A kind of information storaging piece and print cartridge
[technical field]
The present invention relates to printing consumables field, be specifically related to a kind of information storaging piece and the print cartridge of this information storaging piece is housed.
[background technology]
Existing printer and ink box chip have two kinds of connected modes: the electrical connection one, realizing printer and ink box chip with connecting line, connecting line one end electrical connection ink box chip, other end electrical connection printer.This connected mode, because of the existence of connecting line, can increase the purchase cost of consumer; And because of the two ends connected mode of connecting line, compare one end connected mode, product reliability reduces.Two, by arranging connector on a printer, be connected with the electric contact on ink box chip by the splicing ear on connector, as Fig. 1 and Fig. 2, the connector 100 that is electrically connected with ink box chip of EPSON printer setup, this connector contains 9 splicing ears, is divided into height two row splicing ears, i.e. upper row's splicing ear 101 and lower row's splicing ear 102, upper row's splicing ear 101 and lower row's splicing ear 102 uniform intervals are arranged, and the spacing between any two adjacent splicing ears is identical.Upper row's splicing ear 101 comprises front 1012 and the left and right side except front 1012, upper and lower side, such as the right flank 1011 in Fig. 3; Lower row's splicing ear 102 comprises front 1022 and the left and right side except front 1022, upper and lower side, such as the right flank 1023 in Fig. 3, upper side 1021.The electrical contacts 201,202 of ink box chip 200 need be pressed in the outstanding position of the height two row splicing ear of connector 100, also namely with the front 1012 of upper row's splicing ear, the front 1022 of lower row's splicing ear contacts.Upper and lower and the both sides setting accuracy of mode to the electric contact of chip and splicing ear of this front face requires high, otherwise there will be the phenomenon of loose contact.
[summary of the invention]
In view of this, the invention provides the information storaging piece that a kind of structure is improved.
The present invention adopts following technical scheme, tectonic information storaging piece, and described information storaging piece can contact with splicing ear, and it comprises matrix, and is arranged on the multiple electrical contacts on matrix, the contacts side surfaces of electrical contacts described at least one and splicing ear.
Preferably, described information storaging piece is arranged on box body, and along looking perpendicular to described box body installation direction, the contact point of described electrical contacts and splicing ear point-blank.
Preferably, described electrical contacts one end is connected with matrix, and the other end is provided with protuberance.
Preferably, described electrical contacts comprises the first electrical contacts and the second electrical contacts, and described first electrical contacts is at least connected with matrix one end, and described second electrical contacts one end is connected with matrix, and the other end is provided with protuberance.
Preferably, interference fit between described protuberance summit and the side of splicing ear.
Preferably, interference fit between described first electrical contacts and the side of splicing ear.
