Abstract
The utility model relates to an adjustable optical fiber bundle connector, which is a device for connecting with optical fiber and optical devices. The adjustable optical fiber beam connector is composed of a clamping seat, an upper and a lower press rings and an optical fiber bundle end head. The upper end of the clamping seat is used for placing the optical devices, and the lower end is an elastic clamping head. The optical fiber bundle end head is fastened by the lower press ring after being inserted; thread connection is adopted among the upper press ring, the lower press ring and the clamping seat so as to conveniently and smartly adjust the longitudinal position of the optical fiber bundle and the horizontal position of the optical devices under the dynamic state, and to realize the optimal coupling. The adjustable optical fiber bundle connector has the characteristics of simple structure, convenient use and demount, etc. The adjustable optical fiber bundle connector not only can be used for connecting the optical fiber bundle and the optical devices, and can also be used for the connection among fiber optic bundles and the connection among optical devices.
Description
The utility model is a kind of coupling arrangement that is used to connect optical fiber and optical device, belongs to technical field of optical fiber sensing.
In Fibre Optical Sensor, fibre bundle need be connected coupling with light source, photodetector or sensing unit etc. usually.In the prior art, usually adopt between optical fiber and the optical device and fixedly connected,, make troubles to the user because of not changing fibre bundle and optical device after the assembling.This method of attachment not only is difficult to adjust but also loosening easily, adopts better simply mechanical fixation method as fibre bundle and optical device.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of fibre bundle flexible jumper that can regulate is provided.
The utility model adopts collet formula connector to realize, it is made up of holder, last lower clamping ring and fibre bundle termination, the upper end of holder is used to place optical device, after light source (devices such as available luminotron or photoelectric tube) put into, it is fastening to use trim ring again, the lower end is a collet, and the insertion fibre bundle uses lower clamping ring fastening behind the termination again.Adopt between last lower clamping ring and holder to be threaded, the elasticity of collet is adjusted by the degree of tightness of rotation lower clamping ring, and the chamfering of lower clamping ring one end is identical with the chamfering of collet.
The utility model compared with prior art has and can dismantle, and is simple in structure, advantage such as easy to use, it not only can fastening fibre bundle and optical device, and can be dynamically adjusting the lengthwise position of fibre bundle and the lateral attitude of optical device down easily, so that realize optimum coupling.It not only can be used for being connected between fibre bundle and optical device, can be used for the connection between the fibre bundle when same structure is made at the holder two ends, has stronger versatility.
Fig. 1 is a structural representation of the present utility model, wherein (1-a) sectional view of locating for A-A '; Fig. 2 is the structural representation of fibre bundle termination, wherein (2-a) sectional view of locating for B-B '.
The utility model can adopt scheme shown in the drawings to realize.As shown in Figure 1, the internal thread of the optical device rest area (2) of holder upper end cooperates φ with the external thread of last trim ring (1)
1Be the interior diameter of optical device rest area, adjust the optical device position, make itself and fibre bundle form best fit.The lower end of holder is collet (3), its end has some conduits that are distributed symmetrically and (among the figure is four, also can six etc.), and the external thread that projection is arranged at the position, termination, screw-internal thread fit with lower clamping ring (4), the termination chamfering matches with the chamfering of lower clamping ring (4) one ends, the internal diameter φ of lower clamping ring (4) chamfered end
3External diameter φ less than collet
2, the external diameter of the internal diameter of collet and fibre bundle termination is for movingly, and (5) are fibre bundle, and (6) are the overcoat of fibre bundle termination.The fibre bundle termination as shown in Figure 2, (7) are the bar shaped register pin of projection, it cooperates with the conduit of collet is movable, and fibre bundle is located, and also can prevent the lateral excursion of fibre bundle.The fibre bundle diameter is generally 1-2mm, needs careful its lengthwise position of adjusting when being coupled with optical device, loosen lower clamping ring after, can make things convenient for the lengthwise position of fibre bundle and dynamically adjustment neatly, when reaching optimum coupling, screw lower clamping ring again.In real work, can determine φ by selected optical device and fibre bundle
1, φ
2And φ
3Size, again by structure fabrication fibre bundle termination shown in Figure 2, and, adopt simple light to transmit and receive device with the end surface grinding polishing, be dynamically adapted to the optimum position.
Claims (5)
1, a kind of adjustable optic fiber bundle connector that is used to connect optical fiber and optical device, form by holder, last lower clamping ring and fibre bundle termination, it is characterized in that the upper end of holder is used to place optical device, and it is fastening to use trim ring, the lower end is a collet, and the insertion fibre bundle uses lower clamping ring fastening behind the termination again.
2, adjustable optic fiber bundle connector according to claim 1 is characterized in that adopting between lower clamping ring and holder being threaded.
3, adjustable optic fiber bundle connector according to claim 1 and 2 is characterized in that the chamfering of collet is identical with the chamfering of lower clamping ring one end.
