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.

Corona wire assembly and method

A corona wire, either directly or through an auxiliary element, engages the spiral thread of a screw-like stub member mounted on the housing of a corona charging apparatus to provide a simple, low cost and easily assembled corona wire adjuster. The stub member is mounted on the housing such that it may be rotationally driven much like a screw, but, unlike a screw, will not move into or out of the housing as it is rotated. Rotation of the stub member causes the corona wire to move in a direction parallel to the stub member axis in response to the thread engagement and thereby change its position relative to a photoconductor surface.
