Embodiment
To do further to specify to embodiment of the present invention below in conjunction with accompanying drawing.
See also Fig. 1, be the optical fiber coupled connector 10 of embodiment of the present invention first embodiment.This optical fiber coupled connector 10 comprises a body 12 and two optical fiber 14.
See also Fig. 4, each optical fiber 14 comprises a bare fibre 142, a clad 144 and an optical lens 146.This bare fibre 142 is used for the transmission optics signal.This bare fibre 142 comprises the first relative end 141 and second end 143.This clad 144 be coated on this first end 141 around.This optical lens 146 comprises a round platform portion 147 and a sphere portion 148.This round platform portion 147 extends from the length direction of this bare fibre 142 of end face upper edge of this second end 143; This sphere portion 148 extends from the length direction of this round platform portion this bare fibre 142 of 147 upper edges, and this round platform portion 147 is between the end face and this sphere portion 148 of this second end 143.In this embodiment, this bare fibre 142 and this optical lens 146 are processed by quartz material, and each optical fiber 14 all makes through chemical method for etching.
Please consult Fig. 2 and Fig. 3 in the lump, this body 12 comprises the roof 120 and the diapire 121 of opposing parallel, the parallel relative the first side wall 122 and second sidewall 123, and parallel relative the 3rd sidewall 124 and the 4th sidewall 125.This first side wall 122, the 3rd sidewall 124, this second sidewall 123 and the 4th sidewall 125 be vertical connection successively.This first side wall 122, the 3rd sidewall 124, this second sidewall 123 and the 4th sidewall 125 vertical this roof 120 and this diapires 121 of connecting.
This body 12 offers two receiving spaces 126 of accommodating these two optical fiber 14, and each receiving space 126 all runs through this first side wall 122 and the 3rd sidewall 124.Each receiving space 126 includes one first section of accommodating 126a, second section of an accommodating 126b and one the 3rd section of accommodating 126c.This second section of accommodating 126b connects this first section of accommodating 126a and the 3rd section of accommodating 126c and is communicated with this first section of accommodating 126a and the 3rd section of accommodating 126c.This first section of accommodating 126a partly accommodates this clad 144; This second section of accommodating 126b accommodates this bare fibre 142; The shape of the 3rd section of accommodating 126c is that the round platform of hollow is to match with this round platform portion 147; This round platform portion 147 is sticked in the 3rd section of the accommodating 126c, and these sphere portion 148 relative these the first side walls 122 are outstanding.
When using these optical fiber coupled connector 10 transmitting optical signals, if this optical fiber coupled connector 10 is during as the light signal transmitting terminal, the light that bare fibre 142 sends directly gets into optical lens 146, penetrates from optical lens 146 again; If this optical fiber coupled connector 10 is during as the light signal receiving end, light gets into from optical lens 146, directly arrives bare fibre 142 from optical lens 146 again.No matter optical fiber coupled connector 10 is as the optical signal transmitting end, still as the receiving end of light signal, all avoids being provided with a medium between bare fibre 142 and the optical lens 146 more, and therefore, reduce at the ray refraction interface, thereby promotes the transfer efficiency of light signal.
