DETAILED DESCRIPTION of embodiments

These drawings represent various embodiments of the capture device and splicing of optical fibers. The terms "capture", "splice", "clip" or "connection" can be applied to the devices and are not in this case, mutually exclusive, because the devices and methods of the present invention can be used for the applications of capture-to-fiber clamp fiber splicing optical fibers and/or connection of optical fibers. The term "splicing" should not be construed in a limiting sense, since the elements shown in the various embodiments, execution, can really allow removing the optical fiber.

Figa and 1B represent two component capture device and splicing optical fibers in accordance with the first variant is Tom the implementation of the present invention, krasivuyu item 110 (Figa) and exposing the tip 150 (Pigv). On Figa item 110 is shown in its bent state. In this exemplary flexed item 110 provides the initial axial alignment of the bonded optical fibers. Item 110 includes a first element 112 and the second element 114 is formed, for example, from a sheet of material 111 (see Figa), pivotally fastened to the first ends of each element, which is shown here as the hinge section 116. Item 110 additionally includes separate areas splicing and/or compression. In one exemplary embodiment of one or more slots, such as slot 141 may be performed to form a separate area splicing/compression. Alternatively, a separate zone splicing/compression can be formed by reducing the thickness of the sheets 111 between zones splicing/compression. It also provides the capture area 120, which includes a first gripping portion 122 and the second gripping portion 124 located on the first and second inner parts of each element (see, for example. Fig.2D). The capture area 120 is adapted to receive an optical fiber in her exciting part. The optical fiber can be inserted into the element 110 through the channels a and 121b. In an exemplary embodiment of the present invention, the gripper 110, as is shown in the closed (powered or concatenated) condition, can make considerable efforts to the outer perimeter of the optical fibers (fibres), located in the capture area.

The size of the sheet 111 (see, for example, Figa-2C) may vary significantly depending on the application. Item 110 may be made of sheet 111 of deformable material, preferably a ductile metal, such as aluminum. For example, this may be an aluminum alloy, commonly known as "3003", which has zero carbon content and hardness Brinell between 23 and 32. Another acceptable alloy called "1100" and has a carbon content of 0, H14 or n. Allowable stretch resistance varies from 35 to 115 megapascals. As the sheet material 111 can be used other metals and alloys or laminates of them. Such metals include copper, tin, zinc, lead, indium, gold, and alloys of them. In addition, the sheet 111 can be used a polymeric material, transparent or opaque. Suitable polymers are polyethylene terephthalate (polyethylene terephthalate), polyethylene terephthalate glycol, acetate, polycarbonate, polyethersulfone, peek, polyetherimide, polyvinylidene fluoride, polysulfone and complex sobolifera, such as VIVAK (trademark of Sheffield Plastics, Inc., Sheffield, Massachusetts).

As seen on Figa and 2D, ornery section 116 can be formed on the outer surface of the sheet 111, increasing, in General, the length of the sheet 111. The hinge section 116 may have a centrally located groove, which may be formed from the area of reduced thickness which defines a hinge separating the sheet 111 on two identical plastination element or legs 112 and 114. Such a hinge may be formed as described in U.S. patent No. 5159653. When folded item 110 is made with possibility of installation in a device for splicing optical fibers, such as a mechanical device for splicing optical fibers FIBRLOK II™. Item 110 may also be implemented in other devices for splicing optical fibers and optical connectors, as will be obvious to someone who has ordinary skill in the art to which the present invention relates.

FIGU is a perspective front view of an exemplary tip 150. The tip 150 is executed in the possibility of coupling with item 110 that provides the installation part 110 in the closed or actuated condition. In accordance with exemplary embodiments of the implementation of the present invention, because the component 110 includes separate zones of compression, the tip 150 is made so that it contains a separate actuating mechanisms, such as region region 160 and 170, which are connected with a part 155 of the housing. Because Nikon is CNIC 150 is engaged with the workpiece 110, different compression zones can be activated/closed at different points in time. A more detailed description of the structure of an exemplary tip below.

