휴대 단말기에 형성되는 키패드의 돔 스위치{Dome switch of keypad form mobile phone}Dome switch of keypad formed in the mobile terminal {Dome switch of keypad form mobile phone}

본 고안은 휴대 단말기에 형성되는 키패드의 돔 스위치에 관한 것으로, 상세하게는 통상의 휴대 단말기에 형성되는 키패드에 결합하여, 휴대 단말기에 신호를 입력하는 돔 스위치의 구성이, 다수개의 절곡부로 구성된 빛확산부를 형성하여, 적은 개수의 조명등으로 키패드의 전체에 균일하게 조명될 수 있도록 한 것이다.The present invention relates to a dome switch of a keypad formed in a portable terminal, and in detail, a dome switch configured to be coupled to a keypad formed in a conventional portable terminal and input a signal to the portable terminal comprises a light composed of a plurality of bent portions. By forming a diffusion part, it is possible to uniformly illuminate the entire keypad with a small number of lights.

일반적으로 사용되는 휴대 단말기의 경우, 단말기의 신호 발생을 위한 장치로서 키패드가 있으며, 이러한 키패드는 접점을 갖는 인쇄회로기판 위에 위치한 상태로, 단말기의 프런트 하우징에 마련된 홀에 끼워져 키의 일부분만 하우징 외 측으로 돌출되는 구조로 조립된다.In general, a portable terminal includes a keypad as a device for generating a signal of the terminal. The keypad is located on a printed circuit board having a contact point, and is inserted into a hole provided in the front housing of the terminal so that only a part of the key is located outside the housing. Assembled in a structure that protrudes to the side.

상기와 같은 휴대 단말기의 경우 단말기의 키패드와 인쇄회로기판(PCB) 사이에는 탄성력과 복원력을 갖는 돔 스위치가 위치하며, 이 돔 스위치는 키패드를 구성하는 키 동작에 의해 인쇄회로기판에 마련된 접점과 접촉하여 신호를 발생시키는 것이다.In the case of the portable terminal, a dome switch having elasticity and restoring force is positioned between the keypad of the terminal and the printed circuit board (PCB), and the dome switch contacts the contact provided on the printed circuit board by a key operation constituting the keypad. To generate a signal.

이러한 키패드를 구성하는 각각의 버튼에는 숫자와 한글 및 영문과 이미지가 표현되어 있어 사용자가 지정된 신호를 입력할 수 있지만, 상기의 버튼에 형성되는 이미지의 굵기가 1mm를 넘지 않는 정도로 매우 작게 각인되어 있어, 사용자가 버튼의 이미지를 쉽게 확인할 수 있도록 하기 위해, 단말기 하우징에 형성된 조명등으로 버튼의 이미지로 투영되어, 버튼에 각인된 이미지를 쉽게 인식하도록 하고 있다.Numerals, Korean, English and images are displayed on each button constituting the keypad so that a user can input a designated signal, but the size of the image formed on the button is engraved so small that it does not exceed 1mm. In order to make it easy for the user to check the image of the button, it is projected to the image of the button by the illumination lamp formed in the terminal housing, so that the image imprinted on the button can be easily recognized.

그러나 상기와 같은 종래의 휴대 단말기는, 버튼의 이미지 조명을 제공하는 방법이 휴대 단말기에 형성되는 조명등만을 사용하고 있어, 버튼으로 발산되는 조명등의 조도는 강하지만, 조명등에 가까운 곳은 그 빛이 밝고 조명등과 멀리 있는 곳은 어두운 문제가 발생하므로, 키패드의 균일한 조명을 위해서는 많은 조명등 개수가 필요하여, 작업의 번거로움과 제작비 상승으로 인하여 경쟁력이 약화하는 문제점이 있었다.However, in the conventional mobile terminal as described above, the method of providing the image illumination of the button uses only the illumination lamp formed in the mobile terminal, and the illuminance of the illumination emitted by the button is strong, but the light is bright near the illumination lamp. Since the dark place is far away from the lamp, a number of lamps are required for uniform illumination of the keypad, and there is a problem that the competitiveness is weakened due to the cumbersome work and the increase in production cost.

