Description

Technical Field

[0001] This invention relates to the field of printing consumables technology, and more particularly to a chip and printing consumables. Background Technology

[0002] With the continuous advancement of science and technology, the printing equipment industry has developed rapidly, and the application of printing consumables in printing equipment is becoming increasingly widespread. Ink cartridges, toner cartridges, ribbons, and other printing consumables have become easily consumable parts of printing equipment. Printing consumables are equipped with chips that store information such as manufacturer information, remaining quantity information, category information, and color information. Therefore, the chips play a decisive role in the normal operation of printing equipment.

[0003] In existing technologies, certain types of printing consumables require linear insertion into the mounting section of a printing device. Specifically, the printing consumable is linearly inserted into the corresponding mounting position within the mounting section. The chip of the printing consumable has multiple terminals densely arranged, and these terminals have different voltages. All terminals are arranged on the same plane of the chip. When the printing consumable is in the installed state, the terminals on the chip of the printing consumable contact the pins in the mounting section of the printing device, thus achieving electrical connection.

[0004] However, the terminals on the chip of the printing consumable are relatively small in width, and the printing consumable may be offset in the width direction.

Detailed Implementation

[0083] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0084] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0085] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0086] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0087] In the above description, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0088] In the prior art, the width of the terminals on the chip of the printing consumable is small, and the printing consumable may be offset in the width direction of the printing consumable. The terminals of the chip and the contact pins of the mounting part are prone to abnormal connection, which makes the printing consumable unusable.

[0089] To address the aforementioned issues, this invention provides a chip and printing consumables. By introducing a side contact portion on the chip that contacts the side of the stylus, the offset of the printing consumables in the width direction can be effectively suppressed, ensuring the installation stability of the printing consumables and the connection reliability between the chip and the stylus of the mounting part of the printing device. As a result, the external terminals of the chip and the stylus of the mounting part are less prone to connection abnormalities, enabling the printing consumables to be used normally.

[0090] The chip and printing consumables provided in the embodiments of the present invention will be described in detail below with reference to specific examples.

[0091] Figure 1 This is a schematic diagram showing the printing consumable 10 to be installed on the mounting section 90. (See diagram below.) Figure 1 As shown, the mounting part 90 is a component of the printing device, used to carry multiple or one printing consumables 10. The printing consumables 10 are detachably installed in the mounting part 90 along the first direction P. When the printing consumables 10 are used up, new printing consumables need to be replaced.

[0092] The printing consumable 10 includes a chip 20, a handle 30, an ink outlet 40, and a housing 50. The mounting portion 90 has a stylus holder 91, an ink supply portion 92, an opening 95, and a bottom wall 90a. The printing consumable 10 is mounted into the mounting portion 90 through the opening 95 along a first direction P, where P can be a plumb line. The handle 30 secures the printing consumable 10 to the mounting portion 90, preventing it from detaching. The housing 50 stores ink, which flows through the ink outlet 40 to the ink supply portion 92, which then supplies ink to the print head, allowing the ink to be used for printing.

[0093] Figure 2 This is a schematic diagram of the stylus holder. Figure 1 and Figure 2 As shown, the stylus holder 91 includes a stylus 91a and a holder 91b, with the stylus 91a mounted on the holder 91b.

[0094] Figure 4 This is a schematic diagram of the structure of a chip using existing technology. (Example:) Figure 4 As shown, chip 20 has contact components that can make contact with the contact pins 91a of the contact pin holder 91 for the mutual transmission of electrical signals. See also Figure 1 A three-dimensional Cartesian coordinate system, namely the XYZ axis coordinate system, is established, and the three-dimensional Cartesian coordinate system of the printing consumable 10 is consistent with the three-dimensional Cartesian coordinate system of the mounting part 90. Taking the direction in which the printing consumable 10 is installed onto the mounting part 90 as the -Z axis direction (i.e., the first direction P), the direction in which the printing consumable 10 is detached from the mounting part 90 is the +Z axis direction. The opening 95 is located in the +Z axis direction, and the bottom wall 90a is located in the -Z axis direction. Under normal circumstances, the printing device is placed flat on an office desk or printing table, with the opening 95 of the mounting part 90 located above the direction of gravity and the bottom wall 90a located below the direction of gravity, thus facilitating the user's installation or removal of the printing consumable 10.

[0095] Furthermore, the mounting section 90 can hold one or more printing consumables 10 and has one or more mounting positions. In some examples, the mounting section 90 can hold four printing consumables 10, and the four printing consumables can store four different colors of ink, such as black, yellow, blue, and red.

[0096] In this embodiment, the mounting part 90 is an approximately cuboid or cube-shaped component with an opening 95. The inner sidewall and bottom wall 90a of the mounting part 90 constitute the mounting positions. The stylus holder 91 is mounted on the first sidewall 90c of the mounting part 90. The mounting positions are arranged sequentially in the Y-axis direction, with four mounting positions arranged sequentially in the Y-axis direction. The direction perpendicular to both the Y and Z axes is the X-axis direction, where the direction from the inside of the mounting part 90 towards the stylus holder 91 is the +X-axis direction. The +X-axis is perpendicular to the first sidewall 90c. When viewed along the +X-axis direction, in the YZ plane, when the +Z-axis is above, the +Y-axis direction is on the left.

[0097] Figure 2 This is a schematic diagram of the stylus holder. Figure 2 As shown, the contact pin holder 91 has multiple contact pins 91a mounted on the frame 91b, namely the first contact pin, the second contact pin, the third contact pin, the fourth contact pin, and the fifth contact pin. The contact pins 91a are thin, sheet-like metal plates that provide electrical conductivity and are not easily worn. The frame 91b has a first slit 981, a second slit 982, a third slit 983, a fourth slit 984, and a fifth slit 985. Specifically, the first slit 981, the second slit 982, the third slit 983, the fourth slit 984, and the fifth slit 985 correspond to the first, second, third, fourth, and fifth contact pins, respectively. Each of the first, second, third, fourth, and fifth slits is U-shaped, with a slit opening in the +Z axis direction. The first, second, third, fourth, and fifth contact pins are installed into the first, second, third, fourth, and fifth slits respectively through the slit openings in the -Z axis direction. Specifically, the first contact pin is installed into the first slit 981 through the slit opening in the -Z axis direction; the installation methods for the second, third, fourth, and fifth contact pins are the same and will not be repeated here.

[0098] One side of each stylus 91a of the stylus holder 91 is connected to the main circuit of the printing device through the circuit inside the mounting part 90, and the other side is connected to the chip 20.

[0099] All the styluses 91a in the stylus holder 91 have the same structure, such as Figure 3As shown. Taking the stylus 91a fixed in the first slit 981 as an example, the stylus 91a is divided into a first part 911a, a second part 911b, and a third part 911c. The first part 911a or the third part 911c is used to connect to the chip 20, the second part 911b is used to connect to the internal circuit of the printing device, and the third part 911c is connected to the first part 911a and the second part 911b. The third part 911c is located in the +Z axis direction of the stylus 91a, and the stylus 91a is fixed in the first slit 981 by the third part 911c or a part of the third part 911c (for example, the horizontal part 902h of the third part 911c). The first part 911a and the second part 911b are located at the end of the stylus 91a in the -Z axis direction, so that the first part 911a and the second part 911b can be elastically deformed and easily return to their original shape after deformation. The first part 911a of the stylus 91a is located in the -X-axis direction, and the second part 911b is located in the +X-axis direction. The first part 911a and the second part 911b protrude from the frame 91b, while the third part 911c does not protrude from the frame 91b.

[0100] Furthermore, the first part 911a and the second part 911b protrude from the frame 91b in the X-axis direction, with the frame 91b located between the first part 911a and the second part 911b. The first part 911a is closer to the mounting position than the second part 911b. The third part 911c is divided into a first vertical part 902k and a second vertical part 902j perpendicular to the X-axis direction, and a horizontal part 902h parallel to the X-axis direction; the horizontal part 902h connects the first vertical part 902k and the second vertical part 902j. The first vertical part 902k and the second vertical part 902j extend along the mounting direction (i.e., the Z-axis direction) parallel to the mounting direction of the printing consumable 10 to the mounting part. The first vertical portion 902k is closer to the mounting position than the second vertical portion 902j. The end of the first vertical portion 902k is connected to the first portion 911a, and the end of the second vertical portion 902j is connected to the second portion 911b. The horizontal portion 902h or the first vertical portion 902k and the second vertical portion 902j are fixed in the first slit 981 in the +Z axis direction.

[0101] The first part 911a is located at the end of the stylus 91a. The first part 911a of the stylus 91a contacts the terminal of the chip 20, forming a contact area; the second part 911b is connected to the circuitry within the printing device. The third part 911c connects the first part 911a and the second part 911b. The first part 911a is the ridge area, the first vertical part 902k is the vertical area, the second part 911b is another ridge area, and the second vertical part 902j is another vertical area. The stylus 91a in the first slit 981 to the fifth slit 985 have the same arrangement and structure as the stylus 91a in the first slit 981, and their detailed illustrations and descriptions will not be provided here.

