<p>PURPOSE:To make it possible to set an electric wire for detecting its current readily around the iron core of a shell type transformer in the opened state of a cap body by dividing the iron core of the shell-type transformer into the E-type core and the I-type core, and attaching the I-type core to the cap body. CONSTITUTION:When a current detecting device is attached to an electric wire for detecting a current, a cap body 31 is opened. The electric wire 51 is wound around a central iron core 15a of an E-type core 15 of a shell-type transformer 10. The electric wire 51 to be wound can be coupled into notch parts 53 and 55 which are provided on both sides of a checking projection piece 43 of a case body 21. When the cap body 31 is closed under this state, the electric wire 51 is clamped with the notch parts 53 and 55 and notch parts 57 and 59 provided in the cap body 31.</p> |
