[0016] The auxiliary contact portion is located in the second area; or, there are multiple auxiliary contact portions, some of which are located in the second area, and another part of which are located in the first area.

[0017] In one possible embodiment, multiple groups of terminals and at least one auxiliary contact terminal are provided on the substrate, and the multiple groups of terminals include at least one first terminal and multiple second terminals.

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0047] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0048] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0049] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. 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 can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0050] As described in the background technology, during the installation and disassembly of the consumables box, due to reasons such as improper installation or violent installation, the stylus in the printing device frequently rubs against the surface of the detection line segment, and the detection line segment is unable to connect to the ground terminal due to wear, resulting in the detection line segment being unable to suppress the chip from burning or the chip function not being able to function normally due to a short circuit between the terminals. The inventors have found that the reason for this problem is that the position of the detection line segment on the chip is within the movement range of the stylus of the printing device, causing the stylus in the printing device to frequently rub against the surface of the detection line segment, and the detection line segment is unable to connect to the ground terminal due to wear, resulting in the detection line segment being unable to suppress the chip from burning or the chip function not being able to function normally due to a short circuit between the terminals.

[0051] In order to solve the above problems, the embodiment of the present invention provides a chip and consumables box, in which the position of the auxiliary part on the chip is outside the movement range of the stylus of the printing device, which can effectively avoid the problem in the prior art that the stylus frequently rubs against the surface of the auxiliary part and causes serious damage to the auxiliary part due to improper installation or violent installation during the installation and disassembly of the consumables box. The auxiliary part can thus suppress the short circuit between the second contact parts, which may cause the chip to be burned or the chip function to fail to function normally.

[0052] The chip and consumables box provided by the embodiment of the utility model are described in detail below with reference to specific embodiments.

[0053] Example 1

[0054] See also Figure 1a and 1b As shown, an embodiment of the present invention provides a consumables box that can be detachably mounted in a mounting unit of a printing device. The mounting unit of the printing device includes a stylus assembly, which includes a plurality of first stylus pins 301 and at least one second stylus pin 302.

[0055] See also Figure 1c and Figure 2 As shown, an embodiment of the present invention provides a chip 100 mounted on a body 200 of a consumables box.

[0056] The length direction of the chip 100 is a first direction, which is either the +X axis direction or the -X axis direction. The height direction of the chip 100 is a second direction, which is either the +Y axis direction or the -Y axis direction. The thickness direction of the chip 100 is a third direction, which is either the +Z axis direction or the -Z axis direction. The first, second, and third directions are perpendicular to each other.

[0057] In some examples, the installation direction of the consumables cartridge in the printing device is the -Y axis direction.

[0058] See also Figure 2 and Figure 3 As shown, the chip 100 includes a substrate 10. The substrate 10 has a first side 10a and a second side 10b in a thickness direction of the chip 100.

[0059] The chip 100 includes a plurality of contacts disposed on the first side 10 a of the substrate 10 .

[0060] The plurality of contact portions include at least one first contact portion 111 and a plurality of second contact portions 121. Exemplarily, the plurality of contact portions include one first contact portion 111 and three second contact portions 121.

[0061] When the consumables cartridge is installed in the installation unit of the printing device, the first contact portion 111 and the second contact portion 121 respectively correspond to one first contact pin 301. The first contact portion 111 and the second contact portion 121 respectively contact the corresponding first contact pin 301.

[0062] In some examples, the first contact portion 111 may be a ground contact portion, which is used to receive a ground signal. The three second contacts 121 are respectively a data contact portion, a clock contact portion, and a power contact portion; the data contact portion is used to send or receive a data signal; the clock contact portion is used to receive a clock signal; and the power contact portion is used to receive a power signal.

[0063] The chip 100 includes auxiliary contact portions 131 . The auxiliary contact portions 131 are arranged on the first side 10 a of the substrate 10 .

[0064] When the consumables cartridge is installed in the installation unit of the printing device, the auxiliary contact portion 131 corresponds to one second contact pin 302 , and the auxiliary contact portion 131 contacts the second contact pin 302 .

