[0037] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0042] As described in the background art, when the chip of the ink cartridge is upgraded, the test head and the chip will not be aligned accurately, so that the contact pins of the test head cannot be electrically connected to the electrical contacts of the chip, resulting in low upgrade efficiency of the chip of the ink cartridge. The inventor has found through research that the reason for this problem is that when the chip of the ink cartridge is upgraded, there is no limit on the contact pin holder of the test head on the upgrade device. After the test head moves in the height direction of the ink cartridge, the test head and the chip will not be aligned accurately, and the contact pins of the test head will be separated from the electrical contacts on the chip, so that the contact pins of the test head cannot be electrically connected to the electrical contacts of the chip, resulting in low upgrade efficiency of the chip of the ink cartridge.

[0043] In order to solve the above problems, an embodiment of the utility model provides an ink cartridge, wherein a limiting portion is provided, and the limiting portion limits the contact pin holder of the test head in the height direction of the ink cartridge, so that the test head is stationary relative to the chip, and the test head and the chip are accurately aligned, or the moving range of the test head relative to the chip in the height direction of the ink cartridge is reduced, and the test head and the chip are accurately aligned, preventing the contact pins of the test head from detaching from the electrical contacts on the chip, and ensuring a stable electrical connection between the contact pins of the test head and the electrical contacts on the chip, thereby improving the upgrading efficiency of the chip of the ink cartridge.

[0044] It should be pointed out that when the limiting portion of the ink cartridge limits the contact pin holder of the test head in the height direction of the ink cartridge so that the test head has a moving range in the height direction of the ink cartridge relative to the chip, the moving range is reduced relative to the moving range of the test head when the ink cartridge is not provided with a limiting portion in the prior art.

[0045] The ink cartridge provided by the embodiment of the utility model is described in detail below in conjunction with specific embodiments.

[0046] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an ink cartridge that can be connected to a test head 100 on an upgrade device. The test head 100 is a rectangular structure. The test head 100 includes a stylus 200 and a stylus holder 300 . The stylus 200 is arranged on the stylus holder 300 .

[0047] like Figure 3 and Figure 4 As shown, the ink cartridge includes a chip mounting portion 10 (see Figure 7 As shown), the chip 20 and the limiting part, the chip mounting part 10 is used to accommodate the test head 100, and the chip mounting part 10 has a first side end face 101 and a second side end face 102; the chip 20 is mounted on the first side end face 101, and the chip 20 is provided with an electrical contact 201 facing the second side end face 102; the limiting part is arranged in the chip mounting part 10, and the limiting part is constructed to limit the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge so that the contact pin 200 of the test head 100 is electrically connected to the electrical contact 201.

[0048] Among them, Figure 1 The X-axis, Y-axis, and Z-axis are depicted as three spatial axes that are orthogonal to each other. The directions pointed by the arrows of the X-axis, Y-axis, and Z-axis represent the positive directions along the X-axis, Y-axis, and Z-axis, respectively. The positive directions along the X-axis, Y-axis, and Z-axis are respectively set as the +X-axis direction, the +Y-axis direction, and the +Z-axis direction. The directions of the X-axis, Y-axis, and Z-axis opposite to the directions pointed by the arrows are respectively the negative directions along the X-axis, Y-axis, and Z-axis. The negative directions along the X-axis, Y-axis, and Z-axis are respectively set as the -X-axis direction, the -Y-axis direction, and the -Z-axis direction. In the directions along the X-axis, Y-axis, and Z-axis, the directions regardless of positive or negative are respectively referred to as the X-axis direction, the Y-axis direction, and the Z-axis direction.

[0049] In the normal use state of the ink cartridge, the length direction of the ink cartridge is defined as the X-axis direction, the width direction of the ink cartridge is defined as the Y-axis direction, and the height direction of the ink cartridge is defined as the Z-axis direction. The normal use state of the ink cartridge refers to the state of the ink cartridge when the printer is working normally, that is, the state of the ink cartridge when the ink cartridge is installed in the printer body and the printer is working normally.

