Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable wire resistant to folding deformation. Background Art

[0002] Electric wires and cables refer to materials used for power, electrical and related transmission purposes. There is no strict boundary between "electric wires" and "cables". Generally, products with fewer cores, smaller product diameters and simpler structures are called electric wires, those without insulation are called bare wires, and others are called cables. Most traditional cable wires are installed through simple insulating bushings. Since multiple conductor groups inside the cable wire are connected together without gaps, it will be damaged when the cable wire is arranged and bent. At the same time, it is difficult to waterproof, insulate and short-circuit the conductors of the cable wire in harsh high-altitude environments, and it is necessary to enhance the insulation and water isolation performance, thereby reducing the use effect.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figures 1-3 The utility model provides a folding and deformation-resistant cable, comprising a cable body 101, an outer sheath 102 is fixedly sleeved on the inner wall of the cable body 101, a PVC insulating layer 103 is fixedly sleeved on the inner wall of the outer sheath 102, an inner liner 104 is connected to the inner wall of the PVC insulating layer 103, four waterproof sheaths 105 are arranged inside the inner liner 104, an elastic conductor 107 is arranged inside the inner liner 104, an insulating filling layer 106 is arranged between the four waterproof sheaths 105, and an anti-folding component is connected to the inner wall of the waterproof sheath 105, which enhances the deformation of the cable body 101, with reference to Figure 1 The anti-folding component includes a silicone rubber layer 108 fixedly connected to the inner wall of the waterproof sheath 105, a heat-resistant PVC layer 109 fixedly connected to the inner wall of the silicone rubber layer 108, an elastic layer 200 fixedly connected to the inner wall of the heat-resistant PVC layer 109, and a tensile filling fiber 202 is arranged between the elastic layer 200 and the inner sheath 201, and the tensile filling fiber 202 plays a role in strengthening the anti-extrusion of the inner sheath 201.

[0025] The waterproof sheath 105 is provided with an inner sheath 201, and the inner wall of the inner sheath 201 is connected with an insulating component. Figure 1 The insulating component includes a polyethylene insulating layer 203 fixedly connected to the inner wall of the inner sheath 201, a shielding layer 204 fixedly connected to the inner wall of the polyethylene insulating layer 203, a polyvinyl chloride sheath 205 fixedly connected to the inner wall of the shielding layer 204, a polyester transparent film 206 fixedly connected to the inner wall of the polyvinyl chloride sheath 205, and a plurality of pure oxygen-free copper cores 207 are arranged inside the polyester transparent film 206. The polyethylene insulating layer 203, the shielding layer 204 and the polyvinyl chloride sheath 205 play an insulating role on the pure oxygen-free copper core 207.

[0026] Working principle: When in use, first, the polyester transparent film 206 protects multiple pure oxygen-free copper cores 207 and blocks the erosion of electricity. Then, the polyvinyl chloride sheath 205 insulates and prevents electricity for the multiple pure oxygen-free copper cores 207. Next, the shielding layer 204 effectively prevents external electromagnetic interference and reduces the electromagnetic radiation of the cable itself. At the same time, the polyethylene insulation layer 203 blocks the erosion of electricity of the pure oxygen-free copper cores 207. Then, the inner sheath 201 again plays a role in protecting and insulating the pure oxygen-free copper cores 207, ensuring the insulation and electricity prevention effect.

[0027] When the cable line body 101 is arranged and bent, the bending strength between the elastic wire 107 and the enhanced waterproof sheath 105 is increased. At the same time, the outer sheath 102 blocks the erosion of external rainwater. Then, the PVC insulation layer 103 again blocks the erosion of rainwater and insulates and prevents electricity. At the same time, the inner lining sleeve 104 protects the four waterproof sheaths 105 again and blocks the erosion of rainwater. And the elastic wire 107 blocks the four waterproof sheaths 105 from contacting each other. At the same time, the tensile filling fiber 202 strengthens the bending strength of the cable line body 101. At the same time, the silicone rubber layer 108 enhances the strength and resilience of the cable line body 101. Then, the heat-resistant PVC layer 109 blocks the erosion of rainwater and the combustion caused by a short circuit in the circuit. Then, the elastic layer 200 again strengthens the bending strength of the cable line body 101, ensuring the anti-bending effect.
