Abstract
The present invention provides a kind of optical fiber beam expansion type lens subassembly, solve the problems, such as that the optical fiber contact end face of optical fiber connector in the prior art is easy to pollute, easy damaged.The lens subassembly includes lens, gasket and porcelain bushing, is adhesively fixed between the lens and gasket, is placed in porcelain bushing together with bonding lens and gasket, is adhesively fixed between gasket and porcelain bushing.The lens subassembly of the present invention allows optical fiber contact without physical contact, fibercuts will not occurs because optical fiber protrudes, therefore can be effectively prevented from the damage of optical fiber, it is ensured that while optical signal excellent transmission, the service life of optical fiber contact body also can be improved.
Description
Technical field
The invention belongs to technical field of optical fiber communication, are related to a kind of optical fiber beam expansion type lens subassembly.
Background technology
Existing optical fiber connector is docked by the way of optical fiber contact body end face-end face contact, realizes light path coupling, with
Achieve the purpose that optic path.In long-term use, optical fiber connector exposes fiber end face, leads to optical fiber contact end face
The problem of easy to pollute, easy damaged, the strong influence transmission of optical signal.In order to improve above-mentioned undesirable condition, while adapting to city
Field demand, needs a kind of device for the environmental resistance and mechanical life that optical fiber contact can be improved.
Invention content
In order to solve the above technical problem, the present invention provides a kind of environmental resistances and machine that optical fiber contact can be improved
The optical fiber beam expansion type lens subassembly in tool service life.
In order to achieve the above object, the present invention adopts the following technical scheme that：A kind of optical fiber beam expansion type lens subassembly, including it is saturating
Mirror, gasket and porcelain bushing are adhesively fixed between the lens and gasket, and bonding lens are placed in ceramic jacket together with gasket
In pipe, it is adhesively fixed between gasket and porcelain bushing.
Further, the lens are spherical shape.
Further, the disc-shape with through-hole centered on the gasket.
Further, the porcelain bushing is hollow cylinder shape of the side with opening.
Further, the sum of radius of the thickness D of the gasket and lens is equal to the focal length of lens.
Further, the lens are quartz or glass material.
Compared with prior art, the present invention has the advantages that：
(1) lens subassembly of the invention can be matched with optical fiber contact body, and detachable, easy care.
(2) lens can carry out beam-expanding collimation and convergence to light beam, so as to increase spot diameter, and effectively improve light
The environmental resistance of fine contact and mechanical life.
(3) gasket can play the role of limit, and it is saturating that the ceramic insertion core of optical fiber contact body can be made preferably to be located at
In mirror focal range, while the end face of ceramic insertion core can also be avoided to be contacted with lens and the service life is caused to decline.
(4) since the lens subassembly allows optical fiber contact without physical contact, light will not occur because optical fiber protrudes
Fibre fracture, therefore can be effectively prevented from the damage of optical fiber, it is ensured that while optical signal excellent transmission, optical fiber contact body also can be improved
Service life.

In order to make the ceramic insertion core of optical fiber contact body preferably be located in 1 focal range of lens, the thickness D of the gasket 2
It is equal to the focal length of lens 1 with the sum of the radius of lens.
The lens 1 are quartz or glass material.
In use, the ceramic insertion core of optical fiber contact body is inserted into from 2 side of gasket of porcelain bushing 3 (with reference to Fig. 4), ceramics
Lock pin front end face is separated with lens 1 by gasket 2, and the end face of ceramic insertion core is avoided to be contacted with lens 1 and the service life is caused to decline, it is ensured that
While optical signal excellent transmission, the service life of optical fiber contact body also can be improved.
Principle and implementation of the present invention are described for specific case used herein, and above example is said
The bright method and its core concept for being merely used to help understand the present invention；Meanwhile for those of ordinary skill in the art, foundation
The thought of the present invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification is not
It is interpreted as limitation of the present invention.
