Abstract: A power switch apparatus of universal serial bus device for protecting the universal serial bus device from electrical interference between a bus power mode and external power mode comprises a slide switch and socket door. The slide switch encased in the universal serial bus device selects either the bus power mode or the external power mode to serve as a unique power resource of the universal serial bus device by turning a control rod of the slide switch. The socket door assembled on the universal serial bus device has a pair of flanges protruding from an inner side of the socket door. The flanges is set at two sides of the control rod to turn the control rod to select the slide switch between the bus power mode and the external power mode, thereby preventing the universal serial bus device from the electrical interference.

Abstract: A plug connector is provided having a mechanism to lock with a mated socket connector and to enhance grounding. The plug connector includes a movable latch having a retractable claw. The claw is received within a corresponding recess in the socket connector in an inserted condition to prevent unintentional removal. The latch is movably mounted within a rigid conductive shell of the plug connector. The latch has a pressing portion that is accessible through a first aperture in the shell, and the claw projects through a second aperture. A latch spring is disposed in the shell to bias the latch outwardly. In an embodiment, the spring is unitarily formed with two free ends that are normally slightly offset from one another. The free ends pass over each other with a slight “click” interference when the latch spring is deflected. At an opposite side of the plug connector, a grounding spring projects outwardly from a recess in the shell for also contacting a recess in the mated socket connector.

Abstract: The present invention is for enlarging the moving stroke of a movable member according to rotation of a lever. Operation projecting portions for moving a contact holder are provided in a moderation piece provided in the base end portion of the lever, movably in the axial direction. When the lever is rotated in the arrow A direction, the moderation piece moves in the arrow B direction while sliding a cam surface. According thereto, the operation projecting portions press the inclined surface of guiding portions so as to move the contact holder in the arrow C direction. At the time, since the moving amount of the moderation piece in the axial direction can be added to the moving stroke L2 of the contact holder, the moving stroke L2 of the contact holder can be enlarged compared with the case with the operation projecting portions provided in the lever.
