Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a chip and ink cartridge. Background Technology

[0002] Ink cartridges are components in inkjet printers used to store printing consumables and are an essential part of the printer. Ink cartridges are removably installed in the printer's mounting section, supplying printing consumables to the printer and enabling it to perform normal printing operations.

[0003] In related technologies, ink cartridges are equipped with chips, and the terminals of the chips are located in the same plane.

[0004] However, when ink, dust, or oil comes into contact with the chip surface, it may cause a short circuit between the terminals, affecting the normal recognition of the ink cartridge. Utility Model Content

[0005] This utility model provides a chip and ink cartridge to solve the problem that when ink, dust or oil comes into contact with the chip surface, it may cause a short circuit between the terminals, affecting the normal recognition of the ink cartridge.

[0006] In a first aspect, embodiments of the present invention provide a chip disposed on the container of an ink cartridge, the ink cartridge being used in a printing device, the printing device including a plurality of contact pins, the chip being in contact with the contact pins, including:

[0007] A substrate having a first surface and a second surface, the first surface being disposed on the side of the substrate away from the container body, the second surface having an angle greater than 0° and less than 90° with the length direction of the ink cartridge, and the second surface being configured to be visible from the side of the substrate close to the container body.

[0008] A terminal group, the terminal group including a first terminal and a second terminal, the first terminal being disposed on a first surface and the second terminal being disposed on a second surface.

[0009] In one possible implementation, the second surface has a pushing portion on one side of the chip in the width direction, and the second surface and the pushing portion form a groove. In the width direction of the chip, the size of the pushing portion at the end near the container body is larger than the size of the pushing portion at the end away from the container body.

[0010] In one possible implementation, the pushing part has a pushing surface on the side facing the groove, and the pushing surface and the second surface extend in the same direction.

[0011] In one possible implementation, the extension direction of the pushing surface is parallel to the extension direction of the second surface.

[0012] In one possible implementation, in the height direction of the chip, a guide portion is provided at the bottom of the push portion, the guide portion having a guide surface for guiding the stylus into the groove.

[0013] In one possible implementation, the groove has a dimension of 0.3 mm or greater in the width direction of the chip.

[0014] In one possible implementation, the angle between the second surface and the length direction of the ink cartridge is greater than 5° and less than 30°.

[0015] In one possible implementation, the projection of the first terminal in the height direction of the chip is a first projection, the projection of the second terminal in the height direction of the chip is a second projection, and the first projection and the second projection are spaced apart in the thickness direction of the chip.

[0016] In one possible implementation, the first terminal includes a data terminal, a reset terminal, a clock terminal, or a power supply terminal; the second terminal includes a ground terminal.

[0017] Secondly, this utility model embodiment provides an ink cartridge, including a container body and the chip described in the first aspect;

[0018] The chip is disposed on the front end face of the container.

[0019] This utility model embodiment provides a chip and an ink cartridge. The angle between the second surface of the substrate and the thickness direction of the chip is greater than 0° and less than 90°. The second surface is constructed so that it can be observed from the side of the substrate near the container. The second terminal is disposed on the second surface, which can prevent the second terminal from coming into contact with ink, dust or oil and causing a short circuit between it and the terminal on the first surface. This can ensure conductivity and signal transmission, and thus ensure the normal recognition of the ink cartridge.

[0020] By setting the second terminal on the second surface, the second surface is hidden when the chip is installed on the cartridge container, which can prevent the second terminal on the second surface from being physically damaged (scratched or bent), thus protecting the chip.

[0021] By placing the second terminal on the second surface, it is possible to prevent the second terminal from coming into contact with other metal parts or conductive materials and causing a short circuit, thereby protecting the chip from damage. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] As described in the background section, when ink, dust, or oil comes into contact with the chip surface, it may cause a short circuit between the terminals, affecting the normal recognition of the ink cartridge. Research has found that this problem occurs because the chip's terminals are located in the same plane. When ink, dust, or oil comes into contact with the chip surface, it may cause a short circuit between the terminals, affecting the normal recognition of the ink cartridge.

