Apparatus and method for shielding a circuit from electromagnetic interference

A housing for shielding a circuit from electromagnetic interference, comprising:

• a shielding component including an interior that is adapted to receive and at least partially enclose the circuit, the shielding component having at least one aperture that provides access to said interior;
• and
• a plastic material molded over said shielding component, a portion of said plastic material being received within said at least one aperture of said shielding component during molding of said plastic material over said shielding component so that said plastic material forms an interlocking portion having a dimension that is greater than a dimension of said at least one aperture for securing said plastic material to said shielding component,
• said shielding component including an upset portion that extends outwardly from said shielding component, said interlocking portion of said plastic material being formed under said upset portion so that an end surface of said interlocking portion is flush with an interior surface of said shielding component.

A housing for shielding a circuit from electromagnetic interference, comprising:

• a shielding component including a top wall, front and back walls, and two side walls that collectively define an interior that is adapted to receive and at least partially enclose the circuit, a plurality of apertures extending through each of said top wall, said back wall, and said two side walls for providing access to said interior;
• and
• a plastic material molded over said shielding component, a portion of said plastic material being received within each aperture of said plurality of apertures during molding of said plastic material over said shielding component so that said plastic material forms a plurality of interlocking portions in said interior of said shielding component, each aperture of said plurality of apertures including an associated interlocking portion of the plurality of interlocking portions so that said plastic material is secured to said top wall, said back wall, and said two side walls of said shielding component,
• said top wall, back wall, and two side walls of said shielding component include a plurality of upset portions, extending from an associated wall of said top wall, back wall, and two side walls, each interlocking portion of said plurality of interlocking portions being formed under said upset portion so that an end surface of said interlocking portion is flush with an interior surface of said associated wall.
