図6は従来の回路基板と枠体の接続構造に係る斜視図、図7は従来の回路基板と枠体の接続構造に係る要部断面図であり、次に、従来の回路基板と枠体の接続構造に係る構成を図6,図7に基づいて説明すると、枠体51は、箱形の金属材で形成され、開放部側に設けられ、棒状の凸部51aを残した状態で、凸部51aの両側に設けられた複数の切り欠き部51bを有する。   FIG. 6 is a perspective view of a conventional circuit board and frame connection structure, and FIG. 7 is a cross-sectional view of a main part of the conventional circuit board and frame connection structure. 6 and FIG. 7, the frame 51 is formed of a box-shaped metal material, is provided on the open side, and leaves the rod-shaped convex portion 51 a. It has a plurality of notches 51b provided on both sides of the convex portion 51a.

回路基板52は、外方に突出する複数の張り出し部52aと、この張り出し部52aの根本部に設けられた貫通孔52bを有すると共に、この回路基板52には、配線パターン53が設けられ、この配線パターン53の端部に設けられた接地用のランド部53aが張り出し部52aまで延びている。   The circuit board 52 has a plurality of projecting portions 52a projecting outward, and a through hole 52b provided in the base portion of the projecting portion 52a. The circuit board 52 is provided with a wiring pattern 53. A grounding land portion 53a provided at an end of the wiring pattern 53 extends to the overhanging portion 52a.

この回路基板52は、枠体51内に配置され、張り出し部52aが切り欠き部51b内に位置した状態で、凸部51aが貫通孔52bを貫通して、凸部51aとランド部53aが半田54付けされて、従来の回路基板と枠体の接続構造が形成されている(例えば、特許文献1参照)。
特開平11−121946号公報
The circuit board 52 is disposed in the frame 51, and with the protruding portion 52a positioned in the notch 51b, the convex portion 51a penetrates the through hole 52b, and the convex portion 51a and the land portion 53a are soldered. 54, a conventional circuit board-frame connecting structure is formed (see, for example, Patent Document 1).
