본 발명은 내연기관에 사용되는 다수개의 점화코일을 하나의 몸체에 고정하는 센터커버 일체형 점화코일 모듈에 관한 것으로, 더 상세하게는 센터커버들 간의 전압을 직접 전도할 수 있는 전자회로기판을 삽입하여 센터커버들을 하나로 결합하고, 센터커버들과 점호코일은 볼트로 결합하여 착탈이 용이하도록 하는 구조를 갖는 센터커버 일체형 점화코일 모듈에 관한 것이다.The present invention relates to a central cover integrated ignition coil module for fixing a plurality of ignition coils used in an internal combustion engine to one body, and more particularly, by inserting an electronic circuit board capable of directly conducting voltage between the center covers. Combining the center cover as one, the center cover and the firing coil relates to a center cover integrated ignition coil module having a structure that is easy to attach and detach by bolts.

일반적으로, 점화장치는 연소실 내부에 압축된 혼합가스를 연소시키기 위하여 고전압을 만들어 점화 플러그에 스파크를 일으키는 것이다. 통상의 점화장치는 점화플러그와, 점화코일과, 분배기로 구성되는데, 하나의 점화코일에서 발생된 고전압을 하나의 분배기를 통해 모든 점화플러그에 공급하므로 점화코일이나 분배기가 고장나는 경우에는 엔진이 멈추게 되었다.In general, an ignition device sparks a spark plug by creating a high voltage in order to combust the mixed gas compressed in the combustion chamber. A typical ignition device is composed of an ignition plug, an ignition coil, and a distributor. The high voltage generated from one ignition coil is supplied to all the ignition plugs through a single distributor, so that the engine stops when the ignition coil or distributor fails. It became.

최근에는 분배기가 없는 점화장치가 사용되고 있는데, 분배기가 없는 점화장치는 각 실린더마다 하나의 점화코일을 구비하고 각 점화코일들의 내부에 구비된 소형컴퓨터가 각 실린더의 점화시기를 조절할 수 있도록 하는 것으로, 각각의 점화코일의 작동은 다른 점화코일의 작동에 영향을 받지 않으므로 모든 점화코일이 고 장나지 않는 한 엔진이 멈추지 않는 장점을 있다. Recently, an ignition device without a distributor is used. An ignition device without a distributor has one ignition coil for each cylinder, and a small computer provided inside each ignition coil can adjust the ignition timing of each cylinder. The operation of each ignition coil is not affected by the operation of the other ignition coil, so the engine does not stop unless all the ignition coils fail.

한편, 분배기가 없는 점화장치는 각 점화코일에 전력을 공급하는 전압케이블이 각각 필요하므로 배선이 복잡해지고 내구성이 감소되는 문제점이 있다. 와이어 하니스를 사용함으로서 공간상의 제약과 오결선이라는 문제가 발생하였으며, 다수의 코일들과 모듈의 결합이 밀봉과 용접의 방법을 사용함으로서 1개의 코일 파손으로도 모든 코일을 교체해야 하므로 교체시나 유지시에 많은 비용과 시간을 소모하는 문제점을 가지게 되었다.On the other hand, the ignition device without a distributor requires a voltage cable for supplying power to each ignition coil, so there is a problem that the wiring is complicated and durability is reduced. The use of wire harness has caused problems of space limitation and incorrect wiring, and the combination of multiple coils and modules uses the sealing and welding method, so that all coils must be replaced by one coil breakage. Has the problem of costly and time consuming.

이상에서 설명한 바와 같이 본 발명은 센터커버 본체 내부에 삽입된 전자회로기판으로 점화코일과의 결합시 직접적으로 전압을 전달 할 수 있어서 와이어 하니스를 사용하지 않고도 전압의 인가와 결합이 가능하며, 센터커버와 점화코일간 에는 상호 일체형으로 형성하되, 상기 센터커버와 점화코일은 용접이나 밀봉이 아닌 볼트로 결합·고정되어서 착탈이 가능해 교체나 유지시에 비용과 시간을 절감하는 것이 가능하게 되었다.As described above, the present invention is an electronic circuit board inserted into the center cover body, so that the voltage can be directly transmitted when the ignition coil is coupled, and thus the voltage can be applied and coupled without using a wire harness. While the ignition coil is formed integrally with each other, the center cover and the ignition coil are coupled and fixed by bolts, not welded or sealed, and are detachable, thereby reducing costs and time during replacement or maintenance.

또한, 센터커버와 점화코일의 결합은 센터커버 저면의 원형 돌출 삽입부 내면에 전자회로기판과 직접 부착된 접지단자로 쓰여진 스프링이 센터커버 본체의 외측으로 표출되어 점화코일 상단에 돌출 형성된 접지단자와 밀착하여 결합되 진동의 완충과 배전기를 통한 전압을 증폭시켜 주는 기능을 제공하는 것이다.In addition, the combination of the center cover and the ignition coil includes a ground terminal formed on the inner surface of the circular protruding insertion portion of the bottom of the center cover, the spring being written as a ground terminal directly attached to the electronic circuit board to the outside of the center cover body, protruding from the top of the ignition coil. Closely coupled to provide a function to amplify the voltage through the vibration damper and distributor.
