DETAILED DESCRIPTION OF THE EMBODIMENTS

[0052] As mentioned in the background art, an image forming apparatus includes an ink cartridge and a printing device. When the ink cartridge is inserted into the printing device, the chip of the ink cartridge cannot be grounded or the grounding is unstable, which affects the chip's grounding stability and use safety; according to the inventor research it has been found that the reasons for this problem are as follows:

[0053] During the mounting process of the ink cartridge, the contact pin set of the printing device is exposed in the mounting portion. At this time, when the ink cartridge or foreign objects accidentally fall into the mounting portion and hit the grounding contact pin, the grounding contact pin may be accidentally bent or contacted, its contact point may be friction-damaged, or its position may become unstable, so it cannot ensure stable contact with the grounding terminal of the chip, so there is a possibility that the chip cannot be grounded or the grounding is unstable. Therefore, when the ink cartridge has excessive current, it may damage the chip and the printing device, and may also cause the printing device to be unable to recognize the ink cartridge properly.

[0054] In view of the above technical problems, the embodiments of the present application provide a new ink cartridge, which includes a conductive member and a chip, and the grounding terminal of the chip is electrically connected to the conductive member, which in turn is electrically connected to a grounding component located in the assembly compartment of the printing device. With this arrangement, when the ink cartridge is inserted into the printing device, the chip is electrically connected to the grounding component through its grounding terminal, conductive member, and the chip is stably grounded.

[0055] With this arrangement, the ink cartridge in the embodiment of the present application connects the grounding terminal of the chip to the grounding component through the conductive member, which can avoid the unstable contact between the grounding terminal and the grounding contact pin, resulting in the chip being unable to be grounded or the grounding being unstable, thus improving the reliability of the chip grounding, preventing excessive current from damaging the chip and the printing device, improving the safety of the ink cartridge and the printing device, and reducing the possibility that the printing device cannot recognize the ink cartridge.

[0056] In order to make the above purposes, features and advantages of the embodiments of the present application more obvious and easier to be understood, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The chip is provided with a communication terminal group and a grounding terminal, where the communication terminal group is electrically connected to the contact pin assembly. The conductive member is arranged within the assembly compartment and is configured to electrically connect the grounding terminal to the grounding component.

[0061] The contact pins in the contact pin assembly can deform, but the grounding component cannot deform; when the chip contacts the contact pins, at least one contact pin deforms; when the conductive member contacts the grounding component, the grounding component does not deform. It should be noted that since any two objects come into contact, their contact surfaces will deform. Therefore, the "non-deformability" of the grounding component in this embodiment means that compared with the large deformation of the contact pin, the tiny deformation invisible to the naked eye occurs when the grounding component and the conductive member come into contact.

[0062] The ink cartridge 10 includes an ink cartridge body 50, a chip 20 and a conductive member. The ink cartridge body 50 is used to hold ink, and the chip 20 is disposed on the surface of the ink cartridge body 50. The chip 20 is used to store the manufacturer information, ink volume information, ink cartridge category information, ink color information or the like. The chip is equipped with a plurality of terminals. According to the purpose of the terminals, the plurality of terminals can be divided into communication terminals and grounding terminals. That is, the chip is equipped with a communication terminal group and a grounding terminal. The communication terminal group includes a plurality of communication terminals.

[0063] Further, the communication terminal is configured to contact and electrically connect with each contact pin of the contact pin assembly. The grounding terminal is connected to one end of the conductive member, and the other end of the conductive member can be connected to the grounding component, so that the ground signal of the chip can be transmitted to the grounding component through the conductive member, thereby completing the grounding.

[0064] When the ink cartridge 10 is inserted into the accommodation cavity, each communication terminal of the chip 20 contacts and is electrically connected with the corresponding contact pin assembly, so that data transmission, confirmation, data interaction, etc. can be performed between the ink cartridge 10 and the printer. At the same time, the conductive member is electrically connected to the grounding component, so that the ink cartridge and the printer are both grounded.

[0065] Compared with the related art solution in which the grounding terminal of the chip 20 is electrically connected to the corresponding grounding contact pin in the contact pin assembly, the ink cartridge in the embodiment of the present application connects the grounding terminal of the chip to the grounding component through a conductive member. It can avoid the unstable contact between the grounding terminal and the grounding contact pin, which will cause the chip to be unable to be grounded or the grounding is unstable. Therefore, it can improve the reliability of the chip grounding, prevent excessive current from damaging the chip and the printing device, and enhances the operational safety of both the chip and the printing device while reducing the likelihood of the printing device failing to recognize the ink cartridge.

[0066] Based on the above embodiments, in the embodiment of the present application, the mounting portion can be fixed in the assembly compartment, or the mounting portion can be movably mounted in the assembly compartment, for example, the mounting portion can be slidably mounted on the assembly compartment. However, due to the different arrangement of the mounting portion in the assembly compartment, it affects the mounting mode between the ink cartridge and the mounting portion. Furthermore, the arrangement of the chip on the ink cartridge and the electrical connection scheme of the conductive member and the grounding component are also different. These distinctions will be elaborated in separate embodiments within this application.Embodiment 1:

[0067] In the embodiment of the present application, the mounting portion is disposed in the assembly compartment, and the grounding component is disposed in the accommodation cavity of the mounting portion; specifically, the mounting portion can be movably mounted on the assembly compartment.

[0068] In the first implementation, this implementation provides an antenna-type conductive member, and the metal piece disposed in the assembly compartment is configured as a grounding component, that is, the metal piece is grounded; one end of the conductive member is connected to the grounding terminal of the chip 20, and the other end is connected to the grounding component, and the electrical connection point between the two is located above the chip.

[0069] Continuing to refer to Figure 3, the mounting portion is a component of the printing device and is used to hold one or more ink cartridges. The ink cartridges are detachably mounted onto the mounting portion along the mounting direction P. When the ink cartridges are used up, they need to be replaced with new ones.

[0070] The ink cartridge 10 includes a chip 20, a handle 30, an ink outlet 41 and an ink cartridge body 50. The mounting portion 90 has a contact pin assembly 91, an ink supply portion 92, an opening 95, and a bottom wall 90a. The ink cartridge 10 is mounted onto the mounting portion 90 from the opening 95 along the mounting direction P (-Z axis direction). The handle 30 is used to fix the ink cartridge 10 to the mounting portion 90 and prevent the ink cartridge 10 from being detached from the mounting portion 90.

[0071] Ink is stored in the cartridge body 50 (also referred to as the ink cartridge body 50), and the ink reaches the ink supply portion 92 through the ink outlet 41, and then the ink supply portion 92 can supply the ink to the print head of the printer, thereby the ink can be used for performing the printing operations.

[0072] As shown in Figure 4, the contact pin assembly 91 includes a contact pin 91a and a base 910, and the contact pin 91a is disposed on the base 910. The chip 20 is provided with a communication terminal group, which can be electrically connected to the contact pins of the contact pin assembly for mutual transmission of electrical signals.

[0073] In this embodiment, a three-dimensional rectangular coordinate system is set, that is, an XYZ axis coordinate system. The three-dimensional rectangular coordinate system of the ink cartridge is consistent with the three-dimensional rectangular coordinate system of the mounting portion. The direction in which the ink cartridge 10 is mounted to the mounting portion is the -Z axis direction, the direction in which the ink cartridge is detached from the mounting portion is the +Z axis direction, the opening is located in the +Z axis direction, and the bottom wall 90a is located in the -Z axis direction. Generally, the printer is placed flat on an office desk or printing desktop, with the opening 95 located at the top of the mounting portion 90 and the bottom wall 90a located at the bottom of the mounting portion 90. This arrangement facilitates the user to mount or remove the ink cartridge.

[0074] Furthermore, the mounting portion 90 can hold one or more ink cartridges, and the mounting portion has one or more mounting positions. For example, the mounting portion 90 has four mounting positions, each of which can be inserted into one mounting position, and four ink cartridges can store four different colors of ink, such as black, yellow, blue, and red.

[0075] The mounting portion provided in this implementation is a component with an opening, approximately in the shape of a cuboid or a cube, and the inner wall and the bottom wall 90a of the mounting portion constitute the mounting position. The contact pin assembly 91 is mounted on the first side wall 90c of the mounting portion. The mounting positions are arranged in sequence in the Y axis direction, and the four mounting positions are arranged in sequence in the Y axis direction. The direction perpendicular to the Y axis and the Z axis is the X axis direction, and the direction from the inside of the mounting portion 90 to the contact pin assembly 91 is the +X axis direction. The +X axis is perpendicular to the first side wall 90c. Viewing along the +X axis direction, on the YZ plane, when the +Z axis is above, the +Y axis direction is on the left.

[0076] Continuing to refer to Figure 4, the contact pin assembly 91 has a base 910 and a plurality of contact pins mounted on the base 910. For example, the base 910 is provided with five contact pins, the five contact pins are the first contact pin 911 to the fifth contact pin 915 respectively. Each contact pin is a thin metal sheet, which can conduct electricity and is wear-resistant. Accordingly, the base 910 has a plurality of slits 981-985 corresponding to the contact pins. Among them, the slits 981, 982, 983, 984, and 985 correspond to the contact pins 911, 912, 913, 914, and 915 respectively. The plurality of slits 981-985 are all U-shaped and have slit openings in the +Z axis direction, a plurality of contact pins 911-915 are respectively mounted onto the slits 981-985 through the slit opening along the -Z axis direction.

[0077] Specifically, the first contact pin 911 is mounted onto the first slit 981 through the slit opening along the -Z axis direction; the second contact pin 912 to the fifth contact pin 915 are mounted on the same manner, which will not be repeated here. One side of each of the first contact pins 911 to the fifth contact pins 915 is connected to the main circuit of the printer through the internal circuit of the mounting portion, and the other side is exposed in the accommodation cavity of the mounting portion 90, and when the ink cartridge is inserted into the accommodation cavity, it can be electrically connected to each communication terminal of the chip 20.

[0078] In the embodiment of the present application, the structures of the first contact pin 911 to the fifth contact pin 915 are the same. This embodiment uses the first contact pin 911 as an example to illustrate the structure of each contact pin. As shown in Figure 5, the first contact pin 911 is divided into a first part 911a, a second part 911b and a third part 911c. The first part 911a is used to electrically connect with the communication terminal of the chip 20 and form a first contact portion; the second part 911b is connected to the internal circuit of the printer.

[0079] 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 first contact pin 911. The first contact pin 911 passing through the third part 911c or as a part of the third part 911c (for example, the horizontal part 911h of the third part 911c) is fixed to the first slit 981. The first part 911a and the second part 911b are provided at the end of the first contact pin 911 in the -Z axis direction, so that the first part 911a and the second part 911b can be elastically deformed and can easily return to their original shape after deformation. The first part 911a of the first contact pin 911 is arranged in the -X axis direction, and the second part 911b is arranged in the +X axis direction. The first part 911a and the second part 911b protrude from the base 910, and the third part 911c does not protrude from the base 910.

[0080] Further, the first part 911a and the second part 911b protrude from the base 910 in the X axis direction, and the base 910 is 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, that is, the first part 911a can be electrically connected to the chip 20.

[0081] The third part 911c includes a first vertical part 911k and a second vertical part 911j perpendicular to the X axis direction, and a horizontal part 911h parallel to the X axis direction, where the horizontal part 911h connects the first vertical part 911k and the second vertical part 911j. The first vertical part 911k and the second vertical part 911j extend up and down along the Z axis direction. The first vertical part 911k is closer to the mounting position than the second vertical part 911j, the end of the first vertical part 911k is connected to the first part 911a, the end of the second vertical part 911j is connected to the second part 911b, the horizontal part 911h or the first vertical part 911k and the second vertical portion 911j are fixed to the first slit 981 in the +Z axis direction.

[0082] Continuing to refer to Figure 5, the first part 911a includes a first surface part 911a1, a second surface part 911a2, a third surface part 911a3 and a fourth surface part (not shown in the figure), where the third surface part 911a3 and the fourth surface part are arranged oppositely along the X direction, the area enclosed by the first surface portion 911a1 and the second surface portion 911a2 forms a ridge area, and the first vertical portion 911k is a vertical area, the second part 911b is another ridge area, and the second vertical part 911j is another vertical area. The second contact pins 912 to the fifth contact pins 915 have the same arrangement and structure as the first contact pins 911, which will not be described again here.

[0083] As shown in Figures 6 and 7, the chip 20 provided in this embodiment has a memory 100, a substrate 120, and a plurality of terminals 130 (communication terminal group). The substrate 120 has a front surface 120a, a rear surface 120b, a left side 120c, a right side 120d, a top surface 120e (not shown in the figure), and a bottom surface 120f.

[0084] Among them, the front surface 120a and the rear surface 120b are arranged oppositely, and the front surface 120a is located on the +X side of the rear surface 120b; the left side 120c is arranged opposite to the right side 120d, and the left side 120c is located on the -Y side of the right side 120d; the top surface 120e and the bottom surface 120f are arranged oppositely, and the top surface 120e is located on the +Z axis side of the bottom surface 120f.

[0085] Furthermore, a plurality of terminals 130 are provided on the front surface 120a, so the front surface 120a is also called the first terminal surface. For example, the first terminal 131, the second terminal 132, the third terminal 133 and the fourth terminal 134 are provided on the front surface 120a, and the first terminal 131, the second terminal 132, the third terminal 133 and the fourth terminal 134 are on the Y axis. The positions are different. The first terminal 131 and the fourth terminal 134 have the same position on the Z axis. The second terminal 132 and the third terminal 133 have the same position on the Z axis. However, the first terminal 131 and the third terminal 133 have the different positions on the Z axis.

[0086] Further, the first terminal 131, the second terminal 132, the third terminal 133 and the fourth terminal 134 are all configured as communication terminals. The first terminal 131 (data terminal) is configured to transmit or receive data signals; the second terminal 132 (clock terminal) is configured to be a clock terminal for receiving a clock signal; and the third terminal 133 (power terminal) is configured to provide operating voltage to the memory 100; the fourth terminal 134 (reset terminal) is used to reset the internal data of the memory 100.

[0087] Each communication terminal has a contact portion C, which is represented by a circle. The plurality of communication terminals have a plurality of contact portions C, which are respectively the first contact portion C1 to the fourth contact portion C4. Contact portion C is the most likely contact area of the contact pin on the terminals 130 when the ink cartridge 10 is mounted on the printer.

[0088] The communication terminal group includes a data terminal (first terminal 131), a reset terminal (fourth terminal 134), a power terminal (third terminal 133), and a clock terminal (second terminal 132); along the mounting direction P of the ink cartridge 10 to the printing device, the contact portions C1-C4 where each terminal of the communication terminal group contacts the contact pin assembly are arranged in two rows.

[0089] In the mounting direction P (i.e., the Z axis direction in the figure), the contact portion C1 of the data terminal and the contact portion C4 of the reset terminal are disposed on the upstream side; the contact portion C3 of the power terminal and the contact portion C2 of the clock terminal are disposed on the downstream side.

[0090] In the embodiment of the present application, the memory 100 and the above-mentioned communication terminals are respectively disposed on the substrate 120. The memory 100 needs to be grounded and can be regarded as a "grounding terminal". The memory 100 needs to transmit and interact with the ground signal with the printing device so that the ink cartridge can be mounted onto the printing device normally and perform corresponding tasks.

[0091] It should be noted that the memory 100 is used to store information such as manufacturer information, ink volume information, ink cartridge type information, ink color and other information. When the ink cartridge 10 is mounted onto the mounting portion of the printer, data transmission, confirmation, data interaction, etc. will be performed between the memory 100 and the printer, and the two are realized through the connection between the communication terminal and each contact pin of the printer.

[0092] Further, the memory 100 may be disposed on any one or several surfaces from the front surface 120a to the bottom surface 120f. Preferably, the memory 100 is disposed on the rear surface 120b. The specific shape and structure of the substrate 120 is not limited, and those skilled in the art can set it according to specific design requirements. For example, the chip 20 can be set as a rectangular structure, a cut-corner rectangular structure, a rounded rectangular structure, a T-shaped structure, a trapezoidal structure, a parallelogram structure.

[0093] In addition, the location of the memory 100 on the substrate 120 is not limited. For example, the memory 100 can be disposed on the side of the chip 20 close to the rear end of the -Z axis, or the memory 100 can also be disposed on the chip 20 close to the direction -Z axis. On one side of the front end of the +Z axis, the memory 100 can also be disposed in the middle of the chip 20. Those skilled in the art can configure the specifics according to the specific design requirements and it will not be described here for conciseness.

[0094] Continuing to refer to Figure 6, in this embodiment, the memory 100 is disposed on the rear surface 120b and is disposed close to the right side 120d and the top surface 120e. The connector 135 (also called a conductive member) is made of a conductive material with a certain hardness, and is connected to the conductive sheet 135a (also called a grounding terminal) through solder. The conductive sheet 135a (also called a grounding terminal) is connected to the memory 100 through the built-in circuit / conductive line of the substrate 120, thereby connecting the connector 135 to the memory 100.

[0095] The conductive sheet 135a (can also be called a grounding terminal) can be regarded as a part of the chip 20. Specifically, the conductive sheet 135a (can also be called a grounding terminal) can be copper coating (implemented by electroplating process) on the chip 20, and can electrically connect the conductive member 135 and the memory 100. The connector 135 (also called a conductive member) can be welded or contacted with the conductive sheet 135a (also called a grounding terminal) or in other contact forms, as long as it can be electrically connected.

[0096] The connector 135 (which may also be referred to as a conductive member) is disposed in the assembly compartment, and the connector 135 is configured to electrically connect the conductive sheet 135a (which may also be referred to as a grounding terminal) and the grounding component. Furthermore, the ground signal is transmitted between the ink cartridge 10 and the printing device through the grounding terminal 135a, the conductive member 135, and the grounding component. Optionally, the ground signal is transmitted between the ink cartridge 10 and the printing device through the memory 100, the conductive member 135, and the grounding component on the chip. Furthermore, the ground signal is transmitted between the ink cartridge 10 and the printing device through the memory 100, the grounding terminal 135a, the conductive member 135, and the grounding component on the chip.

