Description
Affiliated field
The hermetically-sealed construction of liquid-core optical fibre relates to the butt-end packing of liquid-core optical fibre, relates in particular to the butt-end packing of making the liquid-core optical fibre of termination encapsulant with the hard structure body.
Background technology
Liquid-core optical fibre is a kind of optical waveguide of new structure, and it adopts fluent material is that inside of optical fibre passes photosphere, and macromolecule polymer material is made the optics cortex, and butt-end packing is carried out with the hard column with certain-length in two ends.Because core, the cladding range of choice of liquid-core optical fibre are bigger, can adopt different core/claddings to be complementary at different transmission wavelength requirements, are easy to prepare the high-power biography optical element of big core diameter, large-numerical aperture.The core of this optical fiber is to be filled by liquid, and the filling rate of its gross section is 100%, the not high optical transmission loss that causes of filling rate in the time of can avoiding solid phases such as glass or quartz to pass in the light beams because of the monofilament boundling.Overcome fully the solid phase core pass that light beam often has, cause serious day by day fracture of wire and pass degradation fatal shortcoming under the optical efficiency because of alternating bending, it is simple to add its manufacturing process, cost of manufacture is cheap, in the light transmission of particular range of wavelengths is used, premium properties (for example at the ultraviolet light wave band) is arranged, liquid-core optical fibre is as a kind of novel biography light medium, and it is irreplaceable that its above-mentioned advantage is that traditional solid phase passes light beam.But, be unbodied liquid just because of the core in its cortex, its butt-end packing technology seems most important, because the quality of its butt-end packing technology directly influences the quality and the serviceable life of product.Common solid phase optical fiber passes the butt-end packing of light beam, is to carry out with the method for thermal treatment or mechanical compaction.Because the adhesion between high molecular cortical material and the hard structure material is relatively poor, does not spill so heat treatment method can not guarantee the liquid core material of inside of optical fibre usually.And in the prior art, two kinds of practical hermetically-sealed constructions are arranged: first kind of structure as shown in Figure 1, it typically uses two-section metalwork 6, the rubber ring 7 that extruding is clipped in the middle by two metalworks, 6 interference fit, is pressed on cortex 2 on the hard quartz construction 1.As time goes on, the creep of elastomeric material itself, aging will cause the decline of snap-in force, and leakage takes place.Especially as the speciality of liquid-core optical fibre, be particularly suitable for transmitting ultraviolet light, rubber wears out and more quickens under ultraviolet irradiation.Secondly, for the enhanced leaktightness effect, two metals of interference fit all need to increase thickness, have so just increased the external diameter of optical fiber, make it be difficult to match with the little tool interface system of size.Second kind of hermetically-sealed construction as shown in Figure 2, the method that its adopts module to compress packs tightly optic fibre end with a plurality of modules from a plurality of directions, and the covering flexible pipe is pressed on the hard optical window 1.This compressing structure behind the module matched moulds, can form the slit, and the liquid core material can be oozed out from the slit sometimes, and its sealing property can not get guaranteeing.
Summary of the invention
At the defective of above-mentioned existence, the utility model proposes a kind of hermetically-sealed construction of novel liquid-core optical fibre, it can guarantee the sealing property of liquid-core optical fibre, improves the serviceable life of optical fiber and widens its range of application.
It comprises hard optical window body 1, optical fiber cortex 2, liquid sandwich layer 3, it is characterized in that: be wrapped with metal-coating 4 at hard structure body 1, on metal-coating 4 surfaces annular compressed grooves 5 arranged.This groove 5 can be together, also can be multiple tracks.Metal-coating 4 material therefors can be metals such as stainless steel, copper and aluminium.Power can not be too big during compacting, dark excessively compressed grooves meeting mechanical damage hard structure; Power during compacting can not be too little, and enough big snap-in force is the condition precedent that guarantees excellent sealing effect.Because metalwork overcoat 4 at normal temperatures can creep, aging, can reduce the generation of the phenomenon of leakage of liquid-core optical fibre effectively, keep the long-term usability of liquid-core optical fibre.Multiple tracks compresses reinforcing, has further guaranteed the raising of sealing property.Simple in structure, the handling ease of hermetically-sealed construction that adopts the utility model scheme to make simultaneously, good sealing effect, long service life has reduced the size of compressing structure effectively, has increased the popularity that liquid-core optical fibre is used.

Embodiment
In cortex 2 flexible pipes, inject liquid core material 3, seal as hard structure body 1 with columniform quartz at the two ends of cortex 2 flexible pipes and stop up.Be with the stainless steel pipe box 4 of thin-walled outside quartz construction body 1, seal with the pressing machinery device that has the hard edge, sealing part has two road compressed grooves 5.
