[0047] The chip assembly and ink cartridge assembly provided by the embodiments of the present invention are described in detail below in conjunction with specific embodiments.

[0048] like Figures 1 to 5 As shown, an embodiment of the present invention provides a chip component 100, including a substrate 10, which is divided into a plurality of contact areas; each of the plurality of contact areas includes a storage element 101 and a plurality of direct contact terminals, the plurality of direct contact terminals are electrically connected to the storage element 101, and the plurality of direct contact terminals in each contact area are used to electrically connect to the contact pins corresponding to each ink cartridge body of the ink cartridge group 200 in the image forming device.

[0049] The plurality of contact regions include a first contact region 11 . The plurality of direct contact terminals of the first contact region 11 include a direct contact power terminal 102 . The direct contact power terminal 102 is used to transmit a power signal to the storage elements 101 of the remaining contact regions except the first contact region 11 .

[0050] The plurality of contact regions include a second contact region 12 . The plurality of direct contact terminals of the second contact region 12 include a direct contact ground terminal 103 . The direct contact ground terminal 103 is used to transmit a ground signal to the storage elements 101 of the remaining contact regions except the second contact region 12 .

[0051] Among them, Figure 4 As shown, the length direction of the chip assembly 100 is the X-axis direction, the width direction of the chip assembly 100 is the Y-axis direction, and the thickness direction of the chip assembly 100 is the Z-axis direction. The X-axis, Y-axis and Z-axis are perpendicular to each other.

[0052] The plurality of contact regions are sequentially arranged along the length direction of the chip assembly 100 , and the order of the plurality of contact regions in the length direction of the chip assembly 100 is not specifically set.

[0053] like Figure 2 As shown, each ink cartridge body corresponds to a contact area, which can be understood as each inner liner 210 corresponding to a contact area. The contact area can be understood as a part of the substrate 10.

[0054] The number of contact areas may be 2. In other embodiments, the number of contact areas may be greater than 2. Specifically, the number of contact areas is set to 3, 4, 5 or more. In the embodiments of the present application, there is no limitation on the number of contact areas.

[0055] like Figure 4 and Figure 5 As shown, the storage element 101 and the plurality of direct contact terminals of each contact region may be respectively located on both sides of the substrate 10 in the thickness direction of the chip assembly 100 .

[0056] The number of direct contact terminals of the first contact area 11 is the same as the number of direct contact terminals of the second contact area 12 .

[0057] The first contact region 11 may be any one of the remaining contact regions except the second contact region 12 , and the second contact region 12 may be any one of the remaining contact regions except the first contact region 11 .

[0058] In some examples, the remaining contact areas of the substrate 10 except the first contact area 11 may not have the direct contact power terminal 102, that is, the remaining contact areas of the substrate 10 except the first contact area 11 do not have the direct contact power terminal 102 that contacts the contact pin for transmitting the power signal in the image forming device, the direct contact power terminal 102 of the first contact area 11 can contact the contact pin for transmitting the power signal in the image forming device, and the direct contact power terminal 102 of the first contact area 11 can transmit the power signal to the storage element 101 of the remaining contact areas except the first contact area 11, thereby ensuring that the remaining contact areas of the substrate 10 except the first contact area 11 can still obtain power without the direct contact power terminal 102. Source signal; the remaining contact areas of the substrate 10 except the second contact area 12 may not have the direct contact grounding terminal 103, that is, the remaining contact areas of the substrate 10 except the second contact area 12 do not have the direct contact grounding terminal 103 contacted by the contact pin for transmitting the grounding signal in the image forming device, the direct contact grounding terminal 103 of the second contact area 12 may contact the contact pin for transmitting the grounding signal in the image forming device, and the direct contact grounding terminal 103 of the second contact area 12 may transmit the grounding signal to the storage element 101 of the remaining contact areas except the second contact area 12, thereby ensuring that the remaining contact areas of the substrate 10 except the second contact area 12 can still obtain the grounding signal in the absence of the direct contact grounding terminal 103.

