Description

"CAIXA DE TERMINAÇÃO DE REDE ÓPTICA" "OPTICAL NETWORK TERMINATION BOX"
Campo da inovação  Innovation field
[001] A presente inovação, na natureza de modelo de utilidade, refere-se a uma caixa de terminação na forma de uma roseta óptica compacta, de baixo custo, robusta e versátil, para definir um ponto de terminação em um ambiente interno de uma rede de telecomunicação do tipo FTTx, permitindo a conexão entre um cabo "drop" com um cordão óptico de um terminal de rede óptica ou modem, disposto nas dependências de um usuário.  [001] The present innovation, in the nature of a utility model, refers to a termination box in the form of a compact, inexpensive, robust and versatile optical rosette to define a termination point in an internal environment of a telecommunication network of the FTTx type, allowing the connection between a "drop" cable with an optical cord from an optical network terminal or modem, arranged on a user's premises.
Antecedentes da inovação  Background to innovation
[002] A caixa de terminação ou roseta óptica da presente inovação é do tipo usualmente fixado em uma parede ou em outra estrutura de sustentação, no interior de uma dependência de um usuário, para receber um cabo "drop" em cujo extremo é incorporado um respectivo conector a ser acoplado, no interior da caixa de terminação, a um terminal construído para receber o encaixe do conector extremo de um cordão óptico do terminal de rede ou modem do usuário da rede óptica .  [002] The termination box or optical rosette of the present innovation is of the type usually fixed on a wall or other support structure, inside a user's dependency, to receive a "drop" cable at the end of which is incorporated a respective connector to be coupled, inside the termination box, to a terminal built to receive the fitting of the extreme connector of an optical cord of the network terminal or modem of the user of the optical network.
[003] Apesar de serem normalmente utilizadas, as conhecidas caixas de terminação óptica, conhecidas como rosetas ópticas, apresentam uma base, em forma de bandeja, tendo dimensões projetadas para receber e reter, por enrolamento em seu interior, uma extensão de um ou mais cabos "drop" de um determinado padrão dimensional, sendo o extremo de cada cabo "drop" provido de um respectivo conjunto de conector e terminal alojado no interior da base, a qual é anteriormente fechada por uma tampa de dimensões compatíveis com aquelas da base em bandeja. [004] O tipo de construção acima mencionado conduz a caixas de terminação ou rosetas ópticas pouco compactas, de construção relativamente complexa e onerosa, em razão dos elementos internos da base, necessários para acomodação e retenção da ou das extensões de cabo "drop" . [003] Despite being normally used, the known optical termination boxes, known as optical rosettes, have a tray-shaped base, having dimensions designed to receive and retain, by winding inside, an extension of one or more "drop" cables of a given dimensional pattern, the end of each "drop" cable being provided with a respective connector and terminal set housed inside the base, which is previously closed by a cover of dimensions compatible with those of the base in tray. [004] The type of construction mentioned above leads to termination boxes or optical compact rosettes, of relatively complex and expensive construction, due to the internal elements of the base, necessary for accommodation and retention of the drop cable (s).
[005] Além dos inconvenientes acima citados, essas conhecidas rosetas exigem operações mais demoradas e cuidadosas para acomodação e retenção da ou das extensões de cabo "drop" no interior da base-bandeja e exigem um posicionamento especifico na montagem da tampa contra a base, requerendo que a fixação dessa última na parede ou estrutura de suporte seja feita também em uma condição especifica para evitar que a tampa, quando montada, fique de ponta cabeça.  [005] In addition to the aforementioned inconveniences, these known rosettes require more time-consuming and careful operations to accommodate and retain the drop cable extension (s) inside the tray base and require a specific positioning when mounting the lid against the base, requiring that the fixation of the latter on the wall or support structure also be made in a specific condition to prevent the cover, when mounted, from upside down.
[006] Outra deficiência dessas conhecidas rosetas ópticas resulta do fato delas terem sua base em bandeja projetada em função do tipo de cabo "drop" a ter uma extensão acomodada e retida no interior da bandeja, o que limita a versatilidade de aplicação dessas rosetas ópticas a diferentes padrões e bitolas de cabos "drop" . [006] Another deficiency of these well-known optical rosettes results from the fact that they have their tray base designed according to the type of "drop" cable to have an extension accommodated and retained inside the tray, which limits the versatility of application of these optical rosettes different standards and cable gauges "drop".
