[0039] An insulating plug adaptable to multiple cable specifications includes a cable accessory body 10, an insulating plug body 20 connected to the cable accessory body 10, and a cable 30.

[0040] The cable accessory body 10 and the insulating plug body 20 are connected by a threaded connection. Specifically, the cable accessory body 10 has an external thread (not shown in the figure) at its tail end, and the insulating plug body 20 has an internal thread (not shown in the figure) at end A. End A of the insulating plug body 20 is connected to the tail end of the cable accessory body 10 by a threaded connection. The insulating plug body 20 includes an insulating seat 21, a reducing clamping device 22 connected to the insulating seat 21, an adjusting device 23 sleeved on the reducing clamping device 22, and an insulating head 24 sleeved on the insulating seat 21. The insulating seat 21 includes a control part 211 and an insulating part 212 connected to the control part 211. The control part 211 has a hexagonal cross-section, the insulating part 212 has a step 2121 inside, and an external thread 212A is provided on the outer wall of the insulating part 212. Here, the cross-sectional shape of the control unit 211 is hexagonal, so that the insulating base 21 can be turned by means of the control unit 211 and external tools, which improves the convenience of operation.

[0041] The variable diameter clamping device 22 includes a variable diameter body 221 and an inclined variable diameter head 222 connected to the variable diameter body 221. The variable diameter body 221 is provided with a variable diameter groove 22A along a preset direction. The variable diameter head 222 is disposed at one end of the variable diameter body 221. The variable diameter groove 22A also passes through the variable diameter head 222. The bottom of the variable diameter body 221 abuts against the step 2121 to limit the variable diameter clamping device 22. Furthermore, the variable diameter head 222 is arranged in a ring on the variable diameter body 221. The adjusting device 23 includes an adjusting part 231 and a limiting part 232 connected to the adjusting part 231. The limiting part 232 is arranged in a ring shape at one end of the adjusting part 231. The adjusting part 231 has a conical adjusting hole 2311 inside. The reducing head 222 cooperates with the conical adjusting hole 2311. The limiting part 232 has a wire passage hole 2321, which is connected to the conical adjusting hole 2311. It should be noted that the diameter of the wire passage hole 2321 is the maximum diameter of the cable 30 that can be connected to the insulating plug of this application, and the minimum diameter of the cable 30 that can be connected is the minimum diameter after the reducing head 222 has changed diameter. Here, the limiting part 232 is provided so that, in extreme cases, the E surface of the limiting part 232 corresponds to the B end of the insulating seat 21, and the adjusting part 231 is physically limited in a timely manner, so as to prevent the adjusting part 231 from exceeding the limit and causing the wire clamping device 22 to pass through the adjusting device 23. In addition, the diameter changing head 222 is an inclined diameter changing head 222, so as to achieve a smoother fit between the inclined surface of the diameter changing head 222 and the arc surface of the conical adjusting hole 2311, and avoid interference between related structures at a 90° angle.

[0042] The inner wall of the insulating head 24 is provided with an internal thread 24A, which mates with the external thread 212A on the outer wall of the insulating part 212 to achieve the connection between the insulating head 24 and the insulating part 212. Simultaneously, the interior of the insulating head 24 is also provided with a lower pressure plate 241, which abuts against the F-face of the limiting part 232 to achieve the connection between the insulating head 24 and the insulating part 212 via the threaded connection. The mutual cooperation between the two drives the adjustment device 23 to move, thereby enabling the variable diameter clamping device 22 to clamp the cable 30. In addition, the insulating head 24 is also provided with a wire passage hole 2321, which is on the same straight line as the wire passage hole 2321, the conical adjustment hole 2311, the variable diameter body 221, and the insulating seat 21 on the limiting part 232. The cable 30 passes through the wire passage hole 2321, the conical adjustment hole 2311, the variable diameter body 221, and the insulating seat 21 respectively, and is connected to the interior of the cable accessory body 10.

[0043] Here, the cable accessory body 10, the insulating plug body 20 connected to the cable accessory body 10, and the cable 30 are included. The insulating plug body 20 includes an insulating seat 21, a diameter-changing clamping device 22 connected to the insulating seat 21, an adjusting device 23 sleeved on the diameter-changing clamping device 22, and an insulating head 24 sleeved on the insulating seat 21. The diameter-changing clamping device 22 includes a diameter-changing body 221 and an inclined diameter-changing head 222 connected to the diameter-changing body 221. The adjusting device 23 includes an adjusting part 231 and a limiting part 232 connected to the adjusting part 231. The adjusting part 231 has a conical adjusting hole 2311 inside. The diameter-changing head 222 cooperates with the conical adjusting hole 2311. The cable 30 is connected to the cable accessory body 10 through the insulating plug body 20. This allows the insulating plug to adapt to cables 30 of different diameters within a certain range during use, effectively improving the adaptability and ease of operation of the insulating plug.

[0044] To facilitate understanding, the working principle of this application is further described as follows: An insulating plug adaptable to multiple cable specifications 30 is used. During the connection process between the cable 30 and the cable accessory body 10, the cable 30 first passes through the insulating plug body 20 before connecting to the cable accessory body 10. During the passage through the insulating plug body 20, the cable 30 sequentially passes through the insulating head 24, the adjusting device 23, the reducing clamp device 22, and the insulating seat 21. The length of the cable 30 extending beyond the insulating seat 21 is determined according to actual needs. By manually rotating the insulating head 24, the insulating head 24 pushes the adjusting device 23, and the cable 30 moves through the conical adjusting hole 21. With the cooperation of 311 and the reducing head 222, the reducing body 221 and the reducing head 222 clamp the cable 30 that passes through, making the cable 30 unable to move freely. Finally, the outer sheath of the cable 30 extending out of the insulating seat 21 is partially peeled off, thereby exposing the core of the cable 30. The connection between the cable accessory body 10 and the insulating plug body 20 is achieved through the cooperation between the external thread (not shown in the figure) at the tail end of the cable accessory body 10 and the internal thread (not shown in the figure) at end A of the insulating plug body 20. At the same time, the core of the cable 30 is also connected to the cable accessory body 10.
