Definitions

  • the present invention relates to the field of ink-jet printing technologies, and in particular, to an ink cartridge chip, an ink cartridge, and an ink-jet printer.
  • a chip for a printer is configured to store manufacturer information, ink volume information, ink cartridge type information, ink color information, and the like.
  • a chip for an ink-jet printer plays a decisive role in normal operation of the ink-jet printer.
  • the Chinese Patent No. 201020599870.2 discloses an ink cartridge chip and an ink cartridge. It can be learned by referring to FIG. 1 and FIG. 2 that, in the prior art, a chip 20 has multiple notches 22, and each notch 22 has an electric-conductor 25.
  • the prior art has the following disadvantages: As a printer and an ink cartridge are miniaturized, a chip also becomes increasingly miniaturized, a gap between terminals of the chip also becomes increasingly small, and a contact pin 7 also becomes increasingly thin. In addition, to better achieve a contact effect between an electric-conductor 25 and the contact pin, a notch 22 and an open end 23 also become increasingly small. Consequently, chip processing difficulty is high (processing of a small and deep groove), an installation precision requirement is high, and during installation, if the chip deviates, the contact pin may not slide into the notch 22, easily causing cases of poor contact of the chip and damage to (bending of) the contact pin.
  • the present invention provides an ink cartridge chip, an ink cartridge, and an ink-jet printer, to resolve a problem existing in the prior art that poor contact of a chip and damage to a contact pin are easily caused.
  • a first aspect of the present invention is to provide an ink cartridge chip.
  • the ink cartridge chip is configured to electrically connect to contact pins in an installation portion, an accommodation groove is provided on the ink cartridge chip, and contact portions configured to come into contact with the contact pins are disposed in the accommodation groove.
  • a second aspect of the present invention is to provide an ink cartridge detachably installed in an installation portion.
  • the ink cartridge includes the foregoing ink cartridge chip, and the ink cartridge chip is configured to engage with contact pins in the installation portion.
  • a third aspect of the present invention is to provide an ink cartridge that can be installed in an installation portion.
  • the ink cartridge includes the foregoing ink cartridge chip.
  • a fourth aspect of the present invention is to provide an ink-jet printer.
  • the ink-jet printer includes the foregoing ink cartridge.
  • an accommodation groove that can accommodate contact pins is provided on the ink cartridge chip, and at least two inner contact portions configured to come into contact with the contact pins are disposed in the accommodation groove, to avoid that during installation of the ink cartridge chip, if the chip deviates, the contact pin may not slide into a notch, easily causing cases of poor contact of the chip and damage to (bending of) the contact pin, and ensure stable and effective contact between the ink cartridge chip and the contact pin, thereby improving use stability and reliability of the ink cartridge chip, and facilitating market promotion and application.
  • first and second are used merely for convenience of description of different components, and should not be construed as indicating or implying a sequenced relationship or relative importance or implicitly specifying a quantity of indicated technical features. Therefore, a feature restricted by “first” or “second” may explicitly indicate or implicitly include at least one of such features.

  • a specific quantity of inner contact portions 201 is not limited.
  • the quantity of inner contact portions 201 may be set to 2, 3, or 4.
  • the width of the accommodation groove 2 may be set to be larger. In this way, a case in which the contact pin 7 is easily broken and cannot be installed in place due to a relatively small accommodation groove 2 during installation can be effectively prevented.
  • two of disposed inner contact portions 201 are disposed to be opposite to each other, so that interference between the two inner connection terminals can be reduced to the greatest extent, thereby ensuring use stability and reliability of the ink cartridge chip 1.

More preferably, the preset angle may be set to 90°. In this way, the inner contact portion 201 is perpendicular to the first plane 101, and during installation of the ink cartridge chip 1, damage caused to the inner contact portion 201 due to scratches is avoided, thereby ensuring a normal use effect of the inner contact portion 201, and further ensuring use stability and reliability of the ink cartridge chip 1.
