Abstract
PURPOSE: To miniaturize the entire coil and to improve the reliability over a long time by combining the bobbin with the core so that the opening of bobbin is opposite to the yoke and by coating the winding and its terminal with a protective material.
CONSTITUTION: The terminal sheet 11 with a connection pattern is adhered to the core face not made contact with the yoke after the core 7 is coated with an insulating material to form an insulator film 10. Next, the bobbin 8 is attached to the core so that its opening 8a is not made contact with the yoke. The winding is provided to the bobbin, the terminal is drawn from the opening of bobbin to connect itself to the terminal sheet 11, the winding 9 and its terminals are covered with a protective material 12 such as a light curing coating material. In this way, the assembling process can be reduced, the coil can be miniaturized and the reliability can be improved over a long time since a short of the winding and corrosion of the end face are not produced.
