Shield cover and shielding method using the same

Claim 1

An electromagnetic shield for at least one electronic component mounted on a printed circuit board comprising: an enclosure having an open end, side walls, and a top wall opposite the open end, edges of the side walls opposite the top wall defining the open end, the enclosure at least partially formed from an electrically conductive, electromagnetic wave absorbing material; flexible locking arms integrally formed with the enclosure extending below and perpendicular to the side wall edges, said flexible locking arms having a locking nib adapted to first contact an aperture in said printed circuit board causing said flexible locking arm to slightly bend and then to snap under said printed circuit board when said nib completely passes through said aperture allowing the flexible locking arm to return to an unbent position, and flexible ground arms integrally formed from a side wall having a contact portion adapted to be forced into contact with a ground strip on the printed circuit board to electrically connect the enclosure to ground, the contact portion of said arm formed at an edge of the arm generally in line with the side wall edge and moveable generally in a plane of the side wall, whereby the electromagnetic shield is held to the printed circuit board and electrically connected to a ground strip without the use of separate fasteners and solder.
