Detailed implementation manners

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0045] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0046] In the present utility model, unless otherwise clearly defined and limited, the terms such as "installation", "connection", "fixation" and the like should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0047] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0048] In the above description, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0049] As described in the background art, the connection member and the contact pin adopt a point-to-point contact method, and the contact area is small. During the use of the consumable cartridge, when external environmental factors such as vibration and shaking occur, the connection member may be separated from the top of the contact pin, resulting in an unstable electrical connection between the connection member and the contact pin, and reducing the communication quality between the consumable cartridge and the printing device.

[0050] To solve the above problems, an embodiment of the present utility model provides a consumable cartridge, which increases the contact area between the connection member and the top of the contact pin. During the use of the consumable cartridge, when external environmental factors such as vibration and shaking occur, the connection member is not easily separated from the top of the contact pin, thereby providing the stability of the electrical connection between the two and improving the communication quality.

[0051] The following will describe in detail the consumable cartridge provided by the embodiment of the present utility model with reference to specific embodiments.

[0052] See Figure 1 and Figure 2 As shown, an embodiment of the present utility model provides a consumable cartridge, which is detachably installed in an installation unit provided in a printing device.

[0053] See Figure 3 As shown, the installation unit is provided with a contact pin group, and the contact pin group includes at least one contact pin 101. The contact pin 101 includes a first end 1011 and a second end 1012.

[0054] For better description of the consumable cartridge, as Figure 1 a coordinate system is established in: the length direction of the consumable cartridge is the X-axis direction, the width direction of the consumable cartridge is the Y-axis direction, and the height direction of the consumable cartridge is the Z-axis direction. Among them, the X-axis, Y-axis, and Z-axis are perpendicular to each other. In this example, the first direction is the direction indicated by the +Z axis, the second direction is the direction indicated by the +Y axis, and the third direction is the direction indicated by the +X axis. The angles between the first direction, the second direction, and the third direction can be 90°. In other possible implementation manners, the angles between the first direction, the second direction, and the third direction can be 80° to 100°, for example, they can be 80°, 85°, 90°, 95°, or 100°.

[0055] In the first direction, the second end 1012 is higher than the first end 1011, and the second end 1012 of the contact pin 101 is located on the top side of the contact pin 101.

[0056] A plurality of electrical contact parts are sequentially provided on the second end 1012 along the second direction, and adjacent electrical contact parts are separated by a spacer. Exemplarily, the plurality of electrical contact parts at least include a first electrical contact part 101a, a second electrical contact part 101c, and a third electrical contact part 101e. The spacer at least includes a first spacer 101b and a second spacer 101d. The first electrical contact part 101a and the second electrical contact part 101c are separated by the first spacer 101b, and the second electrical contact part 101c and the third electrical contact part 101e are separated by the second spacer 101d.

[0057] In the second direction, the first electrical contact part 101a, the first spacer 101b, the second electrical contact part 101c, the second spacer 101d, and the third electrical contact part 101e are sequentially arranged and connected to each other. The distances between the first electrical contact part 101a, the first spacer 101b, the second electrical contact part 101c, the second spacer 101d, and the third electrical contact part 101e and the consumable cartridge increase in sequence. The first electrical contact part 101a is closer to the body 11 of the consumable cartridge than the first spacer 101b.

[0058] It should be noted that in the first direction, the first electrical contact part 101a, the third electrical contact part 101e, and the second electrical contact part 101c have the same height, or any two of the first electrical contact part 101a, the second electrical contact part 101c, and the third electrical contact part 101e have the same height, or the first electrical contact part 101a, the second electrical contact part 101c, and the third electrical contact part 101e have different heights. In the first direction, each of the first electrical contact part 101a, the second electrical contact part 101c, and the third electrical contact part 101e is higher than the first spacer 101b and the second spacer 101d, and the heights of the first spacer 101b and the second spacer 101d can be the same or different.

[0059] The installation unit is provided with at least one installation position, and each installation position installs a consumable cartridge. In this embodiment, the installation unit is provided with 4 installation positions. Each consumable cartridge corresponds to a set of contact pins, and the set of contact pins includes at least a first set of contact pins and a second set of contact pins. Both the first set of contact pins and the second set of contact pins include at least one contact pin 101. It should be noted that the contact pin structures in the first set of contact pins and the second set of contact pins may be the same or different.

