제8도 B는 제8도 A중의 선 8B-8B에 따른 단면도.FIG. 8B is a cross-sectional view taken along line 8B-8B in FIG. 8A. FIG.

Claims

An insulating substrate with two cutouts at the edge of the claim, a first conductor pattern in the form of a rough spiral with at least one turn, formed on the first surface of the substrate, and a second surface of the insulator Each of the first and second conductor patterns, comprising: a second conductor pattern of at least one number of turns; The ends of the print coils are electrically connected to each other through the through holes opened in the substrate, and the second ends of each of the first and second conductor patterns are electrically connected to the two connection terminals. .

The first conductor pattern of the shape of a rough spiral formed on the insulating substrate and the first surface of the substrate, and having at least one winding, and the shape of the rough spiral having at least one winding, formed on the second surface of the substrate. The second core pattern and the male thread suitable for the screw hole opened through the substrate at the central portion of the first and the second use patterns of the shape and the magnetic core inserted into the screw hole. And a first end of each first end of each of the first and second conductor patterns is electrically connected to each other through a through hole opened in the substrate.

Two connection terminals made of conductors filled in two cutout portions formed at the edges of the substrate are again provided so that each second end of the first and second conductor patterns is connected to one of the two connection terminals. Claim 2 print coil electrically connected.
