Abstract
The utility model discloses a ceramic sleeve with separate opening at two ends, relating to a ceramic sleeve with opening of a light communication coaxial light insertion apparatus. The technical proposal of the utility model is that the two ends of the ceramic sleeve (A) is respectively provided with a first opening (b) and a second opening (c) for which the two structures are the same. Two openings are respectively arranged at the both ends of the utility model, which can respectively assure the coaxial performance for optical fiber ferrules plugged from different directions, the insertion from two directions do not interfere with the deformation of the ceramic sleeve (A); the structures of the two openings are the same in which the deformation of the ceramic sleeve in two directions are in conformity with each other, therefore, the force loaded on the optical fiber ferrules are identical; the utility model can assure a favorable performance without additionally increasing the processing cost at the same time and can have a wide application prospect due to the high performance-price ratio.
Description
Technical field
The utility model relates to the opening ceramic sleeve in the coaxial plug optical device of a kind of optical communication; Specifically, relate to a kind of two ends ceramic sleeve of opening respectively.
Background technology
At present, the opening ceramic sleeve in the coaxial plug optical device of optical communication all is an opening of opening a perforation on ceramic sleeve generally.As Fig. 1, Fig. 2, Fig. 3, existing opening ceramic sleeve comprises a ceramic sleeve A, and ceramic sleeve A is provided with pass through openings a, utilizes coaxial in guaranteeing to use of the toughness of pottery behind the opening.
But can in use there be serious problem in such opening mode: when specifically using ceramic sleeve A, its two ends are to have fiber stub to insert respectively; When an end had lock pin to insert earlier, ceramic sleeve A deformed, and when other end lock pin inserts again, wanted to make the ceramic sleeve A that has deformed to guarantee that original design performance is just very difficult.
Summary of the invention
In order to overcome existing pass through openings ceramic sleeve deficiency in use, the purpose of this utility model provides a kind of two ends ceramic sleeve of opening respectively.The problem that this sleeve can solve when having fiber stub insert respectively at the ceramic sleeve two ends effectively, design performance changes.
The technical solution adopted in the utility model is:
On ceramic sleeve, from two ends port difference opening, dislocation or alignment in the middle part of ceramic sleeve mutually, thus the two ends that guarantee ceramic sleeve have identical opening tension force in use.
Specifically, as Fig. 4, Fig. 5, Fig. 6, the utility model comprises a ceramic sleeve A, is respectively arranged with the first opening b and the second opening c at the two ends of ceramic sleeve A; The first opening b is identical with the structure of the second opening c.
Principle of work of the present utility model:
There is the ceramic sleeve A of opening to have certain opening tension force, can under the less situation of deformation, guarantees that the fiber stub that inserts in the ceramic sleeve A is coaxial.Coaxial when the utility model can guarantee well that two ends all have fiber stub to insert.When fiber stub when the first opening b inserts, the ceramic sleeve at the first opening b place certain holding tightly card of trying hard to keep that deforms to fiber stub is coaxial, can not allow the ceramic sleeve at the second opening c place produce simultaneously again and be out of shape.Like this, when the second opening c place had fiber stub to insert again, it is coaxial that the ceramic sleeve at the second opening c place just can well be held the card of trying hard to keep tightly to one of fiber stub, and vice versa.
The utlity model has following advantage and good effect:
1. there are two openings at ceramic sleeve A two ends, can be respectively the fiber stub that different directions inserts coaxial assurance is provided, and make the do not interact distortion of ceramic sleeve A of insertion on the both direction.
2. the structure of two openings is identical, makes that the distortion of ceramic sleeve on both direction is consistent, and it also is consistent giving the power of fiber stub.
3. the manufacture craft of ceramic sleeve is very ripe, and the utility model can not increase processing cost extraly when guaranteeing superperformance.
In a word, the utility model is a kind of two ends ceramic sleeves of opening respectively, influencing each other in the time of in the axis light device, avoiding fiber stub to insert well, and therefore ratio of performance to price height has wide application prospect.

Embodiment
Below in conjunction with embodiment the utility model is further specified, as Fig. 4, Fig. 5, Fig. 6:
* the utility model is implemented by aforementioned feature, promptly is respectively arranged with the first opening b and the second opening c at the two ends of ceramic sleeve A; The first opening b is identical with the structure of the second opening c.
* the opening of the first opening b, the second opening c is the axially open along ceramic sleeve A.
* the angular range of the opening direction of the first opening b and the second opening c is at 0～± 180 degree.
* the opening length of the first opening b, the second opening c equals 1/2～2/3 of ceramic sleeve A length.
