The toroidal coil with a terminal block according to claim 1, wherein the outer peripheral surface of the terminal block is provided with a plurality of flat end surfaces of chucking portions of the mounting machine.

[0006]

[Action]

 On the outside of the insulating cap made of resin material containing the toroidal core, attach the cap fitting part that has the positioning groove and hook receiving part, and inside the terminal block that stores and fixes the wound insulating cap, Attach the positioning groove that fits in the cap fitting section of the insulating cap, the positioning rod that fits in the hook receiving section, and the terminal block fitting section that has the fitting section hook attached, and connect the toroidal coil and the terminal block at each fitting section. Since the structure is combined and fixed, the lead wire protruding from the bottom of the terminal block is also positioned and fixed, and the mounting machine chucking part formed on the outer peripheral surface of the terminal block can be chucked by an automatic machine on the outer periphery of the terminal block. Use toroidal coil with terminal block.
