Description

VTR에 있어서 상부 드럼의 헤드와 상부 로우터리 트랜스와의 접속장치Connecting device between upper drum head and upper rotary transformer in VTR

제1도는 본 고안의 분해사시도.1 is an exploded perspective view of the present invention.

제2도는 조립상태의 평면도와 단면 예시도.2 is a plan view and a cross-sectional view of the assembled state.

제3도는 종래 방법에 의한 조립 평면도와 그 단면예시도.3 is an assembled plan view and a cross-sectional view of the conventional method.

본 고안은 VTR에 있어서 윗드럼의 헤드와 그 로우터리 트랜스간을 도선과 납땜없이 용이하게 접속되게 한 접속장치에 관한 것이다.The present invention relates to a connecting device in which the head of the upper drum and its rotary transformer are easily connected to each other in the VTR without soldering.

종래에는 제3도에 표시된 바와 같이 상부 로우터리 트랜스(1)의 코일끝을 그 위에 얹힌 기판(2)에 납땜 고정하고, 상기 코일의 다른 끝은 상부 로우터리 트랜스(1)의 윗면에 부착된 프랜지(4)의 관통구멍(5)으로 빼낸다음 상부 드럼(6)의 윗면에 양면테이프로 붙인 기판(7)에다가 납땜 고정한다.Conventionally, as shown in FIG. 3, the coil end of the upper rotary transformer 1 is soldered and fixed to the substrate 2 mounted thereon, and the other end of the coil is attached to the upper surface of the upper rotary transformer 1. It is pulled out through the through hole 5 of the flange 4 and soldered to the substrate 7 attached to the upper surface of the upper drum 6 with double-sided tape.

그리고 단자(10)는 상부 드럼(6)의 수직 삽입공(8)에 끼운 다음 위아래끝을 각각 기판(7)과 헤드몸체(9)에 납땜 고정하여 헤드와 로우터리 트랜스(1)를 접속시킨 것이다.The terminal 10 is inserted into the vertical insertion hole 8 of the upper drum 6, and then the upper and lower ends are soldered and fixed to the substrate 7 and the head body 9, respectively, to connect the head and the rotary transformer 1 to each other. will be.

이와 같이 각 접속부위를 납땜으로 고정하는 것은 서어비스 부품인 상부드럼을 교체할때 모든 납땜을 제거해야만 분해 가능하므로 교체작업이 불편하고 이때 자칫 다른 부품이 피해를 입기 쉬우며, 전반적으로 부품수와 상부드럼의 가공부위가 많은 결점이 있다.As described above, fixing each connection part by soldering can be done by removing all soldering when replacing the upper drum, which is a service part, and thus it is inconvenient for replacement work, and other parts are easily damaged. The machining part of the drum has many drawbacks.

본 고안은 바로 이같은 결점을 해소한 것으로, 제1도 및 제2도에서 보는 바와 같이 상부 로우터리 트랜스(1)내에 있는 코일은 그위에 얹힌 기판(2)의 납땜 고정되어 있고 그자리에 도체인 접촉편(11)이 부착되어 있다.The present invention solves this shortcoming. As shown in Figs. 1 and 2, the coil in the upper rotary transformer 1 is soldered and fixed in place on the substrate 2 placed thereon. The contact piece 11 is attached.

그리고 이 접촉부(11) 윗면에는 코일스프링 형태의 접촉자(12)가 얹히며, 이 접촉자(12)는 절연고정틀(13)의 수직 삽입공(14)에 끼워져 일정한 제위치를 유지하게 되어 있다.And the upper surface of the contact portion 11 is placed a coil spring type contactor 12, the contactor 12 is fitted into the vertical insertion hole 14 of the insulating fixing frame 13 to maintain a constant position.

한편, 상기 고정틀(13)의 밑면에는 아래쪽은 튀어나온 핀(15)이 있으며 이 핀(15)은 상기 기판(2)의 홈(16)에 끼워져서 고정틀(13)이 멋대로 동요하지 않도록 방지한다.On the other hand, the bottom of the fixing frame 13 has a pin 15 protruding from the bottom of the fixing frame 13 is inserted into the groove 16 of the substrate 2 to prevent the fixing frame 13 from shaking freely. .

또 상기 접촉자(12)의 위끝은 헤드몸체(9)의 저면의 단자(10)가 고정된 자리에 형성한 접촉자(17)에 맞닿게 해서 이들 양 접촉부(11)(17)를 접속시킨 것이다.The upper end of the contactor 12 is brought into contact with the contactor 17 formed at the position where the terminal 10 of the bottom surface of the head body 9 is fixed, thereby connecting both contact portions 11 and 17.

이와 같이 구성된 본 고안에 있어서 접촉자(12)는 코일 스프링성 탄력을 갖고 있으므로 항상 일정한 탄성으로 헤드몸체(9)의 접촉부(17)와 기판(2)의 접촉부(11)를 전기적으로 연결하여 준다.In the present invention configured as described above, the contactor 12 has a coil spring-like elasticity, thereby electrically connecting the contact portion 17 of the head body 9 and the contact portion 11 of the substrate 2 with constant elasticity.

더우기, 상기 접촉자(12)는 기판(2)의 접촉부(11)와 헤드몸체(9)의 접촉부(17)에 다같이 납땜에 위하지 않고 단순 접촉만으로 양 접촉부(11)(17)를 전기적으로 연결해주기 때문에 상부드럼(6)만 들어내면 곧바로 헤드몸체(9)와 접촉자(12) 그리고 상부 로우터리 트랜스(1)의 기판(2)은 완전 분리된다.Furthermore, the contactor 12 electrically contacts both the contact portions 11 and 17 with only a simple contact, not for soldering, together with the contact portion 11 of the substrate 2 and the contact portion 17 of the head body 9. As soon as the upper drum 6 is lifted off, the head body 9, the contactor 12 and the substrate 2 of the upper rotary transformer 1 are completely separated.

따라서 본 고안에 의하면 헤드몸체와 로우터리 트랜스간의 전기적 접속에 있어서 도선을 이용한 납땜부위가 전무하고, 상부 로우터리 트랜스의 플랜지에 도선이 통과할 구멍을 뚫어 필요도 없는 만큼 부품수와 작업공수가 감출될뿐만 아니라 상부드럼을 교체할때 분해하기도 한결 수월하며, 아울러 상부드럼 교체작업시에 부근의 다른 부품 안전에도 큰 도움이 된다.Therefore, according to the present invention, there are no soldering parts using conductors in the electrical connection between the head body and the rotary transformer, and the number of parts and workmanship are hidden as there is no need to drill a hole for the conductor to pass through the flange of the upper rotary transformer. Not only is it easy to disassemble when replacing the upper drum, it is also very helpful for the safety of other parts in the vicinity when replacing the upper drum.
