Patent ID: 7012204

Claim:
A silver contact fixing structure for conductive blades comprising a conductive blade which has a fastening section for holding a silver contact; wherein the fastening section has a first fixing zone and a second fixing zone on a vertical surface corresponding to the conductive blade that connects to each other, the first fixing zone being greater than the second fixing zone and forming a bucking end on the juncture of the first fixing zone and the second fixing zone, a silver wire being pressed and filled in the fastening section to form a silver contact which is shaped as the fastening section to be retained by the bucking end to form a strengthened fixing, the silver contact structure is formed by a fabrication method which comprises the steps of: A. stamping a blank by stamping the conductive blade with a first upper mold to form the first fixing zone; B. stamping the blank for a second time by stamping the conductive blade with a second upper mold which is smaller than the first upper mold to form the second fixing zone which is smaller than the first fixing zone; and C. planting the silver wire by placing the conductive blade on a first lower mold, and placing the silver wire in the fastening section formed by the first fixing zone and the second fixing zone, and pressing and filling the silver wire in the fastening section through a third upper mold.
