发明名称 Wiping structure for cleaning electrical contacts for a printer and ink cartridge.
摘要 <p>An apparatus and method for providing proper electrical contact between corresponding interconnect pads (61, 85) of a print cartridge (24, 25, 26 or 27) and a print carriage (30) are disclosed. One end (91) of a flexible insulating tape (87) including interconnect pads (85) of the print carriage (30) is attached to one side of the print carriage (30) while the other end (92) of the flexible insulating tape (87) may be substantially free or attached to an opposing side of the print carriage (30). When the print cartridge (24, 25, 26 or 27) is initially inserted into the print carriage (30), a gimbal spring (106) causes the flexible insulating tape interconnect pads (85) to preliminarily come in contact with the print cartridge interconnect pads (61) before the print cartridge (24, 25, 26 or 27) is completely inserted. As the print cartridge (24, 25, 26 or 27) is further inserted, the print cartridge (24, 25, 26 or 27) pushes out any excess slack in the flexible insulating tape (87) while providing a wiping action between the interconnect pads (61, 85) of the print cartridge (24, 25, 26 or 27) and the print carriage (30). This wiping action between the interconnect pads (61, 85) scrapes away any contaminants and corrosion, thus ensuring reliable electrical contact.</p>
