The present disclosure relates generally to closures, such as for fiber optic cable connections, and more specifically to improved organizer assemblies for butt closures.
Certain closures, also referred to as “butt” or “domed” closures, are utilized in outdoor environments to facilitate the connection of transmission cables such as fiber optic cables. The cables enter the closure through a sealed base, and connection of the cable elements occurs within the closure. In the case of fiber optic cables, spliced-together optical fibers are held within the closure.
Many fiber organizer assemblies utilized in known butt closures generally have edges that can cause buffer tubes to kink if they are pulled over these edges. Further, in many cases, trays of the organizer assemblies must be held in the vertical or up position while other trays are being populated with fiber and while splicing is being done. Still further, splice modules utilized in such trays provide limited flexibility with respect to the types of splices and/or other components that can be held therein.
Accordingly, improved organizer assemblies for use with butt closures would be advantageous. Specifically, organizer assemblies which address one of more of the above-stated deficiencies would be advantageous.
Aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
In accordance with one embodiment, an organizer assembly for a butt closure is provided. The organizer assembly defines a mutually orthogonal coordinate system which includes a longitudinal axis, a lateral axis, and a transverse axis. The organizer assembly includes a primary basket extending along the longitudinal axis between a first open end and a second closed end, the primary basket defining an interior. The organizer assembly further includes a bracket assembly extending along the transverse axis at the first open end of the basket, the bracket assembly including a plurality of hinge assemblies. The organizer assembly further includes a plurality of organizer trays, each of the plurality of organizer trays rotatably connectable to the bracket assembly at one of the plurality of hinge assemblies. Each of the plurality of organizer trays is rotatable between a first position wherein the organizer tray is aligned along the longitudinal axis and a second position wherein the organizer tray is aligned along the transverse axis.
In accordance with some embodiments, each of the plurality of organizer trays includes a plurality of positioning slots and a positioning tab. The positioning tab of one of the plurality of organizer trays is inserted in one of the plurality of positioning slots of a neighboring organizer tray when the plurality of organizer trays is in the first position. The positioning tab of the one of the plurality of organizer trays is inserted in another one of the plurality of positioning slots of the neighboring organizer tray when the plurality of organizer trays is in the second position.
In accordance with other embodiments, the organizer assembly further includes a plurality of splice modules removably connected within each of the plurality of organizer trays. Each of the plurality of splice modules includes a base and a plurality of partitions extending from the base. Neighboring partitions of the plurality of partitions define channels therebetween, each channel defining a longitudinal channel axis. Each of the plurality of splice modules further includes one or more arms extending from each neighboring partition into each channel defined by the neighboring partition at an angle to the longitudinal channel axis. The one or more arms extending into a channel from a first partition of the neighboring partitions extend in a direction opposite the direction of the one or more arms extending into the channel from a second partition of the neighboring partitions.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

Each organizer tray 200 is rotatably connectable, and thus may be rotatably connected, to the bracket assembly 140, such as to one of the plurality of hinge assemblies 144. Each organizer tray 200 may be rotatable, such as between a first position wherein the organizer tray 200 is aligned along the longitudinal axis 102 (as shown in
For example, each organizer tray 200 may include a main body 202. Main body 202 may, for example, include a base wall 204, a first sidewall 206, a second sidewall 208, and a front wall 210, and may further define a rear end 212. First sidewall 206 and second sidewall 208 may be spaced apart along the lateral axis 104. Front wall 210 and rear end 212 may be spaced apart (such as along the longitudinal axis 102 when in the first position). The rear end 212 may be an open end, as shown, such that cables 42 or transmission elements thereof being directed along and parallel to the longitudinal axis 102 can enter or exit an interior 214 of the organizer tray 200 through the rear end 212, when the organizer tray 200 is in the first position. The front wall 210 and sidewalls 206, 208 may define a closed end and closed sides.
In some embodiments, a plurality of apertures 216 may be defined in the base wall 204, such as at the rear end 212. Each aperture 216 may be utilized to secure a cable 42 (or transmission element thereof) directly to the base wall 204 and organizer tray 200 thereof, such as using a suitable zip-tie or other suitable fastener. Notably, no additional cable/transmission element securement components are included on the organizer tray 200.
Organizer tray 200 may further include one or more connector arms 220 which may extend from the main body 202. For example, each connector arm 220 may extend from the base wall 204, such as along the transverse axis 106 when in the first position. The connector arms 220 may be removably connected to the hinge assembly 144, thus rotatably connecting the organizer tray 200 thereto. For example, protrusions 222 provided on the arms 220 may be inserted in depressions 184 to rotatably connect the organizer tray 200 to the hinge assembly 144.
