  • Patent number: 5556308
    Abstract: The present invention is a metal blade formed of folded strips (13, 14) for an assembly of electrically conductive contacts in a printed circuit board, adapted to access line current, such as in a 120 V AC outlet. The assembly may be used in various ways such as an intermediate in the making of molded plugs. The blades are adapted for fabrication in a progressive stamping operation and for automation in use from a roll or hopper. A blade of the present invention has resilient tabs (21) and spaced away sharp edge fingers (16). The tabs are formed to snap engage in a tapered slot (26) in a printed circuit board with the sharp edges (17) of the fingers (16) in electrical contact with a printed circuit and to hold its engagement even before being soldered. Each of the folded strips includes pad (12) and a section of a bubble (15) formed to prevent flashing of plastic during a molding process.
