  • Patent number: 4412201
    Abstract: A coil assembly, in particular for shaded-pole motors, in which at least one edge of a coil form flange has a molded connecting pocket (typically 4, 5, 6, 7) containing groove (18) by snap-in type of covers (8), with one end of the groove (18) containing a recess (cavity 23) and a blind bore (20). A conductive member connecting sleeve (11) is inserted into the blind bore (20), the sleeve being of tubular construction at its end opposite the blind bore. The sleeve includes a conductive pin (13) projecting at a right angle, and has a narrow (taper) (22) producing a "weak" point (taper) about which the sleeve is bent into the recess. Pin (13) has an end of the winding attached thereto before sleeve 11 is bent, such that the connection is enclosed in the recess. Attachment of a Litz wire (pigtail) is by crimping into the end of the sleeve. The Litz wire lays in the groove and is captured by teeth (14) which bite into its insulation from the inside surface of the cover (8) thereby providing strain relief.
