ABSTRACT:
An electrical igniting element for use with ignitor devices such as are commonly utilized in electrical cigar lighters, engine ignitor plugs, and the like comprises a heating element, such as a wound spiral of resistance ribbon, carried on an annular metal holder or cup and spanning the mouth or opening thereof. The inner end of the spiral ribbon is secured to a central metal stud as by crimping and/or welding it in a slotted head thereof. The invention provides improved means for securing the outer coil convolution to the rim of the holder or cup by curling inward the rim edge into a tight curl which is laid over on the end portions of the coil convolution whereby a relatively large area of the coil end is tightly and securely pinched under continual pressure, thereby establishing a low-resistance effective mechanical and electrical connection between the cup and the coil throughout the useful life of the latter.
