ELECTROMAGNETIC SHIELD FOR A RADIOTELEPHONE

摘要

PURPOSE: Disclosed is an electromagnetic shield incorporated into a radiotelephone and having a series of spaced apart spring contacts that extend from the side wall for electrical contact with a ground trace on a printed circuit board. CONSTITUTION: The radiotelephone (30) includes a printed circuit board (48) having a ground trace (50) extending around an electrical circuit formed on the printed circuit board (48). The electromagnetic shield (10) is disposed adjacent the printed circuit board (48) for isolating the electrical circuit thereon. Forming a part of the electromagnetic shield (10) is a face, a side wall (14), and a series of spaced apart spring contacts (16) that extend from the side wall (14) for electrical contact with the ground trace on the printed circuit board (48). Disposed over the shield (10) is a housing structure that engages the shield and urges the shield against the printed circuit board (48) such that the spring contacts (16) thereof engage and make electrical contact with the ground trace of the printed circuit board.
