Description

Conveniently change optical collimator of tail optical fiber

Technical Field

The utility model relates to the field of optical fiber collimators, in particular to an optical fiber collimator with a tail fiber convenient to replace.

Background

The optical fiber collimator is formed by accurately positioning a tail fiber and a lens. The light source can convert transmission light in an optical fiber into collimated light (parallel light) or couple external parallel light (approximate parallel) into a single-mode optical fiber, and can convert a light beam with a larger divergence angle (small beam waist) into a light beam with a smaller divergence angle (large beam waist) through a lens, so that the light beam is coupled into other optical devices with lower loss; but generally the fixed connection is in the same place through gluing between each subassembly of current light collimator, and the last tail optical fiber of optical collimator is the problem comparatively easy to appear to lead to needing to be changed, but current optical collimator structural design then can't be changed, need give up whole light collimator, not only bring certain degree of difficulty for maintenance change work, also have extravagant phenomenon, consequently, the optical collimator of conveniently changing the tail optical fiber of urgent need solves above-mentioned problem.

The technical scheme adopted by the embodiment of the utility model for solving the technical problem is as follows: the utility model provides a conveniently change optical collimator of tail optical fiber, including the sleeve pipe and set up collimating lens and the tail optical fiber in the sleeve pipe, the tail optical fiber is including connecting and with articulate's optic fibre, the intraductal check ring that is provided with of cover, clamping ring and a plurality of setting are at the intra-annular piece of embracing of check ring, the piece of embracing encloses the synthetic space that is used for the holding to connect, the thickness of embracing the piece reduces from preceding backward gradually, the clamping ring is connected with the front end butt of embracing the piece, the clamping ring is connected with sheathed tube inside wall through adjusting the structure, a position for adjusting the clamping ring in the sleeve pipe.

Further, the adjustment structure is provided as a threaded structure.

Furthermore, a through hole for the joint to pass through is arranged on the pressing ring.

Further, a buffer layer is arranged on one side, abutted against the joint, of the holding piece.

Further, the outside of clamping ring is provided with the adjustment tank.

Further, the number of the holding pieces is 2.

The utility model has the beneficial effects that: an optical fiber collimator convenient for replacing a tail optical fiber comprises a sleeve, and a collimating lens and a tail optical fiber which are arranged in the sleeve, wherein the tail optical fiber comprises a connector and an optical fiber connected with the connector; can conveniently change danger through above-mentioned structure, also can fix the tail optical fiber better simultaneously, accord with the user demand.

The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

FIG. 1 is a simplified diagram of a fiber collimator with easy replacement of pigtails.

Detailed Description

Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

In the description of the present invention, a plurality of means is two or more, and greater than, less than, more than, etc. are understood as excluding the present number, and greater than, less than, etc. are understood as including the present number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, it should be understood that the orientation or positional relationship referred to in the description of the orientation, such as the upper, lower, front, rear, left, right, etc., is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present invention, unless explicitly defined otherwise, the terms "disposed," "mounted," "connected," and the like are to be understood in a broad sense, and for example, may be directly connected or indirectly connected through an intermediate; can be fixedly connected, can also be detachably connected and can also be integrally formed; may be a mechanical connection; either as communication within the two elements or as an interactive relationship of the two elements. The specific meaning of the above-mentioned words in the present invention can be reasonably determined by those skilled in the art in combination with the detailed contents of the technical solutions.

Referring to fig. 1, an optical fiber collimator convenient for replacing a pigtail includes a ferrule 10, and a collimating lens 20 and a pigtail which are disposed in the ferrule 10, wherein the pigtail includes a connector 30 and an optical fiber 40 connected to the connector 30, a stop ring 50, a pressing ring 60 and a plurality of holding pieces 70 disposed in the stop ring 50 are disposed in the ferrule 10, the holding pieces 70 surround a space for accommodating the connector 30, the thickness of the holding pieces 70 is gradually reduced from front to back, the pressing ring 60 abuts against the front end of the holding pieces 70, and the pressing ring 60 is connected to the inner side wall of the ferrule 10 through an adjusting structure for adjusting the position of the pressing ring 60 in the ferrule 10.

In the utility model, during assembly, the collimating lens 20 is installed at one end of the sleeve 10, then the holding sheet 70 is held at the periphery of the joint 30, then the holding sheet 70 and the joint 30 are placed in the stop ring 50, and finally the pressing ring 60 is installed in the sleeve 10, and by adjusting the position of the pressing ring 60 in the sleeve 10, the holding sheet 70 can be pushed to move towards the end with thinner thickness, so as to approach each other under the limit of the stop ring 50 to hold the joint 30 tightly; the tail fiber fixing device can replace the tail fiber, can improve the fixation firmness of the tail fiber, has various advantages, and meets the use requirement.
