Embodiment
Please refer to Fig.1, Fig. 2, Fig. 3 and Fig. 4, a kind of combining structure of photoelectric coupling lens module 10 include it is separable before
Lens unit 11, mirror lens unit 12 and rear lens unit 13, front lens unit 11, mirror lens unit 12 and rear lens list
The reflection lens module of the composition rotation light path of member 13.
Front lens unit 11 is used for being coupled with optical fiber, and mirror lens unit 12 is used for reflecting light incident thereon,
Rear lens unit 13 is used for being coupled with photoelectric cell (for example, light-emitting component and photoelectric detector), in this way, photoelectric coupling lens
Module 10 realizes that optical signal is transmitted between photoelectric cell and optical fiber.
Front lens unit 11 has some first lens 110 and two front positioning structures 111, and front lens unit 11 has phase
To first surface 11a and second surface 11b, wherein, the first lens 110 be located on first surface 11a be used for and optical fiber carry out
Optical coupling, the optical axis of the first lens 110 is parallel to each other, and front positioning structure 111, which is located on second surface 11b, to be used for making front lens list
Member 11 is positioned with mirror lens unit 12.Front positioning structure 111 can be cylinder or hole.
Mirror lens unit 12 has the 3rd surface 12a, the 4th surface 12b and the 5th surface 12c, and the 3rd surface 12a divides
Do not intersect vertically with the 4th surface 12b and the 5th surface 12c, the 4th surface 12b and the 5th surface 12c are parallel.4th surface 12b
It is recessed to form reflecting surface 120 to the 5th surface 12c, the angle between 120 and the 4th surface 12b of reflecting surface is 45 degree, the 3rd table
There are two the first location structures 121 on the 12a of face, there is two the second location structures 122, the first positioning on the 5th surface 12c
Structure 121 corresponds to the front positioning structure 111 on front lens unit 11, and the second location structure 122 is used for making mirror lens unit 12
Positioned with rear lens unit 13.First location structure 121 can be cylinder or hole, and equally, the second location structure 122 can be with
For cylinder or hole.
Rear lens unit 13 has opposite the 6th surface 13a and the 7th surface 13b, wherein, have on the 6th surface 13a
Two rear positioning structures 131, have some second lens 130 on the 7th surface 13b, the second lens 130 are used for and photoelectric cell