[0060] Embodiment 1

[0061] Refer to Figure 4 As shown, the consumable cartridge includes a body 11, a chip 12, and a connecting member 13.

[0062] A chip 12 is arranged on the body 11. The chip 12 includes a first terminal group facing the body 11 and a second terminal group facing away from the body 11.

[0063] Refer to Figure 5 and Figure 6 As shown, the chip 12 further includes a substrate 120. The substrate 120 has a first surface 1201 on the side facing the body 11 and a second surface 1202 on the side facing away from the body 11.

[0064] The first terminal group is located on the first surface 1201, and the first terminal group includes at least one first terminal 121. The first terminal 121 is electrically connected to the second end 1012 of the contact pin 101 of the first set of contact pins through the connecting member 13.

[0065] The second terminal group is located on the second surface 1202, and the second terminal group includes at least one second terminal 122. The second terminal 122 is electrically connected to the first end 1011 of the contact pin 101 of the second set of contact pins.

[0066] The chip 12 further includes a storage element 123. The storage element 123 may be located on the first surface 1201 or the second surface 1202.

[0067] The storage element 123 stores information of the chip 12. For example, the storage element 123 stores relevant information of the consumable cartridge, and the relevant information includes but is not limited to ink color information, ink volume information, manufacturing date of the consumable cartridge, identification information of the consumable cartridge, and program information used, etc.

[0068] Both the first terminal 121 and the second terminal 122 are electrically connected to the storage element 123. The first terminal 121 may be any terminal on the chip 12, and the second terminal 122 is one of the remaining terminals on the chip 12 after removing the first terminal 121.

[0069] In some examples, when the chip 12 includes a ground terminal, a power supply terminal, a reset terminal, a clock terminal, and a data terminal, the first terminal group includes a first terminal 121, and the first terminal 121 can be one of the ground terminal, the power supply terminal, the reset terminal, the clock terminal, and the data terminal. The second terminal group includes the remaining terminals except the first terminal in the first terminal group. It should be noted that the ground terminal is used to receive the ground potential; the power supply terminal is used to receive a power supply potential different from the ground potential (such as 3.6V or 3.3V), and the power supply is provided for the operation of the storage element 123 through this terminal; the reset terminal is used to reset the internal data of the storage element 123; the clock terminal is used to receive the clock signal; the data terminal is used to send or receive data signals, and is also used to detect whether a short circuit occurs between the data terminal and at least one of the clock terminal, the reset terminal, and the power supply terminal.

[0070] See Figure 7 As shown, the connector 13 includes an inner contact portion 13a and a plurality of outer contact portions 13b. The inner contact portion 13a is electrically connected to the first terminal 121, and the plurality of outer contact portions 13b are used to contact at least two of all the electrical contact portions and all the spacer portions. That is, the plurality of outer contact portions 13b are respectively in contact with at least two of the first electrical contact portion 101a, the first spacer portion 101b, the second electrical contact portion 101c, the second spacer portion 101d, and the third electrical contact portion 101e on the second end 1012 of the corresponding contact pin 101. With such a setting, the contact area between the outer contact portion 13b of the connector 13 and the contact pin 101 can be increased, so that when the consumable cartridge is in use, such as when external environmental factors such as vibration and shaking occur, the connector 13 is not easily separated from the top of the contact pin 101, thereby improving the stability of the electrical connection and the communication quality between the two.

[0071] It should be noted that the first end 1011 of the contact pin 101 in the first contact pin group electrically connected to the connector 13 does not contact the terminal on the chip 12, that is, it can be understood that the contact pin 101 in the first contact pin group is insulated from the surface of the second surface 1202 of the chip 12.

[0072] It should also be pointed out that the outer contact portion 13b and the second end 1012 of the contact pin 101 can be in a line-to-plane contact manner or a face-to-face contact manner.

