본 고안은 RF신호 수신 안테나 보오드에 있어서, 각기 상이한 2개의 RF신호를 쌍극성 릴레이를 제어하여 하나의 RF신호를 선택할 수 있도록한 2개의 RF신호 선택회로에 관한 것이다.The present invention relates to two RF signal selection circuits in which two different RF signals can be selected by controlling a bipolar relay in an RF signal receiving antenna board.

종래의 RF신호를 수신하는 기기에 있어서 신호 입력 잭은 하나만 설치되어 있는 관계로 2개의 상이한 RF신호로 선택하여 수신하기 위해서는 하나의 RF신호 입력 잭에 인가되는 RF신호 라인을 수동적으로 선택해 주어야만 하였다.In the conventional apparatus for receiving an RF signal, since only one signal input jack is installed, an RF signal line applied to one RF signal input jack has to be manually selected in order to select and receive two different RF signals.

즉 RF신호 수신 기기에서 RF신호 입력 잭이 하나만 설치되므로 각각의 RF신호를 선택하기 위해서는 기기의 RF신호 입력 잭에 인가되는 RF신호 라인을 수동으로 선택해 주어야만 하는 불편이 있었다.That is, since only one RF signal input jack is installed in the RF signal receiving device, it is inconvenient to manually select an RF signal line applied to the RF signal input jack of the device in order to select each RF signal.

본 고안은 이와같은 점을 감안하여 하나의 안테나 보오드로 2개의 상이한 RF신호중 하나를 선택하여 RF신호 입력 잭에 인가시키도록 한 것으로써 안테나 보오드에서 쌍극성 릴레이의 구동을 제어하여 2개의 상이한 RF신호중 하나의 RF신호를 선택하는 것이다.In view of the above, the present invention is to select one of two different RF signals with one antenna board and apply it to the RF signal input jack. It is to select one RF signal.

이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

입력단자(I1)에 인가된 전원(B+)은 콘덴서(C1)을 통하여 역기전류 제한용 다이오드(D1)가 접속된 쌍극성 릴레이단(1)의 릴레이 코일(L)에 인가된후 선택 전원(B+s)이 인가되지 않으면 콘덴서(C2)에 접속된 입력단자(I2)에 인가되며 이때 쌍극성 릴레이단(1)의 릴레이 스위치(a)가 '온'되어 안테나단자(ANT1)의 RF신호가 선택되어 튜우너 단에 인가되게 구성하고 또한 선택전원(B+s)이 인가될때 쌍극성 릴레이단의 릴레이 코일(L)에는 전류가 흐르지 못하여 릴레이 스위치(a)는 '오프'되면서 릴레이 스위치(b)가 '온'되므로 안테나단자(ANT2)에 인가된 RF신호는 튜너단에 인가되어 선택된 정보는 셋트에 출력되게 구성한 것이다.The power supply B + applied to the input terminal I 1 is applied to the relay coil L of the bipolar relay terminal 1 to which the countercurrent limiting diode D 1 is connected through the capacitor C 1 . If the selected power source (B + s) is not applied, it is applied to the input terminal (I 2 ) connected to the condenser (C 2 ), and the relay switch (a) of the bipolar relay terminal (1) is 'on' and the antenna terminal The RF signal of (ANT 1 ) is selected and configured to be applied to the tuner stage, and when the selected power source B + s is applied, no current flows to the relay coil L of the bipolar relay stage. Since the relay switch b is 'on' while being 'off', the RF signal applied to the antenna terminal ANT 2 is applied to the tuner terminal so that the selected information is output to the set.

