Abstract: A housing assembly for an electrical connector that can be plugged together with a mating connector along a plugging direction includes a connector housing, a mating aid arranged on the connector housing and movable between an initial position and a final position, and a securing element arranged on the mating aid and movable between a secured position and a release position. The mating aid has a drive section engaging the mating connector to move the mating connector into a state in which the mating connector is plugged together with the electrical connector. The securing element in the secured position engages the connector housing and in the release position is disengaged from the connector housing. The securing element in the secured position is accessible for the mating connector from outside of the housing assembly and is movable to the release position by the mating connector.

Abstract: Cured silicone rubbers for acoustic damping, and formulations and methods used to make the same, are provided.

Abstract: Aspects are disclosed of an acoustically active coating. The coating is a porous coating having a thickness and including between 2% and 30% by mass of a binder and between 70% and 98% by mass of a zeolite. The coating comprises a plurality of convex shapes connected by concave connectors and has a distribution of pore sizes. Other embodiments are disclosed and claimed.

Abstract: Aspects are disclosed of a filler for occupying a volume. The filler includes an expandable filler positioned in the volume so that it occupies a percentage of the volume. The expandable filler can permanently expand from a first dimension to a second dimension upon the application of an expansion trigger. The filler also includes an acoustic filler made up of a plurality of acoustically active beads positioned with the expandable filler in the volume so that the acoustic filler can adsorb gas flowing into the volume. Other embodiments are disclosed and claimed.