[0073] Exemplarily, multiple outer contact portions 13b can respectively contact at least two of a first electrical contact portion 101a, a first spacer portion 101b, and a second electrical contact portion 101c on the second end 1012 of a corresponding contact pin 101. Alternatively, multiple outer contact portions 13b can also respectively contact at least two of a second electrical contact portion 101c, a second spacer portion 101d, and a third electrical contact portion 101e on the second end 1012 of a corresponding contact pin 101. Alternatively, multiple outer contact portions 13b can also respectively contact at least three of a first electrical contact portion 101a, a first spacer portion 101b, a second electrical contact portion 101c, a second spacer portion 101d, and a third electrical contact portion 101e on the second end 1012 of a corresponding contact pin 101. Alternatively, multiple outer contact portions 13b can also respectively contact a first spacer portion 101b and a second spacer portion 101d. Alternatively, a part of multiple outer contact portions 13b contacts at least one of a first electrical contact portion 101a, a second electrical contact portion 101c, and a third electrical contact portion 101e, and another part of multiple outer contact portions 13b contacts at least one of a first spacer portion 101b and a second spacer portion 101d.

[0074] In a possible implementation manner, the connecting member 13 has a first part and a second part. In the second direction, the second part at least partially protrudes from the main body 11, that is to say, in the second direction, the second part at least partially exposes the main body 11, and the first part is at least partially shielded by the chip 12.

[0075] The connecting member 13 respectively contacts a contact pin 101 in the first contact pin group and a first terminal 121. That is, the first part of the connecting member 13 is electrically connected to the first terminal 121; the second part of the connecting member 13 can contact the second end 1012 of the contact pin 101 in the first contact pin group, and the contact pin 101 in the first contact pin group corresponds to the first terminal 121.

[0076] Among them, the connecting member 13 is made of a conductive material. In some examples, the connecting member 13 is made of a flexible conductive material. The cross-section of the connecting member 13 is cylindrical.

[0077] The number of the connecting members 13 is equal to the number of the first terminals 121, that is to say, each connecting member 13 corresponds to a first terminal 121. In this embodiment, the number of the connecting members 13 is one, and the number of the first terminals 121 is also one.

[0078] The connecting member 13 and the chip 12 can be in contact or connection through welding, bonding, clamping, abutting or other means.

[0079] See Figure 7 As shown, the first part at least includes a base end portion 131. The base end portion 131 has a spiral structure.

[0080] The portion where the base end portion 131 is electrically connected to the first terminal 121 is the inner contact portion 13a. In this embodiment, when the chip 12 and the connecting member 13 are in the mounted state, the inner contact portion 13a abuts against the first terminal 121, and the inner contact portion 13a applies a abutting force toward the first terminal 121. With this arrangement, the first terminal 121 and the base end portion 131 can be stably contacted.

[0081] A first card slot 111 is provided on the body 11 (see Figure 5 shown), and the first card slot 111 can be formed by being recessed on the body 11. The base end portion 131 is stuck in the first card slot 111.

[0082] A plurality of outer contact portions 13b are provided on the second portion. Specifically, see Figure 7 shown, the second portion at least includes an arm portion 133. In the first direction, the arm portion 133 is higher than the second end 1012 of the contact pin 101. The base end portion 131 and the arm portion 133 are respectively connected to the connecting portion 132, and a plurality of outer contact portions 13b are located on the arm portion 133.

[0083] The connecting portion 132 includes a first connecting section 1321 and a second connecting section 1322.

[0084] The first connecting section 1321 is connected between the base end portion 131 and the arm portion 133.

[0085] A second card slot 112 is provided on the body 11 (see Figure 5 shown), and the second card slot 112 can be formed by being recessed on the body 11. The first connecting section 1321 is installed in the second card slot 112.

[0086] The second connecting section 1322 is connected to the arm portion 133. A latching projection 113 is provided on the body 11 (see Figure 5 shown), a bayonet 1323 is provided on the second connecting section 1322, and the second connecting section 1322 is latched on the latching projection 113 through the bayonet 1323.

[0087] In some examples, to ensure the safety of use, except for the base end portion 131 and the arm portion 133 on the connecting member 13, the remaining portion can be coated or provided with an insulating layer.

[0088] Furthermore, see Figure 7 shown, the arm portion 133 includes a first section 1331, a detour section 1332, and a second section 1333 that are connected in sequence.

