ABSTRACT:
An improved igniter and cable connector assembly for turbine engines. An igniter mounting adapter is secured to the engine. The igniter slides into a hole through the adapter and is retained by an enlarged head on the igniter. An annular seal is positioned around a high voltage terminal on the igniter head and a terminal on the cable connector is positioned against the igniter terminal. The cable connector is secured to the adapter, for example, by either a clamp assembly or a coupling nut or a quick release connector. As the cable connector is secured to the adapter, the seal is compressed between the igniter and connector insulators and, optionally, the connector terminal is rotated and pressed against the igniter terminal to establish a reliable electrical contact. The connector and igniter terminals preferably have mating conical or spherical surfaces, one of which may be an annular segment to provide an increased electrical contact area.
