Abstract: An electronic device includes a housing, a circuit board, a display having a plug, a jack defined in the circuit board, a locking plate releasably fixed to the housing. The jack is electrically connected to the plug so the display is electrically connected to the circuit board. After a plug is inserted into the jack, the locking plate is fixed to the housing to impact the plug, thereby preventing the plug from disconnecting from the jack.

Abstract: A key pad assembly includes a keypad and a shading sheet. The keypad includes a board and a plurality of supporting portions formed on and protruding from the board, each supporting portion has an end surface for pressing and sidewalls surrounding and connecting to the end surface and the board. The shading plate includes a base sheet attaching to and shading the board and a plurality of shading cavities formed on the base sheet, the shading cavities surrounds and shades the corresponding supporting portions while allowing light to pass through the end surface.

Abstract: A cover mechanism for an electronic device includes a protective cover and a support member. The support member is latched to the electronic device, and defines two slots. A plurality of projections formed in each slot. The protective cover includes a cover portion, and two axles. The axles are rotatably received in the slots. Each axle includes four ridges. The four ridges of the protective cover are deformedly latched in the slots to position the protective cover relative to the support member in different positions.

Abstract: A cover latching mechanism includes a housing, a cover, a button and a spring. The button is slidably mounted to the housing and releasably latches with the cover. The spring is mounted between the button and the housing. When the button is pressed, the button slides relative to the housing to compress the spring and release the button from the cover.