[0102] See Figure 1 and Figure 4 The original printing consumable 10 uses a chip 20, which includes a base portion 21. The base portion 21 has five terminals on its outer surface 211, which is away from the housing 50. The functions of each terminal are roughly as follows:

[0103] The first terminal 231 is a data terminal, used for transmitting or receiving data signals, and also for detecting a short circuit between the first terminal 231 and at least one of the second terminal 232, the third terminal 233, or the fourth terminal 234.

[0104] The second terminal 232 is a clock terminal, used to receive clock signals.

[0105] The third terminal 233 is a power supply terminal. The third terminal 233 is used to receive a power supply potential different from the ground potential, and power is provided for the operation of the memory (not shown in the figure) through this terminal.

[0106] The fourth terminal 234 is a reset terminal, which is used to reset the data inside the chip.

[0107] The fifth terminal 235 is a grounding terminal, which is used to receive grounding potential.

[0108] Among them, the first terminal 231, the second terminal 232, the third terminal 233 and the fourth terminal 234 are located on the -Y side of the outer surface 211, the fifth terminal 235 is located on the +Y side of the outer surface 211, the contact portion of the second terminal 232, the third terminal 233 and the fifth terminal 235 (the shaded area on the corresponding terminal in the figure) is located on the first imaginary line L1 parallel to the Y axis, the contact portion of the first terminal 231 and the fourth terminal 234 is located on the second imaginary line L2 parallel to the Y axis, and the second imaginary line L2 is located on the +Z side of the first imaginary line L1.

[0109] The first terminal 231 to the fifth terminal 235 are all located on the outer surface 211, and the distance between the end faces of these five terminals and the outer surface 211 is equal. Therefore, the contact portions of the first terminal 231 to the fifth terminal 235 are in the same plane. In addition, the dimensions of these five terminals are also quite similar, and their lengths in the Z-axis direction are significantly greater than their lengths in the Y-axis direction. Even a small offset of the printing consumable 10 in the Y-direction may affect the electrical connection between the terminals and the printer, causing the printing consumable 10 to malfunction.

[0110] Example 1

[0111] like Figures 5 to 7 As shown, an embodiment of the present invention provides a chip 20, which is mounted on a printing consumable 10 and engaged with a stylus holder 91 of a printing device. The printing consumable 10 is mounted in the mounting portion 90 of the printing device along a first direction P. The stylus holder 91 includes a frame 91b and a plurality of styluses 91a disposed on the frame 91b. The first portion 911a of each stylus 91a has a tip 9111 and a side 9112. The chip 20 includes a base portion 21 and a contact component for contacting the styluses 91a. The base portion 21 is provided with an outer surface 211 near the stylus holder 91. The contact component includes at least one external terminal 22 disposed on the outer surface 211 that contacts the tip 9111 of the corresponding stylus 91a. The base portion 21 is also provided with a memory electrically connected to the external terminal 22.

[0112] The contact assembly also includes at least one side connection 24 electrically connected to the memory. The side connection 24 can contact the side surface 9112 of the corresponding stylus 91a in the second direction S. The contact portion of the side connection 24 with the corresponding stylus 91a is located on the side of the outer surface 211 away from the stylus holder 91.

[0113] In this embodiment, the second direction S is perpendicular to the first direction P and parallel to the outer surface 211. The second direction S can be the width direction of the printing consumable 10, or it can form an angle with the width direction of the printing consumable 10. In this embodiment, the second direction S is the width direction of the printing consumable 10.

[0114] like Figure 5 and Figure 6 As shown, the outer surface 211 is the largest outer surface on the base portion 21, and the outer surface 211 is parallel to the YZ surface. The contact assembly includes a data terminal, a clock terminal, a power terminal, a reset terminal, and a ground terminal. The contact portion between the data terminal and the corresponding pin 91a is the data contact portion, the contact portion between the clock terminal and the corresponding pin 91a is the clock contact portion, the contact portion between the power terminal and the corresponding pin 91a is the power contact portion, the contact portion between the reset terminal and the corresponding pin 91a is the reset contact portion, and the contact portion between the ground terminal and the corresponding pin 91a is the ground contact portion.

[0115] The contact portion between the side contact portion 24 and the corresponding contact pin 91a is at least one of a clock contact portion, a power contact portion, and a ground contact portion.

[0116] In some examples, the external surface 211 may have four external terminals 22, which are data terminals, clock terminals, power terminals, and reset terminals, respectively. Each of the four external terminals 22 has a first contact portion 221 (in the attached figure, the corresponding first contact portion is indicated by a shaded area filled with diagonal lines on the terminal). The four first contact portions 221 are data contact portions, clock contact portions, power contact portions, and reset contact portions, respectively. In the Y direction, the first contact portions 221 of the four external terminals 22 are spaced apart and do not overlap. The four external terminals 22 are arranged in two rows, namely a first row and a second row. Each row has two external terminals 22. The line connecting the first contact portions 221 of the two external terminals 22 in the first row is parallel to the line connecting the first contact portions 221 of the two external terminals 22 in the second row.

[0117] The memory is used to store information such as manufacturer information, ink volume information, ink cartridge type information, and ink color.

[0118] Each contact pin 91a corresponds to an external terminal 22 or a side connection 24.

[0119] This invention, by introducing a side connection portion 24 on the chip 20 that contacts the side surface 9112 of the pin 91a, can effectively suppress the offset of the printing consumable in the width direction of the printing consumable, ensuring the installation stability of the printing consumable 10 and the connection reliability between the chip 20 and the pin 91a of the mounting part 90 of the printing device. This reduces the likelihood of connection abnormalities between the external terminal 22 of the chip 20 and the pin 91a of the mounting part 90, allowing the printing consumable 10 to function normally. Furthermore, the introduction of the side connection portion 24 also allows for control of the size of the base portion 21, which is beneficial for the miniaturization design of the chip 20 and helps control chip costs.

[0120] Optionally, the projection of the contact portion of the side contact portion 24 and the corresponding contact pin 91a on the outer contact surface 211 is located at the edge of the projection outline of the base portion 21 on the outer contact surface 211.

[0121] The base portion 21 is a flat plate and has an inner surface 212 parallel to the outer surface 211. The inner surface 212 is disposed away from the stylus holder 91 relative to the outer surface 211.

[0122] The side connection portion 24 is located on the side of the base portion 21 at one end in the second direction S. The base portion 21 has a first side connection surface 213 at one end in the second direction S. The first side connection surface 213 is perpendicular to the outer connection surface 211. The side connection portion 24 includes a first side terminal disposed on the first side connection surface 213.

[0123] like Figure 5 and Figure 6 As shown, the side connection portion 24 further includes a side surface 241, a first transition surface 242, and a second transition surface 243. The side surface 241 may be flush with the first side connection surface 213. In other embodiments, the side surface 241 may not be flush with the first side connection surface 213, but may be located on the +Y side of the first side connection surface 213, and there may be a certain distance between the side surface 241 and the first side connection surface 213. The length of the side surface 241 in the X direction is less than the length of the first side connection surface 213 in the X direction. The first side terminal is located on the side surface 241, and the side surface 241 is parallel to the XZ plane.

[0124] The first transition surface 242 connects the side surface 241 and the outer surface 211, and the second transition surface 243 connects the side surface 241 and the inner surface 212. Both the first transition surface 242 and the second transition surface 243 can be curved surfaces or inclined surfaces. In this embodiment, both the first transition surface 242 and the second transition surface 243 are curved surfaces.

[0125] In the Z direction, the edge of the base portion 21 is provided with recessed portions 214 at both ends of the side connection portion 24. Both recessed portions 214 are provided on the base portion 21 as process grooves, which is an inherent structure of this type of chip. In addition, in this embodiment, the first side terminal is formed by completely covering the side surface 241 with copper.

[0126] Furthermore, the contact portion between the first side terminal and the corresponding contact pin 91a can be a contact surface, a contact line, or a contact point.

[0127] In this embodiment, the contact portion between the first side terminal and the corresponding contact pin 91a is the contact surface, and the projection of the contact surface onto the outer surface 211 is a projection line parallel to the first direction P. This configuration allows for surface-to-surface contact between the first side terminal and the corresponding contact pin 91a, resulting in better contact stability.

[0128] The length of the side surface 241 in the X direction can be less than the length of the first side terminal 213 in the X direction. The first side terminal can correspond to a smaller copper area, which also helps to control chip cost.

[0129] The first side terminal can be a grounding terminal, and the first side terminal has a second contact portion 244a, which is a grounding contact portion.

[0130] like Figure 5 As shown, the chip 20 has a first end A1 and a second end A2 in the width direction of the printing consumable, and the side connection part 24 is disposed at the second end A2.

