[0028] As described in the background section, existing cables have weak anti-interference capabilities and low tensile strength, which shortens their service life.

[0029] To solve this technical problem, this utility model provides a special cable with high tensile strength, which is applied to special cables with high tensile strength.

[0030] For details, please refer to Figure 1- Figure 3 Special cables with high tensile strength specifically include:

[0031] The inner protective frame 2 has multiple conductor components 3 arranged in a ring array around its periphery. The inner protective frame 2 is used to limit and fix the conductor components 3.

[0032] The inner protective frame 2 includes a tensile frame body 7. The tensile frame body 7 has the same number of fastening slots 11 as the conductor assembly 3 on its periphery. The conductor assembly 3 is located inside the fastening slots 11. The inner protective frame 2 is fastened to the conductor assembly 3 through the fastening slots 11. Several side bending slots 12 are evenly opened on both sides of the inner protective frame 2. Several side bending slots 23 are evenly opened on the top and bottom of the inner protective frame 2. Tensile strips 8 are fixedly connected to the outer side of the inner protective frame 2 at the position between every two adjacent fastening slots 11.

[0033] The outer protective layer 1 is fitted on the outside of the inner protective frame 2 and is used to protect the inner protective frame 2 and the conductor assembly 3.

[0034] The special cable with high tensile strength provided by this utility model has a simple cable structure through the combination of multiple structures, which effectively ensures the strength of the cable, and gives the cable good anti-interference performance and insulation, effectively extending the service life of the cable, greatly improving the reliability of the cable operation, and making it easy to use and promote.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figure 1 - Figure 3 A special cable with high tensile strength, comprising:

[0038] The inner protective frame 2 has multiple conductor components 3 arranged in a ring array around its periphery. The inner protective frame 2 is used to limit and fix the conductor components 3.

[0039] Specifically, the inner protective frame 2 includes a tensile frame body 7. The tensile frame body 7 has the same number of fastening slots 11 as the conductor assembly 3 on its periphery. The conductor assembly 3 is located inside the fastening slots 11. The inner protective frame 2 is fastened to the conductor assembly 3 through the fastening slots 11. Several side bending slots 12 are evenly opened on both sides of the inner protective frame 2. Several side bending slots 13 are evenly opened on the top and bottom of the inner protective frame 2. Tensile strips 8 are fixedly connected to the outer side of the inner protective frame 2 at the position between every two adjacent fastening slots 11. It can be seen that the buckle groove 11 opened by the tensile frame 7 can realize the buckling and limiting of the conductor assembly 3, reducing the occurrence of accidental twisting or displacement of the conductor assembly 3. Furthermore, the side bending groove 12 opened on the side of the tensile frame 7 and the side bending groove 13 opened on the top and bottom can provide protection for the conductor assembly 3 while also having a certain degree of bending effect. The tensile frame 7 can improve the tensile strength of the cable, and the tensile strip 8 fixed on the outside of the tensile frame 7 can further improve the tensile strength of the cable.

[0040] The outer protective layer group 1 is sleeved on the outside of the inner protective frame 2 and is used to protect the inner protective frame 2 and the conductor assembly 3. Specifically, the outer protective layer group 1 includes a metal shielding layer 4, a tensile braided layer 5 is sleeved on the outside of the metal shielding layer 4, and an outer protective layer 6 is sleeved on the outside of the tensile braided layer 5. The inner protective frame 2 and the conductor assembly 3 are both located inside the metal shielding layer 4.

[0041] The outer sheath 6 is made of rubber. This effectively ensures the cable's insulation and provides good wear resistance and protection.

[0042] The tensile braided layer 5 is made of nickel-chromium alloy wire, which effectively blocks external electromagnetic interference and protects the stable transmission of signals inside the cable. In high-frequency signal transmission or applications requiring high anti-interference capabilities, the tensile braided layer 5 provides reliable electromagnetic shielding, ensuring signal integrity and accuracy. The braided layer, composed of multiple fine nickel-chromium alloy wires interwoven, provides additional mechanical strength to the cable. It resists external physical damage such as pressure, pulling, and scratching, thus protecting the internal protective frame 2 and conductor assembly 3 from damage. This mechanical protection helps extend the cable's service life and improve its reliability and durability.

[0043] Example 2:

[0044] The high tensile strength special cable provided in Example 1 is further optimized, specifically, as follows: Figure 2 As shown, the conductor assembly 3 includes a conductor body 9, and an insulating layer 10 is fitted on the outer side of the conductor body 9. The insulating layer 10 provides protection for the conductor body 9.

[0045] Example 3:

[0046] The high tensile strength special cable provided in Example 1 is further optimized, specifically, as follows: Figures 2-3 As shown, both the tensile frame 7 and the tensile strip 8 are made of plastic. The tensile frame 7 is hollow.

[0047] Through the above structural design, the hollow tensile support 7 can reduce the weight of the cable and facilitate molding through extrusion, making it easy to produce.
