Description

[Detailed description of the invention] This is a wiring board/connector holder combination device for connector holders and optical cables. The invention is a connector holder, an optical cable distribution board/connector holder combination device. It is related to In the optical cable communications industry, optical fiber connections are mechanical Use a connector or fuse the package connection slice and fiber end together I was going by that. In both cases, the fiber end faces are aligned . The end face of the optical fiber extending from the package slice covers the package slice. It is rolled up into a tray that has been organized. This type of configuration was introduced on November 16, 1982. Granted U.S. Patent No. 4,359,262 and Patented December 25, 1984 No. 4,489,830.

In the electrical cable and communications industry, telecommunications cables that are brought into the customer's premises The utility conductors are typically connected to the customer's internal network conductors by a distribution board. Retraction The cable extends to the distribution frame, where a jacket and other materials cover the core of the cable. Peel off a certain distance from the end face to reveal the core. insulated conductor The group extends from the core and connects to the input side connector terminal attached to the frame. Continued. The conductors of the internal network are connected to the connector terminals on the output side and Each connector line of the network is connected to each connector line of the input connector. typical The distribution board is a U.S. patent patented on July 14, 1981 in the name of B. T. Osborne. No. 4,278,315. The configuration of this distribution board is the internal network Remove and reinsert the workpiece conductor or allow the customer to disturb the input cable terminals. The terminals of these conductors are interchangeable.

In this way, telecommunications power cables are essentially the conductors of a customer's internal network. are simply connected in a straight line at the array section of the distribution board. Approximately 8 inches (2 Front side of a rectangular wiring board with a simple arrangement of about 0 cm) x 12 inches (30 cm) At most, it is possible to connect only about 500 terminals to the customer's internal network conductors. stomach. However, in the field of optical cables that have recently been developed, human cables and internal A simple distribution frame that connects directly to the end fiber of the network is not yet available. do not have. It is designed to be a practical optical cable distribution frame that makes high-density connections. That's because there aren't any. Additionally, this means that the method of making fiber optic connections requires a large amount of space. This is because it is essential.

The latter connects the incoming cable's optical fiber directly to the internal network's fiber. It is possible, but it is not sufficient. This means the connection is permanent and the customer is free because it cannot be moved to the internal network fiber and cannot be connected to the internal network fiber. It is. Therefore, a mechanical coupling connection is used between the input optical cable and the internal network. It would be a great benefit if possible. Mechanically bonded connections can be quickly connected or disconnected.

These connectors attached to input optical fibers and internal network fibers selectively remove input fibers and internal network fibers using You can check the connection level. However, mechanical connectors only connect individual fibers. requires an inordinate amount of time to complete. Therefore, the input optical fiber of the input connector Mechanical connectors may not be used to connect to internal network fiber optics. This is commercially unacceptable for cable installation companies.

To avoid this problem, traditional input optical fibers are called "pigtails" The structure was connected with the internal network optical fiber. Pigtil is Placed in series between each input optical fiber and the internal network fiber to connect each other do. A pigtail is manufactured in a factory and consists of a length of protection surrounding an optical fiber ( (called a pigtail fiber) and a mechanical component connected to one end of the bigtail fiber. It consists of a connector. The optical fiber of the input cable is a pigtail fiber. connected to the opposite end. This type of connection is better than using mechanical connectors. This will save you time. Such a connection action connects the optical fiber of the input cable. Optically connect the mechanical connector of the pigtail. These connectors are Easy for customers to connect internal network fiber optics be able to access it.

Arrangement for connecting the conventional input optical cables described above to the customer's internal network has become fairly accepted but its design array is still lacking in some respects. It was unsatisfactory. The input cable is a flexible cable with a connector installed in it. is connected to the pigtail fiber at a different location than the other arm. Easy and simple connection array The distribution board with which it was installed was not manufactured. For this purpose, pigtail fibers are basically It is necessary to protect the surrounding area. Protection allows free lateral movement of each fiber This is usually done by covering the tube with a loose tube. easy access for customers A common holder for connections and pigtails was proposed so that the However, these proposals The proposal eliminates the need to protect the outer circumference of the pigtail fiber, but only a small portion of it be handled by the cable installation company when a problem occurs with the connection or input fiber. easily accessible. As described in German Patent Publication No. 2735106 In one of these constructions, the housing is configured to move in and out of the housing. It has a tray attached by an axle. Manually powered optical fiber is housed in the tray. and connected to a pigtail fiber housed within the tray. This big The tail fiber runs from the tray to the pigtail connector attached to the back of the housing. It extends to Kuta. This prevents maintenance personnel from removing the tray from the housing surface. , and at the same time it is very difficult to see the connectors behind the housing. Howe See which input optical fiber behind the connector corresponds to which connector. is extremely difficult. On a different note, the width of the housing allows the tray to rotate around its axis. Such a gap is necessary. U.S. Pat. No. 4,729,203, the above German patent Structures similar to those described in the specification are disclosed. Disclosed in this US patent All pigtail connectors are attached to a tray in the housing. ing. The small number of pigtail connectors on each tray shown in this U.S. patent However, there is a problem in that the number of fiber connections in the housing is small. of this type Commercially available structures have fewer connectors and are smaller than 84 inches (213 cm). ) x 26 inch (66 cm) front area housing with internal network There are only about 250 input fibers connected to the fibers of Each tray is listed above Designed to increase the number of pigtail connections resulting in a tray The fibers must be installed in each tray attached to the housing housing that will be housed. Therefore, the activities of installers are restricted.

