Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also Fig. 1, be the photoelectric conversion module 100 of first embodiment of the invention, this photoelectric conversion module 100 comprises the joints of optical fibre 10 and the reverberator 20 that is coupled with these joints of optical fibre 10.
These joints of optical fibre 10 comprise body 12 and multifiber 30.In the present embodiment, the number of optical fiber 30 is 4.This body 12 is for roughly being cubical translucent construction.This body 12 comprises a first surface 120 relative with reverberator 20, away from reverberator 20 and the second surface 121 parallel with first surface 120, and the 3rd surface 122 that is connected between first surface 120, the second surface 121.The both sides of this first surface 120 are formed with two connecting holes 123.These joints of optical fibre 10 also comprise a pickup groove 124 that extends to first surface 120 from second surface 121, pickup groove 124 roughly is square and forms opening on the 3rd surface 122, and comprise first inside surface 125 parallel with first surface 120, two respectively from the first inside surface 125 two ends vertical the second inside surface 126 that extends to second surface 121, and one connect the first inside surface 125 and the second inside surface 126 and three inside surface 127 parallel with the 3rd surface 122.Wherein, the angle theta between 126 relative the 3rd inside surfaces 127 inclinations of the second inside surface and the second inside surface 126 and the 3rd inside surface 127 is acute angle, thereby so that pickup groove 124 is the dovetail groove shape in the cross section that is parallel on the first inside surface 125.
Be formed with the optical fiber holding tank 128 of a plurality of cross sections semicircular in shape on the 3rd inside surface 127, the bearing of trend of optical fiber holding tank 128 is vertical with first surface 120.In other embodiments, the cross sectional shape of optical fiber holding tank 128 also can be V-shaped.Also offer a plurality of optical fiber accommodation holes 129 on the body 12, optical fiber accommodation hole 129 and optical fiber holding tank 128 are corresponding and communicate one by one respectively, and optical fiber accommodation hole 129 extends to first surface 120 from the first inside surface 125.Optical fiber holding tank 128 and optical fiber accommodation hole 129 are used for receiving optical fiber 30.
The 5th surface 202 offers reflection groove 204, and reflection groove 204 comprises a reflecting surface 205, and these reflecting surface 205 relative these first surfaces 120 and the 5th surface 202 tilt, and scribble reflecting material on this reflecting surface 205.The bottom that this reverberator 20 is relative with the 5th surperficial 202 also is equipped with the photoelectric conversion component (not shown), goes forward side by side in the optical fiber 30 in the light that photoelectric conversion component sends change direction of propagation after reflecting surface 205 reflections.After the light that optical fiber 30 is propagated reflects through reflecting surface 205, change the direction of propagation and arrive photoelectric conversion component.
When assembling, optical fiber 30 is placed in the optical fiber holding tank 128, and an end of optical fiber 30 inserts in the optical fiber accommodation hole 129 and arrives first surface 120.Be injected in the pickup groove 124 fixing glue 40 and curing, fixing glue 40 is fixed in optical fiber 30 on the body 12.Reference column 203 inserts in the connecting hole 123, thereby the joints of optical fibre 10 and reverberator 20 are fitted together.
Because the cross section of pickup groove 124 is the dovetail groove shape, after fixing glue 40 was solidified, the second inside surface 126 can stop fixing glue 40 to break away from pickup groove 124 from the 3rd surperficial 122 directions, thereby avoids optical fiber 30 to come off from pickup groove 124.In addition, the pickup groove 124 that is the dovetail groove shape is compared square pickup groove and can be had larger volume, thereby in the time of can avoiding glue, fixing glue 40 is overflowed from pickup groove 124.
Be understandable that, those skilled in the art also can do other variation in spirit of the present invention, all should be included within the present invention's scope required for protection.