On Figa presents a top view of an exemplary part 110A in the expanded state. Item 110A includes a slot 141 which defines a separate zone 185 and 187 splicing/compression. The slot 141 may be cut in the sheet 111 with one hand so that it fits to the center of the part, where you may be located the hinge section 116. Item 110A includes sheet 111 material having elements 112 and 114 pivotally connected via a hinge section 116, such as described above. Element 112 includes a gripping portion or groove 192 and 193, which may be in the form of v-shaped grooves, or may have some other polygonal shape, depending on the type(s) of the optical fiber, which must be captured and/or spliced. Grooves 192 and 193 can be made so that have the same shape or different shapes depending on the application. As an alternative to the grooves 192 and 193 can be pre-machined, as described in the application U.S. No. 2005-0063645-A1. Element 114 includes a gripping portion 194 and 195 (located opposite the gripping parts 192 and 193, respectively), which can be pre-machined, designed as v-shaped grooves or made in some other megapoli the Oh form. Grooves 194 and 195 can be made so that have the same shape or different shapes depending on the application. For example, as shown in Fig.2D, end view of part 110A in the open position for placement of an optical fiber, the first exciting part 122 and the second engaging portion 124 can be made so that you have v-shaped grooves.

In an alternative embodiment, the details 110S presented on Figs, slot s can partly take place in the sheet 111 with one hand, not cutting the portion of the groove of the pick-up area.

Item 110A may be used for splicing optical fibers of any type, such as conventional optical fiber type glass-glass-polymer ("GGP") (described in U.S. patent No. Re.36146), standard fiber optic, made on the basis of glass, POF (plastic optical fiber) and TECS fiber (glass with technically superior coating). These optical fibers may be single mode and multimode optical fibers and may have a standard diameter (including protective coatings), such as about 125 microns (without protective coating or protective coating), 250 μm outer diameter and/or 900 μm outer diameter, and non-standard diameters, which can be less than 125 microns, between 125 μm and 900 μm and/or greater than 900 microns, or others. In one exemplary alternative embodiment, the grooves I 194 are made so as that forms the first diameter (or gauge groove)when the device is powered and grooves 193 and 195 machined in advance so that they form a second diameter (or gauge groove)when the device is powered. The second diameter (or gauge grooves) may be the same or different from the first diameter (or gauge grooves). In one exemplary embodiment, for example, when splicing optical fibers coated with silicon dioxide, the groove 192 may have a v-shape, and the groove 194 may be absent, while the grooves 193 and 195 may be made so that they allow clamping the optical fiber with a protective shell of larger diameter. In addition, one or more areas of capture elements 112 and 114 can optionally further include one or more cones or grooves 132A-132d and 134a-134d, forming the entry area of the fiber.

As shown in Figa, part 110A is made with one slot, such as slot 141, which may be cut in the item element 112 or 114 (in this figure the slot 141 is made in the element 112). The slot or slots may be used for the formation of distinct zones of compression (when the item 110A is in a straightened state), the zone 185 may provide a zone of splicing and area 187 may provide a zone of compression buffer (protective coating of the fiber), or Vice versa. Thisway, area 185 splicing can be opened or closed regardless of the zone 187 compression buffer, or Vice versa, and at another time in the connection sequence. For example, when splicing optical fiber with ferrule with end-to-end fiber place of splicing optical fibers may be located in the zone 185 (also called area splicing), and target optical fiber, a protective layer may be held in place using zone 187 compression. For example, clamping grooves 193 and 195 may be designed to hold the protective layer of the optical fiber (in the closed or actuated condition) with a diameter of 250 μm. This clip can keep the optical fiber, when the element is fully closed.

In an alternative embodiment, shown in Figv, 110V item is a structure with two cuts (including cuts a and 141b formed in the sheet 111 opposite the hinge 116 from each other), providing education zones 185 and 187. In addition, designs with numerous slots can provide various efforts depending on the application. Of course, as will be obvious to anyone with ordinary skills in the field to which the present invention, a different number of slots may also be used without going beyond the scope from which retene.