[0050] The coordinate system of the test head 100 is the same as the coordinate system of the ink cartridge. The length direction of the test head 100 is the X-axis direction, the height direction of the test head 100 is the Z-axis direction, and the width direction of the test head 100 is the Y-axis direction. A plurality of styluses 200 are provided on one side of the stylus holder 300 in the -X-axis direction.

[0051] The first side end surface 101 and the second side end surface 102 are disposed opposite to each other in the width direction of the ink cartridge.

[0052] The chip mounting portion 10 has an upper end surface 103 and a lower end surface 104 that are oppositely disposed in the height direction of the ink cartridge. The upper end surface 103 and the lower end surface 104 are connected between the first side end surface 101 and the second side end surface 102 , respectively.

[0053] See also Figure 5As shown, the chip mounting portion 10 further has a bottom end surface 105 in the length direction of the ink cartridge, and the bottom end surface 105 is connected to the first side end surface 101, the second side end surface 102, the upper side end surface 103 and the lower side end surface 104 respectively.

[0054] The chip 20 is located between the upper end surface 103 and the lower end surface 104 in the height direction of the ink cartridge.

[0055] A plurality of electrical contacts 201 are disposed on one side of the chip 20 in the +Y axis direction, and each electrical contact 201 corresponds to a contact pin 200. When the contact pins 200 of the test head 100 are electrically connected to the electrical contacts 201 of the chip 20, the chip 20 can be upgraded.

[0056] When the contact pin holder 300 of the test head 100 is inserted into the chip mounting portion 10 where the chip 20 of the ink cartridge is located along the length direction of the test head 100, the limiting portion can limit the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge, so that the test head 100 is stationary relative to the chip 20, and the multiple contact pins 200 of the test head 100 are electrically connected to the multiple electrical contacts 201 of the chip 20 in a one-to-one correspondence, and the test head 100 is accurately aligned with the chip 20, so that the contact pins 200 of the test head 100 are stably electrically connected to the electrical contacts 201 on the chip 20. In other embodiments, the limiting portion may also limit the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge, so that the moving range of the test head 100 relative to the chip 20 in the height direction of the ink cartridge is reduced, and the multiple contact pins 200 of the test head 100 are electrically connected to the multiple electrical contacts 201 of the chip 20 in a one-to-one manner. It can be understood that the limiting portion limits the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge, and after the test head 100 moves in the height direction of the ink cartridge relative to the chip 20, the multiple contact pins 200 of the test head 100 are still electrically connected to the multiple electrical contacts 201 of the chip 20 in a one-to-one manner, and the test head 100 is accurately aligned with the chip 20, so that the contact pins 200 of the test head 100 are stably electrically connected to the electrical contacts 201 on the chip 20.

[0057] It should be noted that the limiting portion can also limit the test head 100 in the height direction of the ink cartridge, so that the test head 100 is stationary relative to the chip 20, or the moving range of the test head 100 relative to the chip 20 in the height direction of the ink cartridge is reduced, so that the contact pins 200 of the test head 100 are stably electrically connected to the electrical contacts 201 on the chip 20.

[0058] The ink cartridge provided by the embodiment of the utility model, when the chip 20 of the ink cartridge is upgraded, the test head 100 on the upgraded device is inserted into the chip mounting portion 10, and a limiting portion is provided in the chip mounting portion 10. The limiting portion limits the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge, so that the test head 100 and the chip 20 can be accurately aligned, and the contact pins 200 of the test head 100 can be prevented from being separated from the electrical contacts 201 on the chip, so that the contact pins 200 of the test head 100 are stably electrically connected with the electrical contacts 201 on the chip 20, thereby improving the upgrading efficiency of the chip 20 of the ink cartridge.

[0059] In a possible implementation, Figure 1 As shown, the limiting portion includes two limiting members 30 , which are located on both sides of the chip 20 in the height direction of the ink cartridge, and the distance between the two limiting members 30 in the height direction of the ink cartridge is greater than or equal to the height of the contact pin bracket 300 .

[0060] The height of the stylus support 300 is the height in the Z-axis direction.

