Abstract

The utility model relates to an optical fiber connector which comprises an external body, an internal body, a ceramic insert core, a metal handle, a connecting part, a positioning pin, a flex and a protective tail sleeve, wherein the external body is sheathed on the inner side of the internal body, the metal handle and the ceramic insert core are penetrated in a central through hole of the internal body, the front end of the metal handle is connected with the back end of the ceramic insert core, the tail end of the internal body is sheathed on the connecting part, the back end of the connecting part is embedded in the positioning pin, the protective tail sleeve is sheathed on the connecting part and the flex, a sheath of the flex tightly wraps an optical fiber, and a projecting lug and a through slot are respectively arranged on two sides of the outer wall of the internal body. The optical fiber connector has the benefits that the flex optical fiber can be fixed by embedding the back end of the connecting part in the positioning pin, thereby solving the problem of complex production process and being applicable to assembly requirements of a novel FTTX optical fiber connector; as the internal body, the connecting part and the flex constitute a whole, when the ceramic insert core receives axial action force, a spring shrinks, the internal body, the connecting part and the flex retreat accordingly, thereby effectively avoiding bending and fracturing the optical fiber.

Description

A kind of joints of optical fibre

Technical field

The utility model relates to technical field of optical fiber communication, relates in particular to a kind of joints of optical fibre.

Background technology

The joints of optical fibre generally are meant and carry out the device that detachable (activity) is connected between optical fiber and the optical fiber, it gets up the accurate butt joint of two end faces of optical fiber, so that being coupled to receive in the optical fiber to greatest extent, the luminous energy of launching fiber output goes, and make because it is got involved optical link and the influence that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.The existing joints of optical fibre of Ying Yonging have influenced reliability and every performance of optical transmission system to a certain extent; It is too complicated mainly to show as its structure, can cause complex manufacturing, lacks corresponding connector loose mail for novel optical fiber in addition, because parts connect the bending of optical fiber and the situation that fractures of easily causing.

The utility model content

At above defective, the utility model provides a kind of joints of optical fibre that structure, production technology are simple, can effectively avoid fibre-optical bending and fracture of having simplified, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of joints of optical fibre, comprise outer body, interior body, ceramic insertion core, metal handle, web member, register pin, rubber-insulated wire and protect the tail cover, the body outside in outer body is socketed on, being installed with metal handle in the central through hole of body in being somebody's turn to do is connected with the ceramic insertion core rear end with the front end of ceramic insertion core and metal handle, interior body tail end is socketed on the web member, described web member rear end embeds register pin, described tail sheath is placed on web member and the rubber-insulated wire, the crust tightly packaged fiber of this rubber-insulated wire, described interior body outer wall both sides are respectively equipped with lug and groove; The front end of described metal handle is provided with ring-shaped step, spring housing be located on the metal handle and be arranged at ring-shaped step and the web member front end face between.

The beneficial effect of the joints of optical fibre described in the utility model is: the rear end embedding register pin by web member can be fixed rubber-insulated wire optical fiber, has solved the problem of complex manufacturing, can adapt to the connector assembling requirement of novel FTTX optical fiber; Because interior body, web member and rubber-insulated wire can constitute an integral body, when ceramic insertion core was subjected to axial force, spring shrank, and interior basis, web member and rubber-insulated wire are drawn back thereupon, can effectively avoid the bending of optical fiber and fractureed.
