Specific embodiment
In order to more fully understand the technology contents of the utility model, with reference to specific embodiment to the skill of the utility model
Art scheme is further described and illustrates, but not limited to this.
Referring to Fig. 1, present embodiments providing a kind of wiring optical cable 1, including cable core 12 and it is coated on 12 periphery of cable core
Sheath 11, cable core 12 includes multifiber unit 121, and 121 periphery of fiber unit is coated with tight sleeve layer 122, right in sheath 11
Title is provided with two reinforcements, and the both direction that 11 outer surface of sheath deviates from reinforcer is equipped with strip bulge 111, strip bulge
111 with 11 integral molding of sheath.Wherein, other fillers need not be added between cable core 12 and sheath 11, make be between the two
Free fluffy.It changes in external temperature environment or during by external force, has enough spaces as buffer strip, avoid influencing
To the normal data transfer of optical fiber.Preferably, the both direction that is set with reinforcer of both direction that strip bulge 111 is set is in
Mutually orthogonal relationship, in this way, when connecting up bending, the influence to reinforcer is minimum.In addition, it can facilitate when detaining core
Efficiently in 11 surface of the sheath fluting for being symmetrically distributed with the both direction of strip bulge 111, and offset will not be generated, avoid by
Reinforcer is cut off, so as to influence the tensile property of whole optical cable.
Further, sheath 11 is located at the wall thickness of 111 both direction of strip bulge and is located at reinforcer two less than sheath 11
The wall thickness in direction makes 11 Inner Constitution elliptical shape of sheath.Because sheath 11 be located at the wall thickness of 111 both direction of strip bulge compared with
Small, optical cable reduces required bending force, is connected up in construction in the both direction bending for having strip bulge 111 to surface
It is more convenient in the process.Meanwhile setting accordingly increases the space of optical cable endoporus in this way so that optical cable can possess better temperature
Environmental performance and attenuation characteristic.For optical cable in the both direction bending for having strip bulge 111 to surface, the endoporus of bending direction is straight
Diameter can be compressed, and the diameter of bore perpendicular to bending direction can be stretched, oval bore design, and bending is generated in optical cable
When, can preferably ensure the uniformity of optical cable pore space, so as to optimize optical cable in the temperature environment performance of bending and
Attenuation characteristic.
Preferably, reinforcer is a diameter of 1.0mm fiberglass reinforced plastics stick 112.Fiberglass reinforced plastics stick 112
It is a kind of using macromolecule epoxy resin as matrix, glass fiber or carbon fiber etc. are reinforcement, by compound made of combination process
Material.Fiberglass reinforced plastics stick 112 is light, insulation, environmental protection flame retardant, bending resistance tensile strength are high, corrosion-resistant, anti-aging, line
The coefficient of expansion is small, water absorption rate is low, percent thermal shrinkage is substantially zeroed, and many merits cause it to be widely applied in optical cable, to improve light
The performances such as tension, resistance to compression, bending resistance, anti-shrink, the rock-steady structure of cable.It is done using two 1.0mm fiberglass reinforced plastics sticks 112
Symmetrically be embedded in inside sheath 11 for reinforcer, can cause optical cable by it is each to bending force when should not bend, can cause
Optical cable should not be twisted together when by twisting resistance, so as to construction lay or use in preferably protect optical cable.Meanwhile increase light
11 wall thickness of sheath of cable, so as to improve the resistance to compression of optical cable, shock resistance.
Specifically, fiber unit 121 is 12~48, in the present solution, can generally achieve 48.Fiber unit 121 can
Different types of single mode or multimode fibre are selected according to the application demand of client.Tight sleeve layer 122 is low smoke halogen-free flame-retardant polyolefin
Material or polyvinyl chloride material.Preferably, a diameter of 0.9mm of tight sleeve layer 122.Tight sleeve layer 122 can also be better nylon
(Nylon) or thermoplastic polyester elastomer (Hytrel) material.Tight sleeve layer 122 can be subject to area using different colours or mark
Point.
Specifically, sheath 11 is low smoke halogen-free flame-retardant polyolefin material.Sheath 11 also can according to client's wiring environment demand,
The performances sheaths 11 such as uvioresistant may be selected, various colors can also be made, it is specious to optical cable to meet resident family
Demand.
Summary：A kind of wiring optical cable of the utility model by 11 outer surface of sheath perpendicular to two sides of reinforcer
To setting strip bulge 111, in cable wiring manufacture, it is capable of the direction of intuitive judgment reinforcer setting, when avoiding wiring bending, to
Direction bending equipped with reinforcing element, effectively prevents the problem of optical cable easily causes reinforcer fracture in bending, so as to carry
The high efficiency of cable wiring manufacture；In addition, when detaining core, construction personnel can slot on strip bulge 111, and will not generate partially
The problem of moving, effectively preventing easily cutting off reinforcer during fluting.
The above-mentioned technology contents that the utility model is only further illustrated with embodiment, in order to which reader is easier to understand,
But the embodiment for not representing the utility model is only limitted to this, any technology extension or recreation done according to the utility model,
