Abstract:
An igniter, such as a corona igniter for an internal combustion engine, and a method of manufacturing the igniter, are provided. The igniter includes an insulator with enlarged upper and lower end regions extending axially beyond opposite ends of a constrained, reduced diameter region of a shell through passage. The enlarged lower end region of the insulator is disposed axially outwardly of a lower end of the shell. The insulator is hermetically sealed to the shell and is permanently fixed against being removed axially outwardly from the shell. The method can include conforming the shell to the contour of the insulator by plastically deforming the shell, or casting the shell about the insulator. Alternatively, separate pieces of metal can be disposed around the insulator to form the shell which is conformed to the insulator.

Claim (Index 1):
A corona igniter, comprising:\n an insulator surrounding a central electrode; said insulator having an insulator outer surface including an insulator intermediate region between an insulator upper end region and an insulator lower end region; said insulator intermediate region having a maximum first diameter ID 1 , said insulator upper end region having a minimum second diameter ID 2 , and said insulator lower end region having a minimum third diameter ID 3 , wherein said minimum second diameter ID 2  and said minimum third diameter ID 3  are both greater than said maximum first diameter D 1 ; a shell formed of metal surrounding said insulator; said shell having a shell outer surface including a threaded region with a plurality of threads; said shell having a shell inner surface including a shell lower end region radially aligned with said threaded region; said shell lower end region having a maximum inner diameter SD 1  which is less than said minimum second diameter ID 2  and said minimum third diameter ID 3  of said insulator outer surface; said shell being plastically deformed such that said shell inner surface conforms with the contour of said insulator intermediate region; and said insulator lower end region extending axially outwardly from a shell lower end of said shell.
