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 such as laser diode, photodiode, 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 photoelectric conversion unit, described photoelectric conversion unit has substrate, described lens unit has the sway brace towards described substrate, between described sway brace and described substrate, there is resisting medium so that described lens unit is fixed on described substrate, on described substrate, have the first barricade and the second barricade around described sway brace, described sway brace is between described the first barricade and the second barricade.
Compared to prior art, the lens unit of the optical communication module of the present embodiment is not only fixed on substrate with resisting medium, and the first barricade of substrate and the second barricade are by lens unit sandwiched wherein, can increase the engaging force of lens unit and substrate by this design, make lens unit and substrate junction make a concerted effort to strengthen.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, the optical communication module 100 that the embodiment of the present invention provides comprises lens unit 10 and photoelectric conversion unit 20.
Lens unit 10 is roughly square, and has four first surface 111, second surface 112, the 3rd surface 113 and the 4th surfaces 114 that first place is connected, and wherein, first surface 111 is relative with the 3rd surface 113, second surface 112 is relative with the 4th surface 114.
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 protruded and is formed sway brace 120, 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.
Photoelectric conversion unit 20 comprises substrate 21 and is arranged on the light Transmit-Receive Unit 22 on substrate 21, and lens unit 10 is fixed on substrate 21 and by light Transmit-Receive Unit 22 and covers on substrate 21 with sway brace 120.Light Transmit-Receive Unit 22 comprises the luminescence component (for example, laser diode or light emitting diode) emitting beam and the photoelectric detector that receives light.Substrate 21 is hard circuit board or flexible circuit board.
First lens 117 is coupled with optical fiber, and the light of optical fiber output incides on reflecting surface 119 through first lens 117, incides the second lens 118 after reflecting surface 119 is reflected, and after the second lens 118 outgoing, is 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.
On substrate 21 around sway brace 120 there is the first barricade 30 and the second barricade 40 so that sway brace 120 between the first barricade 30 and the second barricade 40.
The first barricade 30 and the second barricade 40 can by substrate 21, arrange thickness compared with other partly high anti-welding paint or other insulating material form.In the time that lens unit 10 is fixed on substrate 21, first the region between the first barricade 30 and the second barricade 40 on substrate 21 applies glue or the resisting medium 50 such as double sticky tape, again the sway brace of lens unit 10 120 is placed between the first barricade 30 and the second barricade 40, so that lens unit 10 is fixed on substrate 21.
Because lens unit 10 is not only fixed on substrate 21 with resisting medium 50, and the first barricade 30 of substrate 21 and the second barricade 40 are by lens unit 10 sandwicheds wherein, can increase the engaging force of lens unit 10 and substrate 21 by this design, lens unit 10 and substrate 21 adhesions are strengthened.
Be understandable that, those skilled in the art also can do other variation etc. and be used in design of the present invention 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.