[0065] Along the first direction, that is, along the length direction of the chip 100 , the auxiliary contact portion 131 is closer to the second contact portion 121 than the first contact portion 111 .

[0066] At least some of the second contact portions 121 among the plurality of second contact portions 121 are arranged around the auxiliary contact portion 131 .

[0067] Exemplarily, the chip 100 includes three second contact portions 121 , and the three second contact portions 121 are arranged around the auxiliary contact portion 131 . In other embodiments, the chip 100 includes three second contact portions 121 , and two of the three second contact portions 121 are arranged around the auxiliary contact portion 131 .

[0068] The chip 100 includes an auxiliary member 14 . Exemplarily, the auxiliary member 14 is disposed on the first side 10 a of the substrate 10 .

[0069] The auxiliary member 14 electrically connects the auxiliary contact portion 131 and at least one first contact portion 111. Exemplarily, the auxiliary member 14 electrically connects the auxiliary contact portion 131 and one of the first contact portions 111, so that when the consumable cartridge is installed in the installation unit of the printing device, the level signal of the auxiliary contact portion 131 is reduced to a low-level signal.

[0070] Exemplarily, the low-level signal is a ground-level signal.

[0071] At least some of the multiple second contact portions 121 are arranged around the auxiliary contact portion 131, and the auxiliary part 14 electrically connects the auxiliary contact portion 131 and at least one first contact portion 111. When the consumable box is loaded into the printing device, the conductive material adhered to the consumable box moves to the surface of the chip 100 under the action of gravity, and can be intercepted by the first contact pin and the second contact pin. The conductive material is collected or retained between the auxiliary contact portion 131 and the second contact portion 121, so that the short-circuit current between the multiple second contact portions 121 can be guided to the first contact portion 111 by the auxiliary contact portion 131, that is, the level signal of the multiple short-circuited second contact portions 121 is quickly reduced to a low-level signal, thereby ensuring the safety of each second contact portion 121 and effectively ensuring that the chip or printer is not burned; at the same time, when a short circuit occurs between the multiple second contact portions 121, it also helps to be quickly detected and identified, thereby improving the safety and stability of the chip.

[0072] Along the second direction, i.e., along the height of the chip 100, the projection of the auxiliary member 14 does not overlap with the projection of each of the multiple contact portions, nor does it overlap with the projection of the auxiliary contact portion 131. For example, along the second direction, i.e., along the height of the chip 100, the projection of the auxiliary member 14 does not overlap with the projection of the first contact portion 111, the projection of the auxiliary member 14 does not overlap with the projection of each of the second contact portions 121, and the projection of the auxiliary member 14 does not overlap with the projection of the auxiliary contact portion 131. This arrangement ensures that the auxiliary member 14 is positioned on the chip 100 outside the range of motion of the stylus of the printing device. This effectively prevents serious damage to the auxiliary member 14 caused by frequent friction between the stylus and the surface during installation and removal of the consumable cartridge, due to improper or rough installation. This ensures that the auxiliary member 14 can prevent short circuits between the multiple second contact portions 121, which could damage the chip 100 or malfunction the chip 100. At the same time, it ensures the normal function of the chip 100 and the stability of communication with the printing device, extends the service life of the chip 100, and saves users' usage costs.

[0073] It should be noted that, in other embodiments, for example, a conductive member (not shown in the figure) is provided on the main body 200 of the consumables box, the first contact portion 111 is provided on the second side 10b of the substrate 10, one end of the conductive member is in electrical contact with the first contact portion 111, and the other end of the conductive member is in contact with the corresponding first contact pin 301, and the auxiliary member 14 is provided on the first side 10a of the substrate 10, and the auxiliary member 14 is electrically connected to the auxiliary contact portion 131 and the conductive member. Alternatively, a conductive member (not shown in the figure) is provided on the main body 200 of the consumables box, the first contact portion 111 is provided on the second side 10b of the substrate 10, one end of the conductive member is in electrical contact with the first contact portion 111, and the other end of the conductive member is in contact with the corresponding first contact pin 301, a portion of the auxiliary member 14 is provided on the second side 10b of the substrate 10 for electrical contact with the first contact portion 111, and another portion of the auxiliary member 14 extends to the first side 10a of the substrate 10 for electrical contact with the auxiliary contact portion 131.