This invention has a high density of input optical fibers in an internal network, and Supplies a brainer type connector holder that allows easy access to the connector. Furthermore, the book The invention is a holder frame that allows high-density fiber connections and reduces the size of distribution boards.

Thus, for example, if the container is The minimum bend radius for a fiber coil is approximately 3 inches (approximately 8 mm) m), and the holder width is approximately 5.4 inches (14 cm). The mount area is Within this width of the holder, 12 connectors are provided within this width depending on the width of the connector. installed in the mounting area. As a result, each holder accommodates 12 input fibers in one Can be connected to two output fibers.

Additionally, the guard in the guard position protects the connector at the mounting area. moreover Importantly, when the holder is used in a distribution frame, the guard All optical fibers pass through the front of the distribution box and are routed from the end face to the front. There is no connection to that direction. Therefore, it does not cause any damage to human eyes. This gar Do can rotate in and out of guard position. The guard is moved from the guard position, and It can be restored.

The enclosure has two means for limiting the minimum bending radius of the fiber optic coil. The two means are used to limit the radius of two coil groups located at different locations. set apart.

The container includes one storage compartment. However, in a preferred configuration, this container has first and second housing compartments, and two fiber coil groups are housed in each compartment. To tolerate. In this configuration, a base is provided on the holder and the base is attached to the front end area. This section extends between the rear end region and the rear end region, and is divided into two sections on each side of the base. facing in the depth direction perpendicular to the surface. In this configuration, the distance between the leading and trailing regions is Distance is minimized – the two compartments are not placed on the same plane but between different base planes. It will be done. Furthermore, in a preferred configuration the two compartments are provided opposite each other and the host The holder base is usually a brainer, and the mounting surface is on one side of this holder base. is provided and faces in the depth direction with respect to the surface of the holder. The latter preferred configuration The connector holder size has been optimized in all directions, allowing one or both connectors to be are mounted at the same depth in the same area in both compartments. As a result, all directions are minimized. The holder can accommodate up to 12 connectors.

In the fully operating position of the holder, the latch The finger projections 96 of 89 enter recesses 95 in the front of the holder. The coil winding operation is completed. After the input hole 24 of the holder is clicked, the holder slides into the frame. As the vertical channel 100 containing the tube 110 is approached, the tube containing The size of the coils of tube 110 in compartment 20 can vary suitably. this The excess tube extending from the holder is removed while the holder enters the frame. This is because the length is received into the tube receiving compartment 20 through the input hole 24. other All tubes 110 have optical fibers connected to pigtails and mounting locations. Connected to the associated holder 10 in a similar manner to the connector mount 62 placed on the It will be done. These holders are placed in the left bank of holder receptacles as required. Hol In the holder 10a on the opposite side of the holder 10, the right channel 100 (see FIG. 13) Pigtail optical fiber 1 to the customer's internal network optical fiber accommodated in 28 are connected sequentially. These optical fibers are similar to those described in holder 10. the excess length of the tube 126 in the tube receiving compartment 20. As each holder rotates, the holder 10a is inserted into the right side of the holder receiver 78. It will be done.

In the final assembly of holders 10 and 10a to bank 78, FIGS. As shown in FIG. 0, the tube 110 is attached to the rear end of the connector mount 62 of the holder optically connected to the In the holder 10a, the output from the tube 126 or In this case, the distribution fiber 124 is wound around the fiber receiving compartment 22a, and the distribution fiber 124 is wound into the fiber receiving compartment 22a, Connected to pigtail 128 using splices placed on price block 50. It will be done. The connector connected to the big tail optical fiber 128 is attached to the holder 10a. It is supported by a mounted connector mount 62a.

The bank 78 on the left side of the receiver that accommodates the holder 10 is located on the input communication cable side in the distribution board. the interface area, while the right bank of the receptacle that houses the holder 10a. is the frame output or the customer internal network side, and the network distribution optical connected directly to the fiber. Store holders 10 and 10a in the operating position on the wiring board. Then, the guard 7o is almost continuously connected to the adjacent guard perpendicular to the front surface. the fiber or tube containing the fiber should be secured in the connector guard position. It will no longer stick out from the surface. In this way, the guard 70 is connected to the connector mount. 62 is eye-safe if not connected to a patch cord (about this (described below). Guards also If the holder is placed next to the empty holder receptacle 78, a special guard hinge Because of the interference between the projection 74 and the frame member, it is fixed at the guard position.