[0059] The embodiment of the present invention provides a chip component 100, wherein the plurality of contact areas include a first contact area 11 and a second contact area 12, wherein a direct-contact power terminal 102 of the first contact area 11 contacts a contact pin for transmitting a power signal in an image forming device and receives the power signal transmitted by the contact pin, and the power signal is then transmitted to a storage element 101 provided in the first contact area 11 via the direct-contact power terminal 102, and the storage element 101 transmits the power signal to the storage elements 101 in the remaining contact areas except the first contact area 11, and a direct-contact grounding terminal 103 of the second contact area 12 contacts a contact pin for transmitting a grounding signal in the image forming device and receives the grounding signal transmitted by the contact pin, and the grounding signal is then transmitted to the storage element 101 in the second contact area 12 via the direct-contact grounding terminal 103, and the storage element 101 transmits the power signal to the storage elements 101 in the remaining contact areas except the second contact area 12. The storage element 101 of the remaining contact areas transmits the ground signal, so that the remaining contact areas except the first contact area 11 do not need to be provided with the direct contact power terminal 102, and the remaining contact areas except the second contact area 12 do not need to be provided with the direct contact grounding terminal 103, so that the contact area on the ink cartridge body corresponding to the accidentally bent contact pin does not need to be provided with the direct contact power terminal 102 or the direct contact grounding terminal 103, and the contact area on the ink cartridge body corresponding to the direct contact power terminal 102 with terminal wear or oxidation failure problem does not need to be provided with the direct contact power terminal, and the contact area on the ink cartridge body corresponding to the direct contact grounding terminal 103 with terminal wear or oxidation failure problem does not need to be provided with the direct contact grounding terminal, thereby achieving stable communication between the chip component 100 of the ink cartridge group and the contact pin of the image forming device, thereby improving the stability of the use of the chip component of the ink cartridge group.

[0060] By making it unnecessary to set the direct contact power terminal 102 in the remaining contact areas except the first contact area 11, and unnecessary to set the direct contact grounding terminal 103 in the remaining contact areas except the second contact area 12, the direct contact power terminal 102 and the direct contact grounding terminal 103 of the chip component 100 are respectively arranged in different contact areas, so that the direct contact power terminal 102 and the direct contact grounding terminal 103 are fully separated, which can effectively avoid the situation in which ink droplets or conductive impurities adhere to the direct contact power terminal 102 and the direct contact grounding terminal 103 during use, or the direct contact power terminal 102 and the direct contact grounding terminal 103 are short-circuited due to other reasons, thereby causing the risk of burning the chip component 100, thereby improving the safety of the chip component of the ink cartridge group.

[0061] In a possible implementation manner, the number of direct contact terminals in two adjacent contact areas is the same; or the number of direct contact terminals in one of the two adjacent contact areas is less than the number of direct contact terminals in the other contact area.

[0062] In some examples, such as Figure 4 and Figure 5As shown, when the substrate 10 is divided into two contact areas, the two contact areas are divided into a first contact area 11 and a second contact area 12, the number of direct contact terminals in the first contact area 11 is the same as the number of direct contact terminals in the second contact area 12, the first contact area 11 does not have a direct contact ground terminal 103, and the second contact area 12 does not have a direct contact power terminal 102.

[0063] In other examples, such as Fig.10 and Fig.11 As shown, when the substrate 10 is divided into four contact areas, the four contact areas are divided into a first contact area 11, a second contact area 12, a third contact area 13 and a fourth contact area 14. In the length direction of the chip component 100, the third contact area 13 and the fourth contact area 14 are located between the first contact area 11 and the second contact area 12, the third contact area 13 and the fourth contact area 14 are adjacent to each other, the number of direct contact terminals in each of the third contact area 13 and the fourth contact area 14 is one less than the number of direct contact terminals in the first contact area 11, the number of direct contact terminals in the first contact area 11 is the same as the number of direct contact terminals in the second contact area 12, and the number of direct contact terminals in each of the third contact area 13 and the fourth contact area 14 is one less than the number of direct contact terminals in the second contact area 12. The first contact area 11 is constructed to be adjacent to any one of the third contact area 13 and the fourth contact area 14. Specifically, when the first contact area 11 is adjacent to the third contact area 13, the second contact area 12 is adjacent to the fourth contact area 14; when the first contact area 11 is adjacent to the fourth contact area 14, the second contact area 12 is adjacent to the third contact area 13.

