Description

Joints of optical fibre loose mail

Technical field

The utility model relates to a kind of fibre-optical splice loose mail, relates in particular to a kind of joints of optical fibre loose mail.

Background technology

The joints of optical fibre, optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it gets up the accurate docking of two end faces of optical fiber, so that being coupled to receive in optical fiber to greatest extent, the luminous energy of launching fiber output goes, and make because it is got involved optical link and the impact that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have affected reliability and the properties of optical transmission system.

The joints of optical fibre can be divided into polytype by the difference of transmission medium; And the existing FC2.0 joints of optical fibre adopt thread locking structure, namely put at stay pipe and gland external thread and the internal thread that setting respectively can be worked in coordination, for guaranteeing the quality of product, in use do not become flexible in production run after locking, need to put screw thread glue on accessory, lock screw again, too loaded down with trivial details in process of production, production efficiency is low.

Summary of the invention

Technical problem to be solved in the utility model is, the joints of optical fibre loose mail that provides that a kind of structure is firm, can not become flexible in use procedure.

in order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of joints of optical fibre loose mail, by tail pipe, clamp, stay pipe, spring, shell, fixedly headgear and dust cap form, described tail pipe is socketed in the clamp head, the clamp afterbody is socketed in the front end of stay pipe, the stay pipe end and fixedly headgear be connected, described spring is arranged in clamp, casing is connected on stay pipe and fixedly outside headgear, dust cap is embedded in fixedly headgear afterbody, described stay pipe end is provided with positioning guide rail and stuck point, fixedly the headgear front end is provided with locating channel and the bayonet socket that can coordinate with described positioning guide rail and stuck point respectively.

Compared with prior art, usefulness of the present utility model is: this FC2.0 fibre-optic connector structure is simple, and production efficiency is high, and is easy to operate, does not need to use screw thread glue, and the environmental protection structure is firm.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is the utility model joints of optical fibre loose mail structure explosive view.

In figure: 1, tail pipe; 2, clamp; 3, stay pipe; 31, positioning guide rail; 32, stuck point; 4, spring; 5, shell; 6, fixing headgear; 62, bayonet socket; 61, locating channel; 7, dust cap.

Embodiment

Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:

A kind of joints of optical fibre loose mail shown in Figure 1 is by tail pipe 1, clamp 2, stay pipe 3, spring 4, shell 5, fixedly headgear 6 and dust cap 7 form; Described stay pipe 3 ends are provided with positioning guide rail 31 and stuck point 32, and fixedly headgear 6 front ends are provided with locating channel 61 and the bayonet socket 62 that can coordinate with described positioning guide rail 31 and stuck point 32 respectively;

During installation, at first clamp 2 afterbodys are socketed in the front end of stay pipe 3, then stay pipe 3 ends are coordinated with fixing headgear 6, wherein the guide rail 31 on stay pipe 3 embeds with locating channel 61 on fixing headgear 6 and coordinates, stuck point 32 on stay pipe 3 coordinates with bayonet socket 62 on fixing headgear 6, and wherein said spring 4 is arranged in clamp 2 in advance, then shell 5 is socketed in stay pipe 3 and fixedly outside headgear 6, at last tail pipe 1 is socketed in clamp 2 heads, dust cap 7 is embedded in fixedly headgear 6 afterbodys.

This joints of optical fibre loose mail is simple in structure, and production efficiency is high, and is easy to operate, does not need to use screw thread glue, and the environmental protection structure is firm.

It is emphasized that: above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
