Wherein the positioning projections 452 are disposed on a side of the first row of terminals away from the first wall 40a, and/or the positioning projections 452 are disposed on a side of the fourth row of terminals adjacent to the first wall 40 a. Further, the positioning boss 452 is disposed on a side of the second row of terminals away from the first wall 40a, and/or the positioning boss 452 is disposed on a side of the third row of terminals adjacent to the first wall 40 a. In the Z-axis direction, the positioning boss is disposed between the first row L1 and the fourth row L4. Further, in the Z-axis direction, the positioning boss is disposed between the second line L2 and the third line L3. Specifically, the positioning bosses are provided on the + Z-axis direction side of the first row L1 and/or the second row L2, and the positioning portions are provided on the-Z-axis direction side of the third row L3 and/or the fourth row L4. With this structure, the chip 440, particularly the

terminals

441 and 449, can be positioned more accurately (particularly, the position in the Y-axis direction), and the situation that the

terminals

441 and 449 cannot be electrically connected to the printer-side terminal portion in a satisfactory manner can be prevented.

Alternatively, there may be only one positioning portion, or 2 or more positioning portions. As shown in fig. 5 and 6, the positioning portion in the present embodiment includes a first positioning boss 451 (hidden by the chip 440 in fig. 5), a second positioning boss 452; the first positioning projection 451 is provided on the fifth wall 40e, and the second positioning projection 452 is provided on the sixth wall 40 f. The first positioning projection 451 is a projection projecting in the-Y direction from the fifth wall 40e, and the second positioning projection 452 is a projection projecting in the + Y direction from the sixth wall 40 f. In the Z-axis direction, the first positioning boss 451 and the second positioning boss 452 are located at the same position and are arranged opposite to each other. The first positioning projection 451 is disposed in the-Y axis direction of the chip 440, and the second positioning projection 452 is disposed in the + Y axis direction of the chip 440. In the Z-axis direction, the first positioning projection 451 and the second positioning projection 452 are provided on the + Z-axis direction side of the first row L1 and the second row L2, and the positioning projection 451 and the second positioning projection 452 are provided on the-Z-axis direction side of the third row L3 and the fourth row L4. When the ink cartridge 40 is mounted on the mounting portion 30, the first positioning projections 451, the second positioning projections 452 engage with the corresponding projections of the

projections

351, 358 to prevent the ink cartridge 40 from being detached from the mounting portion 30. In this structure, the first positioning bosses 451 and the second positioning bosses 452 are disposed on the + Z-axis direction sides of the first row L1 and the second row L2, and on the-Z-axis direction sides of the third row L3 and the fourth row L4, so that the positioning of the first positioning bosses 451 and the second positioning bosses 452 on the chip 440, particularly the

terminals

441 and 449, is more accurate (particularly the position in the Y-axis direction), and the situation that the

terminals

441 and 449 cannot be electrically connected with the printer-side terminal portion well is prevented.

When the ink cartridge 40 is mounted on the mounting portion 30, the

positioning projections

451, 452 engage with the corresponding projections, preventing the ink cartridge 40 from being detached from the mounting portion 30. Thus, the ink cartridge has a simple structure, the mounting operation is easy, the ink cartridge 40 can be stably fixed in the mounting portion 30, and the chip 440 can be accurately electrically connected to the printer-side terminal portion. Specifically, taking the example of the ink cartridge 40 being mounted in the first mounting position 31 as an example, the order of mounting the ink cartridge 40 in the mounting portion 30 is: A. the ink cartridge 40 moves from the opening 40b of the mounting portion 30 to the bottom wall 30a in the-Z-axis direction. B. The first positioning projection 451 contacts the facing surface 311 of the mounting portion 30, and the second positioning projection 452 contacts the facing surface 312 of the mounting portion 30, and starts guiding the ink cartridge 40. C. The ink cartridge 40 moves down further, and the first positioning projections 451 and the second positioning projections 452 reach the positions of the first projections 351 and the second projections 352. D. The ink cartridge 40 continues to move in the-Z direction, the + Z side of the first positioning projection 451 abuts against the-Z side of the first protrusion 351, the + Z side of the second positioning projection 452 abuts against the-Z side of the second protrusion 352, and the ink cartridge 40 is mounted in place. E. At this time, the chip 440 is electrically connected to the printer side terminal portion 341, and the ink outlet 430 is matched with the ink supply portion 330.

Specifically, in the process of mounting the ink cartridge 40 to the mounting portion 30, the first positioning projection 451 is in contact with the facing surface 311 in the mounting portion 30, and the second positioning projection 452 is in contact with the facing surface 312 in the mounting portion 30, so that the ink cartridge 40 is guided. The opposing

surfaces

311 and 312 guide the ink cartridge 40 during the mounting of the ink cartridge 40, and prevent the ink cartridge 40 from shifting in the Y-axis direction. The situation that the ink cartridge 40 cannot be accurately mounted to the mounting portion 30 is effectively avoided. The process of mounting the ink cartridge 40 to the other mounting positions and the click position and effect are consistent and will not be described repeatedly.

When the printer needs to print, the ink in the ink chamber 420 will reach the print head along the ink outlet 430 and the ink supply portion 330, and the printing operation is completed.

