Abstract

PURPOSE: An electromagnetic wave shielding cable is provided to protect human body or animals and plants from electromagnetic wave by preventing the electromagnetic wave generated from the cable from being radiated to outside. CONSTITUTION: An electromagnetic wave shielding cable comprises a cable(1) made of an electrical conductive material and a covering(2) formed along the outer surface of the cable. The covering includes a first silicon layer(21), an electromagnetic wave shielding layer(22) and a second silicon layer(23) formed in sequence. The electromagnetic wave shielding layer is made of an aluminum. When a current flows along the cable, an electromagnetic wave is generated from the cable. Thus-generated electromagnetic wave permeates through the first silicon layer and is absorbed in the electromagnetic wave shielding layer. The second silicon layer serves as a protective layer for the electromagnetic wave shielding layer.

본 발명의 전자파 차단 전선에 관한 것으로서, 전류가 흐르는 전선에서 발생하는 전자파가 외부로 방사되는 것을 차단하도록 한 전자파 차단 전선에 관한 것이다.The present invention relates to an electromagnetic wave shielding wire, and more particularly, to an electromagnetic wave shielding wire which blocks electromagnetic radiation generated from an electric current flowing wire to the outside.

최근 전자파의 유해성에 대한 논란은 계속되어지고 있으며 이러한 전자파의 차폐 수단의 개발 또한 발전하고 있다.Recently, the debate about the harmfulness of electromagnetic waves continues and the development of the shielding means of such electromagnetic waves is also developing.

이러한 전자파 차폐수단은 일반적으로 휴대폰이나 컴퓨터 기기, 그리고 가전제품에 응용되는 것과 수맥을 차단하기 위한 의복이나 도료 등에 전자파 차단 물질을 첨가하는 방법이 대부분을 이루고 있다.The electromagnetic wave shielding means is generally applied to mobile phones, computer devices, and home appliances, and a method of adding an electromagnetic wave shielding material to clothing or paint for blocking water veins.

하지만 어디서나 흔히 볼 수 있는 전선에서 발생하는 전자파를 차단하는 기술의 발전은 상대적으로 미약하여 일반 가정에서 또는 고압전선과 인접한 곳에서 인체는 무방비로 전자파에 노출되고 있는 실정이다.However, the development of technology that blocks electromagnetic waves generated from wires that are commonly seen everywhere is relatively weak, and the human body is exposed to electromagnetic waves without defense in general homes or near high voltage cables.

특히 고압의 전류가 흐르는 곳에서는 암의 발생률의 수배나 증가하고 가축들의 난산이 증가하며 농작물의 수확량이 줄어드는 등의 피해가 발생하고 있어 현재 새로운 송전탑의 건설을 각 지역에서 반대를 하고 있는 주요 이유가 되고 있다.In particular, where high-voltage current flows, the occurrence rate of cancer increases, the difficulty of raising livestock, and the yield of crops decreases. The main reason for opposing the construction of new transmission towers is the current reason. It is becoming.

또한 발생한 전자파는 전도성이 있는 물질에 흡수되어 상기 작게는 정전기 발생에서 인체가 직접 접촉할 경우 인체에 영향을 주기도 한다.In addition, the generated electromagnetic waves are absorbed by a conductive material, which may affect the human body when the human body directly contacts in the generation of static electricity.

따라서 전자파를 차단할 수 있는 전선의 개발은 시급하다고 하겠다.Therefore, it is urgent to develop a wire that can block electromagnetic waves.

본 발명은 상기와 같은 문제점을 해결하고자 발명된 것으로서, 그 목적은 전선에서 발생하는 전자파가 외부로 방출되는 것을 막는데 있다.The present invention has been invented to solve the above problems, the object is to prevent the electromagnetic waves generated from the wires to be emitted to the outside.

상기와 같은 목적을 달성하기 위하여 본 발명은 전기 전도성을 가진 물질로 이루어진 전선과 피복으로 이루어지는 전선에 있어서, 상기 전선의 외면에 규소층과 전자파 차단층과 실리콘층이 순차적으로 형성된 피복이 형성됨을 특징으로 하는전자파 차단 전선에 관한 것이다.In order to achieve the above object, the present invention is a wire consisting of a wire and a coating made of an electrically conductive material, characterized in that the coating is formed on the outer surface of the wire formed of a silicon layer, an electromagnetic wave shielding layer and a silicon layer sequentially It relates to an electromagnetic wave shielding wire.

