Abstract

본 발명은 절첩선에서 서로 부착된 부분 코일 회선을 금속 시트로부터 절단하여 형성한, 고주파·고전력 변압기 연결용 헬리컬 유도 코일에 관한 것이다.The present invention relates to a helical induction coil for high frequency and high power transformer connection, formed by cutting partial coil lines attached to each other at a fold line from a metal sheet.

폭/두께 비는 10이상이다. 절단 후 블랭크는 절첩되어, 부분 코일 회선이 부분적으로 서로 중첩되어서 각각의 헬릭스 부분이 모재 금속 내의 절첩부에 의해 서로 부착된 헬릭스를 형성하도록 한다. 헬릭스는 양호하게는 완성시 원형 코일이 된다.The width / thickness ratio is more than 10. After cutting the blanks are folded so that the partial coil convolutions partially overlap each other such that each helix portion forms a helix attached to each other by a fold in the base metal. The helix is preferably a circular coil at completion.
