Abstract

입력/압 리 점화코일(1)은 스파크 플러스에 직접 설치된 원통형케이스(100)를 지닌다. 케이스(100)는 일차스폴(514) 주위에 감긴 일차코일(516)과 이차스플(510) 주위에 감긴 이차코일(512)과 다수의 자기회로부터 (502), (504), (506)을 포함하고 변성기(5)를 수용한다. 이차스폴과 이차스폴은 지지부재(514a,510a)를 지닌다. 조립의 자기회로 부재가 스풀사이에 자동적으로 보지된다. 스풀은 자기회로 부재와 코일으 상부의 일차코일의 리이드 사이에 배설된 절연부재(514f,510f)를 지니어 이차코일과 일차코일에 연결된 부재 사이의 크립패이지 거리를 증가시킨다.The input / pressure ignition coil 1 has a cylindrical case 100 installed directly on the spark plus. The case 100 is configured to remove (502), (504), and (506) from the primary coil 516 wound around the primary pole 514 and the secondary coil 512 wound around the secondary spun 510 and a plurality of magnetic assemblies. And house the transformer 5. The secondary poles and secondary poles have support members 514a and 510a. The magnetic circuit member of the assembly is automatically held between the spools. The spool increases the creep page distance between the linear secondary coil and the member connected to the primary coil with the insulating members 514f and 510f disposed between the magnetic circuit member and the lead of the primary coil above the coil.
