    • A snap-fit shield is provided which fits securely within a frame opening, and which shields and grounds the opening while eliminating a need for a complementary connector portion. The shield has an insulative inner housing having a first base wall and a first pair of side walls and end walls extending therefrom defining a first cavity. The shield includes a conductive shell having a second base wall and a second pair of side walls and end walls extending therefrom defining a second cavity. The second pair of side walls and end walls have at least one outward bias positioned thereon. The shield also has an insulative outer housing having a third base wall and a third pair of side walls and end walls extending therefrom defining a third cavity. The outer housing is configured to snap-fit within an opening in a frame so as to shield circuitry internal thereto. The third cavity of the outer housing is configured to receive at least a portion of the conductive shield therein, while the second cavity of the conductive shield is configured to receive the inner housing therein.
    • 提供了一种卡扣式护罩,其牢固地配合在框架开口内,并且在不需要互补的连接器部分的情况下屏蔽和接合开口。 屏蔽件具有绝缘内壳体,该绝缘内壳体具有第一底壁和从其限定第一腔的第一对侧壁和端壁。 屏蔽包括具有第二底壁和第二对侧壁的导电外壳和从其延伸的端壁限定第二腔。 第二对侧壁和端壁具有定位在其上的至少一个向外偏压。 屏蔽还具有绝缘外壳,其具有第三底壁和第三对侧壁以及从其限定第三空腔的端壁。 外壳被构造成卡扣配合在框架中的开口内,以便屏蔽内部的电路。 外壳体的第三腔被配置为在其中容纳至少一部分导电屏蔽件,而导电屏蔽件的第二腔体构造成在其中容纳内壳体。
