Abstract

[목적][purpose]

본 발명은 엔진의 각 실린더에 하나씩 설치되어, 점화코일에서 발생한 고압전류를 중심전극에 받아 접지전극과의 간극인 스파크 캡에 불꽃을 발생시켜 실린더의 연소실에서 압축된 혼합 가스를 점화시키는 스파크 플러그에 관한 것으로, 특히, 중심전극과 스파크 캡을 이루는 접지전극을 중심전극의 중심선상 내부에 일체로 결합함과 동시에 중심전극과의 사이에 결합부위에 절연부재를 내삽하고, 그 선단부를 동심원상의 디스크 형상으로 형성하여 스파크의 발생시 상기 디스크에 의해 대칭적으로 발생되도록 함으로써, 혼합 가스의 점화성을 향상시킬 수 있는 자동차용 스파크 플러그에 관한 것이다.The present invention relates to a spark plug which is installed in each cylinder of an engine and generates a spark on a spark cap which is a gap with a ground electrode by receiving a high-voltage current generated in an ignition coil by a center electrode and ignites a gas mixture compressed in a combustion chamber of a cylinder And more particularly to a structure in which a ground electrode constituting a center electrode and a spark cap are integrally connected to the inside of a center line of a center electrode and an insulating member is inserted into a joint portion between the center electrode and the center electrode, And the spark is symmetrically generated by the disk when the spark occurs, thereby improving the ignitability of the mixed gas.

[구성][Configuration]

중심선상 내부에 동심원상으로 일정한 깊이를 갖으며 결합홈이 구비되는 중심전극과, 상기 결합홈과 대응하는 몸체부가 구비되고, 그 선단부로 디스크 형상의 전극부가 일체로 형성되는 접지전극과, 상기 접지전극과 중심전극 사이의 결합부위에 내삽되어 일체화 되는 절연부재로 구성된다.A ground electrode having a central electrode having a constant depth in a concentric circle on a center line and provided with an engaging groove, a body portion corresponding to the engaging groove, and a disc-like electrode portion integrally formed at a distal end thereof; And an insulating member which is inserted and integrated with a coupling portion between the electrode and the center electrode.