[0061] The limiting portion may be at least partially connected to the first side end surface 101, and the two limiting members 30 may be limiting ribs extending from the first side end surface 101. The two limiting ribs may be connected to the first side end surface 101 at one end and connected to the second side end surface 102 at the other end; the two limiting ribs may also be connected to the first side end surface 101 at one end and suspended at the other end; the two limiting ribs may also be the parts overlapping the upper side end surface 103 and the lower side end surface 104 that intersect the first side end surface 101 and the second side end surface 102 of the chip mounting portion, that is, one of the two limiting ribs is connected to the first side end surface 101, the second side end surface 102 and the upper side end surface 103, respectively, and the other limiting rib is connected to the first side end surface 101, the second side end surface 102 and the lower side end surface 104, respectively. In other embodiments, the limiting portion may also be at least partially connected to the second side end surface 102, that is, the limiting portion may be a limiting rib extending from the second side end surface 102, that is, one end may be connected to the second side end surface 102 and the other end may be suspended.

[0062] Exemplarily, two stoppers 30 are protrudingly arranged on the first side end surface 101, and the stoppers 30 are stopper ribs, which are perpendicular to the first side end surface 101. There is a gap between the two stoppers 30 and the second side end surface 102 in the width direction of the ink cartridge. It can be understood that the two stoppers 30 do not contact the second side end surface 102; in the width direction of the ink cartridge, the stopper 30 close to the upper side of the chip mounting portion 10 of the two stoppers 30 has a gap with the upper side of the chip mounting portion 10, and the stopper 30 close to the lower side of the chip mounting portion 10 of the two stoppers 30 has a gap with the lower side of the chip mounting portion 10, that is, the two stoppers 30 do not contact the upper side end surface 103 and the lower side end surface 104, so that the two stoppers 30 can be connected to the first side end surface 101 at one end and suspended at the other end.

[0063] In some other embodiments, the two limit members 30 can also protrude from the bottom end surface 105, that is, extend from the bottom end surface 105 along the +X axis direction, and the extension distance can be as large as the opening of the chip mounting portion 10, and at least partially extend to both sides of the chip 20 in the height direction of the ink cartridge, and the distance between the two limit members 30 in the height direction of the ink cartridge is greater than or equal to the height of the contact pin holder 300.

[0064] Among them, in the width direction of the ink cartridge, the limiting member 30 close to the upper side of the chip mounting portion 10 of the two limiting members 30 can be connected to at least one of the first side end face 101, the second side end face 102, and the upper side end face 103, or can be connected to none of them.

[0065] In the width direction of the ink cartridge, the limiting member 30 close to the lower side of the chip mounting portion 10 of the two limiting members 30 may be connected to at least one of the first side end surface 101 , the second side end surface 102 , and the lower side end surface 104 , or may not be connected to any of them.

[0066] In some other embodiments, the two limiting members 30 may also be respectively protruded from the upper end face 103 and the lower end face 104, and the two limiting members 30 limit the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge to achieve stable electrical connection between the contact pin 200 of the test head 100 and the electrical contact 201 on the chip 20.

[0067] In some other embodiments, only one stopper 30 may be provided in the chip mounting portion 10. It is sufficient to ensure that the contact pins 200 of the test head 100 are stably electrically connected to the electrical contacts 201 on the chip 20. Preferably, the stopper includes two parts, one part is a stopper 30, and the other is an upper end face 103 or a lower end face 104, that is, the stopper limits the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge through a stopper 30 and the upper end face 103, or the stopper limits the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge through a stopper 30 and the lower end face 104, so that the test head 100 is accurately aligned with the chip 20, and the contact pins 200 of the test head 100 are prevented from being separated from the electrical contacts 201 on the chip 20.

[0068] Furthermore, if Figure 6 and Figure 7 As shown, when the contact pin holder 300 of the test head 100 is inserted into the chip mounting portion 10 where the chip 20 of the ink cartridge is located along the length direction of the test head 100, and the distance between the two limiting members 30 in the height direction of the ink cartridge is equal to the height of the contact pin holder 300, the contact pin holder 300 abuts against the two limiting members 30 respectively, so that the two limiting members 30 limit the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge, thereby making the test head 100 stationary relative to the chip 20, and the multiple contact pins 200 of the test head 100 are electrically connected to the multiple electrical contacts 201 of the chip 20 in a one-to-one correspondence, and the test head 100 is accurately aligned with the chip 20, so that the contact pins 200 of the test head 100 are stably electrically connected to the electrical contacts 201 on the chip 20.

