아크 방지가 가능한 탄소발열선과 전선의 연결구조{Connection structure of a carbon heating wire and an electric code}Connection structure of a carbon heating wire and an electric code

본 고안은 '아크 방지가 가능한 탄소발열선과 전선의 연결구조'에 관한 것으로서, 더욱 상세히는 슬리브 내부에 용융체가 수용되어 탄소발열선과 슬리브 사이에 아크가 발생하지 않도록 한, '아크 방지가 가능한 탄소발열선과 전선의 연결구조'에 관한 것이다.The present invention relates to a connection structure of carbon heating wire and wire capable of preventing arc, and more particularly, to prevent arcing between the carbon heating wire and the sleeve, in which a molten body is accommodated inside the sleeve to prevent arcing. Connection structure between wires and wires.

이하, 첨부되는 도면과 관련하여 종래 기술을 살펴보면 다음과 같다.Hereinafter, the prior art will be described with reference to the accompanying drawings.

도 1은 종래 기술에 의한 탄소발열선과 전선의 연결구조를 도시한 분해 단면도, 도 2는 종래 기술에 의한 탄소발열선과 전선의 연결구조를 도시한 단면도로서 함께 설명한다.1 is an exploded cross-sectional view showing a connection structure of the carbon heating wire and the wire according to the prior art, Figure 2 is shown as a cross-sectional view showing a connection structure of the carbon heating wire and the wire according to the prior art.

일반적인 탄소발열선(10)과 전선(20)의 연결구조를 살펴보면, 관 형상의 슬리브(30, sleeve)가 구성되고, 상기 슬리브(30)의 일측에 탄소발열선(10)의 종단부가 끼워지고, 상대측에는 전선(20)의 피복된 구리선(23)이 삽입된다. 그리고 상기 슬리브(30)는 압축되어 상기 탄소발열선(10)과 구리선(23)이 밀착되어 구성된다. 상기 탄소발열선(10)과 전선(20)의 연결 부분의 누전을 방지하기 위해 탄소발열 선(10)과 슬리브(30), 전선(20)에 걸쳐서 절연테이프(미도시)를 감아서 구성할 수도 있다.Looking at the connection structure of the general carbon heating wire 10 and the electric wire 20, a tubular sleeve 30, the sleeve is configured, the end of the carbon heating wire 10 is fitted to one side of the sleeve 30, the other side The coated copper wire 23 of the electric wire 20 is inserted into it. And the sleeve 30 is compressed is composed of the carbon heating wire 10 and the copper wire 23 is in close contact. In order to prevent the leakage of the connection portion of the carbon heating wire 10 and the wire 20 may be configured by winding an insulating tape (not shown) over the carbon heating wire 10, the sleeve 30, the wire 20 have.

상기 슬리브(30)는 전기의 도체로 형성되는데, 구리나 니켈 중 어느 하나로 형성되든지, 구리와 니켈의 합금으로 만들어질 수 있다. 그외 다양한 도체로 형성될 수 있다. The sleeve 30 is formed of an electrical conductor, which may be made of copper or nickel, or an alloy of copper and nickel. Other conductors may be formed.

따라서, 전류가 상기 구리선, 슬리브(30), 탄소발열선(10)을 통해 흐르게 됨으로써 상기 탄소발열선(10)에서 저항열이 발생하게 된다.Therefore, the current flows through the copper wire, the sleeve 30, and the carbon heating wire 10 so that the heat of resistance is generated in the carbon heating wire 10.

상기 탄소발열선의 경우, 나노 굵기의 선경(線徑)을 가지는 미세한 탄소섬유가 모여서 형성된 것으로서, 슬리브(sleeve)의 일측에 탄소발열선의 종단부를 끼우고 상대측에 전선을 삽입한 후, 압박한다고 하더라도, 슬리브가 여러 가닥으로 형성된 탄소섬유와 일일이 밀착될 수는 없다. 즉, 상기 슬리브에 밀착되지 않는 탄소섬유가 다수 존재하게 된다. 물론, 전선의 경우, 하나의 구리선으로 형성됨으로써 슬리브와의 밀착이 가능하다. 따라서, 전류가 흐르게 되면, 상기 밀착되지 않은 탄소섬유와 슬리브 사이에서는 1000℃ 이상의 아크(arc)가 여러 번 발생하여 슬리브는 가열되면서 연화되고, 온도가 계속 상승하게 되면 용융되는 부분이 생겨서 이 부분에서 홀(hole)이 발생하게 된다. 물론, 이때 상기 절연 테이프도 녹아서 상기 홀은 외부와 연통된다. 따라서, 상기 슬리브에서 절연 테이프가 녹아서 노출된 부분을 통해 아크가 외부로 튀어나가게 됨으로써, 주위에 인화성 물질이 있을 경우, 큰 화재를 일으키게 된다.In the case of the carbon heating wire, fine carbon fibers having a nano-wire diameter are formed, and even after pressing the end of the carbon heating wire on one side of the sleeve and inserting the wire on the opposite side, the wire is pressed. The sleeve cannot be in close contact with the carbon fiber formed of several strands. That is, a large number of carbon fibers are not in close contact with the sleeve. Of course, in the case of the electric wire, it is possible to be in close contact with the sleeve by being formed of one copper wire. Therefore, when an electric current flows, an arc of 1000 ° C. or more occurs several times between the carbon fiber and the sleeve that is not tight, and the sleeve softens as it is heated. Holes are generated. Of course, at this time, the insulating tape is also melted so that the hole communicates with the outside. Therefore, the arc sticks out through the exposed portion of the insulating tape that melts in the sleeve, causing a large fire when flammable material is present in the surroundings.

