Problems solved by technology

[0004] During use, the hollow silica fiber 5 should be sealed with soluble metal 6 before liquid injection, and the hollow silica fiber 5 is fixed. This method is difficult to fix the hollow silica fiber 5 on the central axis of the glass tube 2, which affects Conduction of light; after liquid injection, it is necessary to use fire to seal the opening of the liquid injection hole 4, which is inconvenient to use; because the soluble metal 6 is used to solidify and then fill the sealant 7 between the hollow-core quartz optical fiber 5 and the head, so that The head can only be used once and cannot be reused

Embodiment 1

[0020] Example 1 Overall structure of the present invention

[0021] see figure 2 , 1 is a window; 2 is a glass tube; window 1 is at the closed end of the glass tube 2; the middle of the glass tube 2 is blown into a liquid storage chamber 3; the liquid storage chamber 3 has a liquid injection hole 4. The above-mentioned components are the same parts as the background technology. They are made of glass and can be blown into a "three-way" shape from a glass tube to form a whole. The intersection of the three-way is the liquid storage chamber 3; 5 is hollow quartz optical fiber.

[0022] 10 is the injection hole head seat, which is bonded to the open end of the injection hole 4 by AB glue, and the upper bottom surface is open for injection; 9 is the injection hole rubber pad, which is in the shape of a disc; 8 is the injection hole The liquid hole head cover has a thread on its inner side to engage with the external thread of the liquid hole head seat 10, which can be screwed in and ...

Embodiment 2

[0024] Embodiment 2 The structure of the optical fiber connector seat, the optical fiber sealing rubber gasket, and the optical fiber connector cover

[0025] The shape of the optical fiber connector base 11 is shown in FIG. 3. The optical fiber connector base 11 is a cylinder with an I-shaped longitudinal section, with ribs on the outer side. The inner cylinder of the optical fiber connector base 11 is divided into two parts by a diaphragm 14 in the middle. A circular hole is opened in the center of the diaphragm 14 and the size of the circular hole is Just pass through the hollow-core silica optical fiber 5.

[0026] The shape of the optical fiber sealing rubber gasket 12 is shown in FIG. 4. The optical fiber sealing rubber gasket 12 is cylindrical, and a long hole 15 is opened along the central axis. The diameter of the long hole 15 can pass through the hollow-core silica optical fiber 5; the outer diameter of the optical fiber sealing rubber gasket 12 matches the inner diamete...

Description

Technical field [0001] The invention belongs to the field of optical components, and particularly relates to a component of a liquid core optical fiber. Background technique [0002] Because of its excellent characteristics such as low mode conversion coefficient, good polarization-maintaining performance, and sensitive response to electromagnetic fields and temperature fields, the liquid core fiber has a wide range of applications in the fields of sensing, spectral analysis, and nonlinear optics. The hollow silica fiber is filled with a mixed liquid of the substance to be measured and water or other solvents. The refractive index of the mixed liquid is greater than that of quartz (1.462), which constitutes a liquid core fiber. In order to prevent the mixed liquid in the hollow silica optical fiber from flowing or evaporating, the two ends of the liquid core optical fiber must be sealed with joints. [0003] The existing liquid core optical fiber connector similar to the present ...
