Yet existing easily branched optical cable, link into an integrated entity between tight tube fiber and oversheath, usually when optical fiber needs branch maybe to need to peel off, the cost manpower and materials are larger, and very difficult, accidentally also easily inner tight tube fiber caused to damage.Simultaneously, existing inside cable diameter is large, and preponderance is very difficult when wiring.
Chinese Patent Application No.: CN201220688036 discloses the easily branched optical cable of the parallel reinforcement of a kind of interior ellipse, comprise optical fiber, FRP reinforcement and oversheath, optical fiber is positioned at innermost layer, the FRP reinforcement is symmetrically distributed in around optical fiber, oversheath is positioned at outermost layer, and FRP reinforcement and optical fiber are coated, oversheath is provided with a pair of stripping point mark, fill around optical fiber and form elliptical shape, this cable outer diameter is little, lightweight, density of optic fibre is high, facilitate stripping, be particularly useful for commercial office building comprehensive wiring, but this optical cable and optical fibres directly is placed in the oval chamber that oversheath is rolled into, the mutual extrusion and collision of bare fibre, decay transporting and stability are low.
Chinese Patent Application No.: CN200910220962 discloses a kind of easily branched optical cable, comprise the central reinforce member (6) that at least comprises a loose sleeve pipe (3), one and be positioned at the optical cable center, integral coating central reinforce member outer jacket (5), be coated on the outer messenger wire (1) of loose sleeve pipe (3) and connect the muscle (2) of messenger wire (1) and outer jacket (5); At least comprise a light transmitting fiber (4) in described loose sleeve pipe; Described messenger wire (1) and muscle (2) around outer jacket (5) distribute and adjacent messenger wire between, all gapped between muscle; That described messenger wire (1), muscle (2), outer jacket (5) are formed as one and for commaterial, such optical cable volume is little, fiber capacity is large, easy to process, optical fiber property stability is strong, but this optical cable weight is large, is not suitable for the optical fiber layout type of office building.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of external diameter little, lightweight, density of optic fibre is high, and capacity is large, and the optical cable outside surface has convex stripping point mark, can peel off easily the interior oval-shaped easily branched optical cable that optical fiber carries out branch operation.
The objective of the invention is to be achieved through the following technical solutions: a kind of interior oval-shaped easily branched optical cable, it comprises tight tube fiber, interior dead level, non-metal reinforcement member, oversheath and convex stripping point; Tight tube fiber is arranged in interior dead level, and interior dead level periphery is oversheath, and the outside surface of oversheath is provided with convex stripping point, and oversheath inside is provided with at least two non-metal reinforcement members.
Described interior dead level is oval-shaped hollow structure.
Described convex stripping point is arranged at the weakness of oversheath wall thickness.
The quantity of described convex stripping point includes but are not limited to two.
Described non-metal reinforcement member is made by the FRP material.
Described non-metal reinforcement member is arranged at oversheath wall thickness thickness.
Axial line and the tight tube fiber of described non-metal reinforcement member are positioned on same level.
Described oversheath diameter is no more than 12mm.
The present invention has the following advantages:
1. the cable outer sheath diameter is no more than 12mm, and external diameter is little, lightweight, moves and lays very convenient;
2. in the oversheath the inside, stretch-proof and compressive property are good by bale breaking for tight tube fiber;
3. oversheath is built-in with and comprises at least one pair of FRP reinforcement, makes stretch-proof ability and the flexibility of optical cable stronger;
4. the optical cable outside surface has the stripping mark, in any position, can put in a skylight, and the light unit in pipe is extracted out easily, is conducive to the stripping branch of optical cable;
Can with the dividing box fit applications, according to the wiring demand, arbitrarily lay;
6. can divide router etc. to coordinate all-optical network to lay with indoor butterfly optical cable wire jumper and light.
The accompanying drawing explanation
Fig. 1 is cross sectional representation of the present invention;
In figure, 1-tight tube fiber, dead level in 2-, 3-non-metal reinforcement member, 4-oversheath, 5-convex stripping point.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, a kind of interior oval-shaped easily branched optical cable, it comprises tight tube fiber 1, interior dead level 2, non-metal reinforcement member 3, oversheath 4 and convex stripping point 5; Tight tube fiber 1 is arranged in interior dead level 2, and interior dead level 2 peripheries are oversheath 4, and the outside surface of oversheath 4 is provided with convex stripping point 5, and oversheath 5 inside are provided with at least two non-metal reinforcement members 3.
