Abstract: An electrical connector retention device for retaining a connector on a circuit board comprises a mounting portion connected to a housing of the connector and an engaging portion received in an aperture of the circuit board. The engaging portion comprises first and second legs each having left and right interfering portions positioned at different vertical levels. The interfering portions on the same sides of the first and second legs are also positioned at different vertical levels. When the connector is mounted to a circuit board having a smaller thickness, the interfering portions of the engaging portion positioned at a high vertical level engage with a periphery of the aperture of the housing to establish reliable engagement therebetween.

Abstract: A shield panel includes a substantially flat plate adapted to be snugly fit into an opening defined in a casing of an electronic device for shielding a circuit board inside the casing. Two board support arms extend from the flat plate. Each board support arm defines an elongate slot extending in a direction substantially normal to the flat plate having a distal end, a proximal end, and two edges extending between the ends for receiving and guiding an edge of the circuit board from the distal end to the proximal end. One of the edges of the slot is declined with respect to the other edge for accommodating a variation of an angle formed between the flat plate and the circuit board.

Abstract: An electrical connector includes an insulative housing retaining signal and power contacts therein. A resettable power regulation device is attached to the housing and electrically connected to the power contact whereby an excessive-power condition caused by an excessive-current or excessive-voltage power signal transmitted through the power contact triggers a shut-down operation of the regulation device thereby terminating transmission of the power signal to protect an electrical device connected to the connector. The resettable power regulation device resumes transmission when the power condition decreases to an operational level.