[0064] In a possible implementation, each contact area includes an auxiliary contact area, and the auxiliary contact area is electrically connected to the storage element 101 of the corresponding contact area; the auxiliary contact area includes an auxiliary contact power supply unit 107 and / or an auxiliary contact grounding unit 108, the direct contact power supply terminal 102 of the first contact area 11 is electrically connected to the auxiliary contact power supply unit 107 of the remaining contact areas except the first contact area 11, and the direct contact grounding terminal 103 of the second contact area 12 is electrically connected to the auxiliary contact grounding unit 108 of the remaining contact areas except the second contact area 12. It should be noted that, if Figure 8 As shown, when the first contact area 11 displays the auxiliary contact grounding portion 108 , the second contact area 12 displays the auxiliary contact power supply portion 107 .

[0065] Among them, multiple direct contact terminals of each contact area are exposed on the surface of the substrate 10, and the auxiliary contact area of ​​each contact area is arranged inside the substrate 10. It can be understood that multiple direct contact terminals and the auxiliary contact area are provided with multiple isolation layers, multiple direct contact terminals are exposed outside the isolation layer, the auxiliary contact area is covered by the isolation layer, and the multiple isolation layers are formed by silk screen printing.

[0066] like Figure 8As shown, the auxiliary contact area of ​​the second contact area 12 may include an auxiliary contact power supply portion 107; Figure 8 As shown, the auxiliary contact area of ​​the first contact area 11 may include an auxiliary grounding portion 108; Fig.14 As shown, the auxiliary contact areas of the third contact area 13 and the fourth contact area 14 may include an auxiliary contact power supply portion 107 and an auxiliary contact grounding portion 108 .

[0067] The auxiliary contact power supply unit 107 and the auxiliary contact grounding unit 108 are located inside the substrate 10. In order to avoid a short circuit between the power signal and the grounding signal, the auxiliary contact power supply unit 107 and the auxiliary contact grounding unit 108 can be insulated and isolated.

[0068] The direct contact power terminal 102 of the first contact area 11 is electrically connected to the auxiliary contact power supply part 107 of the remaining contact areas except the first contact area 11 through the storage element 101 of the first contact area 11. Specifically, the direct contact power terminal 102 of the first contact area 11 contacts the contact pin for transmitting the power signal in the image forming device and receives the power signal transmitted by it, and the power signal is then transmitted to the storage element 101 provided in the first contact area 11 via the direct contact power terminal 102. The storage element 101 can be electrically connected to the auxiliary contact power supply part 107 of the remaining contact areas except the first contact area 11, so that the storage element 101 except the first contact area 11 can obtain the power signal, thereby ensuring that the remaining contact areas of the substrate 10 except the first contact area 11 can still obtain the power signal in the absence of the direct contact power terminal 102.

[0069] The direct contact grounding terminal 103 of the second contact area 12 is electrically connected to the auxiliary contact grounding portion 108 of the remaining contact areas except the second contact area 12 through the storage element 101 of the second contact area 12. The direct contact grounding terminal 103 of the second contact area 12 contacts the contact pin for transmitting the grounding signal in the image forming device and receives the grounding signal transmitted by it. The grounding signal is then transmitted to the storage element 101 provided in the second contact area 12 via the direct contact grounding terminal 103. The storage element 101 can be electrically connected to the auxiliary contact grounding portion 108 of the remaining contact areas except the second contact area 12, so that the storage element 101 of the remaining contact areas except the second contact area 12 can obtain the grounding signal, thereby ensuring that the remaining contact areas of the substrate 10 except the second contact area 12 can still obtain the grounding signal without the direct contact grounding terminal 103.

[0070] In a possible implementation, in the thickness direction of the chip assembly 100, the projection of at least one direct contact terminal of the contact area at least partially overlaps with the projection of the auxiliary contact area of ​​the contact area. It can be understood that in the thickness direction of the chip assembly 100, the projection of at least one direct contact terminal of any contact area of ​​the substrate 10 at least partially overlaps with the projection of the auxiliary contact area of ​​the contact area. With such an arrangement, the area of ​​the plane where the direct contact terminal of the contact area of ​​the substrate 10 is located can be reduced, thereby reducing the area of ​​the substrate 10 and reducing the production cost of the substrate 10.

[0071] In a possible implementation manner, the number of auxiliary contact power supply portions 107 of the remaining contact areas except the first contact area 11 is the same, and the number of auxiliary contact grounding portions 108 of the remaining contact areas except the second contact area 12 is the same.