In an additional alternative embodiment, the zone 185 and 187 may be determined by refinement of the thickness of the material sheet 111 separating zone splicing and/or compression. For example, the separation zones splicing and/or compression can be achieved by reducing the thickness of the sheet material on 50-90% of its original thickness in the area between the zones, depending on the type of sheet material used.

These exemplary configurations provide different levels of compression optical fiber, which is located in each zone. In one exemplary embodiment, the connector is a short segment of optical fiber, fixed at one end, is fixed in the sleeve and passes from the bushing in the center of the zone splicing (called here "okolcovannaya part of the optical fiber"), can be connected to the terminal of the optical fiber, whereby it may be actuated (closed) area of the splice, then driven area of compression (or capture), which provides for the termination of optical fiber in place. This sequence splicing can ensure sufficient optical contact between the end faces of the optical fibers. Alternatively, for precise alignment of two optical fibers in the area of the splice can be made small by the level of compression, instead of the ones with the to increase the overall holding capacity of the optical fiber, it is in the zone of compression can be applied to a larger level of compressive force. After actuation zone compression bonding can be completed using the full operationalization of the area of the splice. It is noted that the term "closed" or "powered" is intended to indicate the position when the gripping part have a significant compressive efforts on the outer part of the optical fiber which is spliced/captured/retained. Thus, at least some of the retaining force may be applied to the optical fiber or coating of the fiber, without the device in action completely.

Thus, in accordance with exemplary embodiments of the implementation of the present invention, given this mechanism, full actuation of one zone of compression can be achieved regardless of the actuation of the other zones of compression, for example, before, at the same time or after.

As previously mentioned, in accordance with exemplary embodiments of the implementation of the present invention, the tip 150 (also referred to here as the acting tip) can be used to actuate the parts 110, 110A, 110, 110S. The tip 150 may be made of rigid mA the materials, such as metals or plastics. For example, the tip 150 may be fabricated by casting under pressure. Other suitable materials will be apparent to someone who has ordinary skill in the technical field to which the present description.

On Figa representing a side view cross-section outer surface, the tip 150 includes a portion 155 of the housing, which extends along the tip and connects the first gripping mechanism 160 and the second gripping mechanism 170. In the exemplary configuration shown in Figa, the tip 150 can optionally further include one or more latches, such as latches 156 and 157, located on the outer surface of one or both of the first gripping mechanism 160 and the second gripping mechanism 170. The lock(s) can be used to set in a certain position and engagement of the tip with a connector or krasivyi element (shown in more detail Figa-5C). Depending on the choice of the tip 150 may be performed two or more tabs.

The Cam 162 includes a first Cam section 161. During closing device for capturing and splicing petals item capture and splicing can rely on section 161, and the petals remain in the open position (i.e., the petals of the element is not biased toward each other, thus allowing to enter the optical fiber). The Cam 162 further includes a first transition area 164 and the second transition area 166. The Cam 171 includes a first Cam section 176, and the first transition area 172 and the second transition area 173. As can be judged by referring to end cross-sectional sample of the tip 150 presented on Figs and 3D transition area 164 may be made so as to gradually bring in the action area splicing parts 110, 110A, 110, 110S to actuate the compression zones of the protective layer of the fiber, in this example, a transition area 164 is located in a lower position (in relation to part 155 of the body) on the elements of the tip (or legs) 151 and 152, than a transitional space 172. In addition, the gradual compression of the part (for example, in the area of 185) may be provided by cutting the protrusion of the transition platform 164. Also a transitional space 172 is not in contact with the workpiece 110, 110A, 110, 110S up until eretna Playground 166 will not come into contact with the element splicing. Thus, as the tip 150 is engaged with the workpiece 110, 110A, 110, 110S, the Cams 162 and 171 can slide along the petals of elements 112 and 114, compressing them to each other. In an exemplary embodiment, the rounded edges along the outer surface of the petals 112 and 114 parts (see, for example. Figs) can further contribute to the elimination of the mechanical beating.

