Abstract
Abstract A device for shielding assemblies having multi-pole plugs. Shielding caps of multi-pole plugs having spring elements that, in the plugged-in condition of the plugs, press against contact elements oriented perpendicularly on a wiring board and connected to a grounded potential layer thereof. Metallic shielding surfaces that at least partially surround the assemblies are voltaically connected to the shielding caps with metallic connecting elements, preferably spring elements.
