1, 1', 2, 2' : 채널 3 : 홈1, 1 ', 2, 2': Channel 3: Home

본 고안은 로터리 트랜스에 관한 것으로서, 보다 상세하게는 동일 크기에 보다 많은 채널을 형성할 수 있는 로터리 트랜스에 관한 것이다.The present invention relates to a rotary transformer, and more particularly, to a rotary transformer capable of forming more channels in the same size.

일반적으로, 로터리 트랜스는 VTR(Video Tape Recoder)에서 테이프의 신호를 재생 회로에 전달하게 되는 역할을 하게 된다.In general, a rotary transformer serves to transmit a signal of a tape to a reproduction circuit in a video tape recorder (VTR).

즉, 테이프와 직접 접촉하게 되는 VTR의 헤드 드럼 어셈블리에 설치되는 바, 상기한 헤드 드럼 어셈블리는 어퍼, 로워 드럼이 로터리 트랜스를 개재한 상태로 조립되고, 상기한 어퍼 드럼은 테이프와 접촉한 상태로 고속 회전하고 어퍼 드럼은 정지된 상태가 된다.That is, it is installed in the head drum assembly of the VTR which is in direct contact with the tape, wherein the head drum assembly is assembled with the upper and lower drums through the rotary transformer, and the upper drum is in contact with the tape. It rotates at high speed and the upper drum is stopped.

물론, 상기한 어퍼 드럼에는 실질적으로 신호를 읽게 되는 다수의 헤드가 설치되어 있다.Of course, the upper drum is provided with a plurality of heads for reading a signal substantially.

여기서, 상기한 헤드 드럼 어셈블리에 조립된 로터리 트랜스는 2개가 한조로 구성되어 일측은 어퍼 드럼과 같이 회전하게 되고, 타측은 로워 드럼에 조립되어 정지되어 있게 된다.Here, the rotary transformer assembled to the head drum assembly is composed of two sets so that one side rotates like the upper drum, and the other side is assembled and stopped on the lower drum.

상기한 바와 같은 로터리 트랜스는 회전되는 헤드에서 읽은 신호를 정지되어 있는 로워 드럼에 전달하기 위해 사용되는 바, 이는 제2도에 도시된 바와 같이 회전축(50)과, 상기 회전축(50)에 고정되어 있는 어퍼 코어(51)와, 상기한 어퍼 코어(51)와 대향되도록 고정 설치되어 있는 로워 코어(52)로 구성되어 있다.The rotary transformer as described above is used to transmit a signal read from the rotating head to the stationary lower drum, which is fixed to the rotating shaft 50 and the rotating shaft 50 as shown in FIG. It consists of the upper core 51 which exists, and the lower core 52 fixedly installed so as to oppose the upper core 51 mentioned above.

특히, 상기한 어퍼, 로워 코어(51, 52)에는 서로 대향되도록 다수의 홈(53)이 형성되어 있고, 상기한 홈(53)에는 쇼트링(54)을 개재한 상태로 다수의 채널(55, 55', 56, 56')이 교번 형성되어 있다.In particular, the upper and lower cores 51 and 52 are provided with a plurality of grooves 53 so as to face each other, and the grooves 53 are provided with a plurality of channels 55 with a short ring 54 interposed therebetween. , 55 ', 56, 56') are alternately formed.

상기한 바와 같은 로터리 트랜스는 헤드(미 도시)에서 읽은 신호가 어퍼 코어(51)에 형성된 다수의 채널(55, 55')에 전달되면 상기한 채널(55, 55')에서 자장이 발생된다.In the rotary transformer as described above, when a signal read from a head (not shown) is transmitted to a plurality of channels 55 and 55 'formed in the upper core 51, the magnetic field is generated in the channels 55 and 55'.

어퍼 코어(51)의 채널(55, 55')에서 발생된 자장은 이와 근접 대향되도록 로워 코어(52)에 형성된 채널(56, 56')에 전달되고 이는 로워 코어(52)에 연결된 재생 회로에 전달되어 신호가 음성 및 화상으로 재생되는 것이다.The magnetic field generated in the channels 55, 55 ′ of the upper core 51 is transmitted to the channels 56, 56 ′ formed in the lower core 52 so as to face in close proximity thereto, which is transmitted to the regeneration circuit connected to the lower core 52. The signal is transmitted to reproduce the voice and the image.

