The invention relates to devices for fiber-optic communication and can be used as an outlet of fiber-optic connectors.
Known fiber-optic receptacle SC-type, intended for permanent connection of fiber-optical cables containing made of a plastic housing with fastened in it sleeve installed it centralizer, made in the form of floating split ceramic sleeve [1].
Also known fiber-optic receptacle ST-type containing metal case with centralizer, made in the form of floating split bronze Bush [2]. The disadvantages of these fiber-optical outlets are insufficient shock and vibration resistance, due to design features of their implementation.
The closest to the technical nature of the present invention is taken us as a prototype, fiber-optic receptacle FC-type, intended for permanent connection of fiber-optical cables containing metal body, inside of which coaxially fixed reducing sleeve installed it centralizer, made in the form of floating split ceramic sleeve [3].
The fiber-optic receptacle has a high accuracy of a joint in her convectors, but does not provide shock and vibration resistance at joining the single-mode optical fibers, due to the design features of the execution of its floating split ceramic sleeve.
Therefore, the use of the fiber-optic receptacle mobile objects, for example, in the lines of fiber optic transmission, installed on the rocket and space technology, leads to a disruption of airborne fiber-optic lines caused by mutual resonance oscillations tips ()arising from existing gap between housing socket and installed ceramic centralizer, which limits the field of application of this fiber-optic socket.
The aim of the invention is to increase the shock and vibration resistance of the fiber-optic socket while maintaining accuracy joint connectors and simplistic design.
This goal is achieved by the fact that in the fiber optic socket containing the body with centralizer, centralizer is in the form of floating coupling with the Central part of the external cylindrical surface of an annular groove, and the opposite ends of the floating coupling performed with external conical surfaces, building of the fiber-optic socket contains an internal annular groove, which is inserted additionally entered the locking located in the ring groove floating coupling.
The floating coupling can contain one or several elements, made in the form of the sectors with the outer ring groove, with the locking floating coupling can be made in the form of elastic split ring, either in the form of ring spring, floating coupling can be made in the form of elastic collet element having in the Central part of the external cylindrical surface of an annular groove, the opposite faces of the elastic collet element performed with external conical surfaces, and elastic collet element can contain in the Central part of the outer cylindrical the surface of the ledge for its fixing ring groove in the housing fiber-optic socket.
Increased shock and vibration resistance of the fiber-optic socket while maintaining accuracy joint connectors ensures the replacement of the centralizer, made in the form of floating split ceramic sleeve fiber-optic socket prototype centralizer as a floating coupling opposite ends of which are made with external conical surfaces, and elastic collet element can contain in the Central part of the external cylindrical surface of the ledge for its fixing ring groove in the housing fiber-optic socket.
Increased shock and vibration resistance of the fiber-optic socket while maintaining accuracy joint convectors ensures the replacement of the centralizer, made in the form of floating split ceramic sleeve fiber-optic socket prototype centralizer as a floating coupling opposite ends of which are made with external conical surfaces, allowing the center ferule convector due to a compressive radial force floating coupling.
Also, the advantage of the suggested fiber-optic socket is the simple design, small number of parts incorporated into the design of the wall outlet and therefore fast and easy Assembly of the fiber-optical socket.
