Abstract
The invention discloses an optical communication module, which comprises a lens unit and a photoelectric conversion unit coupled with the lens unit, wherein the photoelectric conversion unit is provided with a circuit board; the lens unit is fixed on the circuit board; two opposite side faces where the main body and the circuit board are contacted extend to form extending parts basically parallel to the circuit board; and the bottom surface and the surface of each extending part have glue to enable the lens unit to be fixed on the circuit board.
Description
Technical field
The present invention relates to a kind of optical communication module.
Background technology
In the encapsulation procedure of Light Peak, first can first on circuit board, complete the operation of laser diode, photodiode etc., on circuit board, coat afterwards fixing glue, again lens unit is aimed to laser diode, photodiode is put, for optical communication, between lens unit and laser diode, photodiode, the precision of contraposition is extremely important.
In the fixing processing procedure of lens unit, first can coat fixing glue at circuit board, then lens unit is put to suitable position, depending on the kind difference of glue, see through different modes by adhesive curing.Under this processing procedure, glue only can contact with lens unit at bottom.After the lens unit of Light Peak module also can with other mechanism's part combination, if the therefore engaging force deficiency of lens unit and circuit board, while joint with other mechanism's part afterwards, may cause the skew of lens unit position, or even cause coming off of lens unit.
Summary of the invention
In view of this, be necessary to provide the optical communication module that a kind of lens unit and circuit board adhesion are strong.
A kind of optical communication module, comprise lens unit and the photoelectric conversion unit with described lens unit coupling, described photoelectric conversion unit has circuit board, described lens unit is fixed on described circuit board, the side that described body is relative with two of described circuit board contact extends to form the extension of substantially parallel described circuit board, and described extension bottom surface and surface have glue so that described lens unit is fixed on described circuit board.
Compared to prior art, the lens unit of the present embodiment has extension, while making lens unit be fixed on circuit board, not only between lens unit bottom and circuit board, there is glue, and there is glue equally between the periphery of lens unit and circuit board, thereby strengthen the adhesion between lens unit and circuit board, when lens unit and other mechanism's part engage, can not cause position skew and come off.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also shown in Fig. 1, Fig. 2 and Fig. 3, the optical communication module 100 that the embodiment of the present invention provides comprises lens unit 10 and photoelectric conversion unit 20.
The first extension 11, second surface 112 and the 4th surface 114 that first surface 111 and the 3rd surface 113 extend to form substantially parallel circuit board 21 near the position of circuit board 21 extends to form the second extension 12 of substantially parallel circuit board 21 near the position of circuit board 21.
In addition, lens unit 10 also comprises the 5th surface 115 and the 6th surface 116 that are connected with first surface 111, second surface 112, the 3rd surface 113 and the 4th surface 114, wherein, the 6th surface 116 is near circuit board 21, on first surface 111, there is the parallel first lens of plural optical axis 117, the 6th surface 116 has the second lens 118 that quantity is identical with first lens 117 quantity, the 5th surface 115 is recessed to form reflecting surface 119 to the 6th surface 116, and reflecting surface 119 is used for reflecting the light of first lens 117 and the second lens 118 outgoing.First lens 117 and an optical fiber are coupled, the light of optical fiber output incides on reflecting surface 119 through first lens 117, after reflecting surface 119 is reflected, incide the second lens 118, after the second lens 118 outgoing, received by the photodiode of light Transmit-Receive Unit 22; The light that the light emitting diode of light Transmit-Receive Unit 22 sends incides on reflecting surface 119 through the second lens 118, after reflecting surface 119 reflections, through first lens 117 outgoing, is then coupled into Optical Fiber Transmission.
In the time that lens unit 10 is fixed on circuit board 21, first apply glue 30 at circuit board 21, lens unit 10 is put to the suitable position of circuit board 21 again, then apply glue 30 at the first extension 11 and the second extension 12 surfaces, finally by adhesive curing, thereby lens unit 10 is fixed on circuit board 21.
Because lens unit 10 has the first extension 11 and the second extension 12, while making lens unit 10 be fixed on circuit board 21, not only between lens unit 10 bottoms and circuit board 21, there is glue 30, and there is glue 30 equally between the periphery of lens unit 10 and circuit board 21, thereby strengthen the adhesion between lens unit 10 and circuit board 21, when lens unit 10 and other mechanism's part engage, can not cause position skew and come off.
Certainly, also can the first extension 11 be only set on first surface 111 and the 3rd surface 113 or only on second surface 112 and the 4th surface 114, the second extension 12 be set.
Be understandable that, those skilled in the art also can do other and change in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these do according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
