Abstract
Abstract A structure for a terminal plug includes a thermoplastic resin base having a key boss and a plurality of protruding shafts formed integrally on a front side thereof. Terminal pins are formed on the plurality of protruding shafts by a chemical plating process. Connection patterns are disposed on the front side of the thermoplastic resin base and connected to said terminal pins, and circuit patterns are disposed on the back side of the thermoplastic resin base. A plurality of through-holes are formed in the thermoplastic resin base which electrically connect the connection patterns and the circuit patterns.
