Abstract

"SISTEMA DE AUTOGABARITO PARA UM INTERRUPTOR DE VáCUO". A invenção refere-se a um interruptor de vácuo (1000) aperfeiçoado. O interruptor de vácuo (1000) inclui coberturas de extremidade (1005) que tem uma porção curva ou em laço (1022), as quais servem para conectar um segmento de bobina (1015) do interruptor de vácuo (1000) a um envelope cerâmico (1010) do interruptor de vácuo (1000), e por meio disto ajudar a manter uma vedação de vácuo para o interruptor. A porção curva (1022) atua como uma mola quando o interruptor de vácuo (1000) está exposto ao calor, por meio disto absorvendo qualquer expansão ou contração no comprimento do interruptor de vácuo devido ao aquecimento ou resfriamento. A porção curva (1022) também protege uma extremidade do envelope cerâmico (1010) de qualquer acúmulo de produtos de formação de arco metálicos e elimina a necessidade de gabaritos elaborados durante a montagem. Além disso, uma guia (1045) pode estar afixada na cobertura de extremidade (1005), a guia (1045) tendo orelhas (1302) as quais deslocam-se dentro de um rasgo (1050) em uma haste móvel (1035) do interruptor de vácuo (1000), para por meio disto impedir uma torcedura de um fole (1030) do interruptor durante um processo de brazagem. Assim, nenhum gabarito elaborado é necessário para impedir esta torcedura.
