Description
Technical field
It the utility model is related to the cable applied to the communications field, more particularly to a kind of fiber optic cables.
Background technology
Fiber optic cables (being also optical fiber cable) are a kind of communication cables, by two or more glass or plastic light fibre core structure
Into in the prior art, then this glass or plastic light fibre core is wrapped, ring by ring steel belt again often by PVC sleeve covers
Shape steel band outer layer then has polyethylene outer sheath wrapping；But found in the experience used for many years via our company, in the prior art
Fiber optic cables cut, install, easily making to produce axle between polyethylene outer sheath and ring steel belt during bracing wire etc.
To skew, and fiber cores are extremely fragile sensitive components, connect up external force in occasion, use environment (such as humidity, temperature
Degree etc.) influence to its performance is particularly great, especially, as long as the local location of fiber optic cables loses polyethylene outer sheath
Protection, be likely to have influence on the performances of fiber cores, therefore, how effectively to avoid polyethylene outer sheath and ring steel belt it
Between produce axial dipole field turn into our company research and development Main way.
The content of the invention
A kind of the defects of the purpose of this utility model is to overcome prior art, there is provided simple in construction, novel in design, performance
Reliable fiber optic cables.
To achieve the above object, the utility model uses a kind of fiber optic cables, including polyethylene outer sheath, ring steel belt and
Some fiber cores and sleeve pipe, described sleeve pipe surround outside the fiber core, and for more effectively prevent moisture and
The erosion of moisture, greasy for preventing water is filled between described sleeve pipe and fiber core；The fiber core for being surrounded with sleeve pipe with
Put centered on the axle center of ring steel belt and be circumferentially evenly distributed in ring steel belt, be further likewise, in the utility model
Ensure the sealing of fiber optic cables, the infiltration of moisture and moisture is prevented, in the ring steel belt and the light for being surrounded with sleeve pipe
Gap between fine inner core is filled with optical fiber ointment；At least there is one around the annular on the outer peripheral face of the ring steel belt
Helically the axially extending projection of formula, the polyethylene outer sheath surround the steel band outer layer to steel band outer peripheral face.
Pass through the above-mentioned improvement to prior art, it is clear that, due to being provided with edge on the outer peripheral face of ring steel belt
The side face helically axially extending projection of formula, when polyethylene outer sheath surrounds on the ring steel belt, equivalent to described
The embedded polyethylene outer sheath of projection inner peripheral surface, it is therefore apparent that to raised on ring steel belt in the utility model
Set, effectively prevent the problem of axial dipole field is produced between polyethylene outer sheath and ring steel belt, and then make it that this practicality is new
The use reliability of fiber optic cables in type is higher, and performance is more stable.
Further set as of the present utility model, the shaft core position of the ring steel belt is provided with center reinforcemen, institute
The fiber core for being surrounded with sleeve pipe is stated around the center reinforcemen array distribution.Those skilled in the art passes through above-mentioned technology
Scheme understands that the setting of reinforcer can effectively improve impact resistance, Resisting fractre ability and the pliability of fiber optic cables.
Further set as of the present utility model, there is some array distribution on the outer peripheral face of the polyethylene outer sheath
Individual is substantially in the lip of circumferentially extending, is formed between the lip and the outer peripheral face of the polyethylene outer sheath 1 and suppresses spacing.This
Utility model is arranged such on the outer peripheral face of polyethylene outer sheath, makes it when in use, is especially needing aerial cable
When, due between lip and the outer peripheral face of polyethylene outer sheath there is suppressing spacing, when fiber optic cables and cable clamp are carried out
During cooperation, lip is by the circumferential clamping force of cable clamp, while lip is by with certain elasticity, therefore, the utility model
Fiber optic cables when coordinating cable clamp, may be such that its cooperation is compacter, installation it is relatively reliable.
Brief description of the drawings
Fig. 1 is the front view of fiber optic cables in the utility model.
Fig. 2 is the schematic perspective view that fiber optic cables remove after polyethylene outer sheath in the utility model.
Embodiment
As depicted in figs. 1 and 2, the present embodiment uses a kind of fiber optic cables, including polyethylene outer sheath 1, the and of ring steel belt 2
Six fiber cores 3 and sleeve pipe 4, described sleeve pipe 4 surround outside the fiber core 3, are more effective in the present embodiment
The erosion of moisture and moisture is prevented, greasy for preventing water 5 is filled between described sleeve pipe 4 and fiber core 3；It is described to be surrounded with sleeve pipe
4 fiber core 3 is put centered on the axle center of ring steel belt 2 and is circumferentially evenly distributed in ring steel belt 2, likewise, in this reality
Apply in example, to be further ensured that the sealing of fiber optic cables, prevent the infiltration of moisture and moisture, in the ring steel belt 2 and institute
State the gap being surrounded between the fiber core 3 of sleeve pipe 4 and be filled with optical fiber ointment 6；Knowable to Fig. 1 combinations Fig. 2, the ring steel belt
At least there is one around the outer peripheral face of ring steel belt 2 helically axially extending projection 20 of formula on 2 outer peripheral face, it is described to gather
Ethene oversheath 1 surrounds the outer layer of ring steel belt 2.
Further shown in Fig. 1, in the present embodiment, for effectively improve the impact resistance of fiber optic cables, Resisting fractre ability and
