    [0002] Tensile fiber optic distribution device
    [0003]
    [0004] Field of the Invention
    [0005]
    [0006] The present invention relates to an optical fiber distribution device from a multi-fiber connection cable, mounted inside a building and having a modular construction, to allow initial installation with low investment, for attention of a first user in the aforementioned building, and an easy and rapid gradual expansion of the capacity of connection to additional branch cables for new users of the building, without requiring disassembly, constructive modifications and even without requiring access to the interior of the initial installation of attention of the first user.
    [0007]
    [0008] Background of the invention
    [0009]
    [0010] With the popularization of fiber optic services that reach users' homes (types of network called FTTH- "Fiber to the Home") and the potential of clients that may require such services, the need to reduce time has emerged invested in each user activation, mainly due to the operational difficulties associated with the shortage of skilled labor for the job and the need for appropriate equipment for more complex installations.
    [0011]
    [0012] Due to the factors mentioned above, there is the desire and even the demand for technical solutions for user-client activation, which enable a fast, intuitive and secure installation. These factors make inadequate the use of boxes with very simple internal architecture and prone to generate problems when it is necessary to access several times inside to make the connection of cables of derivation of new subscribers that are activated gradually from the same distribution box optics.
    [0013]
    [0014] Thus, despite being related to a relatively small initial investment based on their constructive simplification, these optical distribution boxes, with simple internal architecture, have the disadvantage of not allowing an easy, fast and safe gradual expansion of the cables bypass that are subsequently connected.
    [0015] To avoid the problem of excessive constructive simplification of junction boxes, FTTH internal network installations are often oversized at the beginning, anticipating the future increase in the number of users of the internal network in a given building. But this strategy generates an initial investment greater than what would be required to meet the needs of a first user only.
    [0016]
    [0017] In the installations of a fiber optic network inside a building, a distribution box is used in which an optical cable containing multiple optical fibers is received, in an amount that allows users of the building in general to attend, although initially it is part or only one user.
    [0018]
    [0019] The distribution box considered here is used to provide the separation of an optical fiber from the optical connection cable, so that this optical fiber is directed towards the residence of a user in the building by means of an optical fiber extension known as FTTH ( "Fiber To The Home").
    [0020]
    [0021] Depending on the fact that in many cases the initial installation of the aforementioned distribution box is directed to the attention of only one user, different construction solutions have been proposed to provide an optical distribution box or device that allows a progressive expansion of the cables branch (user cables) that have been divided from the same fiber separated from the optical connection cable inside the distribution box.
    [0022]
    [0023] Examples of boxes or distribution devices of the type considered herein can be seen in US 2015/0355428 A1 and WO 2015/158121 A1, which describe solutions in which the device consists of one or more boxes or parts, provided with elements that allow the reception of the optical connection cable, its retention and its derivation in an optical fiber to be divided and associated with multiple output adapters arranged so that each one receives a respective connector of a branch cable directed towards a corresponding user in building.
    [0024]
    [0025] In spite of allowing the progressive connection of different users of the building, the previous constructions are initially formed with all the elements capable of meeting the potential of users to be gradually activated at different times from a distribution device in a given building.
    [0026] In this way, known optical distribution devices do not facilitate the activation of a new user without the possibility of disconnections and failures at points that have already been previously activated, as well as the possibility of using branch cables with different sections of the cable and without using tools to anchor them.
    [0027]
    [0028] Summary
    [0029]
    [0030] In view of the aforementioned aspects, the present invention aims to provide an optical fiber distribution device from an optical connection cable inside a building, presenting a construction that allows an initial installation that requires low investment, to serve a first user, and an easy, fast and safe gradual expansion of the distribution capacity of additional branch cables, for new users, without requiring disassembly, constructive modifications and even access to the interior of the initial service installation to the First user

    [0062] Description
    [0063]
    [0064] As illustrated in the drawings, the optical distribution device in question comprises a basic module MB and an expansion module ME, both in electrical non-conductive material, such as in polymer.
    [0065]
    [0066] The basic module MB comprises a basic box 10, of square shape, which has rounded edges and is defined by a bottom wall 11 and by side wall portions 12, one of which is provided with an input 12a for an optical connection cable. , while an opposite side wall portion is provided with an outlet 12b for said optical cable CO.
    [0067]
    [0068] The input 12a and the output 12b of the basic box 10 are associated with respective clamps 13a, 13b, to provide an anchor of the outer layer of the optical cable that is received inside the basic module MB.
