차폐체 성형용 블랭크 및 차폐체

직교하는 두 방향으로 주기적으로 연속되는 요철로 이루어진 파형 모양이 겹쳐서 형성된 금속판(2, 3) 사이에 공극(4)이 형성된 요철 구조를 갖추고, 원하는 전개 형상으로 잘라 가지런해진, 둘레 가장자리를 되접어 이루어진 차폐체 성형용 블랭크에 의해서, 차열성, 차음성 등의 차폐 특성을 향상시킨 차폐체를 성형할 수 있다. Provided is a shield molding blank which has an uneven structure in which an air gap 4 is formed between metal plates 2...

Zusammenfassung:	직교하는 두 방향으로 주기적으로 연속되는 요철로 이루어진 파형 모양이 겹쳐서 형성된 금속판(2, 3) 사이에 공극(4)이 형성된 요철 구조를 갖추고, 원하는 전개 형상으로 잘라 가지런해진, 둘레 가장자리를 되접어 이루어진 차폐체 성형용 블랭크에 의해서, 차열성, 차음성 등의 차폐 특성을 향상시킨 차폐체를 성형할 수 있다. Provided is a shield molding blank which has an uneven structure in which an air gap 4 is formed between metal plates 2, 3 formed in overlapping wavy shapes comprising recesses and projections that are periodically continuous in two directions orthogonal to each other, the shield molding blank being cut in a desired expanded shape and having peripheral edges folded. With the shield molding blank, it is possible to mold a shield having improved shield characteristics such as a heat-shielding property and a sound-shielding property.
