Abstract
The utility model is related to a kind of coarse pitch slotted core cables, include skeleton cable core and oversheath, skeleton cable core includes skeleton and is disposed on the opening skeleton grooves of skeleton periphery, fibre ribbon is installed in skeleton grooves, it is characterized in that the skeleton grooves are circumferentially rotatable, helically flute profile, screw pitch are 650~1500mm.The utility model under same skeleton pay off rack rotary speed, is conducive to improve speed of production and efficiency using coarse pitch skeleton grooves；Torsion pitch of the fibre ribbon in coarse pitch skeleton grooves is also increased, and is conducive to improve stress of its stacked-layer fiber optic with matrix side fibre, reduces the control difficulty that fibre ribbons enter slot technique, also saves the fibre ribbon of unit cable length；Coarse pitch skeleton makes it possible 12~24 core optic fibre belt optics for slotted core cable, the fine capacity of optical cable is added, so as to reduce optical cable cost.
Description
Technical field
The utility model is related to a kind of coarse pitch slotted core cables, belong to optic communication transmission technique field.
Background technology
Slotted core cable due to high density, convenient for difference and without ointment the characteristics of become access net optical cable construction and match somebody with somebody line segment
Important selection.The cable core of slotted core cable includes skeleton and is disposed on the opening skeleton grooves of skeleton periphery, in skeleton
It feels at ease equipped with steel wire or non-metal reinforcement member, fibre ribbon is put into skeleton grooves, wrapped one layer of waterstop outside cable core, outermost cladding
Oversheath.Skeleton grooves on skeleton are mostly tangled structure using spiral, i.e. skeleton grooves are circumferentially rotatable with certain pitch, existing
Skeleton slot pitch maximum is usually no more than 500mm, carries out while to front haulage skeleton in stranding plus man-hour requirement continuous
Rotation, enters skeleton grooves convenient for fibre ribbon in a manner of Straight alignment.Since production equipment especially skeleton folding and unfolding coil holder is huge stupid
Weight, the rotary speed of skeleton are restricted, and the production efficiency of optical cable, while fibre ribbon will be influenced when skeleton slot pitch is smaller
Smaller pitch can also influence the stress of fibre ribbon matrix side fibre when entering slot.
The content of the invention
The technical problem to be solved by the utility model is to provide a kind of in view of the deficiency of the prior art
Coarse pitch slotted core cable, the optical cable can improve production efficiency, reduce cost, and improve matrix side fibre when optical fiber brings slot into
Force-bearing situation.
The utility model is to solve the problems, such as that used technical solution set forth above is：Include skeleton cable core and outer
Sheath, skeleton cable core include skeleton and are disposed on the opening skeleton grooves of skeleton periphery, and optical fiber is installed in skeleton grooves
Band, it is characterised in that the skeleton grooves are circumferentially rotatable, helically flute profile, and screw pitch is 650~1500mm.
By said program, the screw pitch is 650~1000mm.
By said program, the skeleton grooves radial section is rectangle.
By said program, the skeleton grooves are circumferentially evenly distributed with 3~12, and the rotation direction of each item is identical with pitch.
By said program, the skeleton grooves rotation direction in S to or Z-direction or SZ to.
Radially stack 2~8 fibre ribbons by said program, in the skeleton grooves, the core number of every fibre ribbon for 2~
24 cores.
By said program, in skeleton cable core outer cladding water blocking layer and armor, armor outer cladding oversheath.
The beneficial effects of the utility model are：1st, using coarse pitch skeleton grooves in same skeleton pay off rack rotary speed
Under, be conducive to improve speed of production and efficiency；2nd, torsion pitch of the fibre ribbon in coarse pitch skeleton grooves is also increased, favorably
In improving stress of its stacked-layer fiber optic with matrix side fibre, the control difficulty that fibre ribbons enter slot technique is reduced, also saves unit
The fibre ribbon of cable length；3rd, coarse pitch skeleton so that 12~24 core optic fibre belt optics for slotted core cable, add
The fine capacity of optical cable, so as to reduce optical cable cost.
Description of the drawings
Fig. 1 is the axial schematic diagram of the utility model skeleton grooves.
Fig. 2 is the radial cutaway view of the utility model one embodiment.
Specific embodiment
The embodiment of the utility model is further illustrated below in conjunction with the accompanying drawings.
Include skeleton cable core and oversheath 6, skeleton cable core includes skeleton 1 and is disposed on skeleton periphery
Be open skeleton grooves, and frame center is installed on steel wire or non-metal reinforcement member 5, and the skeleton grooves radial section is rectangle, circumferential
6 uniformly distributed, skeleton grooves are circumferentially rotatable, helically flute profile, screw pitch 700mm, and skeleton grooves rotation direction is in Z-direction, skeleton grooves
Helixangleβ is about 2~3 °, and the pitch angle alpha for the skeleton grooves that existing pitch is below 500mm is typically larger than 3 °.The present embodiment
In each skeleton grooves rotation direction it is identical with pitch, fibre ribbon 2 is installed in skeleton grooves, fibre ribbon radially stacks 6 fibre ribbons,
The core number of every fibre ribbon is 6 cores.In skeleton cable core outer cladding water blocking layer 3 and armor 4, armor outer cladding oversheath 6.
