Method of connecting aluminum wire to electrical terminals
Abstract
Abstract A method of connecting conventional electrical terminals having at least non-aluminum portions, such as nickel-plated steel, to solid or stranded aluminum wire so that aluminum oxide on the surfaces of the strands does not prevent a satisfactory electrical contact. Such conventional terminals have a channel portion with extending tabs so that the wire can be placed in the open channel and the tabs crimped to close the channel and hold the wire in electrical connection with the terminal. According to this invention, after the aluminum wire is held by crimping, the solid or stranded wire is then ultrasonically welded to the channel portion to remove the oxide already on the aluminum wire and preclude any further build-up of aluminum oxide.
