Abstract: In an exemplary embodiment, primary and secondary coupling elements are disposed in a recess of a first housing and in a second housing which can be inserted into the recess of the first housing as a plug part. The coupling elements exhibit connection surfaces which are fitted to one another and via which a coupling location is produced upon production of the plug-type connection. The goal of the disclosure is to construct a galvanically separating coupling location of the type initially cited which, given particularly high electric strength and given optimum insulation, allows energy and/or signal transmission with an optimally high efficiency. This object is inventively achieved in that the coupling elements are suspended in a floating and resilient manner in the respective housings relative to at least one connection surface, preferably, however, relative to respective connection surfaces which enclose the respective coupling elements.

Abstract: In an exemplary embodiment, a device housing with a signal processing part, includes at least one recess into which at least one insert with a cladding of insulation material of high electric strength can be inserted as a signal transmission part, whereby both the recess wall and the insert are carriers of mutually cooperating primary and secondary coupling elements of a galvanically separating coupling location for energy and signal transmission, the coupling elements, however, only combining to form the coupling location when the insert is inserted into the recess. The object of the disclosure is to create such a device which allows of combinations consisting of the recess and the insert which are dimensioned to provide as large a volume or as large a surface area as desired without having a leakage current which may be possibly flowing assuming an inadmissibly high value as a result.

Abstract: A plug contact assembly, comprising a female plug member and a corresponding male plug piece, is provided with an interlocking means utilizing a locking tongue member which is protected from deformation and mechanical stress within the confines of an annular surrounding socket wall. The tongue is a free-extending, resilient member having at least one detent hump formed thereon and arranged to engage into an associated detent recess formed along a generally flat base wall surface of the other plug section to establish a locking interconnection of the plug contact members. The tongue is spaced beneath an adjacent edge of a plug head portion to define therebetween a groove into which the base wall of the other associated plug section slides during interengagement of the plug members.

Abstract: The object of the disclosure is to construct an insert which, given the simplest structure, is optimally insulated and and voltage-stable. This goal is achieved in that the insert is composed of a jacket housing of highly insulating synthetic, for example, amino-butadienestyrol (ABS) or the like, and of a layer packet comprised of at least two shielding plates of, for example, aluminum or sheet steel, with a printed circuit board structure seated between them as a carrier for those components which are required for the energy and/or signal transmission, said layer packet being designed so as to be insertable into the highly insulating jacket housing.
