US Patent 7390978 Overmolded electronic assembly and overmoldable interface component

An overmolded electronic assembly (900, 1000, 1200) is fabricated from one or more overmoldable interface components (300, 400, 500, 1220, 1750) that may be electrical contacts or electronic components that have physical interfaces, such as speakers or sensors. The overmoldable interface components have a sacrificial end that is cut off from the remainder of the overmoldable interface components after being overmolded in an electronic assembly, providing a sealed cavity into the overmolded electronic assembly.
