Technical Field

[0001] The present application relates to the technical field of wires and cables, and in particular to a long-life, high-performance wire and cable. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts, one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] Ordinary wires and cables are made of traditional PVC plastic, which has certain shortcomings in terms of waterproofing, fireproofing, and moisture resistance. Special industries such as firefighting place particularly high demands on cables, such as maintaining normal operation for a certain period of time during a fire. In addition to high temperatures, firefighting also involves external mechanical impacts and water jets. In such an environment, wires and cables must be able to withstand multiple destructive tests to maintain circuit integrity. Failure to do so will directly affect the quality and service life of the wires and cables. Summary of the Invention

[0004] In order to solve the problem that existing wires and cables are subjected to external mechanical impacts and fire-fighting water sprays in addition to high temperature in the event of a fire, in this environment, in order to maintain the integrity of the circuit, the wires and cables must be able to withstand multiple destructive tests, otherwise it will directly affect the quality and service life of the wires and cables. The present application provides a long-life high-performance wire and cable.

[0006] A long-life, high-performance wire and cable comprises a first wire bundle and a plurality of second wire bundles arranged at equal intervals in the circumferential direction of the first wire bundle, a plurality of positioning components for fixing the second wire bundles are arranged at equal intervals on the outside of the first wire bundle, a protective component is arranged on the outside of the positioning component, a protective cover is arranged on the outside of the protective component, and an anti-deformation component is arranged on the outside of the protective cover to enhance the cable's anti-deformation ability.

[0007] Preferably, the positioning assembly includes a positioning sleeve, a positioning cavity is defined inside the positioning sleeve, and the positioning cavity is filled with silicone rubber.

[0008] Preferably, one side of the positioning sleeve is provided with a plurality of elastic strips, and the other side is provided with a plurality of strip grooves matching the elastic strips, and both the elastic strips and the strip grooves adopt an isosceles trapezoidal structure.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] See also Figures 1 to 6 , the present invention provides a technical solution:

[0024] A long-life, high-performance wire and cable comprises a first wire bundle 1 and a plurality of second wire bundles 2 equidistantly arranged in a circumferential direction of the first wire bundle 1. A plurality of positioning components 3 for fixing the second wire bundles 2 are equidistantly arranged on the outside of the first wire bundle 1, a protective component 4 is arranged on the outside of the positioning component 3, a protective cover is arranged on the outside of the protective component 4, and an anti-deformation component 5 is arranged on the outside of the protective cover to enhance the cable's anti-deformation ability.

[0025] During use, when the cable is subjected to external force or impact, the anti-deformation component 5 is set on the outer layer, and it will first be subjected to the external force, and then transmitted to the protective cover and the positioning component 3 in turn, to disperse the impact force and absorb the impact force in turn, and avoid the external force being directly transmitted to the internal first wire bundle 1 and the second wire bundle 2, thereby enhancing the cable's anti-deformation ability and avoiding affecting the internal first wire bundle 1 and the second wire bundle 2. At the same time, by setting the protective cover, the cable's waterproof, flame retardant and moisture-proof performance can be improved, so that the cable can work normally in special environments and continue to maintain the integrity of the circuit, thereby improving the quality and service life of the wires and cables.

[0026] The positioning component includes a positioning sleeve 6, a positioning cavity 7 is opened inside the positioning sleeve 6, and the positioning cavity 7 is filled with silicone rubber 8. The positioning sleeve is used to separate the first wire bundle and the second wire bundle, which can avoid rotational twisting between the first wire bundle 1 and the second wire bundle 2. When the cable is subjected to external force or impact, it will be transmitted to the positioning sleeve 6, and the positioning sleeve 6 will squeeze the silicone rubber 8 to cause deformation, thereby absorbing the impact force and avoiding affecting the normal operation of the first wire bundle 1 and the second wire bundle 2 inside.

[0027] A plurality of elastic strips 9 are provided on one side of the positioning sleeve 6, and a plurality of strip grooves 10 matching the elastic strips 9 are provided on the other side. Both the elastic strips 9 and the strip grooves 10 adopt an isosceles trapezoidal structure. The protective component 4 includes a protective layer 11 arranged on the outside of the positioning sleeve 6, and a plurality of rubber blocks 12 adapted to the positioning sleeve 6 are arranged at equal intervals on the inside of the protective layer 11. By matching the elastic strips 9 and the strip grooves 10 with each other, the positions of the plurality of positioning sleeves 6 are limited, making it difficult for them to slide.

[0028] The protective cover includes an insulating layer 13 , a flame retardant layer 14 , a waterproof layer 15 and a wear-resistant layer 16 which are sequentially installed on the outside of the protective layer 11 .

[0029] The outer surface of the wear-resistant layer 16 is provided with a plurality of anti-slip protrusions 17 .

[0030] It should be noted that the insulating layer 13 is made of silicone rubber, the flame retardant layer 14 is made of polyvinyl chloride material, the waterproof layer 15 is made of water-blocking tape, and the wear-resistant layer 16 is made of polyurethane material, which makes the cable more waterproof and fire-resistant, and has good buffering and shock-absorbing effects, a long service life, and is suitable for environments with higher working temperatures.

[0031] The anti-deformation component includes a plurality of outer insulating connecting strips 19 arranged at equal intervals on the outside of the wear-resistant layer 16, a rubber sleeve 18 installed at the other end of the outer insulating connecting strip 19, and an anti-deformation cable 20 fixedly wrapped in the rubber sleeve 18. When the cable is subjected to external force or impact, the anti-deformation cable 20 is the first to be subjected to tension, which can prevent the tension from being transmitted to the internal cable. The rubber sleeve 18 is provided to protect the anti-deformation cable 20.