여기서, 상기한 다수의 채널(55, 55', 56, 56')은 자장을 통해 신호를 전달받기 때문에 인접 채널(55', 56')에 자장이 미치게 되면 신호가 누설(Cross Talk)되는 바, 이를 방지하기 위하여 각 채널(55, 55', 56, 56')간에는 쇼트링(54)이 설치되어 있게 된다.Here, since the plurality of channels 55, 55 ′, 56, 56 ′ receive a signal through the magnetic field, when the magnetic field extends to the adjacent channels 55 ′, 56 ′, the signal is leaked (cross talk). In order to prevent this, the short ring 54 is installed between each of the channels 55, 55 ′, 56, 56 ′.

즉, 어퍼, 로워 코어(51, 52)를 타고 인접 채널(55, 55', 56, 56')로 전달되는 신호가 쇼트링(54)으로 차단됨으로서 각 채널(55, 55', 56, 56')간의 누설을 방지하여 재생되는 음성 및 화상을 보다 선명하게 하는 것이다.That is, the signals transmitted to the adjacent channels 55, 55 ′, 56, and 56 ′ by the upper and lower cores 51 and 52 are blocked by the short ring 54, so that each channel 55, 55 ′, 56, 56 is blocked. It is to prevent the leakage between ') to make the reproduced voice and image more clear.

그러나, 상기한 바와 같이 어퍼, 로워 코어(51, 52)의 일측면 즉, 어퍼, 로워 코어(51, 52)의 대향면에 다수의 채널(55, 55', 56, 56')과 쇼트링(54)을 같이 설치함은 설치가 필수 불가결한 소트링에 의해 채널(55, 55', 56, 56')에 사용되는 면적이 감소되어 일정한 면적인 어퍼, 로워 코어(51, 52)의 다채널화가 어렵게 되는 문제점이 있다.However, as described above, a plurality of channels 55, 55 ′, 56, 56 ′ and short rings are formed on one side of the upper and lower cores 51 and 52, that is, the opposing surfaces of the upper and lower cores 51 and 52. (54) is installed together, the area used for the channels (55, 55 ', 56, 56') is reduced by the sort ring which is indispensable for installation, so that the upper and lower cores (51, 52) have a constant area. There is a problem that channelization becomes difficult.

따라서, 본 고안의 목적은 상기한 문제점을 해결하기 위한 것으로서, 동일한 면적의 코어에 보다 많은 채널과 쇼트링을 형성할 수 있도록 구성한 로터리 트랜스를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and to provide a rotary transformer configured to form more channels and short rings in a core having the same area.

상기한 목적을 실현하기 위하여 본 고안은 채널간의 간격을 단축시켜 동일 면적에 보다 많은 채널을 형성할 수 있도록 대향되어 있는 어퍼, 로워 코어의 배면에 각채널간의 사이에 위치되도록 호을 형성하여 구성함을 특징으로 한다.In order to realize the above object, the present invention is formed by forming an arc so as to be located between each channel on the back of the upper and lower cores facing each other so as to form more channels in the same area by shortening the distance between the channels. It features.

이하, 첨부 도면을 참조하여 본 고안의 상세한 일 실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, a detailed embodiment of the present invention will be described.

제1도는 본 고안에 따른 로터리 트랜스를 도시한 반단면도로서, 다수의 채널(1, 1', 2, 2')이 대향 형성되어 있는 어퍼, 로워 코어(51, 52)의 배면 즉, 대향되지 않은 면에 쇼트링(54)이 삽입되는 홈(3)이 형성되어 있다.FIG. 1 is a half sectional view showing a rotary transformer according to the present invention. The upper and lower cores 51 and 52 on which the plurality of channels 1, 1 ', 2, and 2' are formed facing each other, that is, are not opposed to each other. The groove 3 into which the short ring 54 is inserted is formed on the surface.

또한, 상기한 홈(3)은 각 채널(1, 1', 2, 2')의 사이에 위치하도록 형성됨과 아울러 채널(1, 1', 2, 2')과의 간격을 코어의 수평방향으로 주어진 거리를 D로, 상기 코어의 수직방향으로 주어진 거리를 D1으로 설정하여 어퍼, 로워 코어(51, 52)의 강도에 영향을 주지 않도록 하고, 상기한 홈(3)의 크기도 강도에 영향을 주지 않을 정도로 적절하게 설정되어 있다.In addition, the groove 3 is formed so as to be located between each channel (1, 1 ', 2, 2') and the interval with the channel (1, 1 ', 2, 2') in the horizontal direction of the core The distance given by D is set to D and the distance given in the vertical direction of the core to D1 so as not to affect the strength of the upper and lower cores 51 and 52, and the size of the groove 3 also affects the strength. It is set so that it does not give.