In accordance with an alternative implementation of the present invention, the tip 150 may optionally include additional transitional pieces for one or both of the Cams 162 and 171.

On Figa-4D shows the approximate sequence of the actuation element 210 splicing using tip 250. This example assumes that okantovannoy fiber inserted into the gripping portion of the area 285 splicing, and the buffer portion connected terminal of the optical fiber (not shown) inserted into the gripping portion of the area 287 compression. On Figa representing the device in disassembled form, the tip 250 is not in engagement with the workpiece 210. On the side view cross-section Figa shows a single (or double) the slot 241, which defines the zones 285 and 287 parts 210.

Figv shows the position when the tip 250 is shifted in the direction of workpiece 210 in the direction indicated by the arrow 205, and is in contact with the first Cams 61 and 176, so in the area of 285 splicing can be carried out prior optical contact ends okontsevanie optical fiber and connected terminal of the optical fiber. On FIGU you can see that the beginning of the transition areas 164 of the Cam coincides with the upper part of the zone 285 splicing.

The final move can be performed manually, and preferably with the use of the tool. In particular, an exemplary tool could place the device alignment and capture of the optical fiber splicing device or connector) into the installation slot, which is part of the base of the tool. The base of the instrument can be made with the possibility of placing on a flat surface and/or retention in the hand of the operator. The capture device and splicing of optical fibers housed in the socket so that the impacting tip would be in the upper position (as shown in Figa-5C). This tool can also be the arm, the shoulder of which is attached to the base for rotation in the bracket, and extends from the attachment point to the end, which is beyond the installation slot. The end of the lever arm may be made so that you can lean against it with your thumb or finger and create the force applied to it, peremeshautsa towards the base of the instrument. At a point between the attachment point of the lever arm on the base and the end of the lever arm directly in line with the alignment slot of the device may be a third point, which may be approximately the size of the acting tip. This third point or switching point, comes in contact with the upper part of the acting tip as the lever is rotated towards the base of the instrument. When power is attached to this lever arm, the tip of the pressing device in the direction indicated by arrow 205. This lever arm may also have a limiter that affecting the tip was not overly powered. After actuating the lever arm is rotated from the working area and the device is removed from the tool.

As the tip 250 is continuously moved in the direction of the arrow 205, for example, using the lever tool. Pigs shows that the transition area 164 of the Cam fully comes into contact with an area of 285 before entering the contact zone 287, which has not yet acted transition area 172 of the Cam. Using this action splicing okontsevanie optical fiber connected with the optical fiber ends. Fig.4D shows full actuation parts 210, when the area 285 is closed by the Cam 162 and the area 287 is closed by the Cam 171. In the end, as the area 287 fully powered, the connected optical fiber is securely captured in the component 210 that provides better holding capacity of the connector.

Another illustration of the actuation element 210 is shown on the types of cross-section Figa-5C, where the item 210 is located at the base 290, which may be part of an optical connector or a separate device splicing. In this example, again assume that okantovannoy optical fiber and connected optical fiber (not shown) inserted into the gripping portion of the area 285 splicing and the buffer portion of the joined optical fiber was placed in the gripping part of the zone 287 compression. On Figa item 210 is located on the frame 292 base 290. In this exemplary embodiment, the pressure plate 292 may optionally have a slot 296 in which is placed and held by a hinge section 216 part 210. The base 290 further includes a slot 295 in order to take elements 251 and 252 of the tip, and the tabs 294 base, designed to capture (or fixing in place) stoppers 256 and 257 of the tip. The construction of the part 210 and the tip 250 is similar to the structures described above.

