    System and method for fixing fiber optic tubes in splice trays. Cross reference with related requests
    This request claims priority over the provisional US request. . 61 / 822.040, 5 filed on May 10, 2013, this application is hereby incorporated by reference in its entirety. Background
    Fiber optic distribution systems may include equipment such as trays that are mounted in telecommunications enclosures, where the trays can accommodate 10 fiber terminations in the form of splices or splitters. Such trays can be provided as pivoting trays that can be tilted for access to the trays. There are several concerns with such fiber optic distribution systems, including density, ease of use and cable management. Another concern when using equipment such as enclosures with trays is the effect of temperature variation on 15 fiber optic cables that approach and move away from the enclosures. Outdoor exposure can negatively impact fiber optic cables that are fixed with respect to such enclosures. For example, environmental conditions such as extreme heat and cold can lengthen and shrink the tubes that carry the optical fibers. Elongation can also occur in aerial applications due to ice load, wind load,
    20 etc. The lengthening of the tubes that carry the fiber optic cables can cause the buckling of the tubes at the fixation points and thus affect the optical fibers therein.
    Improvements in tube fixing devices and methods are desired. Compendium
    25 Some aspects of the description are directed to a fiber optic tube fixing system for a tray, where an articulation structure for the tray forms at least a part of the fixing system for fixing the fiber optic tubes in the tray. tray. According to the system example, at least a part of the fiber optic tube extends at least partially into a C-shaped channel formed by the structure of
    30 tray articulation. The C-shaped channel acts as a clamp to fix the tube against axial pulls but allows the axial extension or contraction of the tube with respect to the tray.

    Reference will now be made in detail to some examples of aspects of the present description which are illustrated in the accompanying drawings. Whenever possible, the same reference numbers will be used in all drawings to refer to the same or similar parts.
    Referring to FIGS. 1-5 in general, a fiber optic tube fixation system 10 for a tray 12 is illustrated. In FIG. 1, a fiber optic distribution system 14 is illustrated that includes a fixed telecommunications installation 16 in the form of an enclosure having a plurality of tilting trays 12 containing fiber optic splices 18. If desired, dividers 19 can also be provided. The trays 12 are pivotally mounted in the fixed installation 16 to allow the trays 12 to be tilted for access to the interiors of the trays 12. The fiber tube fixing system 10 Optical of the present description is used to fix a tube 20 that carries the optical fibers 22 to one of the tilting trays 12. As shown, a feeding tube 20 enters the telecommunications enclosure at an entry point 26 and extends to the splice tray 12. According to the inventive aspects of the present description, the splice tray 12 defines a tube fixing point 28 in an articulation structure 30 of the splice tray 12. Once a tube 20 carrying the optical fibers 22 is fixed in the splice tray 12 at the fixing point 28, the individual fibers 22 extending from the tube 20 can enter the tray It should be noted that the ban You leave 12 can be splice-only trays, divider trays, combinations thereof, or accommodate equipment that has other functions.

    5 FIG. 2 illustrates one of the splice trays 12 of the enclosure of FIG. 1 isolated, wherein the articulation structure 30 of the splice tray 12 defines the tube fixing point 28 for the tray 12, and FIGS. 3-5 illustrate perspective views of the articulation structure 30 that forms a part of the fiber optic tube fixation system 10 of the present description.
    10 As shown in FIGS. 2-5, in the example shown of splice tray 12, each tray 12 includes an articulation structure 30 on the right side 34 and on the left side 36 of the tray 12. Any of the articulation structure 30 can be used to fix the tubes 20 carrying the optical fibers 22, depending on which side of the tray 12 is used for the entry of the fibers 22.
    15 Each articulation structure 30 defines a transverse cross-section 38 with a generally C-shape having a rounded exterior 40, a rounded interior 42 and an inlet part 44 to go from the exterior 40 to the interior 42. The exterior 40 of the structure of articulation 30 has a size and is configured to fit by elastic jump in an articulation gap 46 defined by articulation walls 48 in the fixed installation of
    20 telecommunications 16. The recess 46 defines a retention part 50 and a pivot coupling part 52. The retention part 50 defines a transverse transverse dimension that is generally smaller than the transverse transverse exterior dimension 40 of the articulation structure 30, such that the articulation structure 30 is flexibly snapped into the gap 46. The cross section with
    25 C-shape 38 of the articulation structure 30 allows the articulation structure 30 to be flecked inside the recess 46. The pivot coupling portion 52 of the recess 46 defines a transverse transverse dimension of similar size to the exterior 40 of the articulation structure 30 to allow pivotal movement of splice tray 12.
    The part of the articulation structure 30 that fits by elastic jump in the hollow of
    30 articulation 46 in the fixed telecommunications installation 16 defines a groove 54 that is flanked at a first end 56 by a first flange 58 and at a second end 60 by a second flange 62. Thus, with the first and second flanges 58, 62 bumping the walls 48 that define the articulation gap 46, the trays of As indicated above, the C-shaped cross-sectional shape of the articulation structure 30 provides flexibility for the articulation structure 30 when the Articulation structure 30 is snapped into the articulation recess 46. The C-shaped configuration of the articulation structure 30 also defines a channel 64 to receive and hold the fiber optic tubes 20. The cross-sectional dimension of the inlet portion 44 of the C-shaped cross-section 38 has a generally smaller size than the transverse cross-sectional dimension of the tube 20 so that the tube 20 is suddenly prevented from leaving the channel 64 through the inlet portion 44. The cross-sectional dimension of the rounded interior 42 of the C-shaped cross-section 38 is also generally smaller than the transverse cross-sectional dimension of the tube 20 to provide a friction fit tight with the tube 20. In this way , if the tube 20 fits by elastic jump in the articulation structure 30 through the inlet part 44 of the C-shaped cross-section 38 or is inserted axially in the channel 64 (from the open ends 66, 68), the tube 20 is attached to the articulation structure
    image5
    30. When at least a part of the tube 20 is inserted or snapped into at least a part of the channel 64 defined by the articulation structure 30, the tube 20 is axially fixed with respect to the articulation structure 30
    Since the articulation structure 30 defines the first and second open end 66, 68 at both ends of the C-shaped channel 64, the articulation structure 30 can accommodate any elongation or compression / contraction of the tubes 20 along of its longitudinal axes, without affecting the optical fibers 22 therein. The tubes 20, although generally axially fixed with respect to the articulation structure 30, can still move within the channels 64 to accommodate the expansion or contraction of the materials depending on the weather.
    Once at least a part of the tube 20 carrying the optical fibers 22 is snapped in or is inserted at least partially through the C-shaped channel 64 and fixed with respect thereto, the fibers Optics 22 may extend out of the tube 20 in the splice trays 12 for additional splices.
    Although in the present description, the telecommunication equipment in which the inventive tube fixing system 10 is used and illustrated are splice trays 12, these types of splice trays 12 are simply some examples of pieces of equipment telecommunications with which the inventive tube fixing system 10 can be used. The tube fixing system 10 of the present description can be used in other equipment that has articulation structures that allow the equipment to pivot, where the tubes 20 carrying optical fibers 22 have to be fixed with respect to

    5 such team.

Since many embodiments of the description can be made without departing from the spirit and scope of the description, the inventive aspects reside in the appended claims below.
