Abstract

The utility model relates to consumables used for an ink-jet printer, in particular to an ink box used for an ink-jet printer and a chip used thereon. The ink box comprises an ink tank, an ink supplying port and a chip. The chip comprises a substrate, an IC and a contact, wherein the IC and the contact are eclectically connected to each other and both positioned on the substrate, and the surface of the substrate in the contact zone is a two-dimensional curved surface. The substrate of the chip inside the ink box is designed to have the curved surface in the contact zone, so that when the ink box is mounted in the printer, the contact between the printer probe and the chip contact is line contact instead of point contact in prior art. Therefore, the contact area between the printer probe and contact of the chip is increased, so as to ensure good electrical contact between the chip and the printer and to overcome the problem that the printer fails to identify the ink box and results in abnormal print.

Description

Chip and ink box with same

Technical Field

The utility model relates to a consumptive material that ink jet printer used especially relates to an ink horn that ink jet printer used and the chip that uses on it.

Background

At present, most of ink cartridges used by various ink jet printers in the market are provided with a chip for storing relevant information of ink, the relevant information of ink is provided through the chip, for example, the chip records the ink surplus, when the chip records that the ink is exhausted, the printer prompts that the ink is used up, and the printing is interrupted. The chip is typically mounted on the outer surface of the cartridge in a position corresponding to the printer probe. The printer probes are typically seven (three on top, four on bottom) or nine (four on top, five on bottom), with contacts on the chip corresponding in number and location to the printer probes, making electrical connections in operation. A more conventional chip is shown in fig. 1 and generally comprises a substrate 1, an IC (not shown) and contacts 2 for electrically connecting the IC. The base plate 1 is provided with a plurality of positioning holes 3 for realizing the positioning of the base plate 1 and the ink box main body. The contacts of this type of chip are in two rows. The substrate 1 is a flat plate having a rectangular cross section. Printer probe is mostly the elastic conductor of ridge shape, and when the ink horn was adorned into the printer, printer probe's peak and 2 contacts of contact, because the peak area of probe is less, consequently, printer probe is not good with the contact stability of contact, and the stability of electricity connection is not good promptly, and then influences the discernment of printer to the ink horn, leads to the printer can't print.
