본 고안은 브이씨알 또는 디지탈 오디오 테이프 레코더(이하, 디에이티라 칭함)의 해드드럼조립체의 신호연결장치에 관한 것으로, 특히 헤드드럼조립체에 인접하여 헤드의 신호를 전달받는 주회로기판을 설치함으로써 구성을 간소화시키면서 노이즈 현상을 감소시키고, 조립공정을 간소화시킬 수 있게 한 헤드드럼조립체의 신호연결 장치에 관한 것이다.The present invention relates to a signal connection device of a head drum assembly of a BC-AL or digital audio tape recorder (hereinafter referred to as "DAT-TI"), and particularly, by installing a main circuit board receiving a head signal adjacent to the head drum assembly. The present invention relates to a signal connection device of a head drum assembly which can reduce noise while simplifying an assembly process.
종래의 브이씨알 또는 디에이티의 헤드드럼조립체는 제1도 및 제2도에 도시한 바와 같이, 하부실린더(1)에 상. 하부베어링(2)(2')을 압입고정한 후, 고정자(3)를 접착고정하고, 신호연결을 위한 중계기판(4)을 하부실린더(1)의 절결홈(1a)을 통하여 삽입하여 하부실린더(1)의 저면에 나사(5)로 고정하며, 상기 고정자(3)의 신호선(6)을 중계기판(4)의 일측 동박면부위(a)에 납땜 고정한 다음 중계기판(4)의 타측 동박면부위(b)에 신호선(7)을 납땜 고정하는 한편 회전축(9)에 플랜지(10)을 압입고정한 다음 그 플랜지(10)의 하면에 회전자(11)를 고정하며, 이와 같이된 회전축(9)을 하부 실린더(1)에 끼워넣되, 고정자(3)와 회전자(11)의 사이에는 일정 갭(gap)이 유지되게 한 후, 회전축(9)의 하측 부위에는 부싱(12)을 삽입하여 상. 하부베어링(2)(2')을 예압함과 아울러, 상부실린더(13)의 저면에는 수개의 헤드(14)를 나사(15)로 고정하며, 그 상부실린더(13)를 회전축(9)에 삽입한 후, 나사(16)로 플랜지(10)에 체결함으로써 조립이 완료된다.The head drum assembly of a conventional BC or DA is mounted on the lower cylinder 1, as shown in FIGS. 1 and 2. After press-fitting and fixing the lower bearings (2) and (2 '), the stator (3) is adhesively fixed, and the relay board (4) for signal connection is inserted through the notch groove (1a) of the lower cylinder (1) to lower the cylinder. The bottom of (1) is fixed with screws (5), and the signal line (6) of the stator (3) is soldered and fixed to one copper foil surface portion (a) of the relay board (4), and then the other copper foil of the relay board (4). While soldering and fixing the signal line 7 to the surface portion b, the flange 10 is press-fitted to the rotating shaft 9, and then the rotor 11 is fixed to the lower surface of the flange 10, and thus the rotating shaft ( 9) is inserted into the lower cylinder (1), but a gap is maintained between the stator (3) and the rotor (11), and then the bushing (12) is inserted into the lower portion of the rotating shaft (9) By award. While preloading the lower bearings (2) and (2 '), several heads (14) are fixed to the bottom of the upper cylinder (13) with screws (15), and the upper cylinder (13) is attached to the rotating shaft (9). After insertion, assembly is completed by fastening to the flange 10 with screws 16.
또한, 상기 신호선(7)은 일정길이로 연상되어 그 단부가 헤드드럼조립체가 설치되는 데크의 밖에 일정거리를 두고 설치된 콘넥터(8)에 연결되며, 상기 콘넥터(8)는 주회로기판과 연결되고, 상기 콘넥터(8)와 주회로기판은 미세한 헤드(2)의 신호를 노이즈(noise)로 부터 보호하기 위하여 실드케이스로 감싸게 된다.In addition, the signal line 7 is elongated in a predetermined length and its end is connected to the connector 8 provided at a certain distance outside the deck on which the head drum assembly is installed, and the connector 8 is connected to the main circuit board. The connector 8 and the main circuit board are wrapped in a shield case to protect the signal of the fine head 2 from noise.
그러나 상기한 바와 같은 종래 헤드드럼조립체는 납땜 부위의 과다 및 중계기판(4)의 외부노출로 미세한 신호 전달에 노이즈가 발생되며, 신호선(7)을 길게 하여야만 주회로기판에 연결할 수 있으므로 노이즈의 원인 및 저항의 증가로 여러 문제점을 내포하고 있을 뿐만아니라 신호선(7)과 콘넥터(15)의 연결작업 불량으로 인하여 신호중계에 많은 난점이 있었다.However, in the conventional head drum assembly as described above, noise is generated in a small signal transmission due to excessive soldering and external exposure of the relay board 4, and the signal line 7 can be connected to the main circuit board only because the signal line 7 is lengthened. In addition, there are many problems in signal relay due to poor connection work between the signal line 7 and the connector 15 as well as the problems caused by the increase in resistance.
