Abstract

The utility model relates to a field of printing consumption materials, in particular to a chip that can be communicated with the body of printer, and an ink box where the chip is used. The chip comprises a substrate, an IC arranged fixedly on the surface of the substrate and a group of contact points, the IC is communicated with the contact points; wherein a group of contact points are arranged horizontally along the substrate in single line, the plumb length of each contact point along the substrate is not less than the gap between upper and lower probes of the printer and not more than the length of the substrate. The structure of the chip in the ink box is improved, the prior double-line contact points are changed to single-line contact points, the length of each contact point is longer than that of the contact point of the prior chip, the longer contact point facilitates for good positioning of the contact points and probes when the ink box is assembled into the printer; additionally the lengthened contact points can prevent the contact points from being vertically separated from the probes of printer during printing.

Description

Chip and use the print cartridge of this chip

Technical field

The utility model relates to the printing consumables field, especially a kind of print cartridge that can carry out the chip of communication with printer main body and use this chip.

Background technology

Printer is a kind of common office equipment, for modern office provides great help and convenient.Existing ink-jet printer uses dismountable print cartridge mostly, it is installed on the printer main body, and consumptive material is sent on the recording medium.And on print cartridge, generally all be useful on the chip of stored information (as print cartridge model, date of manufacture, Mo Liang etc.).Chip structure comprises substrate, IC and contact, and wherein contact and IC conduct; When print cartridge was mounted to printer, the contact was connected with probe on the printer, and the probe on the printer is generally 7 or 9, was two rows and distributed, and was generally 3 times 4 or last 4 times 5; Referring to Fig. 1, at present, manyly on the ink-jet printer cartridge chip substrate 100 adopt two rows contact 101 to design accordingly with the printer probe, its design class is like " product " word structure, its chip substrate 100 is installed on the print cartridge sidewall, when the user is installed in print cartridge in the printer prints car, contact on this substrate 100 will be relative with printer probe contact and realize being electrically connected, the contact 101 that this " product " font is arranged is mounted in the process of printer at print cartridge, left and right sides positioning accuracy request height not only, and positioning accuracy requires height too up and down, because of the existence of the relative accumulated error of aforementioned this indirect installation, be difficult to guarantee the reliability that chip contacts 101 can well contact with the printer probe.For solving this type of problem, Chinese patent discloses a kind of chip CN200520066968.0 number, on the surface of this chip a plurality of contacts is arranged, a row is arranged in described contact, and each contact one end is big, and the other end is little, be staggered and arrange, the big end in contact contacts with the printer connection end point.The shortcoming of this chip is: the narrow end width of contact is too little, in packing the process of printer into, print cartridge can't effectively guide the accurate location of ink box chip and printer probe, even may narrow end landing makes the location mistake of ink box chip and printer probe from the contact owing to probe; In addition, the length of this chip contacts is less, is unfavorable for the chip in the print cartridge installation process and the accurate location of probe.

Summary of the invention

First purpose of the present utility model provides a kind of ink box chip that can guarantee contact and printer probe good location;

Second purpose of the present utility model provides a kind of print cartridge that can guarantee contact and printer probe good location.

For realizing above-mentioned first purpose, the utility model provides following technical scheme: chip, comprise substrate, and be fixed on IC and one group of contact on the substrate surface, IC and contact conduct, and described one group of contact laterally is single layout along substrate; Wherein, each contact is not less than up and down probe spacing and be not more than substrate length of printer along the vertical length of substrate.

Described one group of contact is along the vertical equal in length of substrate, and each contact is a rectangle.

Ink box chip structure of the present utility model is improved, with each contact design is rectangle, and the length of each contact all will be grown than the contact of existing chip, and long contact helps print cartridge printer process chips contact and the printer probe good location on vertical of packing into; In addition, the contact behind the lengthening also can prevent the vertical disengaging of contact and printer probe in print procedure.Each contact is promptly compared prior art and is widened in the part from as rectangle, and the contact after widening is the chip guide contraposition better.

For realizing above-mentioned second purpose, the utility model also provides following technical scheme: print cartridge, it comprises ink tank, ink supply port and chip, described chip comprises substrate, be fixed on IC and one group of contact on the substrate surface, IC and contact conduct, and described one group of contact laterally is single layout along substrate; Wherein, each contact is not less than up and down probe spacing and be not more than substrate length of printer along the vertical length of substrate.

Print cartridge of the present utility model improves the chip structure on it, with each contact design is rectangle, and the length of each contact all will be grown than the contact of existing chip, and long contact helps print cartridge printer process chips contact and the printer probe good location on vertical of packing into; In addition, the contact behind the lengthening also can prevent the vertical disengaging of contact and printer probe in print procedure.Each contact is promptly compared prior art and in the part contact is widened from as rectangle, and the contact after widening is the chip guide contraposition better.

The specific embodiment

Embodiment one

Referring to Fig. 2, Fig. 2 has disclosed the structure chart of the utility model ink box chip first embodiment.The ink box chip of present embodiment comprises substrate 1, IC (figure does not show) and contact 11, and IC and contact 11 conduct, and IC and contact 11 all are positioned on the substrate 1.Each contact 11 laterally be arranged in parallel along substrate 1, and laterally is single setting along substrate.Referring to Fig. 3, isometric and its length in each contact 11 is not less than the distance between the upper and

lower probe

32,31 of printer.

Embodiment two

The difference of present embodiment ink box chip and embodiment one is: further extend in the contact 21 on the ink box chip substrate 2, and this contact 21 extends to substrate 2 tops from substrate 2 bottoms on substrate 2 is vertical.Through the chip contacts accurate location that can better realize contact and printer probe behind the lengthening, and the contact can not influence both effective with probe in vertical relative motion yet and contacts.

Embodiment three

Present embodiment is about a kind of ink-cases of printers, print cartridge generally comprises ink tank, ink supply port and chip etc., the main improvements of print cartridge of the present invention are ink box chip, this ink box chip can use any one structure in the foregoing description one to embodiment two.
