Abstract
The utility model relates to an adaptor sleeve for butting of fiber core inserts, which comprises a hole for accommodating the fiber core inserts, wherein a slot communicated with the hole is arranged on the side wall of the sleeve, and the sleeve is electroformed by a metal material. Compared with the traditional zirconia ceramic core insert, the utility model has simple and flexible manufacture, higher accuracy, low cost, mass production and great promotion and application prospect.
Description
Technical field
The utility model relates to a kind of fiber alignment adapter, relates in particular to the sleeve pipe on the adapter.
Background technology
Being used for the adapter sleeves of fiber stub butt joint, is that starting material are made mostly with the zirconia ceramics.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.With the supporting adapter porcelain bushing of ceramic insertion core, by the requirement (500 to 1000 times) that the joints of optical fibre repeatedly plug, porcelain bushing also must have the corresponding plug life-span.
Simultaneously because sleeve pipe needs fluting, even the wearing and tearing of fluting porcelain bushing are ignored, but its breakage then is the principal element that influences the life-span.Because pottery is hard brittle material, can't produces the plastic yield stress raisers load that sleeve pipe is subjected to when offsetting plug, thereby cause casing damage.For with the supporting internal diameter of LC, MU type optical connector be the porcelain bushing of 1.25mm, cracky more more because casing wall thickness is too thin.In addition, for multicore lock pin and abnormal shape (as 1.25mm and 2.5mm lock pin conversion sleeve pipe) lock pin element, stupalith and manufacture craft thereof are powerless especially.
The utility model content
The utility model purpose is exactly to propose a kind of simple for production, flexible and higher sleeve pipe 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 adapter sleeves that is used for the fiber stub butt joint, it has the hole that is used for the receiving optical fiber lock pin, and offers the fluting that is connected with the hole on described sleeve pipe sidewall, and described sleeve pipe 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 precision of described sleeve pipe aperture and external diameter is a micron order.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the sleeve pipe on the utility model fiber adapter 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, have bigger popularizing application prospect.

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.
Shown in Figure 2 is the perspective view of sleeve pipe, this sleeve pipe is that diameter is 1.25mm and 2.5mm metallic nickel lock pin conversion sleeve pipe, certainly, and according to the needs that use, sleeve pipe can also be made into the cylindrical of different-diameter size, as 1.25mm and 2.5mm sleeve pipe commonly used.Offer fluting 11 on the sleeve pipe 1.
The utility model sleeve pipe adopts metal plating to form, and in the present embodiment, adopts metallic nickel to carry out electroforming, as shown in Figure 3, wherein, is labeled as 10 and is metallic nickel; 20 is stainless steel core wire; 30 is that nickel coating promptly is a metallic nickel sleeve pipe blank; 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 sleeve pipe 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.Therefore, can realize by the method for electroforming for special-shaped sleeve pipe (as 1.25mm and 2.5mm lock pin conversion sleeve pipe).
The sleeve pipe that the utility model provides a kind of metal plating to form, it can reach micron-sized machining precision.Compare with traditional ceramic lock pin based on zirconium oxide, its method for making is easy, flexibly, is particularly suitable for making all kinds of special-shaped optical fibre lock pins and sleeve pipe.The reason that adopts metallic nickel to make fiber stub and sleeve pipe is that price is lower because nickel resources is abundant; The good corrosion resistance of nickel, not oxidated in air; It is a kind of electroplating metal material commonly used, and the technology of electronickelling is also quite ripe.
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.
