Plate Connector Geometry for Locking Gapped Sheet Components

The patent changes the geometric parameter of the tab by providing an insertion surface that is inclined relative to the longitudinal axis of the center section. This inclined surface creates a wedge effect that converts rotational motion into compressive force, pressing the sheet-shaped components together during rotation. This allows the connecting element to be rotated into locking position even when the components do not fully touch, while simultaneously establishing a secure connection through the compressive force generated by the inclined insertion surface.

The patent applies local quality by making the height H of the insertion region variable along its length. Specifically, the insertion surface is inclined such that the height decreases from one end to the other. This creates different local conditions: one end has greater height to engage first and guide the rotation, while the other end has lesser height to be pressed down onto the component. This gradient in height enables the components to be displaced toward each other during rotation while maintaining manufacturability through a simple inclined surface geometry.
