Abstract:
1. An ignitor assembly for an internal combustion engine fuel/air ignition system, comprising: an upper inductor subassembly having a tubular housing extending between an upper end and a lower end with inductor windings received in said housing between said upper and lower ends and having an upper electrical connector adjacent said upper end of said housing and a lower electrical connector adjacent said lower end of said housing, said upper electrical connector being configured in electrical communication with said lower electrical connector via said inductor windings; a lower firing end subassembly having a ceramic insulator and a metal housing surrounding at least a portion of said ceramic insulator, said ceramic insulator extending between a terminal end and a firing end with an electrical terminal extending from said terminal end in electrical contact with said lower electrical connector and an electrode extending from said firing end, said electrode being configured in electrical communication with said electrical terminal; and a non-metal tube connecting said upper inductor subassembly to said lower firing end subassembly and maintaining said electrical terminal in electrical contact with said lower electrical connector, said non-metal tube having an intermediate region extending between said tubular housing of said upper inductor subassembly and said ceramic insulator, said intermediate region being circumferentially unconstrained to allow relative pivotal movement between said electrical terminal and said lower electrical connector.