[0097] Since the connector 135 (which can also be called a conductive member) is electrically connected to the chip memory 100 and the grounding terminal 135a, the connector 135 (which can also be called a conductive member) can also be regarded as the chip 20. That is, the chip 20 includes the memory 100, the substrate 120, the communication terminal group 130, the conductive member 135, and the grounding terminal 135a.

[0098] The contact pins 911-914 in the contact pin assembly 91 can deform, but the grounding component cannot deform; when the chip 20 contacts the contact pins 911-914, at least one contact pin deforms; when the conductive member 105 contacts the grounding component, the grounding component does not deform, and small deformations invisible to the naked eye are also non-deformable. This structure helps ensure the stability of the transmission of electrical signals of the chip 20, especially the ground signal.

[0099] It should be noted that the ground signal is usually output by the main CPU of the printing device, and the ground signal is output by the main CPU to the grounding contact pin, grounding component, etc. of the contact pin assembly. When the ink cartridge is mounted on the printing device, the ground signal communication between the ink cartridge and the printing device must be maintained. In the related art, ground signals are transmitted between the ink cartridge and the printing device through the ground sub-terminals and grounding contact pins of the chip terminal group.

[0100] However, in this application, the ground signal is transmitted through the grounding terminal, the conductive member, and the grounding component. Optionally, this application transmits the ground signal through the memory, conductive members (also called connectors), on the chip and grounding components. Optionally, this application transmits the ground signal through the memory, grounding terminal, conductive member (also called a connector) on the chip, and grounding component, which can improve the stability of the ground signal transmission.

[0101] This embodiment describes in detail the communication terminal group provided on the chip and the layout of the grounding terminal on the chip substrate.

[0102] As shown in Figure 7, the chip 20 in this embodiment includes a substrate 120, and the substrate 120 includes a first surface 120a and a second surface 120b that are oppositely arranged. The first surface 120a and the second surface 120b, where the first surface 120a is the substrate 120, and the front surface 120b is the rear surface of the substrate. The first surface 120a is configured as a surface of the substrate close to the contact pin assembly 91 of the printer. The first surface 120a is provided with a communication terminal group, and the communication terminal group includes a plurality of communication terminals 131-134.

[0103] Further, the chip further includes a grounding terminal 135a. The grounding terminal 135a is disposed on the first surface 120a or the second surface 120b. The grounding terminal 135a is electrically connected to the conductive member 135 and forms a grounding point of the chip.

[0104] In one embodiment, the first surface 120a has a first direction and a second direction that are orthogonal to each other, and the first direction is configured as a mounting direction of the ink cartridge 10 to the printing device. Each communication terminal is provided with a first contact portion that contact with the contact pins. The first contact portion has a first projection on the first surface 120a. The first projections of a plurality of first contact portions collectively form a first region on the first surface 120a. The grounding point formed by the conductive member and the grounding terminal has a second projection on the first surface 120a.

[0105] Along the second direction, at least part of the second projection is located outside the first area. In other words, in the second direction, part of the second projection is located within the first area, and at least part of the second projection is located outside the first area. For example, part of the second projection is located outside the first area. In this case, in the second direction, the second projection is close to one side of the first area, and the distance from the first area is less than the length of the first area. Optionally, in the second direction, the second projection overlaps with the first area.

[0106] The chip 20 can also have the following variations, and different chip variations can be mounted on the ink cartridge 10.Variation 1 of the chip:

[0107] As shown in Figures 8 to 10, the difference between this Variation and the chip of the Embodiment 1 is that the chip 20 provided by this Variation has a memory 100, a substrate 120, and a terminal group (equivalent to the communication terminal group of the Embodiment 1).

[0108] The memory 100 and the terminal group (equivalent to the communication terminal group in the Embodiment 1) are disposed on the chip substrate 120. The memory 100 is used to store information such as manufacturer information, ink volume information, consumable cartridge type information, ink color information or the like. When the consumable cartridge 10 is mounted onto the mounting portion 90 of the printer, data transmission, confirmation, data interaction, etc. will be performed between the memory 100 and the printer, and both are realized through the connection between the terminal group and the printer contact pins. Furthermore, the shape of each terminal in the terminal group may be other shapes, such as: rectangle, square, circle, trapezoid or other irregular shapes.

[0109] In this Variation, a terminal group is disposed on the front surface 120a, and the terminal group includes a plurality of terminals (131-139). Of course, the memory 100 can be disposed on any one or more of the front surface 120a and the bottom surface 120f. In the Z axis direction, the top surface 120e and the bottom surface 120f are disposed opposite to each other. The specific shape and structure of the chip 20 is not limited. Those skilled in the art can set it according to specific design requirements. For example, the chip 20 can be set in a rectangular structure, a cut-corner rectangular structure, a rounded rectangular structure, a T-shaped structure, a ladder structure, parallelogram structure.

[0110] In addition, the location where the memory 100 is disposed is not limited. For example, the memory 100 can be disposed on the side of the chip 20 close to the rear end in the mounting direction, or the memory 100 can also be disposed on the side of the chip 20 close to the front end in the mounting direction, the memory 100 can also be disposed in the middle of the chip 20, and those skilled in the art can set it according to specific design requirements, which will not be described again here.

[0111] In this embodiment, the terminal group includes 9 terminals, and the functions and purposes of each terminal are: the first terminal 131; the second terminal 132 (reset terminal): used to reset the internal data of the wafer; the third terminal 133 (clock terminal): used to receive a clock signal; the fourth terminal 134; the fifth terminal 135; the sixth terminal 136 (power terminal): used to receive a power supply potential different from the ground potential (such as 3.6V), through this terminal the power is supplied to the memory 100; the seventh terminal 137a, 137b, 137c, 137d (grounding terminal): used to indirectly receive the ground potential; the eighth terminal 138 (data terminal): used to send or receive data signals, the ninth terminal 139.

[0112] In this embodiment, the third terminal group includes a first terminal 131 and a fourth terminal 134, and the second terminal group includes a fifth terminal 135 and a ninth terminal 139. Both the third terminal group and the second terminal group are mounting detection terminals, where the first terminal 131 and the fourth terminal 134 may also be short circuit detection terminals, and the other terminals may be the first terminal group. When the consumable cartridge 10 is mounted on the printer, electrical signal transmission occurs between the mounting detection terminal and the printer to detect whether the consumable cartridge 10 is mounted. In addition, the fifth terminal 135 and the ninth terminal 139 are also called high-voltage terminals and are used to receive the mounting detection voltage (for example, 42V) to complete the mounting detection function of mounting the consumable cartridge to the mounting portion.

[0113] For example, a high resistor (for example: 62kΩ) is connected between the fifth terminal 135 and the ninth terminal 139 to determine whether the consumable cartridge 10 has been mounted on the mounting portion by detecting changes in current or voltage. First terminal 131, fourth terminal 134: also called short circuit detection terminal, it detects whether there is a short circuit on the chip 20 by detecting the voltage change on the terminal; at the same time, it can be determined whether the consumable cartridge 10 is mounted on the printer by whether the two are connected.

[0114] In addition, the first terminal 131 and the fourth terminal 134 are also used to detect whether a short circuit occurs between the terminals. Specifically, they are used to detect whether a short circuit occurs between the fifth terminal 135 / ninth terminal 139 and the first terminal 131 / fourth terminal 134. When the fifth terminal 135 / ninth terminal 139 is short-circuited to the first terminal 131 / fourth terminal 134, the printer can detect that the voltage on the first terminal 131 / fourth terminal 134 has increased, and then the printer prompts short circuit information to avoid the risk of the chip or printer being damaged due to short circuit.

[0115] Each terminal in the terminal group has its own contact, represented by a dot in Figure 8. The contact area is the most likely contact area on the terminal for the contact pin when the consumable cartridge 10 is mounted on the printer. Viewed along the direction perpendicular to the mounting direction P, the arrangement sequence is the grounding terminal (the seventh terminal 137a, 137b, 137c, 137d), a second contact portion, a third contact portion, the first contact portion, and another third contact portion, another second contact portion, or the grounding terminal and the fifth terminal 135 are in a straight line along the Z direction (as shown in Figure 8). Of course, the grounding terminal may be disposed on the chip front surface 120a or on the rear surface 120b, for example, the grounding terminals can be disposed in four positions: 137a, 137b, 137c, and 137d as shown in Figures 8 and 9. In this embodiment, the grounding terminals 137a, 137b, 137c, and 137d are preferably disposed on the front surface 120a or the rear surface 120b, and is disposed in such a manner that the grounding terminal is located in the +Z direction of the fifth terminal 135 or in the +Z direction toward the -Y direction side.

[0116] Optionally, along the Z direction, the grounding terminal (seventh terminal) and the first terminal 131 are in a straight line. Optionally, along the Z direction, the grounding terminal (seventh terminal) overlaps at least part of the first terminal 131 and the fifth terminal 135. Optionally, along the Z direction, the grounding terminal (seventh terminal) overlaps at least a part of the first terminal 131. Optionally, along the Z direction, the grounding terminal (seventh terminal) overlaps at least a part of the fifth terminal 135. Optionally, along the Z direction, the grounding terminal (seventh terminal) overlaps at least part of the fourth terminal 134 and the ninth terminal 139. Optionally, along the Z direction, the grounding terminal (seventh terminal) overlaps at least a portion of the fourth terminal 134. Optionally, along the Z direction, the grounding terminal (seventh terminal) overlaps at least a part of the ninth terminal 139. The grounding terminal (seventh terminal) is electrically connected to the memory 100 and the conductive member 140.

[0117] As shown in Figure 11, in this embodiment, the memory 100 is disposed on the rear surface 120b. On the rear surface 120b of the substrate 120, close to the right side 120d and the top surface 120e, the connector 140 (equivalent to the conduction connection of the first embodiment) component (made of a conductive material with a certain hardness) is connected to the conductive piece 140a (equivalent to the grounding terminal of the first embodiment) through soldering / butting. The conductive piece 140a is a contact prefabricated on the rear surface 120b of the substrate. The contacts are connected to the memory 100 through conductive wires provided inside the substrate 120, thereby realizing electrical connection between the connector 140 and the memory 100.Chip Variation 2:

[0118] The differences between this Variation and the chip of the Embodiment 1 include: as shown in Figures 12 and 13, the terminal group 130 on the substrate includes four communication terminals, and the four communication terminals are respectively defined as the first terminal 131 and the second terminal 132, the third terminal 133 and the fourth terminal 134, in which the first terminal 131 (data terminal) is used to send or receive data signals; the second terminal 132 (clock terminal) is used to receive a clock signal; the third terminal 133 (power supply terminal) is used to receive a power supply potential different from the ground potential (such as 3.6V / 3.3V), and provides power for the operation of the memory through this terminal; the fourth terminal 134 (reset terminal) is used to reset the internal data of the wafer or to adjust the processing device to a responsive state.

[0119] Each contact portion C1-C4 has a first projection on a first surface, wherein the first surface includes a first direction and a second direction which are orthogonal with each other; wherein the first direction is configured as the mounting direction P of mounting the ink cartridge to the printing device, in this case the first surface is parallel to the first direction (that is, the mounting direction P); or, the first direction is configured as the extension direction of the projection line of the mounting direction P of mounting the ink cartridge to the printing device on the first surface. The first surface can be inclined relative to the first direction, that is, the substrate is obliquely arranged on the ink cartridge body.

[0120] For example, the first direction in the drawing is the Z axis direction, the X axis direction is the second direction, and the second direction is perpendicular to the first direction. In this case, the first surface may be the front surface 120a or the rear surface 120b of the substrate.

[0121] The first projections of the above-mentioned contact portions on the first surface enclose a first area M. For example, the substrate includes an area Q1 and an area Q2 arranged along the center line of the substrate, and the first area M is located within the area Q1. The above - mentioned first to fourth terminals are all located within the area Q1, and the contact portions formed by each are all within the first area M. Of course, the first area is also located within the area Q1.

[0122] Furthermore, the back surface of the substrate is also provided with a grounding terminal. The grounding terminal has what can be called a fifth terminal / additional terminal, wherein the grounding terminals 135a, 135b, 135c, and 135d (equivalent to the grounding terminals of the first embodiment) are connected to the conductive member and memory, and the grounding terminal is connected to the conductive member and forms a ground point. The grounding terminals can be arranged in four positions: 135a, 135b, 135c, and 135d.

[0123] For example, the above-mentioned first to fourth terminals are all located in the area Q1. Furthermore, area Q2 can be eliminated or made as small as possible, thereby reducing the size of the chip and miniaturizing the chip, ink cartridge, and printer. When the area Q2 is canceled or is as small as possible, the area Q1 refers to the chip area where the first terminal 131 to the fourth terminal 134 are located, and the contact portion of the first terminal 131 to the fourth terminal is in the first area M.

[0124] The location of the grounding terminals 135a, 135b, 135c, 135d may be in the area Q1 on the rear surface 120b. For example, as shown in Figure 13, the position shown by the first additional terminal 135a or the second additional terminal 135b, in this case, the second projection of the ground point formed on the first surface is located in the area Q1, and the second projection and the first area M partially overlaps. Or the fifth terminal 135 may be located in the area Q1 on the front surface 120a, such as the position shown by the fourth additional terminal 135d. In this case, the second projection of the ground point formed on the first surface is located in the area Q1, that is, the second projection is located outside the first area M.

[0125] In other embodiments, the fifth terminal 135 may be located in the second area Q2 on the rear surface 120b. For example, in the position shown in the third additional terminal 135c shown in Figure 13, the second projection of the ground point formed in this case on the first surface is located outside the first area Q1, that is, the second projection is located outside the first area M. Further, in some embodiments, the width of region Q2 in the X axis direction is designed to be smaller than that of region Q1, so that the distance between the side of the second projection adjacent to the first region M and the first region can be smaller than the length of the first region.Chip Variation 3:

[0126] This Variation 3 is similar to the chip Variation 1. The difference is that, as shown in Figure 14 and Figure 64, in another implementation, in this embodiment, there are 8 terminals on the front surface 120a of the substrate. The seventh terminals 137a and 137b are disposed on the rear surface 120b of the substrate 120 as grounding terminals. The seventh terminal can also be disposed at other positions on the rear surface 120b for receiving ground potential. In addition, the seventh terminal only needs to be disposed on the rear surface 120b, and the number and shape are not limited. The chip 20 in this Variation contains two approximately rectangular seventh terminals.

[0127] The grounding terminal may be located in the area Q1, as shown in Figure 64 where the grounding terminal 137a is located; the grounding terminal may be located in the area Q2, as shown in Figure 64 where the grounding terminal 137b is located.

[0128] It should be noted that the contact pin assembly includes eight contact pins. Each contact pin contacts each terminal on the front surface and forms its own contact portion. The contact portion is represented by a dot in Figure 14. The contact area is the most likely area of contact on the terminal for the contact pin when the ink cartridge 10 is mounted on the printer.

[0129] As shown in Figure 64, the first projections formed by each contact part on the first surface enclose a first area M. The grounding terminal is connected to the conducting member to form a grounding point, and the projection of the grounding point on the first surface is the second projection. When it comes to the grounding point formed by the grounding terminal 137a, at least part of the second projection is located within the first area M and at least part is located outside the first area M. That is, the second projection at least partially overlaps with the first area M. When it comes to the grounding point formed by the grounding terminal 137b, at least part of the second projection is located within the first area M and at least part is located outside the first area M. That is, the second projection at least partially overlaps with the first area M.

[0130] As shown in Figures 7 and 15, the chip 20 has a positioning hole, and the ink cartridge body 50 is provided with a positioning post that matches the positioning hole. When the positioning hole of the chip 20 is inserted into the positioning post, the positioning of the chip 20 can be completed. The chip 20 can be further fixed on the ink cartridge body 50 by welding.

[0131] Specifically, in this embodiment, the chip 20 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are both through holes on the substrate 120, and both penetrate the front surface 120a and the rear surface 120b of the substrate 120.

[0132] The first hole 121 is a rectangular recessed portion formed from the top surface of the substrate to the bottom surface 120f, and the second hole 122 is a through hole portion located on the side 120a / 120b of the substrate 120 close to the bottom surface 120f. Correspondingly, the ink cartridge corresponding to the chip is provided with a chip mounting portion. The chip mounting portion includes a first positioning post 601 that cooperates with the first hole 121 and a second positioning post 602 that cooperates with the second hole 122. The first positioning post 601 and the second positioning post 602 are respectively combined with the first hole 121 and the second hole 122 in a plug-in manner, and then the chip 20 is fixed to the cartridge body 50 (also called the ink cartridge body 50) through thermal welding, such arrangement can prevent the chip 20 from positional deviation during the mounting process or use. Specifically, the positioning in the three directions of the X axis, Y axis, and Z axis can be achieved.

[0133] It can be understood that the number of the above positioning holes is not limited here. Specifically, only one positioning hole (for example, the first hole 121) may be disposed, or two or more positioning holes may be disposed. In addition, the shape of the positioning hole is not limited. The positioning hole can be a circular hole, a square hole, or an irregular-shaped hole. Likewise, the specific shapes and numbers of the positioning posts and restricting parts are not too limited here.

[0134] Based on the above embodiments, the ink cartridge body of the embodiment of the present application is provided with a fixing component 603 on the -Y axis side of the handle 30. The fixing assembly 603 includes a first fixing part 603a, a second fixing part 603b, and a third fixing part 603c, the third fixing part 603c restricts the connector 135 (also called a conductive member) to the ink cartridge body 50, the first fixing part 603a and the second fixing part 603b are arranged oppositely, and can clamp the connector 135 and make it bent at a right angle and in a direction away from the ink cartridge body 50.

[0135] Such an arrangement will fix the connector 135 (which can also be called a conductive member) and avoid poor contact between the connector 135 and the grounding component (not shown in the figure) on the printer due to swinging of the connector 135. Further, the connector 135 is bent at a right angle. This is beneficial for adjusting the connector 135 to extend towards the grounding component of the printer, facilitating its electrical contact with the grounding component of the printer. It prevents excessive current and reduces the probability of electric shock hazards caused by unstable grounding.

