To this end, holes 11 are drilled on the surfaces of the lower housing 10 at positions corresponding to the metal keys 43, respectively.

이러한 메탈키(43)들은 금속플레이트를 가공하여 제작되며, 여기에는 숫자 또는 문자 식별이 가능하도록 가공된다. 즉, 메탈키(43)들에는 레이져 가공, 프레스 및 에칭방식을 통해 숫자 또는 문자 식별부(44)가 상하 두께방향으로 관통하도록 가공된다.These metal keys 43 are manufactured by processing a metal plate, which is machined to enable identification of numbers or letters. That is, the metal keys 43 are processed so that the numeral or letter identification unit 44 penetrates in the vertical direction through laser processing, pressing, and etching.

그리고 메탈키(43)의 숫자 또는 문자 식별부(44)에는 광투과성이 우수한 합성수지(45)가 몰딩 처리되어 있다. 이러한 합성수지는 광투과성이 우수한 에폭시계열, 우레탄, 실리콘, 투명 아크릴 등을 적용할 수 있다. 이와 같이, 합성수지(45)를 숫자 또는 문자 식별부(44)에 몰딩 처리한 것은, 숫자 또는 문자 식별부(44)에 이물질이 끼는 것을 방지하며, 하부 하우징(10) 내부에서 조명되는 빛(일명, 백라이팅)이 메탈키(43)를 투과하여 외부로 비춰지도록 하기 위함이다. {본 발명의 실시 예에서 숫자 또는 문자 식별부(44)에는 광투과성이 우수한 에폭시계열 수지로 몰딩 처리하였는데, 앞서 기술한 바와 같이 광투과성이 우수한 우레탄, 실리콘, 투명 아크릴 등의 합성수지를 통해서도 몰딩처리가 가능하다.}In addition, a synthetic resin 45 having excellent light transmittance is molded in the numeric or letter identification unit 44 of the metal key 43. Such synthetic resins may be applied to the epoxy series, urethane, silicone, transparent acrylic and the like excellent in light transmittance. As such, molding the synthetic resin 45 on the number or letter identification unit 44 prevents foreign substances from being caught in the number or letter identification unit 44, and the light illuminated in the lower housing 10. , Backlighting) is transmitted through the metal key 43 so as to be reflected to the outside. {In the embodiment of the present invention, the number or letter identification unit 44 is molded with an epoxy-based resin having excellent light transmittance, and as described above, the molding process is also performed through synthetic resin such as urethane, silicone, and transparent acrylic having excellent light transmittance. Is possible.}

또한, 메탈키(43)들은 금속 플레이트를 통해 가공한 것으로 기술하였는데, 이것은 스테인리스 스틸, 알루미늄 합금, 티타늄 합금, 동 합금 등과 같은 다양한 금속 플레이트를 재료를 가공하여 제작이 가능하다.In addition, the metal keys 43 are described as processed through a metal plate, which can be manufactured by processing various metal plates such as stainless steel, aluminum alloy, titanium alloy, copper alloy, and the like.

이와 같이, 메탈키(43) 자체가 금속(스틸)으로 이루어지기 때문에, 자연스러운 메탈감과 거울효과를 사실성 있게 표현할 수 있으며, 증착과 착색 또는 도금을 이용한 다양한 색상구현이 가능하다. 그리고 헤어라인 및 다양한 패턴구현이 가능하며 키 형태를 자유자재로 제작 구현할 수 있다. 또한, 메탈키(43)는 색상의 변색이 없고 처음의 고급스러움이 지속적으로 유지되어 내구성 역시 월등하다.As such, since the metal key 43 itself is made of metal (steel), it is possible to realistically express a natural metal feeling and a mirror effect, and various colors may be implemented using deposition, coloring, or plating. And hairline and various patterns can be implemented, and the key shape can be freely implemented. In addition, the metal key 43 has no discoloration of color and the durability of the first luxury is continuously maintained.

In addition, since the metal key 43 is manufactured by the laser processing method and the etching method, a specific tool is not required, and thus, mass production is possible, and the response force according to the design change is also excellent.

다음에는 이와 같이 구성된 본 발명에 따른 키패드 조립체의 작동 및 이에 따른 효과를 설명한다.Next, the operation of the keypad assembly according to the present invention configured as described above and the effects thereof will be described.

먼저, 상부 하우징(20)을 개방하면 하부 하우징(10) 내부의 백라이팅 조명(미도시)이 구동되며, 여기에서 발생된 빛은 키패드(41)와 메탈키(43)의 숫자 또는문자 식별부(44)를 통해 외부로 비춰진다(도 4참조).First, when the upper housing 20 is opened, backlighting illumination (not shown) inside the lower housing 10 is driven, and the light generated therein is a numeric or letter identification unit of the keypad 41 and the metal key 43. 44) to the outside (see FIG. 4).

