10 of the multi-lobe structure, it can squeeze the...

Abstract

The insulating sleeve comprises a sleeve body made of an insulating material, the sleeve body is of a hollow cylinder structure with an opening in one end, a soft fastening sleeve is arranged in the hollow interior of the sleeve body, and the fastening sleeve is of a hollow cylinder structure with an opening in one end. And the opening of the fastening sleeve and the opening of the sleeve body are in the same direction and are communicated with each other. According to the insulating sleeve provided by the invention, after the meter front wire is detached, the insulating sleeve can be directly sleeved on the live wire head of the meter front wire for shielding, the insulating shielding of the meter front wire can be realized, the insulating sleeve provided by the invention is simple in structure, simple in insulating shielding operation, good in insulating effect and not easy to fall off, and the insulating shielding performance is greatly improved; and the electric shock risk is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance devices, in particular to an insulating sleeve. Background technique [0002] When the 400V and below switches and electric energy meters are repaired and replaced, it is often necessary to dismantle and replace the switch before the meter. After the front wire of the meter is removed, the existing insulation shielding method is to wrap the insulating tape on the exposed For necessary temporary insulation at the core of the cable. However, there are certain deficiencies in this method. For example, it is easy to get an electric shock and difficult to operate during the implementation of insulation shielding by means of insulating tape. At the same time, in freezing weather, the effect of insulating tape is not good and it is easy to fall off, resulting in poor insulation shielding effect. Well, if it is serious, it will even endanger the personal safety of the operator. Conte...
