Abstract
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.
Claims10
An electromagnetic shielding structure, comprising:
- at least one elongated first element defining an electrically conductive barrier surface against propagation of electromagnetic energy through said first element;
- at least one second element, generally oriented along the conductive barrier surface defined by the first element, for continuing said barrier surface against propagation of electromagnetic energy;
- wherein at least one of the first and second elements has at least a portion of a limited length, oriented to cross a plane of the barrier surface defined by the other of said first and second elements, said first and second elements defining crossing parts, wherein said portion has a receiving slot into which the other of said first and second elements is insertable, said receiving slot having an inside width that is nominally smaller than an outside width of said other of said first and second elements for insertion into the receiving slot, wherein at least one of said receiving slot and said other of the first and second elements is deformed by said insertion, and wherein the first and second elements are electrically and mechanically connected by said insertion.
A method for electromagnetically shielding a load, comprising the steps of:
- defining a shielding enclosure around the load for blocking at least one of ingress and egress of electromagnetic energy;
- placing a first element comprising a conductive material to provide a conductive barrier surface encompassing part of the shielding enclosure;
- continuing the conductive barrier surface by placing at least one second element comprising a conductive material, to encompass a further part of the shielding enclosure, wherein the second element is generally oriented along the conductive barrier surface defined by the first element;
- crossing the first and second elements over at least a portion of a limited length at which one of the first and second elements has a receiving slot, wherein the receiving slot has an inside width that is nominally smaller than an outside width of said other of said first and second elements for insertion into the receiving slot;
- inserting an edge of the other of said first and second elements into the receiving slot, thereby deforming at least one of said receiving slot and said edge inserted therein, wherein insertion of the edge in the receiving slot mechanically attaches and electrically couples the first and second elements.
