Description

OPTICAL TERMINATION AND JUNCTION BOX FIELD OF INVENTION

[001] The present invention relates to an optical cable termination and branching (splicing) box, to be applied to aerial fiber optic networks called FTTH (fiber to the home) to protect an optical splice (splitter) between an optical fiber of a multi-fiber distribution cable received in the box and multiple optical termination cables (drop cables), and / or optical fusion splices between any of the optical fibers of said distribution cable and the optical fibers of a respective optical branch cable (multi-fiber continuation optical cable) or the optical fiber of a respective optical termination cable (drop cable). BACKGROUND OF THE INVENTION

[002] Fiber optic networks require the provision of splice points and user activation terminal points, which are protected by termination and distribution boxes generally installed externally and aerially and fixed to a lead wire, on a pole, on the facade of a building or in a junction box or buried box.

[003] At a splice point, for example, one or more fibers of a distribution cable received at a termination / distribution box are spliced ​​by fusion: to the corresponding fibers of a drop cable coming out of that box to reach a new splice point or a user activation terminal point; or to the optical fiber of a respective optical termination cable (drop cable).

[004] However, at a user activation point, any of the fibers of the optical drop cable, which arrives at an aerial termination box, may pass through a splitter to provide termination cables directed to end users of the network. The fibers of the optical drop cable, which arrive at a termination box but are not connected to a respective termination cable (drop cable), may pass through the box, unchanged or spliced ​​to a new cable segment, to continue to a new splice or user activation point, as explained above.

[005] These termination boxes must be constructed to receive at least one multi-fiber distribution cable and to allow the exit of one or more branch cables and even a plurality of compact termination (drop) cables, which requires internal space for fusion splices in the splitter and for branch cables.

[006] A deficiency of known junction and termination boxes is related to the sealing solutions employed, which offer a high degree of watertightness along with their complex construction and consequent production costs. In some solutions, simplified construction leads to lower production costs but also to deficiencies in the watertightness of the sealing rings (eyelets) at the cable entries and exits, allowing moisture and insects to enter the box. In other solutions, increased watertightness is achieved with high construction complexity and undesirable high production costs.

[007] Examples of termination boxes of the type described herein can be found in documents US 6,226,434, and US 9,310,579.

[008] Due to the aforementioned drawbacks, the applicant has proposed in his patent application BR 10 2019 014363-0 a termination and branch box for aerial optical access networks, which features a simple, versatile construction and substantially lower costs than similar boxes, with a reduced number of sealing elements to obtain the desired degree of watertightness and which can be installed horizontally or vertically on a support cable or the wall of a building or even vertically, directly against a pole, also guaranteeing easy and safe handling of the fiber splicing elements by the respective installation team, without interference with the connection elements of the termination cable to be handled by another installation team, regardless of the installation position of the box.

[009] Despite the advantageous aspects of the box subject to patent application BR 10 2019 014363-0, its design does not provide a sufficiently high level of watertightness to guarantee, for example, watertightness with the box submerged in 1.0 m of water column for 7 days (IP68 sealing system).

[010] Another aspect of the aforementioned box stems from the fact that all the fiber optic cables entering and exiting the box are routed through an elastomeric sealing plate, housed in a cutout on one side of the box's base. Therefore, if it becomes necessary to change the original arrangement of the multi-fiber cables entering and exiting the box, or to perform maintenance on any of the cables already installed through the sealing plate, it is necessary to remove the sealing plate or even disassemble the multi-fiber cables, which tends to compromise the box's airtightness.

[011] Specific and similar drawbacks to those mentioned above can be seen in the termination box that is the subject of patent application BR 10 2015 023980-7 of the same applicant. In this prior construction, a side wall of the base is provided with an opening in which a panel is non-permanently mounted with openings for the passage of a distribution, extension, or termination cable, and connection openings in which the respective i Qccnn / zznz / E / YiAi connectors are mounted so that each receives, at an external end of the box, a movable connector of a termination cable.

