Abstract
The utility model relates to an optical fiber insert core which is provided with a hole for inserting an optical fiber for optical axis butting. The insert core is made of a metal material through electroforming. Compared with the traditional zirconia ceramic insert core, the optical fiber insert core has simple manufacturing, flexibility, high precision, low cost and large-scale production, and is especially applicable to the manufacturing of various heterogenic optical fiber insert cores.
Description
Technical field
The utility model relates to the lock pin on a kind of joints of optical fibre that are used for being connected between optical fiber connection or optical fiber and the optical device.
Background technology
When carrying out being connected between connection between the optical fiber or optical fiber and the optical device, the high precision butt joint that how to guarantee optical axis is extremely important, the parts that use in the optical axis butt joint are fiber stub, it is the vitals on the optical connector, and lock pin is that starting material are made mostly with the zirconia ceramics in the prior art.It mainly is because it has good wearing quality as starting material, has the not advantage of cracky of high tenacity in stupalith that the quilt of zirconia ceramics uses in a large number.The making of ceramic insertion core is made by blank and precision optical machinery processing two is partly formed.Wherein, the blank making is that injection moulding in the mould of special use forms through high temperature sintering then after the granulation with the high-purity zirconium dioxide powder stock of special processing.And then precise finiss processing, to reach the machining precision of submicron order.Above-mentioned complex manufacturing technology, yield rate is low, thereby make its reduce cost and production in enormous quantities aspect be restricted.Especially aspect the development of miniaturization, multiple-core and the abnormal shapeization of fiber stub, more be subjected to severely restricts.
The utility model content
The utility model purpose is exactly to propose a kind of simple for production, flexible and higher lock pin of precision in order to overcome the deficiencies in the prior art.
In order to reach the foregoing invention purpose, the technical solution of the utility model is: a kind of fiber stub, and it has and is used to insert optical fiber to carry out the hole of optical axis butt joint, and described lock pin is formed by the metal material electroforming.
In further implementing according to technique scheme institute, described metal material is a nickel, because the nickel corrosion resistance is better, is difficult for oxidation in air, the low and electroplating technology comparative maturity of price.
The shape in described lock pin hole is identical with the shape of electroplating with plug, thereby can make all kinds of special-shaped optical fibre lock pins according to the needs that use.
The precision of described lock pin aperture and external diameter is a micron order.
Described lock pin is divided into two kinds of single mode lock pin and multimode lock pins.
The aperture precision error of described single mode lock pin below the 0.07um, external diameter trueness error scope is between ± the 0.5um.
The aperture error of described multimode lock pin below the 0.3um, external diameter trueness error scope is between ± the 1.0um.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the utility model fiber stub adopts metal plating to form, compare with traditional ceramic lock pin based on zirconium oxide, simple for production, flexibly, precision is higher, and cost is lower, can be mass-produced, and be particularly suitable for making all kinds of special-shaped optical fibre lock pins.

Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:
Fig. 1 is the fiber alignment synoptic diagram, and it comprises sleeve pipe 1, is arranged on two lock pins 2 in the sleeve pipe 1, and lock pin 2 centers have the hole, simultaneously, keep certain clearance between two lock pins 2,, optical fiber 3 is inserted respectively dock in the hole of lock pin 2 and get final product when carrying out optical fiber when connecting.
The utility model lock pin adopts metal plating to form, so-called electroforming be the grand master pattern of making by required form in advance as negative electrode, the usefulness electroforming material is together put into the metal salt solution identical with anode material as anode, passes to direct current.Under electrolytic action, master surface deposits the metal plating layer gradually, takes out from solution after reaching required thickness, and electroformed layer is separated with grand master pattern, just obtains and the corresponding metal duplicate of grand master pattern shape.Lock pin adopts the nickel electroforming to form in the present embodiment, as shown in Figure 2, wherein, is labeled as 10 and is metallic nickel; 20 is stainless steel core wire; 30 is that nickel coating promptly is the metallic nickel blank of cored; 50 for being contained in the electroforming solution in the electroplating bath.Concrete manufacturing process is as follows: will be connected to negative electrode through surface flatness processing SUS stainless steel core wire later, metallic nickel is connected to power anode, soluble anode is all adopted in conventional nickel plating, adopt the titanium basket as anode, interior dress nickel ball, (thickness can reach 0.7～3.0mm) to carry out plated metal nickel then, cut off after electroforming is intact, remove the SUS heart yearn of central part again, form blank of cored, according to required size and shape the metallic nickel blank of cored is carried out later stage finished product processing at last, comprise external diameter is carried out rough lapping; Both ends of the surface are ground; End face processing; Right alignment processing; The finishing of external diameter cylinder; Anti-dandruff; Clean; Geometric parameter and precision to lock pin detect etc.
The lock pin that adopts electroforming to form, its inside surface is smooth and bright like a mirror, need not to do the processing of inside surface smoothness again.And the thickness of the stainless guiding principle heart yearn of SUS can be selected arbitrarily, by to electric current, voltage, conduction time length the thickness of adjusting may command lock pin.The shape of core body changes with the alteration of form of the heart yearn of central part.Therefore, even if the core body of various special-shaped structures also will be made at an easy rate.
The concentricity in the utility model lock pin dimensional accuracy, external diameter precision, hole etc. can reach micron-sized machining precision.And be divided into two kinds of single-mode fiber lock pin and multimode optical fiber lock pins because of different machining precisioies.The requirement on machining accuracy of two kinds of lock pins is as shown in the table:
| The single-mode fiber lock pin | The multimode optical fiber lock pin | |
| External diameter | ≤±0.5μm | ≤±1.0μm |
| The aperture | ≤+0.07μm | ≤+0.3μm |
Above-mentioned technical conceive of the present utility model and characteristics are illustrated; its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
