Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a printed circuit board to a chassis, for example, and aims to facilitate the attachment work and to simplify the configuration.

As shown in FIG. 1, a conventional mounting device of this type fixes one end of a molded product 1 having a hinge mechanism to a fixed board 2 such as a chassis with a screw 3, while the other end of the molded product 1 is directly printed. One end of the printed circuit board 4 is fixed to the fixed board 2 by fixing it to the metal fittings fixed to the circuit board 4 or the printed circuit board 4 with screws 5, and the other end of the printed circuit board 4 uses the hinge mechanism of the finished product 1. The printed circuit board 4 was then rotated and fixed to a fixed board (not shown) located above the fixed board 2 with screws.

As a result, the printed circuit board 4 can be fixed vertically to the fixed board 2, but in this case, the finished product 1 is fixed to the fixed board 2 and the printed board 4 with screws 3 and 5, respectively, which improves workability. This has the disadvantage that it has poor performance and requires a large number of fixing parts.

The present invention eliminates the above-mentioned conventional drawbacks.

An example of this will be described below with reference to FIGS. 2 to 4.

In FIG. 2, a fixture 11 fixed to one end of a printed circuit board 10 is provided, one end of this fixture 11 is bent vertically to provide integrally protruding pieces 12, 13, and further, protrusions 12, 13 are provided. A retaining hole 14.15 is provided from the fixing member 11 to the fixing member 11.

Note that 16 is a screw for fixing the printed circuit board 10 and the fixture 11.

On the other hand, a fixed board 17 such as a chassis has one end bent vertically to form a mounting piece 18 integrally.
A pair of notch grooves 19, 20,
21 and 22 are installed in two places on the left and right.

As a result, the fixed board 17 and the mounting piece 18 mentioned above engage hole 1.
4 and 15 are provided at two locations.

The width of the engagement holes 14 and 15 is approximately equal to the fixed substrate 17 and the part of the mounting piece 18 that are inserted into the engagement holes 14 and 15, and the height thereof is approximately equal to the width of the fixed board 17 and the mounting piece 18. Dimensions) are the portion of the fixture 11 and the projecting pieces 12,1.
Both the heights of the portion at 3 are lower than the height of the mounting piece 18.

In the above configuration, when attaching the printed circuit board 10 to the fixed board 17, first attach the mounting piece 18 located between the notch grooves 19, 20 and the notch grooves 21, 22 to the fixing metal fitting 11.
．． Each is inserted into the engagement holes 14 and 15 provided in the projecting pieces 12 and 13, respectively.

In this case, as shown in FIG.
As shown in the figure, the printed circuit board 10 is connected to the fixed board 17.
The mounting piece 18 is inserted into the engagement holes 14 and 15 while the
It can also be inserted into.

In the state shown in Figure 3, leave the printer I/board 10 as it is.
The other end is fixed to another fixing board (not shown) with screws, either directly or via another fixing tool.

On the other hand, in the case of FIG. 4, the printed circuit board 10 is rotated in the direction of the arrow, and then the other end of the printed circuit board 10 is fixed.

Normally, there is no space in the direction perpendicular to the fixed substrate 17, so the fixed substrate 17 is first rotated in a parallel state as shown in FIG. 4, and then fixed.

In this way, according to the present configuration, the fixed substrate 1 of the fixed fitting 11
7 can be installed using the fixing bracket 11. without using screws.
Since this is done using the fixed board 17 itself, the workability is good and the number of fixing parts can be reduced.

Furthermore, during service, even if the printed circuit board 10 is rotated from the fixed state shown in FIG. 3 to the position shown in FIG.
．． 13 is engaged with the mounting piece 18, the printed circuit board 10 will not be accidentally removed from the fixed board 17.

As explained above, according to the present invention, a fixing metal fitting is fixed to one end of a printed circuit board, a protruding piece is integrally provided in the vertical direction on this fixing metal fitting, and an engagement hole is provided extending from the fixing metal fitting to the protruding piece. By providing a mounting piece vertically integrally with the fixed board and providing a pair of notch grooves extending from this mounting piece to the fixed board, the fixed board and the mounting piece are formed with a portion to be inserted into the above-mentioned retaining hole. The fixture and the fixing board can be joined together by the fixture and the fixing board themselves without using screws, which has the advantage of improving installation work and reducing the number of fixing parts.

In addition, when attaching the fixing bracket to the fixed board, fit the mounting piece into the retaining hole even when the fixing bracket is perpendicular to the fixed board or approximately parallel to the fixed board. It has the advantage that there are no restrictions on the mounting direction.

Furthermore, during service, even if the printed circuit board is rotated so that the fixing metal fittings are approximately parallel to the fixed board, the protruding piece and the mounting piece are still engaged, so the printed circuit board can be accidentally removed from the fixed board. This makes service work easier.
