Ink cartridge chip, ink cartridge and ink-jet printer

Abstract

The invention provides an ink cartridge chip, an ink cartridge and an ink-jet printer. The ink cartridge chip comprises a chip base plate, a chip base and a plurality of chip base contact pins, wherein a plurality of chip contact points which are linearly distributed are arranged on the chip base plate; the chip base plate is mounted on the first side wall of the chip base; a contact pin positioning slot is formed in the second side wall of the chip base; the contact pin positioning slot is used for accommodating a contact part of the ink cartridge chip; the chip base contact pins are of sheet-shaped structures made of a metal material; the chip base contact pins are mounted on the chip base; and each chip base contact pin comprises an inner contact pin and an outer contact pin which are electrically connected, wherein the inner contact pin is arranged on the first side wall of the chip base, the inner contact pin is electrically connected with the corresponding chip contact point, theouter contact pin is arranged on the second side wall of the chip base, and the outer contact pin is electrically connected with a printer contact pin connecting part. The invention further disclosesthe ink cartridge equipped with an ink cartridge chip assembly and the ink-jet printer. The ink cartridge chip assembly is beneficial for prolonging the service life of the ink cartridge and improving durability of the ink cartridge; and moreover, contact pins can be precisely connected.

Description

technical field [0001] The invention relates to the field of printing, in particular to an ink cartridge chip, 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, and device code, and also stores variable data that ...

AI Technical Summary

Problems solved by technology

[0008] When the needle-shaped contact pin 11 on the chip seat is deformed, the electrical contacts on the ink cartridge chip assembly cannot be effectively connected with the printer contact pin, causing the printer to fail to recognize the ink cartridge; and it is easy to make the two contact pins 11 contact, resulting in Electronic components on the chip substrate are damaged due to short circuits

In addition, the structure of the chip holder 12 near the bottom of the ink cartridge is flat, so that after the ink cartridge is dropped, the chip holder 12 presses the printer stylus, causing the entire printer stylus to be deformed under pressure, so that the needle-like contact pin 11 on the chip holder 12 is easy to The contact pin of the printer cannot be effectively connected, causing the printer to fail to recognize the ink cartridge
