Abstract: An electromagnetic shield is incorporated into a radiotelephone. The radiotelephone includes a printed circuit board having a ground trace extending around an electrical circuit formed on the printed circuit board. The electromagnetic shield is disposed adjacent the printed circuit board for isolating the electrical circuit thereon. Forming a part of the electromagnetic shield is a face, a side wall, and a series of spaced apart spring contacts that extend from the side wall for electrical contact with the ground trace on the printed circuit board. Disposed over the shield is a housing structure that engages the shield and urges the shield against the printed circuit board such that the spring contacts thereof engage and make electrical contact with the ground trace of the printed circuit board.

Abstract: A shield can for radio frequency (RF) shielding of electronic circuitry mounted on or embedded in the surface of an insulating substrate such as a printed circuit board (PCB). The design of the shield can allows it to conform to variations in the surface of the PCB. The shield can, which is usually formed of metal, includes a top and a plurality of side walls dimensioned to completely cover the electronic circuity when the shield can is placed over the circuitry. According to the present invention, any of the sides of the shield can may be made to conform to the surface of the PCB (and to effectively contact a ground trace on the PCB) by providing a plurality of vertical slots in the side. The slotted side would then have a series of metal teeth each of which can be displaced angularly to the extent required to conform to the PCB when a modest force is applied to the top of the shield can.