이때 선택전원(B+s)은 안테나단자(ANT2)에 입력된 신호를 선택할때 공급하는 전원이고 입력단자(I1)에는 전원(B+)이 항시 인가되어 있어 안테나단자(ANT1)의 RF신호를 평상시 선택하게 되고 쌍극성 릴레이단(1)의 릴레이 스위치(a)(b)는 상반된 스위칭을 구성한 것이다.At this time, the selection power (B + s) is the power supplied when the signal input to the antenna terminal (ANT 2 ) is selected, and the power supply (B + ) is always applied to the input terminal (I 1 ) of the antenna terminal (ANT 1 ) The RF signal is normally selected and the relay switches (a) and (b) of the bipolar relay stage 1 constitute opposite switching.

따라서 하나의 안테나 보오드(BOARD)에 상이한 RF신호를 수신하여 선택전원(B+s)에 의해 콘트롤 되는 쌍극성 릴레이단(1)으로 RF신호를 선택하게 되는 것이다.Therefore, by receiving a different RF signal in one antenna board (BOARD) is to select the RF signal to the bipolar relay stage (1) controlled by the selection power source (B + s).

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

입력단자(I1)에 인가되는 전원(B+)는 셋트가 구동될때 항상 쌍극성 릴레이단(1)의 릴레이 코일(L)에 항시 인가되어 있으며 이때 선택전원(B+s)이 입력단자(I2)에 인가되지 않을 경우는 입력단자(I1)에 인가되어 있는 전원(B+)은 쌍극성 릴레이단(1)의 릴레이 코일(L)을 통하여 입력단자(I2)로 흐르게 되며 릴레이 스위치(a)가 '온'되며 릴레이 스위치(b)는 상반된 스위칭 작용으로 '오프'되어 안테나단자(ANT1)에 인가된 RF신호가 릴레이 스위치(a)를 통하여 튜우너단에 출력되어 안테나단자(ANT1)에 인가된 RF신호 정보는 세트에 나타나게 되는 것이다.The power source B + applied to the input terminal I 1 is always applied to the relay coil L of the bipolar relay terminal 1 when the set is driven, and the selected power source B + s is applied to the input terminal ( I 2) if the not is the flow to the input terminal (I 1), the power (B +) is a bipolar relay stage (1) an input terminal (I 2) through the relay coil (L) of which is applied to and relay The switch a is 'on' and the relay switch b is 'off' due to the opposite switching action, so that the RF signal applied to the antenna terminal ANT 1 is output to the tuner terminal through the relay switch a so that the antenna terminal ( RF signal information applied to ANT 1 ) is to appear in the set.

또한 전원(B+)과 거의 같은 레벨의 선택전원(B+s)이 입력단자(I2)에 인가될때는 쌍극성 릴레이단(1)의 릴레이 코일(L)에는 전류가 흐르지 않게 되어 릴레이 스위치(b)가 '온'이되며 릴레이 스위치(a)는 상반된 스위칭 작용으로 '오프'되므로 튜우너단에는 안테나단자(ANT2)에 인가된 상이한 RF신호가 릴레이 스위치(b)을 통하여 인가되므로써 셋트에 출력되는 것이다.In addition, the choice of substantially the same level as the power source (B +) power supply (B + s) is an input terminal (I 2) is applied when the pair of the relay coil (L) of the polarized relay stage (1) There is no current flow through the relay switch to (b) is 'on' and the relay switch (a) is 'off' due to the opposite switching action, so the different RF signals applied to the antenna terminal (ANT 2 ) are applied to the tuner stage through the relay switch (b). Is the output.

이상에서와 같이 본 고안은 상이한 RF신호를 수신하기 위해 별기의 안테나 단자를 설치하던 것을 하나의 안테나 보오드(Board)에 인가하여 전원에 의하여 제어되는 쌍극성 릴레이단으로 하나의 RF신호를 선택하도록 함으로써 셋트의 RF신호를 자동적으로 선택할수 있는 효과가 있는 것이다.As described above, the present invention applies a single antenna board to install a separate antenna terminal in order to receive different RF signals, so that one RF signal is selected as a bipolar relay stage controlled by a power source. The effect is to automatically select a set of RF signals.
