An electromagnetic shielding structure has conductive parts for blocking
propagation of electromagnetic interference, whereof at least one has an
appendage or an edge configuration that is shaped so as to bite into the
edge of the other of the conductive parts, such as along a narrowing
groove. The appendage or edge can have a structure resembling an
insulation displacement connector, but is arranged to engage the edge of
a sheet-like or planar shielding element, as opposed to biting into an
insulated wire. The connection achieves both electrical and mechanical
connection between the parts, preferably thereby completing at least part
of a shielding enclosure.