[0131] Optionally, the chip 20 further includes a positioning portion, which includes a positioning notch 215 located at the edge of the base portion 21 and a positioning through hole 216 located on the base portion 21. The positioning portion is used to cooperate with the protruding structure on the printing consumable 10 that plays a positioning role, so as to facilitate the positioning and installation of the chip 20. In this embodiment, the positioning notch 215 is located on the +Z side edge of the base portion 21, and the positioning through hole 216 is located on the -Z side of the base portion 21.

[0132] It should be noted that the number of positioning notches 215 and positioning through holes 216 is not limited here. Specifically, only one positioning notch 215 and one positioning through hole 216 can be provided, or two or more positioning notches 215 and two or more positioning through holes 216 can be provided. Furthermore, the shape of the positioning notches 215 and positioning through holes 216 is also not limited; the positioning holes can be circular, square, or irregularly shaped. Similarly, the specific shape and number of the protruding structures are not subject to excessive restrictions here.

[0133] Optionally, see Figure 7 The side of the printing consumable 10 containing the chip 20 needs to have a limiting part 11b provided outside the first side terminal. The limiting part 11b has a guiding slope that guides the stylus 91a toward the first side terminal. In this way, as the printing consumable 10 moves along the first direction P, the stylus 91a gradually shifts toward the -Y direction and moves toward the first side terminal under the action of the above-mentioned guiding slope until it contacts the second contact part.

[0134] It should be noted that the limiting part 11b allows the side connection part 24 of the chip 20 to maintain contact with the corresponding contact pin 91a. The limiting part 11b abuts against the side of the contact pin 91a corresponding to the side connection part 24 away from the side connection part 24. That is to say, the contact pin 91a is disposed between the side connection part 24 and the limiting part 11b in the Y direction, and the contact pin 91a is in contact with both the side connection part 24 and the limiting part 11b.

[0135] When viewing the chip 20 from the front external surface 211, i.e., along the -X direction, since the side surface 241 is perpendicular to the external surface 211, the first side terminal cannot be observed from this viewpoint, i.e., the second contact portion does not exist in the main view of the chip 20 corresponding to this viewpoint.

[0136] Example 2

[0137] This embodiment is largely the same as Embodiment 1, except for the side connection part. Therefore, for ease of understanding, the structural features corresponding to Embodiment 1 in this embodiment use the same reference numerals as in Embodiment 1.

[0138] See Figure 8 , Figure 9 , Figure 10In this embodiment, the side connection portion includes a first transition surface 242 that intersects with the outer connection surface 211 and a second transition surface 243 that intersects with the inner surface 212. The first transition surface 242 and the second transition surface 243 intersect, and the intersection line of the first transition surface 242 and the second transition surface 243 is the side intersection line 245.

[0139] The side intersection line 245 may or may not be flush with the first side interface 213.

[0140] The first side terminal is formed by fully copper plating at the first transition surface 242, the second transition surface 243, and the side intersection line 245. In practice, only a small area of ​​copper plating is needed on the first transition surface 242 and the second transition surface 243 to meet the electrical connection requirements. The second contact portion 244a is located on the side intersection line 245. Because the deformation amplitude of the contact pin 91a corresponding to the side contact portion in the X direction differs from that of other contact pins in the installed state, the position of the second contact portion 244a in the Z direction differs from the position of the first contact portion 221 of the two external terminals 22 on the second row in the Z direction. Furthermore, the shape of the second contact portion 244a differs from the shape of the first contact portion 221 of the two external terminals 22 on the second row.

[0141] The projection of the second contact portion 244a along the +X direction may not lie on the line connecting the first contact portions 221 of the two external terminals 22 on the second row. The second contact portion 244a is indicated by a side intersection line 245 within the dashed box in the figure.

[0142] Compared to Embodiment 1, this embodiment can effectively suppress the overall offset of the printing consumable 10 in the +Y direction under the installation state, and is conducive to the miniaturization design of the chip 20 and the control of chip cost. In addition, since the outer surface 211 is further narrowed into a side intersection line 245, the copper area corresponding to the first side terminal can be further reduced, which is more conducive to controlling chip cost.

[0143] When viewing the chip 20 from the perspective of the external surface 211, i.e., along the -X direction, the second contact portion 244a cannot be observed from this perspective because the side intersection line 245 where the second contact portion 244a is located is not on the external surface 211 and is located outside the external surface 211. In other words, the second contact portion 244a does not exist in the main view of the chip 20 corresponding to this perspective.

[0144] In this embodiment, the contact portion between the first side terminal and the corresponding contact pin 91a is a contact line. The contact line can be perpendicular to the outer surface 211, or its projection on the outer surface 211 can be parallel to the first direction P.

[0145] The rest is the same as in Example 1.

[0146] Example 3

[0147] See Figures 11 to 13 The chip 20 provided in this embodiment includes a base portion 21 and a contact component for contacting a stylus 91a. The base portion 21 is provided with an outer surface 211 near the stylus holder 91. The contact component includes at least one external terminal 22 provided on the outer surface 211 that contacts the tip 9111 of the stylus holder 91 corresponding to the stylus 91a. The base portion 21 is also provided with a memory 23 that is electrically connected to the external terminal 22.

[0148] The contact assembly also includes at least one side connection that is electrically connected to the memory. The side connection can contact the side surface 9112 of the corresponding stylus 91a in the second direction S. The contact portion of the side connection and the corresponding stylus 91a is located on the side of the outer surface 211 away from the stylus holder 91.

[0149] Wherein, the second direction S is the width direction of the printing consumable 10, and the second direction S is the same as the Y direction.

[0150] The base portion 21 includes a first plate 21a and a second plate 21b stacked together. The first plate 21a is located on the +X side of the second plate 21b. The outer surface 211 is the outer surface of the first plate 21a facing away from the second plate 21b. The outer surface 211 is in the +X direction of the first plate 21a. The end face of the first plate 21a in the -X direction is the inner surface 212. Both the outer surface 211 and the inner surface 212 are parallel to the YZ plane. At least one external terminal 22 is provided on the outer surface 211 on the -Y side, which contacts the tip 9111 of the corresponding stylus 91a on the stylus holder 91. The external terminal 22 has a first contact portion 221.

[0151] like Figure 12 and Figure 13 As shown, the first plate 21a has a first notch 15 on the +Y side, and a memory 23 is provided on the inner surface 212. The memory 23 is electrically connected to the external terminal 22. In some examples, four external terminals 22 can be provided on the external surface 211. Each of the four external terminals 22 has a first contact portion 221 (the corresponding first contact portion 221 is marked by a shaded area filled with diagonal lines on the terminal in the figure). In the Y direction, the first contact portions 221 of the four external terminals 22 are spaced apart and do not overlap. The four external terminals 22 are arranged in two rows, namely the first row and the second row. Each of the first row and the second row has two external terminals 22. The line connecting the first contact portions 221 of the two external terminals 22 in the first row is parallel to the line connecting the first contact portions 221 of the two external terminals 22 in the second row.

[0152] like Figure 14As shown, the end face of the second plate 21b in the +X direction is a mating surface 217 that partially overlaps with the inner surface 212. The second plate 21b has an exposed portion at one end in the second direction S that does not overlap with the first plate 21a, and a side connection portion is located on the side surface of the exposed portion at one end in the second direction S. Specifically, the exposed portion is the area where the second plate 21b overlaps with the first notch 15. The +Y side of the exposed portion has a side surface 241 parallel to the Z-axis, and the side connection portion is disposed on the side surface 241. The side connection portion includes a first side terminal disposed on the side surface 241, and the first side terminal has a second contact portion 244a.

[0153] The first side terminal is used to contact the side surface 9112 of the contact pin 91a to achieve electrical connection between the contact pin 91a and the chip 20. The side surface 241 is parallel to the XZ plane, and the length of the side surface 241 in the X direction is less than the length of the second plate 21b in the X direction. The side surface 241 is connected to the mating surface 217 through the first transition surface 242, and the side surface 241 is connected to the -X direction end face of the second plate 21b through the second transition surface 243. In this embodiment, both the first transition surface 242 and the second transition surface 243 are arc surfaces. Therefore, the arrangement of the first side terminal and the surrounding structure on the second plate 21b in this embodiment is similar to that in Embodiment 1.

[0154] like Figure 13 As shown, the mating surface 217 has a connecting terminal 25 electrically connected to the first side terminal in the area overlapping with the inner surface 212. The inner surface 212 has an inner terminal (not shown in the figure) that contacts the connecting terminal 25. The inner terminal is electrically connected to the memory 23. In this way, the first side terminal can be connected to the memory 23 through the connection terminal 25 and the inner terminal.

[0155] In some embodiments, other terminals of the chip 20 can be configured as side terminals on the second plate 21b and made to contact the side 9112 of the corresponding contact pin 91a. In other embodiments, the first transition surface 242 and the second transition surface 243 can also be configured as flat bevels, which can also serve as a transition connection between the side surface 241 and the mating surface 217 and the -X direction end face of the second plate 21b.

