Abstract

CIRCUITO PARA DISPOSITIVOS DE PROTEçãO CONTRA SURTOS EM TELEFONE DE USO PúBLICO. Que com apenas uma única configuração de circuito, placa de circuito impresso e conectores, permite o encaixe em vários modelos de diversos modelos de TUP, apresentando dispositivo de proteção contra surtos (DPS) dotado de elementos de proteção EP1 e EP2, respectivamente centelhador tripolar a gás e tiristor supressor de surto com corrente de manutenção superior a cento e oitenta miliampere (IH > 180 mA). Poderá também apresentar dispositivo de proteção contra surtos (DPS) dotado de elementos de proteção EP1 e EP2, utilizando como EP1 uma associação de série de bipolares com o ponto comum como terceiro pólo, e EP2 tiristor supressor de surto com corrente de manutenção superior a cento e oitenta miliampere (1H > 180 mA). Apresenta fusíveis PTC1 e PTC2, regeneráveis, para proteção contra sobre-corrente nas linhas LA e LB. As sobretensões geradas pelos surtos elétricos vindos pelas linhas de comunicação LA e LB provocarem a atuação do elemento de proteção EPI, que faz a proteção em modo comum entre a linha LA e o terra e entre a linha LB e o terra; em que o componente EP2 fará proteção em modo transversal, ou seja, entres as linhas LA e LB; os componentes PTC1 e PTC2 apresentam impedância em conduções normais de operação e, em caso de sobre-correntes em LA ou LB, atuam como fusíveis regeneráveis. Os elementos A, B, O, D e E representam os orifícios de encaixe na placa de circuito impresso, que permitem a instalação e fixação da placa em telefones públicos de vários fabricantes e modelos, via parafusos. A entrada da linha privada de comunicação para o circuito de proteção se dá via conector CON1, sendo sugerido como exemplo na configuração ilustrada, o conector tipo alavanca. Nesse conector, quando lhe é exercida uma força sobre as alavancas, o canal de conexão se abre permitindo o encaixe e inserção dos fios de conexão do telefone. A saída da linha privada de comunicação do circuito de proteção se dá via CON2, sendo sugerido como exemplo na configuração ilustrada, o conector tipo RJ11 de saída. CIRC é o circuito de proteção.CIRCUIT FOR SURGE PROTECTION DEVICES IN A PUBLIC USE PHONE. With just a single circuit configuration, printed circuit board and connectors, it allows to fit several models of various TUP models, featuring surge protection device (DPS) with protection elements EP1 and EP2, respectively three-pole spark arrester. gas and surge suppressor thyristor with a maintenance current exceeding one hundred eighty milliamperes (IH> 180 mA). It may also feature a surge protection device (DPS) fitted with EP1 and EP2 protection elements, using EP1 as a series association of bipolar with the common point as the third pole, and EP2 surge suppressor thyristor with a maintenance current greater than one hundred. and eighty milliamperes (1H> 180 mA). Features PTC1 and PTC2 regenerable fuses for overcurrent protection on the LA and LB lines. Overvoltages generated by electrical surges coming from the communication lines LA and LB cause the protection element EPI to actuate, which protects in common mode between the line LA and the ground and between the line LB and the earth; wherein the EP2 component will provide transverse protection, ie between lines LA and LB; PTC1 and PTC2 components have impedance under normal operating conditions and, in case of overcurrent in LA or LB, act as regenerable fuses. Elements A, B, O, D and E represent the holes in the PCB that allow the card to be installed and fixed in payphones of various manufacturers and models via screws. The private communication line input to the protection circuit is via connector CON1, being suggested as an example in the illustrated configuration, the lever connector. In this connector, when a force is exerted on the levers, the connection channel opens allowing the connection and insertion of the telephone connection wires. The private circuit communication line output of the protection circuit is via CON2, being suggested as an example in the illustrated configuration, the RJ11 type output connector. CIRC is the protection circuit.
