Abstract
The utility model discloses an optical fiber connector comprising an inserting core assembly, a connecting sleeve, a fixing member, and a threaded sleeve. The connecting sleeve comprises a head portion and a tail portion. A plurality of clamping blocks are disposed on the outer side of the head portion. The fixing member is equipped with a hollow portion used for passing through the connecting sleeve. A plurality of clamping slots corresponding to the clamping blocks are disposed on the inner side of the hollow portion. The clamping blocks on the connecting sleeve are clamped to the clamping slots on the fixing member, and then the tail portion of the connecting sleeve is connected with the threaded sleeve. Therefore, the fixing member does not generate displacement relative to the connecting sleeve in horizontal and vertical direction and signal loss at a joint between a plastic optical fiber and other optical fibers is further reduced to a certain extent.
Description
Technical field
The utility model relates to the joints of optical fibre, belongs to the joints of optical fibre technical field on the optic communication device.
Background technology
Along with the fast development of mechanics of communication, the usable range of optical fiber is more and more wider, and the joints of optical fibre are as the maximum no light source device of the use amount of fibre system, therefore also becomes one of the primary study object in this field.
In order to reduce the loss of signal between the optical fiber, need reduce rocking relatively of optical fiber junction as far as possible, for this reason, technical solutions of the utility model will provide the connector of a kind of stable connection plastic optical fiber and other optical fiber.
The utility model content
The purpose of this utility model provide a kind of simple in structure, connect the stable joints of optical fibre.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of joints of optical fibre, comprise ferrule assembly, adapter sleeve, fixture and swivel nut, described adapter sleeve comprises cylindrical head and afterbody, described head diameter is greater than tail diameter, described afterbody passes the through hole of the centre that is positioned at fixture, described tail surface is provided with external thread, is provided with internal thread in the described swivel nut, and described fixture is held between the head and swivel nut of adapter sleeve.
In prioritization scheme of the present utility model, the described head outside is provided with some blocked blocks, is provided with the draw-in groove corresponding with blocked block around the through hole of described fixture.
In order to guarantee the friction force between blocked block and the draw-in groove, the setting of blocked block downside is skewed, and described draw-in groove bottom surface also is arranged to skewed.
Further, the number of described blocked block is 2～6, is evenly distributed in the outside of adapter sleeve head.
Further, described ferrule assembly comprises ceramic insertion core and lock pin tail cover.
Compared with prior art, the beneficial effects of the utility model are:
The utility model arranges external thread by the tail surface at adapter sleeve, is provided with internal thread simultaneously in swivel nut, by the turn swivel nut fixture is held between the head and swivel nut of adapter sleeve, the utlity model has advantage simple in structure, that connection is stable.

Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model plastic optical fibre connector is further elaborated.
To shown in Figure 6, be a preferred embodiment of the present utility model as Fig. 1.
The joints of optical fibre 10 comprises ferrule assembly 1, adapter sleeve 2, fixture 3 and swivel nut 4 in the present embodiment.
As shown in Figure 3, described ferrule assembly 1 comprises ceramic insertion core 11 and lock pin tailstock 12, and lock pin tailstock 12 is enclosed within on the ceramic insertion core 11, and can be fixed on adapter sleeve 2 inboards.
As shown in Figure 4, be provided with the space of passing for ceramic insertion core 11 in the middle of the described adapter sleeve 2, adapter sleeve 2 comprises cylindrical head 21 and afterbody 23.Head 21 is roughly rounded, and several blocked blocks 22 are arranged in its outer, and the downside of blocked block 22 is skewed, and 4 blocked blocks are arranged in the present embodiment, is evenly distributed in the head outside; The number of blocked block 22 can be set to other numbers according to actual conditions, as 2～6; The afterbody 23 of adapter sleeve is annular, and there is external thread in afterbody 23 outsides.
As shown in Figure 5, described fixture 3 roughly is square, and the centre is provided with the through hole 32 that passes for adapter sleeve 2, the head 21 less than adapter sleeve of through hole 32, but be slightly larger than the afterbody 23 of adapter sleeve; Through hole 32 edges are provided with the draw-in groove 31 corresponding with blocked block 33, its number is identical with blocked block 33 on the adapter sleeve 2, draw-in groove 31 bottom surfaces are skewed, it is in that cooperate when contacting with blocked block 22 can be at vertical and horizontal direction force, thereby fixture is stuck in more securely between the head 21 and swivel nut 4 of adapter sleeve.
As shown in Figure 6, described swivel nut 4 is annular, is used for connecting other optical fiber, and the inboard of swivel nut 4 is provided with internal thread 41, cooperates with the external thread of adapter sleeve afterbody 23 to connect to be fixed on the adapter sleeve 2.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of submitting to.
