ABSTRACT:
In an ink jet cartridge the platform structure is formed in part by an extension of the bottom of the housing and a forward platform surface intersecting the extension and extending generally perpendicularly thereto. A discharge plate is formed on the platform surface. The discharge plate has one or more rows of ink discharge ports in fluid communication with the ink reservoir. A ink propulsion element is arranged on each of the ink discharge ports. A carrier strip is mounted on the housing. The strip has a forward portion mounted over the platform surface, a rearward portion mounted over the bottom of the housing, and a central portion extending over the intersection of the housing top and the platform surface. A plurality of electrodes are formed on the rearward portion of the carrier strip in an electrode pattern. A plurality of electrically conductive paths are formed on the carrier strip. Each conductive path has a forward end in electrical contact with one of the ink propulsion elements and a rearward end in electrical contact with one of the electrodes. A layer of electrically insulating, heat dissipating, corrosion and oxidation resistant sealant material is injected, placed or otherwise formed between the housing and the carrier strip where exposed. The layer extends beneath the carrier strip from a forward location overlying the platform surface to a rearward location overlying the bottom of the housing, and may include other areas of exposed conductors as well.
