Ink box chip, ink box and ink-jet printer

Abstract

The invention provides an ink box chip, an ink box and an ink-jet printer. The ink box chip comprises a chip substrate. An electronic module is installed on the chip substrate. A chip contact assembly electrically connected with the electronic module is arranged on the substrate and comprises a plurality of chip contacts, wherein the chip contacts are linearly distributed, a contact part is arranged at the outermost end of each chip contact, and the contact parts are located at the joints of contour lines of protrusion parts located on the upper row printer contact probes in the projection direction of the side wall of upper row printer contact probes and contour lines of protrusion parts located on lower row printer contact probes in the projection direction of the side wall of the upper row printer contact probes. The ink box is provided with the ink box chip, and the ink-jet printer is provided with the ink box. The chip contacts are respectively electrically connected with the upper ends and the lower ends of the printer contact probes, the mutual acting force between the chip contacts and the printer contact probes is minimum when the chip contacts make contact with the printer contact probes, and therefore the printer contact probes are protected from damage, and production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of printing, in particular to an ink cartridge chip installed with upper and lower electrical contacts, an ink cartridge equipped with the ink cartridge chip, and an inkjet printer equipped with the aforementioned ink cartridge. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers mainly include ink-jet printers. Ink-jet printers use ink cartridges containing ink to be installed on character carriages to form characters or patterns to be printed on recording media such as paper. [0003] The shell of the ink cartridge is mostly equipped with an ink cartridge chip. When the ink cartridge is installed in an imaging device such as a printer or a copier, the ink cartridge chip can exchange information with the printer or copier. The memory of the ink cartridge chip generally stores fixed information such as the production date, manufacturer, a...

Problems solved by technology

[0010] However, the printer stylus on the stylus mechanism 3 is electrically contacted with the electrical contacts 21 on the ink cartridge chip 2 due to the hook-shaped copper sheet that is used in all, so every time the ink in the ink cartridge is exhausted, it needs to be removed from the ink cartridge. To replace the ink cartridge on the computer, because the structure of the printer stylus is complex and thin, it is easy to cause the printer stylus to break or deform during the replacement process. After the stylus is damaged, it needs professionals to repair it, which causes a lot of inconvenience to the user and also to the user. Personnel increase the cost of use
