で係止して成るシールド箱構造。 A shield box that houses a printed circuit board on which electrical components are placed and fixed, and is constructed by fitting an upper cover with an inverted L-shaped plane part and one side, and a lower box with three bottom sides. In the structure, a plurality of through holes are provided near the three ends of the flat part, and a protrusion is formed by bending and hanging down each of the two side ends of the flat part so as to form a concave part at the same side end. and the upper cover having a concave notch provided at the other end of the same plane part, and a hook-shaped protrusion that fits into the concave part and the notch, respectively, at the tips of the three side surfaces. A first tongue piece part having a locking hole parallel to the bottom surface formed at the same tip, and a second tongue part protruding parallel to the bottom surface inside the two side parts are cut and raised. the printed circuit board is held between the second tongue portion and the protruding portion, and the engaging portion between the through hole and the locking hole is locked with a fastening member. Shield box structure.
