Detailed description of the invention
Ink box chip of the present utility model is arranged on the print cartridge of ink-jet printer use, receives the signal of ink-jet printer output, and returns to corresponding signal according to the signal of ink-jet printer output to ink-jet printer.
If ink-jet printer is color inkjet printer, multiple print cartridges are installed on ink-jet printer, an ink box chip is all installed on each print cartridge; If ink-jet printer is black and white ink-jet printer, a black print cartridge is only installed on ink-jet printer, print cartridge has a housing, housing surrounds a cavity, the lower end of cavity is provided with ink outlet port, ink in cavity can flow out through ink outlet port, and is injected in and on paper, forms required word and pattern.
An ink box chip is installed on the housing of print cartridge, and each piece ink box chip all has a substrate, and the first surface of substrate is provided with multiple electric contacts, and for being connected with the electric contact of ink-jet printer, the another side of substrate is provided with electronic module.
The electric contact of ink box chip comprises an earthing contact, a power contact and two detection contacts, earthing contact is electrically connected with the earthing contact of ink-jet printer, power contact is electrically connected with the power contact of ink-jet printer, and receives the direct current of ink-jet printer output.
Referring to Fig. 6, second of substrate 40 is provided with electronic module 40, electronic module 40 has controller and memory, controller can be used for the data read-write operation of control storage, memory stores has such as print cartridge model, the applicable data such as ink-jet printer model, ink surplus of print cartridge, also be provided with the identification code data of print cartridge, the ink color that normally print cartridge holds.
And, substrate 40 is provided with multiple via holes, as via hole 42,43,44,45 etc., the power line being connected with earthing contact is through via hole 42, and be electrically connected with the first end of resistance R 1, the second end of resistance R 1 is electrically connected with the earth terminal GND of electronic module 40, and therefore resistance R 1 is connected between earthing contact and the earth terminal GND of electronic module 40.
Preferably, the resistance of resistance R 1 is greater than the resistance of the power line between earthing contact and the earth terminal of electronic module, and the resistance of resistance R 1 is more than or equal to 50 Europe, to guarantee the dividing potential drop effect of resistance R 1.
The power line being connected with power contact is electrically connected with the power end VCC of electronic module 40 through via hole 45, the power line being electrically connected with a detection contact passes via hole 43 and is electrically connected with the earth terminal GND of electronic module 40, and the power line being electrically connected with another detection contact passes via hole 44 and is electrically connected with electronic module 40.
Referring to Fig. 7, the power end VCC of electronic module 40 receives the DC signal that ink-jet printer provides, and earth terminal GND is electrically connected with earthing contact 51 by resistance R 1, and earth terminal GND is connected directly to detection contact 52.Once electronic module 40 is subject to inkiness and causes power end VCC and earth terminal GND short circuit, electric current will flow to earthing contact 51 through the earth terminal GND resistance R 1 of flowing through, therefore in resistance R 1, form higher voltage, the electric current of earthing contact of flowing through is limited by resistance R 1, can not cause between the earthing contact of ink-jet printer and power contact and flow through larger electric current, avoid ink-jet printer to cause damage.
And detecting contact 52 is not to be directly connected with the earthing contact of ink-jet printer, but is connected to the earthing contact of ink-jet printer by resistance R 1.In addition, be still owing to detecting contact 52 the earth terminal GND that is connected to electronic module 40, can not have influence on ink-jet printer to detecting the testing of contact.
The variations such as the change of each electric contact position on the change of the resistance of resistance R 1, substrate finally it is emphasized that the utility model is not limited to above-mentioned embodiment, as also should being included in the protection domain of the utility model claim.
