Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1 ~ 2, a kind of embodiment of a kind of ceramic ferrule tailstock of the utility model, comprise: columned tailstock main body 1, convergence piece 2, tailstock main body 1 internal axis position is provided with the first through hole 3 of coaxial communication and is also provided with the conical bore of a transition between the second through hole 4, first through hole 3 and the second through hole 4.First through hole 3 inside is provided with convergence piece 2, and tailstock main body 1 and the first through hole 3 end are by fillet 5 transition.Tailstock main body 1 is provided with ring flange, stop part, optical fiber installation portion successively from head end to end, the external diameter of these three parts reduces successively, first through hole 3 is arranged on ring flange and stop part is inner, run through ring flange but do not run through stop part, second through hole has then run through optical fiber installation portion but has not run through stop part, and the first through hole 3 diameter is greater than the second through hole 4 diameter.The Main Function of ring flange, stop part, optical fiber installation portion is for being connected with the assembly of outside.
Convergence piece 2 is cylindric plastics convergence piece, and the plastics of employing are ABS plastic, and convergence piece 2 shaft core position is provided with third through-hole 24, and head end is provided with radially outward outstanding flange 21, and after installing, the terminal surface of flange 21 contacts with the head end face of tailstock main body 1.Third through-hole 24 head end is by the body transition of the first fillet 22 with convergence piece 2, and the edge of convergence piece 2 rear end is provided with the second fillet 23.Be interference fit between convergence piece 2 and the first through hole 3.
Flange 21 is collar flange, and its external diameter is greater than the first through hole 3 diameter, and third through-hole 24 diameter is less than the first through hole 3 diameter, is greater than the second through hole 4 diameter.The external diameter of flange 21 is identical with the diameter of flange plate structure upper groove, can not be greater than the diameter of groove, otherwise can affect further assembling.
Convergence piece 2 is integrated, and that is flange 21 is fixedly installed on convergence piece end.First convergence piece is loaded the first through hole during installation inner.Optical fiber first successively through other external modules, then inserts from tailstock main body 1 end, successively through the convergence piece 2 in the second through hole 4, first through hole 3 and the first through hole 3.Second through hole 4 diameter is slightly larger than fibre external diameters, and the first through hole 3 diameter is greater than the second through hole 4 diameter, and optical fiber is not easy to be stuck in installation process.When optical fiber is through after tailstock, then by optical fiber front end through ceramic insertion core 6, and then be fixed in ceramic insertion core 6.Subsequently, vertical for ceramic insertion core 6 is arranged on tailstock, has namely been arranged on convergence piece 2 inner.Flange 21 external diameter is greater than the first through hole 3, and this makes convergence piece 2 can better fix with tailstock main body 1 in installation process.And because convergence piece 2 and tailstock main body 1 are interference fit, the second fillet 23 of end is conducive to the installation of convergence piece 2; Can produce certain deformation after convergence piece 2 installs, be unfavorable for the installation of ceramic insertion core, now, the first fillet 22 of third through-hole 24 head end just plays certain guide effect to the installation of ceramic insertion core, makes the installation of ceramic insertion core become easy.In order to not affect the performance of ceramic insertion core 6, the diameter dimension of the part of ceramic insertion core 6 and convergence piece 2 being assembled reduces.
When ceramic insertion core 6 is extracted by needs, only the position at convergence piece 2 place need be heated to uniform temperature, convergence piece 2 is plastic material, convergence piece 2 deliquescing when being heated to this temperature, but not with ceramic insertion core 6 and tailstock main body 1 adhesion, now just ceramic insertion core 6 can be easy to extract.After ceramic insertion core 6 is extracted, then the convergence piece 2 of having softened is taken out, after tailstock cooling, new convergence piece is installed and just can carries out the installation of new ceramic insertion core.After ceramic insertion core 6 and tailstock fix, coordinate assembly connection by the ring flange in tailstock main body 1 with other external modules, and then obtain the complete joints of optical fibre.
Due to optical fiber install until in the process fixing by matching fluid can and tailstock edge contact, if the first through hole 2 is right angle with the edge of tailstock main body 1 transition, can rub with the fibre core outside surface of optical fiber, the fibre core of optical fiber very thin, friction can cause the wear and rupture of fibre core; And the structure at right angle can not be held more for the matching fluid of fixed fiber, be unfavorable for the fixing of optical fiber.Tailstock end rounding, then can avoid the generation of this wear problem, also can hold more matching fluid, avoids optical fiber to fix unsteady problem.When finished product in use, if optical fiber bends, the power be applied on optical fiber at the fillet of end is also unlikely to allow optical fiber rupture.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
