Abstract

Abstract An electrical circuit comprises a source of electric current, a connector capable of conducting electricity, a first member to be connected to at least a second member, a fusible material incorporated with said connector, said first member disposed in said connector, means connecting said connector across said source to cause heating of said connector above the melting temperature of said fusible material to cause said fusible to flow into contact with at least said connector and said first member, and means including said connector for regulating the heat of said connector at about the melting temperature of said fusible material.