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세히 설명하면 다음과 같다.Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

도 1은 본 발명의 일실시 예를 나타낸 사시도 이며 도 2는 본 발명의 일실시 예에 따른 단면도 로서, 전기 전도성을 가진 물질로 이루어진 전선(1)과 피복(2)으로 이루어지는 전선에 있어서, 상기 전선(1)의 외측면에 규소층(21)과 전자파 차단층(22)과 실리콘층(23)이 순차적으로 형성된 피복(2)이 형성됨을 특징으로 하는 전자파 차단 전선을 나타내었다.1 is a perspective view showing an embodiment of the present invention, Figure 2 is a cross-sectional view according to an embodiment of the present invention, in the wire consisting of a wire (1) and the cover (2) made of an electrically conductive material, the The electromagnetic wave shielding wire is characterized in that a sheath 2 on which the silicon layer 21, the electromagnetic wave shielding layer 22, and the silicon layer 23 are sequentially formed is formed on the outer surface of the electric wire 1.

일반적으로 전선(1)은 전도성이 좋은 금속으로 이루어져 있으나 가격에 따른 생산비의 부담으로 구리나 알루미늄합금으로 많이 쓰이고 있다.In general, the wire (1) is made of a good conductive metal, but is widely used as a copper or aluminum alloy due to the cost of production according to the price.

따라서 전자파 차폐 효율이 뛰어난 금이나 은과 같은 금속으로 전자파 차단층(22)을 형성하면 그 효율은 뛰어날 것이나 고가의 재료이기에 일반적으로 사용하는 알루미늄으로 대체를 하여 사용하도록 하는 것이 바람직한 실시 예일 것이다.Therefore, if the electromagnetic wave shielding layer 22 is formed of a metal such as gold or silver having excellent electromagnetic shielding efficiency, the efficiency will be excellent, but since it is an expensive material, it will be preferable to replace it with aluminum which is generally used.

이때 발생된 전자파(3)는 규소층(21)을 투과하여 전자파 차단층(22)에 흡수되게 되며 상기 전자파 차단층(22)과 외부를 차단시키기 위하여 실리콘층(23)을 형성하였다.At this time, the generated electromagnetic wave 3 is transmitted through the silicon layer 21 to be absorbed by the electromagnetic wave blocking layer 22, and the silicon layer 23 is formed to block the electromagnetic wave blocking layer 22 and the outside.

또한 상기 규소층(21)은 전선(1)과 전자파 차단층(22)이 직접 접촉하는 것을방지하고 전자파(3)는 투과할 수 있도록 형성하였다.In addition, the silicon layer 21 is formed to prevent direct contact between the wire 1 and the electromagnetic wave shielding layer 22 and to transmit the electromagnetic wave 3.

또 본 발명은 통상의 전선(1)의 피복(2)을 전자파 차단 수단과 상기 전자파 차단 수단과 전선과의 접촉을 막는 층과 상기 전자파 차단 수단과 외부와의 접촉을 막는 층으로 이루어 진 것으로서 통상의 지식을 가진 자라면 여러 가지 균등한 실시 예를 안출해 낼 수 있을 것이다.In addition, the present invention is made of a conventional coating (2) of the wire (1) consisting of a layer for blocking the contact between the electromagnetic wave blocking means, the electromagnetic wave blocking means and the wire, and the layer for preventing contact between the electromagnetic wave blocking means and the outside. Those skilled in the art will be able to come up with various equivalent embodiments.

상술한 바와 같이 본 발명은 전선에서 발생하는 유해한 전자파가 외부로 방사되는 것을 막을 수 있도록 함으로서, 전자파에 의하여 인체나 기타 동식물에 미치는 악영향을 줄일 수 있는 효과가 있다.As described above, the present invention can prevent harmful electromagnetic waves generated from electric wires from being radiated to the outside, thereby reducing the adverse effects on the human body or other animals and plants by electromagnetic waves.
