Embodiment 1

[0025] Embodiment one, combining Figure 1-Figure 4 Be explained:

[0026] A layer-twisted anti-rat-biting optical cable, comprising: a protective jacket 1, a yarn binding layer 4, a cable core filling glue 5, an optical fiber 6 and a reinforcing steel wire 7, the protective jacket 1 is coaxially provided with a yarn binding layer 4, and the yarn binding layer 4 The yarn layer 4 is filled with a cable core filling glue 5, and a plurality of optical fibers 6 are arranged in the cable core filling glue 5, and a reinforcing steel wire 7 is coaxially arranged in the protective jacket 1, and the reinforcing steel wire 7 is located in the cable core filling glue 5. A composite steel belt 3 is arranged between the binding yarn layer 4 and the protective jacket 1, a rat-repelling layer 2 is arranged inside the protective jacket 1, an optical fiber 6 is arranged around a reinforcing steel wire 7, the protective jacket 1 is made of rubber, and an anti Rat masterbatch, reinforced steel ...

Embodiment 2

[0027] Embodiment two, combining Figure 1-Figure 4 Be explained:

[0028] The optical fiber 6 includes: a loose tube 6-1, a fiber inner filler 6-2 and an optical fiber body 6-3, the loose tube 6-1 is located in the cable core filler 5, and the loose tube 6-1 is Filled with the fiber filling glue 6-2, the fiber body 6-3 is located in the fiber filling glue 6-2.

Embodiment 3

[0029] Embodiment three, combining Figure 1-Figure 4 Be explained:

[0030] The rodent repelling layer 2 includes wrapped iron net A2-1, filled camphor 2-2, wrapped iron net B2-3, wrapped iron net A2-1 and wrapped iron net B2-3 are coaxially arranged on the protective jacket 1, so A cavity is formed between the wrapped iron net A2-1 and the wrapped iron net B2-3, and the filled camphor 2-2 is arranged in the cavity. The wrapped iron net A2-1 leaked, and the filling of camphor 2-2 can release the unpleasant smell of mice, and play the function of dispersing the rats, while the wrapped iron net A2-1 and wrapped iron net B2-3 have the characteristics of being relatively hard. After camphor 2-2 loses its effect, it plays the role of bite resistance.

[0031] Working principle of the present invention:

[0032] Because the anti-rat masterbatch is added in the protective coat 1, it can play a role in dispersing the rats. When the anti-rat masterbatch loses its effectiveness and ...

Abstract

The invention belongs to the field of rat-bite-proof optical cables, and particularly relates to a layer-stranded rat-bite-proof optical cable which comprises a protective jacket, a yarn binding layer, cable core filling glue, optical fibers and reinforcing steel wires, the yarn binding layer is coaxially arranged in the protective jacket, the cable core filling glue is loaded in the yarn binding layer, the optical fibers are arranged in the cable core filling glue, a reinforcing steel wire is coaxially arranged in the protective jacket, the reinforcing steel wire is located in the cable core filling glue, and a composite steel belt is arranged between the yarn binding layer and the protective jacket. The device can adopt multi-layer rat repelling, the rat repelling effect is better, and the device can prevent the optical fiber from being squeezed and crushed.

Description

technical field [0001] The invention belongs to the field of anti-rat-biting optical cables, and in particular relates to a layer-twisted anti-rat-biting optical cable. Background technique [0002] The existing layer-twisted communication optical cable has poor rodent-proof performance. For reasons of protecting the ecological balance and the growth of economic crops, measures such as poisoning and hunting should not be taken to prevent rodents, so the products often have communication optical fibers in areas with severe rodent damage. In the case of being bitten by mice, communication signal transmission failure occurs, causing serious economic losses. The structure of the existing layer-stranded optical cable is: the center of the optical cable is a strengthening member, which is formed by twisting a plurality of loose tubes containing optical fibers, and a layer of steel-plastic composite tape is longitudinally wrapped on its outer diameter. The outside of the composite...
