PURPOSE:To enable parts to stand by itself without inclination at the time of solder dip and to eliminate the foreign sounds due to rubbing of the contact face against a board by providing a notch in a part of a positioning tongue piece. CONSTITUTION:When vibrator electronic parts are mounted on a printed board 24, vibrator electronic parts are temporarily fixed to the printed board 24 without being inclined by positioning tongue pieces 21 and 22 and two lead terminals 23. Tongue pieces 21 and 22 are provided with notches 25 and 26. At the time of solder dip, lead terminals 23 are soldered to the printed board 24, and vibrator electronic parts are fixed to the printed board 24. Notches 25 and 26 of positioning tongue pieces 21 and 22 are cut after solder dip, thereby removing parts 29 and 30 lower than notches 25 and 26 of positioning tongue pieces 21 and 22. Thus, contact parts between positioning tongue pieces 21 and 22 and the printed board 24 are eliminated. Consequently, foreign sounds for vibration of vibrator electronic parts are eliminated. |