[0042] To address the aforementioned issues, this invention provides a chip and ink cartridge. By placing the second terminal on a second surface of the substrate, which is different from the first surface where the first terminal is located, the second surface can be observed from the side of the substrate close to the container, but not from the side of the substrate away from the container. The second terminal is located on a different surface from the other terminals, which can prevent the second terminal from coming into contact with ink, dust, or oil, thus avoiding short circuits between the second terminal and the other terminals. This ensures conductivity and signal transmission, thereby guaranteeing the normal recognition of the ink cartridge.

[0043] The chip and ink cartridge provided in the embodiments of this utility model will be described in detail below with reference to specific examples.

[0044] See Figure 1 As shown, the length direction of ink cartridge 100 is defined as the X direction, the width direction of ink cartridge 100 is defined as the Y direction, and the height direction of ink cartridge 100 is defined as the Z direction. The X, Y, and Z directions are perpendicular to each other.

[0045] See Figure 2 and Figure 3 As shown, this embodiment of the present invention provides a chip 10, which is applied to an ink cartridge 100. The ink cartridge 100 includes a container body 20 and the chip 10. The container body 20 includes a reservoir for storing ink and an ink outlet for ink flow. The chip 10 is disposed on the container body 20 of the ink cartridge 100, and the chip 10 is located on one side of the container body 20 along the length direction of the ink cartridge 100.

[0046] The top of container 20 is located on the +Z side. The bottom of container 20 is located on the -Z side.

[0047] The container body 20 has a front end face on one side in the +X direction.

[0048] The container body 20 may include an adapter and a container body, with the container body mounted on the adapter and the chip 10 disposed on the adapter. In other embodiments, the container body 20 may not have an adapter, that is, the container body 20 may only include the container body.

[0049] In this embodiment, the chip 10 can be parallel to the front end face. The thickness direction of the chip 10 is the same as the length direction of the ink cartridge 100, the width direction of the chip 10 is the same as the width direction of the ink cartridge 100, and the height direction of the chip 10 is the same as the height direction of the ink cartridge 100.

[0050] In other embodiments, chip 10 may intersect with the front end face. The thickness direction of chip 10 intersects with the length direction of ink cartridge 100. The width direction of chip 10 is the same as the width direction of ink cartridge 100. The height direction of chip 10 intersects with the height direction of ink cartridge 100.

[0051] Alternatively, in other embodiments, chip 10 may intersect with the front end face. The thickness direction of chip 10 intersects with the length direction of ink cartridge 100. The width direction of chip 10 intersects with the width direction of ink cartridge 100. The height direction of chip 10 is the same as the height direction of ink cartridge 100.

[0052] Ink cartridge 100 is used in printing devices. See also Figure 4 As shown, the printing device includes a mounting section 200, which includes four mounting positions 201. Four ink cartridges 100 are sequentially mounted in the four mounting positions 201 along the width direction of the ink cartridges 100. Each mounting position 201 is provided with a stylus holder 202 and five stylus pins 203. The stylus holder 202 is provided with multiple stylus slots, and each stylus pin 203 is mounted in one stylus slot. The chip 10 of the ink cartridge 100 contacts the stylus pin 203 in the corresponding mounting position 201, and the chip 10 can communicate with the stylus pins 203 of the printing device.

[0053] The contact pin 203 is made of metal. Electrical connection between the chip 10 and the contact pin 203 can be achieved by contacting either side of the terminal on the chip 10.

[0054] The ink cartridge 100 can be inserted into the mounting part 200 along the height direction of the ink cartridge 100, or removed from the mounting part 200 along the height direction of the ink cartridge 100.

[0055] In one possible implementation, see Figure 5a As shown, chip 10 includes substrate 11. Substrate 11 is square.

