Connecting piece, consumable chip, consumable container, electronic imaging equipment and method for installing connecting piece and consumable container

Abstract

The invention provides a connecting piece, a consumable chip, a consumable container, an electronic imaging device and a method for installing the connecting piece and the consumable container. The connecting piece comprises at least two contact parts, the at least two contact parts are electrically connected with first function contact pins corresponding to the electronic imaging device respectively, the first function contact pins are detection contact pin, the at least two contact parts electrically connected with the first functional contact pins are electrically connected through electric conduction parts, and / or the at least two contact parts are electrically connected with second functional contact pins corresponding to the electronic imaging equipment respectively, the second functional contact pins are the contact pins which apply high-voltage signals, and the plurality of contact parts electrically connected with the second functional contact pins are electrically connected through the electric conduction parts. The consumable chip is arranged on the consumable container, and the consumable container is installed on the electronic imaging device. The invention further provides the method for installing the connecting piece and the consumable container to the electronic imaging equipment. According to the invention, the situation that a memory on the consumable chip is damaged due to the fact that the memory is loaded with the high-voltage signals can be avoided.

Description

technical field [0001] The present invention relates to the technical field of electronic imaging, in particular to a connector, a consumable chip used in conjunction with the connector, a consumable container and an electronic imaging device, and a method for installing the connector and the consumable container. Background technique [0002] As common office equipment, electronic imaging equipment provides great convenience for modern office. Common electronic imaging equipment includes printers, copiers, etc. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink The ink cartridge used as the ink cartridge ejects ink to the paper to form the text or pattern to be printed on the paper; the laser printer uses the toner cartridge containing the toner as the ink cartridge to form the text or pattern to be printed on the medium. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is sho...

Problems solved by technology

Usually, it often takes a few milliseconds from detecting that the level of the detection terminal 21 is too high to disconnecting the power supply of the high-voltage terminal 25, which may cause damage to the memory

In addition, once the detection terminal 21 is abnormal, or the detection circuit is abnormal, and the high-voltage terminal 25 and the connection terminal 26 are not detected in time when the high-voltage terminal 25 is short-circuited, it is easy to cause the memory to be loaded with an excessively high voltage for a long time and cause storage damage. Therefore, the substrate The main cause of memory damage is that the power terminal on the 20 is loaded with excessive voltage

[0020] In addition, due to the short distance between the detection terminals 21, 24 and the high voltage terminals 25, 29, it is easy to cause false detection problems. The connection terminal 26 may still not be short-circuited, but in this case the control circuit 30 will still judge that there is an abnormal situation, and send an abnormal alarm, which will affect the normal operation of the inkjet printer
