Alternatively, the video head or audio head of the DA reads the video signal or the audio signal recorded on the magnetic tape when the head drum is rotated, and the read signal is transferred to the circuit controller through the translator and the transmitter built into the head drum. To pass. The image or audio is reproduced in the above-described process by V-Cal or DieT, and the recording is performed in the reverse process.

상기한 바와같이 브이씨알과 디에이티등의 자기기록재생기용 헤드드럼에서 헤드와 트랜스로우터간의 신호를 전달하기 위한 신호연결장치는 종래에도 여러가지 알려지고 있으나, 구성이 복잡하거나 조립성이 양호하지 못한 결함이 있었다.As described above, a signal connecting device for transmitting a signal between the head and the translator in a head drum for magnetic recording and reproducing devices such as BC-D and DET has been known in the art, but it is a complicated configuration or a poor assembly. There was this.

본 고안은 자기기록재생기의 헤드드럼에서 비디오헤드 또는 오디오헤드등의 헤드와 트랜스로우터 사이에 신호를 연결하기 위한 신호연결장치로서 신호연결의 신뢰성을 유지하면서 헤드드럼의 조립성을 향상시킬 수 있도록 한 것인 바, 이하 이러한 본 고안을 첨부한 도면에 실시예를 들어 상세히 설명하면 다음과 같다.The present invention is a signal connection device for connecting a signal between a head of a magnetic recorder, such as a video head or an audio head and a translator, so that the assembly of the head drum can be improved while maintaining the reliability of the signal connection. It will be described below in detail with reference to the embodiment to the accompanying drawings of the present invention as follows.

제1도 내지 제4도에 도시한 바와같이, 하부고정드럼(1)에 회전축(2)이 상하부베어링(3) (4)을 개재하여 결합하고, 회전축(2)의 상부에 플랜지(5)가 압입됨과 아울러 그 플랜지(5)에는 복수개의 헤드(6)가 하면에 고정된 상부회전드럼(7)이 고정되며, 상기 하부고정드럼(1)과 플랜지(5)의 하단부에는 트랜스스테이터(8)와 트랜스로우터(9)가 서로 대향되게 각각 고정된 것에 있어서, 상기 트랜스로우터(9)의 주연부에 돌환부(9a)를 형성하여 그 내주면에 도전접촉면(10) (11)을 형성하고, 트랜스로우터(9)의 하부에 권회되는 코일(도시하지 않음)의 양단부(17) (17′)을 연결하는 한편, 헤드(6)의 하면에 부착된 인쇄회로기판(14)에는 상기 도전접촉면(10) (11)과 일단부가 각각 접촉되는 탄성신호연결편(12) (13)의 타단부를 연결하여서 된 것이다.As shown in FIGS. 1 to 4, the rotating shaft 2 is coupled to the lower fixed drum 1 via the upper and lower bearings 3 and 4, and the flange 5 is disposed on the upper portion of the rotating shaft 2. In addition, the upper rotary drum 7 fixed to the lower surface of the plurality of heads 6 is fixed to the flange 5, and the lower stationary drum 1 and the lower end of the flange 5 are fixed to the transstater 8. ) And the translator 9 are fixed so as to face each other, the projections 9a are formed at the periphery of the translator 9 to form conductive contact surfaces 10 and 11 on the inner circumferential surface thereof. Both ends 17 (17 ') of a coil (not shown) wound around the lower part of the rotor 9 are connected, while the conductive contact surface 10 is attached to the printed circuit board 14 attached to the lower surface of the head 6. 11) and the other end of the elastic signal connecting pieces 12 and 13 in which one end thereof contacts each other.

상기 신호연결편(12) (13)은 몸체(35)일단부에 도전접촉면(10) (11)과 접촉되는 접촉부 (15a)가 형성되고, 타단부에는 인쇄회로기판(14)과 연결되는 연결부 (15b)가 형성되어 있다.The signal connection pieces 12 and 13 have a contact portion 15a formed at one end of the body 35 to be in contact with the conductive contact surfaces 10 and 11, and a connection portion connected to the printed circuit board 14 at the other end thereof. 15b) is formed.

상기 신호연결편(12) (13)의 몸체(15)는 탄성을 가지는 금속판으로 가공되는 것이나, 몸체(15)를 합성수지로 만들고 몸체(15)의 일면에는 전도물을 코팅하여 전도막을 형성한 것도 이용할 수 있다.The body 15 of the signal connecting piece 12, 13 is processed by a metal plate having elasticity, or the body 15 is made of synthetic resin, and one surface of the body 15 is coated with a conductive material to form a conductive film. Can be.

