Abstract: The invention relates to an electrical connector (15) comprising a cable connection part (15a) and a circuit-board connection part (15b), wherein the metallic casings (16, 17) of the connection parts are electromagnetically screening and earth potential connected and include means (such as 20) for providing the casings (16, 17) of respective connecting parts (15a, 15b) with a common earth potential (5') when the parts are in a mutually coacting state. The circuit board (4) includes edge-oriented, and resilient electrical contact means (30) connected to earth potential and coacting with the metallic casing of the circuit-board connecting part. A unit provided with electrical contact devices and positioned within the electrical contact means (30) is connected by its associated connecting device or devices with a circuit-board contact surface or surfaces through the medium of connecting wires or connecting pins.

Abstract: The invention relates to a coaxial cable plug-in assembly for coaxial cables and including an electrical connection assembly. The electrical connection assembly can be connected to ground potential. The plug-in assembly includes two complementary parts. At least one of the plug-in assembly parts embraces an electrically insulating base member which is intended to accommodate a connecting device and which includes at least one through-penetrating hole adapted for coaction with a first subpart of a sleeve-like connecting device, and with a second subpart adapted for coaction with a coaxial cable whose screening conductor is intended to embrace the second subpart of the connecting device. The electrical connection assembly includes a spring-like collar which extends completely or partially around the second subpart of the connecting device for electrical and mechanical coaction between the subpart and the collar, and further includes a supportive part which coacts with the collar.