[0069] When the contact pin holder 300 of the test head 100 is inserted into the chip mounting portion 10 where the chip 20 of the ink cartridge is located along the length direction of the test head 100, and the distance between the two limiting members 30 in the height direction of the ink cartridge is greater than the height of the contact pin holder 300, the contact pin holder 300 of the test head 100 has a moving range in the height direction of the ink cartridge relative to the chip 20, and the contact pin holder 300 is restricted to move within the moving range, so that the two limiting members 30 limit the contact pin holder 300 of the test head 100 in the height direction of the ink cartridge, and then after the contact pin holder 300 moves, the multiple contact pins 200 of the test head 100 can still be electrically connected to the multiple electrical contacts 201 of the chip 20 one by one, and the test head 100 is accurately aligned with the chip 20, so that the contact pins 200 of the test head 100 are stably electrically connected to the electrical contacts 201 on the chip 20.

[0070] The maximum distance that the stylus holder 300 can move within the moving range in the height direction of the ink cartridge can be equal to the width of the electrical contact 201 in the height direction of the ink cartridge, or can be less than the width of the electrical contact 201 in the height direction of the ink cartridge.

[0071] In a possible implementation, in the height direction of the ink cartridge, the distances between the two limit members 30 and the center line of the chip 20 are equal. It can be understood that the two limit members 30 are symmetrically arranged relative to the center line of the chip 20 in the height direction of the ink cartridge.

[0072] Among them, Figure 6 and Figure 7 As shown, when the contact pin holder 300 of the test head 100 is inserted into the chip mounting portion 10 where the chip 20 of the ink cartridge is located along the length direction of the test head 100, when the distance between the two limiting members 30 in the height direction of the ink cartridge is equal to the height of the contact pin holder 300, the distance between the two limiting members 30 and the center line of the chip 20 in the height direction of the ink cartridge is equal, the contact pin holder 300 is respectively abutted against the two limiting members 30, and each contact pin 200 of the test head 100 contacts the center of the electrical contact 201 corresponding to the chip 20.

[0073] In a possible implementation, Figure 3 and Figure 4 As shown, the ink cartridge further comprises a shell 1 , which has a containing cavity, and the containing cavity contains ink. An ink outlet 40 is arranged on the shell 1 , and the ink outlet 40 is used to discharge the ink in the shell 1 .

[0074] The housing 1 has a front end surface 1 a on one side in the +X axis direction, and the ink outlet 40 is disposed on the front end surface 1 a .

[0075] like Figure 6 and Figure 7 As shown, the chip mounting portion 10 is a groove arranged on the front end surface 1 a of the housing 1 , and the groove and the ink outlet 40 are located on the same side of the housing 1 , that is, the groove and the ink outlet 40 are located on the front end surface 1 a of the housing 1 .

[0076] The chip mounting portion 10 is located above the ink outlet 40 , that is, the chip mounting portion 10 is located on one side of the ink outlet 40 in the +Z axis direction.

[0077] The first side end face 101 is parallel to the second side end face 102 , and both are perpendicular to the end face where the ink outlet 40 is located on the housing 1 , that is, both are perpendicular to the front end face 1 a .

[0078] The upper end surface 103 and the lower end surface 104 are parallel, and both are perpendicular to the end surface of the ink outlet 40 on the housing 1 , that is, both are perpendicular to the front end surface 1 a .

[0079] The first side end surface 101 , the second side end surface 102 , the upper side end surface 103 and the lower side end surface 104 are all perpendicular to the bottom end surface 105 , that is, the bottom end surface 105 is parallel to the front end surface 1 a .

[0080] It should be noted that an outer packaging box may be provided outside the ink cartridge, and an opening is provided on the outer packaging box at a position corresponding to the chip mounting portion 10. When upgrading the chip 20 on the ink cartridge, the test head 100 on the upgrading device may be directly passed through the opening of the outer packaging box and inserted into the chip mounting portion 10 where the chip 20 of the ink cartridge is located along the length direction of the test head 100.
