Patent ID: 7811102

Claim:
A connecting device for using in an electronic device, the electronic device comprising a housing, the housing comprising a bottom plate, a sidewall and a pivot shaft, the bottom plate comprising an inner surface, the sidewall extending substantially perpendicularly from the inner surface and defining an opening and a slot, the pivot shaft substantially extending perpendicularly from the inner surface and substantially aligned with the slot, the connecting device comprising: a driven gear disposed on the inner surface and defining a central pivot hole, the pivot shaft being inserted through the central pivot hole; a main body comprising a bottom surface and a lateral surface, the driven gear fixed to the middle of the bottom surface, the main body defining more than one connection port around the lateral surface, the radius of the main body being a little smaller than the distance between the pivot shaft and the opening; and a driving member engaged with the driven gear and protruding out from the slot, the driving member being operable to rotate the driven gear and the main body around the pivot shaft, thereby switching the connection ports to be exposed to the outside of the housing via the opening.
