The present invention relates to fiber optic connectors, intended for the education of mechanical splices of optical fibers.

There is a wide variety of designs of fiber-optic connectors for education mechanical splices (splices in which the fibers are spliced together by mechanical means). An example of one type of mechanical connector bonding is described in U.S. patent No. 4946249. Each of the connectors described in this patent comprises a pair of semi-bodies, which, when assembled together, provide housing having a channel passing between them to accommodate the bonded fibers. Fiber, in General, have a coating that must be removed from the end sections of the fibers that join with each other to form a splice. The channel in the housing of the connector is wider at the ends of the housing for placement of coated sections of the fibers and in the middle of the box for naked fibers. Because there is more than one type of coating thickness fiber, some housing connectors have different channel diameters at opposite ends of the housing so that could be spliced together fiber of different sizes. There is also a corresponding housing of the connector, designed for splicing together optical fiber of each size. Sledovatel is but you want a range of different buildings connector.

In U.S. patent No. 5963699 described fiber-optic connectors for mechanical splicing of optical fibers containing the base and the cover, between which is clamped the bonded fiber by means of an external spring clip that holds the base and the cover together. The cover is formed of three separate sections, that is one of the middle section to clamp both naked parts of the bonded fibers and two end sections to clamp each of the two coated portions of the fibers. The spring clip is divided into three sections corresponding to these three sections cover so that the clamping force can be adjusted for each partition covers, independently from each other.

The present invention provides a receiving fiber optic connectors, which have major advantages over the known systems of the connectors described above, including:

(1) "promotionbest", i.e. the possibility of mounting the first optical fiber (or the first set of optical fibers in the connector for mechanical splicing and later mounting of the second optical fiber (second set of fibers), designed for splicing with the first fiber (fibers);

(2) the possibility of closing "polymethylene" connector for mechanical splicing so as to protect the interior of the connector and mounted fiber (mounted fiber) as long until it is formed by bonding the second optical fiber (optical fibers);

(3) clamping the first fiber optics (optical fibers) against movement in the directions x, y or z, as well as against rotation even if the second optical fiber (fiber) spliced to the first optical fiber (optical fibers)that enables the orientation of the split angle of the end surface of one (or each) of the first fiber, fixed for subsequent merging with the second optical fiber;

(4) the possibility of one connector mechanical splice to accommodate different fiber diameters, such as coated fibers with a diameter of 250 μm, and the coated fibers with a diameter of 900 microns;

(5) the universality connector mechanical splicing or not to contain the means for precise alignment of spliced optical fibers (where the numerical aperture of the fibers is such that it does not require precise alignment), or contain any one of the many centering means to meet specific requirements.

Other advantages of the present invention will become apparent from further description.

The first aspect of the present invention accordingly provides a receiving optical fiber connector (1) for the formation of mechanical splicing the first and second bare optical fibers (9) with UD is certain coatings, contains the body of the connector is divided at least into two parts (3, 5) along at least part of their length, constructed and arranged so that the optical fiber can be clamped between the parts, which has at least two main clamping sections (23)having dimensions for direct clamping on the naked part of the first and second optical fibers, the connector housing includes at least one additional clamping section (25)having such dimensions to be clamped on the covered part of one of the optical fibers, and the main clamping sections arranged so that the first optical fiber could be squeezed by the first of the main clamping sections, regardless of the second optical fiber, enabling clamping of the first fiber against rotary and axial movement relative to the housing of the connector to remain essentially untouched by subsequent clamping or unclamping of the second fiber.

The expression "bare fiber with remote coatings", in General, means that the end parts of the fibers to be fusion, removed cover, or only that of the fibers (or at least on their end parts) essentially no coverage. Remote cover, in General, contain a primer coating and/or buffer coating.

As described above, first the second aspect of the present invention provides a connector mechanical splicing, which provides the possibility of mounting in the connector of the first fiber and the second fiber to be subsequent merging with the first optical fiber, leaving unaffected the first fiber. For example, you may need to be deployed to the main part of the fiber network and subscribers subsequently connected to the network, as and when required. One example of why it can be important to leave unaffected the first fiber at the splice with him the second fiber is an example in which the end surface of the first fiber can be separated at an angle to the perpendicular (to its longitudinal axis) to prevent or at least minimize unwanted back reflections along the fiber end surface (which can disturb the data transmission in the network). A great advantage of the present invention is that it can facilitate mechanical bonding of the first fiber to the second fiber while maintaining the rotary orientation of the beveled end surface of the first fiber connector mechanical splicing and eliminate the need to change the orientation with the introduction of the second fiber.

