Abstract

PURPOSE:To enable the control of mounting height of a mounting component and the engagement of a printed board with a case to be easily done without manual work by a method wherein the lead wires of the mounting component are formed into zigzags or doglegs by a bending work. CONSTITUTION:Mounting components 2a, 2b, and 2c whose lead wires 3a, 3b, and 3c are formed in zigzags or doglegs are inserted into mounting holes 5 of a printed board 4. At this point, the bent tips of the lead wires 3a, 3b, and 3c are made to bear against the upside of the printed board 4 to control a mounting height 9 of the mounting components 2a, 2b, and 2c to the printed board 4. Moreover, when the printed board 4 mounted with the mounting 2a, 2b, and 2c is engaged with a case 6, the board 4 bears surely against engaging parts 6a through the spring effect of the bent parts of the lead wires 3a, 3b, and 3c. By this setup, the engagement of the printed board 4 with the case can be easily made.
