Detailed Description
Reference will now be made in detail to examples of inventive aspects of the present disclosure which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
According to the present disclosure, a number of different embodiments of support frames for supporting fiber optic adapters are described and illustrated. The support frames described and illustrated herein are configured to be mounted to existing fiber optic equipment fixtures and are configured to be usable with existing telecommunications equipment in providing further solutions in cable installation and management and fiber optic connectivity.
Referring to FIGS. 1-6, a telecommunications fixture (i.e., groove plate) 10 that is used to illustrate the inventive aspects of the different embodiments of the adapter support frames 100, 200, 300, 400, 500 of the present invention is shown. The telecommunications fixture 10 is designed for mounting a number of telecommunications equipment in a stacked arrangement. The fixture 10 depicted in the present disclosure may be used with a variety of telecommunications devices such as telecommunications closures. The fixture 10 depicted in the present disclosure defines a plurality of parallel hinge structures 12. The fixture hinge structures 12 are configured to receive the hinge structures of the telecommunications equipment for mounting. The hinge arrangement between the fixture 10 and the mounted equipment allow the equipment to be pivoted out of the way for accessing other equipment above or below thereof.
In FIGS. 1-6, the fixture 10 is shown as including mounted thereon a variety of telecommunications equipment such as a splice tray 14, a cable management tray 15, a first r
- 6 - embodiment of an adapter support frame (i.e., module) 100 according to the invention, and a second embodiment of an adapter support frame 200 according to the invention. A third embodiment of an adapter support frame 300 in accordance with the invention that can be mounted on the depicted fixture 10 is shown in FIGS. 28-39. A fourth embodiment of an adapter support frame 400 in accordance with the invention that can be mounted on the depicted fixture 10 is shown in FIG. 40 and a fifth embodiment of an adapter support frame 500 in accordance with the invention that can be mounted on the depicted fixture 10 is shown in FIG. 41.
Each hinge structure 12 of the fixture 10 defines a first socket 16 and a second socket 18. The first and second sockets 16, 18 are configured to receive first and second mounting pins 20, 22 of the hinge structures 24 of the telecommunications equipment that are designed to be mounted to the fixture 10. In the depicted hinge structure arrangement, the first and second mounting pins 20, 22 of the telecommunications equipment are inserted into or removed from the first and second sockets 16, 18 of the fixture hinge structures 12 in a single direction (i.e., rightwardly or leftwardly). During insertion of the equipment, a flexible tab 26 on the fixture hinge structure 12, which is lifted upwardly in receiving the equipment, elastically moves back to its previous position after the first and second pins 20, 22 have been inserted into the first and second sockets 16, 18, respectively. When in place, the tab 26 abuts a retaining portion 28 of the hinge structure 24 of the telecommunications equipment to prevent slidable removal of the equipment in a direction opposite the insertion direction. Please see FIG. 3.
It should be noted that the depicted hinge structure arrangement is only one example arrangement that can be used to pivotally and removably mount telecommunications equipment to the fixture 10. Other arrangements are possible.
Also, the telecommunications fixture or groove plate 10 depicted herein is simply one example fixture used for describing and illustrating the inventive aspects of the adapter support frames 100, 200, 300, 400, 500 of the present invention. The adapter support frames 100, 200, 300, 400, 500 of the present disclosure can be configured to be pivotally mounted to other types of fixtures 10.
Referring now to FIGS. 7-16, the first embodiment of the support frame 100 defines a front end 102, a rear end 104, a first side end 106, and a second side end 108. In the depicted embodiment of the support frame 100, the hinge structure 24 is formed at a rear wall 110 of the support frame 100. The hinge structure 24 defines a pivot axis 30 for the support frame 100. Thus, as shown, the first and second side ends 106, 108 of the support frame 100 are defined generally along the direction of the pivot axis 30 and the front and rear ends 102, 104 of the support frame 100 are defined in a direction generally transverse to the pivot axis 30.
Extending forwardly from the rear wall 110 is an adapter mount 112 that is configured for mounting fiber optic adapters 32 to the support frame 100. The adapter mount 112 defines a mounting wall 114 that is perpendicular to at least a portion of the rear wall 110. The mounting wall 114 includes at least one opening 116 for receiving a fiber optic adapter 32 in a direction along the pivot axis 30. In the depicted first embodiment of the support frame 100, the mounting wall 114 defines two separate openings 116 (see FIG. 7A) for receiving two fiber optic adapters 32. As will be described in further detail below, other numbers are possible.
Even though in the depicted examples of support frames of the present disclosure, the adapter mount 112 is shown as being located generally at the center of the support frame, generally halfway between the first side end 106 and the second side end 108, in other embodiments, the adapter mount 112 can be positioned off-center, closer to either the first side end 106 or the second side end 108. This configuration may be used in embodiments wherein the two cables that are connected through the mounted fiber optic adapters 32 have a different minimum bend radius.
