Abstract
The present invention discloses a kind of cross leading in cable, it is characterised in that:It includes offering four spiral skeleton grooves on skeleton, skeleton, and the cross section of skeleton is that fiber cores are provided with cross, skeleton grooves, and frame center is provided with stiffener, skeleton and is arranged with sheath.The single core number of optical cable of the present invention is 4 ~ 8 cores, can meet big transmission capacity and terraced many family scenes, repeatedly construct the cost brought and time when to save core number not enough, and possesses good lateral pressure resistant performance and tensile properties, resistance to environmental resistance are excellent.
Description
Technical field
The present invention relates to optical cable, and in particular to a kind of cross leading in cable.
Background technology
As domestic " broadband China " building-up work is in full swing by point and face, rural area optical cable to village, fiber entering household
Quickly propel, it is contemplated that to the end of the year, China FTTH ports will be more than 3.5 hundred million, and optical user accounting accelerates to expand, and is up to
75%, optical user quantity surmounts Japan and Korea S, more ranks first in the world.As realizing that FTTH eventually arrives at the transmission medium of user terminal, enter
The house type leading in cable market demand can be in any more always.Become privileged and develop with optical cable application scenarios, enter house type leading in cable
It is required that further harsh.Though conventional butterfly leading in cable possesses good flexibility, flexural property, the features such as constructing convenient, due to
All there is certain limitation in terms of its structure design, dimensional parameters and core number capacity.The conventional single core number of butterfly leading in cable
For 1-2 cores, it is necessary to which repetition circuit is constructed when applied to terraced many family scenes, laid down cost and time are improved, can not also be expired
The big transmission capacity scene application demand of foot.In addition, butterfly structure does not possess good lateral pressure resistant performance and tensile properties, optical fiber holds
It is vulnerable to environmental damage to influence normally to transmit work.In terms of resistance to environmental resistance, conventional butterfly leading in cable performance
It is poor, it is impossible to meet the diversity requirements at intelligent acess family.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of cross leading in cable, the single core of optical cable
Number is 4 ~ 8 cores, can meet big transmission capacity and terraced many family scenes, the cost brought of repeatedly constructing when to save core number not enough and
Time, and possess good lateral pressure resistant performance and tensile properties, resistance to environmental resistance are excellent.
The purpose of the present invention is achieved through the following technical solutions:
A kind of cross leading in cable, it is characterised in that:It includes offering four spiral skeletons on skeleton, the skeleton
Groove, the cross section of skeleton is that fiber cores are provided with cross, the skeleton grooves, and frame center, which is provided with stiffener, skeleton, to be covered
Provided with sheath.
It is preferred that, it is additionally provided with water blocking yarn in the skeleton grooves.
It is preferred that, the waterstop provided with annular between the skeleton and sheath, the waterstop is interference fitted with sheath.
It is preferred that, one or two fiber cores are equipped with each skeleton grooves.
It is preferred that, the screw pitch of the skeleton grooves is 90 ~ 100mm.
It is preferred that, the stiffener is metal, nonmetallic glass fibre or aramid fiber.
It is preferred that, the thickness of the sheath is 4mm.
The beneficial effects of the invention are as follows:Skeleton structure and central strength member, make optical cable possess excellent excellent anti-side
Press performance, tensile properties and resistance to environmental resistance;Flute profile on skeleton can be right-handed screw shape or backpitch shape, both improve optical fiber
1-2 core optical cables can be accommodated in core number capacity, single skeleton grooves, also ensure that certain excess fiber length, rational spiral can be accommodated
Pitch control technique assigns optical cable good tensile property;Skeleton grooves are built into outside water blocking yarn, skeleton and wrap up in waterstop, have optical cable
Standby good block-water performance;Cable jacket materials can select routine PE, low-smoke halogen-free flame-retardant sheath material, nylon according to application scenarios
Protective cover material and chemical protection against rodents repellent protective cover material etc., it is anti-that the selection of diversity sheath material makes optical cable possess excellent resistance to environment
Property, the biological destruction of rodent, ant class can be resisted, at the same it is nontoxic to environment, with the feature of environmental protection.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention;
In figure, 1- skeletons, 2- skeleton grooves, 3- fiber cores, 4- stiffeners, 5- sheaths, 6- water blocking yarns, 7- waterstops.
Embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
Below.
As shown in figure 1, a kind of cross leading in cable, it is characterised in that:It includes offering four on skeleton 1, skeleton 1
Spiral skeleton grooves 2, the screw pitch of skeleton grooves 2 is 90 ~ 100mm, and the cross section of skeleton 1 is cross, each skeleton grooves 2
Inside it is equipped with one or two fiber cores 3;The gap being additionally provided with skeleton grooves 2 in water blocking yarn 6, skeleton grooves 2 passes through water blocking yarn 6
Filling, the center of skeleton 1 is provided with stiffener 4, and stiffener 4 is metal, nonmetallic glass fibre or aramid fiber.Covered on skeleton 1
Provided with sheath 5, the waterstop 7 provided with annular between skeleton 1 and sheath 5, waterstop 7 is interference fitted with sheath 5.
The wherein water suction Pengzhou when meeting water of water blocking yarn 6 forms water blocking layer, prevents water from further flowing, in isolation skeleton grooves 2
Fiber cores 3 and infiltration water, water blocking yarn 6 and waterstop 7 are with the use of allowing optical cable to possess good water resistance.Spiral bone
Rack slot 2 can ensure that fiber cores more than 3 are long, and rational 90 ~ 100mm of pitch assigns optical cable good tensile property.It is preferred that, skeleton
1 answer selection intensity height, flexible, with good thermal processability, see ageing properties and the good material of stability;The thickness of sheath 5 is
4mm。
During production, first multiple fiber cores 3 are respectively placed in four skeleton grooves 2, make fiber cores 3 along spiral skeleton
Groove 2 is wrapped on skeleton 1, then puts block water set and sheath 5, can basis while insert water blocking yarn 6 into the gap of skeleton grooves 2
Application scenarios are chosen routine PE, the material of low-smoke halogen-free flame-retardant sheath 5, the material of nylon sheath wire 5 and chemical material of protection against rodents repellent sheath 5 etc. and made
For sheath 5.
It the above is only the preferred embodiment of the present invention, it should be understood that the present invention is not limited to shape described herein
Formula, is not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and environment, and can be herein
