Abstract

In a xerographic printing machine, it is commonly known to utilize corotrons and scorotrons to introduce charge potentials to the surface of an electrostatic device. More recently, the charging components have been incorporated into customer replace units (CRU's). To minimize the cost of these CRU's, attention is focussed upon the elimination of parts and simplification of the manufacturing process associated with the individual CRU's.

METHOD OF ASSEMBLING AND TENSIONING COROTRON AND SCOROTRON WIRES AND GRIDS(Cont'd)

In a xerographic printing machine, it is commonly known to utilize corotrons and scorotrons to introduce charge potentials to the surface of an electrostatic device. More recently, the charging components have been incorporated into customer replace units (CRU's). To minimize the cost of these CRU's, attention is focussed upon the elimination of parts and simplification of the manufacturing process associated with the individual CRU's.

Accordingly, the present invention is directed towards a method of assembling a corotron or scorotron device, within a CRU, to minimize the cost of the unit. For example, the figure illustrates a portion of a single wire corotron assembly, having a flexible connector mount 12, with an electrical connector 14 seated therein. Connector 14 has a pin 15 extending therefrom along the longitudinal axis to provide a suitable electrical contact to an electrical receptacle (not shown). Connected to the opposite end of connector 14 is one end of wire 16, the opposite end of which is anchored to a fixed mount 18. Flexible connector mount 12 is formed within a portion of a larger, fixed portion of the corotron assembly, wall 20. Wall 20 and fixed mount 18 are rigidly maintained at a fixed distance from one another by the remainder of the corotron assembly (not shown).

As illustrated in the figur...
