  • Enclosure 16 may include telecommunications equipment, such as splices, splitters, terminations, and wave division multiplexers.
  • Duct 10 includes tubes 14 in the interior of duct 10. Tubes 14 are used to receive fibers, such as air blown fibers where air is used to install the fibers within the tubes 14.
  • Enclosure 16 includes a port 18 through which tubes 14 enter. Port 18 can be initially closed with a cap 20, or other sealing device. Port 18 includes a tubular sleeve 22, including a top edge 24. Sealing device 100 receives poured resin for sealing around tubes 14 within sealing device 100 to thereby seal enclosure 16 from weather or other intrusive elements, such as dust, insects, or rodents.
  • Enclosure 16 can be used with blown fiber technology or one or more cables or fibers of cables extended to the enclosures such as in fiber to the home or other premises. In the case of blown fibers, duct 10 contains the blown fiber tubes 14 connected to port 20 with sealing device 100.
  • Duct 10 is flexible and of a conventional design, and includes corrugations 12. Sealing device 100 connects duct 10 to enclosure 16. In the preferred arrangement, sealing device 100 snap mounts to port 18 during installation, and is prevented from removal, after installation as will be discussed below.

L-shaped locking slots 120 receive side arms 210, 212 of lower tube holder 30 first with axially sliding motion, and ramped surfaces 220 rotate into slots 120 past detents 122 to lock housing 40 to lower tube holder 30 with relative rotation of the two parts. Once locked, tabs 110 are engaged with corrugations 12 of duct 10, tabs 110 cannot flex outward due to outer ring 214 of lower tube holder 30.
  • Housing 40 includes outer tabs 134 for gripping. Seals 140, 142 seal housing in port 18. Vertical slots 148 connect to locking slots 120 to allow housing 40 to be slid over lower tube holder 30 and second end 106 into ring 214. Vertical slots 148 receive side arms 210, 212 during assembly.
  • Notches 224 in ring 214 align with tabs 110 to allow end 106 of housing 40 to slide over base 202 of lower tube holder 30 and into ring 214.

  • Upper tube holder 50 is quarter shaped, in that four upper tube holders 50 together form a 360 degree (circular) shape for receipt in first end 104 of housing 40 9see Fig. 21).
  • Upper tube holder 50 includes a vent hole 316 and a center passage 320.
  • Side projections 330, 332 cooperate with the respective upper slots 130, 132 of first end 104 of housing 40 to align and locate the upper tube holders 50 in the proper locations.
  • Center projections 324 form a general ring shape around center passage 320. It is preferred that upper tube holder 50 be pie-shaped, for ease of use. Other shapes, such as one-third, and one-half pie shapes are possible.
  • Resin potting agent
  • One resin that may be used is a two part resin.
  • the poured resin flows downward toward lower tube holder 30 and center post 204.
  • the resin flows around tubes 14 and fills the area between base 302 of upper tube holder 50 and base 202 of lower tube holder 30. Vent holes 316 allow air to escape from the chamber.
  • snaps 42 cannot be moved radially inwardly to release from top edge 24 of tubular sleeve 22.

  • FIG. 31 shows one of the quarter shaped upper tube holders 50 being inserted over three of the tubes. It is noted that an operator may find the side entry of holes 304 and the sequentially placing upper tube holder 50 of a few tubes easier than mounting all of the tubes 14 at the same time to a single upper tube holder with closed holes.
  • FIG. 32 shows the upper tube holder 50 in position over the three tubes and engaged with the housing, ready for the other three upper tube holders 50 to be installed.

Further, sealing device 100 promotes containment of the resin in a discrete area, and filling of the resin from the bottom (lower tube holder 30) upward toward, and possibly around upper tube holder 50. Vent holes 316 promote air removal for improved sealing.
  • FIGS. 36-42 an alternative sealing device 400 is shown.
  • a lower tube holder 430 is received within housing 440 in a similar manner as lower tube holder 30 described above.
  • Lower tube holder 430 is shown with an extension 434 which is broken off from main body 432. Extension 434 is discarded if twelve tubes are utilized. In the situation where seven tubes are used, extension 434 is used as a blocker over portions of holes 438 to cover five tube openings with plugs 436, thereby leaving room for seven tubes to pass through main body 432.
  • Housing 440 includes an upper end 442 with a plurality of snaps 441 for snapping to port 18, in a similar manner as described above. At a lower end 444 of housing 440, tabs 446 are provided for engaging duct 10. A ring 448 slid upwardly prevents outward flexing of tabs 446 once in the mounted position over duct 18.
  • Upper tube holder 450 is constructed in a similar manner as upper tube holder 50 above wherein each segment is a quarter section. Each segment includes tube openings 454, a central passage 456, and a vent hole 458. Upper tube holder 450 defines slots 452 for receipt of tabs 441 when upper tube holder 450 is positioned in upper end 442 of housing 440.
  • Lower tube holder 530 includes two resin blocking tabs 534 on opposite sides to prevent or reduce resin leakage during assembly before curing.

Des languettes (110) sur la deuxième extrémité (106, 444) viennent en prise avec des cannelures (12) sur un conduit (10) monté sur la deuxième extrémité (106, 444) de l'enveloppe (40, 440). L'enveloppe (40, 440) reçoit des tubes (14) tels que des tubes à fibres soufflées destinés à recevoir les fibres pendant les processus d'installation des fibres soufflées. L'enveloppe (40, 440) définit une chambre (28) destinée à recevoir de la résine qui assure se scelle autour des tubes (14). une fois la résine durcie, les cliquets (42, 441) ne peuvent plus être bougés, ce qui empêche le retrait de l'enveloppe (40, 440) du dispositif de télécommunications. Un support de tubes inférieur (30, 430) est prévu pour l'organisation des tubes (14) adjacents à la deuxième extrémité (106, 444) de l'enveloppe (40, 440). Un support de tubes supérieur (50, 350) est prévu pour l'organisation des tubes (14) adjacents à la première extrémité (104, 442) de l'enveloppe (40, 440). Le support de tubes supérieur (50, 350, 450) définit un passage central (320) destiné à recevoir la résine coulée.
