Abstract
A system may utilize a structural fastener, such as a screw, as a dual-function component in compact electronic devices (e.g., smartphones, wearables, tablets). The fastener can be constructed from a conductive material and feature a selectively applied insulating coating on certain surfaces, for example, the threaded shank that engages with a conductive housing. The head of the fastener and a portion of its tip may remain uncoated to serve as external and internal electrical contact points, respectively. This configuration can allow the fastener to provide both mechanical fastening and an electrical conduit. This approach may facilitate a space-efficient, hidden wired interface for data or power transmission, potentially reducing the need for a dedicated external port.
