Background technique
Optical cable is often erected at damaged by rats area, woods birds dense region etc., and usually the optical cable in such area is applying
If a period of time, can be caused optical cable to damage by damaged by rats, the calamity of unfirmly closing after.Currently, anti-bite under normal conditions use two kinds of sides
Formula: chemical method and physical method；Chemical method is usually that repellant is added in jacket material, makes muroid and birds in this approach not
The oversheath for liking destroying optical cable, to protect optical cable damage；Or oversheath is designed to the face that birds do not like
Color etc., but these method effects are limited, are also easy to pollute production and use environment, and pungent element taste as time goes by
Road, which can weaken, even to disappear, and warning color meeting weather stain makes protection effect worse and worse；Physical method is usually in oversheath
Interior increase coat of metal such as steel wire spiral armor or stainless steel band armouring etc., to protect cable outer sheath hard enough,
It is not easy to be destroyed, this method is more reliably to prevent nibbling method at present, but use steel wire armor layer or stainless steel band
The coat of metal such as armouring not only make the bending property of optical cable be deteriorated, but also considerably increase the weight and outer diameter of optical cable, also increase
The production of optical cable, construction has been added to lay and use difficulty.And weight is big, cost is high is also not suitable for aerial laying, is less suitable for
Lightning stroke prone areas, and single means of defence is undesirable.

The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Embodiment 1
As shown in Figure 1, present embodiment discloses a kind of anti-bite self-support cable of all dielectric, including cable core 1, outside the cable core
Close-packed arrays spiral winding has fiberglass reinforced plastics band 2, and the fiberglass reinforced plastics band 2 is platypelloid type, platypelloid type
Fiberglass reinforced plastics band be easier to be coated on the outside of cable core relative to circular fiberglass reinforced plastics band, Er Qiebian
The conductor assembly outer diameter of flat-shaped cladding is less than the conductor assembly outer diameter of round bar cladding, reduces the outer diameter of entire optical cable；The glass fibre increases
Strong plastic tape 2 is arranged closely in 1 outside of cable core, and intermediate there are gaps, also plays protective effect to cable core 1 in this way；It is described
Fiberglass reinforced plastics band 2 is spirally wound on 1 outside of cable core by way of twisted, will not influence the bending of entire cable in this way
Performance.Restrictive coating 3 is set outside the fiberglass reinforced plastics band 2, the restrictive coating includes inner sheath 31 and oversheath 32, institute
31 edge of inner sheath setting wavy bulge, the outer coating pungent element of protrusion are stated, the pungent is known as irritation taste, in this way
When mouse or birds can be abandoned stinging pecking when pecking and biting the pungent element on the outside of protrusion, inner sheath 31 will not be injured, and such peppery
Monosodium glutamate does not influence environment；The oversheath 32 is nylon material, one layer of oversheath 32 is provided on the outside of inner sheath 31, both
It can prevent the pungent element in inner sheath 31 from quickly volatilizing at any time, while nylon material material itself is harder, is also not easy to sting
It is broken, the messenger wire 5 of the connection of suspender belt 4 is provided on the outside of the restrictive coating 3, the restrictive coating 3, suspender belt 4, messenger wire 5 are wholely set, can
Biggish weight is born, is provided with fiberglass reinforced plastics round bar 51 in the messenger wire 5.
Optical cable entire in this way is formed triple anti-bite systems in conjunction with chemical method and physical method from inside to outside, and first
Protect again: nylon sheath wire, material itself is hard be not easy to sting it is bad；Second protects again: pungent, which is known as irritation taste, can drive mouse
Class or birds；Third is protected again: fiberglass reinforced plastics band contains glass fibre, and glass fibre can hurt when unfirmly closing, damaged by rats
The oral cavity of evil animal, makes animal abandon destroying.