This first aspect of the present invention enables clamping of the first fiber so as to remain essentially unaffected by subsequent clamping yerasimos second fiber, since the main clamping sections (which have dimensions for direct clamping on both bare optical fibers) contain at least two sections located so that the first fiber could be squeezed first section independently from the second fiber. The connectors described in U.S. patent No. 5963699, do not have this advantage because the middle section covers these connectors contains only one section having a size to clamp both of the bare fibers. Therefore, for clamping or unclamping of the second fiber after clamping of the first fiber will be necessary unclamping the first fibers of the middle section of the cover of such a connector. Now, although the connectors described in U.S. patent No. 5963699, also include a separate end sections which are independently clamped covered part of the fibers (and who do not have dimensions for clamping directly on the naked fiber with remote coatings), the problem gunzip it first fiber has not been solved, because it is a fact that the fiber clamped using only its outer covering (not clamped directly on the Central naked fiber), in General, able to rotate around the axis. Thus, the connectors described in U.S. patent No. 5963699, in General, not able to prevent the rotary orientation of the first assembled fibers when added on the second fiber or removed from the connector.

As indicated above, in addition to the two or more main clamping sections made for direct clamping on the naked fiber of the first and second optical fibers to remote coatings, the body of the connector preferably includes at least one or at least two additional clamping section having dimensions, made and arranged to clamp the coated portions of the optical fibers, that is, parts of the fibers, which were not removed coating. Two or more clamping section arranged to clamp the bare fibers, it is certainly not equivalent to such additional clamping sections corresponding to the present invention or the prior art.

In a preferred embodiment of the present invention includes a connector housing that contains at least four clamping section for clamping the first and second optical fibers.

At least two clamping sections of the four sections of the present invention are the main clamping sections in accordance with the present invention, and at least one, and preferably at least two clamping sections are preferred additional clamping sections.

In particularly preferred embodiments, the implementation of the present invention connect the ü contains, at least five of the clamping sections.

The connector may include at least three main sections, made to clamp directly on the naked optical fiber. The first of the main clamping sections may be positioned to clamp only on the first fiber, the second of the main clamping sections may be positioned to clamp only on the second fiber, and the third of the main clamping sections may be positioned to clamp both the first and second fibers.

The assembled housing of the connector corresponding to all aspects of the present invention preferably forms at least one channel located to accommodate optical fibers. The main clamping sections and the channel of the housing of the connector is preferably used to clamp the naked fibers of the first and second optical fibers in the channel. Channel (each channel) preferably has a first area and a second area larger than the first area, at the end of each first region. More preferably, the channel has a third region of larger diameter than the second region, at each end of the second region away from the first region. At least the second and the third region of the channel preferably have a circular cross-section.

In preferred embodiments of implementing the present invention, the connector can be the t includes centering means for combining the first and second optical fibers to each other. Fiber is combined by means of the centering means, sufficient for the formation of splicing, which minimizes optical loss so that any existing losses were at acceptable levels. The preferred centering means is a channel body of the connector, preferably a channel, referenced in the previous section. The channel preferably has such a size that the naked part of the first and second optical fibers to remote coatings form a tight fit in the channel. The channel may contain a groove of the housing of the connector, such as V-shaped or U-shaped groove, and/or it can be a channel of essentially round cross section. In addition or alternatively, the truing tool may contain the truing element, in which the first and second optical fiber can be placed and covered. The centering element can include a center channel for receiving and aligning optical fibers. The centering element can, for example, contain a receiver (or similar device), such as a capillary tube, for Example, the tube may be formed from glass. In an alternative embodiment, the centering element can contain at least one plate, preferably a pair of plates, each of which has an aperture to accommodate sootvetstvuyuschego first or second fiber. One of the plates or both plates may include a lens (for example, the microlens) to facilitate the interaction of light between the fibers. Plates can be similar to or the same as option implementation illustrated in Fig are simultaneously pending patent applications in the UK No. 0309908, filed April 30, 2003.

