Detailed description of the invention
Referring to Fig. 1, for the photoelectric conversion module 100 of first embodiment of the invention, this photoelectric conversion module 100 includes the joints of optical fibre 10 and the reflector 20 coupled with these joints of optical fibre 10.
These joints of optical fibre 10 include body 12 and multifiber 30.In present embodiment, the number of optical fiber 30 is 4.This body 12 is substantially in cubical translucent construction.This body 12 includes a first surface 120 relative with reflector 20, away from reflector 20 and the second surface 121 parallel with first surface 120 and the 3rd surface 122 being connected between first surface 120, 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 include a fixing groove 124 extended from second surface 121 to first surface 120, fixing groove 124 is substantially square and forms opening on the 3rd surface 122, and includes first inner surface 125, two parallel with first surface 120 vertical the second inner surface 126 extended to second surface 121 and connection first inner surface 125 and the second inner surface 126 and threeth inner surface 127 parallel with the 3rd surface 122 from the first inner surface 125 two ends respectively.Wherein, the second relative 3rd inner surface 127 of inner surface 126 tilts and angle theta between the second inner surface 126 and the 3rd inner surface 127 is acute angle, so that fixing groove 124 is dovetail channel-shaped in the cross section being parallel on the first inner surface 125.
Being formed with the fiber containment groove 128 of multiple cross sections semicircular in shape on 3rd inner surface 127, the bearing of trend of fiber containment groove 128 is vertical with first surface 120.In other embodiments, the cross sectional shape of fiber containment groove 128 also can be V-shaped.Being further opened with multiple fiber containment hole 129 on body 12, fiber containment hole 129 and fiber containment groove 128 one_to_one corresponding respectively and communicate, fiber containment hole 129 extends to first surface 120 from the first inner surface 125.Fiber containment groove 128 and fiber containment hole 129 are used for accommodating optical fiber 30.
Reflector 20 is tabular translucent construction, and including one towards the 4th surface 201 of the first surface 120 of the joints of optical fibre 10, and one from the 4th vertically extending 5th surface 202, side, surface 201.Two locating dowels 203 extend to first surface 120 from the two ends on the 4th surface 201 respectively.Locating dowel 203 is used for inserting in connecting hole 123, thus the joints of optical fibre 10 and reflector 20 is fitted together.
5th surface 202 offers reflection groove 204, and reflection groove 204 includes a reflecting surface 205, and this reflecting surface 205 this first surface 120 relative and the 5th surface 202 tilt, and this reflecting surface 205 scribbles reflecting material.The bottom that this reflector 20 is relative with the 5th surface 202 is also equipped with photoelectric conversion component (not shown), and the light that photoelectric conversion component sends changes the direction of propagation after being reflected face 205 reflection and enters in optical fiber 30.The light propagated from optical fiber 30 changes the direction of propagation after reflecting surface 205 reflects and arrives photoelectric conversion component.
Upon assembly, optical fiber 30 is placed in fiber containment groove 128, and the insertion fiber containment hole, one end 129 of optical fiber 30 is interior and arrives first surface 120.In fixing glue 40 is injected into fixing groove 124 and solidify, optical fiber 30 is fixed on body 12 by fixing glue 40.Locating dowel 203 is inserted in connecting hole 123, thus the joints of optical fibre 10 and reflector 20 is fitted together.
Owing to the cross section of fixing groove 124 is dovetail channel-shaped, after fixing glue 40 solidifies, the second inner surface 126 can stop fixing glue 40 to depart from fixing groove 124 from the 3rd direction, surface 122, thus avoids optical fiber 30 to come off from fixing groove 124.It addition, the fixing groove 124 in dovetail channel-shaped compares square fixing groove can have a bigger volume, thus when can avoid glue, fixing glue 40 is overflowed from fixing groove 124.
It is understood that those skilled in the art also can do other change in spirit of the present invention, within all should being included in scope of the present invention.
