Specific embodiment
Also referring to the photoelectric conversion module 100 that Fig. 1 to Fig. 4, embodiment of the present invention provide, optical fiber biography is used for
It is defeated.Photoelectric conversion module 100 includes a circuit board 10, a posting 15 and a photoelectric coupling part 20.
Circuit board 10 includes a loading end 101.Photoelectric subassembly 104 is provided on loading end 101.Photoelectric subassembly 104 can be with
For optical signal launch component or optical signal receiving unit.Optical signal launch component can be laser diode（laser
diode）, optical signal receiving unit can be photodiode（photodiode）.
Posting 15 is substantially square, and offers a perforative opening 153.Posting 15 is arranged at holding for circuit board 10
On section 101, photoelectric subassembly 104 is located in opening 153.In the present embodiment, posting 15 is integrally formed with circuit board 10.
It in other embodiments, can also be by the way that the location hole worked in coordination be set on circuit board 10 and posting 15 respectively and is determined
The mode of position column, posting 15 is fixed on circuit board 10.
Photoelectric coupling part 20 includes end face 21, a upper surface 22 and a lower surface 23 opposite with upper surface 22.On
Surface 22 is mutually parallel with lower surface 23 and is vertically connected with end face 21.
Lower surface 23 is cascaded surface, is opened up thereon there are one the first groove 231, the shape and posting of the first groove 231
15 is consistent, and the size of the first groove 231 is slightly larger than the size of posting 15.First groove, 231 bottom is provided with corresponding to photoelectricity
First coupled lens 28 of component 104.First coupled lens 28 are integrally formed for convex lens and with the bottom of the first groove 231
It sets.
Second groove 221 there are one being opened up on upper surface 22.Second groove 221 includes the slot one parallel to upper surface 22
Plane 2210 and an inclined-plane 2211 set with slot plane 2210 in 45 degree of angles.The optical axis of first coupled lens 28 perpendicular to
Slot plane 2210 and with inclined-plane 2211 be in 45 degree of angles.
A pair of of positioning convex column 210 is extended on end face 21, while offers a slot 211.211 bottom of slot is provided with
Two coupled lens 26.Second coupled lens 26 correspond to an optical fiber（It is not shown）.In present embodiment, the light of the second coupled lens 26
The angle of axis and inclined-plane 2211 is 45 degree and is intersected at the optical axis of the first coupled lens 28 on inclined-plane 2211.Present embodiment
In, the second coupled lens 26 are convex lens, and are shaped in the bottom of slot 211.
During assembling, photoelectric coupling part 20 is placed on the loading end 101 of circuit board 10, the first groove 231 entangles posting
15.104 and first coupled lens 28 of photoelectric subassembly rough alignment at this time.Then, then fine position photoelectric subassembly is passed through
104 are accurately aligned with the first coupled lens 28, and then by the periphery dispensing in photoelectric coupling part 20, photoelectric coupling part 20 is consolidated
