Description
Technical field
The utility model relates to optical cable technology field more particularly to a kind of optical cables with impact resistance.
Background technique
Optical fiber, abbreviation optical fiber is a kind of up to the total reflection principle biography for causing light in the fiber made of glass or plastics
Defeated light conducts tool.Optical cable is a certain number of optical fiber according to the certain way group stranding heart, is surrounded by sheath, some also claddings outside
Outer jacket, to realize a kind of communication line of optical signal transmission.Existing optical cable impact resistance is poor, by impact force
When, it is be easy to cause the breakage of optical cable, causes optical signal that cannot be propagated in optical cable, affects the conveying of information.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed has shock resistance
The optical cable of ability.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of optical cable with impact resistance, including protective layer are designed, more is equipped in the protective layer and leads core, it is described
It leads core outer surface and is enclosed with outer layer, the protective layer outer surface is pasted with enhancement layer, and the enhancement layer outer surface is pasted with buffering
Layer, the buffer layer outer surface are pasted with anti-impact force layer, and anti-impact force layer outer surface is pasted with anti-aging layer.
Preferably, the protective layer includes layer of PVC, and the layer of PVC outer surface is pasted with flame-retardant layer, the flame-retardant layer appearance
Face is pasted with supporting layer.
Preferably, filled layer is filled in the protective layer.
Preferably, the protective layer internal diameter accounts for 2/5ths of optic cable diameter.
The utility model proposes a kind of optical cable with impact resistance, beneficial effect is: anti-impact force layer and slow
The design for rushing layer, convenient for carrying out snubber to impact force, prevents optical cable by impact force when optical cable is by impact force
When, it damages, causes optical cable that cannot normally work, the design of enhancement layer enhances the intensity of optical cable, prevents optical cable stress
Deformation occurs, causes to squeeze to the inner core of optical cable, and causes the breakage of optical cable, and the design of protective layer plays the effect of waterproof, together
When play the effect of fire-retardant fireproof again, anti-aging layer enhances the ageing resistance of optical cable, prevents optical cable to be oxidized and cause breakage.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of optical cable with impact resistance structural schematic diagram.
Fig. 2 is the structural schematic diagram of protective layer.
In figure: anti-aging layer 1, buffer layer 3, enhancement layer 4, filled layer 5, leads core 6, protective layer 7, PVC at anti-impact force layer 2

Polycarbonate is made, and has the characteristics that high-intensitive and coefficient of elasticity, high impact play support when by impact force
Effect can prevent optical cable by deformation, cause the damage of optical cable, and 4 outer surface of enhancement layer is pasted with buffer layer 3, buffer layer 3 by
Butadiene rubber, has the characteristics that elasticity is high, carries out snubber to impact force, is conducive to reduction impact force and causes to cable interior
It influences, 3 outer surface of buffer layer is pasted with anti-impact force layer 2, and anti-impact force layer 2 is made of ABS resin, has good shock resistance
Property, snubber is carried out to impact force, prevents impact force from causing the breakage of optical cable, is conducive to extend the service life of optical cable, is resisted
2 outer surface of impact force layer is pasted with anti-aging layer 1, and anti-aging layer 1 is made of nitrile rubber, has good ageing-resistant ability,
Also have with preferable wear resistance simultaneously, enhances the anti-aging ability of optical cable, and wearability.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
