ABSTRACT:
A molded end coil insulator designed for attachment to a ferromagnetic core and which forms part of the ground insulation for magnet wires wound thereabout and about a series of pole pieces formed on the core. The end coil insulator includes features which improve the adaptability of the resulting device to automated winding of the magnet wires and connection of lead wires from an external circuit with the magnet wires. One such feature is an improved terminal support which receives and retains a terminal member in good electrical contact with a magnet wire, and which positively grips a lead wire from an external circuit in such a manner that a section of the lead wire connected with the terminal member is effectively isolated from strains and vibrations in the external circuit. Another feature of the molded end coil insulator is structure for positively restraining and guiding crossover sections of magnet wires which extend between the pole pieces. Still further features of the end coil insulator are its design for good heat transfer contact with the core, and its structure for retaining sheets of insulating material in openings in the core between the pole pieces.
