Abstract: A clamping device (10) is configured to apply opposite clamping forces in both a first (x-axis) and second (z-axis) traverse direction when being compressed in a longitudinal direction (y-axis) to fix elements to another. The device includes clamping means able to transform compressive movements and/or forces in said longitudinal direction into expanding movements and/or forces in both said traverse directions until the expansion is stopped by abutment in said traverse directions upon adjacent elements for application of clamping forces. Additionally, the compressive force used to generate the clamping forces in both said traverse directions allows for attaching the device to a support for fixing an element in all three directions by one single manual operating action.

Abstract: An aluminum enclosure of an electronic device is used in a corrosion environment. A long-term low impedance ground connection is needed because of security and EMC reasons. While common surface protection for aluminum in corrosion environments as for example polyurethane paint is not conductive, a stainless steel connector is provided which comprises a head portion and a bolt portion. The bolt portion is inserted into a bore of the enclosure or frame. An annular rib provided on the back side of the head portion defines a cutting edge which cuts into the surface of the aluminum enclosure and provides a gas-tight electrical contact. The front surface of the stainless steel head of the electrical connector element provides a metallic surface for connecting ground wires or other conductors.