상기 신호연결편(12) (13)은 제1도 및 제2도와 같이 접촉부(15a)가 트랜스로우터(9)의 도전접촉면(10) (11)과 약간 떨어져 있도록 조립되며, 이에따라 본 고안은 헤드드럼을 조립하는 때 신호연결편(12) (13)의 접촉부(15a)가 트랜스로우터(9)의 돌환부(9a) 및 그외 다른 부분과 간섭되지 않도록 조립할 수 있으므로, 조립을 쉽게할 수 있다.The signal connecting pieces 12 and 13 are assembled such that the contact portions 15a are slightly separated from the conductive contact surfaces 10 and 11 of the translator 9, as shown in FIGS. 1 and 2, and accordingly, the present invention provides a head drum. Since the contact portions 15a of the signal connecting pieces 12 and 13 can be assembled so as not to interfere with the projections 9a and other portions of the translator 9, the assembly can be easily performed.

제1도 및 제2도와 같이 조립된 헤드드럼의 상부회전드럼(7)를 회전시키면 상부회전드럼(7)과 함께 헤드(6) 및 신호연결편(12) (13)이 회전하고 이에따라 신호연결편(12)(13)이 원심력에 의하여 변형되면서 퍼져 접촉부(15a)가 도전접촉면 (10)(11)과 접촉되어 헤드(6)와 트랜스로우터(9) 사이에 신호를 연결할 수 있게된다.Rotating the upper rotary drum 7 of the head drum assembled as shown in FIGS. 1 and 2 rotates the head 6 and the signal connecting pieces 12 and 13 together with the upper rotating drum 7 and accordingly the signal connecting piece ( 12) (13) is deformed by centrifugal force so that the contact portion 15a comes into contact with the conductive contact surfaces 10 and 11 so as to connect a signal between the head 6 and the translator 9.

상기 신호연결편(12) (13)의 접촉부(15a)는 상부회전드럼(7)회전시 원심력을 받아 트랜스로우터(9)의 도전접촉면(10) (11)에 접촉되는 구조이므로 상기 신호연결편(12) (13)의 접촉부(15a)에는 강한 원심력이 작용할 수 있도록 중량체(16)를 구비하는 것이 바람직하다.Since the contact portion 15a of the signal connection piece 12 and 13 is in contact with the conductive contact surfaces 10 and 11 of the translator 9 under centrifugal force when the upper rotary drum 7 rotates, the signal connection piece 12 It is preferable to provide the weight body 16 in the contact part 15a of (13) so that a strong centrifugal force may act.

상기 중량체(16)는 접촉부(15a)를 원호형으로 형성하고 그 내측에 접합하는 것이나, 이에 한정될 필요는 없다.The weight body 16 is to form a contact portion (15a) in an arc shape and to join the inside, but is not limited thereto.

상기 트랜스로우터(9)의 돌환부(9a)내주면에 형성되는 도전접촉면(10) (11)은 제4도와 같이 수평으로 소정간격을 두고 형성하고, 신호연결편(12) (13)의 각 접촉부(15a)도 수평으로 배치하여 접촉되도록 하는 것이 좋으나, 배치구조를 여러가지로 변경할 수도 있다.The conductive contact surfaces 10 and 11 formed on the inner circumferential surface of the protrusion 9a of the translator 9 are formed at a predetermined interval horizontally as shown in FIG. 4, and each contact portion of the signal connecting pieces 12 and 13 ( 15a) is also preferably arranged horizontally so as to be in contact, but the arrangement structure may be changed in various ways.

상기한 바와같이된 본 고안은 신호연결편(12) (13)의 접촉부(15a)와 트랜스로우터(9)의 도전접촉면(10) (11)이 서로 소정간격 만큼 떨어지게 조립되는 것이므로 조립시 간섭이 없어 조립성이 양호하며, 조립후 회전동작시에는 신호연결편(12) (13)이 원심력에 의하여 휘어지면서 접촉부(15a)가 도전접촉면(10) (11)에 양호하게 접촉되므로 헤드(16)와 트랜스로우터(9)사이의 신호연결에도 무리가 없다.The present invention as described above is assembled so that the contact portion (15a) of the signal connecting piece (12) (13) and the conductive contact surface (10) (11) of the translator (9) apart from each other by a predetermined interval there is no interference during assembly The assembly is good, and during the rotation operation after assembly, the signal connecting pieces 12 and 13 are bent by the centrifugal force and the contact portion 15a is in good contact with the conductive contact surfaces 10 and 11, so that the head 16 and the transformer There is no problem in the signal connection between the rotors 9.

따라서 본 고안의 장치는 헤드드럼의 신뢰성을 유지하면서 조립성을 향상시키는 이점이 있다.Therefore, the device of the present invention has the advantage of improving the assembly while maintaining the reliability of the head drum.