Each fiber optic adapter 32 mounted to the support frame 100 defines a first connector receiving end 34 and a second connector receiving end 36. Each fiber optic adapter 32 is configured to optically align a first fiber optic connector received through the first connector receiving end 34 with a second fiber optic connector received through the second connector receiving end 36 along an alignment axis 38. As shown, when the fiber optic adapter 32 is mounted to the adapter mount 112, the alignment axis 38 is parallel to the pivot axis 30 of the support frame 100.
Even though in the depicted examples of support frames of the present disclosure, the mounting wall 114 of the adapter mount 112 is shown as being perpendicular to at least a portion of the rear wall 110 such that when the fiber optic adapter 32 is mounted to the adapter mount 112, the alignment axis 38 is parallel to the pivot axis 30 of the support frame 100, it should be noted that in other embodiments, the adapter mount 112 can be configured such that the alignment axis 38 of a mounted fiber optic adapter 32 is not parallel to the pivot axis 30. Again, this configuration may be used in embodiments wherein the two cables that are connected through the mounted fiber optic adapters 32 have different minimum bend radius. 0

In the depicted embodiment shown in FIGS. 7-16, the support frame 100 also includes top and bottom parallel reinforcement walls 118, 120 that extend from the rear wall 110 forwardly toward the adapter mount 112. The top and bottom reinforcement walls 118, 120 support the mounting wall 114 of the adapter mount 112 relative to the support frame 100. Each of the top and bottom parallel reinforcement walls 118, 120 defines a first side edge 122 and a second side edge 124. As shown, each reinforcement wall 118, 120 defines a tapering configuration wherein a width 126 of each wall 118, 120 extending between the first and second side edges 122, 124 decreases as it extends from the rear wall 110 toward the front end 102 of the support frame 100. As they taper, the first side edge 122 and the second side edge 124 of each reinforcement wall 118, 120 also define a curved configuration as they extend from the rear wall 110 forwardly.
The tapering configuration of the reinforcement walls 118, 120 allows the first and second connector receiving ends 34, 36 of the adapters 32 to be able to extend beyond the first and second side edges 122, 124 thereof, respectively. In this manner, the reinforcement walls 118, 120 allow access for mounting or removal of connectors to or from the fiber optic adapters 32 while providing reinforcement of the mounting wall 114 of the adapter mount 112 against any deflection with respect to the rear wall 110 or the hinge structure 24 of the support frame 100.
Even though adapter support frames 100, 200, 300 have been shown to include both a top and a bottom reinforcement wall, in other embodiments, the adapter support frames can be configured to have at least one reinforcement wall. For example, FIG. 40 illustrates the fourth embodiment of the adapter support frame 400 that includes features similar to the adapter support frame of FIGS. 7-16 with the exception of it defining a single reinforcement wall (e.g., a top reinforcement wall) 418. Similarly, FIG. 41 illustrates the fifth embodiment of the adapter support frame 500 that includes features similar to the adapter support frame of FIGS. 28-39 with the exception of it defining a single reinforcement wall (e.g., a bottom reinforcement wall) 520.
Referring now back to FIGS. 7-16, as shown, in the first embodiment of the support frame 100, the depicted fiber optic adapters 32 are SC adapters. In the depicted embodiment, the SC adapters 32 are removably mounted to the adapter mount 112 with flexible spring clips 40 known in the art. In other embodiments, the adapters 32 may be removably mounted with other methods such as with screw type fasteners. In other embodiments, the adapters 32 may be fixedly mounted to the adapter mount 112, such as by ultrasonic welding. .

As is known in the art, access to the ends 34, 36 of an SC type fiber optic adapter 32 is important in removing an SC type fiber optic connector from the adapter 32. An SC type connector normally includes an outer housing that has to be slidably moved with respect to an inner housing that is held by flexible latches of the SC adapter 32. Exposing the ends 34, 36 of the SC type adapter 32 provides access to the outer housing portion of the SC connector that may need to be grabbed and slid by a user in removing the connector.
As is also known in the art, an SC type adapter 32 is generally of a rectangular profile and defines a major dimension 42 and a minor dimension 44, wherein the major dimension 42 is greater than the minor dimension 44. In the depicted embodiment of the support frame 100, the openings 116 on the mounting wall 114 are configured such that the two SC fiber optic adapters 32 mounted to the support frame 100 are aligned along their major dimension 42. As such, a height 128 defined between the top and bottom reinforcement walls 118, 120 is similar in dimension to a minor dimension 44 defined by the SC fiber optic adapter 32. Since, the overall height 130 of the support frame is defined by the top and bottom
reinforcement walls 118, 120, the support frame 100 is able to provide a low profile by aligning the SC adapters 32 along their major dimension 42. This arrangement allows the support frame 100 to be mounted to existing fixtures such as the fixture 10 shown in FIGS. 1- 6 in a stacked arrangement along with other low profile equipment such as fiber optic splice trays 14 and maintain a dense environment.
