State the concrete meaning of term in the present invention.
With reference to the accompanying drawing, it elaborates to some embodiments of the present invention.In the absence of conflict, following
Feature in embodiment and embodiment can be combined with each other.
Referring to Fig. 1, Fig. 1 is that all dielectric self-supporting that present pre-ferred embodiments provide enhances the one of rodent-resistant cable 100
Kind sectional view.
As shown in Figure 1, all dielectric self-supporting enhancing rodent-resistant cable 100 includes center reinforcemen 101, optical fiber 103, pine
Casing 102, glass fibre yarn 104, inner sheath 105, non-metallic armoring layer 106 and oversheath 107.
101 surrounding of center reinforcemen is provided with multiple pine sets along the extending direction of the center reinforcemen 101
Pipe 102.Multiple Loose tubes 102 are contacted with the center reinforcemen 101, and multiple Loose tubes 102 abut against it is described
The surrounding of center reinforcemen 101.
It include multifiber 103 in the Loose tube 102,103 quantity of optical fiber for including can be in the Loose tube 102
It is set according to demand, optionally, in the present embodiment, 103 quantity of optical fiber that may include in the every Loose tube 102
It is 6.In the present embodiment, in addition to optical fiber 103 further includes the fiber paste for being filled in the Loose tube 102.
Fiber paste be in current layer-twisted type and central tubular communications optical cable 100 on 103 performance of optical fiber influence maximum material it
One.It is generally acknowledged that fiber paste prevents moisture invasion and two kinds of defencive functions of mechanical damping to optical fiber 103.Fiber paste be by it is a kind of (or
It is several) gelling agent is distributed in base oil, to form a kind of spawn of toughness, in addition to improve its usability
Can, antioxidant and other additives (such as preservative, viscosity modifier, dehydrogenation agent etc.) is also added.Wherein by liquid base oil
It thickens into immobilising gel state substance simultaneously and has thixotropic gelling agent, played during the manufacture and use of fiber paste
Very important effect.Gelling agent is divided into inorganic and organic two class, including fatty acid salt, organobentonite, gas phase dioxy
SiClx, paraffin hydrocarbon and high-molecular copolymer (such as styrene and rubber hydrogenated copolymer).
The glass fibre yarn 104 is wound in side of the Loose tube 102 far from the center reinforcemen 101, so that described
Loose tube 102 tightens together with the center reinforcemen 101 enhances the mechanical strength of cable core.Wherein, glass fibre yarn 104, which has, draws
Intensity height is stretched, is extended small (3%)；Coefficient of elasticity is high, and rigidity is good；Elongation is big in elasticity restriction and tensile strength is high, absorbs punching
Hit the features such as energy is big.Glass fibre yarn 104 can not only play the ability that certain anti-mouse baits in the structure of the present embodiment,
It is also used as a kind of load carrying unit, increases the span of optical cable 100.
The inner sheath 105 is co-axially located at the outside of the glass fibre yarn 104, and the center reinforcemen 101, pine are covered
Pipe 102 and glass fibre yarn 104 are accommodated in the inner sheath 105.It is the cable core of optical cable 100 in the inner sheath 105.In this implementation
In example, the inner sheath 105 is fabricated using polythene material.
The oversheath 107 is co-axially located at the outside of the inner sheath 105, and the setting of non-metallic armoring layer 106 exists
Between the oversheath 107 and the inner sheath 105.In the present embodiment, the setting of non-metallic armoring layer 106 is described outer
Between sheath 107 and the inner sheath 105.The non-metallic armoring layer 106 includes multiple prolonging along the center reinforcemen 101
Stretch the flat protection against rodents non-metallic member 1061 that direction is wrapped in 105 outside of inner sheath, wherein adjacent flat shape protection against rodents is non-
Gap between metal component 1061 is less than a default spacing, to prevent mouse from passing through adjacent flat shape protection against rodents non-metallic member
Bait the internal structure of optical cable 100 in gap between 1061.By being set between the oversheath 107 and the inner sheath 105
Setting non-metallic armoring layer 106 can be thus achieved physics protection against rodents.The flat protection against rodents non-metallic member 1061 manufactured using FRP and
At.
FRP, fibre-reinforced plastics are the abbreviations of English (Fiber Reinforced Plastics), existing
CFRP, GFRP, AFRP, BFRP etc..GFRP is called glass reinforced plastic in Chinese.FRP composite material is by fibrous material and basis material
The high-performance profile material formed after mixing according to a certain percentage.Wherein GFRP is different according to used resin variety, there is polyester
The types such as glass reinforced plastic, fiber glass epoxy, phenolic fiberglass reinforced plastics.General FRP has light and hard, non-conductive, high mechanical strength, recycling
Utilize few, the characteristics such as corrosion-resistant.
In the present embodiment, the center reinforcemen 101 can also using the FRP addition pungent cellulosic material manufacture and
At.
Referring to figure 2., in the present embodiment, 103 quantity of optical fiber needed for the optical cable 100 according to different requirements,
May be different, i.e., the quantity of Loose tube 102 also can be different.When the small number of Loose tube 102, it cannot be guaranteed that the Loose tube
102 when abutting against the surrounding of the center reinforcemen 101 and causing the cable core structure of optical cable 100 unstable.The optical cable 100 is also
It may include gasket for packing 108, the gasket for packing 108 is arranged along the extending direction of the center reinforcemen 101 to be added at the center
The surrounding of strong part 101, the gasket for packing 108 cooperates with Loose tube 102 abuts against the surrounding of the center reinforcemen 101,
To stablize the internal structure of the optical cable 100, wherein the diameter phase of the diameter of the gasket for packing 108 and the Loose tube 102
Together.
Referring to figure 3., in the present embodiment, the optical cable 100 can also include: water blocking yarn 109, the water blocking yarn 109
Along the center reinforcemen 101 extending direction and be set to the center reinforcemen 101 and Loose tube 102 or gasket for packing 108
Between gap in.Water blocking yarn 109, which has, prevents steam along 100 longtitudinal dispersion of optical cable, protects the work of 103 service life of optical fiber
With.
Optionally, referring once again to Fig. 3, in the present embodiment, the optical cable 100 can also include: waterstop 110, institute
It states waterstop 110 and is wrapped in the side of the Loose tube 102 and the gasket for packing 108 far from the center reinforcemen 101, it is described
Waterstop 110 is located at the inside of the glass fibre yarn 104.The waterstop 110 is set to the glass by way of pricking yarn and tying up
The inside of fine yarn 104.
In the present embodiment, by the way that water blocking yarn 109 and waterstop 110 are arranged in optical cable 100, because of water blocking yarn 109 and resistance
Some polymer in water band 110 contain a large amount of hydrophilic radical, such as carboxylic acid group, carboxylic acid group's salt, hydroxyl, ether etc., when
When water blocking yarn 109 or waterstop 110 touch water, by these hydrophilic radicals, cross-linked polymer opens rapidly, forms net
Shape.Moisture content is housed in these nets, and water blocking yarn 109 or 110 volume of waterstop sharply expand, form gel, fill up in optical cable 100