    [0069]
    [0070] The basic box 10 also incorporates in its interior, an anchor 14 for low friction type cable, an anchor support 15 for the tensile elements of the optical cable CO, a central reel 16 for winding the fiber optic FO derived from the cable optical inside the basic box 10 (see figure 2), a plurality of winding guides 16a, peripherally associated with the central reel 16, a support 17 for receiving a fiber optic splice protector FO (removal of the optical cable CO ) with an extension of fiber F ("pigtail") to be wound around the central reel 16, its free end, by means of a suitable outlet connector CS, being coupled to an outlet adapter AS that is embedded in a connection opening 12c provided in the side wall portion 12 having the inlet 12a for the optical cable CO.
    [0071]
    [0072] The construction described above for the basic module MB allows it to be provided in an internal installation of a building, to serve only a first user. For this, it is sufficient that an end connector (not illustrated) of a branch cable of said first user is coupled to the output adapter AS of the basic box 10 of the basic module MB.
    [0073]
    [0074] The basic box 10 may still be provided with a rubber ring AB at the outlet 12b and even at its entrance 12a, for the protection of the confronting portions of the optical cable CO.
    [0075]
    [0076] The basic module MB also comprises a front cover 20, to be seated, with the same square shape of rounded edges, on a leading edge free of the side wall portions 12. The front cover 20 is fixed to the basic box 10 by a screw (not illustrated), inserted in a central hole 21 of the front cover 20, the central hole 21 being provided with an elongated recess 21a intended to receive the head of the screw whose body is retained inside a tubular projection 18 of the bottom wall 11 of the basic box 10.
    [0077]
    [0078] The bottom wall 11 is provided with holes 11a, 11b to allow the passage of screws (not shown) for fixing the basic module MB to any supporting surface in a building.
    [0079]
    [0080] The fact that the basic box 10 and its front cover 20 have a miamsa square shape, allows the front cover 20 to be mounted and fixed in any of four positions angularly offset from one another by 90 degrees, on an anterior edge free of side wall portions 12, allowing said front cover 20 to always remain in the same correct reading position of the inscriptions that are usually applied therein and that are related to the technical characteristics of the basic module MB, even if the basic box 10 has to be mounted in positions rotated by 90 °, 180 ° and 270 ° in relation to the position illustrated in the drawing figures, so that the entrance 12a and the outlet 12b of the basic box 10 are arranged in a same alignment of the optic connection cable CO.
    [0081] The basic box 10 has two side wall portions 12, opposite each other and different from those provided at the inlet 12a and outlet 12b, and each externally incorporates a guide 19, approximately "T" whose function will be described later. .
    [0082]
    [0083] After the basic module MB has been installed and a connection (not illustrated) with a first user has been activated, the expansion of the number of users to be connected, simultaneously or gradually, to the same optical distribution device may be required, which it makes necessary the provision of the expansion module ME which, in the illustrated construction, allows to divide the fiber extension F, which feeds the output adapter AS of the basic module MB, for example, into eight fibers to serve eight different users to be gradually connected to the distribution device.
    [0084]
    [0085] In the illustrated construction, the expansion module ME comprises an additional box 30, opened in its front part and has a bottom wall 31 which in its front part incorporates portions of side wall 32 and, later in part of its extension from a upper edge, incorporates a pair of side flanges 33, parallel to each other and sized and configured to fit externally and in a sliding and adjusted manner, in the side wall portions 12 of the basic box 10, each provided with the aforementioned element of guide 19.
    [0086]
    [0087] Each guide element 19 is embedded in a groove 33a provided internally along part of a respective side flange 33, allowing the engagement between the two boxes to be carried out precisely.
    [0088]
    [0089] Each slot 33a has an elongated and open inlet end towards a longitudinal edge of the respective side flange 33, allowing the expansion module ME to initially seat on the basic module MB, the two guide elements 19 of the latter being embedded in the open ends of grooves 33a. Next, the expansion module ME slides over the basic module MB, causing the two guide pins 19 to slide along the grooves 33a, until a full engagement position is reached between the two boxes 10.30.
    [0090]
    [0091] A lower portion of the additional box 30, devoid of the side flanges 33, has a greater depth, the bottom wall 31 forming a step 34 turned towards an internal region to the side flanges 33 where an EC input connector arranged of mode which is coupled to the output adapter AS of the basic box 10 when the insertion of the additional box 30 onto the basic box 10 is completed, as illustrated in Figures 6 and 8.
