본 고안은 비데오 테이프 레코더의 헤드드럼에 관한 것으로 특히 신호 전달체계를 외부의 전기적인 잡음으로부터 차단하여 양질의 화면을 재생하고 홀더를 제거하여 제품의 소형 경량화와 함께 원가 절감과 생산성 향상에 기여할 수 있도록 개선된 헤드드럼에 관한 것이다.The present invention is related to the head drum of the video tape recorder. In particular, the signal transmission system can be cut off from external electrical noise to reproduce high-quality screens and remove the holders. An improved head drum is disclosed.

종래의 비데오 테이프 헤드드럼은 제 1 도에서 보는 바와 같이 회전 드럼(31)의 저면 양측에 헤드(33)(33')를 부착하였고 내부에는 터미널(34)을 형성하여 상면에 고정 부착된 중계기판(35)와 연결되어 플랜지(39)에 안착 되었다.In the conventional video tape head drum, as shown in FIG. 1, a head 33 (33 ') is attached to both sides of the bottom surface of the rotating drum 31, and a terminal 34 is formed therein to fix the upper surface of the relay board. It is connected to (35) and seated on the flange (39).

그리고 플랜지(39)의 저면에는 회동 트랜스(40)가 부설되어 플랜지(39)를 상하로 관통시킨 와이어(38)로 중계기판(35)과 연결되었으며, 상면에 고정트랜스(41)를 부착한 고정 드럼(32)의 일측면에는 홀더(50)가 부설되어 내부를 관통하여 나온 신호선(51)으로 상면에 설치된 신호전달 콘넥터(43)와 연결되었다.In addition, a rotation transformer 40 is installed on the bottom of the flange 39 and connected to the relay board 35 through a wire 38 through which the flange 39 penetrates up and down. The fixing transformer 41 is attached to the upper surface. The holder 50 is attached to one side of the drum 32 and connected to the signal transmission connector 43 installed on the upper surface by a signal line 51 penetrating through the inside.

또한 고정드럼 (32)의 중앙에는 샤프트(37)가 돌출되어 회동용 모터(42)와 결합설치되었으며 하부에는 콘넥터(49)를 부설한 취부판(48)이 삽입 고정 되었다.In addition, in the center of the fixed drum 32, the shaft 37 protrudes and is installed in combination with the rotational motor 42, and a mounting plate 48 having a connector 49 installed therein is fixedly inserted therein.

상기의 구성에 따른 동작을 설명하면 회동용 모터(42)로 부터 동력을 전달 받은 샤프트(37)가 회전드럼(31)을 고속회전 시켜 줄때 헤드(33), (33')에서 감지된 신호가 터미널(34)과 중계기판(35)을 거쳐 와이어(38)로 회동트랜스(40)에 연결되며 다시 고정트랜스(41)를 통하여 신호선(51)으로 홀더(50)외 상면에 콘넥터(43)에 전달되었다.Referring to the operation according to the above configuration, when the shaft 37 receives the power from the rotating motor 42 to rotate the rotating drum 31 at high speed, the signal detected by the head 33, 33 ' It is connected to the rotation transformer 40 by the wire 38 via the terminal 34 and the relay board 35, and is connected to the connector 43 on the upper surface of the holder 50 by the signal line 51 through the fixed transformer 41. Delivered.

따라서 상기의 신호 전달체계는 그 구성이 복잡, 난해하고 많은 부품이 소요됨으로 작업시 시간과 인력의 낭비가 많았을 뿐 아니라 접속부재인 신호전달 콘넥터(43)의 고정을 위한 별도의 홀더(50)가 부설되어 제품의 소형 경량화 추세에 어긋나는 등의 문제점이 있었다.Therefore, the signal transmission system is complicated, difficult and difficult to take a lot of components due to its complicated configuration, and a separate holder 50 for fixing the signal transmission connector 43, which is a connection member. There was a problem that the installation is contrary to the trend of small size and light weight of the product.

