Description

접지 구조를 구비한 통전 플라스틱 필러넥{An electric current plastic pillar neck equipped with grounding} An electric current plastic pillar neck equipped with grounding

본 발명은 통전 플라스틱 필러넥에 관한 것으로서, 차량의 주유시 주유건과 필러넥에 의해 발생되는 정전기를 보다 효율적으로 차체에 접지할 수 있도록 된 접지 구조를 구비한 통전 플라스틱 필러넥에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energized plastic filler neck, and more particularly, to an electrically energized plastic filler neck having a grounding structure that enables a more efficient grounding of static electricity generated by an oil supply key and a filler neck during vehicle lubrication.

일반 적으로 차량에 주유를 하기 위한 수단으로 주유관이 사용되고 있다. 이러한 주유관은 연료를 주유하기 위한 주유 건이 결합되는 필러넥과 필러넥에 결합되어 연료탱크에 연료를 유입시키는 유류관으로 형성된다.In general, an oil pipe is used as a means for lubricating a vehicle. The fuel pipe is formed of a filler neck coupled with a filler gun for lubricating fuel and an oil pipe for introducing fuel into the fuel tank.

상기와 같이 형성된 주유관을 통해 연료탱크에 연료를 주입하게 되면 주유건이 필러넥의 내부로 삽입되어 연료가 주입되게 된다.When fuel is injected into the fuel tank through the fuel pipe formed as described above, the fuel gun is inserted into the filler neck to inject fuel.

그런데, 주유 중 대기로 방출 되는 증발 가스는 상당량의 탄화수소를 포함하고 있다. 그리고 주유건은 어스되지 않은 상태에서 다량의 전하가 축적되게된다.However, the boil-off gas released to the atmosphere in the fuel oil contains a considerable amount of hydrocarbons. And the main fuel is a large amount of charge will accumulate in the unearthed state.

이러한 상태에서 주유건을 필러넥에 삽입하여 주유를 할경우에 접지되지 않은 주유건에 축적된 다량의 전하의 방전으로 인하여 화재가 발생할 수 있는 위험성이 있다. In such a state, when the gas is inserted into the filler neck and lubricated, there is a danger of fire due to the discharge of a large amount of charge accumulated in the ungrounded gas.

따라서, 정전기를 접지 시킬 수 있는 방법으로 금속재질의 필러넥을 사용하거나 플라스틱 재질의 필러넥에 금속 캡홀더와 접지선을 이용하여 차체에 접지하는 방법이 사용되고 있으며, 필러넥 자체를 통전 재질로 형성한 다음에 필러넥에 접지선의 한쪽은 필러넥에 결합시키고 다른 한쪽은 필러넥을 차체에 고정하기 위한 브라켓에 결합하여 정전기를 어스 시키는 방법을 사용하고 있다.Therefore, a method of grounding static electricity to a vehicle body using a metal filler neck or using a metal cap holder and a ground wire to a plastic filler neck is used. Next, one side of the ground wire is connected to the filler neck, and the other side is connected to the bracket for fixing the filler neck to the vehicle body to ground the static electricity.

그런데 상기와 같은 방법으로 정전기를 접지시키는 방법에는 다음과 같은 문제점이 있다.However, the method of grounding static electricity in the above manner has the following problems.

1. 금속재질의 필러넥과 접지선을 사용하여 정전기를 차체로 접지시키는 구조는 필러넥의 중량이 무겁고 부품수가 많아지는 문제점이 있다.1. The structure of grounding static electricity to the car body by using a metal filler neck and a ground wire has a problem that the weight of the filler neck is heavy and the number of parts increases.

2. 통전 재질의 필러넥과 사용하여 필러넥의 자체에 고정하기 위한 브라켓에 접지선을 연결하여 정전기를 접지하는 구조에 있어서는 브라켓을 금속 재질로 형성하여야 되는 문제점이 있으며, 필러넥에 결합된 접지선이 브라켓 까지 연장됨으로 인해 불필요하게 어스선의 길이가 길어지는 문제점이 있다.2. In the structure of grounding static electricity by connecting the ground wire to the bracket for fixing to the filler neck itself by using the filler neck made of a conductive material, there is a problem that the bracket must be formed of a metal material. There is a problem in that the length of the earth wire unnecessarily long due to the extension to the bracket.

3. 통전 재질의 필러넥을 사용한 경우에는 필러넥에 어스선을 단순히 클립을 사용하여 결합함으로 인해 차량에 충격이 가해진 경우에 어스선이 충격으로 인해 필러넥으로부터 이탈되는 문제점이 있다.3. In the case of using a filler neck made of a conductive material, there is a problem in that the ground wire is separated from the filler neck when the impact is applied to the vehicle by simply connecting the earth wire to the pillar neck using a clip.
