Description

부동식 자기헤드의 짐발 스프링
제 1 도는 본 고안의 짐발 스프링을 포함하는 부동식 자기 헤드의 구성을 나타낸 사시도.
제 2 도는 동 측면도.
제 3 도는 플랙서(flexure)의 평면도.
제 4 도는 종래예의 구성을 나타낸 사시도이다.
* 도면의 주요부분에 대한 부호의 설명
1 : 로드비임 1a : 절곡부
2 : 보강판 3 : 플랙서(flexuer)
5 : 부동식 자기헤드 5a : 부동식자기헤드의 매체대향면
10 : 짐발스프링
본 고안은 부동식 자기헤드의 짐발 스프링 구조에 관한 것이다.
제 4 도는 종래의 부동식 자기헤드를 짐발스프링에 설치한 구조를 나타내는 사시도이다. 종래의 자기헤드(5)의 짐발스프링(10)에 설치된 구조는 상기 짐발스프링(10)의 선단에, 예를들면 용접등으로 고정시킨 플랙서(flexuer)를 거쳐 접착제나 합성수지 등에 의하여 고착되어 있고, 또 짐발 스프링(10)의 구조는 로드비임(1)과 마운트(4)로 구성되고, 상기 로드비임(1)의 양측단에는 자기헤드(5)의 설치측의 반대측 방향으로 절곡된 절곡부(1a,1b)가 로드비임(1)의 선단까지 형성되어 있다. 또 그 절곡부(1a,1a)의 내측에는 리이드선(20)이 유지되어 있다.
자기 디스 구동장치(도시 생략)에 있어서는 복수매의 자기 디스크가 장착되어 있고 그 자기 디스크 구동장치의 크기, 특히 두께를 결정하는 요인으로써 부동식 자기헤드(5), 짐발 스프링(10)의 높이가 있다.
그러나, 종래의 짐발스프링(1)의 구조에서는 로드비임(1b)의 절곡부(1a,1a)의 방향이 부동식 자기헤드(5)의 반대방향에 있어 그 내측 리이드선(20)이 배설(配設) 되어 있기 때문에 절곡부(1a,1a)의 높이가 직접 짐발스프링(1)을 포함한 부동식 자기헤드(5)의 두께에 관여하여 자기 디스크구동장치의 두께를 결정한다는 결점이있다.
본 고안은 이러한 결점을 감안하여 이루어진 것으로서 부동식 자기헤드를 지지하는 짐발 스프링의 구조에 있어서, 짐발 스프링의 로드비임의 양측단을 상기 부동식 자기헤드의 설치측을 절곡한 절곡부를 형성한 것을 특징으로 하는 부동식 자기 헤드의 짐발 스프링이다.
짐발 스프링의 로드 비임의 절곡방향을 부동식 자기헤드의 설치측으로 함으로써 절곡의 높이가 짐발스프링을 포함한 부동식 자기헤드의 두께에 관여하지 않게 되고, 또 절곡부가 로드비임 선단부까지 형성되지 않고 로드비임의 선단부의 강도가 약해지나, 로드 비임의 선단부의 부동식 자기헤드와 반대측에 보강판을 설치고정함으로써 이것을 보완한다.
이하 본 고안의 일실시예에 관하여 도면을 참조하면서 상세히 설명한다.
제 1 도는 본 고안을 나타내는 사시도, 제 2 도는 동측면도이다.
도면에 있어서, 짐발스프링(10)은 로드비임과 보강판(2)과 플랙서(3)와 마운트(4)로서 이루어지고, 플랙서(3)의 선단에는 부동식 자기헤드(5)가 설치되어 있다.
또 부동식자기헤드(5)에는 코일(6a)이 형성되어 있고, 그 양단의 리이드선(6)은 가요성, 프린트기관(7)에 접속되어 있다. 로드비임(1)의 양측연부는 부동식 자기헤드(5)측 바꾸어 말하면 매체 대향면(5a)측으로 절곡된 절곡부(1a),(1a)가 형성되어 있다. 이 절곡부(1a,1a)는 플랙서(3)의 근처까지 뻗어 있으나, 부동식 자기헤드(5)가 설치되어 있는 로드비임(1) 선단부까지는 미치지 않기 때문에 로드비임(1) 선단부가 약해지고, 이것을 보강하기 위하여 보강판(2)이 로드비임(1)과 용접 등의 수단에 의하여 부동식 자기헤드(5)와 반대측에 설치되고, 또한 플랙서(3)가 로드비임(1)의 부동식 자기헤드(5)측에 같은 수단에 의하여 설치되어 있다.
또, 이 플랙서(3)에는 제 3 도에 나타낸 바와 같이 홈(3a)이 에칭 등의 수단에 의하여 형성되고, 부동식 자기 헤드(5)와의 접착면(3c)과 로드비임(1)에의 설치면(3d) 이 평행이 되도록 또 접착면(3c)과 설치면(3d) 을 연결하는 연결면(3b)을 형성하는 Z구조를 이루고 있다.
또 가용성, 프린트기관(7) 은 예를 들면 제1도에 나타낸 바와 같이 로드비임(1)의 부동식 자기헤드(5)측, 다시말하면 매체 대향면(5a)측에 로드비임(1)의 마운트 방향으로 향하여 설치되어 있고, 마운트(4) 부근에서 직각으로 구부려, 절곡부(1a)와 마운트(4)와의 갈라진 틈으로 부터 외측으로 인출되는 자기 디스크 장치의 회로에 접속되어 있다.
이상 설명한 바와 같이 본 고안에 의하면 로드비임(1) 의 절곡부(1a,1a)가 부동식 자기헤드(5) 측에 절곡되어 있기 때문에, 짐발 스프링을 포함한 부동식 자기헤드의 두께에는 관여하지 않게 되어 박형화(薄型化)가 도모됨과 동시에 매체의 간격을 좁게 할 수 있기 때문에 자기 디스크 구동장치의 소형화에의 대응에도 충분히 가능하다.
