본 고안은 텔레비젼 튜너에 신호전원을 인가시켜 주도록 된 단자구조에 관한 것으로, 특히 콘덴서를 이용하여 신호전원단을 간단하게 바이패쓰 시켜줄 수 있도록 된 튜너의 바이패쓰형 단자구조에 관한 것이다.The present invention relates to a terminal structure for applying a signal power source to a television tuner, and more particularly, to a bypass type terminal structure of a tuner which allows a signal bypass stage to be simply bypassed.
텔레비젼 튜너에는 일반적으로 구동전원이나 밴드 선택전원 또는 AFT, AGC 전원등을 인가시켜 줄수 있도록 신호전원 단자가 다수 설치되어지게 되는데, 이러한 신호전원입력단자는 노이즈를 방지하고 안정된 신호전원이 인가될수 있도록 콘덴서를 사용하여 바이패쓰 시켜주 필요가 있다.In general, a TV tuner is provided with a plurality of signal power terminals to supply driving power, band selection power, or AFT or AGC power. These signal power input terminals are condenser to prevent noise and to provide stable signal power. It needs to be bypassed using.
이와같은 필요에 따라, 특히 고주파대역의 신호를 처리하도록 된 튜너에 있어서는, 피드쓰루콘덴서(feedthrough capacitor)를 사용하여 신호전원 입력단을 바이패쓰 시켜주게 되는데, 이러한 피드쓰루콘덴서는 가격이 매우 비싸기 때문에 튜너의 원가를 상승시키는 요인이 되었다.According to such a need, especially in a tuner designed to process signals in a high frequency band, a feedthrough capacitor is used to bypass the signal power input stage. Since the feedthrough capacitor is very expensive, the tuner is very expensive. It was a factor that raised the cost of
한편 상기와 같은 고가의 피드쓰루콘덴서를 사용하지 않고 신호전원단을 바이패쓰 시켜줄수 있도록 하기 위해서, 종래에도 베이크라이트와 같은 절연판을 사용하여 단자핀을 절연시켜준 다음 상기 단자핀과 전면 샤씨 사이에 바이패쓰용 콘덴서를 설치하여 신호 전원단을 바이패쓰 시켜주도록하는 방법을 사용해왔던 바, 이와같은 종래의 단자구조는 제3도에 도시되어 있다.On the other hand, in order to bypass the signal power supply terminal without using the expensive feedthrough capacitor as described above, insulate the terminal pin using an insulation plate such as bakelite, and then between the terminal pin and the front chassis The conventional terminal structure is shown in FIG. 3 by installing a bypass capacitor so as to bypass the signal power supply stage.
즉, 전면샤씨(11)에 베이클라이트 절연판(12)을 부착하여 상기 베이클라이트(12)를 통해 단자핀(13)이 관통되어 지고, 상기 단자핀(13)에는 PCB(도시되지 않음)상의 회로소자와 연결될수 있도록 땜납부(14)가 형성되어져 있는바, 상기 땜납부(14)에는 바이패쓰용 콘덴서가 설치되어 전면샤씨(11)나 PCB의 접지단에 연결되도록 함으로써 신호 전원단자핀(B)이 바이패쓰 되어지게 되는 것이다.That is, by attaching the bakelite insulating plate 12 to the front chassis 11, the terminal pin 13 is penetrated through the bakelite 12, and the terminal pin 13 has a circuit element on a PCB (not shown). The solder part 14 is formed to be connected to the bar. The solder part 14 is provided with a bypass capacitor to be connected to the front chassis 11 or the ground terminal of the PCB so that the signal power terminal pin B ) Will be bypassed.
그러나 이와 같은 구조에서는 콘덴서가 전면샤시(11)로 우회 연결되거나 PCB의 접지단까지 비교적 먼거리로 연결되어져야 하므로 바이패쓰의 효율이 떨어지게 되고, 이와같은 낮은 효율을 보상시켜주기 위한 쵸크코일을 별도 설치해 주어야 하는등 불편이 있었으며, 그에따라 PCB 및 튜너전체의 구조가 복잡해지고 그 크기가 커지게 되는 등의 문제점이 있었다.However, in such a structure, the capacitor must be bypassed to the front chassis 11 or connected to the ground terminal of the PCB at a relatively long distance, thereby reducing the efficiency of the bypass, and separately installing choke coils to compensate for such low efficiency. There was an inconvenience, such as to give, according to the structure of the PCB and the tuner as a whole becomes complicated and its size is increased.
이에 본 고안은 상기와 같은 종래의 튜너의 단자구조가 가지고 있는 문제점을 해결하게 위해서, 전면샤시의 관통공을 형성시킬때 전면샤시의 일부를 절곡시켜 베이클라이트 등으로 된 절연판을 관통하는 접지돌기를 형성시켜 줌으로써 단자핀과 전면샤시와의 바이패쓰가 용이하도록 할뿐만 아니라 별도의 쵸크코일을 사용할 필요없이 간단한 구조로 바이패쓰 효과를 얻을 수 있도록 된 튜너의 바이패쓰형 단자구조를 제공하는데 구 목적이 있다.In order to solve the problems of the conventional tuner terminal structure, the present invention forms a grounding protrusion penetrating an insulating plate made of bakelite by bending a part of the front chassis when forming the through hole of the front chassis. The purpose is to provide a bypass-type terminal structure of the tuner that allows the bypass between the terminal pin and the front chassis to be easily facilitated and the bypass effect can be obtained with a simple structure without the need for a separate choke coil. .
