The invention relates to fiber optics and optonica. Can be used to connect groups of fiber-optic cables between themselves requiring at operation easy disconnection or connection of the end faces of the optical fibers.

Fiber optic connectors and connectors used in optonica for connecting optical fibers to each other. The purpose of the optical connector or connector - precise alignment and fixation of cores connected optical fibers for transmitting the optical signal from one fiber to another with minimal loss. As a rule, in modern connectors use the following principle alignment: link the fibers are fixed in precision tips (ferrule)that are inserted in the precision sleeve-centralizer. Centralizers are installed in the socket, each side of which is connected to the fork containing the tips of the connected fibers. For small values of the reflected signal, it is necessary to ensure that no air gap between the joined hearts fibers. It is provided with spherical ends. The connectors have a spring loading mechanism of the handpiece to provide normalized compression force of combined terminals (for most designs tips this force is 10 N), which guarantees the absence of air is Azora. Mainly fixing the connector in the plug is carried out according to the principles of push-pull (SC)bayonet fixing (ST) or using nuts (FC). Currently, most connectors are designed for connecting two optical fibers.

Known technology connection trunk (containing two or more fiber-optic fiber) fiber-optic cables that use MTMTP connectors, through which the connection 4, 8 or 12 optical fibers (fibres), and patch panels patch panels or cross-panels), are equipped with a fan Assembly connecting cables (fanout unit with the second connector. Laying and connection of cables with MT or MTP connectors, installed at the factory, do not require the use of special tools, since there is no need to make a cable termination. The MT connector is a combination of strips containing 4, 8 or 12 optical fibers. To connect with MT connectors between a used 2 installation guide pin and a spring clamp. Connecting cables, which are fan-shaped Assembly, is a short length of optical fiber, one end of which is installed in the MT connector, and the other conventional connectors (ST, SC, FC). Fan Assembly connecting cables mounted in universal patch panel. MT is connector cable attached to the MT connector Assembly, as usual connectors are connected to their respective adapters, patch panels. Thus it is possible to connect up to 24 fibers in a single patch panel (this uses two sets of MT connectors). For the implementation of the described technologies are needed, two patch panels, equipped with a fan-shaped assemblies connecting cables, and a cable of desired length with the established manufacturer MT (m) connectors on the ends. The disadvantages of this technology include the need for intermediate switching equipment (fan Assembly, patch panels), and, as a consequence, increased losses in the line, a limited number of fibers in the connector.

Known multi-channel fiber optic connector FOHC ITT Cannon (www.ittcannon.com), selected as a prototype. It consists of a plug and socket. The plug contains a matrix of fiber-optic trunk cable lugs. Each tip has a spring loading mechanism, which when connecting the connector provides the necessary clamping force. The socket contains a matrix is fixed in the casing centralizers with installed cable tips of the optical Assembly (similar to the fan Assembly used in MT technology). Fixing connectors connection by using nuts. In FOHC connectors the method of connection/disconnection of the connectors easier to judge what watali, than MTMTP connectors, and has a great resource. However, the installation of centralizers in the socket and terminals in the plug requires great accuracy in the manufacture of the connector, so the cable connected to the connector for factory use only. For these connectors required fan Assembly (as for MT technology), which increases insertion loss when using this connection.

The technical result of the invention is to facilitate connection and disconnection of the connector, the small size of the connector when connecting a large number of fibers, improving the accuracy of alignment and the creation of the necessary pressing force of the end faces of the fibers on each pair of connected optical fibers, the possibility of mounting optical fibers in optical fiber forks in the field, which allows you to refuse the application in fiber-optic networks patch panels.

The technical result is achieved by the fact that the centralizers of sockets made of elastic material. Part of the centralizer from the ends of the hollow cylinder to the junction of the tips of the forks are able to increase the size of the cavity so that the inserted fiber optic handpiece plug can freely pass in providing him or her part of the centralizer. One of the edges of the slot of each clamp is fixed in the material outlet. And on the other side with the AC on the water side of the insertion tip has protrusions, able to move so that the size of the cavity under the tip of the fork increases or decreases. On each side of the fiber optic socket has a slider in the form of a frame with bars along centralizers plates are able to move in the transverse axes of the cylinders of centralizers direction. In the plates, floaters, there are slots for the tabs on the free edges of the centralizers, or allowing the slider to move the tabs on the edges of the centralizers or the tabs to move the slider. There are tabs open position of the outlet, able to hold the sliders in the position in which the size of the cavities parts cylinder centralizers allow free flowing of the tips of the forks. In the center of each side of the outlet, where are the ends of the centralizers, are the shutter button tabs open position of the outlet, is able to release the latch by pressing on them by the plug when you place it into the socket. On the outlet, there are levers to move the sliders in the position that provides free removing each plug from the outlet. Each fiber optic plug has a movable grate is able to compress the elastic material or spring device podpruzhineny each tip. There is a lever to move the grating in the direction of compression of the elastic material or device podpruzhineny under de the action of the lever movement of the RAM sockets. There is a locking device of the lattice, capable of holding the bars in position, the compressed state of the elastic material or devices podpruzhineny tips and capable under the influence of the RAM sockets to release the bars to move into position, allowing the elastic material or device podpruzhineny to create a clamping force on each tip.

On Fig - spatial view of a fragment of a socket with clamp inserted in both sides of the tips of connected optical fibers.

