The grooves 17 correspond to the installation positions of the grooves 17, and cooperate with the grooves 17, 17 so that a narrow circuit board can be loaded vertically. The side wall 22,
At the center of the upper end face of the housing 22, long grooves 28, 28 are projected in the longitudinal direction as shown in FIG. 8, respectively, and these long grooves are formed on the upper surfaces of the side walls 12, 12 of the housing 1. The projections 18 are fitted to the projections 18.

The connecting cylinders 13,... Of the housing 1 are shown in FIG.
As shown in FIG. 4, each of the connecting cylinders 23,... Of the lid 2 is in a positional relationship facing each other, and the threaded rods 4, 4 of the connecting means are screwed into the two connecting cylinders. Thereby, the storage section and the lid are connected.

Each of the end plates 3, 3 is provided with a respective fitting groove 14, 15, 24,
25 and is held.

Therefore, when a thin circuit board is loaded, the circuit board is placed on the pedestals 16,... Of the housing 1 and screwed, and the end plates 3, 3 are fitted to the housing 1. Groove 1
4 and 15, where both side walls 22, 22 of the lid 2 are fitted.
When the end faces of the side walls are brought into contact with the side walls 12 of the housing 1 from above and the end faces of the side walls are brought into contact with each other, the end face plates 3, 3
The upper end of the cover 2 fits into the fitting grooves 24 and 25 of the lid 2, and at the same time, the end surfaces of the distal ends of the connecting cylinders 13 and 23 abut against each other. It will be in the state fitted in the long groove 28. Therefore, as shown in FIG.
Are screwed upward from the lower surfaces of the connecting cylinders 13, 13 to connect the storage unit 1 and the lid 2, thereby fixing the whole in a box shape.

Next, a case where a circuit board incorporating a high circuit element and a lamp is mounted will be described with reference to FIGS.

In this configuration, since the configurations of the housing 1 and the lid 2 are the same as those described above, the description is omitted. In this case, instead of the end plates 3 and 3, end plates 5 and 5 for height adjustment and side walls 6 and 6 for height adjustment are used.

The heights (widths) of the end plates 5, 5 are
3 is higher than the height of the end plates 3 and 3 but can be fitted into the fitting grooves 14, 15, 24 and 25 between the housing 1 and the lid 2. is there.

The height adjusting side walls 6 and 6 have a difference in height between the end plates 3 and 3 and the height adjusting end plates 5 and 5, as shown in FIG. , Can be interposed between the end surfaces of both side walls 12 and 22 of the storage body 1 and the lid body 2,
As shown at 0,13,14, two connecting cylinders 61,61 are formed respectively. As shown in FIG. 15, the lower part of the connecting cylinder parts 61, 61 is an enlarged cylinder part 62, and the cross-sectional shape of the enlarged cylinder part is shown in FIG. The distal end of the connecting tube 13 of the housing 1 can be inserted. And the connecting cylinder 61
Are vertically arranged as shown in FIG.
After being connected to the connecting cylinder portions 13 and 23, the screw rod 4 serving as a connecting means is screwed into and can be penetrated.

As shown in FIGS. 15 and 16, projections 63 are formed on the upper end surfaces of the side walls 6 and 6 in the longitudinal direction, and long grooves 64 are formed on the lower end surfaces in the longitudinal direction. As shown in FIG.
2 can be fitted into the long groove 28 of the lower end surface of the side wall 22 of the lid 2. Further, fitting grooves 65, 65 are formed at both ends of the side walls 6, 6, and the fitting grooves are continuous with the fitting grooves 14 of the housing 1 and the fitting grooves 24 of the lid 2. In addition, the end face plates 5 and 5 for height adjustment can be fitted.

Therefore, when a thick circuit board is loaded, the circuit board is placed on the pedestals 16,... Are fitted into the fitting grooves 14 and 15 of the housing 1 and the fitting grooves 65 and 65 of the side walls 6 and 6, and there are two side walls 22 and 2 of the lid 2 there.
When the end faces of the side walls are brought into contact with each other so as to be aligned with the upper side of the side wall 6, the upper ends of the end face plates 5, 5 are fitted into the fitting grooves 24, 25 of the lid 2, and at the same time, Tube parts 13, 6
The end surfaces of the leading ends of the first and second 23 also come into contact with each other. Then, as shown in FIGS. 11 and 12, the screw rod 4 is screwed upward from the lower surface of the connecting cylinders 13 and 13 of the housing 1 and further penetrated through the cylinder 61 of the side wall 6 so that the lid 2 is Connection tube 23
The storage unit 1 and the lid 2 are connected by being screwed into the inside.

It should be noted that the end face plate 5 and the side wall 6 for height adjustment are
The structure is not limited to one sheet on one side, and a plurality of sheets may be stacked on the same plane in the vertical direction.

[0020]

As described above, according to the present invention, the end plate for adjustment and the side wall for adjustment can be omitted according to the different height of the circuit board depending on the circuit elements or lamps installed, It is excellent in versatility because a box most suitable for loading the circuit board can be constructed by using the box.
