The technical field

The present invention relates to a connector for optical fibers.

The level of technology

In optical fibers, the optical signal can be transmitted through the fibre, delivering relatively large amounts of information compared to conventional copper wire. However, the information signal is subject to distortion or loss level when an unstable connection between the ends of the optical fibers. Therefore, compounds that provide good signal, proposed several different technical solutions.

One solution is that the ends of the optical fibers fuse with each other. This method ensures the constant presence of the ends of the fibers adjacent to each other, but with fusion involve some problems. Optical fibers are often lagerbuchse secondary materials, enhance some desired properties. The actual fusion usually leads to a violation of doping on the ends of the optical fibers. In addition, the fusion can usually only be used with pairs of fibers that are doped with the same secondary material.

Other solutions include the use of the handpiece, in which there are two ends of the optical fibers. The tip has a larger size, and therefore the optical fiber can easily enter it. In the lug m is tenderly to place glue for the best retention of optical fibers together. The difficulty with this solution is that the ends of the optical fibers are not simple interface with each other because of the enlarged size of the hole in the tip, and therefore the signal quality may be affected. The tip can be mechanically reduced in size, for example by compression, so that the optical fiber was fixed mechanically. But this method can easily damage the optical fiber, usually fragile.

That is, there is a need to provide an improved connector for connecting optical fibers, which is easy to use and provide a good signal between the optical fibers.

The invention

The first object of the invention relates to a connector for connecting optical fibers. The connector has a body. The housing has a first end and a second end, and a channel for fiber passing from the first end to the second end. The housing is divided into a multitude of fingers passing longitudinally at each end.

Description of the preferred option of carrying out the invention

Referring to figures 1, 2 and 3, which show the connector 10 according to the first variant implementation of the present invention. The connector 10 is used to connect ends of the first and second optical fibers 12 and 13 (see figure 3)to the optical fiber 12 and 13 were able to pass optical signals at the specified with the unity. The connector 10 has a housing 14, which may be essentially cylindrical. The housing 14 has a first end 16 and second end 18.

The channel 20 of the fiber passes from the first end 16 to second end 18. The channel 20 of the fiber used to hold the two ends of the optical fibers 12 and 13 fit end-to-end to each other, with the possibility of transmission of optical signals between them. The channel 20 of the fiber has such a size at which the connector 10 is making a small amount of compressive force on the ends of the optical fibers 12 and 13, to ensure retention of the fiber 12 and 13 in abutting end-to-end to each other when they are inserted in the connector 10. It should be noted that the compressive force applied to the optical fibers 12 and 13, should be appropriately small so as not to damage or not to break the fibers 12 and 13.

The housing 14 is divided into a set of first fingers 22, which pass from the first end 16 to second end 18. The first fingers 22 to hold the first optical fiber 12 in a predetermined position in the connector 10 with the introduction of optical fiber 12 to the connector 10. By providing the required length for the first fingers 22 compressive force of the connector 10, acting on the optical fiber 12 and 13, can be adjusted and you can change the length of the body 14 of the connector. The housing 14 of the connector can be divided into the oboe appropriate number of first fingers 22, for example, four of the first finger 22. Either the connector 10 may have more or fewer first fingers 22 three or five fingers. The first fingers 22 may take any suitable part of the circumference of the body 14. For example, the first fingers 22 can take about 90° circumference. The first fingers 22 can be formed by any appropriate method, such as milling of the slots 24 in the axial direction of the first end 16 as is clearly shown in figure 2.

Again referring to Figure 1: the housing 14 may have a variety of second fingers 26 extending from the second end 18 to the first end 16. The second set of fingers 26 to hold the second optical fiber 13 in a predetermined position in the connector 10, with the introduction of the second optical fiber 13 in the connector 10. The second set of fingers 26 can have the size, length and quantity similar to the first fingers 22. Or performance of second fingers 26 may be different from the first finger 22 - according to the mechanical properties of the second optical fiber 13. For example, the second set of fingers 26 may be shorter or longer than the first fingers 22. The second set of fingers 26 can be formed in the appropriate way, for example by milling arranged in the axial direction of the slots 28, included in the second end 18, which is more clearly presented in figure 2.