On Figa the tip 250 is moved as shown by arrow 205 direction until reaching the position in which the brakes 257 securely grips the 294 base. In an exemplary embodiment, this position also corresponds to the beginning of entering into the engagement elements (or feet) 212 and 214 zone 285 through transition areas 164 of the Cam. From this position, as shown in Figv, upon further movement of the handpiece 250 in the direction of arrow 205 area 285 (here designed as area splicing) is actuated (closed), because the elements 212 and 214 zone 285 are pushed towards each other by transition areas 164 of the Cam, while the area 287 (here performed as a zone of compression buffer) remains in a folded open. In this exemplary embodiment, the area 285 further includes a gripping region 120b, which has a v-shaped configuration of the groove to perform the join okontsevanie optical fiber connected to the optical fiber. In addition, the area 287 includes a gripping region 120A, which is made to capture or compression buffer part of the connected optical fibers.

With continued movement of the tip 250 in the direction indicated by the arrow 205 (part 210), Figs illustrates the position of the fully powered as zones 285 and zone 287. In this exemplary embodiment, the full actuation corresponds to the position of the stoppers 256, which are fixed FIC is torami 294 base 290. At this point the tip is fixed based on the 290, but can be moved traction force in the direction opposite that indicated by the arrow 205. In an alternative embodiment, the distance between the stoppers 256 and 257 of the tip can be changed to specify a greater or less distance, determines the conversion element in the action, which will provide a more slow or fast bring it into action. Thus, in accordance with an exemplary alternative implementation of the device for gripping and splicing optical fibers can provide independent capture/splicing for different parts of the optical fibers (fibres), which are captured/spliced.

As will be obvious to someone with ordinary skill in the art to which the present invention relates, serial and/or gradual compression of the various zones of the element clamp/splice can be performed using various means. For example, affecting the tip can be performed with one Cam and an integral part of the elements 212 and 214 zone 287 can have a smaller length (in the direction from the hinge area)than the elements 212 and 214 zone 285. Thus, by moving the tip 250 in the side wall of the workpiece 210 area 285 will be in contact with the Cam before you begin kontaktira the AMB with the Cam area 287. In this way the area 285 will be powered regardless of the zone 287 and to actuate the zone 287. Alternatively, the area of capture zones 285 and 287 can be designed differently, to apply different levels of compression to the outer perimeter of the optical fibers (fibres), held here, invoking, therefore, the actuation of the various parts of the optical fibers (fibres) at different points in time. In an additional alternative embodiment, affecting the handpiece can be divided into two or more separate acting tips, which can be slipped onto different parts of the clamping element and splicing at different points in time. In another alternative embodiment, affecting the tip can be made capable of sliding in a direction parallel to the axis of the optical fiber, making affecting the first tip is in contact with the first zone of compression, and then upon further movement in the direction parallel to the axis of the optical fiber, resulting in a second zone of compression.

In accordance with another exemplary variant of execution affecting the tip can be designed to provide either symmetrical or asymmetrical Cam interaction. For example, on Figa shows a symmetric con who horatia, where the tip 250 (like shown above) contains the Cams 162 and 171 on both elements 251 and 252 of the tip. As an alternative to Figv presents the handpiece 350 with Cams 362 and 371, which are made only on the element 353 tip. In another alternative embodiment (not shown) of the Cam 362 can be performed on the element 351 tip and Cam 371 can be performed on the element 352 tip. Other alternative configurations will be apparent to anyone with ordinary skill in the art to which the present invention relates.

As mentioned above, item 110 can be implemented in many devices splicing optical fibers and optical connectors. Thus, an exemplary fiber connector 400 shown in Fig.7. In this design the item 210 is placed in the base connector 290. As discussed above, okantovannoy optical fiber, for example, the tip 430 having an optical fiber 432 may be placed within the zone 285 to full actuation. Tip 430 may be inserted into the channel 297 base 290. The terminal end of which is connected an optical fiber (not shown) can be inserted into the connector 400 through the centering channel 298, through the open area of capture within the zone 287 compression up until couples with the optical fiber 432 NR the three zones 285. In accordance with one or more exemplary embodiments of execution described above, bringing the device in action can be performed by moving the tip 250 to the workpiece 210. In this exemplary configuration, the Cam 162 actuates an area of 285 before the Cam 171 actuates an area of 287. In an alternative embodiment, the tip 250 may be performed so that the Cam 171 trigger zone 287 at the same time or prior to the actuation zone 285 Cam 162. As will be apparent to anyone with ordinary skills in the art to which the present invention, the device 400 may be designed for splicing/capture other fibers, such as two terminal optical fibers.

