FIG. 8 shows a rail member 70 according to another embodiment.
FIG. 8A is a side view showing a state where the second substrate 10 is fitted to the rail member 70, and FIG.
Is a sectional view taken along line II-II of the rail member 70 of FIG.
8 (3) is a cross-sectional view of the rail member 70 of FIG. 8 (1) as viewed from a section line III-III. The rail member 70 includes, similarly to the above-described rail member 34 shown in FIG. 4, a rail portion 36 in which a concave portion is formed and two coupling portions 37 that couple the rail portion 36 to the substrate portion 31. 31 are formed in the longitudinal direction, and the formation position of the vibration suppressing member 80 is different. Therefore, the configuration other than the vibration suppressing member is the same, and the description is omitted, and the same reference numerals are given.

A second groove 44 cut out in the thickness direction is provided from the portion of the protrusion 36c facing the rail groove 43, and a third groove 44 cut out in the thickness direction from the portion of the bottom portion 36b facing the rail groove 43. A groove 45 is provided. Rail part 70
When viewed in a cross section orthogonal to the longitudinal direction, a U-shaped groove is formed by the second groove 44 and the third groove 45.
The U-shaped vibration suppressing member 80 is fitted into the U-shaped groove. The vibration suppressing member 80 is disposed so as to fill the U-shaped groove and protrude in the thickness direction of the protruding portion 36c and the thickness direction of the bottom portion 36d. The portion protruding from the rail groove 43 is chamfered. Thus, the second substrate 10 moving in the rail groove can move smoothly without being caught by the vibration suppressing member 80.

More specifically, the portion protruding from the protruding portion 36c protrudes from the protruding portion 36C, and is chamfered so that both ends 81 in the longitudinal direction of the rail member are close to each other. The portion protruding from the bottom 36b is the bottom 36B
And is chamfered so that both ends 82 of the rail member in the longitudinal direction are close to each other.

The vibration suppressing member portions 83a and 83b which protrude most from the respective protruding portions 36c are formed such that the distance between them is shorter than the dimension in the thickness direction of the second substrate. When the second substrate 10 is inserted between the vibration suppressing member portions 83a and 83b, the vibration suppressing member is elastically deformed, and holds the second substrate 10 from both ends in the thickness direction. Similarly bottom 36
When the second board 10 is inserted into the vibration suppressing member portion 84 that protrudes most from the bottom b, the second board 10 is pushed up in the thickness direction of the bottom portion, and cooperates with the guide rail of the rack 1 to form the second board 10. From both ends in the width direction.

As described above, according to the present embodiment, the second board 10 can be easily mounted without performing any special processing on the conventional rack 1 and the second board 10. As a result, boards and racks specified by standards can be used. In addition, since the rack 1 is not processed, the substrate having the predetermined width L1 can be mounted on the rack 1 again by releasing the mounting of the conversion adapter. As described above, the mounting and releasing can be easily performed using the substrate specified by the standard, and the substrate having the predetermined width L1 and the second substrate 10 can be mounted flexibly. , Repairs and changes in board configuration are facilitated.

Further, since the connector 11 of the second board 10 is directly connected to the receiving connector 9 of the rack, the electrical connection is more complicated than when the connector 11 and the receiving connector 9 are connected via a wiring portion. The second substrate can be mounted on the rack without deteriorating the characteristics. Specifically, when the rack 1 and the second board 10 are regulated by the VME standard, the single-height VME board as the second board is fitted into the other guide rail 3a of the rack 1,
It is arranged to be biased to the other side. In such a mounted state, the connector 11 of the single height VME board is arranged at the same position as one of the connectors of the double height VME board. Thus, the connector on the second substrate can be directly connected to the connector in the electronic apparatus. Therefore, there is no need to connect via wiring,
No space is required for the wiring section, and the second
Substrate 10 does not protrude.

