Embodiment
Refer to Fig. 1 to 4, there is disclosed the photoelectric conversion module 100 of first embodiment of the invention, comprise pcb board 10 and be installed on the optical coupling lens 20 on pcb board 10.
Pcb board 10 comprises a loading end 11, and this loading end 11 is provided with a line photoelectric conversion component 13.This photoelectric conversion component 13 can be photodiode, laser diode etc.This photoelectric conversion component 13 is arranged in straight line.
Optical coupling lens 20 comprises body 21, reference column 22, a line first plus lens 23 and a line second plus lens 24.
Body 21 is made with transparent plastic material, roughly in tabular, comprises one towards the bottom surface 210 of loading end 11 and a relative end face 211 parallel with bottom surface 210.This bottom surface 210 is the first optical surface, bottom surface 210 is formed and installs projection 213, installs projection 213 for optical coupling lens 20 is installed on pcb board 10.In the present embodiment, bottom surface 210 is formed with 4 and four corners that projection 213,4 installation projection 213 lays respectively at bottom surface 210 are installed.
This first plus lens 23 to be formed on this bottom surface 210 and and this photoelectric conversion component 13 one_to_one corresponding.
This end face 211 is parallel with this bottom surface 210, this end face 211 offers an end face groove 223, this end face groove 223 is rectangle, and body 21 also comprises one second optical surface 225, and this second optical surface 225 is positioned at the bottom of this end face groove 223 and parallel with this end face 211.This second plus lens 24 to be formed on this second optical surface 225 and and this first plus lens 23 one_to_one corresponding.In the present embodiment, this first plus lens 23 and this second plus lens 24 are convex lens.
This end face 211 is also formed with pilot hole 227.In the present embodiment, this pilot hole 227 is circular hole, and the number of this pilot hole 227 is two, and these two pilot holes 227 are positioned at the both sides of this end face groove 223 and penetrate this end face 211 and this bottom surface 210.
In present embodiment, this body 21, first plus lens 23 and the second plus lens 24 obtain by injection molding method is one-body molded.That is: the structure that is integrated of this body 21, first plus lens 23 and the second plus lens 24.
