In addition, it should be noted that only the parts related to the utility model are shown in the drawings for ease of description.
[0021] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments
[0022] As shown in Figure 1 , a high-voltage electric wire connecting sleeve is composed of a connecting pipe 1, a silica gel strip 10, an anti-falling tooth 11, a split groove 12, a fixed strip 13, a movable groove 14, a first connecting ring 2, an anti-falling ring a 20, a second connecting ring 3, an anti-falling ring b 30, a copper pipe 4, a copper sheet 40, a gasket 5, etc.
[0023] As Figure 1 and Figure 2 shown, the outer diameter of the connecting pipe 1 at both ends is provided with threads, which can be conveniently connected. The two ends of the connecting pipe 1 can be divided into several fixed strips 13 by the split groove 12. The inner side of each fixed strip 13 is provided with a silica gel strip 10, and the two sides of the silica gel strip 10 are arc-shaped. By adjusting the first connecting ring 2 and the second connecting ring 3, the silica gel strips 10 can be abutted with each other and abutted on the wire on the inner side to prevent rainwater from entering and causing electric leakage. The anti-loose teeth 11 are arranged at both ends of the copper pipe 4, and the copper pipe 4 is fixed in the middle of the connecting pipe 1. A circular copper sheet 40 is fixed to the inner wall of the copper pipe 4. When the wire enters from both ends of the connecting pipe 1, it needs to pass through the silica gel strip 10, the anti-loose tooth 11 and the copper pipe in turn, and finally abut on the copper sheet 40 to make the two conduct electricity. Adjusting the first connecting ring 2 and the second connecting ring 3 makes the anti-loose teeth 11 penetrate into the insulating tube of the wire, which can prevent the wire from falling off. The middle of the outer diameter of the connecting pipe 1 is provided with a movable groove 14, which can prevent the first connecting ring 2 and the second connecting ring 3 from falling off.
[0024] As Figure 2 and Figure 3 shown, the first connecting ring 2 is provided with an anti-loose ring a20 at one end; the second connecting ring 3 is provided with an anti-loose ring b30 at one end, and the open ends of the first connecting ring 2 and the second connecting ring 3 are arranged at the other end and arranged opposite to each other. The inner diameter of the first connecting ring 2 and the second connecting ring 3 is provided with threads, which can be matched with the threads on the outer diameter of the two ends of the connecting pipe 1 respectively. At the same time, the first connecting ring 2 and the second connecting ring 3 make the silica gel strip 10 and the anti-loose tooth 11 abut on the wire and clamp tightly. The inner side of the anti-loose ring a20 and the anti-loose ring b30 corresponds to the two sides of the movable groove 14, and the inner side of the anti-loose ring a20 and the anti-loose ring b30 is provided with a gasket 5. When the first connecting ring 2 and the second connecting ring 3 are tightened, the gasket 5 abuts on both sides of the movable groove 14 to prevent rainwater from entering. The inner side of the anti-loose ring a20 and the anti-loose ring b30 is also provided with a gasket groove, and a gasket 5 is arranged in each gasket groove. The gasket groove is conducive to the fixation of the gasket 5 and prevents it from falling off.
[0025] The above description is only the preferred embodiment of the present application and the explanation of the technical principle and other schemes used. Meanwhile, the utility model range involved in the present application is not limited to the technical scheme formed by the specific combination of the above technical features, and should also cover other technical schemes formed by any combination of the above technical features or equivalent features without departing from the utility model concept. For example, the technical scheme formed by replacing the above features with the technical features disclosed in the present application (but not limited to) having similar functions.
