Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printed circuit board mounting device for electrical equipment.

[Conventional technology]

A conventional printed circuit board mounting device for electrical equipment has a structure as shown in FIG.

A plurality of support pieces 3 having claws 3a that engage with the peripheral edge of the first printed circuit board 2 are integrally provided at the end of the holder 1, and the claws 3a of the support pieces 3 are attached to the first printed circuit board 2.
It has a structure in which the first printed circuit board 2 is vertically supported by being engaged with the peripheral edge of the first printed circuit board 2.

If the second printed circuit board must be mounted horizontally and near the first printed circuit board 2 due to mechanical design, the first and second mounting angles 4 and 5 are installed separately from the holder 1. A second printed circuit board 8 is attached to the first and second mounting angles 4 and 5 using first and second mounting screws 6 and 7.

[Problem that the invention attempts to solve]

In the conventional technology, the second printed circuit board 8 cannot be directly mounted on the chassis, but has a structure in which it is mounted using the first and second mounting angles 4 and 5. It has to be relatively long, making attachment of the second printed circuit board 8 structurally unstable. Further, since the first mounting angle 4 is a separate part, it is not practical because it increases the cost in terms of assembly work, number of parts, and parts management.

[Means for solving problems]

In the present invention, a plurality of support pieces 9, 10, 11 having claw parts 9a, 10a, 11a are provided on the holder 1, and the claw parts 9a, 10a, 11a of the support pieces 9, 10, 11 are
is engaged with the first printed circuit board 2 to vertically support the first printed circuit board 2. Support pieces 9 and 11 are provided at a predetermined interval in the vertical direction, and a second printed circuit board is provided between the claw portion 10a of the one support piece 10 and the claw portions 9a and 11a of the other support pieces 9 and 11. It has a structure in which one end of 8 is inserted and supported, and it is installed horizontally.

[Effect]

According to such means, the claw portion 10a of one support piece 10 and the claw portions 9a, 11 of the other support pieces 9, 11
One end of the second printed circuit board 8 can be inserted and supported between the second printed circuit board 8 and the second printed circuit board 8, and the second printed circuit board 8 can be mounted horizontally.

Therefore, the first mounting angle 4 and the first mounting screw 6 in the conventional example are no longer necessary, and the work of tightening the first mounting screw 6 is also no longer necessary.

〔Example〕

This will be explained with reference to FIGS. 1 and 2. In the figure,
Parts equivalent to those of the conventional example in Fig. 3 are given the same reference numerals.
The explanation will be omitted.

FIG. 1 shows a first embodiment.

Reference numerals 9, 10, and 11 denote first, second, and third support pieces that are integrally provided at predetermined positions of the holder 1, and have claw portions 9a, 10a, and 11a that protrude in the horizontal direction, respectively.
are integrally formed.

The thickness of the second printed circuit board 8 is oriented perpendicularly to the first, second and third support pieces 9, 11 among the first, second and third support pieces 9, 11. and vertically shifted by the same dimension.

The first, second and third support pieces 9, 10 and 11 are inserted into the first, second and third holes 12 and 1 of the first printed circuit board 2.
3 and 14, and the claw portions 9 are inserted into the peripheral edges of the first, second, and third holes 12, 13, and 14, respectively.
a, 10a, and 11a are engaged to support the first printed circuit board 2 vertically.

One end of the second printed circuit board 8 is fitted between the first and third support pieces 9, 11 and the second support piece 10, and the other end is supported by the second support piece 10. A second printed circuit board 8 is mounted horizontally by attaching it to the mounting angle 5 with a second mounting screw 7.

FIG. 2 shows a second embodiment.

Claw portions 9a, 11 of first and third support pieces 9, 11
a facing upward, and by forming the claw portion 10a of the second supporting piece 10 facing downward, the first, second and third supporting pieces 9, 10, 1
The claw parts 9a, 10a, 11a of the first part and the flat part on the opposite side are made to face each other, and a second part is placed between these flat parts.
One end of the printed circuit board 8 is inserted and supported.

In the case of this embodiment, the claw portions 9a, 10a, 11a of the first, second, and third support pieces 9, 10, and 11 are regulated by the second printed circuit board 8 so as not to move in the vertical direction. Therefore, the claw parts 9a, 10a, 11
a does not come out of the engaged state, and the attachment of the second printed circuit board 8 becomes stronger.

[Effect of idea]

The present invention eliminates the need for the first mounting angle 4 and the first mounting screw 6 in the conventional example. Since it can be supported by simply fitting one end of the support piece between the plurality of support pieces 9, 10, 11, costs are reduced in terms of assembly work, number of parts, parts management, etc., and it is practical. This has the effect of making the attachment of the second printed circuit board 8 structurally stable.