The first positioning projection 451 engages with the first projection 351 and the second positioning projection 452 engages with the second projection 352, preventing the ink cartridge 40 from being displaced in the Y-axis direction. The first positioning projections 451 and the second positioning projections 452 are provided within the coverage area T of the chip 440 in the Z-axis direction. The first positioning boss 451 and the second positioning boss 452 are close to the chip 440. On the one hand, the ink box can be prevented from being separated from the mounting part of the printing equipment in the vertical direction, the structure is simple, the mounting operation is easy, the ink box can be stably fixed in the mounting part of the printing equipment, on the other hand, the ink box, particularly, the offset of a chip in the extending direction of the side wall where the chip is located can be prevented, and the condition that the offset error of the chip is large because the positioning lug boss is far away from the chip is avoided.

The first positioning boss 451 and the second positioning boss 452 are arranged on the + Z-axis direction side of the first line L1 and/or the second line L2 and on the-Z-axis direction side of the third line L3 and/or the fourth line L4, so that the positioning of the first positioning boss 451 and the second positioning boss 452 on the chip 440, particularly the terminal 441 and 449, is more accurate (particularly the position in the Y-axis direction), and the situation that the terminal 441 and 449 cannot be well electrically connected with the printer side terminal portion is prevented.

Alternatively, an elastic member may be added to the-X axis side of the ink cartridge. It is possible to make the ink cartridge have a certain movement space in the X-axis direction and to ensure that the ink cartridge 40 can be better fixed to the mounting portion 30. The elastic member may be a movable member having a certain distance from the body of the ink cartridge 40, a spring, a silicone rubber, a rubber, or other elastic material.

A hand-held portion may be added to an upper position of the first wall 40a or the third wall 40c to facilitate a user's hand force when removing the ink cartridge 40. The hand-held portion may be an anti-slip pattern 460 (as shown in fig. 5) for increasing the friction force, a movable member having a certain distance from the ink cartridge 40, or a protrusion fixed on the ink cartridge. The ink supply portion 330 may be an ink supply needle or an ink supply tube.

A movable handle is added on the-X axis side of the ink box, so that the ink box has a certain moving space in the X axis direction, and the ink box 40 can be better fixed on the mounting part 30.

The first positioning boss 451 and the second positioning boss 452 on the ink cartridge 40 may be integrally injection-molded protrusions with the cartridge body; alternatively, the first positioning projection 451 and the second positioning projection 452 may be disposed on a replaceable member, so that the same structure can be matched with a plurality of different ink cartridge structures; or a protrusion member separately attached to or engaged with the third wall 40 c; in addition, the elastic protrusion member may be mounted on the third wall 40c by means of adhesion, clipping, interference fit, etc., and the elastic protrusion member may be made of silicone, rubber, wood plug, etc.

Fig. 8 is an enlarged schematic view of another ink cartridge according to an embodiment of the present invention.

Referring to fig. 8, at least one positioning portion is provided on the fifth wall 40e or the sixth wall 40f, and specifically, the at least one positioning portion further includes: and the positioning plate is arranged on the fifth wall 40e or the sixth wall 40 f. Such as: the positioning plate 45a extends in the + X direction from the boundary position between the fifth wall 40e and the third wall 40c, and the positioning plate 45b extends in the + X direction from the boundary position between the sixth wall 40f and the third wall 40 c. The positioning bosses are located on the positioning plate within the range of the coverage area T of the chip 440 in the Z-axis direction.

The chip 440 includes a plurality of terminals arranged in a plurality of rows with the positioning bosses therebetween in the Z-axis direction.

In one possible implementation, the positioning part further includes: an elastic arm, one end of which is connected to the positioning plate and the other end of which is connected to the positioning boss, illustratively, as shown in fig. 8, one end of the elastic arm 45A is connected to the positioning plate 45A, the other end is connected to the positioning boss 451, one end of the elastic arm 45B is connected to the positioning plate 45B, and the other end is connected to the positioning boss 452.

The

elastic arms

45A and 45B have elasticity. In this embodiment, the

elastic arms

45A and 45B are elastic, and the first positioning projection 451 and the second positioning projection 452 are provided at the-Z-axis ends of the

elastic arms

45A and 45B. The first positioning projection 451 is a projection formed to project from the elastic arm 45A toward the-Y axis direction side, and the second positioning projection 452 is a projection formed to project from the elastic arm 45B toward the + Y axis direction side. The mounting of the ink cartridge 40 to the first mounting position is taken as an example: when the ink cartridge 40 is mounted on the mounting portion 30, the first positioning projection 451 engages with the first projection 351 and the second positioning projection 452 engages with the second projection 352, preventing the ink cartridge 40 from being displaced in the Y-axis direction and preventing the ink cartridge 40 from being detached from the mounting portion 30. The elastic arm 45A and the elastic arm 45B have elasticity at least in part, and the first positioning projection 451 and the second positioning projection 452 are provided at-Z-axis ends of the extension wall elastic arm 45A and the elastic arm 45B. This structure makes the ink cartridge 40 smoother and less likely to jam during the installation process. When the ink cartridge 40 is taken out from the mounting portion 30, it is more convenient and the user takes out the ink cartridge 40 with less force.

Of course, the shapes of the first positioning projection 451 and the second positioning projection 452 may be different, for example, the + Z-axis side of the first positioning projection 451 is a plane inclined downward, and the + Z-axis side of the second positioning projection 452 is a horizontal plane. When the ink cartridge 40 is mounted in the mounting portion 30, the inclined downward surface engages with the first projection 351 and the horizontal surface engages with the second projection 352. This structure makes the ink cartridge 40 more firmly engaged with the mounting portion 30. So, the shape of two location portions is different, can make the ink horn have certain floating space, can not produce the dead condition of card. Here, the shape of the positioning boss is not particularly limited.