In addition, as will be obvious to anyone with ordinary skills in the field of technology related to the present description, in alternative embodiments, the steps described here are devices for capturing and splicing can be used in fiber optic devices 4×4 FIBRLOK™ and Multifiber FIBRLOK™ (manufactured by 3M).

In an additional alternative embodiment, the item 110 may be placed in the body of the capture device and splicing optical fibers and may use one or more acting tips, which can separately close the AC is blowing section (area) details. For example, the length of the optical fiber in a protective sheath known diameter (for example, a section of flexible fiber) can be cleaved and polished first end or the normal optical connector (for example, optical connector, ST, LC or FC type)attached to the first end. The other (second) end of the segment of the flexible optical fiber may be located within the zone of compression of the protective shell part 110. This second end of the optical fiber can be stripped from the protective coating, and the bare portion may extend partially into the area splicing of the same part. The first tip may trigger the compression area of the protective sheath, which causes the clamp coated optical fiber, while the second lug can be used later for actuation zone splicing optical fiber when it is set to the target optical fiber. As a result, the item 110 may receive a portion of the terminated fiber-optic cable that would provide quick installation in the field (for example, where the installer prepares only the second optical fiber (i.e. the target fiber) for zone splicing to connect fiber optic cable to the second optical fiber).

Another exemplary embodiment of which is illustrated in Fig, which shows the t device 500 to capture and splicing of optical fibers, which includes item 510 and exposing the tip 550. In this exemplary embodiment, the item 510 includes three distinct zones of compression zone 585 splicing, the first zone 587 capture a protective shell and a second area 588 capture the containment. Item 510 may optionally include one or more grooves/ports 532, 534, 535, 536, forming the inlet area of the receiving optical fiber. In variants of execution where the slits A and B do not reach the areas of the groove part 510, the inlet region 535 and 536 of the reception optical fiber can be excluded.

One or more grooves 594, 595 and 596 may be formed in a part 510 as a v-shaped groove or grooves of other shapes, similar to those described above. In this exemplary embodiment of the invention the groove 594 designed in such a way that has a first diameter (or gauge grooves) when powered device and grooves 595 and 596 machined for the formation of the second diameter (or gauge groove)when the device is powered. The second diameter (or gauge grooves) may be the same or different from the first diameter (or gauge grooves), in one exemplary embodiment, for example, when splicing optical fibers with a coating of silicon dioxide groove 594 may be v-shaped to grip the bare optical fiber, and grooves 595, 596 could the t to be executed with the ability to capture the bonded optical fibers in a protective sheath. Item 510 may be powered by tip 550, which may include three separate mechanism 560, 570 and 580 actuation. For example, as shown in Fig tip 550 may include three separate Cam - Cam 562 for actuation zone 585, Cam 574 for actuation zone 587 and Cam 577 for actuation zone 588. In an exemplary configuration, the tip 550 may be designed so that the Cam 562 trigger zone 585 at the same time or prior to the actuation zones 587 and 588 Cams 574 and 577, respectively. As will be obvious to anyone with ordinary skill in the technical field to which the present invention, the device 500 may be designed for splicing/capture any type of optical fiber.

As described above, a device for gripping and splicing of the present invention can be performed with multiple zones of capture/splice that provides different levels of impact that can be transmitted on the optical fiber located in a certain area and at a certain place in the sequence of the splice.

Because fiber optics are used deep into the underground and gained access to the networks, the benefits of such products mechanical connection can be used in the technology of Fiber in d is m/Desk/building/enterprise" (FTTX technology). The device of the present invention can be used in the mounting hardware, which provides ease of use when performing a large number of splices and connections, especially where labour costs are more expensive.
