Fibre 102 and glue 103,101 internal diameter of ceramic capillary are more bigger than 102 cladding diameter of optical fiber, penetrate optical fiber in ceramic capillary 101
102 blend compounds 103 are fixed.Glue 103 is more than in 101 tail portion of ceramic capillary, and glue 103 penetrates into and runs through ceramic capillary 101
Internal whole length, glue 103 fill the gap between full optical fiber 102 and ceramic capillary 101 and are heating and curing, ceramic capillary
The end face of the corresponding docking of pipe 101, optical fiber 102 and glue 103 is ground and polished respectively.Optical fiber ceramic lock pin 2 includes ceramic capillary
Pipe 104, optical fiber 105 and glue 106, construction and optical fiber ceramic lock pin 1 are identical.
Two optical fiber ceramic lock pin docking are inserted in porcelain bushing 107, in order to ensure lesser junction loss, two optical fiber
The fiber end face of ceramic insertion core needs to be in close contact.In actual use, optical fiber ceramic lock pin 1 and optical fiber ceramic lock pin 2 can
Often plug docking can be needed, the optics end face that often will lead to optical fiber ceramic lock pin inner fiber generates various damage defects, from
And the access times of the optical fiber connector are influenced, cause to be used for a long time.
As shown in Fig. 2, two schematic diagram of conventional fiber optic connectors example structure, structure is similar to figure one, uniquely not
It is both that two optical fiber ceramic lock pin end faces have been ground into oblique angle, can further improve the return loss of optical fiber connector in this way.But
It is in close contact since the use of the connector optical fiber ceramic core is also required to fiber end face, equally exists the wind that fiber end face is damaged
Danger, so the optical fiber connector of the structure can not be used for a long time.
As shown in figure 3, the invention discloses the optical fiber connectors that one kind can plug for a long time comprising two optical fiber ceramics are inserted
Core (optical fiber ceramic lock pin 1 and optical fiber ceramic lock pin 2) and porcelain bushing 307, two optical fiber ceramic lock pins dock and are inserted in ceramics
Casing 307,
Optical fiber ceramic lock pin 2 includes two optical fiber ceramic lock pin porcelain bushings, and optical fiber ceramic lock pin includes ceramic capillary, optical fiber
And lenticule, the internal diameter of ceramic capillary are greater than the cladding diameter of optical fiber, optical fiber is arranged in ceramic capillary, ceramic capillary
Docking end face be equipped with recessed from outside to inside first step and second step, lenticule is adhered on second step, lenticule
Front end face be lower than first step, first step of the ceramic capillary of two optical fiber ceramic lock pins contacts docking,
Gap filling has glue between the optical fiber and the inner wall of ceramic capillary, and the glue is heating and curing.
The face of the optical fiber is with polishing oblique angle structure.
Optical fiber ceramic lock pin 1 includes ceramic capillary 301, optical fiber 302, glue 303 and lenticule 308, ceramic capillary 301
