Description

[Detailed Description of the Invention] The present invention relates to a top plate for supporting a printed board suitable for use in electronic equipment and the like.

Conventionally, as shown in FIGS. 5 to 7, this type of top plate 1 has a protrusion 1a at the tip fitted into a square hole 2a drilled in the casing 2, and a bent portion 1b at the upper end. was fixed to the housing 2 with screws or the like.

However, with such a structure, it takes a lot of time to process the top plate 1 and the square holes 2a of the housing 2, and furthermore, when a plurality of top plates 1 are arranged side by side, as shown in FIG. A gap 5 is formed between the adjacent top plate 1, which not only deteriorates the appearance of the device but also allows foreign matter to enter the interior through the gap 5, causing various troubles.

Therefore, the present invention is structured such that grooves and protrusions are formed on both sides of the top plate, and the grooves and protrusions are engaged between adjacent top plates to close the inside and outside of the casing. The object of the present invention is to provide a top plate for supporting a printed board which eliminates the above-mentioned drawbacks.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

As shown in FIGS. 1 and 2, the electronic device 6 is housed in a housing 2.
A plurality of guide rails 7 are fixed to the housing 2.

In addition, a support frame 2b is formed in the housing 2,
A stopper 2C is provided on the frame 2b.

On the other hand, a groove 7a is bored in the guide rail 7, and a printed board 9 is inserted into the groove 7a as indicated by the arrow A in FIG.
, are slidably engaged in the B direction.

A connector 10 connected to various circuit patterns on the printed board 9 is attached to the lower part of the printed board 9 in FIG. Plate 1 is fastened by screws 11, 11' via brackets NC, IC'.

The top plate 1 is formed into a plate shape as a whole, and furthermore, as shown in FIG. 1, grooves 1d and protrusions 1f are provided on both sides. 12 is provided to be detachably attached to the housing 2.

Since the present invention has the above-mentioned structure, the electronic device 8
When mounting the printed circuit board 9 in the housing 2 of , as shown in FIG. With the left end engaged with the groove 7a of the guide rule 7, the top plate 1 is lowered in the direction of arrow B in the figure until the lower end comes into contact with the support frame 2b.

When the top plate 1 and the frame 2b come into contact with each other, the printed board 9 to be mounted adjacent to the print board 9 is similarly engaged with the guide rail 7 as shown in FIG. At this time, the groove 1d of the top plate 1 of the printed board 9 and the protrusion 1f of the top plate 1 of the adjacent printed board 9 that is already in the mounted state
and the entire printed board is lowered in the direction of arrow B in FIG.

In this way, the printed boards 9 are successively inserted into the grooves 1 of the top board 1.
d and the protrusion 1f are engaged, and when the printed board 9 is inserted and engaged with all the guide rails 7, the holding plate 12 is attached to the housing 2 from above in the figure, and each The mounting work is completed by holding the top plate 1 under pressure between the holding plate 12 and the support frame 2b.

At this time, as shown in FIG. 3, each top plate 1 is connected with the adjacent top plates 1 through the groove 1d and the protrusion 1f, and the inside of the casing 2d is reliably closed off from the outside 2e. Ru.

Further, each printed board 9 is fixed in the horizontal direction in FIG. 2 by the groove 7a of the guide rail 7 and the stopper 2C, and in the vertical direction, that is, in the directions of arrows A and B, by the holding plate 12 and the support frame 2b. From, printed board 9
is reliably supported by the housing 2.

In the above embodiment, the groove 1d and the protrusion 1f have different shapes as shown in FIG. 1, but as shown in FIG. Of course, they may be formed into substantially symmetrical shapes.

As explained above, according to the present invention, the grooves 1d and the protrusions 1f are formed on the side surface of the top plate 1, and the grooves 1d and protrusions 1f of the adjacent top plate are engaged with each other, thereby controlling the inside and outside of the casing 2. Since the closure is ensured, there is no possibility that foreign matter or the like will enter the interior of the casing 2d from the gap 5 between adjacent front plates as in the conventional case, and it is possible to provide an electronic device 6 with a good appearance.

In addition, the top plate 1 can be mass-produced as a single piece by using aluminum or resin, and there is no need to process the square hole 2a on the housing 2, so assembly and processing are time-consuming. Therefore, it can contribute to lowering product prices.
