Abstract
The utility model relates to a parallel ribbon cable, the structure of ribbon cable is as follows: the ribbon cable is formed by wrapping an optical fiber ribbon 1, aramid fiber 2 and an outer sheath 3 layer by layer from inside to outside; the optical fiber ribbon is composed of 8 bare fibers in parallel: the diameter of the bare fiber is 250 micrometers, and the bare fiber can also be a colored fiber with the diameter of 250 mm; the aramid yarn is placed in a flat support manner, and has good tensile capacity; the outer sheath material is made of a thermal shrinkage low-smoke halogen-free polyolefin material, and is formed by extrusion molding through an extruding machine, so that the material has high compression resistance and bending resistance; the optical cable structure is miniaturized, light, flexible and easy to bend, can be made into a tape measure-contained contractible optical cable and is convenient to place; the optical cable is easy to open and convenient to construct.
Description
Technical field
A kind of band cable parallel is the utility model is related to, belongs to optical cable field.
Background technology
In use, anti-collapse power is insufficient for conventional parallel band cable, and external diameter is greatly, again.
The content of the invention
The technical problem that the utility model need to solve be overcome the shortcomings of it is above-mentioned, there is provided it is a kind of can resistance to compression, stability is strong
Parallel band cable.
According to the above-mentioned technical problem that need to be solved, the utility model provides a kind of band cable parallel, and it includes two phases arranged side by side
Even but the delivery unit of UNICOM, the delivery unit do not include fibre ribbon, wrap up aramid layers and the cladding institute of the fibre ribbon
State the external sheath layer of aramid layers；Two adjacent medial extremitys of delivery unit are connected together, and are also set in described two delivery units
There is admittedly strong part, the solid strong part is close to delivery unit outboard end.
Further improved as the utility model, center pair of the solid strong part with respect to the junction of two delivery units
Claim.
Further improved as the utility model, longitudinal interface of the solid strong part is circle.
Further improved as the utility model, the fibre ribbon is by 4 or 8 or 16 naked fibres side by side or fine group of coloring
Into the bare fibre or fine a diameter of 250 microns of coloring.
The utility model is provided with solid strong part in the outboard end with cable parallel, can improve its compressive property, in use,
Good anti-collapse power can be born.Moreover, the utility model miniaturized structure with cable parallel, light, it is easy to construct.
Brief description of the drawings
Be more fully described exemplary embodiment of the present utility model by referring to accompanying drawing, it is of the present utility model more than and its
Its aspect and advantage will become more easily clear, in the accompanying drawings：
Fig. 1 is the utility model longitudinal profile structure schematic with cable parallel.
Embodiment
Hereinafter, the utility model is more fully described now with reference to accompanying drawing, various implementations is shown in the drawings
Example.However, the utility model can be implemented in many different forms, and it should not be construed as limited to reality set forth herein
Apply example.On the contrary, it will be thorough and complete to these embodiments are provided so that the utility model discloses, and by model of the present utility model
Enclose and be fully conveyed to those skilled in the art.
Hereinafter, exemplary embodiment of the present utility model is more fully described with reference to the accompanying drawings.
As shown in figure 1, originally new include two delivery units 1 arranged side by side, two phases of delivery unit 1 arranged side by side with cable parallel
Even but not connecting, two delivery units 1 are in pancake, and its adjacent medial extremity 10 is connected together, on the whole, parallel band cable
In pancake.
Two delivery units 1 include fibre ribbon 2, aramid layers 3 and external sheath layer 4 from inside to outside.The fibre ribbon 2 is by simultaneously
8 naked fibres composition of row, the bare-fiber diameter are 250 microns.Thus, miniaturized structure of the present utility model is lighter,
It is easy to construct.In the utility model other embodiment, the quantity of naked fibre can be 4 or 16 or other numbers in fibre ribbon
Amount, naked fibre also can use coloring is fine to replace.
The aramid layers 3 wrap up fibre ribbon 2, and aramid layers 3 have good tensile capacity.
The oversheath 4 coats the aramid layers 3, and the material of oversheath 4 uses the low halogen-free polyolefin material of hot shortness, squeezes
Molding machine extrusion forming, material have the characteristics of high resistance to compression, bend resistance.
It is additionally provided with admittedly strong part 4 in two delivery units 1 with cable parallel in the utility model, Gu strong part 4 is single close to transmission
The outboard end 11 of member 1, i.e., solid strong part are arranged at two outboard ends with cable parallel, so can both improve the anti-collapse with cable parallel
Power performance.
The solid strong part 4 is located at the outboard end of two delivery units, in the junction 12 of its relative two delivery unit
The heart is symmetrical, and the distance apart from the central point of junction 12 is equal, and so making the utility model, the compressive resistance with cable is uniform parallel, stable
By force.Gu longitudinal interface of strong part is circle, solid strong part can be light and hard, non-conductive, high mechanical strength in the present embodiment
Material be made, such as：Organic toughened glass or fiber glass epoxy or phenol aldehyde glass Steel material.
The utility model is provided with solid strong part in the outboard end with cable parallel, can improve its compressive property, in use,
Good anti-collapse power can be born.Moreover, the utility model miniaturized structure with cable parallel, light, it is easy to construct.
Embodiment of the present utility model is the foregoing is only, is not limited to the utility model.The utility model
Can there are various suitable changes and change.All made within spirit of the present utility model and principle are any to be changed, is equivalent
Replace, improve etc., it should be included within the scope of protection of the utility model.