    [0092]
    [0093] The coupling system between the two boxes ensures or alignment between the output adapter AS of the basic box 10 and the input connector CE of the additional box 30, causing the connection between the two elements to occur without any risk of a face The front output adapter AS of the basic box 10 interferes with some other part of the additional box 30, before the end of the insertion of one box into the other.
    [0094]
    [0095] The interior of the additional box 30 is sized and configured to receive and accommodate an expansion fiber FE, and has one end coupled to the input connector CE and an opposite end coupled to a splitter device D, in which the expansion fiber FE It is divided into multiple user fibers FU, in the illustrated example eight user fibers FU are provided, each having an end coupled by means of an expansion connector (not shown), to an AEX expansion adapter turned towards the inside the additional box 30, to receive the coupling of a respective plug connector (not shown) of a drop cable (not shown) to perform the activation of a user.
    [0096]
    [0097] One of the aforementioned AEX expansion adapters is used to connect the bypass cable of the first user who was using the direct connection to the AS output adapter of the MB basic module.
    [0098]
    [0099] The interior of the additional box 30 is conveniently provided with elements, already known in the art, to accommodate the extensions of optical expansion fibers FE and user FU.
    [0100]
    [0101] As best illustrated in Figure 9, the additional box 30 is provided with a through-tube tubular housing 35, internally threaded at least part of its extension, inside which a guide element 36 is housed which, when rotated in the direction time, presses a tongue 37, cut in the bottom wall 31 of the additional box 30, forcing it to deform elastically outwards, so that an external projection 37a incorporated therein, penetrates the elongated recess 21a of the central hole 21 of the front cover 20 of the basic box 10, promoting the blocking of the additional box 30 in its fully embedded position on the basic box 10, and in which the CE input connector of the additional box 30 is coupled to the output adapter AS of the basic box 10.
    [0102] The additional box 30 é in its front part is closed by a tilting cover 40 which is articulated in the part in an upper side wall portion 32 of the additional box 30, to be slidable between a closed position, seated against the additional box 30 , and an open and elevated position, which exposes the AEX expansion adapters and allows an operator to lift the tilting lid 40, keeping it in an open position, in order to have access to one or more of the AEX expansion adapters and that Activate mode, through the ME expansion module, not only the first user who was previously connected to the basic MB module, but also one or more additional users, without the need to make any access or modification in the basic MB module that remains closed in its front part by its front cover 20 or inside the rear area of the additional box 30 in which the expansion fiber FE and the fib are housed FU user level, provided by the D splitter and connected to the AEX expansion adapters.
    [0103]
    [0104] For the convenience of the operator and as illustrated in Figure 1, the tilting cover 40 incorporates an end flange 43, turned towards the additional box 30 and incorporating an external tooth 43a that is embedded, by slight elastic deformation of the end flange 43, inside a recess 38a provided in an opposite wall portion 38 of the additional box 30. Thus, the tilting cover 40 remains stabilized in its fully open position, allowing the operator to perform, simply and quickly, the gradual activation of different users, without needing any special tools for the user activation operation. To this end, the AEX expansion adapters are each mounted on a respective support S that is pivoted on the additional box 30, to be able to be selectively and manually slid between a retracted position, in which it remains parallel to the bottom wall. 31 of the additional box 30, and a mounting position, in which it is pivoted forward, in order to facilitate the coupling of a respective DC cable connector of a user's CD drop cable, as illustrated in the figure 3.
    [0105]
    [0106] The tilting lid 40 always remains attached to the additional box 30 in any operational position, this being an important operational aspect due to the fact that this type of distribution device is often installed in building distribution cabinets, called "shaft", where there is a risk that any loose parts in the box will be lost during the operations performed on the device. The rocker cover 40 is also provided with a projection 48 which, in the closed position, cooperates with the locking element 39 which is incorporated in the front part of the additional box 30, allowing the use of a security seal or padlock, for prevent unauthorized access to the interior of the distribution device.
    [0107] The additional box 30 of the expansion module ME can be provided with a fixing system of an anchor module 50 for the different branch cables CD, said anchor module 50 being able to fit in two grooves 39a, in T format, provided at the bottom of the additional box 30. The fact that the anchor module 50 is removable, allows its easy replacement by anchorage modules designed in accordance with the type of branch cable to be anchored.
    [0108]
    [0109] Although only one configuration of the expandable optical expansion device in question has been illustrated here, it will be understood that it is possible to make variations in shape and arrangement of the components, without departing from the constructive concept defined in the claims that accompany the present specification.
