Utility model content
Problem to be solved in the utility model overcomes above-mentioned prior art Problems existing, and a kind of light ship optical cable is provided, under the prerequisite that combination property in machinery, environment etc. does not reduce compared with the Optical Cables for Shipboard of existing routine, effectively reduce the outside dimension of optical cable and reduce the weight of optical cable.
For solving the problems of the technologies described above, technical solution of the present utility model is achieved in that a kind of light ship optical cable, described optical cable comprises fiber unit, enhancement Layer and oversheath, and described fiber unit is combined by least one optical fiber and the nylon inner sheath that is coated on outer fiber; Described fiber unit outside is uniformly coated with enhancement Layer, and is coated with polymkeric substance oversheath at enhancement Layer, and described oversheath outer braid has by tinsel as cable armor layer.
Further, described fiber unit external diameter is between 1.0mm ~ 1.5mm.
Further, between described optical fiber is one to four.
Further, described optical fiber is carbon coated optical fiber.
Further, put together by stranded between described optical fiber.
Further, between described optical fiber, straight parallel is put together.
Further, described optical fiber is the one in bare fibre, coated fiber or tightly packaged fiber.
Further, described cable armor layer is the one in stainless steel wire or tinned copper wire.
Further, described optical cable entire outer diameter is not more than 5.5mm.
The utility model can bring following beneficial effect: first, and optical cable of the present utility model effectively can reduce size, the about 50kg/km of weight, effective reduction weight, use this optical cable to not only reduce transport, cable laying operation difficulty, and effectively can reduce cost of products, increase economic efficiency.
Secondly, the utility model Optical Cables for Shipboard, owing to have employed carbon coating tightly packaged fiber, effectively can resist the moisture in portion belowdecks, compare with other optical fiber of existing market, carbon coated optical fiber has higher endurance index, and the serviceable life of optical fiber is higher, improves the serviceable life of optical cable further.
Again; the utility model Optical Cables for Shipboard; owing to have employed metal knitted silk as cable armor layer; there is softness, advantage that bending radius is little; what can adapt to little bending diameter in cabin lays occasion; and optical fiber can be protected from the impact of external mechanical stress, there is splendid resistance to compression, shock resistance, effectively can resist the destruction of the rodent in cabin.
Finally, the utility model Optical Cables for Shipboard, can meet uvioresistant, oil resistant, the environmental requirement such as corrosion-resistant, can resist electromagnetic interference (EMI), meet safety standard, electrical isolation safety, produce without electric spark.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of instructions, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is existing Optical Cables for Shipboard structural representation.
Fig. 2 is the utility model light ship cable configuration schematic diagram.
Embodiment
for setting forth technological means, creation characteristic that the utility model realizes further, reaching object and effect is easy to understand, below in conjunction with accompanying drawing and preferred embodiment, to according to the utility model light ship optical cable embodiment, structure, feature and effect thereof, be described in detail as follows.
As shown in Figure 2, a kind of light ship optical cable of the utility model, comprises fiber unit, enhancement Layer 3, oversheath 4 and wire sheathing 5.
Described fiber unit is combined by least one optical fiber 1 and the nylon inner sheath 2 that is coated on outside of fiber.Described fiber unit external diameter is 1.0mm ~ 1.5mm.
In order to have, bending radius is little, endurance index is high and the carbon coated optical fiber of moisture-proof function for described optical fiber 1, and optical fiber can adopt the one in bare fibre, coated fiber, tightly packaged fiber.
The quantity of above-mentioned optical fiber 1 can be one or other radicals.
By stranded or directly put rear extrusion molding inner sheath 2 and form fiber unit between described optical fiber.
Evenly stranded in the outside of fiber unit have enhancement Layer 3, and enhancement Layer 3 can be aramid fiber or glass fibre or poly-to the two oxazole of benzo benzene or carbon fiber.
