Claims

[Scope of utility model registration request]

A coil is wound around a bobbin that has flanges at least on both ends, and an L-shaped terminal is planted adjacent to the pull-out groove for pulling out the coil lead wire on both ends of the flanges or one side of the flanges, and one side of the L-shaped terminal is installed. The lead wire is passed through the lead groove and connected by soldering, and the other side of the L-shaped terminal is provided with a tapered part at the tip and a fixing groove or a fixing convex part perpendicular to the axial direction on the side surface to cover the external lead wire. A tube that has a piece that connects the core wire, a fixing claw that fits into the fixing groove or fixing protrusion on the side surface of the tip, and a concave part that fixes the fixing claw and the connecting piece provided in an insulating case made of a molded product. A transformer is constructed by attaching a shaped connection piece and incorporating a magnetic core into the center hole of the bobbin.
