Claims

[Claims for Utility Model Registration] 1. Notches of different shapes are provided on the flat opposing surfaces of each of the individual divided cores, which are made into a set of two, and the two divided cores having the notches are placed facing each other. An electromagnetic noise prevention core characterized by being combined and fixed together. 2. The electromagnetic noise prevention core according to claim 1,
A contact piece that comes into elastic contact with the core joining surface on one outer surface and a claw with the tip of the contact piece bent downward that fits into the edge of the notch are bent inward at the tips of both legs of the U-shaped elastic body. A core fixture characterized by being integrally formed. 3. A split core for forming an electromagnetic noise prevention core according to claim 1, characterized in that the core joining surfaces on both opposing surfaces have the same width, whereas the notches on the opposing surfaces have different shapes.
