Patent ID: 8777644

Claim:
A plug with connecting device, comprising: a top housing having two bottom sheet slots and a connecting device extended from one side of the top housing for being connected to a power adapter, and said connecting device having plural ring-shaped slots; two copper contact rings, wherein one end of each of said copper contact rings being in a gradually-expanding shape and respectively received in said ring-shaped slots of said connecting device, the other end thereof being respectively a contact sheet extended perpendicular from the expanding shape, the contact sheets being received in the two bottom sheet slots; a retaining seat having a first retaining slot, a bottom of said first retaining slot being formed with a first positioning slot, a top of said first retaining slot being formed with a second positioning slot; an electrode sheet base having a pivotal shaft, one side of said pivotal shaft being formed with a positioning column, and one side of said pivotal shaft being received in said first retaining slot, two ends of said pivotal shaft being respectively installed with a switch seat, said switch seat being further formed with a seat hole, and the bottom of said seat hole being hollow; two electrode sheets, one end of each of said electrode sheets being formed with a stop sheet, the other end being formed with a wire hole, wherein said stop sheets being received in said seat holes and exposed outside said seat holes; and a bottom housing, capable to be engaged with said top housing, having a hollow chamber for accommodating said retaining seat, a bottom housing surface being formed with two housing slots respectively allowing said two electrode sheets to be exposed, the bottom of said housing slot being hollow, and the end section being formed with a plane hole, a second retaining slot being formed between said two housing slots for receiving the other side of said pivotal shaft; after being assembled, when said two electrode sheets being longitudinally rotated, said two electrode sheets are enable to be pivotally moved at the outside of said bottom housing, and said two electrode sheets being positioned through said positioning column being latched in said first positioning slot, meanwhile said stop sheets of said two electrode sheets being in contact with said contact sheets, thereby electrically conducting said plural ring-shaped slots and said two electrode sheets; wherein the top of said retaining seat is further formed with two first protrusions, the bottom thereof is formed with a second protrusion, and the fronts of said first protrusions and said second protrusion are respectively formed with an inclined surface.
