Abstract

"APARELHO DE CONFINAMENTO DE EMI". Sistema de montagem de blindagem de EMI e RFI (24) inclui uma blindagem de EMI compartimentada (21) construída de uma termofórma metalizada a vácuo (22) tendo paredes ocas verticais separando e circundando os compartimentos (13). A blindagem (21) se adapta à parte interna de um alojamento (20) para o equipamento eletrónico (30), com as paredes verticais (29) sobrepondo-se os sulcos formados no interior do alojamento (20). Uma gaxeta compressível (25) é colocada entre os sulcos do alojamento e as extensões internas das paredes ocas (31) da blindagem (21). Os lados livres das paredes (29) da blindagem (21) podem ser confinados contra os traços de aterramento (46) numa placa de circuito impresso (32) na qual a blindagem (21) e o alojamento (20) estão colocados. A gaxeta (25) estimula as bordas livres metalizadas das paredes (29) da blindagem (21) contra os traços de aterramento (46) da placa de circuito impresso para proporcionar condutividade elétrica entre a placa de circuito impresso e a blindagem (21). Pequenas ondulações (60), abas (52) ou perfurações protuberantes podem ser formadas nos lados livres das paredes (29) para assegurar contato condutor com o traço de aterramento (46).