[0136] As shown in Figure 16, during the process of mounting the ink cartridge 10 with the chip 20 of this embodiment into the mounting portion 90, the first terminal 131 to the fourth terminal 134 are electrically connected to the second surface parts 911a to 914a of the corresponding first parts 911a - 914a of the first contact pin 9111 to the fourth contact pin 914 respectively.

[0137] Continuing to refer to Figures 1 and 2, when the ink cartridge 10 is mounted on the mounting portion, one end of the connector 135 is connected to the grounding terminal disposed on the rear surface 120b of the substrate, and the grounding terminal is electrically connected to the memory 100. The connector 135 extends from the rear surface 120b of the substrate, and closely extends along the ink cartridge body 50 in the +Z - axis direction. The first fixing part 603a and the second fixing part 603b act on the right - angled bent part of the connector 135, making the connector 135 turn towards the metal piece (also referred to as the grounding component) of the printer. It should be noted that the metal piece in the embodiment of the present application can be a part of the grounding component, or it is a grounding component. The metal piece is disposed in the assembly compartment of the printer, and the metal piece (can also be called as grounding component) is grounded, and there is ground signal transmission on the metal piece.

[0138] Further, the above-mentioned connector 135 is electrically connected to the grounding component of the printer and is grounded through the grounding component. With this arrangement, the electrical connection position between the grounding component and the conductive member is located above the chip, and the stability of the chip grounding is good, which improves the safety of using the chip and reduces the possibility that the printing device cannot recognize the ink cartridge. The connector 135 (conducting member) contacts and is electrically connected to the conductive wall plate 81 at the end portion 135e (shown in Figure 15). Specifically, the +X axis side end 135e (shown in Figure 15) of the connector 135 (conducting member) is in contact with the conductive wall plate 81 and is electrically connected.

[0139] In the embodiment of the present application, the mounting portion 90 can be movably mounted on the assembly compartment, and the grounding component is disposed outside the mounting portion, and part of the conductive members are disposed in the accommodation cavity of the mounting portion and are electrically connected to the grounding terminal of the chip; another part of the conductive members are disposed outside the mounting portion and is used for electrical connection with the grounding component, that is, the grounding terminal of the chip of the ink cartridge is electrically connected with the grounding component through the conductive member to realize the transmission of the ground signal.

[0140] Each chip can be adapted to the ink cartridges in the different embodiments and different implementations.

[0141] Furthermore, since the mounting portion is slidably mounted on the grounding guide rail, in order to ensure the smooth sliding of the mounting portion, the position where the conductive member contacts the grounding component in the embodiment of the present application can be configured as a ball or a ball bearing, and the ball and ball bearing serve as a part of the conductive member and are electrically connected to the conductive member. This arrangement can reduce the friction between the contact position and the conductive member, ensuring that the mounting portion and the ink cartridge slide smoothly on the grounding guide rail.

[0142] The conductive member can also be regarded as a part of the chip. When the conductive member is regarded as a part of the chip, the chip is detachably mounted on the printing device. The printing device has an assembly compartment and a mounting portion and a grounding component disposed in the assembly compartment. The mounting portion includes an accommodation cavity and a contact pin assembly, and the grounding component is located at a position other than where the contact pin assembly is located; the chip has a communication terminal group, a conductive member (also called a connector), and a memory; the communication terminal group and the contact pin assembly are electrically connected; the conductive member is electrically connected to the grounding component and the memory. The chip can also achieve the beneficial effects of this application.

[0143] It should be noted that the grounding component and the contact pin assembly are two different components. Further, the chip is disposed on the ink cartridge body, at least a part of the ink cartridge body and the chip can be located in the accommodation cavity, and the conductive member is disposed in the assembly compartment.Second implementation of the Embodiment 1:

[0144] The difference between the embodiments of this application and the previous implementation is that:

[0145] As shown in Figures 17 to 20, the grounding component provided by the embodiment of the present application includes a grounding guide rail 80, and the grounding guide rail 80 is grounded. The grounding guide rail 80 is disposed in the assembly compartment, and the mounting portion 90 is slidably disposed on the grounding guide rail 80. That is, the grounding guide rail 80 not only serves as a bearing component of the mounting portion 90, but also serves as a grounding component to transmit ground signals.

[0146] In one embodiment, a conductive wall plate 81 is disposed on one side of the grounding guide rail 80 facing the mounting portion. The conductive wall plate 81 is connected to the grounding component. The two can be an integral structure, which is not limited in the embodiment of the present application. The length extension direction of the conductive wall plate 81 is consistent with the extension direction of the grounding guide rail 80, and the conductive wall plate 81 intersects the horizontal plane. For example, the conductive wall plate 81 is perpendicular to the horizontal plane, or the conductive wall plate 81 is inclined relative to the horizontal plane.

[0147] Specifically, in this embodiment, the ink cartridge 10 also has a connector 135 (equivalent to a conductive member). The connector 135 is used to connect the chip 20 and other metal pieces on the printing device (equivalent to a grounding component) to realize the grounding function of the chip 20, that is, the connector 135 is configured as a conductive member. For example, the connector 135 includes a connection body 135bb and a conductor 135cc, where the connection body 135bb and the conductor 135cc can be provided integrally or separately, and this is not limited by the embodiment of the present application. The connector 135 can be a metal part such as copper, aluminum, or steel, or a component made of conductive silicone, conductive plastic, or the like.

[0148] One end of the connector 135 close to the chip is electrically connected to the conductive sheet 135a (equivalent to a grounding terminal). The conductive sheet 135a is disposed on the substrate 120 and is electrically connected to the memory of the chip 20. The memory needs to be grounded, and the connection mode between the conductive sheet 135a and the memory is not limited. For example, the conductive sheet 135a can be connected to the memory through a conductive wire, thereby connecting the connector 135 to the memory. The position of the conductive sheet 135a on the substrate 120 is not limited. In this embodiment, the conductive sheet 135a is disposed on the rear surface 120b of the substrate, different from other terminals of the chip 20 which are located on different surfaces of the substrate. This configuration prevents short circuits between the conductive pad 135a and other terminals, ensures stable grounding of the chip, and enhances the safety of chip operation. The conductive pad 135a (equivalent to grounding terminal) is a copper-plated layer formed on the chip 20 via processes such as electroplating.

[0149] The conductor 135cc is disposed on the ink cartridge body 50 and is in contact with other metal pieces (equivalent to grounding components) on the printer. Preferably, the conductor 135cc is arranged inside the ink cartridge body 50 to avoid contact with external objects and damage to the conductor 135cc, and to ensure the stable implementation of the grounding function of the connector 135. In this embodiment, conductor 135cc is disposed within handle 30. The connection body 135bb is used to connect the conductive sheet 135a and the conductor 135cc.

[0150] Specifically, the connection body 135bb has a first part 135b1, a second part 135b2, and a connection part 135b3. The first part 135b1 is used to connect with the conductive sheet 135a. The material of the first part 135b1 and the connection mode with the conductive sheet 135a are not limited. For example, the first part 135b1 can be made of a conductive material with a certain hardness and can be connected to the conductive sheet 135a through solder.

[0151] In some other embodiments, the connector 135 (equivalent to the conductive member) may not be provided with the conductive sheet 135a, that is, the first part 135b1 is directly connected to the memory (not shown in the figure) of the chip 20. The method of connecting the first part 135b1 to the memory is not limited. For example, the first part 135b1 may be directly connected to a conductive wire connected to the memory through soldering. The second part 135b2 is used for connection with the conductor 135cc. The connection part 135b3 is used to connect the first part 135b1 and the second part 135b2. Preferably, the connecting part 135b3 is disposed in a corresponding groove on the ink cartridge body 50 to prevent external objects from damaging the connecting part 135b3 and affecting the conductive function of the connector 135, and at the same time, it can also play a fixing role.

[0152] As shown in Figures 21 and 22, in this embodiment, the conductor 135cc is provided in the handle 30. The handle 30 has a main body portion 301, an extending portion 302, a restricting portion 303, an engaging portion 304 and a connecting portion 305. The extending portion 302, the restricting portion 303, the engaging portion 304 and the connecting portion 305 are respectively provided on the main body portion 301. The manner in which they are disposed on the main body portion 301 is not limited. For example, it can be detachable connection, fixed connection, etc.

[0153] One end of the extending portion 302 in the X axis direction is connected to the main body portion 301, and the other end is in contact with other metal pieces (equivalent to grounding components) on the printer. In this embodiment, the other end of the extending portion 302 is in contact with the conductive wall plate 81 of the printer, so that the conductor 135cc is in contact with the conductive wall plate 81 to form an electrical connection. The extending portion 302 plays a role in protecting the conductor 135cc to prevent it from being bruised, broken, misaligned, etc.

[0154] Compared with the contact area of the chip grounding terminal on the contact pin in the existing ink cartridge mounting portion, the contact area of the conductive wall plate 81 and the connector 135 in this embodiment is larger, which can ensure a stable and accurate electrical connection between the connector 135 and the grounding guide rail 80 contact to ensure the stable implementation of the grounding function of the chip 20, prevent excessive current, and reduce the probability of electric shock hazard caused by unstable grounding.

[0155] On the basis of the above embodiments, the extending portion 302 in the embodiment of the present application is also provided with a color identification portion 302a for indicating the color of the ink stored in the ink cartridge. The ink color indication method of the color recognition portion 302a is not limited. For example, the ink color stored in the ink cartridge may be indicated by color, pattern, text, and combination thereof.

[0156] The restricting portion 303 cooperates with the restricting protrusion 502 provided on the ink cartridge to restrict the movable range of the handle 30 in the X axis direction. The position and shape of the limiting protrusion 502 on the ink cartridge body 50 is not limited. For example, the limiting protrusion 502 can be a cylinder, a cone, an irregular-shaped protrusion, etc. In this embodiment, the limiting protrusion 502 is a cylinder.

[0157] The engaging portion 304 cooperates with the fixing portion 90d provided on the mounting portion 90 to fix the ink cartridge 10 to the mounting portion 90 and prevent the ink cartridge 10 from being detached from the mounting portion 90. The connection portion 305 is used to connect the handle 30 to the ink cartridge body 50. The connection method between the connection portion 305 and the ink cartridge body 50 is not limited. For example, it may be a detachable connection, a fixed connection, etc. In some other embodiments, the handle 30 may not be provided with the connecting portion 305, and the main body portion 301 is directly connected to the ink cartridge body 50.

[0158] When the ink cartridge 10 is mounted on the mounting portion, one end of the connector 135 is a conductive sheet 135a, which is connected to the memory on the ink cartridge chip 20 to receive the current output from the chip 20. The conductive sheet 135a transfers the received current to the conductor 135cc through the connection body 135bb. The other end of the connector 135 is a conductor 135cc, which is connected to other metal pieces on the printer, and the current received from the connection body 135bb is transferred to other metal pieces on the printer to realize the chip grounding function.

[0159] Specifically, the conductor 135cc is disposed through the handle 30, and the conductor 135cc is disposed through the main body part 301, the extending portion 302 and the connecting portion 305 of the handle 30. Since the engaging portion 304 disposed on the handle main body portion 301 cooperates with the fixing portion 90d provided on the mounting portion 90 for fixing the ink cartridge 10 to the mounting portion 90, the conductor 135cc is disposed through the handle 30 and connected with the handle 30. The conductor 135cc positioned in close proximity to the engaging portion 304 within the handle 30 can ensure stable and accurate contact between the connector 135 and other metal pieces on the printer, ensure the stable implementation of the grounding function of the chip 20, prevent excessive current, and reduce the probability of electric shock caused by unstable grounding. It ensures good grounding stability of the chip, improves the safety of using the chip, and reduces the possibility that the printing device cannot recognize the ink cartridge.Third implementation of the Embodiment 1:

[0160] Figures 23 to 26 are schematic diagrams related to the third implementation of the Embodiment 1 of the present application. The differences between this implementation and the second implementation include: as shown in Figures 23 to 26, Figure 23 is a schematic diagram of the ink cartridge 10 mounted on the mounting portion 90, the grounding component has a grounding guide rail, and the grounding guide rail has a conductive wall plate 81. The conductive member 105 is in contact with the conductive wall plate 81 and transmits a ground signal. A baffle 84 is disposed in the +Z axis direction of the conductive wall plate 81.

[0161] Typically, the baffle 84 is made of plastic and non-conductive material. In the direction of the X axis, the end of the baffle 84 is closer to the mounting portion 90 than the end of the conductive wall plate 81 (that is, the end of the baffle 841 is located on the +Z axis and -X axis sides than the conductive wall plate 81), therefore when the ink cartridge 10 is mounted onto the printing device, the conductive member 105 needs to cross the baffle 841 before it can contact the conductive wall plate 81.

[0162] One end of the conductive member 105 in this implementation is in contact with the grounding terminal 135a on the chip 20, and the other end is in contact with the conductive wall plate 81 of the grounding component. The transmission path of the ground signal is in sequence: the memory of the chip 20, the grounding terminal 135a, the conductive member 105, and the conductive wall plate 81 of the grounding component.

[0163] The handle 30 has a main body portion 301, an extending portion 302, an engaging portion 304, a first gap 308, and a second gap 309. The ink cartridge is also provided with a fixing portion 307 for fixing the conductive member 105. The extending portion 302 includes a flat extending portion 3025, a first bending portion 3021, a second bending portion 3022, an abutment accommodation cavity 3023, and a fixing opening 3024. The purpose of providing the extending portion 302 is to fix the conductive member 105 so that the conductive member 105 crosses the baffle 84 and the conductive member 105 abuts the conductive wall plate 81. The flat extending portion 3025 extends toward the +X axis direction for the purpose of better abutting the conductive member 105 against the conductive wall plate 81.

[0164] The first bending portion 3021 extends from the flat extending portion 3025. The first bending portion 3021 extends toward the +X axis (the direction where the conductive wall plate 81 is located) and the +Z axis direction (upper); the second bending portion 3022 extends from the first bending portion 3021, and the second bending portion 3022 faces the -X axis (the direction away from the conductive wall plate 81 / the direction towards the cartridge) and the +Z axis direction (upper). This structural design is to guide the extending portion 302 and the conductive member 105 over the baffle 84 when the ink cartridge 10 is mounted onto the printing device, and when the ink cartridge 10 is taken out from the printing device, the second bending portion 3022 can guide the deformation / compression of the handle 30 to facilitate the removal of the ink cartridge 10.

[0165] The abutting accommodation cavity 3023 is used to accommodate the abutting portion 1057 of the conductive member 105, and the abutting portion 1057 is used to abut the conductive member 105 against the conductive wall plate 81. The abutting accommodation cavity 3023 is relatively a recessed portion, which can protect the abutting portion 1057 to a certain extent and reduce damage to the abutting portion 1057. The abutting accommodation cavity 3023 is disposed at the intersection of the first bending portion 3021 and the second bending portion 3022, so that the abutting portion 1057 is located at the position closest to the +X axis to facilitate the conductive component 105 abutting against the conductive wall plate 81.

[0166] Further, the fixing opening 3024 cooperates with the elastic portion 1056 so that the conductive member 105 is firmly fixed on the ink cartridge 10 to prevent the conductive member 105 from being separated from the ink cartridge 10. The handle 30 extends from the ink cartridge body 50 and has a certain degree of elasticity. It can shrink toward the -X axis direction and can restore to its original position. The extending portion 302 is located on the handle 30 and has a certain degree of elasticity, and it can move in the -X axis direction, allowing the conductive component 105 to cross the baffle 84, when the handle 30 is compressed, the extending portion 302 tends to move toward the +X axis, generating a pressing force on the abutting portion 1057. This ensures more stable abutment between the abutting portion 1057 and the conductive wall plate 81. The abutting portion 1057 is disposed at the intersection of the first bending portion 3021 and the second bending portion 3022.

[0167] The conductive member 105 includes a first part 1051a, a second part 1051b, and a third part 1051c. The first part 1051a is fixed on the ink cartridge body 50. Specifically, through the cooperation of the through hole 1053 and the fixing portion 307, the conductive member 105 is prevented from being separated from the ink cartridge body 50. The through hole 1053 and the fixing portion 307 may be tightly fixed.

[0168] Optionally, after the through hole 1053 is matched with the fixing portion 307, the part of the through hole 1053 protruding from the fixing portion 307 can be laid on the first part 1051a by welding and hot melting to prevent the conductive member 105 from being separated from the ink cartridge body 50. The second part 1051b is adapted to the main body portion 301 of the handle 30. A first gap 308 is provided on the -X axis direction side of the engaging portion 304 and the +X axis direction side of the main body portion 301. The first gap 308 accommodates a part of the second part 1051b. The third part 1051c fits the shape of the extending portion 302, allowing the conductive member 105 to better abut against the conductive wall plate 81.

[0169] The third part 1051c has an abutting portion 1057 and an elastic portion 1056. The abutting portion 1057 is disposed in the abutment accommodation cavity 3023. The elastic portion 1056 is an elastic sheet member extending from the conductive member 105 and can cooperate with the fixing opening 3024 so that the conductive member 105 is fixed on the handle 30. The conductive member 105 has a first bending area AA extending toward the conductive wall plate 41 and a second bending area BB connected to the first bending area AA and extending toward the upward direction (+Z axis direction). The position where the conductive member 105 contacts the conductive wall plate 81 is located on the second bending area BB, that is, the abutting portion 1057 is located on the second bending area BB.

[0170] The first bending area AA is consistent with the direction of the first bending portion 3021 of the extending portion 302. The first bending area AA extends toward the +X axis (the direction where the conductive wall plate 81 is located) and the +Z axis direction (upper). The second bending area BB is a part accommodated in the abutting accommodation cavity 3023, and the second bending area BB is connected to the first bending area AA and extends toward the upward direction (+Z axis direction). This structure facilitates the abutment between the conductive component 105 and the conductive wall plate 81. The abutting portion 1057 is a protrusion on the second bending area BB, and the abutting portion 1057 can be an arc-shaped, spherical, line-shaped, or point-shaped protrusion. Preferably, the abutting portion 1057 is a spherical protrusion (as shown in Figure 26), it facilitates the abutment against the conductive wall plate 81 and can reduce the friction between the abutting portion 1057 and the conductive wall plate 81 as the ink cartridge 10 slides with the mounting portion 90, ensuring that the ink cartridge 10 slides smoothly during the sliding process.

