Embodiment
See also Fig. 1 and Fig. 2, the photoelectric commutator 20 of embodiment of the present invention comprises back up pad 21, light transmission main body 23, a plurality of first lens 24, a plurality of the second lens 25 and a plurality of optical fiber 26.A plurality of first lens 24 and a plurality of the second lens 25 embed and are arranged on light transmission main body 23, and a plurality of optical fiber 26 are inserted in light transmission main body 23.Back up pad 21 is arranged at the bottom of light transmission main body 23, is arranged at laser diode (not shown) top to support light transmission main body 23, makes light transmission main body 23 receive and transmit the light signal of laser diode outgoing.Photoelectric commutator 20 is used for transmission and transmitting photo-signal, it comprises that various functional modules are used for realizing various corresponding functions, as comprise be used to the laser diode that converts the electrical signal to light signal and for light signal being converted to the photodiode of electric signal, yet, for saving space, do not give detailed description in present embodiment.
Please consult simultaneously Fig. 3, light transmission main body 23 comprises that the first surface 231 that connects with back up pad 21 reaches the second surface 233 relative with first surface 231.A plurality of first lens 24 are convexly set on first surface 231, are used for the light signal of collimation incident light transmission main body 23.
Optical fiber mounting groove 237 is the square aperture groove, and it is opened on second surface 233 and towards the light near the second sidewall 2353 near the second sidewall 2353 and transmits main body one end opening.Optical fiber mounting groove 237 comprises the side 2373 of bottom surface 2371 and close the second sidewall 2353.A plurality of the second lens 25 intervals are convexly set on side 2373, are used for the light signal of collimation emergent light transmission main body 23.In present embodiment, side 2373 is parallel with the first side wall 2351.
Convex with optical fiber fixed part 2375 on bottom surface 2371, it is arranged at bottom surface 2371 away from an end of side 2373.It is block that optical fiber fixed part 2375 roughly is, and offers a plurality of V-type accepting grooves 2377 on its end face away from bottom surface 2371, is used for accommodating a plurality of optical fiber 26.Can understand, accepting groove 2377 also can be other shape, as trapezoidal, only need to stablize up-winding fiber 26 and gets final product.
