[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

The top and bottom of the limiting block 701 both penetrate the moving hole 5 and extend to the outside of the inner cavity of the moving hole 5. The opposite sides of the two limiting blocks 701 are fixedly connected to the outer shell 702, and the opposite sides of the two limiting blocks 701 are fixedly connected to the spring 703. The opposite sides of the two springs 703 are fixedly connected to the inner cavity of the moving hole 5.

[0023] With the above solution, by providing the limiting device 7 , when the first insulated wire 1 and the second insulated wire 2 need to be connected, the limiting device 7 has a limiting effect on the positions of the first insulated wire 1 and the second insulated wire 2 .

[0024] refer to Figure 3 The inner cavity of the outer shell 702 is movably connected to the inner shell 8 , and the side of the inner shell 8 close to the inner cavity of the moving hole 5 is fixedly connected to the inner cavity of the moving hole 5 .

[0025] By adopting the above solution: by setting the inner shell 8, when the limit block 701 moves, it will drive the outer shell 702 to move along the surface of the inner shell 8. The cooperation between the inner shell 8 and the outer shell 702 has a limiting effect on the moving position of the limit block 701.

[0026] refer to Figure 1 The surface of the rotating rod 6 away from the limiting block 701 is movably connected with a control rotating plate 9.

[0027] The above solution is adopted: by providing the control rotating plate 9 , when the control rotating plate 9 rotates along the surface of the rotating rod 6 , the extrusion hole 10 can be driven to rotate along the surface of the extrusion frame 11 .

[0028] refer to Figure 4 An extrusion hole 10 is provided on the surface of the control rotating plate 9 , and an extrusion frame 11 used in conjunction with the extrusion hole 10 is fixedly connected to the top of the limit block 701 , and the inner cavity of the extrusion hole 10 is movably connected to the inner cavity of the extrusion frame 11 .

[0029] The above solution is adopted: by providing the extrusion hole 10 and the extrusion frame 11, the extrusion hole 10 can produce extrusion on the extrusion frame 11, and the extrusion frame 11 subjected to the extrusion force can drive the limit block 701 to move.

[0030] refer to Figure 2 and Figure 3 The front and rear sides of the bottom of the metal mounting block 3 are fixedly connected with a plug rod 12, and the front and rear sides of the top of the metal mounting shell 4 are provided with a plug hole 13 used in conjunction with the plug rod 12, and the surface of the plug rod 12 is in contact with the inner cavity of the plug hole 13.

[0031] The above solution is adopted: by setting the plug rod 12 and the plug hole 13, when the metal mounting block 3 moves, the plug rod 12 will be driven to move into the inner cavity of the plug hole 13. The coordinated use of the plug rod 12 and the plug hole 13 has a limiting effect on the moving position of the metal mounting block 3.

[0032] refer to Figure 2 The left and right sides of the metal mounting shell 4 are both provided with limiting grooves 14 used in conjunction with the limiting block 701 , and the surface of the limiting block 701 contacts the inner cavity of the limiting groove 14 .

[0033] The above scheme is adopted: by setting the limit groove 14, when the surface of the metal mounting block 3 contacts the inner cavity of the metal mounting shell 4, and the plug-in rod 12 moves to the inner cavity of the plug-in hole 13, the control turn plate 9 is released, and the force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 14. The coordinated use of the limit block 701 and the limit groove 14 has a limiting effect on the position of the metal mounting block 3 and the metal mounting shell 4.

[0034] The working principle of this utility model:

[0035] When in use, when it is necessary to connect the overhead insulated wires conveniently and stably, the user first rotates the control turn plates 9 to the opposite side of the two control turn plates 9, driving the control turn plates 9 to rotate along the surface of the rotating rod 6. When the control turn plates 9 rotate, the extrusion hole 10 will be driven to rotate along the surface of the extrusion frame 11. The extrusion frame 11 subjected to the extrusion force will move to the side away from the metal mounting block 3. When the extrusion frame 11 moves, it will drive the two limit blocks 701 to move away from each other. When the limit blocks 701 move, it will drive the outer shell 702 to move along the surface of the inner shell 8. The force generated when the limit blocks 701 move causes the spring 703 to undergo elastic deformation. When the two limit blocks 701 move away from each other, Move the first insulated conductor 1 toward the bottom. When the first insulated conductor 1 moves, it will drive the metal mounting block 3 and the plug rod 12 to move toward the bottom. When the plug rod 12 is completely moved to the inner cavity of the plug hole 13 and the surface of the metal mounting block 3 contacts the inner cavity of the metal mounting shell 4, release the control turn plate 9. The force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck in the inner cavity of the limit groove 14. The coordinated use of the limit block 701 and the limit groove 14 has a limiting effect on the position of the metal mounting block 3 and the metal mounting shell 4. The coordinated use of the metal mounting block 3 and the metal mounting shell 4 has a limiting effect on the position of the first insulated conductor 1 and the second insulated conductor 2. At this time, the overhead insulated conductors complete a convenient and stable connection.

[0036] To sum up: the overhead insulated conductor that is easy to connect solves the problem that special connectors or clamps are usually used to connect overhead insulated conductors by setting a limit device 7, a limit block 701, an external shell 702, a spring 703 and a limit groove 14. The connection process needs to ensure that the connector can be firmly fixed on the insulated conductor while maintaining a good electrical connection. The existing connectors or clamps use bolts to adjust the tightness for positioning. It takes a long time to adjust the tightness of the bolts, which is not convenient enough. The bolts used in the insulated conductors are prone to rust and aging due to long-term exposure to the air, resulting in unstable installation. However, the existing overhead insulated conductors do not have a component for convenient and stable connection.
