ABSTRACT:
An improved method for fabricating electrode structures, particularly flame-front sensors, spark plugs and the like, wherein the center electrode, the insulating housing therefor, and an outer housing are dimensioned such that a small clearance space is provided between each of the parts; a fluid glue is inserted in the clearance or spacing provided in a fixation zone at one end of the structure by capillary action, so that the device is self-centering and heat sealed and not more than 3 mm in diameter, thus facilitating quick and easy installation in engine cylinder heads and combustion chambers.
