Claims

[Claims for Utility Model Registration] An E-shaped core, a shaped core fixed to the tip of this core, a primary coil fitted to the central leg of the E-shaped core, and a primary coil fitted to the central leg of the E-shaped core. A transformer comprising a secondary coil provided as a secondary coil, and a winding start end of the secondary coil is grounded to the E-type core, wherein the center leg and the side legs of the E-type core are integrated. A protective case made of synthetic resin that covers the end face of the secondary coil on the side of the continuous connection part, as well as the inner and outer peripheries of the secondary coil and insulates the secondary coil from the E-type iron core, is installed inside the case. The secondary coil is housed in the case, and is fitted and attached to the E-shaped core, and a ground terminal is attached to the inner surface of the inner cylinder through which the central leg of the case passes, and this ground terminal is connected to a metal having spring properties. It is made of a material and has a ground contact convex part that presses against the center leg in an elastically deformed state, and a coil attachment part that is separated from the center leg and to which the winding start end of the secondary coil is connected. A transformer characterized in that a winding start end portion of the secondary coil is grounded to the E-shaped core via this ground terminal.
