본 발명은 전자장비의 접지용 구조물에 관한 것으로서, 더욱 상세하게는, 마운팅 너트와 웰딩 볼트의 결합시, 마운팅 너트와 웰딩 볼트 사이에 전기적 통전성을 향상시킬 수 있도록 한 전자장비의 접지용 구조물(Earthing Structure for Electric Device of Car)에 관한 것이다.The present invention relates to a structure for grounding electronic equipment, and more particularly, a structure for grounding electronic equipment to improve electrical conduction between the mounting nut and the welding bolt when the mounting nut and the welding bolt are coupled. Structure for Electric Device of Car).

일반적으로, 차량의 각종 전자장비는, 배터리 및 발전기로부터 전원을 공급받아 작동되도록 구성되는데, 이때, 플러스(＋)단자는 전기 와이어에 의하여 직접 연결되나, 접지되는 마이너스(－)단자는 전자장비의 설치지점에 인접한 차체에 연결하여 접지시키도록 구성된다. 이와 같이, 전자장비의 마이너스(－)단자를 인접한 차체에 접속시키는 것은, 차체에 전체가 접지점의 역할을 하기 때문이다.In general, various electronic equipment of a vehicle is configured to be operated by receiving power from a battery and a generator. In this case, a positive (+) terminal is directly connected by an electric wire, but a negative (−) terminal to be grounded is It is configured to be connected to the vehicle body adjacent to the installation point and grounded. In this way, the negative terminal of the electronic equipment is connected to the adjacent vehicle body because the whole body serves as a grounding point.

도 1은 종래의 접지용 구조물의 분해 단면도를 도시한 것으로서, 차체(P)에 용접된 웰딩 볼트(11)에 접지용 터미널 단자(T)와 투스 와셔(tooth washer)(12)를 차례로 끼운 다음 그 위에 마운팅 너트(13)를 체결시키도록 구성된다. 이러한 구성에 의하여 전자장비로부터 상기 접지용 터미널 단자(T)로 인가되는 마이너스(－) 전하가 투스 와셔(12), 마운팅 너트(13) 및 웰딩 볼트(11)를 차례로 경유한 다음, 차체(P)에 인가된 후, 공기 중으로 방전되게 되는 것이다.1 illustrates an exploded cross-sectional view of a conventional grounding structure, in which a grounding terminal terminal T and a tooth washer 12 are sequentially inserted into a welding bolt 11 welded to a vehicle body P. It is configured to fasten the mounting nut 13 thereon. By this configuration, the negative (−) charge applied from the electronic equipment to the ground terminal terminal T passes through the tooth washer 12, the mounting nut 13, and the welding bolt 11 in sequence, and then the vehicle body P ) Is then discharged into the air.

그러나, 상기와 같은 종래의 접지용 구조물의 결합시, 웰딩 볼트(11)를 용접시킨 상태에서 페인트 등으로 차체를 도장한 다음, 접지용 터미널 단자(T) 및 마운팅 너트(13)를 결합시키게 되는데, 이때, 상기 웰딩 볼트(11)의 외면에도 페인트 등의 도장재가 도포된 상태이므로, 웰딩 볼트(11)와 마운팅 너트(13) 간의 전기적 접속이 불량하게 되는 경우가 빈번히 발생되며, 이에 따라 접지용 터미널 단자(T)에 접속된 전자장비의 접지가 충분히 이루어지지 않게 되어 전자장비의 오동작을 유발시키게 되는 문제점이 있다.However, when the conventional grounding structure is coupled as described above, the vehicle body is painted with paint or the like in the state in which the welding bolt 11 is welded, and then the grounding terminal terminal T and the mounting nut 13 are coupled. In this case, since a coating material such as paint is also applied to the outer surface of the welding bolt 11, the electrical connection between the welding bolt 11 and the mounting nut 13 is often poor, and thus, grounding is performed. There is a problem that the grounding of the electronic equipment connected to the terminal terminal (T) is not sufficiently made to cause a malfunction of the electronic equipment.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 마운팅 너트의 내면에 돌출된 링을 결합시킴으로써, 마운팅 너트와 웰딩 볼트의 결합시, 마운팅 너트와 웰딩 볼트 사이에 전기적 통전성을 향상시킬 수 있도록 한 전자장비의 접지용 구조물을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, by coupling the ring protruding to the inner surface of the mounting nut, when the mounting nut and the welding bolt is coupled, to improve the electrical conduction between the mounting nut and the welding bolt. The purpose is to provide a grounding structure for electronic equipment.

Then, when the vehicle body P is coated with paint or the like, a thick coating material is applied to the outer surfaces of the vehicle body P and the welding bolts 11. In this state, the grounding terminal terminal T and the tooth washer 12 are coupled to the welding bolt 11, and then the mounting nut 20 in which the protruding ring 30 is inserted into the insertion groove 20a is welded. To the bolt (11). At this time, as the mounting nut 20 is fastened to the welding bolt 11, the protruding ring 30, which is in close contact with the outer surface of the welding bolt 11, scratches the outer surface of the welding bolt 11. The coating material applied to the outer surface of the film is separated from the outer surface of the welding bolt 11.

이에 따라 상기 웰딩 볼트(11)와 마운팅 너트(20)의 결합부 사이를 가로막던 도포재가 제거되어 웰딩 볼트(11)와 마운팅 너트(20)의 전기적 통전성이 향상되게 된다. 그리고, 이러한 마운팅 너트(20)와 웰딩 볼트(11)의 결합에 의하여, 전자장비로부터 접지용 터미널 단자(T)로 인가되는 마이너스(－) 전하가 투스 와셔(12), 마운팅 너트(20), 웰딩 볼트(11) 및 차체(P)를 차례로 경유한 후 공기 중으로 방전되는 전기적 통전성이 향상됨으로써, 전자장비의 접지성이 향상되게 된다.Accordingly, the coating material blocking the coupling portion of the welding bolt 11 and the mounting nut 20 is removed to improve the electrical conductance of the welding bolt 11 and the mounting nut 20. And, by the coupling of the mounting nut 20 and the welding bolt 11, the negative (-) charge applied from the electronic equipment to the ground terminal terminal (T) is the tooth washer 12, the mounting nut 20, Since the electrical conductance discharged into the air after passing through the welding bolt 11 and the vehicle body P in order is improved, the grounding property of the electronic equipment is improved.

상기 일 실시예에 의하여 알 수 있는 바와 같이, 본 발명을 따른 전자장비의 접지용 구조물에 의하여, 마운팅 너트와 웰딩 볼트 사이의 전기적 통전성을 방해하던 도포재를 제거함으로써, 전자장비의 접지성을 향상시킬 수 있으며, 이에 따라 전자장비의 접지불량에 의한 전자장비의 오동작을 방지할 수 있는 효과가 있다.As can be seen by the above embodiment, by the structure for grounding of the electronic equipment according to the present invention, by removing the coating material that prevented the electrical conduction between the mounting nut and the welding bolt, to improve the grounding of the electronic equipment In this way, there is an effect that can prevent the malfunction of the electronic equipment due to the ground fault of the electronic equipment.

이상에서 본 발명의 일 실시예에 따른 전자장비의 접지용 구조물에 대하여 설명하였으나, 본 발명은 이에 한정하지 아니하며, 당업자라면 여러 가지로 그 변형과 응용이 가능할 것이다.Although the structure for grounding of electronic equipment according to an embodiment of the present invention has been described above, the present invention is not limited thereto, and those skilled in the art will be able to variously modify and apply the same.
