Abstract
The utility model directs to a central-bundle tube-type optical fiber cable with a good bending performance and consists of an optical transmission element positioned in the central portion and a loose sleeve. A nonmetal reinforced element is arranged around the loose sleeve. The most outer layer of a cable core is wrapped with an outer protecting sleeve. The different point lies in that a longitudinal steel-strip-wrapped layer is arranged with the outer sleeve layer and the cable core. The optical transmission element is an optical fiber or an optical fiber strip. A water-resistance layer can be arranged outside the nonmetal reinforcing element in the cable core. The nonmetal reinforced element is a reinforced fiber element. The utility model has the beneficial effects: (1), the bending performance is good, various bending performances are identical, thus conveniently using and laying the optical fiber cable; (2), the longitudinal steel-strip-wrapped layer and the reinforced fiber element enhance the performance of resistance to the side pressure and the damp-proof performance, thus having a higher tensile strength; (3), having the advantages of a simple structure, a small diameter, a light weight and a lower manufacturing cost.
Description
Technical field
The utility model relates to a kind of central beam tube type optical cable with good bending property.
Background technology
The central beam tube type optical cable since have simple in structure, in light weight, cost of manufacture is low and use is laid characteristics such as convenient and has been widely used in field of communication transmission, use in pipeline and overhead communication line in a large number.Existing central beam tube type optical cable often adopts wire rope or FRP as reinforcement for strengthening its tensile strength, is symmetricly set on the both sides in the oversheath.The optical cable of this spline structure is crooked easily at above-below direction, on the plane that the both sides reinforcement is constituted, then be difficult to crooked, formed the bending direction of optical cable, made it be unsuitable for using in the occasion that requires optical cable to have good bending property, thereby to using and laying and brought inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is will overcome the deficiency that above-mentioned prior art exists and a kind of strong central beam tube type optical cable of good bending property and tensile property and lateral pressure resistant performance that has is provided.
The utility model is to address the above problem the technical scheme that is proposed to be: comprise the light conducting piece and the loose sleeve pipe 4 that are arranged on the centre, the pine sleeve pipe is equipped with non-metal reinforcement member 5 outward, the outermost layer parcel oversheath 8 of cable core, its difference is to be provided with vertical Baogang belt 7 between oversheath and cable core.
Press such scheme, described smooth conducting piece is optical fiber 1 or fibre ribbon 2; Can lay water blocking layer 6 outside the non-metal reinforcement member in cable core, water blocking layer is made of waterstop (yarn); Described non-metal reinforcement member 5 is aramid yarn or glass fibre, also can be other fiber reinforcement.
The beneficial effects of the utility model are: 1, have good bending property, and every bending property is identical, this is to using and laying and brought convenience; 2, adopt vertical Baogang's belt and fiber reinforcement that the lateral pressure resistant performance of optical cable and humidity resistance are strengthened, and possess advantages of higher tensile strength; 3, have simple in structure, diameter is little, in light weight and characteristics that cost of manufacture is low.
Description of drawings
Fig. 1 cuts open figure for the lateral cross section of an embodiment of the utility model.
Fig. 2 cuts open figure for the lateral cross section of another embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.First embodiment as shown in Figure 1, be set with optical fiber 1 in the pine sleeve pipe 4, be arranged on the centre of cable core, be filled with fine cream 3 in the pine sleeve pipe, outside loose sleeve pipe, be equipped with non-metal reinforcement member 5, constitute by aramid yarn or glass fibre, also be wound with water blocking yarn outside non-metal reinforcement member, constitute water blocking layer 6, each part mentioned above is a cable part, be coated with vertical Baogang belt 7 at cable core, form steel-tape armouring, coat oversheath 8 outside vertical Baogang belt, oversheath can be the PE sheath, also can be the halogen-free flameproof sheath, constitute the central beam tube type optical cable thus.
Second embodiment of the utility model as shown in Figure 2, the main difference of it and a last embodiment is to be equipped with fibre ribbon 2 in the loose sleeve pipe 4, fibre ribbon can be that one or more is superimposed.All the other structures are identical with a last embodiment.
