일반적으로 제1도는 TV 안테나 접속이 완료된 상태를 나타내는 사시도로서, 텔레비젼 안테나(1)로부터 수시된 신호는 케이블(2)과 안테나 장치(3)를 통해 텔레비젼 수상기(4) 내부의 튜너와 인쇄회로기판(PCB)으로 인가되게 연결되는 바, 종래의 안테나 장치(3)는 안테나 그라운드(5)와 소자 그라운드(6)가 좁게 형성되어져 별도로 과도전류를 방출시킬수 없는 바, 낙뢰인가시 안테나 그라운드(5)와 소자 그라운드(6)를 통해 인쇄회로기판(PCB)까지 영향을 주므로써 안테나 실드장치(3)는 물론 텔레비젼 회로까지 파손되는 문제점이 있었다.1 is a perspective view showing the state in which the TV antenna connection is completed, and the signal received from the TV antenna 1 is a tuner and a printed circuit board inside the TV receiver 4 through the cable 2 and the antenna device 3. The antenna device 3 of the conventional antenna device 3 has a narrow antenna ground 5 and an element ground 6, and cannot separately emit a transient current. By affecting the printed circuit board (PCB) through the device ground (6), there was a problem that the antenna shield device (3) as well as the television circuit is damaged.

이에 본 고안은 이와 같은 문제점을 해결하고자 안출한 것으로, 안테나장치(3)의 안테나 그라운드(5)와 소자 그라운드(6)를 넓게 형성하고 인쇄회로기판(PCB) 상의 튜너메인 그라운드(7)를 파우워 그라운드(8)에 연결함으로써 낙뢰에 따른 과전류, 과전압 인가시 파우워 그라운드(8)의 과도전압이 패턴(P1,P2)을 통해 파우워 코드단(미도시됨)으로 방출할 수 있도록 한 낙뢰방지용 안테나 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and the antenna ground 5 and the element ground 6 of the antenna device 3 are widely formed, and the tuner main ground 7 on the printed circuit board PCB is grounded. Lightning that allows the overvoltage of the power ground 8 to be discharged to the power cord terminal (not shown) through the patterns P1 and P2 when the overcurrent and overvoltage are applied due to the lightning. It is an object of the present invention to provide an antenna device for prevention.

이러한 목적을 달성하기 위한 본 고안은 입력단자(9)와 출력단자(10)를 가지는 낙뢰방지용 안테나 장치가 TV 내부의 튜너와 PCB(11)상의 파우워 그라운드(8)를 튜너메인 그라운드(7)에 연결하고, 상기 파우워 그라운드(8)로부터 과도한 전류, 전압이 패턴(P1,P2)을 통해 파우워 코드단으로 방출될 수 있도록 형성한다.The present invention for achieving this purpose is that the lightning protection antenna device having an input terminal (9) and an output terminal (10) tunes the power ground (8) on the tuner and PCB (11) inside the TV tuner main ground (7) And excessive current and voltage from the power ground 8 can be discharged to the power cord terminal through the patterns P1 and P2.

이하 본 고안을 첨부된 도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도는 종래의 안테나 실드 장치의 사시도 및 저면도로서, 텔레비젼 안테나(1)의 케이블(2)은 안테나 장치(3)의 입력단자(9)에 접속되고, 상기 안테나 실드박스(3)의 출력단자(10)는 안테나 입력단자(12)에 접속된다.2 is a perspective view and a bottom view of a conventional antenna shield device, wherein the cable 2 of the television antenna 1 is connected to the input terminal 9 of the antenna device 3, and the output of the antenna shield box 3 is shown. The terminal 10 is connected to the antenna input terminal 12.

또한 안테나 입력단자(12)는 케이블(2')을 통해 튜너의 인쇄회로기판(PCB)(11)으로 접속되는바, 종래의 안테나 장치의 저면도로서 안테나 장치(3)의 안테나 그라운드(5)와 소자 그라운드(6)를 좁게 형성됨을 나타내고 있다.The antenna input terminal 12 is also connected to the tuner's printed circuit board (PCB) 11 via a cable 2 ', which is the bottom view of a conventional antenna device, which is the antenna ground 5 of the antenna device 3. And the element ground 6 is narrowly formed.

제3도는 본 고안에 따른 낙뢰방지용 안테나 장치의 사시도 및 저면도로서, 낙뢰 인가시 텔레비젼 안테나(1)의 케이블(2)을 통해 과도한 전류, 전압이 낙뢰방지용 안테나 장치(3)의 입력단자(9)를 통해 인가되면 상기 인가된 과도전류, 전압은 안테나 그라운드(5)와 소자 그라운드(6)로 방출된다.3 is a perspective view and a bottom view of the lightning protection antenna device according to the present invention, the excessive current, voltage through the cable (2) of the television antenna 1 when lightning is applied to the input terminal (9) of the lightning protection antenna device (3) When applied through), the applied transient current and voltage are emitted to the antenna ground 5 and the device ground 6.

상기에서 방출되지 못한 과도전류, 전압이 낙뢰방지용 안테나 장치(3)의 출력단자(10)와 안테나 입력단자(9)를 통해 인가된 과도전류 및 전압이 튜너메인 그라운드(7)를 거쳐 파우워 그라운드(8)로 인가된 다음 패턴(P1,P2)을 통해 파우워 코드단(미도시됨)으로 방출할 수 있는 것이다.The transient current and the voltage which are not emitted from the above are applied to the output terminal 10 and the antenna input terminal 9 of the lightning protection antenna device 3 through the tuner main ground 7 through the power ground. It can be emitted to the power cord stage (not shown) through the next pattern (P1, P2) applied to (8).

이와 같이 본 고안은 낙뢰시 기존의 안테나 장치를 사용하면 안테나 장치는 물론이고 메인 PCB까지도 영향을 미쳐 파괴가 일어나 텔레비젼이 치명적으로 파손되는 것을 방지할 수 있는 효과가 있다.As such, the present invention has an effect of preventing damage to the TV by causing damage by using the existing antenna device during a lightning strike, affecting not only the antenna device but also the main PCB.
