Abstract
The invention discloses an optical communication module which comprises an optical fiber fixing unit and a lens unit. The optical fiber fixing unit comprises a number of through holes and positioning holes, wherein the through holes and the positioning holes are in parallel arrangement. The through holes are used for fixing optical fibers. The lens unit comprises a number of lenses and positioning columns. The lenses and the optical fibers are coupled. The positioning columns match the positioning holes, so that the optical fiber fixing unit and the lens unit are positioned. Two retaining walls are arranged on a surface of the lens unit, wherein the positioning columns are arranged on the surface, and the height of each retaining wall is greater than the height of each positioning column. The positioning columns are located between the retaining walls.
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 comprises through hole and the pilot hole that plural number is arranged in parallel, described through hole is used for fixing described optical fiber, described lens unit comprises plural lens and reference column, described lens are used for being coupled with described optical fiber, described reference column and pilot hole match and make optical fiber fixed cell and lens unit location, described lens unit has two barricades that are highly greater than described reference column on the surface with described reference column, and described reference column is between described barricade.
Compared to prior art, the optical communication module of the present embodiment, due to support and the guiding of barricade, makes to intercut the difficult inclination of optical fiber fixed cell, reference column in process and is difficult for being fractureed, thereby makes the plug intensity of optical communication module higher.
Brief description of the drawings
Fig. 1 is the schematic diagram of embodiment of the present invention optical communication module.
Fig. 2 is the decomposing schematic representation of embodiment of the present invention optical communication module.
Main element symbol description
Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 and Fig. 2, the optical communication module 10 that the embodiment of the present invention provides comprises optical fiber fixed cell 11 and lens unit 12.
Optical fiber fixed cell 11 structure that is roughly square, has the through hole 110 that plural number is arranged in parallel, and through hole 110 is used for accommodating and fixed fiber.On optical fiber fixed cell 11, also have two pilot holes 111, the online online and through hole 110 by through hole 110 centers at pilot hole 111 centers is between two pilot holes 111.Through hole or blind hole that pilot hole 111 can not limit for shape.
Lens unit 12 has the lens 120 that quantity is identical with through hole 110 towards one end of optical fiber fixed cell 11, carry out optically-coupled so that lens 120 and optical fiber are corresponding one by one.In addition, lens unit 12 has two reference columns 121 and two barricades 122 on the surface with lens 120, and lens 120 and reference column 121 are between two barricades 122.The short transverse of the substantially parallel reference column 121 of length direction of barricade 122, distance between barricade 122 by the direction away from reference column 121 to increasing gradually near the direction of reference column 121 and the narrowest ground general plan equals the thickness of optical fiber fixed cell 11, so that optical fiber fixed cell 11 can stretch between barricade 122.
The optical axis of the online scioptics 120 at two reference column 121 centers, and lens 120 are between reference column 121.Reference column 121 inserts in pilot hole 111, and optical fiber fixed cell 11 and lens unit 12 are located mutually, and the optical axis of lens 120 and the center of optical fiber are aimed at.
Barricade 122 is one-body molded with lens unit 12, and the height of barricade 122 is at least the twice of reference column 121 height.
In the time that optical fiber fixed cell 11 coordinates with lens unit 12, optical fiber fixed cell 11 is gradually near lens unit 12, and reference column 121 stretches in pilot hole 111 under the guiding of barricade 122, to complete coordinating of optical fiber fixed cell 11 and lens unit 12; In addition, because the distance between barricade 122 constantly increases, optical fiber fixed cell 11 can be imported smoothly also compacted.
In the plug process of optical fiber fixed cell 11 and lens unit 12, due to support and the guiding of barricade 122, make the difficult inclination of optical fiber fixed cell 11, reference column 121 in plug process be difficult for being fractureed, thereby make optical communication module 10 there is higher 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 do according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
