AI Technical Summary

Technical Problem

The electrical connection components of existing printing equipment are large in size due to the dispersed terminal layout, which increases the difficulty of manufacturing, reduces design freedom and compatibility, and may cause communication instability issues.

Method used

Design an electrical connection component in which terminals on a chip are electrically contacted with conductive units through connecting components, and do not overlap with the projection of the pin assembly in a first direction. The terminals are centrally arranged, and the connecting components are used to make electrical contact with conductive units or pins, thereby reducing chip size and improving design freedom and adaptability.

Benefits of technology

This enables chip miniaturization, reduces manufacturing difficulty, improves the flexibility and adaptability of electrical connection components, ensures communication stability, extends service life, and saves costs.

Abstract

This utility model provides an electrical connection component and a consumable box. The electrical connection component is installed in the mounting unit of a printing device along with the consumable box. The printing device includes at least a stylus assembly and a conductive unit. The stylus assembly includes at least a first stylus and a second stylus. The electrical connection component includes: a chip with multiple terminals, including at least a first terminal and a second terminal; the first stylus for electrical contact with the first terminal; and a connecting component, the first part of which is for electrical contact with the second terminal. By constructing the electrical connection component so that its projection does not overlap with the projection of the second stylus of the stylus assembly in a first direction, and by allowing the second terminal of the chip to make electrical contact with the conductive unit or the first stylus through the connecting component, chip miniaturization is facilitated. Simultaneously, the freedom and flexibility of the terminal arrangement design on the chip are improved, enhancing the chip's adaptability.
