본 고안은 음향기기 포인타의 발광다이오우드 구동와이어가 회로부품등에 접촉됨을 방지하고, 튜닝 구동의 원할함을 꾀할 수 있게 한 포안타의 발광장치에 관한 것이다.The present invention relates to a light-emitting device of a po-ant that prevents the light-emitting diode driving wire of an acoustic device pointer from contacting a circuit component and the like, and facilitates tuning drive.

종래, 포인타와이어를 고정하는 방법으로 셋트일측에 고정된 홀더스프링을 이용하는 포안타 발광장치는 포인타회로기판(151)에 발광다이오우드(161)를 설치하고, 발광다이오우드(161)를 구동시키기 위한 포인타와 이어 (711)(712)를 메인회로기판에 연결하여 튜닝동작을 행하게 되면, 포안타와이어(711)(712)가 회로부품이 나 셋틀일측에 걸려 동작성이 불량이 생기는 원인이 되었다.Conventionally, a four-antenna light emitting device using a holder spring fixed to a set side by fixing a pointer wire is provided with a light emitting diode 161 on a pointer circuit board 151 for driving the light emitting diode 161. When the tie wires 711 and 712 are connected to the main circuit board and the tuning operation is performed, the four wires 711 and 712 are caught on one side of the circuit component or set, causing malfunction. .

이를 해결하기 위하여 중간부위에 홀더스프링(611)을 이용하여 포안타와이어(711)(712)를 잡아주었으나 이러한 종래의 장치에 있어서는 튜닝동작을 거듭 행함에 따라 포안타아이어(711)(712)가 홀더스프링(611)에서 이탈되는 문제가 발생하였으며, 셋트 내부의 공간이 작을 경우에는 적용하지 못하는 문제점이 있었다.In order to solve this problem, the pinnaire wires 711 and 712 are held by using the holder springs 611 in the middle portion. However, in the conventional apparatus, as the tuning operation is repeatedly performed, the poantairs 711 and 712 are performed. There is a problem that is separated from the holder spring 611, there was a problem that can not be applied when the space inside the set is small.

또한 내부 공간이 작을 때에는 전면 다이얼스케일을 이용하는 방법도 시행되었으나 튜닝 동작이 원활하지 못함이 문제점으로 남아 있었다.In addition, when the internal space is small, the method of using the front dial scale was also implemented, but the problem was that the tuning operation was not smooth.

본 고안은 이와 같은 제결점을 해결하기 위하여 안출된 것으로써 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such drawbacks and will be described in detail by the accompanying drawings as follows.

전면에는 윈도우다이얼(2)과 내측에는 다이얼스케일(3)이 설치된 판넬프론트(1)의 내상측부에, 요입홈(4)(401)이 형성된 가이드판(5)을 돌출형성하고, 이에 연결스프링(6)(601)을 삽입설치하여 일측에 포안타와이어(7)(701)를 접속시킨다.On the inner side of the panel front (1) in which the window dial (2) and the dial scale (3) are installed on the front side, a guide plate (5) having recessed grooves (4) (401) is formed thereon, and a connection spring (6) (601) is inserted and the four-antenna wire (7) (701) is connected to one side.

가이드홈(9)이 있는 포인타(8)의 상부에는, 삽입공(10)(10)를 형성하여, 걸림턱(11)(111)과 접속부(12)(121)를 가진 접속편(13)(131)을 삽입설치하고, 후측으로 돌출형성된 록킹부(14)에는 회로기판(15)과 발광다이오우드(16)를 설치하여, 통공(17)을 통하여 발광 될수 있도록 접속편(13)(131)과 회로기판(15) 사이를 접속전원선(18)(181)으로 연결한 다음, 판넬프론트(1)의 가이드판(5)에 포인타(8)의 가이드홈(9)을 삽입하여 결합구성된 것이다.An insertion hole 10, 10 is formed in the upper part of the pointer 8 with the guide groove 9, and the connecting piece 13 having the locking jaws 11, 111 and the connection part 12, 121 is formed. 131 is inserted into the locking portion 14 protruding to the rear side, and a circuit board 15 and a light emitting diode 16 are provided to connect the connecting pieces 13 and 131 to emit light through the through hole 17. ) And the circuit board 15 by connecting power lines 18 and 181, and then the guide groove 9 of the pointer 8 is inserted into the guide plate 5 of the panel front 1 to be coupled. It is composed.

상기와 같이 구성된 본 고안은, 메인기판의 신호가 포안타와이어(7)(701)를 통하여, 판넬프론트(1)의 가이드판(5)에 설치된 연결스프링(16)(601)에 흐르게 되며, 이때 제2도에서 도시한 바와 같이, 접속편(13)(131)의 접속부(12)(121)가 연결스프링(6)(601)과 조립접속되어 접속전원선(18)(181)를 통하여 발광다이오우드(16)를 발광시키게 된다.According to the present invention configured as described above, the signal of the main board flows through the connecting wires 16 and 601 installed on the guide plate 5 of the panel front 1 through the poant wires 7 and 701, At this time, as shown in FIG. 2, the connecting portions 12 and 121 of the connecting pieces 13 and 131 are assembled and connected to the connecting springs 6 and 601 through the connecting power lines 18 and 181. The light emitting diode 16 is made to emit light.

이와 같은 상태에서 좌우방향으로 튜닝동작을 하게되면 접속편(13)(131)의 접속부(12)(121)가 연결스프링(6)(601)을 타고 동작하게되므로 발광다이오우드(16)는 계속 발광상태를 유지하게되어, 포안타와이어(7)(701)가 주위의 회로부품에 접촉될 염려가 없게 되며, 원할한 튜닝 구동을 꾀할 뿐만아니라, 내부공간이 작은 셋트에도 적용이 용이한 특징으로 지닌 것이다.In this state, when the tuning operation is performed in the left and right directions, the light emitting diodes 16 continue to emit light because the connecting portions 12 and 121 of the connecting pieces 13 and 131 operate on the connecting springs 6 and 601. The state is maintained so that the pore wires 7 and 701 are not in contact with the surrounding circuit components, and smooth tuning drive is achieved, and it is easy to apply to a set with a small internal space. will be.