본 고안은 상기의 문제점을 감안하여 통상의 휴대 단말기에 형성된 돔 스위치의 구성에서, 키패드 저면에 결합하여 인쇄회로기판(PCB)에 신호를 입력하는 돔 스위치를 개선한 것으로, 상기의 돔 스위치에 빛을 확산시키는 다수개의 절곡부를 가지는 빛확산부를 형성하여, 인쇄회로기판에 형성되는 소수의 L.E.D나 다이오드 전구에서 발산되는 빛이 키패드에 균일하게 밝게 조명될 수 있도록 한 것으로, 첨부된 도면에 의해 상세하게 설명하면 다음과 같다.The present invention improves the dome switch for inputting a signal to a printed circuit board (PCB) by coupling to the bottom of the keypad in the configuration of a dome switch formed in a conventional portable terminal in view of the above problems, By forming a light diffusing portion having a plurality of bent portions to diffuse the light, the light emitted from a small number of LEDs or diode bulbs formed on the printed circuit board can be uniformly brightly illuminated on the keypad in detail by the accompanying drawings The explanation is as follows.

한글과 영문자 및 숫자로 구성된 이미지(1)가 각인된 다수개의 버튼(2)이 형성된 키패드(3)와, L.E.D. 또는 다이오드 전구와 같은 조명등(4)과 접점 누름부(5)를 가지는 인쇄회로기판(PCB)(6)과, 상기 인쇄회로기판(6)을 동작하는 돌부(7)가 형성된 돔 스위치(8)를 결합하여 휴대 단말기(9)에 신호를 입력하는 돔 스위치(8)의 구성에서, 상기의 돔 스위치(8)의 구성이, 다수개의 절곡부(11)로 구성된 빛확산부(12)로 형성된 것이다.A keypad (3) having a plurality of buttons (2) imprinted with an image (1) composed of Korean, English letters and numbers, and L.E.D. Or a dome switch 8 having a printed circuit board (PCB) 6 having a lighting lamp 4 such as a diode bulb and a contact pressing part 5, and a protrusion 7 for operating the printed circuit board 6. In the configuration of the dome switch 8 for inputting a signal to the portable terminal 9 by combining the above, the configuration of the dome switch 8 is formed of a light diffusing portion 12 composed of a plurality of bent portions 11. will be.

이와 같이 다수개의 절곡부(11)로 구성된 빛확산부(12)를 가지는 돔 스위치(8)를 키패드(3)에 결합한 휴대 단말기(9)의 사용은 다음과 같다.The use of the portable terminal 9 in which the dome switch 8 having the light diffusing portion 12 composed of a plurality of bends 11 is coupled to the keypad 3 is as follows.

본 고안의 돔 스위치(8)의 사용은, 휴대 단말기(9)에 형성된 키패드(3)의 버튼(2)을 이용하여 휴대 단말기(9)에 신호를 입력하면, 가압 되는 버튼(2)의 저면에 위치한 돔 스위치(8)가 동일하게 가압 되어, 돔 스위치(8)에 형성된 돌부(7)가 저면에 위치하는 인쇄회로기판(6)의 누름부(5)를 가압하여, 휴대 단말기(9)에 신호가 입력되는 것으로, 돔 스위치(8)의 사용은 종래의 휴대 단말기의 사용과 동일하다.The use of the dome switch 8 of the present invention is based on the bottom of the button 2 that is pressed when a signal is input to the mobile terminal 9 using the button 2 of the keypad 3 formed on the mobile terminal 9. The dome switch 8 located at the same position is pressed equally, and the pressing portion 5 of the printed circuit board 6 at the bottom face of the protrusion 7 formed at the dome switch 8 is pressed to carry out the portable terminal 9. The signal is input to the dome switch 8, and the use of the dome switch 8 is the same as that of the conventional portable terminal.

