Abstract

This utility model relates to the field of printing consumables, and in particular to a chip capable of communicating with the printer body and an ink cartridge using this chip. The chip includes a substrate, an IC fixed on the surface of the substrate, and a set of contacts, the IC and the contacts being electrically connected; wherein the set of contacts is arranged in a single row along the transverse direction of the substrate, and the length of each contact along the vertical direction of the substrate is not less than the distance between the upper and lower probes of the printer and not greater than the length of the substrate. The ink cartridge chip structure of this utility model is improved by designing the original double-row contacts as a single row, and the length of each contact is longer than that of contacts in existing chips. The longer contacts facilitate better positioning of the chip contacts and the printer probes during ink cartridge insertion into the printer; in addition, the extended contacts also prevent vertical detachment of the contacts from the printer probes during printing.

Description

Chip and ink cartridge using the chip

technical field

The utility model relates to the field of printing consumables, in particular to a chip capable of communicating with a printer main body and an ink cartridge using the chip.

Background technique

Printer is a kind of common office equipment, which provides great help and convenience for modern office. Most of the existing inkjet printers use detachable ink cartridges, which are installed on the main body of the printer, and the consumables are delivered to the recording medium. On the ink cartridge, there is generally a chip for storing information (such as the ink cartridge model, production date, ink volume, etc.). The chip structure includes a substrate, IC and contacts, wherein the contacts and IC are electrically connected; when the ink cartridge is installed in the printer, the contacts are connected to the probes on the printer, and the probes on the printer are generally 7 or 9 in the form of Two rows of upper and lower rows, usually upper 3 lower 4 or upper 4 lower 5; see Figure 1, at present, inkjet printer ink cartridge chip substrate 100 is designed with upper and lower two rows of contacts 101 corresponding to printer probes, and its design is similar to The structure of "pin" character, its chip substrate 100 is installed on the side wall of the ink cartridge, when the user installs the ink cartridge in the printing car of the printer, the contacts on the substrate 100 will contact with the probes opposite to the printer to realize electrical connection, which means In the process of installing the ink cartridge to the printer, the contacts 101 arranged in the shape of "pin" not only require high positioning accuracy from left to right, but also require high positioning accuracy from top to bottom. Due to the existence of relative cumulative errors in the aforementioned indirect installation, it is difficult to Ensure the reliability that the chip contacts 101 can make good contact with the printer probes. In order to solve such problems, Chinese Patent No. CN200520066968.0 discloses a chip. There are multiple contacts on one surface of the chip. The contacts are arranged in a row, and each contact is large at one end and small at the other end. , in a staggered arrangement, the big end of the contact is in contact with the printer connection terminal. The disadvantage of this kind of chip is: the width of the narrow end of the contact is too small, and it cannot effectively guide the accurate positioning of the ink cartridge chip and the printer probe during the process of loading the ink cartridge into the printer, and may even cause the probe to slip from the narrow end of the contact. The positioning of the ink cartridge chip and the printer probe is wrong; in addition, the length of the contact point of the chip is small, which is not conducive to the accurate positioning of the chip and the probe during the ink cartridge installation process.

Contents of the invention

The first purpose of the utility model is to provide an ink cartridge chip capable of ensuring good positioning of the contacts and printer probes;

The second purpose of the utility model is to provide an ink cartridge that can ensure good positioning of the contacts and printer probes.

In order to achieve the above-mentioned first purpose, the utility model provides the following technical solutions: the chip includes a substrate, an IC fixed on the surface of the substrate and a group of contacts, the IC and the contacts are electrically connected, and the group of contacts is arranged along the lateral direction of the substrate. Arranged in a single row; wherein, the vertical length of each contact along the substrate is not less than the distance between the upper and lower probes of the printer and not greater than the length of the substrate.

The set of contacts have the same length along the vertical direction of the substrate, and each contact is rectangular.

The chip structure of the ink cartridge of the utility model has been improved, and each contact is designed as a rectangle, and the length of each contact is longer than that of the existing chip, and the longer contact is beneficial to the process of loading the ink cartridge into the printer Good vertical positioning of the chip contact and the printer probe; in addition, the extended contact can also prevent the vertical detachment of the contact and the printer probe during the printing process. Each contact itself is rectangular, that is, it is locally widened compared with the prior art, and the widened contacts can better guide chip alignment.

In order to achieve the above-mentioned second purpose, the utility model also provides the following technical solutions: an ink cartridge, which includes an ink container, an ink supply port and a chip, and the chip includes a substrate, an IC and a group of contacts fixed on the surface of the substrate, and the IC and The contacts are electrically connected, and the set of contacts is arranged in a single row along the lateral direction of the substrate; wherein, the vertical length of each contact along the substrate is not less than the distance between the upper and lower probes of the printer and is not greater than the length of the substrate.

The set of contacts have the same length along the vertical direction of the substrate, and each contact is rectangular.

The ink cartridge of the utility model has improved the structure of the chip on it, and each contact is designed as a rectangle, and the length of each contact is longer than that of the existing chip, and the longer contact is beneficial to the ink cartridge. Good vertical positioning of the chip contact and the printer probe during the process of entering the printer; in addition, the extended contact can also prevent the vertical separation of the contact and the printer probe during the printing process.
