Preferably, the inclined surface 111f is parallel to the bottom of the stepped groove 121f, i.e., the first acute angle is equal to the second acute angle α.

Because the inner sides of the groove walls on the two sides of the groove 11f are smoothly arranged, when the ink bag is installed in the printer, the matching limit of the device terminal group of the printer and the box terminal group of the ink bag in the Z direction of the height direction disappears, the stability of the device terminal group is reduced, when more ink is stored in the ink bag, the ink bag drives the base 1f to slightly incline backwards through the connector 2c under the action of gravity, the contact surface of the box terminal group also inclines backwards, and the upper row terminal of the box terminal group cannot contact with the device terminal group due to insufficient height, so that the problem of poor contact between the device terminal group and the box terminal group occurs.

The connector 2c is provided with a positioning groove on the outer side of the liquid discharge passage 21c, and the positioning groove is cooperatively connected with the limit stopper 194 to restrict the movement of the connector 2c in the Y direction. The connector 2c is further provided with three ribs 22c, and a strip-shaped groove is formed between two adjacent ribs 22 c. The three ribs 22c are inserted into the first avoidance groove 197, the second avoidance groove 198 and the third avoidance groove 200, respectively.

Inkjet printing apparatus embodiment

The present embodiment provides an inkjet printing apparatus including a printing apparatus and the ink bag of any one of the above embodiments. During installation, the device terminal group of the printing device is inserted into the groove along the guide part by integral pushing, and the positioning of the device terminal group in the X direction is realized under the action of smooth groove walls at two sides of the groove; and then the device terminal group slides upwards along the inclined plane, so that the device terminal group is in electrical contact with the chip on the chip mounting position, and the printer can recognize the stored information in the chip.

In summary, the inner sides of the groove walls on two opposite sides of the groove are smoothly arranged, the clamping action of the groove walls on two sides is utilized to fix the device terminal group, even if the shape of the device terminal group or the shape of the flange part is changed, the positioning can be realized as long as the width of the device terminal group is matched with the width of the groove, the device terminal group is favorable for being compatible with device terminal groups with various structures in different shapes, and the device terminal group has the advantages of simple structure and good universality; the guide part is arranged, so that the insertion operation of the device terminal group is convenient, and the guide function is realized, so that the center line of the device terminal group is aligned with the center line of the groove, and the chip on the device terminal group is favorably contacted with the chip on the chip mounting position electrically; compared with the prior art, the utility model simplifies the structure, reduces the difficulty of producing the die and is beneficial to saving the production cost.

Finally, it should be emphasized that the foregoing is merely a preferred embodiment of the present utility model, and is not intended to limit the utility model, but rather that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the utility model, and any modifications, equivalent substitutions, improvements, etc. are intended to be included within the scope of the present utility model.