[0171] Since the handle 30 is elastic, it can contract and return to its original state. The handle 30 is different in its natural state and in the state mounted on the printing device. The conductive member 105 also has two states: an initial state and an abutment state. The conductive member 105 can be switched between the initial state and the abutment state. The conductive member 105 is farther away from the ink cartridge body 50 in the initial state than in the abutment state. The abutting portion 1057 is further away from the ink cartridge body 50 in the initial state than in the abutment state. After the ink cartridge 10 is mounted on the printing device, the abutting portion 1057 of the conductive member 105 exerts a pressing force on the conductive wall plate 81, which can make the abutting portion 1057 better abuts against the conductive wall plate 81.

[0172] It should be noted that the conductive member 105 is made of conductive material, such as metal, conductive silica gel, conductive plastic, etc. Optionally, the conductive member 105 is made of metal and bent into a structure as shown in Figures 23-25. The abutting portion 1057 can be made by hot pressing, and a spherical protrusion is formed by hot pressing the originally flat metal plate surface; the elastic portion 1056 can be made by stamping, and one end of the elastic portion 1056 is punched to form a suspended elastic portion 1056; the through hole 1053 can be made by stamping, and is punched into a through hole.Fourth implementation of the Embodiment 1:

[0173] Fig. 27 is a schematic diagram of the fourth embodiment. The description of the ink cartridge in this embodiment is consistent with the content of the Embodiment 1. The chip used is the Variation 1 of the chip or the Variation 3 of the chip, which will not be described again here.Embodiment 2

[0174] It should be noted that the insertion method of the mounting portion and the ink cartridge in this embodiment is different from that in the Embodiment 1, and the structure of the mounting portion of the printer is also different. The mounting portion 90 in the Embodiment 2 is fixed in the assembly compartment, and the grounding component is provided in the containing cavity.

[0175] The ink cartridge in the Embodiment 2 can be adapted to several types of ink cartridges in the Embodiment 1. The difference between the Embodiment 2 and the Embodiment 1 is that an antenna-type conductive member is provided in the Embodiment 2, and at least part of the cavity wall forming the mounting cavity is configured as a grounding component, and one end of the conductive member is electrically connected to the grounding terminal of the chip. The other end is electrically connected to at least part of the top wall of the mounting cavity, and the electrical connection point between the two is located above the chip.

[0176] On the basis of the above embodiment, in this embodiment, the conductive sheet 135a in the conductive member can be eliminated, the connector 135 can be directly connected to the conductive wire through solder, and the position of the positioning hole provided on the chip is also different from the above embodiment.

[0177] As shown in Figures 28 to 31, in this embodiment, the chip 20 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are both through holes on the substrate 120, and both penetrate the front surface 120a and the rear surface 120b of the substrate 120. The first hole 121 is a semicircular recessed portion formed from the left side 120c to the right side 120d, and the second hole 122 is a semicircular recessed portion formed from the right side 120d to the left side 120c.

[0178] Correspondingly, the ink cartridge is provided with a chip mounting portion. The chip mounting portion includes a first positioning post 601 and a second positioning post 602. The first positioning post 601 and the second positioning post 602 protrude from the first hole 121 and the second hole 122 respectively, and then fix the chip 20 to the ink cartridge body 50 by welding with a thermal welding head. Such arrangement can prevent the chip 20 from shifting along its position during the mounting process or during use after mounting.

[0179] As shown in Figures 30 and 31, when the consumable cartridge 10 is mounted on the mounting portion 90, one end of the connector 135 is connected to the grounding terminal 135a of the memory100 / rear surface 120b provided on the rear surface 120b of the substrate. The connector 135 extends out from the substrate rear surface 120b and fits the cartridge body 50 (ink cartridge body 50) along the direction away from the chip 20, until it is close to the end side of the connector 135, and the connector 135 is bent in a direction away from the surface of the box body 50. Thus, it is connected to the metal piece 96 (equivalent to the grounding component of the first embodiment) on the printing device. The beneficial effects of this design are: the stability of the chip grounding is good, and the safety of using the chip is improved.

[0180] When the ink cartridge 10 is mounted on the mounting portion 90, the connector 135 connected to the memory 100 extends along (or abut against) the rear surface 120b of the chip 20 and extends to the top surface of the ink cartridge 10. It then protrudes from the upper end of the chip 20 through the top surface of the ink cartridge 10 into a gap in the mounting portion, with the end of the connector 135 being bent at a right angle. The end 135e of the connector 135 (the end farthest from the cartridge body) abuts against a metal piece 96 (equivalent to the grounding component in the Embodiment 1).

[0181] The connector 135 (the conductive member of the Embodiment 1) is bent in a direction away from the surface of the ink cartridge body 50 and toward the metal piece 96 of the printer (the cavity housing the ink cartridge 10). The metal piece 96 is the first side wall 90c of the mounting portion in the embodiment, that is, the cavity wall that at least partially forms the accommodation cavity is configured as a grounding component, and the electrical connection position between the grounding component and the conductive member is located above the chip. With this arrangement, the stability of the chip grounding is good, which improves the safety of using the chip.

[0182] One end of the connector 135 is connected to the rear surface 120b of the substrate 120, and the other end is connected to the metal piece 96 of the printing device. The metal piece 96 of the printing device is not limited and can be any metal on the printing device that can be contacted by the connector 135.Embodiment 3:

[0183] It should be noted that the mounting method of the mounting portion and the ink cartridge in this embodiment is different from that in the Embodiment 1, and the structure of the mounting portion of the printer is also different. The mounting portion 90 of the Embodiment 2 is fixed in the assembly compartment, and the grounding component is disposed in the accommodation cavity.

[0184] This embodiment provides another antenna-type conductive member, and at least part of the cavity wall forming the mounting cavity is configured as a grounding component. One end of the conductive member is electrically connected to the grounding terminal of the chip, and the other end is electrically connected to at least part of the cavity wall of the mounting cavity.First implementation of Embodiment 3:

[0185] As shown in Figure 32, the front surface 120a of the chip 20 is provided with the first terminal 131 - the fourth terminal 134, and the position arrangement of their respective contact portions C, the memory 100, the connector 135, and the second positioning hole 122 of the substrate are the same as the Embodiment 2, and it will not be described in detail here.

[0186] The connector 135 (equivalent to the conductive member in the first embodiment) connected to the memory 100 extends along (or abut against) the rear surface 120b of the chip 20 and extends to the top surface of the ink cartridge 10, and then along the ink cartridge 10 extends out from the upper end of the chip 20 and the top surface of the ink cartridge 10, and enters the gap of the mounting portion. The end 135e of the connector 135 (the end far away from the ink cartridge body) abuts against the grounding component. The extended portion of the connecting belt 135 (which can be called the connector 135) (equivalent to the conductive member of the first embodiment) is bent in a direction away from the surface of the cartridge body 50 and toward the metal piece (equivalent to the grounding components of the first embodiment) of the printing device (the cavity housing the ink cartridge 10), thereby achieving electrical connection with the metal pieces of the printing device.Second implementation of Embodiment 3:

[0187] In a second implementation, another antenna-type conductive member is provided in this embodiment, and at least part of the cavity wall forming the mounting cavity is configured as a grounding component, and one end of the conductive member is electrically connected to the grounding terminal of the chip, the other end is electrically connected to at least part of the cavity wall of the mounting cavity.

[0188] The mounting method of the mounting portion and the ink cartridge in this embodiment is different from that in the Embodiment 1, and the structure of the mounting portion of the printer is also different. Therefore, the direction represented by the three-dimensional coordinate system in this embodiment is also different from that in the Embodiment 1. The mounting portion 90 of the Embodiment 2 is fixed in the assembly compartment, and the grounding component is arranged in the accommodation cavity.

[0189] As shown in Figure 33, the printer in this embodiment includes: a printing unit 4 and a base 5. The base 5 includes a bracket and one or more mounting portions 90.

[0190] Further, one mounting portion 90 can hold one ink cartridge 10. When the number of mounting portions 90 is four (as shown in Figure 33), the four ink cartridges 10 can store four different colors of ink, such as black, yellow, blue red. For another example, when six ink cartridges 10 can be carried in the base 5, the number of mounting portions 90 is six, and the six ink cartridges 10 respectively store black, yellow, blue, red, light blue, and light red inks. Furthermore, ink of the same color (e.g., black) can be accommodated in a plurality of mounting portions 90.

[0191] The ink cartridge 10 is first mounted onto the tray 97 along the first direction D1, and then the combination of the ink cartridge 10 and the tray 97 is mounted onto the mounting portion 90 along the second direction D2. When the printer prints, the base 5 provides ink for the printing work of the printing unit 4 to ensure the normal printing work of the printing unit 4. When the printer is placed in its natural state, the printing unit 4 is directly above the base 5.

[0192] In the three-dimensional rectangular XYZ axis coordinate system shown in Figure 33, the X axis, Y axis, and Z axis are perpendicular to each other. When the printer is placed in its natural state, the direction of gravity is the +Z direction, the mounting direction D2 (second direction D2) of the ink cartridge 10 in the mounting portion 90 is the +Y direction, and the arrangement direction of the mounting portion 90 is the +X direction. The first direction D1 is the +Z direction. When the ink cartridge 10 needs to be mounted onto the mounting portion 90, the ink cartridge 10 is first mounted on the tray 97 along the first direction D1; then the combination of the ink cartridge 10 and the tray 97 is mounted onto the mounting portion 90 along the mounting direction D2.

[0193] As shown in Figure 34, this structure is a part mounted on the +Y direction of the base 5. When the ink cartridge 10 (it can also be an assembly) is mounted onto the mounting portion 90 along the mounting direction D2, the front end side of the ink cartridge 10 in the +Y direction is in contact with the structure shown in Figure 34, thereby ensuring that the ink cartridge 10 (can also be an assembly) and the mounting portion 90 are combined in place.

[0194] The internal structure of the mounting portion 90 includes a fixed frame, and the fixed frame is provided with a contact pin assembly 91, an ink supply portion 92 (ink filling tube), columnar positioning portions 93f, 93s and a locking portion 94. The locking portion 94 is a rod-shaped component that can reset and swing, that is, the locking portion 94 is configured as a conductive swing rod of the present application. The rod-shaped component is provided with a protrusion extending in the -Z axis direction at the movable end. The protrusion is used to cooperate with the groove at the bottom of the tray 97 to fix the assembly of the ink cartridge 10 and the tray 97.

[0195] The contact pin assembly 91 can be electrically connected to the chip on the ink cartridge 10 when the assembly is mounted on the mounting portion 90. The contact pin assembly 91 includes a plurality of contact pins (not marked in the figure) made of elastic conductive steel sheets. The contact pin assembly 91 is arranged in the mounting portion 90 in an inclined manner. The specific structure of the contact pin assembly 91 will not be described again. The structure of the contact pin assembly 91 can be seen in Figure 4. Specifically, the above-mentioned assembly is mounted or removed along the +Y and -Y directions in the figure. This assembly is physically engaged with the mounting portion 90 through the housing, and is electrically connected to the contact pin assembly 91 through the chip located on the ink cartridge.

[0196] As shown in Figures 35-38, the ink cartridge 10 includes: a chip 20, a connector 60, an ink supply head 40 and an ink bag 10a, wherein the chip 20 is disposed on the front end side of the ink cartridge 10 in the mounting direction D2, and the connector 60 is configured as c conductive member. The connector 60 is made of conductive material, and a part of the connector 60 is connected to the chip 20 and the other part is connected to the grounding component.

[0197] An ink outlet 41 is provided on the +Y axis side of the ink supply head 40. Ink is stored in the ink bag 10a. The ink outlet 41 is in liquid communication with the inside of the ink bag 10a. The ink reaches the ink filling tube 92 through the ink outlet 41, and then the ink filling tube 92 can supply ink to the print head, so that the print head can be used to perform printing actions.

[0198] After adopting the above technical solution, the ground signal is transmitted to the chip 20 through the metal pieces and conductive members, which improves the stability and reduces the situation that the ground cannot be connected or the grounding is unstable. The grounding terminal is no longer provided on the substrate. By using connectors, the grounding stability of the chip is improved, preventing excessive current, and reducing the probability of electric shock caused by the grounding terminal on the chip being unable to make stable contact with the contact pins on the printer, which helps to improve the safety of using the chip and reduces the possibility that the printing device cannot recognize the ink cartridge.

[0199] In the above solution, the metal piece of the mounting portion 90 (equivalent to the grounding component of the Embodiment 1) may be the outer frame of the mounting portion 90 (+Z axis, -Z axis, +X axis, -X axis, +Y axis direction) or part of the outer frame. For the safety of the user, the metal pieces of the mounting portion 90 are all grounded, and the ground signals with the printer are connected. Preferably, in this implementation, the other part of the connector 60 (equivalent to the conductive member of the Embodiment 1) is connected to a part of the metal piece 96 in the -Z axis direction of the mounting portion 90, that is, at least part of the accommodation cavity wall forms the grounding component. As shown in Figure 33, the metal piece 96 is disposed in the -Z axis direction of the base 5 and is connected to the ground signal of the metal piece 96 (equivalent to the grounding component of the first embodiment) and the printer 1.

[0200] As shown in Figures 35 and 36, the chip 20 provided in this embodiment has a memory 100, a substrate 120, and a plurality of terminals 130. The substrate 120 has a front surface 120a, a rear surface 120b, a left surface 120c, a right surface 120d, a top surface 120e, and a bottom surface 120f. The front surface 120a and the rear surface 120b are arranged oppositely; the left surface 120c and the right surface 120d are arranged oppositely; the top surface 120e and the bottom surface 120f are arranged oppositely.

[0201] Further, the chip 20 has a first hole 121, a second hole 122, a third hole 123 and a fourth hole 124. The first hole 121, the second hole 122, the third hole 123 and the fourth hole 124 are all through holes on the substrate 120, and all penetrate the front surface 120a and the rear surface 120b of the substrate 120.

[0202] The first hole 121 is a recessed portion formed from the top surface 120e to the bottom surface 120f, and the second hole 122 is a recessed portion formed from the bottom surface 120f to the top surface 120e. The third hole 123 is a recessed portion formed from the left surface 120c to the right surface 120d, and the fourth hole 124 is a recessed portion formed from the right surface 120d to the left surface 120c.

[0203] With this arrangement, the ink cartridge 10 capable of mounting the chip 20 of this embodiment is provided with a chip mounting portion. The chip mounting portion includes a plurality of positioning posts. The plurality of positioning posts are respectively combined with the first hole 121, the second hole 122, and the third hole 123 and the fourth hole 124 in a protruding manner, and then the chip 20 is fixed to the ink supply head 40 through thermal welding to prevent the chip 20 from shifting along the Y axis or Z axis during mounting process or use process after mounting.

[0204] Similar to the above-mentioned first implementation, the terminals 131-134 provided on the front surface in this implementation are all communication terminals. The purpose and layout of each communication terminal on the front surface are the same as those in the first implementation. No further details will be given.

[0205] The connector 60 (equivalent to the conductive member in the Embodiment 1) and the memory 100 may also be connected through the fifth terminal / additional terminal 135a (equivalent to the grounding terminal in the Embodiment 1) and its wire. It can be understood that in this implementation, the fifth terminal 135a may not be provided, but the connector 60 is directly connected to the memory 100. Preferably, using the fifth terminal 135a makes the connection between the connector 60 and the memory 100 more effective and the contact more stable.

[0206] Further, the conductive member and the fifth terminal / additional terminal 135a may be connected by soldering and fixing. Each terminal 130 has a contact portion, which are respectively a first contact portion to a fourth contact portion. The contact area is the most likely contact area of the contact pin on terminal 130 when the cartridge is mounted on the printer.

[0207] In the embodiment of the present application, the connector 60 is used as a conductive member. The connector 60 is made of conductive material. The ground signal of the printer is connected to the memory through the conductive member and the fifth terminal / additional terminal (equivalent to the grounding terminal), so that the chip of the ink cartridge and the grounding component are grounded together.

[0208] As shown in Figures 37 to 42, the connector 60 includes a first part 60a and a second part 60b. The first part 60a is used to connect the second part 60b and the fifth terminal / additional terminal 135a of the chip 20; the second part 60b is used to connect the metal piece 96 and the first part 60a.

[0209] The chip 20 is connected to the first part 60a. When the ink cartridge is mounted on the mounting portion 90, each communication terminal of the chip 20 is connected to the first contact pin 911 to the fourth contact pin 914 on the contact pin assembly 52 respectively. The shapes of the first part 60a and the second part 60b are not limited, and they may be set in a regular shape, such as a rectangle, or in a zigzag or other irregular shape. In addition, the first part 60a can be formed in one piece, or can be formed by splicing several sections of metal sheets.

[0210] Furthermore, the connector 60 may also be an integral structure without the first part 60a and the second part 60b. When the conductive member includes the first part 60a and the second part 60b, the structure of the first part 60a is simplified, and the second part 60b can be manufactured into a more complex structure.

[0211] For example, the second part 60b can also be used as the handle 30 of the ink cartridge. When the ink cartridge is mounted on the tray 97, it plays the role of a handle during the mounting and removal process, so as to facilitate the user to mount and remove the ink cartridge. Such an arrangement can not only complete the transmission of the ground signal, but also achieve the effect of simplifying the structure of the ink cartridge (reducing the production, manufacturing, and assembly of parts of the handle). Therefore, this structure can reduce the number of parts, simplify part of the structure of the ink cartridge, and reduce costs.

[0212] Further, the first part 60a of the connector 60 has: a first connection portion 60aa and a second connection portion 60ab. The first connection portion 60aa is used to connect to the fifth terminal or the additional terminal 135 of the chip 20; the second connection portion 60ab is used to connect to the second part 60b.

[0213] The second part 60b has a first connection portion 60ba and a second connection portion 60bb. The second connection portion 60bb is used to connect with the second connection portion 60ab; the first connection portion 60ba is used to abut against the metal piece 96.

