Description
Technical field
The invention belongs to the optical element field, particularly a kind of member of liquid-core optical fibre.
Background technology
Liquid-core optical fibre because have that the modular transformation coefficient is little, protecting bias can be good, to electromagnetic field, temperature field good characteristic such as be quick on the draw, it is widely used in fields such as sensing, spectral analysis, nonlinear opticses.Fill the into mixing material of test substance and water or other solvent in hollow quartz fiber inside, the refractive index of mixing material has just constituted liquid-core optical fibre greater than the refractive index (1.462) of quartz.For mixing material in the hollow quartz fiber not being trickled or evaporating, joint sealing must be used in two terminations of liquid-core optical fibre.
The joint of the existing liquid-core optical fibre close with the present invention is that a name is called the Chinese patent of " end socket of liquid-core optical fibre and preparation method thereof ", publication number CN 1064551A, open day on September 16th, 1992.The structure of the end socket of disclosed liquid-core optical fibre is referring to Fig. 1.The blind end of glass tube 2 is a window 1, and openend is used to insert hollow quartz fiber 5, and the centre of glass tube 2 is blow molded into fluid storage compartment 3, and liquid injection hole 4 is arranged on the fluid storage compartment 3.The termination of hollow quartz fiber 5 arrives window 1 by fluid storage compartment 3 in end socket.The openend of glass tube 2 makes hollow silica fibre 5 fix and be closed in the glass tube 2 to easy the to be molten metal 6 between the fluid storage compartment 3, again with fluid sealant 7 sealings.
During use, will be before the fluid injection easy molten metal 6 sealings of hollow silica fibre 5 usefulness, hollow silica fibre 5 is fixing, and this method is difficult to make hollow silica fibre 5 to be fixed on the axis of glass tube 2, influences the conduction of light; To cause the inconvenience of use with burning the opening of sealing liquid injection hole 4 after the fluid injection; Irritate fluid sealant 7 again owing to solidify with easy molten metal 6 between hollow silica fibre 5 and the end socket, this end socket can only disposablely be used, can not reuse.
Summary of the invention
The technical problem to be solved in the present invention is to overcome disadvantages of background technology, designs the sealing adaptor that a kind of easy to use, hollow silica fibre can be easy to be contained on the glass tube axis, can reusable liquid-core optical fibre.
Liquid core optical fiber sealing joint of the present invention, by glass tube 2, the window 1 of glass tube 2 blind ends, blown fluid storage compartment 3 in the middle of the glass tube 2, liquid injection hole 4 is arranged on the fluid storage compartment 3, and the liquid injection hole end socket seat 10, liquid injection hole rubber cushion 9, the liquid injection hole end socket lid 8 that are installed in liquid injection hole 4 opening parts, the fibre-optical splice seat 11, optical fiber seal rubber cushion 12, the fibre-optical splice lid 13 that are installed in glass tube 2 openends constitute;
Liquid injection hole end socket seat 10 is columnar members, and the medial surface gluing of cylinder and liquid injection hole 4 outsides are adhesively fixed, and the upper bottom surface perforate is used for fluid injection, and there is screw thread in liquid injection hole end socket seat 10 outsides; Liquid injection hole end socket lid 8 is cylinders of another bottom surface sealing of a bottom surface opening, and there are screw thread and the engagement of liquid injection hole end socket seat 10 external threads in its inboard; The liquid injection hole rubber cushion 9 of disc is placed on liquid injection hole end socket seat 10 upper bottom surfaces and the liquid injection hole end socket covers between the inboard, 8 bottom surface;
Fibre-optical splice seat 11 is that the longitudinal section is I-shaped cylinder, and lateral surface has screw thread, and the medial surface gluing and the glass tube 2 openends outside are adhesively fixed, and tabula 14 centers in the middle of cylinder have circular hole, and the circular hole size can be passed hollow silica fibre 5; Optical fiber seal rubber cushion 12 is columniform, has slotted hole 15 along central axis and can pass hollow silica fibre 5, and the external diameter of cylinder and fibre-optical splice seat 11 internal diameters match; Fibre-optical splice lid 13 is columniform, open the coaxial circular hole of stairstepping in it, the diameter of the big hole 16 of one end is corresponding with fibre-optical splice seat 11 external diameters, internal thread that has and the engagement of fibre-optical splice seat 11 external threads, the diameter and fibre-optical splice seat 11 internal diameters of middle middle circular hole 17 match, and the diameter of the small sircle hole 18 of outer end can pass hollow silica fibre 5.
Tabula 14 in the fibre-optical splice seat 11 contacts a side with optical fiber seal rubber cushion 12 the wedge type lead angle; Middle circular hole 17 in the fibre-optical splice lid 13 contacts a side with optical fiber seal rubber cushion 12 terminations the wedge type lead angle.Preferably 45 ° of wedge type lead angles.
When liquid core optical fiber sealing joint is installed, at first that glass tube openend and fibre-optical splice seat is glued together with AB, fibre-optical splice lid and optical fiber seal rubber cushion are enclosed within on the hollow quartz fiber, again hollow quartz fiber being had circular hole along the tabula center of fibre-optical splice seat is inserted in the fluid storage compartment, arrive window until hollow quartz fiber, screw the fibre-optical splice lid then.Tighten in the process of fibre-optical splice lid, because fibre-optical splice seat and the special inner structure that cooperatively interacts of fibre-optical splice lid, make the radial force compression of optical fiber seal rubber cushion, hollow quartz fiber is fixed on the axial line of fibre-optical splice, simultaneously, also played the effect of sealing, made the liquid of fluid storage compartment be unlikely to outflow.
Secondly, liquid injection hole 4 and liquid injection hole end socket seat is glued together with AB; The mixing material that will contain test substance injects fluid storage compartment by the perforate of liquid injection hole end socket seat upper bottom surface, and then is full of hollow quartz fiber.
At last fill up the liquid injection hole rubber cushion in the perforate of liquid injection hole end socket seat upper bottom surface, refilling and screw liquid chamber end socket lid can use.Because the liquid injection hole rubber cushion is pressed in the perforate of liquid injection hole end socket seat upper bottom surface, make the liquid of fluid storage compartment be unlikely to outflow.
From the structure of liquid core optical fiber sealing joint of the present invention as can be seen, liquid core optical fiber sealing joint good seal performance of the present invention; Just can make hollow quartz fiber along glass tube central axis alignment windows as long as install, can deflection; Easy to install, just suit gets final product with screwing, without naked light envelope liquid injection hole; Can reuse.
