Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a printed wiring board support device, and particularly to a device for supporting a printed wiring board used not only for electrical devices but also for control circuits of mechanical devices and other electrical circuits.

In the past, printed wiring boards have often been easily inserted and removed into printed wiring board connectors along guides for convenience of maintenance, etc.; Some are arranged so that they can be attached and detached in one direction.

However, when it is not desirable to have parts that can be easily removed and repaired or inspected on the same surface and parts that are removed and removed in factories or for maintenance that requires advanced technology, etc., For example, there may be cases where it is desired to attach/detach a printed wiring board from both the front and rear sides because there is a separate operation section.

In addition, recently there have been many requests for different functions to be provided as options. They tended to be expensive.

This idea standardized the guide rail for inserting the printed wiring board, and also standardized the position for installing it.

The above-mentioned drawbacks were solved by making the structure for supporting the board common, and by making improvements such as making it possible to attach and detach the printed wiring board from both the front and rear sides.

The present invention will be explained in detail below with reference to the embodiments shown in the drawings.

FIG. 1 is a side view of a printed wiring board supporting device embodying the present invention, and FIG. 2 is a perspective view for explaining a printed wiring board supporting device embodying the present invention.

FIG. 1a shows a state in which a printed wiring board 1a is inserted into a printed wiring board connector 3a along a printed wiring board guide 2 (hereinafter referred to as a guide).
The guide 2 consists of three holes 5, 6.7 of the same pitch in one row of the flat plate 4.
Attach using two holes, 5 and 6.

Two holes 5' and 6' facing the two holes 5' and 6' of the same row of three holes 5', 6', and 7' of the same pitch in the flat plate 4' facing parallel to the flat plate 4 are used to form the guide 2'. Attach.

The grooves of guides 2 and 2' are parallel, and the holes 5 and 5' are parallel to each other.
Unless the lines connecting 6 and 6' are perpendicular to the flat plates 4 and 4', the printed wiring board 1a cannot be inserted smoothly.

Therefore, the flat plates 4, 4' have opposing holes 5 and 5', 6 and 6',
7 and 7' must be fixed in such a way that they face each other on a line perpendicular to the flat plate.

The holes 7, 7' remaining after installing the guide 2 or 2' are used for attaching and fixing the support 8 to the printed wiring board connector 3a.

FIG. 1 shows another embodiment, in which a printed wiring board 1b is attached to a metal support plate 9, and a connector 3b
A conducting wire connects the two.

This shows that various aspects can be adopted for the same purpose, and of course, the printed wiring board is only a small part and many other electronic components are attached to the support plate 9. It's okay.

Also shown in Figure 1 are three holes 5, 6.7 and 5' in one row. 6'
, 7', 6 and 7, 6' and 7' are guides 2 and 2.
The bottom of the tank is installed to facilitate attachment and detachment from the front side of the printed wiring board as shown in Figure 1a, and from the rear side in Figure 1A.

In order to explain these structures, they are shown in a perspective view in FIG.
, 6.7 (not shown) may be provided in multiple columns as shown in the figure, and holes are made at the intersections of three orthogonal rows and multiple columns.

The pitch of holes 5' and 6' or 6' and 7' between the rows is determined by guide 2.
holes 5' and 5' between each row at equal intervals according to the mounting hole dimensions of
, 6' and 6', and 7' and 7' have equal pitches and are appropriately determined according to the thickness of the printed wiring board, etc.

When the printed wiring board support device is configured as described above,
By standardizing the size of the printed wiring board or support plate, it is possible to use exactly the same flat plates 4 and 4', and the guides are also all common, so that the power supply and By standardizing the signal wiring, circuit parts of various types with any function can perform all their functions by simply replacing the printed wiring board. It has an excellent effect on
