Definitions

  • the present disclosure relates generally to telecommunications cable organizers for fiber optic cables, and more particularly to telecommunications cable organizers including splitters.
  • the splitters are often attached to a panel or a tray via a carrier or adapter.
  • the panel or tray to which the splitter is attached usually includes, among other things, connection points, parking points and routing elements for the fiber optic cable.
  • the splitters divide each input data signal into a plurality of signals sent to a plurality of output ports of the respective splitter.
  • splitters can have varying sizes, including lengths, widths and height. Typical splitters may include1x4 and 1 x16 splitters, with the 1x16 being longer, taller and wider than the 1x4 splitter. Telecommunications closures often are used to house such splitters of different sizes. During use, it is desired that the splitters not slide or move within the closure. Such movement within a closure can be damaging to the splitters, cables and/or the closures. An improved way of securing splitters, and a variety of splitter sizes, within a closure is desired.
  • One aspect of the present disclosure relates to a housing to receive at least two different sizes of telecommunications fiber optic cable splitters including a body with two opposing ends, a bottom surface, a top surface, a first side surface and an opposing a second side surface.
  • the housing includes a pair of bumpers to apply resilient force to the fiber optic cable splitter first side surface. The bumpers are spaced apart.
  • the housing further includes at least one resilient latch to engage and/or be positioned adjacent the second side surface and be positioned over the top surface of the fiber optic cable splitter.
  • a still further aspect of the present disclosure relates to a housing to receive a telecommunications fiber optic cable splitter.
  • the splitter includes a body with two opposing ends, a bottom surface, a top surface, a first side surface and an opposing a second side surface.
  • the housing includes a first sidewall and a pair of bumpers to apply resilient force to the fiber optic cable splitter first side surface. The bumpers are spaced apart along the first sidewall.
  • the housing also includes a second sidewall and at least one resilient latch to engage the second side surface and grab the top surface of the fiber optic cable splitter. The at least one resilient latch extends through the second sidewall.

  • FIGS. 1 -1 1 B An example embodiment splitter housing 10 is depicted in FIGS. 1 -1 1 B.
  • the example splitter housing 10 depicts an elongated shape defined by parallel sidewalls 12, 14 that are separated apart by and secured together with a channel floor 38.
  • the sidewalls 12, 14 extend from a fixed edge at the channel floor 38 to a free edge.
  • the splitter housing 10 depicts an open top opposite the channel floor 38.
  • the splitter housing 10 further depicts a first open end 16 and an opposite second open end 18, each positioned at an end of the housing.
  • the splitter housing 10 also depicts a first lip 20 rising from the channel floor 38 at the first open end 16, and a second lip 22 rising from the channel floor 38 at the second open end 18.
  • the depicted channel floor 38 can be defined by the parallel side walls 12, 14 and the end lips 20, 22.
  • the end lips 20, 22 are positioned apart a distance that allows the splitter housing 10 to receive a range of splitter sizes, (see FIGS. 4, 5).
  • the depicted splitter housing 10 can have a pair of cutout apertures 34 extending partially along the first sidewall 12 and partially along the channel floor 38.
  • the cutout apertures 34 are positioned near each end of the splitter housing 10.
  • the depicted cutout apertures 34 do not extend to the free edge of the first sidewall 12, and do not extend entirely across the channel floor 38.
  • a pair of bumpers 36 is depicted to be positioned within the pair of cutout apertures 34. As depicted, the bumpers 36 are secured to the top edge of the cutout apertures 34 along the first sidewall 12, for example with uniform molding. Alternatively, it is contemplated that additional cutout apertures 34 and bumpers 36 can be introduced to receive larger splitters.
  • the buttons 44 contact the sides of the splitter, thus applying an outwardly-directed force that flexes the bumpers 36 into and through the cutout apertures 34.
  • the bumpers 36 apply an equal and opposite force onto the large splitter 50, which helps to maintain the position of the large splitter within the housing 10.
  • the bumpers 36 naturally return to a rest state (see FIG. 1 ).
  • buttons 44 are positioned at a location to receive an end 69 the small splitter 60, and prevent the small splitter from sliding in either direction within the housing 10.
  • Splitter 60 is positioned against one of lips 20 or 22.
  • Splitter 60 can be mounted in splitter housing 10 at the opposite end, and the other splitter end 69 is engaged by the button 44 of the other bumper 36.
  • the depicted housing 10 can have a pair of cutouts 30 extending from the free edge of the second sidewall 14 and downwardly toward the channel floor 38.
  • the cutouts 30 can extend to align with the channel floor 38 or terminate at a position along the second sidewall 14 above the channel floor.
  • the pair of cutouts 30 is depicted to be positioned a narrower distance apart than the cutaway apertures 34 (see FIGS. 6, 7), however, the cutouts 30 can also be positioned wider apart than the cutaway apertures 38 (not shown).
  • a pair of clips (also called latches) 32 are depicted to be fixed to and extend within the cutouts 30.
  • the depicted clips 32 have a base or spine 42 that is fixed to and extends from the bottom edge of each cutout 30 toward the free edge of the second sidewall 14.
  • the depicted pair of clips 32 can have ledges (or grips) 46 extending from the free end of the bases 42.
  • the depicted ledges 46 have a free end that extends to a position over the channel floor 38 of the housing 10.
  • the ledges 46 can have angled chamfers at the inward-facing edge and the outward-facing edge. At rest, as particularly depicted in FIG.
  • the clips 32 are angled slightly inward, so that the base 42 outer surface is not in planar alignment with the outer surface of the second sidewall 14.
  • the base 42 can resiliently flex into and out of the cutouts 30 toward and away from the channel of the splitter housing 10.
  • splitters 50, 60 are inserted into the housing 10 between the sidewalls 12, 14.
  • the splitters 50, 60 can be wider than the distance between the inner surface of the first sidewall 12 and the free end of the clip ledge 46 in a rest state.
  • the splitters 50, 60 contact the angled chamfers at the free end of the ledges 46 and force the bases 42 to flex into the cutouts 30.
  • the base 42 flexes back to the rest state and overhangs, but does not have to contact, the top surface of the splitters, as particularly depicted in FIGS. 4-10.
  • This overhanging relationship of the ledges 46 over the splitters 50, 60 prevents the splitters from exiting from within the housing 10.
  • a user applies an outward pressure to the ledges 46 to flex the bases 42 into the cutouts 30 and away from overhanging the splitters.
  • More or less latches 32 and more or less bumpers 36 can be provided as desired.
  • a pair of fasteners 48 extend from the bottom surface of the housing channel floor 38.
  • the depicted pair of fasteners 48 can have a dovetail shape that widens away from the housing 10.
  • FIG. 12 depicts a plurality of the above-described splitter housings 10 secured in parallel within a commercially-available telecommunications equipment closure 100.
  • the closure 100 includes a plurality of tiered apertures 106 and a plurality of parallel track receivers 104 positioned along the closure floor 102.
  • Example tiered apertures 106 have wide regions and narrow regions.
  • Track receivers 104 also have wide regions and narrow regions.
  • the described housing 10 secures to the closure 100 by securing the pair of fasteners 48 to a tiered aperture 106 and a parallel track receiver 104.
  • One fastener 48 can insert through the wide region of a tiered aperture 106, and the other fastener 48 can slide into the parallel track receiver 104.
  • the entire housing 10 is then slid in a direction that locks the fasteners into the narrow region of the tiered aperture 106 and further into the track receiver 104.
  • the splitter housing 10, including the sidewalls 12, 14, the bumpers 36, the dovetail fasteners 48 and the clips 32 are formed of unitary construction through, for example, injection molding.