[0214] Specifically, the first connection portion 60ba abuts against the +Z axis surface of the metal piece 96 to complete the transmission of the ground signal. The first connection portion 60ba is not necessarily at the end of the second part 60b; as shown in Figures 41-42, the first connection portion 60ba is provided at the middle position of the second part 60b. The first connection portion 60ba may be a combination of one or more positions.

[0215] As shown in Figure 41, the first connection portion 60ba can be in three different positions. Because the second part 60b not only needs to abut against the metal piece 96, but also needs to function as a handle, therefore, in the Z axis direction, the first connection portion 60ba is on the -Z axis direction side of the second part 60b. In the Z axis direction, the first connection portion 60ba is located on the -Z axis direction side of the second connection portion 60bb; the second part 60b is located on the -Z axis direction side of the first part 60a; the first part 60a is located on the -Z axis direction of the chip 20 side. That is, the part abutting against the metal piece 96 is located at the uppermost position.

[0216] In the Y axis direction, the first connection portion 60ba is located on the -Y axis direction side of the second connection portion 60bb; the second part 60b is located on the -Y axis direction side of the first part 60a; the first part 60a is located on the -Y axis direction of the chip 20 side. That is, the first connection portion 60ba is located on the -Z axis and -Y axis direction sides of the second connection portion 60bb; the second part 60b is located on the -Z axis and -Y axis direction sides of the first part 60a; the first part 60a is located on the -Z axis, -Y axis direction sides of the chip 20.

[0217] It should be noted that the metal piece 96 contacted by the second part 60b can be a conductive metal piece anywhere in the printer. Preferably, along the Z axis direction, the position of the metal piece 96 that the second part 60 b contacts is located at the top of the ink cartridge 10.

[0218] In addition, continuing to refer to Figures 34 and 37, when the ink cartridge is mounted on the mounting portion 90, the columnar positioning portions 53f, 53s cooperate with the positioning holes 97a and 97b on the tray 97 and the holes 42a and 42b on the ink cartridge to restrict the position of the assembly on the mounting portion; the ink filling tube 92 (equivalent to the ink supply portion 92 of the Embodiment 1) matches the ink outlet 41 and can provide ink for the printer to print; the contact pin assembly 91 is in contact with the chip 20, providing chip signal transmission.

[0219] The protrusions on the locking portion 94 are used to cooperate with the grooves on the bottom of the tray 97 to fix the assembly of the ink cartridge and the tray 97. The connector 60 is in contact with the metal piece 96 to transmit the ground signal. When the ink cartridge is mounted on the tray 97, the connector 60 serves as a handle during the mounting and removal of the ink cartridge, making it convenient for the user to mount and remove the ink cartridge.

[0220] It should be noted that the number and shape of the positioning holes 97a / 97b on the tray 97 and the holes 42a / 42b on the ink cartridge are not limited. For example, one or more positioning holes can be provided, and the shape can be set into a circle, a square or other irregular shapes, so as to achieve stable cooperation with the printer and stable mounting of the ink cartridge.

[0221] Further, continuing to refer to Figures 37 to 40, the ink cartridge in this implementation has an ink supply head 40 and an ink bag 10 storing ink inside. Among them, the chip 20 and the connector 60 are both arranged on the ink supply head 40. The ink supply head 40 is equipped with an ink outlet 41 on its +X side. This ink outlet 41 is connected to the ink bag 10a via an internal flow channel within the head, allowing the ink stored in the ink bag 10a to be supplied to the printer through the ink outlet 41.

[0222] Referring to Figure 40, an axis hole is provided on the +Z axis side of the ink supply head 40, and the axis of the second part 60b is mounted on cooperation with the axis hole. The ink supply head 40 is also provided with a support part 102 on the +Z axis side, which is located on the +Z axis side of the second part 60b and the -Y axis side of the axis hole, and supports at least a part of the second part 60b.

[0223] Specifically, in this embodiment, the support part 102 is a protrusion extending from the upper surface of the ink supply head 40 in the +Z axis direction, and along the +Z axis direction, the support part 102 is higher than the above-mentioned axis. When the ink cartridge is mounted, at least part of the second part 60b is in contact with the support part 102 and is located on the +Z axis side of the support part 102.

[0224] Therefore, in the mounted state, the second part 60b is tilted toward the -Y axis side and the -Z axis side due to the action of the support part 102, and the -Z axis end of the second part 60b is in contact with the metal piece 96 above the ink cartridge, and the electrical connection is realized, so that the first connection portion 60ba is located on the -Z axis and -Y axis direction sides of the second connection portion 60bb; the second part 60b is located on the -Z axis and -Y axis direction sides of the first part 60a.

[0225] This setting not only reduces the risk of electric shock caused by unstable grounding, but also makes the chip grounding more stable and improves the safety of chip use. At the same time, it is also convenient for users to mount and remove ink cartridges.

[0226] It should be noted that the number and shape of the supporting part 102 are not limited. Specifically, the supporting part 102 may be set as one, two or more, and may be provided with a rectangular parallelepiped, a cylinder, a triangular prism or other regular or irregular shapes. The shape is sufficient as long as it can support the second part 60b and achieve stable contact with the metal piece 96.

[0227] Preferably, along the X axis direction, the contact area between the second part 60b and the metal piece 96 is closer to the left surface 120c of the chip substrate 120 than to the right surface 120d of the chip substrate 120. Preferably, the contact area between the second part 60b and the metal piece 96 may not be disposed on the first connection portion 60ba as shown in Figure 41, but may be disposed within the area of the first area R1.

[0228] As shown in Figure 41, the part connecting the second part 60b and the metal piece 96 is: the third connection portion 60bc. The third connection portion 60bc is located in the first region R1, and in the X axis direction, the second part 60b is tilted (this tilting method can be realized by the different heights of the plurality of support part 102), and the connection portion 60bc is located at the end of the +Z axis of the second part.

[0229] It should be noted that during the process of mounting the ink cartridge 10 to the printing device, the connector 60 (conductive member) contacts the grounding component first, and the chip 20 contacts the contact pin assembly 91 later.Third implementation of the Embodiment 3:

[0230] In the third implementation, based on the above-mentioned second implementation, this implementation provides a new conductive member. One end of the conductive member is electrically connected to the grounding terminal of the chip, and the other end is electrically connected to at least part of the cavity walls of the mounting cavity, and the electrical connection position of the two is located above the chip.

[0231] As shown in Figures 43 and 44, the chip provided in this implementation is different from the above-mentioned the third implementation in that the chip 20 is provided with a recess 21. The function of the recess 21 is to avoid the fifth contact pin 915 and prevent the fifth contact pin 915 from abutting or contacting the chip 20; that is, when the ink cartridge 10 is mounted on the mounting portion of the printer, a part of the fifth contact pin 915 is located inside the recess 21, the fifth contact pin 915 does not abut or contact the chip 20.

[0232] It should be noted that the chip 20 does not need to have the recess 21, as long as there is no terminal / contact portion that can be connected to the fifth contact pin 915 in the X axis direction of the chip, even if the chip 20 abuts against the fifth contact pin 915, there will be no electrical connection between the two, nor the transmission of ground signals.

[0233] As shown in Figures 45 to 51, the ink cartridge 10 includes: a chip 20, a connector 70 (equivalent to the conductive member of the Embodiment 1), an ink supply head (also called a base) 40 and an ink bag 10a; the chip 20 is disposed on the front end side of the ink cartridge 10 in the mounting direction D2; the connector 70 is configured as a conductive member, and its material is a conductive material. A part of the connector 70 is connected to the chip 20, and the other part is connected to the metal piece 96 (equivalent to on the grounding component of the Embodiment 1) of the mounting portion 90. For example, the connector 70 connects the lower surface 96a of the metal member 96 in the +Z axis direction, that is, the connector 70 connects the lower surface 96a of the metal piece 96 (equivalent to the grounding component of the Embodiment 1) facing the mounting portion 90.

[0234] The ground signal between the chip 20 and the printer is transmitted through the connector 70 and the metal piece 96. After adopting the above technical solution, the ground signal is transmitted to the chip 20 through the metal piece 96 and the connector 70, which improves the stability and reduces the situation where the ground cannot be connected or the grounding is unstable.

[0235] Further, in this embodiment, the first terminal 131 to the fourth terminal 134 are provided on the front surface 120a of the chip 20, and the fifth terminal 135 is provided on the rear surface 120b of the chip 20. A plurality of terminals 130 (first terminal 131 - fifth terminal 135 ) are provided in the first region R1 on the -X axis of the chip 20. The first region R1 is located on the -X axis side of the chip, so that the terminals on the chip 20 are compactly arranged, and the fifth terminal 135 that transmits the ground signal and the communication terminal (the first terminal 131- the four terminals 134) that transmits the signal with a high level are distributed on different surfaces of the chip 20, thereby reducing the possibility of short circuit between them and avoiding mutual electromagnetic interference.

[0236] The difference from the third implementation mentioned above is that, as shown in Figures 45 and 46, the connector 70 provided in this implementation is an integrally formed member. The material can be a metal profile made of low carbon steel or high carbon steel, and the surface can be plated with nickel or chromium to prevent rust; the raw material can also be a metal profile made of stainless steel.

[0237] The cross section of the connector 70 may be circular, elliptical, rectangular, square, trapezoidal or other shapes. The production process can be hot forming or cold forming. For example, a spring machine is used to produce a conductive member as shown in Figure 45 by using a spring machine to produce a metal wire with a diameter of 0.6mm from 82B high carbon steel with a nickel plated surface through a thermal deformation process. This implementation does not impose any restrictions on the raw materials, profiles, production processes, etc. of the conductive member, as long as stable transmission of the ground signal can be ensured.

[0238] For example, if the cross-section of the profile is circular, it can be a metal wire with a diameter of 0.3-2.5mm. Preferably, the conductive member is a metal wire of the diameter of 0.5-1.0mm, and the elasticity and shape stability of the metal wire are required. If the cross-sectional diameter of the metal wire is small, it may not be able to maintain the original shape stably, causing the ink cartridge to be unable to maintain its original shape after being mounted more than 10 times, thus affecting the smooth transmission of the ground signal. If the diameter of the metal wire is larger, it may cause jamming during the mounting or removal of the ink cartridge 10.

[0239] If the metal wire is non-circular, metal profiles with a width of 0.3-2.5mm can be selected. Preferably, the conductive member adopts metal profiles with a width of 0.5-1.0mm. For circular, elliptical profiles (with arc-shaped main surfaces such as round / oval diameters), a contact surface shall be ground at the position of part 704 (as shown by the dotted line in Figure 45), transforming the connecting part with the +Z axis lower surface 96a of metal part 96 into the first contact portion 70a.

[0240] The contact flat surface 70a' can be ground concentrically around the original first contact portion 70a. Specifically, a small flat surface is machined on a grinding wheel machine (as indicated by the dotted line in Figure 45), transforming the connecting area with metal piece 96 into the first contact portion 70a. By changing the connection between connector 70 (equivalent to the conductive member in Embodiment 1) and metal part 96 from point contact to planar contact, this reduces vibration-induced instability (from printer operation or external sources) affecting contact stability, improving ground signal transmission reliability. Alternatively, the contact flat surface 70a' can be formed by extruding a small flat on the original first contact portion 70a, still designated as first contact portion 70a.

[0241] The connector 70 in this implementation includes: a first contact portion 70a, a second contact portion 70b, a semi-closed ring 70c, a first bending space 70d, a second bending space 70e, a third bending space 70f, a fourth bending space 70g. According to the bending condition of the profile, the connector 70 is divided into a first part 701, a second part 702, a third part 703, a fourth part 704, a fifth part 705, a sixth part 706, a seventh part 707, and an eighth part 708, a ninth part 709, a tenth part 710, an eleventh part 711.

[0242] Among them, the second part 702, the fourth part 704, the sixth part 706, the seventh part 707, the eighth part 708, and the tenth part 710 are bending areas. The first contact portion 70a is located on the fourth part 704. Viewed in the Z axis direction, the first contact portion 70a is located at the end of the connector 70 in the -Z direction, and abuts against the lower surface 96a of the +Z axis of the metal piece 96. The first contact portion 70a is located in the -Z axis direction of the second contact portion 70b.

[0243] The part portion 704 is located on the -Z axis side compared to other parts of the connector 70. The semi-closed ring 70c is located on the -Y axis side of the connector 70. The semi-closed ring 70c is a space composed of the first part 701, the second part 702, the third part 703, the fourth part 704, and the fifth part 705. The tilt directions of the third part 703 and the fifth part 705 are different. When viewed along the Y axis direction, the third part 703 tilts towards the -Z axis direction, and the fifth part 705 tilts towards the +Z axis direction.

[0244] That is, the third part 703 tilts toward the +Y axis and -Z axis directions, and the fifth part 705 tilts toward the +Y axis and +Z axis directions. The third part 703, the fourth part 704, and the fifth part 705 together form a mountain peak shape, and the fourth part 704 is located on the most -Z axis side. At least a part of the fifth part 705 is located on the -Z axis direction side of the sixth part 706 to the eleventh part 711.

[0245] When the ink cartridge 10 is mounted onto the mounting portion 90, the fifth part 705 will first contact the metal piece 96 (at the same time, if the printer is provided with a mounting portion protection component in the -Y axis direction of the metal piece 96, the fifth part 705 will first contact the metal piece 96. The fifth part 705 contacts the mounting portion protection component, and only contacts the metal piece 96 after passing the mounting portion protection component). As the ink cartridge 10 is continuously mounted along the mounting direction D2, the -X axis side of the connecting component 70 and the semi-closed ring 70c will be compressed and deformed to a certain extent until the entire connector 70 enters the mounting portion 90. At this time, the first contact portion 70a abuts against the lower surface 96a of the metal piece 96. During the above mounting process, the fifth part 705 serves to guide the mounting of the connector 70 to the mounting portion 90 and guide the deformation of the connector 70, and finally completes the abut between the first contact portion 70a and the metal piece 96.

[0246] When the ink cartridge 10 is to be separated from the mounting portion 90 and the chip 20 is separated from the contact pin assembly 91 of the printer, the first contact portion 70a will not be separated from the metal piece 96. When the ink cartridge 10 is completely separated from the mounting portion 90, the first contact portion 70a will be separated from the metal piece 96.

[0247] Further, before the first contact portion 70a is separated from the metal piece 96, as the ink cartridge 10 continues to move out in the direction opposite to the mounting direction D2, the third part 703 will play a guiding and buffering role to prevent the connector 70 from being stuck on the metal piece 96 when the ink cartridge 10 is detached from the mounting portion 90, and finally the ink cartridge 10 can be taken out smoothly.

[0248] With this arrangement, when the ink cartridge 10 is separated from the mounting portion 90, the connector 70 will return to its initial state under the action of its own elastic force. The initial state of the connector 70 (when the connector 70 is not yet mounted on the mounting portion 90) and the abutting state (when the connector 70 is mounted on the mounting portion 90) are benefit for better contact between the connector 70 and the metal piece 96, and reduce the occurrence of unstable contact situations.

[0249] The seventh part 707 and the eighth part 708 are both bent into a U-shaped structure with an opening facing in the +Z-axis direction, which can be combined with the first edge 403 and the second edge 404 of the ink supply head 40 to fix the conductive component, thereby allowing the connector 70 to withstand the pressure from the metal piece 96 on the -Y axis side portion of the connector 70, as well as the pressure from the chip 20 on the second contact section 70b. It also ensures the elastic recovery force of the connector 70, ensuring that the connector 70 can switch between its initial state and the abutting state.

[0250] A third bending space 70f of a U-shaped structure with an opening facing the -Z axis direction is formed between the seventh part 707 and the eighth part 708. Some movable buckles can be provided on the ink supply head 40, and the movable buckles are engaged with the third bending space 70f to prevent the connector 70 from detaching from the ink supply head 40.

[0251] The second contact portion 70b is formed on the tenth part 710. The second contact portion 70b abuts against the fifth terminal 135 of the chip 20, and the chip 20 will give a certain pressure to the second contact portion 70b, to ensure better contact between the second contact portion 70b and the fifth terminal 135. The tenth part 710 can be ground to form a small flat surface at the bent point to form a second contact portion, thereby allowing the connector 70 to contact the chip 20 more stably.

[0252] As shown in Figures 43 to 46, the connector 70 has no offset position in the X axis direction. That is, when viewing the ink cartridge 10 along the -Y axis direction, the projection of the connector 70 is on the same line perpendicular to the X axis. Therefore, the projection of the first contact portion 70a on the chip 20 is located on the fifth terminal 135, the projection of the first contact portion 70a on the chip 20 is located in the first region R1, and the projection of the first abutting portion 70a on the chip 20 is located on the -X axis position side of chip 20. The existence of the eleventh part 711 can prevent the connector 70 from scratching the fifth terminal 135 during the manufacturing process, thereby avoiding damage to the fifth terminal 135.

[0253] It should be noted that, as shown in Figures 47 and 48, the ink cartridge 10 also includes a chip mounting portion 201. The chip mounting portion 201 is used to hold the chip 20. The chip 20 is fixed on the ink cartridge 10 through the chip mounting portion 201. The chip mounting portion 201 has: a through groove 2011, an accommodating portion 2012, a flat surface 2013, a positioning post 2014, and a fixing portion 2015.

[0254] The flat surface 2013 is in contact with the rear surface 120b of the chip 20 and is used to position the chip 20. The accommodating portion 2012 is used to accommodate the memory 100. The positioning posts 2014 match the first to fourth holes of the chip 20 to ensure that the chip 20 is fixed on the chip mounting portion 201. The connector 70 passes through the through slot 2011 and abuts against the fifth terminal 135 of the chip 20. As shown in Figure 31, all or at least part of the ninth part 709, the tenth part 710, and the eleventh part 711 of the connector 70 are accommodated in the through groove 2011.

[0255] The fixing portion 2015 is a protrusion disposed on the chip mounting portion 201, which matches with the fixing groove 451 on the ink supply head 40, and is used to fix the chip mounting portion 201. Some buckles can be provided on the fixing portion 2015 and engaged with the fixing groove 451 through the buckles. This arrangement can reduce the chip mounting portion 201 from being separated from the ink supply head 40 under the elastic force of the connector 70.

