In view of this, the utility model aims to provide a kind of fan-shaped stainless steel tube optical unit.
In order to realize the purpose of this utility model, the utility model provides a kind of fan-shaped stainless steel tube optical unit, it comprises fan-shaped stainless-steel tube and is arranged at the optical fiber in described fan-shaped stainless-steel tube, and in described fan-shaped stainless-steel tube, be filled with ointment, described ointment is overlying on described optical fibre packages wherein.
Preferably, in described fan-shaped stainless-steel tube, be provided with a plurality of optical fiber, described a plurality of optical fiber interval arranges.
Preferably, in described fan-shaped stainless-steel tube, be provided with a plurality of optical fiber, described a plurality of optical fiber is stranded mutually.
The fan-shaped stainless steel tube optical unit that the utility model embodiment provides has enriched the shape of stainless steel tube optical unit to be selected, and adopts the cable of this fan-shaped stainless steel tube optical unit to have advantages of that same sectional area condition downloading flow is large.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the fan-shaped stainless steel tube optical unit that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model embodiment provides a kind of fan-shaped stainless steel tube optical unit, and this fan-shaped stainless steel tube optical unit can be used in Optical Fiber composite overhead Ground Wire, optical phase conductor, for carrying out communication.
Please refer to Fig. 1, this fan-shaped stainless steel tube optical unit comprises fan-shaped stainless-steel tube 1 and is arranged at the optical fiber 2 in fan-shaped stainless-steel tube, and in fan-shaped stainless-steel tube 1, be filled with ointment 3, ointment 3 is coated on optical fiber 2 wherein, to protect optical fiber 2 injury-free.In the present embodiment, in fan-shaped stainless-steel tube 1, be provided with a plurality of optical fiber 2.It should be noted that, indication " fan-shaped ", not defined fan-shaped on geometric meaning herein, and refer to that the xsect of stainless-steel tube is roughly covering of the fan shape.
In a preferred embodiment, in fan-shaped stainless-steel tube 1, be provided with a plurality of optical fiber 2, and the plurality of optical fiber 2 intervals arrange, can strengthen thus the ability to communicate of cable.
In another preferred embodiment, in fan-shaped stainless-steel tube 1, be provided with a plurality of optical fiber 2, and the plurality of optical fiber 2 is stranded mutually.
The manufacture method of this fan-shaped stainless steel tube optical unit comprises the steps:
Step a: stainless steel band is cut into and has required width; In the present embodiment, the stainless steel band of 0.15mm～0.4mm thickness is discarded to steel band trimming device from actinobacillus device, steel band trimming device is according to default required stainless steel band width, by the unnecessary Partial Resection of stainless steel band, and guarantee the consistance of stainless steel band width and the homogeneity of stainless steel band burr after stainless steel band trimming;
Step b: by the curling rounded tubulose of stainless steel band; In the curling process of stainless steel band, guarantee that stainless steel band is curling stablely not rock, between the dual-side of curling rear stainless steel band, leave the gap of even width 0.1mm left and right, and gap is upward;
Step c: weld in the gap to stainless steel band, makes stainless steel band form stainless-steel tube;
Steps d: use fan-shaped mould that stainless-steel tube is shaped to fan-shaped, form fan-shaped stainless-steel tube 1; Former is generally also furnished with lubricating system, in forming process, is lubricated;
Step e: optical fiber 2 and ointment 3 are imported in stainless-steel tube, form fan-shaped stainless steel tube optical unit.
In a preferred embodiment, steps d and step c carry out simultaneously, also use fan-shaped mould that the step of the step of stainless-steel tube moulding and soldering stainless steel band is carried out simultaneously.It should be noted that, because stainless steel band is very long, therefore welding is carried out continuously, and indication carries out simultaneously herein, refers in the process that is soldered front end and continues to weld backward, can to front end, carry out moulding simultaneously.
In a preferred embodiment, step e and step c carry out simultaneously, are also about to optical fiber and ointment and import in stainless-steel tube and carry out with the step of soldering stainless steel band simultaneously.It should be noted that, because stainless steel band is very long, therefore welding is carried out continuously, and indication carries out simultaneously herein, can refer in the process that is soldered front end and continues to weld backward, imports optical fiber and ointment in the stainless-steel tube of forward end simultaneously.
Step c, steps d, tri-steps of step e also can be carried out simultaneously.Similarly, as mentioned above, because welding, moulding, importing optical fiber etc. are all continuous processes, therefore indication carries out simultaneously herein, not refer to three's Complete Synchronization in time, and refer to that these three steps have lap in time, but can have a less mistiming.
In a preferred embodiment, in step c, during welding, adopt argon shield, so that weld seam is not oxidized in welding process.
In a preferred embodiment, in step c, use laser or plasma to carry out continuous welding to the gap of stainless steel band.
In a preferred embodiment, in step e, the boot speed of optical fiber is identical with the drawing speed of stainless-steel tube, to guarantee that optical fiber 2 is not subject to pulling force in fan-shaped stainless-steel tube, thereby the quality of fan-shaped stainless steel tube optical unit is guaranteed.
In a preferred embodiment, in step b, use the curling mould of gradual change type by stainless steel band brake forming, the curling mould of this gradual change type can be the curling mould of active gradual change type, also can be the curling mould of passive gradual change type, by the curling mould of gradual change type, stainless steel band is slowly curled into circle.
The fan-shaped stainless steel tube optical unit that the utility model embodiment provides has enriched the shape of stainless steel tube optical unit to be selected, and adopts the cable of this fan-shaped stainless steel tube optical unit to have advantages of that same sectional area condition downloading flow is large.The manufacture method of the fan-shaped stainless steel tube optical unit that the utility model embodiment provides, its technique is fairly simple, and the quality of the fan-shaped stainless steel tube optical unit of producing is also better.
