본 발명은 핸드폰에서 발생되는 전자파를 차폐하기 위한 케이스에 관한 것으로, 특히 전자파 차폐능이 우수한 황산동(CuSO4)이나 금(Au) 또는 은(Ag)을 메쉬 형태로 직조한 차폐층과 투명성을 갖는 투명 시트를 합지하여 핸드폰의 케이스를 제공하여 각종 핸드폰에서 발생되는 전자파를 차단하여 강한 전자기파가 방출되는 전자기파로부터 사람을 보호할 수 있고, 또한 전자기파로 인한 전자기장치 상호간의 간섭을 방지할 수 있게 한 것이다.The present invention relates to a case for shielding electromagnetic waves generated from a mobile phone, and in particular, a transparent shielding layer woven in a mesh form of copper sulfate (CuSO 4 ), gold (Au), or silver (Ag) having excellent electromagnetic shielding capability and transparency. By laminating sheets to provide a case of a mobile phone to block electromagnetic waves generated from various mobile phones to protect people from the electromagnetic waves emitted strong electromagnetic waves, and also to prevent the interference between electromagnetic devices due to electromagnetic waves.

최근 휴대용 전화기 등 무선 통신 기기의 보급이 급속히 증가됨에 따라 생활의 편리성 도모에 기여하고 있으나, 생활의 편리성 이면에는 인체에 악 영향을 미치는 전자파라는 존재가 편리성에 가려져 등한시되어 왔던 것이 주지의 사실이다.In recent years, the spread of wireless communication devices such as mobile phones has contributed to the convenience of life, but it is well known that the existence of electromagnetic waves that adversely affect the human body has been neglected due to the convenience. to be.

최근 들어 건강에 대한 관심이 고조되면서 전자파와 건강에 대한 개연성에 대하여 논란이 지속되어 있으며, 전자파가 인체에 악 영향을 미친다는 사실들이 속속히 밝혀지고 있다.Recently, as interest in health has increased, controversy continues over the possibility of electromagnetic waves and health, and it is revealed that electromagnetic waves adversely affect the human body.

따라서 상기와 같은 전자파로 인한 피해를 최소화하기 위하여 여러 가지의 제안이 행하여지고 있으나 아직까지 실용화되고 있는 것은 거의 없으며 실용화되더라도 그 효과가 미약한 실정인 것이다.Therefore, various proposals have been made to minimize the damage caused by the electromagnetic waves, but there are few practical applications so far, and even if they are practical, their effects are weak.

한편 휴대폰에서 발생되는 전자파를 최소화하기 위한 방법으로는 핸드폰 하우징 내벽에 전자파 차폐물질을 피복 코팅하는 방법이 일반적으로 채용되며 이 방법은 하우징 내벽에 전자파 차폐물질을 코팅하므로 가장 효과적인 방법으로 생각할 수 있으나, 핸드폰에 설치된 키 패드와 수신부인 안테나는 전자파의 차단이 불가능하여 전자파가 키 패드와 수신부로 다량 방출되므로 사용자가 전자파에 완전 노출되는 문제점이 것이다.On the other hand, as a method for minimizing electromagnetic waves generated in a mobile phone, a method of coating and coating the electromagnetic shielding material on the inner wall of the cellular phone housing is generally adopted. This method may be considered the most effective method because the electromagnetic shielding material is coated on the inner wall of the housing. The keypad and the receiver, which are installed in the mobile phone, cannot block the electromagnetic waves, so that a large amount of electromagnetic waves are emitted to the keypad and the receiver, thereby completely exposing the user to electromagnetic waves.

이와 같은 문제점을 해소하기 위하여 최근에는 휴대폰에 설치된 안테나를 제거한 후 이에 전자파를 차단하는 안테나를 교체하도록 한 안테나가 있으나 이는 수신 불량이 발생하는 문제점이 있으며, 휴대폰 본체 즉, 키 패드에서 발생되는 전자파는 차단할 수 없다는 단점이 있는 것이다.In order to solve such a problem, there is an antenna to replace the antenna that blocks the electromagnetic wave after removing the antenna installed in the mobile phone recently, but this has a problem of poor reception, the electromagnetic wave generated from the mobile phone main body, that is, the keypad The disadvantage is that it can not be blocked.

또한 전자파 차단 물질을 면사와 함께 직조한 직물 또는 도전성 카본, 구리 입자, 망간 등의 도전성 물질을 코팅한 직물지로 핸드폰을 수납할 수 있도록 한 케이스가 제공되고 있으며, 이는 핸드폰을 내부에 수납하여 보관 및 휴대하므로 휴대시에는 전자파를 효과적으로 차단할 수 있으나 휴대폰을 사용하고자 하는 경우 반드시 케이스에서 빼낸 후 사용하여야 함으로 휴대폰의 사용중에는 전자파를 차단할 수 없다는 단점이 있는 것이다.In addition, a case is provided in which a cell phone can be stored in a fabric woven with an electromagnetic shielding material together with cotton yarn or a coated paper coated with a conductive material such as conductive carbon, copper particles, and manganese. As it is portable, it can effectively block electromagnetic waves, but if you want to use a mobile phone, you must remove it from the case and use the mobile phone.

본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 목적은 전자파 차폐능이 우수한 황산동(CuSO4)이나 금(Au) 또는 은(Ag)을 혼합하여 메쉬 형태로 직조한 차폐층을 투명성을 갖는 커버와 합지하여 커버의 투명성을 유지시켜 휴대폰 본체의 키 패드는 물론 송신부 등을 전체적으로 감쌀 수 있도록 하여 유해 전자파로부터 인체를 보호할 수 있도록 한 것이다.The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is a shield layer woven in a mesh form by mixing copper sulfate (CuSO 4 ), gold (Au) or silver (Ag) excellent in electromagnetic shielding ability It is to be able to protect the human body from harmful electromagnetic waves by laminating the cover with the transparency to maintain the transparency of the cover to cover the keypad of the mobile phone body as well as the transmission unit as a whole.
