をビス締めして結合したものである。 That is, the printed circuit board on which the power supply circuit components are mounted is slid into the cut-and-raised slits provided on both sides of the U-shaped chassis as a support member, and the opening of the U-shaped chassis is covered with a cover. The cover is joined at four points, two of which are joined by inserting and sliding the cut-out tongue piece of the chassis into the inverted L-shaped hole of the cover, and one point is where the sword-shaped tongue piece of the chassis is joined by the cut-out part of the cover. They are joined by inserting and sliding them upright, and at one point, the chassis, cover, and the printed circuit board are joined together by tightening screws.

作 用 本考案は上記した構造により、シヤーシとプリ

5 is a mounting screw, 5 is a cut-and-raised slit, 6 is a cut-and-raised section, 7 is a sword-shaped tongue piece, and 8 is a band-shaped cut and raised piece. To fix the chassis 1 and the printed circuit board 3, three slits 5 are formed by cutting and raising the chassis 1, and the printed circuit board 3 is inserted and slid into the slots, and the printed circuit board 3 is placed on a cut and raised flat plate 9 of the chassis 1 to support it.
