Description

Technical Field

[0001] This utility model relates to the field of electrical machinery technology, and in particular to a tensile-resistant wire and cable. Background Technology

[0002] With the rapid development of modern industry, energy, transportation, and other fields, the application scenarios of wires and cables are constantly expanding, such as long-distance power transmission for large machinery and equipment. These scenarios place higher demands on the tensile strength of cables. Traditional cables are prone to conductor breakage and insulation damage under long-term tensile or high-intensity use, leading to safety accidents such as short circuits, leakage, and even fires. The application of new high-strength materials has provided a foundation for the research and development of tensile cables. Aramid braided layers are widely used in tensile cables due to their excellent tensile strength and heat resistance.

[0003] Therefore, Chinese patent application number CN217640723 U was filed. This utility model relates to the field of wire and cable technology and discloses a composite tensile-resistant wire and cable, including a cable body. The cable body includes an outer sheath, an elastic sleeve, an armor layer, and an insulating copper core frame. The outer sheath is made of polyvinyl chloride material and has a protective agent coated on its outer surface. Fine mesh wires are embedded inside the outer sheath and are evenly fixed in the interlayer of the outer sheath. An elastic sleeve is provided inside the outer sheath, and the surface of the elastic sleeve has several sets of folds. In this utility model, an elastic sleeve is added inside the outer sheath. The elastic sleeve is made of rubber material. Rubber has good softness and elasticity. With the fold design, its elasticity is further increased, which increases the tensile strength of the cable. An insulating copper core frame is added in the center of the cable to separate the multiple strands of wire that are twisted together, so as to avoid mutual interference between the wires and reduce heat dissipation.

[0004] The aforementioned composite tensile-resistant wire and cable has a simple structure and is easy to operate. However, the tensile strength of this device is slightly weak, which may cause the conductor to break when the cable is repeatedly bent, dragged or subjected to external force, resulting in circuit interruption. The insulation layer may be torn or worn, causing leakage, short circuit or even fire. High-strength materials are needed to enhance the tensile strength. Utility Model Content

[0005] The purpose of this invention is to provide a tensile-resistant wire and cable to solve the problem that existing wires and cables are difficult to withstand tension.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tensile-resistant wire and cable, including a protective structure;

[0007] The protective structure has a tensile structure installed inside, and the tensile structure has a conductor structure installed inside.

[0008] The tensile structure includes a waterproof membrane installed inside the protective structure. The waterproof membrane is made of polyvinyl chloride. The tensile strip is made of polyester fiber. The spiral is made of aramid thread.

[0009] The waterproof membrane is equipped with a tensile strip inside, and a spiral line is provided on the outer wall of the tensile strip. A limit block is installed at one end of the spiral line, and an anti-slip texture is provided at the top of the limit block. A limit groove is formed on the surface of the spiral line.

[0010] Furthermore, a limiting groove is formed on the surface of one end of the tensile strip, and the limiting block and the limiting groove form an engaging structure, which can better position and prevent movement.

[0011] Furthermore, the protective structure includes a first woven mesh on the outside of the tensile structure, and a second woven mesh on the outside of the tensile structure. The material of the first protective sleeve is polyurethane, which has excellent wear resistance.

[0012] Furthermore, the first and second woven meshes intersect each other, forming a mesh structure that enhances internal protection.

[0013] Furthermore, the conductor structure includes a second protective sleeve installed inside the tensile structure, and the second protective sleeve is filled with non-woven fabric, which has good flexibility.

[0014] Furthermore, the nonwoven fabric has a multi-core conductor installed inside, and the surface of the multi-core conductor is provided with an insulating layer to facilitate blocking external interference.

[0015] Furthermore, the waterproof membrane is provided with multiple sets of tensile strips arranged at equal intervals to prevent local breakage.

[0016] The present invention provides a tensile-resistant wire and cable, the advantages of which are: by setting the tensile-resistant wire and cable, the wire and cable can be subjected to a tensile effect, making the effect better, and by setting the tensile-resistant structure, it is easier to achieve a better tensile effect when the wire and cable are subjected to tension.

[0017] By incorporating a tensile structure, the waterproof membrane, made of polyvinyl chloride (PVC), provides protection against the tensile stress on the wires and cables. This material boasts high tensile strength and good flexibility. Because polyester fiber exhibits excellent tensile properties, the tensile strips effectively withstand and disperse tensile force, preventing structural deformation or damage. Therefore, multiple sets of tensile strips are incorporated within the waterproof membrane. By winding spirals around the surface of these strips, friction and wear are reduced, extending their service life. Limiting blocks prevent excessive displacement of the tensile strips under tensile force, ensuring the overall stability and safety of the structure.

[0018] By incorporating a conductor structure, the second protective sleeve, made of silicone rubber, provides protection for the inside of the cable during tensile testing. Non-woven fabric serves as the filling material, cushioning the impact of external mechanical forces on the multi-core conductor and preventing damage during bending, twisting, or pulling, thus extending the cable's service life.
