Abstract
Abstract The electrical connections to the main winding and the auxiliary winding of an induction motor are made with three identical terminals, each of which has one wire-receiving slot means dimensioned to receive the wire of the main winding and another wire-receiving slot means which is dimensioned to receive the wire of the auxiliary winding. A terminal housing is used which has three cavities, one for each of the terminals. The housing has a wire-admitting slot means communicating with the first cavity which receives only one end of the main winding, a wire-admitting slot means which communicates with the second cavity and which receives only one end of the auxiliary winding. Two wire-admitting slots communicate with the third cavity and these slots receive the other ends of the main and auxiliary windings. Three identical terminals are crimped to lead wires so that when the terminals are inserted into the cavities, the required electrical connections will be made to the main and auxiliary windings of the motor.
