Abstract
The utility model relates to a zirconia porcelain bushing including a phi 1.25mm bushing 1, a phi 2.5mm bushing 2 and a bushing opening 3. The wall length, the inner diameter and the outer diameter of the bushing 1 are 3.19 to3.21mm, phi 1.23 to 1.27mm and phi 1.74 to 1.78mm respectively. The wall length, the inner diameter and the outer diameter of the bushing 2 are 5.79 to 5.81mm, phi 2.48 to 2.52mm and phi 3.18 to 3.22mm respectively. The zirconia porcelain bushing improves light-transmitting speed, reduces wasting, solves the restriction of the switching specification, has long service life, small temperature expanding coefficient and steady physics performance, and ensures smoothly photoelectricity signal transferring. The opening on the wall of the bushing ensures the insertion force between an inserting core and the opening, thereby being convenient for push and pull.
Description
Technical field
The utility model relates to a kind of zirconia ceramic sleeve, and relating in particular to a kind of 1.25MM changes 2.5MM porcelain bushing.
Background technology
Must carry out a large amount of optical fiber couplings in optical-fibre communications and the fiber optic network transmission, and the coupling of optical fiber each time all to be used optical fiber connector.Being connected in the existing fiber optic network transmission like this is that number is remembered with hundred million.Telecommunications, Netcom, move, UNICOM, Tie Tong, electricity are logical, public security, army and the city of magnanimity and these products of use that industrial and mining enterprises all can be intensive.
Because the optical interface of fiber plants such as Optical Distribution Frame, the network switching equipment, fiber optic, shunt is often all different, so the switching specification in the practical application will be restricted, can only in the identical specification of internal diameter, realize switching, for example switching of the switching of FC and ST, ST and SC or the like.But it is just cumbersome to run into the different switching operating mode of internal diameter, and for example: the FC connector need change LC wire jumper+LC adapter+LC wire jumper with FC wire jumper+FC adapter+FC with being connected of LC connector, and so loaded down with trivial details application model causes very inconvenience of practical application.
Summary of the invention
Deficiency at the prior art existence, the purpose of this utility model is to provide: because the utility model zirconia ceramic sleeve 1.25MM changes the appearance of 2.5MM porcelain bushing, can simplify application model in the past, the optical fiber switching adapter that only need add a 1.25MM commentaries on classics 2.5MM between the tie jumper that two couplings differ is just passable, such new technology has been filled up the blank of existing market, and leading in the world.
Have the ability to produce a company that has only Japan that 1.25MM changes 2.5MM porcelain bushing at present.This company has monopolized the world market.At present the production unit cost of international market is at 40USD, and our present actual manufacturing cost can also descend if we can produce cost in batches below 80 yuan.The market outlook of product are extremely optimistic.
Goal of the invention of the present utility model is achieved by the following technical solution:
A kind of zirconia ceramic sleeve has an opening on the described cover tube wall, opening is parallel to casing axis, sleeve pipe 1 wall of tie jumper long 3.2 ± 0.01MM, internal diameter 1.25 ± 0.02MM, and external diameter is 1.76 ± 0.02MM; Long 5.8 ± the 0.01MM of another sleeve pipe 2 walls of tie jumper, internal diameter 2.5 ± 0.02MM, external diameter 3.2 ± 0.02MM.
The stock moulding of general zirconia nano-ceramic powder is all finished with isostatic pressing technology, but because the static pressure such as grade is difficult to static pressure such as enforcement for the non-standard specification stock, assists moulding such as blank such as static pressure such as grade so we have designed a large amount of composite dies.
The key of optical fiber centering is a concentricity, and the circle of two different inner diameters reaches identical concentricity on same axle center have great difficulty, and concentricity reaches in the 1.0MU.Our independent design special centreless grinding and auxiliary projection processing to guarantee the control of concentricity.
The utility model zirconia ceramic sleeve reaches international requirement:
One: 1.2499 ± 0.001MM of interior circular diameter
Two: 2.499 ± 0.001MM of interior circular diameter
Machining precision has directly determined the technical stability of product, and single frock can't reach requirement to the processing of profiled piece, and we are for reaching accuracy requirement, also autonomous Design a large amount of frock to reach accuracy requirement.

Fig. 2 is the utility model zirconia ceramic sleeve vertical view.
The number in the figure explanation:
1- 1.25MM sleeve pipe
2- 2.5MM sleeve pipe
The 3-ferrule openings
Embodiment
How further specify the utility model below in conjunction with accompanying drawing 1, Fig. 2 realizes.
Embodiment
As shown in Figure 1 and Figure 2, zirconia ceramic sleeve comprises the sleeve pipe 1 of 1.25MM, sleeve pipe 2 and the ferrule openings 3 of 2.5MM, described sleeve pipe 1 wall long 3.2 ± 0.01MM, internal diameter 1.25 ± 0.02MM, and external diameter is 1.76 ± 0.02MM; Long 5.8 ± the 0.01MM of sleeve pipe 2 walls, internal diameter 2.5 ± 0.02MM, external diameter 3.2 ± 0.02MM.
Described zirconia ceramic sleeve, improved the light transfer rate, reduced loss, solved the restriction of switching specification, long service life, temperature expansion coefficient is little, stable physical property, it is unimpeded to have guaranteed that photosignal transmits, the opening on the cover tube wall can guarantee and lock pin between contact engaging and separating force, be convenient to smooth plug.
