Description

로터리 스위치 조립체 {A rotary switch assembly}Rotary switch assembly {A rotary switch assembly}

본 발명은 로터리 스위치 조립체에 관한 것으로써, 특히 회전노브가 흔들림이 없이 회전되어 이를 채용하는 제품의 품질을 향상시키고 또한 회전노브의 회전시 작동음을 명쾌하게 발생하게 하여 소비자로 하여금 회전제어 정도를 직감할 수 있도록 개선된 로터리 스위치 조립체에 관한 것이다.The present invention relates to a rotary switch assembly, in particular, the rotary knob is rotated without shaking to improve the quality of the product employing it, and also to generate a clear operation sound when the rotary knob rotates to the consumer to control the degree of rotation control A rotary switch assembly that has been improved to be intuitive.

일반적으로 로터리 스위치는 금속재의 탄성판이 스위치패턴에 슬라이딩 접촉하게 되어 스위치의 on/off 작동이 이루어진다.In general, the rotary switch is in contact with the switch pattern of the elastic plate of the metal material is made to switch on / off operation.

이와 같은 로터리 스위치의 일 예가 도 1 및 도 2에 도시되어 있다. 이것은 세탁기의 운전모드를 선택하는 로터리 스위치를 나타낸 것으로써, 원형홈(11)의 바닥면에 스위치패턴(14)이 조립되고 단자(15)가 외부로 돌출된 고정체(10)와, 이 고정체(10)의 원형홈(11)에 회전가능하게 수용되며 외주면에 일정간격으로 요철(22)이 형성되고 저면에는 스위치패턴(14)에 슬라이딩 접촉되는 탄성판(23)이 조립되며 상부측에는 샤프트(21)가 형성된 회전체(20)와, 고정체(10)의 원형홈(11)측으로 출몰가능하게 조립되어 요철(22)에 탄성적으로 접촉하는 록킹볼(13)과, 록킹볼(13)에 탄성력을 부여하는 스프링(12)과, 고정체(10)로부터 회전체(20)의 이탈을 방지시키도록 고정체(10)에 결합되는 덮개판(30)과, 회전체(20)의 샤프트(21)에 결합되어 회전체(20)를 회전조작하는 회전노브(40)로 이루어진다.An example of such a rotary switch is shown in FIGS. 1 and 2. This is a rotary switch for selecting the operation mode of the washing machine, the switch pattern 14 is assembled to the bottom surface of the circular groove 11, the fixing body 10, the terminal 15 protrudes outward, An elastic plate 23 is rotatably received in the circular groove 11 of the stagnation 10, and the irregularities 22 are formed on the outer circumferential surface at regular intervals, and the elastic plate 23 sliding on the switch pattern 14 is assembled on the bottom of the shaft 10. A rotating body 20 having a 21 formed thereon, a locking ball 13 assembled to be protruded toward the circular groove 11 side of the fixed body 10 and elastically contacting the unevenness 22, and the locking ball 13 Spring 12 to give elastic force to the), the cover plate 30 is coupled to the fixed body 10 to prevent separation of the rotating body 20 from the fixed body 10, and the rotating body of the Is coupled to the shaft 21 is composed of a rotary knob 40 for rotating the rotating body 20.

이와 같은 로터리 스위치는 회전노브(40)를 소망하는 작동모드로 회전시킬 때 회전체(20)가 회전되면서 탄성판(23)이 스위치패턴(14)에 슬라이딩 접촉되어 해당 작동모드의 전원을 ON시키게 된다.Such a rotary switch causes the elastic plate 23 to slide in contact with the switch pattern 14 while the rotary body 20 is rotated when the rotary knob 40 is rotated to a desired operation mode, thereby turning on the power of the corresponding operation mode. do.

이때 록킹볼(13)은 스프링(12)에 의해서 회전체(20)의 외주면 요철(22)에 탄력적으로 접촉되면서 작동음을 발생시킬 뿐만 아니라 탄성판(23)과 스위치패턴(14)의 접촉위치를 정확하게 제어할 수 있도록 한다.At this time, the locking ball 13 elastically contacts the outer circumferential surface unevenness 22 of the rotating body 20 by the spring 12 to generate the operation sound, as well as the contact position between the elastic plate 23 and the switch pattern 14. So that it can be controlled precisely.

그러나 위와 같은 로터리스위치는 스프링(12)에 의해서 회전체(20)가 일방향으로 탄력이 부여되게 되므로 회전노브(40)가 회전될때 중심축에 대하여 좌우로 요동되게 된다. 이때 고정체(10)의 원형홈(11) 내주면과 회전체(20)의 외주면 사이의 간극이 클수록 회전노브(40)의 요동이 더 심하게 발생되게 된다.However, since the rotary switch 20 is provided with elasticity in one direction by the spring 12, the rotary switch is swung left and right with respect to the central axis when the rotary knob 40 is rotated. At this time, the greater the gap between the inner circumferential surface of the circular groove 11 of the fixed body 10 and the outer circumferential surface of the rotating body 20, the more the fluctuation of the rotary knob 40 is generated.

