Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable resistant to biting. Background Technology

[0002] Cables are an indispensable part of power systems, used to transmit electrical energy from power plants or substations to users, enabling long-distance or short-distance power transmission. They carry high voltage and high current, distributing electricity to various industrial and agricultural production units and users, forming a power transmission and distribution system. In the communications field, they are used to transmit telephone, television, data, and network signals. Fiber optic cables can transmit data at high speed and with high capacity in the form of optical signals, serving as a crucial support for modern communication networks. In the construction field, cables are used for power and signal transmission within buildings, such as electrical wires, network cables, and television cables, ensuring the normal operation of electrical equipment within the building. In the industrial field, cables connect various production equipment, enabling power and signal transmission and ensuring the normal operation of production lines. In the transportation field, cables are used for power and signal transmission in transportation vehicles such as subways and high-speed trains.

[0003] However, in existing cables, due to severe damage from rodents and insects, irritant materials are usually added to prevent rodents and insects from damaging them. However, after long-term use, the outer sheath of the cable will be damaged, so the damaged area cannot produce irritant molecules and thus becomes vulnerable to rodents and insects. In addition, the connection points of existing rodent-proof cables are usually poorly protected, and the outer sheath and armor layer at the connection point can be damaged by construction workers during connection, so the probability of the connection point being damaged by gnawing is high, and the sealing and pull-resistant properties of the connection point are not strong. Utility Model Content

[0004] The purpose of this invention is to provide a bite-resistant cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0020] A type of anti-gnawing cable includes an inner threaded sleeve 101, with connecting mechanisms 102 at both ends of the inner threaded sleeve 101. The connecting mechanism 102 includes an outer threaded sleeve 103, with a cable mechanism 104 disposed inside the outer threaded sleeve 103. The inner threaded sleeve 101 is fixedly installed on the front side of the outer threaded sleeve 103. A first sealing gasket 105 is fixedly installed at the connection between the outer threaded sleeve 103 and the inner threaded sleeve 101. A first limiting block 106 is fixedly installed on the front side of the outer threaded sleeve 103. A connecting clip 201 is fixedly installed on the rear end of the outer threaded sleeve 103.

[0021] The above scheme allows the internal threaded sleeve to connect the external threaded sleeve in series and seal the cable connection. The first sealing gasket keeps the connection between the internal threaded sleeve and the external threaded sleeve sealed. The first limiting block keeps the external threaded sleeve in a limited position and facilitates tightening. The connecting clips clamp the wire core.

[0022] In this embodiment, preferably, the connecting mechanism 102 further includes an internal threaded cylinder 202, which is fixedly installed on the outside of the external threaded cylinder 103, and a second sealing gasket 203 is fixedly installed at the connection between the internal threaded cylinder 202 and the external threaded cylinder 103.

[0023] The above solution allows for the encapsulation of the connecting clip by installing the internal threaded barrel and the external threaded barrel, and the second sealing gasket ensures that the installation point of the internal threaded barrel and the external threaded barrel remains sealed.

[0024] In this embodiment, preferably, a second limiting block 204 is fixedly installed at the front end of the internal threaded cylinder 202, a support tube 205 is fixedly installed at the rear end of the internal threaded cylinder 202, a threaded clamp tube 206 is fixedly installed at the rear end of the internal threaded cylinder 202 outside the support tube 205, and a locking nut 301 is fixedly installed on the outside of the threaded clamp tube 206.

[0025] The above scheme uses the second limiting block to limit the installation of the internal threaded barrel and facilitates the tightening of the internal threaded barrel. The support tube can provide support inside the outer sheath. The locking nut connected to the threaded clamp tube can cause the threaded clamp tube to contract and clamp the outer sheath onto the support tube.

[0026] In this embodiment, preferably, the cable mechanism 104 includes an outer sheath 302, an armor layer 303 is fixedly installed on the inner side of the outer sheath 302, a waterproof layer 304 is fixedly installed on the inner side of the armor layer 303, and a flame-retardant layer 305 is fixedly installed on the inner side of the waterproof layer 304.

