Abstract
An assembly configured to protect a circuit board from electromagnetic interference. The assembly includes a metal shield and an enclosure. The metal shield includes a metal plate and a plurality of tangs. The plurality of tangs are spaced about and extend transversely away from at least a portion of a perimeter portion of the metal plate. The enclosure has a bottom wall and at least one sidewall disposed around a perimeter of the bottom wall, the at least one sidewall configured to urge the tangs of the metal shield inward when the metal shield is disposed in the enclosure.
Claims16
An assembly configured to be coupled to a circuit board for protecting the circuit board from electromagnetic interference, the assembly comprising:
- a metal shield for providing an electromagnetic interference shield, the metal shield comprising:
- a metal plate having a perimeter portion;
- and
- a plurality of tangs spaced about and extending transversely away from at least a portion of the perimeter portion of the metal plate, each tang including a bridge portion and a finger portion, the bridge portion having a first end attached to the perimeter portion and a second end spaced away from the perimeter portion and attached to the finger portion, the finger portion extending away from the second end of the bridge portion and being disposed at an obtuse angle relative to the bridge portion;
- and
- an enclosure having a bottom wall and at least one sidewall disposed around a perimeter of the bottom wall, the at least one sidewall including an inclined interior surface urging the tangs of the metal shield inward when the metal shield is disposed in the enclosure.