[0256] The ink supply head 40 has an upper surface 40a on the -Z axis side, a protruding portion, and an bearing portion 45. The protruding portion is located on the -Y axis side of the upper surface 40a. The protruding portion may have only the first protruding portion 43 (as shown in Figure 50 ), or may have the first protruding portion 43 and the second protruding portion 44 (as shown in Figure 50 ). When the protruding portion includes the first protruding portion 43 and the second protruding portion 44, they can serve as gripping parts for the user to mount the ink cartridge 10 onto the tray 97 along the mounting direction D1 or to remove the ink cartridge 10 in the direction opposite to the mounting direction D1. By gripping the sides of the first protruding portion 43 and the second protruding portion 44, the user can move the ink cartridge 10, facilitating removing and mounting the ink cartridge 10.

[0257] The ink supply head 40 also includes: a first protrusion 401, a second protrusion 402, a first edge 403, a second edge 404, and a fixing groove 451. The fixing groove 451 is used to fix the chip mounting portion 201. When the connector 70 is mounted on the ink supply head 40, the first protrusion 401 is located in the semi-closed ring 70c of the connector 70, which reduces the occurrence of the connector 70 being separated from the ink supply head 40.

[0258] The second protrusion 402 is located within the first bending space 70d of the connector 70, thereby reducing the occurrence of the connector 70 detaching from the ink supply head 40. The first edge 403 engages with the seventh part 707, and they can be in an interference fit state, which reduces the occurrence of the connector 70 detaching from the ink supply head 40; the second edge 404 interacts with the eighth part 708, and they can be in an interference fit state, which reduces the occurrence of the connector 70 detaching from the ink supply head 40. Some movable buckles can be provided on the ink supply head 40, and the movable buckles are engaged with the third bending space 70f to prevent the connector 70 from detaching from the ink supply head 40.

[0259] The first protrusion 401 is provided with an inclined surface 401a on the -Z axis side, the second protrusion 402 is provided with an inclined surface 402a on the -Z axis side, the first edge 403 is provided with an inclined surface 403a on the -Z axis side, and the second edge 404 is provided with an inclined surface 404a on the -Z axis side. The above inclined surfaces play a guiding role when the connector 70 is mounted on the ink supply head 40.

[0260] Further, as shown in Figure 52, in this embodiment, the ink supply head 40 of the ink cartridge 10 is provided with widening members 46 on the +X axis side and the -X axis side, which increases the width of the ink cartridge 10 in the X axis direction. It is beneficial to widen the width of the ink bag 10a and increase the ink capacity of the ink bag 10a. At the same time, it can be understood that the tray 97 will also be widened in the X axis direction. It should be noted that in this embodiment, when the ink cartridge 10 is mounted onto the printing device, the connector 60 (conducting member) contacts the grounding component first, and the chip 20 contacts the contact pin assembly 91 later.Fourth implementation of Embodiment 3:

[0261] In the fourth implementation, this implementation provides a ground conductive member based on the above implementations, in which one end of the conductive member is electrically connected to the grounding terminal of the chip, and the other end extends downward to electrically connect to the conductive swing bar, and the electrical connection position of the two is located below the chip, and is further connected to the grounding component through the conductive swing bar.

[0262] Specifically, as shown in Figures 53 and 54, the ink cartridge body 50 also includes a bottom case 51 (equivalent to the ink supply head 40 in the second and the third implementations). In the mounting direction D2 (+Y axis direction), at least a part of the connector 70 is disposed on the front end side of the front surface 51a. A space Q is formed between the connector 70 (equivalent to the conductive member) and the front surface 51a. The space Q can accommodate a part of the mounting portion 90; at least a part of the connector 70 is disposed below the bottom surface 51b of the ink cartridge 10.

[0263] Further, as shown in Figure 55, the connector 70 is configured as a first conductive sheet, and a conductive swing bar is disposed at the bottom of the accommodation cavity. The conductive swing bar is located at the bottom of the ink cartridge body and can restrict the position of the ink cartridge body. In this embodiment, the locking portion 94 is a rod-shaped component that can reset and swing. That is, the locking portion 94 is configured as a conductive swing bar. The upper surface of the locking portion 94 can be electrically connected to the first conductive sheet, and the electrical connection position of the two is located below the chip.

[0264] After adopting the above technical solution, the space Q between the connector 70 and the front surface 51a is used to restrict the position of the mounting portion 90, so that the connector 70 can contact the locking portion 94 and connect only when the space Q and the mounting portion 90 are well matched. Only after the component 70 contacts the locking portion 94 can the ground signal of the chip 20 be transmitted normally.

[0265] Furthermore, a part of the connector 70 can also be accommodated in the space Q. For example, one side of the connector 70 is arranged in an "n" shape, and a part of the connector 70 is also arranged in the space Q. As shown in Figure 56, the connector 70 further includes an extending portion 710 disposed in the space Q and between the space Q and the front surface 51a. With such a structure, the space Q is still set between connector 70 and front surface 51a. As long as a part of the connector 70 meets this description, it is consistent with the characteristics of the space Q formed between the connector 70 and the front surface 51a.

[0266] The space Q formed between the connector 70 and the front surface 51a can accommodate the front wall 97aa of the tray 97. The space Q is restricted by the front wall 97aa, and the conductive member itself is in contact with the grounding component. Further, the bottom of the accommodation cavity has a bottom wall 97bb, and the grounding component may also be the bottom wall 97bb of the accommodation cavity.

[0267] Continuing to refer to Figures 53 to 56, it can be seen that a part of the connector 70 is connected to the chip 20, and the other part is connected to the grounding component of the mounting portion 90. The connector 70 serves as both a mechanical means and a chip signal detection means to ensure that the ink cartridge is correctly mounted on the mounting portion 90 of the printer.

[0268] The space Q between the connector 70 and the front surface is used to match the front wall 97aa of the tray 97. Only when the front wall 97aa enters the space Q can the tray 97 and the ink cartridge 10 be properly mounted and positioned. When the assembly is mounted onto the mounting portion 90, the connector 70 is in contact with the upper surface of the locking portion 94, so that the detection of the chip model can be completed and the ink cartridge 10 can be ensured to pass the detection of the chip signal detection means; the mechanical means and the chip signal detection means are combined to more comprehensively ensure that the ink cartridge is correctly mounted on the printer.

[0269] Further, it should be noted that the ink cartridge 10 includes a chip 20, a bottom case 51, an ink bag 10a, a connector 70, holes 220 and 210, a front surface 51a located in the +Y axis direction, and a bottom surface 51b located in the +Z axis direction, an ink outlet 41, a tray 97 with a front wall 97aa and positioning holes 971 and 972.

[0270] The locking portion 94 has an upper surface 94a in the -Z axis direction. After the ink cartridge 10 is mounted on the mounting portion 90, the ink supply portion 92 (ink filling tube) matches the ink outlet 41 and can provide ink to the printer for printing. The contact pin assembly 91 of the printer contacts the communication terminal of the chip 20 to provide transmission of chip signals.

[0271] The columnar positioning portions 93f and 93s cooperate with the positioning holes 971 and 972 on the tray 97 and the holes 220 and 210 on the ink cartridge to restrict the position of the assembly in the mounting portion; the protrusion 941 on the locking portion 94 is used to cooperate with the groove at the bottom of the tray 97 to fix the assembly of the ink cartridge 10 and the tray 97; the connector 70 cooperates with the front wall 97aa of the tray 97, and the connector 70 contacts the upper surface 94a of the locking portion 94 to transmit the ground signal.Fifth implementation of Embodiment 3:

[0272] On the basis of the above implementation, this implementation provides another antenna-type conductive member, in which the conductive member is composed of a conductive sheet and a conductive film of part of the ink bag. The specific implementation is as follows:

[0273] The conductive member provided in this implementation includes a first conductive sheet 71 and a first conductive transmission medium body; the ink cartridge body includes an ink storage portion, and the ink storage portion has an ink chamber enclosed by a film layer structure, the film layer structure comprises an insulating outer film, a conductive intermediate film, and an insulating inner layer that are stacked sequentially from the outer to the inner layer; the conductive intermediate film is configured as the first conductive transmission medium body, and at least part of the conductive intermediate film is used to electrically connect the first conductive sheet and the grounding component.

[0274] Exemplarily, as shown in Figures 57 and 58, the ink cartridge in this embodiment includes an ink storage portion disposed in the ink cartridge body. The ink storage portion is configured as an ink bag 10a. The ink bag 10a has an ink chamber enclosed by a film layer structure. The ink chamber is used to store ink.

[0275] For example, the ink bag has an upper surface and a lower surface, and the upper surface and the lower surface are the outer surfaces of the film layer structure. The film layer structure comprises an insulating outer film, a conductive intermediate film, and an insulating inner layer that are stacked sequentially from the outer to the inner layer. The insulating outer film forms the outer surface of the ink bag. The outer surface includes the above-mentioned upper surface and lower surface. The insulating inner film forms the inner surface of the ink bag and in contact with the ink, the conductive interlayer film is disposed between the insulating outer film and the insulating inner film, and at least part of the conductive interlayer film can be used as the above-mentioned first conductive transmission medium body to be regarded as part of the conductive member, and the intermediate film can be electrically connected to the grounding component.

[0276] In the embodiment of the present application, part of the conductive intermediate film is exposed on the outer surface of the film layer structure and forms a first electrical connection portion. The first electrical connection portion can be electrically connected to the first conductive sheet, and the other end of the first conductive sheet is electrically connected to the grounding terminal of the chip. For example, the insulating outer film includes a first hollow portion, the first hollow portion is disposed close to the first conductive sheet, and a part of the conductive intermediate film is exposed to the first hollow portion and forms a first electrical connection portion.

[0277] A portion of the conductive intermediate film is exposed on the outer surface of the film structure and forms a second electrical connection portion. The second electrical connection portion can be opposite to the first electrical connection portion and be electrically connected through the unexposed conductive intermediate film between them, the second electrical connection portion is electrically connected to the grounding component.

[0278] For example, the insulating outer film includes a second hollow portion, at least part of the conductive intermediate film is exposed in the second hollow portion, and forms a second electrical connection portion, and the second electrical connection portion and the first electrical connection portion are electrically connected through the part of the conductive intermediate film, to transmit the ground signal; that is, the ground signal between the chip and the printer is transmitted through the first conductive sheet, the intermediate conductive film and the grounding component. This setting improves the grounding stability of the ink cartridge and reduces the occurrence of grounding failure or instability.

[0279] On the basis of the above implementations, in this implementation, the grounding component may be the outer frame of the mounting portion 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, +Y axis directions) or a part of the outer frame, such as the cavity wall forming the accommodation cavity, serves as the grounding component. The first electrical connection portion is located on the Y axis side of the ink bag 10a, and the above-mentioned second electrical connection portion is located on the -Y axis side of the ink bag, and the second electrical connection portion is on the -Z axis side of the first electrical connection portion, that is, the second electrical connection portion is closer to the cavity wall of the accommodation cavity than the first electrical connection portion.

[0280] It should be noted that the film layer structure of a local area on the surface of the ink bag 10a has four layers of film: along the direction from the outside to the inside of the ink bag 10a, the first layer of film is made of PET, so the first layer of film is also called PET film, that is, the insulating outer film; the second film is made of Al and is conductive, also known as aluminum film, metal film or intermediate conductive film 10a1; the third layer of film is nylon film; the fourth layer of film is made of PET140, so the fourth layer of film is also called PET140 film.

[0281] Other areas on the surface of the ink bag 10a are only provided with three layers of film, that is, this area is exposed to the outer surface of the film layer structure. Along the direction from the outside to the inside of the ink bag 10a, there are the aforementioned conductive film 10a1, the nylon film and the PET140 film. Since the conductive film 10a1 is located on the outermost side in these areas, these areas are also called conductive areas of the ink bag 10a. In other words, the conductive areas form electrical connection portion. Among them, the conductive films 10a1 in all areas on the ink bag 10a are connected. That is to say, whether it is an area with three layers of film or an area with four layers of film on the ink bag 10a, they all have the same layer of conductive film 10a1. At the same time, the conductive film 10a1 is isolated from the ink stored in the ink bag 10a. Therefore, in this solution, the ink does not participate in the transmission of ground signals.

[0282] In the implementation of the present application, a part of the first conductive sheet 71 is connected to the chip 20, and the other part is connected to the conductive film of the conductive area A of the ink bag 10a (first electrical connection portion). The first conductive sheet 71 has a first part 71a and a second part 71b. The first part 71a is connected to the chip 20, and the second part 71b is connected to the conductive film.

[0283] After the conductive film in the conductive area A is connected to the first conductive sheet 71, the -Z axis side of the connection between the two is covered with a PET material film to make the appearance of the ink cartridge 10 more beautiful, or an adhesive member (such as tape, etc.) is used to fix the connection between the two, so as to make the connection between the first conductive sheet 71 and the first electrical connection portion more stable.

[0284] As shown in Figure 59, in this embodiment, the -Y axis side end of the ink bag 40 extends in the -Z axis direction, and the -Z axis side surface of the end has a conductive area B, and this conductive area is the second electrical connection portion, the conductive film 10a1 of the conductive area B is connected to the metal piece 96 of the outer frame on the +Z axis side of the mounting portion 90, and the metal piece 96 forms the cavity wall of the accommodation cavity, thereby realizing the transmission of the ground signal between the chip 20 and the printer 1.

[0285] It should be noted that a conductive area can be provided anywhere on the ink bag 10a, and the conductive film in this area can be connected to the metal piece 96 of the mounting portion 90. For example, except for the -Y axis end of the ink bag 10a, the conductive film at the +Y axis side, +X axis side, -X axis side, -Z axis side or +Z axis side position of the ink bag 10a can be connected to the metal piece 96 of the mounting portion 90.

[0286] As shown in Figures 60 and 61, based on the above implementations, the ink cartridge provided by the embodiment of the present application also includes a second conductive sheet 72. The second conductive sheet 72 and the first conductive sheet 71 are spaced apart. The sheet 72 has a first part 72a and a second part 72b. The first part 72a is connected to the conductive film on the conductive area C of the ink bag 10a. The second part 72b is connected to the metal piece 96 of the mounting portion 90. The ground signal is transmitted to the chip 20 through the metal piece 96 the second conductive sheet 72, the conductive film, and the first conductive sheet 71; and the -Y axis end of the ink bag 40 is not in direct contact with the metal pieces of the mounting portion 90.

[0287] Optionally, after the conductive film in the conductive area C is connected to the second conductive sheet 72, the -Z axis side of the connection between the two is covered with a PET material film to make the appearance of the ink cartridge 10 more beautiful, or an adhesive member ( (such as tape, etc.) is used to fix the connection between the two, so as to make the connection between the second conductive sheet 72 and the conductive film 10a1 is more stable.

[0288] In the above solution, the metal pieces of the mounting portion 90 may be the outer frame of the mounting portion 90 (the outer frame in the +Z axis, -Z axis, +X axis, -X axis, +Y axis directions) or a part of the outer frame. For the safety of the user, the metal pieces of the mounting portion 90 are all grounded, and the ground signals between them and the printer are all interconnected.

[0289] In this embodiment, the second conductive sheet 72 first extends in the -Z axis direction from the conductive area C of the ink bag 10a, then extends to the -X axis side or the +X axis side until it crosses the tray 97, and then extends in the +Z axis direction and is connected to the outer frame of the +Z axis side of the mounting portion 90.

[0290] It should be noted that the number of the second conductive sheets 72 is not limited. For example, one or more second conductive sheets 72 may be provided, and the position where the second conductive sheets 72 are disposed on the ink bag 10a is not limited. For example, the second conductive sheets 72 may be disposed on the upper surface or the lower surface of the ink bag 10a, and the second conductive sheets 72 can be disposed on the +X axis side, -X axis side, +Y axis side or -Y axis side of the ink bag 10a.Sixth implementation of Embodiment 3:

The description of the ink cartridge in this implementation is consistent with the content of the fourth implementation of the Embodiment 3. The chip used is the Variation 1 of the chip or the Variation 3 of the chip, which will not be described again here.Seventh implementation of Embodiment 3:

[0292] Figure 63 is a schematic diagram of an ink cartridge according to the seventh implementation of the Embodiment 3 of the present application. The description of the ink cartridge in this embodiment is consistent with the content of the first to the third implementation of the Embodiment 3. The chip used is the Variation 1 of the chip or the Variation 3 of the chip, which will not be described again here.Embodiment 4:

[0293] On the basis of the above-mentioned the Embodiment 1, the embodiment of the present application also includes a conductive support plate 82, the mounting portion 90 is slidably provided on the guide rail 86; the guide rail 86 and the conductive support plate 82 are provided with a barrier plate 85; the conductive support plate 82 is disposed on the side of the barrier plate 85 away from the mounting portion, and the length direction of the conductive support plate 82 is consistent with the extension direction of the guide rail 86, for example, the conductive support plate 82 is disposed parallel to the horizontal plane, and the conductive support plate 82 and the conductive wall plate 81 are arranged opposite to each other on both sides of the grounding guide rail 80. Correspondingly, the conductive member includes a bridging portion, so that the conductive member crosses the barrier plate 85, that is, the bridging portion straddles above the barrier plate 85, and the portion of the bridging portion close to the conductive support plate can be in contact with the conductive support plate and is electrically connected.

[0294] As shown in Figure 66, the guide rail 86 may be a conductive member that carries a ground signal, or it may be a non-conductive member that does not carry a ground signal. When the guide rail 86 carries a ground signal, its conductive support plate 82 may be a part of the guide rail, or the guide rail 86 and the conductive support plate 82 may belong to two different components. The barrier plate 85 is a non-conductive member that does not carry a ground signal (for example, the barrier plate 85 is made of non-conductive plastic). Therefore, in this embodiment, the conductive member must cross the barrier plate 85 to abut against the conductive support plate 82 to achieve the beneficial effects of this application.

[0295] Specifically, as shown in Figures 64 and 65, in this embodiment, the chip 20 is disposed on the front end side of the ink cartridge 10 in the mounting direction, and the memory 100 is disposed on the rear surface 120b of the chip 20. A conductive sheet 140a is disposed between the chip 20 and the ink cartridge 10. The shape of the conductive sheet 140a is roughly the same as that of the chip 20. An opening 111 consistent with the shape of the memory 100 is disposed in the middle of the conductive sheet 140a. The size of the opening 111 is just enough to accommodate the protruding part of the memory 100 to pass through. After the mounting of the chip 20 and the conductive sheet 140a is completed, the grounding terminals 137a and 137b are attached and connected.

