Abstract: A copier's corona assembly carries arms holding a corona emission wire between a tensioning spring and current limiting resistor. Slugs secure the corona wire to the spring and resistor under tension provided by the arms and the spring while, simultaneously, facilitating a current path through the wire assembly formed by the wire, spring, resistor, and slugs. The slugs, made of a deformable metal receive, in a slot, a corona wire and one lead of the resistor or one end of the spring. A press closes the slot and crimps the slug closed to securely fasten together the wire and the lead or end.
