FIG. 2 shows a state where the printed circuit board 14 is inserted into the connector 12, and FIG. 2 shows a state where the printed circuit board 14 is not inserted into the connector 12 and the connector port 12 a is visible. Also, on both sides of the connector 12, L
Printed circuit board 1 with slide board guide 15 shaped like a letter
4 is provided with a slide guiding portion 16 for guiding sliding in the width direction. The width of the printed circuit board 14 corresponds to the distance between two opposing sides sandwiching the inserted side when the side of the printed circuit board 14 inserted into the connector port 12a is referred to as an insertion side, and is referred to as its width direction. Means the length direction of the insertion side. Further, the height of the printed board 14 corresponds to the length of two opposing sides sandwiching the insertion side of the printed board 14. The slide board guide 15 has a board guide forming section 18 on which a board guide 17 to be paired with the board guide 11 is formed, and a slide section 19 for moving the board guide forming section 18.
a is formed symmetrically with respect to the center line in the longitudinal direction of a.
Here, the engagement portion between the connector 12 and the slide board guide 15 will be described in detail.

A plate portion 20 is provided at a portion of the slide portion 19 which forms a part of the slide board guide 15 and engages with the slide guide portion 16, and faces the slide guide portion 16 of the plate portion 20. A V-shaped uneven groove 21 is formed on the surface. On the other hand, the T-shaped groove 2
2 is provided in the length direction of the connector 12, and this structure guides the sliding of the plate portion 20 and prevents the slide board guide 15 from coming off the slide guiding portion 16. In addition, V-shaped concave and convex grooves 23 having the same pitch are formed on a surface of the slide guiding section 16 facing the V-shaped concave and convex grooves 21 formed in the plate portion 20. This V-shaped uneven groove 2
A slide board guide locking mechanism that locks the slide board guide 15 is formed by 1 and 23. Each of the V-shaped concave and convex grooves 21 and 23 has a pitch
7 are smaller than the depth d of the guide groove 17a, and are formed in the entire length direction of the connector 12 and the length of the plate portion 20, ie, the slide portion 19, respectively.

The feature of this embodiment is that the connector 1 is provided with a structure for sliding the board guide 17 and a mechanism for locking the movable board guide 17.
Since it is integrally molded with 2, the support mechanism for the printed circuit boards 14 having different widths can be realized by two parts. As a result, the assembly of the support mechanism can be made relatively inexpensively, and the size and weight of the electronic device can be reduced.

Next, the operation of this embodiment will be described with reference to FIG. Note that members that are not necessary for description are omitted as appropriate from each drawing.

First, in the state shown in FIG. 5A where the connector 12 and the slide board guide 15 are separated, FIG.
As shown in (b), the tip of the slide portion 19 of the slide board guide 15 is applied to one end of the connector 12, and the slide board guide 15 is pushed in the direction of arrow B. Connector 1
5 and the slide board guide 15 come into contact with each other on the slopes of the V-shaped concave and convex grooves 21 and 23 as shown in FIG. 5B, but when further pushed, as shown in FIG. The slide portion 19 whose tip is broken by the pressing force is V
While sliding on the slope of the concave-convex groove 23, it is deflected in the direction of arrow C, that is, outwardly by its spring property. Further, when the slide board guide 15 is pushed in the direction of arrow B, the V-shaped concave / convex
The top of the convex portion of the V-shaped concave / convex groove 21 crosses over the top of the third convex portion. Then, the slide portion 19 returns to the original state due to its spring property, and the V-shaped concave and convex grooves 21 and 23 mesh with each other as shown in FIG.

By repeating the above operation in a state where the printed board 14 is inserted into the connector 12, one side of the printed board 14 eventually fits into the guide groove 17a of the board guide 17, and the movable board guide 17 and the housing The substrate guide 11 fixed to the body 10 is sandwiched. In the present embodiment, since the depth d of the guide groove 17a of the board guide 17 is formed larger than the pitch p of each of the V-shaped concave and convex grooves 21 and 23, the printed board 14 is formed.
Can be reliably supported. The V-shaped concave and convex grooves 21
The top of the convex portion of V
Since it is necessary to get over the top of the convex portion of the concave / convex groove 23, the width w of the T-shaped groove 22 is slightly conservative in consideration of the thickness of the plate portion 20 and the height h of the convex portion of the V-shaped concave / convex groove 21. It needs to be large. On the other hand, the printed circuit board 14
Is removed from the connector 12 by using the arrow B described above.
What is necessary is just to pull the slide board guide 15 in the direction opposite to the direction. In the above example, the slide board guide 15 and the connector 12 have been described as being separated from each other. However, since the V-shaped concave / convex grooves 21 and 23 may be normally engaged with each other, Even when the printed board 14 is not mounted, there is no need to separately store and carry the slide board guide 15.

As described above, according to the present embodiment, a mechanism for sliding the movable board guide 17 and a mechanism for locking the board guide 17 are integrally formed with the corresponding connector 12. Therefore, the number of parts for the support mechanism can be reduced. Therefore, the size and weight of the electronic device can be reduced, and the electronic device can be easily assembled. Further, since the V-shaped concave and convex grooves 21 and 23 are used as a mechanism for locking the slide board guide 15, the lock and sliding of the slide board guide 15 can be easily performed.

