Description
Technical field
This use is novel to relate to a kind of how fine tail optical fiber.
Background technology
As everyone knows, kapillary has been widely used in various connectors and the optic communication device, and the main at present kapillary that uses mostly is single hole, diplopore greatly, and three holes, four hole kapillaries also have use.Porous capillary is core parts of making how fine tail optical fiber, and along with the passage densification demand of optic communication device, the purposes of accurate how fine tail optical fiber seems more and more important.But because the restriction of porous capillary price and dimensional accuracy, in device channel densification process, porous capillary has become one of components and parts of needing badly solution.
At present when making optic communication device, all be to use anchor clamps under the situation that minute adjustment is aimed at, to fix being connected between tail optical fiber and the function element by glue, use this method for making, the curing of minute adjustment anchor clamps and glue all needs the long time, and the price of glue and reliability are also seriously restricting product price and properties of product.
Summary of the invention
Problem to be solved in the utility model provides a kind of novel how fine tail optical fiber, and easily manufactured, cost is low also accurately to be connected with abutment element.For this reason, the utility model by the following technical solutions: it comprises the folded polylith substrate of establishing; Each substrate is provided with for many articles the one v type grooves placing optical fiber, be placed with optical fiber in the described v type groove, be respectively equipped with the 2nd v type groove that supplies the placement positioning pin in the both sides of described many articles the one v type grooves, how fine relative position between described the 2nd v type groove is corresponding with the location socket on the abutment element of described tail optical fiber, and how fine the position of described optical fiber is corresponding with the fiber position on the abutment element of described tail optical fiber.
Owing to adopt the technical solution of the utility model, can go out the tail optical fiber substrate that needs are made according to the STRUCTURE DECOMPOSITION of abutment element, and carve the v type groove of various sizes size on substrate according to designing requirement, number of substrates and size and v type groove position and size all design according to product needed.Can accurately with the location socket on the abutment element end face be connected at the register pin that stretches out on the product end surface, thereby realize that optical fiber docks with the precision of optical fiber, for realizing its closed butt joint, only need use jump ring or similarly mechanical adaptive getting final product in elements on either side, the utility model has been save traditional anchor clamps and has been regulated and two steps of glue curing, improve product packaging efficiency and reliability of products, reduced cost of products simultaneously.

Embodiment
With reference to accompanying drawing.The utility model comprises the folded polylith substrate of establishing, each substrate is provided with many for a v type groove 6 of placing optical fiber 7, be placed with optical fiber 7 in the described v type groove, the quantity and the position of the quantity of substrate, a v type groove determined by abutment element 11, makes optical fiber 7 can dock with optical fiber 13 in the abutment element 11.Be provided with four substrates 2,3,4,5 in the present embodiment altogether, described substrate with in glass and the plastic resin any one as material.Described optical fiber flushes with the port of a v type groove at the end face of described how fine tail optical fiber in the face of abutment element.
Be respectively equipped with the 2nd v type groove 8 that supplies placement positioning pin 1 in the both sides of described many articles the one v type grooves, the 2nd v type groove is big than a v type groove, as shown in Figure 1, the 2nd v type groove on the adjacent substrate cooperates in the 2nd v type groove that same register pin can be in simultaneously match on the adjacent substrate in twos, thereby can further improve bearing accuracy.Be provided with register pin 1 in described the 2nd v type groove, how fine relative position between described the 2nd v type groove is corresponding with the location socket 12 on the abutment element 11 of described tail optical fiber, make the register pin that therefrom stretches out can insert described location socket 12, how fine the position of described optical fiber is corresponding with the fiber position on the abutment element of described tail optical fiber.
Concrete implementation step is as follows:
The preparation of v groove substrate: prepared substrate and on substrate according to the design size cutting, designing requirement need be tested and reach in the precision and the position of the v groove of carving.Substrate is cleaned up, note cleaning method, can not in cleaning process, crash through product or make product edge damage or crackle occur; Locating slot on all substrates all is " v " type groove of producing by the machining of precision, v type design has guaranteed the reliable and stable of the precision positioning of optical fiber and register pin and position, the size and the position of v type groove can be set flexibly according to product needed, convenient number of fibers and the change fiber array spacing adjusted, the high precision of machining has guaranteed every optical property of product, can satisfy the densification requirement of multichannel light device, improve communication quality.
Optical fiber assembling and register pin assembling: optical fiber to be installed is positioned in the v type groove, use assembling pressing plate pressed fiber, from a v type groove rear portion point glue, note the consumption of glue, glue is oozed along the tip 10 of an optical fiber and a v type groove to be dropped down, and do not make glue flow to optical fiber top, use UV light source solidified glue.After for example on substrate 2, having assembled optical fiber, use is with the bottom optical fiber of quadrat method assembling substrates 3, then register pin is positioned in the 2nd v type groove 8, substrate 3 is placed on the substrate 2 by the 2nd v type groove 8 and register pin, 9 fills up glue and solidified glue then between substrate 2 and substrate 3.Make upper strata, substrate 4, the substrate 5 of the assembling substrates 3 that uses the same method.
Grinding and polishing product end surface: need to deviate from if certain of this product need be stretched out maybe register pin, then this must use release agent to handle before assembling to register pin, and before product grinds, need earlier this to be deviate from register pin, grind at product and again register pin is penetrated this dowel hole after finishing or do not wear.The optical fiber that will guarantee product end surface during grinding and polishing all polishes and the end face roughness can meet design requirement.Need to use relevant device check polishing effect after the polishing, confirm the product quality of finish, guarantee the product optical property.If register pin need not to stretch out end face, then directly product is carried out grinding and polishing and checks that quality of finish gets final product.
The selection of register pin and size all design according to product requirement, also can select different register pins for use in the identical product according to the design needs, the register pin that for example needs the demoulding, register pin use metal bar not need the then use optical fiber of the demoulding as register pin as register pin.
