Description
Technical field
This utility model relates to optical cable field, particularly relates to the double butterfly leading in cable of a kind of self-bearing type.
Background technology
Along with the continuous popularization of China's network technology, optical cable industry obtains high speed development, creation of new enterprise quantity constantly on
Rising, industry overall technology level is largely increased, and cost constantly reduces, and has promoted the most universal of information network.Butterfly light
Cable, owing to being prone to line taking construction, is applied more in indoor place, and the structure of existing butterfly optical cable is, sheath is provided with V-arrangement
Breach, and be provided with metal material or the strengthening core of the spacing material of glass, but still suffer from following shortcoming with said structure: 1, steel wire
Strengthening core material is harder, there is resilience tendency after bending, when the little bending of optical cable lays, owing to being affected by steel wire resilience,
Cable jacket is more easily damaged, and optical fiber is more vulnerable to lateral additional stress；Steel wire strengthening core from straightforward poor, optical cable bending after
Being difficult to recover, optical fiber is easily subject to damage, and in construction and laid processes, optical cable is susceptible to beat turns round phenomenon, and this can make optical fiber
Suffer internal injury, 2, use easily the fractureing of glass fibre, also can reduce the life-span of optical fiber；3, traditional butterfly optical cable is simple root
, it is to use both threads material when needs introduce multifiber, uses inconvenience.
Utility model content
For solving above-mentioned technical problem, the utility model proposes the double butterfly leading in cable of a kind of self-bearing type, including strengthening
Steel band, described reinforcement steel band both sides are provided with butterfly retraction mechanism, are provided with between described butterfly retraction mechanism and described reinforcement steel band
Cross structure；Described butterfly retraction mechanism includes that two integrated cross sections are circular sheath, inside described sheath junction
It is provided with optical fiber, in two described sheaths, is provided with three tangent strengthening cores of circumference；Described outer fiber is provided with protection set, described light
It is filled with fine cream between fine and described protection set.
Preferably, the thickness between described sheath junction is 0.9mm.
Preferably, it is provided with screen layer outside described reinforcement steel band.
Preferably, described strengthening core for aramid fiber reinforcing optical cable reinforced core.
Preferably, the material of described sheath is flame-retardant polyolefin sheathed.
The double butterfly leading in cable of the self-bearing type that the utility model proposes has following beneficial effect: this optical cable uses many reinforcements
Optical cable is reinforced by core so that the distance between strengthening core and sheath is uniform, increases steadiness, prevents from damaging optical fiber, and
Use the structure of double butterfly-type, use a wire rod can get final product bracing wire, it is not necessary to introduce two, additionally, use aramid fiber to strengthen
Optical cable strengthening core, itself softness is good, is not easily broken, and improves wire quality.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, required in embodiment being described below
Accompanying drawing to be used is briefly described.
Fig. 1 is structural representation of the present utility model；
Wherein, 1-strengthens steel band, 2-butterfly retraction mechanism, 3-cross structure, 4-sheath, 5-optical fiber, and 6-protects set, and 7-is fine
Cream, 8-screen layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
As it is shown in figure 1, the utility model proposes the double butterfly leading in cable of a kind of self-bearing type, including strengthening steel band 1, described
Strengthen steel band 1 both sides and be provided with butterfly retraction mechanism 2, between described butterfly retraction mechanism 2 and described reinforcement steel band 1, be provided with cross structure
3, use cross structure 3 to make steel band away from problems such as optical fiber 5, the electromagnetic interference that reduction steel cause；Described butterfly retraction mechanism 2
It is circular sheath 4 including two integrated cross sections, inside described sheath 4 junction, is provided with optical fiber 5, two described sheaths
It is provided with three tangent strengthening cores of circumference in 4, uses three strengthening cores to add reinforcement intensity, meanwhile, compare original one and add
Qiang Xin, if processing unreasonable, causes a strengthening core center to vary to the distance at sheath 4 edge, when there is pressure in the external world,
Uneven for accepting of optical fiber 5 so that optical fiber 5 fractures, and uses three strengthening cores can add the horizontal stroke of whole strengthening core
Cross section, adds protection cotton knot；The outside protection set 6 that is provided with of described optical fiber 5, is filled with between described optical fiber 5 and described protection set 6
Fine cream 7.
Preferably, the thickness between described sheath 4 junction is 0.9mm, uses the sheath 4 of circle, easy making process, uses
The mode of extrusion so that each sheath 4 structure is fixed, the line that the cylindrical point intersected is formed is for tearing place, and ensures that it is thick
Degree is 0.9, is the thickness being easiest to tear, and the optical fiber 5 at the place of not tearing both will not be made to be drawn out, simultaneously also will not be the most laborious
Sheath 4 is torn.
Preferably, described reinforcement steel band 1 is outside is provided with screen layer 8, increases screen layer 8 and ensures that the self-supporting of metal material is strengthened
Steel band 1 affects optical fiber 5 and works.
Preferably, described strengthening core for aramid fiber reinforcing optical cable reinforced core, use aramid fiber to strengthen optical cable and strengthen
Core, itself softness is good, is not easily broken, and improves wire quality.
Preferably, the material of described sheath 4 is flame-retardant polyolefin sheathed 4, prevents high temperature from causing sheath 4 to damage.
Multiple amendment to embodiment will be apparent from for those skilled in the art, herein institute
The General Principle of definition can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.
Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to former with disclosed herein
The widest scope that reason is consistent with features of novelty.