Further, by being directly connected to the receiving-side connector 9, the mechanical connection force between the second board 10 and the rack 1 can be improved. One side 10a in the width direction of the second board 10 is fitted to one guide rail 3a of the rack 1, and the other side 10b in the width direction of the second board 10 is fitted to the rail 34 of the conversion adapters 30 and 60. Fit. Therefore, both sides of the second substrate 10 are supported, and the second substrate 10
Is suppressed.

Further, a vibration suppressing member 36a, 80 having flexibility and elasticity such as rubber is provided on the rail portion 34,
Since the vibration suppressing members 36a and 80 abut the second substrate 10, the vibration of the second substrate 10 is further prevented. Further, the holding portion 36 d of the rail portion 34 is held by the connecting portion 37, and the connecting portion 37 is connected to the board portion 31. Therefore, the coupling portion 37 functions as a spring mechanism, and absorbs an external impact and transmits the impact to the second substrate 10. Further, when the dimensional accuracy of the second substrate 10 is low and due to thermal deformation, etc.,
Even if the second substrate 10 is deformed, the coupling portion 37 bends to cope with the deformation, to prevent the second substrate 10 from being subjected to an excessive force, and to prevent the second substrate 10 from being damaged. Can be. Further, since the rail portion 34 is fixed by being held by the grip portion 36d, compared with a case where the rail portion 34 is directly fixed to the second substrate 10 by screwing or the like,
The rail portion 34 can be finely adjusted.

In the electronic apparatus having the rack 1 on which the conversion adapter 30 is mounted, the replacement of the second board 10 is easy, and the configuration of the board can be easily changed. In addition, vibration of the second substrate 10 incorporated in the electronic device is prevented, and an electronic device that is stable against vibration can be provided. Further, since the second substrate 10 can be easily removed, the second substrate 10 can be easily removed for repair and replacement, and damage to other substrates can be prevented.

The present embodiment is merely an exemplification of the invention, and the configuration can be changed within the scope of the invention. For example, by making the guide rail portions 3a and 3b of the rack 1 the same as the configuration of the rail portion 34, vibration of one side portion 10a in addition to the other side portion 10b of the second substrate 10 is suppressed, and the first side portion 10a is more reliably formed. The vibration of the second substrate 10 can be prevented. Further, the second substrate may be fixed by a member made of metal without using the vibration suppressing member 36a. Further, the conversion adapter does not need to have a rectangular plate-shaped board portion, and it is sufficient that the conversion adapter can be fitted to the guide rail of the rack on one side in the width direction and the rail portion is formed on the other side in the width direction. Alternatively, a lattice structure may be formed instead of the substrate portion.

The second board mounted on the rack 1
They may be arranged vertically or horizontally. In addition, the board and the rack can obtain the above-described effects even in a case other than the VME standard.

According to the first aspect of the present invention, the second substrate can be mounted on the rack without requiring special processing and members. As a result, a commercially available ordinary board can be used as the second board, and can be easily mounted on a rack. The second substrate is
Since both sides are supported, it is possible to prevent the substrate from being largely shaken by an external impact, and to reduce damage to the substrate due to vibration.

Further, there is no need to process the rack itself, and the first substrate and the second substrate can be flexibly mounted according to the configuration of the substrate. With this, it is possible to configure an electronic device having a variety of board configurations,
In addition, the configuration of the substrate can be easily changed.

Further, the connector of the second board and the bus connector in the electronic apparatus can be directly connected to each other without wiring, so that they can be mounted on the rack without deteriorating the electrical and mechanical characteristics of the board. can do. For example, since no wiring is required, the effect of noise can be reduced and stable performance can be maintained. Further, by connecting the connectors, the board can be more firmly connected to the rack.

According to the second and third aspects of the present invention,
Vibration of the second substrate is suppressed, and damage to the substrate due to vibration can be reduced. Thus, a failure due to vibration of the electronic device on which the second substrate is mounted can be eliminated, and stability can be improved.
