In this embodiment, the rail 2 is used for supporting the printed board. The right lateral groove 2a in FIG. 1 of the rail 2 is used for originally supporting the printed circuit board, and the left lateral groove 2a is used for fixing the mounting member 10.

The mounting bracket 10 is formed by subjecting an iron plate to sheet metal processing. For example, a component mounting plate portion 11 for mounting a power transformer and the mounting bracket 10 for fixing the mounting bracket 10 to the base plate 5 are provided. Fixing plate portions (12, 13) formed at both ends of the component mounting plate portion (11) are provided.

The component mounting plate portion 11 is a flat plate shape, and as shown in FIGS. 2 and 3, for example, for mounting a power transformer, a screw hole 11a formed by burring and an insertion portion 11b formed by cutting and raising. And form.

A fixing plate portion 12 formed at one end of the component mounting plate portion 11
Is an edge plate portion 12a that fits in the lateral groove 2a of the rail 2.
have. The edge plate portion 12a is formed by bending one end of the component mounting plate portion 11 by bending and further horizontally bending the tip end side thereof. As shown in FIGS. 2 and 4, the edge plate portion 12a is formed with a bulging portion 12b protruding in the plate thickness direction. This bulge 12b
Is formed by pressing. The bulging portion 12b is for eliminating backlash when the edge plate portion 12a is fitted into the lateral groove 2a having a wide groove width for the printed circuit board, and has an apparent plate thickness T including the bulging portion 12b. Are formed to have a width substantially equal to the groove width of the lateral groove 2a.

On the other hand, the fixing plate portion 13 formed at the other end of the component mounting plate portion 11 has an abutting portion 13a that comes into surface contact with the base plate 5. The contact portion 13a is formed by bending up the other end of the component mounting plate portion 11 by bending and further horizontally bending the tip end side thereof. And this contact portion 13a
The protrusion 13b and one screw hole 13c are formed in the. The projecting piece 13b is formed by cutting and raising a part of the contact portion 13a toward the base plate 5 side, and is inserted into the engaging hole 5a formed in the base plate 5 as shown in FIG. By doing so, the base plate 5 is sandwiched. This piece

Further, the protrusion 13b in this embodiment extends in the direction along the lateral groove 2a of the rail 2 (the direction indicated by the arrow (a) in FIGS. 1 and 2).

Next, the operation of mounting the mounting bracket 10 on the base plate 5 will be described.

By sliding the mounting bracket 10 on the base plate 5 or the like, the edge plate portion 12a of the fixing plate portion 12 on one end side is fitted into the lateral groove 2a of the rail 2 while the fixing plate on the other end side is attached. Insert the projecting piece 13a of the portion 13 into the engaging hole 5a of the base plate 5, and then slide the entire mounting bracket 10 in the direction of the arrow (a) along the lateral groove 2a. It is restrained so that it does not float up from the plate 5, and the mounting bracket
10 is also movable in the arrow (b) direction perpendicular to the arrow (a) direction by fitting the edge plate portion 12a and the lateral groove 2a of the rail 2 and engaging the protruding piece 13a and the engaging hole 5a. Movements that rotate in the plane of the base plate are also constrained. Next, the fixing plate part on the other end side
If the only screw hole 13c provided in 13 is screwed, the movement in the direction opposite to the arrow (a) permitted by the mounting member 10 is also restrained, and the mounting member 10 is completely fixed to the base plate 5.

As described above, the mounting work of the mounting bracket 10 to the base plate 5 is performed by simply and easily sliding the mounting bracket 10 itself and then fixing the mounting bracket 10 at one place. Compared with the conventional mounting hardware that requires, the labor is significantly reduced and the workability is greatly improved.

Since the plate thickness of the iron plate used for the mounting bracket 10 is usually smaller than the plate thickness of the printed circuit board, the bulging portion 12b is formed in the edge plate portion 12a so as to be tightly fitted in the above embodiment. However, the mounting bracket 10 is thick and the horizontal groove 2a remains unchanged.
In the case of tightly fitting with, it is not necessary to provide the bulging portion 12b.

Further, in the embodiment, since the rail for supporting the printed circuit board is used, the edge plate portion 12a of the fixing plate portion 12 on the one end side is formed in a shape which is raised and bent so as to be at the height of the lateral groove 2a of the rail 2. However, it is not always necessary to use a rail for supporting the printed circuit board, and depending on the height position of the lateral groove of the rail, it can be left at the same height as the plate part 11 for mounting the component, and further, it should not be bent down. It is also possible to form. If the structure is a raised structure or a lowered structure, the strength of the fitting 10 itself can be increased.

Further, in this embodiment, the extending direction of the protruding piece 13b is set to the lateral groove 2a.
It is the direction along the arrow (direction of arrow (a) in FIG. 1), but
