Abstract
The utility model relates to a zirconia ceramic sleeve pipe, which is used for optical fiber connectors having no source and active optical fiber connectors. The pipe wall of the sleeve pipe is respectively provided with an opening 6-1 or an inner groove 6-2, the opening and the inner groove are both parallel to the axial line of the sleeve pipe, and the inner wall and the outer wall of two end surfaces of the sleeve pipe are provided with chamferings 6-3. The sleeve pipe has the advantages that optical fiber transmission speed is enhanced, loss is reduced, life time is long, temperature expansion coefficient is small, physical character is stable, and the utility model can be widely used for optical fiber connectors and can satisfy the connection of various active and passive devices and various circuit board chips in optical fiber communication. The design of the opening or the inner groove can ensure the proper inserting and pulling force between the sleeve pipe and an inserting core and can be favorable for insertion and pulling.
Description
The utility model discloses the lock pin sleeve pipe in a kind of precision component that is used for the joints of optical fibre, the especially connector.
The joints of optical fibre use very extensive in optical fiber telecommunications system.With the transmission system of optical fiber as transmission medium, mainly by optical sender, photoreceiver, the optical cable and the joints of optical fibre are formed.The joints of optical fibre not only are used for optical fiber and connect, and optical cable connects, but also can be used for dress laser diode in the optical fiber communication, light emitting diode, laser instrument, the active connection of elements such as photoelectric detector also is applicable to being connected of amplifier-chain plate and chip in the active device.The joints of optical fibre are the indispensable accurate device of each link in optical communication system.Its core part is a sleeve pipe, and lock pin is housed in the sleeve pipe, and sleeve pipe is used to make two lock pins to realize mechanical registeration.Yet, the sleeve pipe of at present general metal material processing, its complex manufacturing, long processing time, corrosion resistance is relatively poor, the thermal expansivity instability, in the use, metal material repeatedly plug meeting produces loss, is unsuitable for the needs of modern optical fiber communication develop rapidly.
The purpose of this utility model provides a kind ofly can satisfy that the temperature expansion coefficient that each active device of optical fiber communication, passive device and various circuit board and chip connector use is little, the zirconia ceramic sleeve pipe of stable physical property and long service life.
Be used for having an opening (6-1) on the described cover tube wall of passive fiber connector, be used for rising in the described sleeve pipe of Active Optical Fiber connector an inside groove (6-2) is arranged, opening (6-1) and inside groove (6-2) all are parallel to casing axis; Sleeve pipe both ends of the surface inside and outside wall has all played chamfering (6-3).The aforementioned described cover pipe range 11.4 ± 0.1mm that is used for the passive fiber connector, internal diameter Φ 2.49 ± 0.001mm, external diameter Φ 3.2 ± 0.002mm; The described cover pipe range 9.3 ± 0.1mm that is used for the Active Optical Fiber connector, internal diameter Φ 2.5 ± 0.001mm, external diameter Φ 3.6 ± 0.002mm.Described sleeve pipe both ends of the surface chamfering that inside and outside wall rises (6-3) is respectively R0.2 and R0.1.
Described zirconia ceramic sleeve pipe has improved the light transmission speed, has reduced loss, and is all stable and reliable for performance in any environment use, long service life, and temperature expansion coefficient is minimum, stable physical property, it is unimpeded to have guaranteed that photosignal transmits.Can be used in the joints of optical fibre, satisfy each active device of optical fiber communication, the usefulness of passive device, various circuit board and chip connections, opening or inside groove on the cover tube wall can guarantee contact engaging and separating force suitable between sleeve pipe and lock pin, are beneficial to smooth plug.
Fig. 1-the 1st is used for sleeve pipe front view described in the Active Optical Fiber connector.
Fig. 1-2 is used for sleeve pipe left view described in the Active Optical Fiber connector.
Fig. 2-the 1st is used for sleeve pipe front view described in the passive fiber connector.
Fig. 2-the 2nd is used for sleeve pipe left view described in the passive fiber connector.
Fig. 3 is that described sleeve pipe is assemblied in the general assembly drawing on the joints of optical fibre.
Among the figure: 1,2 directly overlap for little six grooves for ceramic insertion core seat, 9 for lock pin, 8 for porcelain bushing, 7 for pagoda cover, 6 for intermediate sleeve, 5 for screw, 4,10 be the decorative pattern overcoat for metal tail cover, 16 for batting ring, 15 for fork port axis, 14 for back-up ring, 13 for jump ring, 12 for stage clip, 11 for cubic flange, 3.6-1 is the opening on the sleeve pipe, and 6-2 is the inside groove on the sleeve pipe, and 6-3 is the chamfering on the sleeve pipe.
The open type sleeve pipes of using in the optical fiber passive connector more.Opening 0.5mm is for there being suitable elasticity to design in the sleeve pipe use, to guarantee suitable contact engaging and separating force between sleeve pipe and lock pin.The internal groove sleeve pipe is used for the Active Optical Fiber connector more, and the inside groove inside surface roughness is very high, and impermeability is fine between lock pin and sleeve pipe, and the ventilative lock pin that just can make of must slotting is suitably plugging under the contact engaging and separating force smoothly.Making this sleeve pipe is to select Φ 0.3 μ m zirconia ceramic powder for use, makes blank through the high-pressure sinter forming process and processes the high surfaceness of high precision through special interior round Ginding process again, and the endoporus of high conformity and cylindrical satisfy request for utilization.Make zirconia ceramic that high bending strength and fracture toughness be arranged, and machining property preferably, can adopt and repeatedly refine mud, big pressure forming, high pressure concentrates the technology that adds, improves the volume density of material.General electrotechnical ceramics volume density maximal pressure 3.8g/cm
3, and the application's zirconia ceramic density requirements reaches 6.04g/cm
3More than, so that pottery is inner trickle closely, never allows the bubble cavity and occur.Be equipped with the science roasting technique again, its structure is fully transformed, thereby guaranteed the superperformance of zirconia ceramic.
End properties is as follows:
Bending strength 〉=1150Mpa
Fracture toughness 〉=5.0Mpa
Hardness 〉=HV1200
Linear expansion coefficient 11-11.5 * 10
-6C
-1/ 1150 ℃
Density 6.04g/cm
3
For the precision optical machinery processing of superhard material, complex process, the frock dimensional standard is high;
Endoporus grinds uses the cone grinding rod, and long 2m, awl long 1.6m, largest diameter 2.49mm are 0.1 through grinding inner bore surface roughness, and the endoporus precision reaches submicron order.End face, chamfering brush bonding abrasive sand with the special-purpose linear emery wheel disc brush of self-control, and chamfering R0.1 is good excessively slick and sly, guarantee that lock pin enters collar aperture smoothly, avoid flex point occurring in the junction.
