Description

자동차용 점화 니크롬선 케이블{The nichrome cable for car}Ignition nichrome wire cable for car {The nichrome cable for car}

본 발명은 자동차용 점화 니크롬선 케이블에 관한 것으로서, 좀더 상세하게 설명하면 자동차의 점화플러그에 고압의 전력을 공급하는 니크롬선 케이블이의 일 끝단을 커팅할 때 외부도체가 손상되어 휘거나 구부리는 과정에서 상기 외부도체가 단선되는 문제점을 해결하기 위하여 개발된 자동차용 점화 니크롬선 케이블에 관한 것이다.The present invention relates to an ignition nichrome wire cable for an automobile, and in more detail, a process of bending or bending an outer conductor when the end of a nichrome wire cable for supplying high voltage power to an automobile spark plug is damaged. The present invention relates to an automotive ignition nichrome wire cable developed to solve the problem that the external conductor is disconnected.

일반적으로, 자동차용 점화 니크롬선 케이블은 점화코일에서 발생되는 대략 20,000V의 고전압 신호를 배전기와 점화플러그에 전달하는 케이블로 과거에는 일반 고전압의 전선과 같이 구리 등과 같은 전도성이 우수한 금속을 이용하여 제작하였다.In general, automotive ignition nichrome wire cable is a cable that transmits a high voltage signal of about 20,000V generated from an ignition coil to a distributor and a spark plug. In the past, the ignition nichrome wire cable is made of a metal having high conductivity such as copper, such as a general high voltage wire. It was.

하지만 현대에는 자동차에 수많은 전자장비가 장착되고 특히 안전적인 운행에 필수적인 브레이크 시스템과 같은 차량의 전자제어장치(ECU) 등에 금속선에 전류가 흐름으로 발생되는 고주파 노이즈는 오작동 또는 고장을 가져올 우려가 많아 최근에는 고주파 노이즈를 최소화할 수 있는 고분자 전도성 물질을 이용하여 이그니션 케이블을 제조하고 있다.However, in modern times, a lot of electronic equipment is installed in automobiles, especially high-frequency noise generated by current flow through metal wires in electronic control unit (ECU) such as brake system which is essential for safe driving. Ignition cable is manufactured using a polymer conductive material that can minimize high frequency noise.

도 3은 종래 니크롬선 케이블을 도시한 사시도로서, 니크롬선 케이블은 크게 고주파 노이즈가 적은 도전체로 이루어진 심선(1)과, 이 심선(1)에 피복되는 절연체(2)와, 절연체(2) 외부에 피복되는 외피(4)로 구성된다.3 is a perspective view showing a conventional nichrome wire cable, wherein the nichrome wire cable is made of a conductor wire 1 made of a conductor having a large amount of high frequency noise, an insulator 2 coated on the core wire 1, and an outside of the insulator 2. It consists of an outer sheath 4 covered with.

여기서, 심선(1)은 내부도체(11)와 상기 내부도체(11)의 외주면에 도전성 카본이 포함되는 수지재를 압출성형한 외부도체(12)로 구성된다.Here, the core wire 1 is composed of an inner conductor 11 and an outer conductor 12 extruded from a resin material containing conductive carbon on the outer circumferential surface of the inner conductor 11.

특히 상기 내부도체(11)의 재료는 탄소섬유, 유리섬유(glass fiber), 아라미드섬유(aramid fiber), 캐브라 섬유 등이 주로 사용된다.In particular, the material of the inner conductor 11 is mainly used, such as carbon fiber, glass fiber (glass fiber), aramid fiber (aramid fiber), cambra fiber.

또한 경우에 따라 고주파 노이즈를 확실하게 제거하기 위해, 외부도체(12) 표면에 흑연을 코팅하여 도전성 피막층(14)을 형성할 수 있으며, 절연체(2)와 외피(4) 사이에는 도시된 바와 같이 보강재(3)가 삽입되는 경우도 있다.In addition, in some cases, in order to reliably remove the high frequency noise, a conductive coating layer 14 may be formed by coating graphite on the surface of the outer conductor 12, and as shown between the insulator 2 and the shell 4. The reinforcement 3 may be inserted in some cases.