이하 본 고안의 구성 및 작용효과를 예시도면에 의거 상세히 설명하기로 한다.Hereinafter will be described in detail on the basis of the configuration and working effects of the present invention.
본 고안은 전면샤씨(1)의 관통공(2) 외주면에 접지돌기(3)를 절곡 형성시켜주고, 상기 전면샤씨(1)의 배면에는 핀구멍(4) 및 접지돌기(3)의 관통구멍(5)이 형성된 절연판(6)을 설치하며, 상기 절연판(6)의 핀구멍(4)에는 단자핀(7)을 삽통시켜주면서 상기 단자핀(7)과 접지돌기(3) 사이에는 바이패쓰용 콘덴서(8)를 설치시켜 준 구조로 되어 있다.The present invention forms a bending protrusion 3 on the outer circumferential surface of the through hole 2 of the front sash 1, and the pin hole 4 and the ground protrusion 3 are formed on the rear surface of the front sash 1. An insulating plate 6 having a through hole 5 is provided, and between the terminal pin 7 and the ground protrusion 3 while inserting the terminal pin 7 into the pin hole 4 of the insulating plate 6. It has a structure in which a bypass capacitor (8) is provided.

상기와 같은 구조를 갖는 본 고안은 단자핀(7)이 접지돌기(3)를 통해 근거리에서 전면샤씨(1)로 바이패쓰되어질 수 있으므로 바이패쓰 효율이 높고 별도의 쵸크코일을 사용할 필요가 없으며, 상기 절연판(6)으로는 베이클라이트판 등이 사용될 수 있고 상기 콘덴서(8)로는 디스크형 세라믹콘덴서가 적당하다.The present invention having the above structure has a high bypass efficiency and does not require a separate choke coil because the terminal pin 7 can be bypassed to the front chassis 1 at a short distance through the ground protrusion 3. As the insulating plate 6, a bakelite plate or the like may be used, and as the capacitor 8, a disc ceramic capacitor is suitable.
제1도는 본 고안에 따른 단자구조의 분리사시도로서 전면샤씨(1)에는 관통공(2)이 형성되면서 그 외주연에 절곡된 접지돌기(3)가 형성되어져 있고, 절연판(6)에는 상기 접지돌기(3)가 관통되어질 관통구멍(5)과 단자핀(7)이 삽통되어질 핀구멍(4)이 형성되어져 있으며, 상기 핀구멍(4)에는 단자핀(7)이 끼워지도록 되어 있다.1 is an exploded perspective view of the terminal structure according to the present invention, the through-shape (2) is formed in the front chassis (1) is formed with a ground projection (3) bent on the outer periphery, the insulating plate (6) A through hole 5 through which the ground protrusion 3 is to be penetrated and a pin hole 4 through which the terminal pin 7 is inserted are formed, and the terminal pin 7 is fitted into the pin hole 4.
상기와 같은 전면샤씨(1)와 절연판(6) 및 단자핀(7)이 결합되어질 경우 그 단면 형상은 제2도와 같이 도시되어질 수 있는바, 전면샤씨(1)의 접지돌기(3)는 절연판(6)의 관통구멍(5)을 관통하여 튜너의 내부로 돌출되어지게 되고, 단자핀(7)과 상기돌출된 접지돌기(3)에는 땝납부(9,9')가 각각 형성되어 바이패쓰용 콘덴서(8)를 연결시켜 줄 수 있게 된다.When the front chassis 1, the insulation plate 6 and the terminal pin 7 as described above are combined, the cross-sectional shape of the front chassis 1 may be illustrated as shown in FIG. Is protruded into the tuner through the through hole 5 of the insulating plate 6, and the soldering portions 9 and 9 'are formed on the terminal pin 7 and the protruding ground protrusion 3, respectively. Bypass capacitor (8) can be connected.
상기와 같은 구성 및 작용을 통해 본 고안은 최근 접한 거리에서 신호 전원단의 단자핀(7)을 콘덴서(8)를 통해 전면샤씨(1)에다 접지시켜줄수 있으므로 양호한 바이패쓰효과를 얻을수 있으며, 그에따라 고가의 피드쓰루 콘덴서를 사용하거나 별도의 쵸크코일을 사용할 필요가 없으므로 원가를 절감하고 그 구조를 간단하게 할 뿐만 아니라 양호한 바이패쓰 기능을 갖는 소형튜너를 제공할수 있는 효과가 있다.Through the construction and operation as described above, the present invention can obtain a good bypass effect because the terminal pin 7 of the signal power supply terminal can be grounded to the front chassis 1 through the condenser 8 at a close distance. Therefore, there is no need to use expensive feed-through capacitors or separate choke coils, thereby reducing costs and simplifying the structure, and providing a small tuner with good bypass function.
