Abstract: A shielding device (1) comprises a top cover (11) and a frame (10). The top cover comprises a body portion (110) and a plurality of flanges (111) extends downward from outer edges of the body portion. A dome shaped projection (114) is formed in a central portion of the flange (111). The frame comprises a narrow top wall (100) and a side wall (101) depending downward from an edge of the top wall. An ellipse shaped mounting hole (102) is formed through the side wall for detachably engaging with corresponding projection (114) to the top cover.

Abstract: An electrical connector for receiving a module (200) includes a shield (10, 11) defining a receiving space (104) for receiving the module, an FPC (3) received in the receiving space for electrically connecting the module and a support element connected to the FPC for maintaining an electrical connection between the FPC and the module.

Abstract: An electrical jack (100) for mating with an audio plug includes an insulative housing (1) defining a longitudinal central hole (101), a plurality of channels, and a pair of gaps communicating with the central hole. A plurality of conductive contacts are received in the channels and each has a contact section, a retention section secured in the channels, and a solder section extending out of the insulative housing. A grounding contact (3) with a top plate (35) and a pair of side plates (31, 33) encloses the insulative housing. Each side plate has a spring arm (311, 331) extending through the gap into the central hole thereby increasing the mating force with the mating plug.