또한, 회전노브(40)는 통상 사용자들이 제어할 수 있도록 제품의 표면에 노출되게 되므로, 요동되는 회전노브(40)를 채용한 세탁기와 같은 제품의 품질을 저하시키게 된다.In addition, since the rotary knob 40 is typically exposed to the surface of the product so that the user can control, it is to reduce the quality of the product, such as a washing machine employing the swing knob 40 is shaken.

또한, 위와 같은 로터리 스위치에 채용되는 스프링(12)과 록킹볼(13)은 소형으로서 조립이 불편하다.In addition, the spring 12 and the locking ball 13 employed in the rotary switch as described above are small and inconvenient to assemble.

또한, 록킹볼(13)이 요철(22)에 구름접촉되므로 스프링(12)의 채용에도 불구하고 작동음이 작게 발생되어 이용자로 하여금 청각에 의한 회전정도를 직감하기 곤란하다.In addition, since the locking ball 13 is in contact with the concave-convex 22, the operation sound is generated in spite of the adoption of the spring 12, so that it is difficult for the user to sense the degree of rotation by hearing.

본 발명은 회전노브의 회전시 좌우 요동없이 회전될 수 있도록 개선된 로터리 스위치 조립체를 제공하는 데 그 기술적 과제가 있다.The present invention has a technical problem to provide an improved rotary switch assembly to be rotated without the left and right swings when rotating the rotary knob.

도 3 및 도 4를 참조하면, 이 조립체는 원형홈(111)의 바닥면에 고정자(114)가 조립된 고정체(110)와, 이 고정체(110)의 원형홈(111)에 회전가능하게 수용되며 외주면에 일정간격으로 요철(122)이 형성되고 저면에는 고정자(114)에 슬라이딩 접촉되는 회전자(123)가 조립되며 상부측에는 회전노브(140)가 결합되는 샤프트(121)가 형성된 회전체(120)와, 회전체(120)의 회전위치를 유지시키는 회전유지수단을 구비한다.3 and 4, the assembly is rotatable in the fixture 110 having the stator 114 assembled to the bottom surface of the circular groove 111, and the circular groove 111 of the fixture 110. And the rotor 123 is slidably contacted with the stator 114 at a predetermined interval on the outer circumferential surface thereof, and the shaft 121 at which the rotary knob 140 is coupled to the upper side is formed. The whole 120 and the rotation holding means for maintaining the rotation position of the rotating body 120 is provided.

회전자(123)는 탄성변형이 가능한 탄성판으로 구성하였으며, 상기 고정자(114)는 작동모드에 따른 스위치패턴으로서 단자(115)와 전기적으로 연결된다.The rotor 123 is composed of an elastic plate capable of elastic deformation, and the stator 114 is electrically connected to the terminal 115 as a switch pattern according to an operation mode.

상기 회전유지수단은 상기 고정체(110)에 결합되며 그 중앙부분에 상기 요철(122)에 탄력적으로 접촉하는 돌출부(112a)가 형성된 제1판스프링(112)과, 상기 제1판스프링(112)의 배면측에 위치되어 상기 고정체(110)에 결합되며 상기 제1판스프링(112)의 탄성변형 후 복귀시에 상호 접촉되어 마찰 및 충돌음을 발생시키는 보조판스프링(118)과, 상기 제1판스프링(112)에 대향된 위치에서 상기 고정체(110)에 결합되어 상기 요철(122)에 탄력적으로 접촉하는 돌출부(113a)가 형성된 제2판스프링(113)을 구비한다.The rotation holding means is coupled to the fixing body 110 and the first plate spring 112 and the first plate spring 112 formed with a protrusion 112a in elastic contact with the concave-convex 122 at the center portion thereof. And an auxiliary plate spring 118 coupled to the fixing body 110 and contacting each other when the first plate spring 112 returns after elastic deformation to generate friction and impact sounds. The second leaf spring 113 is coupled to the fixed body 110 at a position opposite to the leaf spring 112 and has a protrusion 113a formed to elastically contact the unevenness 122.

미설명부호 130은 덮개판으로서 고정체(110)에 결합되어 회전체(120)의 이탈을 방지하게 한다.Reference numeral 130 is coupled to the fixing body 110 as a cover plate to prevent the departure of the rotating body 120.

이와 같은 로터리 스위치 조립체는 회전노브(140)를 소망하는 작동모드로 회전시킬때 회전체(120)가 회전되면서 회전자(123)가 고정자(114)에 슬라이딩 접촉되어 해당 작동모드의 전원을 ON시키게 된다.The rotary switch assembly is such that when the rotary knob 140 is rotated to the desired operation mode, the rotor 120 rotates and the rotor 123 is in sliding contact with the stator 114 to turn on the power of the corresponding operation mode. do.

이때 제1판스프링(112)의 돌출부(112a)는 회전체(120)의 외주면 요철(122)에 탄력적으로 접촉되면서 제1판스프링(112)이 탄성변형이 되게 되며, 탄성변형되는 동안 제1판스프링(112)의 양단부가 보조판스프링(118)에 마찰되어 마찰음을 발생하며 탄성복귀시에는 보조판스프링(118)과 충돌되어 충돌음을 발생하게 된다.At this time, the protrusion 112a of the first leaf spring 112 is in elastic contact with the outer circumferential surface irregularities 122 of the rotating body 120 such that the first leaf spring 112 is elastically deformed, and the first plate spring 112 is elastically deformed.
