Abstract

Abstract Shielding apparatus for an electrical assembly. A shroud that covers a front cover of the assembly is located at the front side of the electrical assembly that is insertable into a magazine. The shroud is snapped onto the front cover with retaining tabs and has laterally resilient contact tabs that are contacted by contact tabs of neighboring shrouds. As a result, the shrouds are directly connected to one another, so that only one electrical junction between the shielding parts is established per assembly. In particular, the shielding effect is so effective that the shrouds can be utilized in radio-frequency electrical systems.
