  • Apparatus and method for shielding a circuit from electromagnetic interference
    Patent number: 6709291
    Abstract: A housing (10) for shielding a circuit (12) from electromagnetic interference comprises a shielding component (20) having at least one aperture (40). A plastic material (50) is molded over the shielding component (20). A portion (54) of the plastic material (50) is received within the aperture (40) for securing the plastic material to the shielding component (20). A method of making a housing (10) for shielding a circuit (12) from electromagnetic interference includes the steps of providing a shielding component (20) having an aperture (40); molding a plastic material (50) over the shielding component; and securing the plastic material to the shielding component by receiving a first portion (54) of the plastic material into the aperture in the shielding component.

  • Apparatus and method for shielding a circuit from electromagnetic interference
    Patent number: 6431884
    Abstract: A housing (10) for shielding a circuit (12) from electromagnetic interference comprises at least one electrically conductive connector pin (50) having a central portion, a first end portion (62) and a second end portion (66). The housing (10) also comprises an insulator (70). The central portion of the connector pin (50) is disposed within the insulator (70). The first end portion (62) and the second end portion (66) of the connector pin (50) extend outward from the insulator (70). The housing (10) includes a housing body (20) made from an electrically conductive moldable plastic material (22). The housing body (20) is molded over at least a portion of the insulator (70) to secure the insulator and thereby the connector pin (50) in the housing (10).