[0056] See Figures 5a to 7 As shown, the substrate 11 may have a first surface 11a, a second surface 11b, and a third surface 11c. The first surface 11a is disposed on the side of the substrate 11 away from the container body 20, and the third surface 11c is disposed on the side of the substrate 11 close to the container body 20. The first surface 11a is perpendicular to the thickness direction of the chip 10, and the first surface 11a and the third surface 11c may be parallel to each other.

[0057] The angle between the second surface 11b and the length direction of the ink cartridge 100 is α (see...). Figure 9 (As shown). a is greater than 0° and less than 90°.

[0058] See Figure 6 and Figure 7 As shown, the second surface 11b is configured to be visible from the side of the substrate 11 near the container body 20, that is, the second surface 11b can be observed when the substrate 11 is viewed along the +X direction.

[0059] See Figure 8 and Figure 9 As shown, when observing the substrate 11 along the -X direction, the second surface 11b cannot be observed.

[0060] Chip 10 also includes a terminal block. See [link / reference] Figures 5a to 7 As shown, the terminal group includes a first terminal 12 and a second terminal 13.

[0061] The number of first terminals 12 can be one or more. The number of second terminals 13 can be one or more.

[0062] The first terminal 12 can be disposed on the first surface 11a, and the second terminal 13 can be disposed on the second surface 11b. The first terminal 12 and the second terminal 13 are disposed on different surfaces, which can prevent the second terminal 13 from coming into contact with ink, dust or oil and causing a short circuit between it and the terminal on the first surface 11a, thereby ensuring conductivity and signal transmission, and thus ensuring the normal recognition of the ink cartridge 100.

[0063] The second terminal 13 is disposed on the second surface 11b. When the chip 10 is installed on the container body 20 of the ink cartridge 100, the second surface 11b is hidden, which can prevent the second terminal 13 on the second surface 11b from being physically damaged (scratched or bent), thereby protecting the chip 10.

[0064] By setting the second terminal 13 on the second surface 11b, it is possible to prevent the second terminal 13 from coming into contact with other metal parts or conductive materials and causing a short circuit, thereby protecting the chip 10 from damage.

[0065] It should be noted that the first terminal 12 and the second terminal 13 are electrically connected to a contact pin 203 of the printing device, respectively.

[0066] The chip 10 also includes a memory 14. The memory 14 is disposed on the third surface 11c of the substrate 11. The memory 14 is used to store information of the chip 10, such as manufacturer information, ink volume information, ink cartridge 100 category information, ink color, etc.

[0067] In one possible implementation, the angle between the second surface 11b and the length direction of the ink cartridge 100 is greater than 5° and less than 30°, that is, 'a' is greater than 5° and less than 30°. For example, the value of 'a' can be 5.1°, 5.5°, 6°, 10°, 15°, 20°, 25°, or 29°, etc. Of course, 'a' can also be other values, and those skilled in the art can choose according to their needs; this embodiment does not limit this.

[0068] Compared to a being less than or equal to 5°, making a greater than 5° makes it less likely for contaminants on the first surface 11a to contaminate the second terminal 13.

[0069] Compared to a being greater than or equal to 30°, making a less than 30° allows for better contact between the contact pin 203 and the second terminal 13, and makes it easier for the contact pin 203 to spring back to its original shape after being removed from the second terminal 13.

[0070] In one possible implementation, see Figure 5a and Figure 5bAs shown, a pushing part 111 is provided on one side of the second surface 11b in the width direction of the chip 10, and the second surface 11b and the pushing part 111 form a groove 112. In the width direction of the chip 10, the size of the end of the pushing part 111 near the container body 20 is larger than the size of the end of the pushing part 111 away from the container body 20, that is, the size of the -X direction end of the pushing part is larger than the size of the +X direction end of the pushing part. With this configuration, when the ink cartridge 100 is installed in the mounting part 200 of the printing device, the stylus 203 can be inserted into the groove 112, and the -X direction end of the pushing part 111 can squeeze the stylus 203, so that the -X direction end of the stylus 203 is slightly bent towards the second surface 11b relative to the +X direction end and then contacts the second terminal 13.