이와 같이, 상부 하우징(20)을 개방한 상태에서 메탈키(43)의 숫자 또는 문자 식별부(44)를 확인하면서 이를 손끝으로 누르면, 키패드(41)의 돌기(42)에 의해 돔 스위치(70)의 가동접점(71)이 탄성 변형되면서 아래 방향으로 눌려진다. 이에 따라 돔 스위치(70)의 가동접점(71)과 인쇄회로기판(60)의 고정접점(61)이 전기적으로 접촉됨으로써, 휴대폰을 작동시킬 수 있는 신호가 입력된다.Thus, pressing the fingertips while checking the numeric or letter identification portion 44 of the metal key 43 in the state in which the upper housing 20 is opened, the dome switch 70 by the projection 42 of the keypad 41. The movable contact 71 of) is pressed downward while being elastically deformed. Accordingly, the movable contact 71 of the dome switch 70 and the fixed contact 61 of the printed circuit board 60 are electrically contacted, so that a signal for operating the mobile phone is input.

그리고 신호를 입력시킨 후 누르고 있던 메탈키(43)에서 손을 떼면, 돔 스위치(70) 자체의 탄성 복원력에 의해 가동접점(71)이 상측으로 복원됨과 동시에 메탈키(43) 역시 상측으로 올라온다.When the signal is input and then released from the metal key 43 held down, the movable contact 71 is restored upward by the elastic restoring force of the dome switch 70 itself, and the metal key 43 also rises upward.

이와 같이, 손끝으로 눌러 작동시키는 메탈키(43)들이 금속으로 제작됨과 동시에 여기에는 숫자 또는 문자 식별부(44)가 메탈키(43) 자체를 관통 가공하여 구성되어 있기 때문에 반복적으로 사용하더라도 변형이 발생되지 않는다. 또한, 숫자 또는 문자 식별부(44)에는 광투과성의 합성수지(45)가 몰딩 처리되어 있기 때문에, 이물질이 끼는 것이 방지됨은 물론이며 하부 하우징(10)의 백라이팅 역시 원활하게 투과된다.As described above, since the metal keys 43 operated by pressing at the fingertips are made of metal, the number or letter identification unit 44 is formed by penetrating the metal keys 43 itself, so that the deformation is repeated even when used repeatedly. It does not occur. In addition, since the light transmissive synthetic resin 45 is molded in the number or letter identification unit 44, foreign matter is prevented from being caught, as well as backlighting of the lower housing 10 is also smoothly transmitted.

이상에서 상세히 설명한 바와 같이; 본 발명에 따른 휴대폰용 키패드 조립체에 의하면, 돔 스위치들을 덮도록 배치되며 가동접점들과 대응하는 위치에 돌기들이 마련된 키패드와, 돌기들과 대응하는 키패드의 상부에 각각 부착되어 하우징의 표면에서 일정높이 돌출되며 숫자 또는 문자 식별부가 가공된 금속재질의 메탈키들을 구비하고 있다.As described in detail above; According to the keypad assembly for a mobile phone according to the present invention, a keypad disposed to cover the dome switches and provided with protrusions at positions corresponding to the movable contacts, and attached to an upper portion of the keypad corresponding to the protrusions, respectively, has a predetermined height at the surface of the housing. It has a protruding metal key with a machined number or letter identification.

따라서 메탈키들을 반복적으로 사용하더라도 이것이 변형되거나 변색되지 않고, 숫자 또는 문자 식별부가 지워지지 않는 장점이 있다. 그리고 숫자 또는 문자 식별부를 메탈키 자체를 관통 가공한 후 여기에 광투과성이 우수한 에폭시계열, 우레탄, 실리콘, 투명 아크릴 등의 합성수지를 몰딩 처리하였기 때문에, 이물질이 끼어 오염됨을 방지하며 하우징 내부에서 조사된 백라이팅 역시 용이하게 투과되는 장점이 있다. 또한, 금속으로 제작된 메탈키들의 전면부가 하우징 표면으로 노출되기 때문에, 휴대폰의 이미지를 보다 강한 메탈 분위기로 이끌 수 있으며 이것에 의해 제품 구매력 역시 높일 수 있는 작용효과가 있다.Therefore, even when the metal keys are repeatedly used, they are not deformed or discolored, and the numbers or letters are not erased. In addition, after processing the numeric or letter identification part through the metal key itself, the synthetic resin such as epoxy series, urethane, silicone, transparent acrylic, etc., which has excellent light transmittance, is molded, thereby preventing contamination due to foreign substances. Backlighting also has the advantage of being easily transmitted. In addition, since the front portion of the metal keys made of metal is exposed to the housing surface, it can lead to an image of the mobile phone to a stronger metal atmosphere, thereby increasing the purchasing power of the product.