이러한 종래의 문제점을 해결하기 위하여 안출한 본 고안의 구성은, 제 2 도와 제 3 도에서 보는 바와같이 회전 드럼(1)의 저면 양측에 헤드(3)(3')를 부착하고 내부에는 터미널(la)을 형성하여 플랜지(9)를 상하로 관통시 킨 와이어 (8)로 회동트랜스(10)에 연결하고 플랜지(9)에 안착된다.The construction of the present invention devised to solve such a conventional problem, as shown in Figure 2 and 3, the head (3) (3 ') is attached to both sides of the bottom surface of the rotating drum (1) and the terminal ( La is formed to connect to the rotating transformer 10 by the wire (8) through the flange (9) penetrated up and down and is seated on the flange (9).

플랜지(9)의 저면에 부설된 회동트랜스(10)는 고정드럼(2)의 상면에 설치된 고정트랜스(11)와 연결되며 고정드럼(2)의 중앙에는 샤프트(7)가 돌출되고 베어링(16) (16')이 상하로 설치되었으며 하부에는 회동용 모터 (12)와 결합 설치한 것에 있어서, 고정 드럼(2)의 저면에 중계기판(5)을 부착하고 중계기판(5)의 일측 상면에 신호 전달 콘넥터(13)을 설치하여 고정드럼(2)에 뚫려 있는 통공(2a)을 통해 신호선(14)으로 신호전달 콘넥터 (13)에 연결한 다음 고정 스크류(17)를 고정 드럼(2)에 체결한다.The rotating transformer 10 attached to the bottom of the flange 9 is connected to the fixed transformer 11 installed on the upper surface of the fixed drum 2, and the shaft 7 protrudes from the center of the fixed drum 2, and the bearing 16 16 'is installed up and down, and the lower part is combined with the rotational motor 12, and the relay board 5 is attached to the bottom of the fixed drum 2, and the upper surface of one side of the relay board 5 is mounted. Install the signal transmission connector 13 and connect the signal transmission connector 13 to the signal transmission connector 13 through the through hole 2a which is drilled in the fixed drum 2, and then attach the fixing screw 17 to the fixing drum 2 Tighten.

그리고 환형홈(6c)와모양의 홈(6a)에 구멍(6b)이 뚫려있는 실드케이스(6)를 중개기판(5)에 형성되있는 고정구멍 (5a) (5a')을 통하여 스크류(15)로 고정드럼 (2)에 결합시킨다.And the annular groove 6c A shield case 6 having a hole 6b formed in the groove 6a of the shape is connected to the fixed drum 2 with a screw 15 through fixing holes 5a and 5a 'formed in the intermediate substrate 5. Combine.

이러한 구성으로 이루어진 본 고안의 동작은 헤드(3)(3')에서 감지된 신호가 고정 트랜스(11)까지 연결되어 신호전달콘넥터(13)에 전달될 때 고정 드럼(2)의 통공(2a)에 설치된 신호선(14)으로 중계기판(5)까지 연결되어 신호전달콘넥터 (13)에 전달되는 신호전달체계를 이루는 것이다. 그러므로 본 고안은 고정 드럼 (2)의 하부에서 신호전달용 기판이(5)직접 연결 방식으로 설치되고 실드케이스(6)로 외부의 전기적인 잡음을 차단함으로써 외부의 전기적인 잡음에 영향을 받지 않아 양질의 화면을 재생할 수 있고 또한 종래의 고정 드럼 측면에 부착되던 홀더가 배제됨으로 헤드 조립체의 부피가 훨씬 작아져 제품의 소형, 경량화와 함께 제조 원가를 절감하면서 생산성을 크게 향상시킬 수 있는 효과가 있다.The operation of the present invention made of this configuration is the through hole (2a) of the fixed drum (2) when the signal sensed in the head (3) (3 ') is connected to the fixed transformer 11 is transmitted to the signal transmission connector (13) It is connected to the relay board 5 by the signal line 14 installed in the to form a signal transmission system that is transmitted to the signal transmission connector (13). Therefore, the present invention is not affected by the external electrical noise by installing the signal transmission board at the lower part of the fixed drum (2) by direct connection and blocking the external electrical noise with the shield case (6). By reproducing a good quality screen and eliminating the holder attached to the side of the conventional fixed drum, the volume of the head assembly is much smaller, thereby reducing the manufacturing cost and reducing the manufacturing cost, thereby greatly improving productivity. .
