Embodiment
Below with reference to accompanying drawing, the present invention is described in further detail.
Refer to Fig. 1 and Fig. 2, the optical-fiber coupling 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 for accommodating this coupling part 30, and this coupling part 30 is for transmission light signal.
This accepting groove 22 has an inside surface 220, and this inside surface 220 is plane.Be provided with multiple through hole 23 in this shell 20, the one end open of each through hole 23 is located at this inside surface 220.This through hole 23 is for up-winding fiber (not shown) and by fiber guides in the optic fibre hole 33 of 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 in rectangular structure, has two opposing and parallel the first end face 31 and the second end faces 32, and the end face 35 that vertical with this first, second end face 31,32, and this first end face 31 is exposed outside.Multiple location structure is provided with at this first end face 31, such as detent 37, usually, optical-fiber coupling connector (not shown) is corresponding is provided with positioning convex column with another of the mutual grafting of this optical-fiber coupling connector 10, and namely the two realize grafting by the plurality of location structure.This first end face 31 is also provided with multiple 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, this optic fibre hole 33 one end is opened at this second end face 32, the optical axis of each lens 70 and the central axes of optic fibre hole 33 corresponding with it.These lens 70 and the optical fiber (not shown) optical coupled be housed in this optic fibre hole 33, can be reflected this optical-fiber coupling connector 10 after the light injection namely in optical fiber by the lens 70 corresponding with this optical fiber.
Be appreciated that the quantity of optic fibre hole 33 can need according to different designs and change, being not limited to two, such as, can be three, four, five etc.,
Refer to 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 eliminates portion top surface 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 the planes overlapping at a diameter place with this optic fibre hole 33, therefore manifest this optic fibre hole 33.This side 341 can or out of plumb vertical with this bottom surface 340.This side 341 can be positioned near the mid point of this optic fibre hole 33, is exposed outside by half optic fibre hole 33, thus can by being fixedly housed in by optical fiber in this optic fibre hole 33 to the optic fibre hole appeared 33 glue.
Be appreciated that this glue groove 34 can be only 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 in 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, are also positioned at the both sides of outermost two optic fibre holes of this row's optic fibre hole 33 simultaneously, can ensure the stability of this coupling part 30.This coupling part 30 is contained in this accepting groove 22 by this 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 one end and this inside surface 220 abut against.This reference column 80 Main Function limits the distance between this coupling part 30 and this shell 20, simultaneously also for fixing this flexible member 40 better.
The present invention preferably adopts two reference columns and two flexible members, if only arrange one, when there will be grafting, this coupling part rocks, unstable situation occurs, more be unfavorable for accurate docking, and the flexible member of at least two reference columns and identical number can make this coupling part more stable, unexpected inclination can not be produced, greatly promote accuracy.
For preventing this coupling part 30 may be ejected this accepting groove 22, preferably, the edge of this accepting groove 22 is provided with a stopper section 39 and cooperatively interacts for the groove 38 of the first end face 31 with this coupling part 30.This stopper section 39 is an xsect is trapezoidal column, and the xsect of this groove 38 is also trapezoidal, so coordinates 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 coupling connector (not shown) and this optical-fiber coupling connector 10 grafting, may occur that user exerts a force uneven and causes coupling part 30 to produce relative to this shell 20 the situation of inclination, but owing to being Elastic Contact between coupling part 30 and this shell 20, whole coupling part 30 is in quick condition, this flexible member 40 applies a reverse acting force because being squeezed to this coupling part 30, thus the position of this coupling part 30 is adjusted, it is made to be stabilized in a comparatively ideal position, realize accurately docking, thus the signal transmission efficiency between guarantee optical-fiber coupling connector.
Preferably, these two reference columns 80 are symmetrical about the central shaft of this coupling part 30, evenly to adjust this coupling part 30.
Refer to Fig. 4, the optical-fiber coupling connector 100 that second embodiment of the invention provides is substantially identical with this optical-fiber coupling connector 10, optical-fiber coupling connector 100 comprises coupling part 300 and shell 200, this coupling part 300 has two reference columns 800, shell 200 has an inside surface 2200, difference is: this inside surface 2200 is provided with two Blind locating holes 240 corresponding with this coupling part 300, the diameter of these two Blind locating holes 240 be greater than or slightly larger than this reference column 800 diameter with make band have elastic component 400 reference column 800 can stretch into or shift out this Blind locating holes 240, thus lengthen the displacement of this coupling part 300.
Each embodiment of optical-fiber coupling connector provided by the invention all can not comprise shell, because coupling part is packaged into after can independently having manufactured on each equipment, and such as televisor, computing machine, notebook, mobile phone etc.As long as coupling part comprises two fixed parts and two flexible members, can contact with the structural elasticity of this coupling part of collecting.
Be understandable that, those skilled in the art also can do other change in spirit of the present invention, all should be included within the present invention's scope required for protection.
