ABSTRACT: Selectively Plating Interior Surfaces of Loose Piece Electrical Terminals. An apparatus for continuously plating interior surfaces of loose piece electrical terminals is characterized in that loose piece terminals are continuously fed to a continuously rotating mandrel, are held against the mandrel, during the plating process by retaining means, and are released from the mandrel, the mandrel having a plurality of anode extensions and associated nozzles therein, the anode extensions being mounted for reciprocation into and out of the interior receptacle portion of the terminal s that are against the mandrel. A conduit supplies plating solution under pressure through the nozzles and upon the anode extensions and into the interiors of the terminals in which the anode extensions are received. The retaining means is an elongated resiliently mounted member which surrounds a portion of a rotating mandrel whereby the loose piece terminals are held against the mandrel during the plating process wherein the anode extensions move into the interiors of the terminals, plating solution is injected over the anode extensions, and the anode extensions are retracted from the terminals, the terminals being released from the mandrel after the anode extensions have been retracted and the terminals have passed the end of the retaining means. A process for selectively plating the interior surfaces of electrical terminals and electrical terminals plated according to the invention are also disclosed.