그러나, 이러한 종래 니크롬선 케이블은 배전기나 점화플러그에 접속하기 위해 케이블 단부를 커팅할 때, 케이블의 직경이 정밀하지 않거나 작업자의 부주의에 의해 종종 외부도체(12)의 표면에 손상이 발생된다.However, such a conventional nichrome wire cable, when cutting the cable end to connect to the distributor or spark plug, the diameter of the cable is not precise or carelessness of the operator often causes damage to the surface of the outer conductor 12.

이렇게 외부도체(12)가 손상되면, 케이블을 접속하기 위해 휘거나 구부리는 과정에서, 외부도체(12)의 손상 부위가 깊어지거나 외부도체(12)가 단선되는 현상이 발생된다.When the outer conductor 12 is damaged in this way, in the process of bending or bending to connect the cable, a damage portion of the outer conductor 12 is deepened or the outer conductor 12 is disconnected.

이러한 외부도체의 손상은 고압의 전류가 인가되지 못하게 되어 하나 이상의 점화플러그가 작동 불능의 상태로 엔진출력이 저하되거나 시동이 걸리지 않게 되는 문제점이 발생한다.The damage of the external conductor is a problem that the high-power current is not applied to one or more spark plugs are inoperable, the engine output is reduced or does not start.

또한 점화플러그가 작동하지 않더라도 엔진이 가동되면서 연료는 변함없이 공급되어 연소되지 않은 상태로 배기되며 이러한 휘발성 배기가스로 인하여 환경오염의 문제뿐만 아니라 자동차의 화재 위험성까지 발생하는 것이다.In addition, even if the spark plug does not work, the fuel is invariably supplied as the engine is operated and exhausted without combustion. The volatile exhaust gas causes not only environmental pollution but also a fire hazard of a vehicle.

본 발명은 상기와 같은 문제점을 해결하기 위하여 개발된 것으로서, 그 목적은 니크롬선 케이블이 단선되더라도 전력을 공급할 수 있는 니크롬선 케이블을 개발하는 것이다.The present invention was developed to solve the above problems, the object of which is to develop a nichrome wire cable that can supply power even if the nichrome wire cable is disconnected.

상기와 같은 목적을 달성하기 위하여 본 발명은 점화플러그에 전력을 공급하기 위한 자동차용 점화 니크롬선 케이블에 있어서;In order to achieve the above object, the present invention provides an automotive ignition nichrome wire cable for supplying power to a spark plug;

중앙에 형성되는 내부도체와, 상기 내부도체의 외주면에 도전성 카본을 포함한 수지에 의하여 피복됨으로 이루어지는 외부도체와, 상기 외부도체의 외주면을 따라 스프링의 형상으로 권취되는 니크롬선으로 이루어지는 심선과;A core wire formed of an inner conductor formed in the center, an outer conductor formed of a resin including conductive carbon on the outer circumferential surface of the inner conductor, and a nichrome wire wound in a spring shape along the outer circumferential surface of the outer conductor;

상기 심선의 외주면에 피복되는 내열성 및 절연성을 가진 절연체와;An insulator having heat resistance and insulation coated on an outer circumferential surface of the core wire;

상기 절연체의 외주면을 감싸면서 형성되는 부직포로 이루어지는 보강재와;A reinforcing member made of a nonwoven fabric formed while covering an outer circumferential surface of the insulator;

상기 보강재의 외주면에 피복되는 외피로 구성됨을 특징으로 한다.Characterized in that it consists of an outer shell coated on the outer peripheral surface of the reinforcing material.

상술한 바와 같이 본 발명은 니크롬선 케이블이 중간에 단선 되더라도 전력은 계속 공급될 수 있도록 하여 급작스럽게 시동이 걸리지않거나 엔진의 기동이 멈추는 등의 위급 상황을 줄이는 효과가 있디.As described above, the present invention has the effect of reducing the emergency situation such as not starting suddenly or stopping the start of the engine by continuing to supply power even if the nichrome wire cable is disconnected in the middle.