본 고안은 관 형상의 도체인 슬리브가 구성되고, 상기 슬리브의 일측에 다수의 탄소섬유가 다발로 형성된 탄소발열선의 종단부가 끼워지고, 상기 슬리브의 상대측에 전선의 피복된 구리선이 삽입되고, 상기 슬리브는 압축되어 구성되는 탄소발열선과 전선의 연결구조에 있어서; 상기 슬리브 내부에서 탄소발열선과 구리선 사이에 도체인 용융체가 개재되어 구성되고, 상기 용융체는 상기 슬리브 보다 용융 점이 낮고, 상기 탄소발열선의 저항열 보다 높도록 구성한다.The present invention is composed of a sleeve that is a tubular conductor, the end of the carbon heating wire formed of a plurality of carbon fibers bundle on one side of the sleeve is fitted, the copper wire coated with the wire is inserted into the other side of the sleeve, the sleeve In the connection structure of the carbon heating wire and the wire is compressed; The melt is a conductor is interposed between the carbon heating wire and the copper wire inside the sleeve, the melt is configured to have a lower melting point than the sleeve, higher than the heat of resistance of the carbon heating wire.

본 고안은 슬리브와 탄소섬유 사이에 아크가 발생하게 되면 용융체가 녹으면서 탄소섬유와 슬리브 사이의 극간을 메우게 되어 아크의 발생을 중단시킨다. 따라서, 슬리브가 용융되어 홀이 발생하는 현상을 방지하게 되어 상기 홀을 통해 아크가 튀어나가게 됨으로써 발생하는 화재의 발생을 예방할 수 있는 효과가 있다.When the arc is generated between the sleeve and the carbon fiber, the invention melts the melt and fills the gap between the carbon fiber and the sleeve to stop the generation of the arc. Therefore, the sleeve is melted to prevent a phenomenon in which the hole is generated, thereby preventing the occurrence of a fire caused by the arc popping out through the hole.

이하, 첨부되는 도면과 관련하여 상기 과제를 해결하기 위한 본 고안의 구성을 살펴보면 다음과 같다.Hereinafter, with reference to the accompanying drawings look at the configuration of the present invention for solving the above problems.

일반적인 '탄소발열선과 전선의 연결구조(100)'를 살펴보면, 관 형상의 슬리브(130, sleeve)가 구성되고, 상기 슬리브(130)의 일측에 다수의 탄소섬유(113)가 다발로 형성된 탄소발열선(110)의 종단부가 끼워지고, 상대측에는 전선(120)의 피복된 구리선(123)이 삽입된다. 그리고 상기 슬리브(130)는 압축되어 상기 탄소발열선(110)과 구리선(123)이 밀착되어 구성된다. Looking at the general 'carbon heating wire and wire connection structure 100', a tubular sleeve (130, the sleeve) is configured, the carbon heating wire formed of a plurality of carbon fibers 113 on one side of the sleeve 130 The end of the 110 is inserted, and the copper wire 123 of the wire 120 is inserted into the other side. In addition, the sleeve 130 is compressed so that the carbon heating wire 110 and the copper wire 123 are in close contact with each other.

상기 슬리브(130)는 전기의 도체로 형성되는데, 구리나 니켈 중 어느 하나로 형성되든지, 구리와 니켈의 합금으로 만들어질 수 있다. 그외 다양한 도체로 형성될 수 있다. The sleeve 130 is formed of an electrical conductor, which may be made of copper or nickel, or an alloy of copper and nickel. Other conductors may be formed.

상기 '탄소발열선과 전선의 연결구조(100)'는 필요에 따라 노출되도록 구성될 수도 있고, 탄소발열선(110)과 전선(120)의 연결 부분의 누전을 방지하기 위해 탄소발열선(110)과 슬리브(130), 전선(120)에 걸쳐서 절연 테이프(미도시)를 감아서 구성할 수도 있다.The carbon heating wire and the connection structure 100 of the wire 100 may be configured to be exposed as necessary, the carbon heating wire 110 and the sleeve to prevent the leakage of the connection portion of the carbon heating wire 110 and the wire 120. The insulating tape (not shown) can be wound and constructed over the 130 and the electric wire 120.