As discussed, each of the plurality of organizer trays 200 may be rotatable between a first position and a second position. Further, each organizer tray 200 may advantageously be releasably securable in the second position, thus facilitating efficient loading of cables 42 and transmission elements thereof, splicing, etc., into other organizer trays 200 and the assembly 30 generally. The hinge assembly 144 which rotatable connects the organizer tray 200 to the bracket assembly 140 may releasably secure the organizer tray 200 in the second position.
For example, in exemplary embodiments as illustrated in
Further, in exemplary embodiments, the organizer tray 200 may be released from being secured in the second position to move from the second position to the first position. For example, movement of the release tab 182 may cause movement of the positioning tab(s) 180 out of contact with the organizer tray 200 (such as the contact tab(s) 224) thereof such that the organizer tray 200 can move from the second position to the first position. In exemplary embodiments, a user may apply force to the release tab 182 to cause such movement. For example, such force may pivot the release tab 182 and, due to a material connection between the release tab 182 and positioning tab(s) 180, also cause pivoting of the positioning tab(s) 180.

Each splice module 250 may, for example, include a base 252 and a plurality of legs 254 extending from the base 252, such as below the base 252 as shown. The legs 254 may further extend from and at least partially define a periphery of the base 252, and may further be disposed at corners of the base 252. To removably connect a splice module 250 to an organizer tray 200 at a module mounting location 240, each leg 254 may be inserted into one of the leg slots 242 of a module mounting location 240. Further, a splice module 250 may include one or more cantilevered arms 256 extending from the base 252, such as below the base 252 as shown. Each cantilevered arm 256 may include a tab 258 at a distal end thereof. To removably connect a splice module 250 to an organizer tray 200 at a module mounting location 240, the cantilevered arm 256, such as the tab 258 thereof, may be inserted in one of a plurality of positioning slots 244 of a module mounting location 240.
In exemplary embodiments, a splice module 250 may be removably connectable to an organizer tray 200, such as at a module mounting location 240, in multiple different orientations. For example, the plurality of positioning slots 244 may be oriented such that the cantilevered arm 256, such as the tab 258 thereof, may be inserted in a different one of a plurality of positioning slots 244 depending on the orientation of the splice module 250.
Splice modules 250 in accordance with the present disclosure may advantageously be dual material components. For example, splice modules 250 may further include one or more overmolded portions 260 which are disposed on portions of the base 252, such as on a lower surface and sidewalls thereof. The overmolded portions 260 advantageously provide improved structural integrity, rigidity, and protection. The base 252, as well as the legs 254 and cantilevered arms 256 thereof, may for example, be formed from a hard plastic such as polycarbonate or nylon. The overmolded portions 260 may be formed from suitable elastomers, such as vulcanized elastomers.
Splice modules 250 in accordance with the present disclosure may further include a plurality of partitions 262, each of which may extend from the base 252. The partitions 262 may be generally parallel to each other, and neighboring partitions 262 may define channels 264 therebetween. Each channel 264 may define and extend along a longitudinal channel axis 265, as shown. Further, one or more arms 266 may extend from one or more of the neighboring partitions 262 into one or more of the channels 264 defined by such neighboring partitions 262. Such arms 266 may extend into the channels 264 at an angle to the longitudinal channel axis 265, as shown. For example, a first partition 262′ of neighboring partitions 262 may include one or more arms 266 extending into a channel 264 defined by the neighboring partitions 262, and a second partition 262″ of neighboring partitions 262 may include one or more arms 266 extending into the channel 264 defined by the neighboring partitions 262. Further, in exemplary embodiments as shown, the one or more arms 266 extending into a channel 264 from a first partition 262′ may extend in a direction opposite the direction of the one or more arms 266 extending into the channel 264 from a second partition 262″.
In exemplary embodiments, partitions 262 and arms 266 of splice modules 250 may be formed from suitable elastomers, such as vulcanized elastomers.
Splice modules 250 in accordance with the present disclosure, and in particular the configuration of the partitions 262 and arms 266, are particularly advantageous due to their versatility and flexibility in accommodating various components. For example, a channel 264 of a splice module 250 may be capable of holding triple-stacked single spliced transmission elements, double-stacked ribbon spliced transmission elements, mechanical splices, splitter modules from 1:2 to 1:32, PLCs, etc.
Organizer trays 200 may further include one or more retainer tabs 270, each of which may extend from a wall, such wall 206, 208, or 210, into the interior 214. Such retainer tabs 270 may generally assist in routing and retaining cables 42 and transmission elements in the interior 214 during assembly, splicing, etc., thereof.
