Claims

[Scope of utility model registration request]

(1) Consists of an iron core, a secondary coil wound around the iron core, a primary coil edgewise wound with a conductor having a rectangular cross section, and a molding member for molding at least this primary coil, In the case where the winding width of the coil is larger than the width of the terminal of the primary coil in the winding width direction, the lead terminal of the primary coil has a protruding portion that protrudes from the surface of the mold member and a primary coil projection. and a connecting portion welded to the conductor, and the protruding portion and the connecting portion are integrally formed so that the center of the protruding portion and the center of the winding width of the primary coil substantially coincide with each other. molded current transformer.

(2) The protruding part of the lead terminal is formed into a cylindrical shape, and a screw hole is formed approximately in the center of the protruding end surface of the protruding part, and the center of this screw hole is aligned approximately with the center line of the primary coil winding width. The molded current transformation according to Claim 1 of the Utility Model Registration Claim, in which the connecting portion is formed into a prismatic shape, and one end surface of the prismatic connecting portion is welded to the inside of each lead conductor of the primary coil. vessel.
