Embodiments of a capacitive disk unit for a stylus for a capacitive touchscreen are disclosed. A conductive coupler has a flat proximal face and a socket for receiving a ball joint on its distal end. The distal portion of the socket may comprise a plurality of thin fingers that flex to capture the ball, forming notches between the fingers that are wide enough for the stylus shaft to pass into them, allowing the body of the stylus to be moved to a lower angle to the conductive coupler. Conductivity between the unit and the stylus is maintained continuously. If a larger diameter conductive surface is necessary, it may further comprise a disk and conductive layer, which may both be transparent. The conductive coupler may be molded of conductive polymer, and the disk may be overmolded using transparent polymer. Lack of metal parts reduces complexity, cost, and manufacturing defect risks. r.'4 r'.o r.'4 rNN C)c~ LL M-rj i i i (NJD C M - 0r% 0 r4 |
