This second sidewall 12 offers 122, two through holes 122 of two through holes that cooperate with optical fiber 30 and is arranged in parallel and aims at two lens 15 respectively.This roof 13 offers a groove 130.This groove 130 is communicated with between these lens 15 and this through hole 122 and with this through hole 122.This groove 130 comprise the bottom 132, first side 134 and with these first side, 134 second side surface opposite 136.This through hole 122 runs through 134 backs, this first side and is communicated with this groove 130, and this second side 136 is near these lens 15 and be positioned on the focal plane of these lens 15.Two optical fiber 30 pass corresponding through hole 122 respectively and get in the groove 130, and the exiting surface of optical fiber 30 (figure does not show) is resisted against on second side 136.
Two support members 20 all are contained in this groove 130, and each support member 20 is positioned on the line of through hole 122 and corresponding lens 15, and promptly two support members 20 are aimed at two through holes 122 and two lens 15 respectively.Each support member 20 offers an arc accepting groove 22 and a lead angle 24.This arc accepting groove 22 extends to this second side 136 along the bearing of trend of optical fiber 30.This lead angle 24 and this arc accepting groove 22 joins and between through hole 122 and arc accepting groove 22.The bottom surface 220 of perisporium 240 relative these arc accepting grooves 22 of this lead angle 24 tilts.This arc accepting groove 22 is used to carry the part optical fiber 30 that gets in the groove 130.In this embodiment, two support members 20 are integrated formed structures with body 10.
Be appreciated that it is integrated formed structure that two support members 20 and body 10 are not limited in this embodiment, two support members 20 can also be the split molding structures with body 10.
Please combine Fig. 3 and Fig. 5, the form fit of the shape of this lid 40 and this groove 130 and this lid 40 are contained in this groove 130 to seal up this groove 130.This lid 40 comprises a upper surface 42 and a lower surface 44.The direction of lid 40 insertion grooves 130 is vertical with the length direction of through hole 122.Upper surface 42 flushes with roof 13 after 40 groups of lids are gone in the groove 130.This lower surface 44 offers a V-arrangement breasting groove 440.Second dip plane 444 that this V-arrangement breasting groove 440 has one first dip plane 442 and intersects with first dip plane 442.After lid 40 inserts groove 130; V-arrangement breasting groove 440 complements each other to form a receiving space 50 with up-winding fiber 30 with arc accepting groove 22, and bottom surface 220, first dip plane 442 and second dip plane 444 of arc accepting groove supports optical fiber 30 jointly so that optical fiber 30 is fixed in this receiving space 50.
In this embodiment, this lid 40 is fixed in this groove 130 through the gummed mode.This lid 40 is processed by high light transmissive material.Be appreciated that this lid 40 also can be fixed in this groove 130 through the mode that fastens with groove 130.
Please consult Fig. 4 to Fig. 6 in the lump, when assembling this optical fiber coupled connector 100, at first optical fiber 30 passes corresponding through hole 122 insertion grooves 130 and is carried in the arc accepting groove 22.Then further 136 moving fibers 30 are resisted against on second side 136 until the exiting surface of optical fiber 30 towards second side.Then, a glue is carried out in the exiting surface and 136 joints, second side of optical fiber 30.At last; Insert in lid 40 to the groove 130 and put glue and fix this lid 40, support optical fiber 30 jointly so that optical fiber 30 is fixed in this receiving space 50 so that lid 40 seals up the bottom surface 220 of this groove 130 and first dip plane 442, second dip plane 444 and arc accepting groove 22.
Optical fiber coupled connector 100 provided by the invention is utilized in and offers arc accepting groove 22 on the support member 20; On lid 40, offer V-arrangement breasting groove 440; And utilize the bottom surface 220 of arc accepting groove 22 and first dip plane 442 and second dip plane 444 of V-arrangement breasting groove 440 to support optical fiber 30 jointly so that optical fiber 30 is fixing; Only control and fixed fiber 30 avoiding, thereby guarantee that optical fiber 30 inserts the coupling precision of bodies 10 backs and lens 15 with blind hole.And; Be used for being arranged on the position that the focal plane with optical fiber 30 corresponding lens 15 coincides against second side 136 of the exiting surface of optical fiber 30; Be easy to arrive the coupling position best after 30 groups of optical fiber are gone into, further guaranteed the coupling precision of optical fiber coupled connector 100 with lens 15.
In addition; Because the lead angle 24 that joins with arc accepting groove 22 is set on the support member 20, and bottom surface 220 inclinations of the perisporium 240 relative arc accepting grooves 22 of lead angle 24, then when group is gone into optical fiber 30; Significantly reduce the exiting surface of optical fiber 30 and the interference and collision between the support member 20; The exiting surface that must exempt from optical fiber 30 breaks, problems such as scratch, thereby the transfer efficiency of assurance light signal.
It is understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
