Abstract
An electric plug includes a casing, two metal contacting blades, a printed circuit board and a cap. The casing has a cavity defined in the casing. The two metal contacting blades are mounted in the casing and extend out from the casing. The printed circuit board is received in the cavity in the casing and has two metal clampers electrically connecting with the printed circuit board. Each clamper has two legs mounted on the printed circuit board and curved toward each other for securely clamping the contacting blade between the two legs and electrically conducting the contacting blade with the printed circuit board. The cap is mounted on the casing for closing the cavity in the casing. The clampers provide a high heat-resistance. The connections between clampers and the contacting blades are firm for providing a well conduction without wire or welding.
