Abstract
A universal motor connector unit is usable with different three phase and single phase motors for connecting the motors to different incoming voltages. The connector has a motor-mounted connector unit with 15 socket terminals and contacts in a fixed 3.times.5 matrix array. A complementing plug-in connector unit has pin contacts in a similar matrix and with U-shaped connections between the pin contacts. In a three phase connector, 12 pin contacts are in a 3.times.4 matrix. The plug-in unit in one orientation establishes a first winding connection for one voltage and when rotated 180.degree., a second voltage. The connector may also be used to change direction of rotation rather than voltage selection. For a single phase motor, the socket connector is the same as for the three phase motor. The plug-in unit is formed with separate plug-in elements; one is provided for voltage selection and a second for rotation selection. The various parts can be specially encoded to prevent insertion of the voltage selection unit into the rotational selection part and/or insertion of the rotational selection part to the voltage selection terminals of the socket member.
