Abstract
The utility model provides a kind of optical fiber beam expansion type lens subassembly, solves 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, and bonding lens are placed in porcelain bushing together with gasket, is adhesively fixed between gasket and porcelain bushing.The lens subassembly of the utility model 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 utility model belongs to technical field of optical fiber communication, is related to a kind of optical fiber beam expansion type lens subassembly.
Background technique
Existing optical fiber connector is docked by the way of optical fiber contact body end face-end face contact, realizes optical 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
Demand needs a kind of environmental resistance that optical fiber contact can be improved and the device of mechanical life.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provide a kind of environmental resistance that optical fiber contact can be improved with
And the optical fiber beam expansion type lens subassembly of mechanical life.
In order to achieve the above object, the utility model adopts the following technical solution: a kind of optical fiber beam expansion type lens subassembly, packet
Lens, gasket and porcelain bushing are included, is adhesively fixed between the lens and gasket, bonding lens are placed in pottery together with gasket
In porcelain bushing shell, it is adhesively fixed between gasket and porcelain bushing.
Further, the lens are spherical shape.
Further, with the disc-shape of 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 utility model has the following beneficial effects:
(1) lens subassembly of the utility model can be matched with optical fiber contact body, and detachable, easy to maintain.
(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 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 contact 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.

Embodiment
- Fig. 4 referring to Fig.1, a kind of optical fiber beam expansion type lens subassembly, including lens 1, gasket 2 and porcelain bushing 3, it is described
It is adhesively fixed between mirror 1 and gasket 2, bonding lens 1 and gasket 2 are placed in together in porcelain bushing 3, gasket 1 and ceramic jacket
It is adhesively fixed between pipe 3.
The lens 1 are spherical shape.
With the disc-shape of through-hole 2-1 centered on the gasket 2.
It is bonded in porcelain bushing 3 for the ease of gasket 2, the porcelain bushing 3 is designed as side with opening
The hollow cylinder shape of 3-1.It is operated in order to facilitate processing with bonding, the shape for the 3-1 that is open is designed as elongate in shape.
In order to be located at the ceramic insertion core of optical fiber contact body preferably 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, by the ceramic insertion core of optical fiber contact body from the insertion of 2 side of gasket of porcelain bushing 3 (referring to Fig. 4), it is ceramic
Lock pin front end face is separated with lens 1 by gasket 2, avoids the end face of ceramic insertion core from contacting 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.
Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments
Explanation be merely used to help understand the method and its core concept of the utility model；Meanwhile for the general technology of this field
Personnel, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.In conclusion
The content of the present specification should not be construed as a limitation of the present invention.
