본 고안은 음향기기의 볼륨 조절장치에 관한 것으로서, 더욱 상세하게는 볼륨 조절용 손잡이에 형성된 램프로 전원을 공급하는 와이어가 손잡이의 회전시 꼬이지 않도록 함으로서, 신뢰성이 향상되도록한 음향기기의 볼륨 조절장치에 관한 것이다.The present invention relates to a volume control device for an audio device, and more particularly, a wire for supplying power to a lamp formed on the volume control knob does not twist when the handle is rotated, thereby improving the reliability of the volume control device for the audio device. It is about.

일반적으로 음향기기에 사용되는 볼륨 조절장치는 로터리 방식의 손잡이를 사용한다. 즉 손잡이가 회전됨에 따라 로터리스위치가 작동되어 볼륨이 조절된다. 제1도는종래 볼륨 조절장치를 나타낸 단면도로서, 판넬(1)의 외측으로 돌출된 손잡이(4)의 일측에 LED의 일종인 발광램프(5)가 매설되어 손잡이(4)의 전방으로 발광된다.In general, the volume control used for sound equipment uses a rotary knob. In other words, as the knob rotates, the rotary switch is operated to adjust the volume. 1 is a cross-sectional view showing a conventional volume control device, a light emitting lamp 5, which is a kind of LED, is embedded on one side of the handle 4 protruding to the outside of the panel 1 to emit light toward the front of the handle 4.

또한 손잡이(4)는 축(2a)과 연결되고 축(2a)의 단부에 종동기어(3b)가 설치되고 또한 모터(3)로 구동되는 구동기어(3a)와 치합된 상태에서 리모트콘트롤되면 축(2a)이 자동으로 회전된다. 한편 축(2a)의 일측으로 로터리스위치(2)가 설치되어 축(2a)의 회전에 따라 작동되어 볼륨이 조절된다.In addition, the handle 4 is connected to the shaft (2a), the driven gear (3b) is installed at the end of the shaft (2a) and the remote control in the state of meshing with the drive gear (3a) driven by the motor (3) (2a) is automatically rotated. On the other hand, the rotary switch 2 is installed on one side of the shaft (2a) is operated in accordance with the rotation of the shaft (2a) to adjust the volume.

이처럼 구성된 종래의 볼륨 조절장치는 모터(3)의 구동으로 손잡이(4)가 회전되면 발광램프(5)가 와이어(6)를 통하여 인가되는 전원에 의해 발광되면서 손잡이(4)의 회전상태가 외부로 표시된다. 그러나 발광램프(5)가 와이어(6)를 통하여 직접 연결된 상태이므로 손잡이(4)가 회전되는 동안 와이어(6)가 꼬일 우려가 있다.In the conventional volume control device configured as described above, when the knob 4 is rotated by the driving of the motor 3, the light emitting lamp 5 is emitted by the power applied through the wire 6, and the rotation state of the knob 4 is external. Is displayed. However, since the light emitting lamp 5 is directly connected through the wire 6, the wire 6 may be twisted while the handle 4 is rotated.

즉 판넬(1)에 형성된 구멍(1a)을 통하여 와이어(6)가 손잡이(4) 내측으로 연장된 다음 발광램프(5)와 연결됨으로 손잡이(4)가 회전되는 동안 와이어(6)가 축(2a)의 외주면과 간섭되어 노이즈현상이 발생되고 또한 와이어(6)가 항상 유동됨으로 피로가 증가되어 와이어(6)가 단선될 우려가 있는 등의 단점이 있다.In other words, the wire 6 extends into the handle 4 through the hole 1a formed in the panel 1 and is then connected to the light emitting lamp 5 so that the wire 6 is rotated while the handle 4 is rotated. Noise phenomenon occurs due to interference with the outer circumferential surface of 2a), and the wire 6 is always flowed, so that the fatigue is increased and the wire 6 may be disconnected.

본 고안은 종래의 문제점을 감안하여 개발된 것으로서, 그 목적은 손잡이의 회전시 와이어와 발광램프가 점접촉에 의해 전원이 항상 공급되도록 함으로서, 와이어의 꼬임이 방지되고 또한 신뢰성이 향상된 음향기기의 볼륨 조절장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and its purpose is to ensure that power is always supplied by the point contact of the wire and the light emitting lamp when the handle is rotated, thereby preventing the twisting of the wire and improving the volume of the acoustic device. In providing an adjusting device.

상기 목적을 달성하기 위하여 본 고안은 모터로 회전되는 축의 전방으로 손잡이가 설치되고 또한 축의 일측에 로터리스위치가 설치되어 볼륨이 조절됨에 있어서, 상기 손잡이의 전방으로 표출되고 리이드를 갖는 발광램프와; 상기 리이드의 회전괘적과 대응되도록 원호형으로 형성된 고정단자를 갖는 인쇄회로기판과; 그리고 상기 리이드와 고정단자 사이에 설치되어 이들을 전기적으로 연결하는 연결단자가 구비된 특징이 있다.In order to achieve the above object, the present invention provides a handle that is installed in front of a shaft rotated by a motor, and a rotary switch is installed on one side of the shaft so that the volume is controlled, the light emitting lamp having a lead and the front of the handle; A printed circuit board having fixed terminals formed in an arc shape so as to correspond to the rotation path of the lead; And it is characterized in that the connection terminal is provided between the lead and the fixed terminal to electrically connect them.