[0156] When the printing consumable 10 is in the installed state, the contact pin 91a corresponding to the side connector 24 hardly deforms in the X direction. Therefore, its deformation amplitude in the X direction is significantly smaller than that of the contact pin 91a corresponding to the external terminal 22 in the X direction. The position of the second contact portion 244a in the Z direction is different from the position of the first contact portion 221 of the two external terminals 22 on the second row in the Z direction. Furthermore, the shape of the second contact portion 244a is different from the shape of the first contact portion 221 of the two external terminals 22 on the second row.

[0157] The projection of the second contact portion 244a along the +X direction may not be located on the line connecting the first contact portions 221 of the two external terminals 22 on the second row.

[0158] Since the first side terminal directly abuts against the side 9112 of the contact pin 91a, it can effectively suppress the overall offset of the printing consumable in the +Y direction during installation. Unlike the point-to-surface contact between the external terminal 22 and the corresponding contact pin 91a, the first side terminal and the contact pin 91a have a surface-to-surface contact, which has better contact stability. The length of the side surface 241 in the X direction can be less than the length of the second plate 21b in the X direction, and the first side terminal can correspond to a smaller copper area, which also helps to control chip cost.

[0159] When viewing the chip 20 from the external surface 211, i.e., from the -X direction, the second contact 244a cannot be observed from this viewpoint because the side surface 241 where the second contact 244a is located is perpendicular to the external surface 211. That is, the second contact 244a does not exist in the main view of the chip 20 corresponding to this viewpoint.

[0160] See also Figure 14 Alternatively, the first side terminal and surrounding structure on the second plate 21b can be configured with reference to Embodiment 2. Specifically, a first transition surface 242 and a second transition surface 243 are intersecting on the +Y side of the area where the second plate 21b overlaps with the first notch 15. The first transition surface 242 also intersects with the mating surface 217, and the second transition surface 243 also intersects with the -X end face of the second plate 21b. The intersection line of the first transition surface 242 and the second transition surface 243 is a side intersection line 245 extending in the Z direction. In specific implementation, copper can be completely coated on the side intersection line 245 and the first transition surface 242 and the second transition surface 243 as the first side terminal, and the second contact part 244a is located on the side intersection line 245. In this way, the first side terminal and the side of the stylus 91a are directly abutted in the installed state, which can effectively suppress the overall offset of the printing consumable in the +Y direction. The technical effects of this embodiment in other aspects are similar to those of Embodiment 2, and will not be elaborated here.

[0161] Example 4

[0162] This embodiment is largely the same as Embodiment 1, except that the chip 20 is installed in a different way. Specifically, the chip 20 in Embodiment 1 is parallel to the front surface 10a of the consumable body, while the chip 20 in Embodiment 4 is tilted relative to the front surface 10a of the consumable body.

[0163] like Figure 16 As shown, an embodiment of the present invention provides a printing consumable 10, including a consumable body and a chip 20; the chip 20 is mounted on the outer surface of the consumable body.

[0164] The consumable body has a front surface 10a on the third direction K, and the front surface 10a has a mounting base 11. The chip 20 is mounted on the mounting base 11, and the mounting base 11 makes the distance between the two ends of the chip 20 in the width direction of the printing consumable and the frame 91b of the stylus holder 91 of the printing device different.

[0165] Wherein, the third direction K is the length direction of the printing consumable 10, the width direction of the printing consumable 10 is the +D axis direction or the -D axis direction, the first direction P is the height direction of the printing consumable 10, the first direction P, the +D axis direction and the third direction K are perpendicular to each other, and the printing consumable 10 is installed on the mounting part 90 of the printing device along the first direction P.

[0166] The structure of chip 20 is the same as that of chip 20 in embodiment one. For example... Figure 15 As shown, the base portion 21 of the chip 20 has an outer surface 211, an inner surface 212, a left side surface 120c, a first side surface 213, a top side surface 120e, and a bottom side surface 120f. The outer surface 211 is positioned opposite the inner surface 212, and is located on the +X side of the inner surface 212. The left side surface 120c is positioned opposite the first side surface 213, and is located on the -Y axis side of the first side surface 213. The top side surface 120e and the bottom side surface 120f are positioned opposite each other, and the top side surface 120e is located on the +Z axis side of the bottom side surface 120f. The side contact portion 24 of the chip 20 is disposed on the first side surface 213.

[0167] It should be noted that the +X-axis, +Y-axis, and +Z-axis are perpendicular to each other; the +Z-axis is parallel to the +P-axis; the +Y-axis is not parallel to the +D-axis, meaning it intersects with the +D-axis, or in other words, there is an angle between them; and the +X-axis is not parallel to the +K-axis, meaning it intersects with the +K-axis, or in other words, there is an angle between them.

[0168] Four external terminals 22 may be provided on the external surface 211. Each of the four external terminals 22 has a first contact portion 221. The first contact portion 221 is the contact area between the stylus and the external terminal 22 when the printing consumable 10 is installed in the mounting part of the printing device.

[0169] like Figures 15 to 18As shown, the printing consumable 10 also has a left surface 10b and a right surface 10c in the width direction, with the left surface 10b and right surface 10c arranged opposite to each other. The mounting base 11 extends toward the +X axis and is inclined toward the left surface 10b or right surface 10c of the consumable body. Therefore, after the chip 20 is installed with the consumable body, along the +K axis direction, the left side surface 120c of the base portion 21 is located in front of the first side contact surface 213 of the base portion 21. When the chip 20 is installed on the mounting base 11, along the +Y axis direction, the side contact portion 24 is located between the left side surface 120c and the +X side edge of the first side contact surface 213. When viewed along the -K direction, the side contact portion 24 cannot be seen with the naked eye. The advantage of this design is that, since the mounting base 11 is tilted on the front surface 10a of the consumable body, and the chip 20 is mounted on the mounting base 11, the chip 20 will also be tilted on the front surface 10a of the consumable body. Therefore, the distances between the various external terminals 22 and side connectors 24 on the external surface 211 and the frame 91b of the pin holder 91 are different. Specifically, the distances between the various external terminals 22 and side connectors 24 and the front end 910 of the frame 91b are different.

[0170] When the stylus 91a of the mounting part comes into contact with the printing consumable 10, the deformation of each stylus 91a in the length direction is different, and the friction force that the printing consumable 10 needs to overcome in the width direction increases as the deformation of the stylus 91a increases, thereby limiting the offset of the printing consumable 10.

[0171] Since the side connection 24 is disposed on the first side connection surface 213 of the base portion 21, and is not on the same plane as the external terminal 22 disposed on the outer connection surface 211 of the base portion 21, and is shielded by the outer connection surface 211 in the -X direction, it is difficult to connect the side connection 24 and the external terminal 22 together when the base portion 21 is contaminated with liquid. Therefore, it can prevent the side connection 24 from short-circuiting with other terminals, reduce the risk of short circuit between the terminals of the chip 20, and improve the safety of chip use.

[0172] In addition, the mounting base 11 can prevent the side connector 24 from being exposed on the outside of the main body of the printing consumable 10, and prevent the side connector 24 from being scratched or damaged during the installation or use of the chip 20, thus providing a certain degree of protection for the side connector 24.

[0173] Optionally, the projection of the side contact portion 24 of the chip 20 and the corresponding contact pin 91a onto the third direction K at least partially falls on the outer surface 211 of the chip 20.

[0174] Among them, such as Figure 18 As shown, the mounting base 11 has an inclined surface 11a, and the chip 20 is mounted on the inclined surface 11a.

[0175] like Figures 15 to 18As shown, chip 20 has a first end A1 and a second end A2 in the width direction of the printing consumable. The first end A1 is located on the -Y axis side of chip 20, and the second end A2 is located on the +Y axis side of chip 20. The first end A1 and the second end A2 are connected to the front end 910 of the frame 91b (as shown). Figure 1 The distances are different (as shown), and the side connection part 24 is provided at the second end A2.

[0176] Specifically, the inclined surface 11a is inclined toward the left surface 10b relative to the front surface 10a in the third direction K, and the first end A1 of the chip 20 is farther away from the front surface 10a relative to the second end A2 in the third direction K; or, the inclined surface 11a is inclined toward the right surface 10c relative to the front surface 10a in the third direction K, and the first end A1 is closer to the front surface 10a relative to the second end A2 in the third direction K.

[0177] The inclined surface 11a is the surface in contact between the mounting base 11 and the chip 20.

[0178] Optionally, such as Figures 15 to 17 ,as well as Figure 19 As shown, the mounting base 11 also has a limiting part 11b, which is provided on one side of the chip 20 in the width direction of the printing consumable. The limiting part 11b is used to guide and maintain the contact between the side 9112 of the stylus 91a corresponding to the side connection part 24 and the side connection part 24 during the process of mounting the printing consumable 10 to the mounting part of the printing device along the first direction P.

