Abstract
The utility model discloses a super gentle resistant curved low friction butterfly -shaped introducing optical cable, the center is optic fibre, the optic fibre both sides are provided with the reinforcement, the reinforcement is provided with the sheath outward, the sheath cross section ellipse of matching. The beneficial effects of the utility model reside in that adopt bielliptic(al) butterfly configuration design, reduce the area of contact of butterfly -shaped introducing optical cable and pipeline, reduce coefficient of friction effectively.
Description
Technical field
The utility model relates to a kind of super soft bending resistance low friction butterfly leading in cable, is applied in Access Network fiber to the home, coordinates quick coupler, be connected to quickly and easily on indoor terminal equipment.
Background technology
The last one kilometer that fiber to the home is built, butterfly leading in cable plays very important effect, people have deepened to concrete material object to the understanding of butterfly leading in cable by the noun in past, can say that butterfly leading in cable can find in the multimedia information box of every household.But in reality construction, we often have so a kind of difficult situation: should wear butterfly leading in cable in the pipeline of registering one's residence, sometimes also have other cable also will wear this root to register one's residence pipeline, our butterfly leading in cable just can not guarantee to pierce into like this, more often butterfly leading in cable is just stuck in certain corner of pipeline, and advance and retreat must not.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of super soft bending resistance low friction butterfly leading in cable.
In order to realize foregoing invention object, the utility model adopts following technical scheme:
A kind of super soft bending resistance low friction butterfly leading in cable, center is optical fiber, and described optical fiber both sides are provided with reinforcement, and described reinforcement is outside equipped with sheath; Described sheath xsect becomes bielliptic(al) shape.
Preferably, described sheath both sides are provided with depression.
Beneficial effect of the present utility model is, global design is reasonable, and compact conformation, fabrication processing is reliable.The super soft bending resistance low-friction coefficient butterfly leading in cable made through the utility model has following features: adopt the configuration design of bielliptic(al) butterfly, reduce the contact area of butterfly leading in cable and pipeline, effectively reduce friction factor.Adopt high strength fibre as reinforcement propping material, ensure that the tensile property of butterfly leading in cable, there is outstanding resist bending fracture resistance simultaneously.Add lubricant material when sheath, not only improve the environmental-protecting performance of butterfly leading in cable, use again optical cable to have lower friction factor, improve the efficiency of poling.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Wherein, 1 is optical fiber, and 2 is reinforcements, and 3 is sheaths.
Embodiment
Below with reference to accompanying drawing, the utility model is described in further detail.
With reference to accompanying drawing 1, optical fiber 1 is placed in the centre position of butterfly leading in cable, and in the both sides of optical fiber 1, correspondence places reinforcement 2, and then outside entirety extrudes sheath 3, adds lubricant when extruding sheath.
As the reinforcement of butterfly leading in cable after the fiber solidifying one-tenth bar of employing special high-strength, two side by side parallel are placed in the position, both sides of optical cable, optical fiber is placed in the centre position of butterfly leading in cable, sheath adopts low-smoke halogen-free polyolefin material, add at sheath material the friction factor that lubricant reduces protective cover material simultaneously, optical fiber and reinforcement are placed in the middle of sheath respectively, in the major axis side interposition of butterfly optical cable, circular arc type depression is set, butterfly optical cable rectangular configuration change in design is simultaneously circular-arc-shaped design, and whole cable cross-section is bielliptic(al) shape.
Oval in outline shape, reduces the contact with pipeline, reduces friction factor; By adding lubricant in sheath, improving smooth finish and the smoothness of jacket surface, reducing friction factor; Adopt high strength fibre as reinforcement, its bending radius is little, and most I reaches 7.5mm, reaches the effect of super soft resistance to bending.
Although the utility model with preferred embodiment openly as above; but they are not for limiting the utility model, anyly haveing the knack of this those skilled in the art, not departing from the spirit and scope of the utility model; can make various changes or retouch, all within protection domain of the present utility model from working as.What therefore protection domain of the present utility model should define with the claims of the application is as the criterion.
Claims (2)
1. a super soft bending resistance low friction butterfly leading in cable, is characterized in that, center is optical fiber, and described optical fiber both sides are provided with reinforcement, and described reinforcement is outside equipped with sheath; Described sheath xsect becomes bielliptic(al) shape.
2. the super soft bending resistance of one according to claim 1 low friction butterfly leading in cable, it is characterized in that, described sheath both sides are provided with depression.