본 고안은 사용자가 휴대 단말기(9)를 사용하기 위해 폴더를 개방하거나, 또는 휴대 단말기(9)에 신호가 수신되면, 인쇄회로기판(6)에 형성된 L.E.D 또는 다이오드로 구성된 조명등(4)이 둠 스위치(8)의 측면에 위치하고 있어, 조명등(4)이 첨부된 도 4와 같이 빛이 확산하여 외부로 발산되는 것이다.According to the present invention, when a user opens a folder for using the portable terminal 9, or receives a signal from the portable terminal 9, an illumination lamp 4 composed of an LED or a diode formed on the printed circuit board 6 is placed. Located on the side of the switch 8, as shown in Figure 4 attached to the lamp 4 is to diffuse the light to the outside.

상기와 같이 조명등(4)에서 점등된 빛이 버튼(2)의 각인된 이미지(1) 외부로 발산될 때, 돔 스위치(8)의 빛확산부(12)가 빛을 확산하여 외부로 발산되는 것이며, 각각의 버튼 아래로 형성된 빛확산부(12)가 균일하게 빛을 확산시켜, 키패드(3)가 전체적으로 균일하게 외부로 빛을 발하는 조명을 갖게 되는 것이다.When the light turned on from the lamp 4 is emitted to the outside of the imprinted image 1 of the button 2 as described above, the light diffuser 12 of the dome switch 8 diffuses the light to the outside. The light diffusing part 12 formed under each button diffuses the light uniformly, so that the keypad 3 has an illumination that emits light uniformly as a whole.

이러한 본 고안의 사용은 휴대 단말기(9)에 장식을 위해 키패드에 별도로 형성하는 여러 개의 유색 조명등의 사용하는 경우, 다양한 조명이 연출되는 것이다.The use of the present invention is to produce a variety of lights when using a plurality of colored lights separately formed on the keypad for decoration on the mobile terminal (9).

본 고안에서 돔 스위치(8)의 빛확산부(12)는, 도 5에 표현된 바와 같이 빛을 확산시키는 절곡부(11)의 형태를 삼각, 사각, 또는 원형과 같이 다양하게 실시할 수 있는 것으로, 절곡부(11)의 각도와 절곡부(11)의 개수 및 절곡부(11)의 대소(大小)로 인해 다양한 행태로 사용될 수 있는 것이다.In the present invention, the light diffusing part 12 of the dome switch 8 may implement various shapes of the bent part 11 for diffusing light, such as triangular, square, or circular, as shown in FIG. 5. By the angle of the bent portion 11 and the number of the bent portion 11 and the size of the bent portion (11) can be used in various ways.

상기에서 상세하게 설명한 바와 같이, 다수개의 절곡부(11)를 가지는 빛확산부(12)가 형성된 투명필름으로 구성된 돔 스위치(8)를 결합한 휴대 단말기(9)의 사용은, 인쇄회로기판(6)에 형성된 조명등(4)이 돔 스위치(8)의 측면으로 위치하고 조명되어 키패드(3)를 밝게 하는 효과가 있는 것이다.As described in detail above, the use of the portable terminal 9 in which the dome switch 8 made of a transparent film having the light diffusing portion 12 having the plurality of bent portions 11 is combined is a printed circuit board 6. Illumination (4) formed in the) is located on the side of the dome switch (8) is illuminated is effective to brighten the keypad (3).

상기와 같은 효과는 둠 스위치(8) 측면이나 중심에 위치하는 조명등(4)이, 돔 스위치(8)의 빛확산부(12)를 통해 키패드(3) 전체에 균일한 조명을 제공하는 효과를 가지므로, 이러한 돔 스위치(8)의 사용은 인쇄회로기판(6)을 가지는 컴퓨터, 계산기, PDA, MP3 등과 같이, 키패드(3)를 이용하여 신호를 입력하는 전자기기에 활용할 수 있는 것이다.As described above, the illumination lamp 4 located at the side or the center of the Doom switch 8 has an effect of providing uniform illumination to the entire keypad 3 through the light diffuser 12 of the dome switch 8. Therefore, the use of the dome switch 8 can be utilized for an electronic device that inputs a signal using the keypad 3, such as a computer, a calculator, a PDA, and an MP3 having the printed circuit board 6.