[0179] The limiting part 11b is located on the +Y axis side of the chip 20, and has a guiding surface 111 and a limiting surface 112. The limiting surface 112 is located on the +Z axis side of the guiding surface 111. The guiding surface 111 extends toward the -Z axis direction and is inclined away from the chip 20. The limiting surface 112 extends toward the +X axis direction and is inclined away from the chip 20.

[0180] The side connection 24 is located on the -Y axis side of the limiting surface 112.

[0181] Optionally, such as Figure 16 As shown, the consumable body has a top surface 10d and a bottom surface 10e in the first direction P. The top surface 10d and the bottom surface 10e are disposed opposite to each other. The limiting surface 112 is parallel to the side surface of the side connector 24 on the chip 20. The projection of the side connector 24 in the width direction of the printing consumable is located within the projection range of the limiting surface 112 in the width direction of the printing consumable. The guiding surface 111 has a first guiding end and a second guiding end. The first guiding end is connected to the limiting surface 112. The second guiding end is located in front of the first guiding end in the first direction P. In the width direction of the printing consumable, the distance between the second guiding end and the side connector 24 is greater than the distance between the first guiding end and the side connector 24.

[0182] Among them, the side surface 213 on the chip 20 where the side part 24 is located is the first side surface 213.

[0183] like Figure 16 As shown, during the process of the printing consumable 10 entering the mounting section 90, the guide surface 111 of the limiting section 11b guides the stylus 91a into the space between the limiting surface 112 and the first side contact surface 213 of the chip 20. After the limiting surface 112 contacts the stylus 91a, the printing consumable 10 continues to be installed. The limiting surface 112 causes the first part 911a of the stylus 91a to shift in the -Y axis direction and fit against the side contact section 24, thereby making contact with the side contact section 24 and achieving electrical connection. Since the side contact section 24 is located on the +Y axis side of the chip 20 in the installed state, it can prevent the chip 20 from shifting in the +Y axis direction, and plays a certain limiting role for the chip 20, which is beneficial to improving the stability of the electrical connection between the chip 20 and the stylus holder 91.

[0184] It should be noted that the printing consumable 10 can be configured with a shielding component, which is disposed on the limiting portion 11b. The shielding component covers the side connection portion 24, the guide surface 111, and the limiting surface 112. The shielding component has a cutout, through which the stylus 91a can pass and enter between the limiting surface 112 and the first side connection surface 213 of the chip 20 along the guide surface 111. The shielding component can isolate the side connection portion from other terminals, preventing short circuits between the side connection portion and other terminals, reducing the risk of short circuits due to electrical connections between chip terminals, and improving the safety of chip use. The structure of the shielding component in this embodiment can refer to the structure of the shielding component in Embodiment 8.

[0185] When the printing consumable 10 and the mounting part 90 are installed, along the +Y axis direction, the side connection part 24 is located between the first side connection surface 213 of the base part 21 and the limiting part 11b, and is in contact with the side connection part 24.

[0186] The side connection portion 24 includes a first side terminal disposed on the first side connection surface 213. The first side terminal may be disposed in a portion of the first side connection surface 213 closer to the inner surface 212. Alternatively, a portion of the base portion 21 near the first side connection surface 213 close to the outer surface 211 and the inner surface 212 is cut away along a cutting direction having components of the -Y axis and +X axis, and a cutting direction having components of the -Y axis and -X axis, respectively, forming a chamfered surface 120d1 parallel to the first side connection surface 213. The first side terminal is disposed on the chamfered surface 120d1, and the dimension of the chamfered surface 120d1 in the X-axis direction is smaller than the dimension of the first side connection surface 213 in the X-axis direction.

[0187] It should be noted that the shapes of the external terminal 22 and the first-side terminal are not limited. For example, the external terminal 22 and the first-side terminal can be rectangular, circular, or irregular in shape. They can be set to the same shape or to different shapes.

[0188] In other possible implementations, in addition to the first side terminal, other terminals may also be disposed on the left side surface 120c, the first side contact surface 213, or the inner surface 212 of the base portion 21, and contact their respective corresponding contact pins to achieve electrical connection. For example, taking an external terminal 22 on the external contact surface 211 as an example, the external terminal 22 may be disposed on the left side surface 120c of the base portion 21 and configured to contact the +Y side of the contact pin 91a in the chip 20 mounting state, thereby achieving electrical connection. Accordingly, in the +Y direction, the first side contact surface 213 of the base portion 21 is located on the front side of the left side surface 120c, and the limiting part 11b is located on the -Y side of the base portion 21.

[0189] Example 5

[0190] This embodiment is largely the same as Embodiment 4, except that in Embodiment 5, the side connection portion 24 of the chip 20 is disposed on the inner surface 212 of the base portion.

[0191] See Figure 20 and Figure 21 As shown, the projection of the contact portion of the side contact portion 24 and the corresponding stylus 91a on the outer contact surface 211 is located at the edge of the projection outline of the base portion 21 on the outer contact surface 211.

[0192] The base portion 21 is a flat plate with an inner surface 212 parallel to the outer surface. The inner surface 212 is positioned away from the stylus holder 91 relative to the outer surface 211.

[0193] The base portion 21 has a right side surface 120d in the second direction, and the side connection portion 24 is provided on the inner surface 212 of the base portion 21 near the edge of the right side surface 120d, and the +Y axis side surface of the side connection portion 24 is flush with the right side surface 120d of the base portion 21.

[0194] Optionally, such as Figure 21 As shown, the side contact portion 24 is a first conductive element disposed on the inner surface 212 at one end in the second direction. The contact portion of the side contact portion 24 and the corresponding stylus 91a are located on the side surface of the first conductive element at one end in the second direction. The projection of the contact portion of the first conductive element and the corresponding stylus 91a on the outer contact surface 211 coincides with the side edge line of the flat plate at one end in the second direction.

[0195] The second direction is the same as the Y direction. The first conductive element is a flat conductive element.

[0196] When the chip 20 is in the installed state, the side 9112 of the contact pin 91a abuts against the right side 120d of the base portion 21 and contacts the side connection portion 24, thereby achieving electrical connection. The advantage of this design is that, compared to setting it on the smaller right side 120d, setting the side connection portion 24 on the larger inner surface 212 of the base portion 21 makes operation more convenient and simpler, and reduces process requirements.

[0197] Similarly, when viewing the chip 20 in its installed state from the -X axis direction, the side connection portion 24 on the inner surface 212 cannot be seen with the naked eye. Since the side connection portion 24 and the external terminal 22 are not on the same plane, when liquid accidentally gets on the outer surface 211 of the base portion 21, it is difficult for the liquid to flow to the side connection portion 24 and connect it to other terminals, thus preventing a short circuit. This helps to improve the safety of the chip. At the same time, in the installed state, the side connection portion 24 also acts as a limiter for the chip 20, preventing the chip 20 from shifting in position in the +Y axis direction.

[0198] It should be noted that, in addition to the side connection portion 24, the external terminal 22 can also be disposed on the inner surface 212 in the form of a conductive element and electrically connected to the corresponding contact pin. For example, taking an external terminal 22 on the external connection surface 211 as an example, the external terminal 22 can be disposed on the inner surface 212 of the base portion 21 near the edge of the left side surface 120c, and the contact portion of the external terminal 22 on the inner surface 212 with the corresponding contact pin 91a is on the same plane as the left side surface 120c of the base portion 21. When the chip 20 is in the installed state, the external terminal 22 on the inner surface 212 is in contact with the +Y axis side of the side surface 9112 of the contact pin 91a on the +Y axis of the corresponding side surface 9112 of the contact pin 91a, thereby realizing electrical connection.

[0199] The rest is the same as in Example 4.

[0200] Example 6

[0201] This embodiment is largely the same as Embodiment 5, except that the position of the side connection portion 24 of the chip 20 on the inner surface 212 of the base portion 21 is different.

[0202] like Figure 22 and Figure 23 As shown, the projection of the contact portion of the side contact portion 24 and the corresponding stylus 91a on the outer contact surface 211 is located at the edge of the projection outline of the base portion 21 on the outer contact surface 211.

[0203] The base portion 21 is a flat plate and has an inner surface 212 parallel to the outer surface. The inner surface 212 is disposed away from the stylus holder 91 relative to the outer surface 211.

[0204] The base portion 21 is provided with a first notch 15 that penetrates the flat plate. The first notch 15 is located at one end of the flat plate in the second direction S. The side connection portion 24 is a second conductive member provided on the inner surface 212. The contact portion of the side connection portion 24 and the corresponding stylus 91a are located on the side of the second conductive member at one end in the second direction S. The projection of the contact portion of the second conductive member and the corresponding stylus 91a on the outer surface 211 coincides with the side edge line of the first notch 15 at one end in the second direction S.

