发明名称 PRODUCTION OF PIEZOELECTRIC BUZZER
摘要 PURPOSE:To easily bend a terminal without the positional deviation of the bending part to improve the workability of assembling by providing the stage where a terminal member between rear covers obtained by a resin molding is cut to a proper length and the stage where a notched part is used to bend the cut terminal member. CONSTITUTION:Terminal members A and B are arranged in parallel in a rear cover forming mold with a prescribed gap between them to form plural rear covers. Thereafter, the terminal member placed between rear covers 2 and 2' is cut into individual parts. With respect to the formed article after the end of this cutting stage, two terminals 3 and 4 are provided which are stood on the thick part of the rear cover 2 and has both sides extended to the outside. One side A1 of projected sides of the terminal 3 is bent into a V shape toward the side of a bowl-shaped projecting part 2B with the notched part as the boundary, and the other projected side A2 is bent at 90 deg. in the opposite direction with the notched part as the boundary. Thus, it is unnecessary to position bending parts again, and terminals are easily bent.