[012] In these other previous boxes from the same applicant, all cables entering and exiting the box are routed through the removable panel, which houses the sealing elements in the openings for the multifiber cables and the fixed connectors for connecting the terminal cables. Thus, to change the original arrangement of the multifiber cables entering and / or leaving the box, or to perform maintenance on any of the cables already assembled through the sealing elements (plates), it is necessary to remove the panel and move the multifiber cables and fiber sections inside the box. This tends to cause deficiencies in the sealing not only between the removable panel and the base wall, but also between the sealing plates and the multifiber cables.

[013] In addition to the aspects mentioned above and more directly related to the box sealing problems, it can be said that known solutions do not provide a box with a high degree of airtightness and, even so, a high degree of protection for the fiber optic splitters that connect the fibers from the optical cables received in the box to the fiber optic splitters connected to the output adapters. In these known solutions, the components that hold the fiber splitters can be moved by the various teams that access these boxes during installation and when changing user connections. BRIEF DESCRIPTION OF THE INVENTION

[014] Considering the preceding statement, the present invention aims to provide a termination and branch box for optical access networks, for aerial and / or underground installation, in a horizontal or vertical position on the support cable or on the wall of a building or even in a vertical position, directly against a pole, which has a simple, versatile, easy-to-install construction, with a high degree of watertightness, which allows access to the output adapters, for the connection of the user terminal cables, without the need to open the box and also guaranteeing easy and safe handling of the fiber splicing elements by the respective installation team, without interference on the fiber splitting elements and the connection of termination cables that must be handled by another installation team, regardless of the installation position of the box.

[015] The junction and termination box in question is of a type comprising: a base having a rear wall and peripheral walls defining a front edge; and a lid hinged to the base, having a top wall and peripheral walls defining a rear edge that features a sealing gasket. i Qccnn / zznz / E / YiAi

[016] According to a first aspect of the invention, at least one peripheral wall of the base is provided with side openings flanked, each, by two inclined cutouts and closed, each, by a sealing plate, for the hermetic passage of at least one multi-fiber optical cable and having a first recessed front edge portion and a second front edge portion level with the front edge and incorporating two side tabs, previously coplanar to the first front edge portion and subsequently defining each, an inclined surface to be supported on a respective inclined cutout of the front edge.Each sealing plate is pressed against the side opening by means of a shoe supported on the first portion of the plate's front edge and fixed on the front edge of the base, while a sealing gasket rests and is compressed on the second portion of the plate's front edge and on its two side tabs when the lid is closed against the base.

[017] According to another aspect of the invention, the box comprises a splitter housing tray having a front face, fixed against the upper wall of the lid and having splitter and / or fiber housing means, and a rear face that is covered by a plate fixed inside the lid, each splitter and / or fiber housing means being able to connect, on one side, to a length of fiber derived from an optical cable that is received at the base and, on the other side, to the split fiber lengths, held on the side of the front face and connected to the output adapters passing through at least one of the two opposite peripheral walls of the lid, not hinged to the base, while the output adapters are externally connected to the respective connectors of a terminal cable external to the box.

[018] The above-summarized construction is simple and versatile, and can be installed horizontally or vertically, also guaranteeing easy and safe independent handling of the fiber splicing elements by different installation teams and ensuring a high degree of watertightness to the box when the lid is closed.

[031] As illustrated in the preceding drawings, the optical termination and branch box in question comprises a base 10 and a cover 20 hinged to the base 10, both made of a non-electrically conductive material, with the base 10 incorporating, in one piece, a rear wall 11 and peripheral walls 12 that define a front edge 12a. The cover 20 has a top wall 21 and peripheral walls 22 that define a rear edge 22a that carries a sealing gasket 24, generally made of elastomer.

[032] At least one peripheral wall 12 of the base 10, not hinged to the cover 20, is provided, starting from its front edge 12a, with at least two U-shaped lateral openings 13, each closed by an elastomer sealing plate 30, for the hermetic passage of at least one multi-fiber CO2 optical cable. The CO2 optical cable may be defined by a multi-fiber distribution cable or by one or more multi-fiber branch cables of different diameters.

[033] Each sealing plate 30 has a first front edge portion 31a, recessed in relation to the front edge 12a of the base 10, and a second front edge portion 31b, level with the front edge 12a, each sealing plate 30 being pressed against the respective side opening 13 by means of a shoe 50, for example made of plastic, supported on the first front edge portion 31a of the plate 30 and fixed, by fastening means 55, for example, in the form of screws, on the front edge 12a of the base 10.

