The technology after improvement is had to be arranged at by two of optical cable optical fiber in two sheaths be connected; but such structure still cannot the exposed optical fiber of available protecting; install at optical cable simultaneously or be also inconvenient to operate in the process that uses; affect bending property; optical fiber is provided separately the problem of often weaken in addition, and the technology after improvement does not also solve very well.
Utility model content
For solving twin fiber cable protection imperfection in prior art, bending inconvenient, the insecure problem of intensity, the utility model provides a kind of protection perfect, bending convenient, the reliable twin fiber cable of intensity.
A kind of twin fiber cable, comprise optical fiber, the first reinforcement, the first sheath, the second reinforcement and the second sheath, described first sheath wraps up described optical fiber and described first reinforcement, described second reinforcement of described second sheath parcel, the number of described optical fiber, described first sheath and described first reinforcement is two, first sheath described in two is symmetrically set in described second sheath both sides, described second sheath comprises the first connecting band and the second connecting band, described first connecting band connects described first sheath, and described second connecting band connects the first sheath described in another.
According to a preferred embodiment of the present utility model, described first sheath comprises the first sheath body and tearing groove, and the xsect of described tearing groove is V-shaped, and described tearing groove is located at the both side surface of described first sheath parcel optical fiber.
According to a preferred embodiment of the present utility model, steel wire or the non-metal reinforcement member of described first reinforcement to be diameter be 0.5mm, the steel wire of described second reinforcement to be diameter be 1mm.
According to a preferred embodiment of the present utility model, the number of described first reinforcement is multiple, and multiple described first reinforcement is located at around described optical fiber.
According to a preferred embodiment of the present utility model, described first sheath and described second sheath are pe sheath.
In prior art, the optical fiber jacket of optical cable is connected; every root optical fiber is not completely wrapped; be unfavorable for optical fiber be torn after protection, the technical program improve after two described optical fiber are wrapped up completely by the first sheath described in two respectively, the described optical fiber after tearing can be protected well.Two optical fiber jackets of prior art are structure as a whole, and arrange described first connecting band and described second connecting band after improvement between described first sheath and described second sheath, bending to facilitate, and improve bending property.The reinforcement diameter of prior art is less, increases the diameter of described second reinforcement after improvement, arranges many reinforcements simultaneously, can improve the intensity of described twin fiber cable well around described optical fiber.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing described below is only embodiments more of the present utility model, for ability those of ordinary skill, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the cross-sectional view of the twin fiber cable that the utility model provides.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, carry out clear, complete description to the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.
Referring to Fig. 1, is the cross-sectional view of the twin fiber cable that the utility model provides.Described twin fiber cable 1 comprises optical fiber 11, first reinforcement 13, first sheath 15, second reinforcement 17 and the second sheath 19.Described first sheath 15 wraps up described optical fiber 11 and described first reinforcement 13, described second sheath 19 wraps up described second reinforcement 17, the number of described optical fiber 11 is two, and the number of described first sheath 15 is two, and the first sheath 15 described in two is symmetrically set in described second sheath 19 both sides.Described second sheath 19 comprises the second sheath body 191, first connecting band 193 and the second connecting band 195, described first connecting band 193 one end connects described second sheath body 191, the other end connects described first sheath 15, described second connecting band 195 one end connects the second sheath body 191 with the described first relative side of connecting band 193, and the other end connects the first sheath 15 described in another.
Described first sheath 15 comprises the first sheath body 151 and tearing groove 153.
Operationally, described first reinforcement 13 plays a part to support and tension described twin fiber cable 1, and it is positioned at described optical fiber 11 both sides, can improve the intensity of described twin fiber cable 1 comprehensively.Preferably, the number of described first reinforcement 13 is multiple, and multiple described first reinforcement 13 is arranged around described optical fiber 11.The number of described first sheath 15 is two, two described first sheaths 15 are symmetrically set in described second sheath 19 both sides, described first connecting band 193 and described second connecting band 195 are positioned at described second sheath body 191 both sides, and it connects two described first sheaths 15 of both sides respectively.Described first reinforcement 13 for diameter be steel wire or other non-metal reinforcement members of 0.5mm, multiple described first reinforcement 13 plays humidification jointly around described optical fiber 11.Described second reinforcement 17 is the steel wire of 1mm for diameter, can bear main pulling force.Described first connecting band 193 and described second connecting band 195 are made up of flexible nonmetal material, so it can be made to do rotation to a certain degree around described second sheath 19, handled easily when described first sheath 15 needs bending.
In prior art, the optical fiber jacket of optical cable is connected; every root optical fiber is not completely wrapped; be unfavorable for optical fiber be torn after protection, the technical program improve after two described optical fiber 11 are wrapped up completely by the first sheath 15 described in two respectively, the described optical fiber 11 after tearing can be protected well.Two optical fiber jackets of prior art are structure as a whole, and arrange described first connecting band 193 and described second connecting band 195 after improvement between described first sheath 15 and described second sheath 19, bending to facilitate, and improve bending property.The reinforcement diameter of prior art is less, increases the diameter of described second reinforcement 17 after improvement, arranges many described first reinforcements 13 simultaneously, can improve the intensity of described twin fiber cable 1 well around described optical fiber 11.