[0296] The connector 140 is configured as a conductive member. The connector 140 (equivalent to the conductive member) is made of a conductive material with a certain hardness. One end of the connector 140 (equivalent to the conductive member) is connected to the conductive sheet 140a through solder. Of course, the connector 140 and the conductive sheet 140a may be integrally formed sheet metal pieces, or may be a structure composed of a plurality of parts connected. Optionally, the conductive sheet 140a may not be provided in this embodiment, and the connector 140 (equivalent to a conductive member) may be directly connected to the grounding terminal to transmit the ground signal.

[0297] As shown in Figures 66 to 70, the other end of the connector 140 can extend along the first side wall 50a of the ink cartridge body 50 in the -Y axis direction, or along the second side wall of the ink cartridge body in the +Y direction (which is arranged opposite to the first side wall 50a and not shown in the figure), or along the top wall 50d of the cartridge body in the +Z direction, extending in a direction away from the chip 20 to the rear side wall of the chip 10 until close to the end of the connector 140. The connector 140 is bent in a direction away from the surface of the ink cartridge 10 to form a bridging portion 140b, and is connected to the conductive support plate 82 of the grounding guide rail. Further, the ground signal between the chip 20 and the printer is transmitted through the conductive sheet 140a, the connector 140, and the conductive support plate 82.

[0298] It should be noted that the above-mentioned guide rail 86 is a component used to carry the mounting portion 90. For the safety of the user, the ground signals between the guide rail 86 and the printing device are interconnected. The conductive support plate 82 is a metal piece in the printing device. For the safety of the user, the ground signals between the conductive support plate 82 and the printing device are interconnected. With this arrangement, after adopting the above technical solution, the ground signal is transmitted to the chip 20 through the conductive support plate 82 and the connector 140, which improves the stability, reduces the situation of failure to ground or unstable grounding, and achieves the beneficial effects of the present application.

[0299] On the basis of the above embodiments, in the embodiment of the present application, an end of the conductive member close to the grounding component is provided with an abutting portion, and the abutting portion is configured to contact the conductive support plate 82, so that the conductive member is electrically connected to the conductive support plate 82 and the conductive wall plate.

[0300] Furthermore, since the mounting portion is slidably mounted on the guide rail, in order to ensure the smooth sliding of the mounting portion, in the embodiment of the present application, the abutting portion can be configured as a ball or a ball bearing. The ball and ball bearing serve as a part of the conductive member and are connected with the guide rail, and are electrically connected to the conductive member. Such arrangement can reduce the friction between the abutting portion and the conductive support plate or conductive wall plate, ensuring that the mounting portion and the ink cartridge 10 slide smoothly on the grounding guide rail.

[0301] In another embodiment, the conductive member not only includes a second conductive sheet, but also includes a second conductive transmission medium body electrically connected to the second conductive sheet, and a carrier electrically connected to the second conductive transmission medium body, that is, in this embodiment, the conductive member is composed of a conductive sheet, a conductive transmission medium and a carrier.

[0302] Further, the carrier is disposed close to the chip, that is, the carrier is located at an end of the ink cartridge body away from the guide rail. One end of the carrier is connected to the grounding terminal of the chip, and the other end of the carrier extends into the ink chamber of the ink cartridge body and is electrically connected to the printing liquid medium in the ink chamber. For example, the printing liquid medium is ink, and the ink serves as a conductive medium and is connected to the carrier, so that the ground signal of the grounding terminal is transmitted to the ink through the carrier.

[0303] Further, one end of the second conductive sheet extends into the ink chamber and can be in contact with the ink. The other end of the second conductive sheet forms a bridging portion and is disposed above the barrier plate 85 through the bridging portion. The bridging portion can be electrically connected to the conductive support plate, so that the ground signal is transmitted from the ink to the conductive support plate through the second conductive piece.

[0304] For example, as shown in Figure 71, the connector 140 is configured as the above-mentioned second conductive sheet, which serves as a part of the conductive member and is made of a conductive material with a certain hardness. The connector 140 may be an integrally formed sheet, or may be a structure composed of a plurality of parts connected, and the embodiment of the present application is not limited to this.

[0305] The connector 140 also includes a fixing part 141. The fixing part 141 can be made of silicone material. The middle part of the fixing part 141 has a through hole that can accommodate the bent portion 1402 of the connector 140. The mounting method of the connector 140 is as follows: fitting the fixing part 141 into the connector 140 first, then inserting the vertical portion 1401 of the connector 140 with the fixing part 141 into the through hole in the upper part of the rear side wall 50b of the ink cartridge 10, and adjusting the position of the fixing part 141 to block the above-mentioned through hole and making the connector 140 be in the preset position and orientation relative to the ink cartridge 10.

[0306] As shown in Figure 73, the state of the connector 140 after the mounting is as follows: the vertical portion 1401 of the connector 140 is attached to the inner side of the rear side wall 50b in the ink cartridge 10, extending from the end of the bottom of the rear side wall 50b close to the ink outlet 41 in the +Z axis direction to the top of the rear side wall 50b, and is fixed to the ink cartridge 10 through the fixing part 141. The fixing part 141 can seal the rear side wall 50b, not only preventing ink leakage but also fixing the connector 140. The bent portion 1402 of the connector 140 extends out of the outside of the ink cartridge 10 from the through hole of the fixing part 141, bends in the direction away from the surface of the ink cartridge 10, and is connected to the metal part on the printer, and this metal part is the above-mentioned conductive support plate 82.

[0307] As shown in Figure 72 and Figure 75, the conductive member 140a is the above-mentioned carrier, which is made of conductive silicone material and is embedded in the mounting surface of the ink cartridge 10 to seal the ink cartridge 10 and make contact with the ink. Specifically, the conductive member 140a is placed behind the chip 20, and the memory 100 is disposed on the rear surface 120b of the chip 20. The conductive member 140a is provided with an opening 111, and the opening 111 is arranged in cooperation with the memory 100, so that the size of the opening 111 is just enough to accommodate the memory 100.

[0308] In the mounted state, the chip 20 is at least partially attached to the conductive member 140a on the side corresponding to the rear surface 120b. The seventh terminals 137a and 137b (grounding terminals in this application) are abut against the conductive member 140a. The first surface 140b of the conductive member 140a is used to connect with the chip 20, and the second side 140c (facing the internal accommodating cavity of the ink cartridge 10) is in contact with the ink and is electrically connected.

[0309] As shown in Figures 76 and 77, the connector 140 is placed in the -X axis direction of the ink cartridge 10, and the conductive member 140a is placed in the +X axis direction of the ink cartridge 10. Since the ink in the ink cartridge 10 has conductive properties, in this embodiment the ground signal between the chip 20 and the printer can be transmitted through the conductive member 140a, the ink, the connector 140, and the conductive support plate 82.

[0310] Certainly, the grounding method of the ink cartridge involved in this embodiment is also applicable to other types of chips. For example, there are four terminals on the front side of the chip 20, and a grounding terminal (not shown in the figure) is provided on the back side. This grounding terminal can also utilize the conductive member 140a, the ink, the connector 140, and the conductive support plate 82 to achieve the transmission of the ground signal between the chip and the printer. (The component 1401 is located inside the chamber of the ink cartridge and is electrically connected to the ink.)

[0311] After adopting the above technical solution, the ground signal is transmitted to the chip 20 through the conductive support plate 82, the connector 140, the ink, and the conductive member 140a, which improves the stability and reduces the situation that the ground cannot be connected or the ground is unstable. When the ink is used up or is about to be used up, the ground signal on the chip 20 cannot be connected to the printer, and the printer will display a prompt that the ink cartridge is not mounted. This can serve as a warning to the user to replace the ink cartridge as the printer itself prompts that the ink is exhausted.Embodiment 5

[0312] In order to facilitate the description of the embodiments of the present application, the coordinate system in the drawings is first described, in which the X axis is the first direction, the Y axis is the second direction, and the second direction is defined as the reciprocating sliding direction of the mounting portion; the Z axis is the third direction, the third direction is defined as the direction in which the ink cartridge assembly is inserted into the mounting portion, and the first direction is defined as the normal direction of the plane formed by the second direction and the third direction.

[0313] As shown in Figures 78 and 79, based on the above-mentioned the Embodiment 1, the printing device provided by the embodiment of the present application also includes a conductive unit 300 and a mounting portion 90. The conductive unit 300 is configured as a grounding component of the printing device. For example, the conductive unit 300 may be the above-mentioned grounding guide rail or the above-mentioned conductive support plate, or other metal components for transmitting ground signals, which are not limited in the embodiment of the present application.

[0314] The conductive unit 300 in the embodiment of the present application is disposed outside the mounting portion 90, and the conductive unit 300 can be configured for the transmission of the ground signal. The length extension direction of the conductive unit 300 is consistent with the second direction. A rail (not shown in the figure) is provided in the printing device adjacent to the conductive unit 300. The mounting portion 90 can be slidably mounted on the rail. When the printing device is working, the mounting portion 90 can slide along the rail, and the extension direction of the rail is consistent with the extension direction of the conductive unit 300, that is, the mounting portion 90 can linearly slide in the second direction relative to the conductive unit 300.

[0315] The printing device provided by the embodiment of the present application also includes an ink cartridge assembly. The ink cartridge assembly can be detachably mounted on the printing device. The mounting portion 90 includes a housing and a contact pin assembly 91 disposed in the housing. The housing is provided with an accommodation cavity 995 for inserting and mounting the ink cartridge assembly, and the contact pin assembly 91 is disposed in the accommodation cavity 995.

[0316] A part of the contact pin assembly 91 is located in the accommodation cavity 995 and is used for electrical connection with the ink cartridge assembly; the other part of the contact pin assembly 91 is connected to the printing circuit of the printing device, and when the ink cartridge assembly is inserted into the housing, a communication with the printing device is established by the contact pin assembly.

[0317] In order to realize that the ground signal in the conductive unit 300 is transmitted to the ink cartridge assembly, the ink cartridge assembly provided by the embodiment of the present application also includes a connecting assembly, the connecting assembly is configured as a conductive member, and the ink cartridge assembly receives the ground signal transmitted by the conductive unit 300 through the conductive member.

[0318] Specifically, the ink cartridge assembly includes at least one ink cartridge 10, and each ink cartridge 10 can be inserted into the accommodation cavity 995 and electrically connected to the corresponding contact pin assembly 91, and the number of contact pin assemblies 91 is equal to the number of the ink cartridges 10.

[0319] As shown in Figures 80 and 81, each ink cartridge 10 includes a cartridge body 50 and a chip 20 provided on the cartridge body 50. The chip 20 includes a substrate 21, a plurality of contacts and storage element 24 (storage element 24 is disposed on the back side of the substrate 21, see Figure 95 for arrangement), in which a plurality of contacts are electrically connected to the storage element 24.

[0320] Exemplarily, the plurality of contacts include a grounding contact 23, which is used to transmit and receive ground signals, and the grounding contact 23 is configured to be in contact with the above-mentioned connecting assembly (electrical contact with the conductive member), that is, a grounding contact 23 is not in contact with either contact pin. Further, the remaining contacts 22 are configured as one or more of storage element contacts, high voltage contacts, detection contacts (such as short circuit detection between contacts or mounting detection of ink cartridges, etc.), and the remaining contacts 22 are in contact with and electrically connected to each contact pin of the corresponding contact pin assembly 91.

[0321] It should be noted that in the embodiment of the present application, the storage element contacts and / or detection contacts are electrically connected to the storage element 24, and the storage element 24 stores communication and data processing programs, ink volume information of the ink cartridge, and / or related products information of the ink cartridge, etc. Alternatively, the chip 20 of the ink cartridge is provided with a high-voltage device, and the high-voltage contacts are electrically connected to the high-voltage device to detect short circuits between the contacts. Alternatively, the chip 20 of the ink cartridge is provided with a detection device, and the detection contacts are electrically connected to the detection device, so as to achieve the short circuit detection between contacts or mounting detection of ink cartridges, etc.

[0322] In the embodiment of the present application, the grounding contact 23 and the storage element 24 are located on different sides of the substrate 21, and the grounding contact 23 and the remaining contacts 22 are located on the same side of the substrate 21. For example, the grounding contact 23 and the remaining contacts 22 are located on the first surface of the substrate 21, and the remaining contacts 22 have a first projection relative to the first surface of the substrate, and the first projections of the plurality of remaining contacts 22 enclose a first area. The grounding contact has a second projection on the first surface, and the second projection is located outside the first area; in the second direction (Y axis direction), the second projection overlaps with the first area.

[0323] Furthermore, when the grounding contact 23 and the remaining contacts 22 are located on the same side of the substrate 21, a space 25 may be provided between the grounding contact 23 and the remaining contacts 22 in this embodiment. With this arrangement, ink or other impurities attached to the chip 20 during use can be stored in the space 25 to prevent the impurities from adhering to the chip 20 and causing a short circuit between the grounding contact 23 and the remaining contacts 22.

[0324] Referring to Figure 79, the connection assembly includes a first connecting component 61 and a second connecting component 62. Both the first connecting component 61 and the second connecting component 62 are capable of transmitting ground signals, wherein the first connecting component 61 is used to connect the second connecting component 62, and part of the first connecting component 61 is connected with the conductive unit 300 and form the external contact of the chip. For example, part of the first connecting component 61 is fixedly connected to the surface of the conductive unit 300 and has no relative displacement relative to the conductive unit 300.

[0325] Part of the first connecting component 61 is configured to follow the reciprocating movement posture of the mounting portion 90 and synchronously move dynamically, that is, part of the first connecting component 61 forms an external contact with the conductive unit 300, and can avoid the occurrence of sliding friction between the external contact and the surface of the conductive unit 300.

[0326] The second connecting component 62 is disposed on the mounting portion 90 and has no relative displacement relative to the mounting portion 90. For example, the second connecting component 62 is disposed in the accommodation cavity 995 and fixed relative to the housing of the mounting portion 90. One end of the second connecting component 62 is electrically connected to the grounding contact 23 of the chip 20, and the other end of the second connecting component 62 is connected to the first connecting component 61, so that the ground signal in the conductive unit 300 can be transmitted to the grounding contact 23 of the chip 20 through the first connecting component 61 and the second connecting component 62.

[0327] Compared with the solution in the related art that the external conductor is directly electrically connected to the conductive unit, and the external conductor slides on the surface of the conductive unit along the movement direction of the mounting portion following the movement of the mounting portion; in the embodiment of the present application, part of the first connection component 61 can follow the reciprocating movement of the mounting portion 90 to synchronize the dynamic displacement, so that the external contact formed by the fixed connection between the other part of the first connecting component 61 and the conductive unit 300 has no sliding friction relative to the conductive unit 300, which can avoid the generation of significant noise during the process of the external contacts sliding back and forth along the surface of the conductive unit 300, which might otherwise affect the user experience.

[0328] Furthermore, part of the first connecting component 61 can reciprocate with the mounting portion 90 to synchronize the dynamic displacement, which can prevent the external contacts (the part where the first connecting component 61 is connected to the conductive unit 300 is defined as the external contacts) from detaching from the surface of the conductive unit 300 due to reasons such as vibration. It also avoids the deformation of the external contacts caused by the long-term sliding friction between the external contacts and the conductive unit 300, thereby improving the grounding stability of the chip 20.

[0329] As shown in Figure 82, in order to facilitate positioning and supporting the second connecting component 62 when it is mounted on the accommodation cavity 995, the mounting portion 90 provided by the embodiment of the present application also includes a first supporting portion 991, along the third direction, the first supporting portion 991 is disposed above the contact pin assembly 91. For example, the first supporting portion 991 may be a partial support plane formed on the top of the housing, and along the first direction, the support plane is located on one side of each contact pin assembly 91; along the third direction, the support plane is located above each contact pin assembly 91.

[0330] In one embodiment, referring to Figures 79 and 80, the second connecting component 62 is inserted into the accommodation cavity 995, and part of the second connecting component 62 abuts against the first supporting portion 991, and part of the second connecting component 62 extends along the third direction to the side of the contact pin assembly 91 facing the chip 20, and when the ink cartridge assembly is inserted into the accommodation cavity 995, the portion of the second connecting component 62 extending to the contact pin assembly 91 contacts and is electrically connected to the ground contact 23 of the chip 20.

[0331] As shown in Figures 83 and 84, in this embodiment, the second connecting component 62 includes a body 621 and at least one extending portion 622, where the body 621 can abut against the first supporting portion 991 so that the second connecting component 62 can be inserted into the housing. The length extension direction of the body 621 is the same as the length extension direction of the first support portion 991, and both extend along the second direction. The body 621 can fit with the support surface of the first support portion 991.

[0332] The second connecting component 62 includes a plurality of extending portions 622, and the number of the extending portions 622 is consistent with the number of contact pin assemblies 91 (or the number of chips 20), that is, each extending portion 622 corresponds to one chip 20. The plurality of extending portions 622 are spaced apart on the body 621 along the second direction.

[0333] Each extending portion 622 is tooth-shaped, one end of the extending portion 622 is connected to the body 621, the other end of the extending portion 622 is configured to extend along the third direction, and the extending portion 622 can extend to the outside of the contact pin assembly 91; an electrical contact portion 6221 is provided on one side of the extending portion 622 facing the chip 20, and the electrical contact portion 6221 is used for electrical connection with the grounding contact 23 of the chip 20.

[0334] Further, the body 621 is provided with a first positioning portion 6211. Along the first direction, the extending portion 622 and the first positioning portion 6211 can be disposed at intervals on the body 621, and along the third direction, the first positioning portion 6211 can be disposed on the top of the second connecting component 62.

[0335] For example, the first positioning portion 6211 may be a horizontal plate, one end of the horizontal plate is connected to the body 621, and the other end of the horizontal plate extends along the first direction toward a side away from the body 621, that is, the horizontal plate has a horizontal surface that cooperates with the first supporting portion 991. When the second connecting component 62 is inserted into the mounting portion 90, the above-mentioned first positioning portion 6211 can fit closely with the supporting surface of the first supporting portion 991, which can at least restrict the second connecting component 62 in the third direction.

