Abstract:
PURPOSE:To simplify the structure of a connector by directly connecting external connection wirings with terminal fittings mounted on a coil bobbin with a terminal base holder. CONSTITUTION:A rotor 14 is formed of a spacer 16 secured to a rotational shaft 12 and a permanent magnet 15 multipolarized on the outer periphery, coil bobbins 21, 22 in which polyphase coil 19, 20 are wound on stator yokes 17, 18 having many pole teeth oppositely to the magnet are contained to form a stepping motor. A terminal base 24 is provided at the flange of the bobbin 21, and terminal fittings 25 having a notch 30 are mounted on an upright portion 31. A terminal base holder 33 has two sets of spacers 34 for positioning to hold a plurality of external connection wirings 29 to be secured to the notch 35 of the yoke 17. Thus, when the wirings 29 are pressed into the notch 30, the coating 29b is coated by the notch to be electrically connected with core wirings 29a.