[007] Um exemplo de caixa de terminação do tipo aqui considerado pode ser encontrado no documento de patente brasileiro PI1107334-9 A2.  [007] An example of a termination box of the type considered here can be found in the Brazilian patent document PI1107334-9 A2.
Sumário da inovação  Summary of innovation
[008] Tendo em vista os aspectos acima discutidos, a presente inovação tem, por objetivo, a provisão de uma caixa de terminação ou roseta óptica de construção simples e compacta, de dimensões relativamente reduzidas, de baixo custo de fabricação, permitindo uma fácil e segura retenção axial de diferentes padrões e bitolas de cabos "drop", para definir um ponto de terminação em um ambiente interno de uma rede de telecomunicação e sua conexão com um cordão óptico de um terminal de rede óptica ou modem, disposto nas dependências de um usuário. [008] In view of the aspects discussed above, the present innovation aims to provide a termination box or optical rosette of simple and compact construction, of relatively small dimensions, of low manufacturing cost, allowing an easy and secure axial retention of different patterns and cable gauges "drop", to define a termination point in an internal environment of a telecommunication network and its connection with an optical cord from an optical network terminal or modem, arranged on a user's premises.
[009] A presente inovação tem ainda o objetivo de prover uma caixa de terminação ou roseta óptica que, além de apresentar as caracteristicas funcionais acima citadas, permita um posicionamento final adequado para a tampa, mesmo no caso de a base ser fixada em sua estrutura de suporte em uma posição invertida.  [009] The present innovation also has the objective of providing a termination box or optical rosette that, in addition to presenting the functional characteristics mentioned above, allows an adequate final positioning for the cover, even if the base is fixed in its structure support in an inverted position.

[015] Figure 5 represents a cross-sectional view of the box, taken along lines V-V in figure 1, illustrating the interaction of the retaining elements between the lid and the base of the rosette.
Descrição da inovação  Description of the innovation
[016] Conforme ilustrado nos desenhos e acima mencionado, a caixa de terminação ou roseta óptica em questão é utilizada para alojar e reter um cabo "drop" (CD) e um terminal de conexão (TC) no qual são engatados um conector extremo (CE) do cabo "drop" (CD) e um plugue extremo (PE) de um cordão óptico do terminal de rede ou modem de um usuário da rede óptica .  [016] As illustrated in the drawings and mentioned above, the termination box or optical rosette in question is used to house and retain a "drop" cable (CD) and a connection terminal (TC) to which an end connector ( CE) of the drop cable (CD) and an end plug (PE) of an optical cord from the network terminal or modem of a user of the optical network.
[017] De acordo com a inovação, a caixa ou roseta óptica compreende uma base 10 em forma de placa retangular alongada, em material não condutor elétrico, por exemplo, um polimero, a ser posteriormente assentada e fixada em uma parede ou qualquer outra estrutura de suporte (não ilustradas) .  [017] According to the innovation, the box or optical rosette comprises a base 10 in the form of an elongated rectangular plate, in non-conductive electrical material, for example, a polymer, to be subsequently seated and fixed on a wall or any other structure support (not shown).
[018] A base 10 tem uma primeira e uma segunda borda extrema 11,12, um par de bordas longitudinais 13, e uma face anterior 10a incorporando, junto à primeira borda extrema 11 e geralmente em peça única, um mordente 20, em forma de canal longitudinal C com paredes laterais 21 incorporando dentes 22 projetantes radialmente para dentro do canal longitudinal e inclinados em direção à segunda borda extrema 12 da base 10. O mordente 20 é dimensionado para receber e reter, axialmente, em seu interior e por meio dos dentes 22, uma respectiva extensão de um cabo "drop" (CD) que pode ser definido por um cabo "micro indoor - low friction", um cabo "drop" compacto "low friction", ou ainda um cabo óptico "drop" circular de 3mm. [018] The base 10 has a first and a second extreme edge 11,12, a pair of longitudinal edges 13, and an anterior face 10a incorporating, next to the first extreme edge 11 and generally in one piece, a jaw 20, in the form longitudinal channel C with side walls 21 incorporating teeth 22 projecting radially into the longitudinal channel and inclined towards the second extreme edge 12 of the base 10. The clamp 20 is dimensioned to receive and retain, axially, inside and through the teeth 22, one respective extension of a "drop" cable (CD) that can be defined by a "micro indoor - low friction" cable, a compact "drop" low friction cable, or a 3mm circular "drop" optical cable.