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세하게 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 일 실시 예에 따른 사시도이며, 도 2는 본 발명의 일 실시 예에 따른 단면도로서, 점화플러그에 전력을 공급하기 위한 자동차용 점화 니크롬선 케이블에 있어서;1 is a perspective view according to an embodiment of the present invention, Figure 2 is a cross-sectional view according to an embodiment of the present invention, in the automotive ignition nichrome wire cable for supplying power to the spark plug;

중앙에 형성되는 내부도체(11)와, 상기 내부도체(11)의 외주면에 도전성 카본을 포함한 수지에 의하여 피복됨으로 이루어지는 외부도체(12)와, 상기 외부도체(12)의 외주면을 따라 스프링의 형상으로 권취되는 니크롬선(13)으로 이루어지는 심선(1)과;The inner conductor 11 formed in the center, the outer conductor 12 which consists of a resin containing conductive carbon on the outer peripheral surface of the inner conductor 11, and the shape of a spring along the outer peripheral surface of the outer conductor 12 A core wire 1 composed of a nichrome wire 13 wound up with a wire;

상기 심선(1)의 외주면에 피복되는 내열성 및 절연성을 가진 절연체(2)와;An insulator (2) having heat resistance and insulation coated on an outer circumferential surface of the core wire (1);

상기 절연체(2)의 외주면을 감싸면서 형성되는 부직포로 이루어지는 보강재(3)와;A reinforcing member (3) made of a nonwoven fabric formed while covering the outer circumferential surface of the insulator (2);

상기 보강재(3)의 외주면에 피복되는 외피(4)로 구성됨을 특징으로 하는 자동차 니크롬선 케이블을 나타내었다.An automobile nichrome wire cable is shown, which is composed of an outer sheath 4 coated on an outer circumferential surface of the reinforcement 3.

이때 본 원인은 상기 내부도체(11)는 열에 강하고 도전성이 우수한 케브라 섬유를 사용하였다.At this time, the cause is that the inner conductor 11 used a Kevlar fiber strong in heat and excellent in conductivity.

상기 도면에서와 같이 상기 외부도체(12)의 재질은 도전성 카본이 함유된 수지로 이루어지기에 최초 케이블을 절단하여 연결하는 과정에서 다소 간의 흠이 발생하면 상기 케이블을 구부리는 과정에서 그 흠은 점점 커지게 되어 단선되는 경우가 발생하는 것이다.As shown in the figure, the material of the outer conductor 12 is made of a resin containing conductive carbon, so if a slight flaw occurs in the process of cutting and connecting the first cable, the flaw is gradually obtained in the bending of the cable. If it becomes large, it may cause a disconnection.

하지만 본 발명에서는 상기 외부도체(12)의 외주면을 따라 감긴 니크롬 선(13)이 이러한 외부도체의 단선에도 전류가 계속 흐를 수 있게 하는 것이다.However, in the present invention, the nichrome wire 13 wound along the outer circumferential surface of the outer conductor 12 allows the current to continue to flow even in the disconnection of the outer conductor.

이는 종래 도전성 피막층과 동일한 역할을 하면서도 케이블 손상시에 전류를 흐르게 하여 갑작스럽게 시동이 걸리지 않거나, 엔진 출력의 저하, 또는 갑작스런 엔진의 정지 등이 가져올 수 있는 불편함뿐만 아니라 사고의 위험을 줄이는 역할을 하는 것이다.This plays the same role as the conventional conductive coating layer, but it also plays a role in reducing the risk of an accident as well as the inconvenience that can be caused by suddenly starting the engine due to electric current in case of cable damage, deterioration of engine output, or sudden engine stop. It is.

몰론 외부도체(12)가 중간에 끊어진 상태에서 상기 니크롬선(13)이 외부도체와 같은 충분한 전력의 공급이 이루어지는 것이 아니므로 운전자는 차량의 이상을 어느정도 인지할 수 있을 것이다.Of course, since the nichrome wire 13 is not supplied with sufficient power as the external conductor while the external conductor 12 is cut in the middle, the driver may recognize the abnormality of the vehicle to some extent.

즉 외부도체가 끊어진 상태에서도 동일하게 전력을 공급하도록 하는 불안정된 상황을 만드는 것이 아니라 최소한의 전력을 공급하도록 하여 수리할 수 있는 곳까지 차량의 기동 상태를 유지할 수 있도록 함이 본 발명의 목적이라 할 것이다.That is, it is an object of the present invention to maintain the starting state of the vehicle to the point where it can be repaired by supplying the minimum power, rather than creating an unstable situation in which the same power is supplied even when the external conductor is broken. will be.
