Description
Technical field
The utility model relates to a kind of flexible non-metallic optical fiber cables of strengthening structure that has, applicable to central tubular that comprises single fiber form or fibre ribbon form and/or layer-twisted type non-metallic optical fiber cables.
Background technology
Since optical cable might with the power cable laying in one ditch, and consider for factors such as anti-electromagnetic distu, anti-thunders and lightnings, need optical cable to have the design of complete nonmetal characteristic or anti-thunder and lightning at a lot of environment.Reinforcement structure as optical cable, at present known more be to adopt the nonmetal reinforcement yarns such as aramid fiber that in optical cable, use stranded form, or as the form of the nonmetal stirrup of strip or oval thing shape, and some reinforcement also is designed to be embedded into the version in the cable outer sheath.Adopt the reinforcement structure of nonmetal reinforcement yarn form, stranded factor will influence the effect of reinforcement, so it can only be as the auxiliary reinforcing element of optical cable, and mainly is applied to the self-support aerial cable structure parallel with power circuit limitedly.When using the nonmetal stirrup of strip or oval thing shape to embed the structure of cable jacket, the more special equipment of general normal needs, and can increase the external diameter of optical cable, construction causes difficulty to fiber cable laying.
As the present common nonmetal or lightning protection electrical-optical cable structure of layer-twisted type structure, be that ferrule is stranded on the non-metal reinforcement member, outside the cable core that forms thus, wrap the nonmetal reinforcement yarn of some to guarantee the mechanical property of optical cable necessity with the winding form again.In being the Chinese patent literature of CN2509589Y, notification number disclosed the optical cable of two kinds of center tube structure, the form of its nonmetal reinforcement structure is a kind of to be to coat non-metal reinforcement member outside sleeve pipe, and another kind of form adopts the rope form non-metal reinforcement member is set in sheath.In Chinese patent CN87103827, employing be a kind of design that individual layer or double glazing fibre composites club shaped structure are set in sheath.Nonmetal yarn as the stranded form of simple employing coats, and can make optical cable lack enough counter-bending elements; As adopt the form that adds bar-shaped non-metal reinforcement member, though improved the bending resistance of optical cable, but the weight and the external diameter of optical cable have been increased inevitably, cause the difficulty in the fiber cable laying process, and how bar-shaped non-metal reinforcement member embeds difficulty and cost that sheath has also increased optical cable production simultaneously.
The utility model content
At above-mentioned situation, the utility model will provide a kind of flexible non-metallic optical fiber cables of strengthening structure of new structure form that can effectively overcome the deficiency of above-mentioned various versions, it is become to have certain vertically physical strength, have certain amount of deflection again thereby also have certain bend resistance performance, has the external diameter that both can reduce optical cable again, and it is simple in structure, production technology is simplified, and technology stability is good, the characteristics that production cost is lower can be widely used in the optical cable (comprising single fiber or optical fibre band optical cable form) of various ways such as layer-twisted type structure and/or central tubular structure.
The utlity model has the flexible non-metallic optical fiber cables of strengthening structure, be the optical cable core structure that in the cable outer sheath unit, is provided with single fiber/fibre ribbon form equally, wherein, between cable outer sheath unit and optical cable core structure, be provided with by the flexibility of fiber glass reinforcement (GRP) the longitudinal sleeve tubular construction form that band became and strengthen structural unit.
With regard to the non-metallic optical fiber cables that the optical cable core structure is the center tubular type, the flexibility of the fiber glass reinforcement band longitudinal sleeve tubular construction form in the said structure is strengthened structural unit, can adopt the form between two parietal layers that are arranged on cable outer sheath unit and cable core pine sleeve pipe, it is opened as optical cable vertically anti-and/or laterally resistance to compression, bend resistance element.
For the optical cable core structure is the non-metallic optical fiber cables of layer-twisted type, then the flexibility of the fiber glass reinforcement band longitudinal sleeve tubular construction form in the said structure is strengthened structural unit, can adopt along the set-up mode of cable outer sheath unit inner wall layer, it is opened as optical cable vertically anti-and/or laterally resistance to compression, bend resistance element.
In the non-metallic optical fiber cables of the flexible reinforcement structure of having of said structure form, strengthen structural unit for described flexibility of being somebody's turn to do the longitudinal sleeve tubular construction form that is become by the GRP band, a kind of mode of reference example when can be used as concrete enforcement, be to adopt the band that forms through adhesives by glass fibre, its width can be tens millimeters to tens millimeters, thickness is 0.5 millimeter to 1.2 millimeters, is further formed the structure of longitudinal sleeve form of tubes again by it.The nonmetal reinforcing element that this flexible GRP band that is formed by adhesives by glass fibre can have satisfied vertical physical strength owing to itself have certain amount of deflection, therefore also can have certain bend resistance performance simultaneously simultaneously.
Obviously, after the flexibility that adopts flexible GRP band described in the utility model to form longitudinal sleeve tubular construction form in the non-metallic optical fiber cables of central tubular is strengthened structural unit, the cable outer diameter that makes that the bar-shaped reinforcement structure of embedding is caused in sheath that both can avoid adopting at present becomes big defective, also be better than simultaneously adopting and outside sleeve pipe, coat non-metal reinforcement member, especially the mode of nonmetal reinforcement yarn such as aramid fiber, avoided because of nonmetal reinforcement yarn owing to there is the stranded defective that unbalance stress occurs, thereby have good practicability.For the layer-twisted type non-metallic optical fiber cables, adopt the auxiliary reinforcing element of the longitudinal sleeve tubular construction of flexible GRP band formation described in the utility model as the optical cable central reinforce member, also can guarantee and improve the mechanical property of optical cable.Especially for the optical cable of band structure of optic fibre, because the increase of optical cable deadweight, the center non-metal reinforcement member can not unrestrictedly increase (also unreasonable), and increasing auxiliary reinforcement element will be a kind of feasible measure.Adopt version described in the utility model to use flexible GRP band to become the longitudinal sleeve tubular construction to replace the normally used nonmetal reinforced wire expensive, also will make such optical cable have more economy as aramid fiber material or glass fiber/braid over braid etc.
According to foregoing, under the prerequisite that does not break away from basic fundamental thought described in the utility model,, modification, replacement or the change of various ways can also be arranged to its content according to the ordinary skill knowledge and the customary means of this area.
Below in conjunction with embodiment, described content of the present utility model is described in further detail again by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.All technology that is realized based on the utility model foregoing all belong to scope of the present utility model.
