고안의 분야Field of devise
본 고안은 전화기 또는 기타 전자제품에 사용되는 누름스위치에 관한 것으로서, 특히 내부에 LED램프를 내장하여 스위치를 눌려줌에 따라서 야간에 식별이 가능하도록 스위치의 외부 표면이 밝게 빛나게 되는 실리콘 고무접점스위치에 관한 것이다.The present invention relates to a push switch used in a telephone or other electronic products, in particular, a silicon rubber contact switch in which the outer surface of the switch shines brightly so that it can be distinguished at night as the LED lamp is built in. It is about.
고안의 배경Background of the devise
전화기의 외관을 미려하게 하고, 또한 야간에 다수의 기능키가 설치된 키패드의 각각의 키를 눌러줄 때 이들 키값이 정확하게 눌려졌는지를 확인할 수 있도록 하기 위하여 전화기 내부에 조명장치를 사용하고 있는 추세이다. 특히 전화기에서는 키패드에 누름방식의 키로서 사용되는 실리콘 고무접점스위치 내부에 LED램프를 내장하여 소정 키를 눌러주게 되면 키부분이 밝게 빛나도록 구성되어 사용되고 있으며, 이것은 전화기 뿐만 아니라 키를 사용하는 전자제품의 키부분에 다양하게 사용되고 있는 헝편이다.The trend is to use a lighting device inside the phone to make the appearance of the phone beautiful and to check whether the values of these keys are pressed correctly when each key of the keypad equipped with a plurality of function keys is pressed at night. In particular, the phone has a built-in LED lamp inside the silicone rubber contact switch, which is used as a key of the keypad, and the key part shines brightly when a predetermined key is pressed. This is used for electronic products using keys as well as phones. It is used in various parts of the key part.
그러나 종래에는 이러한 형태의 실리콘 고무접점스위치 어셈블리는 스위치 내부에 내장된 LED램프가 그대로 스위치의 누름패드 외부로 비치게 되므로 외부에서 스위치의 누름패드 상부면을 보면 누름패드 상부면의 위치에 따라서 LED가 위치한 패드면 중앙부분은 밝게 빛나는 반면에 패드면 가장자리로 갈수록 어두워지게 되어 외관상 보기가 미려하지 않을 뿐만 아니라 누름패드 상부면에 표시된 문자를 인식하지 못하는 문제가 있었던 것이다.However, in the conventional silicone rubber contact switch assembly of this type, since the LED lamp embedded in the switch is reflected to the outside of the push pad of the switch as it is, when the external view of the top of the push pad of the switch, the LED is positioned according to the position of the top of the push pad. While the center of the pad surface is brightly shining, it becomes darker toward the edge of the pad surface, which not only makes the appearance more beautiful but also does not recognize the characters displayed on the upper surface of the pressing pad.
고안의 목적 및 요약Purpose and Summary of the Invention
본 고안은 이러한 종래의 LED램프 내장형 실리콘 고무접점스위치 어셈블리의 단점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 LED램프상부에 상부측을 향하여 돌출된 볼록렌즈형태의 방사광 분산부를 구성하여 LED램프로부터 나온 방사광이 상기 방사광분산부를 통과하면서 반투명 누름패드 상부면에 고르게 분산되도록 하여 외관상 반투명누름패드의 밝기가 전체면에 걸쳐서 일정하도록 구성된 LED램프내장형 실리콘 고무접점스위치를 제공하는데 있다.The present invention was devised to solve the disadvantages of the conventional silicon LED contact switch assembly built-in LED lamp, the object of the present invention is to form a convex lens-type radiation light emitting portion protruding toward the upper side on the LED lamp LED lamp It is to provide an LED lamp-embedded silicon rubber contact switch configured so that the light emitted from the evenly distributed on the upper surface of the translucent push pad while passing through the radiation dispersion portion, the brightness of the translucent push pad is uniform throughout the entire surface.
고안의 구체적 실시예에 대한 설명Description of Specific Embodiments of the Invention
본 고안을 첨부도면을 참조하여 종래의 기술과 대비하여 설명하면 다음과 같다.The present invention will be described with reference to the accompanying drawings in contrast to the prior art.
제1도는 종래의 LED램프를 내장한 실리콘 고무접점스위치의 단면도로서, 도전성 실리콘 고무접점부(4), 반투명누름패드(3), 상기 반투명 누름패드(3)면을 누름에 따라 도전성 실리콘 고무접점부(4)와 접촉되는 PCB접점기판(1) 및 실리콘 고무접점부(4)와 상기 PCB접점기판(1)이 닿게 되면 켜지고, 떨어지면 꺼지게 되는 PCB접점기판(1)상에 설치된 LED램프(2)로 구성되어 있다.1 is a cross-sectional view of a silicone rubber contact switch incorporating a conventional LED lamp, the conductive silicone rubber contact by pressing the surface of the conductive silicone rubber contact portion 4, the translucent push pad (3), the translucent push pad (3). LED lamp (2) installed on the PCB contact substrate (1) to be in contact with the part (4) and the silicon rubber contact part (4) and the PCB contact substrate (1) is turned on, and to fall off when the PCB contact substrate (1) is contacted It consists of).
