FLEXIBLE IGNITOR ASSEMBLY FOR AIR/FUEL MIXTURE AND METHOD OF CONSTRUCTION THEREOF

摘要

An ignitor assembly constructed in accordance with one aspect of the invention has an upper inductor subassembly coupled to a lower firing end subassembly for relative pivot movement between the subassemblies. The upper inductor subassembly includes a tubular housing with inductor windings received therein with an upper electrical connector adjacent an upper end of the housing and a lower electrical connector adjacent a lower end of the housing. The lower firing end subassembly includes a ceramic insulator and a metal housing surrounding at least a portion of the ceramic insulator. The ceramic insulator has an electrical terminal extending from a terminal end and an electrode extending from a firing end. A flexible tube couples the upper inductor subassembly to the lower firing end subassembly and maintains the electrical terminal of the lower firing end subassembly in electrical contact with the lower electrical connector of the upper at a pivot joint.
