[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables. Wires and cables mainly include bare wires, electromagnetic wires, insulated wires for motors and electrical appliances, power cables, communication cables, and optical cables.

[0003] Existing wires and cables lack high-overlapping wrapping and high-density filling layer support for the internal components of the conductor, making them prone to misalignment. They also lack a high-rigidity armor layer and anti-slip textured structure on the outer layer, making them prone to tangling when subjected to external force or when multiple wires are in contact. In response to this technical problem, this application proposes an anti-tangling wire and cable. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing cables that are prone to tangling when pulled by external forces. It proposes an anti-tangling wire and cable, which features a core conductor wound at a spiral angle to prevent loosening, a middle layer of wrapping tape and a high-density filler layer to ensure coaxial alignment of components, an outer armor layer for torsion resistance, and an outer rubber sheath for anti-slip and anti-friction properties.

An insulating shielding layer is tightly fitted to the inner wall of the copper tape shielding layer. An inner insulating sleeve is fitted and disposed inside the insulating shielding layer. A conductor shielding layer is fitted to the inner wall of the inner insulating sleeve. An intertwined metal conductor is wrapped inside the conductor shielding layer. The intertwined metal conductor is formed by multiple strands of tinned copper wire interlaced at a helix angle of 20°.

[0006] Furthermore, the outer protective rubber sleeve has a thickness of 1.5-2.5mm, and the outer surface is integrally formed with an arc-shaped anti-slip texture with a texture spacing of 3-5mm.

[0007] Furthermore, the armor layer is made of galvanized steel wire woven from steel wire with a diameter of 0.3-0.5 mm, a weaving density of not less than 90%, and the gaps between the steel wires are filled with waterproof silicone.

[0008] Furthermore, the inner sheath has a thickness of 1.0-1.8 mm, and the inner wall of the inner sheath is uniformly coated with a high-temperature resistant epoxy resin adhesive with a thickness of 0.05-0.1 mm.

[0009] Furthermore, the strap is a flame-retardant non-woven fabric strap, which is wrapped around the inner side of the inner sheath in an overlapping manner, with an overlap rate of 50% during wrapping, and the tensile strength of the strap is not less than 20MPa.

[0010] Furthermore, the filling layer is made of flame-retardant glass fiber rope with a filling density of 0.8-1.2 g / cm³. 3 Furthermore, the surface of the fiberglass rope is impregnated with flame retardant.

[0011] Furthermore, the copper strip shielding layer is made of annealed soft copper strip with a thickness of 0.1-0.2mm, and is attached to the inner side of the filling layer by spiral wrapping with a wrapping pitch of 15-25mm.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an anti-tangle wire and cable, comprising an outer sheath rubber sleeve 1, an armor layer 2, an inner sheath 3, a wrapping tape 4, a filling layer 5, and three sets of copper tape shielding layers 6 arranged coaxially from the outside to the inside. The inner sidewall of the outer sheath rubber sleeve 1 is tightly fitted to the outer sidewall of the armor layer 2. The inner side of the armor layer 2 completely wraps the inner sheath 3. The inner side of the inner sheath 3 is fixed by spiral winding of the wrapping tape 4. The annular gap between the inner side of the wrapping tape 4 and the outer side of the copper tape shielding layer 6 is filled with a filling layer 5. The inner sidewall of the copper tape shielding layer 6 is tightly fitted with an insulating shielding layer 7. An inner insulating sleeve 8 is sleeved and provided on the inner side of the insulating shielding layer 7. A conductor shielding layer 9 is fitted to the inner sidewall of the inner insulating sleeve 8. An intertwined metal conductor 10 is wrapped inside the conductor shielding layer 9. The intertwined metal conductor 10 is formed by interlacing multiple strands of tin-plated copper wires at a spiral angle of 20°. Specifically, the multi-strand tinned copper wires of the intertwined metal conductor 10 are interlaced at a 20° helix angle, which not only ensures the stability of current transmission but also prevents the single strand of wire from becoming loose and twisted; the flame-retardant non-woven fabric wrapping tape 4 is wrapped with a 50% overlap rate and has a tensile strength of over 20MPa, which can firmly fix the inner sheath 3 and the internal components and prevent displacement.