Includes tube protection fibers (not shown) and connectors 134 at each end. Connect the connector in the connector mount 62 to the mount 6 using the patch cord 130. It is a simple matter to selectively connect the connectors in 2a. front access The selection is made by pulling out the two banks of holders 1o and 10a into position. Ru. After pulling it out to the access position, place the selected holder on the guide rail 90. latches 89 engage the rear recesses 95. of the holder Guard 70 is free and can be rotated to an unguarded position. Place the guard 70 in the lower non-gauge position.

Connect to the tip of the selected connector. The access position of the holder 10a is as an example. For example, this is indicated by the position of the dashed line in FIG.

To avoid confusion and difficulty during maintenance and repositioning of patch cords, Consideration is given to ensure that there are no fibers or tubes extending forward of the combination with the . This problem is solved by having tubes 110 and 126 in vertical channel 100; solved by extending directly into the input hole 24 of the tube receiving compartment 20 (the first (See Figures 9 and 20). These manual holes 24 are , adjacent the vertical channel 100. Furthermore, each patch cord 130 is and placed in the fiber receiving channel 85 between the intermediate walls 84 as shown in FIG. Accordingly, the connector 134 is disposed between the connectors 134. Each group of patch cords is Through the fence hooks 104 on each intermediate wall 84, it is passed through the rear between the intermediate walls 84 and positioned. Placed behind the top of the patch cord loop supporting the means bracket 136 The arcuate channel 102 is rotated so that the radius of bend is minimized. It is passed almost horizontally. Support bracket 136 extends between sidewalls 184 and supports pigtails. It's a little far away from the aisle. Each patch cord is attached to a support bracket 136. Extends freely downwards in loop 132 at the rear, where the patch cord is too long. will be accommodated in Fiber receiving channel 85 has sufficient width to accommodate patch cord fibers. Ensure that the loop 132 of the fiber is greater than or equal to the desired minimum target radius.

Excessive length of the patch cord in loop 132 should be When later moved, by movement of the patch cord past the support bracket 136. handle. Furthermore, using the patch cords arranged as described above, Changing the patch cord connections to the holders for each bank of the Easily implemented by changing the relative position of the connectors in the holder using will be carried out.

As mentioned above, each holder 10 and 10a is compact in size, and The fibers connected to the connectors in the card can be multiplexed. As mentioned in the first example There are twelve connector mounting positions for each holder. this big maun position by bringing the mounting area to the front end area of the holder and opening the tube receiving compartment. 2o and the fiber receiving compartment 22, i.e. the two compartments are the mounting area and the holder. The holder width area between the rear end area reduces the holder to a compact size. This was made possible by making it possible. In other words, the holder No additional width is required beyond that required for the containment compartment to accommodate the area. . From this, the width of the holder maximizes the number of connectors that can be mounted on the holder. Meanwhile, minimize the width of the holder. Furthermore, the holder length has two tube receiving compartments. 20 and the fiber receiving compartment 22 are adjacent in the length or width direction of the holder. , are located adjacent to each other in the depth direction in the holder, so that they are minimized.

Furthermore, since the connector mount 62 and the connector are on the same plane as the receiving compartment of the holder, The depth of the holder can be reduced. Therefore, the depth of the holder is equal to or greater than the width of the side wall 18. It will never be on top. The holder size reduced in this way has a length of 11 ．． 8 inches (30cm), width 5.4 inches (13.7cm), depth 0.　 It was 88 inches (2.2 cm). This enables the first embodiment as described above.

A total of 1440 connectors could be accommodated in the front area of the router. Therefore, a total of 720 inputs power fibers are connected from one bank to other banks and the customer's internal network. It will be done.

Another benefit of this configuration is that the tube receiving compartment 20 is completely separate from the fiber receiving compartment 22. The bare flap in the tube-receiving compartment is The tube can be moved within the compartment without damaging the fibers.

In addition, the fibers in the fiber accommodation section 22 are not moved or damaged. The holder is completely removed by unwinding the coil and removing the tube from the holder. It is then removed from the frame and placed on the work table 112. Therefore, this Under these circumstances, avoid damaging the fiber from the rolled tube. I can do it.

The width of the first embodiment described above is 26 inches (66 cm) and the depth is 84 inches (2133 cm). cm) distribution board dimensions are used for purposes where the frame has an input bank and an output bank. If not, it can be reduced. In particular, holders 10 and 10a are Frames used only for power fibers are used very efficiently.
