There are two springs 13, and the two springs 13 are symmetrically distributed inside the sealing box 10. The end of the spring 13 away from the piston block 12 is fixedly connected to the sealing box 10. A first through hole 14 is provided on the surface of the sealing box 10. A protective layer 4 is fixedly arranged on the side of the sealing box 10 away from the cable core 1. A second through hole 5 is provided on the surface of the protective layer 4.

The protective layer 4 made of wear-resistant rubber can effectively reduce the wear of the sealing box 10 and extend the service life of the cable. The cable with an anti-interference structure provides an electromagnetic shielding function through the first anti-interference layer 6 made of conductive tape, and the copper The second anti-interference layer 7 made of foil provides the function of shielding high-frequency interference signals. When the outside is squeezed, the sealing box 10 is pushed to move toward the cable core 1, so that the piston block 12 moves inside the sealing box 10, squeezes the gas inside the sealing box 10, and discharges it through the first through hole 14. At the same time, because the gas inside the sealing box 10 is discharged slowly, the gas is squeezed to form a force in the outward direction, reducing the pressure on the waterproof layer 8, and then reducing the pressure on the first anti-interference layer 6 and the second anti-interference layer 7. The spring 13 is used to push the sealing box 10 back to its original position. The cable has a certain anti-interference function, which ensures the use of the cable, and at the same time can reduce the pressure on the anti-interference layer and avoid damage to the anti-interference layer.
[0021] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

It is discharged to the outside of the protective layer 4. At the same time, because the gas inside the sealing box 10 is discharged slowly, the gas is squeezed to form a force in the outward direction, reducing the pressure on the waterproof layer 8, and then reducing the pressure on the first anti-interference layer 6 and the second anti-interference layer 7. When the sealing box 10 moves downward, it will squeeze the spring 13 and the elastic block 9 at the same time.

When the outside is squeezed, the sealing box 10 is pushed to move in the direction of the cable core 1, so that the piston block 12 moves inside the sealing box 10, squeezes the gas inside the sealing box 10, and discharges it through the first through hole 14. At the same time, because the gas inside the sealing box 10 is discharged slowly, the gas is squeezed to form a force in the outward direction, reducing the pressure on the waterproof layer 8, and then reducing the pressure on the first anti-interference layer 6 and the second anti-interference layer 7. The rebound action of the spring 13 pushes the sealing box 10 back to its original position. The cable has a certain anti-interference function, which ensures the use of the cable, and at the same time can reduce the pressure on the anti-interference layer and avoid damage to the anti-interference layer.