As indicated above in the summary of the essence of U.S. patent 4946249, fiber optics come in a range of diameters depending on the amount of coating applied to the bare fiber. For example, two standard fiber sizes are the diameter of 250 μm and a diameter of 900 microns. The fiber diameter of 250 μm, in General, it is known as a fiber primer coating (due to its relatively thin outer coating), and the fiber diameter of 900 microns, in General, it is known as the fiber buffer coating (due to the relatively thick outer covering). Very Central fiber, in General, has a standard diameter, regardless of whether it is a fiber coated with a primer coating or fiber coated with the buffer coating. The standard diameter of the bare fiber is 125 μm. Because the fiber comes in more than one size, it would be desirable to have a connector mechanical splicing, which could accommodate every size of the ox is the Korean people's army in one such device. This would avoid the need to distribute different connectors to accommodate for splicing fibers of different sizes and fibers with a combination of various sizes, as, for example, in U.S. patent No. 4946249. The third aspect of the present invention has the advantage of providing such a connector.

The first area of the channel of the connector preferably has a size to accommodate bare fiber with remote coatings (e.g., bare fibers having a diameter of approximately 125 μm), and each second region preferably has a size to accommodate the optical fiber having a primer coating (for example, fibers with a primer coating having a diameter of approximately 250 microns). Every third area is approximately the size to accommodate the optical fiber with a buffer coating (e.g., fiber buffer coating, which has a diameter of about 900 μm). Thus, one such device connector can accommodate bare fiber, with a primer coating and/or the fiber buffer coating. The second and the third region of the channel preferably have dimensions for placement on a dense planting of coated optical fibers of different respective sizes. Therefore, through the second and third areas of the trunk soy is Intel, the corresponding present invention meets the demand for fiber-optic connector that can accommodate different fiber sizes (due to the fact that the fibers have different thickness coatings on the naked fiber) in one such device connector.

The connector preferably further comprises a clamping element for holding the optical fibers in the clamped state in the body of the connector. The elastic clamping element can preferably be located for retention on the outer housing of the connector. The clamping element can be positioned to hold the housing parts of the connector together so that the fiber was clamped between the housing parts of the connector.

In some embodiments, implementation of the present invention, the connector may be positioned to hold a variety of couplings or other fastening elements, each of which is for attachment (e.g., wrapped) on the corresponding optical fiber so that the clutch or other fastening element is fastened in the housing of the connector during bonding of the fibers. Such couplings or other fastening elements can contribute to the preservation of the desired rotary orientation and/or axial position of the corresponding fiber in the connector.

The connector corresponding to the present the invention, can be preferably linked to education mechanical splices many first and second optical fibers (for example, for the formation of many splices fibers). The body of the connector can therefore contain many channels available to accommodate the many first and second optical fibers.

Now will be described examples of preferred embodiments of the present invention with reference to the accompanying drawings, in which

Fig.9 is a schematic illustration illustrating the centering means of the connectors of the present invention.

Figure 1 illustrates the components of the preferred fiber optic connector corresponding to the present invention. The connector 1 includes a connector housing having two parts 3 and 5, which divide the body of the connector in half along the length of the housing of the connector. Two parts 3 and 5 can be called paleobiologii housing of the connector. The first part 3 will be called the main part 3 and part 5 will be called a cover 5. The main part 3 is illustrated in detail in figure 4 and the cover 5 is illustrated in detail in figure 5. As the main part 3 and the cover 5 has a longitudinal groove which, when the alignment of these parts together to close the connector housing to limit longitudinal channel passing through the body of the connector to accommodate the optical fibers 9 (see Fig.3-8), being bonded to the connector in use.

The groove 7 forming the channel contains flowing in the longitudinal direction of the first region 11, the second region 13 located at each end of the first region 11, and the third region 15 located on each to the nce second areas 13 (opposite ends, adjacent the first region 11). Each second region 13 has a diameter that is larger than the diameter of the first region 11, and each third region 15 has a diameter that is larger than the diameter adjacent a second region 13. As described in this earlier application, the first area 11 of the trench 7 has such a size that the channel could accommodate bare fiber with remote coatings in dense planting, provided by the clip when the cover 5 and the main part 3 of the housing of the connector tightly pressed together (to each other). The naked optical fiber preferably has an outer diameter of approximately 125 microns.