[0205] When the chip 20 is in the installed state, the side 9112 of the contact pin 91a fits against the side of the first notch 15 and contacts the side connector 24, thereby achieving electrical connection. The advantage of this design is that, compared to setting it on the smaller right side surface 120d, setting the side connector 24 on the larger inner surface 212 of the base portion 21 makes operation more convenient and simpler, and reduces process requirements.

[0206] Optionally, such as Figure 23 As shown, the base portion 21 is provided with two fixing holes 219. The second conductive component includes a conductive body and two connecting arms. The two connecting arms are respectively connected to the two ends of the conductive body. The two connecting arms of the second conductive component are fixed in the two fixing holes 219 of the base portion 21.

[0207] The inner wall of the fixing hole 219 is coated with copper, and the connecting arm of the second conductive component is welded to the inner wall of the fixing hole 219.

[0208] It should be noted that the chip 20 can be configured with a shielding component, which is connected to the outer surface 211. The shielding component covers the first notch 15 and the side connection portion 24. The shielding component has a cutout, through which the contact pin 91a can pass and contact the side connection portion 24. The structure of the shielding component in this embodiment can refer to the structure of the shielding component in Embodiment 8.

[0209] Example 7

[0210] See Figures 24 to 27 As shown, the chip 20 provided in this embodiment includes a base portion 21 and a contact component for contacting a stylus 91a. The base portion 21 is provided with an outer surface 211 near the stylus holder 91. The contact component includes at least one external terminal 22 provided on the outer surface 211 that contacts the tip 9111 of the stylus holder 91 corresponding to the stylus 91a. The base portion 21 is also provided with a memory (not shown in the figure) that is electrically connected to the external terminal 22.

[0211] The contact assembly also includes at least one side connection that is electrically connected to the memory. The side connection can contact the side surface 9112 of the corresponding stylus 91a in the second direction S. The contact portion of the side connection and the corresponding stylus 91a is located on the side of the outer surface 211 away from the stylus holder 91.

[0212] The second direction is the width direction of the printing consumable 10, and the second direction is the same as the Y direction.

[0213] The base portion 21 of the chip 20 has an outer surface 211, an inner surface, a left side surface 120c, a right side surface 120d, a top side surface 120e, and a bottom side surface 120f. The outer surface 211 is positioned opposite the inner surface 212, and is located on the +X side of the inner surface. The left side surface 120c is positioned opposite the right side surface 120d, and is located on the -Y axis side of the right side surface 120d. The top side surface 120e and the bottom side surface 120f are positioned opposite each other, and the top side surface 120e is located on the +Z axis side of the bottom side surface 120f.

[0214] The memory can be disposed on any one or several surfaces of the base portion 21, preferably on the inner surface. The specific shape and structure of the chip 20 are not limited; those skilled in the art can configure it according to specific design requirements. For example, the chip 20 can be configured as a rectangular structure, a chamfered rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, or a parallelogram structure. Furthermore, the location of the memory is not limited. For example, the memory can be disposed on the side of the chip 20 near the rear end in the first direction P, or on the side of the chip 20 near the front end in the first direction P, or in the middle of the chip 20. Those skilled in the art can configure it according to specific design requirements, which will not be elaborated further here.

[0215] In some examples, the external surface 211 may be provided with four external terminals 22, which are respectively a data terminal, a power terminal, a reset terminal, and a ground terminal. Each of the four external terminals 22 has a first contact portion 221 (in the figure, the corresponding first contact portion is marked by a shaded area filled with diagonal lines on the terminal). In the Y direction, the first contact portions 221 of the four external terminals 22 are spaced apart and do not overlap. The four external terminals 22 are arranged in two rows, namely a first row and a second row. Each row has two external terminals 22. The line connecting the first contact portions 221 of the two external terminals 22 in the first row is parallel to the line connecting the first contact portions 221 of the two external terminals 22 in the second row.

[0216] This embodiment of the invention, by introducing a side connection portion 24 on the chip 20 that contacts the side surface 9112 of the stylus 91a, can effectively suppress the offset of the printing consumable in the second direction, ensuring the installation stability of the printing consumable 10 and the connection reliability between the chip 20 and the stylus 91a of the mounting portion 90 of the printing device. This reduces the likelihood of connection abnormalities between the external terminal 22 of the chip 20 and the stylus 91a of the mounting portion 90, allowing the printing consumable 10 to function normally. Furthermore, the introduction of the side connection portion 24 also allows for control of the size of the base portion 21, which is beneficial for the miniaturization design of the chip 20 and helps control chip costs.

[0217] Optionally, the projection of the contact portion of the side contact portion 24 and the corresponding contact pin 91a on the outer contact surface 211 is located at the edge of the projection outline of the base portion 21 on the outer contact surface 211.

[0218] The base portion 21 is a flat plate. The side connection portion 24 is located on the side of the flat plate at one end in the second direction S.

[0219] Furthermore, such as Figure 24 As shown, the base portion 21 is provided with a first notch portion 15 that penetrates the base portion 21. The first notch portion 15 is located at one end of the base portion 21 in the second direction, and the side connection portion 24 is located on the side of the first notch portion 15 at one end in the second direction.

[0220] The first notch 15 can be formed by recessing from the left side 120c to the right side 120d, or by recessing from the right side 120d to the left side 120c. In other ways, the first notch 15 can be configured as a through hole that penetrates the outer surface 211 and the inner surface, or as a blind hole that does not penetrate the inner surface.

[0221] The number and shape of the first notch 15 are not limited. Specifically, the base portion 21 may have only one first notch, or it may have two or more first notches, and each first notch may be rectangular, semi-circular, or other shapes.

[0222] like Figure 24 and Figure 25 As shown, the first notch 15 has a second side contact surface 151 at one end in the second direction. The second side contact surface 151 is perpendicular to the outer contact surface 211. The side contact portion 24 is a second side terminal provided on the second side contact surface 151. The contact portion between the second side terminal and the corresponding contact pin 91a is the contact surface.

[0223] The second side terminal can be a clock terminal, and the second side terminal has a second contact portion 244a, which is disposed on the second side contact surface 151.

[0224] like Figure 24As shown, the chip 20 has a first end A1 and a second end A2 in the width direction of the printing consumable, and the side connection part 24 is disposed at the first end A1.

[0225] like Figure 26 , Figure 27 As shown, when the chip 20 is in the mounting state, the second contact portion 244a of the second side terminal contacts the +Y axis sidewall of the stylus 91a, achieving electrical connection. Compared to the tip 9111 of the stylus 91a, the side surface 9112 has a larger area. Therefore, when the chip 20 is in the mounting state, compared to the prior art, the contact area between the second side terminal and the stylus 91a in this embodiment is larger, or the possible contact area between the two is larger. This is beneficial to improving the likelihood of smooth contact between the terminal of the chip 20 and the stylus 91a of the mounting portion 90, achieving a stable electrical connection, and is beneficial to the stable operation of the printing equipment.

[0226] Furthermore, in this embodiment, since the +Y axis side of the stylus 91a contacts the second side contact surface 151 of the first notch portion 15 on the base portion 21, the stylus 91a can prevent the chip 20 from shifting position along the -Y axis direction, which helps to improve the stability of chip 20 installation and use.

[0227] Optional, such as Figure 25 and Figure 26 As shown, a chip holder 60 is provided on the printing consumable 10, and the chip 20 can be installed on the printing consumable 10 by cooperating with the chip holder 60.

[0228] The first notch 15 can contact any part of the +Y side or the -Y side of the corresponding contact pin 91a. Specifically, in this embodiment, the second side terminal can be configured to contact the +Y side of the first part 911a of the contact pin 91a.

[0229] Example 8

[0230] See Figures 28 to 31 As shown, the chip 20 provided in this embodiment includes a base portion 21 and a contact component for contacting a stylus 91a. The base portion 21 is provided with an outer surface 211 near the stylus holder 91. The contact component includes at least one external terminal 22 provided on the outer surface 211 that contacts the tip 9111 of the stylus holder 91 corresponding to the stylus 91a. The base portion 21 is also provided with a memory 23 that is electrically connected to the external terminal 22.

[0231] The contact assembly also includes at least one side connection 24 electrically connected to the memory, which can contact the side 9112 of the corresponding stylus 91a in a second direction. The contact portion of the side connection and the corresponding stylus 91a is located on the side of the outer surface 211 away from the stylus holder 91.

[0232] The second direction is the width direction of the printing consumable 10, and the second direction is the same as the Y direction.

[0233] The outer surface 211 is the outer surface with the largest area on the base portion 21, and the outer surface 211 is parallel to the YZ surface. The base portion 21 is a flat plate, and the base portion 21 has an inner surface 212 that is parallel to the outer surface 211. The inner surface 212 is disposed away from the stylus holder 91 relative to the outer surface 211.

[0234] The base portion 21 has at least one through hole 218 that penetrates the outer surface 211 and the inner surface 212. The base portion 21 has a memory 23 disposed on the inner surface 212.

