일반적으로 VCR등 각종 기록매체에 사용되는 자기헤드는 자기테이프, 자기디스크, 자기드럼등의 자성면에 정보를 기록 판독 소거시키는 부품으로서, 전기신호를 자기로 바꾸어 매체상에 녹음하기 위한 녹음헤드와, 자기 녹음된 신호를 전기 신호로 끄집어 내기위한 재생헤드와, 자기 녹음된 신호를 자기적으로 소거시키기 위한 소거헤드로 대별된다.In general, magnetic heads used in various recording media such as VCRs are components for recording and erasing information on magnetic surfaces such as magnetic tapes, magnetic disks, magnetic drums, and the like. And a reproduction head for picking up the magnetically recorded signal into an electrical signal and an erasing head for magnetically erasing the magnetically recorded signal.
따라서 상기 각 헤드는 자성을 형성하기 위하여 코일이 권선되는 보빈과, 상기 보빈에 삽입 고정되어 각 신호를 외부 회로와 연결을 위한 단자핀이 구비되는 것이다.Therefore, each head is provided with a bobbin in which a coil is wound to form a magnet, and a terminal pin inserted into and fixed to the bobbin to connect each signal to an external circuit.
제1도(A), (B)는 종래의 자기헤드의 보빈 구성을 나타낸 사시도로서, 도시된 바와같이 보빈(10)은 코일이 권선되는 권치부(11)와 권취부(11) 배면에 단자핀 삽입부재(15)가 일체로 형성된 것이다.1 (A), (B) is a perspective view showing the bobbin configuration of a conventional magnetic head, as shown in the bobbin 10 is a terminal on the back of the winding portion 11 and the winding portion 11 is wound coil Pin insertion member 15 is formed integrally.
상기에서 권취부(11)는 횡 방향으로 중공(13)이 형성되고 전면에는 권선된 코일의 이탈을 방지하기 위하여 단(12)이 형성된 것이다.In the winding portion 11 is a hollow 13 is formed in the transverse direction and the front end is formed with a stage 12 in order to prevent the winding of the coil.
그리고, 단자핀 삽입부재(15)에는 단자핀(20)이 삽입고정 되도록, 상.하단이 연통된 단자핀 삽입공(16)이 형성되며 양측면에는 도시되지 않은 쉴드 케이스 내에 조립되도록 상. 하단을 잇는 안내레일(14)이 형성된 것이다.And, the terminal pin insertion member 15 is formed so that the terminal pin 20 is inserted and fixed, upper and lower terminal pin insertion hole 16 is communicated with the upper and lower sides to be assembled in a shield case (not shown). Guide rails 14 connecting the lower end is formed.
상기한 종래의 보빈(10)은 단자핀(20)이 단자핀 삽입공(16)에 삽입되어 고정되도록 단자핀(20) 외주면을 코킹(25)하여 단자핀(20)이 단자핀 삽입공(16)에 억지 끼워맞춤 되도록한 것이다.The above-described conventional bobbin 10 is caulking the outer peripheral surface of the terminal pin 20 so that the terminal pin 20 is inserted into the terminal pin insertion hole 16, the terminal pin 20 is a terminal pin insertion hole ( 16) to be fit.
그러나 단자핀(20)의 억지 끼워맞춤은 단자핀(20)에 무리한 하중이 가해져 단자핀(20)의 휨 현상을 발생시키는 문제점이 되었다.However, the interference fit of the terminal pin 20 is a problem that the excessive force is applied to the terminal pin 20 to cause the bending of the terminal pin 20.
다른 문제점은 억지 끼워맞춤시 코킹(25) 부위가 박리되어 단자핀(20)이 단자핀 삽입공(16)으로 부터 유동 또는 이탈되는 것이다.Another problem is that the caulking 25 is peeled off during the interference fit so that the terminal pin 20 flows or escapes from the terminal pin insertion hole 16.
또 다른 문제점은 권취부(11)에 형성된 중공(13)과 단자핀 삽입부재(15)에 형성된 단자핀 삽입공(16)이 상호 직교되는 지점에 위치 함으로서, 보빈(10)의 제품생산시 사출 압력에 따라 상기 부위의 불량이 발생되어 후가공의 추가공정을 요하는 것이다.Another problem is that the hollow 13 formed in the winding part 11 and the terminal pin insertion hole 16 formed in the terminal pin insertion member 15 are located at orthogonal to each other, so that the injection of the bobbin 10 during production of the product is performed. According to the pressure, the defective part of the part is generated, which requires an additional step of post processing.
제2도(A), (B)는 종래의 자기헤드의 보빈 구성을 나타낸 다른 실시예의 사시도로서 도시된 바와같이 단자핀 삽입부재(15) 전면에 단자핀 삽입공(16)과 연통된 수직절결부(17)가 형성된 것이다.2 (A) and (B) is a vertical section in communication with the terminal pin insertion hole 16 in front of the terminal pin insertion member 15 as shown in a perspective view of another embodiment showing a bobbin configuration of a conventional magnetic head. The joint 17 is formed.
따라서 단자핀(20)을 단자핀 삽입공(16)에 헐거운 끼워 맞춤후 수직절결부(17)를 통해 단자핀(20)의 상측면을 코킹(18)하며 단자핀 삽입공(16) 하단부로 일정범위 돌출된 단자핀(20)을 코킹(18a)하여 단자핀(20)을 단자핀 삽입공(16)에 고정하는 것이다.Therefore, after loosely fitting the terminal pin 20 to the terminal pin insertion hole 16, the upper side of the terminal pin 20 through the vertical cutout 17 and caulking (18) to the lower end of the terminal pin insertion hole (16) The terminal pin 20 is fixed to the terminal pin insertion hole 16 by caulking a predetermined range of the terminal pin 20 (18a).
이러한 후코킹방식은 단자핀(20)이 단자핀 삽입공(16)에 억지 끼워맞춤시 발생하는 문제점을 개선한 점이 있으나 삽입후 수직 절결부(17)를 통해 단자핀(20)을 코킹(18)(18a)하게 되어 코킹위치 선정 및 코킹작업이 매우 어려워 단자핀(20)이 유동되는 등 고정이 불안정한 문제점이 있었다.This post-caulking method has the problem that the terminal pin 20 has been improved when the interference fit to the terminal pin insertion hole 16 has been improved, but caulking the terminal pin 20 through the vertical notch 17 after insertion (18) (18a) has been a problem that the fixing position is unstable, such as the caulking position selection and caulking operation is very difficult, such that the terminal pin 20 is flowed.
또한 코킹(18)(18a) 압착력이 강할 경우 단자핀(20)이 구부러지거나 절단되는 등 또 다른 문제점이 있었다.In addition, when the crimping force of the caulking (18) (18a) is strong, there was another problem such as the terminal pin 20 is bent or cut.
특히 보빈(10)의 사출압력에 따른 제품의 트러블은 개선되지 않는 것이다.In particular, the trouble of the product according to the injection pressure of the bobbin 10 is not improved.
