Description

Technical Field

[0001] The utility model belongs to the technical field of communication optical cables, and in particular relates to an anti-bite underground communication optical cable. Background Art

[0002] Communication optical cable is a communication line that uses a certain number of optical fibers to form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath, to achieve optical signal transmission. Communication optical cable has a larger transmission capacity than copper cable, a longer relay section, a smaller size, a lighter weight, and no electromagnetic interference. It has now developed into a wired transmission line backbone for long-distance trunk lines, urban relays, offshore and transoceanic submarine communications, as well as local area networks and private networks, and has begun to develop into the field of urban user loop distribution networks, providing transmission lines for fiber-to-the-home and broadband integrated digital services networks.

[0003] At present, the existing underground communication optical cables are often bitten by rats or reptiles underground because they are buried deep underground, causing the outer sheath of the optical cable to be bitten, exposing the internal optical fiber and contacting the underground soil, causing damage or breakage of the optical cable, affecting the transmission of signals. For this reason, we propose an anti-bite underground communication optical cable. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-bite underground communication optical cable to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chew-proof underground communication optical cable, comprising an inner sheath, a cavity and a main thorn needle, the outer sheath of the inner sheath is provided with a second plastic-coated steel belt, the outer sheath of the second plastic-coated steel belt is provided with a wire mesh, a plurality of rubber linings are provided between the wire mesh and the second plastic-coated steel belt, a cavity is formed between two adjacent rubber linings, a main thorn needle is provided inside the cavity, one end of the main thorn needle is fixedly connected to the outer peripheral surface of the second plastic-coated steel belt, the top of the main thorn needle does not contact the wire mesh, and a plurality of auxiliary thorn needles are provided on the periphery of the main thorn needle.

[0006] Preferably, an outer sheath is provided on the outside of the wire mesh, and the outer sheath fixedly covers the outer circumference of the wire mesh.

[0007] Preferably, a first plastic-coated steel strip is provided inside the inner sheath, and the first plastic-coated steel strip is in close contact with the inner wall surface of the inner sheath.

[0008] Preferably, a plurality of sleeves are provided inside the first plastic-coated steel strip, and optical fibers are provided inside the sleeves.

[0009] Preferably, a water-blocking grease is provided between the sleeve and the first plastic-coated steel strip, and the water-blocking grease is filled in the gap between the sleeve and the first plastic-coated steel strip.

[0010] Preferably, fiber oil paste is provided between the sleeve and the optical fiber, and the fiber oil paste is filled in the gap between the sleeve and the optical fiber.

[0011] Preferably, a reinforcement piece is provided at the inner center of the first plastic-coated steel strip, and the sleeve is arranged around the reinforcement piece.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting a cavity between the inner sheath and the outer sheath, and setting a main stinger and a secondary stinger on the outside of the second plastic-coated steel belt, when the outer sheath is damaged by biting, the main stinger and the secondary stinger will be exposed, causing stabbing to the biting mice or reptiles, causing them to feel pain and stop biting, thereby achieving the purpose of anti-biting and ensuring the stable use of optical fiber.

[0014] 2. By setting a wire mesh on the inner wall of the outer sheath, the strength of the outer sheath is increased, and the bracket formed by the main needle and the auxiliary needle can limit the depth of the main needle and the auxiliary needle penetrating into the outer sheath, avoiding the main needle and the auxiliary needle piercing the outer sheath during the installation process, causing harm to the installation workers, and ensuring the safety of cable installation.

DETAILED DESCRIPTION

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.

[0020] See also Figure 1-3The utility model provides a technical solution for anti-gnaw underground communication optical cable: it includes an inner sheath 1, a cavity 9 and a main thorn needle 13, the outer sleeve of the inner sheath 1 is provided with a second plastic-coated steel belt 8, the outer sleeve of the second plastic-coated steel belt 8 is provided with a wire mesh 10, a plurality of rubber linings 12 are provided between the wire mesh 10 and the second plastic-coated steel belt 8, a cavity 9 is formed between two adjacent rubber linings 12, a main thorn needle 13 is provided inside the cavity 9, one end of the main thorn needle 13 is fixedly connected to the outer peripheral surface of the second plastic-coated steel belt 8, the top of the main thorn needle 13 does not contact the wire mesh 10, and a plurality of auxiliary thorn needles 14 are provided on the periphery of the main thorn needle 13.

[0021] Specifically, an outer sheath 11 is provided on the outside of the wire mesh 10 , and the outer sheath 11 fixedly covers the outer circumference of the wire mesh 10 .

[0022] Specifically, a first plastic-coated steel strip 2 is provided inside the inner sheath 1 , and the first plastic-coated steel strip 2 is closely attached to the inner wall surface of the inner sheath 1 .

[0023] Specifically, a plurality of sleeves 3 are provided inside the first plastic-coated steel strip 2 , and optical fibers 4 are provided inside the sleeves 3 .

[0024] Specifically, a water-blocking grease 5 is provided between the sleeve 3 and the first plastic-coated steel strip 2 , and the water-blocking grease 5 is filled in the gap between the sleeve 3 and the first plastic-coated steel strip 2 .

[0025] Specifically, a fiber-oil paste 6 is provided between the sleeve 3 and the optical fiber 4 , and the fiber-oil paste 6 fills the gap between the sleeve 3 and the optical fiber 4 .

[0026] Specifically, a reinforcement piece 7 is provided at the inner center of the first plastic-coated steel strip 2 , and the sleeve 3 is arranged around the reinforcement piece 7 .

[0027] In this embodiment, under normal conditions, the main needle 13 is inside the cavity 9 and does not contact the wire mesh 10. A fork is formed between the main needle 13 and the auxiliary needle 14, so that during the installation process, when the outer sheath 11 is squeezed, it collapses into the cavity 9 with the wire mesh 10, and the fork between the wire mesh 10 and the main needle 13 and the auxiliary needle 14 forms a barrier, so that the main needle 13 and the auxiliary needle 14 will penetrate into the inner part of the outer sheath 11, but will not penetrate the outer sheath 11, thereby ensuring the safety during installation and avoiding accidental injury to the installation workers. When the communication optical cable is bitten by mice or reptiles, the surface of the outer sheath 11 is bitten, causing the outer sheath 11 to gradually become thinner, so that after being subjected to the pressure of biting, the main needle 13 and the auxiliary needle 14 penetrate into the inner part of the outer sheath 11 and emerge from the thinned bitten position on the outer sheath 11, thereby causing punctures to the mice or reptiles biting the communication cable, thereby achieving the purpose of protection.