[019] A construção do mordente 20, provido dos dentes 22 atuando contra a capa externa do cabo "drop" inserido no referido canal longitudinal C, permite que a retenção desses cabos no mordente 20 suporte maiores cargas de tração axiais, por exemplo, da ordem de 100N para os cabos "micro indoor low friction", "drop" compacto "low friction" e cabos "drop" circular de 3mm.  [019] The construction of the clamp 20, provided with the teeth 22 acting against the external cover of the "drop" cable inserted in said longitudinal channel C, allows the retention of these cables in the clamp 20 to support greater axial traction loads, for example, order of 100N for "micro indoor low friction", compact "drop" low "friction" cables and 3mm circular "drop" cables.
[020] A face anterior 10a, da base 10, incorpora ainda, junto a sua segunda borda extrema 12, um par de garras laterais 30, as quais são projetantes para cima e elasticamente deformáveis, de uma posição operante, na qual travam o terminal de conexão TC contra a face anterior 10a da base 10, para uma posição inoperante, na qual liberam o terminal de conexão TC.  [020] The anterior face 10a, of the base 10, also incorporates, next to its second extreme edge 12, a pair of lateral claws 30, which are projecting upwards and elastically deformable, from an operating position, in which they lock the terminal TC connection plate against the front face 10a of the base 10, to an inoperative position, in which the TC connection terminal is released.
[021] A caixa ou roseta óptica compreende ainda uma tampa 60, geralmente formada em material não condutor elétrico e tendo uma parede anterior 61, paredes extremas 62 opostas entre si e paredes longitudinais 63, laterais e opostas entre si .  [021] The box or optical rosette further comprises a lid 60, generally formed of non-conductive electrical material and having an anterior wall 61, extreme walls 62 opposite each other and longitudinal walls 63, lateral and opposite each other.
[022] Cada uma das paredes extremas 62 é provida de uma janela 62a, sendo que, com a montagem da tampa 60 contra a base 10, uma das janelas 62a passa a envolver uma porção (extrema) do mordente 20, enquanto a outra janela 62a passa a envolver uma porção terminal de conexão TC que, geralmente, se projeta para fora da tampa 60, através da respectiva janela 62a. [023] A tampa 60 é construída para ter as bordas posteriores das paredes extremas 62 e longitudinais 63 assentadas e liberavelmente travadas contra a face anterior 10a da base 10, conforme ilustrado nas figuras 2 e 5. [022] Each of the end walls 62 is provided with a window 62a, and with the assembly of the cover 60 against the base 10, one of the windows 62a now surrounds a (extreme) portion of the clamp 20, while the other window 62a now surrounds a terminal connection portion TC which generally protrudes out of the lid 60, through the respective window 62a. [023] The cover 60 is constructed to have the rear edges of the extreme 62 and longitudinal walls 63 seated and reliably locked against the front face 10a of the base 10, as shown in figures 2 and 5.
[024] Para que a tampa 60 possa ser liberavelmente travada contra a face anterior 10a da base 10, as bordas longitudinais 13 dessa última podem ser providas, cada uma, por exemplo, de um par de linguetas de trava 15, incorporadas em peça única à base 10 e distanciadas longitudinalmente entre si e recuadas para dentro da respectiva borda da base 10, sob cada uma das quais é encaixado e retido um ressalto 65 incorporado internamente em cada parede longitudinal 63 da tampa 60, conforme melhor ilustrado na figura 5.  [024] So that the lid 60 can be releasably locked against the front face 10a of the base 10, the longitudinal edges 13 of the latter can be provided, each, for example, with a pair of locking tabs 15, incorporated in a single piece to the base 10 and spaced longitudinally from each other and recessed into the respective edge of the base 10, under which each shoulder 65 is embedded and retained internally in each longitudinal wall 63 of the lid 60, as best illustrated in figure 5.
