Abstract
The invention discloses an optical fiber connector and a manufacturing method thereof. The optical fiber connector comprises a connector and at least one optical fiber which is integrally formed in the connector. The manufacturing method for the optical fiber connector comprises the following steps of: firstly, putting the optical fiber into a mould for forming the connector, setting a position and aligning; secondly, injecting raw materials of the connector into the mould; and finally, solidifying and shaping the connector, opening the mould and demoulding to obtain the optical fiber connector. The optical fiber is integrally formed in the connector, so that the optical fiber is accurately fixed in the connector and the optical fiber connector with better optical properties is manufactured.
Description
Technical field
The present invention relates to a kind of fiber connector, particularly relate to a kind of gluing process that saves, optical fiber accurately is fixed in the connector, and fiber connector and the manufacture method thereof of the light characteristic preferably that obtains.
Background technology
Optical fiber is a kind ofly can transmit light and fine glass fibre or the transparent plastic fiber of profile, comprises that the optical fiber of core and outer field protection are by cortex.When being applied to optical communication, assemble a connector at the one end usually, to form a fiber connector.Seeing also Fig. 1 and Fig. 2, is the headgear group of a fiber connector and the stereographic map that an optical fiber 7 one ends is assembled in this headgear group.This headgear group comprises a headgear 6 and a headgear handle 61, and the centre of this headgear 6 and headgear handle 61 offers a through hole 62.Optical fiber 7 can be penetrated by the through hole 62 of headgear handle 61, and the optical fiber 71 of optical fiber 7 one ends is passed by through hole 62, so the internal diameter of this through hole 62 is than the external diameter greater than optical fiber 7 and optical fiber 71.Therefore, be on 71 of optical fiber 7 and optical fibers, behind the binder 63, again optical fiber 71 to be penetrated in the through hole 62 earlier during assembling, this binder 63 is fixed in optical fiber 7 and optical fiber 71 in the through hole 62 of headgear group to use.
But, when optical fiber 7 assemblings, optical fiber 7 is positioned with very strict requirement, the contraposition deviation that is optical fiber 7 centers and through hole 62 aperture center must be less than 5um, and fix optical fiber 7 and connector by said method with a binder 63, when this optical fiber 71 penetrates in the through hole 62, this binder 63 can stick because of the sidewall of capillarity toward through hole 62, and pushing in the time of can penetrating because of optical fiber 71 makes binder 63 have bubble to produce, and because the expansion coefficient of bubble is bigger than solid, push optical fiber 71 so make bubble easily, make optical fiber 71 produce skew, or pushed and break by bubble, and then influence light-transfer characteristic, reduce the yield that optical fiber 7 engages with connector, and in the mode of 63 glue of binder, its accurate and complicated technology not only needs to use high-precision mounting equipment, also improves production cost simultaneously.
Summary of the invention
The objective of the invention is to provides a kind of gluing process that saves at above-mentioned the deficiencies in the prior art, optical fiber accurately is fixed in the connector, and obtains fiber connector and the manufacture method thereof of light characteristic preferably.
For achieving the above object, the invention provides a kind of fiber connector, comprise a connector and be shaped at least one interior optical fiber of connector.
The syndeton of described connector and optical fiber is at least one blind hole, and optical fiber takes shape in the blind hole.
Described fiber connector also comprises at least one transparent heterogeneous substrate, transparent heterogeneous substrate with optical fiber be shaped in connector blind hole one end and and the blind hole spacing of being separated by, the material of described transparent heterogeneous substrate is transparent glass or plastics.
The syndeton of described connector and optical fiber is at least one through hole, and optical fiber takes shape in the through hole.
The present invention also provides a kind of manufacture method of fiber connector, may further comprise the steps:
At first, at least one optical fiber is put into for the mould desired location of formed connected joint and carried out contraposition;
Then, inject the raw material of connector in the mould;
Behind last to be connected the curing molding, die sinking is the separable fiber connector that obtains.
As mentioned above, the present invention is one-body molded with optical fiber and connector, can omit optical fiber is assembled in step in the connector, do not need to apply in addition binder, therefore can avoid binder to solidify the problem of deformation and hole tolerance, and can avoid the generation of bubble effectively, and reduce and produce the contraposition skew when optical fiber is packed in the connector, thereby optical fiber accurately is fixed in the connector, and obtains the fiber connector of light characteristic preferably.

Embodiment
By describing technology contents of the present invention, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 3 to Fig. 6, fiber connector 100 of the present invention comprises a connector 1 and is shaped at least one optical fiber 2 in the connector 1.
This connector 1 is at least one blind hole (not indicating among the figure) with the syndeton of optical fiber 2, and optical fiber 2 takes shape in the blind hole.
Described fiber connector 100 also comprises at least one transparent heterogeneous substrate 3, and transparent heterogeneous substrate 3 is shaped in blind hole one end and and the blind hole spacing of being separated by of connector 1 with optical fiber 2.
The setting of transparent heterogeneous substrate 3 can increase light transmittance and the intensity of fiber connector 100.The surface of transparent heterogeneous substrate 3 can be the plane, or has curved surface or Fresnel (Fresnel) face or the diffraction pattern plane of optics deviation light effects.The material of transparent heterogeneous substrate 3 can be transparent glass or plastics.
This connector 1 can be at least one through hole (not indicating among the figure) with the syndeton of optical fiber 2, and optical fiber 2 takes shape in the through hole.
