Description

Technical Field

[0001] This utility model relates to the field of electronic capacitive pen technology, specifically an active capacitive pen with a minimalist structure. Background Technology

[0002] A capacitive stylus is a pen made of conductive materials with conductive properties, used to interact with capacitive screens and facilitate human-computer interaction. It mimics the human body (usually a finger) through its conductive material. With the development of apps, capacitive pens are no longer simply replacements for finger operation; more and more professionals are using active capacitive pens on mobile devices. The pen tip is an integral part of the capacitive pen.

[0003] As the industry develops, the market demand for pens is increasing, while product prices are decreasing. Traditional active capacitive pens have complex structures, requiring time and manpower for assembly, resulting in high costs that clearly cannot meet market demands. Furthermore, structural components always have inherent tolerances, leading to either poor writing functionality or misaligned charging ports that prevent charging. Utility Model Content
