Description
Technical field
The present invention relates to a kind of joints of optical fibre mechanism's part and the joints of optical fibre.
Background technology
Because Light Peak adopts optical transmission signal, therefore can use a large amount of lens and be used for coupling light, wherein most important is mechanism's part and circuit board.
Have lens on mechanism's part, the lens on the corresponding mechanism part are provided with light emitting diode and photodiode on the circuit board, and lens and light emitting diode, photodiode match and realize conversion between light signal and the electric signal.
Because the light path of lens and light emitting diode, photodiode needs certain distance, so, needing to have certain distance between lens and the circuit board, the two between form a cavity when being attached to mechanism's part on the circuit board this moment.Affect light path in order not allow aqueous vapor and dust enter cavity and make between mechanism's part and the circuit board relative fixingly, usually can at cavity and mechanism's part and the contacted part glue coating of circuit board, then toast with seal chamber.Only, in bake process, the air expanded by heating in the glue destroys inner encapsulation thereby the air of expansion produces strength.
Summary of the invention
In view of this, be necessary to provide a kind of joints of optical fibre mechanism part and joints of optical fibre of in bake process, discharging air.
A kind of joints of optical fibre, comprise joints of optical fibre mechanism part and circuit board, described joints of optical fibre mechanism part is arranged on the described circuit board, have lens, groove and plug end on the described joints of optical fibre mechanism part, has light emitting diode on the described circuit board, the zone of described light emitting diode is set to hold described light emitting diode on the corresponding described circuit board of described groove, described plug end is used for locating described joints of optical fibre mechanism part, described plug end has vent port, and described vent port is connected with described groove.
A kind of joints of optical fibre mechanism part, have lens, groove and plug end on the described joints of optical fibre mechanism part, described lens are positioned at described groove, and described plug end is used for locating described joints of optical fibre mechanism part, described plug end has vent port, and described vent port is connected with described groove.
Compared to prior art, joints of optical fibre mechanism part and the joints of optical fibre of present embodiment have the vent port that is connected with groove, and the air that expands in the bake process can be discharged through vent port, thereby the aqueous vapor of avoiding and dust enter the transmission that guarantees that signal is good.

Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please together consult Fig. 1 and Fig. 2, the joints of optical fibre 10 that the embodiment of the invention provides comprise circuit board 11 and mechanism's part 12, and mechanism's part 12 is arranged on the circuit board 11.
Have light emitting diode and photodiode (not shown) on the circuit board 11 to realize the conversion of light signal and electric signal.
In addition, have the first location structure 110, the first location structures 110 on the circuit board 11 and can be hole or cylinder.
Has the lens (not shown) on mechanism's part 12, for the sending and receiving of sending out with light emitting diode, photodiode is coupled the realization signal.Also be provided with groove 120, plug end the 121 and second location structure 122 on mechanism's part 12.
In addition, mechanism's part 12 can adopt the injection molding method manufacturing, and material is generally plastics.
Groove 120 is positioned at the geometric center of mechanism's part 12 and the light emitting diode on the corresponding circuits plate 11 and photodiode so that hold light emitting diode.
The second location structure 122 is positioned on the surface that mechanism's part 12 has groove 120.The second location structure 122 matches so that mechanism's part 12 is positioned on the circuit board 11 with the first location structure 110.Corresponding the first location structure 110, the second location structures 122 are cylinder or hole.
Then the light signal that light emitting diode sends is incident to the lens that are arranged on mechanism's part 12 in groove 120 interior propagation, and the photodiode of propagating to be arranged on the circuit board 11 at groove 120 from the light signal of lens outgoing receives.
When mechanism's part 12 is positioned on the circuit board 11 by the first location structure 110 and the second location structure 122, because the existence of groove 120 forms a cavity 13 between mechanism's part 12 and the circuit board 11.
When being positioned at mechanism's part 12 on the circuit board 11, can be at groove 120 inside and perimeter glue coating, then mechanism's part 12 is attached on the circuit board 11 the first location structure 110 and 122 alignment of the second location structure, mechanism's part 12 and circuit board 11 are put into baking box to be toasted, in bake process, air in the cavity 13 will expand, and the air of expansion is discharged by vent port 123, vent port 123 can be sealed afterwards.
Certainly because plug end 121 is used for carrying out combination with electronic equipment or other joints of optical fibre, in conjunction with after, vent port 123 is sealed automatically, therefore, can omit the processing procedure that seals vent port 123, thus the reduction cost.
Owing to be provided with the vent port 123 that is connected with groove 120 on mechanism's part 12 of the joints of optical fibre 10, the air that expands in the bake process can be discharged through vent port 123, thereby the aqueous vapor of avoiding and dust enter the transmission that guarantees that signal is good.
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 are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
