Embodiment
Refer to Fig. 1 and Fig. 2, the optical-fiber coupling connector mechanism member 10 that first embodiment of the invention provides is applied in optical-fiber coupling connector and is used for fixing optical fiber 15.
Mechanism member 10 has relative first surface 11 and second surface 12 and the relative the 3rd surface 13 and the 4th surface 14.3rd surface 13 is recessed to form several optic fibre holes 100 to the 4th surface 14, and optic fibre hole 100 is used for fixing optical fiber 15 for through hole and makes optical fiber 15 protrude the 4th surface 14, and the diameter of optical fiber 15 is
.First surface 11 and the 4th surperficial 14 junctions are recessed to form groove 110 to second surface 12 and the 3rd surface 13 respectively simultaneously, the shape of groove 110 is similar dustpan-shaped, namely groove 110 has second side 1103, first side 1102 relative with two, side 1102, bottom surface 1101, first between two the second sides 1103.
In other embodiments, groove 110 also can comprise two sides, namely groove 110 presents triangle, and two sides are intersected.
In addition, several optic fibre holes 100 are all positioned at the below of the bottom surface 1101 of groove 110.
Bottom surface 1101 is inclined-plane, and the angle between itself and the 4th surface 14 is
, bottom surface 1101 and the 4th surperficial 14 junctions apart from the distance bottom optic fibre holes 100 are
.
Optical fiber 15 is fixed on after in optic fibre hole 100, consistent in order to make light 15 protrude the length on the 4th surface 14, generally needs to adopt focusing angle be
laser beam 16(Fig. 2 in be amplify after laser beam, really not so in reality) cutting optical fibre 15, be to make the length that optical fiber 15 protrudes the 4th surface 14
, namely
after laser beam cutting, the length that optical fiber 15 is reserved, that is, in optical-fiber coupling connector, optical fiber 15 needs protrusion the 4th surface 14 and length is
, and when excising, the center of the central ray L vertical fiber 15 of laser beam 16, and in order to not make laser beam 16 burn mechanism member 10,
,
,
between should meet following relational expression:
, and
.
When
,
time, the lower surface of laser tube bank 16 contact optical fiber 15, the outermost layer of laser beam 16 is just crossing with bottom surface 1101; And work as
,
time, in whole cutting process, laser beam 16 all can not contact with mechanism member 10, so laser beam 16 can not be burnt mechanism member 10.
Because the bottom surface 1101 of groove 110 has distance apart from optic fibre hole 100
and angle
, thus make laser beam 16 when cutting optical fibre 15, mechanism member 10 of can not burning.
Refer to Fig. 3, the optical-fiber coupling connector mechanism member 20 that second embodiment of the invention provides has the optic fibre hole 200 of groove 210 and receiving optical fiber 15 equally.
Groove 210 has side, bottom surface 2101, first 2102 and the second side 2303, and bottom surface 2101 and the first side 2102 and the second side 2103 intersect vertically, and bottom surface 2101 is apart from the distance bottom optic fibre hole 200
same satisfied
, wherein,
,
,
definition with the first embodiment.
When
time, the lower surface of laser tube bank 16 contact optical fiber 15, the outermost layer of laser beam 16 is just crossing with bottom surface 2101; And work as
time, in whole cutting process, laser beam 16 all can not contact with mechanism member 20, so laser beam 16 can not be burnt mechanism member 20 equally.
Be understandable that, those skilled in the art also can do other change etc. and be used in design of the present invention, as long as it does not depart from technique effect of the present invention in spirit of the present invention.These changes done according to the present invention's spirit, all should be included within the present invention's scope required for protection.