[0235] The side contact portion 24 is a third conductive element provided on one side of the inner surface 212. The projection of the contact portion of the third conductive element and the corresponding contact pin 91a on the outer surface 211 is located at the edge of the projection of the through hole 218 on the outer surface 211.

[0236] Furthermore, the contact assembly includes a data terminal, a clock terminal, a power terminal, a reset terminal, and a ground terminal. The contact portion between the data terminal and the corresponding pin 91a is a data contact portion, the contact portion between the clock terminal and the corresponding pin 91a is a clock contact portion, the contact portion between the power terminal and the corresponding pin 91a is a power contact portion, the contact portion between the reset terminal and the corresponding pin 91a is a reset contact portion, and the contact portion between the ground terminal and the corresponding pin 91a is a ground contact portion.

[0237] The contact portion between the side contact portion 24 and the corresponding contact pin 91a is at least one of the following: data contact portion, clock contact portion, power contact portion, reset contact portion, and ground contact portion.

[0238] In some examples, the third conductive element includes a fixed portion 246 and a movable portion 247. The fixed portion 246 is fixedly connected to the base portion 21 and electrically connected to the memory 23. The movable portion 247 can move in a direction parallel to the inner surface 212. When the printing consumable 10 is installed, the movable portion 247 can abut against the portion of the corresponding stylus 91a that protrudes through the through hole 218.

[0239] like Figure 32 and Figure 34 As shown, the chip 20 needs to be installed with its outer surface 211 facing away from the printing consumable 10. At this time, the outer surface 211 corresponds to the front side of the base portion 21, and the inner surface 212 corresponds to the rear side of the base portion 21. The side portion 24 on the rear side of the base portion 21 can act as a terminal. The corresponding contact pin 91a needs to pass through the through hole 218 and make contact with the side portion 24 on the side surface 9112. Therefore, the contact pin 91a and the chip 20 have a surface-to-surface contact, resulting in a relatively stable electrical connection.

[0240] Furthermore, considering that the rear and front sides of the base portion 21 can only be connected through the through hole 218, and that the outer surface 211 is parallel to the plumb line (i.e., the -Z direction) when the printing consumable 10 is installed, ink droplets or conductive foreign matter adhering to the outer surface 211 cannot pass through the through hole 218 to reach the contaminated side connection portion 24 on the rear side of the base portion 21 without external force intervention. Therefore, a short circuit is less likely to occur between the side connection portion 24 and the external terminal 22. Thus, the aforementioned chip 20 has a lower risk of short circuits between terminals during use compared to the original chip 20.

[0241] The through hole 218 provides a certain limiting effect on the stylus 91a, and the side connection portion 24, which contacts the side of the stylus 91a, also provides a limiting effect on the stylus 91a. In this embodiment, the side connection portion 24 provided on the inner surface 212 serves as a terminal, and the base portion 21 provides a narrow through groove extending in the Z direction as the through hole 218 at the corresponding position. Therefore, it provides a certain limiting effect on the stylus 91a in both the ±Y directions. The side connection portion 24 contacts the -Y side of the corresponding stylus, thus providing a certain suppression effect on the offset of the printing consumable 10 (refer to the aforementioned printing consumable 10) equipped with the chip 20 in the +Y direction. Therefore, by introducing the chip 20, the cooperation between the printing consumable 10 and the stylus holder 91 can be strengthened, thereby limiting the offset of the printing consumable 10 in the mounting portion (refer to the aforementioned mounting portion 90) along the Y-axis direction.

[0242] In some embodiments, any external terminal 22 on the chip 20 may also be electrically connected to the corresponding contact pin 91a by means of an electrical connection between the side portion 24 and the corresponding contact pin 91a.

[0243] The through hole 218 has a mating edge 218a on its inner surface 212 that can mate with the side surface 9112 of the corresponding stylus 91a. When the printing consumable 10 is installed, the side surface 9112 of the corresponding stylus 91a has a protruding portion extending out of the inner surface 212. This side surface 9112 abuts against the mating edge 218a, and the projection of the movable part 247 on the inner surface 212 partially coincides with the mating edge 218a. (See also...) Figures 32 to 34 as well as Figure 29 , Figure 31 In this embodiment, the stylus 91a, when the printing consumable 10 is installed, has a protruding portion 914d that protrudes from the inner surface 212. The protruding portion 914d abuts against the mating edge 218a and the movable portion 247 on the same side. In addition, to ensure stable contact between the side connection portion 24 and the corresponding stylus 91a when installed, it is necessary to ensure that the projection of the movable portion 247 on the inner surface 212 is partially located within the through hole 218 when the side connection portion 24 is in its free state.

[0244] See Figures 28 to 34In this embodiment, the third conductive element is a thin sheet metal part integrally bent, having a relatively long movable portion 247 and a relatively short fixed portion 246. The side of the movable portion 247 is perpendicular to the inner surface 212, and its projection on the inner surface 212 in the free state is slightly inclined relative to the Z-axis toward the through hole 218. Furthermore, the projection of the movable portion 247 on the XZ plane is slightly inclined relative to the base portion 21 in the -X direction. The movable portion 247 has an abutment portion 248 at its movable end, similar to the ridge region of the stylus 91a. The length of the abutment portion 248 in the X direction is greater than the length of other parts of the movable portion 247 in the X direction. The abutment portion 248 is the part of the third conductive element that actually contacts the corresponding stylus. The contact portion of the third conductive element with the corresponding stylus is located on the +Y end side of the abutment portion 248. The fixing part 246 and the base part 21 are attached and connected to each other on the inner surface 212. An internal terminal (not shown in the figure) electrically connected to the memory 23 is provided on the inner surface 212 in the area overlapping with the fixing part 246. The fixing part 246 can be attached to the inner surface 212 by welding or bonding with conductive adhesive to ensure electrical connection with the internal terminal. Furthermore, to ensure sufficient contact area between the third conductive element and the through-hole, the chip 20 needs to use a thinner base part 21, i.e., a base part 21 with a smaller X-axis dimension.

[0245] In this embodiment, four external terminals 22 can be provided on the external surface 211. Each of the four external terminals 22 has a first contact portion 221. These four contact portions are disposed on the external surface 211 using a surface copper plating process and only slightly protrude from the external surface 211, so they can be regarded as being located on the external surface 211. The four external terminals 22 are arranged in two rows, namely a first row and a second row. The first row has one external terminal 22, and the second row has three external terminals 22. The line connecting the first contact portions 221 of the three external terminals 22 in the second row is a straight line.

[0246] like Figure 34 As shown, the third conductive element has a second contact portion 244a, which is located on the side corresponding to the inner surface 212 of the chip 20. Its position in the X direction is different from that of the other contacts. Therefore, the second contact portion 244a cannot be considered as being located on the outer surface 211. Furthermore, since the stylus 91a corresponding to the second contact portion 244a hardly deforms in the X direction when the printing consumable 10 is installed, the position of the second contact portion 244a in the Z direction is different from that of the first contact portion 221. The line connecting its projection on the outer surface 211 and the first contact portion 221 is not parallel to the line connecting the first contact portions 221 of the three external terminals 22 on the second row.

[0247] In addition, such as Figure 31 and Figure 33As shown, because the through hole 218 has a fitting edge 218a, when the chip 20 is viewed along the -X direction while the printing consumable 10 is installed, the third conductive element cannot be observed from the through hole 218, nor can the corresponding second contact portion 244a be observed. To further ensure that the second contact portion 244a cannot be observed from the -X viewpoint, the chip 20 can be installed on the consumable body of the printing consumable 10 at a slight tilt. Specifically, the outer surface 211 is slightly deflected relative to the YZ plane, so that the -Y side of the outer surface 211 is closer to the ink cartridge than the +Y side.

[0248] To reduce interference between the stylus 91a and the through hole 218 when the printing consumable 10 is removed, in a specific implementation, the -Z end sidewall of the through hole 218 can be set as a slope, and the through hole 218 can also extend along the -Z direction to the -Z end edge of the base portion 21.

[0249] like Figure 28 As shown, a positioning part is also provided on the base portion 21. The positioning part includes a positioning notch 215 located on the edge of the base portion 21 and a positioning through hole 216 located on the base portion 21. The positioning part is used to cooperate with the protrusion on the printing consumable for positioning, so as to facilitate the positioning and installation of the chip 20. In this embodiment, the positioning notch 215 is located on the +Z side edge of the base portion 21, and the positioning through hole 216 is located on the -Z side of the base portion 21.

[0250] Optionally, such as Figure 28 As shown, the chip 20 also includes a shielding component 26, which is attached to and connected to the outer surface 211 to shield the through hole 218. The projection of the side contact portion 24 and the corresponding contact pin 91a on the outer surface 211 is located within the projection range of the shielding component 26 on the outer surface 211.

