Abstract
The utility model relates to an optical fiber pigtail, this optical fiber pigtail include capillary, optic fibre and set up the optical fiber pigtail afterbody be used for fixedly and the glued of protection optic fibre constructs, wherein, glued construct glue fixed knot by the three -layer and constitute, the three -layer glue the fixed knot structure for the hard rubber layer that is used for the fixed fiber, be used for protecting the flexible glue layer of optic fibre and be located hard rubber layer and the flexible glue layer between the transition glue film, just hard rubber layer is close to optical fiber pigtail's afterbody. The utility model discloses an optical fiber pigtail glues through set up the one deck transition in the gluing constructs, plays the effect of stress buffering, makes this kind of optic fibre can not only the fixed fiber simultaneously, can also protect optic fibre, and the anti side that has improved optical fiber pigtail draws the ability, reduces using the fine risk of process interrupt.
Description
Technical field
This utility model is related to optical-fibre communications field, in particular it relates to a kind of optical fiber pigtail.
Background technology
In the prior art, optical fiber pigtail is generally by capillary tube 1, optical fiber 2, solidification glue 3 and 4 groups of fiber optic protection flexible glue
Become, but this structure is more much larger than the hardness of fiber optic protection flexible glue 4 due to the hardness of solidification glue 3, when optical fiber 2 is in side draw
Effect is lower easily to be damaged, or even fracture.
Content of the invention
The purpose of this utility model is to overcome the defect of prior art and deficiency, provides optical fiber pigtail, and this kind of tail optical fiber leads to
Cross and directly one layer of transition glue is set so that this kind of optical fiber can not only fix optical fiber moreover it is possible to protect in solidification glue and fiber optic protection flexible glue
Shield optical fiber, and improve the anti-side pulling ability of optical fiber pigtail, reduce fine risk of breaking in use.
In order to achieve the above object, this utility model provides a kind of optical fiber pigtail, and described optical fiber pigtail includes capillary tube, light
The plastic structure for fixing and protecting described optical fiber that is fine and being arranged on described optical fiber pigtail afterbody, described plastic structure is by three layers
Glue fixed structure is constituted, and described three layers of glue fixed structure are for fixing the ebonite layer of optical fiber, the flexible glue layer for protecting optical fiber
And it is located at the transition glue-line between described ebonite layer and flexible glue layer；And described ebonite layer is near the afterbody of described optical fiber pigtail.
According to an embodiment of the present utility model, in described transition glue-line, the hardness of glue becomes steps change, the closer to
The part of described ebonite layer is closer to the hardness of described ebonite layer；The closer to described flexible glue layer part closer to described flexible glue layer
Hardness.
According to an embodiment of the present utility model, described optical fiber pigtail also includes being enclosed within described optical fiber pigtail afterbody and glue
The sleeve pipe on structure top layer.
According to an embodiment of the present utility model, described sleeve pipe is metal or glass bushing.
This utility model, with respect to prior art, has the advantages that：By arranging one layer of transition in plastic structure
Glue, plays the effect of stress buffer, makes this kind of optical fiber can not only fix optical fiber moreover it is possible to protect optical fiber simultaneously, and improves light
The anti-side pulling ability of fine tail optical fiber, reduces fine risk of breaking in use.

Specific embodiment
With reference to embodiment and accompanying drawing, this utility model is described in further detail, but reality of the present utility model
Apply mode not limited to this.
As shown in Fig. 2 for optical fiber pigtail of the present utility model structural representation, this optical fiber pigtail include capillary tube 10,
Optical fiber 20 and the plastic structure for fixing and protecting optical fiber 20 being arranged on optical fiber pigtail afterbody, this plastic structure is solid by three layers of glue
Fixed structure is constituted, and three layers of glue fixed structure are for fixing the ebonite layer 31 of optical fiber 20, the flexible glue layer 33 for protecting optical fiber 20
And it is located at the transition glue-line 32 between ebonite layer 31 and flexible glue layer 33；And ebonite layer 31 is near the afterbody of optical fiber pigtail.
In embodiment of the present utility model, in transition glue-line 32, the hardness of glue becomes steps change, the closer to ebonite layer 31
Part closer to ebonite layer 31 hardness；The closer to flexible glue layer 33 part closer to flexible glue layer 33 hardness.
In embodiment of the present utility model, optical fiber pigtail also includes the set on unjacketed optical fiber tail optical fiber afterbody top layer and plastic structure top layer
Pipe 40, this sleeve pipe 40 is usually metal or glass bushing.
In sum, optical fiber pigtail of the present utility model passes through to arrange one layer of transition glue 32 in plastic structure, plays stress
The effect of buffering, makes this kind of optical fiber can not only fix optical fiber moreover it is possible to protect optical fiber simultaneously, and improves the anti-side of optical fiber pigtail
Draw ability, reduce fine risk of breaking in use.
Above-described embodiment be this utility model preferably embodiment, but embodiment of the present utility model be not subject to above-mentioned
The restriction of embodiment, other any do not run counter to the change made under spirit of the present utility model and principle, modifies, replaces
Generation, combination, simplification, all should be equivalent substitute mode, are included within protection domain of the present utility model.
