Abstract
The utility model proposes a kind of many with reference to ceramic insertion core, ferrule body, endoporus, first round platform and the second round platform, endoporus is arranged on the center of ferrule body, one termination of ferrule body is provided with the first round platform and the second round platform, in use, two ceramic insertion cores being provided with optical fiber are under the effect of external force, positioned by adapter sleeve, realize the docking of optical fiber, because ceramic insertion core has newly established single order round platform, when locating, one-level that object of reference is many, like this, reduce the lateral runout between two optical fiber, reduce insertion loss, improve coupling efficiency during fiber alignment.
Description
Technical field
The utility model belongs to fiber optic communication field, is specifically related to a kind of many with reference to ceramic insertion core.
Background technology
Ceramic insertion core is the one of fiber stub, it is the ceramic cylinder tubule fired with zirconium dioxide, quality is hard, the pure white exquisiteness of color and luster, its finished product accuracy reaches submicron order, the most frequently used in Networks of Fiber Communications, that quantity is maximum precision positioning parts, usually for the manufacture of the joints of optical fibre, the optically-coupled etc. of device; The main effect of ceramic insertion core be realize optical fiber physics docking, usually with porcelain bushing with the use of; The coupled end of existing ceramic insertion core is only provided with single order round platform, and during two lock pin couplings, object of reference is less, and coupling efficiency is low, and insertion loss is larger.
Utility model content
The utility model proposes a kind of many with reference to ceramic insertion core, when solving ceramic insertion core docking in prior art, coupling efficiency is low, the problem that insertion loss is large.
The technical solution of the utility model is achieved in that
Many with reference to ceramic insertion core, comprise: ferrule body, endoporus, the first round platform and the second round platform, endoporus is arranged on the center of ferrule body, one termination of ferrule body is provided with the first round platform and the second round platform, the diameter of going to the bottom of the first round platform is 2.499 ± 0.0005mm, upper base diameter is 2.299 ± 0.0005mm, the diameter of going to the bottom of the second round platform is 2.2999 ± 0.0005mm, upper base diameter is 2.1 ± 0.1mm, the upper base of the first round platform is going to the bottom of the second round platform, and the first round platform and the second round platform are integrated design.
Principle of the present utility model and beneficial effect are:
The utility model has set up again single order round platform in the coupled end of ceramic insertion core, like this when the physics docking realizing optical fiber, just can increase the reference of new one-level, and then, reduce insertion loss, improve the coupling efficiency of optical fiber.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is front view of the present utility model;
Fig. 2 is cut-open view of the present utility model;
Fig. 3 is the utility model coupling schematic diagram.
In figure: 1, ferrule body; 2, endoporus; 3, the first round platform; 4, the second round platform; 5, adapter sleeve.
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 to 3, the one that the utility model proposes is many with reference to ceramic insertion core, comprise: ferrule body 1, endoporus 2, first round platform 3 and the second round platform 4, endoporus 2 is arranged on the center of ferrule body 1, one termination of ferrule body 1 is provided with the first round platform 3 and the second round platform 4, the diameter of going to the bottom of the first round platform 3 is 2.499 ± 0.0005mm, upper base diameter is 2.299 ± 0.0005mm, the diameter of going to the bottom of the second round platform 4 is 2.2999 ± 0.0005mm, upper base diameter is 2.1 ± 0.1mm, the upper base of the first round platform 3 is going to the bottom of the second round platform 4, first round platform 3 and the second round platform 4 are integrated design.
In use, two ceramic insertion cores being provided with optical fiber are under the effect of external force, positioned by adapter sleeve 5, realize the docking of optical fiber, because ceramic insertion core has newly established single order round platform, when locating, one-level that object of reference is many, like this, reduces the lateral runout between two optical fiber, reduce insertion loss, improve coupling efficiency during fiber alignment.
The foregoing is 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.
