A cam-based, force-controlled system for seal activation includes a plurality of sealing segment assemblies. Each sealing segment assemblies includes an inner segment and an outer segment assembly configured to mate with the inner segment. The inner segment includes an upper segment portion, a lower segment portion, and an inner segment seal disposed between the upper segment portion and the lower segment portion. The outer segment assembly includes an upper segment element, and outer perimeter element, an outer segment seal disposed between the upper segment element and the outer perimeter seal, a rod coupled to the upper segment element, a first cam coupled to the upper segment element, a second cam coupled to the upper segment element, and a handle coupled to the rod, the first cam, and the second cam.

Apparatus and associated methods relate to a stretchable cover assembly permeable to electromagnetic signals formed within an enclosed device envelope to increase the resilience of the actuator body envelope against high-pressure fluid. In an illustrative example, a cover assembly is configured to encapsulate an electronic device. For example, the cover assembly may include a unitary envelope formed from a translucent, radio permissive, and ultraviolet light reflective material. An internal cavity defined by the unitary envelope may repeatedly receive substantially an entire exposed surface of the electronic device. The cover assembly may include an elastic opening that, in a relaxed state, the elastic opening is configured to be sealingly pressed against the enclosed electronic device forming a seal around the entire elastic opening to form a dust-tight and watertight cover. Various embodiments may advantageously protect the enclosed electronic device while selectively permitting electromagnetic signals to pass through.

The connection device for connecting two electric units, including a case in which are arranged: an electric wire to be linked to the first unit and including a conductive core encircled by an insulating sheath and a conductive tab to be linked to the second unit and secured with the stripped end of the conductive core, all of which being immersed in a sealing material filling the case and bonded to the insulating sheath, the device including an intermediate envelope partially coating the insulating sheath, so that it is in contact with the sealing material only over a reduced portion, where the intermediate envelope is in sliding contact with the sealing material and/or the insulating sheath.

To create a housing cover for fixing to a housing, wherein the housing cover is provided with a plurality of fastening means through openings and with a sealing bead that comprises an elastomeric material, and wherein the sealing bead is arranged on a seal support face of the housing cover, in which housing cover the course of the sealing bead can be more freely designed and, in particular, laid closer to the fastening means through-openings of the housing cover and which, in particular, is producible from a sheet-shaped starting material, it is proposed that the housing cover comprises at least one deformation limiting element, which projects over the seal support face in the same direction as the sealing bead and limits a deformation of the sealing bead in the assembled state of the housing cover, wherein the deformation limiting element comprises at least one fastening means through-opening portion that extends along a circumferential direction of one of the fastening means through-openings over a circumferential angle α around the respective fastening means through-opening, and wherein the fastening means through-opening portion of the deformation limiting element comprises a plurality of partial element that are spaced at a distance from one another along the circumferential direction of the fastening means through-opening.

This application describes covers for electronic devices, electronic devices, and methods for making the covers. In one example, a cover comprises a substrate comprising a first metal; a second metal injection molded 10 on the surface of the substrate; a paint layer or an electrophoretic deposition layer on the second metal surface; a chamfered edge on the substrate, wherein the chamfered edge cuts through the paint layer or the electrophoretic deposition layer, the second metal, and partially through the first metal; and a hydrophobic coating.

A household appliance includes a housing having an accommodating cavity. The accommodating cavity has an installation opening. An electrical appliance is adapted to enter the accommodating cavity through the installation opening. A cover is configured to seal the accommodating cavity. The housing has a disassembling hole adapted to receive an insertion of a tool configured to disassemble the cover from the housing. The disassembling hole is in communication with the accommodating cavity and an entrance of the disassembling hole is located outside the installation opening.
