Japanese Patent JPH0572074

B2

An electrical connector for supplying electrical power to a machine at particular voltage and phase magnitudes selected, the connector having one part adapted to be mechanically and electrically connected to the machine and another part adapted to be electrically connected to a conductor providing the electrical power to be supplied. The connector comprises a plurality of pins on one of the connector parts and a corresponding plurality of mating slots on the other of the connector parts adapted to receive the pins when the connector parts are connected together. One of the pins and the corresponding one of the mating slots serve to complete a electrical ground circuit and have a fixed orientation independent of the selected voltage and phase magnitude for the particular connector. The remaining ones of the pins and slots are of a total number and have respective orientations unique to the particular voltage and phase magnitude selected for the connector, and the total number and orientations of the remaining pins and slots are fixed and non-changeable. The total number and orientations of the remaining ones of the pins and slots also are selected to prevent connection between either of the connector parts and a part of another connector of the same type as the connector but operative with different selected voltage and phase magnitudes.