[0074] In one possible implementation, see Figure 3 As shown, a storage element 15 is provided on the substrate 10. Specifically, the storage element 15 is provided on the second side 10b of the substrate 10. The storage element 15 stores information of the chip 100, for example, the storage element 15 stores information such as manufacturer information, ink volume information, consumable cartridge type information, ink color, etc.

[0075] The plurality of contacts are electrically connected to the memory element 15 , respectively, while the auxiliary contact 131 is not electrically connected to the memory element 15 . That is, the first contact 111 and the second contact 121 are electrically connected to the memory element 15 , respectively, while the auxiliary contact 131 is not electrically connected to the memory element 15 .

[0076] In a possible implementation, multiple groups of terminals and at least one auxiliary contact terminal 13 are provided on the substrate 10 .

[0077] The plurality of terminal groups include at least one first terminal 11 and a plurality of second terminals 12. The first terminal 11 contacts the corresponding first contact pin 301 to form a first contact portion 111, and the second terminal 12 contacts the corresponding first contact pin 301 to form a second contact portion 121.

[0078] Exemplarily, the plurality of terminal groups include a first terminal 11 and three second terminals 12, each of which is spaced apart on the substrate 10. When the consumable cartridge is installed in the mounting unit of the printing device, the first terminal 11 and the second terminal 12 each correspond to a first contact pin. The first terminal 11 and the second terminal 12 each contact the corresponding first contact pin.

[0079] The first terminal 11 may be a ground terminal, the first contact pin 301 corresponding to the ground terminal is a ground contact pin, and the portion where the ground terminal contacts the ground contact pin forms a ground contact portion.

[0080] The three second terminals 12 are respectively a data terminal, a clock terminal, and a power terminal. The first contact pin 301 corresponding to the data terminal is a data contact pin, and the portion where the data terminal contacts the data contact pin forms a data contact portion. The first contact pin 301 corresponding to the clock terminal is a clock contact pin, and the portion where the clock terminal contacts the clock contact pin forms a clock contact portion. The first contact pin 301 corresponding to the power terminal is a power contact pin, and the portion where the power terminal contacts the power contact pin forms a power contact portion.

[0081] The portion where the auxiliary contact terminal 13 contacts the second contact pin 302 forms an auxiliary contact portion 131. For example, the second contact pin corresponding to the auxiliary contact terminal 13 is a reset contact pin, and the portion where the auxiliary contact terminal 13 contacts the reset contact pin forms the auxiliary contact portion 131. It should be noted that the chip 100 in the embodiment of the present application does not have a reset terminal. The reset function of the chip 100 is implemented by the reset circuit within the storage element 15 in conjunction with a corresponding program.

[0082] In one example, the first terminal 11 is electrically connected to a ground pin in the storage element 15, and the auxiliary contact terminal 13 can also be electrically connected to the ground pin of the storage element 15. During use of the consumable cartridge, if the first terminal 11 is accidentally damaged or malfunctions, the auxiliary contact terminal 13 can still detect and identify a short circuit between the plurality of second terminals 12, thereby ensuring safe use of the chip and normal functioning.

[0083] The material of the auxiliary member 14 and the material of the auxiliary contact terminal 13 are the same as the material of the first terminal 11 .

[0084] Furthermore, the level of the signal received by the first terminal 11 from the printing device is lower than the level of the signal received by the second terminal 12 from the printing device. Because the auxiliary contact terminal 13 is electrically connected to the first terminal 11 via the auxiliary member 14, the level of the signal received by the auxiliary contact terminal 13 from the first terminal 11 is also lower than the level of the signal received by the second terminal 12. This arrangement allows the auxiliary contact terminal 13 to quickly reduce the level of the signal at the short-circuited second terminals 12 when conductive material accumulates or accumulates between the auxiliary contact terminal 13 and the multiple second terminals 12.