[034] A sealing gasket 24 rests and is compressed on the second portion of the front edge 31b of the plate 30 and on the front edge 12a of the base 10 when the lid 20 is closed against the base 10. The rear edge 22a of the lid 20 can be shaped like a channel in which a sealing gasket 24 is partially disposed and retained, as illustrated in the drawings.

[035] In the illustrated construction, each side opening 13 is flanked by two inclined cutouts 13a, while the second portion of the front edge 31b of each plate 30 incorporates two opposing side tabs 31c that project outwards from the perimeter of the sealing plate 30, previously coplanar to the first portion of the front edge 31a and subsequently defining each an inclined surface 31d to be supported against a respective inclined cutout 13a of the front edge 12a, the sealing joint 24 being supported and compressed against the two side tabs 31c of each sealing plate 30 when the lid 20 is closed against the base 10.

[036] The side tabs 31c on the second portion of the front edge 31b of each sealing plate 30 have their inclined surface 31d supported on a respective inclined cutout 13a of the front edge 12a of the base 10 and compressed against the said inclined cutout 13a, by the action of the shoe 50 and also by the seating of the gasket 24, obtaining a high degree of sealing in the mounting region of the sealing plates 30 and in the support region between the base 10 and the cap 20.

[037] Preferably and as illustrated, each shoe 50 incorporates the opposite and coplanar terminal portions 51, which project beyond the width of each side opening 13 and which are each provided with a through hole 51a, the front edge 12a of the base 10 being provided with a recessed step 13b on each side of a side opening 13, adjacent to an inclined cutout 13a and provided with a threaded hole 13c.

[038] On each recessed step 13b rests a terminal portion 51 of a respective shoe 50, while the through hole 51a of each terminal portion 51 is pierced by an adjustment means 55, in the form of a screw, which is inserted and fixed in the threaded hole 13c of the recessed step 13b.

[039] Continuing with the illustrated construction, the angled cutouts 13a are positioned radially internal to the adjacent cutout steps 13b on the front edge 12a of the respective peripheral wall 12 of the base 10, so that the matching side tabs 31c of the second front edge portion 31b of each sealing plate 30 are aligned with a respective extension of the sealing joint 24.

[040] For a secure radial lock of each sealing plate 30 inside a respective side opening 13, the sum of the width of each angled cutout 13a and the width of the adjacent recessed step 13b must be less than the width of the peripheral wall 12 of the base 10 in the region of each side opening 13.

[041] To ensure that each sealing plate 30 completely seals the cross-section, not occupied by a CO optical cable, of each respective side opening 13 in which it is fitted, the plates are provided with transverse holes 33, 34, which have one or more diameters and one end originally closed by the respective breakable side wall portion 35. It is sufficient for the said breakable side wall portion 35 to be easily removed, to allow the passage of a CO multifiber optical cable through the respective transverse hole 33, 34, to enter or exit the box.

[042] According to a second aspect of the invention, the box in question comprises a splitter housing tray 60 having a front face 61, fixed against the upper wall 21 of the lid 20 and having splitter and / or MSF fiber housing means, and a rear face 62 that is covered by a PS splitter protector plate, fixed inside the lid 20 and protecting the splitter and / or MSF fiber housing means (fig. 6).

[043] Each MSF splitter and / or fiber housing medium can be connected, on one side, to a section of EF1 fiber derived from a CO optical cable that is received at the base 10 and, on the other side, to the split EF2 fiber sections, on the front side 61 and connected to the AS output adapters passing through at least one of two opposite peripheral walls 22 of the cover 20, not hinged to the base 10, the AS output adapters being externally connected to respective C connectors of an external CT terminal cable to the box. i Qccnn / zznz / E / γΐΛΐ

[044] In addition to any of the aspects of the invention, defined by the assembly of the sealing plates 30 and by the assembly of the splitting tray 60 with optical splitting protection, the box in question comprises, internally, at least one fusion tray 40, hinged to the base 10 and incorporating FF fiber fusion means and AF fiber length housing means. The at least one fusion tray 40 has a front face 41 facing the lid 20 and a rear face 42 that carries FF fiber fusion means and AF fiber length housing means. The at least one fusion tray 40 can be moved between a first position supported on the base 10 and a second position in which it exposes the FF fiber length fusion means EF1 to the operator.

