Abstract: Seal assemblies with a seal body having an inside flange and an outside flange that are biased outwardly away from one another by a spring energizer, such as a canted coil spring or a V-spring. The seal assemblies further include EMI shielding by incorporating at least one spring energizer that provides at least part of a conductive path between a housing and a pin. The conductive path can alternatively be provided by two different spring energizers and optionally with a conductive strip or trace or via a conductive contact ring element. The present seal assemblies are usable in applications having the needle for both sealing and EMI shielding.

Abstract: A dual spring contact assembly having an intermediate component between at least two canted coil springs with opposite canting angle directions for fitment between a first component and a second component. When there is relative displacement between the first and second components, the direction of movement of one of the components relative to one of the canted coil spring can always occur along the canting angle, reducing the friction between coils and component and increasing the life of the slip ring.

Abstract: Spring energized seal assemblies each with one or two sealing elements and a canted coil spring located in a spring cavity of the sealing element or of the two sealing elements to bias an inner flange and an outer flange of the respective spring cavity away from one another. The canted coil springs can have un-conventional coil shapes with one or more straight coil segments and/or with curved connecting ends. The coils can have dimples to provide multiple biasing points. The coils can have loops. The canted coil springs with un-conventional coil shapes can be used to improve spring loading on a sealing element.
