Abstract
An ink jet print cartridge having a compact electrical interconnect structure that includes a plurality of pairs of columnar arrays of electrical contact areas disposed on a front wall of the print cartridge.
Claims61
A print cartridge comprising:
- a cartridge body having a lower portion and a vertical wall;
- a printhead attached to said lower portion;
- a contact array disposed on said vertical wall and including a first outboard pair of columnar arrays of contact areas, a second outboard pair of columnar arrays of contact areas, and an inboard pair of columnar arrays of contact areas the columnar arrays of each pair diverging from each other in a direction toward said bottom portion;
- and
- said pairs of columnar arrays being side by side, and each pair spanning at least 70% of a height of a region occupied by said contact array.
