Capacitive Touch Cover With Conductive Key Top Intermediary

The patent introduces conductive portions (first and second conductive portions) as intermediaries between the key top and the touch screen. When the key top is pressed, these conductive portions make contact with the touch screen to simulate touch input, enabling operation through the cover without bare hand contact.

The conductive system is divided into separate components: the first conductive portion contacts the touch screen directly, while the second conductive portion connects to the first conductive portion through the operated key top. This segmentation allows the cover to maintain structural integrity while enabling touch operation through distributed conductive elements.

The conductive portions serve as intermediaries that transfer the mechanical pressing action of the key top to the touch screen, bypassing the need for direct hand contact. This mediator system ensures accurate touch input registration regardless of whether the user is bare-handed or wearing non-conductive gloves.

The patent replaces the direct mechanical touch system (hand touching screen) with an indirect mechanical-electrical system where key top pressing activates conductive portions that then contact the touch screen. This substitution enables operation under diverse conditions including glove wear while maintaining input accuracy.

Rather than making the entire cover conductive or complex, the patent applies conductive portions only at specific locations where key tops are positioned. This localized approach enables touch operation functionality while keeping the rest of the cover structure simple and maintaining overall design elegance.

The conductive portions are integrated into the key top structure itself, merging the mechanical key operation function with the electrical touch input function. This integration reduces the need for separate complex components while enabling dual functionality through the same structural elements.
