Abstract
An optical communication module comprises an optical fiber fixing unit and a lens unit, wherein the optical fiber fixing unit is used for fixing an optical fiber, the lens unit is used for in optical coupling with the optical fiber, and the optical fiber fixing unit is provided with a positioning hole. The optical communication module further comprises a positioning column made of a metal material, the lens unit is provided with a through hole, the positioning column is located in the through hole and matched with the positioning hole to enable the optical fiber fixing unit and the lens unit to be aligned.
Description
Technical field
The present invention relates to a kind of optical communication module.
Background technology
Optical communication module generally comprises optical fiber fixed cell and the lens unit that plug coordinates, and optical fiber fixed cell has the through hole of receiving optical fiber, has the lens with coupling fiber on lens unit.In addition, optical fiber fixed cell also has pilot hole, has reference column on lens unit, and pilot hole and reference column match and make lens and optical fiber align to realize optically-coupled.
But, the length of the relative optical fiber fixed cell of length of reference column, shorter, in the plug process of optical fiber fixed cell and lens unit, can be fractureed because of undercapacity, or cause optical fiber and lens can not exactitude position to affect the efficiency of optically-coupled.
Summary of the invention
In view of this, be necessary to provide a kind of at the larger optical communication module of plug procedural strength.
A kind of optical communication module, comprise optical fiber fixed cell and lens unit, described optical fiber fixed cell is used for fixing optical fiber, described lens unit is used for and described optical fiber coupling, on described optical fiber fixed cell, have pilot hole, described optical communication module further comprises the reference column of metal material, on described lens unit, has through hole, described reference column is arranged in described through hole, and described reference column matches with described pilot hole so that described optical fiber fixed cell and lens unit contraposition.
Compared to prior art, the optical communication module of the present embodiment coordinates with pilot hole with the reference column of metal material, because the intensity of reference column is larger, thereby makes in the plug process of optical fiber fixed cell and lens unit, reference column is frangibility, inclination not, has larger plug intensity.

Embodiment
Refer to Fig. 1, Fig. 2 and Fig. 3, the optical communication module 10 that the embodiment of the present invention provides comprises optical fiber fixed cell 11, lens unit 12 and reference column 13.
Optical fiber fixed cell 11 is generally made by plastic material, and adopts injection molding method one-body molded.Optical fiber fixed cell 11 has plural containing hole 110 and two pilot holes 111, containing hole 110 is arranged in parallel and is used for fixing optical fiber, containing hole 110 is through hole, containing hole 110 between pilot hole 111 and pilot hole 111 center online by containing hole 110 center, through hole or blind hole that pilot hole 111 is not limit for shape, be preferably circular port.
Lens unit 12 is generally made by plastic material, and adopts injection molding method one-body molded.On lens unit 12, there are lens 120 and two through holes 121 that quantity is identical with the quantity of containing hole 110.Lens 120 are corresponding so that lens 120 and the optical fiber coupling being contained in containing hole 110 one by one with containing hole 110, lens 120 are between through hole 121, and the optical axis of the online scioptics 120 at through hole 121 centers, the optical axis of the center line parallel lens 120 of through hole 121, through hole 121 radially outward forms stage portion 1211 away from one end of optical fiber fixed cell 11.
The shape of the corresponding pilot hole 111 of the shape of reference column 13 and through hole 121 and being made by metal material, for example, is become by iron or copper.One end of reference column 13 is radially protruded and is formed circular bulge loop 130, and the length of reference column 13 is at least the twice of through hole 121 degree of depth.Mode with mechanical tolerance between reference column 13 and through hole 121 closely cooperates, for example, and interference fit.When reference column 13 is arranged in through hole 121, bulge loop 130 is supported in stage portion 1211.
After reference column 13 closely cooperates with through hole 121, reference column 13 is stretched in pilot hole 111, thereby make optical fiber fixed cell 11 and lens unit 12 location, now, the center superposition of the optical axis of lens 120 and containing hole 110, guarantees the smooth coupling of light between optical fiber and lens 120.
Optical fiber fixed cell 11 and lens unit 12 position by the reference column 13 of metal material, because the intensity of reference column 13 is larger, in the plug process of optical fiber fixed cell 11 and lens unit 12, reference column 13 is difficult for being fractureed, tilting, thereby makes optical communication module 10 have larger plug intensity.
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, within all should being included in the present invention's scope required for protection.