[0085] For example, the first terminal 11 can be a ground terminal, and the three second terminals 12 are respectively a data terminal, a clock terminal, and a power terminal. When the consumable cartridge is installed in the printing device, the first terminal 11 contacts the first contact pin, the auxiliary contact terminal 13 contacts the second contact pin, and the second terminal 12 contacts the first contact pin. The level signals received by the first terminal 11 and the auxiliary contact terminal 13 are both ground signals, and the level signals of the first terminal 11 and the auxiliary contact terminal 13 are lower than the level signal of the second terminal 12.

[0086] In one possible embodiment, the first contact portion 111 is further away from the second contact portion 121 than the auxiliary contact portion 131, and the auxiliary contact portion 131 and the auxiliary member 14 are disposed between the first contact portion 111 and the second contact portion 121. In other words, the second contact portion 121 is closer to the auxiliary contact portion 131 than the first contact portion 111. With this arrangement, the distance between the second contact portion 121 and the auxiliary contact portion 131 is smaller than that between the first contact portion 111. When the consumables cartridge is loaded into the printing device, conductive material adhered to the cartridge moves to the surface of the chip 100 under the action of gravity and can be intercepted by the first and second contact pins, easily causing the conductive material to accumulate or remain between the auxiliary contact portion 131 and the second contact portion 121.

[0087] In one possible implementation, see Figure 2 As shown, the plurality of second contact portions 121 enclose an enclosed area 122. For example, three second contact portions 121 are arranged around the auxiliary contact portion 131, and the three second contact portions 121 enclose an enclosed area 122 (see Figure 2 the area enclosed by the dashed line).

[0088] Compared to the auxiliary contact portion 131, the auxiliary member 14 is further away from the enclosed area 122. The auxiliary contact portion 131 is disposed between the auxiliary member 14 and the second contact portion 121. In other words, the enclosed area 122 is closer to the auxiliary contact portion 131 than the auxiliary member 14. With this arrangement, when the consumables cartridge is loaded into the printing device, conductive material adhered to the cartridge moves to the surface of the chip 100 under the action of gravity and can be intercepted by the first and second contact pins. The conductive material is collected or retained in the enclosed area 122, making it easier for the conductive material to connect between the auxiliary contact portion 131 and the second contact portion 121, thereby facilitating the auxiliary contact portion 131's identification of short circuits between multiple second contact portions 121.

[0089] In one possible implementation, the substrate 10 has a center line A. The center line A extends along a height direction of the chip 100 .

[0090] The center line A divides the substrate 10 into a first area 101 and a second area 102 in the length direction of the chip 100 . That is, the first area 101 and the second area 102 are respectively provided on both sides of the center line A in the first direction.

[0091] The first contact portion 111 is located in the first area 101 , and the second contact portion 121 and the auxiliary contact portion 131 are located in the second area 102 .

[0092] A portion of the auxiliary member 14 is located in the first area 101 , and another portion of the auxiliary member 14 is located in the second area 102 .

[0093] It should be noted that in Figure 2 The portion between the dotted line B and the dotted line C is the auxiliary component 14 .

[0094] In a possible embodiment, the auxiliary component 14 may also be configured as a covering component.

[0095] In the length direction of the chip 100 , that is, in the first direction, the projection of the covering member covers the projection of the first terminal 11 and the projection of the auxiliary contact terminal 13 .

[0096] Example 2

[0097] See also Figure 4 As shown, the chip 100 in the second embodiment differs from the chip 100 in the first embodiment in that the area of ​​the chip 100 surface covered by the auxiliary component 14 is increased in the thickness direction of the chip 100 .

[0098] In a possible embodiment, the first terminal 11 and the auxiliary contact terminal 13 are covered by the auxiliary member 14 , and the plurality of second contact portions 121 are arranged around the auxiliary member 14 .

[0099] The structure of the remaining parts is the same as that of the first embodiment.

[0100] Example 3

[0101] See also Figure 5 As shown, the chip 100 in the third embodiment differs from the chip 100 in the first embodiment in that the auxiliary member 14 is configured as a line segment.
