Abstract
The utility model relates to an all-medium chemical rodent-resistant optical cable used for preventing from being bitten by a rat, comprising a cable core, an inner sheath wrapping the cable core, and an outer sheath wrapping the inner sheath. The all-medium chemical rodent-resistant optical cable is characterized in that the outer sheath is formed by compositing a rat-proof chemical layer and an outer protecting layer internally and externally, and the rat-proof chemical layer is formed by mixing a rodent repellant agent and a sheath material. The outer protecting layer of the utility model does not contain the rodent repellant agent, and rodent repellant agent capsaicin is uniformly distributed in the rat-proof chemical layer contacted with the outer protecting layer tightly according to a certain proportion. Because the cabling processing of the outer protecting layer and the rat-proof chemical layer is formed via co extrusion composite, the volatilization of the rodent repellant agent capsaicin is prevented effectively, thereby effectively reducing and preventing the environment pollution and the harms to people, and achieving the effective rat-proof effect via the set rat-proof chemical layer; and by arranging a glass fiber yarn or a glass fiber belt, the optical cable rat-proof capability is enhanced further from the physical level. The all-medium chemical rodent-resistant optical cable is simple in structure, low in manufacturing cost, flexible in optical cable, light in weight, and easy in laying.
Description
Technical field
The utility model relates to a kind of full medium chemistry rodent-resistant cable that protection against rodents bites that is used for, and this optical cable is applicable to that mouse suffers from heavier area and lays.
Background technology
Fiber cable laying is suffered from heavier area mouse, is bitten and destroyed situation by mouse through regular meeting at present.At present the mode that bites of optical cable protection against rodents is divided into two types of physics protection against rodents and chemical protections against rodents.The physics protection against rodents mostly is that coated steel band or steel wire are set in oversheath, and not only material and cost of manufacture are expensive, optical cables heavy, and also cable is more stiff, lays and safeguards inconvenience.The chemistry protection against rodents is meant that in the oversheath of optical cable, adding expelling mouse agent by a certain percentage reaches the purpose that protection against rodents bites.Chemistry protection against rodents mode cable configuration is simple, cost of manufacture is low and be easy to lay.Existing chemical rodent-resistant cable is the oversheath that directly expelling mouse agent is become optical cable with the protective cover material hybrid process, and this compound heats in process of production and can volatilize a large amount of irritative gas when extruding, and not only contaminated environment also is detrimental to health.
Summary of the invention
The utility model technical matters to be solved is the deficiency that exists to above-mentioned prior art and proposes a kind of full medium chemistry rodent-resistant cable; It is not only simple in structure; Cost of manufacture is low, and when making, can effectively reduce and prevent the pollution of environment and the harm of human body.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include cable core and the inner sheath that coats cable core, outside inner sheath, coat oversheath, it is characterized in that described oversheath is by being composited inside and outside protection against rodents chemosphere and the outer jacket.
Press such scheme, described protection against rodents chemosphere is mixed by expelling mouse agent and protective cover material.
Press such scheme, described expelling mouse agent is that pungent is plain.
Press such scheme, described protection against rodents chemosphere and outer jacket coextru-lamination form.
Press such scheme, between inner sheath and oversheath, be laid with glass fiber yarn or glass fiber tape.
Press such scheme, the monolateral radial thickness of described outer jacket is 0.1mm ~ 0.5mm.
Press such scheme, described cable core is layer-twisted type cable core, central beam tube type cable core or skeleton cable core.
The beneficial effect of the utility model is: 1, the outermost outer jacket of optical cable does not contain expelling mouse agent; With to be uniform-distribution with the expelling mouse agent pungent in the protection against rodents chemosphere that outer jacket closely contacts by a certain percentage plain; Because outer jacket and the processing of protection against rodents chemosphere form through coextru-lamination; Kept out the plain volatilization of expelling mouse agent pungent in the processing effectively, thereby effectively reduced and prevent, and can reach effective protection against rodents effect through set protection against rodents chemosphere to the pollution of environment and the harm of human body; 2, glass fiber yarn or glass fiber tape are set, have further strengthened optical cable protection against rodents ability from physical layer; 3, simple in structure, cost of manufacture is low, and optical cable is soft, and is in light weight, is easy to lay.
Description of drawings
The radial structure sectional view of first embodiment of Fig. 1 the utility model.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Include cable core 1 and the inner sheath 2 that coats cable core; Described cable core is the layer-twisted type cable core, outside inner sheath, coats oversheath, and described oversheath is by being composited inside and outside protection against rodents chemosphere 4 and the outer jacket 5; Described protection against rodents chemosphere is mixed by expelling mouse agent and protective cover material; Expelling mouse agent is that pungent is plain, and outer jacket is not for containing the outer jacket that conventional protective cover material constituted of expelling mouse agent, and the monolateral radial thickness of outer jacket is 0.3mm.Described protection against rodents chemosphere and outer jacket stranding add the coextru-lamination in man-hour and form.Can keep out the plain volatilization of expelling mouse agent pungent effectively through the coating of outer jacket.Be laid with glass fiber yarn 3 between this external inner sheath and the oversheath, the monolateral thickness that glass fiber yarn coats is 0.3mm ~ 0.6mm, has further strengthened the protection against rodents ability and the service time of optical cable from physical layer.
Claims (5)
1. a full medium chemistry rodent-resistant cable includes cable core and the inner sheath that coats cable core, outside inner sheath, coats oversheath, it is characterized in that described oversheath is by being composited inside and outside protection against rodents chemosphere and the outer jacket.
2. by the described full medium chemistry rodent-resistant cable of claim 1, it is characterized in that described protection against rodents chemosphere and outer jacket coextru-lamination form.