The first embodiment of the support frame 100 also provides for cable management features for cables extending from the support frame 100. Connectorized cables that lead from the adapters 32 mounted on the adapter mount 112 are managed by a first cable management structure 132 adjacent the first side end 106 and a second cable management structure 134 adjacent the second side end 108 of the support frame 100. In the depicted embodiment, the first and second cable management structures 132, 134 are defined by cable management fingers 136. Cables extending from the support frame 100 may be lead to other telecommunications equipment such as those shown mounted to the telecommunications fixture 10 in FIGS. 1-6.
FIGS. 17-27 illustrate the second embodiment of the support frame 200 according to the invention. The second embodiment of the support frame 200 includes features similar to the first embodiment of the support frame 100 such as the reinforcement walls 218, 220 and the cable management fingers 236. However, instead of being configured for SC type fiber optic adapters 32, the second embodiment is configured for mounting LC type fiber optic adapters 32. In the depicted embodiment, four LC adapters 32 formed as an integral LC block 46 are mounted within a single opening 216 on the mounting wall 214 of the adapter mount 212. The opening 216 can be configured to accommodate other numbers. As known in the art, the LC adapter block 46 is mounted to the mounting wall 214 with a spring clip 40. Other methods of removable mounting such as using screw type fasteners or methods of fixedly mounting the adapters 32 are also contemplated.
Again, exposing the connector receiving ends 34, 36 of the LC adapters 32 is important since an LC connector defines a flexible latch that has to be accessed and pressed downwardly toward the main body of the connector before it can be freed from an LC adapter 32. Exposing the ends 34, 36 of the adapter 32 provides access to the latch portion or the trigger portion that activates the latch portion of an LC connector that is normally adjacent the adapter ends 34, 36.
FIGS. 28-39 illustrate the third embodiment of a support frame 300 according to the present invention. As in the second embodiment of the support frame 200, the third embodiment of the support frame 300 also includes features similar to the first embodiment of the support frame 100.
The third embodiment of the support frame 300 is configured with an opening 316 in the mounting wall 314 that is sized to receive an integral duplex SC adapter 32. Again, as in the first embodiment, the duplex SC adapter 32 is mounted such that the major dimensions 42 of the SC adapters 32 are aligned in a front to back direction, perpendicular to the pivot axis 30. This arrangement provides a low profile for the support frame 300 and allows the support frame 300 to be mounted to existing fixtures such as the fixture 10 shown in FIGS. 1-6 in a stacked arrangement along with other low profile equipment such as fiber optic splice trays 14.
Similar to the first and second embodiments, the third embodiment of the support frame 300 defines cable management structures 332, 334 for managing cables extending from the support frame 300. However, in the third embodiment of the support frame 300, the cable management structure 332/334 at each side end 306, 308 is configured such it that can lead connectorized cables extending from the fiber optic adapter 32 toward either the first and second side ends 306, 308 of the support frame 300 or toward the rear end 304 of the support frame 300. As shown, each cable management structure 332, 334 defines a first cable path 333 that leads toward the side ends 306, 308 of the support frame 300 and a second cable path 335 that leads toward the rear end 304 of the support frame 300. The cables are retained within the paths by cable management fingers 336. In addition to sharing with the first two embodiments a rear wall 310 supporting the hinge structure 24, the third embodiment of the support frame 300 additionally defines a front wall 311 that extends from the adapter mount 312 toward each of the first and second side ends 306, 308 of the support frame 300. The front wall 311 defines a curved portion 313 as it extends from the adapter mount 312 toward each of the cable management structures 332, 334 wherein the curved portion 313 is designed to provide bend radius protection for cables extending from the adapters 32 toward the cable management structures 332, 334. The wall 311 also forms portions of the first and second cable paths 333, 335 at the first and second side ends 306, 308 for directing cables away from the support frame 300.
Even though the above example embodiments of the support frames 100, 200, 300 have been described and illustrated as being usable with SC and LC type fiber optic adapters 32, it should be noted that the support frames of the present disclosure can be adapted to be used with various other different types of fiber optic adapters such as E2000, FC, MU, DIN, and ST style adapters.
Although in the foregoing description, terms such as "top", "bottom", "front", "back", "right", "left", "upper", and "lower" might have been used for ease of description and illustration, no restriction is intended by such use of the terms. The telecommunications devices described herein can be used in any orientation, depending upon the desired application.
Having described the preferred aspects and embodiments of the present invention, modifications and equivalents of the disclosed concepts may readily occur to one skilled in the art. However, it is intended that such modifications and equivalents be included within the scope of the claims which are appended hereto.