또한, 신호선(7), 콘넥터(8)등 여러 부품이 요구되어 구성이 복잡하며, 하부실린더(1) 및 중계기판(4)에 나사공을 각각 천공하여 중계기판(4)을 나사(5)로 체결시켜야 하는 등 조립공정이 용이하지 못한 문제점이 있었다.In addition, a complicated configuration due to various components such as a signal line 7 and a connector 8 is required, and the relay board 4 is screwed by drilling a screw hole in the lower cylinder 1 and the relay board 4, respectively. There was a problem that the assembly process is not easy, such as to be fastened to.
따라서 본 고안은 상기한 바와 같은 종래의 문제점을 해소하기 위하여 고정자의 하면에 플렉시블와이어의 동박면에 다수개 플레이트단자가 부착된 플렉시블와이어조립체를 부착고정하고, 헤드드럼조립체가 설치되는 데크의 일측에 주회로기판을 갖는 실드케이스를 고정하여 상기 주회로기판의 동박면에 플렉시블와이어조립체의 플레이트단자를 직접 납땜 고정함으로써 구성을 간소화시키면서 노이즈 현상을 감소시킨는 동시에 조립공정을 간소화시킬 수 있도록 구성한 것인 바, 이를 첨부도면에 의하여 설명하면 다음과 같다.Therefore, the present invention is fixed to the flexible wire assembly having a plurality of plate terminals attached to the copper foil surface of the flexible wire on the lower surface of the stator in order to solve the conventional problems as described above, on one side of the deck on which the head drum assembly is installed The shield case having the main circuit board is fixed to solder the plate terminal of the flexible wire assembly directly to the copper foil surface of the main circuit board to simplify the configuration while reducing the noise phenomenon and simplify the assembly process. This will be described with reference to the accompanying drawings.

A plurality of plate terminals 18 are attached to the copper foil portion c formed at the lower end of the wire 17, and the flexible wire assembly 19 on which the signal line 6 of the stator 3 is soldered and fixed to the other side is stator. (3) attached to the lower surface of the lower cylinder (1) by fixing the stator (3) to the bottom surface of the lower cylinder (1), press-fit the flange (10) to the rotating shaft (9), and then to the lower surface of the flange (10) The former (11) is fixed, the rotary shaft (9) is inserted into the lower cylinder (1), and the bushing (12) is inserted into the lower portion of the rotary shaft (9). The lower bearings (2) and (2 ') are preloaded, and the upper cylinder (13) in which several heads (14) are fixed with screws (15) is inserted into the rotating shaft (9) and the flanges (10) with screws (16). Assembly is completed by fastening to the upper part, and as shown in FIG. 6, a shield case 23 having a main circuit board 22 therein is provided at the distal end of the deck 21 on which the head drum assembly 20 is installed. The copper foil portion d of the signal connection pin c is exposed to the shield case 23 corresponding to the plate terminal 18 of the flexible wire assembly 19 by fixing with screws 24 and 24 '. The structure in which the plate terminal 18 is soldered and fixed to the portion d, in which 1a shows a cutout groove of the lower cylinder 1.
이와 같이 구성된 본 고안은 헤드(14)의 신호를 중계하는 신호 연결기판이 아닌 헤드(14)의 신호를 직접 받는 주회로기판(22)을 헤드드럼조립체(20)가 설치되는 데크(21)에 설치하여 그 헤드드럼조립체(20)와 주회로기판(22)의 사이를 최근접으로 유지시킴으로써 헤드(14)의 신호를 주회로기판(22)에 간단히 전달할 수 있게 된다.According to the present invention configured as described above, the main circuit board 22 directly receiving the signal of the head 14, rather than the signal connection board relaying the signal of the head 14, is mounted on the deck 21 in which the head drum assembly 20 is installed. By installing and maintaining the head drum assembly 20 and the main circuit board 22 closest to each other, the signal of the head 14 can be easily transmitted to the main circuit board 22.
따라서 본 고안은 종래와 같은 신호선, 콘넥터 등의 부품을 사용하지 않게되므로 구성이 간소화되는 동시에, 종래의 경우와 같이 헤드드럼조립체와 주회로기판의 거리가 멀기 때문에 발생되는 노이즈 현상을 대폭 감소시킬 수 있으며, 작업공정을 간소화시켜 생산성을 향샹시킬 수 있는 등의 효과가 있다.Therefore, the present invention does not use the components such as signal lines and connectors as in the prior art, which simplifies the configuration and greatly reduces noise caused by the distance between the head drum assembly and the main circuit board as in the conventional case. In addition, there is an effect such as improving the productivity by simplifying the work process.
