FIG. 2 shows a conventional shield case for a printed circuit board, where c is a perspective view of the shield case, and d is a perspective view of a printed circuit board attached to the shield case. In FIG. 2c, the shield case 1 is a metal cylinder with a rectangular cross section, and at both corners of the upper part of one opening there are lowered parts 2 for attaching screws for fixing the board to the shield case.
1 and 22 are formed, and grooves 31 and 32 are formed on both side surfaces on the other opening side. In FIG. 2d, when the printed circuit board 4 is inserted into the shield case 1, the protruding parts 51 and 52 provided on the printed circuit board 4 are aligned with the grooves 31 and 32 provided in the shield case, and The lower parts 21 and 22 at the ends are screwed to fix the board to the shield case.

不都合があつた。 When using the shield case with the conventional structure shown in Fig. 2, it is necessary to form protruding parts 51 and 52 on the printed circuit board as shown in Fig. 2 d, and since the printed circuit board is generally cut out from a large board, The shape of the substrate is preferably rectangular, but the presence of the overhanging portions 51 and 52 causes disadvantages such as a complicated mold for cutting and waste of substrate material.

The present invention eliminates the drawbacks of the conventional shield case for printed circuit boards and provides a shield case that can be used for rectangular printed circuit boards. A part is extended in the length direction, a U-shaped groove is provided at the end thereof, the extension part with the U-shaped groove attached is bent at right angles to the side surface toward the opening, and the U-shaped groove is printed. It is characterized by being a guide groove on the board.

固定される。 In FIG. 1a, the shield case 1 is a metal tube with a rectangular cross section, and one step lower portions 21 and 22 are formed at both corners of the upper surface of one opening, and the other opening has lower portions 21 and 22 formed on both sides. Extending part 71,
U-shaped grooves 81 and 82 are formed in 72. 1st
Reference numerals 71 and 72 shown in FIG. As shown in FIG. 1b, the printed circuit board 4 is inserted into the shield case 1, and both ends of the printed circuit board 4 are aligned with the U-shaped grooves 81 and 82 provided in the shield case, and at the same time, the printed circuit board 4 is inserted into the shield case 1. It is fixed with screws at the lower parts 21 and 22 at the ends.

According to the present invention, the printed circuit board 4 and the shield case 1 have one end attached to the lower parts 21 and 22 with screws 6.
1 and 62, and the other end is inserted into the U-shaped groove 8.
1 and 82, there is no risk of the shield case 1 coming into contact with the circuit components mounted on the board and their lead terminals. Also, according to the present invention,
Since a U-shaped groove for guiding the printed circuit board is formed in the opening of the shield case, the protrusion 51 at the end of the printed circuit board, which was necessary in the conventional example, is eliminated.
52 is no longer necessary, and the printed circuit board can be a simple rectangle.
