Description
Technical field
The present invention relates to fiber optic communication field, and in particular to a kind of more with reference to ceramic insertion core.
Background technology
Ceramic insertion core is one kind of fiber stub, is that the ceramic cylinder tubule formed is fired with zirconium dioxide, and quality is hard,
The pure white exquisiteness of color and luster, its finished product accuracy reach submicron order, are the most frequently used, precision positionings that quantity is most in Networks of Fiber Communications
Part, it is frequently utilized for the manufactures of the joints of optical fibre, the optical coupling etc. of device；The main effect of ceramic insertion core is to realize the thing of optical fiber
Reason docking, is usually used cooperatively with porcelain bushing；The coupled end of existing ceramic insertion core is only provided with a round platform, when two lock pins couple
Object of reference is less, and coupling efficiency is low, and insertion loss is larger.
Therefore, a kind of ceramic insertion core of more reference planes of social active demand, there are multiple reference planes in coupling, to reduce
Lateral run-out between two optical fiber, insertion loss is reduced, improve coupling efficiency during fiber alignment.
In view of drawbacks described above, creator of the present invention obtains this creation finally by prolonged research and practice.
The content of the invention
It is an object of the present invention to provide a kind of more reference plane ceramic insertion cores, to overcome above-mentioned technological deficiency.
To achieve the above object, the technical solution adopted by the present invention is, there is provided a kind of more reference plane ceramic insertion cores, including
First ceramic insertion core and the second ceramic insertion core, wherein,
The first described ceramic insertion core includes the first ferrule body, the first endoporus and circular bosses, and first endoporus is set
Put at the center of first ferrule body, the circular bosses are arranged at an end head of first ferrule body；
The second described ceramic insertion core includes the second ferrule body, the second endoporus and circle recess, second endoporus and set
Put and be arranged at an end head of second ferrule body in the center of second ferrule body, the round recess；
And described circular bosses and described circle notching dimension match.
The boss disc of the circular bosses evagination is identical with the recess disc diameter of the round recess.
The face of concaving of the convex inclined plane of the circular bosses circumference side and the round recess has the taper of formed objects.
Preferably, a diameter of 2.299 ± 0.0005mm of the boss disc, the diameter of the recess disc are also
2.299±0.0005mm。
Preferably, the taper size of the convex inclined plane is 45 ± 0.5 degree, the taper size in the face that concaves is 45 ± 0.5
Degree.
Compared with the prior art the beneficial effects of the present invention are：
Because first ceramic insertion core is provided with circular bosses, second ceramic insertion core is provided with circle recess, positioned
When, not only between the boss disc and the recess disc formed a reference plane, the convex inclined plane with it is described concave face it
Between simultaneously mutually formed a reference plane, mutually nested connection.So, the lateral run-out between two optical fiber is reduced, is reduced
Insertion loss, improves coupling efficiency during fiber alignment.

Embodiment
Below, it will describe embodiments of the present invention with reference to the accompanying drawings.In embodiments, the part of same configuration uses
Identical reference and omit description.
Refering to Fig. 1, for the more reference plane ceramic insertion core basic structure schematic diagrams of the present invention；With reference to Fig. 2, for the more references of the present invention
The cross section structure diagram of the ceramic insertion core of face ceramic insertion core first；And Fig. 3, made pottery for the more reference plane ceramic insertion cores second of the present invention
The cross section structure diagram of porcelain lock pin.
As shown in FIG., described more reference plane ceramic insertion cores include the first ceramic insertion core 1 and the second ceramic insertion core 2, its
In,
The first described ceramic insertion core 1 includes the first ferrule body 10, the first endoporus 3 and circular bosses 4, and described first
Endoporus 3 is arranged on the center of first ferrule body 10, and to wear optical fiber 7, the circular bosses 4 are arranged at described first and inserted
One end head of core main body 10；
The second described ceramic insertion core 2 includes the second ferrule body 20, the second endoporus 5 and justifies recess 6, and described second
Endoporus 5 is arranged on the center of second ferrule body 20, and to wear optical fiber 7, the round recess 6 is arranged at described second and inserted
One end head of core main body 20；
And described circular bosses 4 and the described matching size of circle recess 6.
Specifically, the boss disc 41 of the evagination of circular bosses 4 is identical with the diameter of recess disc 61 of the round recess 6；
The face 62 that concaves of the convex inclined plane 42 of the circumference side of circular bosses 4 and the round recess 6 has the taper of formed objects so that two
Person seamless can be in contact, and obtain the effect of reference plane each other.
In the present embodiment, a diameter of 2.299 ± 0.0005mm of the boss disc 41, the diameter of the recess disc 61