As shown in figure 4, one of the parts of the body of the connector, preferably the main part 3, includes a groove having a semicircular cross-section, as part of the first area 11 of the channel. Another part of the body of the connector, preferably the cover 5, as shown in figure 5, is preferably essentially flat in the first area, in addition to small recesses 17, which contribute to the direction and to hold the fibers in place. The fact that the first area of the channel is not round in cross-section, but includes a flat section, contributes to the tight clamping of the naked fiber in the first area. However, the second and the third region preferably are essentially round in cross-section, campocatino figure 4 and figure 5.

As second and third, and second or third region may include one or more retaining elements for cutting into the corresponding fiber coating to ensure counteract axial traction, especially to counteract creep, which may otherwise take place over time. Figure 1 and figure 4 shows the retaining elements 19 in the third regions 15 of the trough 7 of the main part 3.

As shown in figure 1 and figure 2, the connector may include a stub 21 intended for closing and preferably for sealing the ends of the troughs 7 before installation and during the installation of optical fibers for splicing. The stub 21 is preferably prevent the penetration of external dust or other dirt in the connector, and preferably to access water in the connector, which may have an adverse effect on the integrity of the splice. The plugs are removable from the channel to allow insertion of optical fibers.

As shown in figure 1 and figure 5, at least one of the housing parts of the connector, preferably the cover 5, is divided into many sections 23 and 25. Sections 23 and 25 are clamping sections of the body of the connector. As illustrated, there are five clamping sections, containing three main clamping sections 23, arranged to direct the second clip on the naked optical fiber in the first area 11 of the chute 7, and two additional clamping section 25, arranged to clamp directly on the covered parts of the optical fibers, second and third regions of the trench 7.

Figure 5 illustrates how the clamping sections 23 and 25 are separated from each other along the length of the housing of the connector. There is a continuous strip 27 of the connector housing, passing, in General, along one edge of the cover 5, and each clamping section passes of the strip 27. In addition to communication through the strip 27, each clamp section is separated from each adjacent clamping section through the gap, providing in accordance with this, the possibility of movement of the clamping sections and in accordance with this clamp independently of each other.

As more clearly shown in figures 1 and 6, the connector also includes an elastic clamping element 29 made in the form of an elastic metal element having, in General, a U-shaped cross-sectional configuration, which is designed to hold the outer housing of the connector. The elastic clamping element 29 is located to hold the cover 5 and the main body 3 together so that they are tightly crimped around the spliced optical fibers. Two, in General, parallel arm elastic clamping element is divided into clamping section 31, which form part of the respective clamping sections 23 and 25 of the connector housing. Clamping section 31 of the elastic clamp the second element provides the possibility of clamping sections 23 and 25 of the connector to hold the fibers independently from each other. In the longitudinal direction of the Central clamping section of the elastic clamping element 29 includes an aperture 33 located to accommodate the protrusion 35 on the housing of the connector for holding the clamping element in place on the body of the connector.

Because the body of the connector and the elastic clamping element includes three separate main clamping sections arranged to overlap with the first region 11 of the chute 7, the naked part with a remote coverage of two optical fibers, bonded to the connector can be clamped independently of each other. In particular, the first main clamping section clamps 23a only the first bare optical fiber, while the second primary clamp section 23C clamps only the second bare optical fiber and the third main clamping section 23b clamps the first and second bare optical fiber. Therefore, a great advantage of the present invention (as described previously) is that the first optical fiber can be mounted in the housing of the connector in preparation for splicing with the second optical fiber mounted in the housing of the connector later. The end surface of the first optical fiber preferably dissected under indirect angle relative to the longitudinal axis of the fiber to minimize reflections in the opposite direction. As a way to ease Crixivan what I first fiber to the second fiber (also have not perpendicular end surface) it is preferable to define and maintain the orientation of the end surface of the first fiber in the body of the connector. It is a fact that the second fiber may be inserted into the body of the connector and spliced with the first fiber, without requiring you to keep the orientation of the first fiber nezajimala the first main clamping sections 23a of the first fiber means.

