Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention being done to one specifically introduces.
Refer to Fig. 1 and Fig. 2, the joints of optical fibre 100 of embodiment of the present invention are directed into optical fiber (not shown) for the light signal that optical signal launcher (not shown) is launched.The described joints of optical fibre 100 comprise the second end 20 that a first end 10 and and described first end 10 are opposing.Described first end 10 is for connecting described optical fiber, and described the second end 20 is for connecting described optical signal launcher.
Described first end 10 offers a fiber optic hub 11 extending to described the second end 20.Described fiber optic hub 11 is for accommodating and fix one end of described optical fiber.
Described the second end 20 offers a groove 21 extending to described first end 10.Described groove 21 is for accommodating described optical signal launcher.Described groove 21 has a bottom surface 211.Described bottom surface 211 offers a blind hole 212 caving in to described first end 10.Described blind hole has a coupled lens 30 on 212 bottom surfaces.In present embodiment, described coupled lens 30 is non-spherical lens.The periphery of described coupled lens 30 is connected to the madial wall of described blind hole 212, and in other words, the peripheral shape of described coupled lens 30 and size correspond respectively to shape and the size of described blind hole 212 xsects.In the time carrying out concentricity measurement, measurement instrument can capture the edge of described blind hole 212 madial walls as described coupled lens 30.On the end face of described the second end 20, be also formed with two draw-in grooves 22 that cave in to described first end 10, described draw-in groove 22, for fastening with described optical signal launcher, prevents described optical signal launcher rotating relative to the described joints of optical fibre.In present embodiment, described draw-in groove 22 is arch, and the arcuate surface of draw-in groove 22 can increase the degree of stability of engaging.The quantity of described draw-in groove 22 is not limited to two, can do suitable change according to reality.
In use, the end of optical fiber accommodated and be fixed in described fiber optic hub 11, optical signal launcher being arranged to the second end 20 of the described joints of optical fibre, the light signal transmit direction of described optical signal launcher is towards described coupled lens 30.Described optical signal launcher, the described joints of optical fibre 100 and described optical fiber form one can transmitting optical signal light signal transmission device.In present embodiment, described optical signal launcher is laser diode (laser diode).The light signal of described optical signal launcher transmitting imports described optical fiber by described coupled lens 30, realizes the output of light signal.
The described joints of optical fibre 100 adopt ejection shaping die to make, because described coupled lens 30 is arranged in the blind hole 212 with cross section taken in correspondence shape and size, described blind hole 212 madial walls can be crawled as described coupled lens 30 edges in the time measuring, therefore in the time of ejection formation, even if moulding material causes the joints of optical fibre 100 corners to occur irregular depression because the high coefficient of viscosity cannot fill up mould corner, do not affect the measurement of the described joints of optical fibre 100 yet.Therefore, the described joints of optical fibre 100 can conveniently be measured and can guarantee the accuracy of measuring.