[025] De acordo com a construção ilustrada, a porção do mordente 20, envolvida pela janela 62a da respectiva parede extrema 62 da tampa 60, apresenta um contorno igual ao da porção do terminal de conexão TC envolvida pela janela 62a da respectiva outra parede extrema 62 da tampa 60. Essa disposição permite que a tampa possa ser montada em dois posicionamentos opostos contra a base 10, ou seja, no posicionamento mais adequado à leitura de suas inscrições identificadoras, independentemente da inversão no posicionamento de fixação da base 10 na estrutura de sustentação da caixa ou roseta. Para tanto, as janelas 62a das duas paredes extremas 62 da tampa 60 são iguais e abertas na borda posterior de ditas paredes extremas 62a.  [025] According to the illustrated construction, the jaw portion 20, enclosed by the window 62a of the respective end wall 62 of the cover 60, has an outline similar to that of the portion of the TC connection terminal surrounded by the window 62a of the respective other end wall 62 of the cover 60. This arrangement allows the cover to be mounted in two opposite positions against the base 10, that is, in the position most suitable for reading its identifying inscriptions, regardless of the inversion in the positioning of the base 10 fixation in the structure. box or rosette support. For this purpose, the windows 62a of the two end walls 62 of the lid 60 are the same and open at the rear edge of said end walls 62a.
[026] Ainda de acordo com a configuração ilustrada, a face anterior 10a da base 10 pode incorporar, medianamente, duas nervuras 16, paralelas entre si, nas quais é assentado e guiado o conector extremo CE do cabo "drop" CD quando engatado no terminal de conexão TC travado contra a face anterior 10a da base 10. [026] Also according to the illustrated configuration, the front face 10a of the base 10 can incorporate, on average, two ribs 16, parallel to each other, on which the CE end connector of the CD "drop" cable is seated and guided when engaged with the TC connection terminal locked against the front face 10a of the base 10.
[027] Para fixação da base 10 em uma parede ou estrutura de sustentação, a base 10 pode ser feita, por exemplo, pela provisão de dois furos passantes 17, dimensionados para receberem respectivos parafusos de fixação não ilustrados ou mesmo pelo uso de uma fita adesiva dupla face, também não ilustrada .  [027] To fix the base 10 on a wall or support structure, the base 10 can be made, for example, by the provision of two through holes 17, dimensioned to receive respective fixing screws not illustrated or even by the use of a tape double-sided adhesive, also not shown.
[028] Com a construção aqui proposta, a base 10 é inicialmente fixada contra a estrutura de sustentação para então receber e travar, por meio das garras laterais 30, o terminal de conexão TC. Em seguida, o cabo "drop" CD, já carregando o conector extremo CE, tem esse último encaixado no confrontante extremo do terminal de conexão TC e uma porção de sua extensão encaixadas no interior do canal longitudinal C do mordente 20, para que os dentes 22 desse último interfiram com a capa externa do cabo "drop" CD, garantindo uma robusta retenção axial do cabo na caixa ou roseta .  [028] With the construction proposed here, the base 10 is initially fixed against the support structure to then receive and lock, through the lateral claws 30, the connection terminal TC. Then, the "drop" CD cable, already carrying the CE extreme connector, has the latter plugged into the end facing of the TC connection terminal and a portion of its extension fitted inside the longitudinal channel C of the clamp 20, so that the teeth 22 of the latter interfere with the external cover of the "drop" CD cable, ensuring a robust axial retention of the cable in the box or rosette.
[029] Após as operações de montagem da caixa e do cabo acima citadas, o usuário pode encaixar o plugue extremo PE de seu cordão óptico CO no interior do extremo do terminal de conexão TC acessivel através da respectiva janela 62a da tampa 60.  [029] After the aforementioned box and cable assembly operations, the user can fit the PE end plug of his CO optical cord inside the end of the TC connection terminal accessible through the respective window 62a of the cover 60.
[030] Apesar de ter sido aqui ilustrada apenas uma configuração da caixa de terminação ou roseta óptica em questão, deve ser entendido que poderão ser feitas alterações de forma e de disposição dos componentes, sem que se fuja do conceito construtivo definido nas reivindicações que acompanham o presente relatório.  [030] Although only one configuration of the termination box or optical rosette in question has been illustrated here, it should be understood that changes in the shape and layout of the components can be made, without departing from the constructive concept defined in the accompanying claims this report.
