Embodiment
Referring to Fig. 1 to Fig. 8, the utility model comprises main fiber (1), branch optical fiber (2), sliding shoe (3) and pedestal (4), and sliding shoe (3) is slidingly matched with pedestal (4); Semicolumn groove (9) is arranged on the level that is slidingly matched of pedestal (4), there is fixedly main fiber (1) of a vertical cylinder hole (10) inserting at this groove (9) middle part, main fiber (1) inner face is semicolumn groove (5), described groove (5) flushes with the groove (9) of pedestal (4), and coincide sliding joining with branch optical fiber (2) face of cylinder; There is semi-cylindrical recesses (7) to fixedly connected on the surface level that is slidingly matched of sliding shoe (3) with branch optical fiber (2) face of cylinder coupling; Be positioned at main fiber (1) inner face top, V-notch (12) is coated with high reflective metal film layer (6) in branch optical fiber (2) cylinder.It is 1mm step-refraction index distribution plastic optical fiber that main fiber, branch optical fiber all adopt core diameter.
At an end of vertical main fiber (1), at the vertical fiber axis direction, scribe a semi-cylindrical recesses mouth (5), the same main fiber of the diameter of its cylinder, the radius of the same main fiber of groove (5) degree of depth (1).Carve a V-notch (12) at the branch middle part, kerf angle is 90 degree, the diameter of the same branch optical fiber of its degree of depth (2); At the fiber end face plating high reflecting metal film (6) of V-notch (12), adopt the V-notch (12) on the polymkeric substance filling branch optical fiber (2) at last then, be returned to the optical fiber original state.
Adopt the metal or the polymer manufacture sliding shoe (3) of rectangle, sliding shoe (3) edge adopts sphenocephaly (8) structure.The semi-cylindrical recesses (7) that radius ratio optical fiber is slightly a little bigger is carved on plane along sliding shoe (3).Adopt the metal or the polymer manufacture pedestal (4) of rectangle, wedge-shaped impression (11) structure that pedestal (4) adopts sphenocephaly (8) structure of sliding shoe (3) to coincide.The semi-cylindrical recesses (9) of carving a same branch optical fiber of radius (2) on the plane of pedestal (4) at this groove (9) middle part, along the direction of perpendicular grooves (9), is offered the cylindrical hole (10) of a same main fiber of radius (1).
To the assembling of coupling mechanism, adopt following steps:
1) branch optical fiber (2) is embedded groove (8), the plated film face (6) on the branch optical fiber (2) should be fixed on branch optical fiber (2) on the sliding shoe (3) with glue over against sliding shoe (3) plane.
2) main fiber (1) is gone up cylindrical hole (10) by pedestal (4) and is inserted pedestal (4), allows the semi-cylindrical recesses (5) on the main fiber (1) coincide with the semi-cylindrical recesses (9) of pedestal (4), uses glue that main fiber (1) is fixed on the pedestal (4) at last.