Again referring to Figure 1: first and second fingers 2 and 26 can be displaced relative to each other around the circumference - according to Figure 1. The offset angle may be any appropriate angle, for example 45°.

The fingers 22 and 26 can pass along the body 14 of the connector at a sufficient distance from their respective ends to overlap each other to some part of the body 14 of the connector. This overlap allows even more to adjust the compressive force applied by the housing 14 of the connector on the optical fiber 12 and 13, in particular the place where the first and second optical fibers 12 and 13 abut end-to-end to each other.

The connector 10 may be made of a material having the property of storing the original shape and return to it. In other words, from a material which, when deformation at rest any appropriate means shifting from returning to its rest state, when the deformation factor is no longer valid. An example of such a material is any material that is deformable at its limit of elasticity under the influence of mechanical deformation. Another example is material, appropriately expanding under the influence of increasing temperature and then returning to its original state of rest, when the temperature decreases to the initial temperature.

The connector 10 may be made of any of a number of a few the different materials, depending on the specific environment in which the connector is used, and the specific legal standards that must be observed in the manufacture and use of the connector 10. The connector 10, for example, can be made of a polymeric material, such as isostatic 1-polybutene, piezoelectric ceramics, alloys of copper, including two - and three-component alloys such as copper-aluminum, copper-zinc, copper-aluminum-beryllium alloys, copper-aluminum-zinc alloys, and copper-aluminum-Nickel alloys; Nickel alloys, as nickeltitanium-iron alloys and nickeltitanium-cobalt alloys, iron alloys such as iron-manganese alloys, iron-manganese-silicon alloys, iron-bromomalonate alloys and iron-chromogranine alloys; aluminum alloys and high elasticity of the composites, which can be metallic or polymeric reinforcement.

To connect two optical fibers 12 and 13 channel 20 for fiber increases due to deformation of the connector 10 in any suitable manner. For example, the connector 10 can be heated to a sufficient temperature for sufficient implementation of thermal expansion of the connector 10 to the optical fiber 12 and 13 can be inserted into the channel 20 to the fiber. The required volume Naga who evania and the desired final temperature of the connector 10 depend on the material, made of the connector 10.

In the channel 20 for fiber, you can enter the gel, having essentially the same refractive index as the optical fiber 12 and 13. The gel provides a uniform optical properties across the connection between the optical fibers 12 and 13, allowing reduced signal loss occurring as a result of internal reflection and refraction of the optical signals at the ends of the optical fibers 12 and 13.

The optical fibers 12 and 13 is normally covered by a cover 30, which among other things protects the optical fibers 12 and 13 from mechanical damage during installation and use. The combination of the shell 30 and the optical fibers 12 and 13 forms a cable 32 or 34, respectively. The shell 30 at the ends of the optical fibers 12 and 13 is removed, releasing the optical fiber 12 and 13.

The optical fibers 12 and 13 is inserted into the heated connector 10. When inserted, the optical fiber 12 and 13 displace excess gel that is located in the channel 20 to the fiber. Superseded gel may come out of the connector 10 through the slots 24 and 28.

After the optical fibers 12 and 13 will be fully inserted into the heated connector 10, their respective ends will abut end-to-end to each other. Then, the connector 10 can be cooled so that it has been returned to its original size. Upon return of the connector 10 in its u who ronically the size of the fingers 22 and 26 and the housing 14 will make essentially the specified compressive force on the optical fiber 12 and 13, to be sufficiently significant to hold the optical fibers 12 and 13 back to back to each other, but small enough so that the optical fibers 12 and 13 would not be damaged by compression.

During return of the connector 10 in its original state, the connector 10 may slightly pushing the ends of the optical fibers 12 and 13 from each other. That is, it may be necessary to hold the optical fibers 12 and 13 in a fixed position during the stage when the connector is returned to its original size, to prevent the optical fibers 12 and 13 to be displaced from each other. For example, the shell 30 covering each optical fiber 12 and 13 can be fixed clamp using a fixed set of clamps 36 according to Figure 3, resulting in axial movement of the optical fibers 12 and 13 will be removed. By holding the shell 30 reduces the risk of damage to the optical fibers 12 and 13.