[0017] The outer sheath 1 is 2.5mm thick, with an integrally formed anti-slip texture in an arc shape on the outer surface, and the texture spacing is 5mm. The armor layer 2 is made of galvanized steel wire braided with a diameter of 0.5mm and a braiding density of not less than 90%, and the gaps between the steel wires are filled with waterproof silicone. The inner sheath 3 is 1.8mm thick, and the inner wall of the inner sheath 3 is uniformly coated with a high-temperature resistant epoxy resin adhesive with a thickness of 0.1mm. The wrapping strap 4 is a flame-retardant non-woven fabric wrapping strap, which is wrapped around the inner side of the inner sheath 3 in an overlapping manner, with an overlap rate of 50%, and the tensile strength of the wrapping strap is not less than 20MPa. The filling layer 5 is made of flame-retardant fiberglass rope with a filling density of 1.2g / cm³. 3 Furthermore, the surface of the fiberglass rope is impregnated with flame retardant, and the copper strip shielding layer 6 is made of annealed soft copper strip with a thickness of 0.2mm. It is attached to the inner side of the filling layer 5 by spiral wrapping with a wrapping pitch of 25mm. Specifically, filler layer 5 uses a filler density of 1.2 g / cm³. 3Furthermore, flame-retardant fiberglass rope impregnated with flame retardant fills the gap between the wrapping tape 4 and the copper tape shielding layer 6, ensuring that the three sets of copper tape shielding layers 6 are coaxial and orderly. The copper tape shielding layer 6, made of annealed soft copper tape, is spirally wrapped with a wrapping pitch of 25mm, which serves both shielding and stabilizing functions. The armor layer 2 is woven with galvanized steel wire with a density of ≥90% and the gaps are filled with waterproof silicone, which enhances the cable's resistance to external tensile forces and achieves waterproofing. The arc-shaped anti-slip texture of the outer rubber sheath 1 reduces friction and prevents tangling, while also facilitating gripping and maintenance. The inner sheath 3 is 1.8mm thick, with a 0.1mm thick high-temperature resistant epoxy resin adhesive on the inner side, which tightly adheres to the wrapping tape 4, strengthening the interlayer connection and enabling the cable to operate stably in complex environments, ensuring anti-tangling and practical performance.

[0018] Working principle: The internal intertwined metal conductor 10 is formed by multiple strands of tin-plated copper wires interlaced at a 20° helical angle, ensuring flexibility while preventing the wires from loosening and twisting, thus reducing entanglement sources from the core layer. The inner sheath 3 is spirally wrapped with flame-retardant non-woven fabric tape with an overlap rate of 50%, and is further filled with a high-density flame-retardant fiberglass rope filling layer 5 to fill the gap between the wrapping tape 4 and the copper tape shielding layer 6. This ensures that the three sets of copper tape shielding layers 6 and the internal components are coaxially and neatly arranged, preventing local entanglement caused by component misalignment. The outer armor layer 2, made of galvanized steel wire, enhances structural rigidity and reduces torsion caused by external pulling. The outermost arc-shaped anti-slip textured rubber sleeve 1 reduces the coefficient of friction between cables to avoid contact and entanglement. At the same time, the anti-slip texture facilitates gripping and positioning during handling. The high-temperature resistant epoxy resin adhesive on the inner side of the inner sheath also strengthens the fit between the wrapping tape 4 and the inner sheath 3, maintaining the overall structural stability. Ultimately, it achieves all-round anti-entanglement from the inside out, while also taking into account flame retardant, waterproof, and high-temperature resistance properties, making it suitable for complex usage scenarios.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