[0089] The first section 1331 is connected to the first connecting section 1321. The detour section 1332 is arranged in a detour structure, and the detour structure can be understood as being composed of a plurality of bent sections.

[0090] In the first direction, the second section 1333 is closer to the second end 1012 of the stylus 101 than the first section 1331.

[0091] The second section 1333 is connected to the second connecting section 1322.

[0092] A plurality of outer contact portions 13b are located on the second section 1333. Exemplarily, at least two outer contact portions 13b are provided on the second section 1333, and the two outer contact portions 13b are arranged on the second section 1333 at intervals, or the two outer contact portions 13b may also be arranged on the second section 1333 continuously. Refer to Figure 8 As shown, when the consumable cartridge is loaded into the installation position of the installation unit, the two outer contact portions 13b of the connecting member 13 are respectively in contact with the first electrical contact portion 101a and the second electrical contact portion 101c of the second end 1012 of the corresponding stylus 101 in the first stylus group. It should be noted that the portion of the second section 1333 in contact with the first electrical contact portion 101a is one outer contact portion 13b.

[0102] For the rest of the structure, Embodiment 3 is the same as Embodiment 1.

[0103] Embodiment 4

[0104] The difference between the consumable cartridge in Embodiment 4 and the consumable cartridge in Embodiment 1 is that the arm portion 133 is increased with a second bending section 1335 and the second section 1333 is cancelled. Specifically, see Figure 12 As shown, in this embodiment, the arm portion 133 includes a first section 1331, a detour section 1332, and a second bending section 1335 that are connected in sequence. The second bending section 1335 extends toward the first spacer portion 101b or the second spacer portion 101d. The second bending section 1335 can extend along a non-linear path.

[0105] The connecting portion 132 only has a first connecting section 1321.

[0106] In the first direction, the second bent section 1335 is closer to the second end 1012 of the contact pin 101 than the first section 1331.

[0107] Wherein, in this embodiment, an outer contact portion 13b is provided on each of the detour section 1332 and the second bent section 1335 of the arm portion 133 of the connecting member 13, and the two outer contact portions 13b are arranged on the detour section 1332 and the second bent section 1335 in an interval manner or a continuous manner. Refer to Figure 13 As shown, when the consumable cartridge is loaded into the installation position of the installation unit, the two outer contact portions 13b of the connecting member 13 are respectively in contact with the third electrical contact portion 101e and the second interval portion 101d of the second end 1012 of the corresponding contact pin 101 in the first contact pin group. It should be noted that the portion of the detour section 1332 in contact with the third electrical contact portion 101e is one outer contact portion 13b, and the portion of the second bent section 1335 in contact with the second interval portion 101d is the other outer contact portion 13b.

[0108] Through the outer contact portion 13b on the second bent section 1335, it enters into the second interval portion 101d, and this outer contact portion 13b abuts against the second interval portion 101d. The second interval portion 101d can restrict the movement range of this outer contact portion 13b, and can effectively avoid the situation that due to the lack of restraint of the connecting member, due to external environmental factors such as vibration and shaking, the top contact of the connecting member with the corresponding contact pin is misaligned, resulting in the chip being burned or the printing device not recognizing the machine (terminal short circuit). Thus, the safety of chip use can be greatly improved.

[0109] In other embodiments, an outer contact portion 13b is provided on each of the detour section 1332 and the second bent section 1335 of the arm portion 133 of the connecting member 13, and the two outer contact portions 13b are arranged on the detour section 1332 and the second bent section 1335 in an interval manner. When the consumable cartridge is loaded into the installation position of the installation unit, the two outer contact portions 13b of the connecting member 13 are respectively in contact with the second electrical contact portion 101c and the first interval portion 101b of the second end 1012 of the corresponding contact pin 101 in the first contact pin group. It should be noted that the portion of the detour section 1332 in contact with the second electrical contact portion 101c is one outer contact portion 13b, and the portion of the second bent section 1335 in contact with the first interval portion 101b is the other outer contact portion 13b.

[0110] For the structures of the remaining parts, Embodiment 4 is the same as Embodiment 1.