[0071] In this embodiment, the second surface 11b is disposed on one side of the pushing part 111 in the -Y direction. In other embodiments, the second surface 11b may be disposed on one side of the pushing part 111 in the +Y direction.

[0072] The groove 112 penetrates the side of the substrate 11 away from the container body 20. At the same time, the groove 112 may penetrate the side of the substrate 11 near the container body 20, or it may not penetrate the side of the substrate 11 near the container body 20.

[0073] In some examples, the dimension of the contact pin 203 in the width direction of the chip 10 can be 0.3 mm. The dimension of the groove 112 in the width direction of the chip 10 is b. b is greater than or equal to 0.3 mm. For example, the value of b can be 0.3 mm, 0.4 mm, 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, or 2 mm, etc. Of course, b can also be other values, and those skilled in the art can choose according to their needs. This embodiment does not limit this. If b is less than 0.3 mm, the contact pin 203 will not be able to be inserted into the groove 112, making it impossible for the contact pin 203 to be electrically connected to the second terminal 13. Preferably, b is slightly greater than 0.3 mm. By limiting the value of b, the contact pin 203 can be inserted into the groove 112, and the pushing part 111 can squeeze the contact pin 203, causing the contact pin 203 to bend and contact the second terminal 13, thereby maintaining the electrical connection.

[0074] A pushing surface 1111 is provided on the side of the pushing part 111 near the groove 112, and the pushing surface 1111 and the second surface 11b extend in the same direction. In this embodiment, both the pushing surface 1111 and the second surface 11b extend from the +X and +Y direction ends of the chip 10 to the -X and -Y direction ends. With this configuration, when the contact pin 203 can be inserted into the groove 112, the pushing surface 1111 can squeeze the contact pin 203 to bend towards the second surface 11b, so that the contact pin 203 contacts the second terminal 13 after bending.

[0075] In this embodiment, the pushing surface 1111 is disposed opposite to the second surface 11b in the width direction of the chip 10.

[0076] It should be noted that in this embodiment, the second terminal 13 on the second surface 11b abuts against the side of the contact pin 203.

[0077] When the -X direction end of the second surface 11b is closer to the -Y direction side than the +X direction end, the pushing surface 1111 is located on the +Y direction side of the second surface 11b. One end of both the pushing surface 1111 and one end of the second surface 11b extend from the first surface 11a towards the -X and -Y directions and towards the third surface 11c. The end of the pushing surface 1111 near the first surface 11a is located on the +Y direction side of the end of the pushing surface 1111 near the third surface 11c, and the end of the second surface 11b near the first surface 11a is located on the +Y direction side of the end of the second surface 11b near the third surface 11c. With this configuration, when contaminants adhere to the second surface 11b, the contaminants will flow away along the groove 112 and the second surface 11b towards the -X and -Z directions, preventing the first terminal 12 and the second terminal 13 from being oxidized or corroded.

[0078] In some examples, a connecting surface 11e is provided between the pushing surface 1111 and the second surface 11b.

[0079] In other embodiments, the second terminal 13 may also be disposed on the connecting surface 11e, and the connecting surface 11e and the first surface 11a are located on different surfaces, which can prevent the second terminal 13 from coming into contact with ink, dust or oil and causing a short circuit between it and the terminal on the first surface 11a.

[0080] In some examples, the extension direction of the pushing surface 1111 may be parallel to the extension direction of the second surface 11b.

