Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
See also Fig. 1, the present invention's one most preferred embodiment provides the optical fiber coupled connector 20 of the optical fiber 24 that is used to be of coupled connections, and it comprises body 22.
See also Fig. 2 and Fig. 3, body 22 has first end 221 and and described first end 221 opposite second end 222.Described first end 221 is provided with optical lens 226, and described the second end 222 offers accepting hole 228, and described accepting hole 228 extends and towards described optical lens 226 to described first end 221 from described the second end 222.
The light exit side of optical fiber 24 inserts in the described accepting hole 228, make described optical fiber 24 be contained in described accepting hole 228, and the light exit side of described optical fiber 24 is towards described optical lens 226.The light exit side of described optical fiber 24 is connected with described body 22 in described accepting hole 228 by glue 26.The refractive index of described glue 26 is close or identical with the refractive index of described body 22, thus, can reduce the refractive index difference between described glue 26 and the described body 22.
Preferably, the refractive index of described glue 26 is identical with the refractive index of described body 22.Thus, in the time of can avoiding the light signal of optical fiber 24 transmission between the medium of two kinds of different refractivities, to transmit, because of producing the energy loss that refraction causes light signal, particularly when the refractive index between medium differs greatly.Certainly, be understandable that the refractive index of the refractive index of glue 26 and body 22 is close promptly to differ hour, because the refraction that produces is less, then can reduce the loss of the energy of the light signal that causes because of refraction.In the present embodiment, the refractive index n of described body 22, the ranges of indices of refraction of described glue is 0.9n～1.1n.
In the present embodiment, the light exit side structure of optical fiber 24 is that example describes with stepped three layers, and innermost layer is the fibre core with covering, and the middle layer is a coat, and outermost layer is a sheath.
Preferably, accepting hole 228 is a staircase structure, matches with the light exit side structure of optical fiber 24, is convenient to body 22 global formations simultaneously, especially is convenient to the withdrawing pattern that die is gone into son.
The material of described optical lens 226 is identical with the material of body 22.The focus of described optical lens 226 is positioned on the extension line of described accepting hole 228, and the focus of described optical lens 226 is between the light exit side and described optical lens 226 of described optical fiber 24.
