The schematic diagram of II-II in Fig. 1 in Fig. 2.
Main element symbol description
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, and lens unit 10 is used for coupled fiber (not shown) and photoelectric conversion unit 20 and realizes the transmission of light signal between optical fiber and photoelectric conversion unit 20.
Lens unit 10 is roughly square, there are four first surface 111, second surface 112, the 3rd surface 113 and the 4th surfaces 114 that first place is connected, wherein, first surface 111 and the 3rd surface 113 are oppositely arranged, second surface 112 and the 4th surface 114 be oppositely arranged.
In addition, lens unit 10 also comprises the 5th surface 115 and the 6th surface 116 that are all connected with the 4th surface 114 with first surface 111, second surface 112, the 3rd surface 113.Wherein, the 6th surface 116 is protruded and is formed annular sway brace 120 to photoelectric conversion unit 20 towards photoelectric conversion unit 20 and edge part entirety, 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, first lens 117 and the second lens 118 are corresponding one by one, 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.The optical axis of the optical axis of first lens 117 and second lens 118 corresponding with first lens 117 is vertically intersected on reflecting surface 119, and the angle of optical axis and reflecting surface 119 is 45 degree.
In other embodiment, can form respectively a sway brace 120 in the place (i.e. four of six surface 116 corners) crossing with first surface 111, second surface 112, the 3rd surface 113 and the 4th surface 114, the 6th surface 116.
Photoelectric conversion unit 20 comprises substrate 21 and is electrically arranged on the optical transceiver cell 22 on substrate 21, and lens unit 10 is fixed on substrate 21 and by optical transceiver cell 22 and covers on substrate 21 with a glue processing procedure by sway brace 120.Substrate 21 can be circuit board, for example hard circuit board or flexible circuit board.Optical transceiver cell 22 comprises the light-emitting component (for example, laser diode or light emitting diode) emitting beam and the photoelectric detector that receives light.
First lens 117 is coupled with optical fiber, and the light of optical fiber output incides on reflecting surface 119 through first lens 117, is reflected after face 119 reflects and incides on the second lens 118, after the second lens 118 outgoing, is received by the light receiving element of optical transceiver cell 22; The light that the light-emitting component of optical transceiver cell 22 sends incides on reflecting surface 119 through the second lens 118, after reflecting surface 119 reflections, again through first lens 117 outgoing, is then coupled into Optical Fiber Transmission.
On substrate 21, the position of corresponding sway brace 120 has annular groove 210, and sway brace 120 is positioned at groove 210.Except groove 210, on substrate 21 around groove 210 there is the first barricade 30 and the second barricade 40 so that groove 210 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.The region of optical transceiver cell 22 between the second barricade 40.
In the time that sway brace 120 is positioned at the corner of lens unit 10, the position of groove 210 needs suitably to change equally.
In the time that lens unit 10 is fixed on substrate 21, first in the groove 210 between the first barricade 30 and the second barricade 40 on substrate 21, apply glue or the resisting medium 50 such as double sticky tape, again the sway brace of lens unit 10 120 is placed in the groove 210 between the first barricade 30 and the second barricade 40, so that lens unit 10 is fixed on substrate 21.
Because the sway brace 120 of lens unit 10 is fixed in the groove 210 of substrate 21 by resisting medium 50, increase the contact area of lens unit 10 with substrate 21, lens unit 10 and the adhesion of substrate 21 are strengthened; In addition, the first barricade 30 of substrate 21 and the second barricade 40 by lens unit 10 sandwicheds wherein, can further increase the engaging force of lens unit 10 and substrate 21 by this design, and 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.
