Abstract: A reliable mechanical and electrical connection is formed between a slotted rivet and an insulated ground wire using a minimum number of manual steps. The slotted rivet head has two spaced, opposed, semi-frustoconical sections that define a slot between them. The slotted rivet is placed and properly aligned in a coil frame, and the ground wires are placed into the slot. The rivet head is then deformed by an orbital riveter to capture a portion of the insulated wire within the rivet head. A resistive welder engages the rivet head to vaporize the insulation from the captured wire portion without touching the wire. The resulting terminal assembly has a unique design in which the deformed rivet head is substantially flat.
