  • Patent number: 5802709
    Abstract: A conductive polymer device includes an active element comprising a conductive polymeric layer laminated between a pair of electrodes to which terminal leads are attached. The active element is enclosed in an insulative package. Each of the electrodes may be formed integrally with its associated terminal lead in a single lead frame, with a layer of conductive polymeric material laminated between two such lead frames. Alternatively, a conductive polymeric layer may be laminated between two electrodes, with a terminal lead then being soldered to each electrode. The insulative package for the active element may be either an over-molded housing encasing the active element, or a pre-molded housing having a cavity into which the active element is installed, and which is then hermetically sealed with a suitable sealant material.

  • Patent number: 5466161
    Abstract: A device for electrically connecting the conductors on a first PC board to the conductors on a second PC board includes a housing having a mounting surface for mounting on the first board, an exposed surface opposite the mounting surface, and a pair of opposed side walls. A plurality of channels open through the exposed surface, each having an interior defined between the interior surfaces of the side walls. A compliant contact element, formed as an integral conductive element, is disposed in each channel.
