Abstract

The utility model discloses a plastic optical fiber connector comprising an inserting core assembly, a connecting sleeve, a fixing member, and a thread 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 grooves 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 grooves on the fixing member and then the tail portion of the connecting sleeve is connected with the thread sleeve. Therefore, the fixing member does not generate displacement relative to the connecting sleeve in horizontal and vertical direction. Further, signal loss in a joint between a plastic optical fiber and another joint is reduced to a certain extent.

Description

Plastic optical fibre connector

Technical field

The utility model relates to connector, and particularly plastic optical fibre connector belongs to the joints of optical fibre technical field on the optic communication device.

Background technology

The joints of optical fibre are the maximum no light source devices of use amount that constitute fibre system, plastic optical fiber (Plastic Optical Fiber, POF) from beginning in 2005 a large amount of productions and use at home, extensively apply to fields such as communication, Fibre Optical Sensor, industry control wire jumper, plastic optical fiber is also become one of the primary study object in this field with the joints of optical fibre that other optical fiber (as silica fibre) dock.

In order to reduce the loss of signal between the different fiber, need reduce plastic optical fiber as far as possible and rock with the relative of junction of other optical fiber, 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 provides a kind of connector that connects plastic optical fiber and other optical fiber of stablizing.

In order to achieve the above object, the technical solution adopted in the utility model is as follows:

A kind of plastic optical fibre connector, comprise ferrule assembly, adapter sleeve, fixture and swivel nut, described adapter sleeve comprises head and afterbody, the described head outside is provided with some blocked blocks, described fixture is provided with the hollow bulb that passes for adapter sleeve, and described hollow bulb inboard is provided with some draw-in grooves corresponding with blocked block.

In prioritization scheme of the present utility model, the draw-in groove of described fixture is step-like.

Alternatively, the number of described draw-in groove is 2～4.

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 holds by the blocked block on the adapter sleeve and the draw-in groove on the fixture, again by the afterbody of adapter sleeve and being connected of swivel nut, fixture can be subjected to displacement by relative adapter sleeve with vertical direction in level, and then can subtract the loss of signal of plastic optical fiber and other optical fiber junctions to a certain extent.

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 head 21 and afterbody 23.Head 21 is roughly rounded, and several blocked blocks 22 are arranged in its outer, in the present embodiment is 4, also can be set to other numbers according to actual conditions, as 2～6; Afterbody 23 is annular, and there is external thread in afterbody 23 outsides.

As shown in Figure 5, described fixture 3 roughly is square, the centre is provided with the hollow bulb 32 that passes for adapter sleeve 2, hollow bulb 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 is step-like, that is to say, the height of draw-in groove 31 is less than the thickness of fixture 3.

As shown in Figure 6, described swivel nut 4 is annular, is used for connecting other optical fiber (as silica fibre), 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.
