The sheath group includes a sheath body and a pair of pipe orifices. The sheath body is a sleeve. The sleeve is provided with a slit along the axial direction. Both ends of the slit respectively extend outwards to be provided with oppositely arranged ear plates. A pair of the pipe orifices are respectively symmetrically connected to both ends of the sheath body. The pipe orifices are sleeved on the sheath body. The orifice parts of the pipe orifices correspond to the slit of the sheath body. A plurality of flexibly inserted teeth one are respectively arranged on the opposite surfaces of the orifice parts of the pipe orifices in a staggered manner, forming an inserted tooth group one and an inserted tooth group two; the installation group includes an installation group one and a pair of installation group twos. The installation group one is used to connect the sheath body, and a pair of the installation group twos are respectively used to connect a pair of pipe orifices.

[0004] However, for the existing overhead insulated wires, since their external insulating sheaths are easily affected by thermal expansion and contraction and shorten or elongate, the wrapping stability of their edges around the internal conductive cores is poor, resulting in dislocation of the wire edges, and reducing the sensitivity of the subsequent electrical connection between the conductive cores, thus reducing the utilization rate to a certain extent.

The following describes the embodiments according to the overall structure of the present utility model.

[0024] Please refer to Figures 1 - 2 In the embodiments of the present utility model, an overhead insulated wire with an insulating sheath includes:

[0025] A conducting wire 1 for transmitting electric energy;

[0026] A lower clamping member 2 located outside the conducting wire 1;

[0027] An upper clamping member 3 located on the top of the lower clamping member 2 and outside the conducting wire 1;

[0028] Nuts 4 located on both sides outside the lower clamping member 2 and the upper clamping member 3 and detachably connected to the lower clamping member 2 and the upper clamping member 3;

[0029] Inside the inner side of the wire 1, there is a conductive core 101. Outside the conductive core 101, there is a filling layer, and outside the filling layer, there is an insulating sleeve 102 wrapped. On both sides of the lower clamping part 2 and the upper clamping part 3, there are plug parts 301. On the side of the outside of the plug parts 301 close to the lower clamping part 2 and the upper clamping part 3, there are multiple groups of external threads 302 evenly arranged. On the inner wall of the plug parts 301, there are multiple groups of pressing blocks 303 evenly arranged. At the middle positions of the inner walls of the lower clamping part 2 and the upper clamping part 3, there are multiple groups of pressing teeth 305 evenly arranged. The multiple groups of pressing teeth 305 are arranged in a ring shape. On both sides of one end of the inner wall of the lower clamping part 2, there are winding rods 304.

[0030] Please refer particularly to Figure 1 and 2 , on the side of the inside of the nut 4 close to the lower clamping part 2 and the upper clamping part 3, there are multiple groups of internal threads that match the external threads 302 evenly arranged, and the nut 4 is threadedly connected to the lower clamping part 2 and the upper clamping part 3 through the mutual cooperation of the external threads 302 and the internal threads.

[0031] Please refer particularly to Figure 1 and 2 , one end of the conductive core 101 is spirally wound around the outside of the winding rod 304 and is located inside the lower clamping part 2 and the upper clamping part 3. By using the winding rod 304 to wind part of the conductive core 101, it is used to increase the anti-pressure generated by the conductive core 101 away from the lower clamping part 2 and the upper clamping part 3, thereby reducing the coverage range of the insulating sleeve 102 on the conductive core 101 when affected by thermal expansion and contraction.

[0032] Please refer particularly to Figure 1 and 2 , both the lower clamping part 2 and the upper clamping part 3 are clamped and connected to the conductive core 101 by the pressing teeth 305. By using the pressing teeth 305 to press and support the connection ends of the two conductive cores 101 that are electrically connected, the sensitivity of their subsequent connection is ensured.

[0033] Please refer particularly to Figure 1 and 2 , the plug part 301 is clamped and connected to the insulating sleeve 102 through the pressing block 303, and the pressing block 303 is used for pressing and supporting the outside of the insulating sleeve 102.

[0034] Please refer particularly to Figure 1 and 2 , the outer diameters of the outside of the plug part 301 on the side far from the lower clamping part 2 and the upper clamping part 3 decrease successively toward the side far from the lower clamping part 2 and the upper clamping part 3, which is convenient for inserting the nut 4 along the plug part 301 to both sides of the lower clamping part 2 and the upper clamping part 3, so that the fixing effect of one end of the nut 4 to both sides of the lower clamping part 2 and the upper clamping part 3 is better.

[0035] The working principle of the utility model is as follows: When in use, first, two sets of nuts 4 are respectively inserted outside two sets of wires 1. Then, the conductive cores 101 on the two sets of butt-jointed wires 1 are respectively wound around the corresponding winding rods 304 and are located inside the lower clamping member 2, and one end of the two conductive cores 101 is just located on the end face of the pressing teeth 305. Then, the upper clamping member 3 is sleeved on the top of the lower clamping member 2. At the same time, the nut 4 is moved towards the positions of the lower clamping member 2 and the upper clamping member 3, so that the nut 4 first passes through the plug member 301, and then is sleeved on both sides of the lower clamping member 2 and the upper clamping member 3, and the nut is threadedly connected with the external thread outside the plug member 301, thus the installation can be realized. At the same time, part of the conductive core 101 is wound by the winding rod 304 to increase the anti-pressure generated by the conductive core 101 away from the lower clamping member 2 and the upper clamping member 3, thereby reducing the coverage range of the insulating sleeve 102 on the conductive core 101 when affected by thermal expansion and contraction, and the connecting ends of the two electrically connected conductive cores 101 are pressed and supported by the pressing teeth 305 to ensure the sensitivity of their subsequent connection.

[0036] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacement or change, and should be covered within the protection scope of the utility model.
