본 발명은 각종 통신 및 전자기기의 키 버튼과 피씨비(PCB) 사이에 조립된 The present invention is assembled between the key button and the PCB (PCB) of various communication and electronic devices
메탈돔에 관한 것으로 접점부의 접지 신뢰성을 높이기 위해 고안된 기술이다. Metal dome is a technology designed to improve the grounding reliability of the contact portion.
도 1은 종래의 일반적인 원형 메탈돔 방식으로 접점부에 접지 신뢰성을 위한 1 is a conventional circular metal dome method for a conventional grounding reliability
추가적인 구조가 없는 방식과 도 2a 및 도 2b는 접점부를 딤플로 형성하여 There is no additional structure and FIGS. 2A and 2B show that the contact portion is dimpled
접지 신뢰성을 높인 것이다. The ground reliability is increased.
도 2는 접점부를 프레스 금형에서 엠보싱 하여 돌기를 형성 하므로서 키 버튼이 Figure 2 is a key button by forming a projection by embossing the contact portion in the press mold
눌려질 때 접지 신뢰성을 높일 수 있는 구조이다. 하지만 이러한 구조도 메탈돔 It is a structure that can increase the ground reliability when pressed. But this structure is also a metal dome
내부의 미세 먼지나 피씨비(PCB) 면의 이물에 의한 불량을 완전히 방지하지는 Do not completely prevent defects caused by fine dust inside or foreign matter on the PCB surface.
못했다. 따라서 본 고안은 이러한 불량률을 줄이기 위해 고안되었다. I couldn't. Therefore, the present invention is designed to reduce such defective rate.
단수 또는 복수의 슬리팅 또는 슬릿 벤딩으로 메탈돔 내측에 접점부을 구비함 Single or multiple slitting or slit bending with contacts inside the metal dome
으로써 종래의 문제점을 해결할 수 있다. This can solve the conventional problem.
슬릿 밴딩은 프레스 가공에서 일반적으로 사용되는 방식으로 메탈돔에 접Slit banding is in contact with metal domes in a manner commonly used in press working.
목하는 것이다. 슬릿 밴딩에 의한 높이는 0.005~0.1mm 사이에 돌출 높이를It is to. The height due to slit banding increases the protruding height between 0.005 ~ 0.1mm
조정하는 것이 이상적이다.It is ideal to adjust.
본 발명은 각종 통신기기 단말기의 메탈돔 스위치의 이러한 접지의 불량을 해결 The present invention solves this poor grounding of the metal dome switch of various communication device terminals
하기 위해 메탈돔 내측 면에 단수 또는 복수의 프레스 슬릿밴딩(31) 가공으로 Single or multiple press slit banding 31 on the inner surface of the metal dome
내측에 접점부(32,33)을 형성하여 구성된 이동통신 단말기의 메탈돔 스위치를 The metal dome switch of the mobile communication terminal formed by forming
구조에 관한 것이다. 즉 V 또는 U 자 형태의 프레스 슬릿밴딩을 통하여 만들어진 It's about structure. Ie through V-shaped U-shaped press slit banding
내측 돌출부는 내측에 접점부(32,33)을 형성하게 된다. The inner protrusions form
슬릿밴딩(31)의 수는 3 ~ 4개가 형성되는 것이 메탈돔 스위치의 내구성과 접지 Durability and grounding of the metal dome switch is that the number of the
신뢰성이 최적으로 보장되겠다. Reliability will be guaranteed optimally.
표시된 바와 같이 구형상의 메탈돔 스위치 내측 면에 단수 또는 복수의 프레스 Single or multiple presses on the inner side of the spherical metal dome switch as shown
가공을 통한 슬릿밴딩(31)으로 메탈돔의 접지 신뢰성을 높일 수 있는 접점부를 Slit banding (31) through processing to improve the contact reliability of the metal dome grounding
형성하고 있다. 이러한 접점부는 프레스 가공 방법인 슬릿벤딩(31) 작업으로 Forming. This contact part is a slit bending (31) operation that is a press working method
형성되어 접점부는 날카로운 절단면을 갖는다. 이런 특징을 가진 다수의 접점부 Formed so that the contact portion has a sharp cut surface. Multiple contacts with this feature
는 피씨비(PCB)면에 형성된 이물층이나 조립 또는 사용 중 이물이 유입되어도 The foreign material layer formed on the PCB surface or foreign matters during assembly or use
접지의 신뢰성를 높일 수 있다. The reliability of the ground can be improved.
또한 다른 특징의 하나는 슬릿(Slit) 작업을 통해 메탈돔이 동작 시 내부공간이 In addition, one of the other features is the slit (slit) work, the internal space is reduced when the metal dome is operating
작아지면서 발생되는 공기의 유출을 도와 에어벤트(Airvent) 역할을 동시에 할 It helps air outflow as it gets smaller and at the same time acts as an air vent
수 있는 특징이 있다. There are features that can be.
첨부된 그림에 예시는 원형돔 스위치를 기준으로 한 것이며 유사한 예로 The examples in the accompanying figures are based on a round dome switch and similar examples
양방향이 컷(CUT)되어 있는 형태의 디알(DR)돔 스위치에 형성되어 있는 슬릿 Slit formed in the DR dome switch of the cut type in both directions
밴딩 접점부도 청구 범위 내에 포함된다 하겠다. Banding contacts are also included within the scope of the claims.
상기에 기술된 본 고안은 바람직한 하나의 실시 예로서 이에 한정되지 아니하며 The present invention described above is not limited thereto as one preferred embodiment