[0027] The above solutions utilize an outer sheath to generate irritating molecules, preventing rodents and insects from gnawing on the cable. The armor layer provides secondary protection, preventing rodents and insects from penetrating the cable's interior. Furthermore, the armor layer prevents electromagnetic interference, improving the stability of signal transmission. The waterproof layer enhances the cable's waterproof performance, and the flame-retardant layer prevents or delays the spread of flames, thus improving the cable's fire safety.

[0028] In this embodiment, preferably, an inner sheath 306 is fixedly installed inside the flame-retardant layer 305, an inner protective layer 401 is fixedly installed inside the inner sheath 306, and an anti-pull rope 402 is fixedly installed inside the inner protective layer 401.

[0029] The above solution, by using the same material for the inner and outer sheaths, provides final protection for the cable, preventing damage from external factors that could allow rodents and insects to gnaw on it. The inner sheath increases internal flexibility, cushioning the core when compressed, and the anti-drop rope improves the cable's tensile strength.

[0030] In this embodiment, preferably, a main wire core 403 is fixedly installed in the middle of the inner sheath 401, a main wire insulation layer 404 is fixedly installed on the outside of the main wire core 403, an auxiliary wire core 405 is fixedly installed around the inside of the inner sheath 401, and an auxiliary wire insulation layer 406 is fixedly installed on the outside of the auxiliary wire core 405.

[0031] The above scheme allows signal transmission through the main wire core and auxiliary wire core. The main wire insulation layer insulates the main wire core, and the auxiliary wire insulation layer insulates the auxiliary wire core.

[0032] In this embodiment, the anti-gnawing cable uses an outer sheath 302 made of polyethylene. Polyethylene has excellent physical properties and chemical stability, resisting the biting of rodents and insects and environmental erosion. It also possesses good flexibility and plasticity, facilitating cable bending and installation. Furthermore, during extrusion production, it is compounded by adding materials such as capsaicin, camphor, or o-isopropylphenyl methyl carbamate, resulting in an outer sheath with a highly irritating composition that effectively stimulates the taste buds of rodents and insects, causing them to reject the cable and thus preventing them from gnawing on it. The armor layer 303 is located inside the outer sheath 302. 2. After damage occurs, the armor layer 303 provides secondary protection. Made of woven steel wire, the armor layer 303 possesses high strength and hardness, effectively resisting rodent and insect bites while preventing electromagnetic interference and improving signal transmission stability. The waterproof layer 304, made of polyamide, has excellent waterproof and chemical corrosion resistance, effectively preventing external moisture intrusion. The flame-retardant layer 305 uses flame retardants such as halides and metal oxides to achieve a flame-retardant effect, preventing or delaying the spread of flames and improving the cable's fire safety. The inner sheath uses the same material as the outer sheath 302, providing the final layer of protection inside the cable. The rodent and insect protection measures, with a thickness relatively thinner than the outer sheath 302, aim to prevent secondary damage from rodents and insects when the cable is severely damaged, thus preventing damage to the internal wire cores and leakage. When connecting the two sets of cables in series at the cable break, the break points are trimmed to expose the main wire core 403 and auxiliary wire core 405, which are then connected inside the external threaded sleeve 103. After connection, the inner threaded sleeve 101 is connected to the external threaded sleeve 103 to clamp the first sealing gasket 105 and protect the wire core connection. Then, the main wire core 403 and auxiliary wire core 405 are engaged in the connecting clip 20. 1. The connecting clip 201 is made of soft metal, so when it is pressed together, the main wire core 403 and the auxiliary wire core 405 can be clamped and fixed. After the wire cores are fixed, the user connects the internal threaded barrel 202 and the external threaded barrel 103 and clamps the second sealing gasket 203. After clamping, the user snaps the outer sheath 302 between the support tube 205 and the threaded clamp tube 206, and installs the locking nut 301 on the outside of the threaded clamp tube 206 to clamp and fix the outer sheath 302. After fixing, the cable connection is sealed, thus ensuring the protection of the cable connection and preventing the generation of irritating molecules at the joint to achieve the effect of preventing rodent and insect gnawing.
