Abstract
Abstract Connection of electrical leads to individual charge electrodes in a charge plate structure is facilitated by the formation of conductive pads extending from each charge electrode to the corresponding electrical lead. The conductive pads are formed by applying a mask, containing open areas corresponding to areas between individual charge electrodes and electrical leads, to the charge plate structure and spraying a conductive epoxy resin onto the mask. Electrical connections between the leads and charge electrodes are rapidly and reliably made in this manner.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
In a charge plate for an ink jet printer including a rigid support plate having a medially extending elongated slot, a nonconductive plastic electrode support structure provided with a series of molded charge tunnels having a thickness on the order of at least about 1 mm. and cast in place adheringly against the walls of said slot, charge electrodes coated upon the walls of said tunnels, and electrical lead means attached to said electrodes alternately on opposite sides of said electrode support structure, the improvement comprising: electrically conductive pads adhered to said electrode support structure extending from each of said charge electrodes to each corresponding electrical lead means, electrically connecting each of said charge electrodes to each corresponding electrical lead means.
Claim 2
Dependent Claim
