Abstract
An electronic circuit is implemented on a substrate on an electrically conductive bottom plate fixed into an electromagnetic shield box. A coaxial socket is fixed to an outside wall of the shield box, the core of the socket being inserted in a hole in the wall in order to be connected to the electronic circuit. The socket has a grounding surface facing the wall. The grounding contact between the socket and the bottom plate is made by way of an electrically conductive ring coaxial with the core, insulated from the core and simultaneously in electrical contact with the grounding surface of the socket and the bottom plate when the socket is fixed to the wall of the box.
