Abstract

The invention provides a handwriting pen. The handwriting pen comprises a pen core, a capacitor, a substrate, a conductive bracket, a conductive spring and an elastic conductor, the capacitance value of the capacitor changes along with the pressure borne by the refill, and the capacitor is fixed to the substrate and communicated with the substrate. The conductive spring is clamped between the conductive bracket and the elastic conductor to keep an initial distance between the capacitor and the elastic conductor. The conductive elastic body transmits pressure borne by the refill to the conductive spring, the conductive spring reciprocates, the contact area of the elastic electric conductor and the capacitor is changed, and the capacitance value of the capacitor is changed. The handwriting pen is simple in structure, convenient to manufacture, assemble and maintain, sensitive, reliable and good in stability.

Description

technical field [0001] The invention relates to the technical field of computer peripheral equipment, in particular to a stylus. Background technique [0002] Digital electronic information equipment has the function of trajectory input, and the realization of this function usually adopts the mode of handwriting input. As a digital electronic information device, the pressure capacitive stylus has been widely used. It can not only input characters by handwriting, but also realize drawing and point control operations. [0003] The ceramic pressure capacitor of the stylus in the prior art requires separate leads for the two electrodes to lead out to the circuit board for soldering and conduction. The leads are thinner and the distance is longer, making it difficult to manufacture, difficult to assemble, easy to damage, and low in reliability. [0004] Therefore, there is an urgent need to provide a new pressure capacitive stylus to solve the above-mentioned technical problems ...
