Embodiment
Present embodiment provides a kind of mobile terminal key assembly, adopts following technical scheme:
Described button assembly comprises and is arranged on the described portable terminal back side: adjust rotating disk, rotating shaft, lever, and sensitive switch;
Described adjustment rotating disk is fixed on the described rotating shaft, when described adjustment rotating disk rotates, drives the rotation of described rotating shaft and described lever, and the projection on the described lever triggers described sensitive switch.
Further, described button assembly also comprises: middle keycap, and the keycap below sets gradually in the middle of described metal clips conducting film (DOME) sheet, pcb board (Printed Circuit Board, printed circuit board (PCB)) and contact flat spring;
Keycap is fixed on the described rotating shaft mutually independently with described adjustment rotating disk in the middle of described;
When keycap was pressed in the middle of described, the described pcb board of described DOME sheet distortion back contact was connected the printed circuit on the described pcb board, realizes the conducting of described contact flat spring.
Further, described button assembly also comprises the retainer ring of fixing described rotating shaft.
Further, described middle keycap is fixed on the silica gel, when described middle keycap is pressed, transfers the pressure on the described DOME sheet by described silica gel.
Further, described contact flat spring is connected with described pcb board by FPC plate (Flexible Printed Circuit, flexible PCB).
The mobile terminal key assembly of present embodiment, power button and volume are adjusted the back side middle position that button all is arranged in terminal, power button adopts the DOME form, the adjustment of volume adopts dial rotation to adjust mode---and the handle that relies on volume to adjust on the rotating disk is pressed sensitive switch in rotation, reach the purpose of adjusting volume.
Adopt the mobile terminal key assembly of present embodiment, owing to changed the mode of directly pressing in the past, adopt to rotate and press, can directly not be loaded on the sensitive switch perpendicular to the pressure of disc surfaces, therefore be conducive to protect sensitive switch.The mode of operation of power button is the same with the button of common DOME form, just because keycap is hidden in below the volume button plane of rotor disc, general misoperation is difficult for causing power button to be activated, and can directly not be subjected to impulsive force in falling process, and reliability is improved.
