Description

Electric wiring component, consumable chip and ink box Technical Field The embodiment of the application relates to the technical field of printing and imaging, in particular to a consumable chip and imaging equipment using the consumable chip. As the form of the image forming apparatus, in addition to a general printing apparatus, a copying machine, a facsimile machine having a communication system, a word processor having a printing unit, or the like, or a multi-function recording apparatus or the like in which these apparatuses are combined may be taken. Background With the continuous development of inkjet recording technology, image forming apparatuses are widely used in the fields of home, office, and industry. The main advantages of the image forming apparatus include low cost, low operation noise, excellent printing quality, and adaptability to various printing media such as plain paper, photo paper, slide film, and the like. Among the core components of imaging devices, consumable chips play a critical role, being the key component responsible for ejecting ink as tiny ink droplets onto the print medium, whose performance directly affects the definition, color rendition, and overall quality of the print. Generally, a consumable chip includes a printhead chip and an electrical wiring member. The printhead chip receives a signal transmitted from the image forming apparatus through the electrical wiring member, and performs ink ejection under the control of the signal transmitted from the image forming apparatus. The print head chip belongs to the field of integrated circuit design, and has high design cost, long period, etc. and has high integrated circuit producing cost, so that lower cost repairing mode, etc. is required. Wherein the electrical wiring member includes a plurality of contacts thereon. When the consumable chip is mounted on the imaging device, the plurality of contacts on the electrical wiring member are respectively and electrically connected with corresponding contact pins on the imaging device through the contacts so as to receive signals sent by the imaging device. The electrical wiring member includes a contact area provided with a plurality of contact points, the contact area including a corner area and a non-corner area, the corner area being arranged at a corner of the contact area, the non-corner area being other areas than the corner area of the contact area, the plurality of contact points including a corner contact point provided at the corner area and a non-corner contact point provided at the non-corner area. When offset occurs during the mounting of the consumable cartridge, the corner contacts within the corner regions are offset more than the non-corner contacts within the corner regions are offset less than they are. Therefore, the use of the corner area contacts to detect whether the consumable cartridge is properly mounted is a good mounting detection approach. However, some imaging apparatuses exist, and the replaceable consumable cartridge (or ink cartridge) used is a consumable cartridge including a printhead chip, and when the consumable (such as ink) in the consumable cartridge is exhausted, the entire consumable cartridge needs to be replaced (of course, there is a way to continue filling ink into the consumable cartridge, and the consumable cartridge can be repeatedly used, where the replacement refers to that the entire consumable cartridge can be freely detached and replaced). Imaging device styli that typically use consumable cartridges with printhead chips are more complex because of the control of multiple ejection elements in the printhead chip to eject ink (e.g., in a piezoelectric or thermal manner), and thus the control logic is more complex, requiring more signals to control the reading and writing of ink and/or data with accuracy. Therefore, such a consumable cartridge is typically provided with a large number of contacts, such as 8, 9, 10, or even more, such as 20, 30, 40, etc., on the electrical wiring member. This results in a larger footprint for the contact points that make contact with the contact pins, a more complex wiring, and a higher cost, and because of the greater number of contact points, the flexibility of wiring is limited and routing is difficult in the case where these contact points are in contact with the pads of the printhead die. In addition, because the area occupied by the contact is large, when a consumer installs or changes a consumable box, the consumer experience is affected because the consumer takes different postures, and because the consumer takes more corner contacts to participate in installation and detection in some existing modes, the consumable box is not recognized by some customers frequently, and the consumer experience is influenced due to the fact that the consumable box needs to be installed again or repeatedly. In addition, more corner contacts participate in installation and detection and have some probl
