Description

ENCAIXE DE VEDAÇÃO DE CAIXABOX SEAL FITTING
A presente invenção refere-se a um encaixe de vedação de caixa, utilizado particularmente para vedar caixas de terminação óptica (CTO) através basicamente de uma peça encaixada entre a base e a tampa da caixa.The present invention relates to a box seal fitting, particularly used to seal optical termination boxes (CTO) through basically a piece fitted between the base and the cover of the box.
DESCRIÇÃO DO ESTADO DA TÉCNICADESCRIPTION OF THE STATE OF THE TECHNIQUE
As redes de fibra óptica utilizam, entre outros componentes, caixas de emenda óptica (CEO) e caixas de terminação óptica (CTO), de onde são distribuídos cabos de fibra óptica para os usuários finais. Dentro dessas caixas, o cabo de entrada é separado em diversas fibras e também dividido por “splitters”, dentro de uma caixa de alojamento de fibras, para finalmente ser conectado a um adaptador de fibra óptica, o qual permite que seja conectado um cabo óptico de terminação (cabo “drop”) para a conexão ao usuário.Optical fiber networks use, among other components, optical splice boxes (CEO) and optical termination boxes (CTO), from where fiber optic cables are distributed to end users. Inside these boxes, the input cable is separated into several fibers and also divided by "splitters", inside a fiber housing box, to finally be connected to an optical fiber adapter, which allows an optical cable to be connected. termination cable (drop cable) for connection to the user.
Portanto, resumidamente, nas caixas de terminação óptica (CTO) entram cabos de entrada, que são divididos por “splitters” e saem os cabos terminais, ou “cabos drops” para os usuários finais.So, in short, the optical termination boxes (CTO) enter input cables, which are divided by “splitters” and leave the terminal cables, or “drop cables” for the end users.
Para que as CTO funcionem adequadamente, é de extrema importância que suas entradas e saídas sejam corretamente vedadas, mantendo a caixa estanque, impedindo a entrada de água, insetos ou sujidades. In order for the CTO to function properly, it is extremely important that their inlets and outlets are correctly sealed, keeping the housing watertight, preventing the entry of water, insects or dirt.
Como exemplo de encaixes de vedação do estado da técnica, existem documentos de patente tal como o BR 102019014363-0, que mostra um encaixe de vedação, além da caixa, que compreende 3 elementos: um batoque de vedação, que é encaixado em um rebaixo da borda da base da caixa; um elemento de ancoragem, que é assentado sobre dito batoque de vedação; e, encaixado no referido elemento de ancoragem tem-se um elemento de vedação. O batoque de vedação é encaixado no rebaixo das entradas de cabos. Para possibilitar a instalação de diversos diâmetros de cabos sem folga entre o cabo e o respectivo furo do batoque, o fabricante deve fornecer batoques com diferentes padrões diametrais, os quais devem ser escolhidos pelo técnico de acordo com o diâmetro do cabo a instalar para a correta instalação sem folga, ou seja, para que os cabos sejam instalados sem folga entre os cabos e os furos do batoque. Além disso, o técnico deve também alinhar corretamente o elemento de vedação no elemento de ancoragem, para que os cabos “drop” se encaixem corretamente nos rasgos do elemento de vedação. Dito elemento de vedação apresenta uma parede, a qual é rompida no encaixe de um cabo “drop”, mantendo os rasgos não utilizados vedados. Ou seja, se for encaixado um cabo “drop” em um rasgo incorreto, e depois este rasgo for inutilizado, o elemento de vedação deverá ser trocado, pois não vedará corretamente a caixa uma vez que foi rompido quando da tentativa de encaixe do cabo “drop”. Como é possível notar, este tipo de encaixe de vedação apresenta muitas peças e etapas de instalação, aumentando as chances de erros, além de ser necessário o fornecimento de peças sobressalentes, as quais no final da instalação serão inutilizadas.As an example of state-of-the-art sealing inserts, there are patent documents such as BR 102019014363-0, which shows a sealing insert, in addition to the box, which comprises 3 elements: a sealing stopper, which is fitted into a recess from the edge of the base of the box; an anchoring element, which is seated on said sealing bung; and, fitted to said anchoring element is a sealing element. The sealing stopper fits into the recess of the cable entries. To enable the installation of different diameters of cables without gap between the cable and the respective hole of the toggle, the manufacturer must supply toggles with different diametrical patterns, which must be chosen by the technician according to the diameter of the cable to be installed for the correct gap-free installation, i.e. so that the cables are installed without gap between the cables and the holes of the bung. In addition, the technician must also correctly align the sealing element on the anchor element so that the drop cables fit correctly into the sealing element slots. Said sealing element has a wall, which is broken in the fitting of a “drop” cable, keeping the unused slots sealed. That is, if a “drop” cable is fitted into an incorrect slot, and then this slot is rendered useless, the sealing element must be changed, as it will not properly seal the box since it was broken when trying to fit the cable “ drop”. As you can see, this type of seal fitting has many parts and installation steps, increasing the chances of errors, in addition to the need to supply spare parts, which at the end of the installation will be unusable.
O documento BR102018005815-0 mostra um encaixe de vedação similar ao revelado em BR 102019014363-0, porém ao invés de utilizar o batoque de vedação são utilizadas buchas de vedação. Da mesma forma como o batoque de vedação, devem ser fornecidas buchas com furos de diversos diâmetros para que sejam escolhidas buchas de tamanho de furo adequado para cada diâmetro de cabo específico, para que ao passar o cabo não se tenha nenhum espaço livre ao redor do cabo. Assim, os mesmos problemas do encaixe de vedação do BR 102019014363-0 também estão presentes no BR102018005815-0.Document BR102018005815-0 shows a sealing fitting similar to that revealed in BR 102019014363-0, however, instead of using the sealing stopper, sealing bushes are used. In the same way as the sealing stopper, bushings with holes of different diameters must be provided so that bushings with the appropriate hole size are chosen for each specific cable diameter, so that when passing the cable there is no free space around the cable. cable. Thus, the same problems of the seal fitting of the BR 102019014363-0 are also present in the BR102018005815-0.
Assim, para solucionar os problemas e desvantagens das vedações da arte anterior, a presente invenção apresenta um encaixe de vedação de caixa que simultaneamente veda os cabos “drop” e os cabos de entrada, através de uma única peça a ser instalada nas entradas e saídas de cabos da caixa.Thus, to solve the problems and disadvantages of the prior art seals, the present invention presents a box seal fitting that simultaneously seals the drop cables and the input cables, through a single piece to be installed in the inlets and outlets. box cables.
