Definitions

  • the present disclosure relates generally to telecommunications equipment. More specifically, the present disclosure relates to telecommunications enclosures.
  • Optical splice closures (which are sometimes referred to as splice cases, splice enclosures or splice terminals) generally include a housing which provides a closed space for containing splices between optical fibers. Such closures normally also contain excess lengths of the spliced optical fibers. These excess lengths of the optical fibers are normally used to carry out the fiber splicing operation, which is generally performed using splicing equipment next to the closure. Excess fiber may also be used to facilitate organization of fiber splices in the closure.
  • the optical fiber splice closures normally include one or more trays which hold and manage the splices in an organized manner.
  • the excess optical fibers associated with the organized splices can be stored in the closure in such a way that their bend radii do not fall below minimum bend radius requirements of the fibers.
  • Example closures that are installable in the field and are adapted for protecting fiber optic splices are disclosed by U.S. Patent Nos. 8,213,760; 8,718,434; and 7,751,675. Further closures are disclosed by Patent Cooperation Treaty International Publications WO2016/205340; WO2015/150204; WO2017/046190 and WO2017/046185.

  • the pivot mount 368 can be adjusted in height relative to the component 343 to adjust the position of the stack 340 relative to the component 343.
  • the location of the pivot axis P defined by the pivot mount is adjustable relative to the component 343.
  • the pivot mount 368 include receivers 305 (see Figure 21) for attaching the pivot mount 368 to a selected one of the attachment locations 366a-366c.
  • attachment locations 366a-366c can each include a set of pivot attachments 67 (see Figure 23) that are pivotally received within the receivers 305.
  • the pivot mount 368 can include a mechanical interface such as a snap-fit interface 307 (see Figure 21) that fits within a receiving interface 309 (see Figure 22) defined by the component 343.
  • the pivot mount 368 has only one mounting position relative to the receiving interface 309.
  • the receiving interface 309 can include multiple snap-fit locations (e.g., stops, catches) allowing the pivot mount 368 to be mounted at different vertical positions relative to the component 343.
  • the tray stack 340 can be positioned at different mounting locations to enhance space usage within the enclosure.
  • the mounting locations can be used to progressively occupy portions of the pass-through fiber storage location as fibers stored at the pass-through fiber storage location are used.
  • Figures 25-27 show the pivot mount 368 attached at each of the different attachment locations 366a-366c to provide different fiber storage volumes the tray stack.
  • Figure 28 shows the tray configuration 300 with additional trays mounted at the top side of the tray stack.