Referring to Figure 4, showing the connector 40 according to the second implementation of the present invention. The connector 40 is similar to the connector 10 - with the exception that the connector 40 includes germosen part 42, which passes through a portion or the entire length of each finger 22, 26. Germusica portion 42 may extend from the free end of each finger 22, 26 as shown in Figure 4. Germusica part 42 Phi is for optical fibers 12 and 13 in abutting end-to-end to each other, when the connector 40 is returned to its original quiescent state from the deformed state.

For each of the first finger 22 germusica part 42 can be made by milling a variety of transverse slots 44 in each finger 22. The slots 44 may be made by milling in each finger 22 so that they pass across ceredano from each edge of the circumference of each finger 22. Addressing Figa, the slots 44, each of which may have a thickness T1, define a set of transverse germosen fingers 46, each of which has a thickness T2. The thickness T1 of the slots 44 and the thickness T2 germosen fingers, and also the material of the connector 40 can be selected to provide the required elasticity and deformability of the fingers 22 at a given mechanical load. The slots 44 define germosen fingers 46.

The slot 44 is more clearly shown in figure 5. Each slot 44 is made by milling only partially through the fingers 22, and therefore the portion 48 remains without drillings. The part 48 is connecting part, which connects adjacent germosen fingers 46. The connecting portion 48 may be of any appropriate form. For example, the connecting portion 48 may be essentially wedge-shaped and may be only partially radially inward of their respective finger 22. It was discovered that the wedge-shaped form of Celesio the different deformation and return to its original form germosen parts 42.

Germosen part 42 on the fingers 26 may be similar to those parts of the fingers 22. Germosen part 42 on the fingers 26 can be in the form of milled slots 44, which ceredano pass from each side of the circumference of each finger 26. The thickness T1 of the slots 44 and the thickness T2 of the transverse germosen fingers 46 on the fingers 26 may be the same as the thickness of the fingers 22, or the other depending on the mechanical properties of the optical fiber 13.

Addressing Fig.6b, showing one of the fingers 22, 26 in a deformed state. In a deformed state germusica part 42 is compressed. As shown in a deformed state generally parallel germosen fingers 46 are in contact with each other, and generally parallel side edges of the slots 44 form an angle of θ1. The thickness T1 of the slots 44 determines the maximum angle θ1 for germosen fingers 46. These parameters are based on the limit of elasticity of the material for the connector 40 and based on the requirements of a particular installation, for example in accordance with the environment in which the connector will be used.

In a deformed state germusica part 42 distorts the channel 20 of the fiber, and therefore, the channel 20 of the fiber is divided into many segments 50, each of which is located at an angle θ2 to the longitudinal axis of the connector 40. Because the segments 50 is aspolozhena unevenly with respect to each other in a deformed state, therefore, the optical fiber inserted in the channel 20 of the fiber is firmly clamped in it unevenly spaced segments 50. Configuration germosen part 42 can pick up to ensure an appropriate angle θ2 to the optical fiber 12 or 13 would be firmly clamped without damaging it. Clamping action germosen part 42 excludes a small deviation from each other of the optical fibers 12 and 13, when the connector is returned from the state of thermal expansion, for example, in its initial state of rest as shown in Figa. When clamping the optical fibers 12 or 13 germosen part when the connector 40 is in a deformed state, it becomes unnecessary compression of the shell 30 of the cable 32 or 34, which may be required when using the connector 10.

Referring to Fig.7, which shows the node 60 of connector used for connection of optical fibers 12 and 13 and which contains the connector 10 or the connector 40. The node connector 60 also includes a Central shell 62, the first and second end elements 64 and 66 and may contain the transmitter 68 signals and the receiver 70 of the signals.

The Central sheath 62 is more clearly shown in Fig. The Central sheath 62 may be essentially tubular and may have a hole 72 at each end, the size of which is configured to accommodate and retain h is STI one of the end elements 64 and 66 (see 7). Each hole 72 may end with the inner shoulder 74, which provides a bearing surface for the ends of one of the end elements 64 and 66. Each hole 72 can contain all the channel 76, which is aligned with the circular thickening 78 on each of the end elements 64 and 66.

