Description
Technical field
The present invention relates to optical fiber heat-shrink tube, and in particular to multi-core fiber continues the middle heat-shrink tube used.
Background technology
Optical fiber heat-shrink tube refers to single-core fiber pyrocondensation protection sleeve pipe, and single-core fiber pyrocondensation protection sleeve pipe is mainly used in single light
The naked fibre part that fibre continues, inner tube are tempreature bulb, and centre lining reinforcer, outer tube is transparent heat-shrinkable tube.Reinforcer is generally
Stainless steel is held in both hands, quartz is held in both hands or ceramics are held in both hands.Optical fiber is the important component for forming optical communication system, and it provides optical signal transmission
Passage.Optical fiber is generally made up of fibre core, covering and coat.Fibre core and covering are all high-purity silicon dioxides, due to doping
The ratio of agent doping is different, makes the refractive index of fibre core higher than the refractive index of covering, and loss ratio covering is low, therefore light energy master
To be transmitted in fibre core, covering provides reflecting surface and optically isolated for the transmission of light, and plays certain mechanical protection.
The tempreature bulb through optical fiber heat-shrink tube by optical fiber is needed when using optical fiber heat-shrink tube, then by fiber alignment
Position wrapped with optical fiber heat-shrink tube, when heated, optical fiber heat-shrink tube tempreature bulb fusing, tightly wrap the light after welding
Fine joint, have the function that to fill and seal；Reinforcer is played a supporting role to be acted on stretching-resisting bending-resisting；Heat-shrink tube heat shrinkable,
Fibre-optical splice, tempreature bulb and reinforcer are tightly wrapped up, form an entirety, increases the mechanical strength of fibre-optical splice part, together
When prevent moisture from invading, so as to maintain the steady in a long-term of fiber transmission performance.
In the prior art, in the engineering that fibre junction be present, there is workmen often in order to the saving fibre junction time will
Multifiber is attached by an optical fiber heat-shrink tube, and number of fibers is excessive to be placed in same optical fiber heat-shrink tube and can lead
Occur twisting, the heat-shrink tube interior phenomenon for occurring remaining bubble during pyrogenicity contracting protection between optical fiber, and be unfavorable for the maintenance in later stage；Simultaneously
Optical fiber heat-shrink tube only protects single-core fiber, is unfavorable for disk fibre, accounts for the problem of plate rail is more.
The content of the invention
The present invention is solved in the engineering that fibre junction existing for prior art be present, has workmen often in order to saving
Multifiber is attached by the fibre junction time by an optical fiber heat-shrink tube, number of fibers it is excessive be placed on same light
Occur twisting when can cause the pyrocondensation to protect in fine heat-shrink tube between optical fiber, the phenomenon of residual bubble occur in heat-shrink tube, and be unfavorable for
The maintenance in later stage；Optical fiber heat-shrink tube only protects single-core fiber simultaneously, is unfavorable for disk fibre, accounts for the problem of plate rail is more, there is provided multi-core optical
Fibre is continued the middle heat-shrink tube used, and multifiber can be connected in same thermal contraction simultaneously when it is applied, but optical fiber with
It is separated between pipeline, avoids between optical fiber and the phenomenon of twisting occur, while optical fiber is individually wrapped up using tempreature bulb, avoids heat
Occur the phenomenon of residual aeration optical fiber transmission in the draw, and be easy to related personnel to deploy later maintenance；Disk fibre side simultaneously
Just, it is few to account for plate rail, can be in the same more optical fiber of pallet disk.
The present invention is achieved through the following technical solutions：

Two grooves, second reinforcer are arranged between heat-shrinkable tube and tempreature bulb by the second groove.Tempreature bulb is uniformly distributed
In heat-shrinkable tube, the first reinforcer is arranged on the axis of heat-shrinkable tube, and the first reinforcer is provided with corresponding with tempreature bulb
Water caltrop, water caltrop and the matching grooves on tempreature bulb, the groove of each tempreature bulb are correspondingly arranged on the second groove, and the second groove is set
There is the second reinforcer of matching, the water caltrop corresponding with the first reinforcer of the second reinforcer corresponding to each tempreature bulb ensures that heat is received
Cause jointed fiber uniform force when the draw is by Thermal protection fiber junctions, avoid optical fiber because discontinuity causes showing for bending
As influenceing the communication performance of optical fiber.Multiple tempreature bulbs are set in heat-shrinkable tube can continue multifiber simultaneously, improve light
The speed that fibre continues；It turn avoid that workmen is lazy by multifiber while to be linked into a tempreature bulb simultaneously, cause light
There is the phenomenon of residual bubble in fine twisting between each other and heat-shrink tube, influence the transmission of optical fiber, be unfavorable for the maintenance workers in later stage
Work is carried out；Facilitate disk fine, reduce the occupancy of plate rail.
Further, multi-core fiber continues the middle heat-shrink tube used, and first reinforcer and the second reinforcer are stainless
One kind of steel, quartz or ceramics, the first reinforcer and the second reinforcer are made of identical material.First reinforcer is using stainless
One kind of steel, quartz or ceramics is in order to which heat-shrinkable tube ensures heated when fibre-optical splice not because the reason for expanding with heat and contract with cold
And there is the phenomenon bent.First reinforcer and the second reinforcer be made of same material be in order to ensure heat-shrinkable tube by
When hot, fibre-optical splice both sides stressing conditions are consistent, avoid fibre-optical splice from bending.
Further, multi-core fiber continues the middle heat-shrink tube used, and the groove is square, circular arc or ellipse.It is recessed
Groove may be configured as variously-shaped, can select different groove according to fibre-optical splice itself use environment, coordinate the first reinforcer keep away
Exempt from fibre-optical splice and the phenomenon bent occur.
Further, multi-core fiber continues the middle heat-shrink tube used, and second groove is identical with groove shapes.Second is recessed
It is to realize symmetrically that groove is identical with the shape of groove, preferably ensures that fibre-optical splice is in straightened condition, ensures fibre-optical splice
Transmission performance.
The present invention has the following advantages and advantages compared with the prior art：
1st, multi-core fiber of the present invention continues the middle heat-shrink tube used, sets multiple tempreature bulbs can be in heat-shrinkable tube simultaneously
Continue multifiber, improves the speed of fibre junction；It turn avoid that workmen is lazy by multifiber while to be accessed simultaneously
Into a tempreature bulb, the phenomenon for occurring residual bubble in the mutual twisting of optical fiber and heat-shrink tube is caused, influences the biography of optical fiber
Defeated, the maintenance work for being unfavorable for the later stage is carried out；Facilitate disk fine, reduce the occupancy of plate rail.
2nd, multi-core fiber of the present invention continues the middle heat-shrink tube used, and the first reinforcer is using stainless steel, quartz or ceramics
It is a kind of be in order to which heat-shrinkable tube ensures fibre-optical splice heated when not because the reason for expanding with heat and contract with cold and occur bending show
As.It is the fibre-optical splice in order to ensure heat-shrinkable tube when heated that first reinforcer and the second reinforcer are made of same material
Both sides stressing conditions are consistent, avoid fibre-optical splice from bending.
3rd, multi-core fiber of the present invention continues the middle heat-shrink tube used, and it is to realize that the second groove is identical with the shape of groove
Symmetrically, preferably ensure that fibre-optical splice is in straightened condition, ensures the transmission performance of fibre-optical splice.