[0081] In one possible implementation, see Figure 5a and Figure 5b As shown, in the height direction of the chip 10, a guide portion 113 is provided at the bottom of the pushing portion 111, and the guide portion 113 has a guide surface 1131 for guiding the stylus 203 into the groove 112. With this configuration, when the ink cartridge is installed into the mounting portion of the printer along the -Z direction, the guide surface 1131 can guide the stylus 203 into the groove 112, thereby ensuring that when the ink cartridge 100 is installed in the mounting portion 200 of the printer, the stylus 203 can be inserted into the groove 112.

[0082] When the ink cartridge 100 is inserted into the mounting part 200 along the -Z direction, the guide part 113 of the chip 10 contacts the contact pin 203 before the push part 111.

[0083] The guide surface 1131 has a second surface 11b and a mating surface 11d on one side in the -Y direction. The mating surface 11d and the second surface 11b are located in different surfaces. When the ink cartridge is inserted into the mounting part of the printing device along the -Z direction, the guide surface 1131 and the mating surface 11d can guide the stylus 203 into the groove 112.

[0084] The dimension of the guide surface 1131 near the push part 111 and the second surface 11b in the width direction of the chip 10 is smaller than the dimension of the guide surface 1131 away from the push part 111 and the second surface 11b in the width direction of the chip 10.

[0085] The bottom part of the groove 112 that first engages with the stylus 203 has a larger dimension in the width direction of the chip 10 than the top part of the groove 112 in the width direction of the chip 10, so the stylus 203 can smoothly enter the groove 112.

[0086] The end of the groove 112 in the +Z direction is the top end of the groove 112; the end of the groove 112 in the -Z direction is the bottom end of the groove 112.

[0087] In one possible implementation, the projection of the first terminal 12 in the height direction of the chip 10 is the first projection, and the projection of the second terminal 13 in the height direction of the chip 10 is the second projection. The first projection and the second projection are spaced apart in the thickness direction of the chip 10. This arrangement allows the first terminal 12 and the second terminal 13 to be positioned differently in the thickness direction of the chip 10, making it less likely for the first terminal 12 and the second terminal 13 to short-circuit.

[0088] The first projection and the second projection can be located in a virtual plane defined by the X and Y directions, which is perpendicular to the height direction of the chip 10.

[0089] In one possible implementation, chip 10 includes a data terminal, a reset terminal, a clock terminal, a power supply terminal, and a ground terminal.

[0090] The data terminal can be used to send or receive data signals.

[0091] The clock terminal can be used to receive clock signals.

[0092] The power supply terminal can be used to receive a power supply potential different from the ground potential (such as 3.6V or 3.3V), through which power is supplied for the operation of the memory 14.

[0093] The reset terminal can be used to reset the data inside memory 14.

[0094] The grounding terminal can be used to receive grounding potential.

[0095] The second terminal 13 may include one of the data terminal, reset terminal, clock terminal, power supply terminal, and ground terminal. The first terminal 12 may include one or more of the data terminal, reset terminal, clock terminal, power supply terminal, and ground terminal excluding the second terminal 13.

[0096] In some examples, the first terminal 12 includes a data terminal, a reset terminal, a clock terminal, or a power terminal. Four first terminals 12 are disposed on the first surface 11a of the substrate 11, and the four first terminals 12 include a data terminal, a reset terminal, a clock terminal, and a power terminal.

[0097] The four first terminals 12 can be arranged in multiple rows along the height direction of the chip.

[0098] A second terminal 13 is provided on the second surface 11b of the substrate 11, and the second terminal 13 includes a ground terminal. With this configuration, the ground terminal is less likely to come into contact with ink, dust or oil, which could cause a short circuit with other terminals.

[0099] This utility model provides an ink cartridge 100, which includes a container body 20 and a chip 10; the chip 10 is disposed on the front end surface of the container body 20.

[0100] The chip 10 in this embodiment has the same structure as the chip 10 provided in any of the above embodiments and can bring the same or similar technical effects. It will not be described in detail here, but can be referred to the description of the above embodiments.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