[0336] Based on the above embodiment, the above-mentioned body 621 is also provided with a second positioning portion 6212. The body 621 has an inclined surface, and a plurality of positioning grooves are provided on the inclined surface, and each positioning groove is configured as the above-mentioned second positioning portion 6212. The positioning groove extends along the third direction, and its top is disposed close to the first positioning portion 6211.

[0337] Exemplarily, the positioning groove is configured as a second positioning portion 6212, the first positioning portion 6211 is located above the top of the positioning groove, and the first positioning portion 6211 is located in the extension direction of the positioning groove. The bottom of the positioning groove has an opening, and the opening is located at the bottom of the inclined surface and is located close to the top of the extending portion 622. For example, the opening of the positioning groove may be disposed between two adjacent extending portions 622.

[0338] Referring to Figure 82, correspondingly, the mounting portion 90 is provided with spacers 992 that cooperate with the above-mentioned positioning grooves, that is, there are a plurality of spacers 992 spaced apart along the second direction in the accommodation cavity 995, and the spacers 992 extend along the third direction, a mounting space for the contact pin assembly 91 is formed between every two adjacent spacers 992. For example, the spacer 992 may be a spacer plate used to separate the contact pin assemblies 91.

[0339] Along the third direction, at least part of the spacer 992 protrudes from the contact pin assembly 91 and forms a second supporting portion 992a. The second supporting portion 992a cooperates with the positioning groove when the second connecting component 62 is inserted into the accommodation cavity 995., the positioning groove is embedded in the second support portion 992a, that is, the second positioning portion 6212 is inserted into the second support portion 992a, so as to restrict the position of the second connecting component 62 in at least the first direction and the second direction.

[0340] It should be noted that when the first positioning portion 6211 is fit closely the first supporting portion 991, the second positioning portion 6212 is inserted into the second supporting portion 992a at this time. That is, under the combined action of the first positioning portion 6211 and the second positioning portion 6212, the second connecting component 62 can be movably mounted into the mounting portion 90. Moreover, the grounding contact 23 of the chip 20 is electrically connected to the conductive unit 300 through the electrical contact portion 6221, the extending portion 622, the body 621 and the first connecting component 61, so as to realize the grounding of the chip 20.

[0341] Referring to Figure 81, in this implementation, the first connecting component 61 provided by the embodiment of the present application includes a conductive carrier, and the conductive carrier extends along the first direction, that is, the length direction of the conductive carrier is consistent with the sliding direction of the mounting portion 90.

[0342] The conductive carrier may be a conductive metal sheet that is flexible and deformable. The conductive carrier is disposed between the housing and the conductive unit 300. At least part of one end of the conductive carrier is fixed on the conductive unit 300, and the other end of the conductive carrier extends to above the housing, and is electrically connected to the body 621 of the second connecting component 62 or to the contact portion provided on the body 621.

[0343] Furthermore, the length of the conductive carrier has a certain degree of redundancy to form the deformable portion 613. Its redundant length is designed to cooperate with the displacement of the mounting portion 90 on the conductive unit 300, so that when the conductive carrier slides on the mounting portion 90, the deformable portion 613 can undergo telescopic deformation, that is, the deformable portion 613 can follow the reciprocating movement posture of the mounting portion 90 and synchronously move dynamically.

[0344] With this arrangement, there is no sliding friction between the external contact formed by the contact of the first connecting component 61 and the conductive unit 300 and the conductive unit 300. This avoids the generation of significant noise during the process of the external contact of the chip 20 sliding back and forth along the surface of the conductive unit 300. It also prevents the deformation of the external contact of the chip 20 caused by the long-term frictional movement between the external contact and the conductive unit 300, thereby improving the grounding stability of the chip 20. Furthermore, part of the first connecting component 61 is connected to the conductive unit 300, which can prevent the external contact from detaching from the surface of the conductive unit 300 and enhance the grounding stability of the chip 20.

[0345] On the basis of the above-mentioned embodiment, the conductive carrier in the embodiment of the present application includes a conductive portion and an insulating portion. The insulating portion wraps part of the conductive portion, and the parts of the conductive portion exposed from both ends of the insulating portion are respectively configured as a first contact portion 611 and a second contact portion 612. The first contact portion 611 is fixedly connected to the conductive unit 300, and the second contact portion 612 is electrically connected to the second connecting component 62.

[0346] Exemplarily, the conductive portion is configured as a conductive core or a conductive sheet, and the insulating portion is configured as an insulating layer wrapping the conductive core. For example, the conductive core includes a first end and a second end disposed oppositely, the insulating layer includes a middle portion of the conductive core, and the first end and the second end of the conductive core are exposed from the insulating layer, such that the first end of the conductive core is configured as a first contact portion 611, the second end of the conductive core is configured as a second contact portion 612, wherein the first contact portion 611 is connected to the side of the conductive unit 300, and the second contact portion 612 is electrically connected to the second connecting component 62.

[0347] It should be noted that, in order to improve the connection reliability between the second contact portion 612 and the second connecting component 62, the second connecting component 62 is provided with a third contact portion 623, and the third contact portion 623 is located on the body 624 of the second connecting component 62 and located close to the second contact portion 612. For example, the third contact portion 623 can be a conductive protrusion (conductive terminal) provided on the body 621, and the second contact portion 612 can be attached to and electrically connected to the conductive protrusion.

[0348] Furthermore, the entirety or at least a part of the second connecting component 62 is made of conductive material to satisfy the requirement that the grounding contact of the chip 20 is electrically connected to the conductive unit 300 through the first connecting component 61 and the second connecting component 62. For example, under the condition of ensuring safe use, except for the third contact portion 623 and the electrical contact portion 6221 provided on the extending portion 622 of the second connecting component 62, the remaining surfaces of the second connecting component 62 can be coated with an insulating material or provided with an insulating layer. This is to prevent the second connecting component 62 from coming into contact with other electrical components, thereby enhancing the reliability of the ground signal transmission.

[0349] The printing device provided by the embodiment of the present application also includes a communication component 200, and at least part of the communication component 200 is deformable. For example, the communication component 200 can be a cable or a crawler track. One end of the communication component 200 is connected to the mounting portion 90, and the other end is connected to the conductive unit 300. The middle part of the communication component 200 is deformable; an adapter board is provided in the mounting portion 90. The adapter board communicates with the control communication unit inside the conductive unit 300 through the communication component 200.

[0350] Further, the deformable portion 613 of the first connecting component 61 can be provided on the body 621 of the communication component 200, that is, the deformable portion 613 of the conductive carrier is attached to the communication component 200. With this arrangement, the first connecting component 61 can be appropriately restricted in the printing device, preventing the first connecting component 61 from interfering with or entangled with other internal components, thereby preventing the first connecting component 61 from being damaged.

[0351] As shown in Figures 85 and 86, in another embodiment of the present application, the first connecting component 61 is disposed on the second connecting component 62. The first connecting component 61 is configured as a contact piece that can move relative to the second connecting component 62, and the first connecting component 61 can move along the surface of the conductive unit 300.

[0352] As shown in Figure 87, the second connecting component 62 in this embodiment includes a third positioning portion 624 and a fourth positioning part 625. The third positioning part 624 and the fourth positioning part 625 may be an integral structure. The third positioning portion 624 is located above the fourth positioning portion 625 and extends horizontally along the second direction and the first direction. The third positioning portion 624 can be arranged parallel to the conductive unit 300. When the second connecting component 62 is mounted onto the mounting portion 90, the third positioning portion 624 can abut against the top surface of the mounting portion 90.

[0353] Continuing to refer to Figure 82, the mounting portion 90 is provided with a third support portion 993 that cooperates with the third positioning portion 624. The third support portion 993 may be the top surface of part of the housing. In the embodiment of the present application, the third supporting portion 993 is the partial top surface on the side close to the conductive unit 300. Along the first direction, the third supporting portion 993 is located on the side of the first supporting portion 991 away from the ink cartridge assembly. And along the third direction, the third supporting portion 993 protrudes from the first supporting portion 991, that is, the height where the third supporting portion 993 is located is greater than that of the first supporting portion 991.

[0354] The above-mentioned fourth positioning portion 625 is arranged obliquely below the third positioning portion 624, and along the third direction, one side of the fourth positioning portion 625 is connected to the bottom of the third positioning portion 624, and the connection position is located on the side of the third positioning portion 624 facing the ink cartridge assembly. The other side of the fourth positioning portion 625 extends obliquely downward along the first direction towards the side of the ink cartridge assembly. That is, the fourth positioning portion 625 can be configured as a positioning slope on the second connecting component 62.

[0355] Correspondingly, the mounting portion 90 is provided with a fourth supporting portion 994 that cooperates with the fourth positioning portion 625. Along the first direction, the fourth supporting portion 994 is located between the first supporting portion 991 and the third supporting portion 993, and the fourth supporting portion 994 may be a support slope formed on the top surface of the housing, and the support slope cooperates with the above-mentioned positioning slope.

[0356] It should be understood that when the above-mentioned second connecting component 62 is inserted into the accommodation cavity 995 of the housing, the third positioning portion 624 is in contact with the third supporting portion 993 and can at least restrict the position of the second connecting component 62 in the third direction. The fourth positioning portion 625 and the fourth supporting portion 994 are in contact with each other to at least restrict the position of the second connecting component 62 in the first direction.

[0357] Furthermore, in this embodiment, the second connecting component 62 further includes a first electrical connection portion 626 that abuts against the first supporting portion 991. The first electrical connection portion 626 is located on the side of the fourth positioning portion 625 away from the third positioning portion 624. One side of the first electrical connection portion 626 is connected to the fourth positioning portion 625, and the first electrical connection portion 626 extends horizontally along the first direction towards one side of the ink cartridge assembly.

[0358] For example, the first electrical connection portion 626 can be disposed in parallel with the third positioning portion 624; therefore, along the first direction, the third positioning portion 624 and the first electrical connection portion 626 are respectively disposed in parallel on both sides of the fourth positioning portion 625. They form a ladder-like structure or a Z-shaped structure.

[0359] It should be noted that the whole or at least part of the first electrical connection portion 626 is made of conductive material, and the first electrical connection portion 626 is used to electrically connect with the grounding contact 23 so that the ground signal in the conductive unit 300 passes through the first The connecting component 61, the third positioning part 624, the fourth positioning part 625, and the first electrical connection portion 626 are transmitted to the grounding contact 23 of the chip 20.

[0360] Based on the above embodiments, the second connecting component 62 in the embodiment of the present application includes an accommodating portion 627, and the accommodating portion 627 is provided above the third positioning portion 624 along the third direction; a mounting shaft 629 is provided in the accommodating portion 627. The first connecting component 61 is disposed on the mounting shaft 629, and the mounting shaft 629 is made of conductive material.

[0361] Further, at least a part of the first connecting component 61 has an electrical contact portion for rolling electrical connection with the conductive unit 300, so that the ground signal in the conductive unit 300 are transmitted to the grounding contact 23 of the chip 20 through the first connecting component 61, the mounting shaft 629, the third positioning portion 624, the fourth positioning portion 625 and the first electrical connection portion 626.

[0362] Specifically, the accommodating portion 627 is arranged in parallel above the third positioning portion 624, and in the first direction, the projections of the accommodating portion 627 and the conductive unit 300 at least partially overlap to ensure that the first connecting component 61 mounted on the accommodating portion 627 can be in contact with the conductive unit 300.

[0363] The accommodating portion 627 has an accommodating groove. The accommodating groove is strip-shaped, and its length extension direction is consistent with the extension direction of the conductive unit 300. The notch of the accommodating groove is set towards the conductive unit 300. A mounting shaft 629 is arranged in the accommodating groove. The axial direction of the mounting shaft 629 extends along the third direction. The first connecting component 61 is mounted on the mounting shaft 629 and can rotate relative to the mounting shaft 629.

[0364] At least a part of the first connecting component 61 has an electrical contact portion, and this electrical contact portion is in rolling electrical connection with the conductive unit 300. For example, the first connecting component 61 is configured as a conductive roller. The conductive roller is rotatably connected to the mounting shaft 629, and the outer peripheral surface of the conductive roller can come into contact with the conductive unit 300. That is, as the mounting portion 90 moves relative to the conductive unit 300, the conductive roller rotates continuously, enabling the outer peripheral surface at different positions to contact the conductive unit 300. In other words, part of the first connecting component 61 can move dynamically in synchronization with the reciprocating movement of the mounting portion 90 (the conductive roller rotates continuously).

[0365] With such an arrangement, there is no relative displacement or sliding friction between the external contact formed by the contact between the first connecting component 61 and the conductive unit 300 and the extending direction of the conductive unit 300. This avoids the generation of significant noise during the process of the external contact of the chip 20 sliding back and forth along the surface of the conductive unit 300. It also prevents the external contact of the chip 20 from being deformed due to heat generated by long-term frictional movement with the conductive unit 300, thereby improving the grounding stability of the chip 20. Moreover, since part of the first connecting component 61 is rotatably connected to the conductive unit 300, the situation where the external contact is detached from the surface of the conductive unit 300 due to wear is effectively reduced, further enhancing the grounding stability of the chip 20.

[0366] As shown in Figures 88 to 90, on the basis of the above-mentioned embodiment, the connection assembly in the embodiment of the present application further includes an auxiliary connecting component 63. The auxiliary connecting component 63 is used for electrically connecting the grounding contact 23 with the first electrical connection portion 626. With such an arrangement, the applicability and electrical connection reliability of the second connecting component 62 can be improved.

[0367] Specifically, the auxiliary connecting component 63 can be configured as a conductive wire or a conductive sheet. The chip 20 is arranged below the handle 11 of the ink cartridge, and a certain distance is maintained between the two in the third direction. Furthermore, the chip 20 is also located below the first electrical connection portion 626. The first electrical connection portion is disposed opposite to the handle 11 and partially overlaps with it.

[0368] For example, in one embodiment, the auxiliary connecting component 63 is configured as a conductive sheet. The conductive sheet is arranged between the chip 20 and the first electrical connection portion 626 and is used to electrically connect the grounding contact 23 of the chip to the first electrical connection portion 626. The conductive sheet extends in the third direction. The first end of the conductive sheet is connected to the grounding contact 23 of the chip 20, and the second end of the conductive sheet extends upward in the third direction. The second end of the conductive sheet extends to the position of the handle 11 and is electrically connected to the first electrical connection portion 626.

[0369] The second end of the conductive sheet is provided with a fourth contact portion 631 to form its contact part. The fourth contact portion 631 can be a conductive terminal arranged on the conductive sheet, and the conductive terminal is electrically connected to the first electrical connection portion 626. The fourth contact portion 631 partially overlaps with the handle 11 in the third direction. Exemplarily, the first projection plane is defined as the plane where the second direction and the third direction are located. Along the first direction, the projection of the fourth contact portion 631 on the first projection plane partially coincides with the projection of the handle 11 on the first projection plane.

[0370] As shown in Figures 91 to 95, in another embodiment, the auxiliary connecting component 63 is configured as a conductive plate. This conductive plate can be integrally manufactured with the substrate 21 of the chip 20. That is, this conductive plate is regarded as a part of the substrate 21. Along the third direction, a part of the substrate 21 can be extended to serve as the auxiliary connecting component 63.

[0371] Along the third direction, the top end of the conductive plate is located below the handle 11 and also below the first electrical connection portion 626. The grounding contact 23 and the fourth contact portion 631 can be arranged at the top end of the conductive plate and are located on both sides of the conductive plate. The fourth contact portion 631 is positioned below the handle 11 and is set close to the handle 11. The grounding contact 23 and the fourth contact portion 631 can be electrically connected through conductive traces or vias.

[0372] To enable the first electrical connection portion 626 to be electrically connected to the grounding contact 23 for the transmission of the ground signal, in the embodiment of this application, the second connecting component 62 further includes a second electrical connection portion 628. The second electrical connection portion 628 has a clearance space for the handle 11. Part of the second electrical connection portion 628 is electrically connected to the first electrical connection portion 626, and part of it is located below the handle 11 and electrically connected to the fourth contact portion 631. The fourth contact portion 631 is located below the handle 11, and they do not overlap. That is, along the first direction, the projection of the fourth contact portion 631 on the first projection plane does not coincide with the projection of the handle 11 on the first projection plane.

[0373] For example, the second electrical connection portion 628 is L-shaped and includes a first horizontal section and a first vertical section. The first horizontal section is arranged below the handle 11 and extends along the second direction. The first vertical section extends along the third direction and is arranged on one side of the handle 11 to avoid the handle 11. The first vertical section is connected to the first electrical connection portion 626.

[0374] It should be noted that the whole or at least a part of the auxiliary connecting component 63 is made of a conductive material to ensure that the grounding contact 23 of the chip 20 is electrically connected to the conductive unit 300 through the first connecting component 61, the second connecting component 62, and the auxiliary connecting component 63. For example, under the condition of ensuring safe use, in this embodiment, parts of the auxiliary connecting component 63 other than the fourth contact portion 631 are coated with an insulating material or provided with an insulating layer. This is to prevent the auxiliary connecting component 63 from coming into contact with other electrical components, thereby enhancing the reliability of the ground signal transmission.

[0375] It should be noted that in the embodiment of this application, the grounding contact 23 and the storage element 24 can be located on the same surface of the substrate 21, while the remaining contacts 22 and the grounding contact 23 are located on different surfaces of the substrate 21. The grounding contact 23 and the remaining contacts 22 can be electrically connected to the storage element 24 through conductive traces respectively.

[0376] For example, the substrate 21 includes a first surface and a second surface that are oppositely arranged. Each of the remaining contacts 22 is located on the first surface of the substrate 21, and the grounding contact 23 is located on the second surface of the substrate. The remaining contacts 22 have a first projection relative to the first surface of the substrate. The first projections of multiple remaining contacts 22 enclose a first area. The grounding contact 23 has a second projection on the second surface, and the second projection is located outside the first area. In the second direction (the Y - axis direction), the second projection and the first area overlap.