상기한 바와 같은 본 고안의 작용 효과를 설명하면 도시되지 않은 헤드 드럼 어셈블리에서 어퍼 드럼이 회전하게 되면 여기에 설치되어 있는 헤드가 테이프의 신호를 읽게 된다.Referring to the operation and effect of the present invention as described above, when the upper drum rotates in the head drum assembly (not shown), the head installed therein reads the signal of the tape.

헤드가 테이프의 신호를 읽게 되면 이와 연결된 어퍼 코어(51)의 각 채널(1, 1')로 신호가 전달되어 각 채널(1, 1')에서 자장 발생시키게 된다.When the head reads the signal of the tape, the signal is transmitted to each channel 1, 1 'of the upper core 51 connected thereto to generate a magnetic field in each channel 1, 1'.

상기한 채널(1, 1')에에서 발생된 자장은 이와 대향된 로워 코어(52)의 각 채널(2, 2')에 전달되는 바, 이때 상기한 자장은 코어(51, 52)를 타고 인접 채널(1, 1', 2, 2')로 전달되고 있는 어퍼, 로워 코어(51, 52)의 배면에 형성된 쇼트링(54)에 의해 차단된다.The magnetic field generated in the channels (1, 1 ') is transmitted to the respective channels (2, 2') of the lower core (52) opposed to the magnetic field, which is carried on the core (51, 52) It is blocked by the short ring 54 formed on the back of upper and lower cores 51 and 52 which are being transmitted to the adjacent channels 1, 1 ', 2 and 2'.

여기서, 상기한 쇼트링(54)은 채널(1, 1', 2, 2')이 형성된 면이 아닌 배면에 형성되기 때문에 각 채널(1, 1', 2, 2')간의 거리가 종래보다 약 1.5~2배정도 단축되고 상기한 각 채널(1, 1', 2, 2')의 사이 배면에 쇼트링(54)이 형성된다.Here, since the short ring 54 is formed on the rear surface of the channel 1, 1 ′, 2, and 2 ′ rather than the surface on which the channels 1, 1 ′, 2, and 2 ′ are formed, the distance between each channel 1, 1 ′, 2, 2 ′ is greater than that of the conventional art. It is shortened by about 1.5 to 2 times and a short ring 54 is formed on the back surface between each of the channels 1, 1 ', 2 and 2'.

물론, 상기한 쇼트링(54)을 홈(3)에 삽입하지 않고 홈(3)만 형성하여도 누설 자속의 차단 효과는 있지만 그 효과가 미미하게 된다.Of course, if only the groove 3 is formed without inserting the above-mentioned short ring 54 into the groove 3, there is an effect of blocking the leakage magnetic flux, but the effect is insignificant.

상기한 바와 같이 각 채널(1, 1', 2, 2')간의 간격이 종래보다 약 1.5~2배정도 단축되면 동일한 면적이 어퍼, 로워 코어(51, 52)에 보다 많은 채널(1, 1', 2, 2') 형성이 용이하게 되어 다채널화되는 VTR에 대해 드럼 어셈블리의 크기를 변경시키지 않아도 대응 가능하게 되는 것이다.As described above, when the distance between each channel (1, 1 ', 2, 2') is reduced by about 1.5 to 2 times as compared with the conventional one, the same area is upper, and more channels (1, 1 ') are provided in the lower cores (51, 52). , 2, 2 ') can be easily formed without changing the size of the drum assembly for the multi-channel VTR.

이상과 같이 본 고안은 쇼트링을 어퍼, 로워 코어가 대향되지 않은 배면에 형성함으로써 채널간 간격을 단축시켜 동일한 면적이 코어에 다채널화가 가능하게 되는 잇점이 있는 것이다.As described above, the present invention has an advantage in that the short ring is formed on the rear surface of the upper and lower cores which are not opposed to each other, thereby shortening the distance between the channels so that the same area can be multichanneled in the core.