[0251] The shielding component 26 covers the through hole 218 and has a cutout 261 through which the contact pin 91a can pass to contact the side connection portion 24. The shielding component 26 isolates the side connection portion 24 from other terminals, preventing short circuits and reducing the risk of short circuits between the terminals of the chip 20, thus improving the safety of the chip.

[0252] The shielding component 26 can be an elastic membrane. When the stylus 91a is inserted into the cut 261 of the shielding component 26, the stylus 91a squeezes the shielding component 26, causing the cut 261 to open; when the stylus 91a is withdrawn from the shielding component 26, the squeezing force of the stylus 91a on the shielding component 26 is removed, and the shielding component 26 returns to a closed state under its own action, causing the cut 261 to close.

[0253] Example 9

[0254] See Figures 35 to 37 The chip 20 provided in this embodiment includes a base portion 21 and a contact component for contacting a stylus 91a. The base portion 21 is provided with an outer surface 211 near the stylus holder 91. The contact component includes at least one external terminal 22 provided on the outer surface 211 that contacts the tip 9111 of the stylus holder 91 corresponding to the stylus 91a. The base portion 21 is also provided with a memory 23 that is electrically connected to the external terminal 22.

[0255] The contact assembly also includes at least one side connection 24 electrically connected to the memory. The side connection can contact the side surface 9112 of the corresponding stylus 91a in the second direction S. The contact portion of the side connection and the corresponding stylus 91a is located on the side of the outer surface 211 away from the stylus holder 91.

[0256] The second direction is the width direction of the printing consumable 10, and the second direction S and the Y direction are the same.

[0257] The printing consumable 10 is provided with a chip holder 60, and the chip 20 can be installed on the printing consumable 10 by cooperating with the chip holder 60.

[0258] like Figure 35 and Figure 39 As shown, the base portion 21 includes an intersecting first plate 21c and a second plate 21d. The surface of the first plate 21c facing away from the chip holder 60 is the outer surface 211, and the side of the second plate 21d facing the chip holder 60 is the inner surface 421d. A second notch 16 is provided at the intersection of the first plate 21c and the second plate 21d along the first direction P. The second notch 16 has an opening end that penetrates the first plate 21c at one end in the first direction P.

[0259] The first plate 21c has an inner surface 212 opposite to the outer surface 211. The second plate 21d is located on the inner surface 212 side of the first plate 21c. The side contact portion 24 is provided on the side of the second plate 21d near the inner surface 212. The side contact portion 24 and the second notch portion 16 partially overlap in the first direction P. The projection of the contact portion 24 and the corresponding contact pin 91a on the outer surface 211 is located at the edge of the projection of the second notch portion 16 on the outer surface 211.

[0260] The area of ​​the outer surface 211 is larger than that of the inner surface 421d. The inner surface 212 is provided with a memory 23 that is electrically connected to the outer terminal 22 and the side connection 24. The inner surface 212 is parallel to the outer surface 211. The angle α between the inner surface 212 and the inner surface 421d is a right angle or an obtuse angle.

[0261] In specific implementation, assuming the first plate 21c is a flat plate and the side surface 9112 of the stylus 91a is perpendicular to the first plate 21c, when the angle α between the inner surface 212 and the inner contact surface 421d is a right angle, the side contact portion 24 is a first side terminal disposed on the inner contact surface 421d, allowing the stylus 91a to directly contact the first side terminal; when the angle α between the inner surface 212 and the inner contact surface 421d is an obtuse angle, the side contact portion 24 can be configured as an elastic conductive element on the inner contact surface 421d to ensure stable contact with the corresponding stylus 91a. In both of the above cases, when observing the second notch portion 16 from a perspective perpendicular to the outer contact surface 211, the side contact portion 24 and its contact portion are not visible. The side connector 24 contacts the side of the corresponding pin 91a, which is a surface-to-surface contact. The contact area is relatively large and parallel to the side 9112. The pin corresponding to the side connector 24 can suppress the displacement of the electrical connection assembly composed of the chip 20 and the chip holder 60 in the width direction of the printing consumable 10, thereby suppressing the overall displacement of the printing consumable 10 in its width direction during installation. The external terminal 22 has a point contact with the corresponding pin. The contact area corresponds to the tip 9111 of the pin 91a and has a small area. During installation, the pin 91a undergoes elastic deformation, and the displacement of the electrical connection assembly can only be limited by static friction with the chip 20, resulting in a poor limiting effect. Because it contains the side connector 24 that contacts the side 9112 of the pin 91a, the connection between the above-mentioned electrical connection assembly and the pin holder 91 is more stable and reliable compared to the electrical connection assembly with the original chip 20.

[0262] In this embodiment, the base portion 21 can be a flexible circuit board, therefore it needs to be used in conjunction with the chip holder 60 to maintain the stable shape of the substrate base portion 21. In this embodiment, the first plate 21c and the second plate 21d intersect approximately perpendicularly and form a clear intersection line. The second notch portion 16 is provided along this intersection line. In specific implementation, in order to prevent the internal circuits of the flexible circuit board from being broken, the part of the first plate 21c adjacent to the second plate 21d can be set as a transition portion with a certain curvature. In this case, the second notch portion 16 needs to be set on this transition portion.

[0263] Optionally, such as Figure 34 and Figure 35 As shown, four external terminals 22 can be provided on the external surface 211, and each of the four external terminals 22 has a first contact portion 221. The first side terminal has a second contact portion 244a.

[0264] The first panel 21c is an arc-shaped panel, and the outer surface 211 is roughly cylindrical. Figure 37 The axis corresponding to the outer surface 211 is shown by the dashed line, so the four first contact parts 221 are not actually on the same plane.

[0265] The second plate 21d is located on the +Y side of the first plate 21c and is a flat plate that is approximately perpendicular to the first plate 21c. Therefore, the second contact portion 244a is not on the same plane as the other four first contact portions 221. Furthermore, in the state where the printing consumable 10 is installed, since the corresponding stylus 91a hardly deforms in the X direction, the position of the second contact portion 244a in the Z direction is also significantly different from the first contact portions 221 of the four external terminals 22, and it is also possible to achieve non-overlap with the first contact portions 221 in the Z direction.

[0266] To further ensure that the contact pin 91a can directly contact the side contact portion 24, in addition to setting α to approximately a right angle, an auxiliary structure can be introduced on the chip holder 60 to guide the contact pin 91a to contact the side contact portion 24 and maintain the contact state between the contact pin 91a and the side contact portion 24. For example... Figure 36 and Figure 38 As shown, in this embodiment, the chip holder 60 includes a receiving portion 611 that mates with the chip. The receiving portion 611 has a guiding cavity 612 that guides the stylus 91a to contact the side receiving portion 24. The guiding cavity 612 communicates with the second notch portion 16. The -Z end of the guiding cavity 612 is an open end. On the side of the guiding cavity 612 facing the inner surface 421d, there are intersecting guiding inclined walls 612a and limiting side walls 612b. The guiding inclined wall 612a is located on the -Z side of the limiting side wall 612b. The distance from the +Z end of the guiding inclined wall 612a to the inner surface 421d is less than the distance from the -Z end of the guiding inclined wall 612a to the inner surface 421d. When the printing consumable 10 is installed, the stylus 91a is located between the limiting side wall 612b and the side receiving portion 24, and both sides of the stylus 91a abut against the side receiving portion 24 and the limiting side wall 612b, respectively. The introduction of the guide cavity 612 further enables the electrical connection assembly to restrict the offset of the corresponding printing consumable 10 within the mounting position in the width direction (±Y direction) of the printing consumable 10. In this embodiment, the guide cavity 612 can be understood as applying the limiting part 11b in embodiment four to the chip holder 60, the guide inclined wall 612a is equivalent to the guide surface 111 of the limiting part 11b in embodiment four, and the limiting side wall 612b is equivalent to the limiting surface 112 of the limiting part 11b in embodiment four.

[0267] In this embodiment, as Figure 35 As shown, the side connection 24 is located on the +Y axis side of the limiting sidewall 612b.

[0268] It should be noted that in some embodiments, the second plate 21d can also be disposed on the -Y side of the first plate 21c, and the second notch 16 needs to be disposed on the -Y side edge of the first plate 21c. In this case, the terminal on the chip 20 near the -Y side can be disposed as a side connection 24, and the other four terminals can be disposed as external terminals 22. Since the side connection 24 and the four external terminals 22 are not coplanar, and there is a second notch 16 between the side connection 24 and the four external terminals 22 to act as a gap, conductive foreign objects (ink droplets, solid debris, etc.) are not likely to conduct to any one of the four external terminals 22, thus also reducing the risk of short circuit between terminals.

[0269] Optionally, a positioning notch 215 is also provided through the base portion 21 at its edge. The positioning notch 215 is used to cooperate with the positioning protrusion 613 on the receiving portion 611 to facilitate the positioning and installation of the chip 20. In this embodiment, the base portion 21 contains two positioning notches 215, which are located on the +Z side and -Z side edges of the first plate 21c, respectively.

[0270] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