이하에서는 본 고안의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안 볼륨 조절장치의 단면도로서, 판넬(10)의 외부로 돌출된 축(21)의 선단부에 발광램프(40)가 결합된 손잡이(30)의 허브(31)가 끼워져 회전된다. 축(21)은 판넬(10) 내측에 설치된 로터리스위치(20)와 결합되고 축(21)의 후단에 종동기어(22)가 결합된다. 그리고 종동기어(22)는 모터(24)로 회전되는 구동기어(23)와 치합되어 자동으로 회전된다.2 is a cross-sectional view of the present invention, the volume control device, the hub 31 of the handle 30, the light emitting lamp 40 is coupled to the front end of the shaft 21 protruding to the outside of the panel 10 is inserted and rotated. The shaft 21 is coupled to the rotary switch 20 installed inside the panel 10 and the driven gear 22 is coupled to the rear end of the shaft 21. In addition, the driven gear 22 meshes with the driving gear 23 rotated by the motor 24 and automatically rotates.

또한 손잡이(30)의 회전시 함께 회전되는 발광램프(40)의 회전괘적과 대응되도록 판넬(10)에 원호형의 구멍(11)이 형성되고 판넬(10) 내측면에는 구멍(11)을 덮는 크기로 제작된 인쇄회로기판(50)이 나사못(53)을 통하여 결합된다. 인쇄회로기판(50)에는 제3도에 도시된 바와 같이 반원호형으로 구성되어 와이어(52)와 연결된 한쌍의 고정단자(51)가 형성된다.In addition, an arc-shaped hole 11 is formed in the panel 10 so as to correspond to the rotational rule of the light emitting lamp 40 which is rotated when the handle 30 is rotated, and covers the hole 11 on the inner surface of the panel 10. The printed circuit board 50 manufactured in size is coupled through the screw 53. As shown in FIG. 3, the printed circuit board 50 has a pair of fixed terminals 51 formed in a semicircular arc shape and connected to the wire 52.

그리고 발광램프(40)의 리이드(41)와 고정단자(51) 사이에 연결단자(70)가 설치된다. 연결단자(70)는 일측단이 스프링(80)을 통하여 리이드(41)와 접촉되고 타측단은 고정단자(51)와 점접촉된다. 또한 연결단자(70)와 스프링(80)은 케이스(60)에 내장되고 케이스(60)는 손잡이(30) 내부에 고정 설치된다.A connection terminal 70 is installed between the lead 41 and the fixed terminal 51 of the light emitting lamp 40. One end of the connection terminal 70 is in contact with the lead 41 through the spring 80 and the other end is in point contact with the fixed terminal 51. In addition, the connection terminal 70 and the spring 80 is built in the case 60 and the case 60 is fixedly installed in the handle 30.

이처럼 구성된 본 고안은 모터(24)의 구동으로 구동기어(23)가 회전되면 종동기어(22)가 함께 회전되고 이때 축(21)이 회전된다. 또한 축(21)의 회전으로 손잡이(30)가 자동으로 회전 조절되고 이때 로터리스위치(20)가 작동되어 볼륨이 조절된다. 또한 축(21)이 회전되는 동안 발광램프(40)가 작동된다.When the driving gear 23 is rotated by the driving of the motor 24, the present invention configured as described above rotates the driven gear 22 together with the shaft 21. In addition, the knob 30 is automatically rotated by the rotation of the shaft 21, and at this time, the rotary switch 20 is operated to adjust the volume. In addition, the light emitting lamp 40 is operated while the shaft 21 is being rotated.

즉 와이어(52)와 연결된 인쇄회로기판(50)의 각 고정단자(51)에 전원이 인가되면 이와 점접촉된 연결단자(70)를 통하여 리이드(41) 쪽으로 전원이 인가되고 이때 발광램프(40)가 점등된다. 또한 손잡이(30)의 회전으로 발광램프(40)가 회전되면 이와 동시에 케이스(60)가 함께 회전된다. 이때 케이스(60)에 내장된 연결단자(70)가 원호형으로 형성된 구멍(11)을 따라 회전되면서 고정단자(51)와 계속 접촉됨으로 전원이 발광램프(40) 쪽으로 계속 공급된다. 또한 스프링(80)에 의해 각 연결단자(70)가 고정단자(51)와 접촉됨으로 단락되지 않는다.That is, when power is applied to each of the fixed terminals 51 of the printed circuit board 50 connected to the wire 52, the power is applied toward the lead 41 through the connection terminal 70 in point contact with the light emitting lamp 40. ) Lights up. In addition, when the light emitting lamp 40 is rotated by the rotation of the handle 30, the case 60 is rotated at the same time. At this time, the connection terminal 70 embedded in the case 60 is rotated along the hole 11 formed in an arc shape, and thus is continuously contacted with the fixed terminal 51, so that power is continuously supplied toward the light emitting lamp 40. In addition, the connection terminal 70 is not short-circuited by contact with the fixed terminal 51 by the spring 80.

이상에서와 같이 본 고안에 따르면 손잡이에 형성된 발광램프가 스프링으로 가압되는 연결단자와 전기적으로 통전되고 또한 연결단자는 인쇄회로기판에 원호형으로 형성된 고정단자에 점접촉된다. 따라서 손잡이가 회전되면 연결단자를 통하여 고정단자의 전원이 발광램프 쪽으로 인가되어 발광됨에 따라 와이어가 꼬일 우려가 감소되는 등의 효과가 있다.As described above, according to the present invention, the light emitting lamp formed on the handle is electrically energized with the connecting terminal pressurized by the spring, and the connecting terminal is in point contact with the fixed terminal formed in an arc shape on the printed circuit board. Therefore, when the handle is rotated, as the power of the fixed terminal is applied toward the light emitting lamp through the connection terminal and the light is emitted, there is an effect of reducing the possibility of twisting the wire.