The connector described in U.S. patent No. 5963699, does not have the above advantages, since the bare fiber section of both fibers are clamped one and only one clamping section of the connector. The fact that there are separate clamping sections, which are separately clamped covered part of the fibers, is not conducive to the preservation of orientation of the fibers, since the clamp to the floor (and not to the naked fiber), in General, does not fix the orientation of the fibers against rotation.

Figure 7 shows the schematic diagram of the assembled connector, illustrating how the cover 5 and the main part 3 can be slightly separated to facilitate insertion of the optical fibers to be fusion. Cover 5 and the main part 3 together provide a recess 35 on the open side of the elastic clamping element 29. The recess 35 has an inclined side walls 36. With the introduction of special provisions wedge element 37 in the recess 35, the inclined side walls 38 of the wedge element 37 cooperate with the side walls 36 of the recess to urge the divergence of the cover and the main part will be seeing what Ino certain amount. This facilitates axial introduction of fiber optics (optical fibers) in the channel formed by the groove 7. Wedge element 37 is arranged to open the cover and the main body selectively in a separate clamping sections of the connector, as described above.

On Fig illustrates a variant of the fiber optic connector shown in Fig.1-7. In this embodiment of the present invention, the second area 13 of the chute 7 are located to receive the couplings 39 (or other fasteners), pressed (or otherwise attached) to the respective optical fibers 9. Clutch 39 preferably include protrusions on their outer parts, which are fitted in the connector housing in areas 13 to fix the clutch and, therefore, their corresponding optical fiber in a special rotary orientation. The clutch 39 is preferably also axially retain their respective fibers in the connector to ensure counteract axial traction and/or axial pushing of the fibers relative to the housing of the connector.

The cover and the main body connector (all embodiments of the present invention) is preferably formed from a polymeric material, such as sulfide Polyphenylene (PPS). The elastic clamping element may be formed from a polymer or metal, but metal in General, which is preferable. Preferred metals include stainless steel and beryllium-copper alloy (beryllium bronze). The coupling is preferably formed of metal, and the plugs are preferably formed of a polymeric material.

Figure 9 shows a schematic illustration of three embodiments of the centering means of the connectors of the present invention. Figure 9(a) of the centering means is a channel of the housing of the connector, and in the longitudinal direction of the Central main clamp housing section connector (called "Clamp 2") provides the clamp directly on both of the bonded naked optical fibers, combining two fibers to each other. The other two main clamping sections (called "Clamp 1 and Clamp 3") on each side of the Clamp 2 clamp only on their respective individual fibers, allowing independent clamping of the fibers. In addition, in each of these embodiments has a centering element located between the two main clamping sections located to align two fibers to each other. Figure 9(b) of the centering element is a tube, in particular a glass capillary tube. Figure 9(C) centering element comprises a pair of plates, each of which has an aperture for the fiber and lean is at ("lens"), located to facilitate effective interaction of light between the fibers. As indicated earlier in this description, the plate can be the same or similar variant implementation, illustrated in Fig are simultaneously pending patent applications in the UK No. 0309908, filed April 30, 2003.

FIELD: physics, optics.

SUBSTANCE: invention concerns fibre optics and optronics. It can be applied to linking of groups of fiber-optical cables among themselves. In the socket the centralisers are executed from an elastic material. One of edges of a gash of every centraliser is fixed in a socket material. On other edge from each leg of a tip there are salients. From each leg of the fiber-optical socket the slider is available. There are holdfasts of an open standing of the socket. At centre of each of the socket legs, there are the buttons relieving a holdfast. Each fiber-optical plug has the mobile lattice of squeezing of springs or an elastic material for plug tips springing. In each plug there is a lever. There is a device of fixing of a lattice. Vacuities of the centralisers densely sweep plug tips. Thus moves a slider, fixing a plug in the socket and voiding the mobile lattice for travel. The elastic material creates necessary effort of squeezing of end faces of tips.

EFFECT: simplification of linking and socket release, the small sizes of a socket at linking of major number of fibrils, pinch of accuracy of alignment and making of necessary clamping effort of end faces of fibrils on each pair of joined light guides, possibility of installation of optical fibrils in fiber-optical plugs in field requirements that allows to refuse application in fiber-optical networks of patch-panels.