[045] The example construction is provided with at least two overlapping fusion trays 40, the rearmost being hinged to the base 10 and the front ones hinged to the one immediately behind. To maintain stable positioning of the fusion trays 40 inside the box, the base 10 incorporates internally a locking tab 19, elastically deformable from an operating position, under which it locks the rear fusion tray 40 in its first position supported on the base 10, and a non-operating position, under which it releases the angular displacement of the fusion tray 40 from the first position to the second position.

[046] The base 10 incorporates, in the region of its peripheral wall 12 of the lid 20 articulation, a pair of coupling means 16 where a corresponding pair of articulation fins 46 incorporated into an edge of the tray 40, adjacent to the articulation axis of the lid 20, are detachably and elastically deformed.

[047] The coupling means 16 facilitate work on the rear face 42 of the fusion tray 40 when the box is installed in a vertical position. This allows the operator / installer to expose the fusion trays 40 from the base 10, enabling work on their rear face 42 from a work platform mounted high, next to a support, a building wall, or even a pole. This feature is particularly useful when the box is mounted horizontally.

[048] With the proposed construction, an installation team will be able to perform fusion splicing of the optical fiber using the back face 42 of one or more fusion trays 40, which can be individually and jointly brought to their second position under which they define a kind of horizontal bench, when the box is mounted on a support or in a building, with the hinge of the cover in a horizontal position.

[049] When the box is mounted with the hinge axis of the lid in a vertical position, the rear face 42 of the fusion trays 40 remain in a vertical plane when the tray is moved to its second position illustrated in Figure 3. In such a case, the splicing equipment or optical splitters can simply move the tray 40 to its second position and work on the rear face 42, without risk of causing damage to the CO cable connections and the EF2 fiber lengths.

[050] As illustrated, the rear wall 11 of the base 10 is usually arranged in a vertical mounting plane to remain mounted on a stay cable (not illustrated) by means of suspension hooks 18, attached detachably to the base 10 and which can take different forms, such as the one illustrated as an example.

[051] However, the suspension hooks 18 can be omitted when the outer face of the back wall 11 of the base 10 is fixed directly to a building wall, with the hinge axis vertical or horizontal, by means of, for example, screws (not shown) passing through the side tabs 17 incorporated laterally and externally into the base 10, or even against a post with the hinge axis of the cover 20 arranged vertically. In vertical mounting of the box, the base 10 may be provided with the sealing plates 30 on its lower side face or both sides, but the CO multifiber optical cables will pass through the lower face.

[052] When mounting the box on a post, an external concave cradle 70 is provided and fixed with the ability to be detached to the rear wall 11, of the base 10, by screws 71, arranged in watertight housings provided in said rear wall 11, or by other detachable means of fixing that are suitable, the concave cradle 70 being provided with pairs of opposing side openings 72, for the passage of tapes (not illustrated) in order to fix the box to a post.

[053] Particularly when mounting the box with the articulation axis of the lid 20 horizontally, the trays 40 can be stabilized in their second position by means of their partial support against a region of the peripheral wall 22 of the lid 20, adjacent to its articulation to the base 10, the lid 20 being in an open position coplanar to the base 10 and hanging from the latter.

[054] In the proposed embodiment, the cover 20 is locked to the base 10 by means of multiple T-locks mounted on a peripheral wall 12 of the base 10, opposite the hinge of the cover 20 to the base 10, which can be moved between an open and a closed position, in which it locks the opposite peripheral walls 12 of the base 10 and the cover 20 together. It is understood that the T-locks can also be hinged to a peripheral wall 22 of the cover 20 to act against the base 10 when the optical termination box is closed. In addition to the T-locks, the cover 20 can also be more firmly fixed to the base 10, in the closed condition, by means of a pair of screws 90 passing through the respective lateral regions of the cover 10 and screwed into holes 91 provided in the front edge 12a of the base 10.

[055] Although only one configuration of the optical termination and derivation box of the invention has been illustrated, it should be understood that changes in the shape and arrangement of the components can be introduced, without departing from the constructive concept defined in the claims accompanying this specification.
