[0019] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined utility model purposes, the following is in combination with the preferred embodiments, the specific embodiment, structure, features and effects according to the utility model are described in detail as follows.
[0020] Please refer to Figures 1-4As shown, a pressure-resistant cable includes a cable body 1, which includes a conductor 11, an insulation layer 12, an armor layer 13, an elastic layer 14, a buffer layer 15, a pressure-resistant layer 16, and an outer protective layer 17. The insulation layer 12 is disposed on the outside of the conductor 11. The armor layer 13 is bonded to the side of the insulation layer 12 away from the conductor 11. The elastic layer 14 is bonded to the other side of the armor layer 13. The buffer layer 15 is disposed on the side of the elastic layer 14 away from the armor layer 13. The pressure-resistant layer 16 is made of foamed polyethylene. The foamed polyethylene provides flexibility and elasticity, effectively buffering external impacts, protecting the cable's interior from damage, and also providing good heat insulation and moisture-proof performance, helping to maintain the stability of the cable's internal environment. The pressure-resistant layer 16 is bonded to the outside of the buffer layer 15, and the outer protective layer 17 is bonded to the other side of the pressure-resistant layer 16. Several elastic strips 2 are bonded around the elastic layer 14 and the buffer layer 15, and a filler layer 3 is disposed between adjacent elastic strips 2. The filler layer 3 is made of polypropylene rope. This allows it to effectively fill the gaps inside the cable and shrink when heated, tightly bonding with the other parts of the cable, thereby improving the overall structural stability of the cable.
[0021] The elastic layer 14 is made of polyvinyl chloride (PVC), and the buffer layer 15 is made of polyester tape. The PVC provides sufficient strength and toughness to meet the physical and mechanical performance requirements of the cable during use, thus extending its service life. The polyester tape provides high mechanical strength, effectively resisting tensile and compressive stresses experienced by the cable during installation and use. Furthermore, its flexibility and bendability allow it to adapt to cable bending and torsion, protecting internal components from damage.
[0022] The cable body 1 has a support frame 4 installed inside, and the wire core 11 is in contact with the inner side of the support frame 4. This can protect the adjacent wire cores 11 and prevent them from squeezing each other.
[0023] The outer surface of the outer protective layer 17 is surrounded by several anti-slip ridges 5, which are arranged at equal intervals. This increases the wear resistance of the cable body 1 and extends its service life.
[0024] Working Principle: During use, when the cable body 1 is subjected to external force, the elastic strip 2 deforms under pressure, dispersing the force and achieving a buffering effect. The pressure-resistant layer 16, made of foamed polyethylene, provides flexibility and elasticity, effectively buffering external impacts and protecting the cable's internal structure from damage. It also offers good heat insulation and moisture resistance, helping to maintain a stable internal environment. Simultaneously, the elastic layer 14 and buffer layer 15 provide sufficient strength and toughness to effectively resist tensile, compressive, and other mechanical stresses experienced by the cable during installation and use. Furthermore, its flexibility and ease of bending allow it to adapt to cable bending and torsion, protecting internal components from damage.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