The passage 80 between the shoulders 74 connects the two holes 72. The size of the passage 80 provides fixed in a desired position of one of the connectors 10 and 40, and therefore one of the ends 16 and 18 of the connector 10, 40 passes in each of the holes 72 (see Fig.7).

A pair of radial holes 82 may pass through the Central membrane 62 on the line, which is located on the longitudinal center of the Central shell 62. Radial holes 82 extending from the outer surface of the Central membrane 62 into the passage 80 at the opposite points of the circumference of the Central shell 62. The transmitter 68 signals and the receiver 70 of the signals can pass through the radial holes 82 (see Fig.7). Transmitter 68 signals may be, for example, an optical fiber which transmits the light beam. The receiver 70 of the signals may be any appropriate type of receiver, such as another optical fiber which has a capability of receiving signals from the transmitter 68. The receiver 70 may be accomplished by connection means to enhance or sootvetstvuyuschemu data (not shown) for determining the signal.

Referring to Fig.7, the connector 10, 40 can be installed in the passage 80, and therefore the longitudinal center of the connector 10, 40, designated as C, is aligned with the holes 82. In addition, the connector 10, 40 may be oriented so that the slots 24 or 28 are centered with radial holes 82 so that the receiver 70 is provided to receive signals from the transmitter 68 through the connector 10, 40. At least one pair of slots 24, 28 can be carried out from its respective end 16, 18 past the longitudinal center of the connector 10, 40, and therefore, the receiver 70 can "see" the transmitter 68. Alternatively, the connector 10, 40 may have a transverse passage, which passes transversely through the connector and on the longitudinal center of the connector 10, 40.

End elements 64 and 66 are installed in the holes 72 and leave them outside. In the end elements 64 and 66 are the ends of the cables 32 and 34, respectively.

End elements 64 or 66 is shown more clearly in Figure 9. End element 64 has on its outer end a hole 84 sums up the shell. The hole 84 accommodate the shell encompasses and captures the shell 30 of the cable 32. The hole 84 accommodate the shell has an internal shoulder 86, which may rest against the shell 30 during the connection process. The outer end of the hole 84 accommodate the shell can be extended to decrease the Oia voltage, acting on the optical fiber 12 at the bend of the cable 32 in the part that comes out of the end element 64.

Each end element 64 at their respective inner ends has a hole 88 accommodate the connector. The hole 88 accommodate the connector has a size that enables the receiving and fixing the connector 10, 40 and centering of the connector 10, 40 and an end element 64 relative to each other (see Fig.7).

The passage 90 is held between the radial center of accommodating the connector holes 88, allowing the optical fiber 12 to pass from the end of the shell 30 in the connector 10, 40.

End element 66 is similar to the end element 64 and encompasses and captures the end of the cable 34 in the same manner as end element 64 encompasses and captures the end of the cable 32.

For connection of the cables 32 and 34 and, in particular, the optical fibers 12 and 13 through node 60 of the connector perform the following steps. Node 60 of the connector can be assembled as a single unit by any appropriate means.

Before using the node 60 of the connector, a portion of the shell 42 around the optical fibers 12 and 13 is removed, exposing the selected length of each of the fibers 12 and 13. The ends of fibers 12 and 13 split any relevant splitting means, such as a laser, resulting in each ka is barely 12 and 13 is released the same length. Splitting also provides a substantially perpendicular end surfaces to the longitudinal axis of the optical fibers 12 and 13 in order to properly mate.

The node connector 60 can be heated, so that the connector 10, 40 expanded sufficiently and made it easy to insert the optical fibers 12 and 13. The transmitter 68 and receiver 70 are driven, and the light beam or other suitable signal, for example, is transmitted through the connector and received in the receiver 70. In the channel 20 to the fiber in the connector, you can enter the gel, and then with the introduction of optical fibers 12 and 13, the gel will fill any gaps in the junction between them to prevent the loss or distortion of the optical signal transmitted on the optical fibers. The gel has essentially the same refractive index as the optical fiber 12 and 13.

