Abstract:
An electromagnetic interference (EMI) shield apparatus comprising:a housing including an inner region and an opening formed therein, at least one electronic device positioned in the inner region, a portion of the at least one electronic device extending through the opening, the housing including a top wall including an inner surface, a bottom wall including an inner surface, and a side wall including an inner surface, a cover positioned in the inner region of the housing and secured to the inner region of the housing, the cover including a body portion, the body portion including a top longitudinal side, a bottom longitudinal side, a first end wall portion and a second end wall portion, a first deflectable flange portion extending continuously along the top longitudinal side for contacting the inner surface of the top wall of the housing, a second deflectable flange portion extending continuously along the bottom longitudinal side for contacting the inner surface of the bottom wall of the housing, a third deflectable flange portion extending continuously along the first end wall portion for contacting the inner surface of the side wall of the housing, and a fourth deflectable flange portion extending continuously along the second end wall portion for contacting the inner surface of the side wall of the housing to allow a force applied in a direction substantially perpendicular to the body portion to deflect the first, second, third and fourth deflectable flange portions and bias the first, second, third and fourth deflectable flange portions against the inner surface of the top wall, the inner surface of the bottom wall, and inner surface of the sidewall to form a positive contact between the first, second, third and fourth deflectable flange portions and the inner surface of the top wall, the inner surface of the bottom wall, and the inner surface of the sidewall thereby preventing electromagnetic radiation from exiting the housing.
