[0002] Network cables, generally made of metal or glass, are used to transmit information within a network. There are three common types of network cables: twisted pair, coaxial cable, and fiber optic cable (fiber optic). Twisted pair is a data transmission line composed of many pairs of wires. Its advantage is its low price, so it is widely used.

[0003] With the development of society, the performance requirements of network cables in outdoor network environments are getting higher and higher. When network cables are used outdoors, they are affected by a variety of external environmental factors.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] like Figure 1As shown, a double-shielded outdoor network cable includes a protective sleeve 1, which protects the internal layered structure. The outer surface of the protective sleeve 1 is provided with an anti-oxidation layer 2, and the outer surface of the anti-oxidation layer 2 is provided with an anti-bite layer 3. The inside of the protective sleeve 1 is provided with a tensile layer 4, the inside of the tensile layer 4 is provided with a reinforcing layer 5, the inside of the reinforcing layer 5 is provided with a waterproof layer 6, the inside of the waterproof layer 6 is provided with a heat-resistant layer 7, the inside of the heat-resistant layer 7 is provided with a first shielding layer 8, the inside of the first shielding layer 8 is provided with a moisture-proof layer 9, and the inside of the moisture-proof layer 9 is provided with a plurality of second shielding layers 10. Each of the plurality of second shielding layers 10 is provided with a wire core 11, and the wire core 11 inside the second shielding layer 10 consists of two wires twisted together.

[0021] As an optional technical solution of this utility model, the protective sleeve 1 is made of polyurethane. Polyurethane has good chemical resistance, resilience and mechanical properties, which makes the protective sleeve 1 have a better protective effect.

[0022] As an optional technical solution of this utility model, the material of the antioxidant layer 2 is EPDM rubber. EPDM rubber has excellent properties in terms of heat resistance, ozone resistance, weather aging resistance, low temperature resistance, electrical insulation, acid resistance, and alkali resistance, thus making the antioxidant layer 2 have good antioxidant properties.

[0023] As an optional technical solution of this utility model, the anti-bite layer 3 is made of cyclohexylamine and organotin compounds. The anti-bite layer 3 is coated on the outer surface of the antioxidant layer 2 to form a protective layer. It has an irritating effect on rodents such as mice and can effectively prevent rodents from attacking the plant.

[0024] As an optional technical solution of this utility model, the tensile layer 4 is made of tensile fiber, and the reinforcing layer 5 is made of thermoplastic polyurethane elastomer. Thermoplastic polyurethane elastomer has advantages such as high strength, high elasticity, and wear resistance. The reinforcing layer 5 makes the outdoor network cable more elastic, and the thermoplastic polyurethane elastomer has high tear strength and high abrasion resistance. In combination with the tensile layer 4, the tensile performance of the outdoor network cable is better, avoiding damage to the outdoor network cable caused by bending and stretching.

[0025] As an optional technical solution of this utility model, the waterproof layer 6 is made of epoxy resin. Epoxy resin is a thermosetting plastic with excellent waterproof, moisture-proof and insulating properties. It can form a hard waterproof layer through chemical reaction, effectively protecting the outdoor network cable from the damage of the humid environment. The moisture-proof layer 9 is made of silicone. Silicone is a porous solid containing a large number of micropores and channels. These micropores and channels can absorb and store a large amount of moisture, thus making the moisture-proof layer 9 have a good moisture-proof and moisture-absorbing effect. Through the waterproof layer 6 and the moisture-proof layer 9, the waterproof box of the outdoor network cable has a good moisture-proof effect.

[0026] As an optional technical solution of this utility model, the heat-resistant layer 7 is made of Teflon. Teflon is a high-performance plastic material with an extremely high temperature resistance range and excellent chemical stability. It can maintain stable performance in extreme high temperature and corrosive environments, making the heat-resistant layer 7 have good heat resistance and preventing the outdoor network cable from oxidizing due to high external temperatures.

[0027] As an optional technical solution of this utility model, the first shielding layer 8 is a tin-plated copper wire braided mesh. The tin-plated copper wire braided mesh has high conductivity and shielding effectiveness, and can effectively isolate electromagnetic waves. The second shielding layer 10 is made of aluminum foil. Aluminum foil has excellent conductivity, shielding effectiveness and corrosion resistance, and can adapt to various requirements. It can shield high-frequency electromagnetic waves. Through the dual electromagnetic shielding function, the influence of external electromagnetic waves on the outdoor network cable can be avoided, and the normal transmission function of the outdoor network cable can be guaranteed.

[0028] In summary, this double-shielded outdoor network cable exhibits excellent anti-oxidation performance through the anti-oxidation layer 2, good tensile strength and elasticity through the tensile layer 4 and reinforcing layer 5, good waterproof and moisture-proof performance through the combination of the waterproof layer 6 and moisture-proof layer 9, and good heat resistance through the heat-resistant layer 7. These features effectively mitigate the impact of external environmental factors on the cable, preventing breakage. The anti-bite layer 3 prevents rodents and other rodents from damaging the cable, thus ensuring its lifespan and guaranteeing the stability and reliability of network transmission. Furthermore, the dual shielding function of the first shielding layer 8 and the second shielding layer 10 significantly reduces the impact of external interference signals, further ensuring the stability and reliability of network transmission.
