Abstract
The invention discloses a kind of double optical fiber cables of high intensity, include section into the insulation body of track type, the insulation sleeve body is interior to be provided with two fibre cores, and two high intensity cotton ropes are additionally provided between two fibre cores；Two sides of the insulation body are provided with corrugated buffering line；Upper and lower part in the insulation sleeve body is equipped with multiple hollow pipes being arranged side by side；Left and right ends in the insulation sleeve are equipped with multiple rigidity bars；Length direction equidistant arrangement of the rigidity bar along insulation body per one end；Pass through the high intensity cotton rope of setting; it is effectively increased its stretching rigidity; and cushion and hollow pipe are designed to be effectively increased its bending ability, cable will not be caused excessively to ossify, loss problem after the rigidity bars of both sides can effectively protect the cable left and right sides pendulum excessive.
Description
Technical field
The present invention relates to a kind of double optical fiber cables of high intensity.
Background technology
At present, optical fiber is optical fiber, and it is used to transmit information, is the indispensable product in the communications field, at present optical fiber
Spoilage it is high, most important is exactly that it is easily broken, or bending angle is excessive, causes fibre core to be damaged, and causes critical angle change greatly,
Optical fibre damage.
The content of the invention
It is an object of the invention to overcome disadvantages described above, there is provided a kind of double optical fiber cables of high intensity.
To achieve the above object, concrete scheme of the invention is as follows：A kind of double optical fiber cables of high intensity, include section into
The insulation body of track type, the insulation sleeve body is interior to be provided with two fibre cores, and two high intensity cotton ropes are additionally provided between two fibre cores；
Two sides of the insulation body are provided with corrugated buffering line；
Upper and lower part in the insulation sleeve body is equipped with multiple hollow pipes being arranged side by side；Left and right in the insulation sleeve
Both ends are equipped with multiple rigidity bars；Length direction equidistant arrangement of the rigidity bar along insulation body per one end.
Wherein, the hollow pipe is identical with the diameter of high intensity cotton rope.
Wherein, high intensity cotton rope is steel wire cotton rope.
Wherein, insulation body is provided with multiple label snap rings being placed equidistant along its length.
Beneficial effects of the present invention are：By the high intensity cotton rope of setting, its stretching rigidity, and cushion are effectively increased
It is designed to be effectively increased its bending ability with hollow pipe, cable will not be caused excessively to ossify, the rigidity bar of both sides can
The effectively excessive rear loss problem of protection cable left and right sides pendulum.

Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not the reality the present invention
Apply scope and be confined to this.
As shown in Figure 1 to Figure 3, the double optical fiber cables of a kind of high intensity described in the present embodiment, include section into track type
Insulation body 1, it is described insulation body 1 in is provided with two fibre cores 3, be additionally provided with two high intensity cotton ropes 4 between two fibre cores 3；
Two sides of the insulation body 1 are provided with corrugated buffering line 2；
Upper and lower part in the insulation body 1 is equipped with multiple hollow pipes 6 being arranged side by side；A left side in the insulation sleeve
Right both ends are equipped with multiple rigidity bars 5；Length direction equidistant arrangement of the rigidity bar 5 along insulation body 1 per one end.Pass through
The high intensity cotton rope 4 of setting, be effectively increased its stretching rigidity, and cushion and hollow pipe 6 are designed to be effectively increased
It bends ability, and cable will not be caused excessively to ossify, and the rigidity bar 5 of both sides can effectively protect the excessive rear damage of cable left and right sides pendulum
Mistake problem.Two fibre cores 3 can also be set in same cable, improve product efficiency.Its concrete principle is upper and lower wave
The buffering line 2 of shape can effectively reduce bending energy by a small margin, reduce the aging of insulating coating.Air-conditioning duct is that second is prevented
Line, the bending energy of moderate strength can be reduced.Rigidity bar 5 and high intensity cotton rope 4 are threes lines of defence, can effectively be organized
Infringement of the bending and tensile energy of high intensity to cable.The especially design of rigidity bar 5, it is intermittent type, it can allow line
Cable bend in the case of ensure will not bending angle it is excessive.
The double optical fiber cables of a kind of high intensity described in the present embodiment, the diameter of the hollow pipe 6 and high intensity cotton rope 4 are big
It is small identical.
The double optical fiber cables of a kind of high intensity described in the present embodiment, high intensity cotton rope 4 is steel wire cotton rope.
The double optical fiber cables of a kind of high intensity described in the present embodiment, insulation body 1 is provided with multiple equidistant along its length
The label snap ring 7 of setting.
Described above is only the preferred embodiment of the present invention, therefore all structures described according to present patent application scope
Make, the equivalent change or modification that feature and principle are done, in the protection domain of present patent application.
