[발명의 상세한 설명]Detailed description of the invention

[본 발명의 배경]Background of the Invention

1. 발명의 분야1. Field of Invention

본 발명은 전자휴대용 컴퓨터, 디지탈시계, 워드프로세서, 퍼스날컴퓨터 9 비디오 디스크장치, 오디오기구, 누름단추식 전화기등과 같은 다양한 전자장치용 키이보오드와 같은 스위칭장치에 있어서 프린트회로판 즉, LSI칩등과 같은 전극사이에서 상호연결로 사용되는 접점고무의 구조에 관한 것이다.The present invention relates to a switching device such as a key board for various electronic devices such as an electronic portable computer, a digital clock, a word processor, a personal computer 9 video disk device, an audio device, a push button telephone, and the like. A structure of contact rubber used as an interconnect between electrodes.

2.선행기술2. Advanced technology

전도부가 다량의 전기 절연고무로 카아본파우더를 분산하므로써 만들어진 전기전도고무로 구성된 접점고무는 접점고무가 전기전도잉크등으로 프린트된 전자절연고무와 함께 가황(vulcanisation)하에서 결합된다는 것은 공지이다.It is known that the contact rubber, which consists of conductive rubber made by dispersing the carbon powder with a large amount of electrically insulating rubber, is bonded under vulcanisation together with the electronic insulating rubber printed by the conductive ink.

접점고무는 스위칭 키이보오드등과 같은 것의 키이작동용 조종기 키이에 사용되머 키이입력을 달성키 위하여 인지터치용 키이꼭대기와 통합하여 배열된다.The contact rubber is used for keying manipulator keys, such as switching key boards, etc., arranged in combination with the key top for cognitive touch to achieve key input.

키이꼭대기 위에 그러한 인지터치가 있을 때 인간의 손가락의 지방 또는 유기산 에스테르는 키이꼭대기로 이전될 것이다.When such a cognitive touch is on the top, the fat or organic acid ester of the human finger will be transferred to the top.

그래서 키이꼭대기의 물질을 통해 관통되고 연장기간이 경과된 후 접점고무에 도달하여 그것을 커버하도록 그 위에 위치되어 그것에 의해 껍질벗기기 접점부재와 함께 접점고무의 접촉시 접촉저항을 증가시킨다.It is thus penetrated through the material of the key top and placed over it to reach and cover the contact rubber after an extended period of time, thereby increasing the contact resistance upon contact with the contact rubber with the peeling contact member.

역시 키이꼭대기의 수지재료에 포함된 오일과 저분자중량 실록산은 분리되며 전도부에 놓여지며 그것에 의해 더욱더 접촉저항의 증가를 용이하게 하며 극한의 경우에 전기전도까지 방해할 수 있다.The oil and low molecular weight siloxane contained in the key top resin material are also separated and placed in the conducting portion, thereby facilitating further increase in contact resistance and, in extreme cases, even disturb electrical conduction.

[본 발명의 요약]Summary of the Invention

본 발명에 따라서 전도부와 키이꼭대기의 수지물체사이에서 오일저항을 삽입시키므로써 접점고무의 전도부에 인간의 손가락으로부더 실록산 및 지방 그리고 에스테르와 같은 절연물질의 축적을 막는 것이 심사숙고 되어진다.According to the present invention, it is contemplated to prevent the accumulation of insulating materials such as siloxane, fat, and ester with the human finger by inserting an oil resistance between the conductive portion and the resin object of the key top.

이렇게 발명은 전도와 키이꼭대기의 수지보디사이에 끼워진 오일저항층을 정돈하도록 제안된다.Thus the invention is proposed to arrange the oil resistant layer sandwiched between the conduction and the resin body of the key top.

키이보오드가 유지성 안개로 대기가 오염되는 공장 또는 조리실등에 위치된다할지라도 그러한 오일저항삽입층의 상호작용에 의해 환경 또는 인간 손가락으로부터 전기절연물질의 축적 또는 관통이 방해받는다.Even if the key board is located in a factory or a cooking room where the air is contaminated with a maintenance fog, the interaction of such an oil resistance interlayer prevents the accumulation or penetration of electrical insulating material from the environment or human fingers.

