Printer

Abstract

The invention discloses a printer, which comprises a carriage unit. The carriage unit is connected with a printer belt and is mounted with a nozzle boss with an ink box in a connected manner, a carriage unit circuit board is clamped between the nozzle boss and the carriage unit, a first flat cable slot and a second flat cable slot are disposed on the carriage unit circuit board, a first data flat cable is plugged in the first flat cable slot, the other end of the first data flat cable is attached onto a spray orifice at the bottom of the nozzle boss, and a second data flat cable which is connected with a printer mainboard is plugged in the second flat cable slot. An existing connection mold that a carriage unit is electrically connected with a carriage unit circuit board by the aid of butting contact of a reed connector and a contact strap is abandoned, the problem that the carriage unit circuit board and the printer mainboard are burned due to the fact that ink stains contacts when a user changes components such as the nozzle boss and the like is avoided, and the printer is simple and reasonable in structure and low in process cost.

Description

technical field [0001] The invention relates to a printer, in particular to a printer in which a nozzle seat is connected to a character car circuit board through a data cable. Background technique [0002] As a common office equipment, inkjet printers provide great convenience for modern office. Most of the existing printers transmit the printing signal to the word car circuit board through the main board of the printer, and the word car circuit board sends the printing signal to the nozzle seat, to control the function of the nozzles on the nozzle seat to spray ink dots on printing media such as paper to form characters or patterns that need to be printed. In the traditional inkjet printer, the connection between the print head seat and the word car circuit board is mainly realized by the reed connector and the contact belt. This connection structure is due to the conflicting contact between the contact and the reed connector. Yes, and the number of contacts is large, it ...

AI Technical Summary

Problems solved by technology

In the traditional inkjet printer, the connection between the print head seat and the word car circuit board is mainly realized by the reed connector and the contact belt. This connection structure is due to the conflicting contact between the contact and the reed connector. Yes, and the number of contacts is large, it is easy to have poor contact of some contacts, and it is also prone to misalignment between each contact and the reed connector, which will cause the printer to be unable to perform printing work and seriously affect printing. In addition, when the nozzle seat and other parts are damaged and need to be replaced, if the ink is accidentally stained on the contacts during the operation, once the printer is powered on, the word car circuit board connected to the contacts and the word car circuit board will be damaged. The mainboard of the connected printer will be burned, which makes the printer very risky during disassembly

At the same time, use the contact strip and the reed connector to connect the word car circuit board and the nozzle seat, because the cost of the reed connector is high and the requirements for the contact strip technology are high, which greatly increases the production process cost of the entire printer, which is not conducive to Further promotion of inkjet printers
