Abstract

BATERIA ALCALINA SECA. É revelada uma bateria alcalina seca à prova de vazamento que inclui um invólucro da bateria e uma unidade de vedação para fechar a abertura do invólucro da bateria. A unidade de vedação inclui: uma placa de terminal do eletrodo negativo, um pino do coletor de corrente do eletrodo negativo conectado eletricamente na placa de terminal, e um elemento de vedação de resina, O elemento de vedação de resina inclui: uma parte cilíndrica central que tem uma abertura pela qual o corpo do pino do coletor de corrente do eletrodo negativo é inserido, uma parte cilíndrica periférica externa disposta entre uma borda periférica da placa de terminal do eletrodo negativo e uma borda aberta do invólucro da bateria, uma parte de conexão que interconecta as partes cilíndricas periféricas central e externa, e uma seção mais fina formada na parte de conexão. O corpo do pino do coletor de corrente do eletrodo negativo é encaixado na abertura da parte cilíndrica central em uma relação de encaixe particular para impedir vazamento por um longo tempo.
