Embodiment
Below will combine accompanying drawing that the present invention is done further explain.
See also Fig. 1 and Fig. 2, the optical fiber coupled connector 10 that first embodiment of the invention provides comprises a shell 20 and a coupling part 30.This shell 20 has an accepting groove 22 and is used to accommodate this coupling part 30, and this coupling part 30 is used to transmit the light signal.
This accepting groove 22 has an inside surface 220, and this inside surface 220 is the plane.Be provided with a plurality of through holes 23 in this shell 20, an end opening of each through hole 23 is located at this inside surface 220.This through hole 23 is used in up-winding fiber (figure does not show) and the optic fibre hole 33 with fiber guides to this coupling part 30.In the present embodiment, the number of through hole 23 and optic fibre hole 33 is two.
This coupling part 30 roughly is rectangular structure, has two the first opposing and parallel end faces 31 and second end face 32, and one with the vertical end face 35 of this first, second end face 31,32, this first end face 31 is exposed outside.Be provided with a plurality of location structures at this first end face 31; For example detent 37; Usually, with the corresponding positioning convex column that is provided with of another optical fiber coupled connector (figure does not show) that this optical fiber coupled connector 10 is pegged graft each other, the two promptly realizes pegging graft through these a plurality of location structures.This first end face 31 also is provided with a plurality of lens 70, in the present embodiment, is provided with two lens.
Be provided with row's optic fibre hole 33 in this coupling part 30, these optic fibre hole 33 1 ends are opened at this second end face 32, the optical axis of each lens 70 and the central axes of optic fibre hole 33 of correspondence with it.These lens 70 and optical fiber (figure does not show) optical coupled that is housed in this optic fibre hole 33, promptly the light in the optical fiber can reflect this optical fiber coupled connector 10 by the quilt lens 70 corresponding with this optical fiber after penetrating.
The quantity that is appreciated that optic fibre hole 33 can change according to different design demand, is not limited to two, for example, can be three, and four, five etc.,
See also Fig. 2 and Fig. 3, this coupling part 30 is provided with a some glue groove 34, and this glue groove 34 is recessed to form in this second end face 32, and has removed part end face 35.This glue groove 34 has a bottom surface 340 and a side 341.This bottom surface 340 is parallel to end face 35, and with the planes at diameter place of this optic fibre hole 33, therefore manifest this optic fibre hole 33.This side 341 can with this bottom surface 340 vertical or out of plumb.This side 341 can be positioned near the mid point of this optic fibre hole 33, and be about to half optic fibre hole 33 and be exposed outside, thus can be through optical fiber fixedly being housed in this optic fibre hole 33 to 33 glue of the optic fibre hole that appears.
Be appreciated that this glue groove 34 can only be recessed to form by this end face 35 vertically downward, as long as appear this optic fibre hole 33.
This second end face 32 is provided with two reference columns 80 and two flexible members 40.Reference column 80 is right cylinder, and these two flexible members 40 are positioned at this second end face 32 and lay respectively at the both sides of this glue groove 34, also are positioned at the both sides of these row's optic fibre hole 33 outermost two optic fibre holes simultaneously, can guarantee the stability of this coupling part 30.This coupling part 30 is contained in this accepting groove 22 through these flexible member 40 elasticity.Flexible member 40 adopts spring in the present embodiment, and spring one end is fixed on this second end face 32 or this reference column 80, and an end and this inside surface 220 connect.These reference column 80 main effects are the distances that limit between this coupling part 30 and this shell 20, also are used for fixing better this flexible member 40 simultaneously.
The present invention preferably adopts two reference columns and two flexible members; If only be provided with one; This coupling part rocks in the time of can occur pegging graft, unsettled situation occurs, and more is unfavorable for accurate butt joint, and the flexible member of at least two reference columns and similar number can make this coupling part more stable; Can not produce unexpected inclination, promote accuracy greatly.
For preventing that this coupling part 30 from possibly ejected these accepting grooves 22, preferably, the edge of this accepting groove 22 is provided with that a stopper section 39 is used for and the groove 38 of first end face 31 of this coupling part 30 cooperatively interacts.This stopper section 39 is that an xsect is trapezoidal column, and the xsect of this groove 38 also is trapezoidal, so cooperates comparatively tight.If the elastic force of this flexible member 40 is little, this stopper section 39 can be omitted with groove 38.
When another optical fiber coupled connector (figure does not show) is pegged graft with this optical fiber coupled connector 10; It is inhomogeneous and cause coupling part 30 to produce the situation of inclination with respect to this shell 20 user's application of force to occur; But owing to be Elastic Contact between coupling part 30 and this shell 20, whole coupling part 30 is in quick condition, and this flexible member 40 applies a reverse acting force because of being squeezed to this coupling part 30; Thereby the position to this coupling part 30 is adjusted; Make it be stabilized in a comparatively ideal position, realize accurately butt joint, thereby guarantee the signal transfer efficiency between the optical fiber coupled connector.
Preferably, these two reference columns 80 are about the central shaft symmetry of this coupling part 30, so that this coupling part 30 is evenly adjusted.
See also Fig. 4; The optical fiber coupled connector 100 that second embodiment of the invention provides is basic identical with this optical fiber coupled connector 10; Optical fiber coupled connector 100 comprises coupling part 300 and shell 200; This coupling part 300 has two reference columns 800, and shell 200 has an inside surface 2200, and difference is: this inside surface 2200 is provided with two and these coupling part 300 corresponding location blind holes 240; The diameter of these two location blind holes 240 is greater than perhaps being slightly larger than the diameter of this reference column 800 can stretch into or shift out this location blind hole 240 so that have the reference column 800 of flexible member 400, thus the displacement of this coupling part 300 that extends.
Each embodiment of optical fiber coupled connector provided by the invention all can not comprise shell, because coupling part is packaged on each equipment after can independently making completion, and televisor for example, computing machine, notebook, mobile phone or the like.As long as coupling part comprises two fixed parts and two flexible members, can contact with the structural elasticity of accommodating this coupling part.
It is understandable that those skilled in the art also can do other variation in spirit of the present invention, all should be included within the present invention's scope required for protection.