본 고안에서는 상기 탄소발열선(110)과 슬리브(130) 사이에 아크가 발생하는 현상을 방지하도록 함으로써, 슬리브(130)에 홀(미도시)이 생기는 현상을 방지하여 아크로 인한 화재를 미연에 방지할 수 있도록 구성한 것을 특징으로 한다.In the present invention by preventing the occurrence of the arc between the carbon heating wire 110 and the sleeve 130, to prevent the phenomenon of the hole (not shown) in the sleeve 130 to prevent the fire due to the arc in advance. Characterized in that configured to be.

이를 위하여 본 고안에서는 다음과 같이 구성한다.To this end, the present invention is configured as follows.

상기 슬리브(130) 내부에 탄소발열선(110)과 구리선(123) 사이에, 아크열 때문에 용융되면서 도체인 용융체(140)가 개재되어 구성된다.Between the carbon heating wire 110 and the copper wire 123 in the sleeve 130, the melt 140, which is a conductor while melting due to arc heat, is interposed.

상기 용융체(140)는 실시예로써 상기 슬리브(130) 보다 용융점이 낮고 탄소발열선(110)의 발열온도 보다는 용융점이 높은 금속이 바람직하다. 일례로서, 용융점이 413℃인 납이나 72℃인 우드메탈이 가능하다.For example, the melt 140 may have a lower melting point than the sleeve 130 and a higher melting point than the heat generating temperature of the carbon heating wire 110. As an example, lead having a melting point of 413 ° C. or wood metal having a temperature of 72 ° C. is possible.

또한 상기 용융체(140)는 도 3에서처럼 알맹이 형상으로서 슬리브(130) 내부에 수용될 수도 있는데, 슬리브(130) 내측면에 부착된 상태로 형성될 수도 있다. 또는 상기 슬리브(130) 내부를 폐색하는 격막 형상으로 형성될 수도 있다. In addition, the melt 140 may be accommodated inside the sleeve 130 as a kernel shape, as shown in Figure 3, it may be formed in a state attached to the inner surface of the sleeve 130. Alternatively, the sleeve 130 may be formed in a diaphragm shape to close the inside of the sleeve 130.

상기 본 고안에 의하면, 구리선(123)을 통해서 전류가 흐르게 되면, 슬리브(130)와 탄소발열선(110)을 통해 전류가 도통되면서, 상기 탄소발열선(110)에서는 저항열이 발생하게 된다. 이때, 상기 슬리브(130)가 압축되어 있다 하더라도 탄소발열선(110)을 구성하는 미세한 나노섬유인 각각의 탄소섬유(113)와 밀접하게 접 촉할 수는 없다. According to the present invention, when the current flows through the copper wire 123, while the current is conducted through the sleeve 130 and the carbon heating wire 110, the heat of resistance is generated in the carbon heating wire 110. At this time, even if the sleeve 130 is compressed, it may not be in close contact with each carbon fiber 113, which is a fine nanofiber constituting the carbon heating wire 110.

따라서 접촉하지 못한 탄소섬유(113)와 슬리브(130) 사이에는 미세한 극간(미도시)이 형성되고 이 극간(미도시) 사이에는 1000℃ 이상의 아크(arc)가 다수회 반복하여 발생하게 된다. 그러면, 상기 용융체(140)가 용융되면서 탄소섬유(113) 사이사이와 탄소섬유(113)와 슬리브(130) 사이로 스며들면서 상기 극간(미도시)을 충전하게 되어 아크의 발생이 중단된다. 상기 용융체(140)는 도체이므로 전기의 도통에 전혀 문제가 되지 않는다. 따라서 상기 아크로 인해서 슬리브(130)에 홀(미도시)이 형성되는 문제점을 해결할 수 있다. Therefore, a minute gap (not shown) is formed between the carbon fiber 113 and the sleeve 130 that are not in contact, and an arc of 1000 ° C. or more is repeatedly generated many times between the gaps (not shown). Then, as the melt 140 melts, the gap between the carbon fibers 113 and the carbon fibers 113 and the sleeve 130 are filled, filling the gap (not shown), thereby generating the arc. Since the melt 140 is a conductor, there is no problem in electrical conduction at all. Therefore, the problem that the hole (not shown) is formed in the sleeve 130 due to the arc can be solved.

상기 용융체(140)의 융점은 탄소발열선(110)의 저항열 보다는 높고 상기 슬리브(130)의 용융점 보다는 높은 재질로 형성함으로써, 아크열로 용융되어 상기 극간(미도시)을 충전하고 나서, 탄소발열선(110)의 저항열 때문에 녹아서 흘러내림으로써 다시 극간(미도시)이 형성되는 현상이 방지되도록 한다.The melting point of the melt 140 is formed of a material higher than the heat of resistance of the carbon heating wire 110 and higher than the melting point of the sleeve 130, thereby melting with arc heat to fill the gap (not shown), and then heating the carbon heating wire. Due to the heat of resistance of 110 to melt and flow down to prevent the phenomenon that the gap (not shown) is formed again.
