Description
Technical field:
The present invention relates to a kind of ultra-thin pyrocondensation belt fastening cable configuration and production method.
Background technology:
In the mode of traditional fixed layer-twisted type cable core structure of being hanked tie using yarn, hot retraction can be produced because conventional yarn is heated,
And high temperature can increase the activity of high polymer material internal structure simultaneously, make the Loose tube material of secondary coating macromolecule lining material
Soften, stabbed appearance Le trace so as to frequently result in Loose tube in optical cable, make optic fibre force, influence properties of optical fiber cable and using the longevity
Life.
The content of the invention:
The present invention provides one kind using ultra-thin pyrocondensation belt around cable core surface is wrapped in, and then ultra-thin pyrocondensation belt is heated, and makes
Means of heat-shrinkable film shrinks fastening cable core structure, be then coated to armor and outer jacket again, complete pyrocondensation belt fastening cable configuration and
Production method.
The technical solution adopted in the present invention has:A kind of ultra-thin pyrocondensation belt fastening cable configuration, including center reinforcemen, light
Fine, Loose tube and PE sheaths, the center reinforcemen and some Loose tubes are twisted and form cable core, and optical fiber is arranged in Loose tube
Interior, PE sheaths are wrapped in the outer surface of cable core, in addition to ultra-thin pyrocondensation belt and armor, the ultra-thin pyrocondensation belt and armor by
It is interior to being wrapped in successively on cable core outside.
Further, the ultra-thin pyrocondensation belt is made of PET means of heat-shrinkable film materials.
Further, armor is formed using steel band or aluminium strip winding.
Further, it is equipped with tear rope in the PE sheaths.
For ease of producing above-mentioned cable configuration, the present invention provides a kind of producer of ultra-thin pyrocondensation belt fastening cable configuration
Method, including the making step of Loose tube and comprising center reinforcemen and some Loose tubes are carried out into the twisted cable for forming cable core
Core making step, the center reinforcemen are twisted with Loose tube and form the ultra-thin pyrocondensation belt of winding after cable core, ultra-thin pyrocondensation belt parcel
Heated after cable core, banding cable core after ultra-thin pyrocondensation belt heat shrinkable, winding steel band and form armor on ultra-thin pyrocondensation belt, most
Extruding machine extrusion moulding PE sheaths and armor is wrapped up afterwards, ultimately form optical cable.
Further, the temperature heated after the ultra-thin pyrocondensation belt parcel cable core is 120 DEG C -180 DEG C.
Further, the time heated after the ultra-thin pyrocondensation belt parcel cable core is -10 seconds 5 seconds.
The present invention has the advantages that:
1)Direct wrapped ultra-thin pyrocondensation belt after Loose tube is twisted in the present invention, banding cable core after pyrocondensation belt heat shrinkable, reaches tight
Gu the effect of cable configuration, due to instead of prick yarn fastening means, just solve yarn hank tie occur prick trace process difficulties;
2)It is big around the pyrocondensation belt and cable core contact surface for being wrapped in cable core surface, the frictional force of cable core internal structure is added, hinders cable
Core structure change caused by extraneous factor changes, therefore the structure of optical cable can more be stablized, and then substantially improve optical cable
Temperature performance and mechanical performance;
3)The optical cable hanked tie using bundle yarn reprocesses difficulty, and the bundle yarn of especially releasing cable core is more cumbersome, the efficiency reprocessed at present
It is extremely low, thus optical cable often because the exception of some processes cause product inventory overstock can not Repair, and light of the present invention
Cable structure only needs to increase a tear rope inside pyrocondensation belt, directly tears pyrocondensation belt, armor and the sheath of outside, internal
Cable core structure, which becomes, to scatter, and can directly carry out Repair, greatly reduce the cost of optical cable exception stock.
Brief description of the drawings:
Fig. 1 is the structure chart that the ultra-thin pyrocondensation belt of the present invention fastens cable configuration.
Embodiment:
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of ultra-thin pyrocondensation belt fastening cable configuration of the present invention, including center reinforcemen 1, optical fiber 2, pine set
Pipe 3, ultra-thin pyrocondensation belt 5, armor 6 and PE sheaths 7, center reinforcemen 1 and some Loose tubes 3 are twisted and form cable core 10, light
Fibre 2 is arranged in Loose tube 3, and PE sheaths 7 are wrapped in the outer surface of cable core 10, ultra-thin pyrocondensation belt 5 and armor 6 from the inside to the outside according to
It is secondary to be wrapped on cable core 10.
Ultra-thin pyrocondensation belt 5 in the present invention is made of PET means of heat-shrinkable film materials;Armor 6 using steel band or aluminium strip around
If form.Armor 6 is increasing the intensity of optical cable.
Tear rope 4 is equipped with PE sheaths 7, the ultra-thin pyrocondensation belt 5 and armouring of outside can be directly torn by tear rope 4
Layer 6, internal cable core structure, which becomes, to scatter, and can directly carry out Repair, greatly reduce the cost of optical cable exception stock.
It is big around the ultra-thin pyrocondensation belt 5 and the contact surface of cable core 10 for being wrapped in the surface of cable core 10, add the internal structure of cable core 10
Frictional force, the structure change caused by extraneous factor changes of cable core 10 is hindered, therefore the structure of optical cable can more be stablized, and then
Substantially improve the temperature performance and mechanical performance of optical cable.
For ease of producing ultra-thin pyrocondensation belt fastening optical cable, the present invention provides a kind of life of ultra-thin pyrocondensation belt fastening cable configuration
Production method, including the making step of Loose tube and comprising carrying out center reinforcemen and some Loose tubes twisted to form cable core
Cable core making step(Two step is same as the prior art, therefore repeats no more), it is twisted in center reinforcemen 1 and Loose tube 3
The ultra-thin pyrocondensation belt 5 of winding after formation cable core 10, ultra-thin pyrocondensation belt 5 are heated after wrapping up cable core 10, heating-up temperature 120
DEG C -180 DEG C, the heat time is -10 seconds 5 seconds.Banding cable core 10 after the ultra-thin heat shrinkable of pyrocondensation belt 5, on ultra-thin pyrocondensation belt 5 around
If steel band simultaneously forms armor 6, last extruding machine extrusion moulding PE sheaths 7 simultaneously wrap up armor, ultimately form optical cable.
Direct wrapped ultra-thin pyrocondensation belt 5 after Loose tube 3 is twisted, banding cable core after pyrocondensation belt heat shrinkable, reaches fastening light
The effect of cable structure, due to instead of prick yarn fastening means, just solve yarn hank tie occur prick trace process difficulties.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
