[0019] A new type of impact-resistant cable, such as Figures 1 to 3As shown, it includes an outer protective layer 1, which is made of aramid fiber material. Metal shells 2 are arranged on the outside of both ends of the cable. The inside of the metal shell 2 is wrapped with a corrosion-resistant layer 3. The surface of the corrosion-resistant layer 3 is made of a metal wire braided mesh, which can increase the conductivity of the cable core while tightly wrapping the cable core. The inside of the corrosion-resistant layer 3 is wrapped with a buffer layer 4, and the inside of the buffer layer 4 is filled with filling particles 9. The inside of the buffer layer 4 is also provided with six equidistantly arranged buffer bridges 10. The inside of the buffer layer 4 is wrapped with an insulating layer 5, which is made of glass cloth. Since glass cloth has excellent properties such as insulation, heat insulation, corrosion resistance, non-combustibility, high temperature resistance, and high strength, it can increase the structural strength of the entire cable. A wrapping layer 6 is arranged inside the insulating layer 5, and the wrapping layer 6 is made of polyolefin synthetic material. Since polyolefin not only has the characteristics of low relative density, good chemical resistance and water resistance, but also has good mechanical strength and electrical insulation, it can effectively increase the insulation performance of the cable.

[0020] The buffer bridge 10 as a whole is composed of two semicircular elastic rings with opposite opening directions. Buffer springs 11 are arranged in the elastic rings at both ends of the buffer bridge 10. The buffer bridge 10 divides the internal space of the buffer layer 4 into six equal parts. The filling particles 9 are filled between two adjacent buffer bridges 10. The filling particles 9 are restricted inside the buffer layer 4 by six buffer bridges 10. When the cable is impacted from the outside, the two buffer springs 11 inside the buffer bridge 10 will be deformed and compressed for buffering. At the same time, the filling particles 9 between two adjacent buffer bridges 10 will be compressed to reduce external impact.

[0021] A partition plastic 7 is inserted and installed inside the wrapping layer 6, and the surface of the partition plastic 7 is provided with equidistantly arranged wiring slots 8. The number of wiring slots 8 is adapted to the number of cable cores, and the number of wiring slots 8 outside the partition plastic 7 can be customized according to the number of cable cores to be installed. A filling core 12 is installed inside the wiring slot 8. The filling core 12 is an elliptical structure with both sides protruding outward. After the cable is inserted into the corresponding wiring slot 8, the opening of the wiring slot 8 is closed by the filling core 12.

[0022] When installing the cable core, after inserting the cable core into the wiring card slot 8 corresponding to the surface of the partition plastic 7, insert the filling core 12 into the wiring card slot 8 where the cable core is installed. After squeezing the filling core 12 to shrink it into the interior of the wiring card slot 8, install the partition plastic 7 into the interior of the wrapping layer 6. After releasing the filling core 12, the filling core 12 rebounds and fills the opening part of the wiring card slot 8. When the entire cable is subjected to external impact, the filling core 12 will deform and squeeze on the cable core, once again protecting the cable core, so that the entire cable has better impact resistance, greatly improving the service life of the cable.

[0023] The working principle of this utility model:

[0024] A buffer layer 4 is provided, and buffer bridges 10 are equidistantly arranged inside the buffer layer 4. Two buffer springs 11 installed inside the buffer bridge 10 correspond to each other. After the filling particles 9 are filled into the gap between two adjacent buffer bridges 10, the opening part of the buffer layer 4 is closed. When the entire cable is subjected to external impact, the filling particles 9 filled inside the buffer layer 4 will first be squeezed and deformed against each other, reducing the impact force on the cable. At the same time, after the impact is transmitted to the buffer bridge 10, the buffer bridge 10 is compressed again to drive the buffer spring 11 to contract to generate a reverse force for secondary buffering, which greatly reduces the internal impact of the cable when it is impacted, and greatly improves the impact resistance of the cable.

[0025] By providing a cross-shaped filling core 12, when installing the cable core, after the cable core is inserted into the wiring slot 8 corresponding to the surface of the partition plastic 7, the filling core 12 is inserted into the wiring slot 8 where the cable core is installed. After the filling core 12 is squeezed and shrinks into the interior of the wiring slot 8, the partition plastic 7 is installed into the interior of the wrapping layer 6. After the filling core 12 is released, the filling core 12 rebounds and fills the opening part of the wiring slot 8. When the entire cable is subjected to external impact, the filling core 12 will be deformed and squeezed on the cable core, once again protecting the cable core, so that the entire cable has better impact resistance and greatly improves the service life of the cable.

The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
