[0041] Example 1 Reference Figures 1 to 4 A cable clamping and insertion structure includes: an outer sleeve 1, a sealing tube 2, a tightening tube 3, and a gasket 4 sequentially sleeved on the cable 5, wherein the cable holes of the outer sleeve 1, the sealing tube 2, and the tightening tube 3 are coaxially arranged.
[0042] The first end of the wire hole of the outer tube 1 is provided with a first end connection hole 101, the first end connection hole 101 is provided with a first internal thread, and the end of the first end connection hole 101 is provided with a sealing hole 102.

[0049] Both the outer sleeve 1 and the tightening sleeve 3 are equipped with external hexagonal sockets, which facilitates the use of wrenches and other auxiliary tools for assembly operations.
[0050] In this application, the tightening tube 3 and the outer tube 1 can be connected by screwing, thereby pressing the sealing tube 2 into the sealing hole 102. The inner diameter of the first end of the sealing hole 102 is larger than the inner diameter of the last end, that is, it is conical. As the sealing tube 2 is pressed, the sealing performance gradually improves, so that the sealing tube 2 and the sealing hole 102 fit tightly, ensuring the sealing performance, effectively preventing water immersion, improving equipment safety, and reducing losses.
[0051] Example 2 Reference Figure 5 A cable clamping and insertion structure includes: an outer sleeve 1, a sealing tube 2, a tightening tube 3, and a gasket 4 sequentially sleeved on the cable 5, wherein the cable holes of the outer sleeve 1, the sealing tube 2, and the tightening tube 3 are coaxially arranged.

[0053] The inner wall of the wire hole of the outer tube 1 is provided with a tightening opening 103. The inner diameter of the tightening opening 103 is smaller than the diameter of the cable 5.

[0056] The difference between Embodiment 2 and Embodiment 1 is that the first end of the sealing tube 2 does not have a stepped ring 201, nor does it have a first annular groove or a first sealing ring 202. This structural design allows the sealing tube 2 to be better squeezed into the sealing hole 102 after the tube 3 is tightened, which helps to improve the sealing performance of the sealing tube 2 and the sealing tube 2 and its end with the outer sleeve 1, thereby improving the sealing and waterproof performance.
[0057] The end of the tightening tube 3 is provided with a first external thread 301, which is threadedly engaged with the first internal thread provided in the first end connecting hole 101.
[0058] Gasket 4 is a Teflon gasket. Gasket 4 is fitted onto the cable 5 between the tightening tube 3 and the sealing tube 2. Teflon gaskets have good properties such as corrosion resistance, aging resistance and non-conductivity. The setting of gasket 4 helps to maintain a good sealing effect.
[0059] Both the outer sleeve 1 and the tightening sleeve 3 are equipped with external hexagonal sockets, which facilitates the use of wrenches and other auxiliary tools for assembly operations.
[0060] In this application, the tightening tube 3 and the outer tube 1 can be connected by screwing, thereby pressing the sealing tube 2 into the sealing hole 102. The inner diameter of the first end of the sealing hole 102 is larger than the inner diameter of the last end, that is, it is conical. As the sealing tube 2 is pressed, the sealing performance gradually improves, so that the sealing tube 2 and the sealing hole 102 fit tightly, ensuring the sealing performance, effectively preventing water immersion, improving equipment safety, and reducing losses.

[0063] The inner wall of the wire hole of the outer tube 1 is provided with a tightening opening 103. The inner diameter of the tightening opening 103 is smaller than the diameter of the cable 5. With the setting of the tightening opening 103, after the tightening tube 3 is tightened, the end of the outer sheath of the cable 5 can abut against the tightening opening 103, which helps to improve the sealing performance and prevent the wire hole of the outer tube 1 from being soaked in water.
[0064] The difference between Embodiment 3 and Embodiment 1 is that the end of the outer tube 1 is not provided with a second external thread 104, nor with a second annular groove or a second sealing ring 105.

The first sealing ring 202 is tightly fitted with the outer tube 1. By setting the stepped ring 201, the sealing structure of the first annular groove and the first sealing ring 202 can be set together, which is beneficial to improving the sealing performance between the first end of the sealing tube 2 and the outer tube 1, thereby improving the sealing and waterproof performance.
[0067] The end of the tightening tube 3 is provided with a first external thread 301, which is threadedly engaged with the first internal thread provided in the first end connecting hole 101.