In the present embodiment, the sliding mechanism and the locking mechanism of the movable board guide 17 are formed integrally with the connector 12, but the effect from the viewpoint of the number of parts and the assembling work is weakened. However, it is possible to obtain an effect in terms of miniaturization and weight reduction of the electronic device even if it is provided along the side of the device or attached to a connector.

In this embodiment, the V-shaped concave and convex grooves 21 and 23 are used as the slide board guide locking mechanism.
2. Although provided on the entire slide portion 19, the V-shaped uneven groove 21,
If any of the portions 23 is engaged, the slide board guide 15 can be locked, so that, for example, a V-shaped concave and convex groove may be formed only in a necessary portion such as only the tip portion of the slide portion 19. Further, even if the concave and convex grooves are not V-shaped,
Irregular grooves of about character or sine wave may be used. In the present embodiment, the V-shaped concave and convex grooves 21 and 23 are engaged with each other by utilizing the spring property of the material of the slide portion 19 to lock the slide board guide 15. With this structure, it is possible to form even an inexpensive and easily moldable material such as plastic. Also, it is not necessary to lock the slide board guide 15 with a strong force, and since the printed board 14 is not frequently inserted and removed, it is considered that there is no particular adverse effect even if a durable or easily wearable material is used. Can be Of course, it is not denied that the slide substrate guide locking mechanism has a structure in which the concave and convex grooves are securely engaged by applying a small amount of force.

In the present embodiment, the printed circuit board 1
Although the case where the connector 4 is inserted into the connector 12 in an upright state has been described as an example, it is needless to say that the present invention can be applied to an electronic device that is inserted from the side. In the present embodiment, the direction of the electronic device for performing the work of holding the printed circuit board 14 is not affected at all.

Embodiment 2 In the first embodiment, the printed circuit boards 14 having different widths are supported by being held in the width direction. Usually, only support in the width direction is sufficient, but in electronic devices that can be carried around,
The printed circuit board 14 is connected to the connector 12 due to vibration or collision.
There is also the possibility of leaving. Therefore, it is certain that the printed circuit board 14 is supported from the height direction perpendicular to the width direction, but the height differs depending on the type of the printed circuit board 14. Therefore, in the present embodiment,
A printed circuit board 14 can be reliably supported by providing a board guide that is movable not only in the width direction but also in the height direction.

FIG. 6 is a perspective view showing the overall structure of a second embodiment of the substrate supporting mechanism for electronic equipment according to the present invention.
In short, in the first embodiment, the slide board guide 15 that slides on the basis of the connector 12 is provided. However, in the present embodiment, the slide board guide 15 is provided.
And a slide board guide 25 movable in the height direction is provided on the basis of the above. The slide board guide 25 has a board guide 26 for supporting the printed board 14 from the height direction and a slide portion 27 for moving the board guide 26. On the other hand, the board guide forming section 18 is provided with a slide guide section 28 for guiding the slide board guide 25 to slide in the height direction of the printed board 14 while engaging with the slide section 27. The slide guiding section 28 provided in the board guide forming section 18
And a slide portion 27 provided in the substrate guide forming portion 18
Are the same as those of the slide guiding portion 16 provided on the connector 12 and the sliding portion 19 provided on the slide board guide 15 and the engagement relationship thereof. Details are omitted because they are only different. That is, V-shaped concave and convex grooves 29 and 30 are formed in the engagement portion between the slide portion 27 and the slide guide portion 28, respectively.

The operation of the present embodiment in association with the engagement of the V-shaped concave and convex grooves 29 and 30 is the same as that of the first embodiment described with reference to FIG. ,
The printed circuit board 14 is provided on the board guide 26, but is partially held by the connector 12 and the board guide 26 when a part of one side of the printed board 14 is fitted in the id groove 26a.

According to the present embodiment, it is possible to support not only the width direction but also the height direction by a simple sliding operation of the slide board guides 15 and 25 regardless of the size of the printed board 14.

[0029]

According to the present invention, the mechanism for sliding the movable board guide is arranged near each connector, so that even if the number of boards to be supported increases, the support of the board can be achieved. An increase in the space required for the mechanism can be prevented. In particular, if the slide guiding portion is integrally formed with the connector, and the V-shaped concave and convex groove for locking the slide board guide is also integrally formed with the connector, the components necessary for supporting the board are formed by the formed connector. And a slide board guide. For this reason, the size and weight of the electronic device can be reduced. In addition, the support mechanism for the base can be provided at a low cost, and its assembly is extremely simple.

Further, since a V-shaped concave and convex groove is formed in the engaging portion on the side to be slid, the slide board guide can be easily slid without loosening or tightening the screw. Can be locked.

In addition, a simple sliding operation of the slide board guide and the height slide board guide can support not only the width direction but also the height direction regardless of the size of the board.
