Embodiment 1

[0045] Such as Figure 4 and Figure 5 , the information storage element in this embodiment includes a sheet-shaped substrate 11 , at least one first electrical contact portion 12 and at least one second electrical contact portion 13 disposed on one surface of the substrate. The first electrical contact part 12 and the second electrical contact part 13 are made of elastic conductors, and the conductor material may be metal such as copper, beryllium copper or gold. The number of first electrical contact parts 12 is the same as the number of connecting terminals 102 in the lower row of the printer; the number of second electrical contact parts 13 is the same as the number of connecting terminals 101 in the upper row of the printer. A second electrical contact portion 13 is provided between every two first electrical contact portions 12 , and the first electrical contact portion 12 and the second electrical contact portion 13 are arranged in a row.

Embodiment 2

[0051] Such as Figure 8 , the information storage element in this embodiment includes a sheet-shaped substrate 21, and at least one electrical contact portion 22 is provided on one surface of the substrate. The electrical contact part 22 is made of an elastic conductor, and the conductor material can be metal such as copper, beryllium copper or gold. The electrical contact portions 22 are evenly spaced and distributed in a row, and the number thereof is the same as the total number of connecting terminals in the upper and lower rows of the printer.

[0052] The structure of the electrical contact portion 22 is the same as that of the second electrical contact portion 13 in the first embodiment, which is L-shaped and includes a vertical bar 221 and a horizontal bar 222 . Longitudinal bar 221 is arranged perpendicular to the surface of base body 21, and its one end is fixedly connected with base body 21, and its other end is fixedly connected with cross bar 222; The protrusio...

Embodiment 3

[0055] Such as Figure 9 , the information storage element in this embodiment includes a sheet-shaped substrate 31 , and a first electrical contact portion 32 and a second electrical contact portion 33 disposed on one surface of the substrate 31 . The first electrical contact part 32 is in the shape of a long rectangular parallelepiped and fixed on one surface of the base body 31 in an array. The structure of the second electrical contact part 33 is the same as that in the first embodiment.

[0056] The contact positions of the first electrical contact portion 32 and the second electrical contact portion 33 with the upper row of connecting terminals 101 and the lower row of connecting terminals 102 are the same as those in the first embodiment.

Abstract

The invention relates to an information storage part and an ink box provided with same. The information storage part can be connected with a connector which is equipped with upper connecting terminals and lower connecting terminals; the information storage part comprises a basal body as well as a first electric contact part and a second electric contact part which are arranged on the basal part; when the information storage part is connected with the connector, the first electric contact part is in contact with the upper side surfaces of the lower connecting terminals and the second electric contact part is in contact with the side surfaces of the upper connecting terminals; and by virtue of a mode that a first electric contact is in contact with the upper side surfaces of the connecting terminals on the lower row and a second electric contact is in contact with the side surfaces of the connecting terminals on the upper row, positioning precision requirements for the electric contact of a chip, the connecting terminals on the upper row and the connecting terminals on the lower row are greatly reduced, so that bad contact between the electric contact of the chip and the connecting terminals on the upper row and the connecting terminals on the lower row is effectively avoided.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to an information storage part and an ink cartridge equipped with the information storage part. Background technique [0002] There are two ways of connecting the existing printer and the ink cartridge chip: 1. The electrical connection between the printer and the ink cartridge chip is realized with a connecting wire, one end of the connecting wire is electrically connected to the ink cartridge chip, and the other end is electrically connected to the printer. Due to the existence of the connecting wire, this connection method will increase the purchase cost of the consumer; and because the two ends of the connecting wire are connected, compared with the one-end connection method, the product reliability is reduced. 2. By setting up a connector on the printer, the connection terminals on the connector are connected to the electrical contacts on the ink cartridge chip, such as fig...