The ends of the cables 32 and 34 are then injected in the host shell holes 84 in the node 60 of the connector to the ends of the shell 30 has reached an internal shoulder 86. The passages 90 guide the ends of the optical fibers 12 and 13 in the channel 20 to the fiber in the connector 10, 40. The optical fibers 12 and 13 very slowly pushed into the channel 20 to the fiber, and thus verified the absence of violations of the light beam from the transmitter 68 and its reception by the receiver 70. Excess gel in the channel 20 to the fiber gradually replaced by the promotion of optical in the curl 12 and 13, and it can seep through the slits 24, 28, and possibly through the slots 44.

The promotion continues until the light beam is not disturbed, indicating that the optical fibers 12 and 13 are adjacent to each other end-to-end in the longitudinal center of the connector 10, 40. It should be noted that the slots 24, 28 or passage in the connector 10, 40 for the light beam may have a size large enough to accommodate some offset from the line of centers of the adjacent end-to-end to each other of the ends of the optical fibers 12 and 13.

After ensuring contiguity butt node connector 60 is cooled, so that the connector 10, 40 newly adopted its original size. If the connector 10 is used in the node 60, the shell 30 of the cables 32 and 34 of the clamp to ensure that the optical fibers 12 and 13 are not moving away from each other during the cooling node 60 of the connector.

If the connector 40 is used in the node 60, the clamp shell 30 is not required. The connector 40 can be slightly compress mechanical or other appropriate means, to germosen part 42 squeezed optical fiber 12 and 13, thus providing abutting end-to-end to each other of the ends of the optical fibers 12 and 13.

After cooling node 60 of the connector end elements 64 and 66 is fixed connected to the cables 32 and 34, respectively, for example, the jaws of the tool to compress the stub portion 92 is anavah elements 62 and 64 to the shell of the cables 32 and 34.

The connectors 10, 40 in accordance with the present invention can provide one or more of the following advantages when used for connection of optical fibers. For example, one additional advantage is that the connectors 10, 40 facilitate providing a tight alignment of two optical fibers, and the ends of the fibers are centered relative to each other and are centered in adjacent end-to-end relative to each other. One additional advantage is that the connectors 10, 40 according to the present invention support a compressive force pushing the optical fibers to each other. Due to this decrease the air gap between the ends of the fibers, which can occur when using other compounds known from the prior art. One additional advantage of the connectors 10, 40 is that they provide a clamping force on each end for durable retention of the fibers together. In particular, the connector 40 can provide a greater clamping force than the connector 10.

Referring to Figure 10, which shows the distribution of stresses in the connector 10 when the containment therein of a pair of optical fibers (not shown). Although the actual distribution of stresses in the connector 10 is not discrete, Figure 10 shows iskrenie areas with multiple voltages, to show the stress distribution in General. Areas with relatively low voltages shown position 94. Areas with relatively greater stresses shown position 96. Areas with the highest voltage is shown by position 98. In the drawing, Figure 10 shows that the voltage varies along the length of the connector 10. The tension in the connector 10, when the fibers are inserted into them, depends on the number and position of the slots 24 and 28.

Changing the distribution of voltage along the length of the connector 10 provides the possibility of sequence alignment, compressing and clamping the optical fibers. When the fibers are first injected into the connector 10, the ends of the fibers are centered relative to each other due to the size of the channel 20 to the fiber in the connector 10, which meet the ends of the fibers. After termination of the external forces that hold the connector 10 in the open position, the connector 10 provides the ability to recover around the fibers. When restoring a connector, the connector 10 is exerting a longitudinal compressive force on the fiber by pushing the ends of the fibers from each other. At the same time, when the connector 10 is restored, the ends 16 and 18 of the connector 10 to provide a clamping force on the fiber for fixing the fibers in the desired position in prig the party to one another. Compression forces and clamp acting on the fibers will be at least partly determined by the size, number and position of the slots 24 and 28. The connector 10 is made with the possibility that these efforts were small enough to avoid damage to the fibers.

It should be noted that in the above description of the stress distribution and sequence alignment, compression and clamping applicable mainly for the connector 40 (Figure 4). That is, the connector 40 creates elevated stress in the vicinity of their ends, when holding the fiber. But compression and clamp occurring in the fiber reinforced connector 40 in comparison with the connector 10 due to the presence of germosen parts 42.

Although the above description results in the preferred embodiment, it should be noted that in this invention, modifications and changes within the framework of the semantic content of the attached claims.

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.
