[0028] Embodiment 1

[0029] refer to Figure 1-4An anti-interference high-voltage cable comprises an outer sheath 1 and a conductor 11, a docking assembly for connecting two segment conductors 11, the docking assembly comprises a docking sleeve 2 fixedly mounted at the front end of the outer sheath 1, an arc groove 3 is provided on the outer wall of the docking sleeve 2, a clamping groove 7 is provided at the top of the arc groove 3, a first resistance spring 5 is provided at the rear end of the outer sheath 1, a resistance ring 4 is fixedly connected to the rear end of the first resistance spring 5, and a clamping block 6 is fixedly mounted on the outer wall of the outer sheath 1.

[0030] Furthermore: a mounting groove 15 is provided at the rear end of the outer sheath 1, a first resistance spring 5 is fixedly installed at the bottom end of the mounting groove 15, and a resistance ring 4 is slidably mounted on the outer wall of the mounting groove 15. By setting the mounting groove 15 and setting the first resistance spring 5 fixedly installed at the bottom end of the mounting groove 15, the resistance ring 4 is slidably mounted on the outer wall of the mounting groove 15, so that the resistance ring 4 will only slide up and down along the mounting groove 15 during the movement, and will not affect the connection process of the two sections of the cable.

[0031] Furthermore, the specific number of the card blocks 6 and the arc groove 3 is two, and the card blocks 6 and the arc groove 3 are adapted to each other. By setting the specific number of the card blocks 6 and the arc groove 3 to be two, the connection between the two sections of cables is more stable after the two groups of card blocks 6 and the arc groove 3 are engaged with each other, and will not easily loosen.

[0032] During the specific implementation, the user first aligns the contact ring 4 with the docking sleeve 2 and inserts the contact ring 4 into the interior of the docking sleeve 2. During this period, the two clamping blocks 6 need to be aligned with the two arc grooves 3. After alignment, a section of cable needs to be slowly rotated, and the contact ring 4 is pushed into the docking sleeve 2 while rotating. At this time, the clamping block 6 will move along the trajectory of the arc groove 3 until the clamping block 6 is finally inserted into the clamping groove 7. At this time, the contact ring 4 will contact the top of the outer sheath 1, and the elastic force of the first contact spring 5 at the rear end of the contact ring 4 makes the clamping block 6 be pressed against the bottom of the clamping groove 7 and cannot be easily moved without human power. When the clamping block 6 is stuck in the clamping groove 7, the cables at both ends are docked.

[0033] By setting up a docking component, users can quickly dock two sections of cables through the docking component, solving the problem of slow docking between traditional devices. For workers working at heights, reducing the docking time means reducing the working time at heights, increasing the safety of the workers.

[0034] Embodiment 2

[0035] Based on Example 1, refer to Figure 1-4, an anti-interference high-voltage cable, wherein a limiting ring 8 is fixedly installed on the outer wall of the outer sheath 1, one end of the limiting ring 8 is fixedly connected to a second resistance spring 9, and the other end of the second resistance spring 9 is fixedly connected to a protective cover 10, and the protective cover 10 is slidable on the outer wall of the outer sheath 1.

[0036] During specific implementation, before docking the two sections of the cable, the user needs to slide the protective cover 10 towards the limit ring 8. When the protective cover 10 slides to the limit state, the card groove 7 and the arc groove 3 on the outer wall of the docking cover 2 will be exposed to the outside, and the docking can be easily completed at this time. After the two sections of the cable are docked, the user releases the protective cover 10, and the protective cover 10 will be reset by the second resistance spring 9, and the docking cover 2 and the arc groove 3 and the card groove 7 on the outer wall of the docking cover 2 will be protected inside again, so that the docking point of the two sections of the cable will not be easily affected by the external environment, thereby increasing the service life of the cable.

[0037] By providing the limiting ring 8, the second resistance spring 9 and the protective cover 10, after the cables are butted together, the butt joint can be protected inside the protective cover 10, so that the butt joint of the two cable sections will not be easily affected by the external environment, thereby increasing the service life of the cable.

[0038] In addition, a conductor 11 is arranged at the inner center position of the outer sheath 1, an insulating sleeve 12 is fixedly installed on the outer wall of the conductor 11, an inner sheath 13 is fixedly installed on the outer wall of the insulating sleeve 12, and a filler 14 is filled between the outer sheath 1 and the inner sheath 13. The specific material of the insulating sleeve 12 is rubber, the specific material of the inner sheath 13 is stainless steel, and the specific material of the filler 14 is polyethylene. By arranging the insulating sleeve 12 and setting the specific material of the insulating sleeve 12 to be rubber, the insulating sleeve 12 can isolate the conductor 11 from the external environment to prevent current leakage or short circuit. By arranging the inner sheath 13 and setting the specific material of the inner sheath 13 to be stainless steel, the overall tensile strength and compressive strength of the cable are enhanced to extend the service life of the cable. Finally, the specific material of the filler 14 is polyethylene, which can ensure the stable structure and excellent performance of the cable and adapt to different working environments.

[0039] Working principle: the user first aligns the contact ring 4 with the docking sleeve 2, and inserts the contact ring 4 into the interior of the docking sleeve 2. During this period, the two clamping blocks 6 need to be aligned with the two arc grooves 3. After alignment, a section of cable needs to be slowly rotated, and the contact ring 4 is pushed into the docking sleeve 2 while rotating. At this time, the clamping block 6 will move along the trajectory of the arc groove 3 until the clamping block 6 is finally inserted into the clamping groove 7. At this time, the contact ring 4 will contact the top of the outer sheath 1, and the elastic force of the first contact spring 5 at the rear end of the contact ring 4 makes the clamping block 6 be pressed against the bottom of the clamping groove 7 and cannot be easily moved without human power. When the clamping block 6 is stuck in the clamping groove 7, the cables at both ends are docked.

[0040] By setting up a docking component, users can quickly dock two sections of cables through the docking component, solving the problem of slow docking between traditional devices. For workers working at heights, reducing the docking time means reducing the working time at heights, increasing the safety of the workers.

[0041] By providing the outer sheath 1, the inner sheath 13 and the insulating sheath 12, the conductor 11 will not be easily disturbed by the external environment.

[0042] Before docking the two sections of cable, the user needs to slide the protective cover 10 towards the limit ring 8. When the protective cover 10 slides to the limit state, the card groove 7 and the arc groove 3 on the outer wall of the docking cover 2 will be exposed to the outside, and the docking can be easily completed at this time. After the two sections of the cable are docked, the user releases the protective cover 10, and the protective cover 10 will be reset by the second resistance spring 9, and the docking cover 2 and the arc groove 3 and the card groove 7 on the outer wall of the docking cover 2 will be protected inside again, so that the docking point of the two sections of the cable will not be easily affected by the external environment, thereby increasing the service life of the cable.

[0043] By providing the limiting ring 8, the second resistance spring 9 and the protective cover 10, after the cables are butted together, the butt joint can be protected inside the protective cover 10, so that the butt joint of the two cable sections will not be easily affected by the external environment, thereby increasing the service life of the cable.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention.
