A kind of method for forming micro-join hole of the joints of optical fibre, the method is to be stretched under heating status by the rectangular strip blout base material with optical fiber connecting hole making the joints of optical fibre, its lateral dimension is made to reduce, the diameter simultaneously making its optical fiber connecting hole narrows down to corresponding with fibre diameter, forms optical fiber and connects micropore.Invention not only simplifies processing technique, drastically increase working (machining) efficiency, and be effectively increased raw-material utilization rate, reduce production cost, product quality has been effectively ensured simultaneously.
Description
[technical field]
The present invention relates to connect the quartzy interface unit of optical fiber (optical fibers), particularly relate to the method for forming micro-join hole of a kind of joints of optical fibre.
[background technology]
Optical-fibre communications is a kind of mode utilizing light and optical fiber transmission information, belongs to the one of wire communication.Light just can carry information after modulation.From the eighties, optical-fibre communications makes telecommunications industry create revolutionary variation.The advantages such as fiber optic communication is big with its transmission capacity, good confidentiality and obtain high speed development, and have become as current topmost wire communication mode.The two ends of optical fiber used in optical-fibre communications field need to arrange the adapter being connected with optical-fibre communications equipment, and adapter is made up of quartz substrate.As shown in Figure 1 and Figure 2, traditional joints of optical fibre are to open V-shaped groove 2 on quartz base plate 1, then that optical fiber 3 is bonding with V-shaped groove 2, then with the clamping of one piece of cover plate 4.It will be apparent that this kind of connected mode is the most loaded down with trivial details, wastes again material, and cause the increase of processing cost.
[summary of the invention]
Present invention seek to address that the problems referred to above, and provide a kind of processing method simple, efficiency is high, low cost, can the method for forming micro-join hole of the effectively save raw-material joints of optical fibre.
For achieving the above object, the present invention provides the method for forming micro-join hole of a kind of joints of optical fibre, the method is to be stretched under heating status by the rectangular strip blout base material with optical fiber connecting hole making the joints of optical fibre, its lateral dimension is made to reduce, the diameter simultaneously making its optical fiber connecting hole narrows down to corresponding with fibre diameter, forms optical fiber and connects micropore.
Optical fiber connects micropore and is provided in quartz substrate centrally and axially through hole.
Quartz substrate aperture of its lateral dimension and optical fiber connecting hole in drawing process is scaled down.
Optical fiber connects a diameter of 120～130 microns of micropore.
Optical fiber connects a diameter of 127 microns of micropore.
One end end face central authorities in described quartz substrate are provided with and are connected the bellmouth expanded outwardly that micropore is connected with described optical fiber.
The contribution of the present invention is, traditional in advance quartz substrate need to be cut owing to changing, open the loaded down with trivial details techniques such as V-shaped groove, not only simplify processing technique, drastically increase working (machining) efficiency, and it is effectively increased raw-material utilization rate, reduce production cost, product quality has been effectively ensured simultaneously.

[detailed description of the invention]
The following example is further explanation of the present invention, does not constitutes any limitation the present invention.
The method for forming micro-join hole of the joints of optical fibre of the present invention is as shown in Figure 3, Figure 4, first intercept one section of rectangular strip blout base material 5, its lateral dimension is 20mm × 20mm, and its length, less than the length of joints of optical fibre product, has through axial optical fiber connecting hole in quartz substrate central authorities.
The present invention is characterized by, and is stretched by described quartz substrate 5 quartz wire drawing machine so that it is horizontal size, i.e. length and width size reduction is to 2.5mm × 2.5mm, and length then increases to the size 6～8mm needed for the joints of optical fibre under heating status.Along with reducing of quartz substrate length and width size, the diameter of its optical fiber connecting hole narrows down to corresponding with fibre diameter the most simultaneously, forms micron-sized optical fiber and connects micropore 6.Quartz substrate, in drawing process, should make the aperture scaled down of its lateral dimension and optical fiber connecting hole.The optical fiber of final molding connects a diameter of 120～130 microns of micropore 6, and preferably 127 microns, it belongs to the micropore of capillary pass.Quartz substrate 5, after drawing and forming, can insert optical fibers into optical fiber and connect in micropore 6.Fix for ease of optical fiber to be connected micropore 6 with optical fiber, one end end face central authorities in described quartz substrate 5 are provided with and are connected the bellmouth 7 expanded outwardly that micropore 6 is connected with described optical fiber, and the end of optical fiber can be adhesively fixed with quartz substrate 5 with bonding agent at this bellmouth 7.
Taking this, the present invention defines the joints of optical fibre with the integral type that optical fiber connects micropore by drawing process.