따라서, 반투명 누름패드(3), 상부면을 누르게 되면 도전성 실리콘 고무접점부(4)가 PCB접점기판(1)에 닿아서 LED램프(2)가 켜지게 된다. LED램프(2)로부터 방사되는 광은 중간매개체없이 직접 반투명누름패드(3)를 통하여 스위치 외부로 방사되는 것이다.Accordingly, when the translucent push pad 3 and the upper surface are pressed, the conductive silicon rubber contact portion 4 contacts the PCB contact substrate 1 so that the LED lamp 2 is turned on. Light emitted from the LED lamp 2 is emitted out of the switch directly through the translucent push pad 3 without an intermediate.
이와 같이, LED램프(2)로부터의 방사광이 그대로 누름패드(3) 상부면을 비치게 되므로 해서 누름패드(3) 상부면의 중앙부분은 밝게 조명되는 반면에, 누름패드(3)상부면의 가장자리부분으로 갈수록 어두워지게 되기때문에, 누름패드(3) 상부면 전체로 볼 때 일정한 밝기를 유지할 수 없는 것이다.As such, since the light emitted from the LED lamp 2 reflects the upper surface of the pressing pad 3, the center portion of the upper surface of the pressing pad 3 is brightly illuminated, while the upper surface of the upper surface of the pressing pad 3 is illuminated. Because it becomes darker toward the edge portion, it is not possible to maintain a constant brightness when viewed throughout the upper surface of the push pad (3).
그러나 본 고안은 제2도에 도시된 바와 같이, PCB접점기판(1) PCB접점기판(1) 상에 설치된 LED램프(2), LED램프(2)로부터 일정거리 이격되어 상기 LED램프(2)를 감싸는 반투명누름패드(3) 및 PCB접점기판(1)으로부터 일정거리 이격된 상부의 반투명 누름패드(3)에 부착된 도전성 실리콘 고무접점부(4)로 구성된 LED램프내장형 실리콘 고무접점스위치 어셈블리에 있어서, 반투명누름패드(3)의 상부면과 상기 LED램프(2) 사이의 누름패드(3) 내부중간에 수평으로 걸쳐져서 형성된 볼록렌즈 형태의 방사광 분사부(5)를 구비하였다.However, the present invention, as shown in Figure 2, the PCB contact substrate (1) the LED lamp (2) installed on the PCB contact substrate (1), a predetermined distance from the LED lamp (2) the LED lamp (2) To the LED lamp-embedded silicon rubber contact switch assembly consisting of a semi-transparent push pad (3) surrounding the encapsulation and a conductive silicon rubber contact portion (4) attached to the upper translucent push pad (3) at a distance from the PCB contact substrate (1) The light emitting part 5 of the convex lens formed horizontally across the upper surface of the translucent push pad 3 and the inside of the push pad 3 between the said LED lamp 2 was provided.
따라서 상기와 같이 구성된 본 고안의 LED내장형 실리콘 고무접점스위치어셈블리의 반투명 누름패드(3)를 눌러주게 되면 전도성 실리콘 고무접점부(4)와 상기 PCB접점기판(1)이 연결되어서 LED램프(2)가 온된다.Therefore, when the semi-transparent pressing pad 3 of the LED-embedded silicon rubber contact switch assembly of the present invention configured as described above is pressed, the conductive silicon rubber contact portion 4 and the PCB contact substrate 1 are connected to the LED lamp 2. Comes on.
따라서 LED램프(4)로부터 출력되는 방사광은 방사광 분산부(5)를 통과함에 따라 반투명누름패드(3) 상부면상에 방사광을 고르게 분산시켜 누름패드(3) 상부면에 걸쳐서 일정한 밝기를 유지하게 되는 것이다.Therefore, the emitted light output from the LED lamp 4 is evenly distributed over the upper surface of the semi-transparent pressing pad 3 as it passes through the radiation scattering portion 5 to maintain a constant brightness across the upper surface of the pressing pad (3) will be.
상기 반투명누름패드(3)는 종래 사용되는 기술에 의하여 용이하게 구성할 수 있음을 본 고안이 속하는 분야의 당업자에게는 명백한 것이다.It will be apparent to those skilled in the art to which the present invention belongs that the translucent push pad 3 can be easily configured by conventionally used techniques.
상기한 바와 같이, 본 고안은 LED램프(2)와 반투명누름패드(3) 상부면 사이에 볼록렌즈형태의 방사광분산부(5)를 설치하여 LED램프로부터 방출되는 방사광의 밝기를 반투명 누름패드 상부면 전체에 걸쳐서 고르게 유지할 수 있어서, 이를 야간에 실별할 수 있는 조명이 요구되는 전화기, 오디오세트 또는 기타 전자제품의 키 부분으로 사용할 때에 미려한 외관과 함께 유용성을 제공할 수 있는 것이다.As described above, the present invention is installed between the LED lamp 2 and the upper surface of the semi-transparent press pad (3) convex lens-type radiation scattering portion 5 to the top of the translucent push pad brightness of the light emitted from the LED lamp It can be maintained evenly across the surface, providing usefulness with a beautiful appearance when used as a key part of a telephone, audio set or other electronic product that requires night vision.
본 고안은 기재된 구체예에 대해서만 상세히 설명되었지만 본 고안의 사상과 범위내에서 변형이나 변경할 수 있음은 본 고안이 속하는 분야의 당업자에게는 명백한 것이며, 그러한 변형이나 변경은 첨부한 실용신안등록청구범위에 속한다 할 것이다.Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that the present invention may be modified or changed within the spirit and scope of the present invention, and such modifications and changes are included in the appended claims of utility model registration. something to do.
