Abstract:
A sealed electronic module includes a housing (10) having an open end for receiving a circuit board (26), and a slotted side wall (14) for receiving a connector header (34) mounted on the circuit board (26). The connector header (34) fits snugly in the side wall slot (32) and includes an integral trough (44) that engages the interior face of the side wall (14) to form a U-shaped channel that surrounds the sides and bottom of the slot (32). The housing (10) is positioned with its open end upward, and potting material (52) is dispensed onto the exposed surface of the circuit board (26) in a single step to seal the circuit board (26) to the housing (10). A portion of the potting material (52) flows into and fills the U-shaped channel to seal the connector header (34) to the housing (10).
Abstract:
An electronic component assembly includes an electrical component (12) assembled to a base (14) and mounted to a support (16). The component electrical leads (20,21) protrude through holes, along a channel, and make contact with connectors (38) on the base. The base (14) is formed of a polymeric material and contains protrusions (44) for mechanically supporting the electrical component. When the base is mounted to the support, the connectors complete the electrical connection between the electrical component (12) and the support (16).

Abstract:
A stand-off mounting apparatus (10/50/80) includes an insulative carrier (12/52/82) for off-board mounting of leaded or surface-mount components (18, 20/58-62/92-96), particularly large temperature-sensitive discrete components such as capacitors. The carrier (12/52/82) has a component-mounting surface that is elevated relative to the circuit board (14), and is positioned with respect to the circuit board (14) such that the circuit board area under the mounting surface of the carrier (12/52/82) is available for the placement of smaller non-temperature-sensitive components. The off-board components (18, 20/58-62/92-96) are mounted on the component-mounting surface of the carrier (12/52/82), and the carrier (82) may include support features (102) for providing additional mechanical support for the components (92-96). Electrical leads (16/56/88) for electrically coupling the elevated components (18, 20/58-62/92-96) to the circuit board (14) may be insert-molded in the carrier (12/52), or may be inserted into plated through-holes (110) in the carrier (82).