오일저항층을 상호작용시키기 위하여 측정이 고려되며 여기서 수지필름이 키이꼭대기의 절연수지 보디와 전자전도고무층사이에 위치하며 여기서 상기한 수지필름은 두 전기전도고무층사이에 배열되며 오일저항고무층은 전기절연 키이꼭대기보디등을 걸쳐 위치된다.Measurements are considered to interact with the oil resistant layer, where a resin film is placed between the insulating resin body at the top of the key and the electrically conductive rubber layer, wherein the resin film is arranged between the two electrically conductive rubber layers and the oil resistant rubber layer is electrically insulated. The key is located across the top body.

만약 오일저항층이 두 전기전도고무층사이에 위치한다면 오직 이러한 전기전도층이 분리되어 주조되며 후에 통합체를 형성하기위하여 접착제와 함께 접점고무보디위에 결합된다.If an oil resistant layer is located between two electrically conductive rubber layers, only these electrically conductive layers are cast separately and later bonded onto the contact rubber body with adhesive to form an integrated body.

이것은 합리적이다.This is reasonable.

왜냐하면 접점고무보디위의 전기전도층의 접착작용이 이러한 용이한 작용을 허락하도록 전기전도층의 표면이 위 또는 아래에 있던지 상관없이 영향받을 수 있다.Because the adhesion of the conductive layer on the contact rubber body can be influenced regardless of whether the surface of the conductive layer is above or below to allow this easy action.

[언급된 실시예의 상세한 설명]Detailed description of the embodiments mentioned

제 1 도에 있어서, 오일저항층(3,4)이 상호위치하에서 바닥면에 전자전도부(2)의 층을 지니는 키이브오드의 키이꼭대기는 프린트회로판 서브 스트레이트(5)위에 전극이 있다.In Fig. 1, the key top of the kibe-odd having the layer of the electron conducting portion 2 on the bottom surface of the oil resistance layers 3 and 4 is located on the printed circuit board sub straight 5.

키이꼭대기(1)는 절연고무를 주조하므로써 만들어진다.The tall top 1 is made by casting insulating rubber.

아래를 향하여 돌출하는 키이꼭대기(1)의 언더사이드에 오일저항층(3)은 프린시펄 실록산 폴리머 체인등과 같은 것에 할로겐 또는 유기화합물이 그라아프되는 플루오로 고무, NBR, 플루오로화물, 아크릴고무, 에프클로로하이드린고무등과 같은 비가황(non-vulcanized) 실리콘으로부터 파생된 오일저항물질로 프린팅에 의해 위치된다.The oil resistant layer 3 at the underside of the key top 1 protruding downwards is composed of fluororubber, NBR, fluoride, acrylic, which is grafted with a halogen or an organic compound, such as a principal siloxane polymer chain or the like. It is located by printing with oil-resistant materials derived from non-vulcanized silicones such as rubber, echlorohydrin rubber and the like.

물론 그들 사이에서 그것을 삽입하므로써 오일저항층을 상호작용하게 하는 것이 가능하다.Of course it is possible to make the oil resistant layer interact by inserting it between them.

제 2 도에서 본 발명의 다른 실시예가 설명되며 키이꼭대기 보디(11)의 바닥면은 전기전도층(14), 오일저항층(13) 및 다른 전기전도층(12)으로 만들어진다. 가장 내부의 전기전도고무층(14), 수지필름(13)과 가장외부의 전기전도고무층(12)은 필름의 형태로 각각 분리되어 만들어지며 이것으로부터 각 시이트(sheet), 피이스(pieces)는 예정된 형태로 그것들을 구멍을 뚫음으로써 절단되며 이것은 계속하여 상기한 접착제에 의해 키이꼭대기 보디(1)의 바닥표면에 결합된다.Another embodiment of the invention is illustrated in FIG. 2 and the bottom surface of the key top body 11 is made of an electrically conductive layer 14, an oil resistant layer 13 and another electrically conductive layer 12. The innermost conductive rubber layer 14, the resin film 13 and the outermost conductive rubber layer 12 are made separately in the form of a film, from which sheets and pieces are arranged. It is cut by punching them into a shape which is subsequently joined to the bottom surface of the keytop body 1 by the above-mentioned adhesive.
