<p>PURPOSE:To eliminate the damage of the leads of starting and finishing ends of a cylindrical coil and a shortcircuiting ring to improve the reliability by covering the corners of the longitudinal and circumferential grooves of the core with guides. CONSTITUTION:A groove is formed at the same position as a circumferential groove 12b on a guide 11a. A signal coil 14 is wound in the groove 12b, and starting and finishing ends are engaged with the corner 11 b of the groove of the guide 11a to be connected through a longitudinal groove 12a to a terminal 13. Further, a circumferential groove 12c for containing a shortcircuiting ring 15 is formed between the grooves 12b in which the coil 14 is wound, and wired similarly to the coil 14 to be connected with the same terminal 13 and shortcircuited. Since the corners 12c of the longitudinal and circumferential grooves 12a, 12b of the core 12 are covered with the guide 11a formed integrally with or separately from a terminal board 11, the leads of the starting and finishing ends do not touch with the corners 12c of the core 12.</p> |