Fiber optic connector works as follows. Plug 1 (Fig 1) is ready to connect to the socket 2 and the plug 3 is connected to the outlet 2. In the body 4 of the plug 1 is an elastic material 5. The elastic material has a hole for passing the optical fiber 6 with 7 tips. The elastic material has a form that allows you to press each handpiece the handpiece holder 8 with standardized effort (˜10 N) so that adjacent lugs had no effect on the clamping force of each other. On the elastic material includes protrusions 9, through which the movable grating 10 compresses the elastic part of the material around each fiber-optic cable. The grid holds the elastic material in a compressed state by means of the protrusion 11 on the lever to move the grating 12, which is retained by the locking device of the grating 13. The handpiece holder 8 (figure 3) is designed as a sleeve with a slot 14 for the passage of fiber-optic cable. On one side of the sleeve is fixed to the tip 7, the other end of the spring-loaded elastic material 5. The outside of the sleeve has a space 15 through which the sleeve is pressed against the inner side of the frontal plane of the body 16. The speakers and the front plane side of the lugs are located in the cavity of the protective casing 17 (Fig 1).

In the socket 2 from the side of the plug 1 (Fig 1, 3, 5, 7) ledge 18 on one end 19 of each of the centralizers 20, being in the groove 21 (5, 7) of the plate 22 of the slide 23, is retained by the slide and prevents the tab end 18 by the elastic force of the material of the centralizers to converge with the other end of the centralizer 24 fixed in the fixed part of the socket 2. As a result, the size of the cavities parts cylinder centralizers 25 is increased and allow free flowing of the tips of the fork. The RAM 23 (Fig 1, 5, 7) is retained by the latch open position 26 (Fig 1) from movement under the force of elasticity of the centralizers 20, transmitted through the protrusions 18 (5,7).

When placing the plug 1 and socket 2 (2, 4, 6, Fig) each of the nozzles 7 is in the centralizer 20, freely passing in the enlarged cavity of the centralizer 25 (3,7). The protrusions 27 of the RAM 23 (6) are held in shaped cutouts 28(figure 2) in a protective cover 17 of the plug 1. With full immersion of the lugs 7 in meant for hollow region of centralizers 26 to compress the ends of the lugs of the fork 1 (figure 4) to the ends of the lugs of the fork 3 with a force of compression of the parts of the elastic material between the holders of the lugs 8 (figure 2) and the projections 9 (parts, not compressed using mobile grid) fork (1) frontal plane 16 presses the button 29 of the latch open position of the outlet 26, the salt is bogda the slide 23 to move. The movable ends of the centralizers 19 (6,Fig) with the tabs 18 closer to the ends of the centralizers 24 fixed in the fixed portion of the receptacle, which reduces the size of the cavities parts cylinder centralizers 25 to a size that allows tightly cover the lugs 7 of the plug 1 (figure 2). When this shift plate 22 of the slide 23 between the rows of centralizers 20 (6), and the protrusions of the slide 27, moving in curved cutouts protective casing 28 (Fig 1), shift levers fixation device of the grating 13. The movable grating 10 (figure 2) together with the lever to move the grating 12 are shifted towards the inner part of the frontal plane under the force of compression of the elastic material 5. Elastic material, freed from the influence of the moving lattice, creates the necessary effort (˜10 N) compression ends of the lugs 7.

The correct connection of the plug with the socket is determined by the click of the latch open position of the outlet 26 and visually by changing the position of the lever to move the grating 12. All tips are firmly covered by centralizers, as the fixation device of the grating 13 can be opened only when the end position of the slide 23, when all cavities centralizers will be reduced to the size of the tips. It provides accurate alignment and fixation of cores connected optical fibers, as paginatecount effort (˜ 10 H) is performed after the tip will take coaxially with a counter tip position and does not introduce error into the process of alignment. The result can be reduced requirements for precision mounting of the tips of the forks, which allows you to connect the plug of the optical fiber in the field. Socket 2 holds the plug 1 by the projections 27 for shaped cutouts protective casing 28. Plate 22 of the slide 23 are held by the projections of the centralizers 18 in a position that does not interfere with the centralizers securely fix the alignment of the core of the connected optical fibers. The latch open position of the outlet 26 with the button 29 is held by the slider 23 in flush condition.

To extract the plug 1 from the outlet 2 (2) press the lever movement of the slide 30 in the direction of the connector. When turning the lever 30 to its ledge 31 actuates the lever to move the grating 12, under which the grating 13 compresses the elastic material 5, the locking device fixing the grating 13. Further rotation of the lever 30 causes movement of the slide 23 together with the protrusions 18 of the free ends 19 of the centralizers 20, releasing the lugs 7 of the plug 1. After the lever is released, the slider 23 under the force of elasticity of the centralizers 20 returns to the position in which to hold the latch open position of the outlet 26 (IG). When the protrusions of the slide 27 will move in curved cut protective cover 28 in position, allows you to easily remove the plug 1 from the socket 2, and the button 29 will rise over the fiber optic receptacle. Fiber optic connector shown in an initial open position (Fig 1, 3, 5, 7).

Thus, the proposed fiber optic connector is simple in operation, as one movement, no effort is made connection with the adjustment and fixation of all pairs of cores of connected optical fibers. After the tip of the plug 1 will take coaxially with opposing lugs of the fork 3 position, automatically elastic material 5 is clamp the ends of the optical fibers of the normalized force (˜10 N). The result is not entered, an error in the process of alignment, and can be reduced requirements for precision mounting of the tips of the forks, which allows you to connect the plug of the optical fiber in the field. One push on the lever 30 is the release of fiber optic handpiece that allows you to easily remove the plug from the socket.
